Abstract
Abstract A folding structure useful as a "climber" or climbing type play equipment for children can be constructed so as to utilize an odd number of sides located in side edge to side edge relation. One of the sides used can be referred to as an end side; the remainder of the sides consist of an even number of pairs of sides, the sides on each of the pairs having identical external dimensions. Hinges are utilized to connect the adjacent edges of all of the sides to one another so as to form a continuous "band" type structure. The sides are of such external dimensions as to permit them to be folded between an open position in which all of the sides define a hollow structure and a collapsed position in which the sides of the pairs of sides extend adjacent to one another in a stacked relationship and in which the end side extends along side edges of the sides as they are located in this stacked configuration.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
284 words
A folding structure having a plurality of sides located in side-edge-to-side-edge relationship and a plurality of hinge means permitting said sides to be folded relative to one another in which the improvement comprises: said structure having an odd number of sides, one of said sides being a connecting side, the remainder of said sides consisting of an even number of pairs of sides, the sides in each of said pairs having identical external dimension, the sides of said pairs of sides differing in dimension, said sides of said pairs of sides being located in two series of sides of decreasing dimension in which a side edge of each of said pairs of sides is located adjacent to a side edge of a side of the next pair of sides, each of the side edges of said connecting side being located adjacent to a side edge of a side of the largest of said pair of sides, side edges of each of the sides of the smallest of said pairs of sides being located adjacent to one another, each of said hinge means connecting a side edge of one of said sides to the side edge of another of said sides so as to form an endless band which is capable of being folded, said sides being of such external dimension as to permit said sides to be folded relative to one another between an open position in which all of said sides define a hollow structure and a collapsed position in which said sides of said pairs extend adjacent to one another in stacked relationship and in which said connecting side extends between the side edges of the sides of one of said pairs.
Claim 2
Dependent Claim
284 words
A folding structure having a plurality of sides located in side-edge-to-side-edge relationship and a plurality of hinge means permitting said sides to be folded relative to one another in which the improvement comprises: said structure having an odd number of sides, one of said sides being a connecting side, the remainder of said sides consisting of an even number of pairs of sides, the sides in each of said pairs having identical external dimension, the sides of said pairs of sides differing in dimension, said sides of said pairs of sides being located in two series of sides of decreasing dimension in which a side edge of each of said pairs of sides is located adjacent to a side edge of a side of the next pair of sides, each of the side edges of said connecting side being located adjacent to a side edge of a side of the largest of said pair of sides, side edges of each of the sides of the smallest of said pairs of sides being located adjacent to one another, each of said hinge means connecting a side edge of one of said sides to the side edge of another of said sides so as to form an endless band which is capable of being folded, said sides being of such external dimension as to permit said sides to be folded relative to one another between an open position in which all of said sides define a hollow structure and a collapsed position in which said sides of said pairs extend adjacent to one another in stacked relationship and in which said connecting side extends between the side edges of the sides of one of said pairs.
Claim 3
Dependent Claim
24 words
A folding structure as claimed in claim 1 in which: said hinge means securing said sides have axes which intersect at a common point.
Claim 4
Dependent Claim
18 words
A folding structure as claimed in claim 2 in which: all of said sides have a trapezoidal shape.
Claim 5
Dependent Claim
46 words
A folding structure as claimed in claim 2 in which: there are a total of five of said sides, the sides of said pair of sides which are connected to said connecting side being larger than the sides of the other of said pair of sides.
Claim 6
Dependent Claim
23 words
A folding structure as claimed in claim 2 in which: said sides of said pairs of sides are of a quatralateral, non-trapezoidal shape.
Claim 7
Dependent Claim
16 words
A folding structure as claimed in claim 5 in which: there are nine of said sides.
Claim 8
Dependent Claim
68 words
A folding structure as claimed in claim 1 in which: said hinge means securing said sides have axes which intersect at a common point, all of said sides have a trapezoidal shape, there are a total of five of said sides, the sides of said pair of sides which are connected to said connecting side being larger than the sides of the other of said pair of sides.
Claim 9
Dependent Claim
25 words
A folding structure as claimed in claim 7 including: means for holding said sides against relative movement when said structure is in said open position.
Claim 10
Dependent Claim
59 words
A folding structure as claimed in claim 1 in which: there are nine of said sides, the sides of said pair of sides which are connected to said connecting side being larger than the sides of the other of said pairs of sides, means for holding said sides against relative movement when said structure is in said open position.
Claim 11
Dependent Claim
25 words
A folding structure as claimed in claim 1 including: means for holding said sides against relative movement when said structure is in said open position.
