This extendable door Y is provided with a folding device 6 that forcibly folds the single door 2A at the end of the hanging base when the single door 2A at the hanging base side is moved to the hanging base 10 side. It is being This folding device 6 has an abutting member 27 provided on the top surface of the single door 2A at the end of the hanging base.
and an abutment member 30 provided on the second guide rail 41. The abutting member 27 on the upper surface of the single door 2A is formed in the same shape as the abutting member 23 of the bending regulating device 4, and is provided at a widthwise intermediate position on the upper surface of the single door 2A. This abutting member 27 has a door unit 2A at the end of the hanging base that is attached to the support shafts 11, 21.
When the second guide rail 41 is opened and closed by pivoting around the inner guard material 43 side of the second guide rail 41

In addition, when the door unit 2A at the end of the hanging base is completely closed, a portion of the large-diameter disk 29 provided at the upper end of the shaft body 28 is connected to the second guide rail. It is positioned so as to fit into the outer guard material 42 of 41. On the other hand, the contact member 30 is formed in the shape of a substantially triangular block, and is fixed on the outer guard member 42 of the second guide rail 41 at a position closest to the suspension side of the disk 29 of the abutting member 27. ing. That is, this abutting member 30 is located at a position closest to the hanging base 10 side of the disc 29 of the abutting member 27 when the door unit 2A at the hanging base side end is moved toward the side opposite to the hanging base. In addition, it is provided at a position where the disc 29 collides when the door unit 2A at the end of the hanging base is moved toward the hanging base 10.

This folding device 6 operates as follows. That is, from the closed state of the door 2A at the end of the hanging base (Fig. 6),
When the single door 2A is moved toward the hanging base 10 in the same posture, the disc 29 of the abutting member 27
The outer circumferential portion of the disc 29 abuts against the inclined surface 30a of the contact member 30, and when the door unit 2A is further moved toward the hanging base from that position, the disc 29 touches the corresponding contact member 30.
As a result, as shown in FIGS. 7 and 8, the single door 2A at the end of the hanging base is pushed out against its support shafts 11, 21.
It acts so that it is bent by a slight angle (for example, about 5 degrees) around the center.

In this embodiment, the telescoping door body 1 is suspended and supported by the first guide rail 3 provided at its upper part, but in other embodiments, for example, the first guide rail is It is also possible to install it on the ground and guide the telescopic door body from below. Further, the bending regulating device 4 for regulating the bending of each individual door may be configured, in addition to the above embodiment, to directly guide each individual door to an unbending state, for example. Furthermore, regarding the folding device 6, when the single door at the end of the hanging base is moved to the hanging base side, the folding device 6 forcibly folds the second single door from the hanging end or as described later. As long as it can be folded, any suitable structure can be used.

Next, the usage and operation of the foldable telescoping door Y of the first embodiment will be explained.

In the extended state of the extendable door unit 1, the individual door units 2A to 2F are lined up with each other in a straight line as shown in FIG. In the state shown in FIG. 6, the support shafts 11, 21 of the door unit 2A at the end of the hanging base are located near the opposite end 17a of the elongated hole 17 of the bracket 16 on the hanging base side. When opening the extendable door body 1 from this state, when the single door 2F at the end opposite to the hanging base is pressed toward the hanging base (in the direction of arrow A), each single door 2A to 2
Since F are lined up in a straight line, the entire extendable door main body 1 is moved linearly toward the hanging base 10 side. In addition, at this time, the support shafts 11, 21 of the single door 2A at the end of the hanging base
is the hanging base 1 in the elongated holes 17, 17 of the bracket 16.
It is moved to the 0 side. When the entire extendable door body 1 is moved toward the hanging base 10 side, the disc 29 of the abutment member 27 provided on the door unit 2A at the hanging base side end collides with the inclined surface 30a of the abutting member 30, and the corresponding Disc 2
9 is the corresponding contact member 3 as shown in FIGS. 7 and 8.
0, the door 2A at the end of the hanging end moves at a predetermined angle (for example, 5°) around the support shafts 11 and 21. (degree). Furthermore, during this telescoping door opening operation, each of the third and subsequent doors 2C to 2F from the hanging base of the telescoping door body 1 is within the range where the second guide rail 41 is provided by the bending regulating device 4. The second and subsequent hinge joints 12 counted from the hanging base side are unbendable inside.
The portions B to 12E are designed so that they do not protrude outward from the second guide rail 41 and are not bent. Then, from the state shown in Fig. 8, that is, the state in which the single door 2A at the end of the hanging base and the single door 2B at the second single door are bent into a "h" shape, the door at the end opposite to the hanging base is further bent. When the single unit 2F is pushed toward the hanging base, the first hinge joint 12A connecting the single door 2A at the end of the hanging base and the second single door 2B is directed toward the inside of the garage as shown by arrow R. The two doors 2A and 2B are folded as shown in FIG. 9. Moreover, as shown in FIG. 9, when the hanging end and the second individual doors 2A, 2B are folded,
The second door unit 2B is the first guide rail 3
The second door unit 2 is rotated around the support shaft 14 guided by the
Single third door 2C hinged to B
is rotated by a slight angle about the shaft body 24 of the abutment member 23. When the door unit 2F at the end opposite to the hanging base is further pushed toward the hanging base, the disc 29 of the third door unit 2C comes off from the end of the inner guard material 43, and the third door unit 2C becomes foldable. Then, if you continue to push the single door 2F at the end opposite to the hanging base, the 4th, 5th, and 6th single doors 2D, 2E, and 2F will also be pushed in the same way, relatively small near the hanging base. After being folded within the range, the entire telescoping door body 1 is finally folded open as shown by the chain line in FIG. When closing the opened telescopic door body 1, if you move the single door 2F at the end opposite to the hanging base to the opposite side (arrow B side), each single door 2A to 2F will be closed during the above opening operation. It operates and closes in the reverse order of operation. in this way,
In this folding telescopic door Y, when opening/closing the door, each of the individual doors 2A to 2F is folded only in a relatively small area on the hanging base side.
Compared to the folding and retractable door shown in Figure 6), the space that becomes unusable when opening and closing the door can be reduced.

Immediately before the closing of the extendable door body 1 is completed, each of the six individual doors 2A to
The 2Fs are temporarily lined up in a straight line, and when the door is further operated in the closing direction from this state, the entire extendable door body 1 moves linearly toward the side opposite to the hanging base. By the way, a locking device is usually attached to the free side end of the extendable door main body 1 so that the free end can be locked to a support on the side opposite to the hanging base when the door is closed. As described above, the entire telescopic door body 1 moves in a straight line in the range from the state immediately before completion of door closing to the state of completion of door closing, so that the locking operation of the free side end of the telescopic door main body 1 becomes easy. This effect can be obtained. In addition, with conventional folding telescoping doors, the free end of the door (to which the locking device is attached) pivots until the door is fully closed.
Lock operation was becoming troublesome.

In the foldable telescopic door Z of the second embodiment shown in FIGS. 10 to 15, the second guide rail 41A that constitutes a part of the bending regulating device 4
The third guide rail 41A is provided on the side of the first guide rail 3 (the side on the garage 8 side) that guides the The abutment members 23A, 23A provided on the fifth door units 2C, 2E are slidably fitted. In addition, this second guide rail 41A has a suitable position near the hanging base (hanging base 10).
When the door is opened, the abutment member 23
A direction change guide rail 45 is formed to guide the A and 23A outward toward the garage.

Further, the folding device 6 of the second embodiment forcibly folds the second door unit 2B from the hanging base side end when the door is opened. That is, in the folding device 6 of this second embodiment, the second
A disc-shaped abutment member 27 is provided on the top surface of the second door unit 2B.
A and the first guide rail 3
The abutting member 3 that the abutting member 27A abuts against the lower surface of the
0A is provided. The abutting member 27A and the abutting member 30A are arranged so that when the extendable door is closed, the abutting member 27A is located close to the abutting member 30A on the side opposite to the hanging base. When the entire main body 1 is moved toward the hanger side, the abutting member 27A abuts the abutting member 30A and folds into a mountain-fold shape toward the garage at the pivot joint (portion 12A). It is now possible to do so. In addition, even if the second door unit 2B counting from the hanging end is folded in this way, the first
As in the case of the embodiment, there is no possibility of bending outside the predetermined small range M on the hanging base side.

The rest of the structure of the foldable telescoping door of the second embodiment is substantially the same as that of the first embodiment, so the description of the folding telescoping door of the first embodiment will be referred to.

(Effects of the invention) The folding telescopic door of the invention has the following effects.

(a) Since the extendable door body 1 is configured such that each door unit 2A to 2F is folded only in a predetermined small area on the hanging base 10 side by the folding regulating device 4,
The space (dead space) that becomes unusable when the extendable door body 1 is opened and closed can be reduced.

(b) The single door 2A at the end of the hanging base is movable in the direction of opening and closing the telescopic door within the range of the elongated hole 17 on the side of the hanging base 10, and when the main body 1 of the telescopic door is operated in the opening direction. , since the folding device 6 forcibly folds the hanging end or the second single door 2A, 2B from the hanging end, for example, the single door 2F at the end opposite to the hanging end is folded. Each of the individual doors 2A to 2F can be sequentially folded by simply operating it toward the hanging base 10, and the opening operation of the extendable door body 1 can be performed easily and reliably.

(C) The single door 2A at the end of the hanging base is rotated about the supporting shaft 11 by inserting the support shaft 11 provided at the end of the hanging base into the elongated hole 17 on the hanging base 10 side. Therefore, in the case where the folding device 6 is made to function by making the door 2A at the end of the hanging side movable in the opening/closing direction of the telescopic door, the door 2A at the end of the hanging side can be moved freely. The door unit 2A itself can now be folded toward the hanging base 10, and the extendable door body 1
In the folded and open state, the folded telescoping door body 1 can be gathered at a position close to the hanging base 10. Therefore, in the open state of the telescoping door, the usable opening width becomes larger.
