Detailed Description of the Invention

[0001]

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

[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 in an alternating manner in an opening such as a living room, a reception room, or a bay window. A folding door may be provided for folding and storing in a zigzag shape. By the way, such a folding door can be folded from a flat shape when opening and closing the opening when the panel body is folded and stored to an alternating zigzag posture where the panel body is folded and stored. Although it will be rocked and transformed, at this time, it is necessary to secure a space for the panel body to be folded and rocked and transformed as a storage space. This folding swing space is not a problem at the stage of storage because there is still enough storage depth, and this folding swing transformation is performed for the pair of panel bodies that are folded and stored at the final round. It was necessary to secure a space for the operation, which was a factor that hindered the miniaturization of the storage section.

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 a folding door configured to fold and store a plurality of panel bodies connected in series in an alternating zigzag shape, among the panel bodies, a pair of panel bodies that are folded and stored at least at a final time. One of the panel body,
It is characterized in that it is configured to be bendable 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 portion of the folding door can be reduced by this structure.

[0005]

An embodiment of the present invention will be described below with reference to the drawings. In the drawing, reference numeral 1 denotes a folding door installed in an opening of a building, and the folding door 1 folds the upper and lower side edge portions of a plurality of panel bodies 2 through a connecting member 3 in an alternating zigzag shape. It is configured to be movably connected, but a guide roller 4 and an auxiliary roller 5 are attached to the left and right ends of the connecting member 3 every other one.
Reference numeral 6 denotes guide rails provided upright on both left and right sides of the opening. The guide rails 6 are a main rail 6a for guiding the guide roller 4 and an auxiliary rail for guiding the auxiliary roller 5. Although it has a double structure consisting of 6b and 6b, the main and auxiliary rails 6a and 6b have a storage case 7
Are provided side by side in parallel with each other, and the main rail 6a extends linearly into the storage case 7 provided above the opening. A drive motor 8 is provided in the storage case 7. A pair of left and right take-up pulleys 9 are linked to the drive motor 8. The wire wound around the take-up pulley 9 is connected to the take-up pulley 9. The lower end of 10 is fixed to the lowermost first panel body 2A described later. Then, the wire 10 is wound and unwound by the forward and reverse rotations of the winding pulley 9 associated with the motor drive, whereby the panel body 2 is flush with the plate surface portion of each panel body 2 at the opening. In the storage case 7, the plate parts are folded and stored in the storage case 7 in an alternating zigzag shape.

The first panel body 2A is the last storage case 7 of the pair of panel bodies 2 folded and stored at the final time.
Stored in, that is, the panel body at the bottom,
2B is a second panel body that is stored prior to the first panel body 2A, that is, the second panel body that is second from the last,
In the first embodiment shown in FIG. 2, the second panel body 2
The present invention is implemented in B. That is, the second panel body 2B has a bent portion 2b formed at an intermediate portion thereof, and when the second panel body 2B is housed in the storage case 7, the second panel body 2B is accommodated at the storage case 7 inlet side (lower side in FIG. It is configured to be bendable so as to fold and project in a mountain shape toward the side).

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

In the third embodiment shown in FIG. 4, the present invention is applied to the first panel body 2A, which is folded at the intermediate portion of the first panel body 2A. The bent portion 2a is formed so that when the bent portion 2a is stored in the storage case 7, the bent portion 2a can be bent so as to be bent in a mountain shape toward the back side (upper side in FIG. 4) of the storage case 7 to project. It is configured.

When considering each of these embodiments, as shown in FIG. 6, the bent portion 2a formed in the intermediate portion of the first panel body 2A is extended from the third embodiment to form the bent portion 2a on the inlet side of the storage case 7 ( It may be possible to fold it in a mountain shape toward the bottom (in FIG. 6), and this will be used as a comparative example in the following description.

Regarding each embodiment of the present invention constructed as described above, the locus when the panel body 2 is housed in the housing case 7 has no bent portion (shown in FIG. 7) and the above-mentioned comparative example. Compare using trajectories. Regarding each of these loci, when the panel body 2 is housed in the housing case 7, the embodiment of the present invention is folded as compared with the one without the bent portion and the comparative example. It can be seen that the rocking trajectory is becoming smaller. This is the bent portion 2a
Or, it is caused by the fact that the first panel body 2A or the second panel body 2B on which 2b is formed is linked to the folding swing in the storage case 7 and is bent.
The folding and swinging space in the storage case 7 can be made smaller accordingly, and the space for the storage case 7 can be surely reduced in size.

It should be noted that the present invention is not limited to the above-mentioned embodiments, but is not limited to the pair of panel bodies that are folded and stored in the final round, and is folded in the preceding round. The present invention may be applied to a pair of panel bodies to be housed and further to all panel bodies. Further, the bent portion formed on the panel body does not have to be at the center, and may be biased to either one, or of course, may be bent at a plurality of positions. Furthermore, as shown in FIG.
The bent portion 2 is formed on the first panel body 2A and the second panel body 2B.
It may be the same as the fourth embodiment in which a and 2b are formed. Further, the present invention is not limited to the one in which the panel body is opened and closed in the vertical direction, and may be the one that is opened and closed in the horizontal direction, and can be widely applied to folding doors that are folded and housed in an alternating zigzag shape. Incidentally, in the case where 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 drawn out from the storage case 7. You can

[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 folded in an alternating zigzag shape.
Of these panel bodies, at least one panel body of the pair of panel bodies that is folded and stored at the final time is connected to the folding swing of the panel body when the panel body is stored in the storage case. At the middle part, it will be bent into a mountain shape. As a result, the folding swing space in the storage case can be made smaller by that amount, and the space of the storage case can be surely reduced.
