Abstract (en)
[origin: EP0230263A2] 1. Automatic coupler for rail vehicles, - with a coupler head according to the Willison principle, one coupler mouth (3) being laterally bordered by coupler claws (1, 2) ; - with a locking gear, arranged in the cavity (4) of the coupler head, comprising a lock (5), a sensing lever (16), an intermediate lever (13), and a pull rod (22), all such elements being movable essentially in horizontal planes only ; - the lock (5) and the sensing lever (16) being loaded to the front by springs (10, 20) in moving direction ; the intermediate lever (13) and the sensing lever (16) being separately pivoted to a common vertical bolt (14) laterally of the lock (5) ; - the intermediate lever (13) being engageable with the lock (5) and the sensing lever (16) and being disengageable from the lock (5) by the pull rod (22), in engaging direction being loaded by a spring (21) and in acting direction of the spring (21) being interceptable by a stop (19) at the sensing lever (16) ; - the intermediate lever (13), with the sensing lever (16) assuming a position corresponding to the opposite coupler head being in place, being engageable by spring force against the locking force of lock (5) behind a first stop face (7) in a front coupling position of the lock (5) and in front of a second stop face (9a) in a rear uncoupling position of the lock (5) said stop surfaces extending from the latter in lateral direction, and, with the sensing lever (16) assuming a position corresponding to the opposite coupling head being out of place, being disengaged from the stop surfaces (7, 9a) of the lock (5), and, - starting from the coupled position, the pull rod (22), when being returned from its normal to an uncoupled position, during a first stroke portion, rotating the intermediate lever (13) out of its engaged position with the first stop face (7), possibly before the end of such stroke portion, and, in any case, during a further stroke portion, engaging the lock (5), taking the latter along, and - the pull rod (22), applying the wall (25), associated to the latter, to the intermediate lever (13), rotating the latter immediately out of its engaged position with the first stopping face (7), and - the intermediate lever (13), until engaging in front of the second stop face (9a), being applied to by spring force and sliding alongside the flank (26) of the lock (5), which moves backward.
