Door lock device with automatic closing mechanism

摘要

A door lock device with an automatic door closing mechanism comprises a lock body (3) having a recess (5) on its front surface side, a latch (6) adapted to be engaged with a striker (2) so as to be rotated from an open position to a full-latch position (Figure 4, not shown) by way of a half-latch position (Figure 3), a ratchet (11) adapted to be engaged with the latch (6) so as to hold the engagement between the latch (6) and the striker (2), an actuator adapted to be operated when the latch (6) is rotated to the half-latch position, an output lever (38) adapted to be rotated by power of the actuator, and a link lever (28) adapted to be rotated by rotation of the output lever (38) so as to move the latch (6) from the half-latch position to the full-latch position. The latch (6), the ratchet (11) and the link lever (28) are stored in the recess (5) of the lock body (3), and the output lever (38) is provided on the rear surface side of the lock body (3). In order to cope with an accident provision is made such that the power to the actuator may be cut off when the open handle (56, not shown) on the door is manipulated.
