Collapsible playground device

Claim 2

A playground device, comprising: a plurality of ladder sections including at least a first, a second and a third ladder section; each of said ladder sections having a pair of parallel frame members and a plurality of rungs fixed to and extending transversely across said frame members in parallel spaced relationship to each other along the length of said frame members; first attaching means for releasably attaching one end of said first ladder section directly to one end of said second ladder section with the two ladder sections at a desired angular position with respect to each other; second attaching mens for releasably attaching the opposite end of said second ladder section directly to one end of said third ladder section with the latter two ladder sections at a desired angular position with respect to each other; the free ends of each of said first and second ladder sections including a base bar of large surface area pivotably mounted to, and extending across, the parallel frame members of the respective section for supporting the playground device on the ground; the pair of frame members of each ladder section being bars formed with flat, parallel, outer surfaces at each end where coupled to another ladder section; each of the flat surfaces of one pair of frame members at each coupled end being formed with a first opening, and with a plurality of further openings arranged in a circular array; each of the flat surfaces of the other pair of frame members at each coupled end being formed with a first opening alignable with said first opening of said one pair of frame members, and with another opening alignable with a selected one of said circular array of openings in said one pair of frame members; said first and second attaching means each comprising a pivot pin passing through each of said aligned first openings in the coupled ends of the frame members, and a locking pin passing through said selected one of the circular array of openings in said one pair of frame members and said aligned other opening in said other pair of frame members for locking the two ladder sections at each coupled end at a selected angular position with respect to each other.

Claim 3

The device according to claim 1, wherein said first and second ladder sections include rigid rungs, and said third ladder section includes rope rungs.

Claim 4

The device according to claim 1, further including a slide section attachable at one end to one of the rungs of one of the ladder sections and restable at the other end on the ground for supporting said slide section at an incline.

Claim 5

A playground device, comprising: a plurality of ladder sections including at least a first, a second and a third ladder section; each of said ladder sections having a pair of parallel frame members and a plurality of rungs fixed to and extending transversely across said frame members in parallel spaced relationship to each other along the length of said frame members; first attaching means for releasably attaching one end of said first ladder section directly to one end of said second ladder section with the two ladder sections at a desired angular position with respect to each other; second attaching means for releasably attaching the opposite end of said second ladder section directly to one end of said third ladder section with the latter two ladder sections at a desired angular position with respect to each other; the free ends of each of said first and second ladder sections including a base bar of large surface area pivotably mounted to, and extending across, the parallel frame members of the respective section for supporting the playground device on the ground; the pair of frame members of each ladder section being bars formed with flat, parallel, outer surfaces at each end where coupled to another ladder section; each of the flat surfaces of one pair of frame members at each coupled end being formed with a first opening, and with a plurality of further openings arranged in a circular array; each of the flat surfaces of the other pair of frame members at each coupled end being formed with a first opening alignable with said first opening of said one pair of frame members, and with another opening alignable with a selected one of said circular array of openings in said one pair of frame members; said first and second attaching means each comprising a pivot pin passing through each of said aligned first openings in the coupled ends of the frame members, and a locking pin passing through said selected one of the circular array of openings in said one pair of frame members and said aligned other opening in said other pair of frame members for locking the two ladder sections at each coupled end at a selected angular position with respect to each other; and a slide section attachable at one end to one of the rungs of one of the ladder sections and restable at the other end on the ground for supporting said slide section at an incline.

Claim 6

A playground device, comprising: a plurality of ladder sections including at least a first, a second and a third ladder section; each of said ladder sections having a pair of parallel frame members and a plurality of rungs fixed to and extending transversely across said frame members in parallel spaced relationship to each other along the length of said frame members; first attaching means for releasably attaching one end of said first ladder section directly to one end of said second ladder section with the two ladder sections at a desired angular position with respect to each other; second attaching means for releasably attaching the opposite end of said second ladder section directly to one end of said third ladder section with the latter two ladder sections at a desired angular position with respect to each other; the free ends of each of said first and second ladder sections including a base bar of large surface area pivotably mounted to, and extending across, the parallel frame members of the respective section for supporting the playground device on the ground; the pair of frame members of each ladder section being bars formed with flat, parallel, outer surfaces at each end where coupled to another ladder section; each of the flat surfaces of one pair of frame members at each coupled end being formed with a first opening, and with a plurality of further openings arranged in a circular array; each of the flat surfaces of the other pair of frame members at each coupled end being formed with a first opening alignable with said first opening of said one pair of frame members, and with another opening alignable with a selected one of said circular array of openings in said one pair of frame members; said first and second attaching means each comprising a pivot pin passing through each of said aligned first openings in the coupled ends of the frame members, and a locking pin passing through said selected one of the circular array of openings in said one pair of frame members and said aligned other opening in said other pair of frame members for locking the two ladder sections at each coupled end at a selected angular position with respect to each other; and a slide section attachable at one end to one of the rungs of one of the ladder sections and restable at the other end on the ground for supporting said slide section at an incline.

Claim 7

The device according to claim 4, wherein said first and second ladder sections include rigid rungs, and said third ladder section includes rope rungs.
