A collapsible shade structure includes a plurality of foldable frame
members each having a folded and an unfolded orientation. A fabric
material is provided for substantially covering the frame members to form
a side panel for each frame member, each side panel assuming the unfolded
orientation of its associated frame member. Interconnecting portions of
the fabric material form a hinge portion between each frame member.
Alternatively, frame retaining sleeve portions may be used to
interconnect and retain two or more frame members from two or more
adjacent side panels and to act as hinge portions. The structure may be
folded and stored by folding the side panels and their corresponding
frame members on top of each other about the hinge portions to have the
side panels and frame members overlying each other. The overlaying side
panels and frame members are then collapsed by twisting and folding to
form a plurality of concentric frame members and side panels to
substantially reduce the size of the shade structure.
