BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a linear motor type curtain opening / closing apparatus, and more particularly to a ring runner type linear motor type curtain opening / closing apparatus.

[0002]

2. Description of the Related Art Currently, linear motors are being used for curtain rails for electrically opening and closing curtains in houses, office buildings, hotels and the like. The structure of this linear motor will be described with reference to FIG.

FIG. 6 is a perspective view showing components of a linear motor. The linear motor includes stators 40A and 40B housed in the outer rail 220, and a mover 5 housed in the outer rail 220 slidably in the longitudinal direction.
0 and the strip-shaped overhead wire 30 accommodated in the upper wall of the outer rail 220. Outer rail 2
20 is formed in a substantially inverted U-shaped cross section. Inside the outer rail 220, the stators 40A and 40B including the permanent magnet 42 and the yoke 44 are housed along the longitudinal direction thereof. In addition, the mover 50 includes three substantially cylindrical armatures 5.
Outer rail 220 with 2A, 52B and 52C
It is slidably disposed inside.

A leading runner 74 is connected to the lower end of the mover 50 via a connecting fitting (not shown). The lower end of the top runner 74 has an opening 220h in the outer rail 220.
Is projected downward from. The wheel 74a attached to the leading runner 74 is configured to roll on horizontal pieces 220g and 220g formed at the lower end of the outer rail 220. Inside the outer rail 220,
A runner 76 for suspending a curtain (not shown) is arranged together with the leading runner 74.

In this linear motor type curtain rail, the rail (outer rail 220) is exposed, and the curtain hook hooking portions of the runners 74 and 76 are exposed from the lower opening 220h. This curtain rail is designed so that the upper rail of the curtain (not shown) is attached to a position higher than the upper edge of the outer rail 220 to make the outer rail 220 invisible.

[0006]

At present, a manual curtain rail is designed by arranging an annular runner called a ring runner on the outer circumference of the rail and by actively showing the ring runner together with the curtain rail. There is an accent above. Here, when a so-called ring runner type curtain runner is to be driven by a rotary motor, it is necessary to dispose a large rotary motor on the side of the rail, and the handling of the wire for pulling the ring runner within the rail is complicated. It was expected that the curtain could not be opened and closed manually.

On the other hand, when a ring runner type curtain runner is to be driven by a linear motor as shown in FIG. 6, the ring runner 80 connected to the mover 50 starts traveling as shown in FIG. Sometimes it becomes slanted,
It was assumed that the outer rail 220 could not be driven smoothly and smoothly.

The linear motor of the present invention has been made in order to solve the above-mentioned problems, and an object thereof is to provide a linear motor type curtain opening / closing device that allows a ring runner to travel smoothly. is there.

[0009]

In order to achieve the above object, in a linear motor type curtain opening / closing device of the present invention, a rail main body incorporating a stator, a mover traveling inside the rail main body, and A plurality of annular runners capable of suspending a curtain that is movably fitted along the outer periphery of the rail body along the rail body, and of the plurality of annular runners, the leading annular runner is fixed to the mover. This is a technical feature.

[0010]

In the linear motor type curtain opening / closing device of the present invention, since the leading annular runner is fixed to the mover, the leading annular runner that moves with the moving element moves diagonally when the mover travels. And the rail body will not get caught.

[0011]

Also in the linear motor of the second embodiment, since the ring runner 180 is fixed to the mover 50, the ring runner 180 does not incline when the curtain is opened and closed, and the ring runner 180 does not get caught in the outer rail 120. Therefore, the ring runner 180 smoothly moves to the outer rail 120.
You can slide on it to open and close the curtain.

In the first embodiment, an example using the cylindrical outer rail 20 and the annular ring runner 80 is used, and in the second embodiment, the prismatic outer rail 120 and the rectangular ring are used. Although the runner 180 is used as an example, the present invention may use outer rails of various shapes such as a triangular shape, a pentagonal shape, a hexagonal shape, and ring runners of various shapes that surround the outer circumference of the outer rails. It is possible. In the first and second embodiments,
Although the magnet movable type linear motor has been illustrated, it goes without saying that the present invention can also be applied to a coil movable type linear motor.
