Abstract: A three-dimensional figure made from an inflatable, sculptured envelope of soft pliable material into which is blown a constant flow of ambient air wherein said flow of ambient air can be modulated or reversed to cause a lifelike movement of the sculptured figure. The inflatable envelope can be attached to the face of a billboard to create a three-dimensional display which can be quickly assembled or dismantled. The structure can tolerate substantial leakage of air from the envelope along seam lines, through the pliable material fabric or small puncture holes.

Abstract: A game set for simultaneously playing at least two interactional games on a single chessboard which comprises two or more subsets of pieces wherein each piece in each subset has a different size than the corresponding piece in the other subsets and is fractionally shaped in order to combine with at least one other piece from any other subset on a single square of the chessboard. The game in which a particular piece is currently operating is indicated by a color-coded ring insertable over a stub projecting from the top of said piece. The base of each piece is tierce-shaped with at least two adjacent sides defining vertical planes intersecting each other at 120.degree. whereby at least two bases can be contiguously placed in a circular pattern on a single square of the chessboard.

Abstract: A trash container lid system for placement on top of large industrial trash bins of the type utilizer in hotels, apartment houses, etc., in which a lid section is rotatably coupled to a trash bin. The lid in one embodiment is slidably coupled to the top surfaces of the side sections of the trash bin via rollers on the lid and a roller track on the top edge of the side sections and rotatably coupled to the trash bin via a lever arm rotatably coupled at one end to the trash bin and to another end to a back lower portion of the lid section.

Abstract: A trash bin lid for covering a rectangular top edge of a trash bin in which front and back sections are provided, each of said front and back sections having a raised back portion thereof with the front section having a roller captured within a track on the top of the back section and a roller in the front portion of the front section riding on the trash bin ledge whereby the front section of the trash bin lid can be pushed toward the rear, allowing the back roller to ride up the back section of the trash bin lid, at which time trash can be dropped into the trash bin and the front section of the trash bin released, allowing it to gravity close. The back lid section is hingedly attached to the back edge of the bin so that when dumping, i.e., inverting the bin, both lid sections extend downwardly from the top edge of the bin.
