Abstract

PURPOSE:To maintain a cloth in a strained state by placing a pair of winding pipes on upper and lower parts inside a double sash and attaching upper and lower parts of a screen cloth which varies sequentially or gradually in color, pattern, etc., to the winding pipes. CONSTITUTION:A pair of winding pipes 2, 3 are placed at an upper part and a lower part inside a double sash 1, and an upper end and a lower end of a screen cloth 4 which sequentially varies in color, pattern, transparent part, etc., in a lengthwise direction are attached to the winding pipes 2, 3. One of the winding pipes 3 is connected with a motor 7 which rotates in a direction of winding or unwinding the cloth while the other winding pipe 2 is equipped with a tensile means for pulling the cloth 4 in a constant strained state. Thus the cloth 4 can be kept in a strained state without wrinkles.

Description

Detailed Description of the Invention (Industrial Field of Application) The present invention is characterized in that a pair of winding pipes are arranged above and below inside a double sash having front and rear glass plates. The upper and lower sides of a screened raw cloth that has a long length and that have different colors, patterns, patterns, transparency, etc. in the longitudinal direction sequentially or in stages are attached to the winding pipe, and the raw cloth is wound in the upper or lower direction. The desired color, pattern, pattern, and transparency can be created in the double sash by moving the raw cloth up and down by winding it around a take-up pipe, and stopping the take-up pipe when the desired part reaches the position between the glass plates. Stop the raw cloth part such as
This invention relates to a roll screen with a built-in double sash in which a desired raw cloth portion is poured into the sash.

(Prior Art) The roll screen with a built-in double sash as described above has recently been developed and has come into use.
The winding pipe is rotated manually, and it is difficult to stop the rotation of the winding pipe so that the desired part of the raw cloth is stopped at the glass plate of the satsushi, and the raw cloth parked between the glass plates may wrinkle. The appearance is unsightly, and it is relatively difficult to reveal the desired raw cloth part inside the double-sawn glass, which is its original purpose.

(Problems to be Solved by the Invention) The present invention eliminates the drawbacks of the conventional roll screen with a built-in double sash of the above type, and allows a desired raw cloth portion to be easily exposed between the glass plates of the double sash. The purpose of the present invention is to provide a roll screen with a built-in double sash, which allows the raw cloth portion to always appear between the glass without wrinkles.

(Means for Solving the Problems) As a means for solving the above-mentioned problems, the present invention provides a pair of winding pipes arranged above and below inside a double sash provided with front and rear glass plates. The upper and lower sides of the screen fabric have a length longer than the interval, and the color, pattern, pattern, degree of transparency, etc. differ sequentially or in stages in the longitudinal direction.The upper and lower sides of the screen cloth are attached to the winding pipe, The winding pipe is connected to a motor that rotates it in the cloth winding direction or the unwinding direction, and either of the winding pipes is equipped with a tensioning means that always pulls the raw cloth into a constant tension state, and To provide a roll screen with a built-in double sash, characterized in that it is provided with a motor control device that controls the rotation of the motor so as to stop a desired portion of the raw cloth at a position between the glass plates.

In a preferred embodiment of the invention, the fabric is attached to one side edge of the fabric to control a motor control device to stop a desired portion of the fabric at a position between the glass plates. A positioning mark is provided to stop the cloth at a desired position, and a reading device is provided on the side frame of the sash corresponding to the positioning mark to read the positioning mark and output a reading signal. is sent to the motor control device to stop the cloth at the desired position.

(Function) In the above-mentioned roll screen with a built-in double sash, the motor is set to operate the reading device that reads the positioning mark corresponding to the part of the raw fabric that is to be stopped between the glass of the double sash. When the raw cloth is moved in the vertical direction, the winding pipe is stopped when the desired raw cloth part comes between the glass plates of the double sash, and the desired raw cloth part appears at the glass plate. .

However, the raw cloth is always pulled up and down under a constant tension, so it does not wrinkle.

(Embodiment) The embodiment shown in the drawings will be explained below. Fig. 1 is a diagram showing an embodiment of a roll screen with a built-in double sash according to the present invention, and 1 in the figure shows a roll screen equipped with front and rear glass plates. Double sash, 2 and 3 are a pair of winding pipes arranged above and below inside the double sash, 4 is the above winding pipe 2
．． This refers to a screen cloth that has a length longer than the vertical interval of 3 and that has colors, patterns, patterns, transparency, etc. that vary sequentially or in stages in the longitudinal direction.

In the embodiment shown in FIG. 1, the raw cloth 4 has an opaque section 4a, a translucent section 4b, and a transparent section 4c.

In order to hold this raw cloth in the center position of the front and back glass plates of the double sash, guide rolls 5 and 6 are placed above and below within the frame of the sash.
are arranged so that even if the winding diameter of the winding pipe changes as the raw cloth is wound up on the winding pipe, the raw cloth is always held at the center position between the front and rear glass plates.

On one of the winding pipes (in the example shown, winding pipe 3),
A motor 7 is provided to rotate this in the raw cloth winding direction or unwinding direction, and this is driven by a drive gear 8 as shown in FIG.
It is connected to the winding vibro via.

Further, tensioning means for always pulling the raw cloth under constant tension is attached to one of the winding pipes. In the example shown, this tensioning means consists of a coil spring 9 mounted in the winding pipe 2.

In the screen with a built-in double sash, the rotation of the motor 7 is controlled by the motor control device to move the cloth up and down, and when the desired portion of the cloth comes between the glasses of the double sash, By stopping the motor, a desired raw cloth portion can be exposed within the double sash.

Furthermore, in order to automatically reveal the desired raw cloth part,
A positioning mark for stopping the raw cloth at a desired position is provided on one side edge of the raw cloth.

In the illustrated embodiment, this mark consists of the sensor patterns loa, 10b, and 10c shown in FIG. provided.

In the illustrated example, sensor patterns 10a, 10b, 1
0c is formed as a sheet having a pattern as shown in the figure, and this is attached to the back side of a transparent film sheet attached to the edge of raw cloth.

Further, the reading device 11 is formed as a photointerrupter that reads the form of this sensor pattern and issues a reading signal.

The reading signal output from this reading device is sent to the motor control device to stop the motor.

Stop the raw cloth at the desired position.

The double sash built-in roll screen described above can control raw cloth either manually or automatically. A diagram of this operating system is shown in FIG. In manual operation, the reading device is configured so that a signal is emitted when the fabric reaches the top or bottom position, and the fabric can be freely moved upwards or downwards outside of the above positions. It is a device.

(Effects of the Invention) In the roll screen with a built-in double sash of the present invention, by moving the roll screen cloth built into the double sash up and down, colors can be changed sequentially or in stages.
The desired part of the pattern, pattern, or convergence of the screen raw cloth parts with different transparency can be made to appear on the glass of the double sash, and the raw cloth can be stretched under tension to avoid wrinkles. Can hold cloth.

The operation of this raw cloth can be controlled manually or automatically from outside the double satsushi.

In the case of automatic operation, it is also possible to specify a desired cloth portion and stop the cloth at that predetermined position.
