するようにしてある。2. Description of the Related Art As a folding door attached to an entrance of a bathroom, for example, the one disclosed in Japanese Utility Model Publication No. Sho 62-5510 is known. The folding door includes a door frame, a first door and a second door having a door end side foldably connected to each other, and a door wheel mounted above and below the hanging side of the first door is rotatably supported on upper and lower frames of the door frame. Then, the door door mounted on the upper and lower sides of the hanging side of the second door is rotatably and slidably supported on the upper and lower rails of the door frame, and the first and second doors are moved to a linear closed position and a folded open position. It opens and closes.

ようにすることがある。[0003] Since the entrance and exit of the bathroom has a raised floor of the dressing room and a low floor of the bathroom to make it difficult for water in the bathroom to scatter to the dressing room side, the first and second doors are connected to the bathroom side. And is in a folded open position. On the other hand, if there is the above-mentioned step at the entrance, it is difficult for people to get in and out, so that the bathroom floor may be at the same height as the undressing room floor so that people can go in and out smoothly.

側下部が浴室床と干渉することがある。When the bathroom floor is at the same height as the undressing room floor as described above, when the first door and the second door protrude toward the bathroom and are in the folded open position, the first door and the lower part of the second door are closed. The vertical dimension with respect to the bathroom floor becomes extremely small, and when the first door and the second door hang down due to their own weight or the like, lower portions of the first and second doors on the side of the door end may interfere with the bathroom floor.

As shown in FIG. 1, a door roller disclosed in Japanese Patent Application Publication No. 53-53103 has a support shaft 2 attached to a door 1 and a cam 3 attached to the support shaft 2.
And a sliding body support body 4 that rotates relative to the support shaft 2
And a sliding body 5 attached to the sliding body support body 4, wherein the movable cam surface 6 of the cam 3 and the fixed cam surface 7 of the sliding body support body 4 are in contact with each other.

る。When the door 1 is in the closed position, FIG.
As shown in FIG. 1A, the cam surfaces contact each other, and the door 1 moves downward. When the door 1 is rotated by 90 degrees from this state to the folded open position as shown in FIG. Moving.

しなくなったりすることがあり、第１扉と第２扉をスム
ーズに開閉できなくなる。As described above, since the sliding body support body 4 is supported so as not to rotate with respect to the rail 8 via the sliding body 5, an excessive force acts on the sliding body 5 when the door is opened and closed. For this reason, the sliding body 5 may not rotate smoothly early, and the first door and the second door cannot be opened and closed smoothly.

くなる。Further, since the cam 3 is moved up and down by rotating by 90 degrees, the first door and the second door are raised to the uppermost position when the doors are folded and opened, so that the raising operation is slow. For this reason, the gap between the first and second doors and the bathroom floor is determined in consideration of the maximum amount of droop when the first and second doors are in the folded open position. Becomes larger.

Installation of the door roller is troublesome.
【００１３】そこで、本発明は前述の課題を解決できる
ようにした折れ戸用戸車を提供することを目的とする。Accordingly, an object of the present invention is to provide a folding door door door capable of solving the above-mentioned problems.

A rotor 50 rotatably and vertically inserted into the main body 30 and a roller 60 attached to the rotor 50. The cam surface 43 of the cam member 40 and the cam portion 52 of the rotor 50 are provided. And the cam member 40 and the rotor 50 rotate relative to each other so as to approach and separate from each other.
The pair of zero guide pieces 55, 55 project below the roller 60, and are shaped to be opposed to both side surfaces of the rail with which the roller 60 comes into contact.

When 0 rotates relatively, the cam member 40 and the rotor 50 approach and separate from each other by the cam member 40 and the cam portion 52, so that the main body 30 and the rotor 50 move up and down relatively. Further, since the pair of guide pieces 55 and 55 of the rotor 50 project below the roller 60 and face both side surfaces of the rail with which the roller 60 contacts, the pair of guide pieces 55 and 55 prevent the rotor 50 from rotating. No excessive force acts on the roller 60 when the main body 30 and the rotor 50 are moved up and down.

4. By attaching the main body 30 to the hanging frame 19 of the second door 15 and contacting the roller 60 with the upper surface of the rail 11a of the lower frame 11,
The first door 14 and the second door 15 can be moved between a linear closing posture and a folding opening posture, and when the above-mentioned closing posture and the folding opening posture are moved, no excessive force acts on the roller 60, The first door and the second door can be smoothly opened and closed for a long period of time without the roller 60 becoming unable to rotate smoothly early.
【００１９】また、本体３０にカム部材４０が着脱自在
に取付けてあるから、カム部材４０が摩耗した時には簡
単に交換できる。Further, since the cam member 40 is detachably attached to the main body 30, it can be easily replaced when the cam member 40 is worn.

転子５０が９０度よりも小さい角度相対回転するとカム
面４３とカム部５２が最大距離だけ離隔する。According to the second aspect, the cam member 40 is provided on the lower surface 41a of the circular peripheral wall 41 with a pair of substantially V-shaped cam surfaces 4.
Since the rotor 50 has a pair of substantially mountain-shaped cam portions 52, 52, when the cam member 40 and the rotor 50 rotate relative to each other by an angle smaller than 90 degrees, the cam surface 43 and the cam portion are rotated. 52 are separated by a maximum distance.

The maximum stroke rises before the fourth and second doors 15 are completely folded and opened.
【００２２】したがって、上昇動作が速く、第１扉・第
２扉と浴室床との間の隙間を小さくすることができる。Therefore, the ascending operation is fast, and the gap between the first and second doors and the bathroom floor can be reduced.

５２がほぼ山形状であるから、カム部材４０と回転子５
０が左右どちらに相対回転しても回転子５０とカム部材
４０が接近・離隔する。Since the cam surface 43 is substantially V-shaped and the cam portion 52 is substantially mountain-shaped, the cam member 40 and the rotor 5
The rotor 50 and the cam member 40 approach and separate from each other regardless of whether the rotation of the rotation member 0 is right or left.
【００２４】これによって、第１扉１４の吊元框１９と

When one of the guide pieces 55 is relatively rotated, one of the pair of guide pieces 55 comes into close contact with one side surface of the rail and is elastically deformed.
However, since the pair of guide pieces 55 are connected by the connecting piece 58, they do not spread. Thus, it is possible to prevent the guide piece 55 from being elastically deformed when the door is opened and closed, and the guide piece 55 from being resiliently restored to collide with the rail and generating noise.
