Description

The present invention relates to the field of laying a profile on a wall adjoining a wall the edge of a coating, in particular by gluing the profile, and with covering by the profile of the edge of said coating. In this field, the subject of the invention is a device and a method for temporarily clamping a profile against a wall that adjoins the edge of a coating, in order to maintain and fix the profile on the wall, particularly during setting. glue. The profile is for example a finishing profile, such as a plinth or quarter round, placed between a vertical wall and a floor covering, or a finishing profile, such as a cornice, placed between a ceiling and a covering wall, or a finishing profile, such as a vertical corner strip, placed between a first vertical wall and the wall covering of another vertical wall transverse to said first wall.

PRIOR ART It is customary to fix decorative finish skirting boards on a wall, such as a wall or a partition, in order to make an aesthetic transition between said wall and a floor covering, such as a carpet or a parquet, of which the edge adjoins the wall. Generally, the flooring adjoins the wall without touching it, with a small space, if any, for expansion of the floor covering between the wall and the edge of the floor covering. Once the plinth is fixed against the wall, this expansion space is hidden by the plinth. The skirting board is also fixed in height on the wall so that it rests on the floor covering or on the edge of the floor covering by creating, between the surface of the floor covering and the plinth, a residual gap which is generally of small width.

It is also customary to fix other finishing profiles on a wall, such as for example a cornice placed between a ceiling and a wall covering, or a corner strip placed between a first vertical wall and the wall covering of a wall. another vertical wall transverse to said first wall. When the finishing profile is to be fixed to the wall by gluing, it is necessary, during the installation, to temporarily hold the profile against the wall by continuously applying pressure to the profile for a period of time necessary in order to allow time for the glue to take and securely fix the profile. This pressure can be exerted manually by the installer during the setting time of the glue. But this operation makes the installation tedious for the installer and increases the exposure time, the installer is not available to paste another profile during the setting time of the glue. Where applicable, in the case of a skirting-type finish profile placed between a vertical wall and a floor covering, the installer may use various means such as heavy objects to exert the required pressure, but this implementation is tedious and impractical. Also, the installer can temporarily nail the profile on the wall to hold it against the wall. But the use of nails damages the aesthetics of the profile. In addition, once the profile is pressed against the wall, if we remove the nails, we are forced to reseal the holes caused in the profile by the nails. OBJECT OF THE INVENTION The invention aims primarily to propose a new technical solution for temporary clamping of a profile against a wall, which simplifies the fixing, in particular by gluing, of the profile against a wall, and which advantageously allows the installer avoid having to manually maintain the profile during the setting of the profile, or to avoid using various means such as heavy objects to maintain the profile, or to avoid having to nail the profile.

DETAILED DESCRIPTION In the particular variant of FIG. 1, the kit for clamping a finishing profile against a wall comprises a clamping piece 1 and two connecting pieces 2A, 2B, the clamping piece 1 being able to be slipped and slid on each connecting piece 2A or 2B.

Each connecting piece 2A, 2B is more particularly constituted by a tongue 20, for example made of plastic, comprising a main portion 200, which ends at a first front end with a tongue portion 201 of small thickness e. This tongue portion 20a thin e is extended by a hook 202.

In this variant, but not limited to the invention, the tongue portion 201 of very small thickness is connected to the main portion 200 of the tongue 20 by a recess 201a, so that the tongue portion 201 of low thickness is aligned with the main portion 200 of the tongue 20, but being positioned in a lower plane. This recess 201a makes it possible to raise the main part 200 with respect to the hook 203, and thus to facilitate the gripping of this main part 200 of the tongue by the baseboard installer. This recess is however optional and could be omitted in another variant, the parts 200 and 201 of the tongue 20 may have their upper surfaces substantially coplanar. In the variant of Figure 1, in order to save material, the connecting piece 2A or 2B is a tongue of small width 1, and the thickness of the main portion 200 is low. In another variant, the connecting piece 2A or 2B could be wider and / or the main part 200 could have a different geometry, and in particular be thicker.

The main part 200 of each connecting piece 2A or 2B comprises a portion 200a adapted to allow unidirectional locking of the clamping piece 1 in different clamping positions. This blocking portion 200a comprises a plurality of inclined locking notches 200b, which are formed in the upper face of the main part 200. The connecting piece 2A differs from the connecting piece 2B by the geometry of its hook 203. The hook 203 of the connecting piece 2A has an L-shaped profile, and is adapted to hang the connecting piece 2A on the edge of a rigid floor covering, such as for example parquet or tiling. The hook 203 of the connecting piece 2B has a U-shaped profile, and is adapted to hang the connecting piece 2B on the edge of a thinner and non-rigid coating, for example carpet-type or also paneling blades so keep the connecting piece on the edge during installation. The clamping piece 1 has in the lower part a through hole 10 allowing it to be threaded onto the main part 200 of a connecting piece 2A or 2B, and a U-shaped part 11 (FIGS. 6 and 7) serving to guide in translation the clamping piece 1 relative to the main part 200 of the connecting piece 2A or 2B on which the clamping piece 1 is threaded. The clamping piece 1 also comprises in the upper part a portion 12 with a clamping stop function. In the variant of Figure 1, this clamping stop 12 forms a recess 12a towards the front of the clamping piece relative to the wall of the clamping piece 1 in which is formed the through hole 10. As it will appear more clearly later, this recess 12a facilitates the final cut of the connecting piece 1 at the end of laying. This step 12a is however optional.

With reference to FIG. 2, the clamping piece 1 can be threaded onto the main part 200 of the connecting piece 2B (or 2A) by introducing, into the through orifice 10 of the clamping piece 1, the free end rear 200c of the connecting piece, located opposite the front hook 203, then sliding the clamping piece 1 in the tightening direction E along the main portion 200 of the connecting piece 2B (or 2A) in the direction of the front hook 203. Once threaded onto the connecting piece 2A or 2B, the clamping piece 1 has a single degree of freedom with respect to the connecting piece 2A or 2B allowing it to slide relative to the workpiece. link. With reference to FIG. 3, the clamping piece 1 comprises a locking abutment 13 which cooperates with the locking notches 200b of the notched part 200a of the connecting piece 2B (or 2A) so as to block in translation. the clamping piece 1 relative to the connecting piece 2B (or 2A) preventing it from sliding backwards in the direction D facing away from the front hook 203, and without hindering the sliding of the piece 1 forwardly in the tightening direction E (towards the front hook 203). The locking notches 200b thus make it possible to define different clamping positions of the clamping piece 1 with respect to the connecting piece 2B (or 2A), each clamping position being characterized by a gap EC (FIG. 3) between the workpiece 1 and the attachment means 203 of the connecting piece which is different for each clamping position. The clamping piece 1 and the connecting pieces 2A and 2B can advantageously be manufactured in large series and at low cost, for example by plastic injection. The main successive steps of laying a plinth P on a vertical wall, such as a wall M, adjacent to the edge B of a floor covering R, will now be detailed with reference to FIGS. 4 to 11.

Figure 4 Before placing the baseboard on the wall M, the hook 203 of the connecting piece 2A (or 2B) is hooked on the edge B of the floor covering R, by positioning it in the expansion space 3 (FIGS. 10 and 11) provided between the wall M and the floor covering R. FIG. 10 illustrates an implementation of the connecting piece 2B on the edge B of a thin and non-rigid floor covering R , of type for example carpet. Figure 11 illustrates an implementation of the connecting piece 2A 10 on the edge B of a floor covering R rigid, parquet type, and may have a greater thickness if necessary. The hook 203 allows the locking in translation of the connecting piece 2A or 2B relative to the floor covering R, when the binding part 2A or 2B is pulled in the direction D substantially perpendicular to the edge B of the covering of ground R and oriented rearward opposite said edge B and hook 203. FIG. 5 The wall M and / or the rear face of a plinth P is glued, and the plinth P is positioned against the wall M, such that the portion 201 of small thickness of the connecting piece 1 is positioned between the skirting P and the floor covering R, the lower edge of the skirting P being preferably in contact with the portion 201 of small thickness of the connecting piece 2A or 2B. The material constituting the skirting P is of no importance for the invention, the plinth P being able to be made in different materials. This may be, for example, and in a nonlimiting and non-exhaustive manner, a solid wood plinth, an MDF skirting to be painted or partially covered with a single-layer decorative coating or multilayer, plastic film type or melamine paper, 30 of a PVC plastic skirting board, or a tile baseboard. Figure 6 The clamping piece 1 is assembled on the connecting piece 2A or 2B by threading it on the main part 200 of connecting piece 2A or 2B. Figure 7 The clamping piece 1 is slid along the connecting piece 2A or 2B, in the tightening direction E, which is substantially perpendicular to the edge of the floor covering R, and which is oriented towards the hook 203, for bringing the clamping piece 1 into a clamping position in which the front clamping stop 12 of the clamping piece 1 is in contact with the baseboard P.

In this clamping position, the clamping piece 1 is locked in translation, in the opposite direction D, by the locking stop 13 cooperating with one of the locking notches 200b of the connecting piece, and thanks to the traction exerted on the clamping piece 1 by the edge B of the floor covering R in the clamping direction E, the baseboard P is clamped between the wall M and the clamping abutment 12 of the clamping piece 1. no need to manually press the skirting P to keep it pressed against the wall M during the time of setting of the glue, and can thus advantageously perform other tasks, including continuing the installation of other plinths in the same way, without having to wait for the end of the glue taking time. In the accompanying figures, using a single clamping piece 1 and a single connecting piece 2A or 2B. Of course, depending on the length of the skirting P, it will be possible to implement several pairs of clamping piece 1 and connecting piece 2A or 2B judiciously spaced and distributed along the baseboard P. Figure 8 Once the duration of taking the glue is complete, and that the plinth P is fixed by sticking reliably to the wall M, is cut, for example by means of a blade L of cutter, the portion 201 of small thickness of the piece of connection 2A or 2B, either closer to the lower edge of the baseboard P or in the gap created between the lower edge of the baseboard P and the floor covering R, so as to separate the hook 203 from the rest of the room link 2A or 2B. The recess 12a of the clamping piece 1 facilitates the passage of the cutting blade L under the clamping stopper 12.

Figure 9 Once this cut is made, the hook 203 and a small portion of the thin portion 201 are lost and remain in position or are pushed behind the skirting P with a blade tip cutter, while the clamping piece 1 and the cut connecting piece 2A or 2B are removed. Since the portion 201 of the connecting piece 2A or 2B has been positioned under the skirting P during installation, it is preferable that the thickness e of this portion 201 be as low as possible without, however, compromising the integrity mechanical portion 201 during tightening, so that there remains between the skirting P and the floor covering R as small a gap as possible. In practice, it is possible to make a plastic connecting piece 2A or 2B whose thickness e of the portion 201 is between 0.5mm and 0.1mm. It should be noted here that this portion 201 of small thickness does not need to be rigid and can be flexible or flexible, and must be able to withstand the tightening tension without breaking. The connecting piece 2A or 2B that has been used is a disposable consumable, while the clamping piece 1 can possibly be reused.

FIGS. 12 and 13 show another variant of clamping piece 1 'that can be slidably mounted on another variant of connecting piece 2C without locking catches. In this variant, the clamping device comprises a locking means, in the form of a clamping screw 14, which makes it possible to immobilize by clamping the clamping piece 1 'with respect to the connecting piece 2C in different positions of Tightening.

The invention is not limited to the embodiments and implementations of the appended figures. In particular, in another variant, the movable clamping piece may be designed to be assembled with the connecting piece in different clamping positions, without it being necessary for the clamping piece to slide relative to the connecting piece. The invention is not limited to the clamping of a plinth placed between a vertical wall and a floor covering adjacent the vertical wall, but extends to the clamping of any type of profile against a wall adjacent the edge of a coating . For example, and non-exhaustively, the profile may have in cross section a completely different geometry than that of the plinth illustrated in the accompanying figures, and for example the profile may form a quarter round. The profile can be a finishing profile, such as a cornice, placed between a ceiling and a wall covering. The profile may be a finishing profile, such as a vertical corner strip, placed between a first vertical wall and the wall covering, for example a panel-type wall covering, placed on another vertical wall transverse to said first wall. .
