DETAILED DESCRIPTION OF THE INVENTION

[0007] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Figures 1 to 7 show one embodiment of a skylight of the present invention. This skylight forms the roof of an atrium space, and as shown in Figure 3, mullions 1, 1, ... and transoms 2, 2, ... are arranged in a grid pattern, and glass 9 is attached to each opening formed by the mullions 1 and transoms 2, allowing light to enter from the entire roof. As shown in Figures 1 and 3, the mullion 1 is arranged at an angle so that its underwater side is lower. The mullion 1 is not strictly straight, but rather its angle gradually becomes steeper as it approaches the underwater side. The mullions 1 and transoms 2 are fixed to a frame 11 with fasteners 10.

[0008] The mullion 1 is made of extruded aluminum alloy material, and as shown in Figure 2, has glass openings 3,3 at the top of its cross section that hold the side edges of the glass panes 9,9 arranged on both the left and right sides of the mullion 1. The top wall of the glass openings 3,3 is made up of a removable ledge 12. The underside of the glass panes 9 is supported by a pre-attached bead 13, and they are held in place by filling a wet sealant 14 between the top surface of the glass panes 9 and the ledge 12. Rainwater that seeps into the glass openings 3,3 flows from the above-water side to the below-water side on the bottom wall 4 of the glass openings 3,3. A rectangular hollow 5 is provided below the glass openings 3,3 of the mullion 1, and a drainage gutter 6 is provided within the hollow 5 along the longitudinal direction. The drainage gutter 6 is made of rubber or resin and has a U-shaped cross section with left and right side walls and a bottom wall. Locking portions 15,15 formed on the upper ends of the side walls are engaged with locking grooves 16,16 with a roughly C-shaped cross section formed on the underside of the bottom wall 4 of the glass openings 3,3, so that the drainage gutter is attached in a suspended form in the center of the left and right direction of the bottom wall 4 of the glass openings 3,3. Furthermore, a steel reinforcing member 17 is provided within the hollow 5 along its entire length. A bolt holding groove 19 for holding the head of a bolt 18 is provided along the longitudinal direction on the underside of the mullion 1, and the bolt 18 held in the bolt holding groove 19 and a nut 20 attach the mullion 1 to the fastener 10.

[0009] The transom 2 is formed from an extruded aluminum alloy profile, just like the mullion 1, and as shown in Figure 1, has at the top of its cross section the underwater edge of the glass 9 that is placed above the water and glass openings 7,7 that hold the abovewater edge of the glass 9 that is placed below the water. The upper walls of the glass openings 7,7 are made up of a removable ledge 21. The underside of the glass 9 is supported by a pre-attached bead 13, and is held in place by filling a wet sealant 14 between the top surface of the glass 9 and the ledge 21. The bottom wall 8 of the glass openings 7,7 of the transom 2 is located lower than the bottom wall 4 of the glass openings 3,3 of the mullion 1. Below the glass openings 7, 7 of the transom 2, a hollow portion 22 of rectangular cross section is provided, and a steel reinforcing member 23 is provided in the hollow portion 22 along its entire length. A bolt holding groove 19 for holding the head of a bolt 18 is provided along the longitudinal direction on the underside of the mullion 2, and the bolt 18 held in the bolt holding groove 19 and a nut 20 attach the mullion 2 to the fastener 10. The underside of the mullion 2 and the underside of the mullion 1 are located on the same plane.

[0010] 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 glazed glass 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, the above-water end of the lower mullion 1b has a notch 26 that extends from the bottom wall 4 of the glass openings 3,3 to a protrusion 25 rising from the bottom wall 4. As shown in Figure 6, the drainage gutter 6a provided within the hollow section 5 of the upper stand 1a has its underwater end extending beyond the mullion 2 into the hollow section 5 of the lower stand 1b, and the underwater end of the drainage gutter 6a of the upper stand 1a is connected to the abovewater end of the drainage 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 drainage gutter 6a of the upper stand 1a and the drainage 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. A recess 29 is provided on the inner surface near the abovewater side for filling with a wet sealant 28. This connecting member 27 is pre-attached with adhesive or the like to the abovewater end of the drainage gutter 6b of the lower stand 1b. The belowwater end of the drainage gutter 6a of the upper stand 1a is inserted inside the connecting member 27. 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 stand 1a and the abovewater end of the drainage gutter 6b of the lower stand 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 stand 1a. The notch 26 at the abovewater end of the lower stand 1b is provided for filling with the sealant 28.

[0011] As shown in Figures 4, 5, and 7, the gutter 2 is divided into a right gutter 2a and a left gutter 2b on the left and right sides of the mullion 1. As shown in Figure 7, the longitudinal end of the right gutter 2a and the longitudinal end of the left gutter 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 gutter 2a and the right end of the left gutter 2b extend into the gap 24 between the belowwater end of the upper bay 1a and the abovewater end of the lower bay 1b, and the belowwater end of the glass openings 3,3 of the upper bay 1a extends into the abovewater glass openings 7 of the right gutter 2a and left gutter 2b. Furthermore, as shown in Figure 7, the longitudinal ends of the bottom walls 8 of the glass openings 7,7 of the right gutter 2a and left gutter 2b face the drainage gutter 6 (the drainage gutter 6a of the upper bay 1a). A drainage groove 33 is provided on the underside of the bottom walls 8 of the glass openings 7,7 of the right gutter 2a and left gutter 2b, located inside the drainage gutter 6.

[0012] The intersection of the mullions 1 and 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 of the right mullions 2a and left mullions 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 part 5 of the mullion 1. Rainwater 32b that enters the glass openings 7, 7 of the right mullions 2a and left mullions 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 part 5 of the mullion 1. A water drain groove 33 is provided on the underside of the bottom wall 8 of the glass openings 7, 7 of the mullions 2a and 2b, above the drainage gutter 6, thereby 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 the gable 2, the rainwater is drained downstream without leakage through the drainage gutter 6 and does not fall below.

[0013] Next, we will explain the installation procedure for this skylight. First, attach the connecting member 27 to the above-water end of the drainage gutter 6b of the lower stand 1b in advance, and then insert the below-water end of the drainage gutter 6a of the upper stand 1a into the connecting member 27, while arranging the upper stand 1a and the lower stand 1b with a specified 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 periphery side of the connecting member 27, thereby connecting the drainage gutter 6a, 6b. Next, the longitudinal ends of the right transom 2a and left transom 2b are inserted into the gap 24 between the upper rafter 1a and the lower rafter 1b, and the longitudinal ends of the bottom wall 8 of the glass openings 7,7 are positioned so that they face the drainage gutter 6. Once all the mullions 1 and lattices 2 have been placed, glass 9 is placed from above into each opening formed by the mullions 1 and lattices 2. Thereafter, the battens 12, 21 are attached to the mullions 1 and the lintels 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 in place.

[0014] Fig. 8 shows another embodiment of the skylight of the present invention. The following describes 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 profile. 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-shaped 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 the 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 attached by fitting it into the connecting member 27 from the longitudinal direction.

[0015] As described above, this skylight comprises upper stand 1a, lower stand 1b, right blind 2a, and left blind 2b. Upper stand 1a and lower stand 1b have glass openings 3, 3 and a hollow section 5 located below glass openings 3, 3. A drainage gutter 6 is provided within hollow section 5, continuing from upper stand 1a and lower stand 1b. Right blind 2a and left blind 2b have glass openings 7, 7, and the longitudinal ends of glass openings 7, 7 are located between upper stand 1a and lower stand 1b. Right blind 2a and left blind 2b The bottom wall 8 of the glass openings 7,7 of 2b is located lower than the bottom wall 4 of the glass openings 3,3 of the upper stand 1a, and its longitudinal ends face the drainage gutter 6. Water 32a that enters the glass openings 3,3 of the upper stand 1a enters the glass openings 7 of the glazed glass 2a, 2b and then flows into the drainage gutter 6, and water 32b that enters the glass openings 7,7 of the glazed glass 2a, 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 glazed glass 2a, 2b, making installation easy. Moreover, the water that enters the glass openings 3,3 of the mullions 1a, 1b and the glass openings 7,7 of the glazed glass 2a, 2b is drained without leakage through the drainage gutter 6 installed in the hollow part 5 of the mullion 1, making it also excellent in 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 assembling them together. By making the drainage gutter 6 from rubber or resin, even if the mullion 1 is slightly bent or curved halfway, the drainage gutter 6 can be deformed according to the bending or the like, making it easy to install. The gutter 2a, 2b are provided with a water drain groove 33 on the backside of the bottom wall 8 of the glass opening 7, 7 at the longitudinal end, thereby preventing rainwater from flowing down the backside 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 rafter 1a and the drainage gutter 6b of the lower rafter 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.

[0016] The present invention is not limited to the above-described embodiments. The cross-sectional shape and material of the mullion and the transom can be changed as needed. The cross-sectional shape and material of the drainage gutter can also be changed as needed. The drainage gutter can also be provided integrally with the mullion. [Explanation of symbols]
