Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a shutter with a screen installed in an opening of a building or a shower window.

(Prior art) The applicant filed a utility application filed in 1983 before filing the present application.
In No. 48753 (Utility Model Application No. 58-151293), advertisements or decorative photographs or paintings are placed near the front or back of a shutter that can be opened and closed at an opening or a show window of a building, etc. We have developed a shutter equipped with a printed screen, which is characterized by having screens printed with characters, etc. printed on them arranged side by side, and making the screens freely expandable when the shutter is closed.

This shutter is called a screen-equipped shutter, in which the lower end of the shutter and the lower end of the screen are mechanically connected.
There are two types of screens: one in which the screen is extended in conjunction with the shutter by a drive device for the shutter, and the other in which the screen has a drive device separate from the shutter and the screen is extended arbitrarily independently of opening and closing of the shutter.

(Problem to be solved by the invention) In such a shutter equipped with a screen, it is necessary to prevent the screen from being damaged due to maintenance inspections or late-night mischief, etc., so it is required that the shutter and the screen can be driven independently. .

However, as mentioned above, such screen-equipped shutters are usually installed in the opening of a building and the screen is placed facing outdoors, but if the screen is closed, In other words, when the shutter is opened or rolled up in the extended state, the screen is subjected to large pressure due to wind pressure or something leaning against it, causing so-called flutter or flapping, and the screen may come off the guide rail, causing abnormalities in opening, closing, or unfolding. In addition, there was a risk of damaging the screen.

(Means for solving the problem) In order to solve the above problem, according to this invention, a shutter that can be opened and closed provided in an opening of a building or a shower window, etc., is approached to the front or back side. In a shutter equipped with screens that can be freely expanded in parallel, a detector is installed at the lower end of the shutter to detect the presence or absence of a screen on the front or back side of the lower end, and the detector detects the presence of a screen. When the detector detects the presence of the screen, the shutter can be raised and lowered, and the screen can be raised and lowered. A shutter with a screen will be provided.

In the above configuration, the detector can wirelessly transmit a detection signal indicating the presence or absence of a screen.

In this case, there is no need to wire lead wires to the shutter that moves up and down.

In the above configuration, the shutter has an obstacle detector that detects an obstacle that interferes with the lowering of the shutter, and when the detector detects an obstacle while lowering the shutter, the shutter curtain is temporarily stopped. Then, the shutter is raised to a certain height and then lowered again, and the above operation is repeated until the obstacle is removed. When the repeated operation is repeated a predetermined number of times, the shutter is stopped and an abnormality signal is issued. Further, the obstacle detector may be connected to a wireless transmitter, and a control panel for driving the shutter may be connected to a receiver.

In this case, the shutter can be opened and closed automatically and safely at scheduled times or remotely by wire or wirelessly.

(effect) The above technical means works as follows.

Because there is always a shutter on the front or back side of the screen part when the screen is extended, that is, whether the screen is fully closed or partially closed, there is always a shutter on the back side of the screen. External forces such as wind pressure that come from the shutter side act as if they are blocked by the shutter, while those from the screen side are supported so that the screen is in close contact with the shutter, so external forces above a certain level act as if they were received by the shutter. do.

(Embodiment) An embodiment of this invention will be described with reference to the drawings. Reference numeral 1 denotes a shutter that is raised and lowered by the rotation of a shutter drum 2 by a drive device (not shown), and the lower end of the shutter 1 is Seat board 6
A detector 5 is disposed at.

3 is a screen attached to the shutter 1, and the screen 3 is connected to the screen drum 4.
is configured to be movable up and down, that is, extendable, by being rotated by a drive device (not shown), and is disposed adjacent to the shutter 1 in parallel.

The detector 5 non-contactly detects the presence of the screen 3 at the lower end of the shutter 1, and sends the detection signal to a control panel (not shown) connected to the respective drive devices of the shutter 1 and screen 3. It is something to send.

FIG. 2 is a circuit diagram of the main part when the detector 5 detects the absence of the screen 3, R is a relay activated by the detection signal of the detector 5, r1, r
2 is the contact point of relay R, M1 is the magnet for raising the shutter, M2 is the magnet for lowering the shutter,
M3 is a magnet for raising the screen, M4 is a magnet for lowering the screen, m1, m2, m3, m
4 is the contact point of each magnet M1, M2, M3, M4, SW1 is the switch for raising the shutter,
SW2 is a switch for lowering the shutter, SW3 is a switch for raising the screen, and SW4 is a switch for lowering the screen.

When this detector 5 detects that the screen 3 does not exist, switches SW1, SW2, SW
3 and SW4, the shutter 1 can be raised and lowered and the screen 3 can be raised and lowered, and when the detector 5 detects the presence of the screen 3, contacts r1 and r2 of the relay R are turned off. As a result, even if switches SW1 and SW4 are operated, shutter 1 will not rise and screen 3 will not rise.
The shutter 1 cannot be lowered and the screen 3 can be lowered only when switches SW2 and SW3 are operated.

The present invention is not limited to the above embodiments, but includes, for example, switches SW1, SW2,
The shutter 1 and screen 3 may be raised and lowered automatically in one operation by interlocking SW3 and SW4 and checking the presence or absence of the screen 3 via the detector 5. .

(Effect of the invention) As explained above, the present invention has the advantage that no matter what state the screen is in, ie, fully closed or partially closed, the screen is always in the front or back state when the screen is in the extended state. Due to the presence of the shutter, external forces above a certain level, such as wind pressure applied to the screen, are always applied to the shutter, and there is no risk that the screen will become sagging due to the wind pressure and fall out of the lifting rail. This has the effect of allowing the screen to move up and down smoothly and preventing damage to the screen.
