Patent

CA 2249794

The socket wrench extension has an insertion member with a polygonal socket head having a lateral socket head surface. A receiving member with a polygonal socket is provided and a tube rigidly connects the insertion member and the receiving member. The locking member is moveably connected within the insertion member such that the locking element partially projects from the lateral socket head surface. The pressure transmission member is axially moveable in the tube. The pressure transmission member has a first and a second end. The first end serves as an actuation member for the pressure transmission member. The second end transforms the axial movement of the pressure transmission member, directed toward the insertion member, into an outward movement of the locking member. The receiving member has an axial bore and a guide sleeve which is inserted into the axial bore of the receiving member for guiding the first end of the pressure transmission member. The guide sleeve has an insertion diameter (press-fit diameter) that is greater than the maximum diameter of the pressure transmission member.

Rallonge d'une clé à douille comprenant un élément d'insertion à tête creuse polygonale ayant une surface de tête latérale. Un élément receveur à douille polygonale est raccordé solidement à l'élément d'insertion par un tube. L'élément de verrouillage est relié de façon mobile à l'intérieur de l'élément d'insertion de façon que l'élément de verrouillage se projette en partie depuis la surface de tête latérale. L'élément transmetteur de pression se déplace de manière axiale dans le tube. Cet élément comprend une première et une deuxième extrémités. La première extrémité sert à actionner l'élément transmetteur de pression. La deuxième extrémité transforme le déplacement axial de l'élément transmetteur de pression, dirigé vers l'élément d'insertion, en un déplacement extérieur de l'élément de verrouillage. L'élément receveur comprend un alésage axial et un manchon de guidage y est inséré afin de guider la première extrémité de l'élément transmetteur de pression. Le manchon de guidage comprend un diamètre d'insertion (diamètre ajusté à la presse) qui est plus grand que le diamètre maximal de l'élément transmetteur de pression.
