Abstract

PROBLEM TO BE SOLVED: To provide an auxiliary tool not using any belt for fixing a hose to a unit and preventing the hose from being dropped from the unit even if an inner pressure acts against the hose to extend straight.SOLUTION: A rigid cylinder 5 having a thickness to enable a hose to be inserted and uniformly curved in one direction over its entire length is formed with an opening part 6 over its entire length in a vertical direction with respect to the bending direction.EFFECT: Since the curved rigid cylinder is formed with an opening part in a direction perpendicular to its bending direction, even if an inner pressure acts against a hose inserted into the cylinder and the hose is tried to extend straight, a force directed toward the opening part of the cylinder does not work against the hose and the hose is not pulled out of the cylinder.SELECTED DRAWING: Figure 2

Description

本発明はホースの曲がり補助具に関するものであって、特に消防用ホースや排水ホースなどのように扁平に折り畳まれたホースを、キンクすることなくスムーズに曲げることができる補助具に関するものである。   The present invention relates to a bending aid for a hose, and particularly to an auxiliary tool that can smoothly bend a hose folded flat, such as a fire hose or a drainage hose, without kinking.

従来この種の曲がり補助具としては、実願平２−１２５０６１号出願（実開平４‐８２４９３号）のマイクロフィルムや、実用新案登録第３１３１７３９号公報などに記載されたものが知られている。   Conventionally, as this type of bending aid, those described in Japanese Patent Application No. Hei 2-1225061 (Japanese Utility Model Publication No. Hei 4-82493), Utility Model Registration No. 3131739, and the like are known.

これらのものは、ホースを挿通し得る太さの管を約９０度程度に曲げ、その曲がりの外側彎曲面にスリットを形成したものであって、当該スリットからホースを管内に挿入するようにしたものである。   These are made by bending a tube that can pass through a hose to about 90 degrees and forming a slit in the outer curved surface of the bend. The hose is inserted into the tube through the slit. Is.

しかしながらこのものでは、管内に挿通されたホース内に水を送入し、ホースに内圧がかかると、ホースが真っ直ぐに延びようとするため、前記スリットを押し拡げてホースが管から押し出されることがある。   However, in this case, when water is fed into the hose inserted in the pipe and the internal pressure is applied to the hose, the hose tends to extend straight, so that the slit is expanded and the hose is pushed out of the pipe. is there.

また実用新案登録第３０６６０５０号公報には、ホースを挿通し得る管を９０度乃至１８０度屈曲し、その屈曲方向に対して垂直方向にスリットを形成したものが記載されているが、かかる構造ではこの中に挿通されたホースが急角度で屈曲されるため、器具の中でキンクしてしまう可能性が高い。   In addition, Japanese Utility Model Registration No. 3066050 discloses that a tube through which a hose can be inserted is bent 90 degrees to 180 degrees, and a slit is formed in a direction perpendicular to the bending direction. Since the hose inserted in this is bent at a steep angle, there is a high possibility that the hose will be kinked in the instrument.

また建設マネジメント技術２００９年５月号６０〜６６ページには、図４に示すように、ホース１を曲げたときの曲がりの内側部分及び外側部分に沿うサポート板２に、ホース１をベルト３で括りつけるようにしたものが記載されている。   In addition, as shown in FIG. 4, the May 2009 issue pages 60-66 of the construction management technology include a belt 3 for the hose 1 on the support plate 2 along the inner and outer portions of the bend when the hose 1 is bent. It describes what was tied up.

しかしながらこのものではサポート板２にホース１を取り付ける手間がかかる。しかも
ホース１に消防用ホースなどのように大きな内圧が作用したときには、ホース１が直線状に延びようとするため、それをサポート板２に固定し続けることが困難となることも起こり得る。 However, in this case, it takes time to attach the hose 1 to the support plate 2. In addition, when a large internal pressure such as a fire hose acts on the hose 1, the hose 1 tends to extend linearly, and it may be difficult to keep it fixed to the support plate 2.

本発明はかかる事情に鑑みなされたものであって、ホースを器具に取り付けるためにベルトなどを使用することがなく、且つホースに内圧が作用して真っ直ぐに延びようとした場合においても、ホースが器具から脱落するようなことがないようにすることを目的とするものである。   The present invention has been made in view of such circumstances, and even when a belt is not used to attach the hose to the instrument, and the internal pressure acts on the hose and the hose is intended to extend straight, The purpose is to prevent the tool from falling off.

而して本発明は、ホースを挿通し得る太さを有し、その全長に亙って一方向に均一に曲がった剛直な筒体の、当該曲がり方向に対して垂直方向に、その全長に亙って開口部を形成したことを特徴とするものである。   Thus, the present invention has a thickness that allows the hose to be inserted, and the rigid cylinder that is bent uniformly in one direction over its entire length has a length that is perpendicular to the bending direction. In other words, the opening is formed.

本発明のホースの曲がり補助具においては、前記筒体が、１５〜６０度曲がっていることが好ましい。また前記筒体の曲率半径が、筒体の口径の５〜１５倍であることが好ましい。また前記開口部が、筒体の周長の５〜３０％であることが好ましい。また前記開口部の反対面には、脚を設けることが好ましい。   In the bending aid for a hose of the present invention, it is preferable that the cylindrical body bends 15 to 60 degrees. Moreover, it is preferable that the curvature radius of the said cylinder is 5 to 15 times the diameter of a cylinder. Moreover, it is preferable that the said opening part is 5 to 30% of the circumference of a cylinder. Moreover, it is preferable to provide a leg on the opposite surface of the opening.

本発明によれば、剛直な筒体内に前記開口部からホースを挿入するので、そのホースを筒体に取り付けるために、ベルトなどの特別な手段を必要とせず、またホースに内圧がかかっていても扁平であっても、ホースは筒体により保持されるので、何ら問題なく使用することができる。   According to the present invention, since the hose is inserted into the rigid cylinder from the opening, no special means such as a belt is required to attach the hose to the cylinder, and internal pressure is applied to the hose. Even if it is flat, the hose is held by the cylinder, so that it can be used without any problem.

また本発明は、曲がった剛直な筒体の、その曲がり方向に対して垂直方向に開口部を形成しているので、その筒体内に挿通したホースに内圧が作用し、ホースが真っ直ぐに延びようとした場合においても、ホースには筒体の開口部に向かう力が作用することはなく、ホースが筒体から抜け出すことがない。   In the present invention, since the bent rigid cylinder is formed with an opening in a direction perpendicular to the bending direction, an internal pressure acts on the hose inserted in the cylinder so that the hose extends straight. Even in this case, a force toward the opening of the cylinder does not act on the hose, and the hose does not come out of the cylinder.

以下本発明を図面に基づいて説明する。図１及び図２は本発明のホースの曲がり補助具４を示すものであって、図１はその平面図であり、図２は横断面図である。   The present invention will be described below with reference to the drawings. 1 and 2 show a hose bending aid 4 of the present invention, FIG. 1 is a plan view thereof, and FIG. 2 is a cross-sectional view thereof.

当該曲がり補助具４はホース１を挿通し得る太さを有する筒体５であって、当該筒体５はＦＲＰなどの剛直な材料よりなっている。そしてその全長に亙って一方向に均一に曲がっており、当該曲がり方向に対して垂直方向に、その全長に亙って開口部６が形成されている。   The bending assisting tool 4 is a cylinder 5 having a thickness that allows the hose 1 to be inserted, and the cylinder 5 is made of a rigid material such as FRP. And it bends uniformly in one direction over the full length, and the opening part 6 is formed over the full length in the direction perpendicular | vertical to the said bending direction.

そして当該曲がり補助具４の開口部６からホース１を筒体５内に挿入する。例えば高い位置と低い位置との間にホース１を敷設する場合には、高い位置の端部においてホース１が局部的に当たり、また低い位置からホース１が立ち上がる個所においてホース１が地面に擦れる。   Then, the hose 1 is inserted into the cylindrical body 5 from the opening 6 of the bending aid 4. For example, when the hose 1 is laid between a high position and a low position, the hose 1 hits locally at the end of the high position, and the hose 1 rubs against the ground at a place where the hose 1 rises from the low position.

そこで図３に示すようにかかるホース１が局部的に当たったり地面に擦れたりする箇所に本発明の曲がり補助具４を取り付けることにより、ホース１の損傷を有効に防止することができる。   Therefore, as shown in FIG. 3, the hose 1 can be effectively prevented from being damaged by attaching the bending aid 4 of the present invention to a location where the hose 1 hits locally or rubs against the ground.

そして当該筒体５の曲がり角度αは、１５〜６０度曲がっていることが適当である。また当該筒体５の曲がりの曲率半径Ｒは、筒体５の口径の５〜１５倍程度とするのが適当である。   And it is appropriate for the bending angle (alpha) of the said cylinder 5 to be bent 15-60 degree | times. Further, it is appropriate that the curvature radius R of the bending of the cylindrical body 5 is about 5 to 15 times the diameter of the cylindrical body 5.

前記特許文献１乃至３に記載されたものにおいては、管を９０度又はそれ以上に屈曲せしめられており、且つ曲率半径Ｒは筒体の口径の１〜３倍程度であるので、ホース１が器具の内部でキンクする可能性があるが、本発明によれば、ホース１が曲がり補助具４内でキンクすることはない。   In those described in Patent Documents 1 to 3, the tube is bent 90 degrees or more, and the radius of curvature R is about 1 to 3 times the diameter of the cylinder. Although there is a possibility of kinking inside the instrument, according to the present invention, the hose 1 is not bent and kinked in the auxiliary tool 4.

ホース１を６０度以上に曲げる必要があるときは、本発明の曲がり補助具４を若干間隔を開けてホースに複数取り付けることにより、キンクすることなく大きい範囲で曲げることが可能である。   When it is necessary to bend the hose 1 to 60 degrees or more, it is possible to bend it in a large range without kinking by attaching a plurality of the bending aids 4 of the present invention to the hose with a slight gap.

また本発明における開口部６の大きさは、筒体５の周長の５〜３０％が適当である。５％あれば当該開口部６を通してホース１を筒体５内に挿入することが可能であり、３０％以下であればホース１が筒体５から脱落することはない。   Further, the size of the opening 6 in the present invention is suitably 5 to 30% of the circumferential length of the cylinder 5. If it is 5%, it is possible to insert the hose 1 into the cylinder 5 through the opening 6, and if it is 30% or less, the hose 1 will not fall out of the cylinder 5.

また本発明においては、図２に示すように、前記開口部６の反対面に脚７を設けることが好ましい。本発明の曲がり補助具４を地面の上で水平方向にホース１を曲げるために使用することもでき、その場合には前記脚７で曲がり補助具４を支えることにより、曲がり補助具４が転がることなく安定してホース１を誘導することができる。   In the present invention, as shown in FIG. 2, it is preferable to provide a leg 7 on the opposite surface of the opening 6. The bending aid 4 of the present invention can be used to bend the hose 1 horizontally on the ground. In this case, the bending aid 4 rolls by supporting the bending aid 4 with the legs 7. The hose 1 can be guided stably without any problems.

前記脚７は、曲がり補助具４の全長に亙って連続して設けることが好ましいが、断続的に設けることも可能である。   The legs 7 are preferably provided continuously over the entire length of the bending aid 4, but can also be provided intermittently.
