Description

Slotter screen {Slotter screen}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to slotter screens used in shutters or sunshade screens installed in building openings.

Conventionally, this type of shutter has a slotter screen connected by a plurality of forced slotters, but since it cannot be deployed horizontally, in the case of sunshade screen, a separate screen is wound on the winding drum installed at the top. I use it. The conventional shutter is provided with a cylindrical hinge having an "S" cross-sectional shape having an opening on the slotter at both periphery of the slotter constituting the shutter. Adjacent slotters thereof can be mutually embraced by the cylindrical hinges, that is, one hinge guides the cylindrical outer periphery of the hinges opposed to the slotted openings (slits) as described above, and is concentrically fitted to the engaging portions and rotated in both directions on both sides. Because of this, the slots connected in this way are configured like chain links, and when the slotter screen is released from the winding drum, the above-mentioned concentric fittings of each slotter collapse, resulting in a play in the vertical direction and the out-of-plane direction. Due to the clearance gap, each slotter has a metal noise due to collision between inner and outer peripheral surfaces of the cylindrical hinges.In addition, when external pressure such as wind pressure is loaded on the unfolded slotter screen, noise is generated due to the above clearance gap between each slot. The clearance jaws are released and integrated with adjacent slotters The resistance to pressure increases the amount of warpage of the entire screen, so each slotter needs a certain amount of flexural strength. For this reason, there may be a case of reinforcing the bent on the slotter surface outside the cylindrical hinge, but there are countless uneven lines on the slotter screen surface, thereby accelerating the fouling by debris such as debris. In addition, the uneven line is in contact with the noodle (funnel spout) formed in a fan shape at the top of the longitudinal guide roller during the opening and closing operation of the slotter screen is wound and unwinded in the winding drum, causing a metal noise. In addition, in the conventional sunshade screen, one side of the plurality of bending arms is fixed to the upper wall of the opening, and the other side is fixedly connected between the horizontal supports, respectively, and the wall between the flat frame composed of the elastic and the horizontal frame. It is to install a foam roll screen which is extended out of the axially supported winding drum, but the foam screen is not durable and has a drawback of being easily aged. In addition, when the elastic piece which decays in the direction of extension of the curved section is deteriorated, the expanded screen cannot be tensioned, and the central part of the screen is bent, so that there is a closed end where the rainwater accumulates, and there is also a problem that is not good in appearance. Due to the large weight as well as the cost increase by many constituent members, such as a plurality of bends, support bars, and roller screens having a winding structure, there is an overload of construction costs even when mounted on a wall of a height. In addition, because the sunshade screen is fixedly installed on the top wall of the opening, the screen must be pulled out relatively deep when shading up to the bottom of the opening according to the sun's breaking strength. Thus, the deeper the elongation width, the greater moment acts on the wall surface side of the bending support arm, and the rigidity of the mounting wall surface is also required. In addition, when opening the shutter with the electric shutter, the interior illumination is reduced to darken, and in the case of the sun at low altitude, the shutter should be almost closed in order to completely shade the sun. It is.

In order to solve the above problems, noise is prevented, and the shutter and the shade screen can be used as both of the present invention. The present invention is a slotter screen in which a plurality of slotters are connected at their ends. Within the thickness of the slotter between the protruding surface and the inner periphery recessed surface, slotter-shaped openings are formed on both ends of the slotter in the opposite curved direction, and at the same time, the extension portion of one "S" -shaped outer peripheral surface is formed. The extension portion of the other "S" shaped outer circumferential surface is connected to a plane jaw perpendicular to the tangent of the outer circumferential surface, and the hinge portion connected to the flat jaw parallel to the flat jaw constitutes a hinge between adjacent slotters. The slots and protrusions enclosed in a combination are inserted, and each slotter is surrounded on the outer circumferential surface when it is unfolded in a straight line in a wound state. Surface projections and curved recesses are hooked to be the support points, and the upper surface of the slotter screen is detachably coated and used as a sunshade roller screen, and the auxiliary rail (board ram) of the slotter screen or sunshade roll screen The end slotter is fixed on the screen in the vertical and horizontal directions.

Referring to the configuration and embodiment of the present invention as described above in detail based on the drawings as follows. 1 is a side cross-sectional view of the slotter, in which the slotter 8 is formed of a curved circumferential surface as an aluminum extruded shape, each hinged at both edges within the size d of the slotter thickness between the outer circumferential surface R1 and the inner circumferential surface R2. (A) (B) is formed. The hinges A and B each have slotter-shaped openings 9 and 10, and the openings 9 and 10 thereof are opened in opposite directions with respect to the curved main surface to form an "S" -shaped curved surface S1 ( S2) is formed. Adjacent slotters 8 are attracted to each other when the projections 1a, 2a and recesses 1b, 2b surrounded by curved surfaces S1 and S2 on the "S" rule have a very small gap and are viewed in cross section. It is fitted at the locking section so that it can be held.

And the one side tangential extension of the protrusion 1a of the "S" shaped curved surface S1 of the hinge A constitutes a straight portion 3a, and the radius r1 centered on the center point 1c of the curved protrusion 1a thereof. In contact with the concave curved surface 4a, the concave curved surface 4a is in contact with the flat jaw (5a) in contact with the slotter outer peripheral surface (R1). The indentation portion 2b of the "S" -shaped curved surface S1 of the hinge A embraces the protrusion 2a of the hinge B, and the angle ( θ ) to which the slotter 8 is bent and rotated in a straight line-expanded state ( θ) ) Is deeply recessed so that the circumferential arc which is soft on the outer circumference of the protrusion 2a of the hinge B is in contact with the inner circumferential surface R2 of the slotter. The "S" curved surface S2 of the hinge B is One side tangential extension part of the recessed part 1b of Nb forms a straight part 3b, and contacts the recessed curved arc 4b of radius r2 centering on the center point 1c of the curved part of the recessed part 1b, The arc 4b is in contact with the flat jaw 5b perpendicular to the tangent of the slotter outer peripheral surface R1. The flat jaw 5a of the hinge A mentioned above is parallel to the flat jaw 5b. The " S " curved surface S2 of the hinge B and the outer periphery of the protrusion 2a are circular arcs of the radius r3 around the center point 1c of the concave inlet 1b, and are formed on the slotter inner circumferential surface R2. Connected. On the inner circumferential surface side of the curved slotter 8, reinforcing pieces 6a, 6b branched from the hinges A and B are formed, and guide grooves 7 having a flat " C " Form. The slotter 8 having the cross section is bent and rotated freely so that the protrusion 1a and the indentation 1b enclosed by the “S” self-curved surfaces S1 and S2 can be embraced by each other, so that adjacent slotters are mutually adjacent. The hinges A and B are not separated from each other even at the bending angle of the maximum angle θ . In addition, the slotter 8 is fitted with protrusions 1a and recesses 1b of the hinges A and B, which are expanded horizontally (in a straight line) in a wound state, so that the slotters 5a and 5b are mutually slotters. 8) It becomes a supporting point so that the repulsion unity can be achieved, and each slotter 8 supports the adjacent slotters to be joined together by compressive stress so that a continuous straight plane can be maintained. Hinge (A) (B) is a bending stress acts on the portion of the short support point distance of the hinge (A) (B) at this time can support a sufficient bending stress because the support point distance is short. In addition, the reaction force when each slotter 8 is horizontally supported becomes a compressive stress that is connected to the curved surface of the slotter at the flat jaw 5a and 5b, thereby maintaining balance.

In general, the allowable compressive stress of the metal and the synthetic resin has a strength that is several times the allowable bending stress, so that the load transmitted to the arcuate curved body part other than the hinge portion of the slotter is most compressive. The continuous spiral-coupled slotter screen does not bend downward significantly when it is horizontally expanded in the air in a letter shape, and has a strength that maintains a plane.

Next, in the embodiment of the product in which the slotter screen of the present invention is used, FIG. Fig. 3 is a front and rear view of a sliding type (lateral type) shutter having a structure in which a shutter case 17 in which a winding drum is inscribed on both sides of an opening is fixed, and both sides of the slotter screen 8s are accommodated. In any case, the slotter screen 85 of the present invention is used, and reference numeral 12 in FIG. 2 denotes a shutter case in which a winding drum is stored, and 13 denotes a longitudinal guide rail that wets both ends of the slotter screen 8s. , 14 and 15 are upper and lower guide rails for slidingly guiding the upper and lower ends of the slotter screen 8s, and 16 are fixed to the ends in the slotter screen 8s as lateral movements guided by the upper and lower guide rails 14 and 15. . Due to the lateral pulling operation of the transverse movement 16, the slotter screen 8s is wound and received by the bias elasticity of the winding spring stored in the winding drum (not shown).

When wind pressure is applied to the expanded slotter screen 8s as described above, the slotter 8 has a curved stress in the longitudinal direction and a compressive stress in the direction perpendicular to the longitudinal direction. In the center of the slotter screen 8s, the compressive stress is distributed and transferred in the vertically opposite direction in FIG. 2 and in the horizontally opposite direction in FIG. That is, since compressive stress is transmitted in the winding drum direction near the winding drum of the flattened slotter screen 8s, the winding drum is stretched to the screen and rotated in the extension direction like a conventional shutter, thereby amplifying the warpage of the screen. The flaw to be solved is eliminated.

4 and 5 are views of a sunshade screen that is extended with an inclined plane in the air in a state in which the slotter screen is separately supported without using a supporting arm, as a separate embodiment of the present invention. As a perspective view, the state in which the slotter screen 85 is fully developed or half developed is displayed. When the end slotter 8a of the slotter screen 8s is fixed to the storage case 18 fixedly disposed on the wall with a very small inclination angle (15 to 20 °), the motor is dropped by its own weight in the wound storage state. It is a structure in which the slope plane is installed. The expanded slotter 8 has the flat jaw 5a, 5b of the hinge joint portion compressed as described in detail in FIG. 1 and there is no bending downward. It is delivered to and supported by the second rear slotter 8a. Furthermore, each slotter 8 is formed with the slits listed holes 19 continuously to such an extent that the strength does not decrease so that the magnetic weight can be reduced.

Reference numeral 20 denotes an operation code that fixes one shaft end to the lower side of the storage case 18, and its extension part is locked to the front end slotter 8b to reciprocate the upper side of the slotter screen 8s to be fixedly embedded in the storage case 18. It loads downward via the normal roller fastening cord guide | route (illustration omitted) which was mentioned. And when the operation cord 20 is pulled down in FIG. 5, the leading slotter 8b is wound upwards, and the adjacent slotters are also wound up upward while being interlocked and wound up, and when the operation cord 20 is locked to the roller fastener, the slotter screen Is set to any extension.

In addition, reference numeral 21 denotes a polyester forge screen subjected to a water repellent coating, in which both ends thereof are bonded with a synthetic resin tape and the strap thereof is wound in the guide groove 7 of the slotter 8 in FIG. ) Is sandwiched between the slaughter screen (8s) and the two-layered forge screen (21). Since the slitting hole 19 of the slotter 8 is covered with a foam screen 21, leakage of water or invasion of solar heat is prevented and waste is not moored at the hinge joint of the slotter. In addition, since the sun visor roller screen is a very sophisticated structure consisting of a slotter screen, a polyester cloth screen, and an operation code, the sun visor roller screen is larger in width than the conventional sun awning roller screen, which is cost effective and easy to operate.

FIG. 6 and FIG. 7 allow the slaughter screen fixedly disposed on the wall as shown in FIG. 4 to be inclined at an arbitrary height of the opening provided in the shutter shade and the exterior sunshade roller screen during opening and closing operation. Yes.

In Fig. 6, a small portion of the expansion width of the slotter screen 8s of Fig. 4 is fixedly disposed on the bottom support 22 of the slotter screen 8s of the shutter so as to be moved up and down, and the crutch 22 when positioned at a high place. To lower the slotter screen (8s).

Conventional shutters are used for nighttime security functions and to remove flying objects during heavy rains.However, in order to shade the sun at low altitudes, the slotter screen must be pulled down to a lower level, and the room is dark and the view is dark. Since the forced slotters are heavy and bad in appearance, they are not practical as shading means. And as shown in Fig. 6, the shutter is extended to install a sloped plane, and even when the sun is low in the sun, it is completely shielded, and further, the expansion winding of the slotter screen 8s is performed by the crutch 22 described above. Since it has such a high height that it is easy to handle, there is no need for the operation code as shown in FIG. 4 described above, and between both ends of the brackets 23 having fixed ends disposed on both ends of the wound slotter screen 8s, which are secured by the shoring 22. It is a very convenient structure because the elastic action to remove the slotter screen (8s) and shoring (22).

FIG. 7 is the same method as the shutter of FIG. 6, which is attached to the auxiliary rail 24 of the exterior sunshade roller screen 29 disposed outside the window, and the slotter screen 8s can be fixedly arranged to freely move up and down. have. The exterior sunshade roller screen 29 is fixed to the lower end of the storage case 26 and the cloth screen 27 for receiving the winding drum 25, the board rail 24 is guided slidingly to the longitudinal guide rail (28) ), And the structure to be wound as a force of the winding spring built in the winding drum 25 is the same as a well-known sunshade roller screen.

As described above, the slotter screen of the present invention is expanded into a plate by solid hinge bonding between adjacent slotters, and in addition to the bending stress in the longitudinal direction of the slotter, the compressive stress in the slotter length direction and the perpendicular direction is applied to the load in the out-plane direction. It is high strength because the distributed reaction force of stress is created and the curved surface slotter has smooth surface so that dirts such as cracks are not accumulated, and the expanded slotter eliminates the clearance gap of the hinge joint when the shutter is used as a shutter. It is effective in preventing the occurrence of metal noise due to the impact of the collision. Also, since the flat expansion is maintained in the horizontal direction without bending downward, complicated components such as the support rod are not required as in the prior art. It is very useful because it can bring convenience and cost reduction The.
