The technical field to which the invention relates.

The present invention relates, in General, to the panels for cladding surfaces. More specifically, the invention relates to systems floating floor covering and, in particular, panels, commonly known as boards and plates for laying such systems floor coverings.

Prerequisites for creating inventions

The popularity of "floating" systems the flooring has increased significantly in recent years. Unlike systems flooring, laying which is made with nails and glue and is so complex that it requires the participation of specialists, "floating" system styling are of particular advantage is the ease of installation (installed on already existing carpet, ceramic, vinyl floor or directly on the stone floor).

As you know, planks for flooring are usually on the sides of the connecting elements in the form of tongue and groove, which are used for mutual coupling (locking connection) of two adjacent boards during installation of the flooring system.

Among the different existing systems, which provide a locking connection of floor boards and used the "floating" installation of flooring, the greatest demand among the consumers use of the so-called "angular lock the first connection, which are so dominant that soon, no doubt, will supersede all other systems. In these systems, the angular interlocking connection of the two floor boards are connected to each other by inserting the assembled boards at a certain angle (usually 45°) to the already established Board and perform a rotary movement around an axis approximately coincident with the joined edges of the upper parts of the boards to get a joint.

Such a system is described, for example, in U.S. patent US 4426820, issued in the name of Heinz Terrace. Floor boards are rectangular in shape and designed for docking with the help of interlock their longitudinal edges. For this, one edge has a first coupling element includes a groove and the other of the second connecting element, which includes the tongue, which is designed for engagement with the first connecting element adjacent floor boards. Mechanical means of fastening are part of the above-mentioned connecting elements, so that when the flooring covering boards do not come apart at the seams in the direction perpendicular to the above-mentioned edges and parallel to the plane of the flooring. In accordance with the profile of the compounds described in U.S. patent US 4426820, the groove of the first coupling element is formed by the upper ledge and the lower ledge. Lower high the UE extends beyond the upper lip and includes the speaker becoming jammed item. The second coupling element includes, in addition to the tongue, which is inserted into the groove of the first coupling element becoming jammed channel that connects to the speakers becoming jammed element in order to deprive the Board of mobility in the transverse direction.

Manufacturers have since been proposed a variety of improvements, the most useful of which is recognized as well-known so-called "click-system". "Click-system" describes a partial immobilization of the boards relative to each other after installation, ensuring a tight mutual coupling by preventing their movement in the direction of disengagement: in order to disconnect the newly attached Board, you need to put some effort. Such partial consolidation has two advantages:

- ease of installation. This is because before laying the boards in the last row with their long sides already laid, it is convenient to attach them to each other with their short sides (which have profiles similar to the profiles on the long sides) and fix them with the help of props (wedges). "Click effect"acting on the short side, allows you to connect together a series of boards, to reduce the number of used props and thereby facilitates the insertion of a number of boards.

- the belief that until the key is perfectly bonded to each other, as "click effect" ensures a strong connection. Thus, this effect acts to some extent as an indicator of build quality. This feature is of great importance, mainly in the case of laminated products on the basis of MDF (wood stove medium density) or HDF (wood stove high density) of small thickness (for example, 6 mm), the grooves in which shallow, and the protruding parts are fragile.

This effect is partially Immobilise is achieved due to friction, more specifically, through the use of the elastic properties of the material at the end of making a rotary movement during installation.

This "click-system" is described, for example, in European patent EP 1026341 B1, owned by the company UNILIN. In this system, the connection elements are provided with means which, once inserted into each other in the bond of two floor boards, operate at each other with a force of mutual tension, which pulls the boards with each other. This effect is achieved due to the special configuration becoming jammed channel and becoming jammed ledge, which in the assembled condition caused by elastic deformation of the lower protrusion of the first connecting element and create the desired effect voltage.

Thus, in known systems "click effect" is usually cut what litecom use internal elastic composite material boards. In addition, the forces acting during the "click effect", will create a more or less stress on the Bulletin Board at the point where it essentially the most delicate.

Finally, it should be noted, and this is evident from the interest, which is called by the system that this "click effect" the more valuable, the more he pronounced.

In this regard, it is easy to understand that, in the case of products of small thickness, for example, type HDF, is difficult to measure the strength of the material intensity "click effect". This is because the Board of such material may have a thickness less than one millimeter.

The purpose of the invention

In connection with the above there is a need for boards to floor coverings with an angular locking connection using "click effect", which would ensure a strong connection boards in the process of laying, but with no danger of damage to the boards for flooring.

General description of the invention

In accordance with the present invention is achieved through the panel stated in paragraph 1 of the claims.

The panel in accordance with the present invention has connecting elements for angular locking connection, mostly, without any elastic deformation, which are similar in this aspect of the element is, usually used in the system, referred to as Terbrack. In accordance with one important aspect of the present invention, at least one of the connecting elements is equipped with a reusable adhesive for bonding together two similar panels connected by appropriate connecting elements. Thus, there is a corner lock connection with "click effect", mostly without any elastic deformation of the connecting elements and panels, and you can assemble/disassemble panel, without compromising their integrity.

The term reusable adhesive usually denotes an adhesive material having an adhesive force, known as stickiness or tackiness, which is enough for immediate adhesion under load. Such adhesives allow you to repeatedly assemble and disassemble the connection, as a rule, without reducing the stickiness. Reusable adhesives usually have less stickiness than usual adhesives, and adhesion strength does not increase after contact.

When performing interlocking connection of the reusable adhesive that provides you with quick attach panels to each other, that is, immobilizes them relative to each other. The fact that the panel is bonded, is an indicator of obtaining nucleases the locking connection; piling can be made without fear of what the panel will go. When there is desire to disassemble the laid panel, just enough to overcome the adhesion force of the adhesive. In practice, the resistance felt when dividing panels, similar to the one in "click-system" due to the elastic deformation.

The present invention accordingly relates to panels for surface blending, the connecting elements which are intended to facilitate the use of systems similar to the famous "click-system". However, the panel in accordance with the present invention has a "click-system", based on the chemical properties, in contrast to the known "click-system"that uses mechanical properties, and is not based on elastic deformation of the connecting elements and the clutch (the immobilization of the respective connecting elements relative to each other) due to the physico-chemical properties of the joined materials.

In accordance with a preferential option for the implementation of the first coupling element includes an upper ledge and a lower ledge, which form the groove bottom ledge extends beyond the upper lip. In addition, the mechanical locking elements include:

raised up from the lower ledge becoming jammed item, thus becoming jammed ELEH the UNT has first becoming jammed surface; and

second becoming jammed the surface of the second connecting element, which connects with the first becoming jammed surface similar panel to prevent displacement in the direction perpendicular to the edges and parallel to the plane of installation.

In this implementation becoming jammed item mainly located on the lower ledge outside above the top of the protrusion in the direction perpendicular to the edge. After this, the second becoming jammed surface is becoming jammed channel on the second connecting element for sheet piling.

First becoming jammed the surface is mostly flat, may be becoming jammed angle from 35° to 70 ° relative to horizontal. The greater the angle, the more effective transverse immobilization.

Usually in the corner of the castle connections connecting elements are arranged so that the tongue of the first panel may be inserted at a certain angle in the groove of the second panel, and the second stopper panel can be inserted becoming jammed in the channel of the first panel relative rotary movement of these two panels about an axis of rotation passing through the upper ends of the joined edges. Reusable adhesive is applied mainly on the surface of the connecting elements that are in contact only under load at the end of the swivel is viginia in the process of laying, providing instant bond boards with each other and not preventing locking connection.

In order to separate two bonded panel, it is necessary to overcome the adhesion force of reusable adhesive. In this document the term "date of separation" means the torque that must be generated to perform a rotary movement of the pad in the direction of separation. Mainly, such a separation is of the order of from 3 to 9 N·m/m, preferably about 6 N·m/m These values have the same order, which is similar to values observed in the mechanical "click-system".

"Click effect" panels in accordance with the present invention can be adjusted in various ways. In particular, you can modify the following parameters: the stickiness of the adhesive; geometry/profile connecting elements; form adhesive pads; number and location of adhesive pads.

Stickiness is a function of the selected reusable adhesive (glue). To obtain a given moment of separation are typically used reusable adhesives with a given stickiness, the value of which ranges from 0.05 to 0.30 N/mm2most preferably, the value of the order of 0.15 N/mm2. Of course, that stickiness refers to the stickiness of the adhesive with respect to the panels, with edinaman with an adhesive in the process of laying, instead adhesion force of the adhesive to the surface of the connecting elements, for which it was initially applied.

The selected reusable adhesive exhibits better adhesion to the materials of the panels (usually made of HDF, MDF or wood for the production of floor coverings in use, and subsequently stores the level of stickiness, which will provide partial sticking with the same materials, or other materials based on polymers (stickiness remains always below the adhesion, which was used in the manufacturing process). Reusable adhesive must, without doubt, provide immediate adhesion under load and to provide a large number of operations, Assembly/disassembly. There are many different reusable adhesives, allowing you to make the right choice based on the quality of materials, the desired stickiness, the method of application, etc.

The use of hot melt glue is the most suitable, in particular, because of their ease of use. They are applied in the form of drops on the relevant sections of the connecting elements. It is desirable to use adhesives hot melt (hot melt), which after curing to form drops having a hardness (and clutch), sufficient to prevent the adhesive was transferred to another pan the eh during disassembly.

Preferably, a reusable adhesive was applied to the surface of the connecting elements, which are connected only under load at the end of the locking connection (at the end of the rotary movement in the laying process, providing instant bond boards with each other and not preventing locking connection.

In addition, reusable adhesive may be deposited on the front surface of the connecting elements, which are not in contact with each other when the connection of similar panels. Therefore, it becomes possible to apply a drop of glue on the non-functional surface and not performing any adjustment or becoming jammed functions) of connecting elements, such as, for example, located at the level of Assembly gaps.

Such an Assembly gap is usually for becoming jammed element, which includes a surface facing toward becoming jammed channel and having between them a small gap. Typically, these surfaces are not in contact with other surfaces in the process of formation of interlock. The rear surface of the becoming jammed channel, which is different from becoming jammed the second surface, provided mainly by one or more plates of reusable adhesive.

Applying adhesive to the second soedinitel the element, and in particular, becoming jammed in the channel prevents the adhesive from external influences (dust and others), which eliminates the deterioration of its quality.

To ensure the resistance of the lower layer panels, the pad of the reusable adhesive is applied mainly on the lower part of the second coupling element. This overlay can be applied on the upper part of the connecting elements to prevent penetration of moisture through the top surface of the front panel.

As stated above, "click effect" depends on the geometry of the profile. In this regard, it should be noted that the maximum value of the moment of separation is achieved when the adhesive sticks to surfaces becoming jammed item, which lies in the plane passing through the axis of rotation when disconnecting. Usually the surface of the connecting elements, which are coated with a reusable adhesive or that come in contact with the adhesive in the assembled state, are made mostly flat.

It should be noted that the adhesive pads mainly applied directly to the material of the panel, for example, from HDF or MDF, and that these pads [hereinafter in this paragraph the text is missing - approx. the pens.]

It should also be noted that the surface of the connecting elements, which account which can be carried on with adhesive pad, can be made of a material different from other connecting elements. These surfaces can be coated, for example, a polymer. This prevents the accumulation of material of the panel itself on the adhesive during disassembly.

The panel in accordance with the present invention was developed in particular for floor coverings. She may have a traditional shape (rectangle or square) boards for flooring. Traditionally, the first coupling element is located on one pair of short and long sides, and the second coupling element is on a different pair of short and long sides. Pads reusable adhesive are mainly on the coupling elements of the short and long sides.

Depending on the particular application form panels and the number of edges can be different (e.g. in the form of a polygon), and connecting elements are placed accordingly.

The panel in accordance with the present invention can be fabricated directly on traditional technologies, for example, from solid wood, laminated or multilayer material. Reusable hot-melt adhesive can be applied in a simple way, for example, using a gun in a pre-defined point on the coupling elements of immediately the donkey, as the latter have a mechanical processing.

However, the panel in accordance with the present invention can be used for surface covering not only the floors but the walls or ceilings. Such panels can be made of various materials depending on the destination.

In connection with the foregoing it should be clear that the panel in accordance with the present invention allows to obtain a "click effect" even when using such materials, which, unlike wood, HDF or particle Board, does not have elasticity. For such materials, which for certain applications may be a serious competition for HDF include, for example, fibrous cement or some highly filled polymers, which have undergone mechanical treatment (for corner lock profile), but it does not have elasticity.

For many applications in accordance with the present invention, the panel may have a multilayer structure is usually of the following type: top layer/base layer/support (if necessary). The upper layer of panels for floor coverings can be made of wood, which is glued to the support layer, or impregnated with melamine decorative paper (imitating wood or other materials, such as stone, ceramics etc). The support layer can be the t to be made from pressure-treated wood (MDF, HDF, particle Board, or wood shingles. Depending on the field of application of the top layer can be a ceramic or polymeric material. In addition, as mentioned previously, the substrate may be made of fiber cement, polymer or other material that is machinable.

Detailed description of preferred embodiments

Figure 1 shows a view in the context of preferential embodiments of the panel 10 ACC is accordance with the present invention. In this embodiment, the panel 10 is a panel for flooring. This panel, known as the Board or plate has a generally rectangular shape and generally includes an upper face layer 12 opposite to the bottom layer 14, forming the basis for flooring in the collection, along with two opposite edges 16 and 18, respectively, with the connecting elements 20 and 22 for connection with other similar panels. The short sides (ends) also have similar connecting elements.

The first coupling element 20 includes a groove 24 and the second connecting element 22 has a tongue 26. The traditional purpose of these connecting elements 20 and 22 is in the formation of the joint at the connection of the panel 10 with the other panels of the same type.

The groove 24 of the first coupling element is formed by the upper ledge 28 and the lower projection 30 which extends over the upper ledge 28 in the direction perpendicular to the edge 16.

Mechanical becoming jammed elements enclosed in the connecting elements 20 and 22 so that when the panel 10 is combined with another similar panel in the plane of installation, these becoming jammed elements to prevent displacement of the panels relative to each other in the direction perpendicular to the edges 16, 18 and parallel to the plane of installation. In the present embodiment, Zack is inuaysha elements include becoming jammed element or stopper 32, which stands up from the bottom of the ledge 30 of the above stopper 32 defines first becoming jammed surface 34.

Becoming jammed elements, in addition, include becoming jammed channel 36 in the second connecting element 22, and the channel includes a second becoming jammed surface 38. As the tongue 26 and groove 24, the stopper 32 and the channel 36 mainly extend along the entire length of the edges.

As shown in the drawing, the stopper 32 is located in the upper part of the lower ledge 30, speaking for the upper ledge 28 and, therefore, outside of the groove 24. The channel 36, on the other hand, is facing down and is located outside of the groove 26. The stopper 30 (must be the stopper 32 and the channel 36 is arranged so that when the connection (Figure 3) the first and the second becoming jammed surfaces 34 and 36 (must be 38) form a joint, which immobilizes the United panel in the transverse direction and in the direction parallel to the plane of installation. To ensure the effective jamming two becoming jammed planar surface and are primarily based in the same plane which forms an angle α (called the angle of wedging) with the plane of laying (the bottom surface 14 of the panel 10). This angle α has a value of the order of 35-70°.

The connecting elements serve for the formation of interlock. Interlocking connection of the two EN is a logical panels shown in figure 2, where a second similar panel 10' is connected to the panel 10, which lies in the plane of installation. To obtain such a connection panel 10' is placed under a certain angle of inclination and join, introducing her tongue 26' in the groove 24 of the panel 10. The tongue 26' thus gradually enters the groove 24 by means of sliding panels 10' and the inclination angle adjustment up until the top of the edges will not come into contact at the point A. Rotary motion from top to bottom, the axis of which passes through the point A, a second panel 10' is placed in the plane of installation, and thus activated, the stopper 30 (must be the stopper 32) of the first panel 10 in the channel 36' of the second panel 10'.

In accordance with a first important aspect of the present panel 10, the connecting elements are arranged, which is also an advantage, so that in the process of connection and after two full panels are held by their respective connecting elements, which essentially does not cause elastic deformation.

Another important aspect is the presence of one or more plates of a reusable adhesive on the surface, at least one of the connecting elements 20 and 22. It provides immediate adhesion between the edges of two joined panels during installation and prevents their subsequent separation; however, the nature repeat the but used adhesive allows for further separation (disassembly) of the two combined panels by applying a little effort. The panel in accordance with the present invention thanks to this reusable adhesive provides, therefore, a chemical system "click effect", which is also easy to use as well-known systems mechanical "click"effect, and thus does not increase the elastic deformation of the connecting elements.

It is preferable to use such an adhesive (glue) multiple use, which has excellent adhesion with the material forming the Board (usually HDF, MDF or wood) in the process of its production, and subsequently stores the residual force of adhesion (stickiness), sufficient for adhesion to the same materials or other materials polymer type (this residual binding force is always less than the adhesion, which is necessary in the manufacturing process). The glue of this type are sometimes called "glue residual stickiness" or autopause adhesive. There is a wide variety of adhesives reusable, choosing which is traditionally based on the quality of the material, the desired stickiness, the method of application, etc.

In this implementation, the connection is based on the model profile Terbrack described in U.S. patent US 4426820, and which does not result in elastic deformation of the connecting elements. As can be seen from Figure 3, the vertical combination of two of the aamah panels obtained by locking connection "tongue and groove". These are two "functional" zones of contact:

between the groove 26' and the upper ledge 28 within the groove 24;

between the tongue 26 and the lower ledge 30 outside of the groove 24 and opposite the stopper 32.

Immediately after the connection panel are held in the transverse direction becoming jammed elements, which are the two other functional contact surface:

at the level of the upper parts of the edges; and

- becoming jammed between the surfaces 34 and 38.

A more detailed study of the profile of the connecting elements with the help of Figure 3 will allow you to understand what the connection without elastic deformation is different from the connection with the elastic deformation. It is clear that for such a profile condition for interaction without elastic deformation of the connecting elements is the fact that becoming jammed surfaces 34 and 38 are not opposing rotary movement necessary to obtain the angular locking connection. Based on the principle that the axis of pivoting movement during the connection passes through the point A, located at the junction of the upper parts of the edges, it is obvious that the lock by turning movement without resistance can be obtained only when the value of becoming jammed angle α is not greater than the gradient of the tangent to the circle AB at point C. With respect to the dimensions h and l, pakatan the x figure 3, and the angle β between the segment AB and the upper surface of the panel will receive the following value:

α≤180°-arctan(h/l)

For the present embodiments, this condition is satisfied, since the angle α is an edge to a circle of radius AB at point C. At a smaller angle α, the condition also occurs, but is considered to be appropriate highest possible becoming jammed angle α that gives the best cross-sticking.

As was shown above, the profile of the connecting elements of the panel 10 includes a specific set of functional contact zones. Beyond these functional areas is no need to place the connecting elements, which would be in contact. This is, for example, takes place at the rear of the stopper 32, which usually provides an Assembly gap.

In the present embodiment, the implementation of a reusable adhesive is in this functional area of the stopper 32, where it is sprayed as droplets (globules), which mainly extend along the entire length of the edge: a drop of 39 or 39' at the bottom of the channel 38 and drop 40 or 40' in the lower part of the second coupling element 22. Droplet size match (or slightly exceed) the size of the gap between the connecting elements so that at the end of the dock drops 39, 40 turned out to be slightly smeared on the corresponding surface is Rostam connecting elements 20 and 22. A slight bleeding drops improves the adhesion of the adhesive of this type, which usually shows a certain sensitivity to pressure.

It should also be noted that the adhesive pads 39, 39', 40, 40' are mainly on flat surfaces of the channel 36 and the surface of the stopper 32, which is also in contact with the adhesive pads are flat. Furthermore, since the present implementation adhesive pads 39, 39', 40, 40' in the process of laying in direct contact with the material of the stopper 32, a suitable polymer coating can be applied on the stopper 32 so that the particles of the material of the stopper into the drop in the disassembly process (this may be of interest for some materials).

It should be noted that immobilization of the panels by the adhesive occurs without effort, or with minimal effort, ensuring intimate contact of the adhesive material. Physico-chemical properties of the materials in contact, provide immobilization of the panels, and thus do not lead to serious stress that can damage the connecting elements or, more generally, the panel itself. The special nature of reusable adhesives allows you to repeatedly connect and disconnect panel without deterioration of their useful properties.

The desired "click effect" mo is et to be achieved by changing the following parameters: the stickiness of the adhesive; the geometry of the connecting profile; placing drops (drops or beads of adhesive; the shape and size of the droplets of the adhesive and the number of drops. It is clear that an important factor in determining "click effect", is the stickiness relative to the surface to which the adhesive comes into contact with the connection, but not the stickiness, which adhesive is manifested to its source material, which is applied in the manufacturing process of the panel.

Mostly, these parameters play an important role in the disassembly of the panels in accordance with the present invention when receiving "click-effect", which is analogous to the mechanical "click effect". The number of measurements carried out on various known systems mechanical click-effect, showed that the average time that should be attached to separate two adjacent panels, is of the order of 6 N·m at the edge length 1 m (denoted as 6 N·m/m).

The above various parameters affect to create adhesion between the two panels in accordance with the present invention, so it took time (called "the time of disassembly"), which lay between 3 and 9 N·m/m, mainly, about 6 N·m/m, to provide initial rotation when screwing out panel from the plane of the Assembly.

This time of disassembly can be achieved at the expense and the use autopause adhesives with a viscosity between 0.05 and 0.3 N/mm 2mainly about 0.15 N/mm2.

It should be noted, resorting to the comparison that if the panel 10, 10' do not apply reusable adhesive, such disassembly of the panel will be only a function of its weight, as her profile circuit is not deformed during disassembly.

In a variant implementation of the invention shown in Figures 1 to 3, is used autopause glue (reusable adhesive), which is applied in the form of droplets (globules). Mostly it is a melting when heated adhesive (glue), which is applied in a hot state. Depending on the viscosity in the hot condition, such hot melt adhesive can be applied in the form of droplets, films or flattened balls. They are using a gun, which are nozzles of different diameters. It should be noted that the hot-melt adhesive being in a hot state, comes into contact only with the surface to be coated. Next glue hardens (freezes), then its free surface becomes sticky, which creates immediate adhesion, when it is a certain pressure of the stopper 32, but not connects the panel permanently.

Such glue is usually based on polyolefins, polyurethane (PU), ethyl-vinyl-acetate (EVA), polyvinyl acetate (PVAC), polyvinyl-butyral (PVB), etc. In the case of the AE application connecting elements of the HDF, you can use the hot-melt adhesive, known under the brand name INSTAWELD 6615 E (manufactured by the company NATIONAL Starch &Chemical).

You can also use adhesives that can be applied at ambient temperature (for example, acrylic emulsion). Such adhesives can be applied through light contact with the cylinder (roller) of the appropriate size. This type of adhesive requires a larger area of contact.

It should also be noted that the important factor is to apply glue provided the possibility of formation of such adhesive, which would have the property re-use (adhesion) relative to that of the material with which he will come into contact during Assembly. This property can be achieved by adhesives, which are not yet known (not sold) as tipaimukh adhesives, but, nevertheless, covered by the present invention.

As mentioned above, the geometry of the locking profile and the position of drops of glue have an impact on the "click effect", which is perceived by the user. Figure 4 shows a variant implementation of the invention, represented in figure 1-3, in which the profiles of the stopper 132 and becoming jammed channel 136 is modified to enhance the "one-click effect. As you can see, the surface behind the stopper 132 (after becoming jammed surface 134 moves away from the groove 124) is no longer horizontal, but tilted so the m way what takes place in the plane passing through point A - the top United in contact edges.

With this configuration, the stacked surface perpendicular to the direction of efforts at dismantling panels, which gives the opportunity to maximize the time of disassembly required to separate the panels 110 and 110' by turning counterclockwise. Thus, in the presence of a drop (ball), having the same characteristics as that of figure 3, the configuration of Figure 4 gives an opportunity to strengthen "click effect".

To apply these drops occur over a wide range of applications.

Finally, it should be noted multi-layered construction panel 10, which includes (see Figure 1) the top layer 42, the reference layer 44 and the base 46. In this implementation, the top layer 42 of a dense wood (array) is bonded to the support layer. Support layer 44 is made of MDF or HDF. The base 46 is made on the basis of cellulose impregnated with resin.

Depending on the application of the top layer can be a decorative coating impregnated with a melamine laminate or ceramic material. The support layer may be made of fiber cement (fiber cement) filled with resin or other workable material. The base is not always necessary.
