Description

[Detailed Description of the Invention] Industrial field of application The present invention is intended to protect a metal flexible tube that transports a fluid such as city gas from nails that have been driven in, for example, during interior construction of a house. It relates to a flexible tube protection device that can be advantageously implemented.

Conventionally, for example, when performing interior work on a concrete house, first fix the botskock to a fixed position such as a vertical crossbar, connect a flexible pipe made of thin metal for transporting city gas to this botskock, and then connect the botskock. The wall and floor boards are mounted so that only the parts that make the connections and operations are exposed.

Problems to be Solved by the Invention During such work, the tips of the nails driven into the wall plate and the floor plate may damage the flexible tube. Due to the damage to the flexible tube, the city gas may leak.

Accordingly, an object of the present invention is to provide a flexible tube protective device capable of protecting the flexible tube from being damaged by nails or the like.

Means for Solving the Problems The present invention is a longitudinal first protective portion made of steel in the shape of a half-divided cylinder and a half-divided tubular shape, and extends along a part of the longitudinal direction of the first protection portion, and The part is connected to the first protective part by the partly flexible connecting part in the longitudinal direction, and the other side part is the first part.
A second longitudinal protection portion made of steel, which is divided from the protection portion, and a half-cylindrical tubular third steel portion, which is connected to the second protection portion and extends in a curved direction away from the first protection portion. A protective device for a flexible tube including a protective part.

According to the present invention, even if a nail or the like is driven, the tip of the nail comes into contact with the first to third protective portions made of steel, and the tip of the nail has a semicircular cylindrical outer peripheral surface of the protective portion. Bends to the outside along the line. Therefore, the flexible tube, at least a part of which is covered by the first to third protective portions, is not likely to be damaged by the tip of the nail. Further, since the second protective portion and the third protective portion are curved in a direction away from the first protective portion, the above-mentioned protection can be performed at the bent portion of the flexible tube.

Further, one side portion of the first protection portion and the second protection portion is partially connected in the longitudinal direction by a flexible connecting portion, and the other side portion is divided, so that the connecting portion is formed. Thus, the first protection part and the second protection part can be opened. Therefore, the protection device of the present invention can be attached to the flexible tube in the state where the flexible tube is arranged, and then the connecting portion can be closed to attach the first protection portion and the second protection portion to the flexible tube. .

Further, since the first protection portion and the second protection portion are partially connected by the connecting portion, the first protection portion and the second protection portion can be opened and closed with a comparatively small force, and the attachment / detachment work can be performed. Is easy.

Embodiment FIG. 1 is a perspective view of an embodiment of the present invention. For example, when performing the interior construction of a concrete house, a foundation 2 is placed on the concrete floor 1, and a joist 3 is placed on the foundation 2.
Is fixed and the vertical crosspiece 4 is erected. An L-shaped support fitting 8 is fixed to the vertical bar 4 by using an anchor bolt or the like (not shown). The support metal fitting 8 has a support portion 8a that fits into a notch 30 formed in the base 2, and a rising portion 8b that is continuous with the support portion 8a and rises along the vertical crosspiece 4, and a rising portion 8b is a box-shaped box. 5 is fixed by bolts 6 and 7. A long hole 9 extending along the longitudinal direction is formed in the support fitting 8, and the bolts 6 and 7 can be loosened to adjust the mounting position of the box box 5. A metal flexible tube 11 is connected to the box box 5 by a pipe joint 10. For example, city gas or the like is supplied to the flexible tube 11, and by operating the operation piece 12 provided in the box box 5, the city gas or the like transported from the connection port 13 by the flexible tube 11 is removed. It can be drained or blocked. A socket prepared separately is connected to the connection port 13, and the city gas or the like can be supplied to the gas combustion device via a rubber pipe or the like connected to the socket.

A protective device 20 according to the present invention is attached to the flexible tube 11. Each protective part described later of this protective device 20 has a thickness of 1.6 mm.
The above steel products can be manufactured using, for example, steel pipes. With such a protection device 20, the base 2
Even if the tip of a nail driven to fix the upper wall plate and the floor plate on the joist 3 projects toward the flexible tube 11, the tip of the nail is protected by the protection device 20 and its arc-shaped outer periphery is provided. The flexible tube 11 can be protected by bending outward along the surface.

2 is a side view of the protection device 20, FIG. 3 is a front view of the protection device 20, and FIG. 4 is a second view of the protection device 20.
5 is a side view seen from the back side of the figure, FIG. 5 is a plan view of the protective device 20, and FIG. 6 is a bottom view of the protective device 20. The protection device 20 is a first half-cylindrical first protection part.
21, which is a half-split cylinder, extends along the longitudinal direction of the first protective portion 21 partially, and one side portion 22 shown in FIG. 2 partially extends in the longitudinal direction to the first protective portion 21. Longitudinal second parts 25 are formed by connecting parts 23 and 24 made of continuous flexible material, and the other side part 25 shown in FIG. 4 is separated from the first protective part 21.
Protective part 26, half-cylindrical shape, connected to the second protective part 26,
It includes a third protection portion 27 that extends in a curved direction away from the first protection portion 21.

In attaching the protective device 20 to the flexible tube 11, the first protective portion 21 and the second and third protective portions are opened by opening the dividing surfaces 28 and 29 so as to separate from each other. As shown in FIG. 7, 26 and 27 can be opened to a width B that can be mounted on the flexible tube 11 with the connecting portions 23 and 24 as fulcrums. In such a state, as shown in FIG. 1, the protective device 20 can be easily attached to the flexible tube 11 connected to the box cock 5 attached to the vertical bar 4. In this way, after the protective device 20 is attached to the flexible tube 11 via the dividing surfaces 26 and 27, the connecting portion 2 is tightened by using a tightening tool such as pliers.
The mounting work is completed by bending the dividing planes 28, 29 in the direction in which the dividing planes 28, 29 come close to each other with 3, 24 as the fulcrum.

In the above-described embodiment, the flexible tube 11 of the protective device 20 is arranged such that the axis of the first protective portion 21 extends vertically and the free end of the second protective portion 26 is substantially perpendicular to the first protective portion 21. However, as another embodiment of the present invention, the protective device 20 may be attached to the flexible tube 11 so that the second protective portion 26 is located above, and other configurations are also possible. It may be attached to the flexible tube 11.

EFFECTS OF THE INVENTION According to the present invention, by mounting a protective device composed of a steel protective portion on a flexible tube, the flexible tube can be flexed at the tip of a nail or the like driven in the direction of the flexible tube. The pipe can be prevented from being damaged, and the safety can be improved.

Further, since the first protective portion and the second and third protective portions are connected by the connecting portion which is partially made of a flexible material on one side and are separated on the other side, After the flexible tube is attached to the attachment position, the protective device can be easily attached to the flexible tube, and the workability is improved.
