Abstract: A portable water-containing structure formed from a series of interlocking panel elements that can be interlocked easily without the use of tools. These panels may be used to form such water-containing structures as wading or swimming pools and may also be used to form an ice rink, spa, fish pond, flowerbox, window box and may other elements. The structures so formed are easy to assemble and disassemble, are strong and utile and can be formed in situ at any desired location.

Abstract: A portable containing structure comprising a series of interlocking panels that, when constricted form the containing structure. These panels may be used to form such structures as a pool (swimming or wading) and may also be used to form an ice rink, spa, sandbox, window box, etc. The structures so formed are strong and utile and are easy to construct and deconstruct.

Abstract: A display device for displaying various objects, comprising a front surface, a rear surface, side surfaces, a top surface, and tiers of descending height from the rear toward the front. A slot is located behind each tier for accommodating the object. The slot has a shallow thick portion and a deep thin portion. A vertical support mechanism includes a pair of brackets which selectively pivot upward or store horizontally downward against the rear and top surfaces, and a pair of poles which are selectively mounted within pole seats in the top surface, or are stored within pole sleeves which extend into one of the side surfaces.
