A shade canopy (10) structure has several substantially parallel, but laterally spaced rafter members (16, 18, 20), each rafter member (16, 18, 20) having longitudinally extending tracks (30, 32) on its laterally opposite sides. The rafters (16, 18, 20) define a plurality of laterally spaced openings. A plurality of cross beams (22) extend laterally between adjacent rafter members (16, 18, 20) and have their ends engaged in the track (30, 32) for sliding along the track (30, 32). This forms a plurality of laterally spaced tiers of cross beams (22) for each of the laterally spaced openings. A plurality of flexible, laterally spaced opaque sheets (24, 26), each are extendible along one of the laterally spaced openings and each is attached to a tier of cross beams (22) at spaced locations along the sheet (24, 26) so that each sheet (24, 26) may be independently drawn to an extended position and releasably latched in an extended position, or manually withdrawn to a retracted position. |
