BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for smoothly and quietly running and opening a sliding door.

[0002]

2. Description of the Related Art A conventional running device for a sliding door has a lip channel-shaped hanger rail installed above,
The hanging door carriage mounted above the sliding door body was fitted so that the wheels of the hanging door carriage could run on the lip portion.

However, since the hanger rail and the hanging door wheel of the conventional device are both made of metal, noise is generated during running, and depending on the running state, the hanging door wheel contacts the inner wall of the hanger rail. There was a possibility that the vehicle would not run normally.

Moreover, the conventional traveling device for the sliding door is
Since the sliding door main body was hung on the hanging door wheel by the bolt-shaped shaft body, an extremely large gap was created between the hanger rail and the sliding door main body, and it was impossible to prevent the circulation of the atmosphere.

In order to deal with such various inconveniences, tires made of rubber or the like are fitted to the hanging door car for soundproofing,
It was found that the inner edge of the lip of the hanger rail was bent upward to control the swing of the hanging door car to prevent contact with the inner wall, but any of these methods required labor to manufacture. However, in spite of the high cost, it is not possible to expect a sufficient effect, and the atmospheric circulation is not improved at all.

[0006]

A problem to be solved is that it is difficult for a conventional traveling device for a sliding door to generate noise during traveling and to obtain a normal traveling state.

DISCLOSURE OF THE INVENTION The present invention is directed to a long rail body having a lip channel shape in cross section, which has a gap groove in the lower center thereof, and an upper surface of a lip portion of the rail body. Toward the inclined surface, an isoelectric body such as a ferrite magnet fixed in series along the longitudinal direction on both inclined surfaces, and an inclined lower surface facing each magnetic body, a magnetic body that repels the magnetic body. Is a fixed piece, a connecting piece that is provided below the protruding piece and is inserted into the gap groove, and a suspending body that is provided with the connecting piece and is attached to the upper end of the sliding door body.

Further, it is preferable that the connecting piece is provided at a central portion in the width direction of the sliding door body. Further, the hanging body may be attached in series to the entire length of the upper end portion of the sliding door body.

[0009]

The rail body is attached to a dwelling or a ceiling with a gap groove arranged downward, and a magnetic body such as a ferrite magnet is fixed in series along the longitudinal direction of the inclined surface of the lip. However, the long magnetic body is fixed in that state, and the short magnetic body is fixed in series with the same poles of a large number of magnetic bodies being sequentially abutted.

On the other hand, at the upper end of the sliding door body, a hanging body having a connecting piece inserted into the gap groove is attached.
An overhanging piece corresponding to the inclined surface of the lip portion is provided above the connecting piece, and a magnetic body that repels the magnetic body is fixed to the inclined lower surface, and the hanging body is the upper end of the sliding door body. With a proper interval to the overhanging piece, the magnetic body is also attached to the overhanging piece at an appropriate interval according to the size and weight of the sliding door body, or fixed to the lip part. Similarly, it is fixed in series over the entire length.

In the sliding door body, the connecting piece is inserted into the gap groove,
The overhanging piece is inserted into the rail body and hung on the rail body.The magnetic body fixed to the inclined lower surface of the overhanging piece repels the magnetic body of the lip part, and the sliding door body resists the weight. Float and run along the rail body in this levitated state.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 is a long rail body having a cross-sectional lip channel shape with a gap groove 2 provided in the lower center, and an upper surface of a lip portion 3 is An inclined surface 4 is formed which gradually descends toward the inner side in the width direction. Reference numeral 5 denotes a magnetic body made of, for example, a ferrite magnet or the like, which is fixed in series along the longitudinal direction of both inclined surfaces 4, and a large number of short magnetic bodies 5 are sequentially arranged with the same poles butted to each other and provided on the lip portion 3. It is held by the hook-shaped piece 6.

Reference numeral 7 denotes a suspension body attached to the upper end portion of the sliding door body 8, and the suspension body 7 has a connecting piece 9 inserted into the gap groove 2 and erected at the central portion of the sliding door body 8 in the width direction. Above the connecting piece 9, there is formed an overhanging piece 11 having an inclined lower surface 10 facing the inclined surface 4 of the lip portion 3. 1
Reference numeral 2 denotes the magnetic material 5 on each of the inclined lower surfaces 10 of the overhanging pieces 11.
The magnetic body fixed to the magnetic body 5 is arranged so as to repel the magnetic body 5, and is held by the hook-shaped piece 13 provided on the overhanging piece 11. Reference numeral 14 is a ceiling or the like to which the rail body 1 is attached.

In the embodiment shown in the drawings, the rail body 1 and the overhanging piece 1 are provided.
Although a pair of magnetic bodies 5 and 12 are fixed relative to 1, depending on conditions such as the weight of the sliding door body 8,
It is also conceivable to dispose and fix the magnetic bodies so as to form two pairs in the vertical direction of the rail body 1 and the overhanging piece 11.

Further, although the hanging body 7 is of a type that straddles the upper end of the sliding door body 8 and the connecting piece 9 is erected directly on the central portion of the hanging body 7 in the width direction, this is not always the case. However, it is sufficient that the connecting piece 9 is present in the central portion of the sliding door body 8 in the width direction.

Further, the sliding door body 8 is provided with a guide below like a conventional hanging door, and is fitted to a guide rail embedded in a floor or the like to guide the sliding door body 8 so that unexpected swing can be prevented. Of course.

[0017]

Since the present invention is constructed as described above, the sliding door main body can be suspended without contacting the rail body, and running in this state has no contact portion, No noise is generated and extremely quiet running can be obtained.

Moreover, since the magnetic body for floating the sliding door main body is fixed to the inclined surface of the lip portion and the inclined lower surface of the overhanging piece so as to descend inward in the width direction, the sliding door main body is self-weighted. As a result, the rail body is always positioned at the center in the width direction, and when the sliding door body travels, a normal traveling state can be secured without the protruding piece or the like coming into contact with the inner wall of the rail body.

Further, since the connecting piece is provided at the central portion of the sliding door body in the width direction, the sliding door body can be always hung on the rail body in a well-balanced manner.

Further, by mounting the hanging body in series over the entire length of the upper end portion of the sliding door body, the gap formed between the rail body and the sliding door body is closed by the connecting piece, and the circulation of the atmosphere is minimized. It can be stopped.
