Description

Description: TECHNICAL FIELD The present invention relates to a folding door connecting device configured by connecting a plurality of door structures.

[Conventional technology]

Conventionally, as a folding door connecting device of this type, as shown in, for example, Japanese Utility Model Laid-Open No. 63-54784, two joint members provided on adjacent door structures are arranged side by side on a support body. There was one that was rotatably fitted to each of the two shafts.

[Problems to be Solved by the Invention]

When a folding door provided with such a connecting device is installed in a laterally open type, for example, an engaging mechanism (a hanger roller or the like) provided at an end portion of a support body as disclosed in the above publication.
Is fitted in the groove portion of the guide rail, and the groove wall of the guide rail is subjected to troublesome work such as forming a notch portion that allows the engagement mechanism to be fitted and removed at a location corresponding to the storage space of the door structure. Was necessary.

Further, in the folding door in which the notch is formed in the guide rail as described above, when the door is opened, every other engaging mechanism is sequentially withdrawn from the notch so that the plurality of door components are folded into the storage space. On the other hand, when the door is closed, the engaging mechanism that is pulled out from the cutout portion is configured to sequentially enter the groove portion of the guide rail from the cutout portion,
It is necessary to double-provide the guide rail with the groove portion having the cutout portion and the groove portion not having the cutout portion, and it is necessary to use the guide rail having a complicated structure.

The present invention has been made in view of the above circumstances, and it is not necessary to perform troublesome work such as forming a notch in the guide rail or to use a complicated guide rail having a structure having a double groove. An object is to provide a connecting device such as a folding door.

[Means for Solving the Problems]

A folding door connecting device according to the present invention includes a support having three shafts arranged in parallel with each other, a linking member rotatably fitted to a central first shaft of the three shafts, A first joint member that rotatably fits to a second shaft portion arranged on one side of the first shaft portion and connects one door constituent body of two adjacent door constituent bodies to the second shaft portion. And a second joint member that is rotatably fitted to the third shaft portion arranged on the other side of the first shaft portion and connects the other door structure to the third shaft portion. Projections are formed at two locations in the rotational direction, the first joint member is provided with a first engagement portion corresponding to one projection portion, and the second joint member is provided with a first engagement portion corresponding to the other projection portion. A second engaging portion, a third engaging portion, and a recess formed between the second and third engaging portions are provided to deploy the two door structures. When one of the protrusions is released to the outside of the rotation path of the first engaging portion, and the first engaging portion is arranged at a position that prevents rotation of the one protruding portion, The protrusion fits into the recess and protrudes into the rotation path of the second and third engaging portions,
When one door structure is folded around the second shaft portion, the first engaging portion is released to the outside of the rotation path of the one protruding portion, and the other door structure further moves the third shaft portion. When folded around the center, one of the protrusions is arranged at a position that protrudes into the rotation path of the first engaging portion to prevent return rotation of the first engaging portion, and the second engaging portion is The other protrusion is configured to protrude into the rotation path of the other protrusion to prevent return rotation of the other protrusion, and the other protrusion protrudes into the rotation path of the third engagement portion.

[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 unfolded, only one door structure can rotate about the first shaft in a folded state, and the other door structure is locked in the unfolded state. Then, when one of the door components is folded, the other door component can be rotated about the second shaft portion into the folded state, and conversely, can be rotated from the folded state to the deployed state. Furthermore, in a state where both of the two door structures are folded, only the other door structure can rotate about the second shaft portion in the deployed state,
One door structure is locked in the folded state.
