Abstract

The spanner (1) includes a handle (2) at the end of which a hexagon (3) is forged, and a ring (5) inserted in a slot or a groove (4) that is formed inside the hexagon. The ring is made of a flexible rubber material and projects beyond the body of the spanner, in order to fill the clearance of the spanner and to block the spanner on a nut.

Description

La présente invention concerne un outil à main permettant de serrer ouThe present invention relates to a hand tool for tightening or

desserrer des écrous récalcitrants en raison de leur taille ou d'un grippage.  loosen recalcitrant nuts because of their size or galling.

Dans l'industrie, les écrous sont souvent larges et la corrosion importante. Les écrous grippés sont traditionnellement serrés ou desserrés à l'aide d'une clé à frapper, placée sur l'écrou, sur laquelle l'opérateur tape avec une masse pour gagner de la puissance. Toutefois, la clé ayant du jeu, elle a tendance à rebondir et à sortir de l'écrou. Pour éviter ce rebond, l'opérateur maintient la clé avec ses mains ou ses pieds au risque de se blesser.  In industry, nuts are often wide and corrosion is important. The seized nuts are traditionally tightened or loosened using a knock-on wrench, placed on the nut, on which the operator taps with a mass to gain power. However, the key having play, it tends to bounce and out of the nut. To avoid this rebound, the operator holds the key with his hands or feet at the risk of injury.

Le dispositif selon l'invention permet de remédier à cet inconvénient. Il se présente selon une première caractéristique en une clé à frapper, un manche muni d'un hexagone, l'invention concerne l'insertion d'une matière flexible fixée à l'intérieur de l'hexagone permettant de maintenir la clé sur l'écrou lors de la frappe grâce à ce système anti-retour.  The device according to the invention overcomes this disadvantage. It is presented according to a first characteristic in a hitting key, a handle provided with a hexagon, the invention relates to the insertion of a flexible material fixed inside the hexagon to hold the key on the nut when typing thanks to this anti-return system.

Ce dispositif selon une première version se présente sous la forme d'un jonc introduit dans une fente ou rigole située à l'intérieur de l'hexagone, ses dimensions sont déterminées par la taille de la clé, ellemême déterminée par la taille de l'écrou à serrer ou desserrer. Néanmoins, le jonc doit être suffisamment long pour combler le jeu de la clé et la bloquer sur l'écrou.  This device according to a first version is in the form of a rod introduced into a slot or channel located inside the hexagon, its dimensions are determined by the size of the key, itself determined by the size of the nut to tighten or loosen. Nevertheless, the ring must be long enough to fill the play of the key and lock it on the nut.

Selon un mode particulier de réalisation: - le jonc inséré sur la totalité de l'hexagone est remplacé par une lamelle en matière flexible dont la largeur est limitée.  According to a particular embodiment: - the ring inserted on the entire hexagon is replaced by a flexible material lamella whose width is limited.

- cette lamelle peut être placée plus particulièrement dans le manche de la clé dans lequel la fente d'insertion sera plus profonde.  this lamella may be placed more particularly in the handle of the key in which the insertion slot will be deeper.

Les dessins annexés illustrent l'invention: La figure 1 représente le dispositif de l'invention.  The accompanying drawings illustrate the invention: FIG. 1 represents the device of the invention.

La figure 2 représente une variante de ce dispositif.  Figure 2 shows a variant of this device.

En référence au dessin figure 1, l'outil est une clé à frapper (1) qui se décompose en un manche (2) et un hexagone (3). A l'intérieur de cet hexagone (3), une rigole (4) est usinée afin de permettre l'insertion d'un jonc (5) qui bloque la clé sur l'écrou. L'opérateur insert l'hexagone (3) de la clé à frapper (1) autour d'un écrou, puis il tape sur le manche (2) à l'aide d'une masse afin de provoquer la rotation de la clé (1) et serrer ou desserrer l'écrou. Le jonc (5) se coince entre l'hexagone et l'écrou et empêche la clé (1) de rebondir.  Referring to the drawing Figure 1, the tool is a key to hit (1) which breaks down into a handle (2) and a hexagon (3). Inside this hex (3), a channel (4) is machined to allow the insertion of a ring (5) which locks the key on the nut. The operator inserts the hexagon (3) of the knock-on wrench (1) around a nut, then he taps on the handle (2) with a mass to cause the rotation of the key ( 1) and tighten or loosen the nut. The ring (5) gets stuck between the hexagon and the nut and prevents the key (1) from bouncing.

Dans la forme de réalisation selon la figure 2, une fente (4) est usinée dans l'hexagone (3), afin de permettre l'insertion d'une lamelle (5) qui bloque la clé sur l'écrou.  In the embodiment according to Figure 2, a slot (4) is machined in the hexagon (3), to allow the insertion of a blade (5) which locks the key on the nut.

A titre d'exemple non limitatif, la lamelle en matière flexible aura des dimensions de l'ordre de 10 à 33 mm pour la largeur, de 8 à 11 mm pour la profondeur et une épaisseur variant de 2 à 5 mm et le jonc aura un diamètre de 24 à 130 mm et une épaisseur variant de 1 à 3 mm.  By way of non-limiting example, the lamella of flexible material will have dimensions of the order of 10 to 33 mm for the width, 8 to 11 mm for the depth and a thickness ranging from 2 to 5 mm and the rod will have a diameter of 24 to 130 mm and a thickness ranging from 1 to 3 mm.

Le dispositif de l'invention est particulièrement destiné à l'industrie pour le serrage et desserrage d'écrous.  The device of the invention is particularly intended for the industry for tightening and loosening nuts.
