Description

[Detailed description of the invention] (a) Field of the invention This invention relates to a shutter device for shielding openings such as entrances and exits of buildings or windows.

(b) Background of the invention Conventional shutter devices include a shutter unit configured by rotatably connecting a number of slats, a winding mechanism for this shutter unit,
It consists of guide rails located on both sides of an opening such as a window to guide the shutter unit.
The slats that make up the shutter unit are
Generally, they are made of long and thin steel plates, and are connected so that they can rotate by a predetermined angle at engaging parts formed at adjacent ends.Bending at this part allows the shutter unit to be rolled onto a thin winding shaft. This allows it to be rolled up into shapes. However, this rotation in the engaging portion causes friction and collision between the slats and with the guide rail, which causes noise when the shutter is opened and closed. Similar noise is also generated when the shutter unit vibrates due to wind or the like.

In order to solve these shortcomings, the special public
32432 and JP-A-56-167084 were proposed.

However, these devices have a new drawback that the connecting members between the slats and their mounting structure are complicated and expensive.

(c) Purpose of the invention The purpose of this invention is to provide a strong and inexpensive shutter device that allows the size of the single shutter member to be large, eliminates the need for connecting members between the single members.

(d) Structure of the invention This invention has vertical guide rails with guide grooves formed inside them arranged at predetermined width intervals,
Both ends of the single panel can be sequentially inserted into the guide groove of this guide rail from above, guide members are provided on both upper sides of each single panel, and a panel conveyance foil having a guide member receiving recess on the upper part of the guide rail is attached. The lateral rotation position of the receiving recess and the upper position of the guide rail are aligned and supported, a panel stock rail is arranged on the side opposite to the guide rail of the panel transport foil, and the lowermost unit is inserted into the guide rail. The shutter device is characterized in that the panels are connected by a connecting body such as a wire or rope of a winding drum arranged above.

(E) Example of the invention An example of the invention will be described below in detail based on the drawings.

The drawing shows a shutter device, in which reference numeral 1 denotes a vertical guide rail with guide grooves 2 formed therein at intervals of the shutter width, and 3 a single panel constituting the shutter unit.
Both ends 4 of the guide rail 1 can be sequentially inserted into the guide groove 2 of the guide rail 1 from above.

Guide rollers 5 are provided on both sides of each single panel 3.
A guide member such as the following is provided.

A panel conveying wheel 7 having a guide roller receiving recess 6 is pivotally supported on the upper part of the guide rail 1.

The position at which the receiving recess 6 of the panel conveying wheel 7 is rotated laterally is made to coincide with the upper position of the guide rail 1.

A panel stock rail 8 is arranged on the side opposite to the guide rail of the panel conveyance foil 7, and the lowermost single panel 3 inserted into the guide rail 1 is connected to a connected body such as the wire 10 of the winding drum 9 arranged above. It is connected by .

With the above-described structure, by rotating the winding drum 9 and lifting the lowermost unit panel 3 using the wire 10, the guide groove of the guide rail 1 is removed together with the unit panel 3 placed above it. 2. Ascend while being guided.

When the uppermost single panel 3 is raised to the position of the panel conveyance foil 7, the guide roller 5 of the single panel 3 is engaged by the receiving recess 6 of the foil 7,
By rotating the wheel 7 in the clockwise direction, it is conveyed onto the panel stock rail 8 on the opposite side.

When the panel stock rails 8 are tilted as shown in FIG. 2, they are sequentially pushed and arranged.

In order to prevent the single panel 3 from falling while the foil 7 is being transported, the guide rail 1 located on the outside is extended along the outer periphery of the foil 7 to form a panel prevention guide 1a.

By sequentially repeating the above-mentioned operations and arranging the single panels 3 at the guide rail 1 position on the panel stock rail 8, both side guide rails 1, 1 are arranged.
Open the gap.

Next, when shielding the space between the guide rails 1 and 1, the panel conveyance wheel 7 is rotated counterclockwise, and the take-up drum 9 is also reversed, and by reversing the wheel 7, the panel is placed on the panel stock rail 8. The guide roller 5 of the single panel 3 is engaged with the receiving recess 6 of the foil 7, and is guided from above the foil 7 to above the guide groove 2 of the guide rail 1, so that the end 4 of the single panel 3 is inserted into the guide groove. The lower end of a new panel 3 is placed on top of the panel 3 that has already been sent into the container 2, and the new panel 3 is sequentially moved down to cover the gap between the guide rails 1 and 1.

In addition, it is desirable that the circumferential speed of the above-mentioned panel conveyance foil 7 be rotated slightly faster than the circumferential speed of the winding drum 9 when it is opened, and rotated slightly slower when it is closed. Furthermore, one rotation of the wheel 7 may be synchronized with each unit movement of the single panel 3 by the winding drum 9.

In addition, in the illustration, the foil 7 and the drum 9 are coaxial, but in this case the wire 10 needs to be tied to both ends of the bottom panel 3, and when the drum 9 is placed below the foil 7, wire 10
does not necessarily have to be connected to both ends.

Furthermore, the panel stock rails 8 may be arranged horizontally and a slip conveyor such as a belt for conveying the panels may be provided.
