When the downward concave portion and the upward concave portion face each other as the hanging door is opened and closed, the magnetic body and the magnet are attracted to each other by the magnetic force, and one protrudes from the concave portion and both Since it is locked across the recess of the door, it is possible to prevent the hanging door from swinging. Further, since the magnet is rotatably supported, even if the magnetic body and the magnet are attracted to each other, they are separated and no friction occurs. Furthermore, the magnet moves smoothly forward and backward by rotating. These actions allow the hanging door to slide smoothly.

Embodiment An embodiment of this invention will be described based on FIGS. 1 to 3. That is, as shown in FIG. 1, this hanging door sway prevention device includes a downward recess 2 provided in the lower end surface 9 of the hanging door 1 along the width direction of the hanging door 1, and a lower end surface of the hanging door 1. an upward recess 3 provided on a floor surface 10 opposite to the above-mentioned downward recess 2;
Magnetic material 4 such as a magnet or iron plate installed on the top (bottom) of the
and an upward recess 3 provided in the upward recess 3
and a magnet 5 which is inserted into the downward recess 2 by attracting the magnetic body 4 and rotating freely forward and backward while facing the downward recess 2 .

As shown in FIG. 1, the downward recess 2 is a groove provided in the lower end surface 9 of the hanging door 1 along the width direction of the hanging door 1, and the guide pin 18 is inserted as shown in FIG. It is locked. Further, the side opening of the groove is closed by a door stop cushion 7 attached to the side surface of the hanging door 1.

The upward concave portion 3 is provided near the door frame 6 on the floor surface 10 facing the lower end surface 9 of the hanging door 1 .
As shown in FIGS. 2 and 3, a semicircular magnet 5 is provided in the upward concave portion 3, with the downward concave portion 2 and the upward concave portion 3 facing each other, and rotates by attracting the magnetic body 4. It will be done. The magnet 5 is housed in a casing 12a that fits into the upward recess 3, and is rotated by a shaft 14 attached near the upper opening 13 of the casing 12a so that it can move forward and backward from the upper opening 13 of the casing 12a. Possibly supported. Upper opening 13 of casing 12a
A flange 12b is provided on both sides of the flange 12b, and the flange 12b is fixed on the floor 10 adjacent to the upward recess 3, and the fixing screw 8 is inserted into the floor 10 through the insertion hole 11 provided in the flange 12b. Screw in casing 1
Fix 2a (Figure 1). In the normal state, the upper opening 13 of the casing 12a is closed by the flat part of the semicircular magnet 5, and when the magnetic body 4 approaches, the magnet 5 rotates around the shaft part 14 due to its magnetic force. It protrudes from the upper opening 13 of the casing 12a. When the magnetic body 4 moves away from the casing 12a, the magnet 5 moves toward the casing 12a due to its own weight.
The upper opening 1 of the casing 12a is rotated inward again.
Block 3.

Next, the operation of this embodiment will be explained based on FIG. When the hanging door 1 is closed, the magnetic body 4 and the magnet 5 face each other and are attracted to each other by magnetic force, so that the magnet 5 rotates in the direction of the arrow and the part that protrudes from the upward recess 3 becomes the downward recess 2. inserted within. Next, when opening the hanging door 1, the magnet 5 hits the door stop cushion 7 provided on the side of the hanging door 1 that contacts the door frame 6, and the magnet 5 is returned to the upward recess 3 by its own weight. .

In this way, when the hanging door 1 is closed, the downward recess 2 and the upward recess 3 are facing each other, and the magnetic body 4
Since the magnets 5 and 5 attract each other and the magnets 5 are locked in the recesses 2 and 3, the hanging door 1 can be prevented from swinging back and forth.

In addition, the hanging door sway prevention device of this example is as follows:
Needless to say, it can be used in conjunction with conventionally used guide pins (in this case, the guide pin is placed in the center and the anti-slip device is provided on both sides or one side), and it can also be used in place of the guide pin. .

Further, in this embodiment, a magnetic body 4 is provided in the downward recess 2, and a magnet 5 that can freely move forward and backward into the upward recess 3.
However, on the contrary, a magnet that can move forward and backward may be provided in the downward recess 2, and a magnetic material may be provided on the bottom surface of the upward recess. In this case, the magnet in the downward recess is rotated downward by magnetic force and inserted into the upward recess to prevent the hanging door from swinging. In order to return the magnet protruding from the downward recess into the downward recess, for example, a return spring or the like (not shown) is attached to the shaft of the magnet to force the magnet back into the downward recess. However, the spring force of the return spring needs to be smaller than the mutually attracting magnetic force between the magnet and the magnetic body.

[Effect of idea]

According to the hanging door sway prevention device of this invention, a downward recess and an upward recess are provided on the lower end surface of the hanging door and the floor surface opposite to the lower end surface of the hanging door, respectively, and rotation is made in one of the downward recess and the upward recess. A magnet is freely pivotable so that it can move forward and backward from one of the recesses, and a magnet provided in the other of the downward recess and the upward recess faces the magnet and attracts each other at a distance so that the magnet straddles both recesses. When the downward recess and the upward recess face each other when the hanging door is opened or closed, the magnetic body and the magnet are attracted to each other by the magnetic force, and one side is pulled from the recess. Since it protrudes and is locked across both recesses, it is possible to prevent the hanging door from swinging. Further, since the magnet is rotatably supported, even if the magnetic body and the magnet are attracted to each other, they are separated and no friction occurs. Furthermore, the magnet moves smoothly forward and backward by rotating. These actions have the effect of allowing the hanging door to slide smoothly.
