Description

The present invention relates to an improved clamp intended to be

mounted on a stud bolt.

  It is common practice, especially in the automotive industry, to weld a T-shaped metal dowel consisting of a head and a rod on a sheet metal panel and then attach objects, such as cables, moldings or upholstery on the stud (s) using a metal or plastic clamp. To this end, many plastic clamps have been proposed and in many cases this clamp is provided with a slot in the form of a keyhole to allow the clamp to be mounted.

  sliding, on the T-bolt. Until now, the shape of this slot

  in this type of clamp was difficult to obtain by molding and it was necessary to respect very tight tolerances to ensure that the clamp is always firmly mounted on the stud without the possibility of detaching under the effect

a strong vibration.

  Accordingly, an object of the present invention is to provide a clamp for mounting on a T-stud, which does not present a problem of extraordinary molding and which makes it possible to securely fasten the clamp on the T-bolt. of its aspects, the present invention relates to a clamp comprising a base, a slot made in this base to allow

  mount the clamp by sliding on a T-bolt and lock element

  it is secured to the base which can be hooked on it when the clamp is slidably mounted on the stud to close the end of the slot and

  to then oppose the release of the clamp of the stud.

  According to a preferred embodiment, the present invention relates to a clamp intended to be fixed on a T-bolt consisting of a head and a rod, the clamp comprising a base having a lower face and a lateral face, a first locking member provided on the base, a

  slot in the underside and extended into the side

  and a shoulder extending along one side of the slot in a plane substantially parallel to the underside of the clamp allowing, when it is put in place, to slide the base on the stud bolt so that this

  shoulder is located below the stud head and a latch element

  elastic belt which can be placed in a position in which it closes the

  slot of the slot, said locking member comprising a second member

  locking adapted to cooperate with the first locking member on the em-

  base of the clamp to close the end of the slot and to prevent separation

  ration between the clip and the stud. Preferably, the locking element

  is integral with the base and can be in the form of an articulated arm

elastically on the base.

  The slot can penetrate only partially in the depth of

  the collet base where it can penetrate through the entire thickness of the

  the base. If the slot penetrates through the entire depth of the base, the locking member may comprise a protruding abutment

  able to penetrate the slot when the first and second ver-

  rust co-operate and then come into abutment against the head of the stud.

  The first locking member may be constituted by a step

  hollowed out in the lateral face of the base while the second

  may be constituted by a hook provided on the locking element

  lage. The shoulder may be tilted so that the stud head compresses the shoulder as the clip is slidably mounted on the stud to provide a vibration-free and / or vibration-free connection between the clip and the stud. An embodiment of the present invention is hereinafter described by way of example with reference to the accompanying drawings, in which: - Figure 1 is a side view of a clamp according to the present invention beside a T-stud welded to a support panel;

  FIG. 2 is a side view of the clip shown in FIG.

  Figure 1 is a perspective view of the clip shown in Figures 1 and 2; - Figure 4 is a view along the line IV-IV of Figure 1; and

  FIG. 5 is a side view, partly in section, representing

  both the clamp mounted on the T-stud and tightening a cable.

  Clamp is indicated generally in the drawings by reference numeral 10.

  The clip 10 is made of a synthetic plastic material, preferably made by injection molding. The preferred material constituting the clip is a

  acetal resin but it is possible to envisage the use of any kind

  plastic material with the required strength and elasticity.

  Lapnce 10 comprises a base 11 and a locking element 12

  having in the form of an arm connected to the base by a hinge 13.

  The base 11 has a lower face 14, an upper face 15 and an end face 16. A slot 17 is formed in the base 11 to penetrate through the entire depth of the base. One end of the slot 17 opens outwardly from the side face 16 while the other end ends inside the base. A shoulder 18 extends on either side of the slot 17, this shoulder 18 lying in a plane substantially

  parallel to the lower face 14. The end face 16 of the base is evident

  to clear a step 19 and the upper surface of the step 19 is bevel-

  to form a profiled cam face 20.

  The locking element 12 is located above the base 11 and comprises a locking member in the form of a hook 21 adapted to hook under the step 19 to secure the locking element 12 on the base It and thereby close the end of the slot 17. The bottom surface of the

  hook 21 is chamfered to form a profiled cam face 22 apt to ve-

  nier in contact with the profiled face 20 and slide on it. The locking member 12 further comprises a cable-receiving portion 23 and a stopper 24, the latter being shaped and positioned to enter the slot 17 when the locking member is hooked on the base i1. The clamp 10 is intended to be mounted on a T-bolt 30 consisting of a head 31 and a rod 32, which is welded to a support panel 33. In order to mount the clamp on the stud 30, the clip on the support panel 33 and slide it in the direction of the arrow A of FIG.

  so that the rod 32 of the stud enters the slot 17 and passes along it

  ci, the surface 18 of the shoulder being located below the head 31 of the stud. When the clamp 10 is pushed all the way against the stud 30 until the head 31 abuts against the end of the slot, the locking element 12 is pressed to push it down on the 11. The inclined profiled faces 20 and 21, provided on the base 11 and the hook 21 respectively, allow the hook to pass on the profiled face 22 to

  come to hang behind step 19 to subjugate the element of ver-

  12 in the base 11. In this position, the stop 24 of the locking element 12 is inside the slot 17, behind the head 31 of the stud, to prevent movement of the clamp relative to the stud. The clamp is then securely mounted on the stud 30 and a cable 40 can be introduced into the cable receiving portion 23 to secure the cable to the panel.

support 33.

  If it is necessary to separate the clamp from the stud ,. we can do it

  without difficulty in raising and turning the locking element 12 suf-

  to clear the hook 21 of the step 19 of the base 11. Once the locking element is cleared and away from the base 11, it is possible to separate the

pinch the stud by sliding it.

  If necessary, the shoulder 18 of the base 11 can be inclined upwards, away from the end face 16 of the base, so that the head of the stud compresses the shoulder 18 when the clamp is slidably mounted on the stud to thereby provide a vibration-free connection between the clamp and the stud. It may further be envisaged to give the slot 17 the shape of a keyhole to force the rod 32 to pass through a narrowed portion of the slot to allow, once the rod is in position at the end of the slot,

  adjust the position of the clamp relative to the stud to ensure a certain

  tain limited game allowing to adjust the position of the clamp on the panel of

support 33.

  The clip 10 can be designed, of course, for object attachment other cables on the support panel, for example the locking element can be made to cooperate with a molding or a trim

  padded in a well-known classical manner.

  The locking mode of the locking element 12 on the base It may further be modified to adapt it to the determined requirements of a particular application. For example, the cooperating locking members of the element of

  locking and the base can be provided on one or both sides

  the base and the locking element.

  It goes without saying that many modifications can be made to the shape and construction of the clip that has just been described without

  as far beyond the scope of the present invention.
