Description

Detailed Description of the Invention Technical Field The present invention relates to an opening/closing device for curtains or draperies having two parts that move in mutually opposite directions. As such, there is a device comprising a cord having a first end connected to a grip or button on one part of the curtain and a second end connected to a clip or button on the other part of the curtain.

Such devices are widely known and are
The clip or button is coupled to a length of tape commonly used to adjust the position of the user, or the tape is used for positioning.

Curtain control devices consisting of panels or strips are also known. The device includes a threaded bolt for horizontally moving the panel or strip, and further for changing the orientation of the panel or strip with or independent of opening and closing of the curtain. Mechanisms are provided as necessary.

However, in these devices, the control bolt is provided with a flat screw. Thus, in order to open a curtain, all the holes or strips must be moved simultaneously in one direction, and in order to close the curtain, they must be moved simultaneously in the other direction. Although similar devices are known, none of them are suitable for the need to open and close a curtain or drapery by moving the two parts in opposite directions.

The present invention opens and closes a curtain or a curtain having two parts by moving the two parts in mutually opposite directions.
- It is an object of the present invention to provide a courtesy opening/closing device K that can be easily and quickly operated.

The object of the present invention is to provide a device for controlling the opening and closing of a curtain, which has two parts that move in opposite directions, and which is supported in an I-men style and is substantially horizontal when in use. a rotatable 0-piece placed on the 0-piece, and a rotatable 0-piece movably mounted on the 0-piece without rotating;
the gripper comprises at least two sliders connected to the two parts of the curtain; the rod comprises 2' threads each having one or more starting points; The rod is formed as a right-handed thread and a left-handed thread having an intersection point over substantially the entire length of the rod, and the slider is configured such that the first slider moves in opposite directions along the zero end of the rod. A second slider is guided by one screw and a second slider is guided by the other screw of the zero point, and each slider opens or closes the curtain according to the direction of rotation of the zero point. This is achieved by a curtain opening/closing device characterized by:

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows a curtain having two parts (1) and (2) that are moved in opposite directions to open and close. . The control device according to the invention comprises a rotatably threaded control head (3) supported by a support section member (4). The support section member (4) is in the longitudinal direction. It can be installed so that the axis is horizontal. therefore,
The member (4) can be attached, for example, directly or indirectly to the ceiling of the room or to a fitting above the window on which the curtain is hung.

The threaded bolt (3) has a first threaded portion (5) with one or more starting points. As shown, the threaded portion (5) is formed as a right-handed thread.

The thread (3) further comprises a second threaded portion (6) having one or more starting points. The second threaded part (6) is formed as a left-handed thread, contrary to the first threaded part.

The two threaded portions (5), <6) have the same pitch and intersect at numerous points over the entire length of the screw thread (3). The rod (3) is supported at its end by a support (7). The support (7) is formed inside the channel (8) in the support section member (4). If necessary, a support (7) can be provided midway between the ends of the rod (3) to support the rod (3). A longitudinally extending cavity is formed in the lower part of the channel (8). 0 at one end of (3)
- A roller or pulley (9) is fixed, through which the chain or cord passes. The chain or cord αO can be moved to control the rotation of the shaft (3) in both directions, allowing the two parts (1), (2) of the curtain to be moved as desired.

The two sliders Oυ and θ are movable and 0 (
3) It is installed on the 0-piece (3) to prevent it from rotating. These slides (il), (6) are attached to the arms (1'l'), (12'), respectively, as shown.
These arms (11
'), (12') extend through a longitudinal cavity formed in the lower part of the channel (8) of the support section member (4). As a result, the rotation of the sys writer 0η, (6) is restrained, and the slider 0υ, Q2 can be guided along the longitudinal direction of the sys writer 0η, (3). These sliders α9, (6), more precisely arms (11'), (1
A clipper (2), H is attached to the clipper (2'), and the two parts (1) of the clipper (2') and a
), (2) are retained. The two parts (1) and (2) of this curtain are in a state of instantaneous alignment with each other when the curtain is closed. In addition to the clippers aa and C+, a holder that can similarly hold a curtain can be used. The sliders a), (2) each have on their inner surface at least one tooth or thread, aQ, which meshes with the right-hand and left-hand threads on the rod (3), respectively.

As described above, when the shaft (3) rotates in one direction due to the operation of the chain or cord QO passing through the O-ra or pulley (9), the slides 4a1), ( company)
simultaneously move in opposite directions, that is, away from each other, to open the curtsey. When the rod (3) is rotated in the opposite direction, the two sliders (b)
, Q move closer to each other and close the curtains.

Attachment and support units (17) are mounted on the curtain at appropriate intervals to ensure retention of the two parts (1), (2) of the curtain. The unit 0η can be a clipper that slides loosely on the rod (3) or a clipper that slides along a groove provided in the support section member (4).

The support section member (4) can have various cross-sectional shapes as shown in FIGS. 2.4 and 5. The cross-sectional shape chosen depends on the type of curtain and the structure and position of the attachment for attachment to the ceiling or covering fittings.

Effects of the Invention As is clear from the above, according to the present invention, the curtain can be opened and closed easily and quickly by using a single screw having right-handed and left-handed screws and rotatable in both directions. be able to. .
