Abstract

The bracket is formed from a rigid metal collar (2) with a plastics material forming a sleeve (3) extending to either side of the metal hook and providing support and protection for the cable. The hook has an attachment hole (2c) at the top and the lip of the hook extends above the protective sleeve to allow a threaded rod (4) to extend between the back and the lip of the hook. A wing nut can be used to tighten the bracket round the sleeve. The sleeve is of 'U' shaped outer profile and has a cylindrical passage (3a) for the cable and a longitudinal top slot (3b) to permit easy cable insertion and removal.

Description

La présente invention concerne un moyen de suspension d'un câble fragile tel qu'un câble coaxial pour télédistribution. The present invention relates to a means of suspending a fragile cable such as a coaxial cable for cable distribution.

Actuellement, on utilise des colliers rigides qui sont munis d'une patte de fixation et qui forment une boucle destinée à enserrer le câble et équipée de moyens de fermeture. Currently, rigid collars are used which are provided with a fixing lug and which form a loop intended to grip the cable and equipped with closing means.

En raison de leur gros diamètre, ces câbles coaxiaux présentent une forte prise au vent et, de ce fait, peuvent être soumis à des oscillations importLltes. I1 en résulte de fréquentes ruptures aux entrées et sorties des colliers. Due to their large diameter, these coaxial cables have a strong wind resistance and, as a result, can be subjected to significant oscillations. I1 results in frequent breaks at the inputs and outputs of the collars.

La présente invention vise à remédier à cet inconvénient. A cet effet, les moyens qu'elle concerne comprennent non seulement un collier rigide du type précité, mais en outre un manchon en matière souple et élastique, dont l'alésage a un diamètre correspondant à celui du câble à suspendre, dont la longueur est supérieure à celle du collier rigide dans la boucle duquel il est engagé et qui est fendu longitudinalement de manier à permettre l'engagemment du câble dans son alésage. The present invention aims to remedy this drawback. To this end, the means which it relates to comprise not only a rigid collar of the aforementioned type, but also a sleeve made of flexible and elastic material, the bore of which has a diameter corresponding to that of the cable to be suspended, the length of which is greater than that of the rigid collar in the loop of which it is engaged and which is split longitudinally so as to allow the engagement of the cable in its bore.

Le débordement de ce manchon de part et d'autre du collier procure à ces moyens de suspension une pression et une raideur dégressive qui diminue considérablement les risques de rupture du câble qui leur est suspendu. The overflow of this sleeve on either side of the collar gives these suspension means pressure and degressive stiffness which considerably reduces the risks of rupture of the cable which is suspended from them.

Ce manchon peut être réalisé en caoutchouc ou similaire. This sleeve can be made of rubber or the like.

I1 faut noter qu'en raison de son coéfficient de frottement élevé par rapport à l'isolant du câble, la prbsence de ce manchon assure la tenue axiale du câble par rapport au collier qui, de ce fait, peut être soit fixé à un poteau, soit lui-mZme suspendu à une console fixée audit poteau. It should be noted that due to its high coefficient of friction with respect to the cable insulation, the presence of this sleeve ensures the axial resistance of the cable with respect to the collar which, therefore, can be fixed to a post , or itself suspended from a console fixed to said post.

Les moyens de fermeture de la boucle du collier peuvent être constitués, de façonconnue, par un boulon dont la vis traverse les deux extrémités de la boucle. The means for closing the loop of the collar may be constituted, in the form of a bolt, the screw of which passes through the two ends of the loop.

Cependant, suivant une forme d'exécution préférée de l'invention, facilitant considérablement la mise en place de ces moyens de suspension, ces moyens de fermeture comprennent un anneau de forme carrée ou rectangulaire, articulé par l'un de ses côtés, à l'extrémité de la boucle du collier solidaire de la patte de fixation et dont le côté opposé est engageable, élastiquement, dans un cran forme sur l'autre extrémité de la boucle, c'est-à-dire son extrémité opposée.However, according to a preferred embodiment of the invention, considerably facilitating the installation of these suspension means, these closing means comprise a ring of square or rectangular shape, articulated by one of its sides, at l end of the loop of the collar secured to the fixing lug and the opposite side of which can be engaged, elastically, in a notch formed on the other end of the loop, that is to say its opposite end.

Ainsi, la fermeture de la boucle du collier, après mise en place du câble dans le manchon, est réalisable instantanément et sans aucun outil. Thus, the closure of the loop of the collar, after placing the cable in the sleeve, can be carried out instantly and without any tool.

Suivant une forme d'exécution simple de l'invention, le palier d'articulation de l'anneau sur l'extrémité considérée de la boucle est constitué par au moins une patte découpée dans ladite extrémité et cintrée sensiblement au profil de la section de l'anneau.  According to a simple embodiment of the invention, the hinge bearing of the ring on the considered end of the loop is constituted by at least one lug cut out in said end and curved substantially to the profile of the cross section of the 'ring.

De toute façon, 1'invention sera bien comprise à l'aide de la description qui suit an référence aux dessins schématiques annexés représentant, à titre d'exemples non limitatifs, deux formes d'exEcution de ces moyens de suspension :
Figure 1 est une vue en perspective illustrant une premiere forme d'exécution de ces moyens de suspension
Figure 2 est une vue similaire à figure 1 illustrant une seconde forme d'exécution de ces moyens de suspension.In any case, the invention will be clearly understood with the aid of the description which follows, with reference to the appended schematic drawings showing, by way of nonlimiting examples, two forms of execution of these suspension means:
Figure 1 is a perspective view illustrating a first embodiment of these suspension means
Figure 2 is a view similar to Figure 1 illustrating a second embodiment of these suspension means.

Comme le montre la figure 1, les moyens de suspension selon l'invention comprennent en combinaison, d'une part, un collier rigide 2 en métal ou matière plastique ou autre et un manchon 3 en matière souple et élastique. As shown in Figure 1, the suspension means according to the invention comprise in combination, on the one hand, a rigid collar 2 of metal or plastic or other material and a sleeve 3 of flexible and elastic material.

Le collier rigide 2 forme une boucle 2a destinée à enserrer le câble à suspendre et dont une extrémité est prolongée par une patte de fixation 2b percée d'un trou 2c pour le passage d'une vis, boulon ou similaire. The rigid collar 2 forms a loop 2a intended to enclose the cable to be suspended and one end of which is extended by a fixing lug 2b pierced with a hole 2c for the passage of a screw, bolt or the like.

Le manchon 3 est d'une longueur tres supérieure à celle du collier 2. De plus il présente , d'une part, un alésage 3a d'un diamètre sensiblement égal à celui du câble à suspendre et, d'autre part, une fente 3b permettant l'engagement dudit câble dans l'alésage li
On conçoit aisément que lorsqu'un câble est suspendu à l'aide de ces moyens, la présence du manchon 3 leur procure vis-à-vis du câble suspendu, une pression et une raideur régressive qui éliminent pratiquement tout risque de rupture du câble ou de sa gaine à I'entrée ou à la sortie du collier rigide 2.The sleeve 3 is of a length much greater than that of the collar 2. In addition it has, on the one hand, a bore 3a with a diameter substantially equal to that of the cable to be suspended and, on the other hand, a slot 3b allowing the engagement of said cable in the bore li
It is easily understood that when a cable is suspended using these means, the presence of the sleeve 3 gives them, with respect to the suspended cable, a pressure and a regressive stiffness which virtually eliminate any risk of cable breakage or of its sheath at the entry or exit of the rigid collar 2.

Dans l'exemple illustré sur la figure i, les moyens de fermeture de la boucle 2a du collier 2 sont constitués par un boulon 4 traversant de part en part les deux extrémités en regard de la boucle 2a et permettant de serrer le manchon 3 et le câble suspendu entre les deux brins de la boucle 2a. In the example illustrated in FIG. I, the means for closing the loop 2a of the collar 2 are constituted by a bolt 4 passing right through the two opposite ends of the loop 2a and making it possible to tighten the sleeve 3 and the cable suspended between the two strands of the loop 2a.

Dans l'exemple illustré sur la figure 2, les moyens de fermeture de la boucle 2a sont constitués par un anneau 5 de forme rectangulaire ou carrée1 articulé par l'un de ses côtés à l'extrémité de la boucle 2a du collier 2 solidaire de la patte de fixation 2b et dont le côté opposé est engageable élastiquement dans un cran 6 ménagé à l'autre extrémité libre de la boucle 2a. On conçoit aisément que la fermeture du collier 2 à l'aide des moyens illustrés sur la figure 2, peut être réalisée de façon beaucoup plus rapide qu'a l'aide de ceux illustrés sur la figure 1. In the example illustrated in FIG. 2, the means for closing the loop 2a consist of a ring 5 of rectangular or square shape1 articulated by one of its sides at the end of the loop 2a of the collar 2 secured to the fixing lug 2b and the opposite side of which can be engaged elastically in a notch 6 formed at the other free end of the loop 2a. It is easily understood that the closure of the collar 2 using the means illustrated in FIG. 2 can be carried out much more quickly than using those illustrated in FIG. 1.

Comme le montre la figure 2, le palier d'articulation de l'anneau 5 dans l'extrémité de la boucle 2a solidaire de la patte de fixation 2b,est constitué par deux pattes 7 découpées dans ladite extrémité de la boucle 2a et cintrées sensiblement au profil de la section transversale de l'anneau 5. Cette disposition présente l'avantage de rendre totalement imperdables les moyens de fermeture de la boucle 2a.  As shown in Figure 2, the hinge bearing of the ring 5 in the end of the loop 2a integral with the fixing lug 2b, is constituted by two lugs 7 cut in said end of the loop 2a and substantially bent to the profile of the cross section of the ring 5. This arrangement has the advantage of making the closure means of the loop 2a totally captive.

Comme il va de soi et comme il ressort de ce qui précède, l'invention ne se limite pas aux seules formes d'exécutions de ces moyens de suspension qui ont été décrites ci-dessus à titre d'exemples non limitatifs; elle en embrasse, au contraire, toutes les variantes de réalisation.  As is obvious and as is clear from the above, the invention is not limited to the sole forms of execution of these suspension means which have been described above by way of nonlimiting examples; on the contrary, it embraces all of its variant embodiments.
