<P>PROBLEM TO BE SOLVED: To provide a gasket whose width dimensions can be adjusted while the gasket can be pushed in integrally. <P>SOLUTION: The gasket comprises: a surface member 10 that has specific width and thickness, is displaced to wide and narrow forms, comes into contact with an opening edge section 42 of a panel material fitting groove 41 of a frame material 40 and the surface of a panel material 50 for achieving airtightness and watertightness between the opening edge section 42 and the surface of the panel material 50; and first and second members 20 and 30 that are provided in one piece while being separated in a width direction on the rear surface 11 of the surface member 10. Then, the first member 20 has a mounting section 21 and a support section 22 and is mounted to a side section 43 of the panel member fitting groove 41. The second member 30 has a locking section 31 and locks the locking section 31 to the support section 22 of the first member 20, thus setting the surface member 10 to be in the narrow form. As a result, the width dimensions of the gasket 1 decrease, the lock section 31 is detached from the support section 22 by pressing the surface member 10, and the surface member 10 becomes the wide form for increasing the width dimensions of the gasket 1. <P>COPYRIGHT: (C)2004,JPO

Description

【０００１】
【発明の属する技術分野】
本発明は、ガラス、金属、樹脂等からなるパネル材を障子、窓、カーテンウオール等の枠材に嵌め込んで固定するのに用いるガスケットに関する。
【０００２】
【従来の技術】
枠材を方形枠状に連結し、その枠にガラスからなるパネル材を装着した障子が知られている。
この障子において、枠材のパネル材嵌合溝にパネル材をガスケットを用いて嵌め込んで固定するのが一般的である。
例えば、パネル材嵌合溝の一方の側部とパネル材の一方の表面との間及びパネル材嵌合溝の他方の側部とパネル材の他方の表面との間にガスケットをそれぞれ設けて固定すると共に、そのパネル材嵌合溝とパネル材との間を気密、水密している。
【０００３】
前述したパネル材の固定のやり方では、パネル材の厚さが薄いとガスケットによる気密性、水密性が低下し、パネル材の厚さが厚いとガスケットを押し込みづらく施工性が低下する。
このことを解消するガスケットが特開平１１−２５６９４１号公報に提案される。
このガスケットは、傾斜面を有する第１部材と傾斜した圧接面を有する第２部材を備え、第１部材の傾斜面と第２部材の圧接面を圧接する形態で、第１部材と第２部材の圧接位置をずらすことで幅寸法を調整できる。
前述したガスケットであれば、パネル材の厚さに応じてガスケットの幅寸法を調整し、気密性・水密性の向上、ガスケットを押し込み易く施工性を向上できる。
【０００４】
【発明が解決しようとする課題】
前述した従来のガスケットは、枠材のパネル材嵌合溝の側部とパネル材の表面との間に、第１部材と第２部材を連結した状態として同時に押し込むことができない。
このために、パネル材嵌合溝の側部とパネル材の表面の一方に第１部材又は第２部材を取付け、この後にパネル材をパネル材嵌合溝内に入れ、最後にパネル材嵌合溝の側部とパネル材の表面の他方とあらかじめ取付けた第１部材又は第２部材との間に、第２部材又は第１部材を押し込んでいるので、パネル材を枠材のパネル材嵌合溝に固定する作業が大変面倒である。
また、ガスケットは第１部材と第２部材の２部材から成るので、製造、運搬、保管が面倒である。
【０００５】
また、第１部材と第２部材との圧接位置によっては、第１部材の傾斜面と第２部材の圧接面の圧接部分がガスケット表面に露出することがあり、そのガスケット表面に露出した圧接部分に雨水等が毛細管現象で浸入する恐れがある。
このように、圧接部分に浸入した雨水等は冬季などに凍結してその圧接部分を損傷することがあるから、ガスケット寿命が短くなる。
【０００６】
本発明は前述の課題に鑑みなされたものであって、その目的は、幅寸法を調整できること、一体として押し込むことができパネル材を枠材のパネル材嵌合溝に固定する作業が容易であること、製造・運搬・保管が容易であること、ガスケット表面から雨水等がガスケット内部に浸入することがないこと、を満足したガスケットを提供することである。
【０００７】
【課題を解決するための手段】
第１の発明は、所定の幅と厚さを有し、広幅形態と狭幅形態に変位すると共に、枠材のパネル材嵌合溝の開口縁部とパネル材の表面に接して両者の間を気密・水密する表面部材と、
この表面部材の裏面に幅方向に離隔して一体に設けた第１部材と第２部材を備え、
前記第１部材は、前記パネル材嵌合溝の側部に取付けられる形態で、
前記第２部材は第１部材に保持されて表面部材を狭幅形態とし、かつ上下方向の力が作用すると第１部材に対して移動して表面部材が広幅形態となるようにしたことを特徴とするガスケットである。
【０００８】
第２の発明は、第１の発明において表面部材は幅方向にほぼ一直線状の広幅形態と、幅方向にほぼく字状の狭幅形態とに変位し、
第１部材は表面部材の幅方向一側寄りで、かつ支持部を備え、第２部材は表面部材の幅方向他側寄りで、かつ係止部を備え、この係止部を支持部に係止することで表面部材が前記狭幅形態となると共に、表面部材の幅方向他側寄りを押すと係止部が支持部から外れて表面部材が広幅形態となるようにしたガスケットである。
【０００９】
第３の発明は、第１又は第２の発明において第２部材はパネル材の表面に接すると共に、表面部材とともに幅方向に変位して表面部材の幅方向他端部と常にほぼ面一であるガスケットである。
【００１０】
【作　用】
第１の発明によれば、表面部材を広幅形態、狭幅形態とすることでガスケットの幅寸法を調整できる。
ガスケットは表面部材と第１部材と第２部材を備えていると共に、それらは一体であるから、枠材のパネル材嵌合溝の開口縁部、側部とパネル材の表面との間に一体として押し込むことができ、パネル材を枠材のパネル材嵌合溝に固定する作業が容易である。
しかも、ガスケットの製造、運搬、保管が容易である。
表面部材の表面がガスケットの表面であり、その表面部材の表面は幅方向に連続しているから、ガスケットの表面から雨水等がガスケット内部に浸入することがなく、ガスケットの寿命が長い。
【００１１】
第２の発明によれば、係止部を支持部に係止した狭幅形態で表面部材の幅方向一側寄りを押すことで第１部材をパネル材嵌合溝の側部に取付け支持し、パネル材の厚さが薄い場合には表面部材の幅方向他側寄りを押して係止部を支持部から外すことで表面部材を広幅形態としてパネル材表面に接することができる。
【００１２】
第３の発明によれば、表面部材とともに第２部材がパネル材の表面に接するので、気密性、水密性が向上する。
【００１３】
【発明の実施の形態】
図１に示すように、ガスケット１は、表面部材１０と、この表面部材１０の裏面１１に幅方向に離隔して一体的に設けられた第１部材２０、第２部材３０を備え、その表面部材１０の幅がガスケット１の幅寸法である。この実施の形態ではガスケット１はほぼＵ字形態であるが、それに限ることはない。
前記表面部材１０は図１に示す広幅形態と図２に示す狭幅形態に変位可能で、その表面１２は幅方向全長に亘って連続している。
この表面部材１０は図３に示すように、枠材４０におけるパネル材嵌合溝４１の開口縁部４２とパネル材５０の側面５０ａにそれぞれ接触、好ましくは圧接して両者の間を気密・水密する。
【００１４】
前記第１部材２０は、図３に示すように枠材４０におけるパネル材嵌合溝４１の側部４３（前述の開口縁部４２と連続した部分）に取付けられる。つまり、前記第１部材２０はガスケット１を前述のパネル材嵌合溝４１の側部４３に取付けて支持するものである。
【００１５】
前記第２部材３０は第１部材２０に表面部材１０の厚さ方向（以下上下方向という）に動かないように支持されると共に、所定の大きさの上下方向の力で上下方向に移動し、第２部材３０が第１部材２０に対して上下方向に動かないように支持されると図２に示すように表面部材１０が狭幅形態に保持され、第２部材３０が第１部材２０に対して上下方向に移動すると図１に示すように表面部材１０が広幅形態となる。
つまり、第２部材３０は第１部材２０に支持されて表面部材１０を狭幅形態とし、上下方向の力が作用すると移動して表面部材１０を広幅形態とする。
【００１６】
このようであるから、第２部材３０を第１部材２０に支持すると表面部材１０が図２に示すように狭幅形態となり、ガスケット１の幅寸法はＨ_２となる。
第２部材３０を上下方向の力で第１部材２０に対して移動（図示では下方に移動）すると表面部材１０が図１に示す広幅形態となり、ガスケット１の幅寸法がＨ_１（Ｈ_１＞Ｈ_２）となる。
【００１７】
次に、各部材の具体形状の一例を説明する。
前記表面部材１０は所定の幅Ｈと厚さＴを有する断面ほぼ長方形状で、外力の作用しない自由状態の時には図１に示すように幅方向に亘ってほぼ一直線の形態、つまり前述の広幅形態で、厚さ方向の外力によって折曲変位して図２に示すように幅方向にほぼく字状の形態、つまり前述の狭幅形態となる。
前記表面部材１０の表面１２は平坦面であり、雨水等が表面１２に沿ってスムーズに流れるようにしてある。なお、表面１２は平坦面に限ることはなく、凹凸などがあっても良い。
【００１８】
前記第１部材２０は表面部材１０の幅方向一側寄りに設けられ、取付部２１と支持部２２を備え、その取付部２１を前述のパネル材嵌合溝４１の側部４３に取付け支持され、支持部２２が第２部材３０と対向する。
この実施の形態では前記取付部２１は、幅方向一側面２３、この一側面２３よりも突出した突条２４、この突条２４を変形し易くする凹部２５、突条２４と連続し斜面となった押し込み面２６を有する形態で、前述したパネル材嵌合溝４１の側部４３とパネル材５０の表面５０ａとの間に押し込み易いと共に、その突条２４が図３に示すように前述の側部４３の下面と対向してガスケット１が抜け出し難くしている。
【００１９】
前記第１部材２０の幅方向他側面（第２部材３０と対向する面）２７には複数の突出片２８を上下方向（表面部材１０の厚さ方向）に間隔を置いて有し、この突出片２８の上面が前述の支持部２２を形成する。
つまり、この実施の形態では支持部２２が上下方向に間隔を置いて複数有する。
なお、取付部２１は前述の形態に限ることはない。
【００２０】
前記第２部材３０は表面部材１０の幅方向他端寄りに設けられ、その下端部は尖端形状で、前述の第１部材２０の支持部２２に係止する係止部３１としてある。この係止部３１は下向きの力で支持部２２から外れるようにしてある。例えば支持部２２（突出片２８の上面）を円弧形状としてある。
第２部材３０の幅方向一側面３２にはガイド突部３３が上下方向に間隔を置いて複数有し、このガイド突部３３は前記突出片２８の上面に接する斜面３３ａを有し、その斜面３３ａが突出片２８の上面に当たることで第２部材３０に幅方向他側に向かう力が作用し、係止部３１が支持部２２から外れ易くしてある。
【００２１】
前記第２部材３０は、この実施の形態では図３に示すように表面部材１０の幅方向他端部とほぼ面一、好ましくは面一で、パネル材５０の表面５０ａに接する、好ましくは圧接して気密・水密すると共に、表面部材１０ととも幅方向に変位して常時ほぼ面一、好ましくは面一であるが、これに限ることはない。
具体的には、前記第２部材３０の幅方向他側面（パネル材５０側の面）３４には複数の突片３５が上下方向に間隔を置いて一体に設けてあり、この突片３５がパネル材５０の表面５０ａに接触、好ましくは圧接する。
つまり、突片３５は表面部材１０の幅方向他端部とほぼ面一、好ましくは面一である。
【００２２】
前記第１部材２０は幅広で表面部材１０の幅方向には変位し難い形態である。前記表面部材１０の裏面１１には第１部材２０の幅方向他側面２７と連続して切欠部１３が形成され、表面部材２０はこの切欠部１３を境として第２部材３０側（幅方向他側部寄り）が屈曲変形し易くしてある。
前記第２部材３０は第１部材２０よりも幅が狭く、表面部材１０の幅方向に湾曲変形し易い。
この第２部材３０の幅方向一側面（第１部材２０と対向する面）３２における表面部材１０の裏面１１と連続した部分が切欠きされ、その切欠部３６で第２部材３０は表面部材１０に対して幅方向に変位し易い。
【００２３】
このようであるから、第２部材３０の係止部３１を図２に示すように第１部材２０の支持部２２（突出片２８の上面）に係止した時に第２部材３０は表面部材１０に対して幅方向に変位すると共に、第２部材３０自体が幅方向に湾曲変位し、突片３５と表面部材１０の幅方向他端部がほぼ面一の形態を維持する。
【００２４】
次に、パネル材５０の固定の仕方を図３に基づいて説明する。
枠材４０のパネル材嵌合溝４１における他方の側部４４の溝４５にガスケット４６を取付ける。このガスケット４６は従来のガスケットであるが、本発明のガスケット１を用いても良い。
パネル材嵌合溝４１の底部に設けたブロック５１にパネル材５０の端面を接し、このパネル材５０の他方の側面５０ａをガスケット４６に接する。
ガスケット１を図２に示す狭幅形態とし、表面部材１０の第１部材２０寄り部分（幅方向一側寄り部分）を押してパネル材５０の表面５０ａとパネル材嵌合溝４１の一方の側部４３との間にガスケット１を押し込む。
【００２５】
パネル材５０の厚さが厚い場合にはガスケット１を所定位置（第１部材２０がパネル材嵌合溝４１の側部４３に取付け完了する位置）まで押し込みすると、ガスケット１は図２に示す表面部材１０が狭幅形態のままで表面部材１０がパネル材嵌合溝４１の開口縁部４２とパネル材５０の表面５０ａとに接して両者の間を確実に気密・水密する。
パネル材５０の厚さが薄い場合には、ガスケット１を前述の所定位置まで押し込んでも表面部材１０がパネル材５０の表面５０ａに接しないので、表面部材１０の第２部材３０寄り部分（幅方向他側寄り部分）を押す。
これによって第２部材３０が第１部材２０に対して移動して表面部材１０は図１に示す広幅形態となるので、その表面部材１０がパネル材５０の表面５０ａに接（好ましくは圧接）する。
【００２６】
パネル材５０は図３に示すように複層ガラスであるが、これに限ることはなく、単板バラス、金属パネル、樹脂パネルでも良い。
また、図３においては本発明のガスケット１を室内側にのみ設けてあるが、室外側にのみ設けても良いことは勿論である。
【００２７】
前述の実施の形態では、ガスケット１を押し込んだ後に表面部材１０の幅を変えるようにしたが、ガスケット１を押し込む以前に表面部材１０の幅を変えることもできる。
【００２８】
【発明の効果】
請求項１に係る発明によれば、表面部材を広幅形態、狭幅形態とすることでガスケットの幅寸法を調整できる。
ガスケットは表面部材と第１部材と第２部材を備えていると共に、それらは一体であるから、枠材のパネル材嵌合溝の開口縁部、側部とパネル材の表面との間に一体として押し込むことができ、パネル材を枠材のパネル材嵌合溝に固定する作業が容易である。
しかも、ガスケットの製造、運搬、保管が容易である。
表面部材の表面がガスケットの表面であり、その表面部材の表面は幅方向に連続しているから、ガスケットの表面から雨水等がガスケット内部に浸入することがなく、ガスケットの寿命が長い。
【００２９】
請求項２に係る発明によれば、係止部を支持部に係止した狭幅形態で表面部材の幅方向一側寄りを押すことで第１部材をパネル材嵌合溝の側部に取付け支持し、パネル材の厚さが薄い場合には表面部材の幅方向他側寄りを押して係止部を支持部から外すことで表面部材を広幅形態としてパネル材表面に接することができる。
【００３０】
請求項３に係る発明によれば、表面部材とともに第２部材がパネル材の表面に接するので、気密性、水密性が向上する。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a gasket used to fit a panel material made of glass, metal, resin, or the like into a frame material such as a shoji, a window, a curtain wall, and the like to fix it.
[0002]
[Prior art]
2. Description of the Related Art A shoji screen is known in which frame materials are connected in a rectangular frame shape, and a panel material made of glass is mounted on the frame.
In this shoji, a panel material is generally fitted into a panel material fitting groove of a frame material using a gasket and fixed.
For example, a gasket is provided and fixed between one side of the panel material fitting groove and one surface of the panel material and between the other side of the panel material fitting groove and the other surface of the panel material. At the same time, the space between the panel material fitting groove and the panel material is airtight and watertight.
[0003]
In the above-described method of fixing the panel material, if the thickness of the panel material is small, the gas tightness and water tightness of the gasket decrease, and if the thickness of the panel material is large, the gasket is hard to be pushed in and the workability deteriorates.
A gasket that solves this problem is proposed in Japanese Patent Application Laid-Open No. H11-256941.
The gasket includes a first member having an inclined surface and a second member having an inclined pressing surface, and the first member and the second member are configured to press the inclined surface of the first member and the pressing surface of the second member. The width dimension can be adjusted by shifting the pressure contact position of.
In the case of the gasket described above, the width of the gasket is adjusted according to the thickness of the panel material, whereby the airtightness and watertightness can be improved, and the gasket can be easily pushed in, thereby improving the workability.
[0004]
[Problems to be solved by the invention]
In the conventional gasket described above, the first member and the second member cannot be simultaneously pushed into the state in which the first member and the second member are connected between the side of the panel material fitting groove of the frame material and the surface of the panel material.
For this purpose, the first member or the second member is attached to one of the side of the panel material fitting groove and the surface of the panel material, and thereafter the panel material is put into the panel material fitting groove. Since the second member or the first member is pushed between the side of the groove and the other of the surface of the panel member and the first member or the second member attached in advance, the panel member is fitted to the frame member by the panel member. The work of fixing in the groove is very troublesome.
Further, since the gasket is composed of two members, the first member and the second member, manufacture, transportation and storage are troublesome.
[0005]
Also, depending on the press-contact position between the first member and the second member, the press-contact portion between the inclined surface of the first member and the press-contact surface of the second member may be exposed on the gasket surface, and the press-contact portion exposed on the gasket surface. There is a danger that rainwater or the like may enter due to the capillary phenomenon.
As described above, rainwater or the like that has entered the press-contact portion may freeze in winter or the like and damage the press-contact portion, so that the life of the gasket is shortened.
[0006]
SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and has a purpose of being able to adjust a width dimension, to be able to be pushed in as a unit, and to easily fix a panel material to a panel material fitting groove of a frame material. An object of the present invention is to provide a gasket that satisfies that the manufacturing, transportation, and storage are easy, and that rainwater and the like do not enter the inside of the gasket from the gasket surface.
[0007]
[Means for Solving the Problems]
The first invention has a predetermined width and thickness, is displaced into a wide form and a narrow form, and is in contact with the opening edge of the panel material fitting groove of the frame material and the surface of the panel material and between the two. Airtight and watertight surface members,
A first member and a second member provided integrally on the back surface of the front member so as to be separated in the width direction;
The first member is configured to be attached to a side portion of the panel material fitting groove,
The second member is held by the first member to make the surface member narrow, and when a vertical force is applied, the second member moves with respect to the first member so that the surface member becomes wide. Is a gasket.
[0008]
According to a second aspect of the present invention, in the first aspect, the surface member is displaced into a wide form that is substantially straight in the width direction and a narrow form that is substantially rectangular in the width direction,
The first member is provided near the width direction one side of the surface member and has a support portion, and the second member is provided near the other width direction side of the surface member and is provided with a locking portion. The gasket is configured such that the surface member becomes the narrow form by stopping, and when the surface member is pushed toward the other side in the width direction, the locking portion is disengaged from the support part and the surface member becomes the wide form.
[0009]
According to a third aspect of the present invention, in the first or second aspect, the second member is in contact with the surface of the panel member, and is displaced in the width direction together with the surface member, and is always substantially flush with the other end in the width direction of the surface member. It is a gasket.
[0010]
[Operation]
According to the first aspect, the width dimension of the gasket can be adjusted by forming the surface member into a wide form or a narrow form.
The gasket includes a surface member, a first member, and a second member, and since they are integral, the gasket is integrally formed between the opening edge of the panel material fitting groove, the side portion, and the surface of the panel material. The work of fixing the panel material to the panel material fitting groove of the frame material is easy.
Moreover, the manufacture, transportation, and storage of the gasket are easy.
Since the surface of the surface member is the surface of the gasket, and the surface of the surface member is continuous in the width direction, rainwater or the like does not enter the inside of the gasket from the surface of the gasket, and the life of the gasket is long.
[0011]
According to the second invention, the first member is attached to and supported by the side of the panel material fitting groove by pushing the surface member toward one side in the width direction in a narrow form in which the locking portion is locked to the support portion. On the other hand, when the thickness of the panel member is thin, the surface member can be brought into a wide form to come into contact with the surface of the panel member by pushing the surface member toward the other side in the width direction to remove the locking portion from the support portion.
[0012]
According to the third aspect, since the second member is in contact with the surface of the panel member together with the surface member, the airtightness and the watertightness are improved.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
As shown in FIG. 1, the gasket 1 includes a surface member 10, and a first member 20 and a second member 30 integrally provided on a back surface 11 of the surface member 10 so as to be spaced apart in the width direction.

That is, the first member 20 supports the gasket 1 by attaching it to the side portion 43 of the above-described panel material fitting groove 41.
[0015]
The second member 30 is supported by the first member 20 so as not to move in a thickness direction of the surface member 10 (hereinafter, referred to as a vertical direction), and moves in a vertical direction with a predetermined vertical force, When the second member 30 is supported so as not to move in the vertical direction with respect to the first member 20, the surface member 10 is held in a narrow form as shown in FIG. On the other hand, when the surface member 10 is moved in the vertical direction, the surface member 10 has a wide form as shown in FIG.
In other words, the second member 30 is supported by the first member 20 to make the surface member 10 narrow, and when a vertical force is applied, it moves to make the surface member 10 wide.
[0016]
Since this be the case, the surface member 10 when supporting the second member 30 to the first member 20 becomes narrow form as shown in FIG. 2, the width of the gasket 1 becomes H _2.
When the second member 30 is moved with respect to the first member 20 with a vertical force (moves downward in the drawing), the surface member 10 becomes the wide form shown in FIG. 1, and the width dimension of the gasket 1 is H ₁ (H ₁ >). H ₂ ).

Next, an example of a specific shape of each member will be described.
The surface member 10 has a substantially rectangular cross section having a predetermined width H and a thickness T, and is substantially straight in the width direction as shown in FIG. Then, the sheet is bent and displaced by an external force in the thickness direction to have a substantially rectangular shape in the width direction as shown in FIG.
The surface 12 of the surface member 10 is a flat surface so that rainwater or the like flows smoothly along the surface 12. The surface 12 is not limited to a flat surface, but may have irregularities.
[0018]
The first member 20 is provided near one side in the width direction of the surface member 10 and includes a mounting portion 21 and a support portion 22. The mounting portion 21 is mounted and supported on the side portion 43 of the panel material fitting groove 41. , The support portion 22 faces the second member 30.
In this embodiment, the mounting portion 21 has one side surface 23 in the width direction, a ridge 24 protruding from the one side surface 23, a concave portion 25 for easily deforming the ridge 24, and a slope continuous with the ridge 24. In the form having the press-in surface 26, it is easy to press between the side portion 43 of the panel material fitting groove 41 and the surface 50a of the panel material 50, and the protruding ridges 24 as shown in FIG. The gasket 1 is hard to come out facing the lower surface of the portion 43.
[0019]
The other side surface (the surface facing the second member 30) 27 of the first member 20 in the width direction has a plurality of projecting pieces 28 spaced apart in the vertical direction (the thickness direction of the surface member 10). The upper surface of the piece 28 forms the support 22 described above.
That is, in this embodiment, a plurality of support portions 22 are provided at intervals in the vertical direction.
In addition, the mounting part 21 is not limited to the above-mentioned form.

The second member 30 is provided near the other end in the width direction of the surface member 10, and the lower end thereof has a pointed shape, and serves as a locking portion 31 that locks to the support portion 22 of the first member 20. The locking portion 31 is detached from the support portion 22 by a downward force. For example, the support portion 22 (the upper surface of the protruding piece 28) has an arc shape.
The one side surface 32 in the width direction of the second member 30 has a plurality of guide protrusions 33 at intervals in the vertical direction. The guide protrusions 33 have a slope 33 a that is in contact with the upper surface of the protrusion 28. The force of the second member 30 toward the other side in the width direction is applied to the second member 30 by the contact of the upper surface of the protruding piece 28 with the 33 a, so that the locking portion 31 is easily detached from the support portion 22.
[0021]
In this embodiment, the second member 30 is substantially flush, preferably flush with the other end in the width direction of the surface member 10 and is in contact with the surface 50a of the panel member 50, as shown in FIG. While being airtight and watertight, it is displaced in the width direction with the surface member 10 and is almost always flush, preferably flush, but is not limited to this.
Specifically, a plurality of protrusions 35 are integrally provided on the other side surface (the surface on the panel material 50 side) 34 of the second member 30 at intervals in the vertical direction. It contacts, preferably presses, the surface 50a of the panel material 50.
That is, the protruding piece 35 is substantially flush with the other end of the surface member 10 in the width direction, preferably flush with the other end.
[0022]
The first member 20 is wide and hardly displaced in the width direction of the surface member 10. A notch 13 is formed on the back surface 11 of the front surface member 10 so as to be continuous with the other side surface 27 of the first member 20 in the width direction. (A side portion) is easily bent and deformed.
The width of the second member 30 is smaller than that of the first member 20, and the second member 30 is easily deformed in the width direction of the surface member 10.
A portion of the one side surface 32 of the second member 30 in the width direction (a surface facing the first member 20), which is continuous with the back surface 11 of the front member 10, is cut out. In the width direction.
[0023]
Thus, when the locking portion 31 of the second member 30 is locked to the support portion 22 (the upper surface of the protruding piece 28) of the first member 20 as shown in FIG. , The second member 30 itself is curved and displaced in the width direction, and the protruding piece 35 and the other end in the width direction of the surface member 10 maintain substantially the same form.
[0024]
Next, a method of fixing the panel member 50 will be described with reference to FIG.
The gasket 46 is attached to the groove 45 on the other side 44 of the panel member fitting groove 41 of the frame member 40. The gasket 46 is a conventional gasket, but the gasket 1 of the present invention may be used.
The end surface of the panel material 50 is in contact with a block 51 provided at the bottom of the panel material fitting groove 41, and the other side surface 50 a of the panel material 50 is in contact with the gasket 46.
The gasket 1 is formed to have a narrow width as shown in FIG. 2, and a portion of the surface member 10 closer to the first member 20 (a portion closer to one side in the width direction) is pressed to thereby make the surface 50 a of the panel member 50 and one side of the panel member fitting groove 41. 43, the gasket 1 is pushed.
[0025]
When the thickness of the panel material 50 is large, the gasket 1 is pushed into a predetermined position (a position where the first member 20 is completely mounted on the side portion 43 of the panel material fitting groove 41). The surface member 10 is in contact with the opening edge portion 42 of the panel material fitting groove 41 and the surface 50a of the panel material 50 while the member 10 remains in the narrow width form, so that airtightness and watertightness therebetween are ensured.
When the thickness of the panel member 50 is small, the surface member 10 does not contact the surface 50a of the panel member 50 even if the gasket 1 is pushed to the above-described predetermined position. Press the part on the other side).
As a result, the second member 30 moves with respect to the first member 20 and the surface member 10 assumes the wide form shown in FIG. 1, and the surface member 10 contacts (preferably presses) the surface 50 a of the panel member 50. .
[0026]
The panel member 50 is a double-layer glass as shown in FIG. 3, but is not limited to this, and may be a single-plate ballast, a metal panel, or a resin panel.
Further, in FIG. 3, the gasket 1 of the present invention is provided only on the indoor side, but it is needless to say that the gasket 1 may be provided only on the outdoor side.
[0027]
In the above-described embodiment, the width of the surface member 10 is changed after the gasket 1 is pushed. However, the width of the surface member 10 can be changed before the gasket 1 is pushed.
[0028]
【The invention's effect】
According to the first aspect of the present invention, the width dimension of the gasket can be adjusted by forming the surface member into a wide form or a narrow form.
The gasket includes a surface member, a first member, and a second member, and since they are integral, the gasket is integrally formed between the opening edge of the panel material fitting groove, the side portion, and the surface of the panel material. The work of fixing the panel material to the panel material fitting groove of the frame material is easy.
Moreover, the manufacture, transportation, and storage of the gasket are easy.
Since the surface of the surface member is the surface of the gasket, and the surface of the surface member is continuous in the width direction, rainwater or the like does not enter the inside of the gasket from the surface of the gasket, and the life of the gasket is long.
[0029]
According to the second aspect of the present invention, the first member is attached to the side of the panel material fitting groove by pushing the surface member toward one side in the width direction in a narrow form in which the locking portion is locked to the support portion. When the panel member is supported and the thickness of the panel member is thin, the surface member can be brought into a wide form so as to come into contact with the surface of the panel member by pushing the surface member toward the other side in the width direction to remove the locking portion from the support portion.
[0030]
According to the invention according to claim 3, the second member is in contact with the surface of the panel member together with the surface member, so that the airtightness and the watertightness are improved.
