Is formed on an inclined surface 10 which gradually rises from the upper side surface of the rail 1 and continues to the center-side portion 5 at an angle steeper than the other side-side portion 3.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the above construction, the stopper A for the leading ring runner is made of a hard or semi-hard synthetic resin such as a polycarbonate resin, a polyacetal resin or nylon, or a soft resin if the surface is smooth. It is also possible to use a synthetic resin or a metal. If it is made of a synthetic resin, it is desirable to perform injection molding with a mold, but it is not limited thereto. In any case, it is desirable to finish the surface to be smooth so that the frictional resistance of the surface is small.

The front side surface of the stopper A for the leading ring runner is the highest on the central part 5 and smoothly lowers on the both side parts 3, 4 because the leading ring runner 2 moves thereover. It is formed in a horizontally long shape with an inclined surface. When viewed from the side, it is desirable that the leading ring runner 2 is formed in a convex curved shape so as to be fittable.

The two guide legs 7 start from both sides or the lower surface of the rail 1 and gradually increase toward the upper surface of the rail 1 along the outer peripheral surface of the rail 1 to the highest central portion 5. It is formed in an inclined shape so as to be continuous. The guide legs 7 start from both side surfaces of the rail 1 and continue to the central portion 5, but in order to allow the leading ring runner 2 to be more smoothly fitted, the leading end of the leg 7 is required. Instead of starting from both side surfaces of the rail 1, the rail may extend further downward and start from the lower side surface.

A portion 4 near the side of the stopper A for the leading ring, that is, a portion closer to the side where the leading ring runner 2 first passes when the curtain 11 is opened, a portion 3 near the other side, that is, When the curtain 11 is closed, it is desirable to form the head ring runner 2 so as to have a slightly steeper inclination angle than the side portion where the leading ring runner 2 first passes.

The back side surface 6 of the stopper A for the leading ring runner is formed as an arcuate concave curved surface which can be along the outer peripheral surface of the rod-shaped rail 1 at the time of mounting. Also, from the intermediate portion of the guide leg 7, an inclined surface 9 which starts from the upper side surface of the rail 1 and gradually rises and continues to the central portion 5 is formed, and is formed to the guide leg 7 and the central portion 5. They are continuous.

In the figures, 11 is a curtain, 12 is a mounting hole, 14 is a bracket, 15 is a mounting screw, 16 is a hook for a curtain hook, and 17 is a curtain hook.

In the case where the stopper A for the leading ring runner is used, in the case of a double-opening curtain, two pairs of the stoppers A are attached to the upper surface of the central portion of the rod-shaped curtain rail 1 in a facing manner. Here, the opposing shape means that the one side portion 3, that is, the side portion where the leading ring runner 2 first passes when closing the curtain 11 is directed to both outer sides, and the other side portion 4. In other words, when the curtain 11 is opened, the front ring runner 2 may be attached so that the side portion first passing therethrough faces inward, and sandwiches the central bracket 12 (FIGS. 2, 3, 4, and 5). reference).

In the case of a single-opening curtain, one stopper A is provided on the upper surface near one end of the bar-shaped curtain rail 1, and one side portion 3 is directed toward the center of the rail 1. What is necessary is just to attach so that it may face the other side part 4 or the rail 1 side (refer FIG. 6).

The stopper A for the head ring runner is
In order to attach to the upper surface of the bar-shaped rail 1, the screw 15 may be used to fix it to the attachment hole 12 formed in the raised portion of the central portion 5, or it may be attached with a double-sided adhesive tape or other adhesive means. Good.

At the time of mounting, the back side surface 6 of the stopper A for the leading ring runner is formed as a concave curved surface which can follow the outer peripheral surface of the rod-shaped rail 1, so that it does not float up from the outer peripheral surface of the rod-shaped rail 1 so as to be in close contact. It is attached. Since the attached stopper A for the head ring runner has a simple shape and is not bulky, there is no uncomfortable feeling and there is no problem in appearance (see, for example, FIGS. 4, 5, and 6).

The head ring runner stopper A is
When the curtains 11 on both sides are closed when the curtains 11 on both sides are attached to the upper side surface of the bar-shaped rail 1 of the double-opening curtain, the leading ring runners 2 on each side come into contact with the upper side surface of the bar-shaped rail 1 and advance. One side part 3 of the
That is, when the curtain 11 is closed, the leading ring runner 2 attempts to pass through a portion closer to the side where the leading ring runner 2 first passes.

Each leading ring runner 2 at this time is in contact with the upper side surface of the bar-shaped rail 1 as described above, and there is a space 13 between both sides of the bar-shaped rail 1 (see FIG. 7). Therefore, when passing through the side portion 3, the cavities 13 on both sides first engage with the two guide legs 7 starting from both sides of the rod-shaped rail 1 (FIGS. 4 and 5).・ See FIG. 7). In addition, the outer peripheral surface 8 is formed in a convex curved shape that can be engaged into the leading ring runner 2, so that the engagement is performed smoothly.

As described above, initially, when each leading ring runner 2 advances with the guide legs 7 fitted into the cavities 13 on both sides, the leading ring runners 2 remain in contact with the upper side surface of the rod-shaped rail 1 ( 7), the head ring runner 2 proceeds smoothly without any step, vibration, shock or resistance due to engagement with the stopper A.

As each of the leading ring runners 2 further advances, the two guide legs 7 to which they engage are gradually inclined from both side surfaces of the rail 1 to the central portion 5 of the upper surface. Therefore, each of the leading ring runners 2 naturally separates from contact with the upper side surface of the rail 1 and moves onto the guide legs 7 and gradually moves upward along the guide legs 7. , Toward the central part 5 (see FIGS. 4, 5, and 8).

At this time, as described above, the leading ring runner 2
Since the outer peripheral surfaces 8 of the guide legs 7 are engaged in the cavities 13 on both sides of the front ring runner 2, each of the leading ring runners 2 is less likely to sway and proceeds smoothly. In addition, since the inclined surface 9 is formed from the intermediate position (the crotch portion) of the guide leg portion 7 toward the high center portion 5, each leading ring runner 2 is thereafter formed along the same. It progresses toward the upper central part 5.

When each of the leading ring runners 2 reaches the highest portion of the central portion 5 of each stopper A (see FIGS. 4, 5, and 9), then, the other side portion is next shifted. 4, that is, when opening the curtain 11, the leading ring runner 2 moves to the side portion firstly passing therethrough.
Since the side-side portion 4 has a downwardly inclined surface 10 as viewed from the center-side portion 5, each of the leading ring runners 2 slides down along the inclined upper side surface 10 (see FIG. 10), and The bracket 14 comes into contact with and is locked by the bracket 14 (see FIGS. 4 and 5). In this state, each curtain 11 is closed.

The inclined surface 10 of the other side portion 4
Is formed to have a steeper slope than the slope of the other side portion 3, so that it is more difficult to get over the stopper 11 when closing the curtain 11 than when passing through the stopper A. Therefore, for example, even when the curtain 11 is blown by the wind, each of the leading ring runners 2 once in the closed position does not inadvertently climb over the inclined surface 10, and the curtain closed state is maintained. There is no gap at the inner edge (see FIG. 4).

Next, when the curtains 11 are opened, it is necessary for each leading ring runner 2 to climb over the inclined surface 10 of the other side portion 4 as described above. Therefore, if the curtain 11 is opened with a slightly stronger force, each leading ring runner 2 can get over the inclined surface 10 and the curtain 11 can be opened.

The above description has shown the operation in the case of the double-opening curtain. However, in the case of the single-opening curtain (see FIG. 6), the operation is the same as that of the double-sided curtain. Is omitted.

[0028]

4 and 5 show an embodiment of a stopper A for a leading ring runner according to the present invention. FIG. 4 and FIG. 5 show a case where the stopper A is used for a double-opening curtain, and FIG. This is the case when used.

The stopper A is made of synthetic resin or metal, but is made of polycarbonate resin here. Its shape is such that it can be attached horizontally to the upper half surface of the bar-shaped rail 1 in the longitudinal direction, and the portion closer to the center is higher when viewed from the front, and gradually becomes thinner toward the portions closer to both sides.

That is, first, the stopper A for the ring runner has the rear side surface 6 formed in an arc-shaped concave curved surface which can be along the outer peripheral surface of the rod-shaped rail 1, but is slightly smaller than the outer diameter of the rod-shaped rail 1. Is formed into a concave curved surface having a small radius so that it can be joined to the rod-shaped rail 1 in close contact with the side end when it is mounted.

The front side of the stopper A has a rail 1 at one side portion 3, ie, a side portion where the leading ring runner 2 first passes when the curtain 11 is closed.
Are formed starting from both side surfaces of the rail, and the guide legs 7 gradually increase toward the upper surface along the outer peripheral surface of the rail 1 and gradually extend to the central portion 5. It is formed in an inclined shape.

The guide legs 7 are formed so as to start from both side surfaces of the rail 1 and gradually increase toward the upper surface, and have a radius of 50.0 mm near the center portion 5.
The surface is a continuous curved surface. Each outer peripheral surface of the guide leg 7 is formed in a convex curved shape so that the inside of the leading ring runner 2 is easily fitted.

From the intermediate position (crotch portion) of the guide leg 7, a slope 9 is formed, which gradually increases from the upper side surface of the rail 1 and becomes the highest at the portion 5 near the center. The inclined surface 9 is formed so as to be continuous with the guide legs 7 on both sides.

The thickness of the highest part of the uppermost part of the central part 5 is set to about 3.25 mm from the back side surface here. 10 and this is curtain 1
When opening 1, the leading ring runner 2 becomes the side portion 4 that first passes. When viewed from the lower side, this portion starts from the upper side surface of the rail 1 and gradually becomes higher and continues to the above-mentioned central portion 5, where the inclination is about 15 degrees which is steeper than the above-mentioned side portion 3. It is formed at an angle.

The above-mentioned stopper A for the leading ring runner
Is formed on a surface as smooth as possible, is a curved surface without any angular portions, and has a mirror finish.

The stopper A for the leading ring runner
Can be mounted on the upper side surface of the bar-shaped rail 1 by using a screw 15 through a mounting hole 12 provided at a high position of the central portion 5.
May be used, or may be adhered with a double-sided adhesive tape or other bonding means.

This stopper A for the leading ring runner
In the case of a double-opening curtain, two stoppers A are provided on the upper surface of the central portion of the bar-shaped curtain rail 1, and the leading ring runner 2 is first used when closing the curtain 3 on one side. The brackets are mounted facing each other with the central bracket 12 interposed therebetween, with the side portions passing through the central bracket 12 facing outward.

In the case of a single-opening curtain, as shown in FIG. 6, one stopper A is provided on the upper side near one end of the bar-shaped curtain rail 1 on one side portion 3, namely, the curtain 11. At the time of closing, the part near the side that the leading ring runner 2 first passes is attached toward the center of the rail 1.

In any of the above cases, if the stopper A for the leading ring runner is attached, the leading ring runner 2 can relatively easily pass the stopper A for the leading ring runner when the curtain 11 is closed.
Once the curtain 11 has been overcome, the curtain 11 is not overcome to the extent that it is swept by the wind, and the closed state of the curtain 11 is maintained, so that no gap is generated.

[0040]

As is apparent from the above, the stopper for the leading ring runner according to the present invention can be easily and quickly attached to the existing double-opening or single-opening curtain device, and the careless opening and clearance of the curtain can be achieved. Can be prevented, and unlike the conventional one, the number of parts is small, and a strong magnet is not required.
It is smart in appearance and can be installed on the bar-shaped rail without any discomfort.

That is, in the conventional stopper for the leading ring runner, a stopper with a permanent magnet is provided on the leading ring runner, and the stopper is attracted and attracted by magnetic force when the curtain is closed. It is impossible to attach to the ring runner, it takes time to attach,
In addition, the number of components is large and two powerful magnets are required from the structural point of view, so that the cost is high and the assembling work is troublesome.

On the other hand, the stopper for the leading ring runner according to the present invention has the following advantageous effects by being formed in the special shape described above. 1) The stopper for the head ring runner can be integrally formed as a synthetic resin or metal with an extremely simple configuration as described above, so that the manufacturing cost can be reduced, and the mounting can be performed simply by screwing or bonding. ,
The attachment can be performed very easily and quickly, and the use condition can be improved.

2) In the stopper for the leading ring runner according to the present invention, when the leading ring runner first passes through a portion near the side portion when the curtain is closed, the leading ring runner has advanced on the upper side surface of the rod-shaped rail. At first, the vacant space on both inner side portions fits into two guide legs starting from both side surfaces of the rail, and proceeds on the upper surface of the rail as it is. Therefore, the leading ring runner can proceed smoothly without any step, vibration, resistance, or the like due to engagement with the main stopper.

4) In the stopper for the leading ring runner, the two guide legs starting from the side of the rail are:
The height gradually increases toward the upper side of the rail, and continues to the central part. Therefore, as the leading ring runner further advances, it moves away from the upper surface of the rail and naturally moves on to the two guide legs, and can smoothly move to the central portion of the stopper along the same.

5) In the above case, if each outer peripheral surface of the two guide legs is formed in a convex curved shape that can be engaged into the leading ring runner, the leading ring runners can be moved forward. It can travel smoothly with less lateral swing and can get over the central part.

6) Further, in the stopper for the leading ring runner, after the leading ring runner passes through the portion near the center, the leading ring runner slides down the downward slope, and the curtains are closed in this state. Therefore, even if the curtain is blown by the wind, the leading ring runner has resistance to get over the inclined surface, and it is possible to prevent the curtain from being opened or a gap from being created carelessly.

7) In addition, with the stopper for the head ring runner, if the curtain is opened with a slightly stronger force,
Since the leading ring runner gets over the inclined surface, the curtain can be opened.
