Description

DEMONITABLE SEAL COVER

  The present invention relates to joint covers or threshold bars intended to hide the joints between floor or wall elements. The invention relates more particularly to a joint cover having a cover profile which is fixed to a base profile by engagement. Many threshold bars include a cover profile which is fixed by snapping onto a base profile using a system with complementary grooves, for example of the "fir tail" type. Such systems are most often irreversible, that is to say that if you want to disassemble the threshold bar, you must tear off the cover profile by damaging the complementary grooves, which makes them unusable for

subsequent reassembly.

  Furthermore, if the floor is uneven, the cover profile may not be driven to the same depth at the two ends of the threshold bar, so that the grooves of the cover profile intersect the complementary grooves of the base profile. As a result, the pullout resistance

  of the cover profile is considerably reduced.

  Another disadvantage of conventional threshold bars is that the lateral forces on the cover profile caused by frequent passages deteriorate the system.

  which finally releases the cover profile.

  An object of the present invention is to provide a

  threshold bar or joint cover that is removable and reusable

  readable while having a good resistance to tearing even

on irregular supports.

  This object is achieved by means of a joint cover of the type comprising a covering profile designed to snap onto a base profile to be fixed on a support. The joint cover comprises one or more elastic intermediate parts intended for

  receive the cover profile by snapping in and out

  snap in reversibly along the base profile.

  According to one embodiment of the present invention, the base section is provided with a perpendicular tongue, one wall of which has a rounded protuberance at its end.

  intended for the engagement of intermediate parts.

  According to an embodiment of the present invention, each intermediate part comprises a U-shaped portion used for the engagement of a tongue of the cover profile and a

  side section with hook section intended to wrap the former

  rounded growth of the base profile by interlocking.

  According to an embodiment of the present invention, the tongue of the covering profile is in the shape of a fir tree, the U-shaped part of the intermediate piece having a shape in the shape of a

corresponding fir.

  According to one embodiment of the present invention, the height of the tongue of the base profile and the height of the intermediate parts are such that the U-shaped part of the parts

  intermediaries is in contact with the support.

  According to one embodiment of the present invention, the height of the tongue of the base profile and the height of the intermediate parts are such that the U-shaped part of the parts

  intermediaries is away from the support.

  The present invention also relates to an elastic fixing part of a cover profile on a base profile, comprising a U-section part intended to receive by engagement a tab of the cover profile and a hook section side part intended to be fix by snapping onto a rounded protrusion of a tab on the base profile. According to an embodiment of the present invention,

  the part is made of plastic.

  According to an embodiment of the present invention,

  the U-shaped part has a complementary fir tail shape.

  These and other objects, features and advantages of the present invention will be discussed in detail in

  the following description of particular embodiments

  made without limitation in relation to the attached figures among which:

  FIGS. 1A and 1B represent a perspective view

  tive and in section of an embodiment of threshold bar or joint cover according to the invention; Figure 2 illustrates an alternative mounting of a threshold bar according to the invention; FIG. 3 represents an embodiment of a threshold bar according to the invention suitable for very thick floor coverings; FIG. 4 represents an embodiment of a threshold bar according to the invention adapted to two coatings of the same thickness; FIG. 5 shows an embodiment of the edge joint cover according to the present invention; and FIG. 6 represents an embodiment of the seal

  of wall panels according to the present invention.

  In FIGS. 1A and 1B, a threshold bar according to the invention

  tion includes a cover profile 10 for fixing

  by engagement on a base profile 12. For this purpose, the pro-

  yarn 10 comprises a vertical tongue 14 provided, for example, with a "fir tail", that is to say that the tongue 14 comprises,

  on both sides, a succession of ramps whose inclined faces

born are turned down.

  According to the invention, the tongue 14 snaps into one or more intermediate pieces 16 instead of snapping directly into the base profile. If a single part 16 is used, its length substantially reaches that of the base profile 12. If several parts 16 are used, as shown, they are short and distributed along the base profile 12. For this purpose, the intermediate parts 16 have a U-section part constituting a groove having a profile in the shape of a fir tree to receive the tongue 14. Each intermediate part 16 is mounted by engagement on the base profile 12. The system for interlocking the parts 16 on the base 12 is planned to be

  removable. For this, as shown by way of example-

  ple, each part 16 has a hook-shaped side portion 16a which envelops a rounded protuberance provided at the upper end of a vertical tongue 12a of the base profile 12. Preferably, the protrusion of the tongue 12a is provided at level of only one of the walls of the tongue, on the side opposite to the U-shaped part of the intermediate piece 16. The remaining wall of the tongue 12a is then flat and serves as a plane of

  reference to intermediate piece 16.

  The depth of the U-shaped part of the intermediate piece

  diary 16 is chosen to allow adaptation of the cover profile 10 to the height of the coverings by varying the depth of insertion of the fir tail 14 in the intermediate piece. With this configuration, when an upward force is exerted on the covering profile 10, for example by inserting a knife or a screwdriver at one of the edges

  profile 10, the hook parts 16a of the parts 16 flexed

  feels and is released from the protuberance of the tongue 12a. The fir-tail fastening system does not give way during such an intervention because it is irreversible under these conditions. Once the hook parts 16a have been released, the profile is lifted with the intermediate parts 16 which can then be removed, if necessary, by sliding them

  along the tongue 14 to one end of it.

  In order to raise the threshold bar, the intermediate parts

  diaries 16 are again engaged on the tongue 12a of the base profile, after which the cover profile 10 is again fixed by engaging its tongue 14 in the

U-shaped parts 16.

  In order to be able to withstand several dismantling and reassembly, the intermediate parts 16, in particular their hook part 16a, must be able to bend without being deformed. Profiles 10 and 12 are generally made of aluminum. This material is not suitable for intermediate pieces 16 because it has a low elastic limit, that is to say it tends to

  keep the deformations that are imposed on it. Intermediate parts

  diaries 16 can be made of plastic or steel.

  The length of the intermediate pieces 16 determines the local rigidity of fixing the covering profile 10, while the number of pieces 16 determines the total resistance to

  tearing. In practice, these parts may have a long

  1 to 2 cm in length and they can be placed every 15 to cm to give sufficient resistance to the threshold bar.

  In addition, the intermediate parts 16 being relative-

  short and distant from each other, it is ensured that the

  Tongue 14 fir tail ramps are still engaged

  managed parallel to the corresponding ramps of the intermediate pieces 16, even if the engagement depth of the tongue 14 varies from one piece 16 to another depending on the

  soil irregularities. As a result, even if the soil is uneven

  tying, we always obtain the maximum fixing resistance.

  In the embodiment of FIGS. 1A and 1B, the

  cover profile 10 is provided to make up for a difference

  height difference between the coverings to be joined. For this, the profile 10 comprises, on one side of the tongue 14, a substantially planar part and, on the other side of the tongue 14, a part curved downwards. In FIG. 1B, the curved part of the profile 10 comes into contact with the ground 18. Illustrated at the level of the substantially flat part of the profile 10, various heights of covering which can be caught up with the configuration of the figure lB. These various heights are caught up by a more or less deep depression of the tongue 14 in the

  U-shaped part of the intermediate parts 16.

  Furthermore, the embodiment of FIG. 1B is intended for thin coatings. In this case, as shown, the base section 12 is L-shaped and the U-shaped parts of the parts 16 rest on the ground 18. The horizontal part of the section 12 is on the side opposite to the covering and is fixed to the ground , for example, by screws (visible at

Figure lA).

  FIG. 2 represents a variant of the threshold bar of FIG. 1B. The threshold bar here must catch up with the level between the floor 18 and a tiling 20. In this case, the horizontal part of the base profile 12 is on the side of the tiling 20 and is fixed by means of the adhesive 22 serving to fix the tiling 20 on the ground. The base can also be fixed in the opposite direction in

that case.

  Furthermore, there is shown in Figure 2 a room

  intermediate 16 raised relative to FIG. 1B, this enhancement

  sement being intended to catch up with the relatively large height of the tiling 20. The part 16 is always in contact

with the ground.

  Figure 3 shows an embodiment of bar

  threshold according to the invention intended for a partial floor covering

  especially thick 24. A base section 12 ′ is used which has an elevated tongue 12a ′. The intermediate part 16 is here the same as in FIG. 1B but it is no longer in contact

with the ground.

  By way of example, the curved downward part of the covering profile 10 rests here on a coating 26 of

  thinner than the coating 24.

  FIG. 4 represents an embodiment of a threshold bar according to the invention intended to cover the joint between two

  coatings of the same thickness. Compared to the previous figures

  teeth, the cover profile 10 'is symmetrical and flat.

  Figure 5 shows an embodiment of cover

  border seal according to the present invention, intended to hide the

  joint between a floor covering and a wall. The overlapping profile

  really 10 "here has a single flat part extending over

  above the base profile 12 and resting on the covering. The intermediate part 16 rests on the ground and is in contact with

the wall.

  FIG. 6 represents an embodiment according to

  the invention of wall panel joints. The cover profile

  ment 10 'is flat as in the case of FIG. 4. The base profile 12 "is here in" T "and extends beyond each of the edges

  of the two panels to be joined. The U-shaped parts of the intermediate parts

  diaries 16 rest on the 12 "base profile. The base profile

  12 "is fixed to the wall 30, for example by screws.

  Of course, the present invention is susceptible of various variants and modifications which will appear to those skilled in the art. In particular, the fir shank fastening system described can be replaced by any other interlocking system with variable depth, irreversible or not. Of course, the two interlocking systems of the intermediate parts 16 can

to be reversed.
