DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding door provided at an opening of a building or the like.

[0002]

2. Description of the Related Art In recent years, with the diversification of building designs, for example, a plurality of panel bodies connected in series are alternately arranged in an opening such as a living room, a reception room, or a bay window. In some cases, folding doors are provided which are folded and stored in a zigzag shape. By the way, such a folding door, when the panel body is folded and housed, is folded from an attitude that is flush when opening and closing the opening to an alternate zigzag attitude that is folded and housed. At this time, it is absolutely necessary to secure a space for the panel body to fold and swing as a storage space. This folding swing space does not pose a problem in the middle of storage because there is still enough room in the storage depth, and this folding swing transformation is performed for a pair of panel bodies folded and stored in the last round. It was necessary to secure a space for the operation, which was a factor that hindered the downsizing of the storage unit.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and aims to provide a folding door capable of eliminating these disadvantages.
In a folding door configured to store a plurality of panel bodies connected in series in a zigzag pattern alternately, a pair of panel bodies that are folded and stored at least in the last round of the panel bodies One of the panel body,
The panel body is configured to be bent so as to be bent in a mountain shape at an intermediate portion in the width direction of the panel body.

According to the present invention, the space of the storage section of the folding door can be reduced by this configuration.

[0005]

Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a folding door to be built at an opening of a building. The folding door 1 folds the upper and lower side edges of a plurality of panel bodies 2 alternately in a zigzag manner via a connecting member 3. The guide member 4 and the auxiliary roller 5 are attached to every other left and right end portions of the connecting member 3.
Reference numeral 6 denotes guide rails provided on both right and left sides of the opening. The guide rails 6 include a main rail 6a for guiding the guide roller 4 and an auxiliary rail for guiding the auxiliary roller 5. 6b, the main and auxiliary rails 6a and 6b are
The main rail 6a extends linearly into the storage case 7 provided above the opening. Reference numeral 8 denotes a drive motor provided in the storage case 7, and a pair of right and left take-up pulleys 9 are operatively connected to the drive motor 8, and a wire wound around the take-up pulley 9 is provided. The lower end of 10 is fixed to the lowermost first panel body 2A described later. Then, the wire 10 is wound and rewound by the forward and reverse rotation of the winding pulley 9 accompanying the driving of the motor, whereby the panel bodies 2 are flush with each other at the opening. The opening portion is opened and closed by moving up and down in a posture in which the plate portions are alternately zigzagly arranged in the storage case 7.

The first panel body 2A is the last of the pair of panel bodies 2 folded and stored at the last time.
Is stored at the bottom, that is, the lowermost panel body,
2B is a second panel body stored before the first panel body 2A, that is, the second panel body stored from the last,
In the first embodiment shown in FIG.
B implements the present invention. In other words, when the second panel body 2B has a bent portion 2b formed in an intermediate portion and is stored in the storage case 7, the second panel body 2B is closed at the entrance side of the storage case 7 (in FIG. Side) to be bent and protruded in a mountain shape.

Further, in the second embodiment shown in FIG. 3, the present invention is applied to the second panel body 2B as in the first embodiment. The body 2B is configured to be bent so as to be bent in a mountain shape and protrude toward the opposite side (the right side in FIG. 3) of the main rail 6a at a bent portion 2b formed at an intermediate portion thereof.

In the third embodiment shown in FIG. 4, the present invention is applied to the first panel body 2A. This embodiment is folded at an intermediate portion of the first panel body 2A. A bent portion 2a is formed, and when stored in the storage case 7, the bent portion 2a bends in a mountain shape toward the back side (upper side in FIG. 4) of the storage case 7 so as to protrude freely. It is configured.

When considering each of these embodiments, as shown in FIG. 6, as an extension of the third embodiment, the bent portion 2a formed at the intermediate portion of the first panel body 2A is connected to the entrance side of the storage case 7 ( It is also conceivable to bend in the shape of a mountain (to the lower side in FIG. 6), and this will be used in the following description as a comparative example.

In each of the embodiments of the present invention configured as described above, the trajectory when the panel body 2 is stored in the storage case 7 has no bent portion (shown in FIG. 7) and the comparative example. Compare using trajectories. With respect to each of these trajectories, when the panel body 2 is stored in the storage case 7, each of the embodiments in which the present invention is implemented has a folded shape as compared with the case without the bent portion and the comparative example. It is recognized that the swing trajectory has become smaller. This is the bent part 2a
Alternatively, the first panel body 2A or the second panel body 2B on which the 2b is formed is caused to be folded in the storage case 7 in connection with the swinging movement, and as a result,
The folding swing space in the storage case 7 can be made smaller by that amount, and the space of the storage case 7 can be reliably reduced in size.

It should be noted that the present invention is not limited to the above-described embodiments, and is not limited to a pair of panel bodies which are folded and stored at the last time. The present invention may be applied to a pair of panel bodies to be stored, or to panel bodies of all times. Further, the bent portion formed on the panel body does not need to be at the center, and may be deviated to any one, or may be bent at plural positions. Further, as shown in FIG.
The first panel body 2A and the second panel body 2B have bent portions 2
A fourth embodiment in which a and 2b are formed may be used. Furthermore, the present invention is not limited to the panel body that opens and closes in the vertical direction, but may be one that opens and closes in the horizontal direction, and can be widely applied to folding doors that are folded and stored in an alternating zigzag shape. Incidentally, when the panel body 2 is stored in the upper storage case 7 as in the embodiment, if the stopper 11 is provided as shown in FIG. 8, the panel body 2 can be smoothly fed out of the storage case 7. Can be.

[0012]

In summary, since the present invention is constructed as described above, the panel body is stored in the storage case in a state of being alternately zigzag folded.
Of these panel bodies, at least one of the pair of panel bodies that is folded and stored at the last time is linked to the folding swing of the panel body when the panel body is stored in the storage case. It becomes bent at the middle part. As a result, the folding swing space in the storage case can be reduced by that much, and the space of the storage case can be reliably reduced.
