41 is bent to form an eye bolt shaped loop 42 of such a size so as to snugly surround a rod 22 forming the perimeter of the back 15 in a hinging relation the back 15 is constructed in a manner similar to the base 14 again referring to fig2 the perimeter rod 22 is a rod form metal member bent in rectangular shape to provide longitudinally extending parallel spaced apart legs 22a and 22b which are traversed by a plurality of spaced apart rods 23 disposed across the shorter dimensions the rods 23 are affixed at their ends to the legs 22a and 22b a reinforcing rod 24 traverses the longer dimension of the back 15 intersecting and being joined to each of the rods 23 and connected at opposite ends to legs 22c and 22d the back reinforcing rod 24 is attached to the legs 22c and 22d at approximately the mid point of each respective leg one of the sides and all of the partitions are constructed as shown in fig3 which specifically illustrates the side 16 of the rack but its configuration is identical to that of a partition 18 and like reference numerals will be used to identify like parts a rod 25 forming the perimeter is generally bent into three sides 25a 25b and 25c of a square but the upper front quadrant 25d is curved to form an arc.
