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 door lock for a domestic electrical appliance comprises a movably arranged locking member, which is selectively adjustable into an unlocking position and a locking position and in the unlocking position permits the opening of a closed door of the domestic appliance and in the locking position is in blocking engagement with a blockable component, at least when the door is closed. The blocking engagement causes the closed door to be blocked against opening. The door lock further comprises an electrically controllable actuator for actuating the locking member, and an electrical door detection switch that switches depending on the closing of the door. The doer lock also comprises an electrical auxiliary switch device, which selectively opens or closes an electrical shunt path to the door detection switch depending on the position of the locking member.

A lock unit of an electric locking device comprises a lock housing, a keeper, an inhibitor and a latch bolt. A second end of the latch bolt is positioned outwardly and cooperates with the inhibitor when in a locked orientation. The keeper includes a keeper shaft having a shaft axis of rotation, wherein said keeper is rotatable about said keeper shaft between first and second rotational positions, wherein the keeper is movable between first and second directional positions relative to the lock housing, wherein the movement between the first and second directional positions is generally linear, wherein when the keeper is held in the first rotational position and the first directional position by the inhibitor, the door is secured to the door frame, and wherein when the keeper is in the second rotational position and the second directional position, the door is allowed to move away from said door frame.

An access control device generally includes an electromechanical actuator operable to transition the access control device between a locked state and an unlocked state, an energy storage device operable to store electrical power from a power supply, and control circuitry. The control circuitry is configured to direct a first electrical power from the energy storage device to the electromechanical actuator in response to one or more first criteria. In a fail secure mode, the first electrical power is configured to cause the electromechanical actuator to transition the access control device to the locked state. In a fail safe mode, the first electrical power is configured to cause the electromechanical actuator to transition the access control device to the unlocked state. Certain embodiments further include a user-adjustable switch operable to transition the control circuitry between the fail secure mode and the fail safe mode.

Electromechanical lock utilizing magnetic field forces. An actuator is moved (1202) from a locked position (260) to an open position (400) by electric power. In the locked position (260), a permanent magnet arrangement directs (1204) a near magnetic field to block an access control mechanism to rotate, and simultaneously the permanent magnet arrangement attenuates (1206) the near magnetic field towards a far magnetic break-in field originating from outside of the electromechanical lock. In the open position (400), the permanent magnet arrangement directs (1208) a reversed near magnetic field to release the access control mechanism to rotate, and simultaneously the permanent magnet arrangement attenuates (1210) the reversed near magnetic field towards the far magnetic break-in field.

An electromechanical lock cylinder. The cylinder includes a core front end, a core back end coupled with a tailpiece, an actuator mechanism, switchable between a locked state and an unlocked state, to keep the core front end uncoupled with the core back end in the locked state, to couple the core front end with the core back end in the unlocked state to enable the core front end to rotate the core back end from a locked rear position to an unlocked rear position, and to return to keep the core front end uncoupled with the core back end in the locked state; an enforced coupling to couple the core front end with the core back end as the core front end starts to rotate the core back end away from the locked rear position in the unlocked state, and decouple the core front end from the core back end as the core back end returns to the locked rear position; an operation knob, coupled with the core front end, to enable a user to rotate the operation knob from an initial knob position so that the core front end rotates the core back end from the locked rear position to the unlocked rear position in the unlocked state; and a return force mechanism to rotate the operation knob further after the user first has rotated the operation knob away from the initial knob position and then released the operation knob, whereby the core back end is rotated to the locked rear position by the core front end due to the coupled enforced coupling.

The invention relates to a locking device for doors, compartments, and flaps. The stator is equipped with a battery-operated motor and an electronic control unit which acts on the motor. A handle (20) is connected to the rotor (30) so as to transmit a torque and is held on the rotor (30) by a clamping spring (50). The clamping spring (50) has a receiving area for a magnet (60). The process of replacing the battery for the motor is easily facilitated in that the clamping connection between the handle (20) and the rotor (30) is triggered by an external influence on the magnet (60) (FIG. 1).

A clutch includes an outer box and an intermediate member pivotably connected to the outer box. The intermediate member is coupled with an outer handle to pivot therewith. A torsion spring is disposed between the intermediate member and the outer box and biases the intermediate member to an initial position. A coupling member is pivotably mounted between the intermediate member and the outer box and is operatively connected to a first latch of a latch device of a lock device. When the coupling member and the intermediate member are jointly pivotable, pivotal movement of the outer handle causes the first latch to move from the latching position or the unlatching position. When the coupling member is not jointly pivotable with the intermediate member, pivotal movement of the outer handle is incapable of causing movement of the first latch. A lock device with the clutch is also disclosed.
