Abstract
Provided is an opening/closing apparatus with a lock capable of performing the opening/closing and closed lock of a sliding door by a single actuator and arbitrarily setting the timing of a lock operation. In the opening/closing apparatus with a lock, an electric motor is driven and the drive force of the electric motor is input to the sun gear of a planetary gear mechanism and output from the internal gear or the carrier. A pair of sliding doors are opened and closed by the drive force output from the internal gear. While the pair of sliding doors are at a fully closed position, the lock and lock-released states of a lock mechanism are switched by a lock restricting mechanism.
Claims7
An opening and closing apparatus with lock, comprising:
- a pair of slide-apart type sliding doors movable reciprocatingly with respect to a housing;
- a pair of opening/closing drive mechanisms each mounted on a corresponding one of the pair of slide-apart type sliding doors;
- an actuator configured to drive the pair of opening/closing drive mechanisms;
- one input two output mechanism having an input portion into which a drive force of the actuator is input and a first and second output portions each capable of outputting the drive force;
- a locking mechanism mounted on the housing, wherein the locking mechanism is configured to lock the pair of sliding doors by constraining movement of locking members each fixed to corresponding one of the pair of sliding doors in response to outputs from the first and second output portions;
- and
- a lock restricting mechanism configured to restrict, based on an external signal, switching of the locking mechanism from a lock-released state to a locked state while the pair of sliding doors are at a fully closed position.
