[Conventional technology]

2. Description of the Related Art Conventionally, as a folding door connecting device of this type, as shown in, for example, Japanese Utility Model Laid-Open Nos. 59-122392 and 63-54784, there are joints provided in adjacent door structures. There has been a member in which a member is rotatably fitted separately to two shaft portions provided on a support body, and a contact portion for restricting an opening angle of a joint member is formed on the support body.

[Problems to be Solved by the Invention]

In the conventional coupling device, due to an error in the manufacturing dimensions of the support shaft and the joint fitted to it, rattling is likely to occur in the sliding part even within the intersecting range. In this case, there is a problem that the door structure rattles due to an external force such as wind pressure and becomes a jarring noise source.

The present invention has been made in view of the above circumstances, and the door structure does not become an offensive noise source due to an external force such as wind pressure even if there is some manufacturing dimensional error in the shaft portion and the joint of the support body. An object is to provide a connecting device such as a folding door.

[Means for Solving the Problems]

The folding door connecting device according to the present invention includes a support body having two first and second shaft portions, and two door structure bodies that are rotatably fitted to the first shaft portion and are adjacent to each other.

It has a tubular fitting portion and a first engaging portion protruding outside the fitting portion, and the second joint member projects to the fitting portion for the second shaft portion and the outside of the fitting portion. A second projecting portion and a second engaging portion, and engages with the first engaging portion when the one door constituent member is expanded with respect to the support member in the linking member. The contact portion that regulates the opening angle of the door structure, the first protrusion that slides in contact with the outer peripheral surface of the fitting portion of the first joint member, and the other door structure is expanded with respect to the support body. Occasionally, a contact portion that comes into contact with the second engaging portion to regulate the opening angle of the door structure and a recessed portion that accommodates the second protruding portion are provided, and the first joint member with respect to the support body. The second joint is allowed to move from the first position to the second position by allowing the fitting portion of the first joint member to escape from the position facing the first protruding portion as the support body is folded. As the member is folded with respect to the support, the second protrusion pushes the recess to move the support from the first position to the second position, and then the second protrusion forms the support and the support. When the support is slid between the second shaft portion and the support body is moved to the second position, the first protruding portion is the first joint. Those configured to protrude into the interior of the fitting portion of the return path of rotation member.

[Work]

According to the coupling device having this configuration, the operations of the door structures adjacent to each other are regulated by the first joint member, the second joint member, and the linking member while maintaining a constant relationship. That is, when the two door structures are deployed, only the first joint member can rotate about the first shaft in the folded state. Further, the supporting member is positioned at the first position with its abutting portion hitting the first engaging portion of the first joint member, so that the second joint member has its second stepped portion abutting the abutting portion of the supporting member and being in a deployed state. It is locked as it is. In the folded state of the first joint member, the second protrusion pushes the recessed portion of the support to move the support from the first position to the second position when the second joint member is folded, The second joint member can be rotated from the folded state to the folded state and vice versa. Furthermore, when both the first and second joint members are folded, only the second joint member can rotate to the deployed state about the second shaft portion, and the fitting portion of the first joint member is supported. It hits the first protruding part of the body and is locked in the folded state.

On the other hand, when the first joint member is folded or unfolded, the first protruding portion of the support body slides on the outer peripheral surface of the fitting portion to prevent rattling of the fitting portion of the first joint member, When the second joint member is folded or unfolded, the second projecting portion is sandwiched between the support body and the second shaft portion and slides to prevent rattling of the fitting portion of the second joint member. .
