Description

Pour manutentionner des charges lourdes et fragiles, il est connu d'utiliser des sangles plates formées d'une série de câbles parallèles qui assurent une répartition de la charge sur toute la largeur de la sangle voir p.e. FR-A-1151492. Il est également connu d'assurer une protection des câbles de l'élingue, soit en noyant l'ensemble des câbles dans un enrobage en matière élastomère, soit en enfilant les câbles dans des éléments jointifs en élastomère disposés en quinconce. Mais cet enrobage ou ces éléments de protection ôtent 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 tôle dans laquelle la sangle est enfilée, et risque d'entraîner une détérioration de la sangle. En outre, on ne peut facilement réparer la sangle si la protection est endommagée.To handle heavy and fragile loads, it is known to use flat straps formed by a series of parallel cables which ensure a distribution of the load over the entire width of the strap see e.g. FR-A-1151492. 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 elastomeric contiguous 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 sheet metal coil into which the strap is threaded, and risks causing deterioration of the strap. In addition, the strap cannot be easily repaired if the protection is damaged.

La présente invention a pour objet une sangle à câbles parallèles dans laquelle les câbles sont associés à 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 est caractérisée en ce que les éléments de protection d'une même rangée sont articulés l'un par rapport à l'autre avec jeu, les éléments des diverses rangées étant reliés entre eux par un ou plusieurs câbles de liaison. Du fait de la liaison articulée des maillons d'une même rangée, la sangle peut être pliée autour d'un axe longitudinal.The strap according to the invention is characterized in that 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 . Due to the articulated connection of the links of the same row, the strap can be folded around a longitudinal axis.

Les éléments adjacents d'une même rangée peuvent être reliés entre eux par une articulation constituée par exemple par un rivet. En variante, les articulations des diverses rangées peuvent être constituées par un même câble s'étendant sur toute la longueur de la sangle et traversant avec jeu des trous des éléments.The adjacent elements of the same row can be interconnected by a hinge formed for example by a rivet. As a variant, the articulations of the various rows may consist of the same cable extending over the entire length of the strap and crossing with clearance the holes of the elements.

Dans un premier mode de réalisation chaque élément de protection présente une lumière allongée débouchant à l'extérieur par une ouverture de largeur supérieure au diamètre d'un câble mais toutefois inférieure à la somme des diamètres des câbles qui y sont introduits, de telle sorte que lesdits câbles soient retenus dans cette lumière et les éléments ayant leur ouverture tournée vers l'une des faces de la sangle sont disposés en quinconce avec les éléments ayant leur ouverture tournée vers la face opposée.In a first embodiment, each protective element has an elongated light opening to the outside through an opening of width greater than the diameter of a cable but nevertheless less than the sum of the diameters of the cables which are introduced therein, so that said cables are retained in this light and the elements having their opening facing one of the sides of the strap are staggered with the elements having their opening facing the opposite face.

Dans un autre mode de réalisation, chaque élément de protection comporte un trou indépendant pour le passage de chaque câble. Des bagues peuvent être montées sur les câbles de liaison entre les éléments de protection et serties à ces câbles. Ces bagues empêchent les éléments de protection aussi bien de se rapprocher que de s'éloigner les uns des autres au-delà d'une valeur donnée.In another embodiment, each protection element has an independent hole for the passage of each cable. Rings can be mounted on the connection cables between the protection elements and crimped to these cables. 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, à titre d'exemples non limitatifs deux modes 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, dans un premier mode de réalisation;
  • La Figure 2 en est une coupe suivant II-II de la Figure 1;
  • La Figure 3 est une vue en plan montrant deux éléments de protection articulés l'un à l'autre;
  • La Figure 4 en est une vue en élévation;
  • La Figure 5 est une vue semblable à la Figure 4 d'une variante;
  • La Figure 6 est une vue en plan d'une partie de la sangle, dans un second mode de réalisation;
  • La Figure 7 en est une coupe suivant VII-VII de la Figure 6;
  • La Figure 8 est une vue en bout d'un élément de protection de la sangle des Figures 6 et 7.
Two embodiments of the strap according to the invention have been described below, by way of non-limiting examples, with reference to the appended drawing in which:
  • Figure 1 is a plan view of part of the strap, in a first embodiment;
  • Figure 2 is a section along II-II of Figure 1;
  • Figure 3 is a plan view showing two protective elements hinged to each other;
  • Figure 4 is an elevational view thereof;
  • Figure 5 is a view similar to Figure 4 of a variant;
  • Figure 6 is a plan view of part of the strap, in a second embodiment;
  • Figure 7 is a section along VII-VII of Figure 6;
  • Figure 8 is an end view of a protective element of the strap of Figures 6 and 7.

Telle qu'elle est représentée aux Figures 1 à 4, la sangle selon l'invention comprend une série de câbles parallèles 1 qui sont au nombre de quatre dans le mode de réalisation des Figures 1 et 2.As shown in Figures 1 to 4, the strap according to the invention comprises a series of parallel cables 1 which are four in number in the embodiment of Figures 1 and 2.

Les câbles 1 sont associés à une série d'éléments de protection qui sont désignés d'une façon générale par la référence 2 et 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 which are generally designated by the reference 2 and 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 une lumière allongée 4 qui peut recevoir avec un certain jeu deux ou plusieurs câbles 1 disposés côte à côte et débouche à l'extérieur par une ouverture 5 de largeur supérieure au diamètre d'un câble 1 mais inférieure au double de ce diamètre.Each element 2 has an elongated lumen 4 which can receive with a certain play two or more cables 1 arranged side by side and opens to the outside by an opening 5 of width greater than the diameter of a cable 1 but less than twice that diameter.

Les deux éléments d'une même paire ont l'un 2a son ouverture 5 tournée vers l'une des faces de la sangle et l'autre 2b son ouverture tournée vers l'autre face. Les paires d'éléments sont montées côte à côte, têtebêche.The two elements of the same pair have one 2a its opening 5 facing one side of the strap and the other 2b its opening facing the other side. The pairs of elements are mounted side by side, head to tail.

Les éléments 2a ayant leur ouverture 5 tournée vers une face de la sangle sont ainsi disposés en quinconce avec les éléments 2b ayant leur ouverture 5 tournée vers la face opposée.The elements 2a having their opening 5 facing one side of the strap are thus staggered with the elements 2b having their opening 5 facing the opposite side.

Du fait de ce montage, un élément 2a (ou 2b) se trouve longitudinalement entre deux éléments 2b (ou 2a) en étant séparés de ceux-ci d'une distance sensiblement égale à l'épaisseur d'un élément de protection. Entre deux éléments 2a et 2b voisins est disposé un élément d'écartement de faible largeur 8 qui peut être constitué par un tronçon d'élément 2, comme on le voit à la Figure 2, ou par un simple bout de tube.Due to this arrangement, an element 2a (or 2b) is located longitudinally between two elements 2b (or 2a) being separated from them by a distance substantially equal to the thickness of a protective element. Between two neighboring elements 2a and 2b is arranged a spacer element of small width 8 which can be constituted by a section of element 2, as can be seen in FIG. 2, or by a simple end of tube.

Les divers éléments 2a, 2b et 8 sont reliés entre eux par des câbles 7 passant dans un trou 6 des éléments.The various elements 2a, 2b and 8 are interconnected by cables 7 passing through a hole 6 of the elements.

On notera que ces câbles 6 sont uniquement des câbles de liaison et ne sont pratiquement soumis à aucune charge lors de l'utilisation de la sangle.It will be noted that these cables 6 are only connecting cables and are practically not subjected to any load when using the strap.

Dans la variante de la Figure 5, chaque rangée d'éléments comprend trois éléments reliés entre eux avec jeu par des rivets 3, les éléments ayant leurs ouvertures 5 tournées alternativement vers l'une des faces de la sangle et vers la face opposée.In the variant of FIG. 5, each row of elements comprises three elements connected to each other with play by rivets 3, the elements having their openings 5 turned alternately towards one of the faces of the strap and towards the opposite face.

Dans le mode de réalisation des Figures 6 à 8, chaque élément 2 présente des trous 4a séparés par un pont 4b et dans chacun desquels l'un des câbles 1 passe avec un léger jeu. Les éléments 2 sont reliés entre eux par des câbles 6 sur lesquels sont disposées et serties des bagues 9 séparant les éléments 2 adjacents les uns des autres. Les bords longitudinaux des éléments 2 sont arrondis, comme on le voit à la Figure 8.In the embodiment of Figures 6 to 8, each element 2 has holes 4a separated by a bridge 4b and in each of which one of the cables 1 passes with a slight clearance. The elements 2 are interconnected by cables 6 on which are arranged and crimped rings 9 separating the elements 2 adjacent to each other. The longitudinal edges of the elements 2 are rounded, as seen in Figure 8.
