Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a roll blind device that covers a horizontal surface, an inclined surface, or a curved surface such as a skylight.

[Prior Art] When a roll blind is used to cover the horizontal, inclined or arched surface of a skylight, it is necessary to prevent the middle part of the screen from sagging under its own weight. For this reason, in the past, several rods were passed over the skylight to cover the screen. However, the rods placed over skylights not only look bad when the screen is open to let in light, but they also partially obstruct the daylight.

Furthermore, when opening and closing roller blinds with a motor, the screen cannot be lowered by its own weight, so it is necessary to apply tension to the screen, but there is a problem in that it is not easy to install a device that applies this tension. Ta.

[Problems to be Solved by the Present Invention] The present invention has been made to solve the above-mentioned problems, and its purpose is to provide a roll blind that does not require the screen support rod to be passed to the skylight in advance. It is about providing.

It is also an object of the present invention to provide a roll blind device that does not require tension on the screen when driven by a motor.

[Means for solving the problems] In order to achieve the above object, one feature of the present invention is as follows:
A roll blind that pulls out the screen manually or electrically and wraps the screen with a built-in spring is used, two rails are placed on both sides of the screen of the roll blind, and multiple runners are installed inside each rail so that they can run freely. are connected in a line using flexible connecting materials, and the leading runners on both sides hold the weight bars of the screen, and the other runners hold the support rods.

When opening and closing a roll blind using a motor, install a drive pulley and a tension pulley at both ends of each rail, wrap a flexible band around both, and transmit the rotation of the motor to the drive pulley.
Attach both ends of the flexible band to the leading runner. The motors in each row are started synchronously, but the motors are stopped independently for each row by limit switches installed at the start and end points of the leading runner.

[Function] A roll blind is installed on one wall of a covered surface such as a skylight, and rails are fixed to both sides of the roll blind. Each rail is equipped with runners connected in a line with a fixed length of tape, ball chain, or other flexible connecting material.
Have the first runners on both sides hold both ends of the weight bar. Support rods are passed to the runners on both sides, except for the first runner, to support the bottom of the screen. When the screen is pulled out by manually operating the weight bar, the leading runner also runs along with the weight bar. When the screen has completely covered the covered surface, the first runner reaches the end point on the rail, the runners on both sides are lined up at regular intervals on the rail, and the screen is supported on the bottom by the guide rods passed to the runners on both sides. Therefore, the shape is maintained along the coated surface. When the covered surface is open, the leading runner is at the starting point on the rail, the runners are closely aligned in a line, and there are no support rods on the covered surface, so there is no obstruction to daylight.

Separate motor-driven flexible band transmissions are installed on both rails to run the leading runners. An electric circuit starts the left and right motors of each rail synchronously, causing the leading runner to run from the starting point or ending point to unwind or wind up the screen. However, since the leading runners on both sides do not necessarily run in the same way, one The end point or start point is reached first, but since the motors on both sides are stopped independently by their respective limit switches, the leading runners on both sides are sure to stop at the start or end point.

[Example] The apparatus of the present invention will be explained based on embodiments shown in the drawings.

As shown in FIGS. 1 and 2, a roll blind 12 is installed on the wall surface 11 on one side of the skylight 10. When the roll blind 12 pulls the weight bar 13, the screen 14
is pulled out, and the pulled out screen 14 is rewound by a built-in spring. The roll blind 12 does not have a clutch, and when a pull 15 attached to a weight par 13 is hung on a hook 16 attached to the wall surface 11, the screen 14 stops covering the skylight, as shown in FIG.

Two rails 20 are provided on the wall surface 11 on both sides of the screen 14.

Runners 22 connected in a line at 1 are installed inside. The roll blind 12 and the guide roll 41 are connected to the bracket 40
The screen 14, which is pivotally supported by the roller blind and pulled out from the roll blind, passes over the runner 20 via a guide roll 41. Limit switches St and S2 are arranged at positions on the rail 20 corresponding to the starting and ending points of the leading runner 22a'.

As shown in FIG.
0, 30, rails 20, 20, etc. are fixed to runners 22, 22 excluding the leading runner on both sides, support rods 2 are attached.
3 is passed, and its support rod supports the screen 14 pulled out from the roller blind 12.

As shown in FIG. 6, a coaxially integrated input pulley 26 and a drive pulley 27 are pivotally supported on a drive pulley case 24 fixed to the end of the rail 20, and a tension pulley case 25
A tension pulley 28 is pivotally supported. A pulley 31 on the motor output shaft is connected to the input pulley 2B via a belt 32, and transmits the rotation of the motor to the input pulley 26. A cord 28 is hung between the drive pulley 27 and the tension pulley 28, and both ends of the cord 29 are fixed to the leading runner 22a. When the motor rotates in one direction, the leading runner 2
2a is from the limit switch S1 position, limit -/ )
When the motor advances to the position of the switch S2 and stops, then the motor is reversed, the leading runner 22a moves backward from the position of the limit switch S1 and stops at the position of the limit switch S2.

As shown in FIG. 7, the runner 22 installed inside the rail 20 has a flange bobbin shape, and has a support rod 23 at its axis.
Or a weight par is inserted. one flange is inside the rail 20 and the other flange is outside the rail 20;
A ball chain 21 is attached to the outer flange of the rail 20.

In the embodiment of FIGS. 8 to 1O, the rail 2o is arched, and the runners 22a, 22 protrude perpendicularly from the rail 20, as shown in FIG. Runners 22a, 22
The bottom surfaces of the runners are connected by bells 21 of a certain length, and the weight pars 13 of the roll blind 12 are passed to the leading runners 22a on both sides, and support rods 23 are passed to the other runners 22. The roll blind 12 is pivotally supported by a bracket 40, and the drawn-out screen 14 passes over each support rod 23 and reaches the weight par 13. A drive pulley case 24 and a tension pulley case 25 are attached to both ends of the rail 20.

As shown in FIG. 9, inside the drive pulley case 24,
A motor 30 with a speed reducer is installed inside, and a drive pulley 2i is fixed to the output shaft of the motor. A tension pulley 28 is pivotally supported by the tension pulley case 25, and a cord 29 is hung between the drive pulley 27 and the tension pulley 28. The cord 29 slides on the inner peripheral surface of the rail 20.

Limit switches St and S2 are installed inside the rail 20 at positions corresponding to the start and end points of the leading runner.

As shown in FIG. 10, the inside of the rail 20 is divided into two upper and lower chambers, the cord 29 is placed in the opening side chamber, and the wheels of the runner 22 are placed in the inner chamber. Both ends of the support rod 22 (or weight bar) are attached to a portion of the main body of the runner 22 that protrudes from the rail 20.

When the motor is rotated in one direction, the leading runner 22a advances from the limit switch S1 position to the limit switch S2 position in FIG. 9, so that the screen 14 is pulled out and covers the curved surface between the rails 20. First runner 22
When a presses the limit switch S2, the motor 30 stops. At this time, as shown by the chain lines in FIG. 8, the runners 22 are lined up along the rail 20 at regular intervals, and the support rods 23 passed to each runner undercover the screen 14, so that the screen 14 is arched. Maintain the expanded shape. When the motor is reversed, the leading runner 22a retreats from the limit switch S2 position, and the screen 14
is wound up by the built-in spring of the roll blind 12.

If As shown in Figure 1, a motor 30 and limit switches Sl and S2 are provided for each rail, but when the leading runner is at the starting point or ending point, the changeover switch SO
When the motor is placed in the forward or backward direction, the two motors 30, 3
0 starts at the same time. However, since the limit switch SL stops the motor rotation when the leading runner moves backwards, and the limit switch S2 stops the motor rotation when the leading runner moves forward, these operations are performed independently. Eventually, the leading runner always reaches the starting point or ending point and stops. [Effects of the Invention] As mentioned above, in the roll blind device of the present invention, the support rod that covers the middle part of the screen is pulled out together with the screen, so unlike the conventional device, it is not necessary to apply the screen to the covered surface of the skylight in advance. There is no need to keep the support rod fixed for skinning, so compared to traditional devices, the skylight during daylighting becomes unsightly due to the fixed support rod, and the daylighting is partially obstructed. It has an excellent effect of not causing any damage.

In the case of electric operation, conventional devices required a device to apply tension to the weight bar, but the device of the present invention does not require tension to be applied to the weight bar, so the entire device is simple and extremely easy to install. be. Also, there are motors on both sides.

The screen opens and closes smoothly, and the weight bar reaches its starting and ending points reliably.
