Abstract

PROBLEM TO BE SOLVED: To provide a runner for a curtain rail, capable of reducing a folding margin of a curtain regardless of the size of a curtain rail. SOLUTION: This runner 3 for a curtain rail is formed of a body 4 inserted to freely run inward from the side end in the longitudinal direction of the curtain rail 1, and a curtain hanger 5 suspended from the lower part 6 of the body projected from a curtain rail groove 2. The lower part 6 is provided with a wing 7 projected in the longitudinal direction, the tip of which is bent upward along the front and rear surfaces of the curtain rail. The lateral width of the runner 3 is set smaller than the longitudinal width of the curtain rail groove 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curtain rail runner capable of reducing the folding margin of a curtain.

[0002]

2. Description of the Related Art When a curtain is opened, in order to reduce the accumulation of curtains that have gathered, it is necessary to reduce the width of the runner in the left-right direction when the longitudinal direction of the curtain rail is the left-right direction. However, if the left and right width of the runner is smaller than the front and rear width of the groove on the curtain rail, if the runner turns 90 degrees while closing the curtain, the runner will come off the curtain rail. It was not possible to make it smaller than the front-back width. Therefore, if the front-rear width of the groove of the curtain rail is reduced, the size of the curtain rail is related to the front-rear width of the groove. The folding allowance could not be reduced.

[0003]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and its object is to reduce the folding margin of a curtain that has been opened and closed regardless of the size of the curtain rail. The purpose is to provide a runner for a curtain rail that can be used.

[0004]

Means for Solving the Problems In order to achieve the above object, the means adopted by the present invention is movably inserted inward from the side end of the curtain rail when the longitudinal direction of the curtain rail is the left-right direction. The main body and a ring hung at the bottom of the main body that hangs through the groove of the curtain rail,
In a curtain rail runner consisting of hooks, clips, and other curtain hangings, a wing that protrudes in the front-rear direction at the bottom and then bends upward along the front-rear surface of the curtain rail is integrally formed. The width is smaller than the front and rear width of the curtain rail groove. Preferably, the wings are formed symmetrically with respect to a vertical plane that includes a centerline that bisects the curtain rail from front to back.

With the above means, when the runner of the present invention tries to rotate while the curtain is being closed, the tips of the wings come into contact with the front and rear surfaces of the curtain rail and prevent the rotation, so that the width of the runner is reduced. Even if the width is smaller than the front and rear width of the groove of the curtain rail, there is no possibility of coming off the groove of the curtain rail.

When the curtain is opened and brought to one side, the runners line up in close contact with each other. The total width of the runners on the left and right corresponds to the folding margin of the curtain, but since the width of each runner is narrower than the front and rear width of the curtain rail groove, the conventional left and right width is smaller than the front and rear width of the curtain rail groove. Compared to the full width of large runners closely aligned with each other, it is much narrower. Therefore, the folding margin of the curtain using the runner of the present invention is significantly smaller than that using the conventional runner.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described based on the embodiments shown in the drawings.

1, 2 and 3 are a front view, a bottom view and a side view of a curtain rail equipped with a runner according to an embodiment of the present invention.

The curtain rail 1 shown in FIG. 1 is exactly the same as the conventional one, and has a groove 2 at the center of the bottom surface which is equal to the entire length of the curtain rail 1. The height and front-rear width of the curtain rail 1 may be larger or smaller depending on the size of the groove 2.

The lateral width of the runner 3 in the longitudinal direction of the curtain rail is smaller than the longitudinal width of the groove 2 of the curtain rail 1.
The runner 3 is composed of a main body 4 and a curtain hanging device 5 suspended from the main body, like the conventional one.

The main body 4 has an upper part which runs on the runner running surface of the curtain rail 1 inside the curtain rail 1.
It consists of a lower part 6 which passes from the upper part thereof through the groove 2 of the curtain rail 1 and hangs down. The curtain hanging device 5 is hung on the lower portion 6.

Wings 7 project from the lower portion 6 in the front-rear direction. The wings 7 are symmetrical with respect to a vertical plane including the center line of the curtain rail 1 in the longitudinal direction, and the tips on both sides are bent along the front and rear surfaces of the curtain rail 1.

Although not shown, when the curtain is opened and brought close to one side of the curtain rail, the runners are in close contact with each other,
The curtain is folded. The folding margin of this curtain corresponds to the total width of the runners that are arranged in close contact with each other in the longitudinal direction of the curtain rail.

Since the width of the runner 3 of the present invention shown in FIGS. 1 and 2 in the left-right direction is smaller than the front-back width of the groove 2 of the curtain rail 1, the length in which the runners 3 of the curtain are closely attached to each other is determined. The length is much shorter than the conventional length in which the runners of the curtain, which are wider than the front and rear widths of the groove 2 of the curtain rail 1, are arranged in close contact with each other. Therefore, the runner 3 of the present invention can significantly reduce the folding margin of the curtain as compared with the conventional runner. Since the runner 3 includes the wings 7 along the front and rear surfaces of the curtain rail 1,
If the runner 3 tries to rotate while the curtain is being closed, both ends of the wings 7 come into contact with the front and rear surfaces of the curtain rail 1 and stop the rotation, so the runner 3 rotates 90 degrees and comes off the curtain rail 1. That's not it.

As shown in FIG. 3, the runner 3 can be freely attached and detached in the longitudinal direction through the side end of the curtain rail 1. As shown in FIGS. 1 and 2, the runner 3
If the cap 8 is attached to the side end of the curtain rail 1 after mounting, the runner 3 can be prevented from falling off the curtain rail 1 in advance.

[0016]

As described above, in the conventional runner, if the width in the longitudinal direction of the curtain rail is made smaller than the groove width of the curtain rail, it will come off the curtain rail when rotated, so that the width in the longitudinal direction of the curtain rail will be reduced. Since it was wider than the rail groove width, the folding margin of the curtain could not be reduced. In contrast,
The runner of the present invention has a width of the runner smaller than the groove width of the curtain rail, and the wings prevent the runner from rotating to prevent the runner from falling off. Also on the rail,
It has an excellent effect that the folding margin of the curtain can be made significantly smaller than the conventional one.
