Abstract
A collinear latching and locking system is disclosed. In embodiments, the system includes a strike with a lock bolt disposed at or defined by an end of the strike. The system further includes a latch pawl configured to surround at least a portion of the strike. The strike and the latch pawl are configured to actuate linearly along the same axis. In this regard, the strike and the latch pawl have a collinear configuration and actuation path. The system further includes a latch cam configured to actuate the latch pawl from a latched position to an unlatched position when the latch cam is turned.
Claims17
A door securing device, comprising:
- a strike with a lock bolt disposed at or defined by an end of the strike, the strike configured to actuate linearly along an axis;
- a latch pawl configured to surround at least a portion of the strike and linearly actuate along the same axis as the strike;
- a housing that defines a cavity configured to house at least a portion of the strike and at least a portion of the latch pawl;
- at least one spring disposed at least partially within the housing, the at least one spring configured to bias the latch pawl towards a latched position;
- a latch cam disposed at least partially within the housing, the latch cam configured to actuate the latch pawl towards an unlatched position when the latch cam is turned;
- a handle coupled to the latch cam and configured to turn the latch cam;
- and
- a lock trigger coupled to the strike for linearly actuating the strike between locked and unlocked positions,
- wherein the strike includes an opening configured to surround at least a portion of a latch leaf that extends from the latch cam so that the latch leaf is disposed within a first portion of the opening when the strike is in the unlocked position and within a second portion of the opening when the strike is in the locked position.
