Abstract
A locking system, for a cabinet having a plurality of drawers extendably mounted in an interior of the cabinet, includes a bar and a motor unit. The bar is movable to prevent at least some of the drawers from extending out of the cabinet when in a locked position and allowing at least one of the drawers to extend out of the cabinet in an unlocked position. The motor unit is configured to drive an arm coupled to the bar, the arm being drivable to change a position of the bar from the locked position to the unlocked position.

A locking system for a cabinet including a plurality of drawers extendably mounted in an interior of the cabinet, the locking system comprising:
- a bar movable to prevent at least some of the drawers from extending out of the cabinet when in a locked position and allowing at least one of the drawers to extend out of the cabinet in an unlocked position;
- and
- a platform connected to and extending from the bar;
- a motor unit having a casing having at least a portion sized to fit within a width of a space between a drawer and a cabinet sidewall, with a motor within the casing to drive, within the casing, a cam arm extending from an opening in the casing, the cam arm drivable to contact and lift the platform to change a position of the bar from the locked position to the unlocked position;
- wherein a first sensor is positioned in the casing of the motor unit to detect when the cam arm is in a first predefined position, and a second sensor is positioned in the casing of the motor unit to detect when the cam arm is in a second predefined position, and the first sensor and the second sensor are electrically coupled to control circuitry for operating the motor driving the cam arm;
- wherein a first cam stop extends radially from the cam arm and is configured to trip the first sensor, and a second cam stop extends radially from the cam arm and is configured to trip the second sensor, and
- wherein the casing includes a pair of apertures for mounting the casing to a cabinet side panel.
A locking system for a housing, the housing containing a plurality of inner slide members slidably coupled to the housing, the locking system including:
- a restricting element movable to prevent at least more than one of the inner slide members from sliding at least partially out of the housing when in a locked position and allowing at least one of the slides to slide out of the housing in an unlocked position;
- and
- an electrically powered driving unit coupled to the restricting element, and drivable to shift a position of the restricting element from the locked position to the unlocked position, the electrically powered driving unit including a casing having at least a portion sized to fit within a width of a space between a drawer and a cabinet sidewall, a motor with an extending spindle and a cam, the cam drivable within the casing by the motor by way of the spindle, with the cam positionable to urge against the restricting element to move the restricting element out from the locked position.
