  Reference sign K indicates a handrail structure. The handrail structure K is configured by attaching a handrail T to a wall surface as an attachment portion. The handrail structure K shown in the present embodiment is configured by attaching the handrail T to a wall surface having a curved surface, but the shape of the wall surface is not particularly limited.

The handrail T includes a pipe structure 1 and fixtures 2... That are fixtures for fixing the pipe structure 1. A plurality of the fixing brackets 2 are provided at predetermined positions so that the pipe structure 1 can be fixed to the surface of the wall surface described above and along the inclination angle of the stairs.
The handrail T is configured by fixing the pipe structure 1 to the fixing metal fittings 2... In a state where the pipe structure 1 is bent along the surface of the wall surface and along the inclination angle of the staircase.

  The tube structure 1 includes a tube body 10 having a required length of deformability. In this embodiment, the tubular body 10 has a length of about 20 m and uses a light-impermeable hose made of a synthetic resin and having a diameter (outer diameter) of about 30 mm. In the tube body 10, air holes 100 are formed at a plurality of locations at required intervals to draw out air from the hollow portion.

  Inside the hollow portion of the tube body 10, a metal core 11 is provided so as to penetrate therethrough. The core material 11 is a wire 110 that is a linear body having required tensile strength and deformability, and a substantially “ten” shape that allows the wire 110 to be disposed at a position that passes through a substantially central portion in the tube body 10. And a spiral body 112 formed by winding a wire rod in a coil shape at a required pitch so that the diameter is slightly smaller than the inner diameter of the tube body 10.

  The core member 11 is disposed at a position where the wire 110 passes through the substantially central portion of the spiral body 112 by passing the wire 110 through the spiral body 112 and interposing the spacer 111 between the spiral body 112 and the wire 110. Are combined. Specifically, the spacer 111 is combined by welding the vicinity of the intersection to the wire 110 and welding the four ends to corresponding portions of the spiral body 112. The spacers 111 are attached at a required pitch in the length direction of the wire 110.

  The core material 11 is put in the tube body 10 in a combined state, so that the outer side of the spiral body 112 substantially hits the inner surface of the tube body 10, so that even if the tube body 10 is bent, the wire 110 is not bent.
