Abstract
A portable protective structure includes a framework made of corner connectors and various poles, such as vertical supports, horizontal supports and roof supports. Certain of the support poles may be made of telescopic tubes of circular cross-section joined together by spring locks in the inner tube projecting into arcuate slots in the outer tube. Pairs of poles, such as horizontal poles, may be connected to a corner connector by the use of a resilient cord extending through the connector with a spring clip on each end of the cord inserted into the horizontal pole. The roof may include a peak having four sets of extending walls into which each roof pole or eave may be connected with the opposite end of each roof pole inserted into a corner connector.
