Description

【０００１】
【発明の属する技術分野】
本発明は、板ガラス保持部材に関し、特に、板ガラス体本体の外周縁に嵌め込まれる板ガラス保持部材に関する。
【０００２】
【従来の技術】
図１３は、第１の従来技術による板ガラス保持部材を備える板ガラス体の側面図である。
【０００３】
図１３に示すように、第１の従来技術による複層ガラス体１００は、複層ガラス体本体１１０と、複層ガラス体本体１１０の外周縁に嵌め込まれた複層ガラス保持部材１３１と、複層ガラス体本体１１０を複層ガラス保持部材１３１を介して支持する枠であるサッシ（不図示）とから成る。複層ガラス保持部材１３１は、複層ガラス体１００のサッシのチャンネル（不図示）内で複層ガラス体本体１１０を保持する。
【０００４】
複層ガラス保持部材１３１は、複層ガラス体本体１１０の底辺以外の３辺の外周縁に嵌め込まれる長尺状断面Ｕ字形の保持部１４０と、複層ガラス体本体１１０の底辺の外周縁をその両側で挟持する長尺状の一対の保持部１５０とから成る。一対の保持部１４０は、夫々断面Ｌ字形部材から成る。
【０００５】
保持部１４０は、複層ガラス体本体１１０の底辺の外周縁において、保持部１４０の端部１４０ａ，１４０ｂと保持部１５０の端部１５０ａ，１５０ｂとは、夫々接している。（例えば、非特許文献１参照）。
【０００６】
複層ガラス保持部材１３１は、一対の保持部１５０が、夫々断面Ｌ字形部材から成り、複層ガラス体本体１１０の底辺の外周縁をその両側で挟持するので、複層ガラス体１００は、その底辺において排水効率が良い。
【０００７】
図１４は、第２の従来技術による板ガラス保持部材を備える板ガラス体の側面図である。
【０００８】
図１４に示すように、第２の従来の複層ガラス体２００は、複層ガラス体本体２１０と、複層ガラス体本体２１０の外周縁に嵌め込まれた複層ガラス保持部材２３１と、複層ガラス体本体２１０を複層ガラス保持部材２３１を介して支持する枠であるサッシ（不図示）とから成る。複層ガラス保持部材２３１は、複層ガラス体２００のサッシのチャンネル（不図示）内で複層ガラス体本体２１０を保持する。
【０００９】
複層ガラス保持部材２３１は、複層ガラス体本体２１０の４辺の外周縁に嵌め込まれる長尺状断面Ｕ字形の保持部から成る。断面Ｕ字形の保持部は、断面Ｕ字形部材から成る。
【００１０】
複層ガラス保持部材２３１は、複層ガラス体本体２１０の上辺に対応する部分がその略中間で分割されて分割端面２３１ａ，２３１ｂが形成されており、分割端面２３１ａ，２３１ｂは、ガスケット２４０を介して夫々気密に対向されている。また、複層ガラス保持部材２３１は、複層ガラス体本体２１０の４辺に対応して部分的に分割されており、他の部分は接続されている（例えば、非特許文献２参照）。
【００１１】
複層ガラス保持部材２３１は、複層ガラス体本体２１０の４辺に対応する部分において、断面Ｕ字形部材から成るので、複層ガラス体本体２１０に取り付けやすく、また、複層ガラス体本体２１０の上辺に対応する部分の略中間において、分割端面２３１ａ，２３１ｂがガスケット２４０を介して夫々気密に対向されているので、複層ガラス体２００は気密性が良い。

【発明が解決しようとする課題】
しかしながら、第１の従来技術による複層ガラス体１００では、一対の保持部１５０が夫々断面Ｌ字形部材から成るので、複層ガラス体本体１１０に固定されておらず、複層ガラス体１００の組み立てが困難であった。
【００１４】
また、第２の従来技術による複層ガラス体２００では、複層ガラス保持部材１３２が複層ガラス体本体１１０の底辺に対応する部分も断面Ｕ字形部材から成るので、複層ガラス体本体１００は、その底辺において排水効率が悪かった。

【発明の実施の形態】
以下、本発明の実施の形態を図面を参照しながら説明する。
【００２６】
図１は、本発明の実施の形態に係る板ガラス保持部材を備える板ガラス体の断面斜視図である。
【００２７】
図１に示すように、板ガラス体としての複層ガラス体１は、複層ガラス体本体１０と、複層ガラス体本体１０の外周縁に嵌め込まれた複層ガラス保持部材３０と、複層ガラス体本体１０を複層ガラス保持部材３０を介して支持する図３で後述するサッシ２０（板ガラス支持枠）とから成る。複層ガラス保持部材３０は、複層ガラス体１のサッシ２０のチャンネル内で複層ガラス体本体１０を保持する。
【００２８】
図２は、図１における複層ガラス体本体１０の部分断面図である。
【００２９】
図２において、複層ガラス体本体１０は、対向する一対のガラス板１１，１２と、一対のガラス板１１，１２の間に中空層１４を画成するようにそれらの周縁部に配されたスペーサ１３と、各板ガラス１１，１２とスペーサ１３とを接着している一次シール１５と、複層ガラス体本体１０の外周縁で、板ガラス１１，１２、及びスペーサ１３により形成された空間に板ガラス１１，１２の各外周面と同じ高さまで充填されている二次シール材１６とを備える。一次シール材１５は、特に水分を透過しにくくするためにブチルゴム系のシール材から、二次シール材１６は、接着力の高いシリコン系又はポリサルファイド系のシール材から成る。
【００３０】
スペーサ１３は、断面が略矩形の角筒部材１３ａと、その角筒部材１３ａの内空部に充填された乾燥剤１３ｂとから成り、角筒部材１３ａには、中空層１４と連通するように、長手方向に沿って等間隔に複数の貫通孔１３ｃが形成されている。乾燥剤１３ｂは、中空層１４内の水分を貫通口１３ｃを介して吸収し、中空層１４内での結露を防止する。
【００３１】
図３は、図１におけるサッシ２０の構成を示す断面図である。
【００３２】
図３において、サッシ２０は、アルミニウム製の、複層ガラス保持部材３０が外周縁に嵌め込まれた複層ガラス体本体１０を収容するチャンネルが形成されたサッシ本体２１と、サッシ本体２１のチャンネル底部２２上に載置され、複層ガラス体本体１０を支持するセッティングブロック２３とから成る。
【００３３】
図４は、図１における複層ガラス体本体１０の側面図であり、複層ガラス体本体１０に複層ガラス保持部材３０が取り付けられた場合を示す。
【００３４】
複層ガラス保持部材３０は、図４に示すように、複層ガラス体本体１０の鉛直方向上端部１０ａ、及び水平方向各側端部１０ｃ，１０ｄ（底辺以外の３辺の外周縁）に嵌め込まれる長尺状断面Ｕ字形の略コ字形保持部３１（断面Ｕ字形の板ガラス保持部）と、複層ガラス体本体１０の鉛直方向下端部１０ｂ（底辺の外周縁）に嵌め込まれ、その外周縁をその両側で挟持する長尺状の一対の下端保持部３２（一対の板ガラス保持部）とを備える。略コ字形保持部３１は、複層ガラス体本体１０の上端部１０ａに嵌め込まれる上端保持部４０と、側端部１０ｃ，１０ｄに嵌め込まれる長尺状の一対の側端保持部５０とから成る。
【００３５】
図５は、図４における略コ字形保持部３１の形状を示す部分断面図であり、図５（ａ）は、上端保持部４０の斜視図であり、図５（ｂ）は、図５（ａ）の線Ｖｂ−Ｖｂに沿う断面図である。
【００３６】
略コ字形保持部３１の上端保持部４０は、図５（ａ），（ｂ）に示すように、底部４４と側部４５とから成ると共に、複層ガラス体本体１０の上端縁部を収容し得る溝４３が形成されており、且つサッシ２０のチャンネル内に嵌め込まれ得る外形を有する断面略Ｕ字形の外側軟質部４１と、外側軟質部４１の両側部上縁と各下縁部で夫々接続されていると共に、収容される複層ガラス体本体１０の上端縁部を挟持し得る外形を有する一対の内側軟質部４２とから成る。軟質部４１，４２は、ショア硬度６０〜７５度程度の塩化ビニル樹脂製又はエラストマー系樹脂製である。
【００３７】
外側軟質部４１は、複層ガラス体本体１０と複層ガラス保持部材３０の間から侵入した水を逃がすための複数の水抜き孔４６を有し、水抜き孔４６は底部４４に長手方向に沿って等間隔で形成されている。
【００３８】
一対の内側軟質部４２は、複層ガラス体本体１０に対称に配置されており、以下の説明では、板ガラス１１側の内側軟質部４２に着目して説明する。板ガラス１２側の内側軟質部４２も同様である。
【００３９】
内側軟質部４２は、その上縁に、板ガラス１１の外側面との間を密閉すべく内側に突出したシール片部４７と、サッシ２０のチャンネルの一縁部に対して係止自在に外側に突出した弾性張出係止部４８と、その内側面に外側軟質部４１の底部４４に向かって斜めに突出した挟持片部４９とから成る。
【００４０】
一対の挟持片部４９は、その先端部各々の間隔寸法が複層ガラス体本体１０の厚さ寸法より小さく設定されており、複層ガラス体本体１０が溝４３に挿入される際に弾性的に撓んで、この撓みにより発生する板ガラス１１，１２の各外側面に対する摩擦力によって複層ガラス体本体１０を挟持し、また、弾性張出係止部４７は、複層ガラス体本体１０の上端縁部に嵌め込まれた上端保持部４０がサッシ２０のサッシ本体２１に収容されたときに、サッシ２０の縁部に係合することにより、その上端縁部が上端保持部４０の溝４３内に嵌め込まれた複層ガラス体本体１０は、その上端面が底部４４上に接地されて、上端保持部４０によりその底部４４上で支持され、且つ挟持片部４９によりその上端縁部が挟持されて、この上端保持部４０を介してサッシ２０により保持される（図９（ａ））。
【００４１】
図６は、図４における側端保持部５０の形状を示す部分図であり、図６（ａ）は、側端保持部５０の斜視図であり、図６（ｂ）は、図６（ａ）の側端保持部５０の上面図である。
【００４２】
側端保持部５０は、図６（ａ），（ｂ）に示すように、図５（ａ），（ｂ）の上端保持部４０と断面が同一形状で且つ同一サイズの長尺部５１と、長尺部５１の一対の内側軟質部４２端（両側部端）と接続されていると共に一対の内側軟質部４２と直交して設けられ、且つ複層ガラス体本体１０の下端部１０ｂ側の端部に形成されたＵ字形部材５２とから成る。各Ｕ字形部材５２は、図４に示すように、下端保持部３２に対向されていると共に、断面形状が下端保持部３２と同じであり、長尺部５１が複層ガラス体本体１０の側端部１０ｃ又は側端部１０ｄに嵌め込まれたときに複層ガラス体本体１０の下端部１０ｂに嵌め込まれて、複層ガラス体本体１０において、長尺部５１が上端部１０ａ方向に移動しないように側端保持部５０を固定する。
【００４３】
Ｕ字形部材５２は、その断面形状及び断面のサイズが図５（ｂ）の上端保持部４０と同一で、下端保持部３２の長手方向における長さが、例えば３ｍｍである。Ｕ字形部材５２は、底部５６と側部５７とから成ると共に、複層ガラス体本体１０の下端縁部を収容し得る溝５５が形成されており、且つサッシ２０のチャンネル内に嵌め込まれ得る外形を有する断面略Ｕ字形の外側軟質部５３と、外側軟質部５３の両側部上縁と各下縁部で夫々接続されていると共に、収容される複層ガラス体本体１０の下端縁部を挟持し得る外形を有する一対の内側軟質部５４とから成る。軟質部５３，５４は、ショア硬度６０〜７５度程度の塩化ビニル樹脂製又はエラストマー系樹脂製である。
【００４４】
一対の内側軟質部５４は、複層ガラス体本体１０に対称に配置されており、以下の説明では、板ガラス１１側の内側軟質部５４に着目して説明する。板ガラス１２側の内側軟質部５４も同様である。
【００４５】
内側軟質部５４は、その上縁に、板ガラス１１の外側面との間を密閉すべく内側に突出したシール片部５８と、サッシ２０のチャンネルの一縁部に対して係止自在に外側に突出した弾性張出係止部５９と、その内側面に外側軟質部５３の底部５６に向かって斜めに突出した挟持片部６０とから成る。
【００４６】
一対の挟持片部６０は、その先端部各々の間隔寸法が複層ガラス体本体１０の厚さ寸法より小さく設定されており、複層ガラス体本体１０の下端縁部が溝５５に挿入される際に弾性的に撓んで、この撓みにより発生する板ガラス１１，１２の各外側面に対する摩擦力によって複層ガラス体本体１０を挟持し、また、底部５６は、複層ガラス体本体１０の下端部１０ｂと接し、Ｕ字形部材５２は、長尺部５１が複層ガラス体本体１０の側端縁部に嵌め込まれたときに、複層ガラス体本体１０において、側端保持部５０が上端部１０ａ方向に移動しないように側端保持部５０を固定する（図９（ｂ））。
【００４７】
側端保持部５０において、互いに直交している内側軟質部４２，５４は互いに接続しており、具体的には、シール片部４７とシール片部５８とが接続していると共に、弾性張出係止部４８と弾性張出係止部５９とが接続している。
【００４８】
略コ字形保持部３１において、上端保持部４０と側端保持部５０とは、互いに直交しており、上端保持部４０の内側軟質部４２のシール片部４７及び弾性張出係止部４８と、側端保持部５０における長尺部５１の内側軟質部４２のシール片部４７及び弾性張出係止部４８とがそれぞれ互いに接続している。
【００４９】
図７は、略コ字形保持部３１の作成方法の一部を説明するために用いられる図４における略コ字形保持部３１の部分側面図である。
【００５０】
略コ字形保持部３１は、例えば、形状、構成、及び断面サイズが上端保持部４０と同一で、ショア硬度６０〜７５度程度の塩化ビニル樹脂製又はエラストマー系樹脂製の所定の長手方向長さの母材７００から以下のように作成される。母材７００は、外側軟質部４１０及び内側軟質部４２０から成る。
【００５１】
図７において、まず、上端保持部４０の長手方向長さ間隔で母材７００の外側軟質部４１０を切断して上端保持部４０の両側部自由端部Ｆ₁を形成し、次いで、上端保持部４０の両端の切断面から長尺部５１の長手方向長さに相当する位置で母材７００の外側軟質部４１０を切断して一対の長尺部５１の片側部両自由端部Ｆ₂を形成し、更に、長尺部５１の一端の切断面からＵ字形部材５２の長さに相当する位置で夫々母材７００の外側軟質部４１０を切断してＵ字形部材５２を形成する（図７（ａ））。次いで、上端保持部４０の両側部自由端部Ｆ₁で折り曲げることにより上端保持部４０に対して長尺部５１を夫々直交させ、長尺部５１の片側部両自由端部Ｆ₂（Ｕ字形部材５２の両側部自由端部）で折り曲げることにより長尺部５１に対してＵ字形部材５２をそれぞれ直交させる（図７（ｂ））。なお、これらの直交は、それぞれガラス体本体１０に取り付けながら実行される。これにより、略コ字形保持部３１を容易に作成してガラス体本体１０に取り付けることができ、もって複層ガラス体１の組み立てを容易にすることができる。
【００５２】
図８は、図４における下端保持部３２の形状を示す断面図であり、図８（ａ）は、下端保持部３２の形状を示す断面図であり、図８（ｂ）は、図８（ａ）の線VIIIｂ−VIIIｂに沿う断面図である。
【００５３】
下端保持部３２は、図８（ａ），（ｂ）に示すように、夫々断面Ｌ字形部材から成り、図５（ａ），（ｂ）の略コ字形保持部３１における上端保持部４０をその長手方向に分割した形状と略同じ形状であり、底部７３と側部７４とから成ると共に、サッシ２０のチャンネル内に嵌め込まれ得る外形を有する断面略Ｌ字形の硬質塩化ビニル製硬質部材７１と、硬質部材７１の側部７３上縁に各下縁部で夫々固定された塩化ビニル樹脂製又はエラストマー系樹脂製の軟質部材７２と、硬質部材７１の底部７３の内面に一方の面が貼着されており、他方の面が複層ガラス体本体１０の各表面と粘着される両面テープ７５（固定部材）とから成る。なお、この両面テープ７５は、硬質部材７１の底部７３の内面に部分的にも全体的にも貼着される。また、両面テープ７５に代えて接着剤等（固定部材）を使用してもよい。
【００５４】
軟質部材７２は、その上縁に、複層ガラス体本体１０の板ガラス１１の外側面との間を密閉すべく内側に突出したシール片部７６と、サッシ２０のチャンネルの一縁部に対して係止自在に外側に突出した弾性張出係止部７７と、その内側面に硬質部材７１の底部７３に向かって斜めに突出したショア硬度６０〜７５度程度の、塩化ビニル樹脂製又はエラストマー系樹脂製の挟持片部７８とから成る。
【００５５】
略コ字形保持部３１は、底部７３が複層ガラス体本体１０の下端部１０ｂに接した状態で、両面テープ７５により複層ガラス体本体１０の下端部１０ｂに貼着されて複層ガラス体本体１０において固定され、挟持片部７８が、弾性的に撓むことにより発生する板ガラス１１又は板ガラス１２の外側面に対する摩擦力によって複層ガラス体本体１０を挟持する。また、弾性張出係止部７７が、複層ガラス体本体１０の下端部１０ｂに取り付けられた一対の硬質部材７１がサッシ２０のサッシ本体２１に収容されたときに、サッシ２０の縁部に係合することにより、その下端部１０ｂに一対の略コ字形保持部３１が取り付けられた複層ガラス体本体１０は、その下端面１０ｂが底部７３上に接地されて、一対の略コ字形保持部３１によりその底部７３上で支持され、且つ挟持片部７８によりその下端部１０ｂが挟持されて、この一対の略コ字形保持部３１を介してサッシ２０により保持される（図９（ｃ））。
【００５６】
下端保持部３２は、複層ガラス体本体１０の下端縁部において、その側端面が、側端保持部５０の環状部材５２の側端面と気密に接するように、その長手方向長さが設定されている。
【００５７】
上述したように、図４の複層ガラス保持部材３０によれば、複層ガラス保持部材３０が取り付けられた複層ガラス体本体１０において、略コ字形保持部３１は、上端保持部４０と側端保持部５０の長尺部５１とが、各内側軟質部４２のシール片部４７及び弾性張出係止部４８とを介して互いに直交して接続しており、側端保持部５０は、長尺部５１とＵ字形部材５２とが、その内側軟質部４２のシール片部４７及び弾性張出係止部４８と、その軟質部材５４のシール片部５８及び弾性張出係止部５９とを介して直交して接続しており、下端保持部３２は、複層ガラス体本体１０の下端部１０ｂにおいて、その側端面が、側端保持部５０の環状部材５２の側端面と気密に接しているので、複層ガラス保持部材３０と複層ガラス体本体１０との間における気密性・水密性を良くすることができる。
【００５８】
加えて、複層ガラス体本体１０の下端部１０ｂに取り付けられたＵ字形部材５２は、複層ガラス体本体１０の側端部１０ｃ，ｄに取り付けられた長尺部５１が複層ガラス体本体１０の上端部１０ａ方向に移動しないように固定するので、複層ガラス体１の組み立てを容易にすることができると共に、長尺部５１が経年変化により縮むことを防止することができて、略コ字形保持部３１と下端保持部３２との間に隙間が生じることを防止でき、もって、複層ガラス保持部材３０と複層ガラス体本体１０との間の気密性・水密性を維持することができる。
【００５９】
また、図４の複層ガラス保持部材３０によれば、複層ガラス体本体１０において、Ｕ字形部材５２が複層ガラス体本体１０の下端部１０ｂに取り付けられることにより、側端保持部５０が固定され、また一対の下端保持部３２が両面テープ７５により複層ガラス体本体１０の下端縁部に固定されているので、複層ガラス保持部材３０が取り付けられた複層ガラス体本体１０をサッシ２０のサッシ本体２１に収容させるときに、一対の下端保持部３２及び側端保持部５０が移動して一対の下端保持部３２及び側端保持部５０の間に隙間が生じることを防止でき、もって複層ガラス１において複層ガラス保持部材３０と複層ガラス体本体１０との間の気密性・水密性の悪化を防止することができる。
【００６０】
更に、図４の複層ガラス保持部材３０によれば、Ｕ字形ではないＬ字形の一対の下端保持部３２が、複層ガラス体本体１０の下端部１０ｂに取り付けられているので、複層ガラス体１の下端部１０ｂにおける排水効率を良くすることができる。
【００６１】
図４の複層ガラス保持部材３０において、長尺部５１とＵ字形部材５２との接続、及び上端保持部４０と側端保持部５０との接続は、上記に限るものではない。例えば、長尺部５１及びＵ字形部材５２の互いに対応する端部、上端保持部４０及び長尺部５１の互いに対応する端部を長手方向に対して４５°に夫々切断した後に、各対応する切断面を接着材等の接着部材８０により接着して接続させてもよく（図１０（ａ））、また、長尺部５１及びＵ字形部材５２の互いに対応する端部、上端保持部４０及び長尺部５１の互いに対応する端部における内側軟質部４２，５４，７２及び外側軟質部４１，５３，硬質部材７１の側部４５，５７，７４を長手方向に対して４５°に夫々切断した後に、長尺部５１及びＵ字形部材５２を外側軟質部４１，５３の底部４４，５６において、上端保持部４０及び長尺部５１を外側軟質部４１の底部４４において折り曲げて、各対応する切断面を接着部材８０により接着して接続させてもよい（図１０（ｂ））。
【００６２】
上記実施の形態では、Ｕ字形部材５２をそれぞれガラス体本体１０に取り付ける際に（図７（ｂ））、各Ｕ字形部材５２が下端保持部３２に対向する（図４）としたが、図１１に示すように、Ｕ字形部材５２は、下端保持部３２の両端部を保持するようにガラス体本体１０に取り付けられてもよい。これにより、下端保持部３２の組み立てを容易にすることができると共に、Ｕ字形部材５２が下端保持部３２を支持することになるので、下端保持部３２の両面テープ７５が複層ガラス体１から剥離するのを防止することができ、好ましい。なお、Ｕ字形部材５２が下端保持部３２の両端部を保持するためには、Ｕ字形部材５２を下端保持部３２の両端部に重ね合わせてもよいし、Ｕ字形部材５２に下端保持部３２の両端部を潜り込ませてもよい。
【００６３】
