【発明の属する技術分野】
この発明は、配管カバー部材に関し、更に詳細には、所要形状をなす配管ジョイントにおける一方の外側面に整合する第１凹面部を凹設した第１半体と、この第１半体と一体または別体に形成され、前記配管ジョイントにおける他方の外側面に整合する第２凹面部を凹設した第２半体とからなり、各々の凹面部を前記配管ジョイントに整合させることで前記第１半体および第２半体の内部に該配管ジョイントを収容し得るようにした配管カバー部材に関するものである。
【０００２】
【従来の技術】
例えば、流体や気体等の種々流体を流通案内を図るために、パイプ状の配管材等が好適に実施に供されている。この配管材は、形状別に区分すると、所要長の直管や、２本以上の直管同士を所要角度で相互連結する配管ジョイント(継手)等に分類される。また、この配管材を材質別に区分すると、鋼管、鉄管、銅管、ステンレス管、塩化ビニル管、ポリエチレン管等に分類される。ここで、前記配管ジョイントは、Ｉ形、Ｌ形、Ｔ形、Ｙ形等の様々な形態のものが実用化されている。
【０００３】
そして、(a)配管材の内部を流通する流体の保温、(b)流体温度と外気温度との差による配管材表面の結露防止、(c)種々物品が衝突した際の配管材の破損防止、(d)人体が衝突した際の負傷防止(衝撃緩和)、等を図る必要がある場合には、筒体状を呈する配管カバー部材を前記直管や配管ジョイントの外側に被着するようになっている。この配管カバー部材は、断熱性および弾力性を有することを前提として、(1)ポリオレフィン、ポリウレタン、ポリエチレン、ゴム等に代表される「化学合成物系」、(2)コルク、ダンボール等に代表される「動植物系」、(3)ガラス繊維、石綿、ロックウール(岩綿)、パーライト、ケイ酸カルシウム等に代表される「無機質系」等に分類される。
【０００４】
例えば図９は、９０度に屈曲するＬ形の配管ジョイントとされるステンレス製のメカニカルジョイントＪと、このメカニカルジョイントＪに連結される直管Ｐ,Ｐと、前記メカニカルジョイントＪの外側に被着される配管カバー部材２０とを例示した概略斜視図である。前記メカニカルジョイントＪは、略Ｌ形に形成された屈曲筒体状の本体１０と、前記直管Ｐ,Ｐをこの本体１０の夫々の開口端に連結するために該本体１０に螺合されるナット１２,１２とから構成されている。また前記配管カバー部材２０は、例えばポリエチレンフォーム等の弾力性および柔軟性を有する素材を材質とし、前述したＬ形形状をなすメカニカルジョイントＪにおける一方の外側面(図示下面)に整合する第１凹面部２６を凹設した第１半体２２と、この第１半体２２とは別体に形成され、前記メカニカルジョイントＪにおける他方の外側面(図示上面)に整合する第２凹面部２８を凹設した第２半体２４とから構成されている。このような配管カバー部材２０は、前記各々の凹面部２６,２８を前記メカニカルジョイントＪに整合させることで、前記第１半体２２および第２半体２４の内部に該メカニカルジョイントＪを収容し得るようになっている。
【０００５】
【発明が解決しようとする課題】
ところで前記メカニカルジョイントＪは、同一口径の前記直管Ｐ,Ｐを連結するＬ形タイプであっても、これを生産するメーカー毎に形状やサイズが僅かずつ異なっている場合が多い。具体的には、前記本体１０の屈曲度合および延在長や、前記ナット１２の外形形状および長さ等が僅かずつ異なっている。このため、実用化されている各々のメカニカルジョイントＪに合致した形状の第１凹面部２６および第２凹面部２８を凹設した第１半体２２および第２半体２４からなる複数種類の配管カバー部材２０を予め製造しておき、収容されるべきメカニカルジョイントＪに対応した配管カバー部材２０を選択して使用しているのが実状であった。従って、(1)夫々の配管カバー部材２０を成形するための成形金型を準備する必要があることから製造コストが嵩んで製品価格が高くなる問題、(2)配管カバー部材の種類が多くなることから生産管理や在庫管理等が煩雑となる問題、等を内在していた。
【０００６】
【発明の目的】
本発明は、前述した課題を好適に解決するべく提案されたもので、形状および外形寸法が僅かずつ異なる複数種類の配管ジョイントを第１半体および第２半体の内部に安定的に収容し得るように構成することで、製造コスト低減による製品価格の低減や、生産管理および在庫管理の簡素化および合理化等を図り得るようにした配管カバー部材を提供することを目的とする。
【０００７】
【課題を解決するための手段】
前記課題を解決し、所期の目的を達成するため本発明は、配管ジョイントにおける一方の外側面に整合する第１凹面部を凹設した第１半体と、この第１半体と一体または別体に形成され、前記配管ジョイントにおける他方の外側面に整合する第２凹面部を凹設した第２半体とからなり、各々の凹面部を前記配管ジョイントに整合させることで前記第１半体および第２半体の内部に該配管ジョイントを収容し得るようにした配管カバー部材において、
前記第１凹面部および第２凹面部を、形状および外形寸法が異なる複数種類の配管ジョイントの何れにも整合し得る形状とし、
前記第１凹面部および第２凹面部に、前記複数種類の配管ジョイントにおける各々の開口端面に対応的に接触し得るリブ状突片からなる位置決め部を、該配管ジョイントの種類数だけ設けたことを特徴とする。
【０００８】
【発明の実施の形態】
次に、本発明に係る配管カバー部材につき、好適な実施例を挙げて、添付図面を参照しながら以下説明する。ここで本実施例では、配管ジョイントとして、図９に例示したＬ形タイプのメカニカルジョイントを例示することとし、このメカニカルジョイントに被着して該メカニカルジョイントを内部に収容する配管カバー部材について説明する。従って、図９に既出の部材や部位と同一の部材、部位については、同一の符号を付して説明する。
【０００９】
図１は、本発明の好適実施例に係る配管カバー部材３０を、メカニカルジョイントＪに被着する前の状態で示した概略斜視図である。本実施例の配管カバー部材３０は、略９０度に屈曲したＬ形タイプのメカニカルジョイントＪにおける一方の外側面(図示下面)に整合する第１凹面部２６を凹設した第１半体２２と、この第１半体２２とは別体に形成され、前記メカニカルジョイントＪにおける他方の外側面(図示上面)に整合する第２凹面部２８を凹設した第２半体２４とから構成されている。そして、前記第１凹面部２６および第２凹面部２８を前記メカニカルジョイントＪの外側面に夫々整合させることで第１半体２２および第２半体２４が該メカニカルジョイントＪに被着され、これによりこれら第１半体２２および第２半体２４の内部に該メカニカルジョイントＪを収容し得るようになっている。
【００１０】
そして実施例の配管カバー部材３０では、形状および外形寸法が僅かずつ異なる複数種類のメカニカルジョイント、具体的には図２(ａ)〜(ｃ)に示した３種類のメカニカルジョイントＪ(Ｊ１,Ｊ２,Ｊ３)の何れをも、第１半体２２および第２半体２４の内部に安定的に収容し得るようになっている。これら３種類は、何れも同一口径の前記直管Ｐ,Ｐを連結するＬ形タイプであるが、本体１０の屈曲態様(屈曲度合の大小)が微妙に異なっていると共に、ナット１２,１２の外形形状や長さＬが異なっている。また、本体１０における右側開口部の中心線と、本体左側に螺合したナット１２における開口端面１４との長さ寸法Ｓを外形寸法の基準とした場合、(ａ)のメカニカルジョイントＪ１が最小サイズの外形寸法を有し、(ｂ)のメカニカルジョイントＪ２が中間サイズの外形寸法を有し、(ｃ)のメカニカルジョイントＪ３が最大サイズの外形寸法を有している。
【００１１】
前述した３種類のメカニカルジョイントＪ１,Ｊ２,Ｊ３を安定的に収容し得る実施例の配管カバー部材３０では、前記第１半体２２および第２半体２４が基本的に同一形状とされており、例えば素材であるポリエチレン(ＰＥ)を発泡成形してなるポリエチレンフォームを材質とし、適度の弾力性および柔軟性を有している。このような第１半体２２および第２半体２４は、各々の第１凹面部２６および第２凹面部２８を、形状および外形寸法が僅かずつ異なる前記３種類のメカニカルジョイントＪ１,Ｊ２,Ｊ３の何れにも整合し得る形状とすることで、何れのメカニカルジョイントＪ１,Ｊ２,Ｊ３をも収容し得るようになっている。
【００１２】
すなわち第１凹面部２６および第２凹面部２８は、前述した各々のメカニカルジョイントＪ１,Ｊ２,Ｊ３における何れの本体１０にも整合し得る本体支持面部３２と、該メカニカルジョイントＪ１,Ｊ２,Ｊ３における何れのナット１２,１２にも整合し得るナット支持面部３４,３４とからなっている。但し、ここでいう整合とは、第１凹面部２６および第２凹面部２８がメカニカルジョイントＪ１,Ｊ２,Ｊ３の夫々の外面に対して完全に密着しつつ接触する態様の他に、部分的に隙間が画成された状態で接触する態様や、前記第１凹面部２６または第２凹面部２８が部分的に適度に変形した状態で接触する態様、等も含んでいる。また、夫々のナット支持面部３４,３４に隣接して、前記メカニカルジョイントＪ１,Ｊ２,Ｊ３に連結される前記直管Ｐ,Ｐに対応的に整合する直管支持面部３６,３６が凹設されている。
【００１３】
また、前記第１凹面部２６および第２凹面部２８におけるナット支持面部３４,３４の所要位置には、前記各々のメカニカルジョイントＪ１,Ｊ２,Ｊ３におけるナット１２,１２の開口端面１４に対応的に接触し得る位置決め部Ｔ(Ｔ１,Ｔ２,Ｔ３)が、該メカニカルジョイントＪ１,Ｊ２,Ｊ３の種類数だけ設けられている。これらメカニカルジョイントＪ１に対応する位置決め部Ｔ１、メカニカルジョイントＪ２に対応する位置決め部Ｔ２、メカニカルジョイントＪ３に対応する位置決め部Ｔ３は、何れも前記第１凹面部２６および第２凹面部２８に突設したリブ状突片とされている。また、第１半体２２および第２半体２４が前述した如く弾力性および柔軟性を有していることから、前記位置決め部Ｔ１,Ｔ２,Ｔ３も適度の弾力性および柔軟性を有しており、これにより該位置決め部Ｔ１,Ｔ２,Ｔ３は配管カバー部材３０の径方向(図４の上下方向)への圧潰的な変形が容易となっている。これにより、後述する如く、収容されるべき前記メカニカルジョイントＪ１,Ｊ２,Ｊ３に対して前記第１半体２２および第２半体２４を被着するに際し、当該メカニカルジョイントＪ１,Ｊ２,Ｊ３に接触して押圧される前記位置決め部Ｔ１,Ｔ２,Ｔ３は圧潰的に変形し、第１凹面部２６または第２凹面部２８の表面と略同一レベルまで押し潰されるようになっている。但し位置決め部Ｔ１,Ｔ２,Ｔ３は、配管カバー部材３０の軸方向(図４の左右方向)への変形、所謂撓曲的または剪断的な変形は困難となっている。
【００１４】
なお前記第１半体２２および第２半体２４は、前記メカニカルジョイントＪ１,Ｊ２,Ｊ３および直管Ｐ,Ｐに直接的に接触する内側発泡層２２Ａ,２４Ａと、この内側発泡層２２Ａ,２４Ａの外側に形成されて外部に露出する外側発泡層２２Ｂ,２４Ｂとからなる内外２重構造とされている。すなわち、流体温度によって高温になり得るメカニカルジョイントＪ１,Ｊ２,Ｊ３および直管Ｐ,Ｐに直接的に接触する内側発泡層２２Ａ,２４Ａは、耐熱性に優れた特性を有するポリエチレンフォームからなっており、外気や直射日光または風雨等に晒される可能性のある外側発泡層２２Ｂ,２４Ｂは、断熱性や耐候性等に優れた特性を有するポリエチレンフォームからなっている。
【００１５】
また、第１凹面部２６および第２凹面部２８における本体支持面部３２には、リブ状突片３８,３８が突設されている。このリブ状突片３８,３８は、第１半体２２および第２半体２４に対するメカニカルジョイントＪ１,Ｊ２,Ｊ３の位置決めを図る機能を有するものではなく、該メカニカルジョイントＪ１,Ｊ２,Ｊ３の本体１０外面を弾力的に支持して、該本体１０の安定化を図るために機能するものである。すなわち前記リブ状突片３８,３８の存在により、メカニカルジョイントＪ１,Ｊ２,Ｊ３の本体１０は、第１凹面部２６または第２凹面部２８における本体支持面部３２に完全に接触しなくとも安定的に整合するようになる。
【００１６】
【実施例の作用】
次に、前述した３種類のメカニカルジョイントＪ１,Ｊ２,Ｊ３の夫々に第１半体２２および第２半体２４を被着して、これらメカニカルジョイントＪ１,Ｊ２,Ｊ３を実施例の配管カバー部材３０の内部に収容する場合につき、具体的に図面を参照しながら説明する。
【００１７】
(メカニカルジョイントＪ１を収容する場合)
図３および図４は、図２(ａ)に例示した最小サイズの外形寸法を有するメカニカルジョイントＪ１に第１半体２２および第２半体２４を被着し、該メカニカルジョイントＪ１を実施例の配管カバー部材３０に収容する場合を例示した説明図である。このメカニカルジョイントＪ１におけるナット１２,１２の開口端面１４,１４に対しては、前記第１半体２２および第２半体２４の夫々に形成した位置決め部Ｔ１,Ｔ１が対応的に接触し得るように設定されている。従って、この位置決め部Ｔ１,Ｔ１を前記メカニカルジョイントＪ１の開口端面１４,１４に整合させることで(図３(ａ),図４(ａ))、該メカニカルジョイントＪ１に対する第１凹面部２６および第２凹面部２８の適切な整合が図られ、当該メカニカルジョイントＪ１に対して前記第１半体２２および第２半体２４を正確に被着できる(図３(ｂ),図４(ｂ))。
【００１８】
換言すると、最小サイズの外形寸法を有するメカニカルジョイントＪ１は、前記第１半体２２および第２半体２４からなる実施例の配管カバー部材３０の内部に、径方向の位置決めは勿論、軸方向の位置決めも適切に図られた状態で安定的に収容される(図４(ｂ))。そして、第１半体２２および第２半体２４の接合面同士が密着的に接合し、かつ第１半体２２および第２半体２４の夫々の直管支持面部３６,３６がメカニカルジョイントＪ１に連結された各々の直管Ｐ,Ｐの外面に密着することで、実施例の配管カバー部材３０の内部に収容された当該メカニカルジョイントＪ１は外部から完全に隔離される。従って、(a)メカニカルジョイントＪ１の内部を流通する流体の保温、(b)メカニカルジョイントＪ１表面の結露防止、(c)メカニカルジョイントＪ１の破損防止、(d)人体が衝突した際の負傷防止(衝撃緩和)、等が好適に図られる。
【００１９】
(メカニカルジョイントＪ２を収容する場合)
図５および図６は、図２(ｂ)に例示した中間サイズの外形寸法を有するメカニカルジョイントＪ２に第１半体２２および第２半体２４を被着し、該メカニカルジョイントＪ２を実施例の配管カバー部材３０に収容する場合を例示した説明図である。このメカニカルジョイントＪ２におけるナット１２,１２の開口端面１４,１４に対しては、前記第１半体２２および第２半体２４の夫々に形成した位置決め部Ｔ２,Ｔ２が対応的に接触し得るように設定されている。従って、この位置決め部Ｔ２,Ｔ２を前記メカニカルジョイントＪ２の開口端面１４,１４に整合させることで(図５(ａ),図６(ａ))、該メカニカルジョイントＪ２に対する第１凹面部２６および第２凹面部２８の適切な整合が図られ、当該メカニカルジョイントＪ２に対して前記第１半体２２および第２半体２４を正確に被着できる(図５(ｂ),図６(ｂ))。
【００２０】
なお、収容されるべき前記メカニカルジョイントＪ２に対して前記第１半体２２および第２半体２４を被着するに際しては、前記位置決め部Ｔ１,Ｔ１が当該メカニカルジョイントＪ２に接触して押圧される。従って位置決め部Ｔ１,Ｔ１は、圧潰的に変形して第１凹面部２６または第２凹面部２８の表面と略同一レベルまで押し潰される(図６(ｂ))。
【００２１】
このように、中間サイズの外形寸法を有するメカニカルジョイントＪ２も、前記第１半体２２および第２半体２４からなる実施例の配管カバー部材３０の内部に、径方向の位置決めは勿論、軸方向の位置決めも適切に図られた状態で安定的に収容される(図６(ｂ))。そして、第１半体２２および第２半体２４の接合面同士が密着的に接合し、かつ第１半体２２および第２半体２４の夫々の直管支持面部３６,３６がメカニカルジョイントＪ２に連結された各々の直管Ｐ,Ｐの外面に密着することで、実施例の配管カバー部材３０の内部に収容された当該メカニカルジョイントＪ２は外部から完全に隔離される。従って、(a)メカニカルジョイントＪ２の内部を流通する流体の保温、(b)メカニカルジョイントＪ２表面の結露防止、(c)メカニカルジョイントＪ２の破損防止、(d)人体が衝突した際の負傷防止(衝撃緩和)、等が好適に図られる。
【００２２】
(メカニカルジョイントＪ３を収容する場合)
図７および図８は、図２(ｃ)に例示した最大サイズの外形寸法を有するメカニカルジョイントＪ３に第１半体２２および第２半体２４を被着し、該メカニカルジョイントＪ３を実施例の配管カバー部材３０に収容する場合を例示した説明図である。このメカニカルジョイントＪ３におけるナット１２,１２の開口端面１４,１４に対しては、前記第１半体２２および第２半体２４の夫々に形成した位置決め部Ｔ３,Ｔ３が対応的に接触し得るように設定されている。従って、この位置決め部Ｔ３,Ｔ３を前記メカニカルジョイントＪ３の開口端面１４,１４に整合させることで(図７(ａ),図８(ａ))、該メカニカルジョイントＪ３に対する第１凹面部２６および第２凹面部２８の適切な整合が図られ、当該メカニカルジョイントＪ３に対して前記第１半体２２および第２半体２４を正確に被着できる(図７(ｂ),図８(ｂ))。
【００２３】
なお、収容されるべき前記メカニカルジョイントＪ３に対して前記第１半体２２および第２半体２４を被着するに際しては、前記位置決め部Ｔ１,Ｔ１および位置決め部Ｔ２,Ｔ２が当該メカニカルジョイントＪ３に接触して押圧される。従って、位置決め部Ｔ１,Ｔ１および位置決め部Ｔ２,Ｔ２は、圧潰的に変形して第１凹面部２６または第２凹面部２８の表面と略同一レベルまで押し潰される(図８(ｂ))。
【００２４】
このように、最大サイズの外形寸法を有するメカニカルジョイントＪ３であっても、前記第１半体２２および第２半体２４からなる実施例の配管カバー部材３０の内部に、径方向の位置決めは勿論、軸方向の位置決めも適切に図られた状態で安定的に収容される(図８(ｂ))。そして、第１半体２２および第２半体２４の接合面同士が密着的に接合し、かつ第１半体２２および第２半体２４の夫々の直管支持面部３６,３６がメカニカルジョイントＪ３に連結された各々の直管Ｐ,Ｐの外面に密着することで、実施例の配管カバー部材３０の内部に収容された当該メカニカルジョイントＪ３は外部から完全に隔離される。従って、(a)メカニカルジョイントＪ３の内部を流通する流体の保温、(b)メカニカルジョイントＪ３表面の結露防止、(c)メカニカルジョイントＪ３の破損防止、(d)人体が衝突した際の負傷防止(衝撃緩和)、等が好適に図られる。
【００２５】
前述した如く、本実施例に係る配管カバー部材３０では、第１半体２２の第１凹面部２６および第２半体２４の第２凹面部２８を、形状および外形寸法が僅かずつ異なる前記３種類のメカニカルジョイントＪ１,Ｊ２,Ｊ３の何れにも整合し得る形状とすると共に、これら第１凹面部２６および第２凹面部２８のナット支持面部３４の所要位置に、前記３種類のメカニカルジョイントＪ１,Ｊ２,Ｊ３の開口端面１４に対応的に接触し得る位置決め部Ｔ１,Ｔ２,Ｔ３を設けた。従って、収容されるべきメカニカルジョイントＪ１,Ｊ２,Ｊ３に対応する位置決め部Ｔ１,Ｔ２,Ｔ３を、当該メカニカルジョイントＪ１,Ｊ２,Ｊ３の開口端面１４に整合させることで、各々のメカニカルジョイントＪ１,Ｊ２,Ｊ３に対して第１半体２２および第２半体２４を好適に被着でき、これにより当該メカニカルジョイントＪ１,Ｊ２,Ｊ３をこれら第１半体２２および第２半体２４の内部に、径方向の位置決めは勿論、軸方向の位置決めも適切に図られた状態で安定的に収容することが可能となる。
【００２６】
これにより、３種類のメカニカルジョイントＪ１,Ｊ２,Ｊ３に対して単一の配管カバー部材３０だけを製造すればよいので、従来の如く３種類の配管カバー部材を各々製造する場合と比較すると、金型製作費用等の大幅な削減に伴って製造コストの低減が可能となり、低価格で供給し得るようになる。また、配管カバー部材３０が１種類だけなので、種類が少なくなって生産管理や在庫管理等の簡素化および合理化を図ることも可能となる。
【００２７】
なお前記実施例では、前記位置決め部Ｔ１,Ｔ２,Ｔ３の形成態様に関し、夫々の位置決め部Ｔ１,Ｔ２,Ｔ３の端部分を、第１凹面部２６および第２凹面部２８の周方向へ適宜オーバーラップさせた位置に形成した場合を例示した。しかしながら各々の位置決め部Ｔ１,Ｔ２,Ｔ３は、各々の形成位置等の制約がなければ、周方向へオーバーラップしないように形成してもよい。位置決め部Ｔ１,Ｔ２,Ｔ３をこのように形成した場合には、例えば位置決め部Ｔ１が圧潰的に変形した際にこれが隣接する位置決め部Ｔ２に影響を及ぼし、該位置決め部Ｔ２が変形してしまう不都合を確実に回避し得る利点がある。
【００２８】
そして実施例の配管カバー部材３０では、ナット支持面部３４と直管支持面部３６との境界部分に位置する端面を、更に位置決め部Ｔとして機能させることも可能である。この場合には、前記メカニカルジョイントＪ３より更に大きな外形寸法を有するメカニカルジョイントＪに対応させることが可能となる。
【００２９】
また前記実施例では、形状および外形寸法が僅かずつ異なる３種類のメカニカルジョイントＪ１,Ｊ２,Ｊ３に対応可能とした第１半体２２および第２半体２４とからなる配管カバー部材３０を例示した。しかし、前記第１凹面部２６および第２凹面部２８の形状や、前記位置決め部Ｔの形成位置および形成数を適切に設定することにより、３種類以上であるＮ種類のメカニカルジョイントＪ１,Ｊ２,Ｊ３・・・Ｊｎにも対応可能となる。
【００３０】
更に前記実施例では、前記第１半体２２および第２半体２４を別体に形成した配管カバー部材３０を例示したが、これら第１半体２２および第２半体２４は一体に形成したものでもよい。すなわち、夫々の一端縁同士を連設した開放状態で第１半体２２および第２半体２４を一体的に形成したもとで、例えば第１半体２２の第１凹面部２６を前記メカニカルジョイントＪ１,Ｊ２,Ｊ３の一方の外側面に整合させたもとで、第２半体２４を該第１半体２２に対して折り返し、該第２半体２４の第２凹面部２８を該メカニカルジョイントＪ１,Ｊ２,Ｊ３の他方の外側面に整合させれば、これら第１半体２２および第２半体２４の内部に当該メカニカルジョイントＪ１,Ｊ２,Ｊ３を収容することが可能である。
【００３１】
また実施例では、配管ジョイントとしてＬ形のメカニカルジョイントＪ(Ｊ１,Ｊ２,Ｊ３)を例示したが、本願の配管カバー部材は、これ以外のＩ形、Ｔ形、Ｙ形等の種々のメカニカルジョイントにも採用可能である。また配管ジョイントは、実施例に例示のメカニカルジョイントに限定されるものではなく、フランジ接合タイプのジョイント等も対象とされる。
【００３２】
【発明の効果】
以上説明した如く、本発明に係る配管カバー部材によれば、第１半体の第１凹面部および第２半体の第２凹面部を、形状および外形寸法が僅かずつ異なる複数種類の配管ジョイントの何れにも整合し得る形状とすると共に、これら第１凹面部および第２凹面部の所要位置に、前記複数種類の配管ジョイントの開口端面に対応的に接触し得る位置決め部を、該配管ジョイントの種類数だけ設けた。従って、収容されるべき配管ジョイントに対応する位置決め部を、この配管ジョイントの開口端面に整合させることで、該配管ジョイントに対して第１半体および第２半体を好適に被着でき、これにより当該配管ジョイントをこれら第１半体および第２半体の内部に安定的に収容することが可能となる利点がある。
従って、複数種類の配管ジョイントに対して単一の配管カバー部材だけを製造すればよいので、従来の如く複数種類の夫々に専用の配管カバー部材を製造する場合と比較すると、製造コストの大幅な低減が可能となる有益な効果を奏する。また、配管カバー部材が１種類だけなので、種類が少なくなって生産管理および在庫管理等の簡素化および合理化を図り得る等の利点もある。

For example, FIG. 9 shows a stainless steel mechanical joint J which is an L-shaped piping joint bent at 90 degrees, straight pipes P and P connected to the mechanical joint J, and an outer side of the mechanical joint J. It is the schematic perspective view which illustrated the piping cover member 20 made. The mechanical joint J is screwed to the main body 10 in order to connect the straight tube P and P to the respective open ends of the main body 10 and a bent cylindrical main body 10 formed in a substantially L shape. It consists of nuts 12 and 12. The pipe cover member 20 is made of a material having elasticity and flexibility, such as polyethylene foam, for example, and is a first concave surface that is aligned with one outer surface (lower surface in the drawing) of the L-shaped mechanical joint J described above. A first half 22 having a recessed portion 26 and a second concave surface portion 28 formed separately from the first half 22 and aligned with the other outer surface (the upper surface in the drawing) of the mechanical joint J are recessed.

[Problems to be solved by the invention]
By the way, even if the mechanical joint J is an L-shaped type that connects the straight pipes P, P having the same diameter, the shape and size are often slightly different for each manufacturer. Specifically, the bending degree and extension length of the main body 10 and the outer shape and length of the nut 12 are slightly different. For this reason, a plurality of types of piping composed of the first half 22 and the second half 24 in which the first concave surface portion 26 and the second concave surface portion 28 having a shape corresponding to each of the mechanical joints J that are put into practical use are provided. The actual condition is that the cover member 20 is manufactured in advance, and the pipe cover member 20 corresponding to the mechanical joint J to be accommodated is selected and used. Therefore, (1) it is necessary to prepare a molding die for molding each pipe cover member 20, which increases the manufacturing cost and increases the product price, and (2) increases the types of pipe cover members. Therefore, problems such as complicated production management and inventory management are inherent.
[0006]

DETAILED DESCRIPTION OF THE INVENTION
Next, a preferred embodiment of the piping cover member according to the present invention will be described below with reference to the accompanying drawings. Here, in this embodiment, the L-type mechanical joint illustrated in FIG. 9 is illustrated as a piping joint, and a piping cover member that is attached to the mechanical joint and accommodates the mechanical joint therein will be described. . Therefore, the same members and portions as those already shown in FIG. 9 will be described with the same reference numerals.
[0009]
FIG. 1 is a schematic perspective view showing a pipe cover member 30 according to a preferred embodiment of the present invention before being attached to a mechanical joint J. FIG. The piping cover member 30 of the present embodiment includes a first half 22 having a first concave surface portion 26 that is aligned with one outer surface (lower surface in the drawing) of an L-shaped mechanical joint J bent at approximately 90 degrees. The second half body 24 is formed separately from the first half body 22 and has a second concave surface portion 28 that is aligned with the other outer surface (upper surface in the drawing) of the mechanical joint J. Yes. The first half 22 and the second half 24 are attached to the mechanical joint J by aligning the first concave surface portion 26 and the second concave surface portion 28 with the outer surface of the mechanical joint J, respectively. Thus, the mechanical joint J can be accommodated in the first half 22 and the second half 24.
[0010]
In the piping cover member 30 of the embodiment, a plurality of types of mechanical joints having slightly different shapes and outer dimensions, specifically, the three types of mechanical joints J (J1, J2) shown in FIGS. , J3) can be stably accommodated in the first half 22 and the second half 24. These three types are all L-shaped types that connect the straight pipes P and P having the same diameter, but the bending mode (the degree of bending) of the main body 10 is slightly different, and the nuts 12 and 12 The outer shape and length L are different. Further, when the length dimension S between the center line of the right side opening portion of the main body 10 and the opening end surface 14 of the nut 12 screwed to the left side of the main body is used as a reference for the external dimensions, the mechanical joint J1 in FIG. (B) mechanical joint J2 has an intermediate size, and (c) mechanical joint J3 has a maximum size.
[0011]
In the pipe cover member 30 of the embodiment that can stably accommodate the three types of mechanical joints J1, J2, and J3, the first half body 22 and the second half body 24 have basically the same shape. For example, polyethylene foam formed by foaming polyethylene (PE), which is a material, is used as a material, and it has appropriate elasticity and flexibility. The first half 22 and the second half 24 are different from the first concave surface portion 26 and the second concave surface portion 28 in the three types of mechanical joints J1, J2, J3, which are slightly different in shape and external dimensions. Any of the mechanical joints J1, J2, and J3 can be accommodated by adopting a shape that can match any of the above.
[0012]
That is, the first concave surface portion 26 and the second concave surface portion 28 are provided in the main body support surface portion 32 that can be aligned with any main body 10 in each of the mechanical joints J1, J2, and J3 described above, and in the mechanical joints J1, J2, and J3. It consists of nut support surface portions 34, 34 that can be aligned with any nut 12, 12. However, the term “alignment” as used herein means that, in addition to a mode in which the first concave surface portion 26 and the second concave surface portion 28 are in close contact with the outer surfaces of the mechanical joints J1, J2, and J3, partially. A mode in which the contact is made in a state where a gap is defined, a mode in which the first concave surface portion 26 or the second concave surface portion 28 is in a state of being appropriately deformed, and the like are also included. Also, adjacent to the nut support surface portions 34, 34 are straight tube support surface portions 36, 36 that correspond to the straight tubes P, P connected to the mechanical joints J1, J2, J3. ing.
[0013]
Further, the required positions of the nut support surface portions 34, 34 in the first concave surface portion 26 and the second concave surface portion 28 correspond to the opening end surfaces 14 of the nuts 12, 12 in the respective mechanical joints J1, J2, J3. Positioning portions T (T1, T2, T3) that can come into contact are provided by the number of types of the mechanical joints J1, J2, J3. The positioning portion T1 corresponding to the mechanical joint J1, the positioning portion T2 corresponding to the mechanical joint J2, and the positioning portion T3 corresponding to the mechanical joint J3 are all protruded from the first concave surface portion 26 and the second concave surface portion 28. It is a rib-shaped protrusion. Further, since the first half 22 and the second half 24 have elasticity and flexibility as described above, the positioning portions T1, T2, T3 also have appropriate elasticity and flexibility. Thus, the positioning portions T1, T2, and T3 are easily deformed in the radial direction of the pipe cover member 30 (vertical direction in FIG. 4). As a result, as will be described later, when the first half 22 and the second half 24 are attached to the mechanical joints J1, J2, and J3 to be accommodated, they contact the mechanical joints J1, J2, and J3. The positioning portions T1, T2, and T3 that are pressed are deformed in a crushed manner and are crushed to the same level as the surface of the first concave surface portion 26 or the second concave surface portion 28. However, the positioning portions T1, T2, and T3 are difficult to be deformed in the axial direction of the pipe cover member 30 (the left-right direction in FIG. 4), so-called flexural or shear deformation.
[0014]
The first half 22 and the second half 24 include inner foam layers 22A, 24A that directly contact the mechanical joints J1, J2, J3 and the straight pipes P, P, and the inner foam layers 22A, 24A. The outer and inner foam layers 22B and 24B are formed outside and exposed to the outside. That is, the inner joint layers 22A and 24A that are in direct contact with the mechanical joints J1, J2, and J3 and the straight pipes P and P that can be heated by the fluid temperature are made of polyethylene foam having excellent heat resistance. The outer foam layers 22B and 24B that may be exposed to the outside air, direct sunlight, wind and rain, etc. are made of polyethylene foam having excellent heat insulation and weather resistance.
[0015]
In addition, rib-shaped projecting pieces 38 and 38 project from the main body support surface portion 32 of the first concave surface portion 26 and the second concave surface portion 28. The rib-like projecting pieces 38, 38 do not have a function of positioning the mechanical joints J1, J2, J3 with respect to the first half 22 and the second half 24, but the main bodies of the mechanical joints J1, J2, J3. The outer surface 10 is elastically supported and functions to stabilize the main body 10. That is, due to the presence of the rib-like protrusions 38, 38, the main body 10 of the mechanical joints J1, J2, J3 is stable even if it does not completely contact the main body support surface portion 32 of the first concave surface portion 26 or the second concave surface portion 28. To become consistent.
[0016]

[0018]
In other words, the mechanical joint J1 having the smallest outer dimension is positioned not only in the radial direction but also in the axial direction inside the pipe cover member 30 of the embodiment including the first half 22 and the second half 24. The positioning is stably accommodated in a properly designed state (FIG. 4B). The joining surfaces of the first half 22 and the second half 24 are tightly joined to each other, and the straight pipe support surface portions 36, 36 of the first half 22 and the second half 24 are mechanical joints J1.

[0019]
(When housing mechanical joint J2)
FIGS. 5 and 6 show that the first half 22 and the second half 24 are attached to the mechanical joint J2 having the intermediate size illustrated in FIG. 2B, and the mechanical joint J2 is attached to the mechanical joint J2. FIG. 6 is an explanatory diagram illustrating the case of housing in a piping cover member 30. Positioning portions T2 and T2 formed in the first half 22 and the second half 24 can be correspondingly brought into contact with the open end faces 14 and 14 of the nuts 12 and 12 in the mechanical joint J2. Is set to Therefore, by aligning the positioning portions T2 and T2 with the opening end surfaces 14 and 14 of the mechanical joint J2 (FIGS. 5A and 6A), the first concave surface portion 26 and the first The two concave surfaces 28 are properly aligned, and the first half 22 and the second half 24 can be accurately attached to the mechanical joint J2 (FIGS. 5B and 6B). .
[0020]
When the first half 22 and the second half 24 are attached to the mechanical joint J2 to be accommodated, the positioning portions T1 and T1 are pressed against the mechanical joint J2. . Accordingly, the positioning portions T1 and T1 are crushed and deformed to substantially the same level as the surface of the first concave surface portion 26 or the second concave surface portion 28 (FIG. 6B).
[0021]
As described above, the mechanical joint J2 having an intermediate size is also positioned in the axial direction in the pipe cover member 30 of the embodiment including the first half 22 and the second half 24, as well as in the axial direction. Is stably accommodated in a properly designed state (FIG. 6B). Then, the joint surfaces of the first half 22 and the second half 24 are tightly joined to each other, and the straight pipe support surface portions 36, 36 of the first half 22 and the second half 24 are mechanical joints J2. The mechanical joint J2 accommodated in the pipe cover member 30 of the embodiment is completely isolated from the outside by being in close contact with the outer surface of each of the straight pipes P, P connected to each other. Therefore, (a) keeping the fluid flowing inside the mechanical joint J2, (b) preventing condensation on the surface of the mechanical joint J2, (c) preventing damage to the mechanical joint J2, and (d) preventing injury when a human body collides ( (Impact relaxation) and the like are preferably achieved.
[0022]
(When housing mechanical joint J3)
7 and FIG. 8, the first half 22 and the second half 24 are attached to the mechanical joint J3 having the maximum size illustrated in FIG. 2C, and the mechanical joint J3 is attached to the mechanical joint J3 according to the embodiment. FIG. 6 is an explanatory diagram illustrating the case of housing in a piping cover member 30. Positioning portions T3 and T3 formed in the first half 22 and the second half 24 can contact the opening end faces 14 and 14 of the nuts 12 and 12 in the mechanical joint J3 in a corresponding manner. Is set to Therefore, by aligning the positioning portions T3 and T3 with the opening end surfaces 14 and 14 of the mechanical joint J3 (FIGS. 7A and 8A), the first concave surface portion 26 and the first The two concave surfaces 28 are appropriately aligned, and the first half 22 and the second half 24 can be accurately attached to the mechanical joint J3 (FIGS. 7B and 8B). .
[0023]
When the first half 22 and the second half 24 are attached to the mechanical joint J3 to be accommodated, the positioning portions T1, T1 and the positioning portions T2, T2 are attached to the mechanical joint J3. Pressed in contact. Therefore, the positioning portions T1 and T1 and the positioning portions T2 and T2 are crushed and deformed to substantially the same level as the surface of the first concave surface portion 26 or the second concave surface portion 28 (FIG. 8B).
[0024]
Thus, even in the mechanical joint J3 having the maximum outer dimension, positioning in the radial direction is, of course, inside the pipe cover member 30 of the embodiment including the first half 22 and the second half 24. The axial positioning is stably accommodated in a properly designed state (FIG. 8B). The joining surfaces of the first half 22 and the second half 24 are tightly joined, and the straight pipe support surface portions 36, 36 of the first half 22 and the second half 24 are mechanical joints J3. The mechanical joint J3 housed inside the pipe cover member 30 of the embodiment is completely isolated from the outside by being in close contact with the outer surface of each of the straight pipes P, P connected to the pipe. Therefore, (a) keeping the fluid flowing inside the mechanical joint J3, (b) preventing condensation on the surface of the mechanical joint J3, (c) preventing damage to the mechanical joint J3, and (d) preventing injury when a human body collides ( (Impact relaxation) and the like are preferably achieved.
[0025]
As described above, in the pipe cover member 30 according to the present embodiment, the first concave portion 26 of the first half 22 and the second concave portion 28 of the second half 24 are slightly different in shape and external dimensions. The three types of mechanical joints J 1, J 2, and J 3 have shapes that can be matched with any of the types of mechanical joints J 1, J 2, and J 3. , J2 and J3 are provided with positioning portions T1, T2 and T3 that can contact the opening end faces 14 correspondingly. Accordingly, by aligning the positioning portions T1, T2, T3 corresponding to the mechanical joints J1, J2, J3 to be accommodated with the opening end faces 14 of the mechanical joints J1, J2, J3, the respective mechanical joints J1, J2 , J3 can be suitably attached to the first half 22 and the second half 24, so that the mechanical joints J1, J2, J3 are placed inside the first half 22 and the second half 24, In addition to the radial positioning, the axial positioning can be stably accommodated in a properly designed state.
[0026]
As a result, only a single pipe cover member 30 needs to be manufactured for the three types of mechanical joints J1, J2, and J3. Manufacturing costs can be reduced along with a significant reduction in mold manufacturing costs and the like, and it can be supplied at a low price. Further, since there is only one type of piping cover member 30, the number of types is reduced, and it becomes possible to simplify and rationalize production management and inventory management.
[0027]
In the embodiment, with respect to the formation of the positioning portions T1, T2, and T3, the end portions of the positioning portions T1, T2, and T3 are appropriately overlaid in the circumferential direction of the first concave surface portion 26 and the second concave surface portion 28. The case where it formed in the lapped position was illustrated. However, each positioning portion T1, T2, T3 may be formed so as not to overlap in the circumferential direction unless there is a restriction on each forming position. When the positioning portions T1, T2, and T3 are formed in this way, for example, when the positioning portion T1 is crushed and deformed, this affects the adjacent positioning portion T2, and the positioning portion T2 is deformed. There is an advantage that can be surely avoided.
[0028]
In the piping cover member 30 of the embodiment, the end surface located at the boundary portion between the nut support surface portion 34 and the straight pipe support surface portion 36 can further function as the positioning portion T. In this case, it is possible to correspond to the mechanical joint J having a larger outer dimension than the mechanical joint J3.
[0029]
Moreover, in the said Example, the piping cover member 30 which consists of the 1st half body 22 and the 2nd half body 24 which can respond | correspond to three types of mechanical joints J1, J2, and J3 from which shape and external dimensions differ slightly was illustrated. . However, by appropriately setting the shape of the first concave surface portion 26 and the second concave surface portion 28 and the formation position and number of the positioning portions T, N types of mechanical joints J1, J2, J3... Jn can also be handled.
[0030]
Furthermore, in the said Example, although the piping cover member 30 which formed the said 1st half body 22 and the 2nd half body 24 in the different body was illustrated, these 1st half body 22 and the 2nd half body 24 were formed integrally. It may be a thing. That is, with the first half 22 and the second half 24 integrally formed in an open state in which the respective one end edges are connected to each other, for example, the first concave surface portion 26 of the first half 22 is placed on the mechanical side. The second half 24 is folded back with respect to the first half 22 while being aligned with one outer surface of the joints J1, J2, J3, and the second concave surface portion 28 of the second half 24 is moved to the mechanical joint. The mechanical joints J1, J2, and J3 can be accommodated in the first half 22 and the second half 24 if they are aligned with the other outer surface of J1, J2, and J3.
[0031]
In the embodiment, the L-shaped mechanical joint J (J1, J2, J3) is exemplified as the piping joint. However, the piping cover member of the present application is other various mechanical joints such as I-shaped, T-shaped and Y-shaped. It can also be adopted. The pipe joint is not limited to the mechanical joint illustrated in the embodiment, and a flange joint type joint or the like is also targeted.
[0032]
【The invention's effect】
As described above, according to the piping cover member of the present invention, the first concave portion of the first half and the second concave portion of the second half are a plurality of types of piping joints having slightly different shapes and external dimensions. And a positioning portion capable of correspondingly contacting the opening end surfaces of the plurality of types of pipe joints at the required positions of the first concave surface portion and the second concave surface portion. There were as many types as possible. Therefore, by aligning the positioning portion corresponding to the pipe joint to be accommodated with the opening end face of the pipe joint, the first half and the second half can be suitably attached to the pipe joint. Thus, there is an advantage that the pipe joint can be stably accommodated in the first half and the second half.
Therefore, since only a single piping cover member needs to be manufactured for a plurality of types of piping joints, the manufacturing cost is significantly higher than when a dedicated piping cover member is manufactured for each of a plurality of types as in the prior art. There is a beneficial effect that can be reduced. In addition, since there is only one type of piping cover member, there are advantages that the number of types is reduced and production management and inventory management can be simplified and rationalized.
