DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skylight device having a light-shielding door which can be easily opened and closed.

[0002]

2. Description of the Related Art In recent years, houses, theaters, rehearsals, and the like, in which a skylight device is provided on a roof to perform daylighting and ventilation, have increased. However, when the skylight device is installed, there is a concern that the inside of the room is peeped at night, and in a theater or the like, it is necessary to block light during the daytime and darken the inside of the hall.

For this reason, a conventional skylight device is provided with a slide-type light-shielding plate or a roll-out light-shielding sheet that can be fed out so that light can be blocked when necessary. There are many.

[0004]

However, the above-mentioned skylight device uses a long operating rod to hook the hook at the tip thereof on a light shielding plate or a light shielding sheet, and slides the light shielding plate along the guide grooves on both sides. Or, since the light-shielding sheet is fed out of the roll to perform the opening and closing operation, the opening and closing operation is considerably troublesome. Moreover, when the light shielding plate is large,
Since a considerable force is required for opening and closing operations, there is a problem that it is difficult for women to open and close. Further, if the direction of the light shielding plate or the like becomes oblique during the opening / closing operation, both ends thereof are caught in the guide groove and cannot move smoothly, so that there is a problem that the opening / closing operation becomes difficult.

[0005] The present invention has been made in view of the above problems, and an object of the present invention is to provide a skylight device having a light-shielding door that can be easily opened and closed.

[0006]

In order to achieve the above object, a skylight apparatus according to the present invention has a skylight mounted on an upper end of a skylight mounting port, and a light-shielding door is pivotally mounted to open freely inside the skylight mounting port. Then, a fixed pulley was provided above the light-shielding door, a wire for opening and closing the light-shielding door was wrapped around the constant pulley, one end of the wire was temporarily fixed to an accessible location, and the other end was fixed to the light-shielding door. Or with a skylight attached to the upper end of the skylight mounting hole, and two light-shielding doors pivoted downward and open inside the skylight mounting hole, and a fixed pulley above the light-shielding door. At the same time, a moving pulley is attached to each light-shielding door, a wire that opens and closes the light-shielding door is bridged between these pulleys, and one end of the wire is temporarily fixed to a location where it can be reached.

[0007]

According to the skylight device of the present invention, when the temporary stop at one end of the wire for opening and closing the light-shielding door is released and the wire is loosened, the light-shielding door, which has been closed by the pulling force of the wire, pivots by its own weight. Is pivoted downward around the center to open the skylight, and the skylight mounting opening is opened, so that light can be collected through the skylight. And
When one end of the wire is pulled back, the light-shielding door that has opened downward pivots upward due to the pulling force of the wire and returns to its original closed state. Is kept closed by the light blocking door, so that light from the skylight can be blocked.

As described above, in the skylight device of the present invention, since the light-shielding door is opened downward around the pivot point by its own weight, the opening and closing operation is far more in comparison with a conventional slide-type light-shielding plate or the like. The light-shielding door can be opened and closed simply by loosening or pulling back the wire temporarily fixed to a place where it can be reached without the need for using a long operating rod, and the opening and closing operation is extremely easy.

In particular, two light-shielding doors are pivotally attached to the inside of the skylight window so as to open downward, and fixed pulleys are disposed above the light-shielding doors, and moving pulleys are attached to the respective light-shielding doors. Is constructed so as to span the wire between the pulleys,
When the light-blocking door is double-opened, the width of the light-blocking door that hangs down from the skylight mounting opening is short (half the width when one light-blocking door is opened downward). In addition, since the pulling force of the linear body is greatly reduced by the action of the fixed pulley and the moving pulley, even a woman can easily and smoothly open and close the light shielding door.
