The motor 203 transmits its rotational movement by means of a speed reducer with a freewheel 214 which, in one direction, drives a cam 213, the step 213a of which causes a finger 236 to lift the tooth 234a of a ratchet 234, said tooth cooperating with a rotary bolt 225 subjected to the action of a spring 256, thereby ejecting the keeper 240 out of the bolt housing 214 as a result of the power of the spring 256 and of the rotation of the bolt 225, whilst the opposite movement of the motor 203, controlled by a microswitch 250 and by means of an intermediate pinion 216, a second free wheel 220 and a shaft 221, allows, by way of a suitable speed reducer, the rotation of the driver 222, the rotation of the bolt 225 in the closing direction and thus the correct placing of the keeper 240 into its locking position within the bolt housing 241. <IMAGE> |
