DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe whose length can be freely adjusted and which can be used as a long object even in a narrow place.

[0002]

2. Description of the Related Art Conventionally, when using a long pipe,
In general, a plurality of short pipes of about 2 m are connected to be used as a long pipe of about 3 to 5 m. Alternatively, it is used by cutting a long pipe from the beginning as needed. These pipes are used, for example, when scissors are attached to the ends of pipes to cut branches at high altitudes, when insect nets are attached to the ends, or when wires or cables such as electric wires are used indoors. This is the case.

[0003]

However, such a conventional example has the following problems.
That is, although it is possible to easily form a long pipe by connecting short pipes, it is still inconvenient to carry a plurality of pipes even with a short pipe,
In particular, there is a problem of lack of portability.

[0004] Further, even when a fixed-length and long-length pipe is cut in accordance with a required length, the cut remaining pipe is usually short and has no use purpose. The pipe is discarded and wasted, causing a problem from the viewpoint of resource saving. Further, when wiring cords such as electric wires indoors with a pipe, it is necessary to lay the pipe while swinging a long pipe, which is problematic in workability. In particular, pipes made of synthetic resin or metal cannot be bent, and when pipes are piped through holes in the side wall under the floor, they cannot be piped using long pipes because they hit the walls of neighbors. was there.

The present invention has been made in view of the above points, and has as its object to provide a pipe which is excellent in portability and can easily form a long pipe even in a narrow place.

[0006]

Therefore, in the pipe according to the first aspect of the present invention, a strip-shaped pipe material 1 made of a flexible synthetic resin is wound in advance, and both ends of the strip-shaped pipe material 1 on the distal end side. It is characterized in that they are sequentially joined along the longitudinal direction to form a cylindrical pipe body 10. Thereby, the long pipe main body 10 can be easily formed from the band-shaped pipe material 1 in the wound state.

Further, in the pipe according to the second aspect, fastener elements 2 are attached to both ends of the strip-shaped pipe material 1 over substantially the entire length in the longitudinal direction of the strip-shaped pipe material 1, and the slide element 6 is slidable by the slider 6. The pipe body 10 is formed by engaging the elements 2. Therefore, just by engaging the elements 2 at both ends of the strip-shaped pipe material 1 with the slider 6, both ends of the strip-shaped pipe material 1 can be firmly joined. The long-sized pipe main body 10 can be easily formed.

Further, in the pipe according to the third aspect, at least three or more thick portions 20 are integrally provided on the strip-shaped pipe material 1 along the longitudinal direction of the strip-shaped pipe material 1. I have. Thereby, when the cylindrical pipe main body 10 is formed, the strength of the pipe main body 10 is improved by the thick-walled portion 20, and the pipe main body 10 can be reliably prevented from being bent in the middle.

In the pipe according to the fourth aspect, the thick portion 2
Since the metal plate 23 having elasticity is embedded integrally over substantially the entire length in the longitudinal direction of the thick portion 20, the thick portion 2
The strength of the pipe main body 10 can be further improved by the metal plate 23 embedded in the inner portion 0 as compared with the case where only the thick portion 20 is provided, and the pipe main body 10 can be reliably prevented from being bent in the middle.

[0010] In the pipe according to the fifth aspect, the element 2 at one end of the strip-shaped pipe member 1 is engaged with the element 2 at an arbitrary position at the other end. And Thus, simply preparing the strip-shaped pipe material 1 having one type of width dimension,
Pipe bodies 10 having different diameters can be easily formed.

In the pipe according to the sixth aspect, the strip-shaped pipe material 1 made of a flexible metal plate is wound in advance, and both ends of the strip-shaped pipe material 1 on the tip side are sequentially joined along the longitudinal direction. Thus, a cylindrical pipe body 10 is formed, whereby a long pipe body 10 can be easily formed from the band-shaped pipe material 1 in a wound state. Can be.

Further, in the pipe according to the present invention, fastener elements 2 are attached to both ends of the strip-shaped pipe material 1 over substantially the entire length of the strip-shaped pipe material 1 in the longitudinal direction, and the slider 6 is slidable by the slider 6. The pipe body 10 is formed by engaging the elements 2. Therefore, just by engaging the elements 2 at both ends of the strip-shaped pipe material 1 with the slider 6, both ends of the strip-shaped pipe material 1 can be firmly joined. The long-sized pipe main body 10 can be easily formed.

[0013]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 2 is a perspective view of the band-shaped pipe member 1 before forming a cylindrical pipe. The band-shaped pipe member 1 is formed of a flexible synthetic resin. The strip-shaped pipe material 1 is wound before forming the pipe, so that it is easy to carry. At both ends of the strip-shaped pipe member 1, so-called fastener elements 2 are attached over the entire length in the longitudinal direction. As shown in FIG. 3, the element 2 has fixed pieces 3 integrally formed on the upper and lower sides, and a concave portion 4 is formed on one surface. On the opposite surface of the concave portion 4, a convex portion that fits with the concave portion 4 of the opposing element 2 is provided in a protruding manner. The element 2 is made of metal.

At both ends of the strip-shaped pipe material 1, projecting ridges 5 are integrally formed by extrusion molding. The fixing pieces 3 of the element 2 are sandwiched between the projecting ridges 5 at predetermined intervals from above and below. Each element 2 to the strip-shaped pipe material 1
Are fixed to the ends on both sides continuously. Also,
The element 2 may be attached to the end of the strip-shaped pipe material 1 without forming the ridge 5. The element 2 may be formed of a synthetic resin. In this case, the tip of the fixing piece 3 of the element 2 is welded to the end of the strip-shaped pipe material 1 so that the element 2 is connected to the end of the strip-shaped pipe material 1. It is fixed to the part.

A slider 6 is slidably provided at one end of the strip-shaped pipe member 1, and a stopper 7 meshing with the slider 6 is fixed to the end of the other end of the strip-shaped pipe member 1. Have been.

The strip-shaped pipe material 1 itself is strip-shaped and flat, but when a cylindrical pipe is formed as described later, the strip-shaped pipe material 1 expands by its own restoring force so as to be able to stand alone and has a flat shape. It has a thickness such that For this reason, after the band-shaped pipe material 1 is wound, the wound state is maintained by a band (not shown) or the like in the wound state.

Next, a case where a cylindrical pipe body 10 is formed from the strip-shaped pipe material 1 will be described with reference to FIG. First, as in the case of a normal fastener, the slider 6 on the distal end side of the strip-shaped pipe material 1 is engaged with the lower stopper 7, and the slider 6 is slid to the winding side. As a result, the elements 2 at both ends of the strip-shaped pipe material 1 mesh with each other, and both ends of the strip-shaped pipe material 1 are sequentially joined along the longitudinal direction. By joining the elements 2, a pipe body 10 having a cylindrical shape on the tip side from the slider 6 is formed.
It is formed as. When the slider 6 is slid to the end, an upper stopper (not shown) similar to the fastener is formed on the element 2 side of the last part of the strip-shaped pipe material 1, and the slider 6 is further slid by the upper stopper. Is regulated, one pipe main body 10 can be formed from one wound strip-shaped pipe material 1.

By the way, the strip-shaped pipe material 1 is
A strip-shaped pipe material 1 having a different length in units of cm or 1 m is formed and wound up. The length of the strip-shaped pipe material 1 is, for example, from a minimum of 50 cm to a maximum of about 10 m, and the strip-shaped pipe materials 1 having different lengths are formed and wound in advance. In addition, various width dimensions of the strip-shaped pipe material 1 are prepared in advance. By doing so, a plurality of types of pipe bodies 10 having different inner diameters can be formed.

When the pipe main body 10 is formed, the pipe main body 10 itself has a restoring force acting in a direction orthogonal to the longitudinal direction of the pipe main body 10 at each portion where each element 2 is engaged. Since the restoring force does not work only at the last end of the pipe body 10,
Once the pipe main body 10 is formed, each element 2 is surely maintained in the meshed state, and the element 2 is not easily detached.

The pipe body 10 thus formed
As shown in FIGS. 4 and 5, the pipe main body 10 can be self-supported without being bent in the middle, and the pipe main body 10 can be used as a long pipe from the flat band-shaped band-shaped pipe material 1. . In addition, since the strip-shaped pipe material 1 is wound before the pipe body 10 is formed, it is excellent in portability and there is no need to carry it as a long pipe.

FIG. 6 shows an example of use of the pipe of the present invention, in which a cord or cable such as an electric wire is inserted under the floor into the pipe body 10 and wired. This is a case where a pipe is inserted and piped from an opening 13 such as a vent hole formed in a lower portion of the outer wall 12. The housing situation in Japan is bad, and the site is particularly small as shown in the illustration.
In general, the passage 15 through which one person can pass is provided. When the underfloor piping is performed from such a narrow passage 15 through the opening 13, the pipe body 10 of the present invention is effective.

That is, the strip-shaped pipe material 1 is carried into the passage 15 in a wound state, and the slider 6 is slid while extending the strip-shaped pipe material 1 from the outside of the opening 13 to form the cylindrical pipe body 10. To go. Then, piping is performed under the floor while forming the pipe body 10. Although piping from the narrow passage 15 to the opening 13 is impossible with a conventional long pipe, the piping 15 is formed as a long pipe under the floor even if the passage 15 is narrow due to the strip-shaped pipe material 1 of the present invention. This makes it possible to easily lay a long pipe. In addition, since the material of the pipe body 10 is made of synthetic resin, it is advantageous in terms of insulation when wiring electric wires and the like, and the pipe body 10 is formed while the electric wires are laid along the inside of the pipe body 10. It is also effective as a guide for electric wires. Thus, the pipe according to the present invention is particularly suitable for a pipe for piping.

The pipe body 10 can be used not only for pipes for electric wires but also for cutting high places by attaching scissors to the tip of the pipe body 10.
Further, an insect net can be attached to the tip of the pipe body 10. In this case, only the insect net and the wound strip-shaped pipe member 1 are used, and the portability is extremely excellent. In particular, the portability can be exhibited when going far away.

(Second Embodiment) FIGS. 7 and 8 show a second embodiment.
In this embodiment, three thick portions 20 are integrally formed along the longitudinal direction of the strip-shaped pipe member 1. A thin portion 21 is formed between the thick portions 20 and the thin portions 21 on both sides are provided with elements 2 constituting a fastener as in the previous embodiment. The upper surface of the thick portion 20 (the inner surface side when the pipe body 10 is formed) is a curved surface that is depressed inward, and the lower surface of the thick portion 20 (the outer surface side when the pipe body 10 is formed) protrudes outward. Curved surface. Furthermore, the thin portion 21 has a function just like a hinge, so that the strip-shaped pipe member 1 can be easily formed into a cylindrical shape.

The thickness of the thick portion 20 is also small enough to wind the strip-shaped pipe material 1, so that the strip-shaped pipe material 1 can be easily wound. Thereby, when the pipe main body 10 is formed as shown in FIG.
0 is the core of the pipe body 10 over the entire length in the longitudinal direction, and prevents the pipe body 10 from being bent when formed into a long object. Further, the thick portion 20 is formed into a so-called arch shape by the thick portion 20, and the strength is increased. Further, since the outer surface of each thick portion 20 is curved in a direction protruding outward, when the pipe main body 10 is formed, a beautiful cylindrical shape can be formed even if the member is slightly thick. In FIGS. 8 to 10, the thickness of the thick portion 20 and the thickness of the metal plate 23 are shown thicker for easy understanding, but they are actually thinner than shown.

(Third Embodiment) FIG. 9 shows a third embodiment, in which an elastic metal plate 23 is provided in a thick portion 20.
Is embedded over substantially the entire length of the thick portion 20 in the longitudinal direction. The strip-shaped pipe member 1 is formed by integrally molding the metal plate 23 and the synthetic resin. The metal plate 23
Is curved laterally. Metal plate 2 on strip-shaped pipe material 1
By providing the pipe body 3, in addition to the effect of FIG. 8, when the pipe body 10 is formed, the rigidity can be further increased, and the pipe body 10 having a longer length than the case of FIG. Can be easily formed.

In FIGS. 7 to 10, three thick portions 20 are used. However, at least three thick portions 20 are sufficient. This is because a cylindrical shape can be formed if there are three thick portions 20, and it goes without saying that four or more thick portions 20 may be formed.

(Fourth Embodiment) FIG. 11 shows another example of a method of joining the strip-shaped pipe material 1. Since the strip-shaped pipe material 1 is formed of a synthetic resin, the unevenness is fitted. In this case, both ends of the strip-shaped pipe member 1 are joined to form a pipe body 10. That is, FIG.
As shown in FIG. 1A, locking holes 26 are formed at one end of the strip-shaped pipe member 1 at predetermined intervals over the entire length, and the other ends of the strip-shaped pipe member 1 are engaged with the locking holes 26. Wedge-shaped projections 27 are integrally provided at predetermined intervals over the entire length. In addition, since the material of the strip-shaped pipe member 1 is flexible, the projection 27 is inserted and locked in the locking hole 26 by pressing the projection 27 against the locking hole 26.

FIG. 11B shows a case where the thickness is increased only at the portion of the locking hole 26, and FIG. 11C shows a case where the shape of the projection 27 is spherical. FIGS. 11A to 11C show a method of joining both ends of the strip-shaped pipe material 1.
May be combined. FIG. 12 is a perspective view showing a case where the projection 27 and the locking hole 26 are engaged with each other to form the pipe main body 10 from the strip-shaped pipe material 1. In the drawings, the portion of the protrusion 27 is indicated by a solid line for easy understanding.

(Fifth Embodiment) In each of the above embodiments, when forming pipe bodies 10 having different diameters, it is necessary to use a strip-shaped pipe material 1 having a width corresponding to a desired diameter. However, in this embodiment, the pipe main body 1 having a different diameter can be obtained by using only one kind of the strip-shaped pipe material 1 having a width.
0 can be formed.

In FIG. 13, when the ends of both ends of the strip-shaped pipe material 1 are point A and point B, and the element 2 is joined at the points A and B, a pipe body 10 as shown in FIG. 1 is formed. By performing the first joining at the portion at the point A and the position behind the point B, the pipe main body 10 having a different width can be formed with one kind of the strip-shaped pipe material 1 having the width dimension.
Can be formed. For example, when joining with point A at point C shown in FIG.
In this case, the pipe body 10 having a larger diameter than the joint at the point B can be formed. In addition, if the point D is joined to the point A as shown in FIG. 15, the pipe body 10 having a larger diameter than in the case of FIG. 14 can be easily formed.

As described above, by changing the initial joining position of the element 2 at one end of the strip-shaped pipe member 1, the pipe main body 10 having a different width can be easily formed by one kind of the strip-shaped pipe member 1 having a width dimension. The width dimension of the strip-shaped pipe member 1 may be only one type. In addition, when forming the pipe main body 10 as shown in FIG. 14 and FIG.
Fastener-shaped joining means is a preferred example.

(Sixth Embodiment) FIG. 16 shows a well-known fastener opened and tightened state.
The end of the strip-shaped pipe material 1 is distorted in the lateral direction in accordance with opening and closing by the sliding operation of the slider 6. In the case of the band-shaped pipe member 1 made of synthetic resin and capable of being bent, it is possible to open and close the end portion of the band-shaped pipe member 1 by absorbing the distortion by this bending force. However, when the strip-shaped pipe member 1 is made of a thin metal plate having elasticity,
Lateral strain cannot be absorbed. Therefore,
When the strip-shaped pipe member 1 is made of a metal plate, an element 2 having a shape as shown in FIG. 17 is used.

That is, when the strip-shaped pipe material 1 is rolled into a cylindrical shape, one end of the strip-shaped pipe material 1 moves upward from below, and the other end moves downward from above.
The end surfaces of both ends of the strip-shaped pipe member 1 face each other. Therefore, as shown in FIG. 17, the element 2 at the end of the strip-shaped pipe material 1 is formed to be bent at substantially 90 degrees, and both ends of the strip-shaped pipe material 1 move up and down, thereby joining both ends of the strip-shaped pipe material 1. I'm trying. In this case, the groove of the slider 6 for meshing the opposing element 2 is adapted to the structure of the element 2. Therefore, in the synthetic resin band-shaped pipe material 1, joining can be performed by moving both ends in the left-right direction, and in the metal band-shaped pipe material 1, joining can be performed by moving the end portion in the vertical direction. Become. FIG. 18 shows a case where the pipe main body 10 is formed as described above. There is a slight level difference in the portion of the element 2, but there is no problem when used for piping such as wiring.

(Seventh Embodiment) In each of the above embodiments, a plurality of types of strip-shaped pipe members 1 are prepared and used in the longitudinal direction. In this embodiment, The length of the long pipe body 10 can be freely formed. The pipe body 10 is formed from the strip-shaped pipe material 1, cut at an arbitrary location, and the joined portions at both ends of the pipe body 10 at the cut location are shown in FIGS.
This is fixed by a stopper 30 as shown in FIG.

The stopper 30 is formed in a substantially U-shape, and is provided with a projection 31 having a pointed tip from the upper and lower pieces. The projection 31 is formed of a synthetic resin strip pipe. The joint portion is prevented from coming off by cutting into the joint portion at the end of the pipe body 10 formed of the material 1. Therefore, the slider 6 is slid by a necessary length as a pipe, and the pipe body 1 having a desired size is slid.
0 is formed, and the strip-shaped pipe material 1 is cut at a position where the slider 6 comes to a desired size. Both ends of the pipe body 10 after cutting are fixed with the stoppers 30. The slider 6 is mounted on the element 2 side of the remaining strip-shaped pipe material 1.

The stopper 30 is, as shown in FIG.
The clamp body 30 is clamped from above and below so as to extend over both ends of the pipe body 10 and the stopper 30 is caulked with a tool such as pliers. Both ends of the pipe body 10 are fixed by the stoppers 30 so that the elements 2 do not come off from each other.

When the pipe body 10 is further formed from the remaining strip-shaped pipe material 1, the slider 6 is slid while the other element 2 is inserted into the slider 6 of the strip-shaped pipe material 1. Then, the stopper 30 is attached to both ends of the strip-shaped pipe material 1 at the end of the formed pipe body 10.
Is fixed so that the elements 2 do not come off from each other. Then, the slider 6 is slid in the same manner as described above to form the pipe main body 10 of a required size. The processing of the end portion is performed by the stopper 30 in the same manner as described above.

In this embodiment, a considerably long strip-shaped pipe material 1 is formed, wound around a jig like an electric cord reel, and a pipe body 10 of a required length can be continuously and easily formed. Can be.

At the end of the strip-shaped pipe material 1, the lower stopper 7 is formed in the previous example, but only the element 2 is formed without forming the lower stopper 7, and the slider 6 is used. After the elements 2 at both ends are engaged with each other, the end processing may be performed by the stopper 30. When the end of the pipe body 10 is fixed by the stopper 30, a hole is formed at a position where the projection 31 bites, and the stopper 3 is fixed.
The fixing of 0 may be made easier. In such a case, it is possible to prevent the projection 31 from breaking the strip-shaped pipe member 1 when the stopper 30 is crimped.

The method of joining both ends of the strip-shaped pipe material 1 by the stopper 30 can be applied to the case where the strip-shaped pipe material 1 is made of synthetic resin in each of the above embodiments.

In the embodiments other than those shown in FIGS. 14 and 15, a scale is provided along the longitudinal direction of the lower surface of the band-shaped pipe member 1 (the outer peripheral surface when the pipe body 10 is formed). Thus, it can also be used as a scale, and in particular, when used for piping under the floor, the length of the pipe body 10 piped under the floor can always be confirmed. Therefore, it is possible to easily visually recognize how long the pipe body 10 that is being formed and piped is now in length.
