Panel and coating of floor

FIELD: construction.

SUBSTANCE: floor panel with a face surface comprises four edges, opposite pairs of which comprise corresponding retention profiles to connect panels of single type at all four edges. Retention profiles of the first pair of edges are connected by means of insertion at an angle, and retaining profiles of the second pair of edges are arranged in the form of coupled hook-shaped elements. On each of hook-shaped elements the neighbouring panel is connected substantially by means of motion executed in the plane perpendicularly to the panel plane, provided that at least one of hook-shaped elements of the second pair of edges there is a separate vertically locking element, which at least partially enters into a track of connection of hook-shaped elements. During a connecting motion of hook-shaped elements of two panels, a vertically locking element automatically comes out of the connection track to release it, and in the engaged position of the hook-shaped elements it automatically again enters the track connection due to a springy action. To simplify dismantling, it is provided that coupled hook-shaped elements are arranged as capable of unlocking joined panels from their engaged and vertically blocked condition, at the same time at least one panel is arranged as capable of rotation along the axis stretching in the zone of engaged edges in a direction, in which unlocked position is achieved. Face surfaces of panels in the unlocked position form an angle between each other that is less than 180°.

EFFECT: reduced labour inputs in assembly and disassembly of a floor coating.

The invention relates to a panel with a front surface and four edges, opposite pairs of which are related to each other holding profiles for compounds of similar panels on all four edges, and the retaining profile of the first pair of edges are connected by inserting at an angle, and the retaining profile of the second pair of edges is made in the form of paired hook elements, so that each of the hook elements of the same type adjacent the panel is connected essentially by connecting the movements performed in the plane perpendicular to the plane of the panel, due to the fact that at least one of the hook elements of the second pair of edges, there is a separate vertical locking element, at least partially entering the path connection hook elements, and during the joining movement of the hook elements of two panels vertically locking element is automatically released from the connection path, to release him, and in the coupled state of the hook elements will automatically re-enters the path of the connection through the springing action.

In addition, the invention relates to a floor covering consisting of a set of proposed panels.

Known panels of the described kind is known from WO 03/016654 A1 and WO 2006/043893 A1. And the both publications specialist known panel, stacked, for example, ranks, and within one of a number of panels are interconnected at joints. The best way known panels are laid so that the joints of the panels of one row are located at a distance from the joints of the panels adjacent rows. In the new row of the panel is connected to the panels of the previous row by the so-called rotation. The term "insert at an angle. Einwinkeln) is called the type of connection where the new panel puts one edge to the panels of the previous row, and a new panel is added relative to the plane of the previous row in an inclined plane. Lock the new panel is due to angular motion, during which the new panel is rotated downward in the plane of the panels of the previous row.

In that case, if in a series, in which fit the new panel has a panel, a new panel during the described movement of the insertion angle turn connects to the panels of the previous row at the same time also with a panel of the same number. To this end for connection of the panels within the same series are related to each other holding the profiles of the edges made in the form of hook elements, which are in the direction perpendicular to the plane of the panels may converge and, thus, to be linked. The movement in the said vertical p is Ascoli is the movement type of scissors. It can be called folding movement.

Known panels contain at least one hook element is automatically latched vertical locking element, which complicates the separation of the panels to remove, because it is impossible to move from its blocking position or you can, but with a special tool. In WO 03/016654 provided by removing the vertical locking element from the connection side, coupled to the panel could then push in the direction perpendicular to them. In WO 2006/043893 A1 it is proposed to use instead of retrieving the vertical locking element is a special tool through which the vertical locking element can be removed from its blocking position, so that then possibly extracting panels perpendicular to their plane. In the case of a special tool we are talking about the kind of needle that is inserted laterally into the slot, in which is vertically locking element. Therefore, it is necessary to properly insert thin as a needle, a special tool, the upper and lower sides of which are different, in the slot, in which is vertically locking element. The third method of unlocking is to push the United hook elements in the plane of the panels, namely pairs is lelno coupled edges. However, this method is unsuitable for such panels, between the hook elements having high friction clutch and which move so only with great effort.

The basis of the invention lies in the task of creating easy-to-install panels and, in addition, easier removal of the floor covering, consisting of panels of the type specified above.

According to the invention this problem is solved due to the fact that the mating hook elements are made so that if two connected panels, they are released from his chained and vertically locked state, and at least one panel by passing through the coupled edges axis rotates in the direction in which achieved an unlocked position, and the front surface of the panels in the unlocked position form an angle of less than 180°.

Thanks to the proposed panel is not required to extract the vertical locking element of the connection and to use a special tool to remove the blocking function of the vertical locking element to remove the floor covering. According to the invention the hook elements are made so that the panels of one series can be separated when they are no longer connected to the panels adjacent rows. If you want to separate from each other panel one is about the number, it should first be disconnected from adjacent rows. Then you can dismantle the panels of the same number due to the fact that the panel is connected only at one end within the series, turn up this late, and the previous panel, from which it must be separated, not moving.

In principle, this movement of the unlock of panels of the same row corresponds to a movement reverse to that described above as rotation and through which the new panel is connected to the panels of the previous row.

Because the connection of the new panel with the panels of the previous row occurs simultaneously with the connection of the new panel with the existing panel in the same row, these compounds can affect each other. For example, it may be preferable, if the motion type of scissors (folding movement) of the new panel is regulating the position of the concatenated edges relative to each other. This requires then sliding movement within the inserted one into each of the edges of the first pair of edges participating panels to concatenate edges of the second pair of edges during folding movement to result in the desired position. Hook elements can be made so that due to their shape was automatic positioning of their edges. Then the automatic positioning is initiated p. the tool folding movement of the new panel.

The proposed panel can be performed, for example, in the form of floorboards, parquet or laminate panel and can be due to either of solid wood or contain the core material. The core material may be of wood material, consisting of wooden parts, for example consisting of wooden bars countertop, consisting of wood layers multiplex stove, or plywood. On the other hand, as the core material, it may also include a fibrous material. It means the wood, which was first shredded into fibers, and then by adding a binder recycled into wood-fiber material, such as MDF, HDF, plywood or OSB. Of course, for the proposed panel as well to other materials, such as solid plastic or at least plastic as core material.

If the panel contains the core material, it has a floor and, as a rule, the front surface with decorative properties.

The invention is particularly preferred if the panel consists of an adult deprived of the fibers of the wood material, such as solid wood or wood material devoid of fibers of the wood material. The retaining profiles, in particular the hook elements of the adult is assignee wood or deprived of the fibers of the wood material, have a blocked state due to the nature of its surface, high adhesion between themselves and hardly separable. Consequently, the above-mentioned known from the prior art the third method of unlocking is not suitable for such panels. Thus, the proposed unlocking particularly practical for panels of solid wood or panels with a core material, which in the sense of the invention is a stripped fibers of the wood.

The retaining profiles of the first pair of edges, it is advisable to have on one edge polnotsennyi profile-groove, and on the opposite edge of the mating profile-crest, connected to each other by rotation. In the prior art it is known a large number of such polnotsennyh profiles-grooves and profiles of the ridges, which are connected by rotation and are therefore suitable for the proposed panel. The known geometry of the retaining profile can therefore be provided on the first pair of edges and combined with the proposed hook element on the second pair of edges.

Completeness sake, it should be said that the hook elements of the two panels are always connected even when the two joined panels lie in one common plane. This hook element of one panel is placed over the hook element of the neighbour her panel, in the result section of hook elements lie one behind the other, exactly coinciding. Then provided with hook elements edges are inserted into each other, until they do not overlap on the desired length of the panels. In this method of installation reference should be made to Fig. 44 publication DE 102006011887, which shows his example. In this example, the edge 32 of the panel 30b is connected on the arrow on the edge of the panel 30A. Under certain circumstances, at the beginning of the matching movement necessary to slightly press down on the protruding edge of the elastic vertical locking element and, respectively, to burn, so he went into the adjacent panel.

In one alternative implementation of the panel, the retaining profiles of the first pair of edges instead of the above-described modified profiles of grooves and profiles of the ridges made in the form of mating hook elements, and at least one of the hook elements of the first pair of edges, there is a separate vertical locking element, vertically locking element acts on the flexible type of comb from the edge of the panel, the mating hook element is designed in the form of the locking recess groove, and at least part of the flexible speaker crest vertical locking element is inserted into the groove of the mating hook element. Because the ku movement to remove panels of the same number, as already mentioned, is a movement opposite to the turning movement, you can use any of the proposed panel and any of the vertical locking elements to respectively perform the retaining profiles of the first pair of edges and use them to connect the panels with the panels of the previous row. Important to connect to, and protruding from the edge of the panel segment is vertically locking element should be considered in this context in its broadest sense, flexible comb. This part of the vertical locking element may have a cross section that is close to the cross-section of traditional crest or very different from it. The decisive factor for vertically locking element with its flexible comb is its blocking function in the direction perpendicular to the plane of the panels and its suitability for their connection.

Positive, if at least one of the pairs of edges match each other hook elements, each of which has at least one polnotsennuyu surface, polnotsennie surfaces of both hook elements are arranged so that they are in coupled condition of two panels are located on the same General curve unlock and are in contact with each other, and polnotsennie surface on a common curve unlock move away from each other and meet on the corner to the other.

Location polnotsennyh surfaces on one curve unlock contributes to the dismantling of the panels, as a result of deformation of the retaining profiles of the panels does not occur any load or at least a small load.

The handling of the panels may be improved if one hook element for the purpose of connecting with the mating hook element adjacent panel positioned on the base, and the connection of the hook elements of the two panels is due to the fact that positioned on the basis of the fixed panel, and with the adjacent panel is connecting movements, with the vertical locking element is provided mainly in that the hook element, which is located on the edge of the fixed panel.

Was that the hook elements engage more receptive to the user, if vertical locking element is located on the bottom of the fixed panel. In addition, this has the advantage that the vertical locking element when it is located on the bottom panel, it is better visible for the user. Therefore, preferably, if the movement of the vertical locking element, caused initiated by the user connecting movement of the hook elements, is also visible to the user.

For an easy handling of the panel vertically locking element can move pruinose-elastic. The ability pruinose elastic movement may be provided pruinose-elastic properties of the vertical locking element or a separate spring element, which interacts with the vertical locking element.

To ensure at least the possibility pruinose elastic movement of the vertical locking element may be provided in the plane of movement parallel to the plane of the panel.

Vertical locking element located in the plane of motion parallel to the plane of the panel, has not, as a rule, constant spring properties along its entire length. Located parallel to the plane of the panel vertically locking element has, however, generally good mechanical properties under vertical loading provided they join, because it can have a relatively large cross section.

Alternatively, to ensure at least the possibility pruinose elastic movement of the vertical locking element is provided by the plane of motion, which is perpendicular to both the plane of the panel and the edge, equipped with a vertically locking element.

In this case pruinose-elastically movable portion of the vertical locking element, because it is placed in the plane perpendicular to the panel must be made relatively little the about section. The height of the vertical locking element does not exceed, as a rule, half the thickness of the panel. Currently distributed vertically locking elements that, when the minimum design panels have a height that corresponds roughly to one-third the thickness of the panel.

Especially preferred is the panel, if provided the core material made of HDF (high density fiberboard - hardboard plate high density). These core materials are made from crushed wood with the addition of a binder. They are very well handled by cutting and have sufficient strength to accommodate the proposed retaining profile and add a separate vertically locking elements. As already mentioned, the panel may also consist of other materials.

In the United state of two panels inside connections restraint profiles can be provided by at least one dust Luggage. It enables mud particles, which while laying the floor covering can penetrate into the connection holding profiles, can not violate the optimum planting of the United restraint profiles.

In the United state of two panels of the retaining profiles can be partially bent, and the bending creates a tension force acts is relevant in the plane parallel to the plane of the panel. Depending on the desired position of the panels with respect to each other, the tension force can be calculated so that they pressed against each other or were maintained at a desired distance from each other.

Alternatively or additionally, the retaining profile in the United state of two panels can be partially bent so that the bending creates a tension force acting in the plane perpendicular to the plane of the panel. Thus, the United panels can be positioned at a height relative to each other so that they pressed against each other or were maintained at a desired distance from each other.

In the United state of two panels with vertical locking element is created tension force, and it acts in a plane parallel to the plane of the panel. Depending on the required tension force of the vertical locking element can provide pressing of the panels to each other or regulation necessary distance between them.

Alternatively, or additionally in the United state of two panels with vertical locking element is created tension force, and it acts in a plane perpendicular to the plane of the panel and perpendicular to the edge, equipped with a vertically locking element. Therefore clicks the zoom, depending on the direction of stretch of the efforts of the vertical locking element panels can optionally be loaded force component which presses on one panel relative to the connected panel perpendicular to the plane of the panels up or down.

A simple way of retaining profiles of the panels made in one piece with the core material. This can be done, for example, by cutting.

The proposed floor containing a variety of compatible panels described species, interconnected.

In one particular implementation of a floor covering is provided that a separate panel for disassembly can be unlocked with low friction and that unlocked the panels can be re-connected in the floor. In the case provided for this panel we are talking about one of the above options panel, and it can be unlocked with low friction.

In principle, the vertical locking element can be connected with the corresponding hook element through a light press fit or by adhesive bonding. It is also possible to combination of extrusion and adhesive joints. When you do this enough, if due to this press-fit connection vertical locking element is fixed to the hook element without falling out. If op is edelenyi circumstances press fits unwanted, because of this in the core material of the panel entered efforts, leading to undesirable deformation. In particular, it is a disadvantage when this deformation is visible from the finished floor surface, as, for example, on the front surface of the panel occurs forming. Adhesive bonding is considered, of course, only in the case of the vertical locking element having a mounting portion which must not move with the prisoners in the hook element of the plot, i.e. if, therefore, there pruinose-elastically movable section, which is not affected by the core material of the panel and which can move freely.

From the publications WO 2006/043893 A1 and WO 2006/104436 A1 famous pruinose-elastic, automatically operating locking elements (brakes). The locking elements preventing exclusively divergence panels perpendicular to its plane is vertical locking elements are in principle applicable in the present invention. Mentioned vertically locking elements with reference to the publication WO 2006/043893 A1 and WO 2006/104436 A1 included in the present description and in the quality of the vertical locking element is in the independent claim.

In Fig. 1 shows Acala paving In the floor of the proposed panels. Two rows R1, R2 of the same type of panels 1-5 are depicted in the form of fragments.

Panel 2 is rectangular in shape. It is equipped with a front surface N, and on the four edges of the panel 2 are holding profiles 2a, 2b, 2c, 2d. Panel 2 has two pairs of edges. Each pair is formed by two opposite edges which are not consistent with each other retaining profiles. In this example, the panel 2 has two parallel long edges 2A, 2b, and two opposite parallel short edges 2c, 2d. Short edges 2c, 2d panel 2 is connected to other panels 1, 3, lying in the same row R1. Indexing edges applies equally to the rest of the panels 1, 3, 4, 5. Long edge 2b of the panel connected to the panels 4, 5 of the next row R2. Each stacked row of panels may be attached a new row of panels. This is mainly due to the inclusion of individual panels step by step education of a new row of panels.

In Fig. 1 shows how the pad 5 as the new panel is connected with the panels 2, 3 of the previous row R1 by inserting at an angle. The new panel 5 is depicted in the plane located obliquely to the plane of the panels 2, 3 of the previous row R1. Long edge 5b of the new panel 5 attached to the long edges 2b, 3b, panels 2, 3 of the previous row R1. Inserted into each other long edges of the retaining profiles of the first pair of edges are automatically locked to each other by rotation of the new panel 5 in the plane of the panels of the previous row R1. The retaining profiles of the long edges of the panels then prevent the divergence of the panels in a common plane, namely perpendicular to the long edges.

At the same time, the rotation also causes the connection of the short edges 5C of the new panel 5 with the short edge 4d, already lying in the same row R2 panel 4. During turn on short edge 4d, 5c there is a movement by type of scissors, in which the short edges 5C of the new panel 5 is approaching the short edge 4d of the panel 4. Due to lock the short edges turn is also called the folding movement.

In Fig. 2A-2E depict the shape of the retaining profiles, which are known from the prior art and suitable for insertion at an angle to the rotation.

Typically, the flange And groove panels of the previous row is intended for connection of the next row of panels. Therefore, as a rule, equipped with a crest edge In the new panel added to the edge And groove panels of the previous row, and the new panel is located in an inclined plane, as shown in Fig. 1. The edge And the groove has at least one polnotsennuyu surface A1 and the edge with a crest at least one polnotsennuyu surface B1, which in the locked condition prevents the divergence of the panels in their plane, namely perpendicular to the blocked edges And, B. the Upper side panels SN is beena face (working or useful) surface N.

The panel of Fig. 3a-15b contains the core material from wood material. The retaining profiles are cut in the edges, which may consist of a core material or contain special edging material.

In Fig. 3a-15b retaining profiles are depicted in the form of hook elements 6A, 7a. These hook elements are at least one pair of edges of panels 1-5 in Fig. 1, which connects with similar adjacent panel 1-5 due to the motion-type scissors (folding movement). All examples of hook elements in Fig. 3a-15b fit thereby to edges 2c, 2d panel 2 in Fig. 1 and concatenate edges 4d, 5c homogeneous panels 4, 5 in Fig. 1.

The use of hook elements 6A, 7a in Fig. 3a-15b for movement by type of scissors is not, however, the only possible form of connection, as explained below.

All the examples in Fig. 3a-15b inherent in the preferred form of connection where the new panel 7 shown in Fig. 3A in the form of the fragment indicated by the dashed line of the upper hook element 7a, due to the motion type of scissors is applied to the lower hook element 6A adjacent panels 6 and bonded with him. Below is facing surface of the N hook element is always called the upper hook element 7a, and the mating of crycooler the element - accordingly, the lower hook element 6A.

On indicated by the index "a" of Fig. 3A-15A floating-type shear panel shows the stroke of the upper hook element 7a; on the other hand, a solid line shows the final coupled position of the upper hook element 7a in the lower hook element 6A. In the coupled position located inside connections vertically locking (locking) item 8 automatically clicks into place and prevents the divergence of the two panels 6, 7 perpendicular to their plane.

To the panels 6, 7 are not dispersed in its plane, namely perpendicular to the coupled edges, the hook element 6 is supplied polnotsennoi surface 6b, which interacts with polnotsennoi surface 7b of the panel 7.

To again disconnect the connection in Fig. 3A, panel 7, indicated in Fig. 3A by the dashed line, is rotated in Fig. 3b upward in an inclined position and, thus, is in the unlocked position. The movement of rotation is around an axis of rotation parallel to the hook elements 6A, 7a, or around curves V1, V2 unlock, which in this example is circular, but may also differ from a circular shape. In the unlocked position of the front surface N of the two panels 6, 7 form an angle of less than 180°.

This way up is sufficient to rotate the panel 7 up with the aim of unlocking so, to polnotsennie surface 6b, 7b hook elements 6A, 7a, which prevent the divergence of the two panels 6, 7 in their plane, namely perpendicular to the coupled edges, slipping past each other to the exit of the contact between them. Then the panel 7 will be removed.

In Fig. 3A, 3b provides a vertical locking element 8, which is elastically springing the locking lug 8A, pruinose-elastically moving in the plane of section of Fig. 3A, 3b. Vertical locking element 8 has an insertion section 8b, which sits in a recess 6 provided for this purpose in the edge of the hook element 6A. In this case, the recess 6C performed two with a narrow and deep plot, as well as with the broader area of less width. The holes of the locking lug recesses 8A vertical locking element 8 protrudes from the edge of the hook element 6A. Pruinose elastic locking tongue 8A comes into the path M of the compound (splicing), which is indicated by the dashed line hook element 7a must move to reach the coupled position of Fig. 3. Plug-in area 8b is without a fall in the hook element 6A panel 6.

The path M of the connection of the upper hook element 7a is released under the action of its return pressure. After eliminating the response pressure of the fixed what would be the tongue 8A by the accumulated elastic energy again spontaneously comes into the path of the M connections and blocks it.

Where the vertical locking element 8 comes into the path M of the connection provided by the dust chamber S to possible dust site inside connections could penetrate into areas where it does not disturb the functioning of the hook elements 6A, 7a and the vertical locking element 8. These dust chamber S can be provided in all of the examples in Fig. 3a-15b.

The lower hook element 6A has a landing surface b, which in coupled condition is in contact with the seat surface with the upper hook element 7a. Thanks docked to each other landing surfaces b, with the surface In a continuous, since the front surface of the N one panel directly adjacent to the front surfaces of the N adjacent panels. Of course, the angles between the fitting surfaces b, can be performed also chamfered or rounded.

Between the free outer edge of the lower hook element 6A and spaced back from the outer edge portion of the upper hook element 7a in coupled condition provides a gap l. When mounting hook elements 6A, 7a, the user feels good pruinose-elastic automatic snap vertical locking element 8, as it is the only resistance provided by connecting the movement to the Oia on the path M of the connection.

To spring the locking lug 8A, the connecting motion is automatically lowered, and it will be released, from the path M of the upper connection is indicated by the dashed line hook element 7a, could carry out the lock on the outer edge of the upper hook element 7a is provided by the locking recess 7C. The locking lug 8A spontaneously and pruinose-elastic gets it going, so again M connection of the upper hook element 7a. When the locking lug 8A prinimaet to beveled clamping surface d of the locking notches 7C.

Polnotsennie surface 6b, 7b hook elements 6A, 7a are arranged so that they were lying on the curve V unlock. In this case polnotsennie surface of the hook elements are cylindrically curved shape. However, there are also flat or curved counter polnotsennie surface. In this case, they are in certain conditions, be subject to elastic deformation during movement of the panels from a flat position to an unlocked position in Fig. 3b. The elastic deformation can be neglected, if it does not impede the functioning of the hook elements.

The front surface of the N panels 6, 7 are at the same height. When you load the front surface of the N in the area of the top cu the crustacean leaves item 7a its contact surface 7w presses on the bearing surface 6w lower hook element 6A. In coupled condition of the hook elements 6A, 7a of the contact surface 7w and bearing surface 6w are in contact with each other, so that there cannot occur any difference in height due to the cavity between the contact surface of 7w and the bearing surface 6w. In addition, as indicated in Fig. 3A, the dashed line on the contact surfaces can be provided for dust S camera, which applies to all examples in Fig. 3a-15b.

With the help of Fig. 3C revealed an additional object, which lacks the ability to easily unblock hook connection. The panel with such modified hook elements 6A, 7a has a particularly high strength (horizontal) divergence with the linked panel in their plane, namely perpendicular to the coupled edges. This polnotsennie surface 6b, 7b, preventing mentioned horizontal divergence of the panels 6, 7 are not arranged on the curve unlock. Of course, this can be provided in all of the examples of execution hook elements in Fig. 3A-15A, if we abandon the possibility to unblock the axis of rotation or curve unlock.

Another example of hook elements depicted in Fig. 4A, 4b. It differs from the example in Fig. 3a, 3b, only the fact that the gap l is absent, and instead, OEM home button Flex cable is TREN contact edges. In Fig. 4A hook elements 6A, 7a are polnotsennie contact surface 6d, 7d, made so that during the vertical joining movement in Fig. 4A required pressure and elastic deformation to bring the contact surface in the shown position of the contact. In addition, the contact surface 6d, 7d executed so that to achieve is shown in Fig. 4b unlocked position they can slide past each other without appreciable elastic deformation. When this contact surface 6d, 7d are subjected to less wear than during the joining movement.

In the example of Fig. 5a, 5b provides the same vertical locking element 8, as shown in Fig. 3A, 4A. Connecting movement to clutch hook elements 6A, 7a of the two panels 6, 7 is also a movement by type of scissors, in which the panel 7 with the top marked by the dashed line hook element 7a is coming to the panel 6 with the lower hook element 6A. On the free outer edge of the latter provides a gap l to the shifted back edge of the upper hook element, as in Fig. 3A. Fig. 5A differs from the Fig. 3A number polnotsennyh surfaces of the hook elements, which prevent the divergence of the panels in their plane, namely perpendicular to the coupled edges (horizontally). In Fig. 5A ka is every hook element 6A, 7a has two polnotsennie surface 6b, 6e and 7b, 7e, located on the two curves V1, V2 unlock. Due to the fact that each of the hook elements 6A, 7a are provided with two lying one behind the other odnotrahniki surfaces, achieves higher robustness against differences panels 6, 7 in the horizontal direction, namely perpendicular to the coupled edges.

In Fig. 5b polnotsennie surfaces are made so that they provide no problems turning the panel 7 with the upper hook element 7a in the unlocked position in which the front surface of the N panels 6, 7 form an angle of less than 180°.

Another example is shown in Fig. 6a, 6b. It differs from the example in Fig. 5a, 5b, only those that are equipped with vertical locking element 8 panel 6 with the lower hook element 6A at its free outer edge occurs contact with receding edge of the upper hook element 7a adjacent panel 7. Provided polnotsennie contact surface 6d, 7d, when connecting traffic by type of scissors along the path M of the compound (Fig. 6A) due to the elastic deformation of the fall in its locked position. The contact surface 6d, 7d have in the United state blocking action from the divergence of the panels 6, 7 in the vertical plane, which is connecting the e movement.

In Fig. 6b clearly shows that the described contact surface for the purpose of unlocking or for connection of hook elements 6A, 7a through rotation can slide past each other.

In Fig. 7a, 7b depicts an example of hook elements 6A, 7a of which is indicated by the dashed line in Fig. 7a hook element 7a provided with a vertical locking element 8 and at the expense of connecting traffic by type of scissors is connected with the lower hook element 6A adjacent panel 6. Vertical locking element 8 is located at a spaced back from the outer edges of the top panel section 7 and interacts with the outside edge of the panel 6, provided with a lower hook element 6A. For this purpose on the outer edge of the lower hook element 6A is provided by the locking recess 6f with beveled clamping surface d. When the upper hook element 7a while connecting traffic by type of scissors is omitted from the indicated dashed line position on the lower hook element 6A, there is an automatic movement of the locking tongue 8A vertical locking element 8, which spring the locking lug 8A automatically one's pressing away from the path M connection first by contact with the lower hook element 6A. When the hook elements reach the its locked position in Fig. 7a, springing the locking lug 8A again spontaneously comes into the path M connection due to the fact that he gets formed in the locking recess 6f space and prinimaet to the fixing surface d.

In Fig. 7b hook elements 6A, 7a are polnotsennie surface 6b, 7b, (horizontally) interacting with each other to lock in the plane of the panels and perpendicular to the coupled edges. These polnotsennie surface 6b, 7b are located on the same curve V unlock. To separate the hook elements 6A, 7a of each other panel 7 with the upper hook element 7a is rotated around concatenated edges up and is in the unlocked position. In this position, the front surface of the N panels 6, 7 form an angle of less than 180°.

In Fig. 8a, 8b depicts another example. It essentially corresponds to the example in Fig. 7a, 7b. The only difference is the additional current in the vertical direction of the undercut. This undercut is provided on the free outer edge of the panel 7 with the upper hook element 7a. The free outer edge of the upper hook element 7a provided with a recess with a locking surface 7g. In the appropriate place shifted back part of the cutting edge of the panel 6, provided with a lower hook element 6A, dissolved the false protruding contact element 6g, which interacts with the locking surface 7g of the recess adjacent panel 7. In the form shown in Fig. 8A locked position, the hook elements 6A, 7a aimed at deepening the contact element 6g causes the lock from the divergence of the panels 6, 7 in the direction perpendicular to their plane. Unlocking is done in Fig. 8A is exactly the same as in the previous examples. It is seen that the additional blocking caused by the contact element 6g, along with a corresponding locking surface 7g deepening, to unlock extendible without the need for this elastic deformation of the contact area of the contact element.

The example of Fig. 9a, 9b essentially corresponds to the example in Fig. 5a, 5b, however, in the same installation location provides an alternative vertical locking element 8. He is bent on the type of flat springs and shaped so that it can be automatically pushed out of the way M connection of the upper hook element 7a and perceives elastic energy. When the two hook element 6A, 7a are shown in the locked position of Fig. 9a, the vertical locking element 8 is again automatically comes in a way M connection and enters the locking recess 7C hook element 7a.

Vertical locking element 8 is located in a plane parallel to the front surface is resti N panel 6. For this purpose the lower hook element 6A is provided patapata notch 6h. It runs along the receding part of the cutting edge of the lower hook element 6A. This is parallel to the front surface of the N plane is also pruinose elastic movement of the vertical locking element 8. In the hollow 6h vertical locking element 8 springs parallel to the plane of the panel, namely essentially perpendicular to the edge of the panel. In a weakened state he enters the path M of the connection of the upper hook element 7a. Since the vertical locking element 8 must be capable of movement in the recess 6h, he placed it with the ability to easily move. This prevents jamming. Vertical locking element 8 has a bevel 8C for movement, which serves as a contact surface for the upper hook element 7a. When the upper hook element 7a in its path M connection rests on the bevel 8C, the vertical locking element 8 in the form of a leaf spring elastically deforms and moves towards the base of the excavation 6h. Thus, the path connection for the upper hook element 7a is temporarily released. Between the free outer edge of the lower hook element 6A and spaced back from her portion of the upper hook element 7a in the coupled state the AI provides a gap l. When mounting hook elements 6A, 7a, the user feels good pruinose-elastic snap vertical locking element 8, as it is the only resistance provided by connecting the movement on the path M of the connection.

In Fig. 9b shows that alternative vertical locking element 8 also provides no problems unlocking due to the fact that is supplied with the upper hook element 7a panel 7 is rotated around curves V1, V2 unlock in the unlocked position in which the front surface of the N panels 6, 7 form an angle of less than 180°.

Depending on the speaker section vertical locking element 8 and forms the locking notches 7C, made on the outer edge of the upper hook element for placing elastic setting in the connection way and elastic coming out part of the vertical locking element 8, it may happen that as a result of movement of the unlock, as shown in Fig. 9b, the vertical locking element 8 will be slightly pushed into the recess 6h to turned upwards in Fig. 9b panel 7 could take the unlocked position.

In Fig. 10a, 10b depicts an example of essentially corresponding to the example in Fig. 9a, 9b. It differs from it only by the fact that the gap l is absent, and instead provides a contact to the of Omak. In Fig. 10A hook elements 6A, 7a are polnotsennie contact surface 6d, 7d, made so that during the vertical joining movement in Fig. 10A required pressure and elastic deformation to bring the contact surface in the shown position of the contact. In addition, the contact surface 6d, 7d executed so that to achieve is shown in Fig. 10b unlocked position they can slide past each other without appreciable elastic deformation. When this contact surface 6d, 7d are subjected to less wear than during the joining movement.

In Fig. 10b shows that the panel 7 with the upper hook element 7a is rotated upward around curves V1, V2 unlock to reach the unlocked position. In this case, all polnotsennie surface 6b, and 7b 6E, 7E hook elements 6A, 7a and described contact surface 6d, 7d move over each other with slip without causing appreciable elastic deformation of the hook elements 6A, 7a.

In Fig. 11a, 11b depicts an example of essentially corresponding to the example in Fig. 10a, 10b. Vertical locking element 8 is, however, kinematically Vice versa. This means that it is not shifted back edge of the lower hook element 6A, and the free outer edge of the upper hook element 7a. Therefore, the upper the hook element 7a has razoobrazny the notch 7h, possessing the same properties as the notch 6h in Fig. 10A. Bevel 8C vertical locking element 8 for its motion is shown in Fig. 11a, with the aim of kinematic reversal on facing away from the front surface of the N-side extraction 7h to it by contact with the lower hook element 6A, initiated vertical joining movement, was pressed in a horizontal direction in the recess 7h and has accumulated elastic energy.

When the two hook element 6A, 7a occupy is shown in Fig. 11a locked position, the vertical locking element 8 due to the accumulated elastic energy is automatically again rises in the path M connection and enters the locking recess 6f hook element 7a.

In Fig. 11b shows that in this example, the panel with the upper hook element 7a is rotated upward curve unlock, which results in an unlocked position in which the front surface of the N panels 6, 7 form an angle of less than 180°. In addition, in Fig. 11b shows that the vertical locking element 8 during the movement of the unlock just out of contact with locking surface d of the locking recesses 6f the lower hook element 6A without the need for pushing the vertical locking element 8 and deeper into the recess 7h. Polnotsennie p is the surface 6b, 7b and 6E, 7E hook elements 6A, 7a, serving for horizontal locking of the latter, slide past each other until you come out of contact.

The example of Fig. 12A largely corresponds to the example in Fig. 11a, whereby, however, the blocking effect (vertically) enhanced perpendicular to the plane of the panels, because the outer free edge of the lower hook element 6A has a contact surface 6E, which in the United state in Fig. 12A is in contact with polnotsennoi contact surface on 7th shifted back area of the edge of the upper hook element 7a adjacent panel 7. So at the expense of connecting traffic by type of scissors to bring into contact polnotsennie contact surface 6E, 7E, it is necessary to elastic deformation.

All of the examples in Fig. 4A, 6A, 10A, 12A of the free outer edge of the lower hook element 6A has polnotsennuyu contact surface 6E in contact with the adjacent panel. The degree of undercut in the vertical direction, respectively, is small, so necessary when connecting the movement of the elastic deformation to overcome the undercut is not damaged hook elements 6A, 7a, so that it broke the blocking action of the contact surfaces 6E, 7E.

In Fig. 13a, 13b shows an example of a largely corresponds to the example in Fig. 3a. OEM home button Flex cable is treno only a particular execution of the vertical locking element 8. It is located in the same mounting location on the lower hook element 6A, as shown in Fig. 3A. To lock from the divergence of the panels 6, 7 in their plane, namely perpendicular to the coupled edges, hook elements 6A, 7a provided with interacting odnotrahniki surfaces 6b, 7b. Vertical locking element 8 is zigzag or arcuate protruding pruinose-elastic contact bodies 8d, which provide a locking action in the vertical direction, namely perpendicular to the plane of the panels, due to the fact that they release path M connection for the upper hook element 7a under the action of its return pressure, and after elimination of reciprocal pressure spontaneously move through the accumulated elastic energy, again come in the way of connection and block it. Contact the authorities 8d are located on the offset back area of the edge of the lower hook element 6A. In addition, the vertical locking element 8 has two plug-in section 8E, approximating the plug-in section in Fig. 3A. For them in the lower hook element 6A is provided razoobrazny recesses 6i. Plug sections 8E vertical locking element 8 can be placed in photobrush notches 6i can move them forward and backward. They contribute BP is time to release and re-overlapping paths M connection. On the other hand, plug-in sections 8E can be firmly connected to razoobrazny the slots 6i, for example by press-fit connection with tightness and/or due to glue them in. Favorably, if only one of the plug sections 8E is firmly connected in razoobrazny the notch 6i, and the other plug-in section 8E movable in its razoobrazny the notch 6i.

Between each contact body 8d and the edge, which is vertical locking element 8, there is a free space 8f. To nominate speakers contact the authorities 8d from the path M of the connection of the upper hook element 7a, they are automatically pushed to the edge of the lower hook element 6A. When this contact bodies 8d projname is elastically deformed and pressed into the free spaces 8f. Due to this recent decline. In the form shown in Fig. 13A locked position, the hook elements 6A, 7a of the contact bodies 8d again pruinose-elastic open and fixed in the corresponding fixing grooves 7i, provided for this purpose on the outer edge of the upper hook element 7a. Behind the contact bodies 8d free space 8f increase again in the blocked state of the two hook elements 6A, 7a.

Here it should be noted that the blocking action to prevent discrepancies panel is th 6, 7 in the direction perpendicular to their plane arises even when the vertical locking element 8 has only one contact body 8d and one plug-in section 8E, as is explained below using Fig. 20A, 20b. In addition, the vertical locking element 8, having two contact body 8d and two free space 8f, can be equipped alternatively, only one plug-in section 8E, so that the lower hook element 6A requires only one patapata notch 6i. In the case of the vertical locking element 8 with two contact bodies 8d and one plug-in section 8E of the latter may be located in the middle between the two free spaces 8f contact bodies 8d.

In Fig. 13b shows how the two linked panels 6, 7 can be separated from each other. Panel 7 with the upper hook element 7a is rotated upward along the curve V unlock in the unlocked position in which the front surface of the N panels 6, 7 form an angle of less than 180°. For the operation of the unlock, as in each of the examples described, it is important that all polnotsennie surface 6b, 7b are in contact with each other to block, were withdrawn from contact in the unlocked position.

In Fig. 14a, 14b depicts an example, mainly corresponding example is shown in Fig. 13A, 13b, and the same vertical locking element 8 is provided in another site, namely in the upper hook element 7a, which is provided for this razoobrazny hollows 7j. The lower hook element 6A is supplied with corresponding locking grooves 6j, which can elastically to enter the contact bodies 8d vertical locking element 8. The functions of other identified reference positions of the signs are the same as in the example of Fig. 13A, to which reference is made. Is depicted in Fig. 14b unlocking occurs in the same manner as in Fig. 13b, by turning the dial 7 up V curve unlock.

In Fig. 15A, 15b shows a combination of the examples of Fig. 13A and 14a. Vertical locking element 8 is located in each of the hook elements 6A, 7a. Both vertical locking element 8 is suitable for fixing to each other. They oppose the separation of the panels 6, 7 in the direction perpendicular to their plane. Unlocking is shown in Fig. 15b and functions in the same way as unlocking described in the examples of Fig. 13b and 14b. Functions indicated by the reference positions of the signs are the same as in the example of Fig. 13A, 13b and 14a, 14b, to which reference is made.

In Fig. 16 in the enlarged view shows a section of the vertical locking element 8, which may knight is used in the examples in Fig. 3A-8b. Vertical locking element 8 has an insertion section 8b, supplied with mounting bodies. Plug-area vertical locking element is inserted in the recess 6C, 7f hook element 6A, 7a. The connection between the plug-in section 8b and the recess 6C, 7f may be based on the press fit or glue. The mounting bodies of the insertion section 8b have a contact surface 8g, which in the United state adjacent to the lateral wall of the recess 6C, 7f. The mounting bodies of the insertion section 8b are located next to each other on the opposite the contact surface 8g-side protruding retaining elements 8h. Between the retaining elements provided 8h intervals 8i. If the plug-in section 8b must be connected to the recess 6C, 7f, by press fit, they must be made of less width than the insertion section 8b. As a result, in places of contact, where the retaining elements 8h are in contact with the recess 6C, 7f, there is a high unit pressure and elastic deformation occurs in the contact between the materials. Thus, the vertical locking element 8 is located in hook elements 6A, 7a without falling out. If the press fit is undesirable, the recess may be made of greater width than the width of the insertion section 8b. The village is one nonetheless may be connected to the recess 6C, 7f glue. While it is preferable that the intervals between 8i restraining elements 8h insertion section 8b can form a reservoir for glue.

To the contact surfaces 8g plug section 8b at its free end is adjacent the beveled surface 8j. It serves to ensure that during installation you make it easier to place the insertion section 8b in the recess 6C, 7f. Thanks to the beveled surface 8j free end surface of the insertion section 8b has a significantly smaller width than the width of the openings of the recesses 6C, 7f, so the plug-in section 8b easily enters the hole recesses 6C, 7f. On the opposite beveled surface 8j end to the contact surface 8g adjacent protruding sideways shoulder 8k. Incapable of mounting shoulder 8k is in contact with the ground over a wide area of the recess 6C, 7f. In the example of Fig. 16 shoulder 8k limits the insertion depth vertical locking element 8 in the recess 6C, 7f. On the free end of the insertion section 8b, on the contrary, is provided by the distance to the bottom of the recess 6C, 7f.

The shoulder 8k adjacent bearing surface 8m, oriented approximately parallel to the contact surface 8g. Bearing surface 8m in this example, is in contact with the side wall of a wider area of the recess 6C, 7f. It serves for the perception of effort entered in spaced obliquely pruinose-elastic is the locking lug 8A, which is on the opposite plug-in section 8b of the end-section of the vertical locking element 8. The free end of the locking tongue 8A faces the side vertical locking element 8, on which the retaining elements 8h plug-in section 8b. The locking lug 8A has an external 8n and 8p internal surface. Between the support surface 8m and the outer surface of 8n is formed angle greater than 90° and less than 180°. On the inner surface 8p at the base of the locking tab 8A performed deepening 8r. It reduces the cross-section of the base of the locking tab 8A, and thus, it pruinose-elastic bending in the direction of the insertion section 8b.

Vertical locking element 8 is made in the form of extruded parts and processed in the form of molded products. So cut the pieces to equip provided with a hook element edge of the vertical locking element 8 corresponding length. Optimal vertical locking element 8 is made slightly shorter than the edge of the corresponding panel, in order to avoid his departure.

In Fig. 17 shows an example of a vertical locking element 8, which can be used for hook elements 6A, 7a in Fig. 9a-12b. He made the type of flexible flat spring which, being located in the recess 6h, 7h to cobrasnake element 6A, 7a, has a maximum stroke f. On one side of the vertical locking element 8 is made bevel 8C for movement, which in this example runs along part of its length L. the cross-Section vertical locking element 8 is shown in Fig. 18. It also shows the shape of the bevel 8C. He serves as a contact surface for the hook element 6A, 7a, from which direction perpendicular to the surface of the vertical locking element 8 presses on the bevel 8C and through vertical joining movement of the movable hook element 6A, 7a causes the horizontal pruinose elastic movement of the vertical locking element 8. It accumulates elastic energy when it moves in the direction of the bottom of the recess 6h, 7h.

Another vertical locking element shown in Fig. 19. In this example, it can be used to hook elements 6A, 7a in Fig. 13A-15b. We are talking about the vertical locking element 8, having two contact body 8d. They are located in a plane perpendicular to the plane of the panels and removed sideways from the edge of the hook element 6A, 7a. Contact the authorities 8d have pruinose-elastic properties. Vertical locking element 8 is located in the recess 6i, 7j hook element 6A, 7a. Side of the contact bodies 8d addressed in the state Assembly to the edge of the panel, Opera is implemented in separate locations on the contact surface of the edge of the panel. Between the contact bodies 8d and the contact surface provided by available space 8f. They form the course f the springs that contact the authorities 8d can be pushed from its protruding position to the contact surfaces on the edges of the panel.

Vertical locking element 8 in Fig. 19 made in the form of extruded parts and processed in the form of molded products. So cut the pieces to equip provided with a hook element edge of the vertical locking element 8 corresponding length. Optimal vertical locking element 8 is made slightly shorter than the edge of the corresponding panel, in order to avoid his departure.

In Fig. 20A, 20b shows an example with the panels 6, 7, which in General correspond to the panels in the example of Fig. 6a, 6b. Differently executed only vertical locking element 8 and the recess 6i provided in the lower hook element 6A to accommodate insertion of section 8E vertical locking element 8.

Special vertical locking element 8 is located in the same installation location in the lower hook element 6A, and vertical locking element 8 in Fig. 6A. To lock from the divergence of the panels 6, 7 in their plane, namely perpendicular to the coupled edges, hook elements 6A, 7a provided odnotrahniki surfaces 6, 6e, which interact with odnotrahniki surfaces 7b, 7e. Vertical locking element 8 has a protruding pruinose-elastic contact body 8d, which provides a locking action in the vertical direction, namely perpendicular to the plane of the panels, due to the fact that clears the way M connection for the upper hook element 7a under the action of its return pressure, and after elimination of reciprocal pressure spontaneously moves at the expense of the accumulated elastic energy, and again enters the path M connection, blocking it.

Vertical locking element 8 becomes their pruinose-elastic properties due to the two spring bodies 8n distance laterally from the insertion site. Springy bodies 8n rely on the edge of the lower hook element 6A. They absorb elastic energy when the contact body 8d is pressed into its recess 6i. Between springy bodies 8n and the edge of the lower hook element 6A is provided free space 8f, which provide space for elastic deformation of the spring bodies 8n.

Vertical locking element 8 is located on the offset back area of the edge of the lower hook element 6A. In addition, the vertical locking element 8 has an insertion section 8E, approximately corresponding plug-in block h is Fig. 6A. For push-in section 8E in the lower hook element 6A is provided by the mentioned patapata notch 6i. Plug-in section 8E can be placed in it can move forward and backward. He contributes to the interim release and re-overlapping paths M connection. On the other hand, plug-in section 8E can be firmly connected with razoobrazny the notch 6i, for example by press-fit connection with an interference fit and/or by putting in it the glue.

In Fig. 20b shows the disassembly shown in the form of fragments of the panels 6, 7 by means of hook elements 6A, 7a. As the panel 7 in Fig. 6b, here the panel 7 also turns up curves V1, V2 unlock.

All kinds of vertical locking element 8 shown in Fig. 3A-20b, can be swapped. This implies that a particular vertical locking element 8, is depicted in one of Fig. 3A-20b, can be replaced with any other vertical locking element 8. In some cases, this necessitates the coordination of the execution of the edges of the respective hook element 6A, 7a on the area in contact with the vertical locking element 8, with the data used vertical locking element 8. Under certain circumstances, to provide a kinematic function, vertically to record the surrounding element 8 must be located also mirror-inverted. So, for example, shown in Fig. 9a vertical locking element 8 can be used to replace the vertical locking element of Fig. 7a. For this purpose a bevel 8s should be facing away from the front surface of the N panel 7 to provide, therefore, a kinematic reversal, and the desired operation of the automatic unlock.
