Description

[Detailed explanation of the invention] In recent years, energy conservation has been in the spotlight, and efforts to effectively utilize finite energy are attracting attention from all directions.

Particularly in large openings such as those in industrial buildings that have indoor heating, cooling, or refrigeration equipment and where transportation vehicles such as trucks and forklifts often come in and out, prevent heat from flowing in and out through these large openings. was very difficult.

Therefore, the present application provides a folding shift shutter that operates smoothly and at high speed, is safe, and is less expensive than conventional air curtains.

That is, a sheet body with a wide area that fits the opening is made by welding, gluing, sewing, etc. a belt-shaped original fabric, and a large number of aggregates are laid horizontally on this sheet body, and the aggregates are At the left and right tips protruding from both ends of the sheet body, there are rollers that fit into and move within the left and right guide rails that are installed vertically opposite the opening, and a large diameter receiving member that protrudes from the outer diameter of the rollers. In addition, the aggregate at the lowest end of the sheet body (bottom part)
is connected to a winding drum disposed at the top of the opening via a connecting member such as a belt, and when the lowermost aggregate is raised or lowered by the rotation of the winding drum, the sheet body is stacked or unstacked while the receiving members are stacked or unstacked. To provide a folding shutter whose opening is opened and closed by folding or extending the shutter.

An embodiment of the folding sheet shutter according to the present invention will be described in detail below with reference to the accompanying drawings.

Reference numeral 1 denotes a sheet body made by joining strip-shaped original fabrics using a suitable joining member 1' to form a flat surface with a wide area that fits an opening 2. A large number of aggregates 3 are attached to the sheet body 1 at intervals. are installed horizontally, and both ends of the aggregate 3 are extended from both ends of the sheet body 1, respectively, and a roller 4 and a large-diameter receiving member 14 protruding from the roller 4 are pivotally supported on this extended portion 3'. A foldable sheet shutter A is constructed.

6 is a guide rail installed vertically facing the left and right sides of the opening 2;
In the grooves 6', 6' of the guide rail 6.6, the sheet body 1 is
A shaft-supported roller 4 is fitted to the aggregate 3 placed horizontally on the frame so that it can be guided by a guide rail 6.6.

A case 7 is installed above the opening 2.

Inside the case 7, a shaft 8 that is shorter than the opening supported by the bearing plate 9 is provided and connected to a switch 10 inside the case 7, and the shaft 8 is rotated by the drive of the switch 10.

A winding drum 11 is attached to the shaft 8. The sheet body 1 moves the rollers 4 provided on the aggregate 3 into the grooves 6 of the guide rail 6.
', and the upper end is attached to the upper part of the opening 2 and suspended.

Further, the upper end side of the belt-shaped belt 12 to be suspended is attached to the winding drum 11, and the lower end side of the belt 12 is attached to the sheet body 1.
The crotch part of the bottom part 5 is connected to the aggregate 3 of the bottom part 5, and when the shaft 8 rotates, the aggregate 3 of the bottom part 5 is raised or lowered through the belt 12, and when the sheet body 1 is raised, the aggregate 3 of the bottom part 5 is connected to the aggregate 3 of the bottom part 5. By this, the receiving members 14 provided on each aggregate 3 are stacked one after another, and the sheet body 1 between the aggregates 3 is folded and raised to open the entrance/exit.

Further, when descending, the sheet body 1 folded by the stacking of the receiving members 14 sequentially extends while releasing the stacking of the receiving members 14 from the aggregate 3 at the lower bottom portion, thereby closing the entrance/exit.

The one shown in FIG. 5 is another embodiment in which the sheet body 1 is stretched over the front and back of the aggregate 3, suspended from the upper part of the opening 2 in the same way as described above, and further drilled into the aggregate 3. The bottom part 5 is connected to the aggregate 3 through the belt 12 suspended from the winding drum 11, and as the aggregate 3 rises, the aggregate 3 is moved to the receiving member 14.
By stacking, the front and back sheet bodies 1 are respectively folded outward and raised, and when lowered, they are stretched and stretched in the opposite manner.

As is clear from the above structure, the roller 4, which is pivotally supported by the aggregate 3 of the sheet body 1 suspended from the upper part of the opening 2, is fitted into the vertically installed guide rail 6.6, and the bottom part 5 of the sheet body 1 is The aggregate 3 is connected to the lower end of a belt 12 from a winding drum 11 provided on a shaft 8 driven by the opening/closing machine 10.
When the belt 12 is wound up by driving in the winding direction, the receiving members 14 provided on the lowest aggregate 3 are stacked one after another from the bottom side, and moreover, by this stacking, the sheet bodies 1 are folded with the aggregate 3 one after another. Pull it up and open it.

Further, as the opening/closing machine 10 rotates in the unwinding direction, the receiving member 14 provided on the aggregate 3 at the bottom releases the stacking, and descends while sequentially releasing the stacking, and the sheet body 1 is stretched. Finally, tension it and close the opening.

As described above, the guide rail 6.
The sheet body 1 is guided by rollers 4 which are pivotally supported on the aggregates 3 of the sheet body 1 fitted in the rollers 6, and when rising, it is sequentially pulled up from the bottom aggregate 3 side, and the receiving member provided on each aggregate 3 Reference numeral 14 indicates a receiving member 14 provided on the aggregates 3, which is stacked one after another and rises to open while folding the sheet body 1 between the aggregates 3, or descends from the lower side to extend and close the folding. is molded to have a larger diameter than the roller 4 which is pivoted on the aggregate 3 that fits into the guide rail 6, so even when stacked, the rollers 4 and 4 do not come into contact with each other, so when the roller 4 is transferred, it can be moved up and down without being disturbed. The sheet shutter A made up of the sheet body 1 can be made lightweight, and since the sheet body can be easily folded between the aggregates 3, it can be moved up and down smoothly.

Therefore, high-speed operation is possible for entrances and exits with frequent entry and exit, so even during heating and cooling, it is possible to prevent inflow and outflow to a minimum.
