Abstract
An electric lock for remote access control to a container wherein a U-shaped latch is mounted on a door in alignment with a slot in a housing mounted in the container. Upon closure, the latch enters the housing to engage a slotted keeper therein and causes rotation of the keeper. Rotation of the keeper causes a release lever to engage a stepped protrusion on the keeper and secures the keeper and latch. Activation of a solenoid or drive motor coupled to the release lever permits withdrawal of the latch from the housing. The axes of rotation of the keeper and release lever are located to greatly reduce the impact of pre-release forces to the door.
Claims14
A locking device for receiving a latch having a locked and unlocked position, said device comprising:
- (a) a housing configured for receiving said latch therein;
- (b) a keeper having a receiving slot for releasably engaging said latch, said keeper further including an engagement feature;
- (c) a releasing lever rotationally disposed about an axis, said releasing lever including an arc shaped surface that is concentric to the rotational axis of said releasing lever;
- and
- (d) an actuator coupled to the releasing lever, said actuator configured for selectively permitting rotation of said keeper to the unlocked position,
- wherein said engagement feature engages said arc shaped surface in the locked position, wherein engagement of said engagement feature and said arc shaped surface inhibits said keeper upon receipt of said latch in said receiving slot thereby establishing the locked position, and wherein said arc shaped surface is configured for enabling said locking device to assume the unlocked position by an activation of said actuator when a pre-release load is applied to said keeper by said latch.
A locking device for receiving a latch having a locked and unlocked position, said device comprising:
- (a) a housing configured for receiving said latch therein, wherein an opening is defined in said housing;
- (b) a keeper having a receiving slot for releasably engaging said latch, wherein said receiving slot is aligned with said opening in the unlocked position, said keeper further including an engagement feature;
- (c) a releasing lever rotationally disposed about an axis, said releasing lever including an arc shaped surface that is concentric to the rotational axis of said releasing lever;
- (d) a biasing member comprising a single spring having a first end and a second end, said first end engaging said keeper for urging said keeper to align the receiving slot with said opening, said second end engaging said releasing lever for urging said releasing lever into engagement with said keeper;
- and
- (e) an actuator coupled to the releasing lever, said actuator configured for selectively permitting rotation of said keeper to the unlocked position,
- wherein said engagement feature engages said arc shaped surface in the locked position, and wherein engagement of said engagement feature and said arc shaped surface inhibits said keeper upon receipt of said latch in said receiving slot thereby establishing the locked position.
