Abstract (en)
[origin: US4742200A] For cocking an energy accumulator, an actuating device comprises a ratchet wheel with teeth as well as a reciprocating transport ratchet. For maintaining the cocked position of the energy accumulator, a cam wheel and blocking lever which can be braced against a blocking member via a ratchet lever are provided. Due to a wedge-like cooperation between a working surface of the cam wheel and a projection of the blocking lever, the blocking lever is transferred from its rest position into a blocked position if the deadcenter position of the cam wheel is exceeded. In the process, the transport ratchet is lifted from the teeth of the ratchet wheel by means of a striking surface of the blocking lever.
