The present application provides a lock (100) for a door. The lock comprises a housing (102), a lock mechanism (108), and a bolt (104). An end portion (112) of the bolt comprises a trigger (106). The lock mechanism is operable to move the bolt between a locked position in which the end portion extends through an opening in the housing and projects from the housing, and an unlocked position in which the end portion is within the housing. The lock further comprises a retraction mechanism (110), wherein actuation of trigger causes the retraction mechanism to automatically move the bolt from the locked position into the unlocked position.

Apparatus and associated methods relate to an access control system having a planar interlocking mechanism including two reflectively symmetric rotating moon gears mechanically coupled by a linear slide configured to respond to rotation of the moon gears. In an illustrative example, the moon gears are mechanically coupled by the linear slide via respective actuating cams. The moon gears may be provided, for example, with locking cams configured to releasably secure the linear slide via a corresponding follower on the linear slide. Rotation of one moon gear into a first mode may, for example, place the other moon gear in a second mode, and vice versa. Each moon gear may be configured, for example, to be operated by a removable peg. Various embodiments may advantageously be configured such that release of a removable peg from one moon gear captures a peg in a corresponding moon gear.

The disclosure relates in general to a deadbolt latching mechanism for a door. Specifically, the disclosure relates to a fortified deadbolt latch providing fortification against attempted prying of a door against the locking mechanism. A fortified deadlock latch device configured to reversibly move between an extended locked and retracted unlocked position, the device comprising: a. a latch housing having a longitudinal axis; b. a latching assembly, the latching assembly slidably coupled to the latch housing along the longitudinal axis; c. a bolt assembly coupled to the latching assembly, the bolt defining a circumferential surface; d. a rocker hingedly coupled to the bolt assembly, the rocker having a proximal end and a distal end, wherein, the distal end is configured to protrude beyond the bolt assembly's circumferential area and engage a frame jamb box in the extended position; and e. a bolt sleeve or a face plate, operably coupled to the latch housing.

Latch assemblies and systems are disclosed. One latch includes a latch and a receiver. The latch has a housing and a pin extending from the housing. The pin is mounted for longitudinal movement along a pin axis. The latch further includes a motor coupled to move the pin longitudinally. The receiver defines an aperture extending along a receiver axis and positioned to receive the pin of the latch. The receiver has a retainer biased toward the receiver axis. The latch assembly has an open position in which the pin is extended distally along the pin axis and received in the aperture, and a latched position in which the pin is retracted proximally along the pin axis while the retainer is engaged with the pin. One latch system includes a plurality of latch assemblies configured to move to the latched position after all latch assemblies are in the open position.

Cylinder assembly with rotating winged latch bolt for sliding door lockset includes a special latch bolt that holds in an extended position and holds in a retracted position which alternates back and forth by pressing the latch bolt with your finger. The special latch bolt rotates ninety degrees by turning the doorknob, door handle, thumb turn, or coin turn and rotates back ninety degrees by turning the doorknob, door handle, thumb turn, or coin turn back. The special latch bolt has a special winged shape that catches within the strike plate when rotated ninety degrees and releases from the strike plate when rotated ninety degrees back. Also there is a special face plate or cylinder face plate with tabs or notches that serve as a two-position mechanical stop to prevent the latch bolt from over rotating beyond ninety degrees in either direction.
