Abstract

Interlocking rod 1 intended for anchoring fasteners to support elements provided with a retaining plate 3, the said retaining plate being produced from the same plastic as the support elements, the interlocking shank 1 being embedded in the retention plate 3, the whole thing being welded by rotation under pressure onto the support elements. In order to fasten the interlocking shank 1 via the retention plate 3 onto the support elements 14, the insertion shank 1 is equipped at its end with a tapered shoulder 2 which is inserted into a tapered recess 4 formed opposite it in the retention plate 3 under conditions such that it cannot rotate.

Description

La présente invention concerne une tige d'emmanchement munie d'une plaquette de retenue pour 1' ancrage d'organes de fixation sur des éléments support, la plaquette de retenue et l'élément support étant en l'occurrence réalisés dans la même matière plastique et la tige d'emmanchement étant en l'occurrence encastrée dans la plaquette de retenue et soudée avec cette plaquette sur l'élément support par frottement de contact en rotation sous pression. Cette tige d'emmanchement, dont le fût peut avoir une configuration dirente suivant lfutilisation qui en est faite, est habituellement réalisée dans une matière difirente de celle de la plaquette de retenue. The present invention relates to a fitting rod provided with a retaining plate for anchoring fastening members on support elements, the retaining plate and the support element being in this case made of the same plastic material. and the fitting rod being in this case embedded in the retaining plate and welded with this plate on the support element by contact friction in rotation under pressure. This fitting rod, the barrel of which may have a direct configuration depending on the use made of it, is usually made of a material different from that of the retaining plate.

Dans le cas du brevet EP-OS 145 238 par exemple, qui est réputé correspondre a l'état actuel de la technique dans ce domaine, le fût de la tige d'emmanchement est muni de nervures en forme de disques minces qui font saillie de tous côtes et qui, une fois la tige d'emmanchement introduite dans le trou de fixation de l'élément à maintenir en position, commencent par se resserrer quelque peu pour se redéployer ensuite une fois le trou traversé, exerçant ainsi en arrière de celui-ci un solide effort de cramponnage et ceci quelle que soit l'épaisseur de paroi de la pièce a maintenir en position.La tige d'emmanchement se trouve encastré par sa plaquette de pied dans un évidement de la plaquette de retenue dans des conditions telles que le fût peut être déplacé latéralement et donc ajusté en fonction de la position exacte du trou de fixation, lorsque la plaquette de retenue est soudée sur l'élé- ment porteur. In the case of patent EP-OS 145 238 for example, which is deemed to correspond to the current state of the art in this field, the barrel of the fitting rod is provided with ribs in the form of thin disks which project from all ribs and which, once the fitting rod is inserted into the fixing hole of the element to be held in position, begin to tighten somewhat and then redeploy once the hole is crossed, thus exerting behind it ci a solid clamping effort and this whatever the wall thickness of the part to be held in position. The fitting rod is embedded by its foot plate in a recess of the retaining plate under conditions such as the barrel can be moved laterally and therefore adjusted according to the exact position of the fixing hole, when the retaining plate is welded to the support element.

La présente invention propose une solution qui doit permettre d'éviter cette aptitude de la tige d'emmanchement à se déplacer latéralement et qui est une particularité justement voulue par cet état actuel de la technique, car il s'agit en l'occurrence de fixer localement sur l'élément porteur une tige d'emmanchement, et en particulier de ce que l'on désigne sous l'appellation de tige filetée, pour fixer sur celle-ci par exem ple des serre-câbles comportant des orifices d'emmanchement en correspondance.  The present invention proposes a solution which must make it possible to avoid this ability of the fitting rod to move laterally and which is a characteristic precisely desired by this current state of the art, since it is a question here of fixing locally on the carrier element a fitting rod, and in particular of what is designated by the name of threaded rod, for fixing thereon for example cable clamps having fitting holes in correspondence.

Cet objectif se trouve en l'occurrence réalisé suivant l'invention par le fait que la plaquette de pied de la tige d'emmanchement comporte un épaulement allant en s'évasant suivant un tracé conique, qui s'introduit dans un évidement de forme conique ménagé en correspondance dans la plaquette de retenue et qui se fixe sur celle-ci dans des conditions telles qu'il ne puisse tourner. Une telle disposition permet donc de faire de la tige d'emmanchement et de la plaquette de retenue un ensemble monobloc que l'on peut ensuite souder sur l'élé- ment porteur par la technique éprouvée de frottement de contact en rotation sous pression. This objective is found in this case achieved according to the invention by the fact that the foot plate of the fitting rod has a shoulder which widens along a conical path, which is introduced into a recess of conical shape. arranged in correspondence in the retaining plate and which is fixed thereon in conditions such that it cannot rotate. Such an arrangement therefore makes it possible to make the fitting rod and the retaining plate into a one-piece assembly which can then be welded to the carrier element by the proven technique of contact friction in rotation under pressure.

Pour encastrer le pied de la tige d'emmanchement dans l'évidement conique de la plaquette de retenue de façon à l'empêcher de tourner, il est tout indiqué, et ceci constitue une autre particularité de l'invention, que l'épaulement conique comporte sur sa surface extérieure plusieurs arêtes formant saillie et orientées dans le sens de l'axe de la tige d'emmanchement qui, lors de l'introduction de la tige d'emman chement dans la plaquette de retenue viennent s'encastrer dans des rainures ménagées en correspondance dans l'évide- ment conique. To embed the foot of the fitting rod in the conical recess of the retaining plate so as to prevent it from turning, it is indicated, and this constitutes another feature of the invention, that the conical shoulder has on its outer surface several ridges projecting and oriented in the direction of the axis of the fitting rod which, during the introduction of the fitting rod into the retaining plate are embedded in grooves arranged in correspondence in the conical recess.

Pour immobiliser par ailleurs solidement le pied de la tige d'emmanchement dans l'évidement, il est également tout indiqué, et ceci constitue encore une autre particularité de l'invention, de prévoir entre l'épaulement conique et le fût de la tige d'emmanchement une partie cylindrique à laquelle correspond, dans la plaquette de retenue et à l'extrémité de l'évi- dement conique un trou cylindrique de même diamètre intérieur et que cette section cylindrique de la tige d'emmanchement comporte des arêtes formant saillie vers l'extérieur qui, lors de l'emmanchement sous pression de l'épaulement conique dans l'évidement conique, viennent s'accrocher sur le bord extérieur du trou cylindrique. To immobilize the foot of the fitting rod securely in the recess, it is also very suitable, and this constitutes yet another feature of the invention, to provide between the conical shoulder and the barrel of the rod d fitting a cylindrical part to which corresponds, in the retaining plate and at the end of the conical recess, a cylindrical hole of the same internal diameter and that this cylindrical section of the fitting rod has edges projecting towards the outside which, during the press fit of the conical shoulder in the conical recess, comes to hang on the outside edge of the cylindrical hole.

La planche de schémas ci-jointe représente un exemple de configuration de la présente invention, dont nous allons donner dans ce qui suit une description plus détaillée. The attached diagram sheet represents an example configuration of the present invention, which we will give in the following a more detailed description.
