Abstract

There is provided a lock device which is adapted to hold a lid member 3 with a lock 8 at a counterpart of a main body 1 in a closed state, which comprises an operating button for an unlocking operation 9; a slidable engagement member 11 having an engageable portion 14, the engageable portion being configured to be selectively brought into engagement with and out of engagement with the main body 1; and a coupling member 20 configured to interlock the operating button 9 and the engagement member 11 with a locking operation and the unlocking operation applied to the lock 8 so that the operating button 9 and the engagement member 11 are set in an interlocked state by the unlocking operation and are set to be free of the interlocked state by the locking operation; whereby the engagement member 11 is slid through the coupling member 20 to bring the engagement member 14 out of engagement with the main body 1 so as to be switched to an open state by operating the operating button 9 when the lock 8 is set in an unlocked position.

Claims

1. A lock device which is adapted to hold a lid member with a lock at a counterpart of a main body in a closed state, comprising:

an operating button for an unlocking operation;

a slidable engagement member having an engageable portion, the engageable portion being configured to be selectively brought into engagement with and out of engagement with the counterpart of the main body; and

a coupling member configured to interlock the operating button and the engagement member with a locking operation and the unlocking operation applied to the lock so that the operating button and the engagement member are set in an interlocked state by the unlocking operation and are set to be free of the interlocked state by the locking operation;

whereby the engagement member is slid through the coupling member to bring the engagement member out of engagement with the main body by operating the operating button when the lock is set in an unlocked position.

2. The lock device according to claim 1, wherein the coupling member is supported so as to be slidable in a direction substantially orthogonal to a depressing direction of the operating button, and the engagement member is supported so as to be slidable in substantially the same direction as the depressing direction of the operating button.

3. The lock device according to claim 1, further comprising a rotor rotated by each of the locking operation and the unlocking operation applied to the lock, and an arm disposed on the rotor, whereby the arm is operatively coupled to one end of the coupling member to slide the coupling member in synchronization with rotation of the rotor.

4. The lock device according to claim 1, wherein the engagement member has the engageable portion disposed at least two positions in a sliding direction.

5. The lock device according to claim 1, further comprising a biasing member for returning the operating button to an original position after the operating button is operated, and another biasing member for returning the engagement member in a direction to bring the engageable portion into engagement with the counterpart of the main body.

6. The lock device according to claim 1, wherein the main body is a console box, and the lid member is swingably coupled to the console box at one end thereof in a longitudinal direction thereof and has the engagement member disposed along the other end in the longitudinal direction.
