BACKGROUND OF THE INVENTION The present invention relates to an improvement of a curtain runner.

[0002]

2. Description of the Related Art Conventionally, curtain runners that hang a curtain and run on a curtain rail, whether it is a sliding type that slides on the rail or a rolling type with a roller, have the same type of runner on the rail as is well known. Many are used side by side (for example, utility model publication No. 42-4998).
(See Japanese Utility Model Publication No. 60-185993).

Further, in the case where the opening and closing movement of the curtain is not manually performed but is performed electrically by a cord or wire, the same as the above except that a leading vehicle for hanging the leading portion of the curtain is added. Many runners of the same type are lined up and used (for example, actual Kaihei 4-45482
(See the official gazette).

[0004]

[Problems to be Solved by the Invention] In the above-mentioned conventional curtain runner, the running state of the runner becomes unstable especially when the curtain is opened. That is, when opening the curtains that have been closed, the runners on the side where the curtains start to be opened (runners on the side closer to the leading car in the electric opening / closing type) start traveling on the rails in the direction to open the curtains. After the first runner moves to the position of the next runner, the two runners come into contact with the next runner, run together, and then run to the position of the next runner. It will be opened.

When the above curtain is opened, as shown in FIG. 12, the curtain 5 gradually overlaps and forms vertical wrinkles as it is opened (see also Japanese Utility Model Publication No. 55-5108). In addition, each runner 1 that slides or rolls on the curtain rail 4 in the longitudinal direction has a dimension that is slightly movable in the lateral direction of the rail 4, so each runner 1
Is pushed in the lateral direction of the rail 6 by the vertical wrinkles of the curtain 5, and is slightly twisted laterally on the rail 4 and becomes slightly distorted.
This is more likely to happen if the curtain fabric is thick.

By the way, in the conventional runner 1, as shown in FIG. 12, the front part and the rear part are flat,
When the adjacent runners 1 and 1 come into contact with each other, the runners 1 run on the rails 4 independently by simply making point or surface contact. Therefore, each runner 1 tends to turn sideways on the rail 4 when it receives a lateral force, the running resistance becomes large when running on the rail 4 in the longitudinal direction, and the running becomes unstable and does not run smoothly. ing.
Further, since each runner 1 independently travels on the rail 1, it tends to tilt in the vertical direction, in other words, it tends to tilt in the longitudinal direction of the rail, and in this respect, the running stability is poor.

Therefore, particularly when the curtain is opened and closed over a long distance by using a long curtain rail, a large resistance force is generated when the curtain is opened regardless of the manual opening / closing type or the electric opening / closing type, and traveling stability is deteriorated. Therefore, in the case of the electric opening / closing type, the curtain cannot be opened unless a large motor is provided.

The present invention is intended to solve the problems of the conventional curtain runner. That is, the object of the present invention is to prevent the runners from sideways in the lateral direction of the rail sideways to increase the running resistance and impair the running stability, especially when the curtain is opened, with a simple structure. The purpose of the present invention is to provide a curtain runner that can prevent the rail from tilting in the longitudinal direction, improve running stability in this respect, and can smoothly open the curtain with a light force.

[0009]

In the curtain runner according to the present invention, a convex portion 2 is formed on either the front portion or the rear portion of each runner 1, and the convex portion 2 can be engaged with the other. The concave portion 3 is formed so that the convex portion 2 and the concave portion 3 are arranged on the curtain rail 4 so as to be engaged with each other between the adjacent runners 1 and 1.

In the above structure, the convex portion 2 of each runner 1
And the concave portion 3 are formed to be long in the vertical direction, or 2
It is desirable to form them in steps. Further, it is preferable that the length of each runner 1 in the front-rear direction is formed longer.

The runner 1 includes a sliding type and a rolling type with a roller 6. Further, the shapes of the convex portions 2 and the concave portions 3 formed on the front and rear portions of each runner 1 are the same as those of the adjacent runners 1.
As long as they can be engaged with each other, the shape is not limited to the triangular shape (see FIGS. 1 to 9) in plan view, and may be a square shape or a semicircular shape (see FIGS. 10 and 12). . In the figure, 4 is a curtain rail and 6 is a roller.

[0012]

In the curtain opening / closing device using the curtain runner according to the present invention, a large number of runners 1 can be engaged with each other on the curtain rail 4, and the convex portions 2 and the concave portions 3 can be engaged by the adjacent runners 1, 1. (See Fig. 2, Fig. 5, Fig. 7,
(See FIG. 9).

When the curtain 5 is opened, in the manually openable type, when the curtain is pulled, the curtain starts to be opened from the runner 1, and in the electrically openable type, the string is moved by the drive motor to move the leading vehicle and the leading vehicle moves. The runners 1 on the side closer to the car start traveling on the rails 4 in the direction to open the curtain.

When the first runner 1 travels to the position of the next runner 1, the two runners 1, 1 run together as they come into contact with the next runner 1, and the next runner 1 also runs. When the vehicle runs to the position, the runner 1 comes into contact with the runner 1, and the three runners 1, 1, 1 travel together, and the curtain is sequentially opened.

In the above case, the curtain runner 1 according to the present invention has the convex portion 2 formed on either the front or rear portion thereof and the concave portion 3 formed on the other thereof, and the adjacent runners 1, 1 are The convex portion 2 and the concave portion 3 can be engaged with each other.

Therefore, when the running runner 1 comes into contact with the next runner 1, the convex portion 2 and the concave portion 3 are engaged with each other, so to speak, they are almost connected and integrated (FIG. 2 and FIG. 2). 3 ・ Fig. 5, Fig. 7, Fig. 9, Fig. 11). Unlike the single runner that is free on the rail, the multiple runners 1, 1, 1 linked and integrated by this engagement are different from the rail 4
In the above, movement in the lateral direction is largely restricted.

Therefore, the runners 1 are hardly laid sideways even when subjected to a force in the lateral direction of the rails 4 due to the vertical wrinkles formed as the curtain opens, and the runners 1 are placed on the rails 4. There is almost no running resistance when running in the longitudinal direction, and it runs lightly and smoothly.

Further, the convex portion 2 and the concave portion 3 of each runner 1 are formed to be long in the vertical direction (see, for example, FIGS. 1 and 10), or are formed in two steps, upper and lower (see, for example, FIG. 4 and FIG. 8), the adjacent runners 1 and 1 are in an engaged state in which they are in contact with each other in a long area in the vertical direction when engaged (see FIG. 3). Therefore, the plurality of engaged runners 1, 1, 1 are less likely to be tilted in the vertical direction during traveling, in other words, are not tilted in the longitudinal direction of the rail 4,
In this respect, the driving stability is increased and the vehicle runs smoothly.

Further, if each runner 1 is formed to have a long length in the front-rear direction (see, for example, FIG. 4), the vertical wrinkles formed as the curtain is opened do not disturb the runners 1, 1 adjacent to each other. The convex portion 2 and the concave portion 3 are engaged with each other. That is, in the conventional runner, the vertical wrinkles of the curtains come into contact with each other before the runners come into contact with each other when the curtain is opened, and the runner is pushed or pulled by the curtain, which makes the running unstable. became. But each runner 1
If the length in the front-back direction is made longer, the adjacent runners 1 and 1 engage with each other at the convex portion 2 and the concave portion 3 before the vertical wrinkles of the curtain come into contact with each other to connect and integrate them. Will end up.
Therefore, each runner 1 also has improved running stability and runs smoothly.

[Effects of the Invention] As is clear from the above, the curtain runner according to the present invention has a simple structure, but when the curtain is opened, there is almost no running resistance between the runners and the rails and running stability. It is also increasing, and you can drive smoothly and lightly. There is no need to upsize the motor even when opening curtains on long rails.

That is, in the conventional curtain runner, when the curtain is opened, each runner tends to be laterally in the lateral direction of the rail, or tilts up and down, in other words, the rail is tilted in the longitudinal direction. It happened. for that reason,
Each runner had great running resistance and required a large amount of force, and the running was unstable as it was pushed or pulled by the vertical wrinkles of the curtain, and the curtain could not be opened smoothly. Also, especially when opening curtains with long rails,
It was necessary to upsize the motor.

On the other hand, the curtain runner according to the present invention is provided with the convex portion and the concave portion which can be engaged with the front portion and the rear portion of each runner. The part and the recess are engaged to connect and integrate. Therefore, even when a force is applied to each runner in the lateral direction of the rail when opening the curtain, each runner is prevented from lying sideways, and there is almost no running resistance on the rail, and running stability As it increases, you can open the curtain smoothly with a light force. There is no need to upsize the motor when opening curtains on long rails.

Further, if the front and rear projections and recesses of each runner are long in the vertical direction or formed in upper and lower two steps, each runner is in a long vertical engagement state when engaged. become. Therefore, it is possible to prevent each runner from tilting in the vertical direction, in other words, tilting in the longitudinal direction of the rail, and to improve running stability and smooth running in this respect as well.

Further, if each runner is formed to have a long length in the front-rear direction, adjacent runners can engage with each other by the convex portion and the concave portion even if vertical wrinkles are formed as the curtain is opened. , The runner is no longer pushed or pulled by the vertical wrinkles on the curtain. Therefore, in this respect as well, each runner has improved running stability and can run smoothly.
