Abstract

PURPOSE:To improve wind resistance and earthquake resistance by providing a cover body having an opening part approximately in the shape of a semicircle, a rotatable round type frame having a glass surface and an opening part, and a window frame body to which a driving part is attached. CONSTITUTION:A cover body 1 having a semicircular opening part and a round frame 2 are held rotatably around a central part, and secured to a window frame body 3 in a manner to cover an opening part 5 of the body 3 therewith. The frame 2 having a semicircular glass surface 6 and an opening part 7 is fixed to the body 3 in a manner to make contact with a rotary body 9 rotated with the aid of an electric driving part 8 disposed to the body 3. In case of a natural lighting window being in a state that the window is completely closed, the glass surface 6 is fixed in a position where the glass surface coincides with an opening part 4. When the window is opened, a rotary body 9 is rotated to gradually bring the opening part 7 into an opening space having a desired area coinciding with that of the opening part 4. This constitution facilitates execution of opening and closing with the aid of a small driving body 8 and enables improvement of wind resistance and earthquake resistance.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting window. More specifically, the present invention relates to a new daylighting window having an opening / closing mechanism with a simple structure.

[0002]

2. Description of the Related Art Conventionally, a roof portion of a house or the like has been provided with a daylighting window having various structures and designs, and in recent years, an electric daylighting window for electrically controlling the opening and closing of the window has been started to be used. . Such a daylighting window is, for example, as in the case of the vertically opening / closing type daylighting window (a) shown in FIG. To open and close the window frame (d) up or down, or slide the window frame (d) left and right as in the case of the slide opening / closing type lighting window (e) illustrated in FIG. 4 (b). I try to open and close it.

[0003]

However, in the conventional daylighting window, for example, in the case of the vertical opening / closing type daylighting window (a) shown in FIG. 4 (a), the maximum opening angle of the window frame (d) is There are problems that it is as small as about 20 ° and that opening and closing of it requires a reinforcing member such as a gas spring.

Further, in the case of the slide opening / closing type lighting window (e) illustrated in FIG. 4 (b), the sliding operation of the window frame (d) is not only a simple horizontal movement but also the start of the sliding operation. Occasionally, the window frame (d) is once lifted upward, which complicates the structure of the drive unit. Furthermore, these conventional daylighting windows (a) and (e) are kept in an extremely unstable state by opening the window frame (d) upwards or laterally when they are opened, so that they are windproof and earthquake resistant. It was not preferable from the point of view.

The present invention has been made in view of the above circumstances, solves the drawbacks of the conventional daylighting windows, has a small structure with a simple structure, and can be easily opened and closed. Moreover, it aims to provide a new daylighting window with excellent wind resistance and earthquake resistance.

[0006]

In order to solve the above problems, the present invention provides a cover body having a substantially semicircular or hemispherical opening portion, a glass surface and an opening portion each having a substantially semicircular shape or There is provided a daylighting window characterized by comprising a rotatable round frame having a hemispherical shape and a window frame body to which a drive unit for rotating the round frame is attached.

[0007]

The lighting window of the present invention has a glass surface and an opening,
The windows are opened and closed by rotating a round frame having a semicircular or hemispherical shape, respectively. Therefore, the drive unit that rotates the round frame can be configured with a simple structure. In addition, since the driving force is small, the driving unit itself can be downsized.

Further, the daylighting window of the present invention is stable in the installation condition even when it is opened / closed, and therefore wind resistance,
Seismic resistance is also very good.

EXAMPLES Examples will be shown below with reference to the accompanying drawings.
The present invention will be described in more detail. FIG. 1 is an exploded perspective view showing an embodiment of a daylighting window of the present invention. For example, as shown in FIG. 1, the lighting window of the present invention is
It has a cover body (1), a round frame (2) and a window frame body (3).

The cover body (1) has a semicircular opening (4).
And has a round frame (2) rotatably held at the center and is fixed so as to cover the opening (5) of the window frame body (3). Round frame (2) has a glass surface (6)
And an opening (7) each having a semicircular shape, and are rotatably fixed to the window frame body (3) together with the cover body (1). At that time, the surrounding back surface of the round frame (2) is
An electric drive unit (8) arranged on the window frame body (3) comes into contact with a rotating body (9) that rotates.

The glass surface (6) and the opening (7) of the round frame (2) have substantially the same size and shape as the opening (4) of the cover body, and the glass surface ( The circle formed by combining 6) and the opening (7) is substantially the same as the opening (5) of the window frame body (3). Figure 2
3A and 3B are schematic plan views illustrating the opening / closing operation of the electric lighting window illustrated in FIG. 1, respectively.

For example, as shown in FIG. 2 (a),
When the lighting window is completely closed, the glass surface (6) of the round frame (2) is fixed at a position corresponding to the opening (4) of the cover body (1). On the other hand, when opening this daylighting window, the electric drive unit (8) is operated to rotate the rotating body (9) and rotate the round frame (2) in the direction of the arrow in the figure. By doing so, the opening (7) of the round frame (2) gradually coincides with the opening (4) of the cover body (1), and an opening space of a desired size is obtained.

The opening / closing of the opening (4) is
For example, a rain detection device, a room temperature sensor, or the like may be connected to the electric drive unit (8), and automatic operation may be performed by these signals. Of course, a manual system or a semi-automatic system may be used instead of the electric drive unit (8).
FIG. 3 is a perspective view showing another embodiment of the daylighting window of the present invention.

In the case of the example of FIG. 3, the cover body (1)
And the glass surface (6) is formed in a hemispherical dome shape, and is easily opened by rotating the glass surface (6) in the direction of the arrow in the figure by a drive unit (not shown) incorporated in the window frame body. You can get a space. Moreover, this electric lighting window is similar to the electric lighting window illustrated in FIG. 1, because the drive unit opens and closes the glass surface (6) by a simple rotational movement, so that the structure can be simplified and the device itself can be miniaturized. it can.

Of course, the present invention is not limited to the above examples, and it goes without saying that various aspects are possible in details.

[0016]

As described in detail above, according to the present invention, there is provided a daylighting window which has a simple structure and can be easily opened and closed by a small-sized driving portion and which is excellent in wind resistance and earthquake resistance.
