A lock device that prevents operation of at least one chassis spindle from retracting a latch bolt, and which may provide auto-unlock features. Locking of the lock device can effectuate linear displacement of a slider body from an unlocked position to a locked position. Linear displacement of the slider body is translated into rotational displacement of a cam body that includes, or is coupled to, a locking shaft having a cam protrusion, thereby rotating the cam protrusion. As the cam protrusion rotates, the cam protrusion lifts a locking lug to a locked position wherein the locking lug prevents rotational displacement of a first chassis spindle. When in the locked position, a slider arm of the slider body can be positioned in a retention slot. Subsequent rotable displacement of a second chassis spindle can effectuate displacement of the slider arm from the retention slot and facilitate unlocking of the lock device.

Provided is a door lock mortise. The door lock mortise includes a structure in which a latch fixing member moves between a latch operating member and a latch cover member when a dead bolt is locked or unlocked. According to the embodiments of the present invention, the door lock mortise including the latch fixing member to have a structural characteristic capable of addressing a problem in that a latch bolt may be moved when the dead bolt is unlocked to release a door lock so that an impact is transmitted only to the dead bolt in a state in which the dead bolt is not unlocked and durability is reduced is disclosed.

A locking device comprises a latch, a spindle and a rotary assembly. The latch is fixed to an object to be locked for engaging with a bore of a strike; the latch has a bolt which locks the object. One end of the spindle is detachably connected to the latch to drive the bolt to move towards or away from the bore. The rotary assembly is disposed at the other end of the spindle, which comprises a cylinder body and a rotary body, the cylinder body is rotated by the rotary body as it rotates, wherein one end of the rotary assembly is provided with a spindle driving means engaged with the other end of the spindle to drive the spindle to rotate. The rotary assembly drives the spindle to rotate via the spindle driving means, and the spindle drives the bolt to move approaching the bore to realize locking.

A vehicle that includes a door, handle, shaft, and a latch assembly is provided. The latch assembly is coupled to the door to selectively secure the door. The latch assembly includes a security tether configured to prevent the shaft from moving the pawl when the lock lever is located in the locked condition. The security tether further includes: a plate attachable to the latch assembly; the plate includes an aperture sized to receive at least a portion of the lock lever that is disposed through the aperture; the plate includes first and second stop surfaces to limit movement of the lock lever; the first and second stop surfaces are also spaced apart from each other; the lock lever is movable between the first and second stop surfaces; at least the first stop surface is spaced apart from the first location on the pawl; and the lock lever engages the first stop surface when the lock lever is located in the locked condition to prevent the pawl from moving to the unlatched condition and unlatching the latching assembly.

The present invention relates to the field of lockset and provides a lock body a latch bolt installation structure comprising a latch bolt body having a driving part and a latch part, wherein the latch part is detachably connected with the driving part. The latch part is configured with a male part inserting into a female part on the driving part; the female part comprises a first installation position and a second installation position for installing the latch part; when the latch part is installed at the first installation position, a flat surface of the latch part faces towards a first direction; when the latch part is installed at the second installation position, the flat surface of the latch part faces towards a second direction which is opposite to the first direction. The present invention is advantageous in fast reversal of the installation of the latch bolt as well as the construction progress control and user experiences.

A latch mechanism includes a hook-handle assembly coupled to a first panel and a clevis coupled to a second panel. The hook-handle assembly engages the clevis to secure the first panel relative to the second panel.

A wirelessly controlled blocking apparatus to enable a single-point locking system for securing multiple access points on a cabinet panel. Certain aspects of the present disclosure provide for a wirelessly controlled blocking apparatus to enable a single-point locking system for securing multiple access points. In accordance with certain embodiments, the wirelessly controlled blocking apparatus is utilized to secure an access panel of an enclosure, such as an electronics cabinet. In accordance with certain preferred embodiments, an electronics cabinet comprises a plurality of quarter-turn cam latches being installed on the access panel and configured to selectively secure the access panel to an opening of the enclosure.

A panel lock includes a shell, a rotating shaft, a locking tab, a handle, a latch hook and a first elastic spring. The rotating shaft is rotatably mounted in the shell. The locking tab is connected to and rotates along with the rotary shaft to realize unlocking and locking. The handle is rotatably mounted to the rotating shaft, and has a first position being folded and a second position being lifted during rotation about a first axis perpendicular to the rotating shaft. The handle includes a latching groove and a guiding portion arranged at a side of the latching groove. The latch hook is rotatably mounted in the shell. The first elastic spring is arranged between the latch hook and the shell. Automatic locking of the handle can be realized during the movement of the handle from the second position to the first position.

A lever-operated latch device includes an assembly of a case body, an actuation body mounted on the case body, a linking member and a slide body. The actuation body has a free end and a pivoted end pivotally connected with the case body in cooperation with elastic members. The free end of the actuation body is formed with two protruding arms and an opening section positioned between the protruding arms. An operation section is disposed in the opening section. The linking member has a first end pivotally connected with the free end of the actuation body (or the operation section) and a second end connected with the slide body. When an operator presses the operation section, the actuation body is permitted to move from a closed position to an opened position so as to drive the linking member and the slide body to move.

A keycam assembly including a rotatable member, a stem, a locking member coupled to the stem for joint longitudinal movement therewith, and a cam driver. The rotatable member includes an aperture. A proximal end portion of the stem is rotatably seated in the rotatable member and defines a cam track. The locking member extends between the aperture and the cam track. The cam track includes a first passage including a locking pocket, a second passage including an unlocking pocket, a first ramped passage including a locking ramp extending from the second passage to the locking pocket, and a second ramped passage including an unlocking ramp extending from the first passage to the unlocking pocket. Relative rotation of the rotatable member and the stem causes the cam driver to travel along the track to thereby cause movement of the locking member between a locking position and an unlocking position.
