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 latch module for controlling an opening and a closing of a door of an appliance includes a latch, a spring that applies an elastic force to the latch, a motor; and a cam that contacts a contact surface of the latch and is coupled to the motor to drive the cam to pivot the latch. The cam includes a first radius, a second radius, and a third radius in a circumferential direction at an outer circumference of the cam. The latch is positioned at a first basic position when the first radius of the cam contacts the contact surface of the latch, positioned at a second basic position when the second radius of the cam contacts the contact surface of the latch, and positioned at a third basic position when the third radius of the cam contacts the contact surface of the latch.

A locking module for selectively coupling a first component and a second component of a lockable device includes a locking element including a plurality of locking fingers movable between an open position and a closed position. The plurality of locking fingers being biased to said open position. A biasing mechanism is coupled to said locking element and a compression force applied by said biasing mechanism to said plurality of locking fingers controls movement of said plurality of locking fingers between said open position and said closed position. An actuator associated with said biasing mechanism is operable to control said compression force to selectively lock said locking element.

An electrically actuated locking mechanism may include a microprocessor for control of the locking mechanism, and the locking mechanism may be used to lock a drawer slide in a closed position. The microprocessor may be in a housing of the locking mechanism, and the microprocessor may command a motor to operate in a first direction to drive lock components to a locked status and command the motor to operate in a second direction to drive the lock components to an unlocked state.

An electronic latch assembly includes a latch bolt movable between an extended position and a retracted position; and a motor having a rotatable output shaft arrangement that is either directly or indirectly connected to the latch bolt for moving the latch bolt between the extended and retracted positions and rotating the output shaft arrangement between a first angular position in which the latch bolt is capable of being translated to the retracted position and a second angular position in which the latch bolt is locked and not capable of being translated to the retracted position.

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.

The invention relates to a child safety locking mechanism 1 for a cupboard or drawer 2 comprising at least one movable door or drawer 3 and a fixed frame 2, and the locking mechanism 1 comprising: a latch assembly 5 and a catch part 4 each fitted on the movable door or drawer 3 and fixed frame, the latch assembly 5 including a latching arm 8 and a latching hook 9, and the catch part including a catch arm 6. The latching hook 9 is aligned to abut against the catch arm 6 in a locked position to prevent the movable door from being fully opened, wherein the latching arm is movable to an unlocked position in which the latching hook 9 is no longer aligned to abut against the catch arm 6 and the movable door or drawer 3 may be opened. Motor driven automatic release means are provided which are remotely actuatable to automatically move the latching arm 8 to the unlocked position when the automatic release means are actuated by a user. The latching arm 8 is moved downwards automatically by the remote actuation of the release arm 20 out of alignment with the catch arm 6. The release arm 20 is mounted on an axle which is rotated by a motor to just a sufficient extent to act on the latch arm 8 to move it out of alignment with the catch arm 6. The latch assembly 5 includes control means for the motor in the form of a circuit board, which also includes a Bluetooth or other radio wave receiver, located in a latch assembly casing 22.

A rim strike assembly includes a strike body, strike jaw, retaining clutch, locking cam, locking clutch, and a solenoid. The strike jaw, retaining clutch, locking cam, and locking clutch are pivotably coupled to the strike body. The strike body and strike jaw define a latch cavity to receive a latch of a door. The strike jaw includes a jaw follower. The strike jaw is pivotable between a release position and a closed position. The retaining clutch engages the jaw follower and includes a retaining follower. The locking cam includes a retaining notch and a locking notch. The retaining follower engages the retaining notch. The locking clutch includes a locking follower that engages the locking notch of the locking cam. The solenoid includes a plunger coupled to the locking clutch such that movement of the plunger rotates the locking clutch from a locked position to an unlocked position.
