Abstract: A hinge for a swinging gate includes a base plate, a hinge base pivotally secured to the base plate and a mounting member connected in spaced apart relation to the hinge base by an elongate bolt. A gate-engaging member is secured to the mounting member so that pivoting of the hinge base effects conjoint pivoting of the mounting member, the gate-engaging member and a gate that it engages. An upstanding post has a pair of laterally spaced apart T-shaped slots that extend along its height. A bolt disposed within a T-shaped slot is disposed horizontally and cannot rotate. The bolts housed in a T-shaped slot screw-threadedly engage apertures formed in the corners of the base plate to secure the base plate to the upstanding post. In a second embodiment, a cantilever gate supported by a trolley assembly is secured in cantilever relation to at least one upstanding post.

Abstract: A roof structure for enclosures for swimming pools, spas, or patios and the like includes a plurality of laterally spaced angled roof beams each having a plurality of vertically spaced tracks on facing sides of adjacent beams for sliding receipt of one roof panel in each opposed set of tracks. The trailing ends of each higher panel is releasably latched to the leading end of each succeeding lower panel within their respective tracks, whereby the succeeding lower panels can be successively used to push or pull the preceding higher panels by hand along their respective tracks during assembly and removal of the panels from the roof structure.
