发明名称 Canopy structure
摘要 The canopy structure of the present invention includes a generally rigid internal frame structure comprised of light-weight metal tubes and a pliable, waterproof covering such as nylon or other functionally similar fabric. The canopy covering further includes a series of grommet reinforced securing points which are each adapted to receive a tie-down or securing cord. These securing cords are formed of a loop of elastic or shock cord material which is attached to a ball-shaped stopper. Threaded into the edges of the canopy end panels are a pair of elastic bolt cords which also incorporate ball-shaped stoppers at both ends. The canopy covering is stretched taughtly across the top of the frame structure and attached to individual horizontal frame members using the elastic securing cords. Grommets located along the sides of the covering are attached to individual vertical frame members using both the elastic securing cords and an associated securing or locking tab. The elastic bolt cords associated with the ends of the covering are also attached to individual vertical frame members using the locking tabs.
