Description

The present invention relates to a sealing mechanism in a hanging door device capable of closing a gap generated between a lower edge of the hanging door and a floor surface when the hanging door is closed.

As a sealing mechanism in this type of hanging door device, a closing body provided with guide rollers on the door end side and the door bottom side is fitted on the lower frame of the door body so as to be movable up and down. The running surface of the door is provided with a concave groove in which the door tip side guide roller slides at the door closing position, and the running surface of the door edge side guide roller is provided on the running surface of the door edge side guide roller. Some have guide rails to guide them down. (For example, refer to Patent Document 1.)

In this case, since the groove where the door-side guide roller formed on the running surface of the door-side guide roller slides is located on the floor surface of the entrance / exit, when an elderly person or a disabled person enters or exits, The wheel fell once into the groove when the wheel fell over or fell in a wheelchair, or when a stretcher or the like passed, and smooth traffic could not be made.
Moreover, in the said structure, since the door-end side and the door-end side guide roller always drive | work on a floor surface (on a guide rail), the unpleasant driving sound was generated at the time of opening and closing of a door.
And this running sound was very annoying in places where quietness was required such as hospital rooms (especially at night).

On the other hand, as a solution to the above problem, a driving lateral body supported so as to be movable in the opening and closing direction is provided at the lower end of the hanging door, and when the driving lateral body moves in the door opening direction relative to the suspension door, When the closing elevator is lowered and the drive lateral body moves in the door closing direction with respect to the suspension door, the two are interlocked and connected so as to raise the gap closure elevator, and before closing the suspension door reaches the closed position. A contact portion (hereinafter referred to as a contact portion) formed on the door butt side end of the drive laterally movable body in contact with a fixed-side contacted portion (hereinafter referred to as a contacted portion) provided in the wall; The lifting / lowering body for closing the gap is moved downward from the lower end of the suspension door by moving the suspension door to the closed position. The lower end of the suspension door as the suspension door is opened. So as to increase, a first locking means for maintaining in the raised position the gap closing for the lifting body having a structure in which a second locking means for maintaining the lowered position has been proposed. (For example, see Patent Document 2.)

In the above case, the abutted part provided in the wall is located in the gap closing elevator body and has the purpose of preventing the roll (running in the front-rear direction) when the hanging door is opened / closed. In order to prevent the portion from contacting the gap closing elevator and affecting the lifting operation of the gap closing elevator, between the lower end inner surface of the suspension door and the gap closing elevator, and the gap closing elevator inner surface And a predetermined clearance is required between the contacted portions. However, due to this clearance, the abutted part and the inner surface of the lower end of the suspension door cannot be in close contact with each other, and the roll during the opening and closing of the suspension door cannot be sufficiently prevented.
In addition, in order to prevent the lifting / lowering body for closing the gap from being raised and lowered unexpectedly when the hanging door is opened and closed, the first locking means and the second locking means must be provided, which increases the number of parts and increases the cost. It was.

In addition, the size of the gap between the lower end of the suspension door and the floor surface varies depending on the suspension door installation position depending on the suspension state of the suspension door and the floor surface. It is necessary to adjust the raising / lowering range of the lifting / lowering body for closing the gap so that the lower end of the lifting / lowering body just contacts the floor surface. That is, according to the size of the gap between the lower end of the suspension door and the floor surface, the position where the contact portion comes into contact with the contacted portion (position where the contact portion is locked by the second locking means). In the above case, the position of the abutment part can be adjusted in the direction of movement of the driving laterally moving body. Therefore, the position of the contact portion cannot be adjusted when the suspension door is suspended. For this reason, in order to obtain the optimal descending width of the gap closing lifting body, the suspended door is temporarily removed, the position of the contact portion is adjusted, and the suspension door is suspended again after the adjustment is completed. The workability was very bad.
