Door lock device with automatic closing mechanism
First Claim
1. A door lock device with an automatic door closing mechanism, comprising:
- a lock body having a front surface side formed therein a recess substantially covered by a metal plate;
a spring returned type latch adapted to be engaged with a striker fixed to a vehicle body so as to be rotated from an open position to a full-latch position by way of a half-latch position;
a ratchet adapted to be engaged with the latch so as to hold the engagement between the latch and the striker;
an actuator adapted to be operated when the latch is rotated to the half-latch position;
an output lever adapted to be rotated by power of the actuator; and
a link lever which is rotated in association with any rotation of the output lever so as to move the latch from the half-latch position to the full-latch position;
wherein said latch, said ratchet and said link lever are stored in said recess of said lock body, and said output lever is provided on the rear surface side of the lock body, andsaid link lever is rotatably attached to a slide member having a roller abutting an outer periphery of said latch to allow said roller to press and move said latch when said link lever is rotated.

6. A door lock device with an automatic door closing mechanism, comprising:
-
a latch adapted to be engaged with a striker fixed to a vehicle body so as to be moved from an open position to a full-latch position by way of a half-latch position; a latch adapted to be engaged with said ratchet so as to hold the engagement between the striker and the latch; an actuator adapted to be operated when said latch is rotated to the half-latch position; an output lever adapted to be rotated around a first shaft by power of the actuator; a link lever adapted to be rotated in association with the rotation of the output lever so as to move the latch from the half-latch position to the full-latch position; an open lever coupled to an open handle of a door, for releasing said ratchet from the latch when it is rotated; and a movable rod journalled rotatably to the open lever by means of a second shaft laid coaxially with said first shaft, and connecting the output shaft with the link lever; whereby said movable rod is adapted to be moved in association with a shift of the center axis of the second shaft from the center axis of the first shaft upon rotation of the open lever so as to release the engagement between the output lever and the link lever. - View Dependent Claims (7)
