BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a partitioning device which guides a suspension door body by projecting a guide pin provided on a floor surface so as to be able to protrude and retreat from a floor surface by a magnetic force. The present invention relates to a technique for improving the degree of sealing between a hanging door body and a vertical frame when the hanging door body is closed.

[0002]

2. Description of the Related Art Heretofore, there has been proposed a partitioning device which guides a suspension door body by projecting a guide pin provided on a floor surface so as to be able to protrude and retract from the floor surface by magnetic force.

[0003]

In such a construction, however, a guide pin protruding from the floor surface by suction is introduced into a sliding contact groove at the lower end of the suspension door body to guide the sliding contact. In order to guide the vehicle by introducing the guide pin into the sliding contact groove as described above, a clearance for sliding movement is required between the guide pin and the sliding contact groove, and a certain amount of rolling occurs. Then, when closing the suspension door body in contact with the vertical frame, horizontal swing occurs, and there is a problem that it is difficult to maintain the closed state in a good condition.

The present invention is intended to solve such a problem, and it is effective to employ a structure in which a guide pin is attracted and repelled by a magnet formed on a side of a suspension door to project and retract the guide pin from a floor surface. It is an object of the present invention to provide a partitioning device which can improve airtightness when the hanging door body is closed by bringing the hanging door body into contact with a vertical frame.

[0005]

According to the present invention, the suspension door body 3 is erected on the upper rail 1 so that it can run freely, and a large number of guide pins 4 are arranged on the floor 11 in a line and protrude from the floor 11. A magnet 6 is provided at the upper end of the guide pin 4 so as to be freely arranged, and the suspension door main body 3 has an attraction magnet 7 having a different magnetic pole from the magnet 6 on the guide pin 4 side, and an attraction magnet 7. And a return groove 9 having the same polarity as the magnet 6 on the guide pin 4 side and a sliding contact groove 5 for sliding contact with the guide pin 2 sucked and pulled up by the suction device. Magnet 7
Alternatively, the return magnet 9 is disposed at the side end of the hanging door main body 3, and thus faces the attraction magnet 7 or the returning magnet 9 provided at the side end of the hanging door main body 3. The magnetic member 17 is provided on the vertical frame 16 with which the side end of the third member 3 contacts.

[0006]

As described above, the suspension door main body 3 is built on the upper rail 1 so as to be able to run freely, and a large number of guide pins 4 are arranged on the floor surface 11 in a line and protrude from the floor surface 11 so as to be retractable. A magnet 6 is provided at the upper end of the guide pin 4, and the suspension door body 3 is attracted and pulled up by the attraction magnet 7 having a different magnetic pole from the magnet 6 at the guide pin 4 side and the attraction magnet 7. And a return magnet 9 having the same polarity as the magnet 6 on the guide pin 4 side. The attraction magnet 7 or the return magnet 9
Is disposed at the side end of the hanging door body 3, and is opposed to the attraction magnet 7 or the returning magnet 9 provided at the side end of the hanging door body 3 as described above. Vertical frame 1 against which
6 is provided with a magnetic body 17 so as to effectively use the attracting magnet 7 that attracts the guide pin 4 and projects from the floor 11 or the return magnet 9 that pushes the guide pin 4 below the floor 11. By magnetizing such a magnet to the magnetic body 17 provided on the vertical frame 16, airtightness is ensured when the suspension door body 3 is closed. It is an oppositely protruding one.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
2 are attached, and these runners 2
The suspension door main body 3 is movably inserted into the upper rail 1 having a U-shaped cross-section and provided with a zero. Guide pins 4 are provided on the floor 11 at appropriate intervals so as to be able to protrude and retreat by magnetic force. And the hanging door body 3
A sliding contact groove portion 5 is formed at the lower end of the entire length. The sliding contact groove 5 may be formed of a magnetic material such as an iron plate. Attraction portions 7 are provided in front and rear portions of the sliding contact running groove portion 5 of the suspension door body 3. When the suspension door body 3 travels in the closing direction, the magnet 6 at the upper end of the guide pin 4 sunk below the floor is magnetized by the attraction magnet 7 and pulled up. The lower end surface of the sliding contact groove 5 is slid into the sliding contact groove portion 5 so that the slidable state is maintained so that the traveling guide can be performed. The guide pin 4 is inserted into the outer cylinder 12 embedded below 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.

The magnet 6 provided at the tip of the guide pin 4 has the other pole of the attracting magnet 7 having a different magnetic pole and the same polarity as the magnet 6 on the guide pin 4 side, and the guide pin 4 is placed on the floor surface. It is formed as a repulsion return magnet 9 for retreating downward. Incidentally, the attracting magnet 7 is made substantially horizontal, and the other pole of the attracting magnet 7 is used as a return magnet 9. When the suspension door body 3 travels in the closing direction, the guide pin 4 is moved by the attraction magnet 7.
Is magnetically attracted through the magnet 6 at the upper end thereof, pulled up, guided to the sliding contact running groove 5 of the hanging door main body 3, and the hanging door main body 3 is guided and traveled by the guide pins 4.
When the guide pin 4 reaches the end of the sliding contact groove 5, the guide pin 4 is pushed down into the outer cylinder 12 by the return magnet 9 and returned. A ridge 13 is formed on the outer peripheral portion of the guide pin 4 so that the guide pin 4 can be raised and lowered lightly with respect to the outer cylinder 12.

The return magnet 9 is disposed close to the side end of the hanging door body 3, and the vertical frame 16, which is brought into contact with the hanging door body 3 when closed, is opposed to the returning magnet 9. Pole magnet 17
a is attached. The magnet 17a may be replaced with a magnetized body 17b such as an iron piece. In other words, any magnet may be used as long as the return magnet 9 is magnetized.
Collectively. Then, the attraction magnet 7 may be arranged at the side end of the hanging door body 3.

[0010] As shown in FIG.
Are formed so as to prevent the hanging door main body 3 that has entered the concave groove 18 from rolling sideways.
In addition, the state where the guide pin 4 is sucked and pulled up is held by a magnetic plate such as an iron plate constituting the sliding contact running groove 5. For example, the outer cylinder 1 through which the guide pin 4 is inserted and held.
2, a projecting and holding means using a permanent magnet may be formed.

[0011]

[Effect of the Invention] As described above, in the present invention, the hanging door body is erected on the upper rail so that it can run freely, and a large number of guide pins are arranged on the floor so as to be able to protrude and retreat from the floor. , A magnet is provided at the upper end of the guide pin, and the suspension door body has an attraction magnet having a different magnetic pole from the guide pin side magnet,
A partitioning device including a sliding contact running groove portion that slides on a guide pin that is attracted and pulled up by an attraction magnet, and a return magnet having the same polarity as the guide pin side magnet. A return magnet is disposed at the side end of the hanging door body, and the side end of the hanging door body is opposed to the attraction magnet or the returning magnet provided at the side end of the hanging door body. Since a magnetic material is provided on the vertical frame in contact with the magnet, such a magnet is effectively used by using a magnet for suction that attracts the guide pin and protrudes from the floor surface or a magnet for returning the guide pin back below the floor surface. By magnetically attaching to the magnetic material provided in the vertical frame, there is an advantage that airtightness can be secured when the suspension door body is closed.
