ABSTRACT:
A canopy structure includes a support frame with a plurality of extensible and retractable canopy support sections. Each of the canopy support sections includes a pair of upper transverse support members and two pairs of side support members. Each pair of side support members have lower portions which are pivotally secured to each other and upper portions which are rigidly secured to ends of the upper transverse support members whereby in a retracted position the side support members extend substantially vertical and in an extended position the side support members extend at an acute angle to each other with the upper portions of the side support members spaced apart. The canopy support frame also includes end frames with upper transverse support members secured to the transverse support members of adjacent canopy support sections and generally vertically extending side support members connected to adjacent side support members of adjacent canopy support sections by means for retaining the side support members of the end frames and the adjacent support sections in a fixed, spaced relationship when the canopy structure is extended to maintain the canopy structure in an extended mode. A cover, secured to the canopy support sections and end frames, connects the upper transverse support members of adjacent canopy support sections.
