Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a roll-up shutter that is attached to the opening of a garage or building.

[Conventional technology]

Conventional hoisting type shutters have a storage chamber for the slats installed on the outside of the upper part of the window frame or on the outside of the wall above the opening of the building, and a drum is pivotally supported in the storage chamber, and one end of the slat is attached to the drum. is fixed, and the other end of the slat, which can be wound, is inserted into the guide rail provided on the outdoor side of the building opening through the entrance opening under the storage chamber, and the drum is rotated by a drive device.
The slats were raised and lowered by the rotation of the drum. However, if the slat storage chamber is attached to the outdoor side of the wall, the storage chamber will protrude beyond the wall to the outside, resulting in a very unsightly appearance and making it difficult to rotate the drum from the indoor side. If the storage chamber is installed on the indoor side of the wall, the slat must be guided from the storage chamber installed on the indoor side through the wall to the outdoor side of the opening.
The problem was that it was troublesome to install and that it was difficult to smoothly insert and remove the slat.

[Purpose of invention]

The winding type shutter of this invention allows smooth insertion and removal of the slats, reduces the protrusion from the wall of the slat storage chamber to the outside, makes the shutter easy to install, and allows the drum to be rotated from the indoor side. The goal is to make it possible to move.

[Structure of the idea]

In order to achieve the above-mentioned purpose, the devised roll-up shutter has two parts: a buried part where the slat storage chamber is attached to the upper wall cavity of the opening of the building, and an external peripheral wall part which is a vacant part wider to the left and right than the buried part. Consists of a top bag section,
The length of the top bag part is made larger than the length of the buried part, a slat entrance and exit is provided under the top bag part, a slat winding drum is rotatably supported in the storage chamber, and a drum driving device is installed on the outside of the side of the buried part. The drive device can be operated indoors.

〔Example〕

Next, the structure of the proposed winding type shutter will be explained with reference to the drawings of the embodiments. Reference numeral 1 denotes a slat storage chamber that rotatably supports the drum 4, and the storage chamber 1 is located above the lintel m of the opening M of the building. It consists of a buried part 2 that is inserted and fixed into a hollow part A provided in a wall W, and a top bag part 3 with a waterproof structure that is attached externally to the outer peripheral wall W of the empty part A, which is wider to the left and right than the buried part 2. The part length L is larger than the buried part length l, a slat entrance 13 is opened on the indoor side of the bottom wall 3a of the top bag part, and the top bag part 3 except the entrance 13 is covered with an outer plate 23. Specifically, The buried part 2 is inserted into the empty part A of the wall W, and the left and right sides 2a of the buried part 2 are nailed or screwed to the pillars P forming the empty part A. The left and right sides of the bag portion 3 are attached externally to the pillar P. A drum 4 is rotatably supported in the center of the storage chamber 1, and the drum 4 is rotated from inside the room by a suitable drive device 6. Reference numeral 5 denotes a continuous slat that can be wound up, and the slat 5 has one end fixed to the drum 4 and the other end fitted to a guide rail R provided on the outdoor side of the building opening M from the entrance 13 of the storage room top bag part 3. It is inserted and wound or unwound as the drum 4 rotates, moves up and down along the guide rail R, and opens and closes the building opening M. The drive device 6 for the drum 4 includes a worm wheel 14 fixed to the drum shaft 4a, a rod 7 supported on the outside of the side surface 2a of the buried part and reaching the indoor side of the building, and a rod 7 fixed at the end of the rod 7 and meshing with the worm wheel 14. It consists of a worm screw 18, a ball chain 9 and a motor (not shown) that are attached to the rear of the rod 7 exposed on the indoor side, and the rod 7 is passed through the column P of the hollow part A, and one end of the rod is attached to the top bag part. 3, or a universal joint 8 can be interposed in the middle of the rod 7.

Since the proposed roll-up type shutter has the above-mentioned structure, when installing it in the opening M of a building, the buried length l of the slat storage chamber 1 is placed in advance on the upper wall W of the lintel m forming the building opening M. A slightly larger cavity A is formed, and the buried part 2 of the storage chamber 1 is inserted into this cavity A from the outdoor side, and the buried part 2 is attached to the cavity A, and the part 2 is laterally wider than the buried part 2. After circumscribing the top bag part 3 to the outdoor side of the wall W and attaching the outer periphery of the top bag part 3 to the wall W by nailing or screwing, the top bag part 3 is attached to the outdoor side of the window frame F or building opening M. Then, a guide rail R continuous to the entrance/exit 13 of the top bag section 3 is attached, and the other end of the slat 5, one end of which is fixed to the drum 4, is inserted and inserted through the entrance/exit 13 of the top bag section 3 along the guide rail R. A driving device 6 for the drum 4 is attached to the outside of the side surface 2a of the buried portion, so that the slat 5 can be raised and lowered from inside the room.

Note that the specific implementation is not limited to the above embodiment, and for example, before installing the storage chamber 1 in the wall cavity A, a drive device for the drum 4 is installed in advance on the outside of the side surface 2a of the buried part. 6 can be attached, or even if the guide rail R of the slat 5 is integrated with the outdoor side of the window frame F, the same purpose can be achieved. The shape and structure of the top bag portion 3 and the slat 5 can be changed as appropriate as long as they do not go against the gist of this invention.

[Effect of idea]

Therefore, the hoisting type shutter of the present invention consists of an embedded part in which the slat storage chamber is embedded in the hollow part of the wall, and a top bag part which is attached to the outdoor side of the wall, so that the slat storage chamber does not protrude outside from the wall. The number of slat storage chambers is reduced by the thickness of the wall, the exposure of the slat storage chambers is halved compared to the conventional case, and the appearance of mounting the slat storage chambers on buildings is significantly improved. Moreover, the storage chamber is constructed by inserting and fixing the buried part into the wall cavity, and externally attaching the outer periphery of the top bag, which is larger on both sides than the buried part, to the wall. Not only is it even more powerful, but since the drum drive device is supported on the outside of the side of the buried part, it is easier to install the drive device, and the drive device can be guided indoors for operation. . In addition, by making the slat storage chamber semi-external as described above and reducing the amount exposed to the outside of the room from the wall, the curvature of the slats moving in and out of the storage chamber along the guide rail becomes smaller. This invention has beneficial effects as a shutter for building openings and garages, as the slats can be moved up and down easily and the drum can rotate easily.
