A door arrangement for a wind turbine includes a door with an outer side and an inner side and a door locking device for locking and unlocking the closed door by coupling and decoupling the closed door with a stationary component of the door arrangement of the wind turbine, wherein the door locking device includes a central component, an attachment and a connector, wherein the central component is attached to the stationary component by the attachment and connectable and disconnectable with the door by the connector for locking and unlocking the door by a person being at the outer side, wherein the attachment is manually releasable by a person being at the inner side for disconnecting the central component from the stationary component to unlock the door without tools.

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.

An appliance includes a cabinet that defines an interior chamber. A door is mounted to the cabinet. A lock assembly is configured to selectively secure the door in a closed arrangement. The lock assembly includes a first latch arm rotatably mounted on the cabinet and a second latch arm rotatably mounted on the door. A handle is positioned within the interior chamber of the cabinet. The handle is coupled to one of the first and second latch arms such that the one of the first and second latch arms is rotatable with the handle. A motor is coupled to the other of the first and second latch arms such that the other of the first and second latch arms is rotatable with the motor.

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.

A bin latch system. A bin latch mechanism that has been designed with weight, number of components, simplicity of operation and installation as main design drivers. The bin latch utilizes spring loaded rods that are ‘pulled’ to release the locking subassemblies. The rods lock two sets of interlocking housings in place. Due to the nature of the rod actuator, the design is binary in nature and needs both sets of interlocking housings to be secured before the interface handle can go to ‘full close’ position. Additionally, there is no rigging necessary at install. Once the assembly is in secured in place, it is ready to be operated.

In several embodiments, a person trapped inside a cooler may utilize the cooler safety release device to escape. The person may place his fingers on a pull tab on the inner plate of the safety release device and slide the inner plate away from the outer plate to move the locking tab away from being immediately above the plate of the locking mechanism to being adjacent, but no longer overlapping, with the plate of the locking mechanism. In one or more embodiments, when the locking tab is positioned in a non-overlapping position with the plate of the locking mechanism, the lid is unlocked from the cooler body and is able to be opened, even by someone inside the cooler.

A panic bar latch release assembly is disclosed having an inside latch release and an outside pull type handle latch. The handle latch includes a main housing having a pivotal pull handle. The inside latch release includes a first bar mount, a second bar mount, and an elongated push bar. The first bar mount has a support bracket with a floor with a first stop wall and an extended portion with a push rod guide hole extending therethrough. A body portion is coupled to the support bracket which includes a handle mount channel which is partially defined by a second stop wall. A handle mount is pivotally coupled to the body portion. An elongated push rod is positioned within a push rod channel of the door so as to extend through the push rod guide hole.
