Description

l'invention concerne un corps en caoutchouc ou en matière synthétique qui se compose d'une partie intermédiaire élastique et de deux plaques de fixation qui y adhèrent et qui sont reliées par elle. the invention relates to a rubber or synthetic body which consists of an elastic intermediate part and two fixing plates which adhere to it and which are connected by it.

Dans les pièces en caoutchouc-métal de ce genre déjà connues, l'adhérence du corps élastique de caoutchouc aux deux plaques de métal est obtenue par pré-traitement approprié des parties métalliques et vulcanisation du caoutchouc ou par un procédé de collage chimique. De telles pièces en caoutchoucmétal trouvent de multiples applications dans la construction des machines. les éléments de la machine qui sont fixés aux parties métalliques sollicitent le corps de caoutchouc, suivant le mode d'emploi, à la compression, au cisaillement, à la traction ou à une combinaison de ces types de contraintes. En cas d'efforts excessifs ou dans d'autres conditions défavorables, il peut arriver que le caoutchouc s'arrache des zones d'adhérence des plaques de fixation ou que le corps de caoutchouc luimeme soit rompu.Il peut en résulter des dommages graves aux machines ou même, dans le cas d'appareils de sport, des accidents humains. In rubber-metal parts of this kind already known, the adhesion of the elastic rubber body to the two metal plates is obtained by appropriate pre-treatment of the metal parts and vulcanization of the rubber or by a chemical bonding process. Such rubber-metal parts find multiple applications in machine construction. the elements of the machine which are fixed to the metal parts stress the rubber body, according to the instructions for use, compression, shearing, traction or a combination of these types of stresses. In the event of excessive effort or in other unfavorable conditions, it may happen that the rubber tears off from the areas of adhesion of the fixing plates or that the rubber body itself is broken, which may result in serious damage to the machines or even, in the case of sports equipment, human accidents.

le brevet suisse no 573 065 décrit un tampon amortisseur aui est destiné à être sollicité exclusivement à la compression et qui comporte, non pas deux plaques, mais seulement un socle. Swiss Patent No. 573,065 describes a shock absorbing pad which is intended to be used exclusively for compression and which comprises, not two plates, but only a base.

la plaque de métal supérieure fait défaut et, en conséquence, i' n'est pas possible de raccorder un appareil à cet endroit du tampon. le câble oui est disposé à l'intérieur est destiné à empecher les différentes rondelles de tomber.the upper metal plate is missing and, therefore, it is not possible to connect a device to this location of the pad. the yes cable is placed inside is intended to prevent the different washers from falling.

D'après la demande de brevet allemand no 1 919 944, une :arde de caoutchouc est munie, à ses extrémités, de colliers de fixation et une couche de tissu, qui est placée à l'intérieur d'une cavité et qui est également maintenue par un boulon des colliers de fixation, est destinée à protéger la bande élastique contre un allongement excessif. According to German patent application No. 1,919,944, a rubber strap is provided, at its ends, with fixing collars and a layer of fabric, which is placed inside a cavity and which is also held by a bolt of fixing collars, is intended to protect the elastic band against excessive elongation.

L'invention a pour but de prendre des précautions pour que même en cas de rupture de la partie intermédiaire élastique ou lorsqu'elle se détache des zones d'adhérence, commue cela peut se produire par exemple à l'occasion de fortes sollicitations à la traction, il existe une sécurité qui empêche l'endommage- ment des machines ou prévient les accidents humains. The object of the invention is to take precautions so that even in the event of rupture of the elastic intermediate part or when it detaches from the adhesion zones, such as may occur, for example, during heavy stresses on the traction, there is a safety device which prevents damage to machines or prevents human accidents.

L'invention atteint ce but en offrant un corps en caoutchouc ou en matière synthétique du genre défini dans le préambule, dont la nouveauté consiste en ce que les plaques de fixation, destinées au raccordement dlappareils, de machines, d'outils ou d'éléments d'appareils de sports, sont munies d'éléments de fixation qui sont réunis l'un à l'autre par un câble formé de fil d'acier qui n'est pas fixé à la partie intermédiaire élastique.On parvient de la sorte à ce quren cas de rupture de la partie intermédiaire élastique ou lorsqu'elle se détache des zones d'adhérence, cette partie perd certes son efficacité, mais le câble peut la remplacer à titre de secours pendant une brève période, jusqutà ce que les machines concernées soient arrêtées ou qu'en cas d'utilisation du corps en caoutchouc ou en matière synthétique pour des appareils de sports, l'homme soit en sécurité. The invention achieves this aim by providing a rubber or synthetic body of the kind defined in the preamble, the novelty of which is that the fixing plates, intended for the connection of apparatus, machines, tools or elements sports equipment, are provided with fastening elements which are joined to each other by a cable formed of steel wire which is not fixed to the elastic intermediate part. What if the elastic intermediate part breaks or when it comes off from the adhesion zones, this part certainly loses its effectiveness, but the cable can replace it as a backup for a short period, until the machines concerned are stopped or that if the rubber or synthetic body is used for sports equipment, the man is safe.

L'invention prévoit en outre que le câble soit plus long que la plus courte distance entre les deux plaques de fixation à l'état non sollicité de la partie intermédiaire. On peut avantageusement donner à la longueur du cable souple une dimension telle que la limite d'élasticité de la partie intermédiaire élastique sollicitée par des forces intenses ne soit pas dépassée et que le câble tendu empeche de telles sollicitations excessives et protège ainsi à titre préventif la partie élastique contre sa rupture ou contre sa séparation des plaques de fixation.  The invention further provides that the cable is longer than the shortest distance between the two fixing plates in the non-stressed state of the intermediate part. It is advantageous to give the length of the flexible cable a dimension such that the elastic limit of the elastic intermediate part stressed by intense forces is not exceeded and that the stretched cable prevents such excessive stresses and thus protects as a precaution the elastic part against breaking or against its separation from the fixing plates.

Enfin, il est encore prévu, dans le cadre de l'invention, que le câble soit engainé d'un tube flexible. On évite ainsi que le corps élastique soit endommagé par frottement du câble. Finally, it is also provided, within the framework of the invention, for the cable to be sheathed with a flexible tube. This prevents the elastic body from being damaged by friction of the cable.

Les dessins illustrent lZinvention au moyen de deux exemples de réalisation. The drawings illustrate the invention by means of two embodiments.

La fig. 1 est une vue en coupe longitudinale du corps en caoutchouc ou en matière synthétique suivant l'invention. Fig. 1 is a view in longitudinal section of the rubber or plastic body according to the invention.

La fig. 2 est une vue en coupe longitudinale du corps en caoutchouc ou en matière synthétique, sous une forme de réalisation modifiée par rapport à celle de la fig. 1. Fig. 2 is a view in longitudinal section of the rubber or synthetic material body, in an embodiment modified from that of FIG. 1.

D'après la fig. 1, le corps en caoutchouc ou en matière synthétique 1 présente une forme cylindrique avec une surface latérale arquée vers l'intérieur. Des plaques rigides de fixation supérieure et inférieure 9 et 4 adhèrent par leurs faces inférieures et leurs bords à une partie intermédiaire 2 faite de caoutchouc naturel, de caoutchouc synthétique ou de matière synthétique élastique, l'aihérence pouvant être obtenue par un pré-traitement approprié des plaques 3, 4 et par une vulcanisation commune avec la partie intermédiaire 2 ou par traitement chimique et collage de tous les éléments entre eux.Les plaques 3 et 4 sont munies d'éléments de raccordement 5et 6 du genre écrou, pour le raccordenent d'appareils, machines, outils ou éléments d'appareils de sports de tous genres. les éléments de fixation 5 et 6 sont reliés l'un à l'autre par un câble flexible 7 qui est fait de fil d'acier ou d'autres matériaux appropriés et qui est plus long que la distance des surfaces d'extrémité opposées 8 et 9 des éléments Ide raccordement 5 et 6, c'est-à-dire que le câble est détendu tant que la partie intermédiaire 2 n'est pas fortement sollicitée à la traction. La longueur du câble 7 est opportunément choisie de telle manière qu'il ne se raidisse qu'au cas où, sous l'effet de sollicitations à la traction, la partie intermédiaire 2 est étirée élastiquement au point que sa limite d'élasticité est atteinte et qu'elle est menacée de rupture. According to fig. 1, the rubber or synthetic body 1 has a cylindrical shape with a side surface arched inward. Rigid upper and lower fixing plates 9 and 4 adhere by their lower faces and their edges to an intermediate part 2 made of natural rubber, synthetic rubber or elastic synthetic material, the adhesion being obtainable by an appropriate pretreatment plates 3, 4 and by a common vulcanization with the intermediate part 2 or by chemical treatment and bonding of all the elements together. The plates 3 and 4 are provided with connection elements 5 and 6 of the nut type, for the connection of apparatus, machines, tools or parts of sports apparatus of all kinds. the fasteners 5 and 6 are connected to each other by a flexible cable 7 which is made of steel wire or other suitable material and which is longer than the distance from the opposite end surfaces 8 and 9 of the connection elements 5 and 6, that is to say that the cable is relaxed as long as the intermediate part 2 is not highly stressed in traction. The length of the cable 7 is suitably chosen in such a way that it only stiffens in the event that, under the effect of tensile stresses, the intermediate part 2 is stretched elastically to the point that its elastic limit is reached. and that she is threatened with rupture.

D'après la fig. 2, sur laquelle la forme de réalisation du corps en caoutchouc ou en matière synthétique 1 correspond quant au reste à celle de la fig. 1, il est tendu, sur le câble 7, un tube flexible 10 qui est fabriqué en une matière résistante à l'usure par frottement et qui protège la partie intermédiaire 2 contre l'endormagement dû au câble 7. Par ailleurs, au lieu d'être réalisée sous forme cylindrique, la partie intermédiaire 2 peut aussi présenter une section carrée ou rectangulaire.  According to fig. 2, on which the embodiment of the rubber or synthetic body 1 corresponds as for the rest to that of FIG. 1, there is stretched, on the cable 7, a flexible tube 10 which is made of a material resistant to wear by friction and which protects the intermediate part 2 against the falling asleep due to the cable 7. Furthermore, instead of 'be made in cylindrical form, the intermediate part 2 may also have a square or rectangular section.
