[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rail structure for suspending a sliding door.

[0002]

2. Description of the Related Art FIG. 2 shows a rail structure which has been frequently used, and a sliding door (b) is hung on the rail (a). A roller (c) is attached to the upper end of the sliding door (b),
The sliding door (b) is opened and closed by the roller (c) rolling on the traveling piece (d) provided in (b). The rail (a) is a long material that forms a gate shape and opens downward.
Is formed to extend inward from both side pieces. A guide piece (e) is installed above the traveling piece (d) to guide the roller (c) rolling on the traveling piece (d) so that the roller (c) does not come off the traveling piece (d). .

By the way, a rail having a gate-shaped cross section as described above
When the sliding door (b) is hung on (a), it is not possible to hang the roller (c) on the traveling piece (d) from the side because the side pieces are located on both sides. Suspend at a specified position while being put in. That is, the roller (c) is hung on the traveling piece (d), and the guide piece (e) does not come off from the traveling piece (d).
Because it is restrained by, the roller (c) runs on the traveling piece (d).
There must be a space to hang it around, so the guide piece (e) is partially cut out. Therefore, when suspending the sliding door (b) from the inside,
Must be hung on the running piece (d) at the above notch,
However, since the notch cannot be seen from the outside, it is not easy to align the two.

As described above, when the gate-shaped cross-section rail is used, the work of suspending the sliding door (b) is troublesome, and therefore, there is also a rail which can be hung from the outside as shown in FIG. In this rail structure, the roller (c) is hung from the side on the traveling piece (d),
In that state, attach the guide member (f) to prevent the detachment. Unlike the conventional example, the guide member (f) is attached to the sliding door (b) without being provided on the rail (a), and the traveling piece (d) is connected to the roller (c) along the lower side of the traveling piece (d). It moves so as to hold it with the guide member (f). However, in the rail structure with side openings, the roller (C) is exposed to the outside and the external appearance is impaired, so the cover (G) is attached. Therefore, in the rail structure, in addition to the rail, there is a problem in production and installation work in that the cover (g) and the guide member (f) must be prepared and attached, and the guide member (f) must be installed. Since there is a space problem in mounting, the cover (g) has to be extended downward, and the sliding door height is reduced accordingly. On the other hand, as the distance between the sliding door (b) and the roller (c) increases, the opening and closing force of the sliding door (b) creates a moment, which hinders smooth opening and closing.

[0005]

As described above, the conventional hanging rails for sliding doors have the above-mentioned problems. The problems to be solved by the present invention are these problems, and it is possible to provide a suspension rail in which a rail cover having a roller disengagement prevention function is assembled in addition to easy suspension work on the rail.

[0006]

The suspension rail of the present invention is a long member having an opening on the side so that a sliding door can be hung from the side, and a traveling piece is formed at a predetermined position. And reverse L
A rail cover made of a long material with a V-shaped cross section is attached so that the opening on the side of the rail body is closed. Here, the attachment of the rail cover is performed after the sliding door is hung, and the upper piece of the rail cover is arranged between the rail body and the roller of the sliding door that is hung on the running piece to exhibit a floating prevention function of the roller. . The rail cover may be attached not only to both sides of the rail body but also to one side, and the use of the sliding door is not limited. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

[0007]

1 is an embodiment showing a suspension rail structure of the present invention, which suspension rail is composed of a rail body 1 and a rail cover 2. The suspension rail is a rail symmetrical with respect to the neutral axis MM, but the rail cover 2 is attached to the right side and the sliding door 3 is suspended.
The rail body 1 extends the arm 4 horizontally from the lower end thereof,
Has a traveling piece 5 at its tip, and a screw 7 is screwed onto the upper piece 6 to fix the rail to the crosspiece 8. An upper surface 9 of the running piece 5 has a smooth convex curved surface, and a roller 11 having a concave groove 10 that fits into the upper surface 9 is mounted on the running piece 5. An L-shaped hanger 12 is attached to the side of the roller 11 to suspend the sliding door 3. Therefore, as the roller 11 rolls along the traveling piece 5, the sliding door 3 opens and closes.

A rail cover 2 is attached to the side of the rail body 1 to cover the roller 11 and the hanger 12. The rail cover 2 is a long member having a substantially inverted L-shaped cross section, has a side piece 13 and an upper piece 14, and has upper pieces 6 on the upper pieces 6 of the rail body 1 which project downward. 14
Are brought into contact with each other for positioning, and screws 16 are screwed and screwed. By the way, the rail cover 2 functions as a cover by the side piece 13, and the upper piece 14 performs a function of stably fixing the rail cover 2 to the rail body 1 and a function of preventing the roller 11 from floating. Since the rail structure of the present invention is open at the side, the sliding door 3 can be easily hung from the outside, so that the distance between the running piece 5 and the hitting piece 15 that the roller 11 can pass through. Have That is, the contact piece 15 runs on the roller 11 without causing any obstacle.
You can hang it on. However, the rail cover 2
If the upper piece 14 is arranged between the roller 11 and the contact piece 15 by attaching the roller 11,
It is not possible to come into contact with and float on the roller, and therefore
The separation of 1 from the traveling piece 5 is prevented. As described above, the suspension rail structure of the present invention comprises a combination of a rail body having an opening on the side and a rail cover having a substantially inverted L-shaped cross section, and the upper piece of the rail cover is used as a traveling piece. It is arranged above the suspended roller and the side piece covers the opening, so that the following effects can be obtained.

[0009]

EFFECTS OF THE INVENTION Since the suspension rail of the present invention has a structure in which the sides are open, the hanging work of the sliding door is extremely easy. Then, a rail cover is attached to cover the rollers, the hangings, and the like of the sliding door suspended on the running piece. The rail cover is a long material having a substantially inverted L-shaped cross section, and the upper piece thereof is It is arranged above the suspended roller to prevent the roller from floating. That is, the rail cover has the function of covering the side opening of the rail body and the function of preventing the roller from floating, and the manufacturing and mounting work is reduced as compared with the conventional type in which separate members are mounted. On the other hand, since the rail cover is fixed by screwing it onto the upper piece, the fixing is stable, and the screw is not exposed to the outside so that the appearance is not damaged.
