Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a skylight used in the main or sub-roof, or the roof of a sunroom, greenhouse, assembly house, etc. The present invention relates to a drainage structure in a multi-window skylight in which skylight bodies are arranged on a skylight frame, adjacent to each other in the left-right direction and inclined in the vertical direction.

(Prior art and its problems) In general, in this type of skylight, the skylight body rattles due to wind pressure during rain accompanied by strong winds, and gaps are created between the skylight bodies or between each skylight body and the skylight frame. Rainwater can sometimes enter through such gaps, but because conventional skylights do not have a special drainage structure, the rainwater that has entered cannot be avoided from leaking indoors as described above.

(Technical means for solving the problem) In view of the above, the present invention aims to prevent rainwater that has entered the inside of a skylight from leaking indoors, and the present invention provides technical means in accordance with this purpose. The lower side stile, the lower side stile, and the left and right side fences are framed in a rectangular shape to form a skylight frame, and the intermediate stile is interposed between the lower side stile and the lower side stile parallel to the left and right side frames. The above-mentioned skylight frame is divided into a plurality of skylight frame parts, each of the above-mentioned skylight bodies is mounted on each skylight frame part, and the inside of each of the above-mentioned lower side stile, lower side stile, left and right side fences, and intermediate stile is divided. A gutter groove is provided along the entire longitudinal length of each frame, and the gutter groove in the intermediate stile faces directly below the boundary between the adjacent skylight bodies,
The upstream end of this gutter groove is connected to the gutter groove in the upper side stile, and the downstream end is connected to the outside of the lower side stile so that water can drain, and the gutter groove in each of the left and right side frames is connected. is connected to the gutter groove in the lower side stile, and furthermore, the drainage groove in the lower side stile can drain water to the outside of the lower side stile.

(Example) Next, an example in which a skylight according to the present invention is installed on the entire roof of a sunroom, for example, will be described based on FIGS. 1 to 6.

In these figures, reference numeral 1 denotes a continuous skylight, and as is clear from Fig. 1, it consists of three skylight sections 2a + 2b and 2c that are adjacent to each other in the left and right direction and are connected in a row with an inclination in the vertical direction. The skylight parts 2a, 2b, 2c are the skylight main body 3
