以下、本発明の実施の形態を図面に基づいて説明する。図１〜４は、本発明の建具の第１実施形態（請求項１記載の発明の実施形態）を示している。本建具は、ビルの躯体開口部に取付けられて窓（連窓）を構成するものであり、図１，２に示すように、建具枠１と、建具枠１の上部を建具枠上側の躯体８ａに連結する上部ブラケット（ブラケット）２と、建具枠１の下部を建具枠下側の躯体８ｂに連結する下部ブラケット９とを備えている。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 4 show a first embodiment of the fitting of the present invention (the embodiment of the invention according to claim 1). This joinery is attached to the opening of the building frame to form a window (continuous window), and as shown in FIGS. 1 and 2, the joinery frame 1 and the upper part of the joinery frame 1 are the frame above the joinery frame. An upper bracket (bracket) 2 connected to 8a and a lower bracket 9 connecting the lower part of the fitting frame 1 to the skeleton 8b on the lower side of the fitting frame are provided.

建具枠１は、上枠１０と下枠１１と左右の縦枠１２，１２を枠組みし、その内側にガラス１３を嵌め込んで構成してある。図１に示すように、上枠１０と躯体８ａとの間の隙間には、ヒレ状のタイト材１４と伸縮自在なパッキン１５が設けてある。下枠１１と躯体と８ｂの間は、シール材１６でシールしてある。建具枠１は、図２に示すように、左右方向に複数並べて設けてあり、隣接する縦枠１２，１２間の隙間をシール材１７でシールしてある。上枠１０と下枠１１と縦枠１２は、図１に示すように、エッジクリアランス１８を小さくし、見付寸法をなるべく細くしてある。 The joinery frame 1 is configured by framing an upper frame 10, a lower frame 11, and left and right vertical frames 12, 12 and fitting glass 13 inside the frame. As shown in FIG. 1, a fin-shaped tight material 14 and a stretchable packing 15 are provided in the gap between the upper frame 10 and the skeleton 8a. The space between the lower frame 11 and the skeleton and 8b is sealed with a sealing material 16. As shown in FIG. 2, a plurality of fitting frames 1 are provided side by side in the left-right direction, and a gap between adjacent vertical frames 12 and 12 is sealed with a sealing material 17. As shown in FIG. 1, the upper frame 10, the lower frame 11, and the vertical frame 12 have the edge clearance 18 reduced and the found dimensions as thin as possible.

建具枠１は、上下寸法に対して左右寸法が大きい横長の長方形になっており、そのため地震の揺れ（特に横揺れ）に伴う躯体８ａ，８ｂの変形の影響を受けやすい。そこで本建具は、地震による大きな荷重を受けて躯体８ａ，８ｂが変形（変位）しても、建具枠１が変形せずガラス１３が破損しないように、建具枠１の上部を躯体８ａに連結する上部ブラケット２に、躯体８ａの変位を吸収する機構を備えている。 The joinery frame 1 has a horizontally long rectangle whose left and right dimensions are larger than the vertical dimensions, and is therefore susceptible to deformation of the skeletons 8a and 8b due to the shaking of an earthquake (particularly the rolling). Therefore, in this fitting, the upper part of the fitting frame 1 is connected to the skeleton 8a so that the fitting frame 1 is not deformed and the glass 13 is not damaged even if the skeletons 8a and 8b are deformed (displaced) by a large load due to an earthquake. The upper bracket 2 is provided with a mechanism for absorbing the displacement of the skeleton 8a.

上部ブラケット２は、図２に示すように、左右に隣り合う建具枠１，１の上部に跨って設けてあり、建具枠１，１に取付く建具枠取付部３と、躯体８ａに取付く躯体取付部４と、建具枠取付部３と躯体取付部４とをつなぐスライド部５とを有している。
建具枠取付部３は、図３に示すように、右側の建具枠１に取付く右側建具枠取付部材１９と、左側の建具枠１に取付く左側建具枠取付部材２０とに分割してあり、各建具枠取付部材１９，２０の左右両端部にベアリング取付部２１が設けてあり、各ベアリング取付部２１には、後述するスライド部５の横ガイド部材２２を周囲の三方から挟み込むように、ベアリング２３が３つずつ回転自在に取付けられており、これらのベアリング２３が回転することで横ガイド部材２２（スライド部５）が建具枠取付部３に対して抵抗なくスムーズに左右方向にスライドする。
躯体取付部４は、図２，３に示すように、躯体８ａにボルト・ナット２４で取付けられるプレート２５と、プレート２５の左右両端部に垂下して設けた丸棒状の縦ガイド部材２６，２６とを有している。縦ガイド部材２６の下端には、スライド部材５が下に抜け落ちるのを防ぐストッパー２７が設けてある。
スライド部５は、図１〜３に示すように、左右方向に水平にのびる丸棒状の横ガイド部材２２と、横ガイド部材２２から上方に立ち上げた左右の立ち上げ片２８，２８と、左右の立ち上げ片２８，２８にそれぞれ取付けられたベアリング取付部２９を有し、各ベアリング取付部２９には、躯体取付部４の縦ガイド部材２６を周囲の三方から挟み込むように、ベアリング３０が上部と下部に３つずつ回転自在に取付けられており、これらのベアリング３０が回転することで、スライド部５が躯体取付部３の縦ガイド部材２６に対して抵抗なくスムーズに上下方向にスライドする。 As shown in FIG. 2, the upper bracket 2 is provided so as to straddle the upper parts of the fitting frames 1 and 1 adjacent to each other on the left and right, and is attached to the fitting frame mounting portion 3 to be attached to the fitting frames 1 and 1 and the skeleton 8a. It has a skeleton mounting portion 4, and a slide portion 5 that connects the fitting frame mounting portion 3 and the skeleton mounting portion 4.
As shown in FIG. 3, the joinery frame mounting portion 3 is divided into a right joiner frame mounting member 19 attached to the right joiner frame 1 and a left joiner frame mounting member 20 attached to the left joiner frame 1. Bearing mounting portions 21 are provided at both left and right ends of the fitting frame mounting members 19 and 20, and the lateral guide members 22 of the slide portion 5, which will be described later, are sandwiched between the bearing mounting portions 21 from three surrounding sides. Three bearings 23 are rotatably attached, and when these bearings 23 rotate, the lateral guide member 22 (sliding portion 5) slides smoothly in the left-right direction without resistance to the fitting frame attachment portion 3. ..
As shown in FIGS. 2 and 3, the skeleton mounting portion 4 includes a plate 25 to be mounted on the skeleton 8a with bolts and nuts 24, and round bar-shaped vertical guide members 26, 26 provided hanging on both left and right ends of the plate 25. And have. At the lower end of the vertical guide member 26, a stopper 27 is provided to prevent the slide member 5 from falling out.
As shown in FIGS. 1 to 3, the slide portion 5 includes a round bar-shaped horizontal guide member 22 extending horizontally in the left-right direction, left and right bearing pieces 28 and 28 raised upward from the horizontal guide member 22, and left and right. Each of the bearing mounting portions 29 has a bearing mounting portion 29 attached to each of the rising pieces 28 and 28, and the bearing 30 is upper portion of each bearing mounting portion 29 so as to sandwich the vertical guide member 26 of the skeleton mounting portion 4 from three surrounding sides. And three bearings are rotatably attached to the lower part, and by rotating these bearings 30, the slide portion 5 slides smoothly in the vertical direction without resistance to the vertical guide member 26 of the skeleton attachment portion 3.

上部ブラケット２は以上のように構成され、スライド部５は、建具枠取付部３に対して建具枠１の縁に沿う面内方向（左右方向）にスライド自在である。さらにスライド部５は、躯体取付部４に対して建具枠１の縁に直交する面内方向（上下方向）にスライド自在である。これにより上部ブラケット２は、地震の際に上側の躯体８ａが下側の躯体８ｂに対して左右方向及び上下方向に変位しても、その変位を吸収することができる。吸収できる変位量は、右方向及び左方向にそれぞれ約３０ｍｍ、上方及び下方にそれぞれ約１５ｍｍとなっている。 The upper bracket 2 is configured as described above, and the sliding portion 5 is slidable with respect to the fitting frame mounting portion 3 in the in-plane direction (left-right direction) along the edge of the fitting frame 1. Further, the slide portion 5 is slidable in the in-plane direction (vertical direction) orthogonal to the edge of the fitting frame 1 with respect to the skeleton mounting portion 4. As a result, the upper bracket 2 can absorb the displacement even if the upper skeleton 8a is displaced with respect to the lower skeleton 8b in the horizontal direction and the vertical direction during an earthquake. The amount of displacement that can be absorbed is about 30 mm in the right and left directions, and about 15 mm in the upper and lower directions, respectively.

下部ブラケット９は、図１，２に示すように、建具枠１の下部を下側の躯体８ｂに動かないように固定している。 As shown in FIGS. 1 and 2, the lower bracket 9 fixes the lower portion of the fitting frame 1 to the lower skeleton 8b so as not to move.

図４は、地震が発生し、建具枠上側の躯体８ａが下側の躯体８ｂに対して右方向及び上方に変位したときの状態を示している。同図に示すように本建具は、躯体８ａがそのように変位したときに、スライド部５が建具枠１の縁に沿う面内方向にスライドし、且つ建具枠１の縁に直交する面内方向にスライドすることで躯体８ａの変位を吸収できるので、建具枠１の変形を防ぎ、ガラス１３の破損を防止することができる。スライド部５が、縦横のガイド部材２２，２６と、その周囲に配置したベアリング２３，３０によりスライドする構造としたので、抵抗なくスムーズにスライドさせられ、躯体８ａの変位に瞬時に追随できる。 FIG. 4 shows a state when an earthquake occurs and the skeleton 8a on the upper side of the fitting frame is displaced to the right and upward with respect to the skeleton 8b on the lower side. As shown in the figure, in this fitting, when the skeleton 8a is displaced in this way, the sliding portion 5 slides in the in-plane direction along the edge of the fitting frame 1 and in the plane orthogonal to the edge of the fitting frame 1. Since the displacement of the skeleton 8a can be absorbed by sliding in the direction, it is possible to prevent the fitting frame 1 from being deformed and the glass 13 from being damaged. Since the slide portion 5 has a structure that slides by the vertical and horizontal guide members 22 and 26 and the bearings 23 and 30 arranged around the slide portion 5, the slide portion 5 can be slid smoothly without resistance and can instantly follow the displacement of the skeleton 8a.

図５〜９は、本発明の建具の第２実施形態（請求項２記載の発明の実施形態）を示している。本建具３１は、図５，８，９に示すように、建物の１階部分の外壁を成すカーテンウォールに適用したものであり、左右方向に間隔をおいて設けた複数の方立６，６，…と、方立６，６，…の上部間に架設した上枠３２と、方立６，６，…の下部間に架設した下枠３３と、方立６，６，…と上枠３２と下枠３３とで形成される開口部に取付けたガラス３４と、方立６の上部を躯体３５に取付けるためのブラケット３６を備えている。建物は、図９に示すように、２階部分の躯体３５が屋外側に張り出しており、そのため２階での人の移動や屋根５１への積雪等により、２階の床を支える梁３５ａが上下に変位する（図５（ａ），（ｂ）参照）。そこで本建具は、ブラケット３６に梁３５ａの上下方向の変位を吸収する機構を設けてある。 FIGS. 5 to 9 show a second embodiment of the fitting of the present invention (the embodiment of the invention according to claim 2).

ブラケット２は、スライド部５が建具枠取付部３に対して建具枠１の縁に沿う面内方向にスライド自在であることに加え、スライド部５が躯体取付部４に対して建具枠１の縁に直交する面内方向にスライド自在であることで、地震の横揺れに伴う躯体８ａの横方向の変位に加え、地震の縦揺れに伴う躯体８ａの縦方向の変位も同時に吸収できる。
スライド部５は、ガイド部材２２，２６と、ガイド部材２２，２６に当接するベアリング２３，３０によりスライド自在としてあるので、抵抗なくスムーズにスライドし、躯体８ａの変位に瞬時に追随できる。 As described above, the present fitting (first embodiment) includes a fitting frame 1 and a bracket (upper bracket) 2 for attaching the fitting frame 1 to the skeleton 8a, and the bracket 2 is a fitting for attaching to the fitting frame 1. It has a frame mounting portion 3, a skeleton mounting portion 4 to be mounted on the skeleton 8a, and a slide portion 5 connecting the fitting frame mounting portion 3 and the skeleton mounting portion 4, and the slide portion 5 has a sliding portion 5 with respect to the fitting frame mounting portion 3. Since it can slide in-plane along the edge of the joinery frame 1, even if a large load is applied to the building and the skeleton 8a is deformed, the slide portion 5 slides in-plane along the edge of the joinery frame 1. By doing so, the deformation of the fitting frame 1 can be suppressed and the glass 13 can be prevented from being damaged. Further, since it is not necessary to take a large edge clearance 18, the design is also good.
In the bracket 2, the slide portion 5 is slidable with respect to the joinery frame mounting portion 3 in the in-plane direction along the edge of the joinery frame 1, and the slide portion 5 is of the joinery frame 1 with respect to the skeleton mounting portion 4. By being slidable in the in-plane direction orthogonal to the edge, in addition to the lateral displacement of the skeleton 8a due to the rolling motion of the earthquake, the vertical displacement of the skeleton 8a accompanying the pitching of the earthquake can be absorbed at the same time.
Since the slide portion 5 is slidable by the guide members 22 and 26 and the bearings 23 and 30 in contact with the guide members 22 and 26, the slide portion 5 can slide smoothly without resistance and can instantly follow the displacement of the skeleton 8a.

本建具（第２実施形態）は、方立６又は縦枠よりなる縦材６と、縦材６を躯体３５に取付けるブラケット３６とを備え、ブラケット３６は、縦材６に取付く縦材取付部７と、躯体３５に取付く躯体取付部４と、縦材取付部７と躯体取付部４とをつなぐスライド部５とを有し、スライド部５は、躯体取付部４に対して上下方向にスライド自在であることで、建物に大きな荷重が加わって躯体３５が変形しても、スライド部５が上下方向にスライドすることで縦材６の変形を抑え、ガラス３４の破損を防ぐことができる。また、エッジクリアランス４３を大きく取る必要がないため、意匠性も良い。
スライド部５は、ガイド部材４９と、ガイド部材４９に当接するベアリング４８によりスライド自在としてあるので、抵抗なくスムーズにスライドし、躯体３５の変位に瞬時に追随できる。 The present fitting (second embodiment) includes a vertical member 6 composed of a mullion 6 or a vertical frame, and a bracket 36 for attaching the vertical member 6 to the skeleton 35, and the bracket 36 is attached to the vertical member 6 to be attached to the vertical member. It has a portion 7, a skeleton mounting portion 4 that is attached to the skeleton 35, and a slide portion 5 that connects the vertical member mounting portion 7 and the skeleton mounting portion 4, and the slide portion 5 is in the vertical direction with respect to the skeleton mounting portion 4. Even if the skeleton 35 is deformed due to a large load applied to the building, the sliding portion 5 slides in the vertical direction to suppress the deformation of the vertical member 6 and prevent the glass 34 from being damaged. it can. Further, since it is not necessary to take a large edge clearance 43, the design is good.
Since the slide portion 5 is slidable by the guide member 49 and the bearing 48 in contact with the guide member 49, the slide portion 5 can slide smoothly without resistance and can instantly follow the displacement of the skeleton 35.
