DETAILED DESCRIPTION OF THE INVENTION
A first embodiment of a folding door contact preventing apparatus according to the present invention will be described in detail with reference to FIGS.
FIG. 1 shows a state in which the contact prevention device is viewed from above when the folding door is unfolded. Each panel 2 and 3 of the folding door 1 has an attachment shaft (rotation center) 4 at the center of the upper end surfaces 2a and 3a of the panels 2 and 3, respectively. As shown in FIG. The folding door 1 is attached to the ceiling 12 so as to be pivotally supported by a runner 5a that travels in a rail 5 attached to 12 or the like. As shown in FIG. 1, the side end panel 2 of the folding door 1 has a buffer member 2b attached to the side end. Next to the side end panel 2, the intermediate panel 3 is connected via a hinge 1a. The folding door 1 is attached to the ceiling 12 in this way, and has a similar rotation shaft at the center of the lower end surface, and is pivotable to a runner in a rail disposed on the floor surface or the like. It may be supported.
[0007]
The contact prevention device has two links, a first link 6 and a second link 10. One end 6a of the first link 6 is located on the side end surface 2c of the buffer member 2b of the side end panel 2, and at the center portion, between the mounting shaft 4 of the side end panel 2 and the side end surface 2c. It is pivotally supported in the vicinity so that it can rotate horizontally. One end portion 10a of the second link 10 is pivotally supported on the other end portion 6c of the first link 6 so as to be swingable horizontally. The other end portion 10b of the second link 10 is pivotally supported by the end portion on the side end panel 2 side of the upper end surface 3a of the intermediate panel 3 so as to be swingable horizontally through the long hole 10c. The total length of the first link 6 and the second link 10 is determined in this way. Further, the second link 10 folds the folding door 1 as shown in FIG. 2 with a crank portion 10d for avoiding contact with the mounting shaft 4 of the side end panel 2 when the folding door 1 is unfolded. At this time, it has a notch 10e for avoiding contact with the rotating shaft 4 of the intermediate panel 3.
[0008]
As shown in FIG. 3, the 1st link 6 has the guide 7 in the edge part 6a. The guide 7 is rotatably attached to the end portion 6 a of the first link 6 and travels in the rail 5 so that the end portion 6 a of the first link 6 is always located directly below the rail 5. Regulate movement. The position of the rotation center 6b of the first link 6 shown in FIG. 2 is such that when the folding door 1 is folded, the guide 7 of the first link 6 is brought into contact with the runner 5a of the side end panel 2 as shown in FIG. Set to be close.
[0009]
Next, the operation of the contact prevention device for the folding door will be described with reference to FIG. 1, FIG. 3, and FIG.
As shown in FIG. 1, when the folding door 1 is unfolded, the end 6 a of the first link 6 is located on the side end surface 2 c of the side end panel 2, and this end 6 a contacts the wall surface 11. Therefore, the buffer member 2b of the side end panel 2 does not directly contact the wall surface 11. As shown in FIG. 3, when the folding door 1 is folded, the guide 7 of the first link 6 contacts the runner 5 a of the side end panel 2, and the end 6 a of the first link 6 contacts the wall surface 11. Therefore, the partition surface 2e of the side end panel 2 does not directly contact the wall surface 11.
[0010]
As shown in FIG. 4, the end 6 a of the first link 6 is always in contact with the wall surface 11 by the action of the first link 6 and the second link 10 even in the intermediate state from the folding of the folding door 1 to the folding. Therefore, the buffer member 2b of the side end panel 2 does not directly contact the wall surface 11. Moreover, since the 2nd link 10 is pivotally supported by the intermediate | middle panel 3 through the long hole 10c so that a movement to a longitudinal direction is possible, the operation | movement of the 1st link 6 and the 2nd link 10 is smooth. On the other hand, since the end portions 6a of the first links 6 always come into contact with the two folding doors 1 before the side end panel 2, the side end panels 2 do not come into contact with each other or overlap each other. Therefore, with this folding door contact prevention device, it is possible to prevent breakage of the folding door due to contact between the folding door and the wall surface or between adjacent folding doors in any state from the folding door to the folding. Inability to open and close due to overlapping of doors can be prevented.
