Description

The invention relates to a device for fixing a built-in element.

  which can be mounted in the location opening of a support plate, rests by its edge on the surface of the latter and can be fixed to it by at least one retaining clip comprising a first shaped end a branch for attachment to the insert, a second branch-shaped end, free and capable of engaging under the underside of the plate with a certain clamping pressure and if between the two branches an elastically deformable in the form of an arc, the deformation of which determines the clamping pressure. A fixing device of this type is known from document DE 44 11985. In this device the clamping pressure is exclusively determined by the force which is produced by the opening of the arc-shaped part when the free ends of the staples are pushed under the support plate. To obtain sufficient clamping or support pressure, the widening of the arc must be relatively large, which requires

  the use of an additional gripping strap.

  To this disadvantage is added that the pressure of

  clamping or support is not adjustable.

  The present invention aims to provide a fixing device of the above-mentioned type, which overcomes

  the disadvantages which have just been stated.

  To achieve this object, the fixing device according to the invention is characterized in that the retaining clip comprises means for adjusting the clamping pressure. According to a characteristic of the invention, means for adjusting the clamping pressure comprise a screw which passes through the retaining clip at the level of the opening of the arcuate part and constitutes a means

  for widening and narrowing the arch.

  According to another characteristic of the invention, the screw bears by its head on the external face of an end region of the arc and engages a thread which is

  provided in the other end area of the arc.

  The invention will be better understood and other aims, characteristics, details and advantages thereof

  will appear more clearly in the description

  Explanatory which will follow made with reference to the appended schematic drawings given solely by way of example illustrating two embodiments of the invention and in which: - Figure 1 is a schematic side view of a fixing device according to the invention in its rest position; - Figure 2 shows the fixing device of Figure 1 in its working position; and - Figure 3 is a schematic view of another embodiment of a retaining clip according to the invention. In FIGS. 1 and 2, the reference number 1 designates a retaining clip according to the invention, for fixing a built-in element 2 of which only the edge is shown, in the location opening 3 of a plate support 4. The built-in element 2, which could for example be a sink bowl, a drip bowl or a hot plate, rests by its edge 5 curved on the edge 6 of the location opening. The end 7 of the curved edge 5 projects into the location opening 3 and is folded upwards to allow hooking of the retaining clips 1. The end 7 could also be formed by a part fixed to a flat edge . Several staples are distributed around the periphery of the insert. A retaining clip according to the invention 1 comprises a first essentially straight branch 9 for fixing the clip to the insert 3, a second branch 10 for fixing to the support plate and a part in the form of a arc 12, located between the two branches 9 and 10. The retaining clip is preferably made of strip steel for springs or plastic. The branch 9 is curved at its free end for the formation of a hook 14. This hook allows the hooking of the clip on the free edge 7 bent upwards of the built-in element. The second branch 10 engages, for fixing the clip to the support plate 4, under the edge of the lower face 15 of the location opening 4, as can be seen in FIG. 2. The free edge of the branch 10 is curved substantially rectangular inward to form a claw 11 for penetration into the plate 4. The claw can be provided

teeth.

  The arc-shaped part 12 between the branches 9 and allows elastic deformation of the clip so that it can be made to pivot from its rest position shown in FIG. 1 to its working position according to FIG. 2 , in which branch 10

  engages under the support plate 4.

  The opening width of the arch 12 and thus the pressure with which the branch 10 is supported on the underside 15 of the support plate 4 is adjustable by a screw 16. This screw passes through the clip in the area d entrance to the arc 12. It rests by its head 17 on the external face of the lower entry zone 18 of the arc 12 and engages a thread 19 formed in the upper entry zone 20 of the bow. In the lower zone 18 is only provided a passage hole 21. So that the head 17 of the screw does not protrude in the mounted state of the insert 2 beyond the clip down, the zone 22 of the arc 12 towards the branch 10 is bent somewhat downwards and thus deformed in S. To ensure good support for the screw head 17, the

  area around the through hole 21 is flat.

  For fixing the element 2 in the location opening 3 of the support plate 4, an appropriate number of retaining clips are freely hung by distributing them around the periphery of the built-in element, with the curved edge. 7 as can be seen in FIG. 1. The arcuate part 12 of the staples is opened by the screw 16 so that the staples can be made to pivot without using a clamp gripping their rest position according to FIG. 1 in the working position shown in Figure 2, in which the branch 10 engages under the inner face 15 of the support plate 4. For this purpose the arc can be widened so that only a relatively small force can be executed manually suffices. To allow the opening of the arch, the screw 16 is adjusted so that its head 17 is at a distance from the bearing surface, necessary for the widening of the arch. After pivoting of the clips in the working position, with the claws 11 being pressed on the underside 15 of the plate 4, the screws 16 are tightened until the desired tightening pressure is reached. It is also possible, according to the embodiment shown in Figure 1 in broken lines, to allow the arc 12 to widen until the clip can be caused to pivot in its working position according to the Figure 2 without manual deformation. Thanks to the screws 16, the clamping pressure of the staples can be adjusted to the desired value, despite certain

  differences in thickness of the support plates.

  Figure 3 shows an embodiment of a retaining clip according to the invention, the free end of the branch 10 is bent outward at 23 to form an inclined ramp which is configured so that the edge lower 24 of the site opening comes to bear on this ramp during

  pivoting of the clips in the fixing position.

  The arc 12 is widened by sliding on the edge 24 under the effect of the pivoting force. The upper face of the branch 10 can be provided with teeth 25 to obtain an anchoring effect on the branches 10 in the

  underside of the support plate.

  In the embodiment of the invention according to FIGS. 1 to 3, the upper end of the branch 9 is produced in the form of a hook. Within the framework of the invention, the fastening of the clip to the built-in element can also be carried out under any other

appropriate form.

  The retaining clips according to the invention simplify, essentially by means of the screws 16, the mounting of a recessed element in a work plate while allowing adaptation to different thicknesses of the plates.
