BEST MODE FOR CARRYING OUT THE INVENTION The present invention will now be described in detail with reference to the illustrated embodiments. The folding door (1) has two door bodies (3) foldably connected via a hinge (2) and upper and lower ends of each door body (3) on the opposite side of the hinge (2). It consists of a runner (A) to be installed. The runner (A) runs along the guide rails (4) installed on the opening or the ceiling and floor of the room. The cross-sectional shapes of the ceiling and floor guide rails are slightly different (of course, they may have the same shape.)
However, both of them are rail grooves that run when the runner (A) is fitted.
Since the point having (5) is the same, the ceiling and floor guide rails are represented by the same (4).

The runner (A) rolls in the rail groove (5) 4
The individual plastic roller (20), the runner main body (10) that rotatably supports the roller (20) by entering the guide rail (4) through the rail opening, and the central portion of the runner main body (10). It is composed of a runner main shaft (16) penetrating up and down, and a mounting bracket (17) for fixing the runner main shaft (16) to the door body (3). The runner body (10) is a flexible plastic molded product.

The mounting metal fitting (17) is fitted into the recessed groove (30) formed at the end of each door body (3), and the lever (31) provided on the mounting metal fitting (17) is operated to operate the above. It can be attached to and detached from the groove (30). Also, the runner spindle (16) is a compression spring.
It is slidably attached to the mounting bracket (17) via (18). An engaging arm (11) is provided so as to project from one end of the runner body (10).

The shape of the engagement arm (11) is not particularly specified as long as the runners (A) are structured to automatically and firmly engage each other when they are brought close to each other. Here, a case where the main arm member (12) and the sub arm member (13) are configured will be described as a typical example. Main arm member (1
2) and the sub arm member (13) are provided so as to project from one end of the runner body (10) in parallel and with a slight vertical shift. An engaging recess (14) is provided on the surface of the main arm member (12) on the side of the sub arm member (13), and the main arm member (12) of the sub arm member (13) is provided.
An engaging projection (15) is provided at the tip of the side surface. Since the main arm member (12) has a slightly larger cross section than the sub arm member (13), it is more difficult to bend than the sub arm member (13).
Both the main and sub arm members (12) and (13) can slightly bend when they are engaged or disengaged.

The stopper (B) is attached to the end of the guide rail (4) and is a plastic stopper body.
The compression spring (42) is arranged in the recessed hole (41) formed in (40), and has the same shape as the main arm member (12) with which the sub arm member (13) of the runner (A) engages. The stopper body (44) having the engaged arm (43)
It is firmly attached to the attachment hole (46) formed at the end of the guide rail (4) by the saw-toothed protrusion (45) formed on the outer surface of the (40).

Thus, as shown in FIG. 1, the upper and lower runners (A) of the folding doors (1) are fitted in the guide rails (4) installed in parallel to the ceiling and floor, and the guide grooves ( Allow the roller (20) to run along 5). When the folding doors (1) are folded in such a state, the door body (3) of the adjacent folding doors (1)
Are in close proximity. At this time, runners of doors (3) adjacent to each other
Engaging arms (11) project from (A) so that the engaging arms (11) engage with each other when the runners (A) approach each other.

That is, when the runners (A) come close to each other, the sub arm member (13) of one runner (A) bends and slides on the main arm member (12) of the other runner (A),
(A) One sub arm member when they are close enough
The engaging projection (15) of (13) fits into the engaging recess (14) of the other main arm member (12) and is firmly engaged by the two pairs of main and sub arm members (12) and (13). Fit. Such engagement is performed in the upper and lower runners (A) to firmly fix the ends of the folding door (1). The plurality of folding doors (1) thus folded are joined by the adjacent runners (A) and moved along the guide rail (4) to the end of the guide rail (4).

Since the stopper (B) is provided at the end portion of the guide rail (4) as described above, the engaged arm (43) of the stopper (B) has a door body (on the stopper (B) side). While the sub arm member (13) of the runner (A) of 3) is flexed, the engagement recess (43a) slides in and the two are joined. As a result, the plurality of folded folding doors (1) joined by the runner (A) are housed in the ends of the guide rails (4) and well fixed.

Next, a description will be given of a case where a plurality of folded folding doors (1) which are housed in the ends of the guide rails (4) and well fixed are pulled out to partition the opening or the room. When the folding door (1) folded as described above is pulled out, the runners (A) between the door bodies (3) of the adjacent folding doors (1) and the runners on the stopper (B) and the stopper (B) side ( Since A) is connected to each other, the folding doors (1) are expanded one after another with the folding door (1) on the stopper (B) side as the fixed side. Then, when the door bodies (3) of the folding doors (1) adjacent to each other do not fully extend, their ends contact each other, and when the folding doors (1) are expanded as they are, as shown in FIGS. Engaging arm when folded
From the distance (S) between the runner spindles (16) when engaged by (11), the ends of the door body (3) are in contact with each other.
Since the distance (H) between 6) is larger, the engagement by the engagement arm (11) is released according to the expansion of the folding door (1). The opening or room can be partitioned by the folding door (1) by straightening the folding door (1). At this time, the ends of the door body (3) of the folding door (1) are in contact with each other.

[0019]

According to the present invention, a plurality of folding doors attached to and folded on a guide rail are engaged with each other when they are close to each other, or to the end of the guide rail when they are close to the end of the guide rail. Since the engagement arm that engages with the engaged arm protruding from the installed stopper is protruding from the runner body, the multiple folding doors attached to the guide rails are close to each other when folded. At this time, the engaging arms engage with each other and the engaging arm and the engaged arm engage with each other, so that a plurality of folded folding doors can be fixed to the ends of the guide rails. Furthermore,
When the folding doors are folded and moved, since the adjacent folding doors are kept connected by the runner, it is possible to move all folding doors in a connected state.
