Floor covering

FIELD: construction.

SUBSTANCE: floor covering comprises multiple separate panels laid jointly and having fixing planks on their ends and longitudinal sides, which in the laid position of neighbouring separate panels of the covering are engaged with each other. In the ends there are slots, at the same time slots of two ends that are joined with each other are arranged on a single line and form a fixing channel to receive an end key, which is installed in one of the slots in advance. The end key protrudes from the slot with an end facing the longitudinal side of a separate panel. As the protruding end of the end key moves in the slot, it may partially move from the slot of one panel into the corresponding slot of the neighbouring separate panel. The slot receiving the end key comprises at least one groove, in which the creeping surface is arranged, and where the end key ledge enters with engagement. The end key is corrugated, besides, its corrugated sides face the decorative and lower side of separate panels. Alignment of indents and tops of corrugations must correspond to the direction (V) of end key motion, when the end key moves while pressing the ledge in the groove.

EFFECT: minimised displacement of floor covering by height on a section of ends under load.

The invention relates to gender flooring according to characteristics of the restrictive part of paragraph 1 of the claims.

According to WO 2008/017301 A2 of the same applicant to the prior art include flooring, consisting of many individual panels stacked in contact with each other and having on their ends and longitudinal sides of the locking bars, which in the installation position adjacent decking individual panels are engaged with each other. With the ends provided by the grooves, and the grooves of the two abutting ends correspond with each other and form a locking channel for receiving the end of the dowels. Mechanical key installed in the groove in advance and protrudes out of the groove with the end facing longitudinal side individual panels. At the same time pre-installed end plug is fully seated in the groove and by moving the protruding end of the front dowels into the groove of it, at least partially, can be moved from one groove corresponding to the groove of the next individual panels. A significant advantage of such sexual flooring, consisting of individual panels is the fact that extra driving or pushing the end key in the locking channel disappears. Therefore, this process zataskivanija is carried out at the factory.

While pushing that is zevah keys on the factory machine does not represent any problem, when laying, you must ensure that the end key, on the one hand, easily moved, and on the other, so that they do not allow any displacement of the adjacent ends in the vertical direction, which would lead to undesirable pitch offset from the visible side, in particular, when individual panels are load near the ends. Therefore, the end key, on the one hand must be as stiff as possible, and on the other, it is easy to move.

The basis of the invention is to provide flooring that consists of separate panels which are movable end pins, which can be easily shifted, and minimize the offset of the sex deck height on the plot ends under load, so flooring improved from the point of view of technology use.

This problem is solved by the characteristics of paragraph 1 of the claims.

Significant in sexual flooring according to the invention is that the end key Gavrilovna a very special way. Provided that the orientation of the troughs and peaks of the waves of the wavy areas coincided with the direction of movement of the mechanical key when the end key is moved from the pressing protrusion in the recess.

Although WO 2008/017301 A2 is known to use a wavy end keys, which together partially moved from one p is for in the respective other the peaks and troughs of the waves in WO 2008/017301 A2 there is not moved in the direction of movement of the mechanical key when it is in the internal position is moved from the pressing protrusion in the recess. The recess forms a ramp that receives the protrusion. Depending on picatoste protrusions and recesses of the transverse and longitudinal movements is the resulting movement direction determined by the orientation of the contact area of the protrusion and the recess. In any case, the direction of movement is obtained diagonal relative to the end individual panels.

The force of sliding friction between the end plug and the walls of the groove can be minimized if the tops of the waves, i.e. corresponding to the crest of a wave, oriented so as the resulting direction of movement of the end pins. In the peaks and troughs are kinda at an angle. However, in this case, they become somewhat longer than if they were located at right angles to the longitudinal axis of the front dowels, but compared to the benefits resulting from reducing the resistance of the sliding friction can be neglected.

As a result, the installation of the peaks and troughs of the waves at an angle to achieve that end key while moving in contact with the lower surface of the slots and therefore moves much easier. This decrease is their forces of sliding friction can be used to the tolerances between the groove and the key you can choose smaller, i.e. to the end key, you can do thicker. Due to this, in the embedded position she held in the grooves more tightly, which leads to the fact that the end key in the grooves even under load not perekalivatsja, so that the front side individual panels no disturbing displacement does not occur. The result of the styling is improved without complicating the installation.

The motion path in the longitudinal direction of the end of the groove, preferably less than 10 mm and in the ideal case, equal to the width of the pins with the longitudinal side individual panels, ie, for example, 1.5-4 mm, While the control section end tabs extending from the end of the groove, shall not extend beyond the outermost edge individual panels, i.e. in particular for the lower retaining bar. In a fixed position of the end plug is completely within the end slot.

Under the end in the sense of the invention means the front side individual panels. The end, as a rule, is the shorter side individual panels, and even the square of the individual panels have end with end plug, and the longitudinal side.

The surface of crowding is a notch in the groove. This recess is provided at the bottom of the groove. The notch can be obtained, in particular by cutting, so that the recess has Comte is a circular segment. This circular segment on their transient sites in the direction of the bottom of the groove can also be struglin, so that the notch is obtained in a somewhat sinusoidal. This is, not least, due to the manufacturing technology, because during processing, the individual panels are moved parallel to the cutting cutter, is used to perform the extraction. If this movement is not absolutely synchronously, in the region of the edges are obtained smoothing and, thereby, rounded transitions. A decisive feature of the surface of crowding, namely, that it is contoured counter for providing lateral movement of the end key during its longitudinal movement.

It is theoretically possible that the recess pocket rectangular configuration made bolt cutter, or just drilled a hole in the bottom of the groove and the surface of the crowding of drilled holes is limited by the walls of the hole, so that in this case, the protrusion extending into the borehole, has only point contact with the surface of crowding.

The idea of the invention is applicable to all systems of the sexes, in which the top coating is applied to the substrate, as, for example, coatings made of natural wood, laminate, base with lacquered surfaces as the upper covering, linoleum, cork h is the slab foundations etc. The covering layer, in particular, may consist of decorative paper overlay that defines the external view of a single panel. Thus, in the case of sexual flooring we can talk about the parquet floors, the floors of finished flooring, floors made of natural wood or laminate floors.

Preferred enhancements to implement the ideas of the invention are subject of the dependent claims, the content of which is explained in more detail below in the examples depicted in the schematic drawings, in which

figure 1 depicts a top view of a partial section of a sexual flooring;

figure 2 is a side view of the vertical section of the end section of the joint between two separate panels on the line II-II in figure 1;

figure 3 is a view of a corner section individual panels in perspective, if you look at the end;

figure 5 - end individual panels, when viewed in the direction of arrow V in figure 4.

1 shows a flooring consisting of multiple stacked together rectangular panels 1. Panel 1 are provided on their end faces 2, 3 and at its longitudinal sides 4, 5 of the fixing plate. The locking strap in position adjacent panels in the deck are engaged with each other.

The locking plan and 6, 7 at the ends 2 and 3 separate panels 1 are visible in figure 2. Figure 2 shows a vertical cross section of the end section of the joint between two separate panels 1, so you can see the connection ends 2, 3. Not shown 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 fibrous plates of high or medium density, and the supporting layer 8 is provided on the top side of the covering layer 9, and on the lower side of the stabilizing layer 10. The covering layer 9 may consist of decorative paper overlay that defines the appearance of a floor panel 1.

The so-called overlay, or sealing, forming a useful layer, impregnated with resin, giving a floor panel 1 high surface durability. The stabilizing layer 10 on the lower side of the base layer 8 serves for stability and moisture resistance.

Each individual panel 1 includes a first retaining bar 6 with one (first) end 2 and (II) retaining bar 7 with the second opposite end of 3. The first locking strip 6 contains a first open bottom of the connecting channel 11, and the first downward end of the connecting thickening 12. The second retaining strap 7 with the second FR the opposite end 3 separate panel 1 is located from the bottom and is relative to the base layer 8. The bottom side 13 of the second retaining strap 7 is held in the plane of the bottom side 14 separate panel 1. The second retaining strap 7 contains a second open top of the connecting channel 15, and the second upward end of the connecting thickening 16.

When in the engaged first and second locking bars 6, 7, the first connecting thickening 12 enters the second connecting channel 15 and the second connecting thickening 16 in the first connecting channel 11. While facing each other and arranged with an inclination in one direction side surfaces 17, 18 of the first and second connecting thickenings 12, 16 are in contact with each other. Thus, the side surfaces 17, 18 point appears pressure, creating a force that causes protivostoyanie both individual panels 1 on the land cover layer 9, so that the transition at the site of junction of the two flooring panels 1 on the covering layer 9 is seamless.

The ends 2, 3 of the individual panels 1 are formed the grooves 19, 20, passing through the entire length of the ends 2, 3. As can be seen in figure 2, the grooves 19, 20 abutting each other end faces 2, 3 correspond to each other and form a locking channel 21. In this retaining channel 21 routine indicated by the dotted line end plug 22. The grooves 19, 20 in the ends 2, 3 are provided on the locking bars 6, 7 in a bearing sloe.

Figure 3 shows in perspective the end of the 2 separate panel 1, if you look at it. From this image you can see that the end key 22 in a predetermined position is completely within the groove 20 and, in particular, does not protrude from the inlet 23 of the groove in the end face. However, the end plug 22 with its end 24 to the area of the longitudinal sides 5 protrudes from the groove 20. Figure 3 is only an example, as end key 22 is installed in the groove 20. The principle of action and possible embodiments of the mechanical keys are explained below with reference to figure 4-10.

Figure 4 shows a variant of the end tabs 22, which is also located in the groove 20 separate panels 1 and when you commit two separate panels shifted in the direction of the arrow P and out of the groove in the direction of the arrow P1. On the arrows P and P1 turns the direction V of the movement. The angle W is 25-30° relative to the longitudinal axis L of the end tabs 22, which coincides with the direction of the arrow R.

The resulting direction V of the movement determines the orientation of the peaks 26 and valleys 27 waves of the wavy sections 28 and 29 of the end tabs 22. Between wavy sections 28 and 29 approximately in the middle of the mechanical key 22 is nevolnicy section 30. Another nevolnicy section 31 is at the end 24 of the mechanical key 22.

Peaks 26 and valleys 27 waves are parallel to the direction the V motion.

Figs.4 through And marked the shortest distance between adjacent peaks 26 and through In - width front dowels. It is seen that And less Century

The direction V of the movement of the mechanical key 22 is defined by two projections 43, 44, passing in the direction of the bottom of the groove 20. The first protrusion 43 is located at the transition area from the average at the image plane to the left third of the front dowels 22. The protrusion 43 has a trapezoidal configuration and enters the recess 45 having the configuration of a circular segment. Trapezoidal shape, i.e, the fitting protrusion 43 under the length of the recess ensures that the end key will not slip off involuntarily in a particular direction and serves for longitudinal orientation in the groove 20. The short side of the trapezoid, which first enters the groove 20 preferably has a chamfer in the direction of the upper and lower sides to create the bevel to enter, to facilitate the installation of the mechanical key 22 into the groove 20.

The recess 45 is obtained, for example, by using a disc-shaped cutting tools introduced in the groove 20. The protrusion 43 is designed for the depth of the recess 45 so that the end plug 22 in the uncommitted state adjacent to the bottom of the groove. While its front end 24 does not advocate a separate panel 1. With this front end is the second protrusion 44 extending in the connecting channel 35 on the long side. This ledge 44 moves at an angle of 90° on the site per the passage between the connecting channel 35 with the longitudinal side and the groove 20 from the end. Because the motion path is small, the second protrusion 44 is made shorter, i.e. he does not go as far in the direction of the connecting channel 35, as the protrusion 43 in the notch 45 provided for him. The geometry of the projections 43, 44 can be aligned with each other so that it was possible parallel movement of the mechanical key 22.

Protruding end 24 of the end tabs 22 may be turned in the direction of the already stacked individual panels 1, i.e. in the opposite direction. In this case, the end 24 is engaged with the already stacked separate panels 1, so that a new series of separate panels 1 is fixed already laid separate panels 1. This is an advantage when laying the last or lateral row, when it is advisable to change the direction of shift on the opposite, ie, partial shift, i.e. to move the ends 24 of the end tabs 22 with the other end of one of the groove 20 in the corresponding groove 19 adjacent a separate panel 1 (in the direction opposite to the offset.

In addition, figure 4 and 5 we can see that the section of the protrusion 43 distributed several clamping cleat 46. Clamping studs 46 are small tabs on the top or bottom side of the ledge 43, serving to hold the end key 22 is shown in the clamped position.

Figure 5 shows the end tabs 22 on the front. In this lane is pective clear, that the end key 22 in the direction of the upper and lower sides of the groove 20 seats made wavy, so that the contact surface of the end tabs 22 with the groove 20 to reduce friction reduced. In addition, you can see that the locking studs 46 are displaced relative to each other on upper and lower sides of the end tabs 22 and hold it in the groove 20. In addition, it becomes clear that the protrusion 43, drawn with a dotted line, has a thickness less than the thickness D of the main body of the end tabs 22 so that the friction between the lip 43 and the surface of crowding inside the recess 45 is as small as possible. It is also seen that the distance between the walls of the wavy parts is not equal to the thickness of the mechanical key 22. The wavy sections of thickness D is less than nevolnichih sites.
