Bolster for a safety cabinet

Abstract

A cabinet including a receptacle having a floor, a front wall, a rear wall, and a pair of opposed sidewalls extending upwardly from the floor. A plurality of bolsters is attached to the floor, each bolster including a lower panel defining at least a first aperture having a longitudinal center axis, and a first and a second sidewall, each extending from the lower panel toward the floor, the first sidewall defining an acute angle with the lower panel and defining a first aperture disposed vertically above a corresponding first aperture of the lower panel. A leg is rotatably received within the first aperture so that rotation of the leg results in the leg moving axially with respect to the lower panel.

What is claimed is: 
     
         1 . A cabinet, comprising:
 a receptacle having a floor, a front wall extending upwardly from the floor, a rear wall extending upwardly from the floor, and a pair of opposed sidewalls extending upwardly from the floor, wherein the floor includes a front edge, a rear edge and a pair of side edges defining a perimeter of an underside surface of the floor, wherein the front edge and the rear edge are parallel to each other, and wherein the side edges are parallel to each other;   a plurality of bolsters attached to the underside surface of the floor, each bolster comprising:   a lower panel spaced apart from the underside surface of the floor, the lower panel defining at least a first aperture having a longitudinal center axis;   a first and a second sidewall, each sidewall extending from the lower panel toward the floor so that an inner surface of each first and second sidewall defines an acute angle with a topside surface of the lower panel, one of the first and second sidewalls defining at least a first aperture disposed vertically above the first aperture of the lower panel; and   a leg that is rotatably received within the first aperture of the lower panel so that rotation of the leg with respect to the lower panel results in the leg moving axially with respect to the longitudinal center axis of the first aperture of the lower panel.   
     
     
         2 . The cabinet of  claim 1 , wherein the first aperture of the lower panel further comprises a threaded bore and the leg further comprises a correspondingly threaded stem. 
     
     
         3 . The cabinet of  claim 2 , wherein the leg further comprises a foot, the foot being rotatable with respect to the threaded stem of the leg. 
     
     
         4 . The cabinet of  claim 2 , wherein the leg further comprises a head portion, the head portion having a polygonal cross-section taken perpendicular to a longitudinal center axis of the leg. 
     
     
         5 . The cabinet of  claim 2 , wherein the leg further comprises a head portion defining a recess in its top surface so that the leg is rotatable by a tool having a projection that is correspondingly-shaped to the recess. 
     
     
         6 . The cabinet of  claim 1 , wherein the longitudinal center axis of the first aperture of the lower panel passes through the first aperture defined by the one of the first and second sidewalls. 
     
     
         7 . The cabinet of  claim 1 , wherein the first aperture of the one of the first and second sidewalls is defined by the first sidewall, and wherein the first sidewall extends horizontally outwardly beyond the perimeter of the underside surface of the floor. 
     
     
         8 . The cabinet of  claim 1 , wherein the leg further comprises a first end disposed within the bolster and a second end extending outwardly from the lower panel of the bolster, and rotation of the leg is a clockwise direction, viewed from above through the first aperture of the one of the first and second sidewalls, moves the second portion of the leg outwardly from the lower panel. 
     
     
         9 . The cabinet of  claim 1 , wherein the first wall of the cabinet defines at least one opening so that an interior of the receptacle is accessible through the opening. 
     
     
         10 . The cabinet of  claim 9 , further comprising a door that is pivotably connected to the receptacle so that the door is selectively positionable over the at least one opening. 
     
     
         11 . The cabinet of  claim 1 , wherein each sidewall extends from the lower panel toward the floor in a direction parallel to the front edge and the rear edge of the perimeter of the floor. 
     
     
         12 . A cabinet, comprising:
 a receptacle having a floor, a front wall extending upwardly from the floor, a rear wall extending upwardly from the floor, and a pair of opposed sidewalls extending upwardly from the floor, wherein the floor includes a front edge, a rear edge and a pair of side edges defining a perimeter of an underside surface of the floor;   a plurality of bolsters attached to the underside surface of the floor, each bolster comprising:   a lower panel spaced apart from the underside surface of the floor, the lower panel defining at least a first aperture having a longitudinal center axis;   a first and a second sidewall, each sidewall extending from the lower panel toward the floor, the first sidewall defining an acute angle with a topside surface of the lower panel and defining a first aperture disposed vertically above the first aperture of the lower panel; and   a leg that is rotatably received within the first aperture of the lower panel so that rotation of the leg with respect to the lower panel results in the leg moving axially with respect to the longitudinal center axis of the first aperture of the lower panel.   
     
     
         13 . The cabinet of  claim 12 , wherein the first aperture of the lower panel further comprises a threaded bore and the leg further comprises a correspondingly threaded stem. 
     
     
         14 . The cabinet of  claim 13 , wherein the leg further comprises a foot, the foot being rotatable with respect to the threaded stem of the leg. 
     
     
         15 . The cabinet of  claim 13 , wherein the leg further comprises a head portion, the head portion having a polygonal cross-section taken perpendicular to a longitudinal center axis of the leg. 
     
     
         16 . The cabinet of  claim 13 , wherein the leg further comprises a head portion defining a recess in its top surface so that the leg is rotatable by a tool having a projection that is correspondingly-shaped to the recess. 
     
     
         17 . The cabinet of  claim 12 , wherein the longitudinal center axis of the first aperture of the lower panel passes through the first aperture defined by the one of the first and second sidewalls. 
     
     
         18 . The cabinet of  claim 12 , wherein the first sidewall extends horizontally outwardly beyond the perimeter of the underside surface of the floor. 
     
     
         19 . The cabinet of  claim 12 , wherein the leg further comprises a first end disposed within the bolster and a second end extending outwardly from the lower panel of the bolster, and rotation of the leg is a clockwise direction, viewed from above through the first aperture of the first sidewall, moves the second end of the leg outwardly from the lower panel.
