Description
本発明は、トップライトに関する。 The present invention relates to a skylight.
従来より、方立と無目を格子状に組み、これにガラスを保持させて構成したトップライトが知られている。かかるトップライトにおいては、施工性を向上したいという要望があった。 Conventionally, skylights have been known that consist of a grid of mullions and baffles, with glass held in place by these. However, there has been a demand for improved ease of installation for such skylights.
本発明は以上に述べた実情に鑑み、施工性が良好なトップライトの提供を目的とする。 In light of the above-mentioned circumstances, the present invention aims to provide a skylight that is easy to install.
上記の課題を達成するために請求項１記載の発明によるトップライトは、上方立と、下方立と、右無目と、左無目とを備え、上方立と下方立は、ガラス間口と、ガラス間口の下方に位置する中空部を有し、中空部内に排水樋が上方立と下方立とに連続して設けてあり、右無目と左無目は、ガラス間口を有し、ガラス間口の長手方向端部が上方立と下方立の間に位置しており、右無目と左無目のガラス間口の底壁は、上方立のガラス間口の底壁よりも低い位置にあって、長手方向端部を排水樋にのぞませてあり、上方立のガラス間口に入った水が無目のガラス間口に入ってから排水樋に流れ、無目のガラス間口に入った水が排水樋に流れることを特徴とする。 To achieve the above objective, the skylight according to the invention of claim 1 comprises an upper stand, a lower stand, a right blind, and a left blind. The upper stand and the lower stand have glass openings and hollow sections located below the glass openings, with drainage gutters provided continuously between the upper stand and the lower stand within the hollow sections. The right and left blinds have glass openings, the longitudinal ends of which are located between the upper stand and the lower stand. The bottom walls of the glass openings of the right and left blinds are located lower than the bottom wall of the glass opening of the upper stand, with their longitudinal ends facing the drainage gutters. Water that enters the glass opening of the upper stand enters the glass opening of the blinds and then flows into the drainage gutters, and water that enters the glass opening of the blinds flows into the drainage gutters.
請求項１記載の発明によるトップライトは、上方立と、下方立と、右無目と、左無目とを備え、上方立と下方立は、ガラス間口と、ガラス間口の下方に位置する中空部を有し、中空部内に排水樋が上方立と下方立とに連続して設けてあり、右無目と左無目は、ガラス間口を有し、ガラス間口の長手方向端部が上方立と下方立の間に位置しており、右無目と左無目のガラス間口の底壁は、上方立のガラス間口の底壁よりも低い位置にあって、長手方向端部を排水樋にのぞませてあり、上方立のガラス間口に入った水が無目のガラス間口に入ってから排水樋に流れ、無目のガラス間口に入った水が排水樋に流れるので、方立及び無目の長手方向端部同士の隙間をシールする必要がなく、施工性が良い。しかも、方立のガラス間口に入った水、無目のガラス間口に入った水が、漏れなく方立の中空部内に設けた排水樋を通じて排水されるため、止水性にも優れている。 The skylight according to the invention of claim 1 comprises upper standoffs, lower standoffs, right blinds, and left blinds. The upper standoffs and lower standoffs have glass openings and hollow sections located below the glass openings. Drainage gutters are provided continuously between the upper standoffs and lower standoffs within the hollow sections. The right standoffs and left blinds have glass openings, the longitudinal ends of which are located between the upper standoffs and lower standoffs. The bottom walls of the glass openings of the right standoffs and left blinds are lower than the bottom wall of the glass opening of the upper standoff, and their longitudinal ends face the drainage gutters. Water that enters the glass opening of the upper standoffs enters the glass openings of the blinds and then flows into the drainage gutters, and water that enters the glass openings of the blinds flows into the drainage gutters. This eliminates the need to seal the gaps between the longitudinal ends of the standoffs and blinds, making installation easy. Furthermore, any water that gets into the glass openings of the mullion or the blind glass openings is drained without leakage through a drainage gutter installed inside the hollow part of the mullion, making it highly waterproof.

方立１は、図４，５，６に示すように、無目２の水上側と水下側で上方立１ａと下方立１ｂとに分割されており、上方立１ａの水下側端部と下方立１ｂの水上側端部との間には、間隔２４が設けてある。上方立１ａの水下側端部は、図６に示すように、ガラス間口３，３の底壁４よりも下の部分が切り欠かれている。下方立１ｂの水上側端部には、図４～６に示すように、ガラス間口３，３の底壁４と底壁４から立ち上がる突部２５とにわたって切欠き２６が設けてある。
上方立１ａの中空部５内に設けられた排水樋６ａは、図６に示すように、水下側端部が無目２を超えて下方立１ｂの中空部５内までのびており、その上方立１ａの排水樋６ａの水下側端部が下方立１ｂの中空部５内に設けられた排水樋６ｂの水上側端部と下方立１ｂの中空部５内で接続部材２７により接続している。これにより、上方立１ａの排水樋６ａと下方立１ｂの排水樋６ｂを連続させている。
接続部材２７は、ゴム又は樹脂で形成してあり、排水樋６ａ，６ｂの周囲を囲むように断面コ字型に形成してあり、水上側寄りの内面に湿式のシール材２８を充填するための凹部２９が設けてある。この接続部材２７は、下方立１ｂの排水樋６ｂの水上側端部に接着剤等であらかじめ取付けられており、接続部材２７の内側に上方立１ａの排水樋６ａの水下側端部を差し入れ、図５，６に示すように、上方立１ａの排水樋６ａの水下側の小口と下方立１ｂの排水樋６ｂの水上側の小口との間に内周側から湿式のシール材２８を充填し、排水樋６ａ，６ｂ同士を繋いでいる。接続部材２７に凹部２９が設けてあることで、シール材２８は上方立１ａの排水樋６ａの外周側に回り込んでいる。下方立１ｂの水上側端部に切欠き２６が設けてあるのは、このシール材２８の充填を行うためである。
As shown in Figures 4, 5, and 6, the mullion 1 is divided into an upper mullion 1a and a lower mullion 1b on the above-water and below-water sides of the transom 2, and a gap 24 is provided between the below-water end of the upper mullion 1a and the above-water end of the lower mullion 1b. As shown in Figure 6, the below-water end of the upper mullion 1a is cut out below the bottom wall 4 of the glass openings 3, 3. As shown in Figures 4 to 6, a notch 26 is provided at the above-water end of the lower mullion 1b, spanning the bottom wall 4 of the glass openings 3, 3 and a protrusion 25 rising from the bottom wall 4.
As shown in Figure 6, the drain gutter 6a provided within the hollow section 5 of the upper stand 1a has its underwater end extending beyond the crossbeam 2 into the hollow section 5 of the lower stand 1b, and the underwater end of the drain gutter 6a of the upper stand 1a is connected to the abovewater end of the drain gutter 6b provided within the hollow section 5 of the lower stand 1b by a connecting member 27 within the hollow section 5 of the lower stand 1b. This makes the drain gutter 6a of the upper stand 1a and the drain gutter 6b of the lower stand 1b continuous.
The connecting member 27 is made of rubber or resin and has a U-shaped cross section that surrounds the drainage gutters 6a and 6b.

The belowwater end of the drainage gutter 6a of the upper riser 1a is inserted inside the connecting member 27, and as shown in Figures 5 and 6, wet sealant 28 is filled from the inner periphery between the belowwater end of the drainage gutter 6a of the upper riser 1a and the abovewater end of the drainage gutter 6b of the lower riser 1b, connecting the drainage gutters 6a and 6b. The recess 29 in the connecting member 27 allows the sealant 28 to wrap around the outer periphery of the drainage gutter 6a of the upper riser 1a. The notch 26 at the abovewater end of the lower riser 1b is provided for filling with the sealant 28.
無目２は、図４，５，７に示すように、方立１の左右で右無目２ａと左無目２ｂとに分割されている。右無目２ａの長手方向端部と左無目２ｂの長手方向端部には、図７に示すように、ガラス間口７，７の底壁８より下側に切欠き３０が設けてあると共に、図５に示すように、水上側のガラス間口７の水上側の壁に切欠き３１が設けてある。
右無目２ａの左側端部と左無目２ｂの右側端部は、図４，５に示すように、上方立１ａの水下側端部と下方立１ｂの水上側端部との間の間隔２４に進入させてあり、上方立１ａのガラス間口３，３の水下側端部が右無目２ａ及び左無目２ｂの水上側のガラス間口７に入り込んでいる。さらに、図７に示すように、右無目２ａ及び左無目２ｂのガラス間口７，７の底壁８の長手方向端部が、排水樋６（上方立１ａの排水樋６ａ）に臨ませてある。右無目２ａ及び左無目２ｂのガラス間口７，７の底壁８の下面には、排水樋６の内側の位置に水切溝３３が設けてある。
As shown in Figures 4, 5 and 7, the gable 2 is divided into a right gable 2a and a left gable 2b on the left and right sides of the mullion 1. As shown in Figure 7, the longitudinal end of the right gable 2a and the longitudinal end of the left gable 2b have a notch 30 below the bottom wall 8 of the glass openings 7, 7, and as shown in Figure 5, a notch 31 is provided in the above-water wall of the above-water side glass opening 7.
As shown in Figures 4 and 5, the left end of the right blind 2a and the right end of the left blind 2b extend into the gap 24 between the belowwater end of the upper blind 1a and the abovewater end of the lower blind 1b, and the belowwater end of the glass openings 3, 3 of the upper blind 1a extends into the abovewater glass openings 7 of the right blind 2a and left blind 2b. Furthermore, as shown in Figure 7, the longitudinal ends of the bottom walls 8 of the glass openings 7, 7 of the right blind 2a and left blind 2b face the drainage gutter 6 (the drainage gutter 6a of the upper blind 1a). A drainage groove 33 is provided on the underside of the bottom walls 8 of the glass openings 7, 7 of the right blind 2a and left blind 2b, located inside the drainage gutter 6.
方立１と無目２の交差部は上記のように構成してあり、図５，６に示すように、上方立１ａのガラス間口３，３の底壁４上を流下した雨水３２ａは、右無目２ａ及び左無目２ｂの水上側のガラス間口７に入り、その後に同ガラス間口７から排水樋６に入り、方立１の中空部５内に連続して設けた排水樋６を通じて排水される。右無目２ａ及び左無目２ｂのガラス間口７，７に入った雨水３２ｂは、長手方向端部から排水樋６に流れ、方立１の中空部５内に連続して設けた排水樋６を通じて排水される。無目２ａ，２ｂのガラス間口７，７の底壁８の下面の排水樋６上の位置に水切溝３３が設けてあることで、雨水３２ｂがガラス間口７，７の底壁８の下面を伝って排水樋６の外側に出るのを防止できる。したがって、ガラス９回りのシールが切れて方立１及び無目２のガラス間口３，７に雨水３２ａ，３２ｂが浸入したとしても、その雨水は漏れなく排水樋６を通じて水下側に排水され、雨水が下に落ちることがない。 The intersection of the mullion 1 and the gable 2 is configured as described above, and as shown in Figures 5 and 6, rainwater 32a flowing down the bottom wall 4 of the glass openings 3, 3 of the upper mullion 1a enters the glass openings 7 above the water in the right gable 2a and left gable 2b, then enters the drainage gutter 6 from the glass openings 7 and is drained through the drainage gutter 6 that is provided continuously within the hollow portion 5 of the mullion 1. Rainwater 32b that enters the glass openings 7, 7 of the right gable 2a and left gable 2b flows from the longitudinal ends into the drainage gutter 6 and is drained through the drainage gutter 6 that is provided continuously within the hollow portion 5 of the mullion 1. A drainage groove 33 is provided on the underside of the bottom wall 8 of the glass openings 7, 7 of the gable 2a, 2b, above the drainage gutter 6, preventing rainwater 32b from flowing down the underside of the bottom wall 8 of the glass openings 7, 7 and leaking out of the drainage gutter 6. Therefore, even if the seal around the glass 9 breaks and rainwater 32a, 32b seeps into the glass openings 3, 7 of the mullion 1 and gable 2, the rainwater will be drained downstream through the drainage gutter 6 without leaking, and will not fall below.
次に、本トップライトの施工手順を説明する。まず、下方立１ｂの排水樋６ｂの水上側端部に接続部材２７をあらかじめ取付けておき、上方立１ａの排水樋６ａの水下側端部を接続部材２７に差し入れながら、上方立１ａと下方立１ｂを所定の間隔２４をあけて配置する。
その後、上方立１ａの排水樋６ａと下方立１ｂの排水樋６ｂの小口同士の間に接続部材２７の内周側から湿式のシール材２８を充填し、排水樋６ａ，６ｂを連続させる。
次に、右無目２ａと左無目２ｂの長手方向端部を上方立１ａと下方立１ｂの間の間隔２４に進入させ、ガラス間口７，７の底壁８の長手方向端部を排水樋６にのぞませて配置する。
全ての方立１と無目２を配置したら、方立１と無目２とで形成された各開口部にガラス９を上方から配置する。
その後、方立１と無目２に押縁１２，２１を取付け、ガラス９上面と押縁１２，２１との隙間に湿式のシール材１４を充填し、ガラス９を固定する。
Next, the construction procedure for this skylight will be explained. First, the connecting member 27 is attached to the above-water end of the drainage gutter 6b of the lower stand 1b in advance, and the below-water end of the drainage gutter 6a of the upper stand 1a is inserted into the connecting member 27, while the upper stand 1a and the lower stand 1b are positioned with a predetermined distance 24 between them.
Thereafter, a wet sealing material 28 is filled between the ends of the drainage gutter 6a of the upper stand 1a and the drainage gutter 6b of the lower stand 1b from the inner side of the connecting member 27, thereby connecting the drainage gutter 6a, 6b.
Next, the longitudinal ends of the right and left transoms 2a and 2b are inserted into the gap 24 between the upper and lower transoms 1a and 1b, and the longitudinal ends of the bottom walls 8 of the glass openings 7, 7 are positioned so that they face the drainage gutter 6.
After all the mullions 1 and the transoms 2 have been placed, glass 9 is placed from above in each opening formed by the mullions 1 and the transoms 2.
Thereafter, the battens 12, 21 are attached to the mullions 1 and the transoms 2, and a wet sealant 14 is filled into the gap between the upper surface of the glass 9 and the battens 12, 21 to fix the glass 9.
図８は、本発明のトップライトの他の実施形態を示している。以下、これまでに説明した実施形態と異なる部分について説明する。
方立１と無目２は、図８（ａ）に示すように、斜めに交差させて配置してある。そのため、上方立１ａと下方立１ｂと右無目２ａと左無目２ｂは、長手方向の端部を斜めに切断してある。
方立１の中空部内には、図８（ｃ）に示すように、第１実施形態と同様に排水樋６が設けてあり、この排水樋６はアルミニウム合金の押出形材で形成したものとなっている。排水樋６は、左右の側壁の外側面に溝状の嵌合部３４，３４が長手方向に沿って形成してあると共に、底壁の下面に帯状の突部３５が長手方向に沿って形成してある。
上方立１ａの排水樋６ａと下方立１ｂの排水樋６ｂとは、接続部材２７により連結してある。接続部材２７は、ゴム又は樹脂で形成した略コ字型断面の部材となっており、排水樋６の側面の嵌合部３４，３４と突部３５とに嵌合している。接続部材２７は、上方立１ａの排水樋６ａと下方立１ｂの排水樋６ｂのいずれか一方の端部にあらかじめ取付けておき、他方の端部を接続部材２７に長手方向から嵌合させて取付ける。
Fig. 8 shows another embodiment of the skylight of the present invention. The following will explain the differences from the embodiments described so far.
As shown in Figure 8(a), the mullions 1 and 2 are arranged to cross each other diagonally. Therefore, the longitudinal ends of the upper mullions 1a, lower mullions 1b, right mullions 2a, and left mullions 2b are cut diagonally.
As shown in Figure 8(c), a drainage gutter 6 is provided in the hollow portion of the mullion 1, as in the first embodiment, and this drainage gutter 6 is made of an extruded aluminum alloy. The drainage gutter 6 has groove-like fitting portions 34, 34 formed along the longitudinal direction on the outer surfaces of the left and right side walls, and a strip-like protrusion 35 formed along the longitudinal direction on the underside of the bottom wall.
The drain gutter 6a of the upper stand 1a and the drain gutter 6b of the lower stand 1b are connected by a connecting member 27. The connecting member 27 is a member made of rubber or resin with a roughly U-shaped cross section, and fits into fitting portions 34, 34 and protrusion 35 on the side of the drain gutter 6. The connecting member 27 is attached in advance to one end of either the drain gutter 6a of the upper stand 1a or the drain gutter 6b of the lower stand 1b, and the other end is fitted into the connecting member 27 in the longitudinal direction to install it.
以上に述べたように本トップライトは、上方立１ａと、下方立１ｂと、右無目２ａと、左無目２ｂとを備え、上方立１ａと下方立１ｂは、ガラス間口３，３と、ガラス間口３，３の下方に位置する中空部５を有し、中空部５内に排水樋６が上方立１ａと下方立１ｂとに連続して設けてあり、右無目２ａと左無目２ｂは、ガラス間口７，７を有し、ガラス間口７，７の長手方向端部が上方立１ａと下方立１ｂの間に位置しており、右無目２ａと左無目２ｂのガラス間口７，７の底壁８は、上方立１ａのガラス間口３，３の底壁４よりも低い位置にあって、長手方向端部を排水樋６にのぞませてあり、上方立１ａのガラス間口３，３に入った水３２ａが無目２ａ，２ｂのガラス間口７に入ってから排水樋６に流れ、無目２ａ，２ｂのガラス間口７，７に入った水３２ｂが排水樋６に流れるので、方立１ａ，１ｂ及び無目２ａ，２ｂの長手方向端部同士の隙間をシールする必要がなく、施工性が良い。しかも、方立１ａ，１ｂのガラス間口３，３に入った水、無目２ａ，２ｂのガラス間口７，７に入った水が、漏れなく方立１の中空部５内に設けた排水樋６を通じて排水されるため、止水性にも優れている。
排水樋６は、方立１とは別体で形成してあるので、方立１と排水樋６を別々に切断して組み合わせることで、容易に施工することができる。
排水樋６は、ゴム製又は樹脂製とすることで、方立１が途中で少し折れ曲がっていたり湾曲したりする場合でも、排水樋６がその折れ曲がり等に応じて変形するため、容易に施工することができる。
無目２ａ，２ｂは、長手方向の端部のガラス間口７，７の底壁８の裏面に水切溝３３が設けてあることで、雨水がガラス間口７，７の底壁８の裏面を伝って排水樋６の外側に流れるのを防止できる。
本トップライトは、上方立１ａの排水樋６ａの水下側端部と下方立１ｂの排水樋６ｂの水上側端部を接続部材２７により連続させているので、排水樋６を上方立１ａと下方立１ｂとに連続して設けるのが容易である。
また本トップライトは、上方立１ａの排水樋６ａと下方立１ｂの排水樋６ｂの端部間を排水樋６の内周側からシールしてあるので、排水樋６の継ぎ目から水が漏れるのを確実に防止できる。
As described above, this skylight comprises upper stand 1a, lower stand 1b, right blind 2a and left blind 2b, and upper stand 1a and lower stand 1b have glass openings 3, 3 and a hollow portion 5 located below the glass openings 3, 3, and a drainage gutter 6 is provided within hollow portion 5 to connect upper stand 1a and lower stand 1b, right blind 2a and left blind 2b have glass openings 7, 7, and the longitudinal ends of the glass openings 7, 7 are located between upper stand 1a and lower stand 1b, and right blind 2a and left blind The bottom wall 8 of the glass openings 7, 7 of mullions 1a and 2b is located lower than the bottom wall 4 of the glass openings 3, 3 of the upper mullion 1a, and its longitudinal ends face the drainage gutter 6. Water 32a that enters the glass openings 3, 3 of the upper mullion 1a enters the glass openings 7 of the mullion 2a and 2b and then flows into the drainage gutter 6, and water 32b that enters the glass openings 7, 7 of the mullion 2a and 2b flows into the drainage gutter 6. This eliminates the need to seal the gaps between the longitudinal ends of the mullions 1a, 1b and the mullion 2a, 2b, making installation easy. Moreover, water that enters the glass openings 3, 3 of the mullions 1a and 1b and the glass openings 7, 7 of the mullion 2a and 2b is drained without leakage through the drainage gutter 6 installed in the hollow part 5 of the mullion 1, resulting in excellent watertightness.
The drainage gutter 6 is formed separately from the upright 1, so that the construction can be easily carried out by cutting the upright 1 and the drainage gutter 6 separately and combining them.
By making the drainage gutter 6 from rubber or resin, even if the mullion 1 is slightly bent or curved midway, the drainage gutter 6 can be deformed according to the bending or the like, and construction can be easily performed.
The gutter 2a, 2b are provided with a water drain groove 33 on the back surface of the bottom wall 8 of the glass opening 7, 7 at the end in the longitudinal direction, thereby preventing rainwater from flowing down the back surface of the bottom wall 8 of the glass opening 7, 7 to the outside of the drainage gutter 6.
In this skylight, the below-water end of the drainage gutter 6a of the upper tier 1a and the above-water end of the drainage gutter 6b of the lower tier 1b are connected by a connecting member 27, making it easy to install the drainage gutter 6 continuously in the upper tier 1a and the lower tier 1b.
In addition, this skylight has the ends of the drainage gutter 6a of the upper stand 1a and the drainage gutter 6b of the lower stand 1b sealed from the inner periphery of the drainage gutter 6, so water can be reliably prevented from leaking from the joints of the drainage gutter 6.
