The invention in General relates to the field of floor panels with a mechanical locking systems with flexible and shifting comb.

In particular, but not as limitation, the invention relates to locking systems, floor panels and floor panels, mechanically joined in preferably a floating floor. However, the invention is equally applicable to the construction of the panels as a whole. More specifically, the invention relates to the type of mechanically connecting the castle of systems containing flexible or partially flexible comb and/or move the comb to facilitate the installation of building panels.

The floor panel of this type is presented in WO 2006/043893, revealing a floor panel with a locking system that contains a locking element cooperating with a locking groove for horizontal connections in the castle, and flexible comb, interacting with groove ridge for connection to the castle in the vertical direction. Flexible comb is bent in the horizontal plane during the joining of the floor panel and makes it possible to install panels vertical insertion or only vertical movement. Vertical insertion" means the combination of three panels, where the first and second panels are in the United state and one swivel action connects two perpendicular edges of the new panel simultaneity is temporal to the first and second panels. This connection takes place, for example, when the long side of the first panel in the first row are connected to the long side of the second panel in the second row. The third panel is then connected by turning to the long side of the first panel in the first row. This specific type rotary action, which also connects the short side of the new panel and the second panel, referred to as "vertical insertion". Also is it possible the connection of two panels by lowering the entire panel on the merits of vertical movement to another panel.

The meaning of some terms

In the text below the visible surface of the installed floor panel is called "front side"and the opposite side panels of the floor, turned to the black floor, called "rear side". The edge between the front and the rear side is called "the edge of the junction. "Horizontal plane" means a plane that is ongoing in parallel to the outer part of the surface layer. Located directly next to the upper parts of two adjacent edges of the junction of two coupled floor panels together form a "vertical plane"perpendicular to the horizontal plane.

"Joint" or "locking system" means acting together connecting means connecting the floor panel vertical and/or horizontal resolution is quarterly. "Mechanical locking system" means that the coupling can be carried out without glue. Mechanical locking systems can in many cases also be combined with bonding. "Integrated" means made as a single piece with the panel or connected to the panel at the factory.

"Flexible comb" means a single comb, aiming along the length around the edges of the joint and forming part of the vertical locking systems, and which can be displaced horizontally in the process of connection to the castle. Ridge, for example, can be bend or be flexible or elastic part such that it can be bent along its length and get back to its original position.

"Turn" means a compound that is a turning movement, which is the angle between the two connectable or releasable parts. When turn refers to the connection of two panels of the floor, is the angular displacement, while the top edges of the joint, at least partially, are in contact with each other, in the process, at least part of the movement.

The present invention is the creation of a locking system and set of floor panels or floating flooring with new options for implementation according to various aspects of p is educause benefits. Application of the invention are floor panels of any shape and from any material, such as laminate, wood, MDF/HDF, veneer or stone.

According to the first task, invented locking system for floor panels, containing the first connecting device. The first connecting device comprises a combinational lock made with the possibility of horizontal and vertical connections in the castle with the second and third connecting devices of the second and third panels, respectively. Raman castle contains a locking element for engagement with a locking groove of the second and third connecting devices for horizontal connections in the castle. Additionally, combination lock includes a flexible ridge and groove offset made with the possibility of interaction with the groove of the flexible ridge of the second floor panel and the crest of the third floor panel.

Because locking system for floor panels according to the first objective of the invention is equipped with a flexible and shifting crest, a shift in the groove bias and executed with the opportunity to interact with the groove of the flexible ridge, as well as with a comb, it offers several advantages. The first advantage is that it becomes possible to connect one side of the floor panel with the first connecting device to two different connecting the relevant devices. The second advantage is that a firm butt, and the third is that improved the plant height between the floor panel at the junction of the short edge long edge.

Locking system for floor panels of this type is known from WO 2006/043893, as mentioned above, discloses a flexible arcuate crest, bend in the direction of the length. The disadvantage of this locking system is that if it is used at the junction between the long and short side, it weakens the joint. The first panel has a long edge of the rotary type (see figure 10a)containing the locking element and the groove of the ridge. To facilitate connection with the short side of the second panel short side is provided with a flexible ridge and groove bias. The result is a very thin section between the bottom of the groove offset and a locking groove. Thin section makes the joint weak and very likely is the destruction of the thin section, when the joint is under load.

Preferably, the length of the groove offset, at least, is equal to the sum of the width of the flexible comb and comb.

Preferably, the width E of the entrance grooves offset, at least, is equal to the thickness TT of the ridge.

Preferably, the flexible comb is offset by means of the crest.

Preferably, dockable panels are in the form of a and b with mirror image is Ino inverted connecting devices.

Preferably the flexible comb has a straight outer edge and inner edge with bendable tabs.

According to the second task, invented a set of floor panels containing the above-mentioned Raman castle on two edges of the first panel, made interoperable with the second connecting device of the second panel and the third connecting device of the third panel. The set of floor panels has advantages similar to those described above, and provides a simple installation advanced drawings.

The figure 3 shows the four steps of the preferred method of connection of the first panel with combination lock C with the second panel with lock FG. Panels are connected by insertion or only the vertical movement of the entire panel, and a flexible comb in connection stalkivaetsja in the groove offset and then springs back into the groove of the flexible comb. Panel preferably about who has the guide surfaces 22, to help overcome resistance to displacement of the flexible tongue.

Panel 1,1' floor existing state of the art, equipped with a mechanical locking system and a shift of the ridge, is described with reference to figures 4 and 5. Mechanical locking system provides connectivity to the castle of the panels to each other in the vertical direction D1, and in the horizontal direction D2.

To ensure the joining of two edges of the joint in directions D1 and D2, the edges of the floor panels have a well-known castle rail 6 with a locking element 8 on one side of the junction, later in this document referred to as "stacked bar", which interacts with a locking groove 14 in the other side of the junction, later in this document referred to as "put"panel, and provides the horizontal connection into the lock.

Mechanical locking system existing prior art contains a separate flexible comb 15, fixed in the groove 40 offset formed in one edge of the joint. Flexible comb 15 is a plot of P1 grooves located in the groove 40 offset and the protruding section P2, protruding beyond the grooves 40 offset. The protruding section P2 flexible ridge 15 at one edge of the interface communicates with the groove of the comb, made in another region of the junction.

Flexible ridge 15 has a protruding portion P2 with a rounded outer part 31 and moving is a 32 again, which in this embodiment is designed as a bevel. He has an upper surface 33 and the lower surface 35 of the offset of the ridge and the inner part 34.

The groove 40 offset has a top edge 42 and bottom edge 46 of the aperture, which in this embodiment are rounded surface 44 of the bottom, and the upper surface 43 and the bottom surface 45 offset grooves, preferably essentially parallel to the horizontal plane HP.

The groove 20 of the ridge has a surface 22 of the locking ridge interacting with flexible comb 30 and connects to the castle of edges in the vertical direction D1. Put the panel 1' has a vertical locking surface 24, which is located closer to the rear side 62 than the groove 20 of the ridge.

The sum of the width P1 of the largest area and the largest width is t P2 protruding part is full width TW. Flexible ridge is also in this embodiment, the middle section of the MS and the two extreme sections ES adjacent to the middle section. The size of the protruding part P2 and the size of the P1 section of the groove is changed in this embodiment, along the length L and the ridge separated from the two corner sections 9a and 9b. Flexible comb 15 is on one of the outside sections of the friction connection 36, which may be in the form of, for example, a small local vertical ledge. This frictional connection holds the flexible ridge in the groove 40 offset in the installation process, or in the process of production, packaging and transportation, if flexible comb is embedded in the floor panel at the factory.

In figures 5A and 5b shows the position of the flexible comb 15 after the first shift, during installation, the bottom 44 of the groove 40 offset. The offset is determined essentially by bending the flexible comb 15 along the length direction L parallel to the width W. This characteristic is significant in this sample current level of technology.

Figure 6 shows one way of implementing vertical nesting. The first panel 1" in the first row are connected with the second panel 1 in the second row. The new panel 1' is connected with its long side 5a with the long side 5b of the first panel by turning. This pivoting action also connect the short is th side 4b of the new panel with the short side 4a of the second panel. Put the panel 1' is connected to the castle with the laid panel 1 through the combined vertical and rotary movement along the vertical plane VP. The protruding part P2 has a rounded and/or angled invest part of the P2', which is in the process of inserting interacts with a sliding surface 23 invested panel 1'. The combined action of the invested part of the P2', and the sliding surface 32 of the ridge, which in the process of inserting interact with a sliding surface 23 invested panel 1', facilitates the first offset flexible ridge 15. The essential feature of this option is to position the speaker area P2 is separated from the corner sections 9a and 9b. The spacing is at least 10% of the length of edges, in this case, the visible short side 4a.

In figures 7a-e illustrates embodiments of a shift of the ridge, applicable according to the invention, without an arched crest, shown in figures 4 and 5. Ridges preferably are made of molded plastic. Any type of polymeric materials can be used, such as polyamide (nylon), Polyoxymethylene, polycarbonate, polypropylene, polyethylene terephthalate, polyethylene, or similar, with the properties described above, in various embodiments, implementation. These plastic materials when using the years of injection molding can be reinforced, for example, glass fiber, aramid fiber, carbon fiber or talc or chalk. The preferred material is glass fibre reinforced, preferably increased length, polypropylene or Polyoxymethylene.

Figure 7a shows an implementation option c first long edge L1 and the second long edge L2. The first long edge has projections continued in the plane parallel to the top side 64 of the ridge 15 and at an angle relative to the longitudinal direction of the ridge.

In figures 7a-b shows an implementation option, a top view and a side view, with the first long edge L1 and the second long edge L2. The first long edge has projections 61, continued in the plane parallel to the upper side, the upper surface 61 of the offset and the rear side, the lower surface of the offset of the ridge and at an angle relative to the longitudinal direction of the ridge. The protrusions preferably have an arcuate shape, in a particularly preferred embodiment, the ridge is equipped with a notch 62 at each protrusion 61. The cutout is preferably adapted to the size and shape of the ledge.

The protrusions preferably equipped with a frictional connection 63, most preferably near the top of the ledge, which can be given, for example, the form of local small vertical ledge. This frictional connection holds Flex is the first ridge in the groove 40 offset in the installation process, or in the process of production, packaging and transportation, if the effect of moving the comb is embedded in the floor panel at the factory.

Figure 7d shows one variant of implementation of the locking system according to the invention, showing the ridge 15 in cross section along the line B-B in figure 7c and installed in the groove 40 of the offset of the first panel 1 with combination lock C. the Upper and lower surfaces of the offset of the ridge is configured to interact with the top surface 43 of the bottom surface 45 of the groove offset. The panel contains a locking rail 6 and the locking element 8 for horizontal connections in the castle. The panel 1 is made with the possibility of connection with the second panel 1' by the way, the same is shown in figures 2 or 3. The upper surface (64) offset and/or the lower surface of the offset (65) of the crest provided in one preferred embodiment, beveled edges, presents sliding surfaces (32, 31) and an inclined surface (66) of the connections in the lock, respectively. Inclined locking surface interacts preferably c inclined surface 22 of the connecting ridge to the castle in the groove 20 of the ridge. Raman castle C may be connected with the second panel 1', is provided with a lock FG, or the third panel, is provided with a lock So

In the variants of implementation, according to the shown at F. the góra 7d, groove (40) offset is formed as a unit with the inner layer of the panel, but there may be other alternatives. Groove bias can be performed in a separate material, for example, HDF/HDF connected with wooden inner layer in the parquet floor. Groove bias can be made of plastic or metal sections in the form of channels connected to the panel, for example, locking connection, adhesive, or friction. These alternatives can be used to reduce friction and facilitate horizontal offset of the ridge in the groove bias. Groove bias may also be processed by a material that reduces friction. These principles can also be applied to the grooves of the comb.

Figure 7E shows the sprue 71 that is cut off before inserting into the groove offset.

In figures 8a-e shows different pictures of the installation, it is possible to install with locking system and a set of floor panels according to the invention. The system shown includes the floor boards of two different types a and b, respectively, and connecting devices floorboard type And along one pair of opposite areas of the edge are mirror-inverted relative to the respective connecting devices along similar pairs of opposite areas of the edge of the other floorboard type Cent. On the figure 8A shows a figure with three PA the firs floor, United short edge long edge of the panel, mirror-flipped connecting devices, panels A and B, described below and shown in figures 9a-e. The figure consists of a group of three panels in the first direction, surrounded by groups of three panels in a perpendicular direction. Figure 8b shows a square panel, connected on all sides with the long edges of the rectangular panels. Figure 8c shows the picture of the panel in the first direction are connected by edge with three panels in the second perpendicular direction, which is connected with the first long edge of the fourth panel in the first direction, the opposite edge of which is connected to three panels of the second direction, continuing in a repetitive manner. Figure 8d shows an image consisting of a group of four United square panels, surrounded by rectangular panels and United with their long edges. Figure 8e shows the traditional pattern of the parquet "in the tree". All these drawings installation includes connection of the short side to the long side. The invention creates a solution that makes possible the installation of drawings by way of vertical insertion of connecting panels durable seam in vertical and horizontal direction. The figure includes, for example, the following coupling (compare Phi is URS 9, 12):

short edge, equipped with a combination lock C, with a long edge, is provided with a lock T;

short edge, is provided with a lock FG, long edge, equipped with a combination lock C;

- the longest edge, equipped with a combination lock C, with the long edge with lock T;

short edge, is provided with a lock FG, with the short edge, equipped with a combination lock C;

- edge square panel fitted with a combination lock C, with the other end of the square panel, is provided with a lock T;

- edge square panel fitted with a combination lock C, with the other end of the square panel, is provided with a lock FG;

- edge square panel fitted with a combination lock C, with a long edge, is provided with a lock FG;

- edge square panel fitted with a combination lock C, with a long edge, is provided with a lock T;

- edge of the square panel, is provided with a lock FG, long edge, equipped with a combination lock C;

- edge square panel with lock T, with a long edge, equipped with a combination lock C.

The short edge of the panel And preferably combined with the long edge of the panel B, as is customary for installation of panels a and B.

One way of ensuring the connection of the short side to the long side is the installation of panels A and B are mirror-inverted connecting device is mi, such as shown on figure 9a-d. Two adjacent edge of the panel equipped with a combination lock C, one edge of the castle FG and one edge is provided with a lock So Connecting devices of three types C, FG, T distributed mirror-inverted on panels A and B. figure 9a shows a rectangular panel with A long and short edges. Figure 9b shows a square panel A, and figure 9b shows a square panel C.

Figure 10a shows an implementation option, which has the effect of moving the flexible ridge 15 and the groove 40 offset equipped on the fourth connecting device in the fourth panel 4 with the locking groove 14. This makes possible the connection of the short sides with the fourth connecting device, panel 4 floor-length side of the fifth panel 5, containing standard connecting device containing the locking element 8 and the groove 11 of the ridge to join the rotation with a vertical insertion. The problem is that this solution creates a thin section between the bottom of the groove 40 offset and a locking groove 14, resulting in a weak connection.

Figure 10b shows an implementation option, in which the flexible comb is removed and the connection connects to the castle in the horizontal direction only.

In figures 10c-d show how the principles of the invention can be practically applied in junction with a crest and what anaway, without any horizontal connections in the castle. Figure 10c shows a panel with a flexible comb 15 and groove 40 offset, interacting with a crest 10 panel with a comb. Figure 10d shows the panel with the groove 20 of the flexible comb interacting with flexible comb 15. Panel with groove can also connect to the panel with a crest that interacts with the groove 11.

The figure 11 shows the 10 steps of the preferred method of connection of panels a and b, square and with long and short edges in an image. Short edges are joined long edges and square panels with all edges are joined long edges.

Figure 12a shows an enlarged part of the image shown in figure 11 and how Raman distributed lock for the formation of panels a and b) and provide illustration.

Figure 12b shows how Raman distributed lock for the formation of square panels a and B. Panel are connected in a way which excludes a number of multiple joints CFG, i.e. joints between combinational lock and lock FG in line. This is an advantage, because the junction of CT, i.e. the junction between the Raman C lock and lock T offers a more durable connection in the vertical direction. Therefore, it is preferable that each of the second joint in the line is the intersection of CFG and sotdae is camping in it between the CT connections. The drawing also shows a variant of the distribution of the connecting device for the creation of what makes possible the connection of several square panels with long edges of the rectangular panels. Several edges of the square panels with combination lock can be connected with the long edge of the castle So Square panel with edge lines up with the lock hi-lock and lock T can be connected with long-edge combination lock C.

The lack of connection CT is that flexible comb panel pushes in different directions and may cause a gap between the panels. One solution to prevent this is adapting the stiffness of the flexible comb so that the force distribution panel in hand, was decreased, but it also affects the final position at the junction of the CFG. The second solution is the implementation of flexible comb with the possibility of cracking or breaking when the ridge pushes him into the groove of the shift. The third solution is a strong locking element with the guide surfaces to facilitate installation. The fourth solution is the dissolution or destruction of the ridge. Also is it possible to create the connecting edges with bevels or decorative grooves, hiding the gap.
