<p>A portable protective structure (10) includes a framework made of corner connectors (16) and various poles (12,20,24), such as vertical supports (12), horizontal supports (20) and roof supports (24). Certain of the support poles (12,20,24) may be made of telescopic tubes (38,40) of circular cross-section joined together by spring locks (42) in the inner tube (38) projecting into arcuate slots (46) in the outer tube (40). Pairs of poles (12,20,24), such as horizontal poles (20), may be connected to a corner connector (16) by the use of a resilient cord (26) extending through the conenctor (16) with a spring clip (30) on each end of the cord (26) inserted into the horizontal pole (20). The roof may include a peak (22) having four sets of extending walls (48) into which each roof pole (24) or eave may be connected with the opposite end of each roof pole (24) inserted into a corner connector (16). <IMAGE></p> |
