Abstract

A safety cabinet has a sturdy box having an open front side and a door hinged to the box and movable between a closed position fitting against the box and closing the front side and an open position pivoted out from the box and exposing the open front side. A shelf can slide in the open position of the door between an in position wholly contained in the box behind the open front side and an out position projecting forward at least partially from the open front side. An arm connected between the door and the shelf moves the shelf into the out position when the door is moved respectively into the open position and into the in position when the door is moved into the closed position.

         7 . The safety cabinet defined in  claim 3  wherein the guide track extends at an acute angle to a direction of travel of the shelf between its in and out positions. 
     
     
         8 . The safety cabinet defined in  claim 3  wherein the track is attached to a downwardly directed bottom face of the drawer. 
     
     
         9 . The safety cabinet defined in  claim 3  wherein the guide track is angled such that on movement of the door between its open and closed out positions the inner end moves through a circularly arcuate path centered on a hinge axis of the door. 
     
     
         10 . The safety cabinet defined in  claim 9  wherein the path extends from a position relative close to a side wall of the box to a position far from the same side wall of the box on movement of the door between the closed and open positions. 
     
     
         11 . The safety cabinet defined in  claim 3 , further comprising:
