Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding door that can be folded in a zigzag shape.

[0002]

BACKGROUND OF THE INVENTION Generally,
In this type of folding door, adjacent door bodies are connected in a zigzag manner via a connecting portion, and such a folding door is curved with respect to a curved guide rail laid on the body side. It may be built so that it can be folded and stored on the inner circumference side. In this structure, among the connecting portions, not the first connecting portion provided with the traveling roller but the second connecting portion provided alternately with the traveling roller is folded toward the curved inner circumferential direction of the guide rail when folded and stored. That is, it is stored in a state of protruding in the inner peripheral direction.

However, the second connecting portion, which is folded in the curved inner circumferential direction, is in a state along the guide rail when the door is closed, and in this state, the second connecting portion is pushed to the rear side of the door to store the folding door. At this time, the second connecting portion is not folded due to the load acting in the direction of bending to the outer peripheral side rather than the inner peripheral side. For this reason, conventionally, a person pushes the second connecting portion toward the inner peripheral side to fold it, but the work is very troublesome and complicated. Therefore, a guide member on the skeleton side and a guide receiving portion on the door body side are provided so as to be often used for a normal folding door that opens and closes along a straight guide rail that is not curved, and the guide receiving portion at the time of folding storage. It may be possible to force the folding by contacting the guide member, but in this one, since the guide receiving portion is provided in the vicinity of the second connecting portion, the first receiving member in the state along the outer peripheral side is formed. In order to fold the two connecting parts to the inner peripheral side, the guide receiving part or the guide member must be largely projected, but the guide receiving part is hidden on the outer peripheral side integrally provided on the guide rail. In reality, the guide member cannot be made larger than it is in contact with the roller bracket, and as a result, there is a problem that it cannot be implemented with a guide rail having a large curvature or a door body having a large width. .

SUMMARY OF THE INVENTION The present invention was devised with the object of providing a folding door capable of eliminating these drawbacks in view of the above-mentioned circumstances.
In folding and storing a folding door configured by connecting adjacent door bodies in a zigzag manner via a connecting portion so as to be folded and stored on a curved inner peripheral side with respect to a curved guide rail laid on the body side, The connecting portion has a first connecting portion provided with a traveling roller that is movably guided by the guide rail, and a second connecting portion that is foldable so as to project toward the curved inner peripheral side of the guide rail, and are alternately arranged. In addition, the guide receiving portion for contacting the guide member provided on the body side and forcibly pushing the second connecting portion to the curved inner peripheral side as the folding door is moved to the door tail side to be housed. Is biased toward the first connecting portion side of the door body and is provided at a position far from the second connecting portion.

According to the present invention, the folding door built on the curved guide rail can be smoothly and surely folded and stored by this structure.

The folding door 1 can be moved toward the door tail side by a predetermined stroke L from the position when the folding door 1 is fully closed. A traveling roller 7 is provided on the upper end of the door end side vertical frame 11 via a bracket 7a.

Further, at the lower part of the guide rail 5,
Although the door body concealment 5a that covers the outer peripheral side and the inner peripheral side of the upper end of the folding door 1 is integrally formed, the door body concealing 5a on the inner peripheral side is a door butt where the folding door 1 is folded and stored. The part on the side is cut out. A guide member 13 having an inclined guide surface 13a is provided at an appropriate portion of the door concealment 5a on the outer peripheral side so as to project toward the curved inner peripheral side of the guide rail 5. On the other hand, of the door body 2, the first connecting portion 3 or the door sill side vertical frame 11 is connected to the door butt side, and the second connecting portion 4 is connected to the door tip side. Is the first connecting portion 3

The guide receiving portion 1 having an inclined guide surface 14a at a position far from the connecting portion 4
4 is projected rearward, that is, toward the curved outer peripheral side of the guide rail 5. The guide receiving portion 14 is not in contact with the guide member 13 in the fully closed state of the folding door 1, but when the door body 2 is moved to the door butt side to store the folding door 1, the guide receiving portion 14 is guided. The part 14 contacts the guide member 13 and the door body 2
The second connecting portion side end of the guide rail 5 is pushed toward the curved inner peripheral side of the guide rail 5, whereby the second connecting portion 4 is moved to the guide rail 5 side.
It is set so that it is forcedly pushed to the inner circumference side of the curve.

In the embodiment of the present invention configured as described above, the folding door 1 is in the state of following the curve of the guide rail 5 in the fully closed state, but the folding door 1 in the fully closed state is folded and stored. When the door body 2 is moved to the side of the door,
Along with this, the guide receiving portion 14 provided on the door body 2 side abuts the guide member 13 provided on the body side, and the second connecting portion 4 is forced toward the curved inner peripheral side of the guide rail 5. Will be pushed.

As described above, in the embodiment of the present invention, when the folding door 1 is stored, the guide receiving portion 14 on the side of the door body 2 contacts the guide member 13 on the side of the body, so that The two connecting portion 4 is forcibly pushed to the curved inner peripheral side of the guide rail 5, whereby the folding door 1 can be folded smoothly and surely. In this case, the guide receiving portion 14 is provided. Is the first connecting portion 3 of the door body 2 or the vertical frame 11 on the door-end side
It is biased to the side and is provided at a position far from the second connecting portion 4. As a result, the guide member 13 and the guide receiving portion 1
The amount of movement of the door body 2 in the guide rail curve inner circumferential direction at the end portion on the second connecting portion side of the door body 2 is larger than the amount of pushing of the door body 2 in the portion abutting with 4. Even if the guide rail 5 has a large bending rate or the door body 2 has a large width, the guide member 13 and the guide receiving portion 14 do not protrude much more greatly, and the guide rail 5 can be folded and stored in the second direction. Since the connecting portion 4 can be reliably pushed in the curved inner circumferential direction of the guide rail 5, the reliability can be increased. By the way, the guide receiver 1
Since the second connecting portion 4 moves to the curved inner peripheral side of the guide rail 5 as it is provided closer to the first connecting portion 3 of the door body 2, the fourth connecting portion 4 moves as much as possible.
It is preferable to provide it at a site close to.

It should be noted that the present invention is not limited to the above embodiment, and in the first embodiment, the first connecting portion 3 or the door sill side vertical frame 11 is connected to the door sill side, and Although the guide receiving portion 14 is provided in the door body 2 in which the two connecting portions 4 are connected to the door tip side, the guide receiving portion 1 is provided as in the second embodiment shown in FIG.
4, the first connecting portion 3 is connected to the door end side, and the second connecting portion 4
Can be provided on the door body connected to the door butt side. Also in this case, by providing the guide receiving portion 14 at a position distant from the second connecting portion 4 by being biased toward the first connecting portion 3, the same effect as that of the first embodiment can be obtained. Further, even in the case where the door end side vertical frame 11 is not provided, the door body 2 arranged closest to the door buttocks side can be moved to the door buttocks side more than the position of the door body 2 when the folding door is fully closed. If configured, it can be implemented in the same manner. Further, the guide member 13 provided on the body side is provided at a portion where all the guide receiving portions 14 abut in the moving process when the door body 2 is moved to the door butt side to close the folding door 1. If one is provided, one is sufficient, but if not, a plurality may be provided at appropriate sites. Furthermore, the guide rails embodying the present invention are not limited to arc-shaped guide rails as in the first and second embodiments, but L-shaped guide rails with curved corners, and intermediate portions in opposite directions. The present invention can be applied to guide rails of various shapes such as a curved S-shape.

Further, in the first embodiment, the first connecting portion is formed by using the connecting member, and the second connecting portion is formed by using the main connecting member and the pair of left and right auxiliary connecting members. As shown in the third embodiment of FIGS. 9 to 11, both the first and second connecting portions 3 and 4 can be configured by using the main connecting member 18 and the auxiliary connecting member 19. Furthermore,
As shown in the fourth embodiment of FIG. 12, the first and second connecting portions, the main connecting member, and the intermediate member 15 into which the traveling roller mounting bracket 7a can be incorporated, and the intermediate member 1
5, a pair of pivotally supporting members 16, 17 in which pivotally supporting shafts 16a, 17a are detachably assembled from both side surfaces and pivotally pivotally support the end edge of the door body. May be formed by using, and in this case,
The folding door can be split and hung on the guide rails, and it can be partially repaired after the folding door is installed.
In the case of replacement or the like, the door body can be disassembled and removed from the folding door built in units of one piece, and the maintenance is greatly improved.

By the way, when the guide member on the frame side and the guide receiving portion on the door side are provided in a folding door built on a linear guide rail, the guide receiving portion is biased to the first connecting portion side. It is not necessary to provide it at a position distant from the second connecting portion, and the guide receiving portion 14 may be integrally fixed to the upper portion of the second connecting portion 4 as shown in FIG. 13, for example.

[0018]

In summary, since the present invention is constructed as described above, in the fully closed state, the folding door is along the curve of the guide rail. As the door is moved to the rear side for storage, the guide receiving part on the door side contacts the guide member on the body side, and the second connecting part is forced to the curved inner peripheral side of the guide rail. By pushing it, the folding door can be smoothly and surely folded by this, but in this case, the guide receiving portion is biased toward the first connecting portion side of the door body and is not from the second connecting portion. It will be installed at a distant position. As a result, the guide rail curved inner circumference at the second connecting portion side end portion of the door body is greater than the pushing amount of the door body in the guide rail curved inner circumferential direction at the contact portion between the guide member and the guide receiving portion. Even if the guide rail or the guide receiving part is not particularly protruded even when the guide rail or the door body has a large bending ratio or a large door body width, it can be folded and stored. Since the second connecting portion can be reliably pushed in the curved inner circumferential direction of the guide rail, the reliability can be increased.
