Description

[Detailed description of the invention] The present invention relates to a connecting structure for two-folding doors, and more specifically, the side ends of the door body 1 are rotatably connected to each other to form a two-folding door 2. An upper runner 5 is provided at both ends of the upper edge of the folding door 2 via a support member 3 to the upper rail 4, and a lower rail 7 is provided at both ends of the lower edge of the bifold door 2 via a holding member 6. This relates to a connecting structure of two folding doors, in which a lower runner 8 that can run freely is provided, and a supporting member 3 and a holding member 6 are detachably connected by a connecting means 9.

The object of the present invention is to provide a door device in which a plurality of sets of bifold doors, each of which is constructed by rotatably connecting the side ends of the door body, are installed on upper and lower rails via runners. By effectively utilizing the structure of each bifold door, the connection structure of the bifold doors can be simplified, and the bifold door connection structure requires only simple improvements to the existing bifold doors. Our goal is to provide the following.

Embodiments of the present invention will be described in detail below with reference to the drawings.

Fig. 1 shows a folding door A, in which two sets of bifold doors 2, in which two door bodies 1, 1 are pivotally connected so that they can be folded, are provided at the opening of the room, with an upper rail 4 and a lower rail 7. It was installed in between so that it could run freely. 2
An upper runner 5 is rotatably attached to both ends of the upper edge of the sheet-folding door 2 via a column 10 as an example of a support member 3 and a bearing member 11. bifold door 2
A lower runner 8 is rotatably attached to both ends of the lower edge of the holding member 6 via struts 12 as an example. The strut 10 and the strut member 12 are non-rotatably attached to the door body 1.

3, 4 and 5 show different embodiments of the connection means 9, and the one in FIG.
Locking holes 15, 15 are formed at both ends of the support members 3, 3, as shown in FIG.
The struts 10, 10 of the holding member 6 are rotatably and elastically locked, and the struts 12 of the holding member 6 are rotatably and elastically locked in the locking holes 15, 15, thereby connecting the bifold doors 2 together in a freely foldable manner. It is something. FIG. 4 shows another example of the connecting means 9, in which magnets 16, 16 are connected to bearing members 11, 11 which are rotatably and pivotally connected to the column 10.
Furthermore, the magnets 16, 16 are attached to the lower runners 8, 8, and the bearing members 11, 11 and the lower runner 8 are connected by the magnetic attachment of the magnets 16, 16, and the supporting members 3, 3 and The holding members 6, 6 are connected to each other to connect the bifold doors 2, 2 in a bendable manner. In addition, in the above embodiment, a magic tape may be used instead of the magnet 16. FIG. 5 shows still another embodiment of the connecting means 9, in which a fitting projection 17 and a fitting recess 18 which can be freely engaged with and detached from the fitting protrusion 17 are used in place of the magnet 16 of the above-described embodiment.

In summary, the present invention constructs a bifold door by rotatably connecting the side ends of the door body, and runs on the upper rail via support members at both ends of the upper edge of the bifold door. A movable upper runner is provided, and a lower runner is provided at both ends of the lower edge of the bi-folding door so that it can run freely on the lower rail via a holding member, and the supporting member and the holding member are detachably connected by a connecting means. Therefore, by effectively using the supporting members necessary to support the upper runner and the holding members necessary to support the lower runner, and by rationally setting their placement positions, the support can be improved. By connecting the member and the holding member using the connecting means, there is an advantage that two sets of bifold doors can be easily connected and the connection structure thereof can be simplified. Furthermore, since the two-folding doors can be connected one after another, the opening and closing operations can be simplified instead of opening and closing the two-folding doors individually in the conventional method.
