[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foldable door for opening and closing a door opening by means of a door body hinged so that a plurality of door body panels are rotatable relative to each other.
In particular, it is useful as a door device, partition or the like of a building.

[0002]

2. Description of the Related Art As shown in, for example, Japanese Patent Application Laid-Open No. H2-125082, a hanger roller is attached to an upper end of a connecting device for connecting a plurality of door panels, and the hanger roller is suspended on an upper guide rail. Thereby, the folding door is held in a suspended state. On the other hand, a guide rod is attached to the lower end of the connecting device, and the guide rod is fitted into the groove of the lower guide rail. Therefore, the door panel is supported by the upper guide rail so as to be movable in the direction of expansion and contraction of the folding door, and by fitting the lower guide rail and the guide rod, the door panel is prevented from moving in the front-rear direction, and the upper panel is connected to the upper guide rail. The upper guide rail and the hanger roller are prevented from being deformed due to the swing of the door panel around the suspension portion of the hanger roller.

[0003]

However, in the conventional foldable door, since the groove of the lower guide rail is located in the floor of the door opening, it is difficult for a person to enter and exit. There is a possibility that a foot may be caught in the groove, or a foreign object may enter the groove, thereby impeding the smooth opening and closing operation of the folding door.

If the lower guide rail is eliminated, the above problem can be solved. However, there is no means for restricting the door panel from moving in the front-rear direction.
In particular, at the time of folding in the open state, the door panel is projected from the suspension between the upper guide rail and the hanger roller in one of the front and rear directions, so that the center of gravity of the folding door is displaced, and the weight of the folding door is reduced. Since it acts as a rotational force so as to fall in the direction protruding around the suspension part between the upper guide rail and the hanger roller, not only can it not be opened and closed smoothly, but also the upper guide rail or the hanger roller is deformed, It is hard to withstand use over a long period. On the other hand, it is conceivable to reinforce the upper guide rail and the hanger roller so as to withstand the rotational force, but this increases the cost and weight and is not suitable for mass production.

Furthermore, when the door stop frame is fitted into the recess of the door stop post during the closing operation of the folding door, the door stop end of the folding door swings back and forth around the guide rail and the suspension portion of the hanger roller. When this occurs, the door stop frame does not fit well into the recess of the door stop post, and the door stop frame and the end of the door stop post may collide and be damaged, thereby deteriorating the appearance of the folding door.

[0006]

Are hingedly connected to each other by a hinge member 5 so as to be rotatable with respect to each other. When the door opening 9 is closed, the door main body 1 closes the door opening 9 in a state where the door stop end 101 of the door main body 1 is fitted into the fitting recess 71 of the door stop post 7. In the closed state, the locking device 103 provided on the door stop frame 13 and the locking device 51 provided on the hinge member 5 restrict swinging of the door body 1 in the front-rear direction. On the other hand, in the opened state, the door body 1 is folded so that the door panel 2 is overlapped on the hanging pillar 8 to which the hanging end 102 of the door body 1 is connected, and the door opening 9 is opened.

A guide rail 3 having a substantially U-shaped cross section is provided at the upper edge of the door opening 9, and a pair of hanger rollers 4 provided on the upper part of every other hinge member 5 are connected to the guide rail 3. Guide part 31 integrally formed opposite to each other
It is suspended to roll on the upper surface. Accordingly, the door body 1 can be folded and stretched along the guide rail 3,
The door body 1 is supported by the guide rail 3 in a suspended state. One side wall 32 of the guide rail 3 has a seal mounting portion 34 up to a height located on the upper side of the door panel 2.
Is extended downward, and a seal member 35 is attached to the tip of the seal attachment portion 34.

On the upper part of the hinge member 5 to which the hanger roller 4 is not attached, the door panel 2 in the closed state is provided.
An anti-vibration roller 10 for preventing the vibration of the guide rail 3 is provided so as to be urged upward by a sprung or the like and to come into contact with the inner surface of the other side wall 33 of the guide rail 3. The swing-prevention roller 10 is pushed down by a slope or the like provided on the suspension column 8 side of the guide rail 3 during the opening operation of the door body 1, and is disengaged from the side wall 33 so that the inside of the guide rail 3 is released. And the door body 1 can be sequentially folded from the hanging end 102 side. The hanging frame 11 at the hanging end 102 of the door body 1 is slidably fitted in the hanging pillar 8 within the hanging pillar 8, and the swing of the door panel 2 closest to the hanging pillar 8. Has been prevented.

On the floor G, which is the lower edge of the door opening 9 on the hanging end 102 side, a door body fall prevention member 12 is provided.
The door body fall prevention member 12 supports a door body fall prevention roller 121 formed of resin or the like by a support shaft 122 so as to be rotatable in a horizontal direction, and a lower end of the support shaft 122 has a tubular member 1 embedded in a floor surface.
23, etc., are firmly fixed to the floor surface G by bolt nut means or the like. As shown in FIGS. 3 and 4, the door body fall prevention roller 121 of the door body fall prevention member 12 does not always protrude forward and backward from the position below the guide rail 3 when the door body 1 is folded and opened. The lower end of the side panel of the door body panel 2 and the lower end of the hinge member 5 located at the bent portion 104 on the side below the guide rail 3 are provided so that the peripheral surface of the door body stopper roller 121 abuts. . further,
The door body fall prevention rollers 121 are disposed such that one or two abutments are provided on the lower end of the side wall of the door body panel 2 and the lower end of the hinge member 5 of each bent portion 104. Note that the door body fall-prevention rollers 121 may be densely arranged with a small diameter, and three or more door body fall-prevention rollers may contact one bent portion. Further, since the door body fall prevention member 12 is provided at a position substantially below the guide rail 3, it can be constructed compactly.

A guide member 14 is provided on the floor G, which is the lower edge of the door opening 9 on the door stop end 103 side. The guide member 14 has a configuration similar to that of the door body stopper member 12, and a guide roller 141 formed of resin or the like is supported by a support shaft 142 so as to be rotatable in the horizontal direction.
Numeral 2 is fixed to the floor surface G. This guide member 1
The fourth guide roller 141 has a door stop frame 13 and a door stop pillar 7.
The door stop frame 1 is fitted so that it fits into the fitting concave portion 71 at a regular position.
The guide roller 141 is disposed at a position where the peripheral surface of the guide roller 141 contacts the side wall of the third roller 3. Preferably, if a pair of guide rollers 141 are provided in the front-rear direction of the door body, the swinging of the door stop frame 13 in the front-rear direction can be reliably prevented and guided, but the door panel 2 in this embodiment is not shown. As shown in FIG. 3, from the suspension of the guide rail 3 and the hanger roller 4,
The door body 1 is biased and connected to the left in the drawing.
Due to the weight of the door panel 2, a force is applied to rotate the guide rail 3 and the hanger roller 4 in a counterclockwise direction around the suspension portion thereof, and a relatively large swing in the counterclockwise direction is generated. Therefore, in this embodiment, one guide member 14 may be provided at least at a position where the swinging in the counterclockwise direction can be prevented (a position below the right side surface of the door panel 2 in FIG. 3).

[0015] Next, the operation of the folding door consisting of such a configuration. First, in the closed state of the door main body 1, the plurality of door body panels 2 are extended in a straight line via the hinge member 5 as shown by a solid line in FIG. When the door is locked, the door main body 1 cannot be folded by the lock device 103 provided at the door stop end 101 and the lock 51 provided at the lower end of the optional hinge member 5.

Next, release the respective lock, move the door body 1 by such a handle provided on the doorstop end side 101 to Tsumotohashira 8 side, first, Tsumoto stile 11 Tsumotohashira within 8 Slide in,
Next, the door main body 1 is sequentially folded from the hanging end 102 side.
Door body 1 located below guide rail 3 when folded
The lower end of the side of the door body panel 2 and the lower end of the hinge member 5 in the bent portion 104 move toward the hanging post 8 while contacting the peripheral surface of the door body stopper roller 121 of the door body stopper member 12. At this time, since the door body fall-preventing roller 121 is supported by the support shaft 122 so as to be rotatable in the horizontal direction, the rotation of the door body fall-prevention roller 121 causes the door body fall-preventing roller at the time of opening and closing the door body 1. The contact resistance between the door 121 and the door panel 2 and the hinge member 5 is extremely small and does not hinder a smooth opening and closing operation.

The lower end of the side of each door body panel 2 and the lower end of the hinge member 5 in each bent portion 104 located below the guide rail 3 are in contact with the door body fall-preventing roller 121, so that they can be moved in the front-rear direction. The hinge members 5 to which the door body panels 2, 2... And the hanger roller 4 are not attached protrude, so that the center of gravity of the door body 1 is displaced, and the weight of the door body 1 causes the suspension of the guide rail 3 and the hanger roller 4 to move. Even if rotational force acts so that it falls in the direction protruding as the center,
.. And the hinge member 5 to which the hanger roller 4 is not attached, against the rotational force, so that the guide rail 3 and the hanger roller 4 are supported.
No swing occurs in the front-rear direction around the suspension portion of the vehicle.
Then, as shown by the two-dot chain line in FIG. 2 , the folding of the door main body 1 is completed.

Next, in order to again closed state the door opening 9, when the doorstop end 101 of the door body 1 has a open state is moved toward the doorstop pillars 7, doorstop end 101 , The door body 1 is sequentially extended, and the door opening 9 is closed. Then, the door stop frame 13 is inserted into the fitting recess 71 of the door stop post 7.
When the door stop frame 13 is slightly swung in the front-rear direction, the door stop frame 13 abuts on the peripheral surface of the guide roller 141 of the guide member 14 and is guided. To fit into the fitting recess 71 of the door stop post 7. At this time, since the guide roller 141 is supported by the support shaft 142 so as to be rotatable in the horizontal direction, the rotation of the guide roller 141 causes the contact between the guide roller 141 and the door stop frame 13 when the door body 1 is closed. The resistance is very small.

[0019]

According to the present invention, when the door is folded, the door is prevented from swinging in the front-rear direction due to its own weight in the horizontal direction.
Since the door body fall prevention member composed of a rotatably supported roller is provided at the lower edge of the door opening so as to abut against the lower end of each bent part of the door body, the door body panel is guided by the guide rail in the folded state of the door body. By projecting from the lower position in the front-rear direction, the position of the center of gravity of the door body is displaced, and the rotation force in the front-rear direction is such that the weight of the door body falls down in the direction protruding around the guide rail and the suspension portion of the hanger roller. When the door body falls down, the door body fall prevention member abuts on the lower end of the bent portion located below the guide rail of the door body, so that the door body is supported against the rotational force of the door body and the guide rail is supported. Alternatively, a smooth opening / closing operation is provided for a long period without causing deformation of the hanger roller.

Further, since it is configured door body collapse preventing member by rotatably supported roller horizontal direction, even if the contact roller to the lower portion of the door body when the opening and closing operation, the frictional resistance can be reduced as much as possible And a smooth opening and closing operation can be provided.

Furthermore, low-rotatably supported in a horizontal direction for guiding the doorstop stile of the door body into the mating recess of the door per column
Since the guide member made of a rubber door is provided at the lower edge of the door opening, when the folding door is closed and the door stop frame is fitted into the recess of the door stop pillar, the door stop end of the folding door has the guide rail and the hanger roller. The door stop frame is guided by the guide member and fits into the fitting recess of the door stop column even if the door stop frame swings in the front-rear direction about the suspension portion of the door stop. It is possible to prevent the parts from colliding and being damaged, and to provide a folding door having a good appearance over a long period of time.

Further, since it is configured to guide member by a rotatably supported roller horizontal direction, even if it contacts the roller at the bottom of the doorstop stile, the frictional resistance can be reduced as much as possible, a smooth opening and closing operation is provided You can do it.
