Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a skylight device for daylighting, in which a skylight body is attached to an opening in a building to let in light.

"Prior Art" Conventional skylights for daylighting have become widely popular in recent years because of their high efficiency in letting in light from the roof surface.

However, if the building is open and has sufficient ventilation, condensation is not inevitable with skylights for daylight, but in recent years, with the spread of heating and cooling, and many buildings are closed, condensation can occur in areas that are easily affected by outside temperature. Cheap. The applicant has previously developed a hemispherical skylight in which a flat inner body is provided on the lower surface of the skylight body. in this case,
The central part of the skylight body is far away from the interior body, and this acts as a heat insulating layer and does not cause much condensation. However, at the periphery, the distance between the skylight body and the interior body is short and the insulation effect is low, so the interior body Condensation tends to form on the lower surface of the periphery, and as this condensation gradually increases, it loses its adhesion and falls, and this moisture can cause problems for articles, machinery, etc. inside the building.

``Problem that the invention attempts to solve'' If such condensed water is not prevented from falling,
One way to prevent this is to install a condensation catcher on the mounting bracket that attaches the interior body, as this can cause various problems, but if the condensation catcher is narrow, the condensation that falls outside of it will fall downwards, making it wider. This improves the probability of catching dew condensation, but on the other hand, the daylighting area becomes smaller and the daylighting efficiency deteriorates, so it can be said that it is better to prevent condensation from occurring than to provide a condensation catcher.

"Means for Solving Problems" This invention was devised to achieve such an objective, and its gist is to attach the main body of the skylight to the top of the mounting frame fixed to the opening of the building. At the same time, place the interior body whose size is approximately equal to the area of the opening of the building on the horizontal part of the mounting frame that extends toward the indoor side of the mounting frame, and in this state, connect the skylight body and the interior body. A skylight device for daylighting, characterized in that a sheet heating element is attached to the peripheral edge of the interior body near the mounting frame, and further, the sheet heating element is made of a light-transmitting material. It is characterized by having a certain

Next, the present invention will be explained with reference to drawings of embodiments.
What is shown in FIG. 1 is a part of a lighting skylight device installed in an opening of a building, and is an opening provided in the roof of one building. Reference numeral 2 denotes a metal mounting frame made of aluminum or steel, and a vertical part 3 has a slightly downwardly downwardly sloped part 4 formed halfway outside, and a hanging part 5 formed at the end thereof. A horizontal part 6 is provided on the opposite side to the inclined part 4,
A rising portion 7 is formed at the end thereof, and a horizontal receiving portion 8 is provided at the upper end of the vertical portion 3. The mounting frame 2 has an inclined part 4 placed on the outside from the upper surface of the opening 1 through a waterproof material 9 made of bituminous material, synthetic resin, etc., and is opened from the lower end of the vertical part 3 with screws 10 or the like. It is stuck to part 1. Reference numeral 11 denotes an interior body, and the upper part is a simple transparent plate 12 made of glass, synthetic resin, etc., and the lower part is a wired transparent plate 13 made of wired glass or synthetic resin, etc., and packing 14 is provided on the periphery of both. is polymerized through the polymerization gap 15
is formed. The periphery of such an interior body 11 is placed on the horizontal portion 6 of the mounting frame 2 via a packing 16. Reference numeral 17 denotes a packing 17 that is placed across the vertical part 3 of the mounting frame 2 and the periphery of the interior body 11, and on top of that, a horizontal part of the periphery of the transparent or translucent skylight body 18 made of synthetic resin such as acrylic. 19 is placed thereon, and a screw 22 is screwed and fixed thereon via a packing 20 and a washer 21.
Reference numeral 23 is a planar heating element, which has a flat shape with a heating wire such as a nichrome wire embedded inside a transparent synthetic resin, etc., and has an adhesive layer 24 on one side to prevent the internal heat generation. A cord 25 is connected to the wire, and a plug 26 is attached to the end, which is adhered to the peripheral edge of the lower surface of the interior body 11 near the mounting frame via an adhesive layer 24. be. 27 is a coating material filled between the hanging portion 5 and the waterproof material 9.

Although the present invention has been described above based on an example, it is of course not limited to this example. For example, the interior body 11 can be constructed of wired glass or other light-transmitting material units, or the planar heating element 23 can be made of a light-transmissive material and installed over the entire surface of the interior body 11. .

"Operation" Since the present invention has the above-described structure, when the plug 26 is inserted into an outlet, the planar heating element 23 is heated, thereby heating the peripheral edge of the interior body 11 near the mounting frame. That is what it is.

"Effect of the invention" As described above, the interior body 11 at the peripheral edge of the skylight main body 18 near the mounting frame has a short distance from the skylight main body 18, has a poor insulation effect due to the air layer, and is affected by the outside temperature. However, since this part is heated and warmed by the planar heating element 23, no condensation occurs, and various adverse effects caused by condensation can be prevented, and it can be made at low cost. By making the planar heating element 23 translucent, there is no adverse effect on the lighting efficiency. Moreover, the present invention has the advantage that it can be easily installed on existing equipment.
