Abstract

Dispositif pour réaliser une goupille d’axe. L’invention concerne un dispositif qui permet de réaliser une goupille 3 d’axe 23 pour éviter les risques de perte ou de dégradation. Il est constitué d’une bague 4 présentant deux alésages 5 la traversant axialement aptes à recevoir une goupille cylindrique 3 qui sera introduite dans l’orifice de l’axe 23 prévu à cet effet. Sur une partie distale de cette goupille 3 deux rainures parallèles 32 viennent en contact et emprisonnent les deux branches coudées 20 des ressorts 2 en fil disposés dans des rainures 12 usinées dans une des faces de la bague 4. Une rainure 30 ou une autre forme au sommet de la goupille 3 permet à l’aide d’un outil 37 sa rotation. Par appui des deux branches coudées 20 des ressorts 2 dans les rainures 32 la goupille 3 est bloquée. Lorsque l’utilisateur fait tourner d’un quart de tour la goupille 3 à l’aide d’un outil 37 approprié les deux branches coudées 20 des ressorts 2 s’écartent et la goupille 3 est libérée. Un capuchon 43 de protection en caoutchouc ou en une résine souple vient protéger l’ensemble du dispositif empêchant une sortie inopinée de la goupille 3 tout en protégeant le dispositif des éléments extérieurs. Le dispositif suivant l’invention est particulièrement destiné à la réalisation de goupille 3 de sécurité pour axe 23.Device for making an axle pin. The invention relates to a device which makes it possible to produce a pin 3 with an axis 23 to avoid the risk of loss or damage. It consists of a ring 4 having two bores 5 passing through it axially capable of receiving a cylindrical pin 3 which will be introduced into the orifice of the axis 23 provided for this purpose. On a distal part of this pin 3, two parallel grooves 32 come into contact and trap the two bent branches 20 of the wire springs 2 arranged in grooves 12 machined in one of the faces of the ring 4. A groove 30 or another shape at the same time. top of the pin 3 allows it to rotate using a tool 37. By pressing the two bent branches 20 of the springs 2 in the grooves 32 the pin 3 is blocked. When the user turns the pin 3 a quarter of a turn using a suitable tool 37 the two bent branches 20 of the springs 2 move apart and the pin 3 is released. A protective cap 43 made of rubber or a flexible resin protects the entire device preventing an unexpected release of the pin 3 while protecting the device from external elements. The device according to the invention is particularly intended for producing a safety pin 3 for axis 23.
