Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a curved shutter installed in a curved opening.

[Conventional technology]

All conventional shutters are flat, and flat shutters have to be installed even for openings in buildings with curved surfaces, which prevents the architectural design of curved surfaces from being fully utilized. Architects have requested the development of an adaptable curved shutter.

[Problem that the invention seeks to solve]

However, in the case of curved shutters, when the direction of movement changes from the closed position to the open position, when the direction of movement of the shutter curtain changes as the winding wire winds up, the shutter curtain formed on the two-dimensional curved surface Because of the transition to a three-dimensional curved surface, the shutter curtain did not move up and down smoothly, causing problems such as deformation of the slats and generation of squeaks when going up and down, which hindered the practical application of curved shutters.

The object of the present invention is to overcome the difficulties that have hindered the practical use of the above-mentioned curved surface shutters, to meet the needs of those involved in construction, and to provide a completely new curved surface shutter.

[Means for solving problems]

In order to achieve the above object, the curved surface shutter adopted by the present invention has slats curved with a predetermined curvature in the left and right directions and successively connected in the vertical direction so as to be mutually bendable to form a shutter curtain. The curtain is erected on both sides of the opening and can be raised and lowered from the upper part of the opening to a guide rail having a curved part along the inner surface of the ceiling. A plurality of guide rollers formed with a curvature equal to the curvature of This is characterized in that the upper drum is mounted on a shaft at the end of the guide rail.

[Effect]

When opening and closing the shutter curtain, the shutter curtain is made of curved slats because the back surface of the shutter curtain is guided by a guide roller whose outer periphery has a curvature equal to that of the slats. while being guided up and down smoothly.

〔Example〕

The present invention will be explained in detail based on an embodiment shown in the drawings.

FIG. 1 is a schematic plan view of a curved shutter of the present invention applied to a dome-shaped building, and FIG. 2 is a schematic side view of the same shutter, where 1 is a dome-shaped building and 2 is a curved opening thereof. . A pair of left and right guide rails 3 are erected on both sides of the opening 2, and the guide rails 3 are linear in the opening 2 and curved from the top of the opening 2 approximately along the curved inner surface of the ceiling. It extends inward of the building with a length approximately equal to the height of the opening 2.

Reference numeral 4 designates a shutter curtain, which consists of slats 5 curved in the left-right direction with the same curvature as the curved surface of the opening 2, and successively connected in the vertical direction so as to be bendable to each other, and both left and right ends are supported by guide rails 3. ing. When the shutter curtain 4 is lowered into the curved opening 2, it is supported on both sides by linear guide rails 3 on both sides of the opening 2, forming a two-dimensional curved surface. Here, when the hoisting wire 13 is wound up and the shutter curtain 4 is raised to the curved guide rail 3 on the ceiling, the shutter curtain 4 becomes a three-dimensional curved surface as the vertical curvature is added to the lateral curvature. to move to. In order to cope with this change, the connection between the slats 5 is not based on the interlock type in which the upper and lower ends of the slats are wrapped around each other, but rather on the third
As shown in Fig. 4, the upper and lower ends of the slats are overlapped, and this overlapping part 5' is loosely crimped at multiple locations with U-shaped studs 6, and then from both left and right ends of the slat 5 to the center. One of the slat rivet holes is made into a long hole 7 which is gradually elongated from both left and right ends of the slat 5 toward the center so that the width of movement in the vertical direction between the slats can be gradually increased. In addition, FIG. 3 shows an example in which the overlapping part 5' of the slats 5 is double crimped, and FIG. 4 shows an example in which it is single crimped. Compared to double crimping, single crimping has a greater degree of freedom in connecting the slats 5 to each other. Suitable for fitting the shutter curtain 4 when the curvature of the three-dimensional curved surface is large. Furthermore, if the curved surface of the opening 2 is extremely gentle and the curvature of the slat 5 in the left-right direction is extremely small, it is not necessary to make the riveting holes into elongated holes.

Reference numeral 8 designates a guide roller whose outer periphery is formed to have a curvature equal to that of the slat, and which slides into contact with the back surface of the shutter curtain 4. A plurality of guide rollers 8 are mounted on the curved portion of the guide rail 3 at appropriate intervals, and are formed in a spindle shape having a rotating surface whose generatrix has the same curvature as the left-right curvature of the slat 5. . Note that the guide roller 8 does not have a spindle-shaped full rotating surface as shown in FIG. 1, but instead has a spindle-shaped virtual rotating surface indicated by a chain double-dashed line in the figure by a plurality of rotating plates 8a as shown in FIG. It may also be configured to form. In this guide roller 8', by freely rotating the rotary plate 8a with respect to the shaft 8b, the difference in linear velocity of the spindle surface from the center to both ends of the spindle-shaped guide roller can be made constant. There is no friction between the shutter curtain 4 and the curved surface of the shutter curtain 4, and the shutter curtain 4 can be moved smoothly without being damaged.

A hoisting shaft 9 is mounted on the ceiling end of the guide rail 3, and a plurality of hoisting drums 10 are mounted on the shaft 9.
A balance spring 11 is installed to balance the weight of the shutter curtain 4, and the shaft 9 end is connected to a shutter opening/closing device 12. Its upper end is then suspended. The hoisting wire 13 is coated with vinyl to prevent mutual damage due to friction with the guide roller 8 during hoisting and lowering.

In the configuration described above, when the shutter is lowered, the curved shutter curtain 4 is supported on both sides by the linear guide rails 3 on both sides of the opening 2 to form a two-dimensional curved surface, and is adapted to the curved opening. and close this. Next, when the shutter opening/closing device 1 is opened, the hoisting shaft 9 rotates, and the hoisting drum 10
As a result, the hoisting wire 13 is hoisted up, and the shutter curtain 4 begins to rise. When the shutter curtain 4 is placed on the curved guide rail 3 above the opening 2, the shutter curtain 4 curves not only in the left-right direction but also in the vertical direction and transforms into a three-dimensional curved surface. To cope with this three-dimensional curvature, it is necessary for the slats 5 to gradually increase the gap between the slats 5 from both left and right sides to the center.
The letter rivets 6 freely move and correspond to each other, and the shutter curtain 4 can easily form a three-dimensional curved surface without deforming the slats 5 or generating squeaks. The shutter curtain 4 has a guide roller 8 whose outer periphery has a curvature equal to that of the slat.
Then, it is pulled up by the hoisting wire 13 to the end of the guide rail 3 while being supported by the back side thereof, and then stopped, and the opening 2 is opened.

To close the opening 2, a shutter opening/closing machine 12 is used.
Shutter curtain 4 is closed by closing the shutter curtain 4.
operates in the opposite manner to the above, and the opening 2 is closed.

〔Effect of the invention〕

The present invention forms a shutter curtain by sequentially connecting slats curved with a predetermined curvature in the left and right directions vertically so as to be bendable to each other, and the shutter curtain is erected on both sides of an opening, and A guide rail having a curved portion extends from the upper part of the opening along the inner surface of the ceiling so that the guide rail can be raised and lowered, and the curved portion of the guide rail has an outer periphery formed to have a curvature equal to that of the slat, so that the shutter curtain can be moved up and down. A plurality of guide rollers that slide in contact with the back surface are mounted on shafts at appropriate intervals, and a hoisting drum to which a hoisting wire that suspends and supports the upper part of the shutter curtain is fixed is mounted on the end of the guide rail. Because it is,
A shutter curtain that opens and closes a curved opening is guided up and down by a guide rail that curves from the top of the opening along the inner surface of the ceiling, and is smoothly guided up and down by guide rollers. The invention makes it possible to install a curved shutter even in the case of a closed shutter whose direction of movement changes from a closed position to an open position in a curved opening of a building with a curved structure, and it is now possible to install a curved shutter in a curved opening of a building. In response to requests, the degree of freedom in architectural design can be greatly expanded.
