Conventionally, two magnets 7 are provided by making the other pole of the attraction magnet 7 the same pole as the magnet 6 on the guide pin 4 side to form the repulsion magnet portion 9 for retracting the guide pin 4 below the floor. , 7a can be reduced to one, and the structure is simplified. At one end side, the attraction magnet 7 has different poles from the lower end to the upper end, and at the other end of the attraction magnet 7 also from the lower end. It has a different polarity up to the upper end, and therefore, the guide pin 4 is raised by the attraction magnet 7 via the magnet 6 of the guide pin 4,
In guiding this to the running groove 5, the magnet 6 for guiding does not repel the magnet 6 of the guide pin 4 at the time of guiding,
The guide pin 4 can be smoothly guided to the running groove 5, and the repulsion magnet portion 9 which is the other magnetic pole portion of the attraction magnet 7 is also magnetically attached to the magnet 6 of the guide pin 4. In this case, the repulsive action of the guide pin 4 at such a position can be performed in a predetermined manner, and the movement of the guide pin 4 can be correctly performed without error.

Embodiment An embodiment of the present invention will be described in detail below with reference to the drawings.

The runners 2, 2 are attached to the front and rear portions of the upper end of the hanging door body 3, and these runners 2 are movably inserted into the upper rail 1 having a U-shaped cross section provided with the running receiving pieces 10, 10, and the running door body is 3 is held on the upper rail 1 so as to run freely. Guide pins 4 are provided on the floor surface 11 at appropriate intervals so as to project and retract by magnetic force. A running groove 5 is formed over the entire length at the lower end of the hanging door body 3. The running groove 5 is formed of a magnetic material such as an iron plate. At the front and rear ends of the running groove 3 of the hanging door body 3, suction magnets 7 are provided. Then, when the hanging door body 3 travels in the closing direction, the guide pin 4 sinking under the floor is magnetically attracted by the attraction magnet 7 and pulled up, and the guide pin 4 travels on the lower end surface of the hanging door body 3. It is adapted to rush into the groove 5 and to be able to guide the running while the rushed state is maintained. Then, when the hanging door body 3 is running, the guide pin 4 can be sunk below the floor surface by the repulsive force due to the magnetic force by the repulsive magnet portion 9 on the rear end side.

The guide pin 4 is vertically inserted into an outer cylinder 12 embedded under the floor, and a magnet 6 is attached to the tip of the guide pin 4. A sliding protrusion 13 is formed on the guide pin 4,
It can slide up and down with less resistance than 12.
The design of the guide pin 4 and the structure of the outer cylinder 12 that holds the guide pin 4 in a vertically movable manner can be changed in various ways. Guide pin 4
An attracting magnet 7 having a magnetic pole different from that of the magnet 6 provided at the tip of the above is provided at the tip of the running groove 5 on the hanging door body 3 side. The suction magnet 7 is substantially horizontal,
The other pole of the magnet 7 for attraction is made the same pole as the magnet 6 on the guide pin 4 side to form a repulsion magnet portion 9 for retracting the guide pin 4 below the floor. On both sides of the attraction magnet 7 and the repulsive magnetic force portion 9, tilt guides 8 made of a magnetic material such as an iron plate are formed.

As described above, the attraction magnet 7 having a magnetic pole different from that of the magnet 6 provided at the tip of the guide pin 4 is provided on the hanging door body 3 side, and the attraction magnet 7 is made substantially horizontal so that the attraction magnet 7 is provided. By making the other pole of 7 the same pole as the magnet 6 on the side of the guide pin 4 and forming the repulsion magnet portion 9 that retreats the guide pin 4 below the floor surface, two magnets 7, 7a are conventionally used. It is possible to reduce the required number to one and simplify the configuration. The attracting magnet 7 has different polarities from one end to the other end from the lower end to the upper end, and the repulsive magnet portion 9 at the other end of the attracting magnet 7 also has different polarity from the lower end to the upper end. Therefore, in order to raise the guide pin 4 through the magnet 6 of the guide pin 4 by the attraction magnet 7 and guide it to the running groove 5 through the inclined guide portion 8, the attraction magnet 7 is guided at the time of the guidance. The magnet 6 of the guide pin 4 is not repelled, and the guide pin 4 is smoothly guided to the running groove 5. Also, the other magnetic pole portion of the attraction magnet 7, that is, the repulsion magnet portion 9 is not magnetically attached to the magnet 6 of the guide pin 4. In this way, the repulsive action of the guide pin 4 can be performed in a predetermined manner, and the movement of the guide pin 4 can be correctly performed without error. A sliding protrusion 13 is formed on the outer surface of the guide pin 4 so that it can be lightly moved up and down with respect to the outer cylinder 12.

[Advantages of the Invention] In summary, according to the present invention, a suction magnet having a magnetic pole different from that of the magnet provided at the tip of the guide pin is provided on the main body of the hanging door, and the suction magnet is made substantially horizontal to attract. Since the other pole of the magnet for use becomes the same pole as the magnet on the side of the guide pin to form the repulsive magnet portion that retracts the guide pin below the floor,
Conventionally, two magnets were required, but the number of magnets can be reduced to one, and the structure can be simplified. At one end, the attraction magnet has different polarities from the lower end to the upper end, and also at the other end of the attraction magnet. Since the polarity is different from the lower end to the upper end, the guide pin is raised by the magnet for suction through the magnet of the guide pin and is guided to the running groove. The guide pin can be smoothly guided to the running groove without repulsing the magnet, and the other magnetic pole portion of the attraction magnet serves as the repulsion magnet portion. There is no magnetic sticking to the magnet, and the repulsive action of the guide pin at such a place can be performed as specified,
There is an advantage that the movement of the guide pin can be correctly performed without error.
