Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention relates to a blind opening/closing device that opens and closes blinds attached to sliding windows, casement windows, double-sided windows, etc. by driving a motor.

(Prior art) As a conventional blind opening/closing device, for example,
As shown in Publication No. 60-31499, a blind A installed on the indoor side of a window is opened and closed by a motor driven by the starting force of a solar cell B installed on the outer surface of the upper part of the window frame. There is a known method in which the process is carried out using

(Problems to be solved by the invention) In conventional blind opening/closing devices, the solar cells that drive the motor are exposed outdoors, so the light-receiving surface of the solar cells is exposed to the wind and rain, causing dust, etc. It was necessary to clean the light-receiving surface of the solar cell, as the starting force was reduced due to the adhesion of light. This cleaning was time-consuming as it had to be done with care so as not to damage the solar cells.

Therefore, the purpose of this invention is to solve the conventional problems and provide a blind opening/closing device that does not require cleaning of the solar cell that is the driving source of the motor, and that has a good appearance.

(Means for Solving the Problems) In order to solve the problems of the conventional method, this invention provides a blind opening/closing device that is opened and closed using a motor 10 operated by solar cells 7, 7a, and 7b. The solar cells 7, 7a, 7b,
Upper support parts 18, 18 of window glasses 4, 4a, 4b
It is installed on the indoor side near window glasses 4, 4a and 4b in a position that receives solar radiation from the outdoor side and is hidden from the indoor side by a rolled-up blind c.

(Example) An example of this invention will be described below based on the drawings.

The embodiment shown in FIGS. 1 to 3 is applied to a sliding door with double-sliding windows, and A is a sliding door that has a rectangular shape with an upper stile 1, a lower stile 2, and left and right vertical stile 3, 3. The window glass 4 on the outdoor side and the window glass 5 on the indoor side are built in a frame 6 that is framed by a frame 6, and a space B is formed between the window glasses 4 and 5.
A blind C is placed in this space B as shown in FIG.
is provided. The blind C is constructed by connecting a large number of blades 13 and a bottom rail 15 with a string 14, and the strings 14 are connected to a case 17 fixed inside the upper stile 1 with a bracket 16.
It is attached to pulleys 12, 12 which are fitted onto the shaft 11 of a motor 10 provided in the motor 10 so as to be able to be wound up and unwound freely. In addition, a motor 10 is mounted on the indoor side of the window glass 4 on the outdoor side of the sliding door A near the upper support portion 18 thereof.
A solar cell 7 that serves as a driving source is attached and provided. And the solar cell 7 and the motor 10 are the second
As shown in the figure, the blinds are connected by a lead wire 8 placed inside the vertical stile 3, and the electricity generated by the solar cell 7 is charged through the lead wire 8 to a rechargeable battery 9 installed inside the upper stile 1. The motor 10 is operated by operating a switch when winding or rewinding of the winding is required.
Note that if the starting force of the solar cell 7 is sufficient for winding up and rewinding the blind C, the rechargeable battery may not be provided.

FIG. 3 shows the rolled up blind C, which is attached above the bottom rail 15 of the rolled up blind C on the indoor side near the upper support part 18 of the window glass 4 on the outdoor side. , any location on the indoor side of the window glass on the outdoor side can be used as long as it is a part that receives sunlight from the outside and is hidden from the outside by the rolled-up blind C, and it can be placed anywhere on the indoor side of the window glass 4 without obstructing the view of the window glass 4. Batteries can be installed. Since the solar cells are attached and installed on the indoor side of the outdoor window glass 4, the light-receiving surface of the solar cells does not become dirty, and simply cleaning the window glass 4 reduces the activation force of the solar cells. It can be used without any problems.

Figures 4 and 5 are applied to a window that has not been fitted.
The solar cell 7a is attached and installed on the indoor side near the support part 18a above a, and FIG. This is an example in which it is provided near the upper support portion 18b of the glass 4b.

As explained above, this invention is suitable as a blind opening/closing device for sliding windows and blind windows, but it can also be applied as a blind opening/closing device for casement windows, revolving windows, etc., as long as they have window glass that receives solar radiation. It is something that can be done. In addition to the glass plate, the window glass on which the solar cell is attached may be a transparent synthetic resin plate such as an alkaline resin.

(Effects of the invention) This invention has the above-mentioned configuration, and the solar cell that drives the motor for opening and closing the blind is attached to the indoor side near the upper support part of the window glass that receives solar radiation, so that the solar cell The light-receiving surface of the solar cell does not get dirty and there is no need to clean it, and the solar cell can be used without reducing its electromotive force just by cleaning the window glass.It is extremely easy to maintain and manage the solar cell, and it is easy to install the solar cell. It does not require any special configuration, and even when the blind is rolled up, the solar cells are not visible from the inside, so it looks good and has excellent effects such as not obstructing daylight. It is.
