Abstract:
1. A safety cabinet comprising: a body having an open front side; first and second doors hinged to the body and pivotal thereon about respective parallel first and second axes between closed positions fitting against the body and closing the front side and open positions pivoted out from the body and exposing the open front side; a shelf slidable in a direction between an in position wholly contained in the body behind the open front side and an out position projecting forward at least partially from the open front side; a guide rail fixed underneath the shelf and extending at an acute angle to the direction; an arm fixed to and defining a predetermined fixed angle from the first door and having an inner end provided underneath the shelf with a follower pin riding in the guide rail such that pivoting the first door about the first axis into the respective open position pulls the shelf into the out position and pivoting the first door about the first axis into the respective closed position pushes the shelf into the in position while moving the follower pin on a circular arc centered on the first axis, the follower pin being spaced in the closed position of the first door farther from a front side of the shelf than in the open position of the first door; and a rigid link pivoted on the second door and on the inner end of the arm for movement of both of the doors into the respective open positions on movement of either of the doors into the respective open position and for pulling both of the doors into the respective closed positions on movement of the either of the doors into the respective closed position with movement of the shelf from the out position to the in position on movement of either of the doors to the closed position and travel of the pin along the arc.
