Description

[Detailed description of the invention] The present invention relates to an improvement in the center runner of a vertical blind that opens the slats to both sides by operating a string, and more specifically, to a center runner whose fixed position relative to the string can be easily changed. It is something.

The looped operating cord that opens and closes the slats of the blind is hung on a pulley on one side of the top rail, forming two cords that move in opposite directions within the head rail.

A double-hung vertical blind has two center runners, one of the two cords is locked to one center runner, and the opposite cord is locked to the other center runner. Thus, pulling one of the operating cords opens the blind from the center to both sides, and then pulling the other cord closes the blind from both sides to the center.

The opening/closing condition is adjusted by changing the position of the center runner that locks onto the cord, but as shown in Fig. 4, the conventional locking method uses the center runner 1.
Since the cord 14 was looped around the cord groove 32 of the bottom protrusion 31 of the cord, it was difficult to adjust the locking position, and there was a problem that the opening/closing condition could not be adjusted properly unless one was skilled.

An object of the present invention is to provide a center runner that can be easily and accurately adjusted even by an unskilled person.

In order to achieve the above object, the feature of the present invention is to provide a head rail 20 as shown in FIG.
, an operation string forming two cords 13 and 14 stretched in a loop shape inside the head rail, and two center runners attached to the inside of the head rail so as to be slidable in the longitudinal direction thereof, one center runner. (not shown) is a vertical blind in which one cord 13 side of the operation string is secured and the other cord 14 is secured to the other center runner 10. Parallel side walls 21
A partition wall 22 is provided to connect the above-mentioned both side walls, and guide holes 11 and 12 in the longitudinal direction of the head rail are formed in the both side walls 21 through which the two cords 13 and 14 pass. code room 1
A stopper 16 is inserted into the cord chamber from the bottom so as not to contact one of the cords 13, and the stopper 16 has a groove or hole through which the other cord 14 passes, and is screwed into the groove or hole. This is because a connecting portion 17 consisting of a set screw is provided. Inside the head rail 20 of the vertical blind, the operating cord is stretched in a loop shape and has two cords 13,
Form 14. Although not shown, one center runner attached to the inside of the head rail so as to be slidable in the longitudinal direction is attached to one cord 13.
is locked. The other center runner 10 shown
is similarly attached to the inside of the head rail 20 so as to be slidable in its longitudinal direction. The center runner 10 has both side walls 21 and a partition wall 2 connecting them.
2, and two cords 13, 1 are provided on both side walls 21.
Guide holes 11 and 12 are formed to separate and pass through 4. Both side walls 21 and partition wall 22 have guide holes 11 and 1
A void as a cord chamber 15 is formed inside the cord chamber 2. The bottom of the cord chamber 15 through which the cords 13 and 14 of the center runner 10 pass is opened, and the stopper 16 is inserted into the cord chamber 15 from the bottom. A cord 14 moving in the opposite direction to the cord 13 is passed through a connecting portion 17 of a stopper 16, and the stopper 16 is fixed to the cord 14 with a set screw 18 screwed into the stopper 16. Since the connecting portion 17 is formed in the shape of an L-shaped groove, if the stopper 16 is always attached whenever the cord 14 is passed through the center runner 10, the connecting portion 17 can be removed as shown in FIG. It may also be formed into a hole shape.

When the width of the head rail of the blind is reduced, the two cords 13 and 14 are connected to the center runner 10.
However, since the stopper 16 has an L-shaped vertical section, a void remains on one side of the cord chamber 15. Another cord 13 passing through the cavity can pass freely without being restrained by the stopper 16 at all.

Positioning the center runner 10 of the present invention is extremely easy. First, pull the operating string to close the blind to the center, and manually adjust the center runner 10 to the optimal position. Next, the stopper 16 is inserted into the cord chamber 15 of the center runner 10 from the bottom, and the cord 14 is inserted into the groove of the connecting portion 17. Next, the stopper 16 is fixed to the cord 14 by turning the set screw 18 with a screwdriver and pressing the cord 14 against the ceiling of the groove. Even if the cord 14 is stretched during use and the blind does not close properly, the closed condition of the blind can be easily corrected by loosening the set screw 18 and readjusting the position of the center runner 10.

As described above, the center runner of the present invention is different from conventional cords in which the cord is wrapped around the center runner and fixed, and even an unskilled person can easily adjust the fixing position of the cord.
