Abstract
Abstract A playground climber comprises one or more equally sized dodecahedron-shaped modules, two or more of which of equal size are joined together along a face of each. The modules are each made up of pieces of pipe of equal length attached together at their ends using a connector, each module having twelve faces and twenty corners, each face having five sides, and each corner being formed by the juncture of three pipes. Each module is a regular dodecahedron with structural members so positioned that a child can reach the members. Also, the majority of the faces of the dodecahedrons are open to permit a child to pass therethrough. The structural members of each face of each dodecahedron are spaced close enough to each other to permit a child to grasp the structural members of a regular pentagon, which forms each face of the dodecahedron, while climbing thereon.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
166 words
A playground climber, comprising a plurality of modular units connected to one another, each said modular unit being a regular dodecahedron formed of interconnecting dodecahedron structural member means having generally cylindrical climbing interconnecting struts on the face of the dodecahedron so closely spaced a child could stand on one strut and grasp any of the other struts of the face on which the child is climbing, each face of each dodecahedron unit comprising a regular pentagon and a majority of said faces being open to permit a child to pass therethrough climbing thereon and grasping of said climbing struts by a child, each said pentagon comprising five climbing struts with two said adjacent struts meeting at an angle of 108°, each said dodecahedron unit having twenty corners, and each said corner being formed by the juncture of three of said climbing struts whereby a child can climb said playground climber by grasping and placing his feet on said struts which form each face of each unit.
Claim 2
Dependent Claim
166 words
A playground climber, comprising a plurality of modular units connected to one another, each said modular unit being a regular dodecahedron formed of interconnecting dodecahedron structural member means having generally cylindrical climbing interconnecting struts on the face of the dodecahedron so closely spaced a child could stand on one strut and grasp any of the other struts of the face on which the child is climbing, each face of each dodecahedron unit comprising a regular pentagon and a majority of said faces being open to permit a child to pass therethrough climbing thereon and grasping of said climbing struts by a child, each said pentagon comprising five climbing struts with two said adjacent struts meeting at an angle of 108°, each said dodecahedron unit having twenty corners, and each said corner being formed by the juncture of three of said climbing struts whereby a child can climb said playground climber by grasping and placing his feet on said struts which form each face of each unit.
Claim 3
Dependent Claim
31 words
A playground climber in accordance with claim 1 wherein two adjacent of said modular units are in face-to-face relationship and attached to one another at the corners of the adjacent faces.
Claim 4
Dependent Claim
45 words
A playground climber in accordance with claim 2, wherein said climbing struts are formed of steel pipe, and said corners are formed of corner elements, each of which receives the ends of three said pipes, each said end being bolted to a said corner element.
Claim 5
Dependent Claim
40 words
A playground climber in accordance with claim 3, wherein said corner elements have holes passing therethrough, and wherein the connection between adjacent faces of two modular unit is by means of bolts passing through said holes in said corner elements.
Claim 6
Dependent Claim
47 words
A playground climber in accordance with claim 4, having a regular pentagon-shaped panel attached to one of the faces of at least one of said dodecahedrons, said panel being of a size equal to the size of the face of said dodecahedron to which it is attached.
