Abstract
Description
Pour manutentionner des charges lourdes et fragiles, il est connu d'utiliser des sangles plates formées d'une série de cables parallèles qui assurent une répartition de la charge sur toute la largeur de la sangle.To handle heavy and fragile loads, it is known to use flat straps formed from a series of parallel cables which distribute the load over the entire width of the strap.
Il est également connu d'assurer une protection des cables de l'élingue, soit en noyant l'ensemble des cables dans un enrobage en matière élastomere, soit en enfilant les cables dans des éléments jointifsenélas- tombé disposes en quinconce. Mais cet enrobage ou ces éléments de protection otent pratiquement à la sangle toute flexibilité autour d'un axe longitudinal. Cette absence de flexibilité présente des inconvénients, par exemple lors du transport d'une bobine de tble dans laquelle la sangle est enfilée, et risque d'entraîner une détérioration de la sangle. It is also known to provide protection for the cables of the sling, either by drowning all the cables in a coating of elastomeric material, or by threading the cables in joined-in-fallen elements arranged in staggered rows. But this coating or these protective elements virtually remove the flexibility of the strap around a longitudinal axis. This lack of flexibility has drawbacks, for example when transporting a reel of cable in which the strap is threaded, and risks causing deterioration of the strap.
La présente invention a pour objet une sangle a câbles parallèles dans laquelle les câbles sont associés a des éléments de protection disposés en rangées et qui évite ces inconvénients.The present invention relates to a strap with parallel cables in which the cables are associated with protective elements arranged in rows and which avoids these drawbacks.
La sangle selon l'invention, dans laquelle les éléments de protection d'une méme rangée sont articulés l'un par rapport a l'autre avec jeu, les éléments des diverses rangées étant reliés entre eux par un ou plusieurs Ca- bles de liaison, est caractérisée en ce que chaque élément de protection comporte un trou indépendant pour le passage de chaque câble.The strap according to the invention, in which the protective elements of the same row are articulated with respect to each other with play, the elements of the various rows being interconnected by one or more connecting cables , is characterized in that each protective element has an independent hole for the passage of each cable.
Dans un mode de réalisation particulier de l'invention, des bagues sont montées sur les cibles de liaison entre les éléments de protection et serties a ces cabales. In a particular embodiment of the invention, rings are mounted on the connecting targets between the protective elements and crimped to these cabals.
Ces bagues empêchent les éléments de protection aussi bien de se rapprocher que de s'éloigner les uns des autres au-dela d'une valeur donnée.These rings prevent the protective elements from approaching as well as moving away from each other beyond a given value.
On a décrit ci-après, a titre d'exemple non limitatif, un mode de réalisation de la sangle selon l'invention, avec référence au dessin annexé dans lequel
La Figure 1 est une vue en plan d'une partie de
la sangle;
La Figure 2 en est une coupe suivant II-II de la
Figure 1
La Figure 3 est une vue en bout d'un élément de
protection.An embodiment of the strap according to the invention has been described below, by way of non-limiting example, with reference to the appended drawing in which
Figure 1 is a plan view of part of
the strap;
Figure 2 is a section along II-II of the
Figure 1
Figure 3 is an end view of an element of
protection.
Telle qu'elle est représentée au dessin, la sangle selon l'invention comprend une série de câbles paral lèles 1 qui sont au nombre de quatre dans le mode de réalisation représenté.As shown in the drawing, the strap according to the invention comprises a series of parallel cables 1 which are four in number in the embodiment shown.
Les cables 1 sont associés a une série d'éléments de protection 2 qui ont une forme approximativement rectangulaire. Ces éléments de protection sont disposés en rangées de deux et les éléments d'une même rangée sont reliés l'un à l'autre avec un certain jeu, par un rivet 3.The cables 1 are associated with a series of protective elements 2 which have an approximately rectangular shape. These protective elements are arranged in rows of two and the elements of the same row are connected to each other with a certain clearance, by a rivet 3.
Chaque élément 2 présente des trous 4a séparés par un pont 4b et dans chacun desquels l'un des cibles 1 passe avec un léger jeu. Les éléments 2 sont reliés entre eux par des cibles 6 sur lesquels sont disposées et serties des bagues 7 séparant les éléments 2 adjacents les uns des autres.Each element 2 has holes 4a separated by a bridge 4b and in each of which one of the targets 1 passes with a slight clearance. The elements 2 are connected together by targets 6 on which are arranged and crimped rings 7 separating the elements 2 adjacent to each other.
I1 va de soi que la présente invention ne doit pas être considérée comme limitée au mode de réalisation decrit et représenté, mais en couvre, au contraire, toutes les variantes. I1 goes without saying that the present invention should not be considered as limited to the embodiment described and shown, but covers, on the contrary, all variants.
