良することが求められていた。Problems to be Solved by the Invention In the conventional folding pipe, the sliding operation rod is passed through the sleeve, and both ends of the folding pipe are fitted into a pair of vertically long holes provided opposite to both side surfaces of the pipe end, The sleeve is made to advance and retreat by fitting a hooking tool having a ring formed at both ends to the outer ends of the slide operating rods protruding from both side surfaces of the pipe. Therefore, according to this conventional product, the slide operation rod must be passed through the sleeve,
The fact that a pair of vertically elongated holes must be provided on both sides of the pipe, and that hooks with rings at both ends must be provided separately make the cost high and inconvenient to use. Therefore, it has been required to improve a folding pipe of this kind so as to have a simple structure and be easy to operate.

によって降下させるようにする場合もある。In the figure, A and B are two pipes to be folded, 1 is a bearing provided on one side of an end portion a of one pipe A, and a bearing having an axis line orthogonal to the pipe, 2 is a bearing penetrating the bearing 1. By crimping both ends thereof to the connection holding piece 3, the hinge shaft integrally provided at the end b of the other pipe B, the connection holding piece 3 is connected to one pipe A as shown in FIGS. It has a semicircular cross section that is superposed on the other side surface of the end a of the pipe B and is integrally extended from the end b of the pipe B in the extension direction. Reference numeral 4 denotes a sleeve slidably fitted in the end portion b of the one pipe A so as to move in and out from the end portion b of the pipe B. The slide operating rod 6 projecting only to one side is fitted with the pipe B so that the sliding operating rod 5 can be slidably fitted.
The vertical hole 5'provided on one side of the end b of the slide handle 5'is a knob for operation formed on the outer end of the slide operating rod 5, and 7 is a hook-shaped handle provided at the end of the vertical hole 6 for attaching the slide operating rod 5. A hooking portion 8 hooked in each of the forward movement position and the backward movement position, 8 has a fixed end in the middle of the pipe B, and is fitted in the end portion b of the pipe B,
As shown in FIG. 2, the slide operating rod 5 is brought into contact with the slide operating rod 5,
The push spring 8 always biases the sleeve 4 in the projecting direction.
In some cases, the sleeve 4 may be lowered by its own weight from the end b of the pipe B located above.

う実用的効果がある。Effect of the Invention As described above, according to the present invention, one pipe and the other pipe are hinged at one end of both ends to be foldable and the other side is provided with a connection holding piece having a semicircular cross section. Then, in the folding pipe in which the sleeve that fits into the end is fitted to the end of one pipe, a vertically elongated hole is provided in one side of the pipe into which the sleeve is fitted, and the vertically elongated hole is formed from one side of the sleeve. Since the protruding slide operation rod is slidably fitted and the outer end of the slide operation rod is formed as a knob for operation, compared with the conventional product in which a vertically elongated hole and a slide operation rod are provided on both sides. The structure is simplified and the restrictions on the installation position are reduced, so that the cost can be reduced. In addition, according to the present invention, the use of the hooking device can be omitted, so that there is a practical effect that the folding operation is easy.
