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 on a curtain rail and move it open and close, whether it is a sliding type that slides on the rail or a rolling type with rollers, 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. 42-4
(See Japanese Patent Publication No. 998 and Japanese Utility Model Publication No. 60-185993).

Further, even if the opening and closing movement of the curtain is not manually performed but is electrically driven by a motor through a string or wire, the above-mentioned method is used except that a leading vehicle for hanging the leading portion of the curtain is added. Similarly, many runners of the same type are used (for example, actual Kaihei 4-4548).
No. 2).

[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 curtain which has been closed, the runners on the side where the curtain starts to be opened (the runners on the side closer to the leading car in the electric type) start traveling on the rail in the direction to open the curtain. After the first runner moves to the position of the next runner, it abuts the next runner and the two runners run together,
Furthermore, the curtain moves to the position of the next runner, and this is repeated to open the curtains one after another.

When the curtain is opened as described above, whether it is a manual type or an electric type, the opened curtain runs on the rail while dragging or pushing each runner.

However, the runners and the rails are formed with a slight gap in dimension so that the runners can slide or roll on the rails in the longitudinal direction. Therefore, as shown in FIG. 19, each runner 1 is dragged by the curtain and tilts in the up-down direction, in other words, tilts in the longitudinal direction of the rail 3, and each runner 1 is impaired in running stability. Will not run smoothly.

Moreover, the curtains gradually overlap with each other as they are opened to form vertical wrinkles (Actual Publication 55-5108).
However, if the curtain material is thick, the vertical wrinkles of the curtain overlap before the runners contact each other. Therefore, instead of multiple runners running on the rail together, each runner runs on the rail independently and unstablely. , Driving stability was impaired.

[0008] Particularly in the case of a curtain on a long rail, running resistance also becomes large, so that a large force is required to open the curtain, and in the case of an electric type, it is necessary to provide a large motor.

The present invention is intended to solve the problems of the conventional curtain runner. That is, an object of the present invention is to provide a curtain runner which has a simple structure but does not allow each runner to tilt in the longitudinal direction of the rail when the curtain is opened, which improves running stability and allows a light and smooth running. It is in.

[0010]

The curtain runner according to the present invention comprises two types of curtain runners 1, 2 having different shapes.
2, the runner 1 has a lateral width w that is long in the longitudinal direction of the curtain rail 3 and the other runner 2 is short, so that the above-mentioned two types of runners 1 and 2 are almost on the rail 3. It is designed to be used alternately.

In the above structure, the lateral width w of the runners 1 and 2 near the upper portion is such that one runner 1 is longer in the longitudinal direction of the rail 3 and the other runner 2 is shorter, and the lateral width w of the former 1 is the latter. The width w of 2 is, for example, about 1.5 times or more. As for the shape, even if the front view has a different lateral width toward the upper part, for example, a combination of an inverted trapezoid and a trapezoidal shape (or a triangular shape) (see, for example, FIGS. 1 and 2), the front view has a rectangular shape with a lateral width closer to the upper part. A combination of shapes (see, for example, FIGS. 10 and 11) may be used.

When the two types of runners 1 and 2 are used in a substantially alternating arrangement, they are usually used in an alternating arrangement.
It does not have to be arranged in the order of long / short, but it may be arranged and used, for example, long / short / short / long.

It is desirable that each of the two types of runners 1 and 2 be formed such that its length in the vertical direction is long. In the figure, 3 indicates a curtain rail and 5 indicates a roller.

[0014]

In the curtain opening / closing device using the curtain runner according to the present invention, a large number of curtain runners 1 and 2 of two different shapes are arranged almost alternately on the rail 3 (see, for example, FIG. 6, FIG. 9, FIG. 12, and FIG.
-See Figure 18).

When opening a closed curtain,
In the manual type, pulling the curtain starts the runner on the side where the curtain starts to be opened (here, a long runner with a width w is used) 1, and with the electric type, the runner on the side closer to the leading car (again, the width w 1 uses a long runner) and starts running on the rails 3 in the direction of opening the curtain.

When the first runner 1 moves to the position of the next runner 2, the two runners 1 and 2 run together as they come into contact with the next runner 2.
Further, when it moves to the position of the next runner 1, it comes into contact with the next runner 2 and the three runners 1, 2 and 1 run together, and the curtain is sequentially opened.

In the above case, the curtain runner according to the present invention is composed of two types having different shapes, and the lateral width w toward the upper part is such that one runner 1 is longer in the longitudinal direction of the rail 3 and the other runner 2 is It is short. Since the runner 1 having a long lateral width w is abutting with a long width in the longitudinal direction of the rail 3, it is as if the wheelbase of the automobile is long, so that there is little blurring in the vertical direction during traveling and the vertical direction in the vertical direction. The vehicle runs with no inclination, that is, no inclination in the longitudinal direction of the rail 3. On the other hand, since the runner 2 having a short lateral width w is in contact with the rail 3 with a short width in the traveling direction, the runner 2 travels lightly on the rail 3 as if the wheelbase of the automobile is short.

Therefore, the two types of runners 1 and 2 are
However, when two or more pieces come into contact with each other and travel together on the rail 3 when the curtain is opened as described above, the lateral width w is long and there is no inclination in the vertical direction due to the runner 1, and the traveling resistance is small. On the other hand, the runner 1 having a shorter width w runs lightly, and so to speak, it smoothly runs on the rail 3 due to the synergistic effect of the two (see, for example, FIG.
See FIG. 6, FIG. 9, FIG. 12, FIG. 15, and FIG.

This is the same for both the manual type and the electric type, and when the runners 1 and 2 are dragged by the curtain and run, the movement of the runners 1 and 2 that abut and run together. Is smooth and the curtains can be opened easily.

Further, when the runners 1 and 2 cannot come into contact with each other due to the vertical wrinkles formed when the curtain is opened, the runners 1 and 2 cannot run continuously together, that is, the runners 1 and 2 run independently on the rail 3. Even when traveling, the runner 1 having a longer lateral width w travels without inclining in the longitudinal direction of the rail 3, while the runner 2 having a shorter lateral width w travels lightly on the rail 3, so that it is almost the same as the above. Similarly, the curtain will be opened smoothly.

If the runners 1 and 2 are formed to be long in the vertical direction, the rail 3 is further inclined in the longitudinal direction when two or more runners come into contact with each other. It becomes difficult and you can run more smoothly.

[0022]

1 to 9 show a front view formed by two types of curtain runners 1, 2 having an inverted trapezoidal shape and a trapezoidal shape or a triangular shape. The inverted trapezoidal runner 1 has a longer lateral width w toward the upper portion, and the trapezoidal or triangular runner 2 has a shorter lateral width w toward the upper portion.

Of the above, FIGS. 1 to 3 show a sliding type slide on a rail 3 having a vertical side surface I, and FIG.
From FIG. 6 to FIG. 6, there is shown a sliding type rail which slides on a vertical side C-shaped rail (which means a rail having a lower opening groove) 3. Further, FIGS. 7 to 9 show a rolling type rail with a roller 5 which moves on a vertical side surface I-shaped rail 3. Although not shown, the rolling type rail-shaped vertical side surface C-shaped rail 3 is also used. It may be mobile.

Next, FIGS. 10 to 18 show the shape of the front view formed by two types of rectangular runners 1 and 2 each having a lateral width w near the upper portion and a short width.

Of the above, FIGS. 10 to 12 show a sliding type slide on the vertical side I-shaped rail 3, and FIGS. 13 to 15 show the same sliding type vertical side C-shaped rail. 3 shows what slides on. 16 to 18 show a rolling type roller 3 with a roller 5 which moves on a vertical side surface I-shaped rail 3. Although not shown in the drawings, the rolling type vehicle moves on a vertical side surface C-shaped rail. It may be one.

[0026]

[Effects of the Invention] As is clear from the above, the curtain runner according to the present invention has a simple structure, and particularly when the curtain is opened, each runner does not tend to tilt in the longitudinal direction of the rail, which improves running stability. You can drive lightly and smoothly.

That is, in the conventional curtain runner, each runner tends to incline in the longitudinal direction of the rail, especially when the curtain is opened, and the running is unstable and a large force is required for running. It was necessary to install a motor.

On the other hand, the curtain runner according to the present invention is composed of two types of curtain runners having different shapes, and one of the lateral widths near the upper part is long in the longitudinal direction of the rail and the other is short. The runners of the two types are arranged on the rails almost alternately and are used.
