Description

本発明は、建物の床や天井や垂直な壁面などに沿って配管固定される可撓性と耐圧性に優れた配管ホースに関する。
詳しくは、ホース本体に光遮断層を有する配管ホースに関する。
The present invention relates to a piping hose excellent in flexibility and pressure resistance that is fixed along a floor or ceiling of a building or a vertical wall surface.
Specifically, the present invention relates to a piping hose having a light blocking layer on the hose body.

従来、この種の配管ホースとして、黒色の光遮断層の表面及びその内面を白色の色透過防止層で覆った内層と、この内層を被覆する外層とからなり、上記内側の色透過防止層には、抗菌剤やシリコンなどの滑材を混入し、上記外側の色透過防止層の表面には、ポリエステル系の補強糸を巻きつけ、その外側を透明な素材に着色をした外層で覆ってなる防藻ホースがある(例えば、特許文献1参照)。   Conventionally, this kind of piping hose is composed of an inner layer in which the surface and inner surface of a black light blocking layer are covered with a white color transmission preventing layer, and an outer layer covering the inner layer. Is mixed with a lubricant such as antibacterial agent or silicone, and the outer color permeation preventive layer surface is wrapped with a polyester-based reinforcing thread, and the outside is covered with a transparent outer colored layer. There is an anti-algae hose (see, for example, Patent Document 1).

特開平7−55070号公報(第2−3頁、図1)JP-A-7-55070 (page 2-3, FIG. 1)

しかし乍ら、このような従来の配管ホースでは、太陽光の透過による藻の発生や雑菌などの発生が防止できるものの、光遮断層でホース全周が覆われるため、建物の床や天井や垂直な壁面などに沿って配管固定した後は、ホースの外からホース内の流れ状況が確認できないから、流体などの詰まり箇所を容易に検出できず、詰まりが発生した場合には、ホース全長に亘って交換する必要があって、コスト高になるという問題があった。   However, such conventional piping hoses can prevent the generation of algae and germs due to the transmission of sunlight, but the entire circumference of the hose is covered with a light shielding layer. After fixing the pipe along the wall, etc., the flow status inside the hose cannot be confirmed from the outside of the hose, so it is not easy to detect clogged parts such as fluids. There was a problem that it was necessary to replace it and the cost was high.

本発明のうち第一の発明は、太陽光の透過による障害を防止しながらホース内の流れ状況を確認することを目的としたものである。
第二の発明は、第一の発明の目的に加えて、透視窓の視界を遮ることなくホース軸方向への伸びを防止することを目的としたものである。
第三の発明は、第一の発明または第二の発明の目的に加えて、流体が溜まらないようにホースの曲がりをコントロールすることを目的としたものである。
第四の発明は、第一の発明、第二の発明または第三の発明の目的に加えて、ホース内の流れ状況を視覚でより明確に確認することを目的としたものである。
The first invention of the present invention is intended to confirm the flow situation in the hose while preventing a failure due to the transmission of sunlight.
In addition to the object of the first invention, the second invention is intended to prevent the hose from extending in the axial direction without blocking the view of the transparent window.
In addition to the object of the first invention or the second invention, the third invention aims to control the bending of the hose so that the fluid does not accumulate.
In addition to the objects of the first invention, the second invention, or the third invention, the fourth invention aims to more clearly confirm the flow situation in the hose visually.

前述した目的を達成するために、本発明のうち第一の発明は、ホース本体に光遮断層を設け、この光遮断層の周方向一部に、ホース本体の軸方向へ延びる透視窓を開設したことを特徴とするものである。
第二の発明は、第一の発明の構成に、前記透視窓を除く光遮断層の配置部分に、ホース本体の軸方向へ延びる縦糸をホース本体の軸方向全長に亘って設けた構成を加えたことを特徴とする。
第三の発明は、第一の発明または第二の発明の構成に、前記ホース本体の透視窓を挟んで対向する位置に、ホース本体の軸方向へ延びる複数本の縦糸を設けた構成を加えたことを特徴とする。
第四の発明は、第一の発明、第二の発明または第三の発明の構成に、前記ホース本体に、流体の流れ方向を示す表示部を設けた構成を加えたことを特徴とする。
In order to achieve the above-described object, the first invention of the present invention is to provide a light blocking layer on the hose body, and to open a transparent window extending in the axial direction of the hose body in a part of the light blocking layer in the circumferential direction.

The warp does not enter the viewing window.
Accordingly, it is possible to prevent the hose from extending in the axial direction without blocking the view of the see-through window.
As a result, piping can be fixed over a long period of time.

第三の発明は、第一の発明または第二の発明の効果に加えて、ホース本体の透視窓を挟んで対向する位置に、ホース本体の軸方向へ延びる複数本の縦糸を設けることにより、透視窓を挟んで対向するように配置された複数本の縦糸が互いに突っ張り合うため、透視窓からホース本体の中心へ向かう透視方向へはホース本体が屈曲し易いが、この透視方向と交差(直交)する光遮断方向へはホース本体が屈曲し難くて、直進性の高い配管が可能となり利便性が高まる。
従って、流体が溜まらないようにホースの曲がりをコントロールすることができる。
In addition to the effects of the first invention or the second invention, the third invention provides a plurality of warp yarns extending in the axial direction of the hose body at a position facing the transparent window of the hose body, A plurality of warps arranged so as to face each other across the fluoroscopic window stick to each other. ), The hose body is difficult to bend in the light blocking direction, and piping with high straightness is possible, increasing convenience.

従って、ホース内の流れ状況を視覚でより明確に確認することができる。
In the fourth invention, in addition to the effects of the first invention, the second invention or the third invention, the hose body is provided with a display portion indicating the flow direction of the fluid, so that it can be seen through the see-through window. The possible flow situation in the hose can be easily estimated based on the display unit.
Therefore, the flow state in the hose can be visually confirmed more clearly.

本発明の実施形態は、図1〜図4に示す如く、ホース本体Aが可撓性材料からなる内層A1及び外層A2と、これらの間に補強糸や補強繊維などを螺旋状に巻き付けることで形成される補強層A3とからなり、この外層A2全体又はその少なくとも表面部分のみか或いは他の部分に光遮断層1を設けると共に、この光遮断層1の周方向一部には、該ホース本体Aの軸方向へ延びる透視窓2を開設することにより、ホース内を目視可能にしている。   In the embodiment of the present invention, as shown in FIGS. 1 to 4, the hose body A has an inner layer A <b> 1 and an outer layer A <b> 2 made of a flexible material, and a reinforcing thread or a reinforcing fiber is wound spirally between them. The light blocking layer 1 is provided on the entire outer layer A2, at least the surface portion of the outer layer A2, or on other portions of the outer layer A2, and a portion of the light blocking layer 1 in the circumferential direction includes the hose body. By opening a see-through window 2 extending in the axial direction of A, the inside of the hose is visible.

上記内層A1及び外層A2は、例えば塩化ビニル又はポリエチレンやポリプロピレンなどのオレフィン樹脂又はフッ素樹脂などからなる軟質合成樹脂系の材料、又はシリコーンゴムなどのゴム系材料、又はこれら材料の組み合わせを夫々単層に形成するか、或いは複数の層を一体的に積層させることで形成している。   The inner layer A1 and the outer layer A2 are made of, for example, a soft synthetic resin material made of olefin resin or fluorine resin such as vinyl chloride or polyethylene or polypropylene, a rubber material such as silicone rubber, or a combination of these materials. Or by laminating a plurality of layers integrally.

なお、内層A1又は外層A2がある場合には、図示せぬが必要に応じて上記内層A1の内側に、ホース内を通る流体に合わせた透明材料からなる最内層A4を設けたり、上記外層A2の外側に保護用の透明材料からなる最外層(図示せず)を設けることも可能である。   When there is an inner layer A1 or an outer layer A2, although not shown, an innermost layer A4 made of a transparent material adapted to the fluid passing through the inside of the hose is provided inside the inner layer A1 as necessary, or the outer layer A2 It is also possible to provide an outermost layer (not shown) made of a transparent transparent material for protection on the outside.

このようなホース本体Aの製造方法としては、押し出し成形装置によって、先ず内層A1を押出成形した後に、その外周面に沿って補強層A3の補強糸又は補強繊維などを巻き付け、その外側に外層A2を押出成形して積層することで一体化される。   As a method of manufacturing such a hose body A, first, the inner layer A1 is extruded by an extrusion molding device, and then the reinforcing yarn or the reinforcing fiber of the reinforcing layer A3 is wound along the outer peripheral surface thereof, and the outer layer A2 is wound outside thereof. Are integrated by extruding and laminating.

上記補強層A3の補強糸又は補強繊維としては、例えばポリエステルやナイロンやアラミド繊維か又は細いモノフィラメント(monofilament:単繊維)を編んだマルチフィラメントなどが使用され、これを上記内層A1の外周面に沿って螺旋状に巻き付けて網状にするか、或いはニット編みなどで筒状に編み込むことにより、耐圧性能の向上を図っている。   As the reinforcing yarn or reinforcing fiber of the reinforcing layer A3, for example, polyester, nylon, aramid fiber, or a multifilament knitted with a thin monofilament (monofilament) is used, and this is along the outer peripheral surface of the inner layer A1. Thus, the pressure resistance is improved by wrapping in a spiral shape to form a net, or knitting into a cylindrical shape by knitting.

更に、上記補強層A3として、例えばステンレスなどの金属線や太いモノフィラメント(延伸モノフィラメント)などの硬質合成樹脂製の線材か又はそれらの組み合わせを螺旋状に巻き付けることにより、潰れ難くして保形性能の向上を図ることも可能である。   Furthermore, as the reinforcing layer A3, for example, a metal wire such as stainless steel, a hard synthetic resin wire material such as a thick monofilament (stretched monofilament) or a combination thereof is spirally wound, so that it is difficult to be crushed and has a shape retaining performance. It is also possible to improve.

また、上記光遮断層1は、図2(a)(b)に示す如く、上記外層A2の周方向一部を除いた略全体を、例えば黒色などの太陽光が透過し難い色の材料で構成することにより形成され、この周方向一部と上記内層A1からなるそれ以外の部分を透明又は半透明の材料で構成するか、或いは図3(a)(b)に示す如く、上記外層A2の周方向一部を除いた表面部分のみを、例えば黒色などの太陽光が透過し難い色の材料で被覆することにより形成され、この周方向一部を含む外層A2の略全体と上記内層A1からなるそれ以外の部分を透明又は半透明の材料で構成している。   Further, as shown in FIGS. 2 (a) and 2 (b), the light blocking layer 1 is made of a material having a color that hardly allows sunlight to pass through, for example, substantially the entire outer layer A2 except for a part in the circumferential direction. The outer layer A2 may be formed by forming a part of the circumferential direction and the other part of the inner layer A1 with a transparent or translucent material, or as shown in FIGS. 3 (a) and 3 (b). Only the surface portion excluding a part in the circumferential direction is covered with a material of a color such as black that does not easily transmit sunlight, and substantially the entire outer layer A2 including a part in the circumferential direction and the inner layer A1. The other part which consists of consists of a transparent or translucent material.

そして、上記透視窓2は、図2(a)及び図3(a)に示す如く、上記ホース本体Aの周方向一部のみに開設されるか、又は図2(b)及び図3(b)に示す如く、上記ホース本体Aの周方向へ適宜間隔ごとに二つ夫々径方向へ一直線上に開設されるか、或いは図示せぬが上記ホース本体Aの周方向へ適宜間隔ごとに三つ以上開設される。   The see-through window 2 is opened only in a part of the hose body A in the circumferential direction as shown in FIGS. 2 (a) and 3 (a), or FIGS. 2 (b) and 3 (b). As shown in FIG. 2, two hose bodies A are provided on the straight line in the radial direction at every appropriate interval in the circumferential direction of the hose body A, or three at an appropriate interval in the circumferential direction of the hose body A. Opened above.

このように製造されたホース本体Aは、配管ホースとして建物の床や天井などに沿って横方向へ配管固定されるか、又は壁面に沿って縦方向へ配管固定されるか、或いは傾斜するように配管固定されて使用する。   The hose body A manufactured in this way is fixed in the horizontal direction along the floor or ceiling of the building as a piping hose, or fixed in the vertical direction along the wall surface, or inclined. Use with the pipe fixed.

一方、上記ホース本体Aには、流体の流れ方向を示す表示部(図示せず)を設けることが好ましい。
この表示部としては、例えば矢印などが用いられ、外層A2の表面部分や透視窓2の表面に、例えば印刷などで形成することが最も容易である。
以下、本発明の各実施例を図面に基づいて説明する。
On the other hand, the hose body A is preferably provided with a display portion (not shown) indicating the fluid flow direction.
As this display portion, for example, an arrow or the like is used, and it is most easily formed on the surface portion of the outer layer A2 or the surface of the transparent window 2 by, for example, printing.
Embodiments of the present invention will be described below with reference to the drawings.

この実施例1は、図1〜図3に示す如く、前記ホース本体Aの全周に亘って、ポリエステルやナイロンやアラミド繊維などの補強糸又は補強繊維からなるブレード3を、網状に巻き付けるか又はニット編みなどで筒状に編み込むと共に、前記透視窓2を除く光遮断層1の配置部分に、ホース本体Aの軸方向へ延びる縦糸4を、該ホース本体Aの軸方向全長に亘って設けることにより、前記補強層A3が形成されるものである。   In Example 1, as shown in FIGS. 1 to 3, a braid 3 made of reinforcing yarn or reinforcing fiber such as polyester, nylon, or aramid fiber is wound around the entire circumference of the hose body A in a net shape or While knitting in a cylindrical shape by knitting or the like, warp yarns 4 extending in the axial direction of the hose body A are provided over the entire axial length of the hose body A in the arrangement portion of the light blocking layer 1 excluding the transparent window 2. Thus, the reinforcing layer A3 is formed.

上記縦糸4は、上記ブレード3と同じポリエステルやナイロンやアラミド繊維又は細いモノフィラメントを編んだマルチフィラメントなどの伸び難い材料からなり、上記内層A1の外周面に沿って周方向へ適宜間隔毎に複数本埋設される。   The warp 4 is made of a material that is difficult to stretch, such as the same polyester as the blade 3, nylon, aramid fiber, or multifilament knitted with a thin monofilament, and a plurality of warp yarns are provided at appropriate intervals in the circumferential direction along the outer peripheral surface of the inner layer A <b> 1. Buried.

更に、上記縦糸4は、ホース本体Aの透視窓2を挟んで対向する位置(図面では上下)に、夫々複数本ずつ等間隔毎に配置することが好ましい。
また、上記光遮断層1で覆われる部分を硬い材料で成形し、透視窓2を柔らかい材料で成形することが好ましい。
Furthermore, it is preferable that a plurality of the warp threads 4 are arranged at equal intervals, respectively, at positions facing each other across the see-through window 2 of the hose body A (up and down in the drawing).
Moreover, it is preferable to shape | mold the part covered with the said light shielding layer 1 with a hard material, and shape | mold the transparent window 2 with a soft material.

次に、斯かる配管ホースの作用効果について説明する。
ホース本体Aの透視窓2が、建物の床や天井などに沿って略水平となるように配管固定した場合には、該ホース本体Aの上部に配置された光遮断層1を介して太陽光がホース内へ入り込まないと共に、該ホース本体Aの上下中間部に配置された透視窓2を介してホースの外からホース内が目視可能になる。
Next, the effect of such a piping hose is demonstrated.
When the see-through window 2 of the hose body A is piped and fixed so as to be substantially horizontal along the floor or ceiling of the building, sunlight is transmitted through the light blocking layer 1 disposed on the upper portion of the hose body A. While not entering the hose, the inside of the hose can be seen from the outside of the hose through the see-through window 2 arranged in the upper and lower middle part of the hose body A.

それにより、太陽光の紫外線などでホース内の流体が劣化したり、藻やバクテリアなどの雑菌の発生を防止できると共に、透視窓2からホース内における流体の流れ状況や色の変化(劣化具合)を確認できる。   As a result, it is possible to prevent the fluid in the hose from being deteriorated by ultraviolet rays of sunlight, etc., and to prevent generation of germs such as algae and bacteria, and the flow status and color change in the hose from the fluoroscopic window 2 (deterioration condition) Can be confirmed.

特に、図2(a)及び図3(a)に示す如く、透視窓2をホース本体Aの周方向一部のみに開設した場合には、ホース内が目視し難くなるものの、光遮断性に優れて藻やバクテリアなどの雑菌が更に発生し難くなる。
また、図2(b)及び図3(b)に示す如く、透視窓2をホース本体Aの周方向へ適宜間隔ごとに二つ夫々径方向へ一直線上に開設した場合には、光遮断性に若干低下する虞があるものの、ホースの反対側まで目視できるから流体の色など微細な部分までよく見える。
In particular, as shown in FIGS. 2 (a) and 3 (a), when the transparent window 2 is opened only in a part in the circumferential direction of the hose body A, the inside of the hose becomes difficult to see, but the light blocking property is improved. Excellent bacteria and bacteria such as algae are less likely to occur.
Further, as shown in FIGS. 2 (b) and 3 (b), when the see-through windows 2 are opened in a straight line in the radial direction at appropriate intervals in the circumferential direction of the hose body A, the light shielding property is obtained. However, it is possible to see the other side of the hose so that fine parts such as the color of the fluid can be seen well.

更に、実施例1では、透視窓2を除く光遮断層1の配置部分に縦糸4がホース本体Aの軸方向全長に亘って設けられるため、該縦糸4で透視窓2の視界が遮られることがなく、ホース内が目視し易いと共に、ホース本体Aのホース軸方向への伸びを防止できる。   Furthermore, in Example 1, the warp yarn 4 is provided over the entire length in the axial direction of the hose body A in the arrangement portion of the light blocking layer 1 excluding the see-through window 2, so that the view of the see-through window 2 is blocked by the warp yarn 4. In addition, the inside of the hose can be easily seen, and the hose body A can be prevented from extending in the hose axial direction.

そして、透視窓2を挟んで上下対向する位置に複数本の縦糸4が設けられる場合には、上下の縦糸4が互いに突っ張り合うため、透視窓2からホース本体Aの中心へ向かう略水平な透視方向へはホース本体Aが屈曲し易いが、この透視方向と交差(直交)する上下方向へはホース本体Aが屈曲し難い。
それにより、直進性の高い配管が可能となって、ホースの一部が上下に垂れ難くなるので、ホースの中に流体が溜まることがない。
When a plurality of warp yarns 4 are provided at positions vertically opposite to each other with the see-through window 2 interposed therebetween, the upper and lower warp yarns 4 stick to each other, so that the substantially horizontal see-through from the see-through window 2 toward the center of the hose body A is achieved. The hose body A is easy to bend in the direction, but the hose body A is difficult to bend in the vertical direction intersecting (orthogonal) with the see-through direction.
Thereby, piping with high linearity is possible, and part of the hose is difficult to hang up and down, so that fluid does not accumulate in the hose.

また、上記縦糸4に代えて光遮断層1で覆われる部分を硬い材料で成形し、透視窓2を柔らかい材料で成形するか、又は上記縦糸4に加えて光遮断層1で覆われる部分を硬い材料で成形し、透視窓2を柔らかい材料で成形した場合にも、上下の硬い光遮断層1が互いに突っ張り合うため、透視窓2からホース本体Aの中心へ向かう略水平な透視方向へはホース本体Aが屈曲し易いが、この透視方向と交差(直交)する上下方向へはホース本体Aが屈曲し難い。
それにより、直進性の高い配管が可能となって、ホースの一部が上下に垂れ難くなるので、ホースの中に流体が溜まることがない。
Further, the portion covered with the light blocking layer 1 instead of the warp yarn 4 is molded with a hard material, and the transparent window 2 is formed with a soft material, or the portion covered with the light blocking layer 1 in addition to the warp yarn 4 is formed. Even when the transparent window 2 is formed of a hard material and the transparent window 2 is formed of a soft material, since the upper and lower hard light blocking layers 1 stick to each other, the substantially horizontal transparent direction from the transparent window 2 toward the center of the hose body A is Although the hose body A is easy to bend, the hose body A is difficult to bend in the vertical direction intersecting (orthogonal) with the perspective direction.
Thereby, piping with high linearity is possible, and part of the hose is difficult to hang up and down, so that fluid does not accumulate in the hose.

この実施例2は、図4に示す如く、前記補強層A3の補強糸又は補強繊維として、ポリエステルやナイロンやアラミド繊維などの補強糸又は補強繊維からなるブレード3aを、網状に巻き付けるか又はニット編みなどで筒状に編み込むと共に、ステンレスなどの金属線や太いモノフィラメント(延伸モノフィラメント)などの硬質合成樹脂製の線材からなるコイル3bを螺旋状に巻き付けた構成が、前記図1〜図3に示した実施例1とは異なり、それ以外の構成は図1〜図3に示した実施例1と同じものである。   In Example 2, as shown in FIG. 4, a braid 3a made of reinforcing yarn or reinforcing fiber such as polyester, nylon, or aramid fiber is wound as a reinforcing yarn or reinforcing fiber of the reinforcing layer A3, or is knitted. A configuration in which a coil 3b made of a hard synthetic resin wire material such as a metal wire such as stainless steel or a thick monofilament (stretched monofilament) is spirally wound as shown in FIGS. Unlike the first embodiment, the other configuration is the same as that of the first embodiment shown in FIGS.

図示例の場合には、前記縦糸4の代わりにコイル3bを巻き付けているが、ブレード3aとコイル3bと縦糸4を全て埋設することも可能である。   In the case of the illustrated example, the coil 3b is wound instead of the warp 4 but the blade 3a, the coil 3b, and the warp 4 can all be embedded.

従って、図4に示す実施例2も上述した実施例1と同様な作用効果が得られ、更に加えて硬質材料からなるコイル3bを巻き付けたので、ホースが潰れ難くなって保形性能が向上するという利点がある。   Therefore, the second embodiment shown in FIG. 4 also has the same effect as the first embodiment described above, and additionally the coil 3b made of a hard material is wound, so that the hose is not easily crushed and the shape retaining performance is improved.
