Abstract: An anti-tilt mechanism is provided for a multi-drawer cabinet. The mechanism has a number of housings each of which has a respective locking cam mounted in it. The locking cams are rotatable about respective cam axes from an inactivated position in which they have a first effective height, to an activated position in which they have a second effective height. The second effective height is greater than the first effective height. The cam is longitudinally moveable within the housing a distance generally corresponding into the difference between the first and second effective heights. Actuating means reacting to movement of the drawers are provided for rotating the cam between the activated and inactivated positions. Respective locking rods extend between adjacent locking cams and are longitudinally moveable with the cams. The anti-tilt mechanism may include a locking mechanism having stop means which limit longitudinal movement of at least one of the cams within its respective housing.
