ABSTRACT:
A power-driven automobile door locking device of the type wherein a latch engages and arrests a striker on the door. The device has a lock lever capable of assuming a locking position in which the latch is not releasable and an unlocking position in which the latch is releasable. The lock lever is moved by a motor between the locking and unlocking positions. The motor drives a rotary disk in rotation, which disk has an essentially spiral cam groove in the surface thereof. A cam follower engages with the spiral cam groove, and, as the disk is rotated, the cam follower is caused to move radially of the disk, the radial movement of the cam follower is transmitted to the lock lever through any suitable mechanism. The spiral groove operates to transmit an amplified force to the cam follower. The rotary disk may be replaced by a rotary cylinder having a cam groove in its cylindrical surface. A modified cam groove is defined by an action-imparting or camming side edge and a non-action-imparting or non-camming side edge, and the groove has the greatest width at its mid-portion.
