2. Description of the Related Art A vertical frame or a horizontal frame of a window frame of an inclined skylight generally has a substantially rectangular tube-shaped frame body on which an end portion of a window glass is placed, and is mounted on the frame body. Since it is composed of a glass holding frame that holds the edge of the window glass with elastic packing between the frame body and the frame body, the upper surface of the window glass is considerably lower than the upper surface of each vertical and horizontal frame, and both A step is formed between them, and therefore rainwater is likely to collect at the step between the upper surface of the window glass and the intermediate horizontal frame or the lower horizontal frame located downstream thereof, and drainage of the rainwater becomes a problem.

However, when the window surface of the inclined skylight has a steep inclination of about 40 degrees or more, caulking is performed between the window glass and the intermediate horizontal frame or the lower horizontal frame located at the downstream end thereof. If the material is loaded so that its upper surface presents a substantially horizontal surface and the step is eliminated, rainwater can be discharged from the upper surface of the caulking material over the upper surface of the horizontal frame to the downstream side or outside the skylight. You can However, if the window surface has a gentle inclination of, for example, about 10 degrees, and if the caulking material is loaded by the above method to eliminate the step portion, the cross-sectional area of the step portion is considerably large. In addition, since a very large amount of caulking material is required and the caulking material covers a wide area of the window glass, it is not preferable in terms of the function of the skylight and in appearance.

In view of the above circumstances, the present invention provides an inclined skylight without using a caulking material that fills a step between the window glass and the intermediate horizontal frame and / or the lower horizontal frame. It is an object of the present invention to provide an inclined skylight that can effectively drain rainwater and the like to the downstream side by utilizing it.

In addition, elastic packings 27 are attached to both ends of the lower surface of the glass pressing frame 18.
A caulking material 28 is loaded between the window 8 and the left and right ends of the window glasses 6, 7.

Although not shown in the drawings for attaching the lower end portion of the downstream window glass 7 to the lower horizontal frame 3, the lower horizontal frame 3 is a generally used conventional horizontal frame, and the downstream side window glass 7 is also used. As shown in FIG. 1, is a steeply inclined vertical frame 5 having an inclination angle β.
Since a steep slope is formed by being supported on the downstream side window 3, the caulking material is loaded in the step portion between the lower horizontal frame 3 and the downstream side window glass 7 so that the upper surface of the caulking material becomes horizontal. Rainwater flowing down the glass 7 can be discharged to the outside from the upper surface of the caulking material along the upper surface of the lower horizontal frame 3.

According to the skylight having the above structure,
As shown in FIG. 1, rainwater during rain (or cleaning water for cleaning the skylight) flows down on the upper surface of the upstream side window glass 6 having a gentle inclination, and the drainage channel of the protruding frame portion 9 in the intermediate horizontal frame 2 is discharged. 10 and then discharged onto the downstream window glass 7. That is, the rainwater flowing down on the upper surface of the upstream side window glass 6 flows into the hollow frame portion 12 forming the drainage channel 10 through the inflow port 13 and passes through the bottom wall (partition wall 11) of the hollow frame portion 12. Is discharged from the outlet 14 onto the window glass 7 on the downstream side. Therefore, rainwater does not collect in the stepped portion between the lower end portion of the upstream side window glass 6 having a gentle inclination and the intermediate horizontal frame 2.

On the steeply sloped downstream window glass 7, rainwater flowing down from the upper side of the caulking material loaded in the step between the downstream window glass 7 and the lower horizontal frame 3 as described above. After passing over the upper surface of the lower horizontal frame 3, it is discharged to the outside of the skylight.

In this embodiment, the window is a skylight having an intermediate horizontal frame, in which the upstream window glass is installed in a gentle inclination with an inclination angle of about 10 degrees, and the downstream window glass is provided. An example in which the structure of the present invention is applied to the middle horizontal frame of a skylight with a steep inclination of 40 degrees or more has been described, but the window frame does not have the middle horizontal frame. In the case of a skylight in which the window glass is entirely installed in the frame with a gentle inclination, the configuration of the present invention may be adopted for the lower horizontal frame. Further, in the case of a skylight having an intermediate horizontal frame, in which both the upstream side window glass and the downstream side window glass are installed in a gentle inclination, the present invention is applied to both the intermediate horizontal frame and the lower horizontal frame. The configuration may be adopted. Of course, even when the window glass is installed in a steep inclination with respect to the window frame, the configuration of the present invention can be adopted in the middle horizontal frame or the lower horizontal frame of the window frame.

In addition, the protruding frame portion is provided with a horizontal frame provided with a drainage path that penetrates the protruding frame portion in the downstream direction from the upstream side surface thereof in a horizontal direction or in a downward gradient, so that the upstream side of the horizontal frame when the rain or the like occurs. Rainwater flowing down on the upper surface of the side window glass flows into the drainage channel of the protruding frame portion of the horizontal frame, and is discharged from there onto the downstream side window glass of the horizontal frame or outside the skylight as it is. . Therefore, rainwater does not collect at the step between the horizontal frame and the lower end of the upstream window glass.

As described above, since the skylight can effectively drain the rainwater and the like to the downstream side by utilizing the horizontal frame itself, as in the conventional case, the window glass to be installed in a steep slope and the window glass Since it is not necessary to fill the step with the horizontal frame located on the downstream end side of the caulking material with the caulking material, the amount of caulking material used can be kept to a minimum and the cost of skylight construction can be reduced and the function as a skylight. Also, it does not spoil the appearance.
