Description

本発明は高圧洗浄ホース用保護具に関するものであり、特に、高圧洗浄ホースを扱う作業員、及びその周辺への被災を防止するための高圧洗浄ホース用保護具に関するものである。   The present invention relates to a high pressure cleaning hose protector, and more particularly, to a worker handling a high pressure cleaning hose and a high pressure cleaning hose protector for preventing damage to the surrounding area.

周知のように、航空機や車両における車軸の洗浄、及び、工事現場の道路や建物等を洗浄する際、高圧水を噴射して洗浄をすることが行われている。また、熱交換器等でも洗浄銃を使用せずに、作業員が直に高圧ホースを掴んで洗浄作業を行う場合もある。そのような高圧水洗浄作業では、洗浄水は高圧（例えば３０ＭＰａ〜５０ＭＰａ）に圧縮された状態で高圧洗浄ホース内に送り込まれ、そのホース先端に取り付けたノズルから高圧水を洗浄対象に向けて噴射させ、洗浄を行っている。   As is well known, when washing an axle in an aircraft or a vehicle and washing a road, a building, or the like at a construction site, the washing is performed by jetting high-pressure water. In some cases, an operator may perform a cleaning operation by directly grasping a high-pressure hose without using a cleaning gun even in a heat exchanger or the like. In such a high-pressure water cleaning operation, the cleaning water is sent into the high-pressure cleaning hose while being compressed to a high pressure (for example, 30 MPa to 50 MPa), and the high-pressure water is sprayed from the nozzle attached to the tip of the hose toward the object to be cleaned. And cleaning.

したがって、高圧洗浄を行う高圧洗浄ホース内は高圧になっているので、その高圧洗浄ホース自体は高圧に耐え得る強度を持って形成されている（例えば、特許文献１参照）。しかしながら、高圧洗浄ホースの劣化や摩耗等によっては、作業中に、不意に高圧洗浄ホースの途中に孔が開く、あるいは破裂を起こして、高圧水が噴出するということも少なくない。   Therefore, since the inside of the high-pressure washing hose that performs high-pressure washing is at a high pressure, the high-pressure washing hose itself is formed with a strength that can withstand high pressure (see, for example, Patent Document 1). However, depending on the deterioration or wear of the high-pressure washing hose, it is not uncommon for the high-pressure water to be ejected unexpectedly during the operation due to the opening or rupture of the high-pressure washing hose.

特開平７−１７１９１９号公報Japanese Unexamined Patent Publication No. 7-171919

上述したように、高圧洗浄を行う作業では、作業中に高圧洗浄ホースの途中に孔が開く、あるいは高圧洗浄ホースが破裂を起こす等して、高圧水が噴出するということも少なくない。そして高圧水が噴出した場合、作業員が素手で直に高圧洗浄ホースを掴んで作業をしていたようなときには噴出した高圧水や高圧洗浄ホースの破片が飛散して、手や足、腹部等にケガをする事故の危険性があった。また、作業員がケガに至らないまでも、高圧洗浄ホースの破片が周囲に飛散して、近傍に存在する作業員以外の第三者を被災させるという事故の危険性もあった。   As described above, in high pressure cleaning operations, high pressure water is often ejected by opening a hole in the middle of the high pressure cleaning hose or causing the high pressure cleaning hose to rupture during the operation. When high-pressure water is ejected, if the worker is holding the high-pressure washing hose directly with his bare hands, the ejected high-pressure water or fragments of the high-pressure washing hose will scatter and hands, feet, abdomen, etc. There was a risk of injury. Moreover, even if the worker did not get hurt, there was a risk of accidents in which fragments of the high-pressure washing hose were scattered around and damaged third parties other than workers in the vicinity.

しかしながら、従来では、このような事故を積極的に防止するような手段は講じられていなかった。   However, conventionally, no measures have been taken to actively prevent such accidents.

そこで、本発明は上記問題点に鑑みなされたものであり、高圧洗浄ホースの破損等による周囲の被害を最小限に防止することができるようにした、高圧洗浄ホースの外周に装着する高圧洗浄ホース用保護具を提供することを目的としている。   Accordingly, the present invention has been made in view of the above-described problems, and is a high pressure cleaning hose that is attached to the outer periphery of a high pressure cleaning hose so that damage to the surroundings due to breakage or the like of the high pressure cleaning hose can be minimized. The purpose is to provide personal protective equipment.

本発明は、上記目的を達成するために提案されたものであり、請求項１に係る発明は、高圧洗浄ホースを掴んで高圧水により洗浄作業をすることが可能な柔軟性を有する前記高圧洗浄ホースから、噴射または噴出される前記高圧水を身体に受け障害を受けるのを防止するため、
内径が前記高圧洗浄ホースの外径よりも大きく、かつ前記高圧水の水圧に耐え得る耐圧強度の筒状の保護カバー体として、前記高圧洗浄ホースの外周に着脱可能に装着される、高圧洗浄ホース用保護カバー体であって、補強繊維材料とシート状の樹脂材料とより構成され、
前記高圧洗浄ホース用保護カバー体は、シームレス状の円筒形に成形した前記補強繊維材料を樹脂射出成形型にセットされ、該樹脂射出成形型内で、前記樹脂材料を射出して成形され、前記補強繊維材料の一面側または両面（表面と裏面）側に前記樹脂材料が設けられ、
前記補強繊維材料は、ガラス繊維、金属繊維、ポリプロピレン繊維、ポリエチレン繊維、ポリアリレート繊維の材料より構成され、前記樹脂材料は、ナイロン、ポリエチレン、ポリスチレンの材料より構成される、ことを特徴とする。 The present invention has been proposed in order to achieve the above-mentioned object, and the invention according to claim 1 is characterized in that the high-pressure cleaning has the flexibility to hold the high-pressure cleaning hose and perform the cleaning operation with high-pressure water. In order to prevent the body from receiving the high-pressure water jetted or ejected from the hose,
Inner diameter greater than the outer diameter of the high-pressure cleaning hose, and a tubular protective cover of compressive strength to withstand the pressure of the high pressure water detachably mounted on the outer periphery of the high-pressure cleaning hose, high pressure cleaning hose A protective cover body , comprising a reinforcing fiber material and a sheet-like resin material,
The protective cover body for the high-pressure washing hose is set in a resin injection mold with the reinforcing fiber material molded into a seamless cylindrical shape, and is molded by injecting the resin material in the resin injection mold, The resin material is provided on one side or both sides (front and back) of the reinforcing fiber material,
The reinforcing fiber material is made of a material of glass fiber, metal fiber, polypropylene fiber, polyethylene fiber, or polyarylate fiber, and the resin material is made of a material of nylon, polyethylene, or polystyrene .

この構成によれば、作業員等が掴む高圧洗浄ホース部分の外周に、筒状の保護カバー体を装着して高圧洗浄作業を行うことができる。そして、作業員等が掴む高圧洗浄ホースの部分、すなわち保護カバー体を装着させた高圧洗浄ホースの部分に破損等が生じた場合は、その破損等で生じた破片や漏れ出した高圧水は、保護カバー体の内側（内周面）に当たり、直接、周囲に飛散、あるいは作業員に当たることがない。このため、作業員や周囲の被害を最小限に抑えることができる。また、筒状の保護カバー体の内径を、高圧洗浄ホースの外径よりも大きく形成してあるので、高圧洗浄ホースに対する着脱を容易に行うことができる。
この構成によれば、作業員は、保護カバー体の外側から、この保護カバー体と一緒に高圧洗浄ホースを掴み、その掴んだ手で高圧洗浄ホースの向き等を操作することができる。
この構成によれば、補強繊維材料と樹脂材料とを使用して、耐圧力性を保有し、かつ軽量で操作性の良い保護カバー体が得られる。
この構成によれば、補強繊維材料の一面側又は両面側に樹脂材料を積層配置して、耐圧力性と軽量性が確保された操作性の良い保護カバー体が得られる。また、補強繊維材料の表面を樹脂材料で被覆することにより、高圧洗浄ホースと保護カバー体との間の摩擦抵抗を低減させて高圧洗浄ホースの摩耗を減らし、また作業員が掴むときの触感を向上させることができる。 According to this configuration, it is possible to perform the high-pressure washing operation by attaching the cylindrical protective cover body to the outer periphery of the high-pressure washing hose portion that is held by an operator or the like. And when the part of the high-pressure washing hose gripped by the worker, that is, the part of the high-pressure washing hose with the protective cover body attached is damaged, the fragments generated by the damage etc. and the leaked high-pressure water are It hits the inside (inner peripheral surface) of the protective cover body and does not scatter directly or hit workers. For this reason, damage to workers and surroundings can be minimized. In addition, since the inner diameter of the cylindrical protective cover body is formed larger than the outer diameter of the high-pressure washing hose, it can be easily attached to and detached from the high-pressure washing hose.
According to this configuration, the worker can grasp the high-pressure washing hose together with the protective cover body from the outside of the protective cover body, and operate the direction of the high-pressure washing hose with the grasped hand.
According to this configuration, a protective cover body having pressure resistance, light weight and good operability can be obtained by using the reinforcing fiber material and the resin material.
According to this configuration, a protective cover body with good operability in which pressure resistance and light weight are ensured can be obtained by laminating and arranging resin materials on one side or both sides of the reinforcing fiber material. In addition, by covering the surface of the reinforcing fiber material with a resin material, the friction resistance between the high pressure washing hose and the protective cover body is reduced to reduce the wear of the high pressure washing hose, and the tactile sensation when the worker grips it. Can be improved.

請求項２に係る本発明は、前記高圧洗浄ホース用保護カバー体は、前記内径を前記高圧洗浄ホースの前記外径の略２倍の大きさに設定してなる、ことを特徴とする。 The present invention according to claim 2 is characterized in that the high pressure cleaning hose protective cover body has the inner diameter set to be approximately twice the outer diameter of the high pressure cleaning hose.

この構成によれば、筒状の保護カバー体の内径を高圧洗浄ホースの外径の略２倍の大きさに設定し、保護カバー体と高圧洗浄ホースの間に十分な隙間を確保しているので、高圧洗浄ホースに対して保護カバー体を着脱する際等に、保護カバー体を高圧洗浄ホースに対してスライドさせて容易に着脱することができる。   According to this configuration, the inner diameter of the cylindrical protective cover body is set to approximately twice the outer diameter of the high pressure washing hose, and a sufficient gap is secured between the protective cover body and the high pressure washing hose. Therefore, when attaching / detaching the protective cover body to / from the high-pressure washing hose, the protective cover body can be easily attached / detached by sliding with respect to the high-pressure washing hose.

本発明によれば、作業員等が高圧洗浄ホースを掴む部分の外周に、筒状の保護カバー体を装着して使用するので、保護カバー体を装着させた高圧洗浄ホースの部分に破損等が生じた場合、その破片や漏れ出した水は、保護カバー体の内側（内周面）に当たり、直接、周囲に飛散、あるいは作業員に当たることがない。これにより、作業員や周囲の被害を最小限に抑えることができ、安全性の向上に寄与できる。また、筒状の保護カバー体の内径を、高圧洗浄ホースの外径よりも大きく形成してあるので、高圧洗浄ホースに対する着脱を容易に行うことができ、作業性の向上に寄与できる。   According to the present invention, since a cylindrical protective cover body is attached to the outer periphery of a portion where an operator or the like grips the high pressure cleaning hose, the portion of the high pressure cleaning hose to which the protective cover body is attached is damaged. If it occurs, the fragments or leaked water hits the inner side (inner peripheral surface) of the protective cover body and does not directly scatter or hit workers. As a result, damage to workers and surroundings can be minimized, which can contribute to improvement of safety. Further, since the inner diameter of the cylindrical protective cover body is formed larger than the outer diameter of the high-pressure washing hose, it can be easily attached to and detached from the high-pressure washing hose, contributing to improvement in workability.

It is A sectional view.

本発明に係る高圧洗浄ホース用保護具は、図１、図２、図３、図５に示すように、両端部がそれぞれ開口している筒状の保護カバー体１１（以下、単に「保護カバー体１１」という）として形成されている。その高圧洗浄ホース用保護具、すなわち保護カバー体１１は、図１から図３に示すように高圧洗浄ホース２１の一部を被覆した状態で、その高圧洗浄ホース２１の外周に装着して使用される。   As shown in FIG. 1, FIG. 2, FIG. 3, and FIG. 5, the protector for a high-pressure washing hose according to the present invention has a cylindrical protective cover body 11 (hereinafter simply referred to as “protective cover”) having both ends opened. Body 11 ”). The high pressure cleaning hose protector, that is, the protective cover body 11 is used by being attached to the outer periphery of the high pressure cleaning hose 21 in a state of covering a part of the high pressure cleaning hose 21 as shown in FIGS. The

前記高圧洗浄ホース２１は、先端部（一端部）に洗浄水を高圧（例えば３０ＭＰａ〜５０ＭＰａ）で噴射するノズル２２を取り付け、他端側は図示しない高圧水源に接続して使用される。なお、高圧洗浄ホース２１の外径は約２０ミリ、ノズル２２の最大外径は約３５ミリである。なお、これら各寸法は、用途に応じて適宜変更されるものである。   The high-pressure washing hose 21 is used by attaching a nozzle 22 for injecting washing water at a high pressure (for example, 30 MPa to 50 MPa) at the tip (one end) and connecting the other end to a high-pressure water source (not shown). The outer diameter of the high pressure washing hose 21 is about 20 mm, and the maximum outer diameter of the nozzle 22 is about 35 mm. Each of these dimensions is appropriately changed according to the application.

一方、保護カバー体１１は、内径が高圧洗浄ホース２１の外径の略２倍の大きさ、すなわち保護カバー体１１と高圧洗浄ホース２１との間に十分な隙間を確保できる大きさに設定してあり、本例での内径は約４０ミリである。また、保護カバー体１１の厚みは約１０ミリであり、したがって外径は約６０ミリである。さらに、図１に示す保護カバー体１１の長さ（全長）Ｌは、約２メートルである。この保護カバー体１１の長さＬは、高圧洗浄ホース２１が破裂等を起こして、その高圧洗浄ホース２１における破片の飛散や噴出した水により作業員Ｍがケガ等しないように保護できる長さである。したがって、保護カバー体１１には、高圧洗浄ホース２１が破裂等を起こして、その破片が飛散することによる外圧や噴出した水からの外圧等である、所謂、所定の外圧に十分に耐え得る大きさの強度、すなわち、それら破片や水が貫通しない耐圧強度が持たされている。なお、保護カバー体１１の前記長さＬ寸法、や内径、外径等の各寸法も、用途や保護カバー体１１の材質等によっても適宜変更されるものである。   On the other hand, the protective cover 11 is set to have an inner diameter that is approximately twice the outer diameter of the high-pressure washing hose 21, that is, a size that can secure a sufficient gap between the protective cover 11 and the high-pressure washing hose 21. The inner diameter in this example is about 40 mm. Further, the thickness of the protective cover body 11 is about 10 mm, and therefore the outer diameter is about 60 mm. Furthermore, the length (full length) L of the protective cover body 11 shown in FIG. 1 is about 2 meters. The length L of the protective cover body 11 is a length that can protect the worker M from being injured by the high pressure cleaning hose 21 being ruptured and the like by the scattering of splinters and the jetted water in the high pressure cleaning hose 21. is there. Therefore, the protective cover body 11 is sufficiently large to withstand a so-called predetermined external pressure, such as an external pressure caused by the high-pressure washing hose 21 bursting or the like, and an external pressure due to the fragments being scattered or an external pressure from the jetted water. Strength, i.e., pressure resistance against penetration of the fragments and water. It should be noted that the length L dimension of the protective cover body 11 and the dimensions such as the inner diameter and the outer diameter are appropriately changed depending on the application, the material of the protective cover body 11, and the like.

また、前記保護カバー体１１は、前記高圧洗浄ホース２１がノズル２２側から保護カバー体１１内に挿入され、そのノズル２２が前記保護カバー体１１内を貫通して、保護カバー体１１の他端側から完全に突出するまで挿入され、図１から図３に示すように高圧洗浄ホース２１の途中の箇所における外周、すなわち作業員Ｍが手Ｍａで掴んで操作する箇所付近に配置して使用される。   The protective cover body 11 includes the high-pressure washing hose 21 inserted into the protective cover body 11 from the nozzle 22 side, and the nozzle 22 penetrates the protective cover body 11 and the other end of the protective cover body 11. It is inserted until it protrudes completely from the side, and as shown in FIGS. 1 to 3, it is used by being arranged near the outer periphery of the high pressure washing hose 21 in the middle, that is, near the place where the operator M holds and operates the hand Ma. The

また、このようにして高圧洗浄ホース２１の操作箇所付近に配置された保護カバー体１１には、柔軟性を保有させている。そして、図３に示すように、作業員Ｍが手Ｍａで、保護カバー体１１を外側から掴むと弾性変形をして潰れ、該保護カバー体１１を介して高圧洗浄ホース２１もしっかりと掴むことができる。そして、高圧洗浄ホース２１を掴んで、該高圧洗浄ホース２１の前後方向への押し・引き操作、あるいは上下及び左右方向への振り向け操作等を自由に行うことができるようになっている。   Further, the protective cover body 11 arranged in the vicinity of the operation location of the high-pressure washing hose 21 in this way has flexibility. As shown in FIG. 3, when the worker M grasps the protective cover body 11 from the outside with his hand Ma, the worker M is elastically deformed and crushed, and the high pressure washing hose 21 is firmly grasped via the protective cover body 11. Can do. Then, the high pressure washing hose 21 can be grasped, and the high pressure washing hose 21 can be freely pushed and pulled in the front-rear direction, or directed up and down and left and right.

なお、保護カバー体１１における上記所定の外圧に十分に耐得る大きさの強度、すなわち上記耐圧強度と、作業員Ｍが手Ｍａで保護カバー体１１を外側より掴むと弾性変形をして潰れて、該保護カバー体１１を介して高圧洗浄ホース２１も一緒に掴むことができるようにした柔軟性と、を有する構造としては、図４及び図５に実施例１として示すように、例えば耐圧力性と柔軟性とを保有し、しかも軽量で操作性のよい補強繊維材料１２をシームレス状の円筒形に成形して使用する。また、その補強繊維材料１２としては、アラミド繊維、ガラス繊維、金属繊維、ポリエステル繊維、ポリプロピレン繊維、ポリエチレン繊維、ポリアリレート繊維等の、各繊維を組紐状等に織り固めた材料の使用があげられる。   It should be noted that the protection cover body 11 has a strength that can sufficiently withstand the predetermined external pressure, that is, the pressure resistance strength, and when the operator M grips the protection cover body 11 from the outside with the hand Ma, it is elastically deformed and crushed. As the structure having the flexibility so that the high-pressure washing hose 21 can also be grasped together through the protective cover body 11, as shown in FIG. 4 and FIG. Reinforcing fiber material 12 that possesses high performance and flexibility, is lightweight, and has good operability is molded into a seamless cylindrical shape and used. Further, as the reinforcing fiber material 12, use of a material in which each fiber is woven into a braid or the like such as aramid fiber, glass fiber, metal fiber, polyester fiber, polypropylene fiber, polyethylene fiber, polyarylate fiber and the like can be mentioned. .

したがって、本実施形態のように、高圧洗浄ホース２１の、作業員Ｍが手Ｍａで掴んで操作する箇所部分等に、高圧洗浄ホース用保護具である上記構成の保護カバー体１１を装着して使用すると、保護カバー体１１を装着させた高圧洗浄ホース２１の部分に破損等が生じて、破片が飛散したようなときには、飛散した破片は保護カバー体１１の内側（内周面）に当たり、直接、周囲に飛散して作業員Ｍ等に当たることがない。また、破損した箇所部分から噴出した水も、破片と同様に保護カバー体１１の内側（内周面）に当たり、直接周囲に飛散して作業員等に当たることがない。このため、作業員Ｍや周囲の被害を最小限に抑えることができ、安全性に寄与できる。   Therefore, as in the present embodiment, the protective cover body 11 having the above-described configuration, which is a high-pressure cleaning hose protector, is attached to a portion of the high-pressure cleaning hose 21 that the operator M holds and operates with the hand Ma. When used, when the high pressure cleaning hose 21 to which the protective cover body 11 is attached is damaged, and the broken pieces are scattered, the scattered pieces hit the inner side (inner peripheral surface) of the protective cover body 11 and directly , It does not scatter around and hit the worker M or the like. Moreover, the water spouted from the damaged part hits the inner side (inner peripheral surface) of the protective cover body 11 as in the case of the broken pieces, and is not directly scattered around and hitting an operator or the like. For this reason, it is possible to minimize damage to the worker M and the surroundings, and contribute to safety.

また、保護カバー体１１の内径が、高圧洗浄ホース２１の外径よりも大きく、すなわち保護カバー体１１の内径を高圧洗浄ホース２１の外径の略２倍の大きさに設定し、保護カバー体１１と高圧洗浄ホース２１の間に十分な隙間を確保しているので、高圧洗浄ホース２１に対して保護カバー体１１を着脱する際等に、保護カバー体１１を高圧洗浄ホース２１に対してスライドさせて容易に着脱することができる。   Further, the inner diameter of the protective cover body 11 is larger than the outer diameter of the high-pressure washing hose 21, that is, the inner diameter of the protective cover body 11 is set to approximately twice the outer diameter of the high-pressure washing hose 21, Since a sufficient gap is secured between the high pressure cleaning hose 21 and the high pressure cleaning hose 21, the protective cover body 11 is slid relative to the high pressure cleaning hose 21 when the protective cover body 11 is attached to or detached from the high pressure cleaning hose 21. Can be easily attached and detached.

なお、前記保護カバー体１１の構造、すなわち物理的な上記耐圧強度と、上記柔軟性を保有した保護カバー体１１は、次の図６に示す実施例２及び図７に示す実施例３で各々説明するように、上記織り固めた補強繊維材料１２と樹脂材料１３とを任意に組み合わせた構造にすることによっても達成ができる。   In addition, the structure of the said protective cover body 11, ie, the said physical withstand pressure strength, and the protective cover body 11 which has the said softness | flexibility, respectively in Example 2 shown in the following FIG. 6, and Example 3 shown in FIG. As will be described, this can also be achieved by using a structure in which the reinforced reinforcing fiber material 12 and the resin material 13 are arbitrarily combined.

（実施例２）
実施例２は、図６に示すように、織り固めた補強繊維材料１２の一面（表面）側に熱可塑性の樹脂材料１３を積層配置し、その補強繊維材料１２と樹脂材料１３とをシームレス状の円筒形に一体成形して使用するようにしたものである。樹脂材料１３としては、ポリ塩化ビニル、ナイロン、ポリエチレン、ポリスチレン等の材料の使用があげられる。 (Example 2)
In Example 2, as shown in FIG. 6, a thermoplastic resin material 13 is laminated on one surface (surface) side of the reinforced reinforcing fiber material 12, and the reinforcing fiber material 12 and the resin material 13 are seamlessly formed. It is designed to be used by being integrally formed into a cylindrical shape. Examples of the resin material 13 include materials such as polyvinyl chloride, nylon, polyethylene, and polystyrene.

また、実施例２の構造では、円筒形に織り固めた補強繊維材料１２の外側に、樹脂材料１３でなるシート状の部材を貼り付けてなる構造としてもよい。シート状の樹脂材料１３を貼り付けた場合では、その樹脂材料１３の表面に例えば製品名、会社名などを印刷表示することも簡単にできる。さらに、シームレス状の円筒形に成形した補強繊維材料１２を図示しない樹脂射出成形型にセットし、その樹脂射出成形型内で補強繊維材料１２の一面（表面）側に熱可塑性の樹脂材料１３を射出して成形する構造としてもよい。このように、補強繊維材料１２と樹脂材料１３とで二層構造にすると、耐圧力性が増した保護カバー体１１が得られる。なお、樹脂材料１３は、補強繊維材料１２の表面側ではなく、補強繊維材料１２の裏面側に設けた構造としてもよい。   Moreover, in the structure of Example 2, it is good also as a structure formed by affixing a sheet-like member made of the resin material 13 to the outside of the reinforcing fiber material 12 woven into a cylindrical shape. In the case where the sheet-like resin material 13 is pasted, for example, a product name, a company name, or the like can be printed and displayed on the surface of the resin material 13. Further, the reinforcing fiber material 12 molded into a seamless cylindrical shape is set in a resin injection mold (not shown), and the thermoplastic resin material 13 is placed on one side (surface) side of the reinforcing fiber material 12 in the resin injection mold. It is good also as a structure injected and shape | molded. Thus, when the two-layer structure is formed by the reinforcing fiber material 12 and the resin material 13, the protective cover body 11 having an increased pressure resistance is obtained. The resin material 13 may have a structure provided not on the front surface side of the reinforcing fiber material 12 but on the back surface side of the reinforcing fiber material 12.

（実施例３）
実施例３は、図７に示すように、補強繊維材料１２の両面（表面と裏面）側にそれぞれ熱可塑性の樹脂材料１３であるシート状の部材を積層配置し、その補強繊維材料１２と樹脂材料１３とをシームレス状の円筒形に一体成形して使用するようにしたものである。 Example 3
In Example 3, as shown in FIG. 7, sheet-like members, which are thermoplastic resin materials 13, are laminated on both surfaces (front and back surfaces) of the reinforcing fiber material 12, and the reinforcing fiber material 12 and the resin are laminated. The material 13 is integrally formed into a seamless cylindrical shape for use.

また、実施例３の構造では、円筒形に成形した補強繊維材料１２の表側と裏側の両方に、樹脂材料１３でなるシート状の部材を各々貼り付けてなる三層構造としてもよい。さらに、シームレス状の円筒形に成形した補強繊維材料１２を図示しない樹脂射出成形型にセットし、その樹脂射出成形型内で樹脂材料１３を射出して成形し、補強繊維材料１２の両面（表面と裏面）側に樹脂材料１３を各々設けた構造としてもよい。このように、補強繊維材料１２と樹脂材料１３とで三層構造にすると、耐圧力性が更に増した保護カバー体１１が得られる。   Moreover, in the structure of Example 3, it is good also as a three-layer structure which affixes the sheet-like member which consists of the resin material 13 on both the front side and the back side of the reinforcing fiber material 12 shape | molded by the cylindrical shape, respectively. Further, the reinforcing fiber material 12 formed into a seamless cylindrical shape is set in a resin injection mold (not shown), the resin material 13 is injected and molded in the resin injection mold, and both surfaces (surfaces) of the reinforcing fiber material 12 are formed. Further, the resin material 13 may be provided on the back surface side. Thus, when the reinforcing fiber material 12 and the resin material 13 form a three-layer structure, the protective cover body 11 with further increased pressure resistance can be obtained.
