Claims19
A jungle gym having:
- a base frame group in which three cubic frames are formed continuously in the direction of a y axis by a plurality of pipes provided in the direction of an x axis, a plurality of pipes provided in the direction of the y axis and a plurality of pipes provided in the direction of a z axis;
- and
- a plurality of jungle gym joints each comprising a joint main body and a rotary member and in which the rotary member is connected rotatably to the joint main body so as to form a folding portion which is configured to be folded in one direction within an angular extent of 90 degrees,
- wherein the pipes provided in the direction of the y axis and the pipes provided in the direction of the z axis are connected to the joint main bodies,
- wherein the pipes provided in the direction of the x axis are connected to end portions of the rotary members which lie opposite to end portions where the folding portions are formed,
- wherein the folding portion is such that a flat plate portion and a bifurcate portion are connected rotatably in such a way that the flat portion is inserted into the bifurcate portion so as to be held therein,
- wherein at least one of the folding portions comprises a cylindrical cover member which is restricted from moving in the direction of an axis of the cover member while being allowed to rotate about the axis, and
- wherein the cover member comprises a restricting wall portion configured to restrict the folding portion from being folded by bringing a circumferential wall thereof into abutment with either the flat plate portion or the bifurcate portion.
