Description

  The present invention relates to a hanging door and a hanging door device having a function of absorbing an impact applied to a door panel.

  In a typical hanging door, a wheel is attached to an upper end portion of a plate-like door panel via a hanging metal fitting, and this wheel is hooked on an upper rail so as to run freely. Therefore, when an impact is applied to the door panel, the impact is transmitted to the hanging bracket and the wheel, and the wheel may be detached from the upper rail. Moreover, when the rail structure which a wheel does not detach | leave is employ | adopted, there existed a possibility that an unexpected force might act on a suspension metal fitting and a wheel, and these might be damaged.

  In view of this, conventionally, various types of hanging doors having a function of absorbing an impact applied to the door panel (that is, a buffering function) have been developed, and examples thereof are disclosed in Patent Documents 1 and 2, and the like.

  In the hanging door 1a disclosed in Patent Document 1, as shown in FIG. 12, a hanging fitting 3a is attached to the upper end surface of the door panel 2a, and the lower end of the hanging fitting 3a arranged below the upper rail 5a. A rubber block 4a is attached to the base. Therefore, when the door panel 2a is lifted by the “vertical direction” impact applied to the door panel 2a, the block 4a is brought into contact with the upper rail 5a, and the impact is absorbed by the block 4a.

On the other hand, in the hanging door 1b disclosed in Patent Document 2, as shown in FIG. 13, the lower end portion of the hanging fitting 3b provided with the flange 6b is arranged inside the door panel 2b, and the flange 6b and the door panel are arranged. A cushioning material 4b made of an elastic material is disposed between the inner upper surface of 2b. Accordingly, when an impact in the “vertical direction” is applied to the door panel 2b, the impact is absorbed by the cushioning material 4b before being transmitted to the hanging bracket 3b.
