[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plurality of suspension door bodies which are suspended and held via runners on respective upper rails which are juxtaposed in parallel, and which can be retracted by a magnetic force on a floor surface. The guide pins provided on the bottom of the hanging door body are inserted into the running grooves formed in the lower end surface of the hanging door body in a protruding state to perform the running guide so that the plurality of hanging door bodies are partially overlapped in the thickness direction. More specifically, the present invention relates to a guide device for a suspension door that closes an opening by using a magnetic force to prevent the guide pin from protruding above the floor surface from being provided with a sufficient guide function while avoiding an unnecessary increase in the number of guide pins. It concerns technology.

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 running groove 5 is formed at the lower end of the body. Running groove 5
May be formed of a magnetic material such as an iron plate. Attraction portions 7 are provided at front and rear portions of the traveling groove 5 of the suspension door body 3. When the suspension door body 3 travels in the closing direction, the guide pin 4 sunk under the floor is magnetically attracted by the attraction magnet 7 and pulled up, and the guide pin 4 travels on the lower end face of the suspension door body 3. The vehicle enters the groove 5 so that the traveling state can be maintained and the traveling guide can be performed.

The guide pin 4 is an outer cylinder 1 embedded below the floor.
The magnet 6 is attached to the tip of the guide pin 4 so as to be vertically movable with respect to 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 retreated below the floor surface. The magnet portion 9 for repulsion is made. 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 which unexpectedly protrude from the floor surface by the inclined guide portion 8 are pressed down below the floor surface, and further the guide pins 4 which protrude from the floor surface. The pin 4 is guided by the repulsion magnet 7 into the guide pin 4
The magnet 6 is magnetically attached to the inclined guide portion 8 made of a magnetic material, and the guide pin 4 is further raised. , 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 portion 8, and finally the guide pin 4 is completely inserted into the outer cylinder 12 by the repulsion magnet 9. It is something to keep down.

In such a case, when there is a possibility that dust may enter between the guide pin 4 and the outer cylinder 12 and hinder the movement of the guide pin 4, the guide pin 4 is easily pulled out and enters. Can be easily removed for maintenance. Hereinafter, the configuration will be described in detail. An outer cylinder 12 is buried under the floor so as to be prevented from coming off via a locking projection 18 on the outer periphery. Flange 19 is provided on the upper peripheral portion of outer cylinder 12.
Is formed, and the insertion depth of the outer cylinder 12 is determined by bringing the flange 19 into contact with the floor surface 11. Inside the outer cylinder 12, a cylindrical intermediate spacer 16 that is sufficiently shorter than the outer cylinder 12 is inserted into a large-diameter portion 23 having an increased inner diameter so as to be freely inserted into and removed from the outer cylinder 12. The inside diameters are almost equal. The guide pin 4 is inserted into the intermediate spacer 16 and the outer cylinder 12 so as to be able to move up and down. At the upper end of the intermediate spacer 16, a flange 17 for pulling out extends to the peripheral portion, and the flange 17 is overlapped with the flange 19 of the outer cylinder 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. If dust is clogged between the outer cylinder 12 and the guide pin 4, the plate-shaped jig 22 is moved to the flange 1 of the intermediate spacer 16.
The intermediate spacer 16 is inserted between the flange 7 and the flange 19 of the outer cylinder 12 and lifted, and the intermediate spacer 16 is pulled upward. In such a case, the lower end of the long hole 21 comes into contact with the pin 20 so that the guide pin 4 can be pulled out from the outer cylinder 12 and pulled out.

As described above, the outer cylinder 12 is buried under the floor, and the cylindrical intermediate spacer 16 which is sufficiently shorter than the outer cylinder 12 is inserted into the outer cylinder 12 so as to be freely inserted and removed. The guide pin 4 is inserted into the cylinder 12 so as to be able to move up and down, and the flange 17 for removal is extended to the upper end of the intermediate spacer 16 so that dust enters between the guide pin 4 and the outer cylinder 12. When the movement of the guide pin 4 is hindered, the intermediate spacer 16 is easily removed by, for example, inserting a plate-like removal jig 22 into the lower surface of the flange 17 of the intermediate spacer 16. By removing the intermediate spacer 16, flexibility is provided between the guide pin 4 and the outer cylinder 12, and the guide pin 4 is pulled out of the outer cylinder 12 to easily remove dust inside. The removal of the intermediate spacer 16 is performed by using the jig 22.

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 suspension door body 3 side. When the guide pin 4 is pulled up most, the magnet 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 3 of the suspension door main body 3 to stabilize the guide function.

A locking claw 29 is provided at the lower end of the intermediate spacer 16.
Are provided so that they can be elastically displaced.
The intermediate spacer 16 is prevented from unexpectedly ascending by engaging with the recess 30 in a detachable manner. The locking claws 29 may not be provided. When the width of the opening B is W and the number of the hanging door bodies 3 disposed in the opening B is n, the pitch P between the guide pins 4 and 4 is W / n + 1.
As a result, the running groove 5
One guide pin 4 is engaged at any travel position of the suspension door body 3, and the number of the guide pins 4 is reduced while always guiding the guide pins 4, and the It is intended to prevent the appearance of the floor surface from being deteriorated by providing a large number of guide pins 4.
The width a of the suspension door main body 3 has a relationship of W / n>a> W / n + 1.

In the embodiment, the intermediate spacer 1
6 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.

[0015]

As described above, according to the present invention, the pitch between the guide pins is approximately W / n + 1, where W is the opening width of the opening and n is the number of the hanging door bodies disposed in the opening. Because
One guide pin can be engaged in the travel groove of the suspension door body at any traveling position of the suspension door body, and the number of the guide pins is reduced while always performing the guide by the guide pin, There is an advantage that the appearance of the floor surface can be prevented from being deteriorated by providing a large number of guide pins on the floor surface.
