Abstract

(57) [Problem] To provide a flexible hose which has a simple structure, can change its shape by applying an external force, and can maintain the changed shape when the external force is removed. SOLUTION: An internal space 16 of a hose body 12 to which a connecting member 14 is fixed at one end accommodates a linear shape holding member 18 which is irreversibly deformed. One end of the shape holding member 18 is fixed to the connection member 14 and the other end is a free end. Thus, when an external force is applied to the hose body 12 to bend the hose body 12 and thereafter the external force is removed, the shape holding member 18 can maintain the bent shape against the return force of the hose body 12.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a flexible hose that can maintain an arbitrary shape in a space.

[0002]

[Prior art]

 Conventionally, hoses for sending liquids such as water and gases such as air and gas have generally been made of a flexible material so that they can pass through any place. Depending on the type of hose, for example, a connection means such as a male screw or a female screw is attached to both ends of a high-pressure hose or the like.

[0003]

[Problems to be solved by the invention]

 When one end of the hose is higher than the floor or ground, the hose is flexible and some support must be used to support the end of the hose near the end, and a support must be provided. In addition, there is a case where it is desired to keep the hose in a free shape in a space, but there is a disadvantage that the hose cannot be kept in a free shape in a space because the hose is flexible.

[0004] The present invention has been made in view of the above points, and an object of the present invention is to provide a flexible hose that can change its shape by applying an external force and maintain the changed shape when the external force is removed. .

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention fixes a connecting member at one end of a hose body, and accommodates a linear shape holding member that is irreversibly deformed in an inner space of the hose body. One end of the deformable linear shape holding member is fixed to the connection member, and the other end is a free end.

[0006]

[Embodiment of the invention]

 Next, the flexible hose according to the present invention will be described with reference to the drawings. FIG. 1 is a sectional view showing an embodiment of the flexible hose according to the present invention, and FIG. 2 is a sectional view showing a state in which the flexible hose according to the present invention is bent. The flexible hose 10 according to the present invention includes a hose body 12, a connection member 14 fixed to one end of the body 12, and a connection member 14 housed in an internal space 16 of the hose body 12. And an irreversibly deformable linear shape holding member 18 for fixing the shape. The linear shape retaining member 18 that deforms irreversibly bends in response to a force in the bending direction, for example, and retains the bent shape when the force is removed. The shape holding member 18 is formed of a thickness or a material that holds the bent state against the force of the hose body 12 that attempts to return to the original state when the shape holding member 18 is bent. The thickness of the shape maintaining member 18 is preferably, for example, about 3 to 5 mm in diameter, but the thickness is not limited to this. The material of the shape maintaining member 18 is preferably copper, but is not limited to copper or metal.

The connection member 14 includes, for example, a male screw, a female screw, a metal fitting with a nozzle, and the like, but is not limited thereto. The connecting member 14 and the hose body 12 are fixed by caulking, but the fixing method is not limited to this. One end of the irreversibly deformable linear shape holding member 18 is fixed to the cylindrical connecting member 14 by welding or the like. In order to be able to maintain a shape such as bending at any position along the length of the flexible hose 10, it is desirable that the length of the shape holding member 18 be substantially the same as the length of the hose body 12. The other end of the shape holding member 18 is a free end that is not fixed to any member. In FIGS. 1 and 2, the connection members 14 are provided at both ends of the hose body 12, but the connection members 14 may be provided at least at one end of the hose body 12.

In the present invention, a force is applied to both ends of a straight flexible hose 10 as shown in FIG. 1, and the hose is bent into a U shape as shown in FIG. 2, for example. Thereafter, even if the force is removed, the hose body 12 tries to return to the original state, but the shape retaining member 18 resists the force to return to the original state of the hose body 12, and the flexible hose 10 as a whole shown in FIG. Holds U-shape. The shape holding member 18 provided inside the hose body 12 is easy to bend and can hold the bent shape as it is after being bent, and does not adversely affect water when water is passed through the hose. Considering the points, it is desirable to adopt a material such as copper.

It is to be noted that the hose of the present invention includes all flexible tubular articles (such as pipes).

[0010]

[Effect of the invention]

 As described above, according to the flexible hose of the present invention, the shape can be changed by applying an external force, and the changed shape can be maintained when the external force is removed. As a result, the hose can be held in a free shape, and the hose can be held in a free position in a space without a supporting member required conventionally. Further, compared to the conventional hose, since only one linear shape holding member that is irreversibly deformed is added, the above-mentioned effect can be achieved with almost no increase in cost.

FIG. 2 is a sectional view showing a state in which the flexible hose according to the present invention is bent.
