Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curtain suspension opening / closing device.

[0002]

2. Description of the Related Art A conventional curtain suspension opening / closing device generally has a curtain rail 1 and a runner 2 mounted on the curtain rail 1 so as to be movable back and forth, as shown in FIG.
And the stop member 4 provided on the runner 2 on the side of the curten 3.
It is comprised by the stop member 5 which engages / disengages with the. Specifically, the web 10 in which the curtain rail 1 is oriented horizontally
And a pair of flanges 11 and 11 continuous from the left and right ends of the web 10 to the lower side, and extending pieces 13 and 13 continuous from the rear ends of the flanges 11 and 11 in a direction opposite to each other with an opening 12 therebetween. The runner 2 is formed in a substantially channel-shaped cross section including
A pair of left and right rolling wheels 20, which are rotatably supported by
And a horizontal support shaft 21 that supports the rolling wheels 20 and 20 so that they can rotate simultaneously, a suspension member 22 that allows the horizontal support shaft 21 to relatively rotate between the rolling wheels 20, 20, and a rotation around the vertical axis. And a suspension ring 23 suspended from the suspension member 22 so that
The stopper member 4 on the side of the carten 3 is detachably suspended from the suspension ring 23. Therefore, the rolling wheels 20,
20 is rotatably supported by the extending pieces 12 and 12 of the curtain rail 1, and the hanging member 22 is opened from the opening 12 to the curtain rail 1.
The runner 2 is assembled to the curtain rail 1 in a state of being projected downward, and the stop member 5 on the runner 2 side made of, for example, an adhesive cloth and the stop member 4 on the curtain 3 side made of an adhesive cloth are integrally combined. By doing so, the curtain 3 is suspended so that it can be opened and closed.

However, in the above-mentioned conventional curtain suspension opening / closing device, the web 10 of the curtain rail 1 having a substantially channel-shaped cross section is oriented horizontally. That is, since the web 10 is orthogonal to the load application direction, the section modulus and bending stress (skin stress) are small. for that reason,
Since it is necessary to increase the wall thickness to increase the rigidity, the cost of the curtain rail 1 becomes high. In addition, when the curtain rails 1 are arranged in parallel, a double-track structure has a problem that the curtain rails 1 interfere with each other when installing furniture, furniture, or the like because the amount of projection to the inside of the room becomes large. On the other hand, the runner 2 has a large number of parts, a complicated structure, is complicated to manufacture and assemble, and has a drawback of high cost.

[0004]

The problem to be solved is that since the curtain rail has a small section modulus and bending stress, the wall thickness must be increased to increase the rigidity.
The cost of the curtain rail is high, and the double track structure with the curtain rails in parallel, for example, increases the amount of overhang to the interior side, which increases the degree of interference with furniture and furniture, and the number of runner parts is large. The structure is complicated, the manufacturing and assembling are complicated, and the cost of the runner is high.

[0005]

According to a first aspect of the present invention, there is provided a curtain rail, a runner incorporated in the curtain rail so as to be movable back and forth, and a stopper member provided on the runner, which is provided on the curtain side. In the curtain suspension opening / closing device configured with a stop member, a web in which the curtain rail is oriented vertically, a pair of flanges continuous from the upper and lower ends of the web to the rear side, and an opening from the rear end of these flanges. And a rolling wheel that is formed in a substantially channel-shaped cross section and that has run-out pieces that are continuous in a direction opposite to each other with the runner rotatably supported by the lower flange of the curtain rail. Rotatably supporting the horizontal support shaft protruding from the opening to the rear side of the curtain rail, and fixed to the protruding portion of the horizontal support shaft and extending to the lower side of the curtain rail. And a stop member is provided on the lower front surface of the hanger. By increasing the rigidity of the curtain rail, the cost is reduced, and the curtain rail has a double-track structure. The purpose is to reduce the amount of overhang in the case, reduce the degree of interference with furniture, furniture, etc., reduce the number of runner parts, simplify the structure to facilitate manufacturing and assembly, and reduce the cost of the runner. Was achieved. The invention according to claim 2 is characterized in that the curtain rails are formed in a substantially channel-shaped cross section of two upper and lower rows, and the rigidity is further enhanced.

[0006]

According to the invention of claim 1, the web is directed vertically. That is. Since the web is oriented in the load application direction, the section modulus and bending stress increase.
Further, in the case of a double-track structure in which they are arranged in parallel, it is possible to suppress the amount of overhang to the indoor side, for example. On the other hand, the runner can be simply constructed with three parts, a rolling wheel, a horizontal support shaft and a hanger. According to the invention of claim 2,
The section modulus and bending stress are larger than those of a curtain rail formed in a series of substantially channel-shaped sections.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view showing an embodiment of a curtain rail,
FIG. 2 is a front view of the runner, and FIG. 3 is a sectional view of the use state. It should be noted that the same or corresponding portions as those in the conventional example will be described by attaching the same reference numerals. 1 to 3, a curtain suspension opening / closing device includes a curtain rail 1 and a runner 2 mounted on the curtain rail 1 so as to be movable back and forth.
The runner 2 includes a stop member 5 which is engaged with and disengages from a stop member 4 on the side of the curten 3.

The curtain rail 1 is manufactured by extrusion molding using an aluminum-based metal or a synthetic resin so as to have a uniform cross-sectional shape in the longitudinal direction.
And a pair of flanges 11 and 11 that are continuous from the upper and lower ends of the web 10 to the rear side, and extending pieces 13 and 13 that are continuous from the rear ends of the flanges 11 and 11 in a direction facing each other with an opening 12 therebetween. And a substantially channel-shaped cross section.

The runner 2 rotatably supports the rolling wheel 20 on the lower flange 11 of the curtain rail 1, and rotatably supports the rolling wheel 20, and extends from the opening 12 to the rear side of the curtain rail 1. A horizontal support shaft 21 that protrudes and a hanger 24 that is fixed to the protruding portion 21A of the horizontal support shaft 21 and extends in a crank shape below the curtain rail 1 are provided. The stop member 5 made of is attached by an adhesive material.

Further, the web 10 of the curtain rail 1 has locking portions 6 and 6 formed at both upper and lower end portions on the front side. Therefore, the decorative plate 7 can be attached and detached. In the figure, 8 indicates a bracket.

With such a structure, the rolling wheel 20 is rotatably supported by the lower flange 11 of the curtain rail 1, and the projection 21 of the horizontal support shaft 21 extends from the opening 12 to the rear side of the curtain rail 1. Curtain rail 1 in the projected state
By incorporating the runner 2 in the above and integrally connecting the stop member 5 on the runner 2 side made of an adhesive cloth and the stop member 4 on the curtain 3 side made of an adhesive cloth, the curtain 3 can be hung openably and closably. .

In the present invention, the web 10 is oriented vertically. That is, since the web is oriented in the loading direction of the load, the section modulus and bending stress increase. Therefore, high rigidity can be secured even if the wall thickness is reduced. Thereby, the cost of the curtain rail 1 can be reduced. Also,
Even if the curtain rail 1 is manufactured by extrusion molding of a synthetic resin, it is possible to obtain a high rigidity that can be used. With the curtain rail 1 made of synthetic resin, the corner portion 1A can be formed by curving the linear curtain rail 1 except for the case where the radius of curvature of the corner portion 1A shown in FIG. 4 is extremely small. Therefore, it is possible to save the trouble of separately manufacturing the corner portion 1A and the troublesome labor of connecting both ends of the manufactured corner portion 1A to the straight portions.

On the other hand, by orienting the web 10 in the vertical direction, even if the curtain rails 1 are arranged in parallel as shown in FIG. Therefore, it is possible to avoid the curtain rails 1 from interfering with each other when installing furniture or furniture. Moreover, since the runner 2 is simply configured by one rolling wheel 20, one horizontal support shaft 21 and one hanger 24, the runner 2 is simpler than the conventional runner 2.
It is possible to reduce the number of parts, simplify the structure, facilitate manufacturing and assembling, and reduce the cost.

On the other hand, as shown in FIG. 6, the curtain rail 1 may be formed in a substantially channel-shaped cross section in two rows. With such a configuration, the section modulus and bending stress are larger than those of the curtain rail 1 formed in a series of substantially channel-shaped cross sections, and thus the rigidity is further increased and the curtain 3 having a large thickness and a large weight is provided. You can open and close the suspension smoothly without any problems.

In the above embodiment, both the stop member 5 on the side of the runner 2 and the stop member 4 on the side of the curtain 3 are made of adhesive cloth for explanation, but other stopping means may be appropriately selected and used. Good.

[0016]

As described above, according to the first aspect of the invention, since the web is oriented vertically, the section modulus and bending stress increase, and high rigidity is ensured even when the wall thickness is reduced. it can. This can reduce the cost of the curtain rail. Also, in the case of a parallel double-track structure,
For example, since the amount of protrusion to the indoor side can be suppressed to a small amount, it is possible to avoid the curtain rail from interfering with each other when installing furniture or furniture. Moreover, the runner can be simply constructed by the three parts of the rolling wheel, the horizontal support shaft and the hanger. Therefore, compared to conventional runners,
The number of parts can be reduced, the structure can be simplified, manufacturing and assembling can be facilitated, and the cost can be reduced. According to the invention of claim 2, since the section modulus and the bending stress are larger than those of the curtain rail formed in a series of substantially channel-shaped cross sections, it is possible to smoothly suspend and open a thick and heavy curtain without any trouble. Can be done.
