Description

【０００１】
【発明の属する技術分野】
この発明は目地部の構造に関し、主にＤＰＧやＭＰＧ等のガラススクリーンにおいて、隣接するガラス間のジョイント部（以下「目地部」という）の水密性と気密性を確保するために施工されるものである。
【０００２】
【従来の技術】
ガラススクリーン等における隣接するガラス間の目地部の水密性と気密性を確保する方法として、目地部に不定形のシーリング材を充填する方法が一般に知られている。
【０００３】
また、施工方法としては、目地部の周囲に特に障害となるようなものがなく、表側と裏側のいずれからでも施工可能な場合においては、一般に目地部の一方側にシーリング材の受けとなる治具を取り付けておき、反対側から目地部にシーリング材を充填する方法がとられている。
【０００４】
【発明が解決しようとする課題】
しかし、例えば図６に図示するように、ガラス１とガラス２との目地部３の裏側に、柱や梁などの障害物があって裏側に手が回らないような場合には、シーリング材４の施工がきわめて困難か、全くできない場合があった。
【０００５】
この発明は、以上の課題を解決するためになされたもので、特に目地部の一方側からのみでも施工を可能にした目地部の構造を提供することを目的とする。
【０００６】
【課題を解決するための手段】
請求項１記載の目地部の構造は、目地部の対向する両端面に第一の目地部材がそれぞれ取り付けられ、この第一の目地部材間に第二の目地部材が取り付けられてなる目地部の構造において、前記第一の目地部材に側方に開口する係合溝が設けられ、前記第二の目地部材に前記目地部を塞ぐフランジと前記係合溝に係合可能な係合突起がそれぞれ設けられ、前記目地部を塞ぐフランジとして第二の目地部材に前記目地部の表側を塞ぐ表フランジと前記目地部の裏側を塞ぐ裏フランジがそれぞれ設けられ、かつ前記第一の目地部材は弾性材から形成されてなることを特徴とするものである。
【０００７】
この場合、第一の目地部材間に第二の目地部材が側方から強く押し込まれた際の反発力（復元力）によって、第二の目地部材を第一の目地部材間に確実に固定することができ、また目地部をフランジが塞ぐことで目地部の水密性と気密性を確保することができる。
【０００８】
また、目地部に動きが生じても第一の目地部材と第二の目地部材がそれに追随変形することで、目地部材が破断したり剥離したりするようなことはなく、目地部の水密性と気密性を維持することができる。
【０００９】
さらに、施工に際しても、多少の寸法誤差、目地部材のしわやひずみ等は、目地部材を弾性材で形成することで簡単に吸収することができる。
【００１０】
請求項２記載の目地部の構造は、請求項１記載の目地部の構造において、目地部を塞ぐフランジとして前記目地部の表側を塞ぐ表フランジと裏側を塞ぐ裏フランジがそれぞれ設けられていることを特徴とするものである。

【００１２】
請求項２記載の目地部の構造は、請求項１記載の目地部の構造において、目地部を塞ぐフランジとして第一の目地部材に目地部の裏側を塞ぐ裏フランジが設けられていることを特徴とするものである。

【００１４】
請求項３記載の目地部の構造は、目地部の対向する両端面に第一の目地部材がそれぞれ取り付けられ、この第一の目地部材間に第二の目地部材が取り付けられてなる目地部の構造において、前記第一の目地部材に前記目地部の外側に突出する突出片が対向してそれぞれ設けられ、前記第二の目地部材に前記目地部を塞ぐフランジと前記突出片間に係合可能な係合突起がそれぞれ設けられ、かつ前記係合突起は弾性材から形成されてなることを特徴とするものである。
【００１５】
請求項４記載の目地部の構造は、請求項３記載の目地部の構造において、係合突起は中空に形成されてなることを特徴とするものである。
【００１６】
請求項５記載の目地部の構造は、目地部の対向する両端面に第一の目地部材がそれぞれ取り付けられ、この第一の目地部材間に第二の目地部材が取り付けられてなる目地部の構造において、前記第一の目地部材に前記目地部の外側に突出する突出片が対向してそれぞれ設けられ、前記突出片間に第三の目地部材が取り付けられており、前記第二の目地部材に前記目地部を塞ぐフランジと前記第三の目地部材に係合可能な係合突起が設けられ、かつ前記第三の目地部材は弾性材から形成されてなることを特徴とするものである。
【００１７】
請求項６記載の目地部の構造は、請求項５記載の目地部の構造において、第三の目地部材は断面ほぼ溝形状に形成されてなることを特徴とするものである。
【００１８】
請求項７記載の目地部の構造は、請求項１〜４のいずれかひとつに記載の目地部の構造において、第一の目地部材および／または第二の目地部材はゴムまたは合成樹脂から形成されてなることを特徴とするものである。
請求項８記載の目地部の構造は、請求項５または６記載の目地部の構造において、第一の目地部材、第二の目地部材および／または第三の目地部材はゴムまたは合成樹脂から形成されてなることを特徴とするものである。
【００１９】
【発明の実施の形態】
図１と図２は、この発明に係る目地部の構造の一例を示し、図においてガラス１とガラス２との目地部に一定幅の隙間が設けられ、この目地部３に第一の目地部材として目地部材５，５、第二の目地部材として目地部材６がそれぞれ取り付けられている。
【００２０】
目地部材５はガラス１の端面１ａとガラス２の端面２ａにそれぞれ取り付けられ、目地部材６は目地部材５，５間に取り付けられている。
【００２１】
目地部材５は固定部５ａと隆起部５ｂとから形成され、固定部５ａはガラス１および２（目地部３）の上下方向に連続し、かつ一定の厚さを有する板状に形成され、また固定部５ａの裏面側に凹溝または凹部５ｃが多数形成されている。
【００２２】
隆起部５ｂは固定部５ａの表面側に固定部５ａの長手方向に連続し、かつ一定の高さに隆起した状態に形成されている。また、隆起部５ｂには目地部３の外方向に開口する係合溝５ｄが固定部５ａの長手方向に連続して形成され、かつその開口端にフック５ｅが形成されている。
【００２３】
なお、目地部材５の固定部５ａ、隆起部５ｂ、凹溝または凹部５ｃおよびフック５ｅは耐候性にすぐれた合成ゴム等のゴムや合成樹脂などの弾性材から一体的に形成されている。
【００２４】
また、目地部材５は、ガラス１の端面１ａとガラス２の端面２ａにそれぞれ固定部５ａの裏面側を接着することにより取り付けられている。この場合、固定部５ａの裏面側に凹溝または凹部５ｃが多数形成されていることで、固定部５ａの裏面側に接着剤を充分に塗着することができるため、目地部材５をガラス１の端面１ａとガラス２の端面２ａにそれぞれ確実に接着することがでる。
【００２５】
一方、目地部材６は表フランジ６ａ、裏フランジ６ｂ、ウェブ６ｃおよび係合突起６ｄとから形成されている。表フランジ６ａと裏フランジ６ｂはそれぞれ目地部３の表側と裏側を塞ぐ幅を有し、かつガラス１および２（目地部３）の上下方向に連続して形成されている。
【００２６】
また、ウェブ６ｃは表フランジ６ａと裏フランジ６ｂ間にこれらと一体をなし、かつガラス１および２の上下方向に連続して形成されている。
【００２７】
さらに、係合突起６ｄ，６ｄはガラス１および２（目地部３）の上下方向に連続し、表フランジ６ａの内側部から目地３の内方に向かって斜めに突設され、さらに係合突起６ｄ，６ｄの先端にフック６ｅがそれぞれ形成されている。
【００２８】

【００２９】
また、このように形成された目地部材６は目地部材５，５間に目地部３の表側から強く押し込むことによって取り付けられている。この場合、目地部材６は目地部材５，５間に強く押し込まれることで、裏フランジ６ｂは変形してウェブ６ｃとともに目地部材５，５の隆起部５ｂ，５ｂ間を通過し、その後すぐ元の形状に復元して目地部３の裏側を塞ぎ、表フランジ６ａが目地部３の表側を塞ぐ。
【００３０】
また、係合突起６ｄ，６ｄが目地部材５，５の係合溝５ｄ，５ｄと係合することで目地部材６は目地部材５，５間に固定され、これによりガラス１と２間の目地部３の水密性と気密性が確保されている。
【００３１】
なお、この場合、係合溝５ｄの開口端に形成されたフック５ｅと係合突起６ｄのフック６ｅが係合していることで、係合突起６ｄが係合溝５ｄから簡単にはずれるようなことはない。
【００３２】
図３（ａ）〜（ｃ）は、この発明に係る目地部の構造の他の例を示し、図示するように目地部材５，５の裏側端部に裏フランジ５ｆ，５ｆがほぼ同一平面内で対向した状態にそれぞれ突設されている。また、目地部材６の裏側端部に裏フランジ６ｆが突設されている。そして、目地部材５，５間に目地部材６が押し込まれると同時に目地部材６の裏フランジ６ｆが裏フランジ５ｆ，５ｆ間の隙間を塞ぐことで目地部３の裏側が完全に塞がれている。
【００３３】
また、目地部材５，５の表側端部に係止部５ｇ，５ｇがそれぞれ突設され、この係止部５ｇ，５ｇに目地部材６の表フランジ６ａの両端が係合した状態で密着し、目地部３の外側が完全に塞がれている。これにより目地部３の水密性と気密性が確保されている。
【００３４】
図４（ａ）〜（ｃ）は、この発明に係る目地部の構造の他の一例を示し、図においてガラス１とガラス２との目地部３に一定幅の隙間が設けられ、この目地部３に第一の目地部材として目地部材７，７、第二の目地部材として目地部材８がそれぞれ取り付けられている。
【００３５】
目地部材７はガラス１とガラス２の端部（特にコーナ部）にそれぞれ取り付けられ、目地部材８は目地部材７，７間に取り付けられている。
【００３６】
また、目地部材７は固定部７ａと突出部７ｂとから形成され、固定部７ａはガラス１および２（目地部３）の上下方向に連続する断面ほぼＬ字状に形成され、固定部７ａの裏面には凹溝または凹部７ｃが多数形成されている。
【００３７】
突出部７ｂは固定部７ａのコーナ部から目地部３の外側にほぼ垂直な板状に突出し、かつ固定部７ａの長手方向に連続して形成されている。また、固定部７ａのコーナ部には突状部７ｄが固定部７ａの長手方向に連続して形成されている。

なお、目地部材７の固定部７ａ、突出部７ｂおよび突状部７ｄは耐候性にすぐれた合成ゴム等のゴムや合成樹脂などの弾性材から一体的に形成されている。また、目地部材７は、ガラス１とガラス２の端部（コーナ部）にそれぞれ固定部７ａの裏面側を接着することにより取り付けられている。
【００３９】
この場合、固定部７ａの裏面側に凹溝または凹部７ｃが多数形成されていることで、固定部７ａの裏面側に接着材を充分に塗着することができるため、目地部材７をガラス１とガラス２の端部にそれぞれ確実に接着することがでる。
【００４０】
一方、目地部材８は表フランジ８ａ、裏フランジ８ｂ、ウェブ８ｃおよび係合突起８ｄとから形成されている。表フランジ８ａと裏フランジ８ｂはそれぞれ目地部３の表側と裏側を塞ぐ幅を有し、かつガラス１および２の上下方向に連続して形成されている。
【００４１】
また、ウェブ８ｃは表フランジ８ａおよび裏フランジ８ｂと一体をなし、表フランジ８ａと裏フランジ８ｂ間にガラス１および２の上下方向に連続して形成されている。さらに、係合突起８ｄは内フランジ８ｂの側部に上下方向に連続し、、かつ円筒形の中空に形成されている。
【００４２】
なお、目地部材８の外フランジ８ａ、内フランジ８ｂ、ウェブ８ｃおよび係合突起８ｄは、目地部材７と同様に耐候性にすぐれた合成ゴム等のゴムや合成樹脂などの弾性材から一体的に形成され、特に係合突起８ｄはより弾力性を有する合成ゴムや合成樹脂などから形成されている。
【００４３】
このように形成された目地部材８は、係合突起８ｄが目地部材７の突出部７ｂ、７ｂ間に嵌合されていることで目地部３に固定されている。この場合、特に係合突起８ｄが弾力性を有する合成ゴムや合成樹脂などから形成され、さらに中空に形成されていることで、係合突起８ｄは弾力性に富み、これにより目地部材８は目地部３に確実に固定されている。
【００４４】
図５（ａ）〜（ｄ）は、同じくこの発明に係る目地部の構造の他の一例を示し、図においてガラス１とガラス２との目地部３に一定幅の隙間が設けられ、この目地部３に第一の目地部材として目地部材９，９、第二の目地部材として目地部材１０、そして第三の目地部材として目地部材１１がそれぞれ取り付けられている。
【００４５】
目地部材９はガラス１とガラス２の端部（コーナ部）にそれぞれ取り付けられ、目地部材１０は目地部材９，９間に取り付けられ、さらに目地部材１１は目地部材１０，１０間に取り付けられている。
【００４６】
目地部材９は固定部９ａと突出部９ｂとから形成され、固定部９ａはガラス１および２（目地部３）の上下方向に連続する断面ほぼＬ字状に形成され、その裏面には凹溝または凹部９ｃが多数形成されている。
【００４７】
突出部９ｂは固定部９ａのコーナ部から目地部３の外側にほぼ垂直な板状に突出し、かつ固定部９ａの長手方向に連続して形成されている。また、突出部９ｂの対向面は断面ほぼは鋸歯状に形成されている。さらに、固定部９ａのコーナ部には突状部９ｄが固定部９ａの長手方向に連続して形成されている。
【００４８】
なお、目地部材９の固定部９ａ、突出部９ｂおよび突状部９ｄは耐候性にすぐれた合成ゴム等のゴムや合成樹脂などの弾性材から一体的に形成されている。また、目地部材９は、ガラス１とガラス２の端部（コーナ部）にそれぞれ固定部９ａの裏面側を接着することにより取り付けられている。
【００４９】
この場合、固定部９ａの裏面側に凹溝または凹部９ｃが多数形成されていることで、固定部９ａの裏面側に接着剤を充分に塗着することができるため、目地部材９をガラス１とガラス２の端部にそれぞれ確実に固着することがでる。
【００５０】
目地部材１０は表フランジ１０ａ、裏フランジ１０ｂ、ウェブ１０ｃおよび係合突起１０ｄとから形成されている。表フランジ１０ａと裏フランジ１０ｂはそれぞれ目地部３の表側と裏側を塞ぐ幅を有し、かつガラス１および２の上下方向に連続して形成されている。
【００５１】
また、ウェブ１０ｃは表フランジ１０ａおよび裏フランジ１０ｂと一体をなし、表フランジ１０ａと裏フランジ１０ｂ間にガラス１および２（目地部３）の上下方向に連続して形成されている。さらに、係合突起１０ｄは裏フランジ１０ｂの側部に上下方向に連続して形成されている。
【００５２】
なお、目地部材１０の表フランジ１０ａ、裏フランジ１０ｂ、ウェブ１０ｃおよび係合突起１０ｄは、目地部材９と同様に耐候性にすぐれた合成ゴム等のゴムや合成樹脂などの弾性材から一体的に形成されている。
【００５３】
こうして形成された目地部材１０は目地部材９，９間に表側から裏内側に向けて挿入することにより取り付けられている。この場合、目地部材１０の係合突起１０ｄは目地部材１１に係合されている。
【００５４】
目地部材１１は目地部材１０側に開口する断面ほぼ溝形状に形成され、その両側の外側面は目地部材９の突出部９ｂの対向面に対応して断面ほぼ鋸歯状に形成されている。
【００５５】
そして、目地部材１１は目地部材９，９の突出部９ｂ，９ｂ間に嵌合されている。その際、双方の鋸歯が互いに係合し合っていることで、目地部材１１は突出部９ｂ，９ｂ間に強固に固定されている。また、目地部材１０の係合突起１０ｄが目地部材１１に係合していることで、目地部材１０は目地部材９，９間に固定されている。
【００５６】
なお、上記説明では、表側を屋外側、裏側を屋内側としたが、ここでいう表側と裏側は、単に目地部の一側面とその反対側を意味するものである。
【００５７】
【発明の効果】
この発明は以上説明したとおりであり、例えば請求項１記載の発明によれば、目地部の対向する両端面に第一の目地部材をそれぞれ取り付け、かつこの第一の目地部材間に第二の目地部材を取り付けてなる目地部の構造において、第一の目地部材に側方に開口する係合溝を設け、前記第二の目地部材に前記目地部を塞ぐフランジと前記係合溝に側方から係合可能な係合突起をそれぞれ設け、かつ前記第一の目地部材を弾性材から形成することで、第一の目地部材間に第二の目地部材を目地部の片方から強く押し込んで取り付けるだけで、目地部を容易に施工することができる。また、目地部を塞ぐフランジによって目地部の水密性と気密性を確保することができる。
