Description

【０００１】
【発明の属する技術分野】
本発明は、鏡板の取付構造に関し、詳しくは住宅等の建築物の開口部に取り付けられるドアや窓等を製造する際の鏡板の取付構造に関するものである。
【０００２】
【従来の技術】
従来から、住宅等の建築物の開口部に付設されるドアや窓には、矩形状に枠組みされた框材の内側に鏡板を取り付けた建具が広く使用されている。この框材１の内面に鏡板２を取り付けるにあたっては、図６に示すように、鏡板２の端部２ａを表裏両側から挟持する表裏一対の額縁材３を框材１に取り付けることによって行われている。従来では、先ず、一方の額縁材３を框材１内面の一端１ａ側にタッカー釘８ａで固定し、次いで、この一方の額縁材３に対して鏡板２の端部をタッカー釘８ｂで固定し、さらにその後、他方の額縁材３をタッカー釘８ｃで框材１内面の他端１ｂ側に固定するようにしている。
【０００３】
【発明が解決しようとする課題】
このため従来では、図７に示すように、タッカー釘８の数が増えて鏡板２の取り付け作業に非常に手間がかかり、生産能率が低下するという問題があり、しかも、図６に示すように、タッカー釘８ａ〜８ｃの頭部が額縁材３の外表面３ｅに露出するために外観が損なわれるばかりか、額縁材３にひび割れが発生するなどの問題もあった。
【０００４】
本発明は上記の点に鑑みてなされたものであり、その目的とするところは、タッカー釘を用いずに、鏡板の取り付け強度を十分に確保でき、しかも取り付け作業に手間がかから
ず、そのうえ優れた外観が得られる鏡板の取付構造を提供するにある。
【０００５】
【課題を解決するための手段】
上記課題を解決するために本発明は、矩形状に枠組みされた框材１の内面１ａの厚み方向Ａの中央側に鏡板２の端部２ａが接着され、框材１の内面１ａの厚み方向Ａの両側に鏡板２の端部２ａを両側から挟持するように表裏一対の額縁材３が接着された鏡板の取付構造であって、框材１と額縁材３間に隙間が設けられていると共に、額縁材３の該隙間と対向する外面３ａ側から額縁材３の内方Ｂに向かって凹溝状の接着剤溜まり部５が形成されており、上記隙間から接着剤溜まり部５内に接着剤６が充填される際、一方の額縁材３の接着剤溜まり部５には他方の額縁材３を接着する前に鏡板２を一方の額縁材３に仮支持するため硬化性に優れたホットメルト系接着剤６ａが充填され、他方の額縁材３の接着剤溜まり部５には発泡系接着剤６ｂが充填されて成ることを特徴としており、このように構成することで、接着剤溜まり部５内で接着剤６が硬化することによって、接着剤６によるアンカー効果が得られ、強固に額縁材３と框材１とを固着でき、従来のようなタッカー釘を用いずに、鏡板２の取り付け強度を十分に確保でき、しかも接着剤６を接着剤溜まり部５に注入するだけでよいので、鏡板２の取り付け作業がはかどり、そのうえ従来のようにタッカー釘の頭部が額縁材３表面に露出したり、ひび割れが発生するのを防止できる。また例えば先に框材１に取り付けられる一方の額縁材３の接着剤溜まり部５に硬化性に優れたホットメルト系接着剤６ａを充填することで、一方の額縁材３を框材１に対して速く接着できて、鏡板２を一方の額縁材３に対して仮支持できるようになる。さらに他方の額縁材３の接着剤溜まり部５に発泡系接着剤６ｂを充填することで、発泡系接着剤６が接着剤溜まり部５に隙間なく充填されて接着性が十分に確保されるようになる。
【０００６】
また上記凹溝状の接着剤溜まり部５は、入側５ａで狭く奥側５ｂで広くなった異径溝で構成されているのが好ましく、このように構成することで、硬化後の接着剤６が断面略Ｔ字状となって接着剤６によるアンカー効果が更に高まり、框材１に対する額縁材３及び鏡板２の接着強度を一層向上させることができる。
【０００７】
【発明の実施の形態】
以下、本発明の実施の形態を説明すると、図２に示すように、矩形状に枠組みされた框材１の内側に表裏一対の額縁材３を介して鏡板２の端部２ａが取り付けられて、ドア７が構成されている。框材１は、左右一対の縦枠１０，１０と、縦枠１０，１０の上下両端部間に横設される上枠１１と下枠１２とが枠組み一体化されている。框材１の内側の空間部には矩形状の鏡板２が配置される。鏡板２の四方の端部２ａは、図１に示すように、表裏一対の額縁材３によって両側から挟持された状態で、框材１の内面１ａの厚み方向Ａの中央側との間に隙間４ａをあけて配置され、隙間４ａに接着剤６が充填されている。鏡板２の材質は特に限定されず、ガラス製、木製、金属製等、いずれでもよい。また鏡板２は大きな一枚板に限らず、複数分割された板材を組み合わせたものであってもよい。
【０００８】
表裏一対の額縁材３は、鏡板２の四方の端部２ａに沿って配置されている。各額縁材３は、図１に示すように、框材１の内面１ａの厚み方向Ａの両側に配置されていると共に、框材１と各額縁材３との間には接着剤６が充填される隙間４ｂが設けられている。表裏一対の額縁材３は同じ構造をしており、各額縁材３は、図３に示すように、框材１の端縁に係止される係止部１３と、鏡板２の端部２ａを支持する鏡板支持部１４とが一体に形成されている。
【０００９】
額縁材３の裏面コーナー部３ｃ、つまり、框材１に対向する外面３ａと鏡板２に対向する内側面３ｂとのなす裏面コーナー部３ｃには、接着剤６が溜められる凹溝状の接着剤溜まり部５が設けられている。この接着剤溜まり部５は、額縁材３の略全長に亘って形成されており、裏面コーナー部３ｃから額縁材３の内方Ｂに向かって凹んでいる。本例では、接着剤溜まり部５は入側５ａでは狭く且つ奥側５ｂでは広くなる断面略Ｔ字状をした異径溝で構成されており、この異径溝の入側５ａが、框材１と額縁材３間の隙間４ｂ、及び框材１と鏡板２の端部２ａとの間の隙間４ａにそれぞれ連通している。
【００１０】
上記框材１と額縁材３間の隙間４ｂ、框材１と鏡板２の端部２ａとの間の隙間４ａ、及び各額縁材３の接着剤溜まり部５内には、それぞれ接着剤６が充填されている。接着剤６としては、ホットメルト系接着剤６ａ、発泡系接着剤６ｂが用いられる。
【００１１】
次に鏡板２の取り付け方法の一例を説明すると、図４に示すように、先ず、一方の額縁材３を框材１の内面１ａの厚み方向Ａの一端側に配置し、この額縁材３の内側面３ｂに鏡板２の端部２ａを当てた状態で、ホットメルト系接着剤６ａを框材１と鏡板２の端部２ａ間の隙間４ａから一方の額縁材３の裏面コーナー部３ｃに凹設されている接着剤溜まり部５内、及び額縁材３と框材１との隙間４ｂ内にそれぞれ注入する。またこのとき隙間４ａよりも表側（一方の額縁材３とは反対側）に突出するように発泡系接着剤６ｂを肉盛りしておく（図４のイ部）。この状態で、図４の矢印ロで示す方向から他方の額縁材３を押しつけると、上記肉盛りされている発泡系接着剤６ｂ（図４のイ部）がこの他方の額縁材３の接着剤溜まり部５に入り込む。またこのとき発泡系接着剤６ｂは框材１と他方の額縁材３との隙間４ｂにも入り込んで図１に示すように、他方の額縁材３と框材１とが接着される。これにより、表裏一対の額縁材３及び鏡板２が框材１にそれぞれ接着されると同時に、両額縁材３の接着剤溜まり部５内にそれぞれ接着剤６ａ，６ｂが充填されるようになり、接着剤溜まり部５内で接着剤６ａ，６ｂが硬化した後に、接着剤６ａ，６ｂによるアンカー効果が得られる。つまり、接着剤溜まり部５が、入側５ａでは狭く奥側５ｂでは広い断面略Ｔ字状をした異径溝で構成されているので、硬化後の接着剤６ａ，６ｂが断面略Ｔ字状となって框材１に対する額縁材３及び鏡板２の接着強度が増し、これにより、従来のようなタッカー釘を用いずに、鏡板２の取り付け強度を十分に確保できるものとなる。また、硬化性に優れたホットメルト系接着剤６ａを一方の額縁材３の接着剤溜まり部５に充填することで、一方の額縁材３を框材１に対して速く接着でき、他方の額縁材３を接着する前に、鏡板２を一方の額縁材３に仮支持できるものであり、さらに他方の額縁材３の接着剤溜まり部５に発泡系接着剤６ｂを充填することで、発泡系接着剤６ｂが凹溝状の接着剤溜まり部３に隙間なく充填されて、接着性が十分に確保されるという利点がある。
【００１２】
また、接着剤６ａ，６ｂを接着剤溜まり部５に注入するだけでよいので、鏡板２の取り付け作業がはかどり、生産効率が向上する。そのうえ、従来のようにタッカー釘の頭部が額縁材３表面に露出して外観が損なわれたり、額縁材３にひび割れが発生するなどの問題も同時に解消できると共に、タッカー釘を用いないので、鏡板２としてガラス板や木板、金属板等、任意の種類を選ぶことが可能となり、さらに框材１と額縁材３と鏡板２間の隙間４ａ，４ｂには接着剤６がそれぞれ充填されるので、隙間４ａ，４ｂによるガタツキが発生することもないものである。
【００１３】
接着剤溜まり部５の例として、前記例では断面略Ｔ字状の異径溝を例示したが、異径溝ではなく、例えば図５（ａ）（ｂ）に示すように、入側５ａと奥側５ｂの広さが同じコ字状溝５′、５″であってもよく、或いは図５（ｃ）に示すように、奥側５ｂが分岐した二股状溝であってもよいものであり、要するに額縁材３の内方Ｂに接着剤６を溜めることができる空間部を有していればよいものである。
【００１４】
尚、接着剤溜まり部５は額縁材３の略全長に亘って形成される以外に、一定間隔をあけてスポット的に形成してもよいものである。
【００１５】
【発明の効果】
上記のように本発明のうち請求項１記載の発明は、矩形状に枠組みされた框材の内面の厚み方向の中央側に鏡板の端部が接着され、框材の内面の厚み方向の両側に鏡板の端部を両側から挟持するように表裏一対の額縁材が接着された鏡板の取付構造であって、框材と額縁材間に隙間が設けられていると共に、額縁材の該隙間と対向する外面側から額縁材の内方に向かって凹溝状の接着剤溜まり部が形成されており、上記隙間から接着剤溜まり部内に接着剤が充填されて成るので、接着剤溜まり部内での接着剤の硬化によるアンカー効果が得られ、強固に額縁材と框材とを固着でき、従来のようなタッカー釘を用いずに、鏡板の取り付け強度を十分に確保できるものとなる。しかも、接着剤を接着剤溜まり部に注入するだけでよいので、鏡板の取り付け作業がはかどり、生産効率が向上すると共に、従来のようにタッカー釘の頭部が額縁材表面に露出して外観が損なわれたり、額縁材にひび割れが発生するなどの問題も同時に解消できる。さらに框材と額縁材と鏡板間の隙間には接着剤がそれぞれ充填されるので、隙間によるガタツキが発生することもなくなる。また一方の額縁材の接着剤溜まり部には他方の額縁材を接着する前に鏡板を一方の額縁材に仮支持するため硬化性に優れたホットメルト系接着剤が充填され、他方の額縁材の接着剤溜まり部には発泡系接着剤が充填されているので、例えば、先に框材に取り付けられる一方の額縁材の接着剤溜まり部に硬化性に優れたホットメルト系接着剤を充填することで、一方の額縁材を框材に対して速く接着でき、鏡板を一方の額縁材に対して仮支持できて、鏡板の取り付け作業が一層はかどることができるものであり、しかも他方の額縁材の接着剤溜まり部に発泡系接着剤を充填することで、発泡系接着剤が接着剤溜まり部に隙間なく充填されて接着性が十分に確保されるようになるものである。
【００１６】
また請求項２記載の発明は、請求項１記載の効果に加えて、凹溝状の接着剤溜まり部は、入側で狭く奥側で広くなった異径溝で構成されているので、硬化後の接着剤が断面略Ｔ字状となって接着剤によるアンカー効果が更に高まり、框材に対する額縁材及び鏡板の接着強度が一層増し、取り付け強度が更に向上する。

[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described. As shown in FIG. 2, an end 2 a of a mirror plate 2 is attached to the inside of a rectangular frame member 1 via a pair of front and back frame members 3. , A door 7. The frame member 1 has a pair of left and right vertical frames 10, 10, and an upper frame 11 and a lower frame 12 provided horizontally between upper and lower ends of the vertical frames 10, 10. A rectangular end plate 2 is arranged in a space inside the frame material 1. As shown in FIG. 1, the four ends 2 a of the end plate 2 are sandwiched by a pair of frame members 3 on both sides, and a gap is formed between the end 2 a and the center of the inner surface 1 a of the frame member 1 in the thickness direction A. The gap 4a is filled with the adhesive 6 with the gap 4a. The material of the end plate 2 is not particularly limited, and may be glass, wooden, metal, or the like. The end plate 2 is not limited to a single large plate, and may be a combination of a plurality of divided plate members.
[0008]
The pair of frame members 3 on the front and back sides are arranged along the four ends 2 a of the end plate 2. As shown in FIG. 1, each frame material 3 is disposed on both sides in the thickness direction A of the inner surface 1 a of the frame material 1, and an adhesive 6 is filled between the frame material 1 and each frame material 3. A gap 4b is provided. The pair of front and back frame members 3 have the same structure, and each frame member 3 has, as shown in FIG. 3, a locking portion 13 that is locked to an edge of the frame member 1 and an end 2 a of the end plate 2. Are integrally formed with the end plate supporting portion 14 for supporting the lens.
[0009]
A concave groove-shaped adhesive in which the adhesive 6 is stored is formed on the back surface corner 3c of the frame material 3, that is, on the back surface corner 3c formed by the outer surface 3a facing the frame material 1 and the inner surface 3b facing the end plate 2. A reservoir 5 is provided. The adhesive pool portion 5 is formed over substantially the entire length of the frame material 3 and is recessed from the back corner 3c toward the inside B of the frame material 3. In the present example, the adhesive reservoir 5 is formed of a groove having a substantially T-shaped cross section that is narrow on the entry side 5a and wide on the back side 5b, and the entry side 5a of the groove has a frame material. 1 and a frame member 3 and a gap 4a between the frame member 1 and the end 2a of the end panel 2 respectively.
[0010]
In the gap 4b between the frame material 1 and the frame material 3, the gap 4a between the frame material 1 and the end 2a of the end plate 2, and the adhesive pool 5 of each frame material 3, an adhesive 6 is provided. Is filled. As the adhesive 6, a hot melt adhesive 6a and a foam adhesive 6b are used .
[0011]
Next, an example of a method of attaching the end plate 2 will be described. As shown in FIG. 4, first, one frame material 3 is arranged on one end side in the thickness direction A of the inner surface 1 a of the frame material 1. While the end 2a of the end plate 2 is in contact with the inner surface 3b, the hot-melt adhesive 6a is recessed from the gap 4a between the frame member 1 and the end 2a of the end plate 2 to the back corner 3c of one of the frame members 3. It is injected into the provided adhesive pool 5 and into the gap 4b between the frame material 3 and the frame material 1, respectively. At this time , the foamed adhesive 6b is overlaid so as to protrude from the gap 4a to the front side (the side opposite to the one frame material 3) (a portion in FIG. 4). In this state, when the other frame material 3 is pressed in the direction shown by the arrow B in FIG. 4, the foamed adhesive 6b (a portion in FIG. 4) which has been overlaid is bonded to the adhesive of the other frame material 3. It enters the pool part 5. At this time, the foam adhesive 6b also enters the gap 4b between the frame material 1 and the other frame material 3, and the other frame material 3 and the frame material 1 are bonded as shown in FIG. As a result, the pair of frame members 3 and the end plate 2 are bonded to the frame member 1 respectively, and at the same time, the adhesives 6a and 6b are filled in the adhesive reservoirs 5 of the both frame members 3, respectively. After the adhesives 6a and 6b are hardened in the adhesive reservoir 5, an anchor effect by the adhesives 6a and 6b is obtained. That is, since the adhesive reservoir 5 is formed of a groove having a substantially T-shaped cross section that is narrow on the entry side 5a and wide on the back side 5b, the adhesives 6a and 6b after curing have a substantially T-shaped cross section. As a result, the bonding strength of the frame member 3 and the end plate 2 to the frame member 1 is increased, whereby the mounting strength of the end plate 2 can be sufficiently secured without using a conventional tucker nail. Also, by filling the adhesive pool 5 of the one frame material 3 with the hot-melt adhesive 6a having excellent curability, one frame material 3 can be quickly bonded to the frame material 1, and the other frame material can be bonded. Before bonding the material 3, the end plate 2 can be temporarily supported on one of the frame materials 3, and the adhesive pool 5 of the other frame material 3 is filled with a foaming adhesive 6 b to form a foaming system. There is an advantage that the adhesive 6b is filled in the concave groove-shaped adhesive reservoir 3 without gaps, and the adhesiveness is sufficiently ensured.
[0012]
Further, since it is only necessary to inject the adhesives 6a and 6b into the adhesive reservoir 5, the work of attaching the end plate 2 is accelerated, and the production efficiency is improved. In addition, the problem that the head of the tucker nail is exposed on the surface of the frame material 3 and the appearance is impaired as in the related art, and that the frame material 3 is cracked can be solved at the same time, and no tucker nail is used. Any kind of glass plate, wood plate, metal plate, etc. can be selected as the mirror plate 2, and the gaps 4 a and 4 b between the frame material 1, the frame material 3 and the mirror plate 2 are filled with the adhesive 6, respectively. Also, rattling due to the gaps 4a and 4b does not occur .
[0013]
As an example of the adhesive reservoir 5, in the above-described example, a different-diameter groove having a substantially T-shaped cross section has been illustrated, but not the different-diameter groove, for example, as shown in FIGS. The width of the back side 5b may be the same U-shaped groove 5 ′, 5 ″, or, as shown in FIG. 5 (c), the back side 5b may be a branched bifurcated groove. In short, what is necessary is just to have a space in which the adhesive 6 can be stored inside B of the frame material 3.
[0014]
The adhesive pool 5 may be formed over the entire length of the frame material 3 or may be formed in spots at regular intervals .
[0015]
