Cabinet with a roll door

Abstract

A cabinet includes two opposite sidewalls and a roll door apparatus. Each sidewall longitudinally defines a number of cutouts. The roll door apparatus includes a first pole rotatably mounted between tops of the sidewalls, a roll door reeled about the first pole. The roll door has a first end mounted to the pole, and a second end opposite to the first end. A fixing piece extends from the second end of the roll door. Opposite ends of the fixing piece are engaged in two of the cutouts of the sidewalls.

         6 . The cabinet of  claim 5 , wherein the roll door further comprises a third connection piece comprising two latches and an engaging portion forming a third hook at a top end of the engaging portion, the engaging piece extends from a bottom end of the engaging portion opposite the third hook, and the latches of the third connection piece are movably latched with the second bottom hook of the operation portion opposite to the main pieces and the third hook. 
     
     
         7 . The cabinet of  claim 1 , further comprising a second pole pivotably connected between tops of rear sides of the sidewalls, wherein the roll door rounds the second pole from bottom to top and passes a top of the first pole. 
     
     
         8 . The cabinet of  claim 1 , wherein the roll door further comprises a resilient belt fixed between the first end of the roll door and the first pole. 
     
     
         9 . The cabinet of  claim 8 , further comprising at least one clockwork spring fitted about the first pole and connected between the first pole and one of the sidewalls. 
     
     
         10 . The cabinet of  claim 1 , further comprising at least a clockwork spring fitted about the first pole and connected between the first pole and one of the sidewalls. 
     
     
         11 . The cabinet of  claim 10 , wherein the clockwork spring comprises an inner end mounted to the first pole and an outer end mounted to an inner surface of one of the sidewalls. 
     
     
         12 . The cabinet of  claim 1 , wherein the roll door defines a plurality of vents. 
     
     
         13 . The cabinet of  claim 1 , wherein each cutout of the sidewalls has a cuneiform cross-section. 
     
     
         14 . A cabinet, comprising:
 two opposite sidewalls each longitudinally defining a plurality of cutouts in a front side;   a first pole pivotably mounted between tops of front sides of the sidewalls;   a second pole pivotably mounted between tops of rear sides of the sidewalls;   a resilient belt comprising a firs end fixed to the first pole; and   a roll door connected to a second end of the resilient belt opposite to the first end of the resilient belt; wherein the resilient belt and the roll door are reeled about the first pole, the roll door rounds the second pole from bottom to top and passes a top of the first pole; an engaging piece extends from a distal end of the roll door opposite to the resilient belt, opposite ends of the engaging pieces detachably engage in two cutouts of the sidewalls.   
     
     
         15 . The cabinet of  claim 14 , further comprising at least one clockwork spring fitted about the first pole. 
     
     
         16 . The cabinet of  claim 15 , wherein the at least one clockwork spring comprises an inner end mounted to the first pole and an outer end mounted to an inner surface of one of the sidewalls. 
     
     
         17 . The cabinet of  claim 14 , wherein the roll door comprises a plurality of main pieces each comprising a top hook and a bottom hook, and a plurality of connection pieces each comprising two latches; every two adjacent main pieces are movably connected to each other by one of the connection pieces, the latches of each connection piece are movably latched with the top hook of one of the main pieces and the bottom hook of another one of the main pieces.
