Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is installed in the interior and exterior openings of a building, and includes glass panels,
This invention relates to a door unit-aligned shutter that has a plurality of various partition groove units equipped with opaque panels, pipes, etc., and performs a novel horizontal opening/closing operation.

(Prior Art) Conventionally, in door unit parallel shutters having a plurality of partitioning grooves for glass panels, etc., adjacent door units are The door units are hinged to each other with connecting frames between them, the odd-numbered connecting frames are suspended from the upper frame, the even-numbered connecting frames protrude forward, and each door unit is folded alternately in a bellows style. It is known what happened.

These conventional door unit side-by-side shutters replaced steel slat shutters and greatly expanded their uses, but on the other hand, as mentioned above, they are premised on bellows-type folding, so the folding width dimension naturally increases, and the shutter There is a constraint that the effective opening width within the storage frame becomes small, and a constraint that makes it difficult to increase the width of the door unit.

(Object of the Invention) The present invention has been made in view of the problems of the conventional bellows-type folding shutter described above, and has the following features:
The purpose of the present invention is to provide a door unit-aligned shutter that can be opened and closed smoothly.

(Structure of the Invention) In accordance with the above object, the present invention connects one of the adjacent door units to the connecting frame with a hinge, so that each door unit can be freely opened horizontally in a cantilevered manner, and each door unit The hook is formed with a protruding engaging portion so that each door unit can be engaged and pulled laterally. In other words, the present invention has a hook that is movably suspended from above and is connected between each door unit. The end frame of one of the adjacent door units is partially or completely hinged to the connecting frame for upward suspension support, and each door unit can be lifted up by rotating the hinge connecting part. While the vertical stile at the end of each door unit and the adjacent vertical stile of the other door unit adjacent to each other across the connecting frame have hooks each having a hook-shaped cross section. The gist of the present invention is to provide a door unit juxtaposed shutter characterized in that a mating portion is formed in a protruding manner so that each door unit can be engaged and pulled laterally.

The present invention will be described below with reference to drawings showing embodiments.
In the figure, 1 is a door unit parallel shutter according to the present invention, and the door unit parallel shutter 1 has a door unit 6 in a shutter frame 2 consisting of upper and lower frames 3, 4 and left and right vertical frames 5, 5.
... are arranged in parallel, and a connecting frame 11 ... is installed between each door unit (see Fig. 1).

The connecting frame 11 is made of an extruded aluminum alloy, has an upper hanging block 24 with a door wheel 25, 25 fixed to its upper end, and has a joint piece 12 integrally projecting over substantially the entire length in the vertical direction.

The connecting frame 11 is movably suspended from the upper frame via the door roller 25, and each door unit 6...
- The right end vertical stile 64 of one of the adjacent door units (in this embodiment, the left-hand adjacent door unit) installed between the two door units is hinged (13 in the figure) and supported by the upper frame 3 in an upward suspension manner. Incidentally, a horizontal guide roller 14 is provided at the lower end of the connecting frame.

Next, the upper frame 3 is made of aluminum alloy extrusion material, and the upper rail 31.3 is
1 and a lower rail 32.32, and the upper rail 31.31 has a door roller 25 provided on the connecting frame 11.
..., and the door wheels 26 provided on the upper stile of the door unit are suspended from the lower rails 32, 32 and guided respectively (see Fig. 5).

On the other hand, the door unit storage section lO of the upper frame 3 and its vicinity are as follows:
It has a cross-sectional structure of approximately 1 room with one of the lower rails 32 and 32 removed, and the door wheel 26 provided on the upper stile of the door unit comes off from the removed portion 33, and as will be described later, each door The unit 6 is constructed so that it can be stored in a cantilevered manner substantially perpendicular to the upper frame when the shutter is laterally opened (see FIGS. 3 and 4).

In addition, the door unit 6... has upper and lower frames 61 and 62 and left and right end vertical frames 63 made of extruded aluminum alloy material, respectively.
．． 64 as a frame, and inside thereof there are glass panels 65 above and below the middle crosspiece 66. In this embodiment, a fitting part 67 is integrally provided along approximately the entire vertical length of the vertical stile 64 at the right end, and the above-mentioned connecting frame joint piece 12 is fitted into the fitting part 67 for hinge connection (13 in the figure).
) (see Figure 2). On the other hand, at an intermediate position in the longitudinal direction of the upper stile 61, one end of a link 15, which will be described later, is pivotally supported, and a door roller 26 is provided. - is suspended and supported on the upper frame 3, and is detached from the upper frame lower rail 32 in the door unit storage section 10.

Then, the right end vertical stile 64 of the door unit 6... and the other door unit 6 adjacent to this with the connecting frame 11 in between.
The hooks each having a hook-shaped cross section are integrally formed with engaging portions 68a and 68b protruding from the adjacent vertical stile (the left end vertical stile in this embodiment) 63, and when the shutter is closed, each door unit is closed. It can be engaged and pulled laterally (Fig. 2, Fig. 6 to Fig. 8).
(see figure). Here, the engaging portion of the hook is formed by cutting out the upper and lower ends to be several cm shorter than the entire length of the vertical stile (
(See Figures 6 and 7). Although not shown, these are stored in the upper and lower frames 3 and 4, and the engaging portions 68a and 68b, which are formed in a protruding manner, do not fit their upper and lower ends into the upper and lower frames. . In addition, 69 in Fig. 2 is the right end vertical stile 64.
This is a buffer airtight material provided between the vertical stile 63 and the adjacent vertical stile 63.

Next, the lower frame 4, left and right vertical frames 5, 5, and others will be explained.
The lower frame 4 is made of extruded aluminum alloy and is embedded and fixed in the floor of the building with an upward U-shaped groove 41, into which the lower part of the lower stile 62 of the door unit 6 and the guide roller 14 are fitted. It's forcing me. However, in the door unit storage section 10 and its vicinity, one side wall of the groove section 41 is cut out, and a separate door bag plate plate 42 is horizontally extended in its place. In the figure, reference numeral 43 denotes a reinforcing plate formed by bending a steel plate, and short pieces are fixed with screws at appropriate intervals. Also,
In the figure, 70° 70 is a buffer airtight material provided on the lower stile 62 of the door unit.

On the other hand, the left and right vertical frames 5, 5 are made of extruded aluminum alloy, and both form opposing U-shaped grooves 51, 51.
The bottom of the groove is equipped with buffer (or buffer heat 'IE) materials 52, 52 (see Figure 2 yrA), and the left vertical frame is a suspension frame for the shutter and is equipped with buffer springs 53, 53. The doorstop fins 54 and 54 are attached with screws, and the hanging frame 7 is fitted. The hanging stile 7 is connected to the right end ring unit through the link 15 and the hook when closed, through the engaging portions 68a and 68b, and the upper hanging block 24' having one wheel 25' is connected to the upper end of the hanging block 24'. and the upper frame 3 through the door roller.
(See also the upper left part of Figure 1 and the dashed-dotted line area of Figure 4). On the other hand, the right vertical frame is a door stop frame, against which the door stop frame 8 is brought into contact. The door stop stile 8 is hingedly connected to the right end ring unit and suspended above the upper frame 3 via a door wheel.

By the way, to explain the sideways opening/closing state of the shutter l installed side by side with the door unit (see each figure 2.3゜8, in addition, figure 8 is turned 90' to the left with respect to figure 2.3). (The arrow in Figure 1 indicates the horizontal pulling direction of the shutter), and as the shutter is pulled horizontally, each door unit 6... rotates the hinge connection part 13 by the link function of the link 15, and the door unit 6... Unlike the above, it is opened horizontally in a cantilevered manner and is stored in the door unit storage section IO in an overlapping manner. On the other hand, when closing the shutter, each door unit sequentially rotates the hinge connection part 13 in the reverse direction by the link function of the link 15 to move in the horizontal pulling direction, and the adjacent door units do not engage with each other or engage with each other. They are engaged and then pulled sideways one after another. Note that the link 15 also contributes to the upper hanging strength of the door unit.

To add more information, the hinge connection part is other than the one in which the joint part is integrally molded with the vertical stile, as shown in the illustrated example.

Separate hinge fittings may also be used. Similarly, the engaging portion of the hook may also be a separate short piece of hardware.

In addition to the door roller, a sliding member or the like may be used instead of the door roller to suspend the connection frame from the upper frame. Furthermore, it is not necessarily necessary to suspend the door unit at the middle position of the upper stile as long as the strength allows.

In addition, the present inventor has proposed a patent application filed in 1983 regarding a door unit parallel shutter that replaces the conventional one that folds like a bellows.
No. 1-108239, No. 61-244815, No. 61
-244816 etc.

Although the embodiments have been configured as described above, the present invention may be implemented in various ways without departing from the gist thereof.

It goes without saying that the present invention is not limited to the above embodiments.

(Effects of the Invention) Since the present invention is configured as described above, it has the following effects.

That is, in the door unit parallel shutter according to the present invention, a connecting frame that is movably suspended above the upper frame is installed between each door unit, and the connecting frame is provided with a vertical end of one of the adjacent door units. The stile is partially or entirely connected with a hinge and is suspended from the top, and each door unit can be freely pulled horizontally and opened in a cantilevered manner by rotating the hinge connection part.

It is possible to provide a shutter with side-by-side door units that can be stored in a stacked manner instead of the conventional one that folds in a bellows manner. Therefore,
Compared to the bellows-type type, the storage width of the door unit is significantly reduced, and the effective opening width of the shutter can be expanded accordingly, making it convenient for passing through and loading and unloading luggage, as well as providing an extremely open feeling. It is possible to provide a shutter with a parallel door unit.

Furthermore, in the door unit juxtaposed shutter according to the present invention, the end vertical stile of each door unit and the adjacent vertical stile of the other door unit adjacent to each other across the connecting frame each have a hook-shaped hook-shaped cross section. By forming a protruding part so that each door unit can be engaged and pulled laterally, it reduces the fluttering of each door unit when closing, providing a quiet shutter with side-by-side door units, and improving airtightness. In addition to contributing to the improvement, horizontal pulling opening and closing can also be made smooth.
