SUBSTANCE: floor coating comprises many separate panels laid with jointing between each other, which are equipped with fixing planks on head sides and on longitudinal sides. There are slots provided in head sides. Slots of two head sides jointing with each other match and form a fixing channel for placement of an end key, which is previously mounted into one of slots. The end key protrudes beyond the end of the slot facing the longitudinal side of the separate panel, and by means of displacement of the protruding end of the end key inside the slot it may partially move from the slot into the appropriate slot of the adjacent panel. In a slot holding an end key there is at least one groove, in which a leading surface is arranged, and where the end key ledge enters to be engaged. The end key has a wavy shape, sides of which face the decorative side and the lower side of panels at least one non-wavy area arranged at the distance from ends of the end key between two wavy areas.

The invention concerns a floor covering with signs that are listed in the restrictive part of claim 1 of the claims.
According to WO 2008/017301 A2 to the prior art include floor coverings, which are composed of many stacked with the connection between the individual panels, which on their head sides and on its longitudinal sides provided with locking strips in assembled position located in the floor near individual panels are engaged with each other. With this in head sides provided by the grooves, and the grooves of the two abutting each other head sides coincide and form a locking channel for placement of the end pins. End key pre-mounted in one of the grooves and advocates facing the longitudinal side individual panels the end of the groove. At the same time end key in a pre-assembled condition, fully enclosed inside the groove and can by moving the protruding end of the front dowels inside of the groove, at least partially move out of the groove in the corresponding groove of the next individual panels. A significant advantage of this consists of separate panels of flooring is that there is no additional clogging or retraction end keys in the locking channel. So is the process of sadhane is performed at the factory.
While running on the factory mechanized insertion of the mechanical key is not a problem, the installation, you must ensure that the end key, on the one hand, were not easily moved, but on the other hand, were not allowed to move in a vertical direction adjacent to each other leading parties, which would result in undesirable vertical displacement on the visible side, in particular when individual panels are load near the head of the parties. Therefore, the front dowels should, on the one hand, to be the most durable, but on the other hand, can be easily moved.
The basis of the invention is to specify consisting of separate panels, floor covering, which is applied located on the head side of the floating pins that despite the fact that they can easily be displaced, when the load on the floor also minimize the vertical displacement in the area of head sides, so that the technique of using floor covering is improved.
This task is solved by the characteristics of claim 1 of the claims.
Important in the invention of flooring is that the end plug attached to the waviness very special way. Provided that the front dowels, less than the least one navanita region, which is located at a distance from the ends of the front dowels between the two wavy areas.
Although WO 2008/017301 A2-known application of the wavy end of the dowels, but WO 2008/017301 A2 describes a continuous wave. Consequently, the end plug along its entire length is relatively elastic, that is, moves easily, however springy even under load, that may cause undesired vertical displacement, when the adjacent panels are experiencing uneven load. To solve the problem, now there is at least one navanita and therefore less elastic region, and in addition, provides an elastic wavy region. It is important that at least one navanita region is located at a distance from the ends of the front dowels, i.e. preferably in the Central region, to strengthen the Central region of the head part.
Preferably navanita region is made integrally, so that it fits into the groove. Therefore, when the displacement of the friction in this nevolnichiy area is the greatest. It is therefore advisable to limit the size nevolnichiy area to end the key remained easily movable. It turned out that the aim should be to relationship between wavy and nevolnichiy areas, which shall be at least 21. In this regard, the key can move easily, but at the same time ensures that the head side even under load accurately matched.
In addition, it is considered preferable if at least one end of the front dowels made navanita region.
End key should be nevolnichih areas of thickness, even when the load on an individual pane is greater than the thickness of the wavy areas. This can be implemented through different thicknesses wavy and nevolnichih areas. In an unloaded state, the thickness of the wavy and nevolnichiy areas may be the same, which is possible due to the different amplitude or respectively corresponding to the height of the wave crests. When this depression waves should be placed directly opposite the crests of the waves, because only then are provided with elastic properties wavy areas.
Other benefits can be achieved through the orientation of the wave crests and troughs of the waves. In the invention, the recess in the groove forms a platform that receives the protrusion of the end pins. Depending on the rise of the protrusion and the recess is obtained resulting from lateral displacement and longitudinal displacement direction, which is determined by the orientation of the contact area of the protrusion and the recess. In any case, it turns out direction is viginia, diagonal to the head-end-side individual panels. The force of sliding friction between the end plug and the walls of the groove can be reduced to a minimum, if the crests of the waves respectively corresponding to the top of the crest of a wave, oriented as the resulting direction of movement of the end pins. The crests and troughs of the waves due to this seem to be obliquely. Then they have a somewhat greater length than if they were at right angles to the longitudinal axis of the front dowels, however, compared with the advantages that arise as a result of less resistance to sliding friction, it can be neglected.
In the result, due to the inclined position of the crests and troughs of the waves is achieved that the end key at offset comes into contact with lower surface areas of the grooves and therefore much easier can be moved. This reduction forces of sliding friction can be used to choose the tolerances between the groove and the spring shorter, i.e. to perform the end key several more thick. This makes it tighter installed in assembled position in the slots that leads to that end key even when the load is not perekalivatsja inside the grooves, so that the visible side individual panels is not undesirable movement. The effects of environmental improvement is moved without difficulty styling.
Moving in the longitudinal direction of the head groove preferably less than 10 mm, and in the ideal case is the same size as the width located on the longitudinal side of the key individual panels, ie, for example, from 1.5 to 4 mm, While protruding from the head groove plot to manipulate the mechanical coupling must not protrude beyond the extreme outer edge individual panels, i.e. in particular for the lower retaining bar. In the locked position the end key is completely inside the head of a groove.
Under the head side in the sense of the invention should be understood end-side individual panels. Headache side, usually a shorter side individual panels, even while the square of the individual panels have a head side end key, and the longitudinal side.
The surface of crowding is a contour in the form of notches in the slot. Very recess provided in the base of the groove. The recess may be, in particular, is made by cutting so that the notch had the outline of a circular segment. This circular segment can be in their transition areas also scroogle towards the base of the groove so that we obtain a somewhat sinusoidal shape of the notches. This is not least due to the technologically as during processing otdeleniye panel move parallel to the saw blade which is used to perform the extraction. If this movement is not completely in sync, this leads to a blurring of boundaries in the field edges and along with the rounded transitions. A decisive feature of the surface of crowding, namely that it is contoured, counter to cause lateral displacement of the end key during its longitudinal movement.
It is theoretically possible that the seizure was a pocket rectangular configuration, which is finger cutter, or just a hole in the base of the groove, the surface of the crowding of the holes is limited by the edge of the hole so that the jutting in this case, the hole lug only comes in point contact with the surface of crowding.
The idea of the invention can be applied to all systems of the floor, which the upper floor is located on the grounds, as, for example, coatings made from natural wood, laminate, applied as a top coating the substrate with a surface with paint, linoleum, cork on the base in the form of tiles, etc. Covering layer can, in particular, consist of decorative paper with a top layer that defines an external view of a single panel. Thus, the floor can be a parquet floor, finished parquet is ol, solid wood flooring or floor laminate.
Preferred enhancements to implement the ideas of the invention are subject of the dependent claims, the content of which is explained in more detail using the embodiments depicted in the schematic drawings.

Figure 4 is a top view of the head of a single panel, which is shown partially in cross section, with spring and
5 is a head-side individual panels in the viewing direction according to the arrow V shown in Figure 4 (type head side end).
Figure 1 shows a floor covering consisting of a set of stacked connection between a separate rectangular panels 1. A separate panel 1, respectively, at their head sides 2, 3 and at its longitudinal sides 4, 5 provided with locking straps. The locking strips are in assembled position located in the floor near the panels into engagement with each other.
Retainer strap 6, 7 on the sides of the head 2 or 3, respectively, a separate paragraph is Neli 1 seen in figure 2. Figure 2 shows a vertical section of the head region of a joint between two separate panels, so you can see the connection on the head sides 2, 3. Not pictured locking flanges on the longitudinal sides of a single panel 1 may have a different configuration than the locking strap 6, 7.
A separate panel 1 consists of a carrier layer 8 is made of a fibrous material, usually from a high or sredneoblastnoy fibrous plates, while supporting layer 8 are located on the upper side of the covering layer 9 on the lower side of the compensating layer 10. The covering layer 9 may consist of decorative paper with a top layer that defines the appearance of a separate panel 1. The so-called top layer or protective layer is a treated with a special resin working layer, which imparts a separate panel 1 high surface wear resistance. Compensating layer 10 on the lower side of the base layer 8 serves for stability and exclusion of moisture.
Each individual panel 1 has one locking strip 6 (1 retainer strap) with head side 2 (1-I head side) and one locking strap 7 (2nd fixing bracket) with the opposite head side 3 (2-I head side). In the 1st retainer strap has an open bottom of the 1st connecting channel 11, and t is the train upward end of the 1st connecting protrusion 12. 2-I clamping strap 7 on the opposite of the 2nd head side 3 separate panel 1 is from the floor and stands relative to the base layer 8. The bottom side 13 of 2nd retaining strap 7 is held in the plane of the bottom side 14 separate panel 1. The 2nd retainer strap 7 has an open up 2nd connecting channel 15 and upward end of the 2nd connecting the projection 16.
When in the engagement of the 1st retainer strap 6 and 2nd fixing strap 7 1 connecting protrusion 12 is in the 2nd connecting channel 15, and the 2nd connection tab 16 is in the 1st connecting channel 11. When this contact facing each other and held with an inclination in the same direction side surfaces 17, 18 of 1st connective protrusion 12 and the 2nd connecting projection 16. Thus, there is a point of pressure on the side surfaces 17, 18, which causes the force that creates the attraction of two separate panels 1 to each other in the area of the covering layer 9, so that the transition in the area of intersection of two separate panels 1 to cover the seam 9 is a kind of seamless.
On the head sides 2, 3 individual panels 1 made grooves 19, 20, which pass through the entire length of the head sides 2, 3. As can be seen in figure 2, the grooves 19, 20 abutting each other head sides meet each other and form locking to the cash 21. In this retaining channel 21 is pushed depicted by shading the end of the key 22. The grooves 19, 20 in the head sides 2, 3 are provided on the locking bars 6, 7 in the bearing layer 8.
Figure 3 shows the image in perspective in the direction of the eyes on the head side 2 separate panel 1. From this image it is necessary that the end key 22 in a pre-assembled position is located wholly within the groove 20 and, in particular, advocates located on the head side opening 23 of the groove. However, the end plug 22 with its end 24 in the region of the longitudinal side 5 is issued from the groove 20. Figure 3 only as an example, is depicted as a mechanical key 22 is located in the groove 20. The principle of operation and also the possible embodiments of the mechanical key is explained below using Figure 4 and 5.
Figure 4 shows one of the variants of the end tabs 22, which again is in the slot 20 separate panels 1 and again when you commit two separate panels shifted in the direction of the arrow P and protrudes out of the groove 20 in the direction of the arrow P1. The sum of the arrows P and P1 is obtained direction V of the movement. The angle W is preferably from 25° to 30° relative to the longitudinal axis L of the end tabs 22, which coincides with the direction of the arrow P.
The resulting direction V of the movement determines the orientation of the ridges 26 in the LF and depressions 27 of the waves in the undulating areas 28 and 29 of the end tabs 22. Between wavy areas 28 and 29 is approximately in the center of the front dowels 22 navanita region 30. Another navanita region 31 is located on the end 24 of the mechanical key 22.
The crests 26 of the waves and troughs 27 waves are parallel to the direction V of the movement.
Figure 4 the letter A indicated the shortest distance between two adjacent crests 26 of the waves, and B is the width of the front dowels 22. It is seen that A is less than B.
The direction V of the movement of the mechanical key 22 is obtained by two protrusions 43, 44, which are towards the base of the groove 20. The first protrusion 43 is in the transition region from the Central to the left in the picture plane of the third front dowels 22. The protrusion 43 has a trapezoidal configuration and projects into the recess 45, which has the configuration of a circular segment. Trapezoidal shape or adaptation of the protrusion 43 to the length of the notches provides the inability unwanted slippage of the end pins in one direction or another and serves to Orient the location inside of the groove 20. The short side of the trapezoid, which is first introduced into the groove 20, is preferably provided with a chamfer top and bottom sides to form bevel conducive to the input, which facilitates the insertion of the mechanical key 22 into the groove 20.
The recess 45 is made, for example, using disk blade, which was introduced in the AZ 20. The ledge 43 corresponds to the depth of the recess 45 so that the end plug 22 in the unfixed state is adjacent to the base of the groove. While its front end 24 does not advocate a separate panel 1. This front end is the second protrusion 44, which takes place in located on the longitudinal side of the connecting channel 35. This ledge 44 runs at a 90° angle in the transition region located between the longitudinal sides of the connecting channel 35 and located on the face side of the groove 20. As the motion path is small, the second protrusion 44 is made shorter or not is so far in the direction of the connecting channel 35 as the projection 43 provided for this purpose in the recess 45. The geometry of the protrusions 43, 44 may be mutually agreed upon so that it was possible parallel movement of the mechanical key 22.
Protruding end 24 of the end tabs 22 can also be specified in the direction have already been laid individual panels 1, i.e. in the opposite direction. In this case, the end 24 is adjudged to be in engagement with the already laid separate panels 1 so that the new number of individual panels 1 is fixed already laid separate panels 1. This is an advantage when laying the last or extreme range at which it is advisable to change the shift direction to the opposite, i.e. to shift (the opposite of the one direction shift) or, respectively, to displace the ends 24 of the end tabs 22 from the other end part of the groove 20 in the corresponding groove 19 adjacent a separate panel 1.
Figure 4 and 5 shows that in the region of the protrusion 43 is distributed multiple there of the clamping pins. The locking pins 46 are small projections on the top side or bottom side of the ledge 43 and serve to hold the end key 22 shown clamped in position.
Figure 5 shows the mechanical key 22 on the end. From this perspective it is clear that the mechanical key 22 in some areas in the direction of the upper and lower sides of the groove 20 is made wavy, so that the contact surface of the mechanical key 22 is reduced due to the groove 20, to reduce friction. Moreover, it is seen that the locking pins 46 are offset relative to each other as the upper side and the lower side end tabs 22 and hold it inside of the groove 20. In addition, it is clear that drawn by the dashed line protrusion 43 has a thickness that is less than the thickness D of the main part of the mechanical key 22 to the friction between the guide 43 and the surface of crowding inside the notches 45 as small as possible. It is also seen that the wall thickness in the undulating areas is not equal to the thickness of the mechanical key 22. In the undulating areas of thickness D is less than nevolnichih areas.
