  • Patent number: 5232253
    Abstract: A power-closing vehicle door lock device comprises a spring-returned latch rotatably mounted on a base plate and having a U-shaped groove for engaging a striker, a spring-returned ratchet rotatably mounted on the plate and engaged to the latch after the latch rotates to a closed-lid position thereby preventing the latch from rotating to an open-lid position, a pressing link slidably engaged to the latch for rotating the latch to the closed-lid position from the open-lid position, an open lever rotatably engaged to the ratchet for reliefing the ratchet from the latch and permitting the latch to rotate to the open-lid position, an actuator for moving the pressing link to rotate the latch into the closed-lid position when moving in a first direction and rotating the lever to permit the latch to rotate to the open-lid position when moving in a second direction, a manual-open handle connected to the lever, and a deformed oval opening formed in the lever so as to guide motion of the pressing link.

  • Patent number: 5180198
    Abstract: An electric driven type lock device used to a car trunk lid has a striker, a latch, and a ratchet for preventing the latch from reverse-rotating. When the striker reaches its position confronting a U-shaped groove or notch formed in the latch, a motor makes the pressing link rotate forcibly in a closed-lid direction. An electric-driven-condition relief link is connected to the ratchet. When the motor reversely rotates, the electric-driven-condition relief link makes the ratchet leave from the latch. Further, the lock device has a manual relief lever which to lever the pressing link and the ratchet are connected. When the manual relief lever is operated, the pressing link is left from a rotation track of the latch, as well as the ratchet is left from the latch.
