[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a part for attaching a lifting and lowering device of a lift-up curtain to a lower surface of a head rail.

[0002]

2. Description of the Related Art A lifting curtain in which the front-rear width of an elevating device is larger than the front-rear width of a head rail is disclosed in Japanese Unexamined Utility Model Publication No. 62-32.
No. 194. This known device did not allow the screen to be moved from the front to the back of the headrail to change the mutual position of the screen and the lifting device. Therefore, when reversing the mutual position of the lifting device and the screen, the entire lifting curtain had to be inverted by 180 degrees, so that the position of the operation cord hanging from one end of the head rail was inevitably also on the opposite side. I had to move.

[0003]

When the positional relationship between the screen of the hoisting curtain and the elevating device is reversed, there have been many requests by users not to want to change the position of the end where the operation code hangs. The present invention has been made to meet this demand, and its purpose is to:
Leave the operation code position of the lift-up curtain as it is, and move the screen from the front side of the head rail to the rear side.
Alternatively, the position of the lifting device with respect to the screen can be changed by reversing the reverse.

[0004]

In order to achieve the above object, the present invention employs a driving unit case fixed to a head rail of a raising and lowering device of a lift-up curtain and a fixing plate of a winding pulley case. It is provided on both sides with respect to the rotation axis of the pulley.

[0005]

[Function] When the screen is lowered to the front of the head rail, a set screw is inserted into the front fixing plate of the drive unit case and each winding pulley case and screwed into the tightening plate in the head rail. Secure to the rail. To change the screen to the rear surface of the head rail, remove the set screw, move the drive unit case and each take-up pulley case slightly to the rear, align the rear fixing plate with the tightening plate in the head rail, and set the set screw again. Screw through the rear plate and into the clamping plate. As described above, when the screen is changed from the front surface to the rear surface of the head rail, the lifting / lowering device slightly moves forward in parallel, but the hanging position of the operation cord does not change at all.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a lift-up curtain according to the present invention. As shown in FIG. 1, a drive unit case 11 and a plurality of take-up pulley cases 12 are fixed to a head rail 10 of a lift-up curtain, respectively.
Secure with 13 and 14 and set screw 15. Fixing plate 13
The drive unit case 11 and the fixed plate 14 are integrally formed with the take-up pulley case 12, respectively. In the drive unit case 11, a code pulley for hanging the operation code 17 and
A planetary gear mechanism and a brake mechanism are provided to reduce the rotation of the cord pulley. The brake mechanism transmits the rotation of the output shaft of the planetary gear mechanism to the rotation shaft 19 of the take-up pulley 18, but prevents the rotation from the rotation shaft 19. To block. Winding pulley case
Rotating shaft 19 directly connected to the output shaft of the brake mechanism in 12
And the take-up pulley 18 is fixed to the rotation shaft so as to rotate integrally. Take-up tape 20 on take-up pulley 18
And the other end of the winding tape 20 is fixed to the lower end of the screen.

As shown in FIG. 2 and FIG.
When the upper edge of the head rail 10 is attached to the adhesive tape 22 on the front face of the head rail 10, the set screw 15 is inserted into the set screw hole of the fixed plate 13a, 14a on the front side of the drive unit case 11 and the take-up pulley case 12, and the head rail 10 Each fastening plate
16, the opening bottom plate of the head rail 10 is held between the drive unit case 11 and the take-up pulley case 12 and the tightening plate 16 so that the drive unit case 11 and the take-up pulley case 12
Is fixed to the head rail 10.

As shown in FIG. 2, the drive unit case 11
Projections 23a and 23b for screwing a piece 25 to be hooked on the opening bottom plate of the head rail 10 are provided on the front end and the rear side symmetrically with respect to a vertical plane including the axis of the rotating shaft 19 at the outer end of the front rail. The piece 25 is attached to the projection 23a with a set screw 24. The lower end of the winding tape 20 pulled out from each winding pulley case 12 is fixed to the screen 21. When one of the operation codes is pulled, the take-up tape 20 is taken up and the screen
21 is lifted up, and when the other is pulled, the take-up tape 20 is returned and the screen 21 is lowered.

As shown in FIG. 4 and FIG.
Adhesive tape 22 with the upper edge provided on the rear side of the head rail 10.
When the screen is turned upside down, all the parts below the head rail 10 together with the set screw 15 are removed. Then, the set screw 24 is removed and the piece 25 is replaced with the projection 23b. Then, drive unit case 11 and take-up pulley case 12
To the front side, align the rear fixing plates 13b, 14b with the position of the tightening plate 16, and again pass the set screw 15 through the set screw through hole of the rear fixing plate 13b, 14b and screw it into the tightening plate 16. , Drive unit case 11 and take-up pulley case
12 is fixed to the head rail 10. In this case, the side where the operation code is located does not change at all.

[0010]

[Effect of the Invention] As described above, in the conventional apparatus, in order to reverse the mutual position of the screen and the lifting / lowering apparatus, all the lifting curtains had to be reversed.
Although the side where the operation code is located is always inverted, the device of the present invention has an excellent effect that the mutual position of the screen and the lifting / lowering device can be inverted without changing the side where the operation code is located.
