JPH0710624Y2 - Curtain rail operating device for both hand and string - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a curtain rail operating device that also serves as a guide and a string.

[Prior Art and Problems Thereof] In the pulling curtain rail, the pulling curtain rail is often opened and closed by hand like the widely used conventional curtain rail.

FIG. 3 is a partially cutaway perspective view of the conventional double-pulled curtain rail, in which the opening / closing operation cord extends from the operation section through the two-car side, through the curtain rail, and through the leading runner to the one-car side. Further, it is formed so as to pass through the curtain rail, the leading runner, and reach the two-wheel side and return to the operation section. By operating the opening / closing operation cord, the two leading runners are moved in the opening direction or the closing direction to open / close the curtain. When the above-mentioned two leading runners are provided, it is a case of double-opening, but there is also a case where one leading runner is used and single-opening is performed.

The conventional string curtain rail has a problem that it is often opened and closed by hand as described above, and the curtain or cords are often damaged at that time.

The present invention solves the above-mentioned problems, and by providing an operating device on the side of the two curtain rails, it can be used as a pulling curtain rail without being damaged as a manual curtain rail. It is an object of the present invention to provide a curtain rail operating device that can be used both as a guide and a cord for adapting to the growth of the curtain.

[Means for Solving Problems] In order to solve the above problems and to achieve the object of the invention, the guide / curtain curtain rail operating device according to the present invention is configured as follows. That is, a flexible V pulley fitted to the cord for opening and closing the curtain rail, a pressing roller that presses the cord against the V pulley, a gear formed coaxially with the V pulley, and an acceleration flat gear that meshes with the gear. A case accommodating a sprocket formed coaxially with the acceleration spur gear, a slide mounting plate for fixing the case to a fixed plate on the curtain rail two-wheel side, and a ball chain engaging with the sprocket.
It is possible to cope with the elongation of the cord by sliding the slide mounting plate downward and fixing it to the fixing plate.

[Embodiment] An embodiment of the present invention shown in the drawings will be described in detail below.
FIG. 1 is a front view showing the structure inside the case of the first embodiment, FIG.
The drawing is a right side view of the same, and FIG. 3 is a partially cutaway perspective view of a conventional string curtain rail. Here, 1 is a case, 2 is a slide mounting plate, 21 is a fixing screw, 22 is a long hole, 3 is a curtain rail two wheel, 30 is a fixing plate, 31 is a screw hole, 4 is a cord,
5 is a V pulley, 6 is a presser roller, 61 is a presser spring, 7
Is a gear, 8 is an acceleration spur gear, 9 is a sprocket, 10 is a ball chain, and 11 is a guide plate.

In this embodiment, a flexible V pulley fitted to the cord for opening and closing the curtain rail, a pressing roller for pressing the cord against the V pulley, a gear formed coaxially with the V pulley, and the gear mesh with each other. A case 1 accommodating an accelerating spur gear and a sprocket formed coaxially with the accelerating spur gear is attached to a two-wheel 3 side of a curtain rail with a slide attachment plate 2.

The slide mounting plate 2 can fix the slide of the mounting plate 2 with a fixing screw 21. In this embodiment, the slide mounting plate 2 is formed so as to slide vertically with respect to the fixed plate 30, and when the curtain rail opening / closing operation cord is extended, the slide mounting plate 2 is slid downward,
By fixing with the fixing screw 21, it is possible to cope with the elongation of the cord.

The case 1 is attached to the fixed plate 30 on the two-wheel 3 side of the curtain rail by the slide mounting plate 2, and in the case 1, a flexible V pulley that engages with the cord for opening and closing the curtain rail, and a cord. A pressing roller that presses against the V pulley, a gear that is formed coaxially with the V pulley, an acceleration spur gear that meshes with the gear, and a sprocket that is formed coaxially with the acceleration spur gear are housed.

The opening / closing operation cord 4 on the two-wheel 3 side of the curtain rail is engaged with the flexible V pulley 5. The cord 4 is pressed against the V pulley 5 by the pressing roller 6 which is biased by the pressing spring 61. Therefore, conventionally, the cord 4 hangs long on the two-car side of the curtain rail as shown in FIG. 3, but in the present embodiment, the cord 4 has flexibility V on the two-car 3 side of the curtain rail. It has only reached pulley 5. Moreover, as described above, when the cord 4 is extended, the slide mounting plate 2 can be slid downward and fixed to the fixing plate 30 with the fixing screw 21, so that the cord 4 can be extended. It is possible to prevent failure or damage. Further, since the cord 4 is pressed against the V pulley 5 by the pressing roller 6 which is biased by the pressing spring 61, it is possible to prevent the cord 4 from being detached from the V pulley 5. Further, since the V pulley 5 is flexible, the force transmission to the cord 4 is reliable.

A gear 7 is arranged coaxially with the V pulley 5, an acceleration spur gear 8 meshes with the gear 7, and a sprocket 9 is arranged coaxially with the acceleration spur gear 8. Further, the ball chain 10 is engaged with the sprocket 9 and
10 is guided by a guide plate 11. Therefore, when the ball chain 10 is operated, the sprocket 9 rotates, and then the acceleration spur gear 8, the gear 7, and the V pulley 5 rotate,
Code 4 moves. Thus, the leading runner 12 provided on the cord 4 is moved in the opening direction or the closing direction,
The curtain can be opened and closed. Here, since the acceleration spur gear 8 is used, the acceleration ratio is possible, and the force transmission is good in both the opening direction and the closing direction of the curtain. Also sprocket 9 and ball chain
Since 10 is used, it can be driven at the time of guidance.
By disposing the operation side drive sprocket 9 on substantially the same surface as the radial surface of the V pulley 5, the action of force can be simplified and the device can be made compact. Further, by using the code 4, it can be combined with an existing stringing system.

[Effects of the Invention] Since the curtain rail operating device for both handing and stringing according to the present invention is configured as described above, it has the following effects.

First, when the curtain rail opening / closing operation cord is extended, the slide mounting plate 2 is slid downward and the fixing screw
By fixing to the fixing plate 30 at 21, it is possible to cope with the elongation of the cord.

Secondly, since the acceleration spur gear 8 is used, an acceleration ratio is possible and the force transmission is good both in the direction of opening and in the direction of closing the curtain.

Thirdly, the cord 4 is pressed against the V pulley 5 by a pressing spring 61.
Since it is pressed by the pressing roller 6 which is urged by, it is possible to prevent the cord 4 from being detached from the V pulley 5. Furthermore, since the V pulley 5 is flexible, the force transmission to the cord is reliable.

Fourthly, since the sprocket 9 and the ball chain 10 are used, they can be driven at the time of guidance.

Fifthly, when the operating-side drive sprocket 9 is arranged on substantially the same surface as the radial surface of the V pulley 5, the action of force can be simplified and the device can be made compact.

Sixthly, by using the code 4, it is possible to use it as an existing stringing system.
