Abstract

The tool has a tubular socket machined at one of its ends to correspond to the nut or bolt (1). It has at the other end, in periphery, a longitudinal cog on the interior wall, on the exterior wall or on the two (2). The tool also has a handle equipped with two grooves (3). Each of these grooves being at opposite ends of the edge of one or several catches (4) corresponding to the cog of the sprocket and in driving rotation, in one sense or the other. USE - Allows the screwing and screwing of nuts or bolts.

Description

La présente invention concerne un dispositif permettant de serrer ou de desserrer un écrou ou boulon grâce à une douille et à un manche (ou poignée) auto-bloquant, à retour libre, sans aucun mécanisme additionnel.The present invention relates to a device for tightening or loosening a nut or bolt by means of a socket and a self-locking handle (or handle), with free return, without any additional mechanism.

Traditionnellement, le serrage des boulons ou écrous se fait à l'aide d'une clef classique, imposant un grand nombre de manoeuvres ou d'une clef à cliquet équipée d'une douille, ayant l'inconvénient de présenter une grande inertie au retour et d'être limitée par la profondeur de la douille par rapport à la longueur de la tige filetée dépassante.Traditionally, the tightening of bolts or nuts is done using a conventional key, requiring a large number of operations or a ratchet key equipped with a socket, having the disadvantage of having a great inertia on return and to be limited by the depth of the sleeve relative to the length of the protruding threaded rod.

Le dispositif, selon l'invention, permet de remédier à ces inconvénients.The device according to the invention overcomes these drawbacks.

I1 comporte en effet, selon une première caractéristique, une douille entièrement tubulaire (FIG. 1.2.3.) pouvant donc être entièrement traversée par la tige filetée, usinée à une de ses extrémités pour correspondre à 1 l'écrou ou au boulon (1) et comportant à 1 l'autre extrémité, en périphérie, un crantage longitudinal sur la paroi intérieure, sur la paroi extérieure ou sur les deux (2), et un manche (FIG. 4.5) équipé de deux rainures (3) s'emboitant sur un secteur de la rive crantée de la douille, chacune de ses rainures étant pourvue aux extrémités opposées de chacune de ses rives d'un ou plusieurs ergots (4) correspondant au crantage de la douille et l'entrainant dans sa rotation, dans un sens ou dans l'autre. I1 indeed has, according to a first characteristic, a fully tubular socket (FIG. 1.2.3.) Which can therefore be entirely traversed by the threaded rod, machined at one of its ends to correspond to 1 the nut or the bolt (1 ) and comprising at 1 the other end, at the periphery, a longitudinal notch on the inner wall, on the outer wall or on both (2), and a handle (FIG. 4.5) equipped with two grooves (3) s' fitting onto a sector of the notched edge of the sleeve, each of its grooves being provided at the opposite ends of each of its edges with one or more lugs (4) corresponding to the notching of the sleeve and causing it to rotate, in one way or the other.

La position des ergots détermine le sens de rotation de la douille pour le serrage et le desserrage.The position of the pins determines the direction of rotation of the sleeve for tightening and loosening.

Les extrémités de chacune des rives des rainures sont lisses afin de permettre le retour libre.The ends of each of the edges of the grooves are smooth to allow free return.

Fonctionnement: la douille étant engagée dans la rainure, un mouvement sectoriel du manche engage les ergots dans les crans de la douille, entrainant celle-ci dans sa rotation. Lors du retour, les ergots se dégagent automatiquement du crantage et la rainure glisse librement sur les bords de la douille. La répétition du mouvement renouvelle la procédure.Operation: the sleeve being engaged in the groove, a sectoral movement of the handle engages the pins in the notches of the sleeve, causing the latter to rotate. When returning, the pins are automatically released from the notching and the groove slides freely on the edges of the sleeve. The repetition of the movement renews the procedure.

Selon des modes différents de fabrication, - la douille ou le manche est magnétisé pour parfaire le maintien de l'ensemble; - les rainures d'entrainement sont à chaque extrémité du manche; - les rainures d'entrainement sont dos à dos à la même extrémité du manche. According to different manufacturing methods, - the socket or the handle is magnetized to complete the maintenance of the assembly; - the drive grooves are at each end of the handle; - the drive grooves are back to back at the same end of the handle.
