[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 Utility Model Application Laid-Open No. 64-31871, 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. As a result, 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, the guide rod is fitted into the groove of the lower guide rail, and the door panel can be moved in the direction of expansion and contraction of the folding door along the upper guide rail and the lower guide rail. Supported by On the hanging side of the folding door, the hanging frame is fitted into the opening of the hanging pillar, is slidably supported in the opening and closing direction of the folding door, and prevents the swing of the door body panel on the hanging side. I have. During the opening operation, the suspension frame is slid within the suspension column, and the side end of the suspension frame is brought into contact with the inner wall of the suspension column and pressed. A component force is generated at a hinge portion connecting the door panel and the door body panel, and the component force acts in a direction of rotating the door body panel on the suspension side. Therefore, the reaction force obtained by bringing the end of the hanging frame into contact with the inner wall of the hanging pillar causes rotation of the door panel on the hanging side.

[0003]

However, in the conventional folding door, at the time of opening operation, the end of the hanging frame is slid inside the hanging pillar to abut on the inner wall of the hanging pillar. In this case, an unpleasant collision sound is generated, which is not preferable. In a long-term use, the impact force repeatedly applied may cause the door body to rattle. On the other hand, in order to prevent the above-mentioned inconvenience, at the time of opening the door body, slowly move the end of the door body side of the hanging frame to abut against the inner wall of the hanging pillar, and confirm that the abutting is performed. It suffices to apply force to the door body in the opening direction so that the end of the hanging frame pushes the inner wall of the hanging pillar, but this is poor in operability when the door body is folded.

[0004]

SUMMARY OF THE INVENTION In view of the above problems, the present invention folds and expands and contracts a door body in which a plurality of door body panels are rotatably hinged to each other along a guide rail provided at a door opening. The hanging frame of the door body is fitted to the hanging column so that it can slide in the door opening and closing direction, and the side end of the hanging frame is brought into contact with the inner wall of the hanging column when the door body is opened. In the foldable door to be brought into contact, a leaf spring is attached to one of the side end of the hanging frame and the inner wall of the hanging pillar in a vertically long shape. The intended problem has been solved by separating the side end of the hanging frame and the other of the inner walls of the hanging pillar from each other.

[0005]

According to the present invention, even when the side end of the hanging frame is slid vigorously toward the inner wall of the hanging column during the door opening operation, the side end of the hanging frame or the hanging portion of the hanging frame can be used. A leaf spring is attached vertically to one of the inner walls of the hollow part of the main column, so the impact force at the time of collision is absorbed and reduced by the leaf spring, so that the collision sound can be suppressed to a very low level, and the impact force produces backlash. Can be suppressed. Further, the pressing force for folding the door body acts without waste due to the reaction due to the elastic deformation of the leaf spring, so that the operability at the time of folding the door body is improved.

[0006]

1 to 5 show a first embodiment of a folding door according to the present invention, wherein a door body 1 can rotate a plurality of door panels 2, 2. So that they are hinged. The upper edge of the door opening 13 is provided with an upper guide rail 8 having a substantially U-shaped cross section. The door main body 1 is suspended so as to roll on the upper surface of the guide portion formed at the bottom. A lower guide rail 9 having a substantially U-shaped cross section is provided at a lower edge of the door opening 13, and a lower roller 7 is provided corresponding to a lower portion of the hinge member 3 provided with the hanger roller 6. It fits in the lower guide rail 9. Therefore,
The door body 1 has an upper guide rail 8 and a lower guide rail 9
It is supported so that it can be folded and stretched along.

[0007] A door stop frame 5 is provided on the door stop side of the door body 1, and is erected on the door stop side of the door opening 13 in a door closed state by a lock device incorporated in the door stop frame 5. It is possible to lock the door stop pillar 11. On the other hand, on the hanging side of the door body 1, there is provided a hanging frame 4 hingedly connected to the door body panel 2 near the hanging side, and the side end of the hanging frame 4 is used to suspend the door opening 13. Suspended suspension column 1 with a substantially U-shaped cross section, standing on the base side
0. An engaging member 42 is provided at a side end portion of the hanging frame 4, and an engaging piece 43 is formed integrally with the engaging member 42, and the engaging piece 43 is provided at the edge of the opening of the hanging pillar 10. It is configured to engage with the stopper member 103. Accordingly, the side end of the hanging frame 4 is slidably fitted in the opening and closing direction of the door body 1 inside the hanging pillar 10, and is prevented from coming off by the engagement of the engaging piece 43 and the stopper member 103. Have been.

At the side end of the hanging frame 4, an arc-shaped leaf spring 12 is provided.
Are provided in a vertically elongated shape with the engaging member 42 interposed therebetween. When the door body 1 is closed, the protruding tip 121 of the leaf spring 12 is provided to be separated from the inner wall 102 of the hanging column 10 to some extent as shown in FIG. In addition, this leaf spring 12 forms a screw hole etc. in the both ends,
It can be easily attached to the hanging frame 4 by screws or the like.

The operation of the foldable door having such a configuration will be described. First, when the door body 1 is in the closed state, the plurality of door panels 2 are arranged in a straight line as shown by the solid line in FIG. The door frame 13 of the door body 1 closes the door opening 13 in a state where the door stop frame 5 is in contact with the door stop pillar 11. Next, when the door main body 1 is moved in the opening direction to open the door opening 13, the hanging frame 4 moves in the inside 101 of the hanging pillar 10 in the door opening direction. Then, the protruding tip 12 of the leaf spring 12 provided on the hanging frame 4
1 comes into contact with the inner wall 102 of the suspension pillar 10, and the leaf spring 12 undergoes elastic deformation. At this time, the door body 1 is moved vigorously so that the distal end 121 of the leaf spring 12 is
Even if the collision occurs, the leaf spring 12 is elastically deformed, so that the collision sound can be extremely suppressed.

Further, when the door main body 1 is pressed in the opening direction, the leaf spring 1
Since 2 is elastically deformed by the collision force, the force of elastically deforming the leaf spring 12 directly acts as a reaction and acts as a force for pushing back the hanging frame 4. Then, the reaction force acts on a hinge portion formed integrally with the hanging frame 4 to cause the door panel 2 adjacent to the hanging frame 4 to rotate.
At this time, since the leaf spring 12 is attached to the hanging frame 4 in a vertically elongated shape, the entire width of the leaf spring 12 is not hung without the partial contact with the hanging pillar inner wall 102 in the width direction of the leaf spring 12. Since it abuts against the inner wall 102, the swing of the hanging frame 4 can be prevented, and the reaction of the leaf spring 12 acts on the hinge portion of the hanging frame. When the pressing is continued while maintaining the pressing state, the door panel 2 is sequentially folded from the hanging frame 4 side, and FIG.
The opening operation of the door opening 13 is completed as indicated by the two-dot chain line.

Although the engaging member 42 is formed separately from the hanging frame 4 in the above embodiment, the engaging member 42 may be formed integrally with the hanging frame 4, and the stopper member 103 may be integrally formed with the hanging column 10. May be formed. In addition, two leaf springs 12 are arranged side by side in the vertical direction of the hanging frame 4, but any number of leaf springs 12 may be provided as long as they are at least one or more.

FIG. 6 shows a second embodiment of the present invention, which differs from the first embodiment in that a leaf spring 12 is provided on the inner wall 102 of the hanging column 10, and other configurations and operations are performed. Is the same as in the first embodiment.

[0013]

According to the present invention, a leaf spring is attached to one of the side end of the hanging frame and the inner wall of the hollow of the hanging pillar, and the leaf spring is attached vertically when the door body is closed. Because the tip of the protruding part is separated from the side end of the hanging frame or the other of the inner walls of the hanging pillar, the impact force at the time of the collision is absorbed and reduced by the leaf spring, and the collision sound can be extremely suppressed. The occurrence of backlash due to impact force can be suppressed. Further, since the pressing force for folding the door body acts without waste due to the reaction due to the elastic deformation of the leaf spring, good operability is provided.
