Japanese Patent JPS5320897
Kind Code:
B1
Abstract:
Playground equipment and climbing structures are described which may be disassembled and re-assembled into other forms by simple manipulation of parts. The structures are made up of the three basic elements, a large beam member having a plurality of throughbores along its length, a rod member adapted to be inserted within the throughbores of the beam member and, a pair of retaining collars, one positioned on each side of the beam member, to securely fasten the rod member within the through-bores of the beam member to prevent relative motion therebetween. The apparatus is constructed using one or more of the beam members in conjunction with one or more of the rod members having the required number of collars to hold the apparatus together. Individual play events, swings, climbing towers, ladders, parallel bars, inclined ramps, scaffolding and a myriad of other configurations, either individually or as interconnected events, may be constructed according to the teaching of this invention.
