Description

[Detailed Description of the Invention] [Industrial application] The present invention relates to a sheet shutter device configured to open and close an opening of a building such as a factory by a shutter curtain in which a flexible sheet is stretched over an aggregate. It is a thing.

[Prior Art] Generally, in order to open and close a large entrance / exit of a building such as a factory, a warehouse, and the like that frequently goes in and out, a conventional winding shutter in which a shutter body is formed of metal slats increases the weight of the entire shutter. In addition, since it is difficult to open and close quickly, the shutter curtain formed by stretching flexible sheets on multiple aggregates should be moved up and down along the guide rails standing on both sides of the opening. A sheet shutter device is known.

[Problems to be solved by the present invention] However, in this type of sheet shutter device, both ends of the aggregate are prevented in order to prevent the aggregate from being rubbed against the guide rails and worn when the shutter curtain is moved up and down. Further, a guide roller is provided, and a spacer or the like having a larger diameter than the guide roller is provided in order to prevent the adjacent guide rollers from interfering with each other.

For this reason, the structure becomes complicated and the cost becomes high, and when the shutter curtain is moved up and down to be stored above the opening, the spacers provided on the aggregates are vertically overlapped with each other, so that the shutter curtain is more likely to be accommodated. Therefore, there is a problem in that the opening cannot be widely opened and the appearance is not preferable.

The present invention has been made in view of the above circumstances in order to solve these problems, and a shutter curtain formed by stretching a flexible sheet on a plurality of aggregates is formed along a guide rail. Although it is moved up and down, it is possible to prevent the aggregate from rubbing and abrading the guide rails without installing a guide roller or the like, and moreover, when the shutter curtain is moved up and down, it is compact above the opening. It is an object of the present invention to provide a sheet shutter device having a simple structure that can be stored in.

[Means for Solving the Problems] In order to solve the above problems, the technical means taken by the present invention is to move a plurality of aggregates in parallel vertically between guide rails erected on both sides of the opening. A plurality of flexible sheets are stretched between the aggregates to form a shutter curtain, and the plurality of plural sheets are provided on both sides of the lower end of the shutter curtain whose suspension side is fixed to the upper end position of the opening. A pedestal having a receiving width and a depth capable of vertically hugging the aggregates in a stacked state is provided inside the guide rail, and the operation of moving the aggregates in and out of the pedestal that moves up and down through the lifting device. Then, the shutter curtain is configured to be opened and closed in a folded shape.

[Advantage of the Invention] Therefore, according to the present invention, when opening and closing the opening of the building, if the pedestal interlocked with the lifting device is lifted by operating the lifting device, both sides of the lower end of the shutter curtain are lifted. Since the pedestal provided rises while sequentially hugging and accommodating both ends of the aggregate in a superposed manner, a shutter curtain with a flexible sheet stretched between the aggregates is placed at the upper end position of the opening. It can be moved upward in a folding shape toward the fixed hanging side.

Then, when the pedestal is lowered, the folded shutter curtain can be drooped along the guide rail by its own weight to quickly close the opening.

The plurality of aggregates move up and down while both ends thereof are moved in and out with respect to a pedestal having a receiving width and a depth capable of holding the aggregates in a vertically overlapping manner. Since it does not rub against the rails and wear and the end portions of the aggregate are stored in a superposed state, the shutter curtain moved upward in a folding shape can be stored in a compact state above the opening.

[Embodiment] Next, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Reference numeral 1 is a guide rail standing on both sides of a building opening 2 such as a factory, and a plurality of aggregates 3, 3 ... Groove 4,
It is inserted in 4 and is vertically movable.

Reference numeral 5 denotes a flexible sheet formed in substantially the same shape as the opening 2, and mounting portions 6, 6 ... Are provided on the back surface side of the flexible sheet 5 at a predetermined interval. Shutter curtains 7 are formed by attaching and fixing the aggregates 3, 3 ...

The suspension base side of the shutter curtain 7 is fixed to a case 8 that is located at the upper end of the opening 2 and connects the left and right guide rails 1 and 1 via a mounting member 9, and is guided by its own weight to the guide grooves 4 and 4. Shutter curtain 7 hanging along
Is designed to close the opening 2. Further, in the case 8, a rotary shaft 12 rotatably driven by an opening / closing device 11 constituting the lifting device 10 is axially supported across the left and right guide rails 1, 1.

Reference numeral 13 denotes a support base for the shutter curtain 7, and a support base 14 having a receiving width and a depth capable of vertically holding both end portions of the aggregates 3, 3, ... It is fixed to both ends of the aggregate 3a at the bottom through the chain fixing plate 16 is attached to the back surface of the pedestal 14. The chain fixing plate 16 is connected to one end of a roller chain 18 suspended from a sprocket 17 fixed to the rotary shaft 12 and hanging downward.

The chain fixing plate 16 includes a support shaft 19 in the left-right direction,
Guide rollers 20, 20 are pivotally attached to 19 and support shafts 21 in the front-rear direction are provided.
Guide rollers 22, 22 are pivotally attached to 21. When the roller chain 18 moves up and down in conjunction with the opening / closing device 11, the guide rollers 20, 22 are guided by guide grooves 23, 24 formed in the guide rail 1.
Is guided to move up and down in the guide rail 1 in a stable state of the support table 13, and when it is moved up, the end portions of the aggregate 3 are stored in the receiving table 14 in a state where the ends of the aggregate 3 are vertically aligned. 25 is an overrun switch, and 26 is a cover sheet.

In the structure as described above, when opening the opening 2 which is closed by the shutter curtain 7, the opening / closing device 11 is operated to support the supporting stand by the roller chain 18.
When 13 is raised, the pedestals 14 fixed to both ends of the lowermost aggregate 3a ascend while sequentially accommodating the ends of the upper aggregates 3, 3, ... 3 ... Flexible sheet 5
The shutter curtain 7, which is stretched, can be moved upward in a folding shape toward the hanging base side above the opening 2.

At this time, since both ends of the aggregates 3, 3, ... Are embraced in the pedestal 14 in a superposed manner, the shutter curtain 7 is opened in the opening 2.
Can be stored compactly above the opening 2
Can be greatly opened.

On the other hand, to close the opening 2, the support table 13 is lowered and the shutter curtain 7 is guided by the guide rail 1 by its own weight.
1, the support base 13 is balanced and the opening 2 can be closed quickly and reliably.

Since both ends of the aggregates 3, 3 move up and down while being held in the pedestal 14, the aggregates 3, 3 do not need to be provided with guide rollers as in the conventional case, but the aggregates 3, 3 can be guided by the guide rails. Even if the opening of a factory or the like is frequently opened and closed, the opening and closing operation can be performed smoothly, and the entire structure can be simplified.

[Effects of the Invention] In summary, the present invention provides a plurality of aggregates that are vertically movable in parallel between guide rails that are erected on both sides of the opening, and a flexible sheet is provided between the aggregates. The shutter curtains are stretched to form a shutter curtain, and the plurality of aggregates can be vertically held on both sides of the lower end of the shutter curtain whose suspension side is fixed to the upper end position of the opening. A cradle having a width and a depth is provided inside the guide rail, and the shutter curtain is configured to open and close in a foldable manner when the aggregate is moved in and out of the cradle that moves up and down through a lifting device. Therefore, since the shutter curtain formed by stretching a flexible sheet on a plurality of aggregates moves up and down in a fold-like manner by raising and lowering the support table linked to the elevating device, it is a frequent opening / closing opening. Can also be opened and closed quickly It Since the plurality of aggregates move up and down while holding both ends in the pedestal from below, it is possible to reliably prevent the aggregates from rubbing and abrading the guide rails without providing a guide roller or the like. be able to. Moreover, since the end of the aggregate is stored in the pedestal in a superposed manner, the shutter curtain moved upward in the folding shape can be stored above the opening in a compact state, and the opening is largely opened. be able to.
