Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a lighting tile that allows daylight to come in from the roof surface and attic ventilation at the same time.

[Background technology]

Conventionally, in order to let in light from the roof surface and to ventilate the attic, a cylindrical part 25 is provided protruding from the roof as shown in FIG. It is fixed at 26, and the cylindrical part 2
Japanese Utility Model Application Publication No. 15426/1983 provides a structure in which a ventilation passage 27 is formed between the roof 5 and the cap 24, which communicates the attic with the outside. However, in this conventional ventilation structure, the mounting frame 28 is first fixed to the upper end surface of the cylindrical portion 25 with the screws 26, and then the peripheral edge of the cap 24 is attached to the mounting piece 29 of the mounting frame 28 using the screws 26. The cap 24 is attached to the roof by fixing the cap 24 on the roof, and it requires screwing at multiple locations, resulting in poor workability.

[Purpose of invention]

The present invention has been developed in view of the above points, and it is an object of the present invention to easily and reliably attach a transparent cap to the roof without the need for screws in order to bring in light from the roof and ventilate the attic. The purpose of this invention is to provide a lighting tile that allows for

[Disclosure of invention]

That is, the lighting tile of the present invention has a metal tile main body 1
From the entire periphery of the lighting opening 2 formed in the cylindrical body 3
At the same time, a male threaded part 21 is carved on the outer periphery of this cylindrical body 3, a female threaded part 22 is formed on the inner periphery of a cylindrical transparent cap 4 whose top surface is closed, and the female threaded part 22 of this transparent cap 4 is formed. The transparent cap 4 is attached to the cylindrical body 3 by screwing onto the male threaded portion 21 of the cylindrical body 3, and the transparent cap 4 is attached to the outer periphery of the cylindrical body 3.
A ventilation passage 5 is formed between the inner periphery of the transparent cap 4 and the inside of the cylindrical body 3 to communicate with the outside of the transparent cap 4.The roof can be given a lighting function simply by covering it with tiles. A lighting section can be easily formed, and the attic space can be ventilated through the ventilation passage 5.

The present invention will be described in detail below based on illustrated embodiments. The lighting tile A is composed of a metal tile main body 1 and a transparent cap 4. A lighting opening 2 is formed in the tile main body 1, and a cylindrical body 3 stands up from the entire periphery of the lighting opening 2. This cylindrical body 3 is formed by engraving a part of the tile main body 1, or is welded to the lighting opening 2. The transparent cap 4 is made of a transparent material and is formed into a cylindrical shape whose top surface is closed. The inner diameter of the transparent cap 4 is the cylindrical body 3
It is larger than the external shape. Further, a female threaded portion 22 is formed on the inner periphery of the transparent cap 4, while a male threaded portion 21 is formed on the outer periphery of the cylindrical body 3. Ventilation passages 5 are recessed in the inner periphery of the transparent cap 4 at regular intervals in the circumferential direction and extending over the entire length in the vertical direction. When the transparent cap 4 is screwed onto the cylindrical body 3, the attic and the outside communicate with each other via the ventilation passage 5.

As shown in FIG. 2a, a lighting hole 12 is provided through the roof waterproof base material 10 and shedding material 11 at a desired lighting location. The lighting tile A is installed so that the lighting opening 2 is located in the lighting hole 12.
A waterproof packing material 13 or caulking material is packed between the base of the cylindrical body 3 and the field material 11. B is a normal metal tile. Figures 3a and 3b show ceiling lighting units. A lighting window mounting hole 15 is formed in the ceiling 14 at a portion facing the lighting tile A, and a lighting window frame 16 is fitted into the lighting window mounting hole 15 with bolts 17. The transparent lighting window 18 is fitted into the lighting window frame 16. Reference numeral 19 denotes a light-shielding plate, which is fixed to an operating rod 20 rotatably attached to the daylighting window frame 16. When the operating stick 20 is rotated, it rotates in the direction of the arrow in FIG. It covers 18.

[Effect of idea]

As mentioned above, the present invention has a cylindrical body raised from the entire periphery of the lighting opening of the metal tile body, and a gap between the outer periphery of the cylindrical body and the inner periphery of the transparent cap that is connected to the inside of the cylindrical body and the transparent cap. Since we have formed a ventilation passage that communicates with the outside of the cap, when this lighting tile is installed on the roof, the attic and the outside of the roof can be communicated through the ventilation passage of the lighting tile, and the ventilation of the ceiling is improved. This has the advantage of allowing light to pass through the transparent cap and let in light from the roof surface. Moreover, rainwater flowing down on the roof tiles is not obstructed by the cylindrical body and enters the attic through the lighting opening, eliminating the need for complicated rainwater removal work. In addition, a male thread is carved on the outer periphery of the cylindrical body formed by standing up on the tile body, and a female thread is formed on the inner periphery of the transparent cap, and the female thread of the transparent cap is screwed into the male thread of the cylindrical body. Then, a transparent cap was attached to the cylindrical body, and a ventilation passageway was formed between the outer periphery of the cylindrical body and the inner periphery of the transparent cap, allowing communication between the inside of the cylindrical body and the outside of the transparent cap. The transparent cap can be attached to the cylindrical body simply by screwing the female threaded part of the transparent cap onto the male threaded part of the cylindrical body. It has the advantage that it can be screwed onto the body and there is no need to worry about the transparent cap being blown away by wind pressure.
