DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail with reference to the accompanying drawings. In FIGS. 1 to 5, A denotes a telescopic door, and 1 denotes a door parallel to the opening and closing direction of the telescopic door A. The arranged door body constituting bar 3 is a link device for expanding and contracting the door body constituting bar 1, and the link device 3 is rotatably supported at one end with respect to the door body constituting bar 1 or is slidable. A plurality of link bars 4 freely engaged with each other;
And a link connecting member 5 that rotatably supports the other end of the link bar 4 and connects the link bar 4 between the door body bars 1 so as to be able to expand and contract.

In other words, the telescopic door body A of this embodiment is installed at the opening as a see-through vertically extending shutter that expands and contracts vertically by the guidance of the left and right guide rails 14, for example, while the link device 3 is opened and closed in the opening and closing direction. The link device 3 is arranged between the adjacent door body component bars 1 so that the door device component bar 1 on which the link device 3 is arranged can be individually extended and contracted individually. By arranging a plurality of or more in the longitudinal direction of the door-constituting bar 1, the above-described individual expansion and contraction is performed in the longitudinal direction of the door-constituting bar 1 by using the adjacent door-constituting bar 1 as a unit of expansion and contraction, that is, a unit of opening and closing. Simultaneously, the telescopic door A can be stably opened and closed.

In the present embodiment, each of the door body constituting bars 1 is constituted by a single bar, and by arranging a large number of such bars in a horizontal manner, they are arranged in parallel with the opening / closing direction to form a telescopic unit. At this time, the link device 3 of the present example
Are arranged between the adjacent door component bars 1, respectively, and at the rear side position of the front side position and the rear side position of the door body component bar 1.

In the present embodiment, four link bars 4 of the link device 3 are used, and one of them is rotatably supported or slidably connected to the adjacent door-forming bar 1 at one end thereof. At this time, two of the four are rotatably supported on the shaft and the two are slidably engaged with each other. The rotatable shaft is supported by fixing the link bar 4 rotatably via the fixed shaft 10, and the slidable engagement is performed by the movable shaft 11 mounted on the link bar 4. In this embodiment, the movable shaft 11 is provided with an appropriate movable member 12 such as a roller, a slider, or the like at the tip of the door body constituting bar 1 on the side thereof. The movable member 12 is fitted to a guide member 2 formed on the back side of the door body bar 1 such as a C-shaped groove or an inverted T-shaped ridge, and is hooked and locked. The sliding movement can be performed smoothly and reliably.

The four link bars 4 are rotatably supported at the other ends of the link connecting members 5 so that the link device 3 which can be expanded and contracted between the door component bars 1 is connected. In this example, the link device 3 has an X-shape.

The link connecting member 5 of the present embodiment is formed, for example, in a circular shape as shown in the drawing, so as to provide a decorative accent in the X-shaped link device 3, and in the present embodiment, the link connecting member 5 has a circular shape. The link connecting member 5 is formed with a pair of shaft supporting members 6 in the opening and closing direction, and is connected to the pair of shaft supporting members 6 by a rotatable connecting portion, thereby connecting the link connecting member 5 back and forth. This allows the link connecting member 5 to rotate and bend in the link device 3 and allows the linking member 5 to extend and retract when the telescopic door A is opened and closed. Performs conversion, and bends or opens and closes the elastic door body A on a curved surface or a plurality of intersecting surfaces;
In this example, such as winding storage, cross storage is made possible.

At this time, the rotatable support of the link bar 4 by the link connecting member 5 of this embodiment is connected to each link bar 4 between the door-forming bars 1 arranged in parallel with the opening and closing direction.
The hinges 9 are used to connect at least a quarter circle to one of the front and rear sides using the hinge 9. Alternatively, in both cases, the operation is performed toward one of the back sides.

That is, the shaft support member 6 of the present embodiment is configured as an upwardly U-shaped section having opposed plates 8 before and after forming a link receiving groove 7 for receiving an end of the link bar 4, for example. By providing the hinge 9 on the back side between the walls, the link connecting member 5 constitutes a connecting member constituting the link connecting member 5.
The two link bars 4 from each of the door component bars 1 are respectively received in the respective link receiving grooves 7, and the link bars 4 are rotated in the link receiving grooves 7 when the link bars 4 are expanded or contracted. In this case, the pivotable pivoting is performed by fixing the link bar 4 via the fixed shaft 10 so as to be pivotable in the same manner as described above.

FIGS. 6 to 12 show another example. FIGS. 6 to 12 show a frame by providing a pair of door-forming bars 1 at the front and back, and arranging bar connecting members at both ends in the longitudinal direction. In the same manner as above, two link bars 4 are rotatably pivotally supported or slidably engaged with the front and rear door component bars 1 adjacent to each other in the opening and closing direction in the same manner as described above. Thus, a total of eight link bars 4 are used, and a rotatable support of the link bar 4 by the link connecting member 5 at the intermediate position between the front and rear door body bars 1 is provided between the front and rear door body bars 1. This is an example in which four doors are similarly stretched so as to be individually and monotonically expanded and contracted by linking the link devices 3 having the same X-shape by arranging the four bars in the same plane. Time link connecting member 5 The pair of shaft support members 6 are formed in an elliptical or short shape so as to eliminate mutual contact when the link device 3 is reduced and folded, and are provided with wide link receiving grooves 7 in front and rear directions. Assuming that the depth of the link receiving groove 7 is increased, the ends of the link bar 4 are rotatably received so as to be located on the same plane, respectively.
A spacer 13 is interposed between the front and rear link bars 4 to support the shaft via the spacer 13, and the position of the hinge 9 of the shaft support member 6 is adjusted to the position of the door-forming bar 1 on the rear side. The operation is performed at a position protruding toward the rear side of the door-forming bar 1 so as to absorb the thickness.

FIG. 13 to FIG.
Is extended and retracted at the same time by simultaneously arranging three or more, and in this example, three door-body-forming bars 1 over the link bar 4 so that the door-body-forming bar 1 can be simultaneously extended and contracted. In this example, the arrangement of the link device 3 is changed by changing one of the four X-shaped link bars 4 between the door body constituting bars 1 adjacent in the opening and closing direction. And a link connecting member 5 in each of the link devices 3, particularly a length extending to the shaft support member 6, and the link bars 4 are arranged between the link devices 3 adjacent to each other. By arranging the remaining link bars 4 in the same manner as described above, the series of integrated link bars 4 are used as linking link bars 4 common to the link devices 3 adjacent to each other in the opening / closing direction, and the link bars 4 intersect in the middle. Door 1 Each of the link devices 3 is simultaneously linked by the series of link bars 4 by rotatably supporting the Kubars 4 by the fixed shafts 10, respectively. 1 is simultaneously extended and contracted.

Since the configuration of the remaining link devices 3 and the like in each of the examples of FIGS. 6 to 16 is the same as that of the above-described example, the same reference numerals are given and duplicate explanations are omitted.

Each of the telescopic doors A constructed as described above is installed in the opening as a see-through vertically extending shutter, so that it can be individually expanded and contracted or simultaneously expanded and contracted. In such a case, the link device 4 is arranged so as to be located on the same surface, so that the link device 3 is made as thin as possible, and the extension and contraction of the extension door A is performed. By increasing the thickness, it is possible to prevent the thickness of the link device 3 from being increased and a plurality of the link devices 3 in the longitudinal direction of the door body constituting bar 1 and the same row or the staggered row in the opening / closing direction as appropriate. In addition to presenting a unique design due to the unconventional arrangement of the link device 3, the link connecting member 5
Becomes the accent of the telescopic door body A, and it is possible to form the telescopic door body A with further enhanced uniqueness. Can be a shutter.

By the way, the one which is made to be able to simultaneously expand and contract simultaneously is as follows.
The expansion and contraction can be opened and closed by the guide of the same guide rail as before. However, if the expansion and contraction is performed manually or electrically or manually, especially in the case of the vertical pull shutter, Since it is usual to operate a push-up operation several times upward by placing a hand at the middle position in the opening and closing direction of the telescopic door A, there is a possibility that the hand may be caught in the shrinking door member bar 1. However, in the case of individually expandable and contractible, for example, the expansion and contraction restricting means 17 is provided between the door body constituting bar 1 and the guide rail 14 at the longitudinal end of each door body constituting bar 1, especially at both ends. Then, it is possible to control the telescopic position of the telescopic door body A so as to hold the extended state at the opening surface and release it near the storage part. Also, sandwich the above hand Possibility can be eliminated that are not simultaneous telescopic link device 3 can be made having the characteristics of the opening member.

At this time, in addition to the guide of the opening / closing guide roller 15 by the opening / closing guide 16 on the guide rail 14 as shown in FIGS. Are rotatably connected by a link 18 which can be bent in a V-shape, and a guide roller 19 for restricting expansion and contraction is provided at a bent shaft support at the center thereof, while the guide roller for restricting expansion and contraction is provided on a guide rail 14. The regulating guide 20 for guiding the guide 19 may be linear in the opening surface, and may be branched from the opening / closing guide 16 in the vicinity of the storage portion so as to be separated from the opening / closing guide 16, thereby controlling the expansion / contraction position. .

Although not shown in the figure, in the telescopic door body A having a vertically extending shutter of this embodiment, for example, a pulley which is connected to one end of a wire or a chain at a lower end thereof and which is installed at both upper ends in the width direction is connected. By connecting the balancer to the other end of these wires or chains via sprockets or sprockets, it is possible to reduce the open / close load by the balancer canceling the open / close load regardless of whether it is manual or electric. In this case, if a chain and a sprocket are used and a coaxial rotating shaft for connecting the sprocket so that the sprocket rotates coaxially is provided, the above-described problem occurs particularly when the individual sprockets can be individually extended and contracted. It is possible to prevent twisting in the width direction of the telescopic door that may occur, that is, in the longitudinal direction of the bar constituting the door, and to smoothly open and close the door. Kill.

Although the illustrated example is as described above, a telescopic device that expands and contracts these link devices is installed separately from the link devices at the longitudinal end of the door-forming bar.
The telescopic door body expands and contracts with the expansion and contraction of the telescopic device, and is used as a decoration element for decorating the telescopic device. At this time, the telescopic device is installed at both ends in the longitudinal direction of the bar constituting the door body for simultaneous telescopic operation. A link device as a decorating element is provided with a single or a plurality of link mechanisms as a decorative element between them, and a link device as a telescopic element or a decorating element is provided via a link connecting member in addition to the X-shaped one described above. I-shaped,
