It is inserted in between so that the traveling can be performed without swinging the hanging door body 3.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

Runners 2, 2 are attached to the front and rear portions of the upper end of the suspension door main body 3, and these runners 2 are inserted into the upper rail 1 having a U-shaped cross section provided with traveling receiving pieces 10, 10 so as to be able to travel freely. 3
Are held on the upper rail 1 so as to be able to run freely. Guide pins 4 are provided on the floor surface 11 at appropriate intervals so as to be able to protrude and retreat by magnetic force. A running groove 5 is provided at the lower end of the suspension door body 3.
Are formed over the entire length. The running groove 5 may be formed of, for example, a magnetic material such as an iron plate. Alternatively, the running groove 5 may be formed by inserting and fixing a substantially U-shaped cross section. Attraction portions 7 are provided at front and rear portions of the traveling groove 5 of the suspension door body 3. Thus, when the suspension door body 3 travels in the closing direction,
The guide pin 4 sunk under the floor is magnetized by the attraction magnet 7 and pulled up, and the guide pin 4 protrudes into the running groove 5 on the lower end face of the suspension door body 3, and the running state is maintained while the protruding state is maintained. Guides are provided.

The guide pin 4 is inserted into a cylindrical portion 12 embedded under the floor so as to be able to move up and down, and a magnet 6 is attached to the tip of the guide pin 4. A sliding ridge 13 is formed on the guide pin 4 so that the guide pin 4 can slide up and down with little resistance to the cylindrical portion 12.

The attracting magnet 7 whose magnetic pole is different from that of the magnet 6 provided at the tip of the guide pin 4 is made substantially horizontal, and the other pole of the attracting magnet 7 is the same in polarity as the magnet 6 on the guide pin 4 side. In addition, a repulsion magnet portion 9 for retreating the guide pin 4 below the floor surface is formed. On both sides of the attraction magnet 7, an inclined guide 8 made of a magnetic material such as an iron plate is formed.

When the suspension door body 3 travels in the closing direction, the guide pins 4 that unexpectedly protrude from the floor surface at the inclined guide portion 8 are provided.
Is pressed down below the floor surface, and the guide pin 4 projecting from the floor surface is further pushed in by the repulsion magnet 9 utilizing the repulsion, and the guide pin 4 is pulled by the suction magnet 7 when the suspension door body 3 travels further. 4 is magnetized and pulled up via the magnet 6 at the upper end thereof, and the magnet 6 is attached to the inclined guide portion 8a formed of a magnetic material.
Is magnetically attached, the guide pin 4 is further raised, and the suspension door body 3
, And the suspension door body 3 is guided and traveled by the guide pins 4. When the guide pin 4 reaches the end of the running groove 5, the guide pin 4 is pushed down by the inclined guide 8a, and finally the guide pin 4 is completely pushed down by the repulsion magnet 9 into the inside of the cylindrical portion 12. It is something to keep.

The tubular portion 12 is buried below the floor surface by being prevented from coming off via a locking projection 18 on the outer periphery. Flange around upper end of cylinder 12
19 is formed, and the insertion depth of the cylindrical portion 12 is determined by bringing the flange 19 into contact with the floor surface 11. A cylindrical intermediate spacer 16 that is sufficiently shorter than the cylindrical portion 12 is inserted into the inside of the cylindrical portion 12 at a large-diameter portion 23 having an increased inner diameter, so that the intermediate spacer 16 can be freely inserted and removed. The inside diameters are almost equal. The guide pin 4 is inserted into the intermediate spacer 16 and the cylindrical portion 12 so as to be able to move up and down. And the intermediate spacer
At the upper end of 16, a flange 17 for removal is extended around the periphery,
This flange 17 is overlaid on the flange 19 of the tubular portion 12. Further, a pin 20 is fixed to the guide pin 4, and the pin 20 is inserted into a long hole 21 formed in the intermediate spacer 16. Therefore, when dust is clogged between the cylindrical portion 12 and the guide pin 4, a plate-shaped jig 22 is inserted between the flange 17 of the intermediate spacer 16 and the flange 19 of the cylindrical portion 12 and lifted.
The intermediate spacer 16 is pulled out upward. In such a case, a long hole
The lower end of the abutment 21 comes into contact with the pin 20 so that the guide pin 4 can also be pulled out of the cylindrical portion 12.

A magnet 26 is attached to the lower end of the guide pin 4 and a holding magnet 27 is also embedded in the peripheral side wall of the intermediate spacer 16, so that the guide pin 4 is magnetically attached to the side of the hanging door body 3 and pulled up most. In this state, the magnet 26 at the lower end of the guide pin 4 is magnetically attached to the holding magnet 27 so that the guide pin 4 can be held in the pulled up state. By holding the raised state, the guide pin 4 is inserted deeply into the running groove 5 of the suspension door body 3 to stabilize the guide function.

A locking claw 29 is provided at the lower end of the intermediate spacer 16 so as to be elastically displaceable. The locking claw 29 is detachably engaged with the concave portion 30 of the cylindrical portion 12, whereby the intermediate spacer 16 is unexpectedly raised. I don't want to do that. The locking claws 29 may not be provided.

In the embodiment, the intermediate spacer 16 and the guide pin 4 are connected via the pin 20 and the elongated hole 21, but the intermediate spacer 16 and the guide pin 4 need not be connected.

An inclined magnet portion 8 is formed outside the attraction magnet 7 so as to abut on and push the guide pin 4 projecting from the floor surface 11.

As shown in FIG. 5, the upper end of the hanging door body 3 can be cut with a saw 15 or the like in a certain range, and the height of the hanging door body 3 is changed and adjusted to cope with the height of the built-in place. You can do it. A cap 9 made of a synthetic resin is externally fitted to the upper end of the hanging door body 3 thus cut, and the cut portion is closed.

In the runner 2, runner rollers 2 a are rotatably mounted on both ends of two horizontal shafts 16, respectively, and such runner rollers 2 a are rotatable on a runner receiving piece 1 a formed on the upper rail 1. It is mounted on. On the upper surface of a cap 9 having a substantially inverted U-shaped cross section that covers the upper end surface of the hanging door body 3, a long running guide 14 is provided slidably inserted between the runner receiving pieces 1a, 1a of the runner 2.

In this manner, the long travel guide 14 of the cap 9 is inserted between the runner receiving pieces 1a, 1a of the upper rail 1 on the side of the suspension door main body 3 so that traveling can be performed without swinging the suspension door main body 3. .
