Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a curtain runner.

[0002]

[Prior art]

 Conventionally, a curtain runner that hangs a curtain on a curtain rail and opens and closes it, whether it is a sliding type that slides on the rail or a rolling type that has rollers, is used with many runners of the same type arranged on the rail, as is well known. (See, for example, Japanese Utility Model Publication No. 42-4998 and Japanese Utility Model Publication No. 60-185993).

Further, even if the opening / 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 suspending the leading portion of the curtain is added. Similarly, many runners of the same type are used (see, for example, Japanese Utility Model Laid-Open No. 4-45482).

[0004]

[Problems to be solved by the device]

 In the above-mentioned conventional curtain runner, the running condition of the runner became unstable especially when the curtain was opened. That is, when opening a curtain that has been closed, the runners on the side where the curtain begins to open (runners on the side closer to the leading car in the electric system) start traveling on the rail in the direction to open the curtain. After the first runner moves to the position of the next runner, the two runners come into contact with the next runner, run together, move to the position of the next runner, and so on. Will be opened.

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, between each runner and the rail, a dimensionally small gap is formed so that the runner can run on the rail by sliding or rolling in the longitudinal direction. Therefore, as shown in FIG. 19, each runner 1 runs while being dragged by the curtain and tilting in the vertical direction, in other words, tilting in the longitudinal direction of the rail 3, and each runner 1 impairs running stability. As a result, driving becomes less smooth.

Moreover, the curtains gradually overlap with each other as they are opened to form vertical wrinkles (see Japanese Utility Model Publication No. 55-5108). However, if the curtain material is thick, the curtains may be formed before the runners contact each other. Vertical wrinkles overlap each other. Therefore, instead of multiple runners running on the rail together in a row, each runner runs on the rail independently and in an unstable manner, further running while leaning in the longitudinal direction of the rail as described above. , Driving stability was impaired.

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

The present invention is intended to solve the problems of the conventional curtain runner. In other words, the purpose of the present invention is to provide a curtain runner that has a simple structure, but when the curtain is opened, each runner does not tilt in the longitudinal direction of the rail, improves running stability, and enables a light and smooth run. To do.

[0010]

[Means for Solving the Problems]

 The curtain runner according to the present invention is composed of two types of curtain runners 1 and 2 having different shapes. One of the runners 1 is longer in the longitudinal direction of the curtain rail 3 and the other runner 2 is The runners 1 and 2 of the above two types are made shorter, and they are arranged on the rail 3 almost alternately.

In the above configuration, the lateral width w of the runners 1 and 2 near 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 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. The shape can be a combination of inverted trapezoids and trapezoids (or triangular shapes) whose front views have different lateral widths toward the top (see, for example, FIG. 1 and FIG. 2), and whose front views have rectangular shapes with different lateral widths toward the top. 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 almost alternately, they are usually used alternately, but in a combination of rectangular shapes in the front view, the width w is always in the order of long and short. It means that they may be used side by side, such as long / short / short / long, without being arranged side by side.

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

[0014]

[Action]

 The curtain opening and closing device using the curtain runner according to the present invention uses two types of curtain runners 1 and 2 having different shapes arranged on the rail 3 substantially alternately (for example, as shown in FIGS. (See FIGS. 9, 12, 15, and 18).

To open the closed curtain, manually pull the curtain to run the curtain from the runner 1 on the side where the curtain starts to be opened (here, a long runner with a width w is used), and the electric motor. In the formula, runners 1 on the side closer to the leading car (again, runners with a longer width w) are used to start running on the rails 3 in the direction to open the curtain.

When the above-mentioned first runner 1 moves to the position of the next runner 2, the two runners 1 and 2 run together and come into contact with the next runner 2, and further After moving to the position of the runner 1, the three runners 1, 2 and 1 run in contact with the next runner 2, and the carten is opened in sequence.

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 is 2 is shorter. Since the runner 1 having a long lateral width w abuts on the rail 3 with a long width in the longitudinal direction, the runner 1 has a small vertical deviation when traveling, like a long wheelbase of an automobile. There is no inclination, that is, the inclination of the rail 3 in the longitudinal direction. On the other hand, the runner 2 having a short lateral width w is in contact with the rail 3 with a short width in the traveling direction, so that the runner 2 travels lightly on the rail 3 as if the wheelbase of the automobile were short.

Therefore, when these two types of runners 1 and 2 run on the rail 3 together by contacting two or more of them when the curtain is opened as described above, the lateral width w is rather long. 1, the runner 1 has no inclination in the vertical direction and the running resistance is small. On the other hand, the runner 1 having a short lateral width w runs lightly, so to speak, the synergistic effect of the two allows the vehicle to smoothly run on the rail 3 (for example, , FIG. 3, FIG. 6, FIG. 9, FIG. 12, FIG. 15, and FIG. 18).

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 plurality of runners 1 and 2 that abut and run together. Is smooth and the curtains can be opened easily.

In addition, 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 runs without inclining in the longitudinal direction of the rail 3, while the runner 2 having a shorter lateral width w runs lightly on the rail 3, so that the above-mentioned overall In almost the same way, the curtain will open smoothly.

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

[0022]

【Example】

 1 to 9 show a front view formed by two types of curtain runners 1 and 2, which are an inverted trapezoid and a trapezoid or a triangle. 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 vertical side surface I-shaped rail 3, and FIGS. 4 to 6 are also sliding type vertical side surface C-shaped rails. Shows what slides on (means rails with lower opening groove). 7 to 9 show a rolling type rail 3 with a roller 5 and moving on a vertical side I-shaped rail 3. Although not shown, the rolling type rail C also has a vertical side C-shaped rail. May be moved.

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

Of the above, FIG. 10 to FIG. 12 show a sliding type that slides on the rail 3 having a vertical side surface I shape, and FIGS. 13 to 15 also show a sliding type having a vertical side surface C shape. Shown as sliding on rail 3. 16 to 18 show a rolling type roller 3 with a roller 5 that moves on a vertical side surface I-shaped rail 3, and although not shown, it is a rolling type and moves on a vertical side surface C-shaped rail.

[Effect of device]

 As is clear from the above, the curtain runner according to the present invention has a simple structure, and in particular, when the curtain is opened, each runner does not tend to tilt in the longitudinal direction of the rail, and the running stability is increased, which is light and agile. You can drive 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, the running is unstable, and a large force is required for running. Then, it was necessary to install a large motor.

On the other hand, the curtain runner according to the present invention is composed of two types of carten runners having different shapes. One of the lateral widths near the top is longer in the longitudinal direction of the rail, and the other one is The two runners are formed so as to be short, and the runners of the two types are almost alternately arranged on the rails.
