Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a retractable skylight.

[Prior Art] For example, skylights have been installed on the roofs of buildings in order to bring in light indoors, but in such skylights, the difference in temperature between indoors and outdoors causes the difference between the outside air and the outside air. Condensation tends to form on the inner surface of the dome that comes into contact with the dome, and the condensed water falls and stains the floor, furniture, etc., which is disadvantageous. Therefore, when providing a skylight, it is necessary to provide some kind of means for treating the condensed water.

In this case, it is conceivable to install a gutter-like part and a discharge hole in the fixed frame of the skylight to catch the condensed water and discharge it outdoors, but by installing the gutter-like part, the seal between the fixed frame and the opening/closing frame can be sealed. Since there is a space below the sealing surface, rainwater may enter the room from the sealing surface when the wind and rain are strong. Although a sealing member is usually provided on the sealing surface to prevent rainwater from entering, the sealing member is easily aged when exposed to sunlight and the outside air, so even if a sealing member is provided, rainwater will not enter indoors. It is difficult to completely prevent the infiltration of

[Problem to be solved by the invention] The problem to be solved by the invention is to provide a retractable skylight that drains condensed water from the skylight outdoors and completely prevents rainwater from entering the room. .

[Means for Solving the Problems] In order to solve the above problems, the present invention includes a fixed frame for fixing to an opening in a building, and an opening/closing frame pivotally connected to the fixed frame so as to be freely openable and closable. In the retractable skylight, the opening and closing frame is equipped with a lighting dome and a stay that biases the opening and closing frame in the opening and closing direction. A gutter-shaped part that catches the condensed water falling from the lighting dome, a discharge hole opened in the water return wall of the gutter-shaped part to drain the condensed water outdoors, and a drainage wall that hangs down from the outdoor end are formed. A waterproof wall that blocks rainwater from entering the room is vertically installed at the outdoor end of the opening/closing frame, which is on substantially the same vertical plane as the draining wall, with a gap between it and the fixed frame that allows condensed water to drain outdoors. It is characterized by what it did.

[Function] The condensed water on the inner surface of the daylighting dome flows into the gutter-like part along the slope of the dome, and is discharged outdoors through the discharge hole through the gap between the fixed frame and the waterproof wall, so that the condensed water is kept indoors. It will not fall and stain the floor or furniture.

In addition, a waterproof wall hanging from the outdoor end of the opening/closing frame
Since it blocks rainwater from blowing into the sealing surfaces, even in strong winds and rain, rainwater can be completely prevented from entering the room through the sealing surfaces of both frames.

[Effects of the invention] The opening/closing skylight of this invention catches the condensed water on the inner surface of the lighting dome in the gutter-like part and discharges it to the outside through the discharge hole, which prevents condensed water from falling into the room and staining the floor and furniture. be able to.

In addition, a waterproof wall hanging from the outdoor end of the opening/closing frame
Because it blocks rainwater from blowing into the sealing surfaces of both frames,
Rainwater can be completely prevented from entering the room through the sealing surface.

Furthermore, by locating the waterproof wall and the drainage wall on substantially the same vertical plane, it is possible to prevent the aesthetic appearance from being degraded due to misalignment of both walls.

[Example] Hereinafter, an example of the present invention will be described in detail based on the drawings.

and a rectangular opening/closing frame 5 pivotally connected to the fixed frame 4 with a hinge 7 so as to be freely openable/closable, and a daylighting dome 8 made of a translucent material such as synthetic resin is fixed to the opening/closing frame 5 with bolts 9. This dome 8 has a double structure, consisting of an inner dome 8a having an inclined surface 10 for guiding condensed water adhering to the inner surface to fall to the outer periphery, and an outer dome 8b attached to the outside of the inner dome 8a. A sealing member 12 made of rubber or the like is interposed between the vertical water return wall 11 provided on the fixed frame 4 and the opening/closing frame 5.
The skylight 3 is configured to come into contact with the skylight 3 in a watertight manner when it is closed.

In addition, the water return wall 11 of the fixed frame 4 and the opening/closing frame 5
As a means for opening the skylight, a stay 13 that biases the opening/closing frame 5 in the opening direction with the force of a spring is installed on the inner surface of the skylight between the inner wall 5a and an arm for opening/closing operation fixed to the opening/closing frame 5. 14 is provided with a locking pawl 16 that locks into the gutter-like portion 15 on the fixed frame 4 to hold the opening/closing frame 5 in the closed position, and a release lever 17 for releasing the locking of the locking pawl 16. Furthermore, a latch 18 is provided for pulling down the opening/closing frame 5 in the open position to close it.

At the inner end of the fixed frame 4, the main body wall 4a is extended so as to protrude inward from the wall 1, so that the wide gutter-like shape is formed to catch the condensed water falling from the daylighting dome 8. A drain hole 1 for condensed water accumulated in the gutter-like portion 15 is provided around the gutter-like portion 15.
9 is bored at the lower end of the water return wall 11. It is desirable that the discharge holes 19 be as small and as few as possible within the range necessary for discharging condensed water in consideration of rain closure.
a may be formed horizontally as shown, but
It may be tilted slightly so that the outdoor side is lower.
This makes it possible to further improve the ability to drain the condensed water.

The stay 13 is housed in the internal space of the gutter-like part 15, and the stay 13 is configured so that when looking up at the skylight from below, the stay 13 is in the shadow of the gutter-like part 15 and cannot be seen directly. There is.

Furthermore, in order to improve rain protection at the skylight 3, a downwardly extending draining wall 20 is formed at the outdoor end of the fixed frame 4, and a caulking material 21 is filled between the draining wall 20 and the wall 1. On the other hand, at the outdoor end of the opening/closing frame 5, a waterproof wall 22 is vertically provided to face the draining wall 20 with a small distance therebetween.

The fixed frame 4 and the opening/closing frame 5 have the width of the water return wall 11 and the water draining wall 20 in the fixed frame 4.
_W1 is formed to be approximately equal to the width _W2 of the inner wall 5a of the opening/closing frame 5 and the waterproof wall 22, and the inner wall 5
