DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door connecting structure for a folding door which can be folded in a zigzag shape.

[0002]

2. Description of the Related Art In general,
In this type of folding door, while connecting the door bodies together so that they can be freely folded in a zigzag shape via a connecting member,
Of the connecting members, every other odd-numbered connecting member includes
In some cases, a traveling roller that moves along a guide rail on the skeleton side is attached. By the way,
For example, when this is a hanger-type hanging door, the folding doors are connected and formed in a series in advance, and each traveling roller of the folding door is sequentially hung on a guide rail. However, since this assembling work is performed with a folding door in which a plurality of door bodies are connected, when the number of door bodies is large, when the door body size is large, and when the door body weight is heavy, it is very It was cumbersome and couldn't be done alone.

Therefore, as shown in Japanese Utility Model Publication No. 2-45432, an even-numbered connecting member having no traveling roller is connected to a female joint piece and a male joint piece fitted to the female joint piece. There has been proposed a structure in which the two joint pieces are detachably fastened to each other by an indenter type. However, this is a nut-screw for fixing the two joint pieces,
Since it is structured to be attached only from the front side that protrudes in the folded state of the folding door, if the front side is installed so that it faces the outdoor side, the unskilled person removes the nut-screw from the outdoor side Since the connecting member can be disassembled, there is a problem in crime prevention.

Further, since the odd-numbered connecting member provided with the traveling roller is not of the above-described vertically nested type, after the folding door is installed, it is necessary to repair or replace the door body partially. If you want to do maintenance,
There is a disadvantage that the door bodies incorporated in the odd-numbered connecting members cannot be removed one by one. Therefore, it is conceivable that the odd-numbered connecting member is of the vertically nested type. At this time, a traveling roller is attached to one of the joint pieces. However, in this case, a mounting space and a mounting member for the traveling roller are separately required on the one joint piece, and the door on which the traveling roller is not attached is required to remove the door body incorporated in the joint piece on the side. Things also come off at the same time, making the work cumbersome and complicated. Furthermore, in order to remove the door body that is pivotally attached to the joint piece on the side where the traveling roller is attached, the traveling roller must be removed from the joint piece. However, there is a problem in that the security is impaired.
