Abstract:

A modular portable cabana-type restroom includes a roof, base platform, foot portions, side wall panels, a back wall panel, four corner portions and a door. The side wall panels and back wall panel are provided with vertically-disposed hooks for interlocking with complementary slots along the edges of the corner portions. The roof is provided with clips for engaging the corner portions. This permits convenient interlocking removable assembly of the wall panels, corner portions and roof without the use of mechanical fasteners, such as rivets, screws or nuts and bolts. Recesses in the foot portions accept the insertion of the corner portions and corners of the base portion, which are then secured together through formed apertures using a minimum number of mechanical fasteners. This provides for easy assembly and disassembly of the restroom for transport, repair and storage.

Abstract:

A first part of a plastic lid for a garbage container made of metal is secured by a standardized hinge adapter which is installed on one edge of the container. A second part of the plastic lid is slidably adjustable into and out of mating engagement with the first part to form the lid of a selected length. Three different sizes of the second part make the lid fit virtually all known containers. Depending upon the size of the container, two of the two-part slidably adjustable lids may be required to be placed next to each other in order to cover the entire opening in the container. Also, a central bar may be arranged between the two two-part slidably adjustable lids.
