[Prior art and problems to be solved by the invention] Conventional grill shutters have been constructed by connecting parallel pipes rotatably using link plates, etc. to form a shutter curtain, and then forming a shutter curtain on top of the shutter curtain. There are two known types: a winding type that is wound up and stored directly on the body or via a rope, etc., and a horizontal pulling type that is constructed so that it can be folded with a pipe and joint etc. and is folded to the side for storage. There is. In all of these cases, the shutter curtains are assembled in one piece beforehand and transported or installed.
The workability was extremely poor, and the large size had to be moved and installed, requiring a lot of manpower, which caused damage to the product and a decline in quality. In the winding method, using link plates with a large pitch would result in a large winding diameter, making it impractical.
Moreover, the design created by the structure of the pipes and links had to be monotonous, making it impossible to obtain a product with a sophisticated image, and furthermore, the product was weak in strength. Moreover, if the opening is curved due to the winding method, there are inconveniences such as the inability to wind up a curved shutter curtain onto a straight winding shaft, and the usable range of the shutter is limited. It was limited. Furthermore, scratches and noise caused by friction between links and pipes during winding have also been a problem. In addition, with the horizontal pull-out method, the space required for folding and storage is relatively large (approximately 20% of the opening width), which reduces the effective opening width. There were defects such as the rails being installed on the floor and obstructing the passage, and the rail grooves being clogged with dirt and rain.

Each of the lattice members 2a, 2, 2b is provided with a through hole 6 at both ends, through which a rope 8 whose one end is secured to a rope foil 7 arranged on the upper side of the upper storage chamber 10 passes through. The tip of the rope 8 is connected to the lowest lattice member 2b, and the lattice member 2b is pulled up by winding the rope foil 7, and the lattice members 2 are successively pulled up and stored from below so as to overlap each other. . Further, both sides of the horizontal lattice 1 are folded up and raised along guide rails 9 vertically installed on the left and right sides of the opening 19, and are raised into the upper storage chamber 10 between the rope foil 7 and the upper edge 19a of the opening. It can be paid. Here, the drive device 7a for the rope foil 7 may be electric or manual. 4 is a vertical lattice, and the vertical lattice 4
For example, grid members 12 having a rectangular cross section are arranged in parallel in the vertical direction at predetermined intervals, and are connected by connecting members 3,
This vertical lattice 4 is the lowest lattice member 2b of the horizontal lattice 1.

With the above configuration, the horizontal and vertical grids 1 and 4 are located above and on the sides of the opening 19, respectively.
Since it is separated into 5 parts and stored in a small overlapping state, there is no need to narrow the opening for storage, and the storage part can also be made small. Also, unlike in the past, there is no need to use connecting links, so
There is no need to worry about scratches or noise caused by the lattice material or link material rubbing against each other. Furthermore, since the length of the connecting member 3 can be set arbitrarily without impairing the strength of the lattice structure, it is possible to select and use a lattice pattern suitable for the building. In addition, since the same material can be used for the grid materials 2 and 12, standardization is easy, and moving, carrying in, and carrying out can be carried out after overlapping each other in small pieces, making it extremely easy to assemble and hang the grid on site. Ru. Furthermore, when the shutter is fully open, the lower lateral guide rail 5 is housed in the upper edge 19a of the opening, so there are no obstacles on the path, and since it is not installed on the ground, it is protected from dirt clogging and rusting, extending its life. be able to.
