Box holder

Abstract

A box holder comprises: a pair of T-frames arranged parallel to face opposite directions, each T-frame having a crossbar and a stem, each edge of the T-frame being bent downward to form a vertical bracket; U-shaped extensions formed at open edges of the T-frame, each end of the U-shaped extensions being connected to the vertical bracket; and reinforcement elements formed along the crossbars of the T-frames.

1 . A box holder comprising:
 a pair of T-frames arranged parallel to face opposite directions, each T-frame having a crossbar and a stem, each edge of the T-frame being bent downward to form a vertical bracket;   U-shaped extensions formed at open edges of the T-frames, each end of the U-shaped extensions being connected to the vertical bracket; and   reinforcement elements formed along the crossbars of the T-frames.   
     
     
         2 . The box holder of  claim 1 ,
 wherein the reinforcement elements extend from the crossbars to the U-shaped extensions.   
     
     
         3 . The box holder of  claim 2 ,
 wherein the reinforcement elements form a continuous loop of ribs extending from the crossbars to the U-shaped extensions.   
     
     
         4 . The box holder of  claim 2 ,
 wherein the reinforcement elements are solid plates.   
     
     
         5 . The box holder of  claim 2 ,
 wherein the reinforcement elements are hollow plates.   
     
     
         6 . The box holder of  claim 2 ,
 wherein the reinforcement elements are T-shaped solid plates.   
     
     
         7 . The box holder of  claim 2 ,
 wherein the reinforcement elements are T-shaped hollow plates.   
     
     
         8 . The box holder of  claim 2 ,
 wherein the T-frames and the U-shaped extensions are integrally formed with the reinforcement elements.   
     
     
         9 . The box holder of  claim 1 ,
 wherein a first angle at a first edge between T-frame and the vertical bracket is a right angle.   
     
     
         10 . The box holder of  claim 9 ,
 wherein a second angle at a second edge between the vertical bracket and the U-shaped extension is an obtuse angle, creating a space between the inner surface of the U-shaped extension and the outer surface of a box.   
     
     
         11 . The box holder of  claim 10 ,
 wherein a third angle at a third edge between the U-shaped extension and a handle formed at the end of the U-shaped extension is an obtuse angle, where the third angle is smaller than the second angle and larger than the first angle.   
     
     
         12 . The box holder of  claim 1 ,
 wherein the reinforcement elements are ribs formed upright along the crossbars of the T-frames.   
     
     
         13 . The box holder of  claim 1 ,
 wherein the T-frame employs a hollow box beam structure formed by the integration of the reinforcement elements along the crossbar of the T-frame.   
     
     
         14 . The box holder of  claim 1 ,
 wherein the reinforcement elements are double sided rib reinforced plates, and the reinforcement elements are further formed along the vertical brackets and the U-shaped extensions.
