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 no choice but to be installed at openings in curved buildings, but the design cannot be fully utilized, so a curved shutter that can be adapted to curved openings is required. The development of shutters was requested by those involved in architecture.

[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 it is rolled up, the shutter curtain formed as a two-dimensional curved surface transitions to a three-dimensional curved surface. As a result, the slats could not cope with this and were deformed, causing cracking noises, 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 shutters, to meet the needs of those involved in construction, and to provide a completely new curved shutter.

[Means for solving problems]

In order to achieve the above object, 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 mutually bendable, and the shutter curtain is formed by connecting the slats with the white rabbit of the slats. The slats are supported through guide rollers having equal rotating surfaces, and are wound up and down by a plurality of hoisting wires that suspend the upper part of the shutter curtain, and the slats are gradually moved from both left and right ends toward the center of the slats. A curved shutter is constructed by increasing the vertical movement width of the slats and connecting them.

[Effect]

Therefore, the shutter of the present invention allows a curved shutter to be installed in an opening with a curved surface configuration, and when the shutter is opened or closed, the curved shutter curtain is guided by a guide roller having a rotating surface equal to this curvature, which is different from the conventional shutter. Similarly, the slats are smoothly rolled up and lowered, and the slats are connected by gradually increasing the width of vertical movement from the left and right ends toward the center. Even in the case of a changing fit, the slats bend without deforming or making a sound, and the shutter curtain opens and closes smoothly.

〔Example〕

The present invention will be explained in detail below based on the illustrated embodiments.

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 idle rails 3 are installed on both sides 1111 of the opening 2.
is erected, and this guide rail 3 has a height of 1 at the opening 2.
It has an M-line shape, is curved from the upper part of the opening 2 approximately along the curved inner surface of the ceiling, and extends inward of the building for a length approximately equal to the height of the opening 2.

Reference numeral 4 denotes a shutter curtain, which is made up of slats 5 curved in the left and right directions with the same curvature as the curved surface of the opening 2 and sequentially connected in the vertical direction so as to be bendable to each other, and supported by guide rails 3 at both left and right ends. . 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.

When the shutter curtain 4 is rolled up and raised to the curved guide rail 3 of the ceiling, the shutter curtain 4 becomes a three-dimensional curved surface with vertical curvature added to the lateral curvature. In order to accommodate this change, the connection between the slats 5 is not based on the interlocking method in which the upper and lower ends of the slats are wrapped around each other, but rather by overlapping the upper and lower ends of the slats 5 as shown in FIGS. 3 and 4. Polymerization part 5' is U
The rivet style is used to loosely rivet the slats with the rivets 6, and the rivet holes of the slats of -10,000 are attached to the slats so that the width of vertical movement between the slats can be gradually increased from both left and right ends of the slats 5 toward the center. The long hole 7 is made gradually longer from both left and right ends of the hole 5 toward the center. In addition, FIG. 3 shows an example in which the overlapping part 5' of the slat 5 is double crimped, and FIG. 4 shows an example in which it is single crimped. In contrast 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.

The hanging wall at the top of the opening 2 is long and the shutter curtain 4 can be placed vertically on a straight guide rail,
Or, if the curved surface of the opening 2 is extremely loose and the curvature of the slat 5 in the left and right direction is extremely small,
There is no need to make the rivet holes for the riveting process into elongated holes.

Reference numeral 8 denotes a guide roller, which is surrounded by a plurality of guide rollers perpendicularly to both guide rails 3 at appropriate intervals on the curved part of the guide rail 3 overflowing to the ceiling, and has a rotating surface whose generating line has the same curvature as the left-right curvature of the slat 5. It is formed into a spindle shape. 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 entirely formed by a plurality of rotating plates 8a as shown in FIG. It may be something like this. By allowing the guide roller 8' to rotate freely with respect to the rotary plate aae axis 8b, the spindle shape can be made to have a constant linear velocity difference on the spindle surface from the center to both ends of the roller. Therefore, 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 installed horizontally at the end of the guide rail 3 on the ceiling side, and a plurality of hoisting rams 10 and a balance spring 11 for balancing the weight of the shutter curtain 4 are mounted on the shaft 9.
is mounted, the end of the shaft 9 is connected to a shutter opening/closing device 12, and the shutter curtain 4 is suspended at its upper end by a plurality of hoisting wires 13, one end of which is fixed to each hoisting drum 10. The winding wire 13 is coated with vinyl to prevent mutual damage due to friction with the guide roller 8 when winding up and lowering.

In the slanted configuration, when the shutter descends, the curved shutter curtain 4 forms a two-dimensional curved surface with the straight lines on both sides of the opening 2 being supported by the rails 3 on both sides, and the opening having the same curved surface as the shutter curtain 4. Close this in accordance with . Next, when the shutter opening/closing device 1 is opened, the hoisting shaft 9 rotates, the hoisting wire 13 is hoisted by the hoisting P ram 10, 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 and right directions but also in the up and down direction and transforms into a three-dimensional curved surface. In order to accommodate this three-dimensional curved surface, it is necessary for the slats 5 to gradually increase the gap between the slats 5 from both left and right ends to the center. 6 freely move and correspond to each other, and the shutter curtain 4 forms a three-dimensional curved surface easily without deforming the slats 5 or generating a clenching sound. The shutter curtain 4, which has a rotating surface with the same curvature as this, is sequentially supported by the idle rollers 8 and is rolled up to the guide rail 30P14 and then stopped to open the opening 2.

To close the opening 2, the shutter curtain 4 is operated in the opposite manner to the above by closing the shutter switch 12, and the opening 2 is closed.

〔Effect of the invention〕

As described in detail above, according to the present invention, a shutter curtain is formed by sequentially connecting slats curved with a predetermined curvature in the left and right directions in a vertical direction so as to be bendable to each other, and the shutter curtain is The slats are wound up and down by a plurality of hoisting wires that are supported through idle rollers and suspend the upper part of the shutter curtain, and the slats are connected from both left and right ends of the slats to the center of the slats. Since the vertical movement width of the slats is gradually increased and connected to form a curved shutter, the direction of movement changes from the closed position to the open position at the curved opening of a building with a curved surface structure. It is now possible to install curved shutters even in the case of shutters that fit within a certain size, meeting the requests of those involved in architecture, and has the effect of significantly expanding the degree of freedom in architectural design compared to the past.

In addition, since the curved shutter has an arched shape when closed, it has a feature that its wind pressure resistance is stronger than that of a flat shutter.
