Abstract
A lock mechanism having a bolt movable between a thrown position and a retracted position, and a deadbolt assembly includes a sliding deadbolt configured to slide between a locked position in which the sliding deadbolt inhibits retraction of the bolt and an unlocked position. The sliding deadbolt includes a first anti-thrust cam configured to restrain the sliding deadbolt in the locked position, and a release driver arranged such that, when driven, the release driver releases the first anti-thrust cam from restraining the sliding deadbolt in the locked position and slides the deadbolt to the unlocked position.
Claims24
A lock mechanism, comprising:
- a bolt movable between a thrown position and a retracted position;
- and a deadbolt assembly comprising:
- a sliding deadbolt configured to slide between a locked position in which the sliding deadbolt inhibits retraction of the bolt and an unlocked position, the sliding deadbolt comprising a first anti-thrust cam configured to restrain the sliding deadbolt in the locked position, and
- a release driver arranged such that, when driven, the release driver releases the first anti-thrust cam from restraining the sliding deadbolt in the locked position and slides the deadbolt to the unlocked position wherein the first anti-thrust cam is a receiver and the deadbolt assembly is a detent attached to a casing part of the deadbolt assembly, and when the first anti-thrust cam restrains the sliding deadbolt in the locked position the receiver engages the detent.
A lock mechanism, comprising:
- a bolt movable between a thrown position and a retracted position;
- and a deadbolt assembly comprising:
- a sliding deadbolt configured to slide between a locked position in which the sliding deadbolt inhibits retraction of the bolt and an unlocked position, the sliding deadbolt comprising a first anti-thrust cam configured to restrain the sliding deadbolt in the locked position and a second anti-thrust cam pivotably coupled to the sliding deadbolt and configured for rotational movement in cooperation with the first anti-thrust cam, and
- a release driver arranged such that, when driven, the release driver releases the first anti-thrust cam from restraining the sliding deadbolt in the locked position and slides the deadbolt to the unlocked position.
A deadbolt assembly, comprising:
- a sliding deadbolt configured to slide between a locked position in which the sliding deadbolt inhibits retraction of a further bolt and an unlocked position, the sliding deadbolt including (a) a first anti-thrust cam configured to restrain the sliding deadbolt in the locked position, (b) a second anti-thrust cam pivotably coupled to the sliding deadbolt and configured for rotational movement in cooperation with the first anti-thrust cam, and (c) a release driver arranged such that, when driven, the release driver releases the first anti-thrust cam from restraining the sliding deadbolt in the locked position and slides the deadbolt to the unlocked position.
