Title: Outil de vissage a tige remplacable
Inventor: ABEL MICHAEL
IPC: B25B23/00
Filed: 2003-07-21
Abstract: L'invention concerne un outil de vissage (1) comprenant un manche (2) et une tige (3), reçue de façon amovible dans un évidement ouvert (4) sur la face avant du manche (2), laquelle tige présente une section d'actionnement (5) sur son extrémité libre. Selon ladite invention, cette tige (3) est solidarisée au manche dans une position d'utilisation par l'intermédiaire d'un élément de fixation (14), associé à ce manche (2), et bloquée dans le sens axial. Cet élément de fixation (14) peut être également déplacé dans une position de retrait par le déplacement d'un organe d'actionnement (6), de sorte que la tige peut être retirée du manche (2). Cette invention est principalement caractérisée en ce qu'une grande partie de la tige (3) se trouve dans ledit évidement (4), lorsque cette tige est en position de fixation, et cette dernière est maintenue dans cet évidement par l'intermédiaire de moyens de maintien (H). Ces moyens de maintien peuvent être desserrés, de sorte que la partie de la tige (3), située dans l'évidement (4), peut sortir de cet évidement (4) contre une butée (A) sous l'effet d'une force jusqu'à une section de maintien (H) de cette tige, associée à l'extrémité fixe de cette dernière, de manière à passer en position d'utilisation. L'organe d'actionnement associé au manche (2) peut être déplacé dans une position de desserrage permettant de desserrer le moyen de maintien (H).

Abstract: A supply connection device for a fluid pressure system, the connection includes a head designed to be axially received in a body of a supply intake, and the connection is capable of being locked in a front position axially engaged in the supply intake body by a locking mechanism, which includes a globally symmetrical U-shaped pin with two transverse locking branches. The connection is unlocked from the body, for axially releasing, at least partly, rearward the connection outside the body, by elastic deformation of the locking mechanism which results from the co-operation between at least a part of the locking branches and at least a part of the body under the action of a releasing force exerted on the locking mechanism along a transverse direction. The elastic deformation is obtained by exerting a releasing force thrusting a connecting section of the two braches of the pin.
