Description

【０００１】
【発明の属する技術分野】
本発明は、互いに組付け可能な基台と蓋体とで構成され、内部に給水湯管等を収容して保護する配管保護カバーに関するものである。
【０００２】
【従来の技術】
従来の配管保護カバーとして、実公平６−１８３１２号公報に開示されているものが知られており、これが図６に示されている。図６において、この保護カバーＣ’は、相互に組み付けられる基台５１と蓋体５２とから成り、蓋体５２の開口部を断熱材５３により閉塞して、基台５１の両側壁部５１ａの外周と、蓋体５２の内周との間に形成される空気層５４により断熱性を高める構成である。
【０００３】
上記保護カバーＣ’では、別体の断熱材５３が必要となり、しかも、この断熱材５３を蓋体５２の天板部の裏面に貼り付けたりするのが、大変に面倒な作業であった。また、前記断熱材５３、或いは蓋体５２の開口幅の寸法誤差や、該開口部への断熱材５３の嵌入不十分等によって、蓋体開口部の閉塞が完全でない場合が多く、基台５１の内部と完全に隔離された空気層を設けることは困難であるために、十分な断熱効果が得られなかった。
【０００４】
【発明が解決しようとする課題】
本発明は、別体の断熱材等を使用せずに、構造自体によって高い断熱効果が得られる配管保護カバーの提供を課題としている。
【０００５】
【課題を解決するための手段】
この課題を解決するための請求項１の発明は、各嵌合部の嵌合により互いに組付け可能な基台と蓋体とで構成され、内部に給水湯管等の配管を収容して保護する配管保護カバーであって、前記蓋体は、外壁部と、該外壁部と所定間隔をおいて該外壁部に沿って形成される内壁部とを備え、断面視において前記外壁部及び内壁部の間に密閉され、かつ連続した空気層となる中空部が形成されて、蓋体の前記中空部は、基台と蓋体とが組み付けられた状態で、基台内部に収容された配管の上方、及び両側方にそれぞれ形成され、前記基台の両側壁部が基台内部に収容された配管に弾接した状態において、前記基台内部に収容された配管の上方及び両側方に、前記中空部により形成された空気層と異なる第２の空気層 を形成すべく、前記蓋体の内面は、基台の両側壁部、及びこれに連続する配管の上端部と離れて形成されていることを特徴としている。
【０００６】
請求項１の発明によれば、蓋体には、断面視において連続した空気層となる中空部が形成されて、該中空部は、基台と蓋体とが一体に組み付けられた状態で、基台内部に収容された配管の上方、及び両側方に配置されるように形成され、しかも基台と蓋体とが組み付けられた状態において、前記蓋体の内面と、基台内部に収容される配管、及び基台の両側壁部との間に、前記中空部により基台に形成された空気層とは異なる第２の空気層が形成されていて、前記配管は内外二層の空気層で覆われるために、保護カバーの構造自体によって断熱性が一層に高められる。このように、保護カバーの構造自体によって高い断熱性が得られるため、別体の断熱材等を使用する必要がなくなって、その貼付け作業等が不要となり、配管の施工性も高まる。
【０００７】
また、請求項２の発明は、請求項１の発明において、前記蓋体は、前記蓋体の外方又は内方から作用する衝撃を吸収可能とすべく、前記中空部を形成する外壁部又は内壁部が、該中空部の内方に変形可能に形成された構成であるので、請求項１の発明の上記作用効果に加えて、蓋体に作用する衝撃力を効果的に吸収できる。更に、請求項３の発明は、請求項１又は２の発明において、前記蓋体の嵌合部が中空構造になっているために、保護カバーの構造自体による断熱性が一層に高められる。
【０００８】
【発明の実施の形態】
以下、実施例を挙げて、本発明を更に詳細に説明する。図１は、本発明の第１実施例の配管保護カバーＣ1 内に給水湯管Ｐを収容した状態の部分斜視図であり、図２は、同じく横断面図であり、図３は、配管保護カバーＣ1 の分解斜視図であり、図４は、同じく分解状態の横断面図である。図１ないし図４において、配管保護カバーＣ1 は、互いに組み付けられる基台１０と蓋体２０とから成り、この基台１０と蓋体２０は、いずれも長尺状をした樹脂の押出成形品である。基台１０は、断面略Ｕ字状をしていて、底壁部１１の幅方向の両端部に、それぞれ側壁部１２が起立された構成であって、両側壁部１２の基端部は、外方に向けて屈曲形成されて、側壁部１２の基端部と、前記底壁部１１の幅方向の両端部との間の凹状となった部分は嵌合凹部１３となっている。また、両側壁部１２の基端部の外方に屈曲した部分の内側には、この両側壁部１２の間に収容される給水湯管Ｐの下端部の両側を支持するための支持突起部１４がそれぞれ垂直に形成されている。また、両側壁部１２は、弾性変形可能であって、その上端部は、内方に向けて緩やかにわん曲されて、両側壁部１２の間に収容される給水湯管Ｐの外周面に弾接可能になっている。また、底壁部１１の幅方向の両端部には、設置板部１５が段差状となって設けられて、設置状態において、前記底壁部１１の裏面には、空隙部が形成される。
【０００９】
一方、蓋体２０は、断面逆Ｕ字状であって、しかも、断面視において中空筒状をしており、天壁部２１の幅方向の両端に側壁部２２がそれぞれ下方に向けて連設され、更に、各側壁部２２の下端部の内側には、前記基台１０の嵌合凹部１３に嵌合される嵌合凸部２３が設けられた構成である。また、前記天壁部２１、両側壁部２２及び両嵌合凸部２３の部分は、いずれも中空状に成形されて、断面視において密閉された逆Ｕ字状の空気層２４が形成されている。また、この蓋体２０は、前記空気層２４を主体にして見ると、その内外には、それぞれ内壁部２５及び外壁部２６が設けられて、これらの各壁部２５，２６は、いずれも内方に向けて変形可能になっている。また、内壁部２５における側壁部２２の部分は、基台１０と蓋体２０とを組み付けた状態において、基台１０の側壁部１２との間に空気層２７が形成可能なように、外壁部２６に近接した状態で、基台１０の側壁部１２と略平行となっている。また、内壁部２５における天壁部２１の部分は、給水湯管Ｐとの間に空気層２７が形成可能なように、円弧状に成形されている。
【００１０】
このため、基台１０の両側壁部１２の間に給水湯管Ｐを収容した状態で、前記基台１０に対して蓋体２０を上方から押し込むと、その嵌合凸部２３が、基台１０の両側壁部１２の外面に弾接することにより、その両側壁部２２の部分が外方に弾性変形されて、前記嵌合凸部２３が基台１０の嵌合凹部１３の部分に達すると、蓋体２０の両側壁部２２が原形状に復元して、基台１０の嵌合凹部１３と蓋体２０の嵌合凸部２３とが互いに嵌合されて、基台１０と蓋体２０とが一体に組み付けられる。ここで、蓋体２０の両側壁部２２は、空気層２４を有していて、薄肉の内壁部２５が弾性変形し易い構造になっている結果、前記両側壁部２２そのものが弾性変形し易くなって、基台１０の嵌合凹部１３と蓋体２０の嵌合凸部２３との嵌合が容易となる。また、上記状態においては、基台１０の両側壁部１２の略上半部は、この両側壁部１２の間に収容された給水湯管Ｐの外周面に弾接しているために、基台１０の両側壁部１２、及びこれに連続する給水湯管Ｐの上端部と、蓋体２０の内壁部２５との間には、所定の隙間が形成されて、該隙間は、他の部分と隔離された空気層２７となっている。
【００１１】
このように、本実施例の配管保護カバーＣ1 は、これを構成する蓋体２０の断面視の全域に亘って外部と密閉された空気層２４が設けられ、しかも、基台１０と蓋体２０とを相互に組み付けることにより、蓋体２０の構造自体によって、その内部に設けられた前記空気層２４とは別の空気層２７が形成され、両空気層２４，２７が相乗して、断熱材等の別部材を使用せずに、高い断熱効果が発揮される。
【００１２】
また、本実施例の配管保護カバーＣ1 は、その蓋体２０を中空筒状に形成している内壁部２５又は外壁部２６が内方に向けて変形可能となっているために、前記蓋体２０に外方から衝撃が作用したり、或いは収容した給水湯管Ｐに通水湯されて、前記給水湯管Ｐが踊ったりして、前記蓋体２０に内方から衝撃が作用した場合には、前記内壁部２５又は外壁部２６が変形して、前記衝撃が効果的に吸収される。
【００１３】
なお、前記した配管保護カバーＣ1 は、断面視において、全体が一つの中空筒状となって、その中空部である空気層２４は、断面視において連続しているが、全体としての中空部内に１ないし複数の隔離壁部が設けられて、断面視において複数の中空部が存在する構成にすることも可能である。この構造であると、前記隔離壁部の存在によって、蓋体の強度が高まる。
【００１４】
引き続いて、図５を参照にして、本発明の第２実施例の配管保護カバーＣ2 について説明する。この保護カバーＣ2 は、互いに組み付けられる基台３０と蓋体４０とから成る。基台３０は、底壁部３１の両端部に側壁部３２が設けられた構成であって、各側壁部３２の略下半部は、厚肉に成形されていると共に、その略上半部は、薄肉板状に成形されていて、各側壁部３２の略上半部の外側には、それぞれ嵌合凸部３３が設けられている。また、底壁部３１には、断面長方形状の空気層３４を形成する中空部が設けられていると共に、前記各側壁部３２の略下半部の厚肉に成形された部分には、空気層３５を形成する中空部がそれぞれ設けられている。
【００１５】
一方、蓋体４０は、天壁部４１の幅方向の両端部に下方に向けて側壁部４２がそれぞれ連設されて、各側壁部４２の上端部の内側の部分に、前記嵌合凸部３３と嵌合される嵌合凹部４３が設けられ、前記天壁部４１及び前記各側壁部４２には、ほぼその全域に亘って空気層４４を形成する中空部が設けられた構成である。このため、前記蓋体４０は、前記空気層４４を主体にして見ると、その内外には、それぞれ内壁部４５及び外壁部４６が設けられて、これらの各壁部４５，４６は、いずれも内方に向けて変形可能となっている。そして、基台３０の両側壁部３２の間に給水湯管Ｐを収容した状態で、該基台３０に対して蓋体４０を押し込むと、両側壁部４２、特に側壁部４２を構成する内壁部４５が外方に弾性変形して、その嵌合凹部４３に、基台３０の嵌合凸部３３が嵌合されると、前記両側壁部４２は、原形状に復元して、基台３０と蓋体４０とが一体に組み付けられる。この組付け状態においては、蓋体４０の内壁部４５及び基台３０の両側壁部３２の内面と、給水湯管Ｐの外面との間に、基台３０と蓋体４０との組付けによる空気層４７が形成される。
【００１６】
このように、第２実施例の配管保護カバーＣ2 は、これを構成する基台３０と蓋体４０との双方に空気層３４，３５，４４が設けられていることに特徴があって、保護カバーＣ2 を構成する基台３０と蓋体４０の構造自体によって、給水湯管Ｐの収容状態において、ほぼその全周に亘って空気層を設けることができて、断熱効果が一層高まる利点がある。また、基台３０と蓋体４０との組付けにより形成される空気層４７も断熱性の向上に寄与する。更に、蓋体４０には、その断面視の全域に亘って空気層４４が形成されていて、該空気層４４を形成する内壁部４５及び外壁部４６が薄肉状となるために、内外から蓋体４０に作用する衝撃は、効果的に吸収される利点もある。
【００１７】
また、本発明を実施可能な配管保護カバーとは、上記した基台１０，３０及び蓋体２０，４０のような長尺状のものに限られず、所定長に切断されて設置された前記基台１０，３０及び蓋体２０，４０を、その直線接続部、或いは屈曲接続部において接続するための長さの短い接続部保護カバーに対しても実施可能である。このような短い接続部保護カバーは、射出成形されることが多いので、その天壁部、或いは側壁部に成形される中空部は、配管方向に沿って隔壁部が設けられて、該配管方向に沿って断続した構造であってもよい。更に、本発明を実施可能な配管保護カバーとは、上記したような給水湯管に限られず、空調用冷媒管等を収容するための空調用の配管保護カバーに対しても実施可能である。
【００１８】
なお、基台と蓋体とからなる配管保護カバーにおいて、蓋体の側壁部の下端部が基台の底壁部の側に廻り込んでいる形状のものにおいて、この廻り込んだ部分を中空構造にして、該部分にも空気層を設けると、蓋体のほぼ全周に亘って空気層が設けられて、その断熱性が一層高められる。
【００１９】
【発明の効果】
本発明に係る配管保護カバーは、これを構成する蓋体に、基台と蓋体との組付け状態で基台内部に収容された配管の上方、及び両側方に配置された空気層となる中空部が形成されているのに加えて、前記組付け状態で、基台の両側壁部が配管に弾接して、基台内部に収容された配管の上方、及び両側方に、前記空気層とは異なる第２の空気層が形成されて、前記配管の上方、及び両側方は、内外二層の空気層によって覆われる。よって、本発明に係る配管保護カバーは、別体の断熱材等を使用せずに、構造自体によって高い断熱効果を得ることができると共に、別体の断熱材等を使用しないために、その貼付け作業等が不要となって、施工性も高まる。
