Title:
LOCKING DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/052540
Kind Code:
A1
Abstract:
Disclosed is a locking device provided with a hook capable of being rotated to a locking position where a striker is held, a release position where the striker is released, and an over-stroke position which is located beyond the locking position; and a ratchet capable of being rotated to an anchor position wherein the hook is held in the locking position and an anchor release position wherefrom the hook is allowed to rotate to the release position. The locking device is also provided with an electric rotation control means for controlling the rotation of the hook and ratchet by driving a motor. When the hook and the ratchet are transitioning from an anchor release state to an anchor state, the electric rotation control means simultaneously holds the hook and the ratchet in the over-stroke position and the anchor release position, then causes the ratchet to rotate to the anchoring position, with the hook held in the over-stroke position, and subsequently causes the hook to rotate to the locking position. By means of the locking device, it is possible to mitigate the collision between the hook and the ratchet during locking operation, thereby improving quietness.
