Stackable and combinable rack

Abstract

A stackable and combinable rack is composed of a plurality of U-shaped struts. Each of the struts includes two U-shaped bars spaced from each other, and two connecting bars connected between two respective adjacent ends of the U-shaped bars. Each of the two U-shaped bars has a bottom section and two lateral sections extending from two ends of the bottom section respectively. The U-shaped struts are arranged in at least two pairs. In each pair of the struts, the bottom bars of one strut are adjacent to those of the other strut. The at least two pairs of the struts are vertically arranged. The bottom bars of one pair of the struts cross those of the other pair of the struts. One pair of the struts is located outside the other pair of the struts. In light of this, a plurality of receiving spaces are formed.

1 . A rack comprising:
 a plurality of U-shaped struts, each of which has two connecting bars and two U-shaped bars spaced from each other, each of said U-shaped bars having a bottom section and two lateral sections extending from two ends of said bottom section, each of said connecting bars being connected between two respective adjacent ends of said two U-shaped bars, said U-shaped struts being arranged in at least two pairs, said bottom sections of one U-shaped strut being adjacent to those of the other strut in each pair of said U-shaped struts;   wherein first and second pairs of said U-shaped struts are vertically arranged, and said bottom sections of one pair of said struts are crossed with and arranged outside those of the other pair of said struts, whereby a plurality of receiving spaces are formed.   
   
   
       2 . The rack as defined in  claim 1 , wherein said bottom sections of said first pair of said struts are horizontally located. 
   
   
       3 . The rack as defined in  claim 2 , wherein said bottom sections of said first pair of said struts are located outside those of the second pair of said struts. 
   
   
       4 . The rack as defined in  claim 2 , wherein said bottom sections of said second pair of said struts are located outside those of the first pair of said struts. 
   
   
       5 . The rack as defined in  claim 1 , wherein each of said receiving spaces is formed and defined by said lateral section and a part of said bottom section of one of said U-shaped bars and those of another U-shaped bar. 
   
   
       6 . The rack as defined in  claim 1 , wherein each of said U-shaped struts further comprises two respective hook-shaped portions, each of which is formed of said connecting bar and said two lateral sections bending toward each other for a predetermined length.
