Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a string-type curtain opening / closing device for use in an arch type curtain rail that draws a curve on a vertical surface.

[0002]

2. Description of the Related Art A conventional curtain opening and closing device for pulling a string to open and close a curtain is to pass a string inside a curtain rail,
It was a method of fastening a part of the string to a string runner. The curtain was suspended from each runner projecting from the opening extending in the center of the inner bottom surface of the curtain rail in the longitudinal direction. The wheels of each runner traveled on the wheel running surface on the inner bottom surface of the curtain rail extending along both sides of the opening, and the string slid on the string running surface extending on the outer side of the wheel running surface on the inner bottom surface of the curtain rail.

[0003]

When an arch-shaped curtain rail is installed along an arched window and an arched curtain hung from the curtain rail is opened and closed by a cord, the conventional curtain opening and closing device is a cord. Since the slides on the running surface of the semicircular string on the inner bottom surface of the curtain rail, the resistance against running of the string becomes extremely large. Therefore, it is practically impossible to open and close the arched curtain of the arched curtain rail by pulling the string of the conventional curtain opening and closing device.

The present invention has been made to solve this problem, and an object of the present invention is to provide a device capable of opening and closing an arched curtain suspended from an arched curtain rail by a string. It is in.

[0005]

In order to achieve the above-mentioned object, the means adopted by the present invention is to provide a plurality of arch guides on the outside along an arch type curtain rail, and to the arch guides two guide rollers. Are attached so as to rotate independently of each other, and a string drive unit for running the string and an adjuster for tensioning the string are provided at both ends or in the vicinity of the arch type curtain rail, and the forward side of the string is used as one guide of the arch guide. This is because the return path side of the roller is along the other guide roller. The arch guide consists of a main body, a claw that is detachably fixed to the main body, a roll shaft that is fixed to the main body, and two guide rolls that are loosely fitted to the roll shaft. It is desirable to fix it to the rail in a detachable manner.

[0006]

[Operation] The string for opening and closing the arched curtain is arranged in parallel with the curtain rail and in a semicircular shape, and the outward path thereof is from the string drive unit to the peripheral surface of one guide roller of the arch guide along the arched curtain rail. Along the way to the adjuster portion, it is reversed there to become the return path side, and returns to the string drive portion along the peripheral surface of the other guide roller of the arch guide. When the string driving unit is operated by a motor or the like, the string runs parallel to the arched curtain rail. When the string hook of the string runner is extended to the upper surface of the guide roller of the arch guide and the string is attached to the string runner, the curtain is opened and closed by the running of the string. Since the string travels in contact with multiple guide rollers in a dot shape, even if the string running path has a semicircular shape, the string runs against the running of the string compared to sliding on the string running surface in the curtain rail. The resistance is greatly reduced. Therefore, the arch-shaped curtain hung by the arch-shaped curtain rail can be smoothly opened and closed by pulling the string.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The apparatus and parts of the present invention will be described based on the embodiments shown in the drawings. As shown in FIG. 1, the arch type curtain rail 10 is fixed to a window frame or a wall surface by a bracket (not shown) along an arched window. A motor set 11 as a string driving unit for running the string on one end side of the curtain rail 10 and an adjuster for tensioning the string on the other end side.
12 will be provided. The motor set 11 and the adjuster 12 are fixed to the curtain rail 10 or the window frame or wall surface. 11 arch guides in the middle of the curtain rail 10 excluding both ends
Fix 20 at equal intervals. Pass the cord 14 around the motor set 11 and the adjuster 12 through each arch guide 20. Although no runners other than the draw runner 13 are shown, a plurality of runners are movably mounted in the curtain rail, and the upper edge of the curtain is fixed to each runner. A string for opening and closing the arched curtain is stretched in a semicircular shape in parallel with the curtain rail.

As shown in FIGS. 2 and 3, the arch guide
Reference numeral 20 denotes a main body 21, a claw 22 fixed to the main body via a set screw 23, a roll shaft 28 fixed to the main body 21, and two guide rollers attached to the roll shaft so as to rotate independently. It consists of 26 and 27. The main body 21 is formed by processing a flat plate, and includes a flat plate-shaped half portion 30 that is a flat plate and a U-shaped half portion 31 that is bent in a U-shape. Both sides of the flat plate-shaped half portion 30 are cut down to form a hook 24 for hanging on one ear 17 of the upper portion of the curtain rail 10. The tip of the claw (22) is also bent in a hook shape to form a hook (25) to be hooked on the other ear (17) on the upper portion of the curtain rail (10).

Inside the U-shaped half 31 of the main body 21, two guide rolls 26 and 27 are accommodated side by side in the axial direction, and the U-shaped half 31 is formed.
The headed roll shaft 28 is passed from the outside of the. The two guide rolls 26 and 27 are loosely fitted to the roll shaft 28, and the tip of the roll shaft 28 is caulked to the U-shaped half 31. The axis of the roll shaft 28 is orthogonal to the plane including the center line of the curtain rail 10 in the longitudinal direction.

When the hook 24 of the main body 21 is hooked to one ear 17 of the curtain rail 10 and the hook 21 of the claw 22 is hooked to the other ear 17 and the set screw 23 is tightened, the main body 21 is firmly fixed to the curtain rail.
Fixed at 10. The string hook 16 of the string runner 13 extends in a crank shape to the upper surface of the guide roller 27. A part of the return path side 15 of the string along the guide roller 27 is placed along the string hook 16 and fixed to the string pulling runner 13.

When the motor of the motor set 11 shown in FIG. 1 is rotated, the forward path side 14 of the cord and the return path side 14 thereof travel in the opposite directions, respectively, to open the arched curtain. When the motor is rotated in the reverse direction, the traveling on the outward side 14 and the return side 15 of the cord will be in opposite directions,
Close the arched curtain. While the string is running, the forward side of the string 14
Both the return path side 15 and the guide rollers 26 and 27 of the arch guide 20 come into point contact with each other, whereby the guide rollers 26 and 27 rotate. The resistance against running of the string is only the rotation resistance of the guide rollers 26 and 27, and the resistance is significantly smaller than the resistance when the conventional string slides on the inner bottom surface of the curtain rail, so the string is semicircular. Even if it is stretched in a shape, traveling is smooth and the arched curtain can be opened and closed easily by a motor or a guide.

In the above-mentioned embodiment, the guide roller of the arch guide is arranged radially inward of the curtain rail, that is, at a lower position, but as shown in FIG.
It is also possible to dispose the guide rollers 26, 27 at the same position as the curtain rail 10 or at a higher position. In this case, the string
The tension position of 14, 15 and the shape of the U-shaped half portion 31 of the main body 21 change, but other things, that is, the flat plate-shaped half portion 30 of the main body, the claw 22 for fixing to the main body, the set screw for fixing the claw 23, hooks 24, 25 for holding the curtain rail, guide rollers 26, 27,
The shape of the roll shaft 28 can be the same as in the above embodiment.

[0013]

Since the device of the present invention is a system in which the guide roller of the arch guide provided along the arch type curtain rail is stretched with a cord for opening and closing the curtain, the cord can be stretched in a semicircular shape. The running resistance of the string is small, and the arched curtain can be opened and closed easily by pulling the string manually or with a motor.
