A method of using the assembly is also provided.

A multi-axial catch comprises a mount and a catch body coupled to the mount. The mount affixes the catch to a frame and the catch body has a recess to position a latch head of a latch within the recess to engage the latch with the catch. The catch can include a cam to form the recess. The catch rotates around a rotation axis in response to a longitudinal motion of the latch. The catch body is coupled to the mount to allow the catch body to rotate around a pivot axis in response to a transverse motion of the latch. The catch includes an elastic coupler to position the catch in a rotational at-rest position and an elastic coupler to position the catch-body in a transverse at-rest position. The recess allows the latch head to move laterally, in response to a lateral motion of the latch, within the catch.

A lockable latch (8) is disclosed for walk-in cold rooms which includes a lockable strike (10) with an exterior strike assembly (16) and an interior release assembly (17). The exterior strike assembly includes a housing (25) and a rod holder (32) configured to releasably hold a coupling rod (35). The exterior strike assembly also has a metal anti-rotation plate (40) removably coupled to the housing. The interior release assembly includes a turn knob (53), an escutcheon plate (54), and an index washer (55). The turn knob includes two oppositely disposed alignment projections (77) and a radial array of steps (78) which includes four, re-occurring series of three steps. The index washer has a four time re-occurring series of steps (93).

An exit device according to one embodiment includes a plurality of sensors and an electronic dogging mechanism. The exit device is configured to locally analyze sensor data to determine the security state of the exit device, report data to a management system via a wireless communication channel established between the exit device and the management system, and receive and process instructions to perform an electronic dogging operation.

The invention provides a covered dustbin or covered container. In particular, the invention relates to a lock assembly for dustbins and covered containers. A lower half of the lock is mounted to the inside wall of the dustbin and an underlid half is mounted to the underside of a lid that is hinged to a location adjacent the upper rim of the dustbin. A pair of interlocking engagement members is provided to releasably secure the lid to the dustbin. The lower half and the underlid half each include one interlocking engagement member, such as a hook and a strike. A rocker, when actuated, urges the interlocking engagement members into a disengaged position, for example to disengage the hook from the strike. A user can use a handle provided on the lid to press down the rocker to disengage the lock and lift the lid in a one-hand operation.

A vertical door latch assembly includes a bolt that has a catch portion located adjacent a distal end of the bolt. A latch has a retention feature for engaging the catch portion of the bolt. An electro-mechanical locking assembly secures the latch between a locking position preventing movement of the bolt and a non-locking position allowing movement of the bolt. A controller is in electrical communication with the electro-mechanical locking assembly and is configured to direct the electro-mechanical locking assembly between the locking position and the non-locking position.

This invention discloses a lock that set on a suitcase of being opened or closed without using a zipper, which including an operating component and a locking component that are separately-mounted; the operating component is set on a non-border position of the suitcase, and the locking component is set on the border of the suitcase, wherein the locking component comprises at least one locking unit, the force transfer between the operating component and the locking component is provided by a force transmission mechanism that connected between the operating component and the locking component; the operating component comprises an operation member, and the locking unit comprises a lock head and a lock hook, wherein driving the operation member can drive the lock head or the lock hook to move through the force transmission mechanism, to lock or unlock the lock. This invention also provides a suitcase provided with the lock as described above. This invention set the operating component and the locking component separately, which solves the problem that the lock can only be installed on the border of the suitcase, and only the locking component needs to be installed on the border of the suitcase, while the operating component can be installed at any position of the suitcase other than the border.

A door for utility vehicle including a door body part provided with a grip part used for opening and closing the door. The door body part is supported by a vehicle body frame in a manner of being capable of being set at a plurality of closed states each having a different gap between the door body part and the vehicle body frame.

An electronic device includes a first unit, a second unit, and a lock mechanism. The lock mechanism includes: an engagement projection provided on a third side surface of the first unit; a latch provided on a fourth side surface of the second unit, the latch being rotatable around a rotation axis provided perpendicular to the fourth side surface between a first rotational position where the latch does not engage with the engagement projection and a second rotational position where the latch is engageable with the engagement projection, and an urging member that urges the latch to be positioned at the second rotational position. The latch has an inclined part. When the latch is located at the second rotational position and the first unit is changed to a closed state from a state where the first unit is not closed, the inclined part abuts on the engagement projection during the change.
