Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a winding device for a sheet shutter comprising a plurality of strip-like sheets suspended in parallel.

[Prior art and its problems]

Conventionally, it has been known to shield an entrance/exit by hanging a plurality of strip-shaped sheets in parallel from the upper end of the entrance with their left and right edges overlapping each other, but it is not always possible to Because of this, there was a problem in that the seats got tangled and got in the way when going in and out with luggage, hindering transportation work.

[Purpose of this invention]

The present invention was devised in view of the drawbacks of the conventional examples, and its purpose is to provide a sheet shutter that does not get tangled when carrying luggage in and out of the vehicle, and does not obstruct transportation work. There is to provide the above equipment.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention has the following features in the first item: a plurality of longitudinally flexible inner sheets 1 and outer sheets, which correspond to the opening height of the entrance and exit, and are provided at regular intervals and in a staggered manner on the inside and outside. In a sheet shutter A formed by sequentially overlapping the side edges of sheets 1', two parallel inner winding drums 2 and two outer winding drums 2' are arranged in the width direction of the opening. The structure is such that it can be wound up into individual parts.

In Section 2, the inner sheet 1 is transferred to the winding drum 2 via guide shafts 3, 3' provided close to the bottom of the winding drums 2, 2'. The side sheet 1' is configured to be wound up on a winding drum 2'.

This technical method is adopted.

[Operation] When the winding drums 2, 2' are rotated and rewound,
The belt-shaped sheets 1, 1' wound around these drums 2, 2' hang down while their left and right edges overlap one another to cover the entrance and exit.

Conversely, when the winding drums 2 and 2' are rotated in the winding direction, the inner and outer strip sheets 1 and 1' are separated to the winding drums 2 and 2' immediately before winding, and the respective winding drums 2 , 2'.

〔Example〕

To explain the embodiment of the present invention with reference to the drawings, in Fig. 1, 1 and 1' correspond to the opening height of the entrance and exit, and a plurality of vertically long sheets are provided on both the inside and outside at regular intervals in a staggered manner. As shown in Fig. 2, the width direction of the flexible belt-shaped sheet is slightly curved alternately in opposite directions, and the left and right side edges are successively overlapped to form the sheet shutter A, and the side walls are Part B
The opening is covered by the opening of the entrance and exit, which is formed by the ceiling C and the ceiling C, and is arranged so as to be openable and closable in the vertical direction.
In Figure 4, 2 and 2' are C inside the ceiling of the entrance/exit.
The above-mentioned belt-shaped sheets 1 and 1' are wound onto the winding drums 2 and 2', respectively, using the winding drums of a sheet shutter A that is installed parallel to the opening width direction of the entrance and exit at a constant interval. be. Each strip-shaped sheet 1 wound around one winding drum 2 is placed opposite to a portion at a constant interval between the facing strip-shaped sheets 1' wound around the other winding drum 2', and these sheets 1,
The structure is such that when the sheet 1' is hung down, the left and right edges of the belt-like sheets 1, 1' on both sides can overlap with each other as described above.

Further, the winding drums 2 and 2' have bearings 4 and 4 at both ends thereof.
4, it is rotatably supported in the ceiling C, and can be rotated by operating a rotary drive mechanism such as a motor or a string-like object.

In Fig. 4, 3 and 3' are the winding drum 2,
The guide shaft is arranged in parallel with the winding drums 2, 2' in the same direction as the winding drums 2, 2', and is arranged opposite to each other with a small gap that presses the belt-shaped sheets 1, 1'. 5,5 both side walls B of the entrance and exit,
It is rotatably supported above B.

The lower ends of the belt-like sheets 1 and 1' constituting the sheet shutter A are provided with an L-shaped cross section so that the lower ends do not pass above the guide shafts 3 and 3' when winding up the sheet shutter A. Or inverted T
It is desirable to provide a shaped stopper piece or the like.

[Effect]

When the sheet shutter A, whose lower end is wound up to near the bottom of the guide shafts 3, 3', is unwound by rotating the winding drums 2, 2', the sheet is wound on these drums 2, 2'. The loaded strip sheets 1, 1' are suspended by guide shafts 3, 3' while sequentially overlapping their left and right edges to cover the entrance and exit, and the winding drums 2, 2' are rotated in the winding direction. When the belt-like sheets 1, 1' rise from the guide shafts 3, 3', they separate toward the winding drums 2, 2' and are neatly wound on the respective winding drums 2, 2'.

[Other Examples]

FIG. 6 shows another embodiment of the present invention. In the embodiment described above, the strip sheets 1 and 1' were fed out from between the winding drums 2 and 2', but in this embodiment, only one winding was fed out. Since the left and right ends of the strip sheets 1 from the other winding drum 2 are overlapped on the take-up drum 2', the strip sheets 1, 1' are suspended from one winding drum 2', and the effect is the same as that of the embodiment described above. It is similar to Although shown in the figure, a guide shaft is not necessarily required in this case.

〔effect〕

As mentioned above, the present invention provides a sheet shutter A that is formed by sequentially overlapping the side edges of a plurality of vertically elongated flexible inner sheets 1 and outer sheets 1'.
, two parallel lines arranged in the width direction of the opening
Since this relates to a winding device for a sheet shutter characterized in that the book is wound up by an internal winding drum 2 and an external winding drum 2', the winding drum 2 . or,
If you frequently pass through the entrance with luggage, etc., or if a large truck enters, drive the winding drums 2, 2' to rotate and wind up the strip sheets 1, 1', and open the entrance to the front. It can facilitate entry and exit.

Furthermore, even though the strip sheets 1 and 1' overlap each other on both sides, they are separated and wound onto two parallel winding drums 2 and 2', so that they can be wound accurately and smoothly. You can wind up and rewind.

Note that a guide shaft 3, which holds the belt-shaped sheets 1, 1' in close proximity to the lower part of the winding drums 2, 2',
3' may be provided; in this case, the belt-like sheets 1,
Winding and unwinding can be performed while maintaining the overlapping state of 1' more accurately.
