Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a skylight provided on the roof of a building.

[Prior art]

Recently, houses and the like are often provided with openable skylights on their roofs for lighting and ventilation. One example is the one described in Japanese Utility Model Application Publication No. 58-179337. The skylight described in this publication is characterized by having a shoji screen that can be opened and closed and an insect screen that can be opened and closed, but the base frame, shoji screen, etc. that make up the skylight are made of aluminum shapes. Because the shoji is made of shoji, it has poor insulation properties and is prone to condensation.Also, the drainage structure for condensation generated on the shoji is incomplete, so there are problems such as condensed water scattering indoors when opening and closing the shoji. be.

[Purpose of invention]

This invention was developed to solve the above-mentioned problems, and its purpose was to provide a base frame with good insulation properties, and to provide sufficient measures for drainage of condensed water even if condensation occurs. To realize a skylight without the risk of condensed water scattering indoors.

[Summary of the idea]

In order to achieve the above object, the present invention provides a skylight in which a shoji screen is attached to a frame fixed to a window sill provided at the periphery of a roof opening so as to be openable and closable. By providing a drainage hole in the side frame, and further providing a condensation catcher on the inside of the frame member constituting the shoji, and providing a drainage hole in the frame member on the eave side, the occurrence of condensation can be prevented. If dew condensation occurs, a skylight is provided that allows condensed water to be discharged outdoors from the drain hole.

[Example of idea]

FIG. 1 is a longitudinal cross-sectional view of an embodiment of the present invention, and FIG. 2 is a cross-sectional view thereof. In both figures, A is a skylight, B
is a building. 1 is a window sill provided at the periphery of a roof opening 2 of building B; 11 to 11C are base frames made of synthetic resin, which are framed and fastened to the window sill 1. 12a and 12b are drain holes provided at the lower part of the rear side of the base frame 11 on the eave side, and 13 to 13c are drain holes provided in the bottom of the base frame 11 on the eave side.
These are dew condensation receptacles protruding inward from the rear surface of each of the parts 11c. 14-14c have mounting grooves 15-15c and 16-16c for watertight members on the front and rear edges, respectively.
The base frames 11 to 11c are respectively locked on the outdoor side of the base frames 11 to 11c, and the base frames 11 to 1
This is a wall frame member fixed with screws to metal reinforcing frames 17 to 17c arranged inside 1c.

Reference numeral 24 denotes a shoji, and a glass mounting part is formed inside the frame members 22 to 22c made of aluminum shapes, etc., and the outer peripheral wall is extended rearward from the rear surface and then bent inward, and has a water cut edge. 23-2
3c is formed. 24 to 24c are frame members 2
2 to 22c are groove-shaped condensation catchers provided on the inside of the rear surface, 25a and 25b are drain holes provided on the rear surface of the eave side frame member 22, and this shoji 21 is provided on the rear surface of the ridge side frame member 22a. The hinge 26 is rotatably supported by the hinge receiver 18 of the ridge side wall frame member 14a. Note that 27, 27b, and 27c are mounting grooves for watertight members provided on the rear surfaces of the frame members 22, 22b, and 22c. 28 is a framed frame member 22~
The glass plate 29 attached to the glass plate 22c is a wired glass plate attached to the frame members 22 to 22c on the indoor side of the glass plate 28, and both are watertightly attached to the frame members 22 to 22c by beads.

Reference numeral 31 denotes a roll screen door disposed so as to be able to be rolled up at the rear opening of the frame formed by the base frames 11 to 11c;
is a locking fitting, and 33 and 33a are switches for the shoji 21. 34 to 34c are watertight members that are fitted into the mounting grooves 15 to 15c of the wall frame members 14 to 14c and maintain watertightness with the shoji 21; 35 to 35b are the mounting grooves 1;
6 to 16c, and is a watertight member that maintains watertightness with the window sill 2. The watertight member 35 is provided with a drain hole 36. 37, 37b, 37c are fitted into mounting grooves 27, 27b, 27c provided on the rear surface of the frame members 22, 22b, 22c,
4, 14b, and 14c.

In the present invention configured as described above, when the locking fitting 32 is unlocked using, for example, a hook rod, the rods of the switches 33, 33a extend and the shoji 21 rotates in the direction of the arrow around the hinge 26, thereby opening the skylight. 21 is opened. At this time, by unfolding the roll screen door 31, insects and the like can be prevented from entering through the roof opening 2. Also, if you close the shoji 21 with the hook rod,
It will be locked automatically.

By the way, in the present invention, the glass plate 28 and the wired glass plate 29 are each attached watertightly by beads, and the shoji 21 is attached to the watertight member 3.
4 to 34c, so there is no risk of rainwater entering even in the event of rain, and the frame member 2
2 to 22c are extended rearward from the rear surface and then bent inward to form water cutting edges 23 to 23c, so that rainwater does not enter the room through the wall frame members 14 to 14c.

Moreover, since the frames 11 to 11c are made of synthetic resin, they have a greater heat insulating effect than those made of metal, and therefore condensation is less likely to occur. If condensation occurs on the shoji 21, the condensed water moves to the eaves side (left side in Figure 1) and drains from the condensation receivers 24 to 24c to the drain holes 25a and 2.
5b and is discharged to the outside. Furthermore, shoji 21
Condensed water that has fallen from the lower part of the frame 11-1
Since the condensation generated in 1c is discharged to the outside from the condensation receivers 13 to 13c through the drain holes 12a, 12b, and 36, the condensed water does not scatter indoors.

Although the embodiments of the present invention have been described above, the structure of each part is not limited to the above embodiments, and can be modified as appropriate without departing from the gist of the present invention.

[Effect of idea]

As is clear from the above explanation, in this invention, the frame supporting the shoji is made of synthetic resin with high heat insulation effect, so condensation is difficult to form, and even if condensation does occur, it can be easily removed from the condensation tray through the drain hole. Since it is discharged outside, there is no risk of it being scattered indoors, so it has great effects when implemented.
