LOCK RELEASE MECHANISM

摘要

A lock release mechanism connected to a lock mechanism via a cable (15) and capable of releasing a locked state of the lock mechanism by electrically pulling the cable (15). The lock release mechanism (1) has a manually operated main switch (2), a motor (3) driven by electricity supply operation by the main switch (2), a conversion gear mechanism (4) for converting the direction of output of the motor (3), conversion means (5) for converting rotational motion to reciprocating linear motion, a slider (6) to which the cable (15) is connected and reciprocating linearly, and a limit switch (7) capable of supplying electricity to the motor (3) by a parallel circuit different from an electricity supply circuit of the main switch (2). The limit switch (7) interrupts supply of electricity when the slider (6) is at a neutral position. On the other hand, the limit switch (7) is held at an electricity supply state while the slider (6) reciprocates one time, and the slider (6) is held at a full stroke position for a predetermined time.
