Abstract: A locking device of a hood for a ventilator window in an automobile which comprises a hood mounted to be opened and closed in the ventilator window formed in the ceiling of a vehicle and able to be opened and closed by operating a controlling lever in a car body and also closed by manually depressing the hood from outside of the vehicle but unable to be opened manually from outside of the vehicle.

Abstract: This automobile locking apparatus includes a one-piece, molded, plastic body having a pivotal door latch and associated ratchet pivotally mounted in a recess in one side thereof and a cooperating release lever and locking lever pivotally mounted, respectively, on a pair of integral sleeves which project from the opposite side of said body coaxially of the pivot axes of said latch and ratchet. A link which interconnects the release and locking levers, respectively, is engageable with a pin on the ratchet to prevent the locking lever to be swung into a locking position except which the release lever has been swung to a door-opening position.

Abstract: A latch member or rotor is rotatably mounted in a main body or frame, attached to a vehicle door, for engaging a striker affixed to the vehicle body. Also mounted in the main body, in coplanar relation to the latch member, is a ratchet engageable with the latter to inhibit its motion in a direction to disengage the striker. The main body has an upstanding bracket on which three levers are mounted for pivotal motion about a common axis, in planes perpendicular to the plane of the latch member and the ratchet. The three levers are: (1) an actuating lever acting directly on the ratchet to cause the same to disengage the latch member and hence to unlatch the door; (2) an outside release lever linked to an outside door handle; and (3) an inside release lever linked to an inside door handle. These levers are interrelated in such a manner that the latch member releases the striker upon actuation of either the outside or the inside door handle.

Abstract: A latch device having a locking mechanism is locked and unlocked by a lock operating device comprising: a lock lever coupled to and operating the locking mechanism when driven to undergo displacement between terminal lock and unlock positions; a motor for driving the lock lever; a retaining member exerting an elastic force (1) to cause the lock lever to undergo the displacement with a click motion, over-riding an intermediate dead-center point against an elastic resistance and (2) to retain the lock lever positively in either terminal position after each displacement; and a retraction device for temporarily nullifying or greatly reducing the action of the retaining member at the time of the displacement of the lock lever.
