Claims

[Scope of utility model registration request]

A large number of cylindrical paper tubes 2 cut into predetermined lengths
and a large number of synthetic resin joints that connect these paper tubes 2 in a three-dimensional lattice pattern, including a 3-leg end joint 3, a 4-leg intermediate joint 4, a 5-leg intermediate joint 5, and a 6-leg intermediate joint 6. Joint 3, 4th leg intermediate joint 4, 5th leg intermediate joint 5, and 6th leg intermediate joint 6 at the ends of the 3 legs of the joint are shell-shaped joint center portions 3a, 4a, 5a, 6.
a, a leg that extends in at least one of the vertical directions from the joint center portions 3a, 4a, 5a, and 6a, and a leg that extends in at least one of the left and right directions from the joint center portions 3a, 4a, 5a, and 6a; Center part 3a, 4
In this indoor gym, the indoor gym has legs extending in at least one of the front and rear directions from a, 5a, and 6a, and each leg is formed into a cylindrical shape that fits inside the end of the paper tube 2. There is at least one stage between the distal end and the proximal end where the diameter is gradually increased from the distal end to the proximal end until the diameter becomes slightly larger than the inner diameter of the paper tube, and then the diameter is reduced from the maximum diameter. The diameter portion 8 is formed to protrude uniformly and continuously over the entire circumference, so that the outer surface of the joint center portions 3a, 4a, 5a, 6a is continuous with the outer circumferential surface of the paper tube 2 fitted onto each leg. An indoor gym that is characterized by being formed.
