Description

  The present invention relates to a folding door device provided in an opening of a building such as a store, a house, or a public facility. In detail, it is related with the folding door apparatus which can fold the provided door body smoothly and appropriately.

  When the folding door device is opened, a plurality of doors provided in the folding door device are folded and arranged in a substantially indoor / outdoor direction, and are arranged together at the end of the opening. Therefore, the opening can be used widely and effectively when the door is opened. On the other hand, when the door is closed, the inside can be seen or light can be taken in by the glass panel provided on the door. From such convenience, it has been increasingly used as a substitute for a shutter in a store, for example.

  The folding door device has a frame body attached along the four sides of the building opening, and a plurality of door bodies arranged inside the frame body. The plurality of doors are adjacent doors and include hinges that rotatably connect the widthwise ends of the doors. And it is comprised so that opening and closing of a folding door apparatus can be performed because a door can be folded and expand | deployed. Specifically, when the door is folded, the doors are arranged substantially parallel to the indoor / outdoor direction, and are arranged so as to be gathered at either the left or right end of the opening to open the opening. . On the other hand, when the door is deployed, the door is arranged over the entire frame in parallel to the opening, thereby closing the opening.

  In the folding door device having such a configuration, when the door is expanded (opening closed) to the folded (opening opening), the doors are arranged at both ends of each door. One of the hinges moves along the upper and lower horizontal frames of the frame, and the other moves so as to protrude to the indoor side or the outdoor side. Therefore, the door is moved along the opening in the folding process, and its direction is rotated in the direction of about 90 degrees.

  The door is smoothly folded by appropriately performing such movement and rotation. However, in the conventional folding door device, when trying to open the folding door device, there is a case where none of the door bodies starts to be folded and cannot be moved in the deployed posture. This is because the force for opening the folding door device is not converted into a force for folding the door body indoors or outdoors, and the door body is not properly folded.

  In order to solve such a problem, Patent Document 1 discloses a mechanism for moving the door body indoors and outdoors when the door body is folded. This is to facilitate the folding of the door body by using a torsion spring disposed at the connecting portion of the door body. In addition, the folding door device described in Patent Document 1 includes a block having a slope provided in the frame body and a cam provided in the door body and sliding in contact with the block. The body can be moved indoors and outdoors.

  However, in the conventional folding door apparatus, it is still required to solve the above problem. Moreover, in the thing by the torsion spring described in patent document 1, at the time of expansion | deployment of a door, the torsion spring is always urged | biased in the direction which tries to fold a door, and also tries to fold also to a door. Since the force was working, it was difficult to take a stable deployment posture. In addition, regarding the door moving means based on the relationship between the block and the cam described in Patent Document 1, it is not preferable to extend the moving means to the outside of the frame, so that the door is directed indoors and outdoors. There was a limit to the size that could be moved to. Therefore, it has been difficult to cope with diversification of folding door devices in recent years.

  Then, this invention makes it a subject to provide the folding door apparatus which can perform folding of a door body appropriately and smoothly while being excellent in an external appearance from this viewpoint.
