Abstract

The immobilizing device uses a part comprising two U-shaped parts (11) able to go astride the rod. These two parts are joined in their upper rectilinear parts (12) and comprise means for immobilizing a standard nut allowing the fixing of the part and the rod by a screw.

Description

La présente invention est relative à un dispositif pour immobiliser une tringle pivotante selon son axe. The present invention relates to a device for immobilizing a pivoting rod along its axis.

Le problème d'une telle immobilisation se pose tout particulièrement à propos des barrières à cornadis. Sur une telle barrière, la tringle pivotante est maintenue au-dessus du longeron supérieur au moyen de paliers, pourvus de jambes de fixation, dans lesquels ladite tringle est engagée axialement. De préférence, l'immobilisation s'effectue au niveau d'un palier situé à l'extrémité de la barrière. The problem of such immobilization arises particularly with regard to the gates of the locks. On such a barrier, the pivoting rod is held above the upper spar by means of bearings, provided with fixing legs, in which said rod is engaged axially. Preferably, immobilization takes place at a level located at the end of the barrier.

Selon la technique actuelle, cette immobilisation s'effectue au moyen de deux manchons tubulaires disposés chacun de part et d'autre du palier, chaque manchon comportant un moyen permettant de le solidariser sur la tringle. Pour atteindre ce résultat, on soude un écrou du commerce sur chaque manchon ce qui permet, en perçant convenablement le manchon, de l'immobiliser à l'aide d'une vis adaptée. According to the current technique, this immobilization is carried out by means of two tubular sleeves each disposed on either side of the bearing, each sleeve comprising a means making it possible to secure it to the rod. To achieve this result, a commercial nut is welded onto each sleeve, which allows it to be appropriately pierced to immobilize it using a suitable screw.

Cette technique est relativement coûteuse puisqu'elle nécessite, notamment, le soudage de deux écrous et la rectification des filetages desdits écrous après le traitement anticorrosion (galvanisation). A cela s'ajoute le fait que l'un des manchons doit comporter des moyens pour limiter la rotation de la tringle. Ces moyens sont généralement constitués par deux doigts soudés sur le manchon et s'étendant, au-delà de l'une des extrémités de ce dernier, sur le palier et contre l'une ou l'autre des jambes duquel peut prendre appui le doigt correspondant. This technique is relatively expensive since it requires, in particular, the welding of two nuts and the rectification of the threads of said nuts after the anticorrosion treatment (galvanization). To this is added the fact that one of the sleeves must include means for limiting the rotation of the rod. These means generally consist of two fingers welded to the sleeve and extending, beyond one of the ends of the latter, on the bearing and against one or the other of the legs of which the finger can bear. corresponding.

II ressort des explications ci-dessus, que l'immobilisation de la tringle nécessite la réalisation et l'utilisation de deux pièces distinctes et coûteuses et de deux vis dont l'une doit être adaptée pour permettre la commande en rotation de la tringle. It follows from the above explanations that immobilization of the rod requires the production and use of two separate and expensive parts and two screws, one of which must be adapted to allow the rod to be controlled in rotation.

La présente invention, qui remédie à ces inconvénients, est remarquable en ce que l'immobilisation de la tringle est réalisée par une pièce unique, obtenue par pliage d'une tige métallique rigide, comportant deux parties en forme d'U dont les branches sont réunies, deux à deux, par une partie rectiligne maintenant entre lesdites parties en forme d'U une distance supérieure à la longueur du palier et dont la distance entre les branches est au moins égale au diamètre de ladite tringle, des moyens étant prévus pour bloquer cette pièce sur cette dernière. The present invention, which overcomes these drawbacks, is remarkable in that the immobilization of the rod is achieved by a single piece, obtained by folding a rigid metal rod, comprising two U-shaped parts whose branches are joined, two by two, by a rectilinear part maintaining between said U-shaped parts a distance greater than the length of the bearing and the distance between the branches of which is at least equal to the diameter of said rod, means being provided for blocking this piece on the latter.

La présente invention sera mieux comprise par la description qui va suivre faite en se référant aux dessins annexés à titre d'exemple indicatif, seulement, sur lesquels -la figure 1 est une vue en élévation montrant un dispositif connu ; -la figure 2 est une vue en coupe effectuée selon la ligne II-II de la figure 1 ; -la figure 3 est une vue en élévation de la pièce de l'invention ; -la figure 4 est la vue de gauche de la figure 3; -la figure 5 est la vue de dessus de la figure 3 ; -la figure 6 est une vue analogue à celle 3 montrant la mise en oeuvre du dispositif de l'invention; -la figure 7 est une vue selon la flèche F de la figure 6, montrant l'immobilisation de la tringle. The present invention will be better understood from the description which follows, made with reference to the accompanying drawings by way of indicative example only, in which - Figure 1 is an elevation view showing a known device; FIG 2 is a sectional view taken along line II-II of Figure 1; FIG. 3 is an elevation view of the part of the invention; FIG 4 is the left view of Figure 3; FIG. 5 is the top view of FIG. 3; FIG 6 is a view similar to that 3 showing the implementation of the device of the invention; FIG. 7 is a view along arrow F in FIG. 6, showing the immobilization of the rod.

En se reportant aux figures 1 et 2, on voit que le problème consiste à immobiliser, axialement, une tringle 1 par rapport à un palier 2 relié à un longeron 3 par l'entremise de jambes 4. Selon la technique connue, on utilise deux manchons 5 et 6, pouvant être disposés sur la tringle 1 de part et d'autre du palier 2 et immobilisés sur ladite tringle. A cet effet, chaque manchon comporte un écrou 7, du commerce, soudé sur ledit manchon qui est convenablement percé pour permettre à une vis, schématisée en 8, de prendre appui contre ladite tringle. Referring to Figures 1 and 2, we see that the problem is to immobilize, axially, a rod 1 relative to a bearing 2 connected to a beam 3 via legs 4. According to the known technique, two are used sleeves 5 and 6, which can be arranged on the rod 1 on either side of the bearing 2 and immobilized on said rod. To this end, each sleeve comprises a commercial nut 7, welded to said sleeve which is suitably drilled to allow a screw, shown diagrammatically at 8, to bear against said rod.

Lorsque les deux manchons sont en place, la tringle est immobilisée axialement, mais elle peut pivoter librement. Pour certaines applications, il est souhaitable de limiter la rotation de la tringle 1. Selon la technique connue, le manchon 5 comporte deux doigts 9 s'étendant au-dessus du palier 2. When the two sleeves are in place, the rod is immobilized axially, but it can pivot freely. For certain applications, it is desirable to limit the rotation of the rod 1. According to the known technique, the sleeve 5 comprises two fingers 9 extending above the bearing 2.

Lorsque le manchon est bloqué sur la tringle, il est possible de faire pivoter cette dernière jusqu'à ce que l'un ou l'autre des doigts vienne prendre appui contre la jambe 4 correspondante comme montré sur la figure 2. When the sleeve is blocked on the rod, it is possible to pivot the latter until one or the other of the fingers comes to bear against the corresponding leg 4 as shown in FIG. 2.

Selon la présente invention, les manchons 5 et 6 sont remplacés par une pièce unique, référencée 10, telle que montrée en regard des figures 3 à 5. According to the present invention, the sleeves 5 and 6 are replaced by a single piece, referenced 10, as shown with reference to FIGS. 3 to 5.

La pièce 10 comporte deux parties, sensiblement, identiques 11 affectant chacune la forme d'un U dont la distance entre les branches est supérieure au diamètre de la tringle 1. The part 10 has two substantially identical parts 11 each having the shape of a U, the distance between the branches of which is greater than the diameter of the rod 1.

Les deux étriers 11 sont réunis, à leur partie supérieure, par une partie rectiligne 12 ménageant entre ces derniers un espace supérieur à la longueur du palier. Comme, de préférence, la pièce 10 est réalisée en une seule pièce obtenue à partir d'un fil rigide convenablement plié, l'une des parties 12 n'est pas forcément reliée aux deux étriers. Selon l'invention, des moyens sont prévus sur la pièce 10 pour permettre la mise en oeuvre d'un dispositif de blocage. The two stirrups 11 are joined, at their upper part, by a rectilinear part 12 leaving between them a space greater than the length of the bearing. As, preferably, the part 10 is produced in a single part obtained from a rigid wire suitably bent, one of the parts 12 is not necessarily connected to the two stirrups. According to the invention, means are provided on the part 10 to allow the implementation of a blocking device.

A cet effet, il est prévu un étrier 13 soudé à l'une des extrémités de la pièce 10 entre les parties 12 et présentant sur sa partie médiane un orifice 14 de passage d'une vis 15 pouvant se visser dans un écrou 16 du commerce, immobilisé sur plat en rotation entre les branches dudit étrier 13. Comme l'écrou 16 est totalement indépendant de la pièce 10 il n'est nullement affecté par les traitements auxquels cette dernière est soumise (galvanisation par exemple). For this purpose, there is provided a stirrup 13 welded at one end of the part 10 between the parts 12 and having on its central part an orifice 14 for the passage of a screw 15 which can be screwed into a nut 16 on the market. , immobilized on a rotating plate between the branches of said stirrup 13. As the nut 16 is completely independent of the part 10, it is in no way affected by the treatments to which the latter is subjected (galvanization for example).

Préalablement à l'introduction de la tringle 1 dans le palier 2, on dispose la pièce 10 comme montré sur la figure 6, puis on engage ladite tringle dans l'ensemble et on la pousse jusqu'à ce que son extrémité vienne occuper la position montrée en traits mixtes. A ce moment, on glisse l'écrou 16 entre la partie supérieure de la tringle 1 et la partie médiane de l'étrier 13, on engage la vis 15 dans ce dernier et on visse jusqu'à ce que l'extrémité de ladite vis prenne fermement appui contre ladite tringle. Prior to the introduction of the rod 1 into the bearing 2, we have the part 10 as shown in Figure 6, then we engage said rod in the assembly and we push it until its end comes to occupy the position shown in phantom. At this moment, we slide the nut 16 between the upper part of the rod 1 and the middle part of the stirrup 13, we engage the screw 15 in the latter and we screw until the end of said screw firmly bear against said rod.

En utilisant la tête 17 de la vis de blocage, il est possible de faire pivoter la tringle 1, la rotation de cette dernière étant limitée par les parties 12 qui prennent appui contre les jambes 4. By using the head 17 of the locking screw, it is possible to pivot the rod 1, the rotation of the latter being limited by the parts 12 which bear against the legs 4.

Selon un autre mode de réalisation de l'invention, l'écrou 16 peut être soudé directement soit sur la pièce 10 soit sur l'étrier 13. Ce mode de réalisation est applicable dans le cas ou l'ensemble n'est pas soumis à un traitement de protection par galvanoplastie.According to another embodiment of the invention, the nut 16 can be welded directly either to the part 10 or to the stirrup 13. This embodiment is applicable in the case where the assembly is not subjected to protective treatment by electroplating.
