Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electric blind that controls the elevation and rotation of the slats of a plurality of blinds individually or all at once.

[Prior Art] Conventionally, electric blinds that control the elevation and rotation of the slats of a plurality of blinds individually or all at once usually
The signal emitted by the command means is once input to a control device installed in the head box of the parent blind, the content of the signal is judged, and based on the content, the parent blind or the child blind electrically connected to the parent blind configured to transmit a signal to. An example of such a conventional structure is shown in FIG.

What is shown in Figure 4 is three electric blinds la and lb.
, lc. Of these blinds, 1a
is the parent blind, and the control device 2 is installed inside the parent blind.
Built-in.

1b and 1c are child blinds, and the child blinds do not have a built-in control device. The signal is received by the simultaneous command means, ie, the multi-controller 3, which controls these blinds all at once, and the individual command means, ie, Jingleco, which controls each blind individually, and this signal is sent to the control device 2 provided in the head box of the parent blind 1a. Once input, the content of the signal is determined, and based on the content, the parent blind Fl a itself is operated, or it is transmitted to the child blinds 1b to 1c electrically connected to the parent blind, and the child blinds 1b and 1c are /or 1
c is operated. In addition, when operating the blinds la, lb, and lc individually, the single controllers 4a and 4
Each blind is controlled by b and 4c.

In such conventional electric blinds, each blind must be manufactured in advance by dividing it into a parent blind and a child blind. In addition, the head box has a built-in control device, so it has become larger, and it is also possible to store the head box in blinds with narrow slats, which have recently become widely used, or in curtain boxes. This required a large curtain box, which was an obstacle when installing electric blinds in houses. Furthermore, since the signal input terminal and output terminal of each blind are arranged separately on the left and right ends of the head box, the signal output from the parent blind is transmitted in series to the child blinds connected to the parent blind. , Due to wiring constraints, it is not possible to freely determine the position of the parent blind.

[Problems to be Solved by the Invention] The present invention solves the above-mentioned inconveniences of conventional electric blinds, eliminates the need to separately produce parent blinds and child blinds, miniaturizes the head box, and improves design. It is an object of the present invention to provide an electric blind which has excellent performance and can be wired conveniently.

[Means for Solving the Problems] As a means for solving the above-mentioned problems, the present invention provides an electric blind that controls the elevation and rotation of the slats of a plurality of blinds individually or all at once. A control device for controlling is provided independently from the head box of each blind, and an input terminal for inputting a signal from a command means for instructing each blind to raise, lower, or rotate the slats to the control device, and An electric blind is provided, characterized in that output terminals for outputting signals to a blind control device are provided in parallel.

Preferably said control device is provided with at least three output terminals. In addition to the input/output terminals for individual or simultaneous control, it is preferable that each blind control device is provided with an individual operation terminal for manually inputting the signal 5 from the command means for operating the blinds individually.

[Operation] In the electric blind of the present invention, there is no need to set the parent blind and child blind separately, and each blind is provided with a control device separate from the blind body, and a control device connected to a command means (wired type or wireless type) is installed. Signals input to the control device of the stand via the dual input/output terminal are input to the control circuit of the control device and are separated from other input/output terminals provided in parallel with the input/output terminal. It is output as is to the blind control device. In this way, the control device for each blind determines whether the signal inputted by its control circuit is a command for that blind, and if so, operates the blind main body in accordance with the contents of the command. Furthermore, by providing three or more input/output terminals in the control device, it is not necessary to connect the blinds in series, and wiring between the blinds can be freely performed.

6- If the single operation switch is connected to the single operation signal input terminal of the control device, it can operate only the blinds connected to that control device, and by connecting it to any of the input/output terminals, it can be used as a simultaneous operation switch. All the blinds connected to the other input/output terminals of the control device can be operated in the same manner at the same time.

[Example code] Hereinafter, the present invention will be described in detail with reference to the drawings.
