A cooler access control system locks a cooler when occurrence of an event is detected that requires limiting access to the inside of the cooler. Examples of such events include the loss of power to the cooler for a predetermined period of time, the opening of the cooler door for longer than an allowed time, the loss of functionality of a temperature probe and others. In an embodiment, a service mode is supported wherein the door is left unlocked despite the occurrence of such an event, to allow a stocker or other personnel to leave the cooler door open while stocking the cooler with product.

A dispensing cabinet may include a security panel and a plunger having a disengaged position and an engaged position. The plunger may be secured in the disengaged position by the security panel. The security panel may be released in order to transition the plunger from the disengaged position to the engaged position. The dispensing cabinet may further include a lever configured to interface with the plunger and one or more latch assemblies. The lever may shift upwards in response to the plunger being transitioned from the disengaged position to the engaged position. An upward motion of the lever may release the one or more latch assemblies by rotating, to a limit, a cam bracket included in each of the one or more latch assemblies. The dispensing cabinet may be unlocked by the release of the one or more latch assemblies.

A safe for the storage of a valuable, such as a firearm. The safe has an imaging system that is used to scan a portion of a human in the near infrared spectrum to image blood vessels and determine if the image matches a stored image and thereafter effect unlocking of the safe. A manual override lock system is provided to manually effect unlocking of the safe.

An electronic device and method are disclosed. The electronic device includes a housing defining an opening, a driving actuator, a slide door moveable to selectively cover and expose the opening, a link connecting the slide door and the driving actuator, the link linearly moveable in accordance with a driving operation of the driving actuator to move the slide door, a forcible open blocker that is moveable to restrict opening of the slide door when the opening is closed, and to release blockage of the opening of the slide door based on a linear movement of the link, and a processor. The processor implements the method, including: receiving an external input signal and identify whether to expose or cover the opening based on the external input signal, and activating the driving actuator to expose or cover the opening according to a result of the identification.

A system is disclosed for converting an overhead door into a gate or serving window, the system having at least two rows of panels spanning the width of the door, one panel located above and adjacent to the other panel, a pair of rails opposite one another and adjacent to the panels, the panels traveling within the rails to move from a closed position to an open position, and at least one hinge connecting the lower row of panels to the upper row of panels, the hinge having an upper half attached to the upper row of panels and a lower half attached to the lower row of panels, the upper and lower halves of the hinge connected by a removable central pin, wherein the upper row of panels moves from the closed position to the open position when the central pin is removed from the hinge.

A tugger train trailer (1) with a chassis (2) and a transport device (7) is disclosed and configured to hold at least one cargo carrier (LT) having rollers (R), wherein the tugger train trailer (1) is provided with at least one locking means (20) that secure the received cargo carrier (LT) in the transverse direction (Q) of the vehicle of the tugger train trailer (1). The locking means (20) has a locking element (21a; 21b) that can be electro-mechanically actuated between a locked position and an unlocked position, wherein the locking element (21a; 21b) is actuated by a spring device (30) toward the locked position and by means of an electric drive device into the unlocked position.

A storage lock for a storage door, the lock comprising a lock housing for mounting to the storage door or a storage frame supporting the door; and a lock mechanism arranged within the lock housing, the lock mechanism comprising a latch selectively operable between a locked position in which the latch is extended to engage with the other of the storage door and storage frame to block against opening of the storage door, and an unlocked position in which the latch is retracted to disengage from the other of the storage door and storage frame to allow the storage door to be opened for access to storage, and a latch control system selectively operable between a restricted position to block against operation of the latch out from the locked position, and an unrestricted position to permit operation of the latch out from the locked position to the unlocked position.

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.

In one aspect of the present disclosure, a locking device is provided including an interchangeable core (IC), a barrel, an anti-rotation plate, a prong driver, a bolt and a backplate. The barrel is coupled to the backplate and includes a hollow interior to receive the IC. The bolt is slidably disposed in a slot of the backplate. The IC includes a key hole. The prong driver is coupled to the IC and the bolt, such that, when a proper key is inserted into the key hole and rotated the bolt can be extended from the slot in a direction away from the locking device or retracted into the slot in a direction toward the interior of the locking device. The anti-rotation plate of the locking device is coupled to the barrel to prevent the locking device from being rotated relative to a structure the locking device is mounted to.
