ABSTRACT:
An interlock system for a multi-draw cabinet having a latching module for each drawer which is actuated by the movement of the draw between an open and a closed position relative to the cabinet. Each latching module includes a base which is mounted to the side wall of the cabinet and includes an actuating lever which is pivotally mounted on the supporting base and is moved between a non-actuating position and an actuating position through an inter-connection between the lever and the drawer. An elongated transmitter extends between each adjacent latching module for relative longitudinal movement between adjacent latching modules within appropriate vertical passageways in the modules. Each latching module has a horizontal passageway which intersects the vertical passageway and which contains a horizontally-extending transmitter which is moved toward the vertical passageway by movement of the actuating lever from its non-actuating position to its actuating position upon opening of its corresponding drawer. The movement of the horizontal transmitter engages the end of the corresponding vertical transmitter and displaces it along its vertical longitudinal axis so that the opposite end of the vertical transmitter is misaligned with the horizontal transmitter of the adjacent latching module and prevents the actuating lever of the adjacent latching module from moving to its actuating position and thereby preventing its corresponding drawer from opening.
