A charging cart includes a casing, at least one door leaf and a hooking mechanism. The casing has at least one first hooking slot. The door leaf is pivotally mounted to the casing so that the door leaf is rotatable relative to the casing about a first rotation axis. The hooking mechanism includes a movable assembly and at least one hooking member. The movable assembly is movably disposed on the door leaf. The hooking member is connected to the movable assembly. The hooking member is driven by the movable assembly to rotate relative to the door leaf about a second rotation axis to be moved between a locked position and an unlocked position. The second rotation axis is parallel to the first rotation axis.

An emergency entry control system which is particularly adaptable for use with double panic doors typically found in schools, movie theaters, and other public facilities. The system includes a base, connecting bracket, and engagement means designed to be removably secured to the top latching mechanism and/or bottom latching mechanism of a conventional double panic door configuration to prevent double panic doors without a center bar from being opened from the outside. The system is rotated manually to permit the panic doors to operate normally. The system can also be modified with wireless and audio technology to effectuate audible and visual notification and facilitate location and communication during emergency situations like an unauthorized attempt at entry or removal of the system.

An astragal is described having a housing and a weather-strip extending along a length of the housing. An end cap is mounted to the housing. The end cap has a bottom wall positioned substantially horizontally along the bottom end of the housing. The bottom wall has an interior edge, an exterior edge opposite the interior edge, an upper surface, and a lower surface opposite the upper surface. At least one projection extends upwardly from the upper surface at a location along the upper surface closer to the interior edge than the exterior edge. The projection sized and positioned to project into the weather-strip and at least partially seal with a cavity opening at a lower end of the weather-strip.

A patch lock assembly releasably secures a glass door to an adjacent glass panel in a locked orientation. The patch lock assembly comprises a latch adapter housing, a strike adapter housing, and first and second power supply adapter housings. The latch adapter housing may interchangeably receive one of any number of various latch mechanisms without requiring further modification of the door. The strike adapter housing may interchangeably receive one of any number of various strikes, including electric strikes, without requiring further modification of the door. Respective power supply adapter housings may be coupled to each latch adapter housing and strike adapter housing. The power supply adapters include a power source and control unit to provide the necessary power to operate the latch and strike. Various interlocking features may be incorporated in the design to resist unwanted movement of the patch lock assembly relative to the glass panel.

A lock mechanism for an inactive door includes a housing configured to receive a locking element from an active door lock. A slide is movably received in the housing and includes a drive bar connection element, wherein when the slide is in an unlocked position, the drive bar connection element is located in a path of travel of the deadbolt, and wherein when the slide is in a locked position, the drive bar connection element is located outside the path of travel of the deadbolt. At least one drive bar at least partially received in the housing and is connected to the drive bar connection element. The drive bar is actuated by an actuator located remote from the housing. A blocking element located within the housing, wherein the blocking element prevents movement of the slide from the locked position to the unlocked position.

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. Locking structures for both single door coolers and double door coolers are disclosed.

A double door assembly bottom restraining device and method provide stability to the double door assembly during manufacturing and shipping. The double door assembly bottom restraining device may be installed on the bottom of a double door assembly.

An automated sash lock for locking a window sash comprises a linearly depressible trigger, a cam-style locking element normally biased towards a locked position, a rotatable detent actuated by the trigger, a pivotable transfer element between the detent and the locking element, and an actuator for manually operating the lock mechanism to unlock the lock when the window is in a closed and locked position. The detent is normally biased in the direction of the locking element and a portion of the detent engages a body portion of the locking element to maintain the locking element in a retracted position when the window is open. Upon actuation of the trigger by a closing window, the trigger translates linearly into the lock housing and rotates the detent into the disengaged position, pulling the detent away from the locking element and allowing the locking element to fire out of the lock housing and into an opening in a strike in the adjacent sash to prevent the sashes from relative sliding movement.
