42 aligned similarly the connectors 34 and 36 on the side 22 will be aligned with the connectors on the side 26 the pole 50 is then placed into the concave region defined by the pairs of aligned connectors 30 38 and 32 40 fig2 illustrates the alignment of connectors 30 and 38 as viewed from the center of the internal space defined by the sections 12 and 14 the pole 50 has two threaded openings 62 and 64 that are adapted to be aligned with the aligned connectors 30 38 and 32 40 respectively one screw 66 can then be inserted from the internal space through the aligned openings 42 for connectors 30 and 38 and 62 and another screw 68 can then be inserted from the internal space through the aligned openings 42 for connectors 32 and 40 and 64 to secure the sides 20 and 24 to the pole 50 the other pole 52 can be secured to the other sides 22 and 26 in the same manner thus the assembly 10 is complete and ready for use when the components of the assembly 10 are disassembled the sections 12 and 14 can be placed one on top of the other in a nested fashion and the poles 50 52 placed in the concave region of the sections 12 14 this provides a slim profile i e two stacked sections 12 14 that will occupy less space for shipping packing storage and transportation although fig1 illustrates the use of two sets of connectors for each side of a section 12 14 it.
