Abstract

The tensioning device comprises a threaded orifice (1) in a support block into which the crimped cable (2) may be inserted. The cable has a crimped ferrule (5) on its end, applied after the cable has already passed through a bolt (3) having an axial hole (4). When the bolt is threaded into the hole, the cable is tensioned as the bolt acts on the ferrule at the cable end. The ferrule may alternatively be retained by a small screw acting at right angles to the cable axis. USE - For retaining cables, shafts and wires within metal or other mechanically strong material.

Description

DESCRIPTION
La présente invention concerne un dispositif pour tendre les câbles.DESCRIPTION
The present invention relates to a device for tensioning cables.

Les tendeurs de fils métalliques sont traditionnellement crochetés à un point d'ancrage indépendant et impriment leur tension aux câbles par le vissage de la partie centrale du dispositif ce qui tend à rapprocher le crochet côté câbles vers l'autre partie identique crochetée ou point d'ancrage. The metal wire tensioners are traditionally hooked at an independent anchoring point and imprint their tension on the cables by screwing the central part of the device which tends to bring the hook on the cable side towards the other identical hooked part or point of anchoring.

Le dispositif selon l'invention permet de remédier à cet inconvénient. The device according to the invention overcomes this drawback.

I1 comporte en effet selon une première caractéristique. un orifice taraudé dans un support. Dans cet orifice est introduit un embout serti sur le câbles et une vis présentant un orifice sur son axe dans lequel sont introduits les câbles. I1 indeed has according to a first characteristic. a threaded hole in a support. In this orifice is introduced a ferrule crimped on the cables and a screw having an orifice on its axis in which the cables are introduced.

L'orifice taraudé par lequel est engagé la vis, emprisonne l'embout serti sur les câbles. Ces derniers empruntent l'orifice présent dans la vis accédant ainsi vers l'extérieur du dispositif. The threaded hole through which the screw is engaged, traps the crimped end on the cables. These borrow the orifice present in the screw thus accessing towards the outside of the device.

Lors du serrage de la vis par l'utilisateur, la vis exerce une pression sur l'embout et simultanément imprime une tension identique à tous les câbles. When the screw is tightened by the user, the screw exerts pressure on the end cap and simultaneously prints the same tension on all cables.

Selon des modes particuliers de réalisation
-l'embout serti peut être substitué par une bague de serrage.According to particular embodiments
-the crimped end can be replaced by a clamping ring.

-une rondelle ou un roulement peut être inséré entre l'embout serti et la vis percée. -a washer or a bearing can be inserted between the crimped end and the drilled screw.

-la vis peut etre substituée par une tige filetée. -the screw can be replaced by a threaded rod.

-la tige filetée peut être protégée par un capuchon. -the threaded rod can be protected by a cap.

-les câbles peuvent être substitués par des fils ou tiges. -cables can be replaced by wires or rods.

-les câbles peuvent être combinés avec des fils et tiges. -cables can be combined with wires and rods.

Les dessins annexés illustrent l'invention : La figure 1 représente en coupe le dispositif selon l'invention. La figure 2 représente en coupe une variante de ce dispositif. The accompanying drawings illustrate the invention: Figure 1 shows in section the device according to the invention. Figure 2 shows in section a variant of this device.

En référence à ces dessins. le dispositif comporte un orifice taraudé (1) dans un support dans lequel (1) est introduit librement un embout serti (5) sur les câbles (2) et une vis (3) présentant un orifice (4) percé sur son axe dans lequel (4) sont introduits librement les câbles (2). Lors du vissage, par l'utilisateur, de la vis (3) dans l'orifice taraudé (1). la vis (3) exerce une pression sur l'embout (5) emprisonné dans l'orifice (1) et imprime directement une tension identique sur les câbles (2). With reference to these drawings. the device comprises a threaded orifice (1) in a support in which (1) is freely introduced a crimped end (5) on the cables (2) and a screw (3) having an orifice (4) drilled on its axis in which (4) cables (2) are freely inserted. When the user screws the screw (3) into the threaded hole (1). the screw (3) exerts pressure on the endpiece (5) trapped in the orifice (1) and directly prints an identical tension on the cables (2).

Selon une variante non illustrée, l'embout est serti indifféremment sur des câbles, fils ou tiges.  According to a variant not illustrated, the end piece is crimped either on cables, wires or rods.

A titre d'exemple non limitatif, l'orifice taraudé (1) aura une profondeur de 20 mm et un diamètre de 8 mm, le corps de la vis (3) aura une longueur de 25 mm et un diamètre de 8 min et l'orifice (4) percé aura un diamètre de 3,2 mm pouvant ainsi recevoir jusqu'à 7 câbles (2) de 1 mm de diamètre. Toujours à titre d'exemple non limitatif, l'embout serti (5) aura pour dimensions 7 mm de diamètre et 6 mm de hauteur, l'engagement de la vis (3) dans l'orifice taraudé (1) sera de 13 mm. identique sera la marge de tension de câbles (2). By way of nonlimiting example, the threaded orifice (1) will have a depth of 20 mm and a diameter of 8 mm, the body of the screw (3) will have a length of 25 mm and a diameter of 8 min and l the orifice (4) drilled will have a diameter of 3.2 mm, which can thus receive up to 7 cables (2) of 1 mm in diameter. Still by way of nonlimiting example, the crimped end piece (5) will have the dimensions of 7 mm in diameter and 6 mm in height, the engagement of the screw (3) in the tapped hole (1) will be 13 mm. . identical will be the cable tension margin (2).

La forme de réalisation selon la figure 2 comporte un orifice taraudé (1) dans lequel est introduit une bague de serrage (6) des câbles (2). The embodiment according to Figure 2 comprises a threaded orifice (1) into which is introduced a clamping ring (6) of the cables (2).

Une tige filetée (9), munie d'un orifice (4) percé sur son axe, est vissée dans l'orifice taraudé (1). La tige filetée (9) présente par son orifice (4) un libre accés aux câbles (2) vers l'extérieur du dispositif. A threaded rod (9), provided with an orifice (4) drilled on its axis, is screwed into the threaded orifice (1). The threaded rod (9) has through its orifice (4) free access to the cables (2) to the outside of the device.

Sur la partie visible de la tige filetée (9) est vissé un capuchon (10) permettant d'opérer manuellement sur la tension des câbles (2). Le capuchon (10) est muni d'un orifice de 3,2 mm laissant ainsi passer les câbles (5). On the visible part of the threaded rod (9) is screwed a cap (10) allowing manual operation on the tension of the cables (2). The cap (10) is provided with a hole of 3.2 mm thus allowing the cables (5) to pass.

Entre la bague de serrage (6) et la tige (9) est insérée une rondelle (7) ou un roulement (8) diminuant ainsi le frottement entre la bague (6) et la tige (9) lors de fortes tensions et évitant le risque de torsion des câbles (2) à l'intérieur du dispositif. Between the clamping ring (6) and the rod (9) is inserted a washer (7) or a bearing (8) thus reducing the friction between the ring (6) and the rod (9) during high tensions and avoiding the risk of twisting the cables (2) inside the device.

Selon une variante non illustrée, l'embout serti, ou la bague de serrage, peut être muni de fils, tiges et analogues. Une combinaison de ces trois derniers peut être réalisée. According to a variant not illustrated, the crimped end piece, or the clamping ring, may be provided with wires, rods and the like. A combination of these last three can be achieved.

Le dispositif est réalisé en métal d'une résistance mécanique supérieure aux efforts impliqués par la tension ; les matériaux composites ne sont pas exclus. The device is made of metal with a mechanical resistance greater than the forces involved in tension; composite materials are not excluded.

A titre d'exemple non limitatif, les dimensions sont identiques dans les 2 formes de réalisation. By way of nonlimiting example, the dimensions are identical in the 2 embodiments.

Le dispositif selon l'invention est particulièrement destiné à la tension des câbles, fils. tiges, ou analogues.  The device according to the invention is particularly intended for tensioning cables, wires. rods, or the like.
