Abstract

The invention relates to a safety ratchet device (10) for preventing an undesired relative movement of two members (4/2,3;25/21,22) movable relative to one another in a lengthwise direction. The device comprises a series of successive stop elements (15;27) in the longitudinal direction each defining a stop surface (15;28) in a plane transversely of the longitudinal direction on the one member (2,3;25), a support surface (13;30) on the other member (4;21,22) facing toward the stop surfaces (15;28), a ratchet element (12;31) which lies loosely with one end (14;39) against the support surface (13;30) and which is pivotable between a slanting position in which another end can come into contact with a stop element and a retracted position in which the stop elements can pass freely, and urging means (16,33) for urging the ratchet element into the retracted position counter to a bias. <IMAGE>
