Abstract
Abstract A simple structure which is in itself a recreational unit and which is adaptable for mating with like structures wherein infinitely variable combinations and permutations of recreational facilities are provided. The basic unit generally includes a hollow cuboctahedron with each of the square faces including a regular centrally located opening therethrough. Traverseway members for access to or egress from the interior of the cuboctahedrons may be fastened thereto either at one end of a traverseway or, if desired, at both ends thereby bridging the gap between cuboctahedrons. The traverseways may be hollow tubular or semicircular in cross section and if fastened at one end only can be utilized as a slide. The free end of the slide includes a depending support.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
56 words
A recreational unit comprising a hollow cuboctahedron having six equal square faces and eight equal regular triangular faces, said faces being so dimensioned as to accommodate a child within the cuboctahedron, each of said square faces including a substantially centralized opening therethrough, each of said openings including a rounDed inner edge with a protective sheath thereon.
Claim 2
Dependent Claim
56 words
A recreational unit comprising a hollow cuboctahedron having six equal square faces and eight equal regular triangular faces, said faces being so dimensioned as to accommodate a child within the cuboctahedron, each of said square faces including a substantially centralized opening therethrough, each of said openings including a rounDed inner edge with a protective sheath thereon.
Claim 3
Dependent Claim
146 words
A recreational unit comprising a hollow cuboctahedron having six equal square faces and eight equal regular triangular faces, said faces being so dimensioned as to accommodate a child within the cuboctahedron, each of said square faces including a substantially centralized opening therethrough, said recreational unit further including means forming a traverseway for access to or egress from the interior of the cuboctahedron, said traverseway including means defining a portal at one end thereof, said portal being of similar dimensions to an opening of a square face of the cuboctahedron, a flange peripherally projecting from said portal, said flange being of substantially similar dimensions to a square face of the cuboctahedron, and means to connect said traverseway to the cuboctahedron with an opening of the cuboctahedron in registry with the portal, said connecting means including means to link said flange to a square face of the cuboctahedron.
Claim 4
Dependent Claim
146 words
A recreational unit comprising a hollow cuboctahedron having six equal square faces and eight equal regular triangular faces, said faces being so dimensioned as to accommodate a child within the cuboctahedron, each of said square faces including a substantially centralized opening therethrough, said recreational unit further including means forming a traverseway for access to or egress from the interior of the cuboctahedron, said traverseway including means defining a portal at one end thereof, said portal being of similar dimensions to an opening of a square face of the cuboctahedron, a flange peripherally projecting from said portal, said flange being of substantially similar dimensions to a square face of the cuboctahedron, and means to connect said traverseway to the cuboctahedron with an opening of the cuboctahedron in registry with the portal, said connecting means including means to link said flange to a square face of the cuboctahedron.
Claim 5
Dependent Claim
38 words
A recreational unit constructed in accordance with claim 2 wherein the traverseway further includes a second flange at the other end thereof, said second flange adapted to be linked to a square face of a second similar cuboctahedron.
Claim 6
Dependent Claim
37 words
A recreational unit constructed in accordance with claim 2 wherein the linking means includes apertures through a square face of the cuboctahedron and the flange, said apertures adapted to be registered to thereby accept a linking member.
Claim 7
Dependent Claim
35 words
A recreational unit constructed in accordance with claim 2 wherein the flange intersects the longitudinal axis of the traverseway at an acute interior angle, the traverseway thereby forming an inclined egress slide from the cuboctahedron.
Claim 8
Dependent Claim
18 words
A recreational unit constructed in accordance with claim 5 wherein the traverseway is substantially semicircular in cross section.
Claim 9
Dependent Claim
46 words
A recreational unit constructed in accordance with claim 5 wherein the traverseway includes a depending support, said support projecting from the underside of the traverseway and engaging a supporting surface, whereby the weight of a child sliding along the traverseway is borne by the supporting surface.
