Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to the opening/closing structure of lighting windows, and relates to so-called skylights, etc., which are installed on the roof or outer wall of a building such as a house for the purpose of letting light into the room. This relates to a structure for opening and closing a lighting window.

[Conventional technology]

Daylight windows such as skylights are used in various buildings as they allow outdoor sunlight to enter indoors, save energy from electric lighting, etc., and provide a natural and comfortable lighting environment that cannot be achieved with artificial lighting. has been adopted.

There are two types of daylighting windows: those with a structure in which glass, etc. is fitted onto the opening surface and permanently fixed, and those with a structure that has a door that can be opened and closed on the opening surface so that the daylighting window can be opened and closed as needed. be. In the case of a lighting window that has a structure that can be opened and closed, it is very convenient to leave the opening and closing door open, as it allows ventilation or ventilation at the same time as letting in light. Such a retractable daylighting window is opened during bright daytime hours to let in enough sunlight, and closed when the sun sets. This is because if you leave the lighting window open at night, it is not desirable for crime prevention, and it also causes problems such as cold air, night dew, insects, etc. to enter through the lighting window, so it is recommended that you close the lighting window at night. be.

Lighting windows are installed at high positions, like skylights installed on the roof, and it is often difficult for residents to reach out and open and close them. Some devices are equipped with an electric opening/closing mechanism, and the lighting window is opened/closed by actuating this electric opening/closing mechanism by operating a handheld opening/closing switch or the like.

[Problem to be solved by the invention]

However, in the case of the above-mentioned type of opening/closing daylighting window, it is necessary to open and close it every day and night, which is very troublesome.
In particular, if people forget to close the lighting windows and leave them open even at night, this can cause problems such as the cold air entering the room. As mentioned above, normal lighting windows are located high up and are difficult for residents to see, so even if the lighting windows are left open, they often go unnoticed, resulting in the problem of people frequently forgetting to close them. .

Therefore, the problem of this invention is to provide a lighting window that can be opened and closed.
To provide an opening/closing structure capable of automatically closing an opening/closing door when it gets dark outside.

[Means to solve the problem]

The present invention, which solves the above problems, is a daylighting window equipped with an electric opening/closing mechanism that mechanically opens and closes the daylighting window, and which includes a light sensor that detects outdoor brightness and a detection signal from the light sensor. A control means for controlling the operation of the electric opening/closing mechanism is provided.

[For production]

If you detect the outdoor brightness with a light sensor,
When the light sensor detects that the outdoor brightness has fallen below a certain level of illuminance, the control means is activated and the electric opening/closing mechanism is activated to close the lighting window.

〔Example〕

Next, the present invention will be explained in detail below with reference to the drawings showing examples.

Figure 1 shows the overall configuration of the opening/closing structure.
The basic structure is similar to that of a normal daylighting window, and includes an opening frame 10 formed through the roof surface of a building, and an opening/closing door 11 that closes this opening frame 10. , an electric opening/closing mechanism 12 for operating the opening/closing door 11
In the illustrated embodiment, the opening/closing door 11 is hingedly connected to the opening frame 10 at the negative side so that it can be opened by rotating upward, but it can be opened by sliding. The present invention can be implemented with various types of opening/closing door structures employed in normal daylighting windows, such as those in which the opening/closing door 11 opens in multiple parts.

The electric opening/closing mechanism 12 can perform the opening/closing operation of the opening/closing door 11 as described above by combining a motor, an electromagnetic cylinder, a cam, a chain mechanism, and various other mechanical and electrical mechanisms. The operating mechanism can be electrically controlled, and the specific mechanism and structure are similar to those of a normal electric opening/closing daylighting window, so a detailed explanation will be omitted.

A light sensor 20 is installed facing outdoors, such as a roof or wall surface on which a lighting window 1 is installed.

The light sensor 20 is a sensor that detects a decrease in outdoor illuminance, and is capable of outputting a detection signal when the outdoor illuminance changes below a certain level. For the structure and structure, one having the above-mentioned functions can be used from among various ordinary optical sensors.

The detection signal from the light sensor 20 enters a light sensor control section 21 consisting of an appropriate electronic circuit, and is transmitted from the light sensor control section 21 to an opening/closing mechanism control section 30 that directly controls the operation of the electric opening/closing mechanism 12. The control unit 30 operates the electric opening/closing mechanism 12 to close it.

The light sensor control unit 21 is provided with an on/off switch 22 that turns on/off the operation of the light sensor 20, so that the light sensor 20 can be made not to operate when it is not necessary. The opening/closing mechanism control section 30 includes an opening/closing operation switch 31
is provided, and by operating this opening/closing operation switch 31, the electric opening/closing mechanism 12 can be operated arbitrarily to open/close the lighting window 1. Therefore, when closing the daylight window 1 at sunset, the electric opening/closing mechanism 12 is activated by the command from the light sensor 20.
When opening the lighting window 1 in the morning or during the day, the electric opening/closing mechanism 12 may be activated by operating the opening/closing operation switch 31.

Next, Fig. 2 specifically explains the operating mechanism of the light sensor 20 using a graph, and shows that the outdoor illuminance changes over time (shown in the central graph curve). At the same time, the illuminance suddenly decreased, and as the night passed,
The illuminance increases again as the sun rises. This illuminance is a preset reference level. When the temperature is below, the light sensor 20 outputs a detection signal, the light sensor control section 21 outputs a closing operation signal (pulse signal shown in the upper part of the figure) to the opening/closing mechanism control section 30, and the opening/closing mechanism control section 30
operates the electric opening/closing mechanism 12 to close the opening/closing door 11. A reference level L of illuminance at which the light sensor 20 operates;
It is preferable that it can be set arbitrarily, and usually it is 5 to 5.
It should be possible to set it within a range of about 300Lx.

Next, FIG. 3 shows a flowchart of the operation process of the light sensor 20. In step (2), when a signal corresponding to the illuminance is input, in step (2), the illuminance decreases in accordance with the change in illuminance. Determine whether it is a change from day to night, where the illuminance increases, from night to morning, or from morning to day. If it is a change from day to night, the process moves to the next step (2), where it is detected that it is sunset, and if the change is other than that, the process returns to the input waiting state of step (2). When step ■ detects that it is sunset, step ■ opens and closes door 1.
1 is in the open state. If the opening/closing door 11 is in the open state, the process moves to the next step (2), outputs a closing operation signal, and then returns to the input waiting state of step (2). If the opening/closing door 11 is in the closed state, the process returns to the input waiting state of step (2) without proceeding to step (2).

If the light sensor 20 is activated according to the flowchart above, sunset will be reliably detected and the daylight window 1 will be activated.
In addition, since the closing operation signal is not output when the lighting window 1 is already closed, the opening/closing operation by the opening/closing operation switch 31 can also be used. The control functions explained in this flowchart are as follows:
This is realized by an appropriate electronic circuit incorporated in the light sensor 20, the light sensor control section 21, or the like.

In the embodiment described above, the lighting window 1 is controlled by the light sensor 20.
The operation is controlled only during the closing operation at sunset, but the light sensor 20 detects the change in illuminance when the sun rises, and the electric opening/closing mechanism 12 is operated based on the detection signal to let in the light. If the window 1 is left open, it is possible to automatically open and close the lighting window 1.

The opening/closing structure of the daylighting window according to the present invention can be applied to the daylighting window of any structure provided on the roof or outer wall surface of various buildings, in addition to the above-mentioned skylights for general residences.

[Effects of the Invention] According to the opening/closing structure of the lighting window according to the present invention described above, by detecting with the light sensor that the outdoor brightness has become below a certain level at sunset, The electric opening/closing mechanism can be activated to automatically close the daylighting window, eliminating the need for the extremely troublesome task of closing the daylighting window every day at sunset. No more forgetting to close it. therefore,
Problems such as security problems and cold air infiltration are completely resolved, making it possible to use retractable lighting windows with peace of mind, and making a major contribution to the spread of retractable lighting windows in general homes. etc., are extremely practical.
