Abstract
Description
L'invention est relative à une canne télescopique de liaison d'une sellette de remorquage à une attache d'un câble d'un téléski, comprenant deux éléments tubulaires allongés emboués télescopiquement, un embout de fixation de la sellette assujetti à l'extrémité inférieure de l'élément tubulaire externe par embotte- ment et expansion d'une partie expansible, un embout annulaire de guidage traversé à coulissement par ltélément tubulaire interne et assujetti à l'extrémité supérieure de l'élément tubulaire externe et un ressort sollicitant les éléments télescopiques en position raccourcie de la canne. The invention relates to a telescopic rod for connecting a towing harness to a cable tie for a ski lift, comprising two elongated tubular elements telescopically buried, a harness fixing attachment subject to the lower end of the external tubular element by embedding and expanding an expandable part, an annular guide end piece slidably traversed by the internal tubular element and secured to the upper end of the external tubular element and a spring biasing the telescopic elements in the shortened position of the rod.
Le brevet français NO 2.303.692 décrit un canne du genre mentionné, dans laquelle la sellette est fixée par un embout embossé et coincé dans l'extrémité inférieure de l'un des éléments tubulaires. La fixation par des doigts crantés, qui s'incrustent dans la paroi du tube, est difficile à mettre en oeuvre et un démontage ultérieur est souvent impossible, les doigts crantés restant ancrés au tube. Le système de fixation du ressort de cette canne connue ne donne pas entière satisfaction. French patent NO 2,303,692 describes a rod of the kind mentioned, in which the harness is fixed by an embossed endpiece and wedged in the lower end of one of the tubular elements. The fixing by notched fingers, which are encrusted in the wall of the tube, is difficult to implement and a subsequent disassembly is often impossible, the notched fingers remaining anchored to the tube. The spring fixing system of this known rod is not entirely satisfactory.
La présente invention a pour but de remédier à ces inconvénients. The present invention aims to remedy these drawbacks.
La canne télescopique selon la présente invention est caractérisée par le fait que ladite partie expansible comporte deux douilles tubulaires tronquées de section légèrement inférieure à la section interne de l'élément tubulaire externe pour permettre un embottement à faible jeu, les faces tronquées desdites douilles étant accolées en position montée de l'embout et des moyens de serrage desdites douilles provoquant une translation relative desdites douilles dans la direction des faces tronquées et un décalage latéral de l'une des douilles par rapport à l'autre pour réaliser un effet de coincement contre la paroi interne de l'élément tubulaire. The telescopic rod according to the present invention is characterized in that said expandable part comprises two truncated tubular sockets of section slightly smaller than the internal section of the external tubular element to allow a low clearance flotation, the truncated faces of said sockets being joined in the mounted position of the end piece and of the clamping means of said sockets causing a relative translation of said sockets in the direction of the truncated faces and a lateral offset of one of the sockets relative to the other to achieve a wedging effect against the inner wall of the tubular element.
Les douilles sont enfilées sur une vis de serrage et en position desserrée cet ensemble peut etre facilement inséré ou retiré en un seul bloc de l'élément tubulaire. Lors du serrage de la vis, les faces tronquées des douilles imposent un glissement latéral des douilles, qui se désaxent et se coincent contre la paroi interne de l'élément tubulaire pour former un ancrage dans lequel se visse la vis de fixation de la sellette. The sockets are threaded on a clamping screw and in the loosened position this assembly can be easily inserted or removed in a single block from the tubular element. When tightening the screw, the truncated faces of the sockets impose a lateral sliding of the sockets, which are offset and jammed against the internal wall of the tubular element to form an anchor in which the fixing screw of the harness is screwed.
L'embout de fixation comporte avantageusement trois douilles fronquées, enfilées sur la vis de serrage, la douille in termédiaire, à double face tronquée, ayant un alésage de diamètre supérieur à celui de la vis pour permettre le décalage latéral lors du serrage. Les faces tronquées forment un coin de préférence dissymétrique. The fixing end piece advantageously comprises three gathered sockets, threaded onto the clamping screw, the intermediate bush, with double truncated face, having a bore of diameter greater than that of the screw to allow lateral offset during tightening. The truncated faces form a wedge, preferably asymmetrical.
Selon un développement de l'invenion, le ressort est emboité sur une tête d'ancrage fixée par une goupille à la douille adjacente, et la tête de la vis de serrage présente un anneau de fixation de la sellette. La surface externe des douilles est mole tés pour accroître l'adhérence au tube. According to a development of the invention, the spring is fitted onto an anchoring head fixed by a pin to the adjacent bushing, and the head of the clamping screw has a ring for fixing the harness. The outer surface of the sockets is mole ted to increase adhesion to the tube.
D'autres avantages et caractéristiques de l'invention ressortiront plus clairement de l'exposé qui va suivre d'un mode de mise en oeuvre de l'invention donné à titre d'exemple non limitatif et représenté aux dessins annexés, dans lesquels
la figure 1 est une vue schématique partiellement arrachée d'une canne selon l'invention;
la figure 2 est une vue en coupe, à échelle agrandie, de la partie inférieure de la canne selon la figure 1;
la figure 3 est une vue éclatée de l'embout de fixation représenté à la figure 2.Other advantages and characteristics of the invention will emerge more clearly from the description which follows of an embodiment of the invention given by way of nonlimiting example and shown in the appended drawings, in which
Figure 1 is a schematic partially cutaway view of a cane according to the invention;
Figure 2 is a sectional view, on an enlarged scale, of the lower part of the rod according to Figure 1;
FIG. 3 is an exploded view of the fixing end piece shown in FIG. 2.
Sur les figures, une canne télescopique 10 comporte un tube extérieur 12, notamment en duralumin, dont la partie inférieure 14 incurvée est obturée par un embout 16 de fixation d'une sellette 18. Dans la partie supérieure 20 du tube 12 est emboîté télescopiquement un tube interne 22, portant à l'extrémité inférieure un piston 24, coopérant avec la paroi interne du tube 12 et à l'extrémité supérieure une articulation 26. Un ressort de traction 28 s'étend à l'intérieur de la canne 10 et est ancré à l'embout 16 et à l'articulation 26, de manière à solliciter la canne télescopique en position raccourcie. Cette canne est décrite dans le brevet précité, auquel on se rapportera pour de plus amples détails, notamment sur la partie supérieure, qui est identique à celle décrite dans ce brevet. In the figures, a telescopic rod 10 comprises an outer tube 12, in particular made of duralumin, the curved lower part 14 of which is closed off by a nozzle 16 for fixing a fifth wheel 18. In the upper part 20 of the tube 12 is telescopically fitted a internal tube 22, carrying at the lower end a piston 24, cooperating with the internal wall of the tube 12 and at the upper end an articulation 26. A tension spring 28 extends inside the rod 10 and is anchored to the nozzle 16 and to the articulation 26, so as to urge the telescopic rod in the shortened position. This rod is described in the aforementioned patent, to which reference will be made for further details, in particular on the upper part, which is identical to that described in this patent.
En se référant plus particulièrement aux figures 2 et 3, on voit que l'embout 16 de fixation de la sellette 18 comporte une vis 30, sur laquelle sont enfilées en position montée successivement trois douilles 32, 34, 36. La douille 32, adjacente à la tête 38 de la vis 30, présente un collet 40 venant en position in sérée de l'embout 16 en appui de l'extrémité du tube 14 et limitant la pénétration de la douille 32 dans le tube 14. La partie emboîtée de la douille 32 et les douilles 34, 36 ont un diamètre With particular reference to FIGS. 2 and 3, it can be seen that the end piece 16 for fixing the fifth wheel 18 comprises a screw 30, on which three sockets 32, 34, 36 are threaded in successively mounted position. The socket 32, adjacent at the head 38 of the screw 30, has a collar 40 coming into the inserted position of the endpiece 16 bearing on the end of the tube 14 and limiting the penetration of the socket 32 in the tube 14. The nested part of the socket 32 and sockets 34, 36 have a diameter
