Description

本発明は、液体が循環することで身体を冷やすことのできるもの、例えば、冷却服、帽子、ヘルメット等に適用される実用的な身体の冷却技術に関する。 The present invention relates to a practical body cooling technique applied to, for example, cooling clothes, hats, helmets, etc., which can cool the body by circulating a liquid.

従来から、身体を循環する液体で冷却する冷却服が各種提案されている。
例えば、本出願人は特許文献1において、身体の動きによって液体路が折れ、液体路が流れないことを防止するために液体路内にメッシュ等を固定した液体路部材を提案している。
上記特許文献1に係る発明は、極めて実用的な冷却服等を提供できる技術である。
Conventionally, various cooling clothes that cool with a liquid circulating in the body have been proposed.
For example, in Patent Document 1, the applicant proposes a liquid passage member in which a mesh or the like is fixed in the liquid passage in order to prevent the liquid passage from breaking due to the movement of the body and preventing the liquid passage from flowing.
The invention according to Patent Document 1 is a technique capable of providing extremely practical cooling clothes and the like.

国際公開(WO2016013353)International release (WO2016013353)

本発明者は、実用的な冷却服等を開発している過程において、人体の頭のような曲率半径の大きな部分や、動きの大きい箇所、例えば両手や肘などの身体部分を良好に冷却できるにはどのような構成が必要であるかを誠意、探求し続けてきた。
しかしながら、実際には曲率の大きな面に実用的で快適な冷却用の液体路部材を発明することは難しかった。
In the process of developing practical cooling clothes, the present inventor can satisfactorily cool a part having a large radius of curvature such as the head of the human body and a part having a large movement, for example, a body part such as both hands and elbows. We have been sincerely exploring what kind of configuration is necessary for the product.
However, in reality, it has been difficult to invent a practical and comfortable liquid path member for cooling on a surface having a large curvature.

一方、シリコンチューブのような柔らかい円管を冷却服に取り付ける構成に比べて、複数の接合シートを融着することによって略平面形で帯形に延びる液体路(以下、略平面形帯形液体路と称する)を形成した方が液体の流れる面の接触面積を大きくでき、冷却効果を大きくすることができることを把握している。
このような略平面形帯形の液体路を身体面に沿わせる場合において、本発明者が誠意努力したことによって気が付いた具体的な課題は以下の通りである。
(A)頭部などの曲率の大きな身体面に略平面形帯形液体路をどのように取り付ければいいのか?ということがある。例えば、面ファスナーを用いて布部に取り付ける構成では、面ファスナーの取付け工程が増えるとともに追従性が悪くなり、着心地が悪くなるという課題がある。
(B)一方、略平面形帯形液体路を製造時に簡単に布部に固定することができ、製造コストを抑えることが望まれている。
(C)さらに、略平面形帯形液体路を取り付けた布部から簡単に着脱自在にできる構成が望まれる。その理由の一つは、略平面形帯形液体路が破損した場合等にその破損部分だけを取り替えることがコスト的に有利であることによる。
(D)面ファスナーを設けることで、身体に接する布部の上に面ファスナーを介して略平面形帯形液体路が存在することになるので、身体に接する布部よりも離れた位置に略平面形帯形液体路にあることになり、冷却性が低下する課題がある。
(E)暑い季節にヘルメットを被って作業することは、頭部が高温になり、作業者にとって厳しい環境になる。また、頭部が高温になると思考力や判断力が低下して重大な人身事故を招くことが各種の文献で報告されている。この課題に対して、ヘルメット内に空隙を作り、外部の空気をヘルメット内に導くことによってヘルメット内の温度を下げることも提案されているが、外部空気が自然にヘルメット内に入るオートバイ用ヘルメット以外のヘルメットにおいては、その効果は低い。
さらに、本質的なことは、従来、水冷式冷却部材を頭に装着した状態で、ヘルメットを被るという発想は全くなかった。その理由は、ヘルメットと頭部の狭い隙間の空間に配置できるような薄い水冷式冷却部材を構成することは不可能であると全ての当業者が考えていたからである。
本発明は、ヘルメットの安全性を低下させることなく、水冷式頭部フードを頭部に装着しても、通常のヘルメットと頭部の間に形成される狭い空間においても水冷式頭部フードを問題なく配置できる薄型の身体冷却用の液体路部材を提供することを技術課題の一つとする。
本発明の目的は、上記従来技術の各課題を解決することができる液体路部材とその製造方法を提供することにある。
なお、上記に記載した以外の発明の課題、その解決手段及びその効果は、後述する明細書内の記載において詳しく説明する。
On the other hand, as compared with the configuration in which a soft circular tube such as a silicon tube is attached to the cooling clothes, a liquid path extending into a strip shape in a substantially flat shape by fusing a plurality of bonding sheets (hereinafter referred to as a substantially flat strip liquid path). It is understood that the contact area of the surface on which the liquid flows can be increased and the cooling effect can be increased by forming (referred to as).
The specific problems that the present inventor has noticed through his sincere efforts in making such a substantially flat band-shaped liquid passage along the body surface are as follows.
(A) How should a substantially flat band-shaped liquid passage be attached to a body surface having a large curvature such as the head? There is that. For example, in the configuration in which the surface fastener is attached to the cloth portion, there is a problem that the number of attachment steps of the surface fastener is increased, the followability is deteriorated, and the wearing comfort is deteriorated.
(B) On the other hand, it is desired that the substantially flat strip-shaped liquid passage can be easily fixed to the cloth portion at the time of manufacturing, and the manufacturing cost can be suppressed.
(C) Further, a configuration that can be easily attached to and detached from the cloth portion to which the substantially flat strip-shaped liquid passage is attached is desired. One of the reasons is that it is cost-effective to replace only the damaged part when the substantially flat band-shaped liquid passage is damaged.
(D) By providing the hook-and-loop fastener, a substantially flat band-shaped liquid path exists on the cloth portion in contact with the body via the surface fastener, so that the liquid passage is substantially separated from the cloth portion in contact with the body. Since it is in a flat band-shaped liquid path, there is a problem that the cooling property is lowered.
(E) Working with a helmet in the hot season causes the head to become hot, which creates a harsh environment for the worker. In addition, it has been reported in various documents that when the temperature of the head becomes high, thinking ability and judgment ability deteriorate and cause serious personal injury. To solve this problem, it has been proposed to create a gap inside the helmet and guide the outside air into the helmet to lower the temperature inside the helmet, but other than motorcycle helmets where the outside air naturally enters the helmet. The effect is low in the helmet of.
Furthermore, what is essential is that, in the past, there was no idea of wearing a helmet with a water-cooled cooling member attached to the head. The reason is that all those skilled in the art thought that it was impossible to construct a thin water-cooled cooling member that could be placed in the narrow space between the helmet and the head.
INDUSTRIAL APPLICABILITY The present invention provides a water-cooled head hood even when the water-cooled head hood is attached to the head without deteriorating the safety of the helmet, even in a narrow space formed between a normal helmet and the head. One of the technical issues is to provide a thin liquid passage member for body cooling that can be arranged without any problem.
An object of the present invention is to provide a liquid path member and a method for manufacturing the same, which can solve the above-mentioned problems of the prior art.
The problems of the inventions other than those described above, the means for solving the problems, and the effects thereof will be described in detail in the description described later.

本発明は多面的に表現できるが、例えば、代表的なものを挙げると、次のように構成したものである。なお、下記各発明において、各符号は後述する実施形態との対応関係を分かりやすくするために一例として示したものであり、本発明の各構成要素は、実施形態に記載した符号に係る構成に限定されないことは言うまでもない。 The present invention can be expressed in many ways, but for example, a typical one is configured as follows. In each of the following inventions, each reference numeral is shown as an example in order to make it easier to understand the correspondence with the embodiment described later, and each component of the present invention has a configuration related to the reference numeral described in the embodiment. It goes without saying that it is not limited.

本発明に係る身体冷却用の液体路部材1は、少なくとも2枚の接合シート4を接合することによって形成され、2次元的広がりを有する略平面形帯形蛇行パターンとして形成された液体が循環する蛇行形液体路3と、
少なくとも2枚の布部で構成され、曲率が大きな頭部等の身体面を覆う3次元的布部に形成される布部係止部28とから構成され、
前記布部係止部28は前記蛇行形液体路3の蛇行形状と略相似形の係止ガイド部34と、前記蛇行形液体路3を前記布部係止部28から出し入れできる開口部33とを有し、
さらに前記蛇行形液体路3を、前記3次元的布部に形成された前記布部係止部28に対応した略平面展開図となるように形成したことを特徴とする(請求項1)。
なお、前記係止ガイド部の略相似形の意味は、蛇行形液体路の全体形状としての略相似形という意味ではなく、蛇行形液体路が布部係止部に係止される場合に、その係止の要点となる線分又は点群が前記略相似形に形成されているという意味である。
この構成であれば、略平面形帯形の蛇行形液体路を布部係止部に係止できるので、身体の動きにかかわらず、蛇行形液体路を身体に沿うように保持でき、冷却性を維持できる。また、開口部から蛇行形液体路を布部係止部から出し入れできるので、製造時に製造しやくなるとともに、部分的な破損時に交換等も簡単に行える。
さらに、着脱自在にするための面ファスナーを必要としないので、液体路部材の厚さを薄く構成できるとともに、身体の冷却性能を高めることができ、かつ着心地を良くすることができる。
なお、本来、「2次元的広がりである平面蛇行パターンとして形成された蛇行形液体路」は3次元的な凹凸を有する曲面には対応できない。しかし、本発明の構成であれば、蛇行形液体路を「3次元的布部に対応した略平面展開図となる」構成を採用することで、布部係止部において接触面積を増やして冷却性能を向上できる利点がある。

With this configuration, the meandering liquid path having a substantially flat band shape can be locked to the cloth portion locking portion, so that the meandering liquid path can be held along the body regardless of the movement of the body, and the cooling property can be improved. Can be maintained. Further, since the meandering liquid path can be taken in and out from the cloth portion locking portion from the opening, it can be easily manufactured at the time of manufacturing and can be easily replaced at the time of partial damage.
Further, since a hook-and-loop fastener is not required to make the liquid path member removable, the thickness of the liquid path member can be made thin, the cooling performance of the body can be improved, and the comfort can be improved.
Originally, "a meandering liquid path formed as a plane meandering pattern that is a two-dimensional spread" cannot correspond to a curved surface having three-dimensional unevenness.

[第1実施形態]
以下、図1~図9に示す本発明に係る第1実施形態について、図面に基づき説明する。
まず、本実施形態の前提となる蛇行形液体路3について説明する。
図1に示すように、蛇行形液体路3は複数の接合シート4・4を接合することで液体路3が構成されている。
この蛇行形液体路3は、複数の接合シート4・4の外縁部及び内縁部(図面上で左側及び右側、又は上側及び下側)を接合して縁部接合部7・7を作る。また、中心領域である液体路3となる領域を接合せずに帯形の液体通路を残すことによって図1及び図3に示すような所定形状パターンの蛇行形液体路3が形成される。
但し、図3は、蛇行形液体路3は縁部接合部7・7の幅を記載せず簡素化して描いている。
[First Embodiment]
Hereinafter, the first embodiment according to the present invention shown in FIGS. 1 to 9 will be described with reference to the drawings.
First, the meandering liquid passage 3 which is the premise of this embodiment will be described.
As shown in FIG. 1, the meandering liquid path 3 is formed by joining a plurality of joining sheets 4 and 4.
In this meandering liquid passage 3, the outer edge portions and inner edge portions (left side and right side, upper side and lower side in the drawing) of the plurality of joint sheets 4 and 4 are joined to form the edge joint portion 7 and 7. Further, by leaving a band-shaped liquid passage without joining the region to be the liquid passage 3 which is the central region, the meandering liquid passage 3 having a predetermined shape pattern as shown in FIGS. 1 and 3 is formed.
However, in FIG. 3, the meandering liquid path 3 is drawn in a simplified manner without describing the width of the edge joint portion 7.7.

本実施形態における蛇行とは、曲面部の液体路3が例えば、上下方向に伸びている場合は、左右方向に振れて広がっているような略平面形状の帯形の曲面部がある意味である。
図1に示す構成では、入口部43と出口部44の横幅D1と蛇行部36の最大幅D2とが同じ横幅を有している構成(D1=D2)が示してある。曲率が大きな身体の部分であれば、図1に示す構成(D1=D2)では、その曲率が大きな身体の部分に横幅のある帯形液体路3を良好に接触することは容易でないと言える。この点については、後で図3~図6を参照しつつ、説明する。
なお、本実施形態の基本的概念は、3次元の最終的な製品である身体覆い部材に2次元の帯形蛇行液体路3を沿わせることができるように構成した点である。具体的には、平面形状である蛇行液体路3を3次元凹凸形状に対応した2次元展開図として形成されている点である。
The meandering in the present embodiment means that, for example, when the liquid path 3 of the curved surface portion extends in the vertical direction, there is a substantially planar band-shaped curved surface portion that swings and spreads in the left-right direction. ..
In the configuration shown in FIG. 1, a configuration (D1 = D2) in which the width D1 of the inlet portion 43 and the outlet portion 44 and the maximum width D2 of the meandering portion 36 have the same width is shown. If the body part has a large curvature, it can be said that it is not easy to make good contact with the wide band-shaped liquid passage 3 with the body part having a large curvature in the configuration (D1 = D2) shown in FIG. This point will be described later with reference to FIGS. 3 to 6.
The basic concept of the present embodiment is that the two-dimensional band-shaped meandering liquid path 3 can be aligned with the body covering member, which is the final three-dimensional product. Specifically, it is a point that the meandering liquid path 3 having a planar shape is formed as a two-dimensional developed view corresponding to a three-dimensional uneven shape.

また、蛇行形液体路3の縁部接合部7・7を構成する場合に、上側接合シート4と下側接合シート4を構成する素材として合成樹脂を使用し、熱融着によって蛇行形液体路3を形成してある。
さらに、蛇行形液体路3が折れ曲がって液体が流れないことの不都合を解決するために、図1に示すように、立体構造体5を蛇行形液体路3内に収容している。立体構造体5は身体からみて上下方向Yに幅を有して柔軟性を有するメッシュのような物体である。立体構造体5には液体が流れる隙間を有する物体である。
このような立体構造体5を有する構成であれば、蛇行形液体路3が屈曲したときであっても、立体構造体5の存在によって冷却液体の流れる空間を確保することができる。図1に示す構成ではメッシュ6を蛇行形液体路3の延びる方向の中心線に沿って1本だけ配置するように構成してある。立体構造体5の本数を1本に限定することで、液体路3の液体の流通性、循環性を向上できることが多いことを本発明者は確認している。
Further, when forming the edge joints 7 and 7 of the meandering liquid path 3, a synthetic resin is used as a material for forming the upper joining sheet 4 and the lower joining sheet 4, and the meandering liquid path is heat-sealed. 3 is formed.
Further, in order to solve the inconvenience that the meandering liquid passage 3 is bent and the liquid does not flow, the three-dimensional structure 5 is housed in the meandering liquid passage 3 as shown in FIG. The three-dimensional structure 5 is a mesh-like object having a width in the vertical direction Y and having flexibility when viewed from the body. The three-dimensional structure 5 is an object having a gap through which a liquid flows.
With such a configuration having the three-dimensional structure 5, even when the meandering liquid path 3 is bent, the space through which the cooling liquid flows can be secured by the presence of the three-dimensional structure 5. In the configuration shown in FIG. 1, only one mesh 6 is arranged along the center line in the extending direction of the meandering liquid passage 3. The present inventor has confirmed that by limiting the number of the three-dimensional structure 5 to one, the flowability and circulation of the liquid in the liquid passage 3 can often be improved.

また、図1に示すように、接合口具6としてのスパウト6は、幅広の熱融着シート4を融着するための接合面部8と、接合面部8を貫くように管部11が設けられた管取付部9とを有している。接合面部8の形状は四角形形、半円形状など各種の形状が採用できるが、いずれの構成も熱融着シート4を液体が漏れないようにしっかり密閉する水平方向Xに広がりを持った領域面を備えている。
図1に示す構成では、接合口具6としてのスパウト6は、液体路3の内側に臨む位置に設けられた管口10が設けてあり、その管口10によって蛇行形液体路3と連通されている。
Further, as shown in FIG. 1, the spout 6 as the joint opening tool 6 is provided with a joint surface portion 8 for fusing a wide heat-sealing sheet 4 and a pipe portion 11 so as to penetrate the joint surface portion 8. It has a pipe mounting portion 9. Various shapes such as a quadrangular shape and a semicircular shape can be adopted as the shape of the joint surface portion 8, but in any of the configurations, the heat-sealed sheet 4 is tightly sealed so that the liquid does not leak. It is equipped with.
In the configuration shown in FIG. 1, the spout 6 as the joint opening tool 6 is provided with a pipe opening 10 provided at a position facing the inside of the liquid passage 3, and is communicated with the meandering liquid passage 3 by the pipe opening 10. ing.

接合面部8から突出した管部11の周囲には、管部11から外周側に拡径するように突出する先細形状部12が形成してある。この先細形状部12は、スパウト6に連結する接続管、例えば液体供給管、液体戻り管、連結管等の各種接続管をワンタッチで取付け、抜けることを抑制する構造にするための構成である。先細形状部12としては、略円錐形(略タケノコ形状とも言える)、略球形、略楕円球形などの各種の構成が採用できる。
このような先細形状部12を有する管取付部9を採用することで、雄ねじと雌ねじの螺合結合のように、通常の液体容器に採用されるスパウトの構成に比べて着脱の処理を簡便化することができる。この構成は液体路部材を構成する一部の蛇行形液体路3が破損した場合にその部分だけを交換する場合に有利となる。
スパウト6は、接合シート4と接合しやすい同じ種類系統の合成樹脂、例えばPE、PVC等で構成してある。好ましくは同一の合成樹脂材で構成する。同一の合成樹脂材であれば、熱融着に必要な条件、例えば、溶ける温度等が同じであり、接合が良好になるからである。
A tapered portion 12 projecting from the pipe portion 11 to the outer peripheral side is formed around the pipe portion 11 protruding from the joint surface portion 8. The tapered portion 12 has a structure for attaching various connecting pipes connected to the spout 6, such as a liquid supply pipe, a liquid return pipe, and a connecting pipe, with one touch and preventing them from coming off. As the tapered portion 12, various configurations such as a substantially conical shape (which can also be said to be a substantially bamboo shoot shape), a substantially spherical shape, and a substantially elliptical spherical shape can be adopted.
By adopting the pipe mounting portion 9 having such a tapered portion 12, the process of attachment / detachment is simplified as compared with the spout configuration adopted for a normal liquid container, such as the screw connection of a male screw and a female screw. can do. This configuration is advantageous when a part of the meandering liquid passage 3 constituting the liquid passage member is damaged and only the portion is replaced.
The spout 6 is made of a synthetic resin of the same type that can be easily bonded to the bonding sheet 4, such as PE and PVC. It is preferably composed of the same synthetic resin material. This is because if the same synthetic resin material is used, the conditions required for heat fusion, for example, the melting temperature and the like are the same, and the bonding becomes good.

この第1実施形態に係る液体路部材1では、図2(A)(B)に示すように取付布部30と基部布部31を有している。但し、取付布部30と基部布部31の区別は技術的・構成的な意味において厳密に区別することは難しい。一般的には、基部布部31は衣服などの形状を構成する基本となる布地に対応し、取付布部30は前記基本となる布地を覆う布地で構成される場合が多い。
例えば、一例を挙れば、基部布部31は頭部や肩部などの曲率の大きな箇所を構成するための身体型用の布部である。また、その基部布部31に被せ布としての取付布部30を重ねて、図1に示す接合線としての想定ガイド部29に沿って、図9に示すようなそれぞれの曲線となる各係止ガイド部34a~係止ガイド部34gを形成することで布部係止部28を形成する。
なお、図2及び図7~図9にS字形の蛇行形液体路3が形成された場合を一例と示している。その理由は、S字形であれば、左右に振れる蛇行部36を有する点において、蛇行の最も典型的な基本的単位と言えるので、その点においてS字形の蛇行形液体路3を示している。
なお、S字形の横幅や長さを変えて、複数形状のS字形を適宜、連結することで、図3及び図14に示すような蛇行形液体路3を形成することができる。
また、図2では平面として示しているが、基部布部31は型紙に沿って切り出し、通常は縫い合わせることによって、身体の所定部分、即ち図3~図5に示すような曲率の大きな面を覆う例えば、頭部フード40の形状に構成することになる。
The liquid path member 1 according to the first embodiment has a mounting cloth portion 30 and a base cloth portion 31 as shown in FIGS. 2A and 2B. However, it is difficult to strictly distinguish between the mounting cloth portion 30 and the base cloth portion 31 in the technical and structural sense. In general, the base cloth portion 31 corresponds to the basic cloth constituting the shape of clothes or the like, and the mounting cloth portion 30 is often composed of the cloth covering the basic cloth.
For example, for example, the base cloth portion 31 is a cloth portion for a body shape for forming a portion having a large curvature such as a head portion and a shoulder portion. Further, the mounting cloth portion 30 as a covering cloth is superposed on the base cloth portion 31, and each locking is formed into a curved line as shown in FIG. 9 along the assumed guide portion 29 as the joining line shown in FIG. The cloth portion locking portion 28 is formed by forming the guide portion 34a to the locking guide portion 34g.
Note that FIGS. 2 and 7 to 9 show an example of the case where the S-shaped meandering liquid passage 3 is formed. The reason is that if it is S-shaped, it can be said to be the most typical basic unit of meandering in that it has a meandering portion 36 that swings to the left and right, and in that respect, the S-shaped meandering liquid passage 3 is shown.
By appropriately connecting a plurality of S-shapes by changing the width and length of the S-shape, the meandering liquid passage 3 as shown in FIGS. 3 and 14 can be formed.
Further, although shown as a flat surface in FIG. 2, the base cloth portion 31 is cut out along the pattern and usually sewn to cover a predetermined part of the body, that is, a surface having a large curvature as shown in FIGS. 3 to 5. For example, it will be configured in the shape of the head hood 40.

図2では、想定ガイド部29を構成する固定曲線32は布を縫い合わせた縫合曲線32で構成した例が示してある。しかし、固定曲線32は接着剤や熱融着などの方法で形成することを除外するものではない。
また、布部係止部28は、図9に示すように、蛇行形液体路3の形状よりも若干大きな相似形の形状の略袋形体35としてある。ここで、「略」袋形体35と言う理由は、袋に開口部33が形成されている理由による。具体的に言うと、略楕円形の蛇行部36の内側に第1開口部33a、第2開口部33bが形成されており、略楕円形の蛇行部36の外側に第1係止ガイド部34a,第2係止ガイド部34bが形成してある。
FIG. 2 shows an example in which the fixed curve 32 constituting the assumed guide portion 29 is composed of a stitched curve 32 in which cloth is sewn together. However, the fixed curve 32 does not exclude the formation by a method such as an adhesive or heat fusion.
Further, as shown in FIG. 9, the cloth portion locking portion 28 is a substantially bag-shaped body 35 having a similar shape slightly larger than the shape of the meandering liquid passage 3. Here, the reason for the "abbreviated" bag-shaped body 35 is that the opening 33 is formed in the bag. Specifically, the first opening 33a and the second opening 33b are formed inside the substantially elliptical meandering portion 36, and the first locking guide portion 34a is formed outside the substantially elliptical meandering portion 36. , The second locking guide portion 34b is formed.

さらに、第1開口部33a、第2開口部33bが形成されている取付布部30(上面布部)にはスリット形の布部切開部47が形成されているので、観音開きのように取付布部30が開くので、蛇行形液体路3を出し入れしやすくなっている。
また、図9に示すように、本実施形態の係止ガイド部34をより詳細に説明すると、係止ガイド部34は、前記した第1係止ガイド部34a,第2係止ガイド部34b以外に、第3係止ガイド部34c,第4係止ガイド部34d,第5係止ガイド部34e,第6係止ガイド部34f,第7係止ガイド部34gを有している。
第3係止ガイド部34cは、蛇行部36の内側である第1開口部33a側であって、液体の流れにおいて一方側(図9において下側)の接続口具6aに近くに設けられた係止ガイド部34である。
第4係止ガイド部34dは、蛇行部36の外側である第1係止ガイド部34a側であって、液体の流れにおいて一方側(図9において下側)の接続口具6aを受け止める第4係止ガイド部34eに連設する係止ガイド部34である。
Further, since the slit-shaped cloth portion incision 47 is formed in the mounting cloth portion 30 (upper surface cloth portion) on which the first opening 33a and the second opening 33b are formed, the mounting cloth is formed like a double door. Since the portion 30 is opened, it is easy to put in and take out the serpentine liquid passage 3.
Further, as shown in FIG. 9, when the locking guide portion 34 of the present embodiment is described in more detail, the locking guide portion 34 is other than the first locking guide portion 34a and the second locking guide portion 34b described above. It has a third locking guide portion 34c, a fourth locking guide portion 34d, a fifth locking guide portion 34e, a sixth locking guide portion 34f, and a seventh locking guide portion 34g.
The third locking guide portion 34c is provided on the side of the first opening 33a inside the meandering portion 36 and near the connection port 6a on one side (lower side in FIG. 9) in the flow of liquid. The locking guide portion 34.
The fourth locking guide portion 34d is on the side of the first locking guide portion 34a, which is the outside of the meandering portion 36, and receives the connection port 6a on one side (lower side in FIG. 9) in the flow of liquid. It is a locking guide portion 34 connected to the locking guide portion 34e.

第5係止ガイド部34eは、第3係止ガイド部34cと第4係止ガイド部34dを繋ぐように設けられた端部ガイド部である。第5係止ガイド部34eには管取付部9が突出できる端部開口38aを設けている。
第6係止ガイド部34fは、内側の第2開口部33b側であって、液体の流れにおいて他方側(図9において上側)の接続口具6bに近くに設けられた係止ガイド部34である。
第7係止ガイド部34gは、第2係止ガイド部34bと第6係止ガイド部34fを繋ぐように設けられた端部ガイド部である。第1係止ガイド部34eには管取付部9が突出できる端部開口38bを設けている。
The fifth locking guide portion 34e is an end guide portion provided so as to connect the third locking guide portion 34c and the fourth locking guide portion 34d. The fifth locking guide portion 34e is provided with an end opening 38a from which the pipe mounting portion 9 can protrude.
The sixth locking guide portion 34f is a locking guide portion 34 provided on the inner second opening 33b side and close to the connection port 6b on the other side (upper side in FIG. 9) in the flow of liquid. be.
The seventh locking guide portion 34g is an end guide portion provided so as to connect the second locking guide portion 34b and the sixth locking guide portion 34f. The first locking guide portion 34e is provided with an end opening 38b from which the pipe mounting portion 9 can protrude.

ここで、第5係止ガイド部34eに設けられた端部開口38aから突出する管取付部9にシリコンチューブ等の接続管48aを取り付ける。これとともに、第7係止ガイド部34gに設けられた端部開口38bから突出する管部付部9にシリコンチューブ等の接続管48bを取り付けることによって、布部係止部28内の蛇行形液体路3の位置ズレを強力に抑制することができる。
その理由は、入口と出口において、管取付部9・9と接続管48a・48bが接続されることによって、蛇行形液体路3の幅広の接合面部8の左右角部がそれぞれ入口と出口において、第5係止ガイド部34e及び第7係止ガイド部34gにおいて受け止められることになるからである。つまり、上下左右方向に激しい身体の動きが行なわれた場合でも入口と出口の位置が規定されれば、蛇行部36を有する液体路3が布部係止部28内の所定位置を外れて移動することはありえないということを利用しているのである。
Here, a connecting pipe 48a such as a silicon tube is attached to the pipe mounting portion 9 protruding from the end opening 38a provided in the fifth locking guide portion 34e. At the same time, by attaching a connecting pipe 48b such as a silicon tube to the pipe portion 9 protruding from the end opening 38b provided in the seventh locking guide portion 34g, the meandering liquid in the cloth portion locking portion 28. The misalignment of the road 3 can be strongly suppressed.
The reason is that by connecting the pipe mounting portions 9 and 9 and the connecting pipes 48a and 48b at the inlet and the outlet, the left and right corners of the wide joint surface portion 8 of the meandering liquid passage 3 are at the inlet and the outlet, respectively. This is because it will be received by the fifth locking guide portion 34e and the seventh locking guide portion 34g. That is, even if the body moves violently in the vertical and horizontal directions, if the positions of the entrance and the exit are specified, the liquid passage 3 having the meandering portion 36 moves out of the predetermined position in the cloth portion locking portion 28. It takes advantage of the fact that it is impossible to do.

図3は本実施形態に係る蛇行形液体路3を頭部フード40に適用した場合を示している。
蛇行形液体路3の一部の蛇行形状は、図3に示す入口部43と出口部44の横幅D1よりも蛇行部36の最大幅D2が大きく形成された略先広形蛇行部46を有していることによって略平面形帯形が曲率の大きな身体部分に接触面積が大きくなるように構成してある。
図3に示すように、この工夫は、例示的に説明すると、例えば、顔の頬から頭部の頂点に向かう曲率の大きな部分に略平面形帯形液体路を追従させる場合に単位面積当たりにおいて、蛇行させれば直線形の液体路に比べて液体が流れる面積を増やすことができることは容易に理解できる。
但し、同じ蛇行形態であっても「略玉子形蛇行部、円形に近い略楕円形蛇行部等の形状」を採用し、「入口部43と出口部44の横幅D1よりも蛇行部の最大幅D2が大きく形成された略先広形蛇行部46を有している」構成を採用することで、さらに、曲率の大きな部分に略平面形帯形液体路を良好に追従させ、体表面の温度を冷却できることが多いのである。
FIG. 3 shows a case where the meandering liquid passage 3 according to the present embodiment is applied to the head hood 40.
A part of the meandering shape of the meandering liquid passage 3 has a substantially wide-pointed meandering portion 46 in which the maximum width D2 of the meandering portion 36 is formed larger than the lateral width D1 of the inlet portion 43 and the outlet portion 44 shown in FIG. By doing so, the substantially planar band shape is configured so that the contact area becomes large with the body part having a large curvature.
As shown in FIG. 3, this device is exemplified. For example, in the case of following a substantially flat band-shaped liquid path to a portion having a large curvature from the cheek of the face to the apex of the head, per unit area. It is easy to understand that the area through which the liquid flows can be increased by meandering compared to the linear liquid path.
However, even if the meandering form is the same, the "shape of a substantially egg-shaped meandering portion, a substantially elliptical meandering portion close to a circle, etc." is adopted, and the "maximum width of the meandering portion is larger than the width D1 of the inlet portion 43 and the outlet portion 44". By adopting the configuration of "having a substantially wide meandering portion 46 in which D2 is largely formed", the substantially flat band-shaped liquid path is made to follow well to the portion having a large curvature, and the temperature of the body surface is reached. Can often be cooled.

なお、略先広形蛇行部46の蛇行部の曲率は、縁部接合部7・7の外縁で計るのではなく、中央部に形成された実質的に液体の流れる流路の曲線で計測すべきである。
他に、図3の蛇行形液体路3の配置形態の特徴を記述すると、蛇行形液体路3が蛇行しつつ広がる方向(前記した配置する方向27)に対して略先広形蛇行部46が左右両側に形成されている。
The curvature of the meandering portion of the substantially wide-pointed meandering portion 46 is not measured at the outer edge of the edge joint portion 7.7, but is measured by the curve of the flow path through which the liquid substantially flows, which is formed in the central portion. Should be.
In addition, to describe the characteristics of the arrangement form of the meandering liquid passage 3 in FIG. 3, the meandering portion 46 having a substantially wide tip with respect to the direction in which the meandering liquid passage 3 meanders and spreads (the above-mentioned arrangement direction 27). It is formed on both the left and right sides.

本実施形態における作用について簡単に説明する。
[面ファスナーを省略することができる利点]
取付布部30と基部布部31の間に形成された係止ガイド部34内に蛇行形液体路3が略収容されることになるので、マジックテープ(登録商標)のような面ファスナーを設ける構成に比べて図1に示すY方向の液体路3の厚さを薄くできる。また、面ファスナーを設けること自体が装着性を劣化させることになるので、面ファスナーを省略することで着心地を良くすることができる。
また、伸縮性、通気性のある機能性のある布部を用いても面ファスナーを設けた部分はその機能性を発揮できないので、着心地が悪くなるが、本構成ではそのような部分がなくなる点においても利点がある。
また、本実施形態の構成であれば、2枚の布部30・31を縫付ける縫合曲線32において、縫合距離が増えるだけなので、個別に面ファスナーを設ける構成に比べて製造コストを大幅に低減することができる。また、布部係止部28は、蛇行形液体路3の略全面を覆う布部を備えているので、液体路3が流れる液体の温度が外部の温度によって高くなることを抑制できる。
The operation in this embodiment will be briefly described.

Since the meandering liquid passage 3 is substantially accommodated in the locking guide portion 34 formed between the mounting cloth portion 30 and the base cloth portion 31, a hook-and-loop fastener such as a magic tape (registered trademark) is provided. The thickness of the liquid passage 3 in the Y direction shown in FIG. 1 can be reduced as compared with the configuration. Further, since the provision of the hook-and-loop fastener itself deteriorates the wearability, the comfort can be improved by omitting the hook-and-loop fastener.
In addition, even if a functional cloth part with elasticity and breathability is used, the part provided with the hook-and-loop fastener cannot exhibit its functionality, which makes it uncomfortable to wear, but such a part disappears in this configuration. There is also an advantage in that.
Further, in the configuration of the present embodiment, since the stitching distance is only increased in the stitching curve 32 for sewing the two cloth portions 30 and 31, the manufacturing cost is significantly reduced as compared with the configuration in which the surface fasteners are individually provided. can do. Further, since the cloth portion locking portion 28 includes a cloth portion that covers substantially the entire surface of the meandering liquid passage 3, it is possible to prevent the temperature of the liquid flowing through the liquid passage 3 from increasing due to an external temperature.

[布部係止部28内に蛇行形液体路3を出し入れする場合の処理が簡単に行なえる利点]
図7に示すようにまず、最初に接続口具6bを第1開口部33aに入れて、第2開口部33bから出した状態にする。この状態から図8に示すように、接続口具6aを端部開口38aから出した状態にすることによって蛇行形液体路3の下側半部を布部係止部28内に収容することができる。そして、図8の状態から接続口具6bを端部開口38bから出して、図9に示すように布部係止部28内に蛇行形液体路3を収納した状態にする。
このように蛇行した液体路であっても布部係止部28内に収容することができ、第1係止ガイド部34a,第2係止ガイド部34bによって蛇行形液体路3の外側域蛇行部36a・36bをそれぞれ受け止めて、その収容位置を維持することができる。
また、前記したように、接続口具6aの管取付部9を端部開口38aから出して接続管48aに接続し、接続口具6bの管取付部9を端部開口38bから出して接続管48bに接続する構成を採用しているので安定性は高まる。
なお、先に接続口具6aの管取付部9を端部開口38aから出してから、後から接続口具6bを開口部33bに出した状態にしてから、接続口具6bの管取付部9を端部開口38bから出す手順も採用できる。
[Advantage that processing can be easily performed when the meandering liquid passage 3 is taken in and out of the cloth portion locking portion 28]
As shown in FIG. 7, first, the connection port 6b is put into the first opening 33a and brought out from the second opening 33b. From this state, as shown in FIG. 8, the lower half of the meandering liquid passage 3 can be accommodated in the cloth portion locking portion 28 by making the connection port 6a protrude from the end opening 38a. can. Then, from the state of FIG. 8, the connection port 6b is taken out from the end opening 38b, and the meandering liquid passage 3 is housed in the cloth portion locking portion 28 as shown in FIG.
Even the meandering liquid path can be accommodated in the cloth portion locking portion 28, and the outer region meandering of the meandering liquid path 3 by the first locking guide portion 34a and the second locking guide portion 34b. The portions 36a and 36b can be received and their accommodation positions can be maintained.
Further, as described above, the pipe mounting portion 9 of the connecting port 6a is pulled out from the end opening 38a and connected to the connecting pipe 48a, and the pipe mounting portion 9 of the connecting port 6b is pulled out from the end opening 38b to connect the connecting pipe. Since the configuration connected to 48b is adopted, the stability is improved.
It should be noted that the pipe attachment portion 9 of the connection port tool 6a is first pulled out from the end opening 38a, and then the connection port tool 6b is put out to the opening 33b, and then the tube attachment portion 9 of the connection port tool 6b is taken out. Can also be adopted from the procedure of pulling out from the end opening 38b.

収容状態から蛇行形液体路3を布部係止部28から外す工程の場合は、それぞれ前記した収容する動作を逆に行なえば、簡単にできる。
また、蛇行形液体路3のS字形を複数個設けた長い蛇行形液体路3でも同様に第n開口部33と第n係止ガイド部34を設ければ、同じように出し入れを簡単に行えることが理解できる。この場合、S字形の形状・大きさの異なるものを連結して、図3に示すような複雑な蛇行形液体路3を布部係止部28内に収容することができる。
このような構成であれば、頭部や肩部などの曲率が大きい曲面に帯形の平面液体路の接触面積を増やして、取り付けることができる。
In the case of the step of removing the meandering liquid passage 3 from the cloth portion locking portion 28 from the accommodating state, it can be easily performed by reversing the accommodating operations described above.
Further, even in the long meandering liquid passage 3 provided with a plurality of S-shapes of the meandering liquid passage 3, if the nth opening 33 and the nth locking guide portion 34 are provided in the same manner, it can be easily taken in and out in the same manner. Can be understood. In this case, the S-shaped objects having different shapes and sizes can be connected to accommodate the complicated meandering liquid passage 3 as shown in FIG. 3 in the cloth portion locking portion 28.
With such a configuration, it is possible to increase the contact area of the strip-shaped flat liquid path and attach it to a curved surface having a large curvature such as a head or a shoulder.

[2次元的な平面的な蛇行形液体路3を3次元的凹凸曲面に対応させる構成]
図5(A)(C)に示すように頭部の頭面22の立体形状に沿うように基部布部31が形成されており、その基部布部31上に略袋形の布部係止部28が形成されている。この布部係止部28内に収容される蛇行形液体路3は図5(B)に示すように頭面22の3次元立体形状に沿うような略2次元展開図になっているので、図5(C)に示すように、布部係止部28内の蛇行形液体路3の状態を頭面22に沿うように構成することができる。
これに対して、図6(B)に示すように頭部の頭面22の立体形状に対応しない、単純なU字形のような蛇行形液体路3を採用すると、図6(C)に示すように、布部係止部28内の蛇行形液体路3は、捻じれたり、頭面22から浮いたりする状態(例えば、図6(C)の状態)になって、良好な冷却性を得ることができなくなる。
本実施形態であれば、製造時の蛇行型液体路3を基部布部31への取付けコスト、故障時の蛇行型液体路3取替コストの削減を行なうことができるとともに、冷却性能を高く維持できる。
また、前記したように、従来の面ファスナーで基部布部に蛇行形液体路3を取り付ける構成に比べて、雄型・雌型の2つの取付け部材が不要になり、追従性が良く、薄く形成することができる。したがって、頭部にかぶっても、ヘルメット内に違和感なく、強力に冷却することができる。特に、暑い時期にヘルメットを被ることが必要な作業場所やオートバイの運転者に好適な冷却部材を提供できる。
[Structure in which a two-dimensional planar meandering liquid path 3 corresponds to a three-dimensional uneven curved surface]
As shown in FIGS. 5A and 5C, a base cloth portion 31 is formed along the three-dimensional shape of the head surface 22 of the head, and a substantially bag-shaped cloth portion is locked on the base cloth portion 31. The portion 28 is formed. As shown in FIG. 5B, the serpentine liquid path 3 housed in the cloth portion locking portion 28 is a substantially two-dimensional developed view that follows the three-dimensional three-dimensional shape of the head surface 22. As shown in FIG. 5C, the state of the serpentine liquid passage 3 in the cloth portion locking portion 28 can be configured to be along the head surface 22.
On the other hand, if a simple U-shaped meandering liquid path 3 that does not correspond to the three-dimensional shape of the head surface 22 of the head as shown in FIG. 6 (B) is adopted, it is shown in FIG. 6 (C). As described above, the meandering liquid passage 3 in the cloth portion locking portion 28 is in a state of being twisted or floating from the head surface 22 (for example, the state of FIG. 6C), and has good cooling performance. You won't be able to get it.
According to the present embodiment, it is possible to reduce the cost of attaching the meandering liquid passage 3 at the time of manufacturing to the base cloth portion 31 and the cost of replacing the meandering liquid passage 3 at the time of failure, and maintain high cooling performance. can.
Further, as described above, as compared with the conventional configuration in which the meandering liquid path 3 is attached to the base cloth portion by the conventional hook-and-loop fastener, two attachment members, a male type and a female type, are not required, and the followability is good and the formation is thin. can do. Therefore, even if it is worn on the head, it can be strongly cooled inside the helmet without any discomfort. In particular, it is possible to provide a cooling member suitable for a work place where a helmet needs to be worn in a hot season or a motorcycle driver.

[第2実施形態]
図10~図12に示す本発明に係る第2実施形態について、図面に基づき説明する。
図10に示すように、例えば、エンボス加工等で形成した、小さい凹凸15が形成された凹凸シート2を少なくとも1枚含んで複数枚のシートを重ね合わせ、その一部を平面的に離隔的に融着させて形成した融着部14と、前記融着部14の間において融着されずに形成された流路部16とを有し、液体路3を融着部14と流路部16とを平面的に広がりを持って配置し、さらに縁部接合部7・7を設けることによっても、前記した蛇行形液体路3を構成することもできる。
合成樹脂シートなどのシート自体を形成するときに予め凹凸を形成してよい。また、合成樹脂シートに対して各種の後処理で凹凸を形成してもよい
[Second Embodiment]
A second embodiment according to the present invention shown in FIGS. 10 to 12 will be described with reference to the drawings.
As shown in FIG. 10, for example, a plurality of sheets including at least one uneven sheet 2 having small unevenness 15 formed by embossing or the like are laminated, and a part thereof is separated in a plane. It has a fused portion 14 formed by fusion and a flow path portion 16 formed without being fused between the fused portions 14, and the liquid passage 3 is provided between the fused portion 14 and the flow path portion 16. The meandering liquid passage 3 can also be configured by arranging the above-mentioned with a spread in a plane and further providing the edge joint portions 7.7.
When forming the sheet itself such as a synthetic resin sheet, unevenness may be formed in advance. Further, unevenness may be formed on the synthetic resin sheet by various post-treatments.

前記凹凸シート2を少なくとも2枚重ね合わせて液体路3を構成することで帯形に延びる液体路部材1を構成することができる。この構成であれば、上側、下側のシートに凹凸が形成されているので、大きく折れ曲がった状態でも流路部16においても十分な空間を確保しやすくなる。
次に、前記したように、薄く構成でき、曲率の大きな部分にも冷却用の液体を流すことができる融着部14と流路部16を備えた液体路3の製造方法の一例について説明する。
身体冷却用の液体路部材1は、小さい凹凸が形成された凹凸シート2を少なくとも1枚含んで複数枚のシートを重ね合わせた平面形の導液部材である。上側シートと下側シートの両方が凹凸シート2・2であることが好ましいが、一方が平坦シート、他方が凹凸シートの構成も実用上、十分に採用できる。
By superimposing at least two of the uneven sheets 2 to form the liquid path 3, the liquid path member 1 extending in a strip shape can be configured. With this configuration, since the upper and lower sheets are formed with irregularities, it is easy to secure a sufficient space in the flow path portion 16 even in a greatly bent state.
Next, as described above, an example of a method for manufacturing a liquid passage 3 provided with a fusion splicer portion 14 and a flow path portion 16 capable of being thinly configured and allowing a cooling liquid to flow even in a portion having a large curvature will be described. ..
The liquid passage member 1 for cooling the body is a flat liquid guide member in which a plurality of sheets are stacked, including at least one uneven sheet 2 on which small irregularities are formed. It is preferable that both the upper sheet and the lower sheet are uneven sheets 2 and 2, but a structure in which one is a flat sheet and the other is an uneven sheet can be sufficiently adopted in practical use.

また、蛇行形液体路3は、平面的に広がるシートにおいて、その一部を平面的に離隔的に融着させて形成した融着部14と、融着部14の間において融着されずに凹凸15を残した状態で形成された流路部16とを有している。図10に示す流路部16が冷却用液体の流れる通路となる。液体路部材1の全体形状は、図10に示す蛇行形は一例であり、図3に示すような頭部形状に対応させることもできる。
なお、図10においては簡便のために液体路3の一部を切り出した状態で融着部14、流路部16、凹凸15の構成を説明しているが、実際は液体路3の全面に亘って融着部14、流路部16、凹凸15が形成されている。
液体路部材1を薄く形成して、冷却水量を減らして迅速に冷やすことや着心地を良くすることに重点を置く場合は、1mm~3mm程度に液体路部材1の厚さを薄く製造することも可能になる。その時の凹凸の高さ設定は、例えば一例を挙げれば、0.05mm~1mmにすることもできる。
Further, the meandering liquid path 3 is not fused between the fused portion 14 formed by fusing a part thereof in a planarly separated manner and the fused portion 14 in the sheet extending in a plane. It has a flow path portion 16 formed with the unevenness 15 left. The flow path portion 16 shown in FIG. 10 is a passage through which the cooling liquid flows. The overall shape of the liquid path member 1 is an example of the meandering shape shown in FIG. 10, and can correspond to the head shape as shown in FIG.
In FIG. 10, for the sake of convenience, the configuration of the fused portion 14, the flow path portion 16, and the unevenness 15 is described in a state where a part of the liquid passage 3 is cut out, but in reality, the entire surface of the liquid passage 3 is covered. The fused portion 14, the flow path portion 16, and the unevenness 15 are formed.
When the liquid path member 1 is formed thin and the emphasis is on reducing the amount of cooling water to cool quickly and improving the comfort, the thickness of the liquid path member 1 should be reduced to about 1 mm to 3 mm. Will also be possible. The height of the unevenness at that time can be set to 0.05 mm to 1 mm, for example, to give an example.

以下、小さい凹凸15が形成された凹凸シート2を少なくとも1枚含んで複数枚のシートを重ね合わせて本実施形態に係る液体路3を作る工程の一例について説明する。
まず、図11(A)(B)に示すように2枚の例えば合成樹脂で構成された平坦シート17・17を用意して、図11(C)(D)に示すようにエンボス加工などの方法によって凹凸シート2・2を得る。凹凸15の高さ、横幅は冷却服などに採用した場合、良好に液体が良好に流れる大きさであれば特に制限はない。一例を挙げれば、前記凹凸の高さHを0.05mm~10mmの範囲に構成し、さらに好ましくは高さHを0.5mm~5mmの範囲に構成することもできる。
また、横幅Wを0.05mm~10mmの範囲に構成し、さらに好ましくは横幅Wを0.5mm~5mmの範囲に構成することもできる。
次いで、図12(A)に示すように平面的に所定の融着パターンを有する融着部押圧型18で凹凸シート2・2を挟み込んで融着させる。
そして、図12(B)(C)に示すように平面的に離隔して配置された融着部14とその間に凹凸部15を有する流路部16を形成する。
Hereinafter, an example of a step of forming the liquid passage 3 according to the present embodiment will be described by stacking a plurality of sheets including at least one uneven sheet 2 on which the small unevenness 15 is formed.
First, as shown in FIGS. 11 (A) and 11 (B), two flat sheets 17 and 17 composed of, for example, synthetic resin are prepared, and as shown in FIGS. 11 (C) and 11 (D), embossing or the like is performed. Concavo-convex sheets 2 and 2 are obtained by the method. When the height and width of the unevenness 15 are used for cooling clothes or the like, there is no particular limitation as long as the liquid flows well. As an example, the height H of the unevenness may be configured in the range of 0.05 mm to 10 mm, and more preferably the height H may be configured in the range of 0.5 mm to 5 mm.
Further, the width W may be configured in the range of 0.05 mm to 10 mm, and more preferably the width W may be configured in the range of 0.5 mm to 5 mm.
Next, as shown in FIG. 12 (A), the concavo-convex sheet 2 and 2 are sandwiched and fused by the fusion portion pressing mold 18 having a predetermined fusion pattern in a plane.
Then, as shown in FIGS. 12 (B) and 12 (C), a fused portion 14 arranged so as to be separated in a plane and a flow path portion 16 having an uneven portion 15 between them are formed.

図10~図12に示す構成では融着部14の融着パターンは、縦方向及び横方向一定間隔で円形の融着部を配置した構成となっている。融着部14間の配置間隔は液体が流れて、良好に身体を冷却できる配置間隔の範囲であれば特に限定されない。
一般的には、融着部14の構成に関する考え方は、
(1)ポンプ等によって圧送された液体の流量を確保できて、十分な冷却ができるような大きさの面積がある流路部16に設定する、
(2)液体を所定圧力で流した際、液体の圧力又は身体の動きによって融着部14が剥離しない程度の大きさに設定する、
(3)縦方向、横方向、斜め方向などのできるだけ全方位方向に液体が流れるような融着部14の形状を設定する。
の3点を考慮しつつ、それらのバランスを取って設定される。概して言えば、円形、楕円、多角形を平面上に離隔的に配置した構成が上記2つの要望を満たすことが多いと予想される。
In the configurations shown in FIGS. 10 to 12, the fusion pattern of the fusion portion 14 has a configuration in which circular fusion portions are arranged at regular intervals in the vertical direction and the horizontal direction. The arrangement interval between the fused portions 14 is not particularly limited as long as it is within the arrangement interval in which the liquid can flow and the body can be cooled well.
Generally, the idea regarding the configuration of the fusion splicer 14 is
(1) Set in the flow path portion 16 having an area large enough to secure the flow rate of the liquid pumped by a pump or the like and to sufficiently cool the liquid.
(2) When the liquid is flowed at a predetermined pressure, the size is set so that the fused portion 14 does not peel off due to the pressure of the liquid or the movement of the body.
(3) The shape of the fused portion 14 is set so that the liquid flows in all directions as much as possible, such as in the vertical direction, the horizontal direction, and the diagonal direction.
While considering the three points of, it is set by balancing them. Generally speaking, it is expected that a configuration in which a circle, an ellipse, and a polygon are arranged separately on a plane often satisfies the above two requirements.

本実施形態の構成であれば、平面的に離隔的に融着箇所を設けることによって、液体に圧力をかけた状態でも液体路3の膨らみを抑制でき、身体に対する当接面積を増やすことができる。また、凹凸シート2で形成しているので、必要であれば薄く形成できるので着心地が良くなり、かつ冷却に要する水量を減らすことができる。単位面積に対する冷却水量を減らすことができるので即座に身体を冷やすことができる。また、平面的に離隔的に融着させて形成した融着部14を有しているので、横、縦、斜め方向においても液体の流路を確保できる利点がある。しかも、身体の動きに応じて液体路3が曲がっても小さい凹凸15によって流路部3が閉鎖されることが抑制される。また、小さい凹凸15が形成された凹凸シート2を作ること、及び融着部14を形成することは簡単に行えるので、製造コストを大幅に低減することができる。
特に、蛇行形液体路3の厚さをできるだけ薄くしたい液体路部材の用途であれば、この第2実施形態に係る蛇行形液体路3を採用する利点は大きいと言える。
According to the configuration of the present embodiment, by providing the fused portions in a plane and separated manner, the swelling of the liquid passage 3 can be suppressed even in a state where pressure is applied to the liquid, and the contact area with the body can be increased. .. Further, since it is formed of the concavo-convex sheet 2, it can be formed thin if necessary, so that it is comfortable to wear and the amount of water required for cooling can be reduced. Since the amount of cooling water per unit area can be reduced, the body can be cooled immediately. Further, since the fused portion 14 is formed by being fused in a plane and separatedly, there is an advantage that a flow path of the liquid can be secured even in the horizontal, vertical, and diagonal directions. Moreover, even if the liquid path 3 bends according to the movement of the body, it is suppressed that the flow path portion 3 is closed by the small unevenness 15. Further, since the uneven sheet 2 on which the small unevenness 15 is formed and the fused portion 14 can be easily formed, the manufacturing cost can be significantly reduced.
In particular, if the application is for a liquid passage member whose thickness of the meandering liquid passage 3 is desired to be as thin as possible, it can be said that the advantage of adopting the meandering liquid passage 3 according to the second embodiment is great.

[第3実施形態]
第1実施形態では開口部33を、縫合曲線32を設けないことで構成したが、図13に示すように、この第3実施形態では、開口部33を帯形の略袋形体35に布部切開部47として形成し、その布部切開部47から蛇行形液体路3を出し入れする構成に形成してある。布部切開部47は、身体に接する基部布部31に被せる取付布部30に矩形、円形等の開口としての布部切開部47が設けられている。
図13に示す構成では、布部係止部28の取付布部30に複数の布部切開部47を設けることで、複数個の離隔した布部筒部37が形成された例が示されている。
[Third Embodiment]
In the first embodiment, the opening 33 is configured by not providing the suture curve 32, but as shown in FIG. 13, in this third embodiment, the opening 33 is formed into a strip-shaped substantially bag-shaped body 35. It is formed as an incision portion 47, and is formed so as to allow a meandering liquid passage 3 to be taken in and out from the cloth portion incision portion 47. The cloth portion incision 47 is provided with a cloth portion incision 47 as an opening such as a rectangle or a circle in the mounting cloth portion 30 that covers the base cloth portion 31 in contact with the body.
In the configuration shown in FIG. 13, an example is shown in which a plurality of separated cloth portion cylinder portions 37 are formed by providing a plurality of cloth portion incisions 47 in the mounting cloth portion 30 of the cloth portion locking portion 28. There is.

[第4実施形態]
図4及び図14に示すように、この第4実施形態は、頭部フード40において開閉部材42と管部50の配置構成を工夫した実施形態である。
具体的な工夫点としては、頭部フード40の正面側の中央線位置(図示せず)に首部布部41を左右に2分割する線ファスナー42を設けるとともに、線ファスナー42の部分を首部布部41よりも下方に延ばした延長部23・23を設けた点がある。
前記首部布部41よりも下方に延ばした延長部23・23を設けることで、腰部に支持されることが多い冷却用液体容器に向けて管路50・50を外部物に引っかかったりなどすることなく、確実に冷却用液体容器に接続することができる利点がある。
また、延長部23・23において、線ファスナー42の左右にある延長部23・23に供給液の管路50と戻り液の管部50とを設けている点がある。
図14(A)に示すように、首部布部41の管部50を首部布部41の略下端域に設けてある。
また、頭部に対して左右対称形に蛇行形液体路3・3を配置した構成としてあり、頭部布部49の後頭部側からそれぞれの左右の蛇行形液体路3・3を略下端域の左右の管部50・50に接続した構成にしてある。
さらに、首部布部41の略下端域には布部で構成された管形収容布部21を設け、その管形収容布部21内に管部50・50を収容し、その管部50・50を前面に設けられた延長部23・23に引き出した点がある。
また、図4に示すように、管路50は頭部の背面側から作業者の前面側に向けて略S字形又は略U字形に湾曲して、管路収容布部21内に収容されているので、延長部23・23から出た管路50・50が引っ張られることがあっても、管路収容布部21によってその引っ張り力を受け止めることができる。したがって、図4・図14に示す接続口具6に前記引っ張り力が係って接続口部6・6から管路50・50が抜けることを強力に抑制することができる。
[Fourth Embodiment]
As shown in FIGS. 4 and 14, the fourth embodiment is an embodiment in which the opening / closing member 42 and the pipe portion 50 are arranged in the head hood 40.
As a specific point of ingenuity, a wire fastener 42 that divides the neck cloth portion 41 into two left and right is provided at the center line position (not shown) on the front side of the head hood 40, and the portion of the wire fastener 42 is the neck cloth. There is a point that the extension portions 23 and 23 extending below the portion 41 are provided.
By providing the extension portions 23 and 23 extending downward from the neck cloth portion 41, the pipe lines 50 and 50 may be caught by an external object toward the cooling liquid container that is often supported by the lumbar region. There is an advantage that it can be reliably connected to the cooling liquid container.
Further, in the extension portions 23 and 23, there is a point that the extension portions 23 and 23 on the left and right of the wire fastener 42 are provided with the supply liquid pipe line 50 and the return liquid pipe portion 50.
As shown in FIG. 14A, the pipe portion 50 of the neck cloth portion 41 is provided in a substantially lower end region of the neck cloth portion 41.
Further, the structure is such that the meandering liquid paths 3 and 3 are arranged symmetrically with respect to the head, and the left and right meandering liquid paths 3 and 3 are located in the substantially lower end region from the back of the head side of the head cloth portion 49. It is configured to be connected to the left and right pipes 50 and 50.
Further, a tube-shaped accommodating cloth portion 21 composed of a cloth portion is provided in a substantially lower end region of the neck cloth portion 41, and the tube portions 50 and 50 are accommodated in the tube-shaped accommodating cloth portion 21, and the tube portion 50. There is a point where the 50 is pulled out to the extension portions 23 and 23 provided on the front surface.
Further, as shown in FIG. 4, the pipeline 50 is curved in a substantially S-shape or a substantially U-shape from the back side of the head toward the front side of the worker, and is accommodated in the pipeline accommodating cloth portion 21. Therefore, even if the pipelines 50 and 50 coming out of the extension portions 23 and 23 are pulled, the pulling force can be received by the pipeline accommodating cloth portion 21. Therefore, it is possible to strongly prevent the conduits 50 and 50 from coming off from the connection ports 6 and 6 due to the pulling force applied to the connection port 6 shown in FIGS. 4 and 14.
