Abstract
A drawer apparatus capable of locking and unlocking a drawer without position control and motor stop control is provided. A lock frame is released from the hook to be brought into an operable state by unidirectional rotation of a DC motor in an engaged state. A drawer is released from an anchor to be advanced out of the retracted position when the lock frame operates. A planetary gear unit is pushed by the lock frame. A small-diameter planetary gear is thereby shifted from the engaged state to a default state. The anchor is engaged with the drawer when the advanced drawer is pushed back to the retracted position. The hook is engaged with a lock when the advanced drawer is pushed back to the retracted position.
Claims16
A drawer apparatus comprising:
- a drawer urged in an advancing direction when the drawer is disposed in a retracted position:
- a hooker having a hook and a gear;
- a motor:
- a transmitter to be shifted from a default state to an engaged state by rotation of the motor, the transmitter being provided with a transmission gear which is separated from the gear in the default state while engaged with the gear in the engaged state to be rotated by torque of the motor;
- and
- a locker provided with a lock to be engaged with the hook in a locked state and with an anchor to be engaged with the drawer in the retracted position in the locked state;
- wherein the locker is released from the hook to be brought into an operable state when the motor is rotated in one direction in the engaged state;
- wherein the drawer is released from the anchor to be advanced out of the retracted position when the locker is brought into the operable state;
- wherein the transmitter is pushed by the locker in the operable state;
- wherein the transmission gear is shifted from the engaged state to the default state when the transmitter is pushed by the locker in the operable state;
- wherein the anchor is engaged with the drawer when the advanced drawer is pushed back to the retracted position;
- and
- wherein the hook is engaged with the lock when the advanced drawer is pushed back to the retracted position.
