Abstract
Les organes de verrouillage (4) pour un tampon (2) articulé sur un cadre (1) comprennent :- une béquille (5) montée pivotante sur le cadre et présentant une rainure longiligne (9) ;- une tige d’entraînement (11) solidaire du tampon et engagée à coulissement dans la rainure longiligne ;- un doigt de sécurité (12) monté pivotant sur la béquille entre une position non basculée dans laquelle il n’obture pas la rainure longiligne et une position basculée de blocage dans laquelle il l’obture ;- un dispositif de rappel élastique (13) qui déplace le doigt de sécurité dans sa position basculée. Lors de l’ouverture du tampon, la tige d’entraînement coulisse dans la rainure longiligne et pousse le doigt de sécurité dans sa position non basculée, ledit doigt de sécurité revenant dans sa position basculée par le dispositif de rappel élastique après le passage de la tige d’entraînement pour empêcher la fermeture du tampon. Figure pour l’abrégé : Fig 3The locking members (4) for a buffer (2) articulated on a frame (1) comprise: - a crutch (5) pivotally mounted on the frame and having an elongated groove (9); - a drive rod (11) ) integral with the buffer and slidably engaged in the elongated groove; - a safety finger (12) pivotably mounted on the stand between an unswitched position in which it does not block the elongated groove and a tilted locking position in which it the closure; - an elastic return device (13) which moves the safety finger into its tilted position. When opening the buffer, the drive rod slides in the elongated groove and pushes the safety finger into its non-tilted position, said safety finger returning to its tilted position by the elastic return device after the passage of the drive rod to prevent closure of the pad.
