Abstract
Abstract A molded tub or play pool structure having a pair of integrally molded recreational structures including sliding surfaces and steps leading up to the sliding surfaces is disclosed herein. The recreational structures in cooperation with two U-shaped end walls define a water-retaining pool. More specifically, the sliding surfaces are oppositely oriented, one of the sliding surfaces permitting sliding entry into the pool, the other sliding surface permitting sliding egress from the pool.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
166 words
A unitary recreational structure, comprising a. a first step-slide structure including integrally molded first steps and risers ascending to a first inclined sliding surface; b. a second step-slide structure including integrally molded second steps and risers ascending to a second sliding surface; c. a first, generally U-shaped common side wall supporting the first lateral edges of said steps, risers, and sliding surfaces of said first and second structures; d. a second, generally U-shaped common side wall supporting the second lateral edges of said steps, risers, and sliding surfaces of said first and second step-slide structures; e. said U-shaped walls being oppositely oriented with the ends of said first side wall juxtaposed with the ends of said second side wall; f. an interior floor joining the lowermost interior edges of said first and second side wall and the lowermost edges of said first and second step-slide structures; g. whereby said first side wall, second side wall, first stepslide, second step-slide, and floor define a fluid-retaining pool therebetween.
Claim 2
Dependent Claim
166 words
A unitary recreational structure, comprising a. a first step-slide structure including integrally molded first steps and risers ascending to a first inclined sliding surface; b. a second step-slide structure including integrally molded second steps and risers ascending to a second sliding surface; c. a first, generally U-shaped common side wall supporting the first lateral edges of said steps, risers, and sliding surfaces of said first and second structures; d. a second, generally U-shaped common side wall supporting the second lateral edges of said steps, risers, and sliding surfaces of said first and second step-slide structures; e. said U-shaped walls being oppositely oriented with the ends of said first side wall juxtaposed with the ends of said second side wall; f. an interior floor joining the lowermost interior edges of said first and second side wall and the lowermost edges of said first and second step-slide structures; g. whereby said first side wall, second side wall, first stepslide, second step-slide, and floor define a fluid-retaining pool therebetween.
Claim 3
Dependent Claim
