DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skylight in which a fixed frame is attached to an upper part of a roof opening of a roof and a shoji is attached to the fixed frame.

[0002]

2. Description of the Related Art Since the outer surface of a shoji of a skylight directly contacts the outside air, and the inner surface of a shoji faces the roof opening, dew condensation occurs on the inner surface of the shoji, and the condensed water forms water droplets from the roof opening. May fall indoors and contaminate floors and walls. For this reason, as disclosed in Japanese Utility Model Application Laid-Open No. 62-32130, a skylight is known in which a frame forming a shoji is made of a heat-insulating material so that dew condensation does not occur on the inner surface of the shoji.

[0003]

With the above-mentioned skylight,
Since the frame is made of expensive insulation material, the skylight becomes very expensive, and even if the frame is used as insulation material, condensation cannot be completely prevented from forming on the inner surface of the shoji screen, and some condensation will occur. Water may drop into the room from the roof opening as water droplets and stain floors and walls.

Accordingly, an object of the present invention is to provide a skylight capable of solving the above-mentioned problem.

And collects the condensed water from each space into the lower space B and drains it.
Can be drained out of the hole.

[0007]

[Embodiment] As shown in FIGS. 1 and 2, the lower part of a rectangular wooden frame 3 is inserted into a roof opening 2 of a roof 1 and attached thereto. The fixed frame 4 is attached, and the shoji 5 is hinged to the fixed frame 4.
It can be freely opened and closed to form a skylight. The wooden frame 3 is formed by framed a wooden frame 7 in a rectangular shape, and a projection 8 is formed near the upper inner periphery of each wooden frame 7, and the upper end surface has a stepped shape with a lower outer peripheral side to form a bottom mounting surface 9. have. The fixed frame 4 is an upper frame 1 facing the roof gradient direction.
0 and the lower frame 11 and the left and right frames 12 and 12 facing in a direction perpendicular to the roof gradient direction.
0, lower frame 11 and left and right frames 12 are hollow main body 1
3, having a hook-shaped lower inward piece 14, a rising portion 15, and an outer hanging portion 16, the inner vertical plate 13a of the main body 13 and the lower inward piece 14 constitute an upward concave groove 17, and Upper horizontal plate 1
A concave groove 18 is formed in each of the upper frame 10 and the lower frame 11, and the outer hanging portion 16 has a plate-like shape. The outer hanging portion 16 has a hollow shape that is vertically continuous. The upper frame 10, the lower frame 11, and the left and right frames 1
2 and 12 are framed in a rectangular frame shape, and each upward concave groove 17 is 4
The rainwater which has flowed continuously into each upward concave groove 17 is
Are drained to the outside through the drain hole 19 of the inner vertical plate 13a and the drain hole 20 of the lower horizontal plate 13c, and the lower inward piece 14 of each frame is attached to the lower mounting surface 9 of each wooden frame member 7 with screws 21. . The shoji 5 includes an upper frame 30 and a lower frame 31 facing the roof gradient direction, a left and right frame 32 facing the roof gradient direction at right angles,
32 in a frame assembly 33 in which 32 is framed in a rectangular frame shape.
, And the glass 34 is a multi-layer glass. Each of the frames is provided with a vertical inward piece 36 above and below the main body 35.
37 are integrally provided to form a shape having inward concave portions 38, and glass 34 is provided in each inward concave portion 38 with the upper and lower sealing materials 3.
It is mounted via 9, 40. When the upper frame 10 and the upper frame 30 are connected by the hinge 6 and the sash 5 is closed, the airtight material 41 continuously attached to the concave groove 18 of the rising portion 15 of each frame four times is inserted into the lower inward piece 36 of each frame. Upper transverse seal pieces 42 which are press-fitted to each other and mounted in the concave groove 18 of the hanging portion 16 of each frame,
The lower horizontal seal piece 43 and the left and right horizontal seal pieces 44 are pressed against the outer surface 7a of each frame. The upper seal piece 5 is provided in the concave groove 18 of the upper horizontal plate 13b of the main body 13 of the upper frame 10.
The upper seal piece 50 is pressed into contact with the upper lower surface of the glass 34 and the lower inward piece 37 of the upper frame 30 to press the upper frame 3.
0 and forms an upper space A between itself and the pressure contact portion of the airtight material 41, and a lower seal 51 is mounted in the concave groove 18 of the upper horizontal plate 13b of the main body 13 of the lower frame 11. The lower sealing piece 51 is pressed against the lower inward piece 37 of the lower frame 31 to cover the inner surface of the lower frame 31 and the airtight material 41
A lower space B is formed between the lower sealing piece 51 and the lower end of the lower seal piece 51 and the lower surface of the glass 34 is close to the lower space B. Side seal pieces 52 are attached to the concave grooves 18 of the upper horizontal plate 13b of the main body 13 of the left and right frames 12, and the lower seal pieces 5
Reference numeral 2 is in contact with the lower left and right side portions of the glass 34 to cover the inner side surfaces of the left and right frames 32, and forms a side space C between the glass 34 and the pressure contact portion of the airtight material 41.

As a result, dew condensation occurs on the inner surface of each frame constituting the frame assembly 33 of the shoji 5, that is, on the lower inward piece 37, and drops as dew water. The condensed water that has flowed down into the left and right side spaces C does not flow down or splash inside due to the upper, lower, and side seal pieces 50, 51, and 52, and collects in the lower space B. The drainage holes 53 formed in the upper horizontal plate 13b of the main body 13 and the drainage holes 20 are drained to the outside, and the inner surface of each frame constituting the frame assembly 33 is covered with each seal piece to provide heat insulation. And dew condensation described above hardly occurs. In addition, the rainwater that has entered from the press-contact portions of the airtight material 41 and the lower surface of each frame also removes the upper, lower, and side seal pieces 5 as described above.
O, 51 and 52 prevent the water from flowing down and splashing, and the water is drained to the outside in the same manner as described above. In the above embodiment, the upper seal piece 50 and the side seal piece 52 are pressed against the lower surface of the glass 34, but they may be close to each other. FIG. 3 and FIG. 4 show a second embodiment, in which the upward groove 1 of each frame is shown.
The inner seal member 60 made of a water-absorbing heat-insulating material such as a heat-insulating sponge is continuously attached to the glass 7 and the inner seal member 60 is pressed against the lower surface of the glass 34. If you do this,
Since the inside and outside can be insulated by the inner seal member 60 to block the cold outside air and the warm and humid inside air, the heat loss can be reduced and the amount of dew condensation can be reduced, and the dew condensation water can be absorbed by the inner seal member 60. The lower frame 1
The water can be drained to the outside through the drain holes 19 and 20.

[0009]

The upper seal piece 50, the lower seal piece 51, and the left and right seal pieces 52 prevent the dew condensation water generated on the inner surface of each frame constituting the frame assembly 33 of the shoji screen 5 from flowing down. Water can be reliably prevented from dropping into the room from the roof opening and soiling the floor and walls.Also, despite using ordinary inexpensive frames, each seal piece covers the inside surface of each frame. As a result, it is possible to provide an inexpensive skylight with excellent heat insulation and reduced occurrence of dew condensation. Condensed water can be collected in the lower space B from each space and drained to the outside from the drain holes. Since the inside and outside are thermally insulated by the inner seal member 60 and the heat loss can be reduced, the amount of dew condensation can be further reduced.
