DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical shutter which is installed in an opening of a building as a shutter at a shopping entrance in a shopping street, a shutter of a house, or the like.

[0002]

2. Description of the Related Art As a vertically extending shutter of this type, the present inventors connect a plurality of horizontal rails via, for example, individually extendable elastic links to a shutter body, and extend and restrict the elastic link at a position above an opening surface. The guide rollers installed at both ends in the width direction of the shutter body are moved by the guide rails at both ends in the width direction by setting the restraining links that can be set in the state and release the restraint and enable successive reduction and folding. There has been proposed a vertical shutter in which the shutter body is moved up and down and opened and closed by being guided between an opening surface and an upper storage portion in a direction intersecting the opening surface.

[0003]

In this case, if the horizontal body is elongated by increasing the width of the shutter body to some extent, the horizontal rail may be bent down in the width direction in the middle due to its own weight. This tendency is observed when the shutter body is stored in the upper storage section when a relatively lightweight material such as extruded material is used. When the cross rail is bent, the shutter body shrinks somewhat in the in-plane direction. The positional relationship between the main body and the guide rails at both ends in the width direction changes, and the guide roller installed on the shutter body tilts inward and presses against the guide rails, and smoothly passes through the curved portion between the opening surface and the upper storage section. There is a possibility that the vertical opening and closing may be impaired, a squeak noise may be generated, and a feeling of anxiety may be given to an installation user or the like.

The present invention has been made in view of the above circumstances, and an object of the present invention is to solve the above-described middle-width-direction hanging-down bending of the upper storage portion of the shutter body so as to ensure a smooth lifting and lowering operation. It is an object of the present invention to provide a vertical shutter which can be opened and closed.

[0005]

According to the present invention, in addition to the guide of the shutter main body at the guide rails at both ends in the width direction, the present invention is also provided such that the guide rail is disposed at a middle position in the width direction from a curved portion or a curved portion above the opening surface. An intermediate guide rail is arranged in the section, and guides an intermediate guide such as a guide roller and a guide slash mounted on the shutter body to the intermediate guide rail so as to support the shutter body in the upper storage section at an intermediate position in the width direction. The present invention is characterized in that the shutter body is prevented from drooping to solve the problem, that is, the guide according to claim 1 is installed at both ends in the width direction of the shutter body by the guide rails at both ends in the width direction. The shutter body is moved up and down by opening and closing the shutter body by guiding the roller between the opening surface and the upper storage portion in the direction intersecting the opening surface through the curved portion above the opening surface. In the vertical shutter, an intermediate guide rail is partially installed between the upper storage portion or the curved portion and the upper storage portion, and the intermediate guide rail is disposed at a middle position in the width direction of the shutter body toward the rear side. The shutter according to claim 2, wherein the shutter body is intermediately supported above the opening surface by guiding the intermediate guide. The above-mentioned shutter body is made into a see-through shutter body formed by connecting a number of horizontal rails up and down, and the intermediate guide is provided on the back side of each horizontal rail or a predetermined horizontal rail. 2. An arrangement according to claim 1, wherein
And these are used as means for solving the above-mentioned problems, respectively, as the gist of the invention.
