Abstract: A shelter has two hinge assemblies on opposite sides and a series of hoops radiating from the hinge assemblies to support a canopy. The shelter may be opened from either end. Each hinge assembly includes two arms that support respective halves of the support hoops. The arms pivot about a lateral pivot axis so that when the shelter is opened, one of the arms will pivot upwardly so that the hoops carried by it will lie flat on top of the hoops attached to the other hinge arm.

Abstract: A multipurpose aquatic float has a molded shell of plastic resin. The float has a generally rectangular base part with a set of integral mounting flanges on its top surface. The mounting flanges are arranged to provide a longitudinal center channel for accepting a framing member of standard dimension lumber. Transverse flanges support the longitudinal flanges and provide a cross channel at the center and end notches to accommodate cross bracing in the frame on which the float is mounted. The longitudinal flanges have molded-in fastener receivers for receiving fasteners that secure the float in place on the framework of the support structure.
