Abstract

This locking system comprises a wire element (11) housed in the factory in a groove, the latter having at its end a lateral thrust means (14). When pulled, this wire element (11) laterally pushes a beveled end locking insert (9), which is factory-placed in a groove (6) of a floorboard in advance of the means (14). ) on its beveled end (16), to move it to and in the opposite groove (7) of the parquet board to be assembled. The linear movement of traction on the wire element and therefore that of its thrust means (14) is converted by the beveled end (16) of the locking insert into a lateral translational movement which penetrates this locking insert in the opposite groove and occupy all its volume.

Description

The invention relates to a locking system between two transverse or longitudinal edges joining two successive blades of a synthetic floor or a similar structure of coating or facing or other.

It is mainly in the field of wall, floor or wall cladding and in that of floating floors consisting of thin slats of a melamine composite material whose upper face is provided with a decorative sheet covered with a film or a transparent protective layer.

Floating floors or other flat structures trim or finishing are made by the juxtaposition of blades as follows. The longitudinal edges are assembled by engaging laterally in each other according to the tongue-and-groove joint technique. The transverse horizontal blocking between the blades results from the embedding of a linear and longitudinal projecting shape in a cavity of complementary shape existing in correspondence along each of the edges to be assembled. This longitudinal immobilization could yield by the output of the linear projection of its receiving shape following a vertical movement of the ends. It is important to provide a suitable means that allows both the leveling of the two ends and a vertical blocking thereof at the junction so that they remain well joined and in coplanar extension. This constraint results from technical and aesthetic imperatives. There are various inventions which each provide a satisfactory mechanical solution from the point of view of vertical blocking but very often inconvenient to implement. It may especially be mentioned the invention corresponding to the French patent application No. 10/03852 filed September 29, 2010 disclosing a locking system for the lateral ends of two successive strips of parquet and which implements a flat insert ribbon type introduced into an inner channel formed by the juxtaposition of two median grooves facing two junction edges of the blades. The contact of the two flat front surfaces in the upper part of these two edges ensures the vertical locking and a perfectly planar junction, while partially embedded forms

inferior provide lateral and longitudinal immobilization. This blocking system is satisfactory from the point of view of the vertical blocking but the introduction of the ribbon type flat insert into the inner channel formed by the juxtaposition of two median grooves facing it is long and tedious, especially in the case of its introduction into the longitudinal interior canal. This results in a need for an improvement of this locking system which makes it easier and faster to set up a locking insert in the inner channel provided for this purpose.

The solution of the invention is to provide a device for quick and easy introduction of a locking insert in an inner channel formed by the juxtaposition face to face of two median grooves facing each formed in a transverse or longitudinal edge of junction of a blade of a synthetic parquet or a similar structure of coating or facing. This device comprises a wire element housed in a central groove of a floorboard. It comprises an end bulb constituting a lateral thrust means of the locking insert. When pulled, the initial linear movement movement of the end of this wire element is transformed by action on an oblique ramp in an initial lateral thrust on the locking insert for example on its beveled end. It forms between the end of the locking insert and the bottom of the adjacent groove an introduction space for the end of the wire element in which it engages and progresses. It is the path of this end of the wire element along the longitudinal edge of the locking insert and between it and the bottom of the adjacent groove which will cause the lateral displacement of the locking insert at the end of which it will be in its final vertical blocking position of the junction between the two blades. During this movement, this locking insert being previously housed in a first central groove of a first floorboard is pushed towards the middle groove facing a second floorboard by the conversion of the linear traction movement and the linear displacement of the end bulb of this wire element on the end, for example bevelled end of the locking insert in a lateral translational movement of the locking insert. More specifically, the locking system of the invention is provided for the joining of two opposite edges assembled by

interlocking two successive blades of facing, parquet or the like, these blades having a first joining edge having an assembly structure for example double-fitting male / female forms and a second opposite edge having an assembly structure forms complementary to achieve and stabilize the assembly by interlocking edge-to-edge of two successive blades when their opposite edges junction are placed opposite, these edges each having in a front edge a central groove which form a channel when they are placed opposite one of the other, this channel being provided to receive a rectilinear locking insert housed before assembly in one of the grooves and for vertically immobilizing the blades together at the assembly. This locking system is characterized by the following means: the locking insert is movable transversely of the central groove in which it is housed towards and in the opposite median groove; a wire element housed in a longitudinal groove extending along the central groove serving as initial housing for the locking insert and moving along it, this wire element having at one of its ends a means for lateral thrust for lateral displacement of the locking insert; and by: - a motion conversion means between the linear movement corresponding to the traction on the wire element and the lateral displacement movement of the locking insert towards and in the groove opposite to that in which it is initially housed. It is thus possible to provide original flooring strips having this pre-mounted locking device in a central groove together with a locking insert also previously housed in this central groove. When assembling two floorboards having these means premounted, once their opposite median grooves have been placed opposite, simply pull on the free end of the wire element to slide the lateral thrust means of the latter along the central groove where the blocking insert is housed to laterally move it partially in the opposite median groove of the facing floorboard to achieve the vertical blocking of the edges of the floorboards or like.

Once completely removed from the middle groove where they were originally premounted, the wire element and its lateral thrust means can be discarded. The solution of the invention makes it possible to easily and rapidly place the locking insert in vertical locking position of the edges of the floorboards. Other characteristics and advantages of the invention will appear on reading the detailed description which follows, description made with reference to the accompanying drawings, in which: - Figures 1 to 3 are cross-sectional views of two floorboards facing each other and equipped with the locking system of the invention, these views illustrating the introduction of a beveled end locking insert by the use of the invention; - Figures 4 to 6 are top views corresponding to the sequences of Figures 1 to 3, wherein the floorboards are truncated in length; - Figure 7 is a perspective view illustrating the removal of the wire element of the invention for the establishment of the locking insert; FIG. 8 is a detailed view of the zone encircled in FIG. 7; Figures 9 to 12 are perspective views illustrating several exemplary shapes for the lateral thrust means of the invention; FIGS. 13 to 16 are perspective views illustrating several examples of shapes for the locking insert of the invention; - Figures 17 and 18 are top views illustrating the establishment of a right-end locking insert by the use of the invention; and - Figure 19 is a cross-sectional view of two parquet boards facing each other, wherein the inner channel formed by the juxtaposition of two median grooves is oblique and in which a groove is provided in the blocking insert for housing the wire element. By convention, the term "floorboards" will be used hereinafter for any support or facing or similar application of this invention. Usually, the parquet strips 1 have complementary assembly structures 2 and 3, for example double

recess, on their transverse and / or longitudinal edges opposite junction 4 and 5 which allow to assemble edge to edge two successive parquet strips 1 when their opposite edges junction 4 and 5 are placed opposite and immobilized horizontally by interlocking their complementary assembly structures 2 and 3. These assembly structures 2 and 3, for example double-type type of male / female forms, ensure a horizontal horizontal immobilization of parquet boards 1 assembled to each other. In their transverse and / or longitudinal joining edges 4 and 5 having the assembly structure 2 or 3, the floorboards 1 concerned by the invention each have a central groove respectively 6 and 7 which form a channel 8 when they are placed next to each other. According to the invention, a locking insert 9 is provided to be housed in this channel 8 on either side of the junction line between two assembly blades in order to immobilize them vertically after placing the insert of blocking. This locking insert 9 is preferably a rectilinear insert, of generally planar shape, for example of the ribbon, rod, rod or other type, which may have reliefs on its horizontal faces. It can be produced in long lengths and cut into end segments at a skew of length corresponding to the use, that is to say practically to the width or length of a floorboard depending on whether it is a locking insert 9 for respectively transverse or longitudinal edges. In general, this locking insert 9 may have any shape adapted to its use, without departing from the scope or scope of the invention. Several examples of shapes are given in a nonlimiting manner for the locking insert 9 in FIGS. 13 to 16. In FIG. 13 it is a rectilinear insert of generally planar shape having transverse reliefs of the cross-piece or lip type from a central soul. In Figure 14 it is a rectilinear insert of generally planar shape having a flat upper horizontal face and a series of parallel crosspieces over the entire thickness of the body of the insert. In use, such a blocking insert 9 can be perfectly turned over so that its flat horizontal face is the lower face, while it is then its upper horizontal face that has reliefs.

In Figure 15 it is a rectilinear insert of generally planar shape having a sectional shape in two "C" contiguous back to back connected in their middle by a vertical section. In Figure 16 it is a hollow rectilinear insert, of generally flat shape, rectangular section. According to the invention, one of the medial grooves 6 and 7 of a floorboard 1 is deep enough to allow the blocking insert 9 to be entirely housed initially without it protruding outwardly from the groove median (Figures 1 and 4).

Similarly, the channel 8 provided for receiving the locking insert 9 in the vertical locking position of the parquet strips 1 has a width substantially equal to that of the locking insert 9 and its bottom is preferably offset downwardly relative to the central groove 6 or 7 of initial accommodation of the blocking insert 9, this central groove 6 or 7 having for this purpose on its lower face a recess in a ramp descending outwardly forming the separation of the two planes constituting its lower surface. The central groove 6 or 7 of the initial housing of the locking insert 9 has a height intended for the locking insert 9 to be housed tightly therein, so that it can not accidentally come out of the central groove 6 or 7 where he is lodged. The channel 8 has a height designed so that the locking insert 9 is housed there with an almost zero clearance to prevent its displacement once in vertical locking position of the parquet strips 1.

The locking system between the two transverse and / or longitudinal joining edges 4 and 5 of two parquet strips 1 comprises a wire element 11 housed in a longitudinal groove 12, for example, provided along the entire length of the central groove 6 or 7 of initial housing of the locking insert 9 of a first floorboard, middle groove 6 or 7 which forms the channel 8 to which the blocking insert 9 must be inserted when it is placed facing the opposite median groove 7 or 6 of a second parquet blade 1. The longitudinal groove 12 in which the wire element 11 is housed may for example be located at the bottom of the central groove 6 or 7 serving as initial housing for the locking insert 9 or be provided in the longitudinal edge of the locking insert 9 looking towards the bottom of the central groove 6 or 7 serving as an initial seat for the locking insert 9. This wire element 11 has at one of its ends 13 a means of pous lateral end 14 for lateral displacement of the locking insert 9, while its other end 15 is free or provided with a gripping element or traction. The end 13 comprising the thrust means will hereinafter be called the active end. The lateral thrust means 14 is for example a bead, an excess thickness or a bulb or a piece forming a slider or any other local blister or enlargement of section forming part of, secured to or connected to the end of the wire and in general, a sufficient increase in end diameter to be greater than the width of the longitudinal groove 12 or any equivalent means. According to one of the variants, the locking insert has a beveled end 16, that is to say obliquely downwardly sloping towards the bottom of the groove 6 or 7 or the longitudinal groove 12. The final part of the element wired wire 11 is located initially substantially at the corresponding end, for example beveled 16 of the locking insert, preferably at one end of the longitudinal groove 12, while the free end 15 of this' wired element 11 for example protrudes outwardly at the opposite end of the longitudinal groove 12. The locking insert 9 having an end for example beveled 16 is housed at the bottom of a central groove 6 or 7 of the blade parquet 1 having the longitudinal groove 12 occupied by the wire element 11. The beveled end 16 for example is on the side of the side thrust means 14 of the wire element 11. In this configuration, the block insert ge 9 does not preferably protrude from the central groove 6 or 7 of initial housing of the locking insert 9. The first portion 17 of the end, for example beveled 16 of the locking insert 9 is on the side of the lateral thrust means 14, namely on the bottom side of the middle groove 6, while the second portion 18 of the beveled end 16, for example, of the locking insert 9 is towards the outlet of the central groove 6, is housed the latter.

The lateral thrust means 14 that comprises the active end 13 of the wire element 11 may have a suitable shape with a double oblique or divergent conical ramp beyond the end.

a conical or spherical shape or engagement wedge so that, when the wire element 11 is pulled along the groove 12, for example at the bottom of the central groove 6 along which it slides, its thrust means lateral 14 engages the end for example beveled 16 or only beveled corner of the locking insert 9 to laterally push this end outwardly (Figures 2 and 5). When the wire element 11 is pulled over the entire length of the central groove (FIGS. 3 and 6), the displacement of its active end along the bottom of the central groove 6 and against the end 16, for example bevel oblique ramp causes a lateral thrust on the blocking insert 9 which moves it to and then in the middle groove 7 opposite until the wire element 11 and its active end has moved over the entire length of the insert along its inner longitudinal edge 19 comes free end of stroke at the end of the groove 6. It then constitutes a disposable set as any consumable. The transverse position of the locking insert 9 is guaranteed by the ramp recess 10 which acts in the manner of an antirecul stop. This combination provides a solid and stable assembly. All of these operations are possible provided that the locking insert 9 has sufficient resistance to longitudinal displacement to prevent traction on the wire element moves longitudinally thereof. Its adjustment in the grooves 6 and 7 and its reliefs are provided for this purpose. Thus the invention is characterized by a motion conversion means between the linear movement corresponding to the traction on the wire element 11 and the lateral displacement movement of the locking insert 9 towards and in the opposite groove 7 or 6 to the one in which it is housed initially. In the case where the end of the locking insert 9 is beveled 16 downwardly sloping forming an oblique ramp towards the bottom of the central groove 6 or 7 in which the locking insert 9 is housed at the origin, this means of conversion of movement is composed on the one hand of the beveled end 16 of the locking insert 9 and on the other side of the lateral thrust means 14 present at the end adjacent to the wire element 11. The means lateral thrust 14 present at the active end of the wire element 11 is then an end piece which cooperates in a first step with the oblique ramp of the beveled end 16

of the locking insert 9 for the initial lateral thrust of the locking insert 9. In the case where the end of the locking insert 9 is not beveled, but has for example a simple cut corner obliquely on the side of the end of the wire element 11, designed to cooperate with the lateral thrust means 14, the motion conversion means is composed firstly of the active end of the wire element 11 which has an oblique or conical ramp shape and secondly, the end of the locking insert 9.

Thanks to the invention, when the wire element 11 is pulled, the locking insert 9 is progressively put in place in the channel 8, and not put in place at one time, which provides better accuracy and allows to compensate for any assembly defects of the floorboards 1.

This progressive placement of the locking insert 9 in the channel 8 also avoids any possible elastic deformation of the parquet boards 1 or the locking insert 9, which makes it possible to have a more resistant assembly for the floorboards. parquet 1. Several examples of shapes for the lateral thrust means 14 are given in FIGS. 9 to 12. By way of example only, the lateral thrust means 14 may be in the form of a sphere (FIG. 9). , a spheroid, a cone whose tip is located on the side of the end 13 of the wire element 11 (FIG. 11) or of any shape, for example of the roller type whose edge near the end 13 of the wire element 11 is rounded (FIG. 10) or pointed (FIG. 12). According to a variant shown in Figures 17 and 18, the locking insert 9 may have straight ends and not beveled in this case, the lateral thrust means 14 has a shape adapted to such ends for the locking insert 9, especially a pointed form (Figure 12) which allows the lateral thrust means 14 to exert a lateral spacing force between the inner longitudinal edge 19 of the locking insert 9 and the bottom of the central groove 6 or 7 where it is initially housed.

In fact, the channel 8 provided for receiving the blocking insert 9 in the vertical blocking position of the floorboards 1 is offset downwards with respect to the middle groove 6 or 7 of the initial housing of

the locking insert 9, once housed in this channel 8 the locking insert 9 is found in this channel and is unlikely to come out. Other means may be provided by those skilled in the art to hold the locking insert 9 in position in the channel 8.

Obviously, the invention is not limited to the preferred embodiment described above and shown in the various figures, the skilled person can make many changes and imagine other variants without leaving the scope or of the scope of the invention.

For example, it is possible to provide the longitudinal groove 12 where the wire element 11 is housed, not in any additional way along the entire length of the central groove 6 or 7 of the initial housing of the locking insert 9, but in the edge longitudinal 19 and the entire length of the locking insert 9 located inwardly of the central groove 6 or 7, as shown in Figure 19. Similarly, as shown in Figures 17 and 18, it is possible to provide a gripping element 20 at the free end 15 of the wire element 11 which allows the end user to pull more easily on the wire element 11. This gripping element 20 can advantageously be of the same shape the lateral thrust means 14, which allows for example to use the same mold for their manufacture. Finally, as shown in FIG. 19, the middle grooves 6 and 7 may be horizontal, but also obliquely with respect to the upper face of the blades 1, which makes it possible to provide these median grooves 6 or 7 in a zone of more material. important. Thus, there is more material around each middle groove 6 or 7 which provides better strength for the transverse and / or longitudinal edges opposite junction 4 and 5 of the floorboards.
