Abstract
Abstract Children's playground toys constructed from used tires are coated with an epoxy resin coating which is resistant to abrasion, temperature fluctuations and which adheres firmly during flexing and stretching of the tires during use. The coating enhances the visual appearance and functional characteristics of the equipment and prevents rub-off from the tire bodies onto the skin or clothing of children using the playground toys.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
142 words
Children's playground equipment comprising: at least two tire cubes each comprising six cubically arranged tire bodies, the four vertical bodies of which are connected to the two horizontal tire bodies through adjacent shoulder portions thereof and said tire cubes being spaced apart from each other so that adjacent vertical tire bodies of the respective tire cubes are substantially coaxial, fastening means interconnecting said spaced apart adjacent vertical tire bodies, said fastening means comprising a plurality of horizontal pipe means interconnecting said adjacent vertical tires through the sidewall portions thereof, and a substantially uniform coating of a cured epoxy resin on at least the exterior surfaces of said tire bodies, said coating having been applied as a 50/50 mixture of an epichlorohydrin-bisphenol epoxy resin and a polyamide curing agent which is the reaction product of a dimerized fatty acid and an aliphatic amine.
Claim 2
Dependent Claim

Claim 4
Dependent Claim
38 words
The invention set forth in claim 1 wherein said playground equipment includes more than two of said tire cubes and wherein at least one of said tire cubes has adjoining vertical tire bodies interconnected to adjacent tire cubes.
Claim 5
Dependent Claim
95 words
Children's playground equipment comprising: at least two spaced apart, substantially coaxial tire bodies, fastening means interconnecting said spaced apart tire bodies, said fastening means comprising a plurality of pipe means interconnecting adjacent ones of said tire bodies through the sidewall portions thereof, and a substantially uniform coating of a cured epoxy resin on at least the exterior surfaces of said tire bodies, said coating having been applied as a 50/50 mixture of an epichlorohydrin-bisphenol epoxy resin and a polyamide curing agent which is the reaction product of a dimerized fatty acid and an aliphatic amine.
Claim 6
Dependent Claim
95 words
Children's playground equipment comprising: at least two spaced apart, substantially coaxial tire bodies, fastening means interconnecting said spaced apart tire bodies, said fastening means comprising a plurality of pipe means interconnecting adjacent ones of said tire bodies through the sidewall portions thereof, and a substantially uniform coating of a cured epoxy resin on at least the exterior surfaces of said tire bodies, said coating having been applied as a 50/50 mixture of an epichlorohydrin-bisphenol epoxy resin and a polyamide curing agent which is the reaction product of a dimerized fatty acid and an aliphatic amine.
