Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a top-hanging sliding door, and more particularly to a top-hanging sliding door that enables adjustment of the building in the thickness direction of the door body.

[0002]

2. Description of the Related Art An upper sliding door is provided with a suspension car on the upper part of a door body, and the suspension car is supported by a guide rail provided on an upper frame so that the door body can be opened and closed in the left-right direction. Is used as a means for closing an opening communicating with the. This upper sliding door does not need to have a sill or rail on the floor and can have a flat floor surface, and is therefore suitable for constructing a stepless house in which a wheelchair can be used.

In such an upper sliding door, it is known that the wheel portion of the suspension vehicle can be moved and adjusted in the vertical direction so that the building can be easily adjusted in the vertical direction. (For example, the actual exploitation 59-1386
79 gazette, Japanese Utility Model Publication No. 5-6367 gazette, etc.).

[0004]

However, in the above-mentioned hanging door, although it is possible to easily adjust the building in the vertical direction of the door, it is difficult to adjust the building in the thickness direction of the door. . When the construction adjustment in the thickness direction of the door was intentionally performed, the mounting position of the suspension vehicle had to be changed, which was a difficult task. Actual fairness 8-700
Japanese Unexamined Patent Publication No. 6 describes a suspension car type runner in which a shaft insertion hole provided in a mounting bracket is made to be an elongated hole so as to be able to cope with a change in the thickness of a door body. Since the vertically long screw shaft is inserted into the mounting hole formed at the upper end of the door body through the female screw cylinder, the wheel portion is not moved in the door body thickness direction unless the mounting hole is re-formed. It is difficult to move.

Therefore, an object of the present invention is to provide an upper sliding door which can be easily adjusted in the building thickness direction.

[0006]

In order to achieve the above object, a hanging door according to the present invention is provided with a hanging wheel on the upper part of a door body, and the hanging wheel is supported by a guide rail provided on an upper frame. The body can be opened and closed in the left-right direction, and the suspension vehicle has a base portion provided on the door body, a wheel portion and an operation portion provided on the base portion, and the operation of the operation portion causes the base portion to operate in conjunction with the operation portion. It is characterized in that it is configured to be movable and adjustable in the thickness direction of the door together with the body.
