Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a folding door that can be stored by folding a panel that is suspended and supported from a hanger rail.
[0002]
[Prior art]
The folding door shown in FIG. 4 and FIG. 5 is supported by two hanger rails 1a and 1b so that the panels 2a and 2b and 2c and 2d are suspended through runners 3a to 3d. .
[0003]
The panels 2a and 2b are rotatably connected via a hinge part 4a, and the panels 2c and 2d are rotatably connected via a hinge part 4b. And if it pulls out between wall surface 5a, 5b in the state which extended panel 2a, 2b and the same 2c, 2d linearly, it will become a sliding door which partitions between wall surface 5a, 5b.
[0004]
Further, as shown in FIG. 5, when the panels 2a, 2b and 2c, 2d are rotated in a direction perpendicular to the hanger rails 1a, 1b and folded to one wall surface 5a side, the space between the wall surfaces 5a, 5b is almost the same. Fully open.
[0005]
Such a folding door is disclosed in Patent Document 1, for example.

[Problems to be solved by the invention]
In the above-described folding door, runners 3a to 3d are attached to the center portions in the width direction of the upper edges of the panels 2a to 2d, respectively, and supported suspended from the hanger rails 1a and 1b via the runners 3a to 3d. The
[0008]
Then, as shown in FIG. 5, when the panels 2a to 2d are folded, the panels 2a and 2b and 2c and 2d are shifted in the width direction by a dimension equal to the distance a between the hanger rails 1a and 1b. Suspended and supported.
[0009]
Therefore, when the panels 2a to 2d are folded, the panel folding dimension in the direction orthogonal to the hanger rails 1a and 1b increases, and the appearance is not preferable.
An object of the present invention is to provide a folding door capable of reducing the size of the folding and improving the aesthetic appearance.
[0010]
[Means for Solving the Problems]
According to claim 1, c Ngareru and it provided guide rails and two pairs on the floor surface corresponding, between the guide rail and the set of the hanger rail panel is supported, it is supported on the hanger rail Ryokumi panels, said along the hanger rail is pulled difference operably and rotatably supported, each panel supported on both sets of hanger rails, is rotated in the direction of Cartesian to the hanger rail in a possible and has been folded sliding door convolution, when the convolution of each panel which is supported on the hanger rail Ryokumi, so that each panel hanger rail Ryokumi is supported aligned in the width direction, rotation of the panel fulcrum is offset from the widthwise center of the panel.
[0011]
According to claim 2, wherein the pivot point is, only the offset half the distance in the width direction from the center of the hanger rail Ryokumi spacing of the panel.
According to claim 3, wherein the panels, the panel which moves along the same hanger rail, is rotatably connected via a hinge portion.
[0012]
According to claim 4, panel supported on one of the hanger rails are offset in the direction of the pivot point moves away from the hinge, the lower supported by the panel suspended along the other of the hanger rail, toward the hinge portion the pivot point is offset.
According to a fifth aspect of the present invention, a plurality of panels are supported between the hanger rail and the guide rail on the floor so that they can be operated in a sliding manner along both rails, and can be rotated. The folding fulcrum of the panel is centered in the width direction of the panel so that when the panel is folded, the panel is supported by being aligned in the width direction. The rotation fulcrum is offset from the center in the width direction of the panel by a distance that is ½ of the distance between the hanger rails, and the panel moves along the same hanger rail. A panel that is rotatably connected via a hinge part and supported by one hanger rail is offset in a direction in which the rotation fulcrum moves away from the hinge part, and the panel follows the other hanger rail. Panels suspended supporting Te, the rotary fulcrum toward the hinge portion is offset.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
1 to 3 show an embodiment of a folding door embodying the present invention. The same components as those in the conventional example will be described with the same reference numerals.
[0014]
On the hanger rail 1a, panels 2a and 2b are suspended and supported so as to be movable and rotatable via runners 6a and 6b. Moreover, the panels 2a and 2b are connected so that rotation is possible via the hinge part 4a.
[0015]
On the hanger rail 1b, panels 2c and 2d are suspended and supported so as to be movable and rotatable via runners 6c and 6d. Moreover, the panels 2c and 2d are connected so that rotation is possible via the hinge part 4b.
[0016]
As for the said panels 2a-2d, a guide shaft protrudes from the lower edge part, and the runner 9 is attached to the guide shaft, respectively. And the runner 9 can move in the guide rails 8a and 8b provided on the floor.
[0017]
The runner 9 is provided on a common vertical line with the runners 6a to 6d. Accordingly, the panels 2a to 2d are rotated using the runners 6a to 6d and the runner 9 as rotation fulcrums.
[0018]
A handle 7a is provided at the end of the panel 2a, and a handle 7b is formed at the end of the panel 2d. By operating the handle 7a, the panel 2a and 2b can be moved and rotated, and by operating the handle 7b, the panels 2c and 2d can be moved and rotated.
[0019]
The runners 6a and 6b are attached by being offset from the center in the width direction of the panels 2a and 2b. The runner 6a is offset by a distance a / 2 that is half the distance a between the hanger rails 1a and 1b in the direction away from the hinge 4a. The runner 6b is also offset by the same distance a / 2 in the direction away from the hinge portion 4a.
[0020]
The runners 6c and 6d are also attached by being offset from the center in the width direction of the panels 2c and 2d. The runner 6c is offset by a distance a / 2 that is half of the distance a between the hanger rails 1a and 1b in a direction approaching the hinge portion 4b. The runner 6d is also offset by the same distance a / 2 in a direction approaching the hinge portion 4b.
[0021]
In the folding door configured as described above, when the panels 2a and 2b and the panels 2c and 2d are stretched in a straight line, they are pulled out between the wall surfaces 5a and 5b to form a sliding door that partitions the wall surfaces 5a and 5b.
[0022]
Further, as shown in FIG. 1, when the panels 2a, 2b and 2c, 2d are rotated in a direction perpendicular to the hanger rails 1a, 1b and folded to one wall surface 5a side, the space between the wall surfaces 5a, 5b is almost the same. Fully open.
[0023]
At this time, since the runners 6a to 6d are offset from the center in the width direction of the panels 2a to 2d as described above, the panels 2a to 2d are suspended and supported without shifting in the width direction.
[0024]
With the folding door configured as described above, the following operational effects can be obtained. (1) The panels 2a and 2b and the panels 2c and 2d can be operated by pulling along the hanger rails 1a and 1b.
(2) When the panels 2a to 2d are folded, the panels 2a to 2d can be folded in a direction orthogonal to the hanger rails 1a and 1b. Therefore, the space between the wall surfaces 5a and 5b can be greatly opened during folding.
(3) The panels 2a and 2b can be folded at the hinge 4a. Moreover, the panels 2c and 2d can be folded by the hinge part 4b. Therefore, the convolution dimension in the direction orthogonal to the hanger rails 1a and 1b can be reduced during convolution.
(4) Since the runners 6a to 6d are offset in the width direction from the centers of the panels 2a to 2d, the panels 2a to 2d can be suspended and supported in a state where they are aligned in the width direction when folded. Therefore, the folding size in the direction orthogonal to the hanger rails 1a and 1b can be reduced during folding, and the aesthetics during folding can be improved.
(5) Each panel 2a-2d is supported by each runner 6a-6d and the runner 9 so that rotation is possible. Therefore, even if the runners 6a to 6d and the runner 9 are offset from the center in the width direction of the panels 2a to 2d, the panels 2a to 2d are not inclined when the panels are folded.
[0025]
The above embodiment can be modified as follows.
-It is good also as a structure which suspends and supports each panel from three or more hanger rails.
-It is good also as a structure which connects 3 or more panels in a hinge part.
[0026]
【The invention's effect】
As described above in detail, the present invention can provide a folding door capable of reducing the folding size and improving the aesthetic appearance.
