DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a locking device for a leading ring runner, and more particularly, to a double-sided or single-opening type curtain when a ring runner shifts a round bar-shaped curtain rail to close a curtain. In addition, the leading ring runner can be locked so as to eliminate the gap at the side edge.

[0002]

2. Description of the Related Art There are various types of locking devices for a leading ring runner. For example, a curtain double-opening type is disclosed in Japanese Utility Model Laid-Open No. 60-139091, Japanese Utility Model Publication No. 5-15815, Japanese Patent Application No. 5-15816, Japanese Utility Model Registration No. 2579795, and the like.

[0003] In these, a locking member with a permanent magnet (hereinafter, the magnet means a permanent magnet) is provided on one of the leading ring runners, and a magnet or a metal plate (iron plate) is also provided on the leading ring runner on the other side. When the curtain is closed from both sides, the magnets of the top ring runner locking tool are attracted to each other by magnetic force near the center when the curtain is closed, and a gap is created at the inner edge of the curtain That is not to be.

[0004]

However, in the above-mentioned conventional locking device for a leading ring runner, it is impossible to attach it to an existing leading ring runner, and it is necessary to replace it with a new ring runner with a locking device. However, removing the existing top ring runner from the rail and installing a new one required considerable effort. Some of them can be attached to the existing leading ring runner, but the installation is still time-consuming, and the production cost is high due to the complicated shape.

The yoke plate attached around the magnet of the locking device has a strong magnetic force. However, if the leading ring runner or the locking device is inclined when the curtain is closed, the surroundings may be damaged. Since a strong magnetic force is concentrated on the yoke portion, the yoke portion is brought into a one-sided contact state with the locking member of the other leading ring runner, and is locked as it is. In this case, a gap was formed at the side edge of the curtain, and the leading ring runner and the locking tool were oblique, resulting in irregular appearance and poor appearance.

[0006] Further, due to the brackets supporting the rails, when the curtain is closed, the leading ring runner can approach only to a state where the bracket is interposed therebetween. For this reason, even if both magnets of the locking tool are attracted to each other, the surface will not be completely attracted, or even if the magnet is attracted, the lower end of the leading ring runner will be greatly pulled, and will be slanted in an inverted C shape. It has become. This still looks bad.

An object of the present invention is to solve the above-mentioned problems of the conventional locking device for a leading ring runner.
That is, the purpose of the invention is to easily apply to the existing top ring runner
Quickly installed, the magnets of the locking tool are not attracted by one side, even if there is a bracket, the magnets will be surface attracted, and at that time the leading ring runner is arranged vertically and looks good. An object of the present invention is to provide a locking tool for a ring runner.

[0008]

SUMMARY OF THE INVENTION A leading ring runner locking tool A according to the present invention is a pair of fasteners which can be attached to a leading ring runner 2 of a curtain using a rod-shaped rail 1,
A hook-shaped hanging member 3 rotatably hung below the leading ring runner 2, a magnet holding member 5 pivotally supported by a lower end of the hanging member 3 on a horizontal axis 4, and a magnet holding member 5. The hook-shaped hanging member 3 is provided with a stopper portion 9 in which the lower portion of the hook-shaped member 3 is inclined toward the curtain closing side when the hook-shaped hanging member 3 is hung on the leading ring runner 2. The magnet holding member 5 is provided with a stopper portion 10 for suppressing an excessive swing angle with the suspension member 3.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the above construction, the locking member A for the leading ring runner of the present invention comprises a pair of left and right symmetrical members. The interior is designed to be opposed.

The leading ring runners 2 to which the locking members A are attached are provided on the rod-shaped curtain rail together with the other ring runners. It is made to wear. Like the other ring runners, the leading ring runner 2 is a ring made of a nonmagnetic metal such as wood, plastic, or brass.

The hook-shaped hanging member 3 is, for example, AB
It is made of plastic such as S resin and has a hook shape with an opening at the lower side.
When the hanging member 3 is hung below the leading ring runner 2, the curtain hook hanging metal fitting 8 attached to the lower part of the leading ring runner 2 is attached to the slot 7.
It can be inserted between them and project downward.

The hook-shaped hanging member 3 has a stopper portion 9 which is locked in such a manner that, when the hook-shaped hanging member 3 is rotatably suspended on the leading ring runner 2, the lower portion is inclined toward the curtain closing side. It is provided. The stopper portion 9 may be configured such that, for example, the lower end edge of the long slot 7 abuts on the curtain hook hanging metal fitting 8 inserted therethrough and is locked, but is not limited thereto.

The magnet holding member 5 supported by the hanging member 3 on the horizontal axis 4 is also made of plastic such as ABS resin. Although the magnet holding member 5 is swingable, the magnet holding member 5 is held at a predetermined angle (for example, 60 degrees) from a vertical position so that the magnet holding member 5 does not swing excessively so as to face the other magnet 6 and repel each other. A stopper portion 10 for locking the swing at about (degree) is provided. The stopper portion 10 is provided, for example, in the vicinity of the pivotal support portion between the magnet holding member 5 and the suspension member 3.
What is necessary is to provide a protrusion that locks the swing of the
It is not limited to that.

The bracket 11 for supporting the bar-shaped rail 1 engaged with the leading ring runner 2 may be provided not only at both ends but also at the center. It is preferable that the horizontal axis 4, the curtain hook hanging bracket 8, the mounting screws (not shown) of the bracket 11 and the like are made of a nonmagnetic metal such as brass, and the curtain hook 14 is made of wood, plastic or It is preferable to use a nonmagnetic metal. The rod-shaped rail 1 is generally made of wood.

The method of attaching the locking member A for the leading ring runner and its operation are as follows. First, in the curtain double-opening type, one pair of the locking members A is attached to each of the leading ring runners 2 on both insides of the ring runners on the rod-shaped rail 1, and in the curtain single-opening type, Is attached to the leading ring runner 2 and the other is attached to the ring runner 2a at one end with the bracket 11 interposed therebetween.

For this installation, the ring runner 2
A curtain hook hanging bracket 8 is attached to the lower part, and the hook-shaped part of each hook-shaped hanging member 3 is opened upward (see FIG. 8), and is engaged with each leading ring runner 2 from below. . At this time, the curtain hanging bracket 8 is engaged with the long slot 7 of the hanging member 3 (see FIG. 9).

When the suspension member 3 is released in the above state, the suspension members 3 and 3 are rotated on the leading ring runner 2 by the weight of the lower magnet holding member 5 and the magnet 6 to form a hook. Hanged at the part. At this time, the suspension member 3
Is provided with a stopper portion 9, so that the lower portion of each of them is inclined to the curtain closing side and locked.
reference).

In the case of the curtain double-opening type, the leading ring runners 2 on both inner sides are locked in a state of forming an inverted U-shape. In the case of the curtain single-opening type, the leading ring runners 2 are inclined toward the curtain closing side. And locked. This is the end of the operation for attaching the leading ring runner locking tool A, and the mounting of the locking tool A can be performed easily and quickly.

Thereafter, the curtain hooks 13 on the upper side of each inner edge of the curtain 11 on each side may be hung on the curtain hook hanging bracket 8 of each leading ring runner 2 having the locking member A.

Next, the operating state of the leading ring runner 2 provided with the locking member A is as follows. When the curtain 11 is closed from both sides, when each leading ring runner 2 approaches the center of the rod-shaped rail 1, when the curtain 11 is closed from both sides, each magnet holding member 5 below each hook-shaped hanging member 3 is used. The magnets 6 inside each other attract and attract each other, and the curtain 12 is maintained without any gap (see FIG. 1).

When the curtain 12 is closed from one side to the other side, when the leading ring runner 2 is moved to the closing side, the magnet under the hook-shaped hanging member 3 is used. The magnet 6 in the magnet holding member 5 below the hook-shaped hanging member 3 suspended from the ring runner 2a at one end with the bracket 11 interposed therebetween,
Then, they suck each other and adsorb each other.
2 is maintained without any gap (see FIG. 2).

In the above case, since the yoke plate is not used in the periphery of each magnet 6 of the locking member A, the magnet 6 has a stronger magnetic force as it approaches the center. Even if the leading ring runner 2 and the locking member A are inclined, the curtain 12 can be closed without any gap by being attracted to the magnet 6 of the runner 2 on the other side.

In addition, each of the locking members A for leading ring runners has a configuration in which each of the hook-shaped hanging members 3 rotatably suspended below the leading ring runner 2 causes the stopper 9 to rotate the hook-shaped hanging member 3 at a fixed angle. , And is preliminarily maintained in an inclined manner toward the curtain closing side (for example, see FIG. 3).

For this reason, even if the two leading ring runners 2 and the ring runner 2a at one end cannot be brought sufficiently close to each other with the bracket interposed therebetween, the magnet holding members 5 attached to the lower ends of the hanging members 3 can be used. Are closer to each other. Therefore, the magnets 6 can be attracted to each other and attracted to each other, and the curtain 12 can be closed so as not to form a gap. Further, the leading ring runners 2 and the ring runner at one end are in an inverted C-shape. It can maintain its vertical shape without tilting and look good.
(See FIG. 2).

Further, in the locking member A for the leading ring runner, in addition to the hook-shaped hanging member 3 being rotatable with respect to each leading ring runner 2 as described above, the magnet holding member 5 is also hooked up. The lowering member 3 is pivotally supported at the lower end.

For this reason, for example, when the bracket 11 is thicker than the above, even if the two leading ring runners 2 and the ring runner 2a at one end cannot be brought close enough,
When the two magnets 6 are attracted to each other by the magnetic force, both the suspension member 3 and the magnet holding member 5 rotate toward each other. That is, the suspension member 3 becomes more inclined than the other side, and the magnet holding member 5 becomes vertical even in that state.

Therefore, also in this case, the two magnets 6 can be attracted to each other with a margin, the curtain 12 can be closed without forming a gap, and the leading ring runners 2 and the ring runner 2a at one end are opposite to each other. The vertical shape can be maintained without tilting in the shape of a square, and the appearance is good (see FIGS. 1 and 2 above).
reference).

The leading ring runner locking device A
In the figure, a stopper 10 for suppressing the swing angle of the magnet holding member 5 to a certain range is provided. Thus, when the hanging member 3 and the magnet holding member 5 attempt to swing excessively when the curtain 11 is closed, the swing of the magnet holding member 5 is suppressed to a certain range (see FIG. 7). The magnets 6 do not face each other with the same pole, and the magnets 6 are prevented from repelling each other.

When the magnets 6 in the two magnet holding members 5 are in the surface-attached state as described above in the case of the curtain double-opening type, the leading ring runner locking tool A is almost heart-shaped when viewed from the front. Because it looks like a shape (for example,
See also).

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows an embodiment of a locking device A for a leading ring runner according to the present invention, which can be attached to each leading ring runner 2 which is fitted on a rod-shaped curtain rail 1 so as to be movable. Consisting of Except for the horizontal axis 4 and the magnet 6, the material is ABS resin here.

Reference numeral 3 denotes a hook-shaped hanging member, which is a hook-shaped portion near the upper portion, which can be rotatably suspended below the leading ring runner 2. A long slot 7 is formed in the upper portion of the hanging member 3, and a shaft supporting portion 15 between the hanging member 3 and the magnet holding member 5 is provided at the lower end.

The long slot 7 of the hanging member 3 is capable of passing a curtain hook hanging metal fitting 8 attached to the lower part of the leading ring runner 2. Further, the lower end edge of the long slot 7 is locked by the curtain hook hanging bracket 8 when the hanging member 3 is hung from the leading ring runner 2 with the lower portion inclined toward the curtain closing side. (See FIG. 3). The oblique shape is
Here, the angle is about 60 degrees with respect to the vertical line.

Reference numeral 5 denotes a magnet holding member, which accommodates the thick disk-shaped magnet 6, and has a short tube portion 15 with a folded edge to the front to prevent it from falling forward, and a cover plate 16 from the rear.
And a shaft support portion 17 at the lower end of the hook-shaped hanging member 3 above the short cylindrical portion 15.

The short cylindrical portion 15 of the magnet holding member 5 has a folded edge portion 18 on the front surface having sufficient strength so that the magnet 6 having a considerably strong magnetic force can be fitted and held.

Further, a shaft support portion 17 on the upper part of the magnet holding member 5
Is supported by the horizontal shaft 4 so as to be swingable with the shaft support portion 14 below the hanging member 3.
In order not to swing too much from the vertical shape, a part of the shaft support portion 17 on the upper part of the magnet holding member 5 is protruded so as to be within a certain angle from the vertical shape, here about 60 degrees. The stopper 10 serves as a stopper 10 which comes into surface contact with a part of the shaft supporting portion 14 below the hanging member 3 to lock the rotation (see FIG. 7).

The magnet 6 in the magnet holding member 5 desirably has a magnetic force as strong as possible even if the volume is small, and a samarium magnet or a neodymium magnet may be used.
Here, a neodymium magnet is used. The magnets 6 in each magnet holding member 5 are housed so that the N pole and the S pole face each other so as to attract each other.

In the above-described embodiment, the locking device A is used for a double-opening curtain. FIG. 2 shows a case where the locking device A is used for a single-opening curtain. Since the use state and operation of the embodiment are the same as those described in the embodiment of the present invention, they are omitted here to avoid duplication.

[0038]

As is apparent from the above, the locking device for a leading ring runner according to the present invention can be easily and quickly attached to an existing leading ring runner, and the magnets come into contact with each other to form a gap in the curtain. Even when the rail has a bracket without any occurrence, both the magnets are attracted to the surface and the curtain can be closed reliably, and the leading ring runner does not become slanted, and the use condition is good.

That is, the conventional locking device for the leading ring runner cannot be attached to the existing leading ring runner, or even if it can be attached, it takes time to attach it. In the case where the yoke plate is attached around the magnets, the magnets hit each other diagonally, leaving a gap between the curtains,
And the appearance was not good either. In addition, the brackets on the rails did not allow both magnets to be attracted to the surface, or the top ring runners on both sides were slanted in an inverted C shape, resulting in poor appearance.

On the other hand, in the locking device for the leading ring runner according to the present invention, the hook-shaped suspending member is engaged with the leading ring runner from below, with the hook-shaped portion being opened upward, and the curtain is closed. All that is required is to engage the hook suspension with the slot. With this, the suspension member is rotated by the weight of the lower magnet holding member and the magnet, and is suspended by each leading ring runner, and the mounting operation is completed. This locking tool can be easily and quickly attached to each of the existing leading ring runners.

The locking device for the leading ring runner is
Since the yoke plate is not used around the magnet, even if the leading ring runner or the locking tool is inclined when closing the curtain, it will not be in a one-sided contact state with the other magnet, but in a surface suction state. Then, each curtain can be securely closed.

The locking device for the leading ring runner is
Since the suspension member suspended rotatably at the lower part of the leading ring runner is provided with a stopper portion which is prevented from rotating at a fixed angle, the suspension member has a lower portion inclined toward the locking side. Has been maintained to be.

Therefore, even if the two leading ring runners cannot come close to each other with the bracket interposed therebetween, the magnets of the magnet holding members below the hanging member are brought closer to each other by the bracket at the center of the rod-shaped rail. The surfaces can be suctioned to each other to perform surface suction. Thus, when the curtain is closed, no gap is formed between the side edges, and each of the leading ring runners does not tilt as in the related art, so that the vertical shape can be maintained and the appearance of the used state is good.

Further, in this magnet holding member, a hook-shaped hanging member is rotatably hung on each leading ring runner, and a magnet holding member is pivotally supported at the lower end of each hanging member. It is. Therefore, even if the bracket is slightly thicker than the above, and the leading ring runner cannot be sufficiently close to each other, when both magnets attract each other, the hanging member and the magnet holding member will rotate with each other, The magnet can be surface attracted with a margin. Thus, also in this case, the curtain can be closed without forming a gap between the side edges, and the ring runner can be maintained in a vertical shape without being inclined in the shape of an inverted C as in the related art, so that the appearance is good. .

Further, the stopper for the leading ring runner is provided with a stopper for suppressing the swing angle of the magnet holding member within a certain range. Therefore, even if the hanging member, the magnet holding member, and the like attempt to swing excessively when closing the curtain, the swing is prevented by the stopper portion, and the magnets in the magnet holding member have the same poles facing each other. The magnets are prevented from becoming in a state of being repelled from each other, and the two magnets can always maintain the attracted state of each other, so that the curtain can be reliably closed without a gap.
