Abstract

A vehicle lock device includes a base member, a latch, and a release lever. The base member includes a base groove, into which a striker is inserted. The latch includes a latch groove into which the striker is inserted. The latch is pivotal between a lock position, where the striker is fixed to the base groove, and an unlock position, where the striker is released from the base groove. The release lever is pivotal between a lock release position, where pivoting of the latch is permitted from the lock position to the unlock position, and a restriction position, where pivoting of the latch is restricted from the lock position to the unlock position. The release lever includes an engagement release member that contacts the latch when pivoted from the restriction position to the lock release position to pivot the latch from the lock position to the unlock position.

First claim

The invention claimed is:

1. A vehicle lock device comprising:
a base member including a base groove, into which a striker fixed to one of a stationary member and a movable member is inserted, wherein the base member is fixed to the other one of the stationary member and the movable member;
a latch pivotally connected to the base member, wherein the latch includes a latch groove into which the striker is inserted, and the latch is pivotal between a lock position, at which the striker is fixed to the base groove, and an unlock position, at which the striker is released from the base groove; and
a release lever pivotally connected to the base member, wherein the release lever is pivotal between a lock release position, at which pivoting of the latch is permitted from the lock position to the unlock position, and a restriction position, at which pivoting of the latch is restricted from the lock position to the unlock position, and the release lever is pivoted from the restriction position to the lock release position by a lock release operation,
wherein the release lever includes an engagement release member that moves into contact with the latch and presses the latch to pivot the latch from the lock position to the unlock position as the release lever pivots from the restriction position to the lock release position.

2. The vehicle lock device according to claim 1 , further comprising a cam member pivotally connected to the base member and engaged with the latch at the lock position, wherein when the latch is located at the lock position and the release lever is pivoted from the restriction position to the lock release position, the release lever contacts the cam member and releases the engagement of the cam member and the latch.

3. The vehicle lock device according to claim 2 , wherein when the release lever is pivoted from the restriction position to the lock release position, after the engagement of the cam member and the latch is released, the release lever brings the engagement release member and the latch into contact to pivot the latch to the unlock position.

4. The vehicle lock device according to claim 1 , wherein
the latch is configured to be in an engagement state engaged with the release lever at a middle position from when pivoting of the latch is started by the engagement release member from the lock position toward the unlock position to when the latch reaches the unlock position, and
the release lever restricts pivoting of the latch to the lock position in the engagement state.

5. The vehicle lock device according to claim 1 , wherein the latch includes a latch projection projecting from a surface of the latch in a thickness-wise direction of the latch, and the release lever presses the latch at the latch projection.
