Description

本発明は、複数枚のガラス板を備えた多重ガラス障子用の端面保護カバー及び当該端面保護カバーを用いた多重ガラス障子に関する。 The present invention relates to an end face protective cover for a multiple glass shoji provided with a plurality of glass plates, and a multiple glass shoji using the end face protective cover.

２枚のガラス板を、スペーサーを介して隔置し、中空層が形成されてなる複層ガラスは、断熱性及び防音性に優れており、住宅、その他各種建造物の窓用として広く普及している。
このタイプの複層ガラスにおいて、間隔をあけて配設した２枚のガラス板の間に、上下框及び左右の縦框を内装して構成した複層ガラス障子が特許文献１として知られている。
又、複層ガラスを用いた複層ガラス障子構造として、２枚のガラス板を、当該板ガラス間の周縁部内側に凹陥部が形成されるようにガラス板の周縁部の内側に内部スペーサーを介して、該２枚のガラス板間に中空層が形成されるようにして複層ガラスを構成し、この複層ガラスの周縁部の前記凹陥部に保持枠を取付けてなる複層ガラス障子構造が、特許文献２として知られている。 Double-glazed glass in which two glass plates are separated by a spacer and formed with a hollow layer is excellent in heat insulation and soundproofing, and is widely used for windows in houses and other various buildings. ing.
In this type of multi-layer glass, Patent Document 1 discloses a multi-layer glass shoji in which upper and lower ridges and left and right vertical ridges are housed between two glass plates arranged at intervals.
In addition, as a double-glazed shoji structure using double-glazed glass, two glass plates are placed inside the peripheral edge of the glass plate with an internal spacer so that a concave portion is formed inside the peripheral edge between the glass plates. A double-layer glass shoji structure in which a double-layer glass is formed such that a hollow layer is formed between the two glass plates, and a holding frame is attached to the recessed portion at the peripheral edge of the double-layer glass. This is known as Patent Document 2.

特許文献１に記載の複層ガラス障子は、２枚のガラス板の間に上下框及び左右の縦框を内装することにより、２枚のガラス板の間に広い空間を形成することが容易で、断熱性及び遮音性を高めることができるとともに、表裏の面のガラス板の透視領域のガラス面積の拡大化を図ることにより、美観的にも優れた複層ガラス障子が得られるとされている。
又、特許文献２に記載の複層ガラス障子構造は、框の面積が小さくされており、採光性、意匠性が改善され、開放感があり、框の面積が小さいため、熱損失も少なくすることができ、框の結露の問題も改善できるとされている。 The multi-layer glass shoji described in Patent Document 1 is easy to form a wide space between two glass plates by installing upper and lower folds and left and right vertical folds between the two glass plates, It is said that a multi-layer glass shoji excellent in aesthetics can be obtained by improving the sound insulation and enlarging the glass area of the see-through region of the front and back glass plates.
In addition, the double-glazed shoji structure described in Patent Document 2 has a small ridge area, improved daylighting and design, a feeling of openness, and a small ridge area, thus reducing heat loss. It is said that the problem of dew condensation on cocoons can be improved.

しかしながら、住宅、その他各種建造物の窓のデザインの多様化から、更に採光性能、意匠性及び開放感が優れ、かつ熱損失の少ない複層ガラス障子構造が望まれておる。
又、既存の住宅、その他各種建造物等の窓の室内側にもう一つの内窓を配設し、二重窓化して、防音性、断熱性、防犯性を高める場合、内窓の障子は、より厚さが薄く、開口部が広くて開放感があり、意匠性に優れたものが要求される。
一方、従来の複層ガラスを用いて窓の障子を製作する場合、例えば、２枚のガラス板を、スペーサーを用いて隔置して中間に中空層を有する複層ガラスを製作し、この複層ガラスの周縁部に框を組付けて複層ガラス障子を製作するという複層ガラス製作工程及び框の組付け工程を経るため、部品点数が多く、又組立工数が多いという難点があった。 However, from the diversification of the design of houses and other various windows, there is a demand for a multi-layer glass shoji structure that is further superior in daylighting performance, designability and openness and has little heat loss.
In addition, when another inner window is installed on the indoor side of the window of an existing house, other various buildings, etc., and double windows are used to improve soundproofing, heat insulation, and crime prevention, the shoji of the inner window is Therefore, it is required to have a thinner thickness, a wide opening, a feeling of opening, and an excellent design.
On the other hand, when manufacturing a window screen using conventional multilayer glass, for example, a multilayer glass having a hollow layer in the middle by separating two glass plates using a spacer is manufactured. Since a double-glazed glass manufacturing process and a double-glazed assembling process for manufacturing a double-glazed glass shoji by assembling a heel on the peripheral edge of the laminated glass, there are problems in that the number of parts is large and the number of assembly steps is large.

本発明者は、上記したような要求及び難点の改善された複層ガラス障子、即ち多重ガラス障子として、先に、第１のガラス板と第２のガラス板とをその周囲において枠体により隔置し、中空層を形成してなる多重ガラス障子であって、前記枠体は、前記第１及び第２のガラス板の間隔を保持する内面部及び外面側部と、当該内面部及び外面側部に連設されガラス板の内側に面する側辺部と、乾燥剤を収納する空間部とを有するスペーサー部と、前記第１及び第２のガラス板の周縁部の内側に面する左右一対の縦框部を有する框部とを備え、当該枠体のスペーサー部と框部とは、枠体成型材料により一体成型されてなる多重ガラス障子に関する発明を特許出願した。 The present inventor firstly separated the first glass plate and the second glass plate by a frame around the first glass plate and the second glass plate as a multi-layer glass shoji having improved requirements and difficulties as described above. A multiple glass shoji that is formed by forming a hollow layer, wherein the frame includes an inner surface portion and an outer surface side portion that maintain a distance between the first and second glass plates, and the inner surface portion and the outer surface side. A pair of left and right sides facing the inside of the peripheral portions of the first and second glass plates, and a spacer portion having a side portion facing the inside of the glass plate that is connected to the portion and a space portion that stores the desiccant A patent application was filed for an invention relating to a multiple glass shoji which is formed by integrally molding a spacer portion and a collar portion of the frame body with a frame body molding material.

When y1 and the thickness of the vertical flange portion 11 of the frame 3 is z1, it is preferable to satisfy y1 + z1 ≧ x1, and in the right fitting portion 33, the fitting groove portion inside the upper end portion of the bent portion 34 The width x2 is preferably y2 + z2 ≧ x2, where y2 is the thickness of the first glass plate 2a and z2 is the thickness of the vertical flange 11 of the frame 3. Thus, by designing the widths x1 and x2 of the upper end of the fitting groove portion of the fitting portion 33, the end face protection cover can be easily and reliably attached to the frame 3. In addition, when multiple glass shojis are used for the sliding window, at least the outside of the bent part is made of a wear-resistant synthetic resin material to prevent wear due to contact with the end face protective cover of the multiple glass shoji when sliding. It can also be formed.

端部保護カバー３０が、多重ガラス障子の上辺側、左側辺側、又右側辺側の溝部１７に設けられる場合、上辺側、左側辺側、又右側辺側において要求される機能に応じて、端部保護カバー３０の構造を変更することができる。例えば、引き違い窓方式の多重ガラス障子に利用される場合、引き違いされる側の端部保護カバーの側部に図１０に示すように召し合せ部気密材４０を付設してもよい。
又、引き違い戸の場合、障子用の戸車が装着されるので、戸車を除く部分に上記した端部保護カバーを設ければよい。なお、引き違い窓方式の場合、下辺側への端面保護カバーの装着を行なわず、多重ガラス障子の上辺側、側辺側においては、上記した端部保護カバー３０を配設してもよい。 When the end protection cover 30 is provided in the groove portion 17 on the upper side, the left side, or the right side of the multiple glass shoji, depending on the function required on the upper side, the left side, or the right side, The structure of the end protection cover 30 can be changed. For example, when used in a sliding window type multiple glass shoji, a summing portion airtight member 40 may be attached to the side portion of the end protection cover on the side to be pulled back as shown in FIG.
Further, in the case of a sliding door, a door for shoji is installed, so the end protection cover described above may be provided in a portion excluding the door. In the case of the sliding window method, the end face protection cover 30 may be provided on the upper side and the side of the multiple glass shoji without attaching the end face protection cover to the lower side.

なお、多重ガラス障子の開閉方式がスイング方式の場合には、戸車が必要でないので、左側辺側、右側辺側及び上辺側の端部保護カバーは、戸車に対応する構造変更は不要であり、下辺側、上辺側、左側辺側、及び右側辺側を同様の構造とすることができる。
特に、第１及び第２のガラス板が矩形形状である多重ガラス障子の４辺のうち、少なくともに上辺側、両側辺側における枠体への端面保護カバーとして、上記した同様な形状のものを使用すれば、端面保護カバーの共通化を図ることができ、多重ガラス障子の組み付け部品点数の削減に効果的である。 In addition, when the opening and closing method of the multiple glass shoji is a swing method, since a door is not required, the left side, right side, and upper side end protection covers do not require structural changes corresponding to the door. The lower side, the upper side, the left side, and the right side can have the same structure.
In particular, among the four sides of the multiple glass shoji in which the first and second glass plates have a rectangular shape, at least the upper side and the side surface of the same shape as the end face protection cover to the frame on the both sides. If used, the end face protection cover can be shared, which is effective in reducing the number of parts for assembling the multiple glass shoji.

枠体３のスペーサー部１０の側辺部８、８と框部１３の縦框部１１、１１とが連設した枠体３の第１及び第２のガラス板２ａ、２ｂと面する部分の構造は、図８に示すように、枠体３のスペーサー部１０の側辺部８、８及び／又は框部１３の縦框部１１、１１の第１及び第２のガラス板２ａ、２ｂと対面する面に凹状部１８が形成されていてもよい。このような凹状部１８が形成されていれば、接着材層２１の厚さをこの凹状部１８の領域において、より厚くすることができ、接着性、封止性を高めることができる。 Of the part facing the first and second glass plates 2a, 2b of the frame 3 in which the side portions 8, 8 of the spacer 10 of the frame 3 and the vertical flanges 11, 11 of the flange 13 are connected. As shown in FIG. 8, the structure includes side portions 8 and 8 of the spacer portion 10 of the frame body 3 and / or first and second glass plates 2 a and 2 b of the vertical flange portions 11 and 11 of the flange portion 13, and A concave portion 18 may be formed on the facing surface. If such a concave portion 18 is formed, the thickness of the adhesive layer 21 can be made thicker in the region of the concave portion 18, and the adhesiveness and sealing performance can be improved.

You may make it the shape which bend | folds in the inner side direction of 17 and the tip extends in the front-end | tip direction of 1st and 2nd glass plate 2a, 2b. In the structure of the vertical flange portions 11, 11 having such a bent tip portion 23, the concave portion 24 is formed in the peripheral portion of the first and second glass plates 2 a, 2 b. If the sealing material 25 which is low and has excellent adhesiveness is encapsulated, the adhesiveness and sealing performance of the multiple glass shoji can be further improved. In addition, it is good also as not providing the bending front-end | tip part 23 in the front-end | tip part of the vertical collar parts 11 and 11 of the above-mentioned collar part 13, but making the front-end | tips of the vertical collar parts 11 and 11 into a linear form.
