A trailer locking assembly for locking a door of a trailer includes a lock rod pivoting about its axis of elongation within an upper and a lower bracket. A top and bottom cam attach to the top and bottom of the lock rod, respectively, and the top and bottom cams are configured to engage with corresponding keepers. A handle attached to the bottom cam beneath the door is configured to engage with a first latch assembly. The latch assembly may be configured to be released from an interior of the trailer. The first latch assembly may be attached to the lower bracket. The locking assembly may have a second latch assembly for holding the door open.

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.

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).

The present invention relates to a catcher release device for a refrigerator and freezer, and more particularly, to a catcher release device for a refrigerator and freezer that has releasing means disposed on the inside of a side panel on which a catcher is located in such a manner as to be connected to the catcher, so that if a person is locked in the refrigerator and freezer, an inner handle of the releasing means just rotates, irrespective of a door lock device, thus allowing the catcher to be separated from the door lock device to rapidly open a door for the refrigerator and freezer.

A watertight door or window comprising a frame and a leaf mounted on the frame and arranged movably with respect thereto between an open position and closed position, and further comprising: a striker element arranged on the leaf, a locking element arranged on the frame and provided with a hook end designed to engage with the striker element so as to lock the leaf against the frame following closing of the leaf, and a striker actuating mechanism arranged on the leaf and able to be actuated when the leaf is in a closed position and the locking element is engaged with the striker element. The actuating mechanism is provided for releasing the striker element from a closed position, where the striker element is positioned inside a recess in the hook end of the locking element, to an open position, where the striker element is extracted from the recess in the hook end of the locking element. The actuating mechanism can be reset when the leaf is closed again.

An emergency shelter includes a number of reinforced walls that define a substantially enclosed interior space in which people can enter in emergencies; a doorway opening formed in at least one of the walls to permit entry into and exit from the interior space; a door mounted over that doorway opening; and a latching assembly for latching and locking the door in its closed position. The door is configured to slide horizontally relative to the doorway opening between an open position and a closed position so that it can be opened even when debris is blown up against it. The shelter also includes a door jamb adjacent the doorway opening for receiving and partially surrounding a leading edge of the door to prevent movement of the door along an axis transverse to the horizontal sliding direction of the door so that the door does not cave in when struck by debris. A flange on the trailing edge of the door overlaps a flange on the front wall when the door is closed to prevent movement of the door along an axis transverse to the horizontal sliding direction of the door so that the trailing edge of the door does not cave in when struck by debris. The latching assembly securely latches and locks the door in its closed position but permits the door to be opened even when portions of the latching assembly are damaged.
