Description

V. Description of the invention (1) The technical field to which the invention belongs B The present invention relates to a slatted screen used for a rolling door or a sun-shading shutter arranged at an opening of a building. / Known technology In the past, this type of rolling door was made of a slat screen connected to a plurality of steel battens. However, since it cannot be horizontally expanded, it is generally used for a sunshade screen. The awning of the rolled curtain. Furthermore, this conventional rolling door is provided with a cylindrical hinge having a slit-shaped cross-sectional shape on both sides of the slat constituting the rolling door. This board is like a cylindrical key, that is, the hinge on one side is introduced into the outer periphery of the hinge cylinder of the other from the opening, and is inserted and fitted into the same through the incision, so that they can rotate freely in two directions outside the plane. Therefore, the screens of the battens connected in this way constitute a chain. When the invention desires, the out-of-plane directions converge to each other. In addition, due to the weight of each strip, and the problem solved by the screen, in the above known person, the concentric circular fitting of the hanging lower plate from the roll screen to the self-roller expansion no longer exists, but in the up and down direction and A play occurs. Due to the clearance, the inner and outer cylinders of the cylinders of each slab collide with each other and metal sounds occur, which further becomes the voice. If the slatted slab screen is subjected to external pressure loads such as wind pressure, the clearance between the slabs The squeaking noise occurred, and after the bending and solid clearance of each board was eliminated, it became integrated with the adjacent board to resist the overall deflection of the outer curtain, and each board needed to be fixed.

Page 5 One side of the pole, and the other side with a freely retractable and free wall surface is aged and easily deteriorated, so it is not easy to construct not only a plurality of roller blinds, etc., but also the south wall surface. V. Description of the invention (2) Therefore, the bending strength is strengthened, but the dust and dirt are wound around the roll and it is shaped into a fan, and the multiple curved wrists are connected, and the center of the spring laid on the rack, but made of cloth rolls is loose, and points. In addition, heavy objects caused by the winding structure are expensive. 405014 degree problem point It is suggested that in addition to the disadvantages of accelerated dyeing on the slat screen, the opening and closing of the shape of the funnel mouth is hidden from the surface of the cylindrical hinge, which is harmless. In addition, during operation, a metal male screen also occurred, the wrist rod and the spool supported by the water pivot broke, and in addition, the accumulated rainwater could be expanded, and the installation and application of the curved rod and multiple components caused logarithmic logarithm. The concave and convex part has a continuous sound. The σ part is respectively supported by the flat support. If the curved screen is supported and the external knot is bent, the cost of the slab surface is curved convex line, and there is a contact on the slab screen roll due to the attached line. The point of the vertical guide. The upper end wall is respectively hinged with horizontal support rods. The flat-bone fabric rolling shutters formed by the pivot rods are bent, and the curved rods are tightened in the direction of expansion. In addition, because the sunshade screen is fixed to the upper end wall of the opening, the sunshade screen must be protruded deeply until the lower end of the opening is blocked according to the height of the sun. The deeper the projection width, the larger the moment acting on the wall surface side of the curved support arm, and the rigidity of the mounting wall surface is also required. In addition, when the roll-up door is opened to block light, the indoor illumination is reduced and darkened, which is not only dull, but also requires the roll-up door to be almost fully closed in order to completely cover the setting sun with low sun height. Shading is not practical and has limited use.

Page 6 5 'Explanation of the invention (3) 40501 ‘thus’ the present invention is an improvement of the above-mentioned conventions to prevent noise and can be used for rolling doors and coverings: it is to provide a structure that can be used for both. Means to solve the problem Panel screen: And the edge of the strip is connected to the curved western section of the plurality of strips on the two ends of the strip to form a slit-like open portion of each other to form a face of Yanxian; The zigzag outer curve 2 extends and is perpendicular to the tangent of the outer perimeter of the slat. The outer perimeter and the planes that are substantially parallel to the above-mentioned plane are connected to form a narrative chain. The hinges of the adjacent slabs extend the concave and convex portions of the three-shaped perimeter. Combined and fitted together, and when each plate is in a self-winding state = open in a straight line, the convex surface and concave surface of the curved surface surrounded by the outer surface stop, and the flat jaw becomes the fulcrum of the lever; The screen is covered to be freely disassembled and used as a sunshade roller curtain. In addition, the end strip is fixed at the bottom rail of the screen, or the sunshade roller curtain, and the screen is laid in two directions in the horizontal direction. The embodiment of the histogram invention The present invention has the above-mentioned structure. Therefore, in the implementation, 'the gap between the slabs is solved at the connection portion of each slab without noise, and it is unfolded as a whole with the adjacent slabs' Therefore, it can fully resist external forces such as wind pressure. At the same time, it is developed into a slanted surface because it is an adult, and it can also be used as a sunshade roller blind. Moreover, the structure is simple and the cost can be reduced. In addition, the structure of the battens is not limited to steel, aluminum, etc.

Description of the invention (4) — _ — — __, metal extruded components, the double-structured screen is also made of synthetic m-shaped, and the battens and waterproof coating film can also be formed: two non-woven fabrics, and If necessary, apply it to the surface to prevent rainwater from penetrating. EXAMPLES Know more in detail according to the figure # H 日; ~ plate, forming a curved circle ϊ = embodiment of the invention. The estimated thickness of the slat thickness between 8 series extruded strips: ㈤ and / Curve® R1 and the inner curved surface with B. The hinges A and B each have a ruler gap f ^ to form the hinges A and V: and they are opposite to each other with respect to the curved circumferential curved surface to form an s sub-shape S2. Adjacent strips 8 are surrounded by S-shaped curved surfaces SI, S2. Ϊ́ Γ: The two-two-two recessed portions lb'2b have a small gap and hug each other to form a cross-section that is self-cut and enclosed. The extension of one side tangent of the convex part 1 a of the three sub-shaped curved surface S1 of the hinge A constitutes a straight line part 3 a ′ and a concave arc 4 a centered on the convex point 1 & the center point 10 of the curved surface, ..., , The concave curved surface 4 a and the flat jaw 5 "" knife tangent to the outer curved surface R1 of the batten. The hinge of the figure 8 of the hinge" is held in the convex part 2a of the drum key, and the batten 8 is straight The expanded state is formed as deep as the bending rotation degree Θ, and @ 时 is tangent to the arc on the outer circumference of the convex part ^ of the hinge B and the inner surface R 2 of the slab. The side tangent line extension 3b of the concave portion of the S-shaped curved surface S2 of the hinge B is tangent to the concave arc 4b having a radius centered on the center point 10 of the concave portion ib surface, and the concave curved surface 4b and The plane jaw 5b perpendicular to the tangent of the outer peripheral surface of the slab is phase w. The center of the plane of the hinge A is parallel to the plane. Compared with the outer periphery of the convex portion 2a of the S-shaped curved surface 52 of the chain B,

Page 8 V. Description of the invention (5) 405014 ~~ --- The center point of the part lb〗 0 is a concave arc with a radius r3 of the center and the inside of the strip 2 is connected. On the inner peripheral surface side of the curved strip 8, σ tongue portions 6 a and 6 b branched from the hinge a ′ B are formed, and these tongue portions are used to form a flat c-shaped cross section = f 7. The strip 8 having the cross section is convex as surrounded by S-shaped curved surfaces si, S2. ′ 1 a and recess 1 b are fitted to each other to be bent and rotated freely, and adjacent bars are bent and rotated at the maximum angle Θ, and the hinges A and δ are not separated from each other. When the plate 8 expands horizontally into a straight line from the rolled state, the hinges A, β of & 2 1 a and the recess 2 b are hooked, and the flat jaws 5 a and 5 b serve as lever fulcrum phases, and each of the plates 8 The adjacent bars are supported by compressive stress to each other, so that the plane can be continuously maintained in a linear shape. The bending west stress acts on the short distance between the fulcrum points of hinges A and β. However, because of the short fulcrum distance, it can fully bear the bending stress, and the reaction force when horizontally supporting each strip 8 is taken along the strip from the flat jaws 5a, 5b. The compressive stress of the curved surface of the plate is transmitted and balanced. 2. The permissible compressive stress of general metals or resins is a strength that is several times the allowable bending stress. Due to the load of most of the compressive force transmitted to the gate-type bending body other than the chain link of the batten, the compressive force will be continuous by the batten The screen of the screwed strip board cantilevered in the air and spreads horizontally in the air without bending greatly downward, but has the strength to maintain a flat surface. Next, an example of a product using a batten screen of the present invention will be described.

Compared with the conventional sunshade roller blind (awning) described above, the cost can be greatly reduced, and it can be used with relatively simple operations. ^ Figures 6 and 7 show the slat screen fixed to the wall as shown in Figure 4. The screen is installed on the rolling door and the sunshade roller blind is opened and closed in the up and down direction. The inclined plane is laid at any height of the opening. Examples. In FIG. 6 'the one with the small expanded width of the slat screen 8s of FIG. 4 is fixed to the lowermost horizontal plate 22 of the slat screen of the roll door, and is installed to move up and down freely, even if it is located at a high place. After pulling the horizontal plate 22 downward, the slat screen can be expanded for 8s. Generally, the “rolling door is used as an anti-theft function at night and a function to block flying objects during a storm”.

Page 11 4050 " Description of the invention (8) 5 The screen is pulled down to the very bottom, because not only the room darkens, but also the view is blocked, and the steel slot has a bulky appearance, so it is not practical for shading. Therefore, as shown in Fig. 6, after a part of the rolling door is opened, the sun with a low height under the laying inclined plane can be completely covered. In addition, the expansion and rewinding operations of the slat screen 8s can be reduced to the height of the horizontal plate and the hand by manual operation. Therefore, the operation cable shown in FIG. 4 is not required, and the spring is used to move the screen.
