Description

  The present invention relates to a hanging device for a hanging folding door and a hanging folding device having the same.

  The folding door includes at least two door plates, and connects adjacent door plates to each other via a center hinge so as to be rotatable in a horizontal direction, and the upper end of the door plate is connected to a rail laid above the runner via a runner. By supporting it movably, the door plates are structured to open and close while rotating.

  As described above, the folding door opens and closes while the door plates rotate, so that when the door is closed, the door plates abut against the left and right door frames and the crest surfaces of the door plates abut against each other. For this reason, when the door is suddenly rotated to the end when the folding door is closed, a large impact sound or vibration is generated. Repeated application of this impact to the folding door or door frame causes the parts to be damaged or deteriorated earlier. There is also a problem peculiar to folding doors, in which the doorboard once closed to the end bounces off due to an impact, and the doorboards are folded in a semi-closed state.

  As a conventional technology that brakes sudden rotation of the door plate when the hanging folding door is closed, the damper is integrally fixed to a slider that slides along the rail together with the runner, and the damper is compressed by the door plate when the folding door is closed. There is one configured to generate a braking force by (Patent Document 1).

[Action]
In the folding door device 1 configured as described above, when the folding door 10 is closed, if the angle between the door plates 11 and 12 is approximately 125 degrees or more, the catch mechanism of the center hinge 20 is activated, and the folding door 10 is forced. To the most closed state (completely closed state). On the other hand, when the angle between the door plates 11 and 12 is approximately 125 degrees or more, the tip of the output shaft 47B of the damper 47 comes into contact with the door plate 11, and the output shaft 47B is rotated as the door plate 11 rotates in the closing direction. It is pushed to the damper main body 47A side. Thereby, the damper 47 is compressed and the braking force of the damper 47 acts on the door plate 11. By a series of these operations, when the folding door 10 is closed, that is, after the catch mechanism of the center hinge 20 starts to work, the door plates 11 and 12 are prevented from suddenly turning, and the folding door 10 is forcibly and quietly closed.

  In the folding door device 1, of the pair of left and right door plates 11, 12 constituting the folding door 10, the right door plate 12 is connected to the right vertical frame member 51 </ b> R, and the left door plate 12 is connected via the suspension device 40. Contrary to this, the left door plate 11 is connected to the left vertical frame member 51L, and the right door plate 12 is connected to the rail 30 via the suspension device 40. In this case, it is possible to easily cope with reversing the mounting positions of the slide hinge 42 and the damper 47 with respect to the suspension block 46. That is, in the above example, the slide hinge 42 is attached to the left damper attachment portion 48F of the suspension block 46, and the damper 47 is attached to the right damper attachment portion 48R, but the damper 47 is attached to the left damper attachment portion 48F. And the slide hinge 42 is attached to the damper mounting portion 48R on the right side.

  As described above, the suspension device 40 can appropriately change the mounting position and the mounting direction of the slide hinge 42 and the damper 47 with respect to the suspension block 46 according to use conditions. It can be used as a device.

  In addition, even in an existing hanging folding door device that is installed in an opening of a building or the like without the damper 30, the damper 30 is retrofitted to the hanging block 46 so that the folding door 10 is suddenly turned due to a sudden rotation. Problems can be resolved afterwards.

  Further, when it becomes unnecessary to prevent the folding door 10 from being roughly closed after the damper 30 is mounted for some reason, the damper 30 can be removed from the suspension block 46. In addition, the damper 30 can be easily replaced.

  In the above embodiment, of the pair of left and right door plates 11 and 12 constituting the folding door 10, only one door plate 11 is connected to the rail 30 via the suspension device 40, and the other door plate 12 is the vertical frame member 51R. It is also possible to connect both door plates 11, 12 to the rail 30 via the suspension device 40.
