However, since the Young's modulus of synthetic resin is smaller than that of aluminum, it is difficult to avoid bending of the louver blade made of synthetic resin when the length is increased. For example, using a synthetic resin such as polycarbonate or ASA, the wall thickness is 2 mm, the length is 1 m, a louver product using a louver blade with a relatively long S-shaped cross section, and aluminum. In a louver product using a louver blade having the same length and the same cross section of 0.8 mm, the maximum deflection of aluminum is 0.28 mm in a test in which a wind pressure of 33.1 m / sec and a wind pressure of 82 kgf / m ² is applied. , Polycarbonate is 8.84mm, ASA is 9.73mm, which is the result that the amount of bending of the synthetic resin louver blade is extremely larger than aluminum, and the length is 1.2m, 1.5m, etc. If it is made so long, the result is that the amount of deflection further exceeds 10 cm.

  Such a large amount of bending causes a problem that the blindfold function is impaired if the louver blade is pressed or pulled by hand, and when the strong wind is received, the bent louver blades hit each other to generate noise. Therefore, if the louver blade is made of a synthetic resin or has a length of about several tens of centimeters, there is no particular problem. In order to produce a louver product having a width or height of about 1 m or more using a louver blade, it is necessary to prevent the occurrence of the deflection.

  In the following, the present invention will be described in more detail with reference to the examples of the drawings. In FIGS. 1 to 6, A is a fence using a synthetic resin louver blade 3 and having a ventilation function and a daylighting function in this example. It is a louver product, and the fence A is formed by supporting the blade 3 on an opposing support frame. In this example, the support frame is attached to an end of the fence A and an intermediate support 1. A plurality of louver blades 3 are fixed horizontally with screws 5 fixed to the pillars 1 so that both ends in the width direction, that is, upper and lower ends partially overlap, and are blinded so that no gaps penetrate between the louver blades 3. It has a function.

  At this time, the louver blade 3 includes a blade body 31 integrally formed of synthetic resin by extrusion molding and a deflection preventing bar 4 which is also integrally formed of aluminum by extrusion molding. And a fitting protrusion 35 and a fitting groove formed simultaneously on the bending prevention bar 4, respectively, by fitting the fitting portions 35 and 41 to each other over the entire length in the longitudinal direction at both ends in the width direction of the blade body 31. The bend prevention bar 4 is arranged.

  In this example, the blade body 31 is formed by extruding a transparent or translucent resin such as polycarbonate, ASA, acrylic or the like, and integrally molding the resin. At this time, when the transparent resin is used, A diffused reflection measure for irregularly reflecting light is applied to both the front and rear surfaces or one of the surfaces to provide a blindfold function. For example, as shown in FIG. In addition, after the extrusion molding, the blade body 31 is roughened partially or entirely by performing post-processing such as shot blasting or polishing for appropriate translucency.

  At this time, the blade body 31 has, for example, an S-shaped cross section including an inclined base portion 32 and standing ridges 34 that stand up at both ends in the width direction of the inclined base portion 32. That is, the blade body 31 of the present example has an inclined base portion 32 inclined at, for example, about 60 degrees, and upright ridges 34 are raised at both ends in the width direction of the inclined base portion 32, that is, upper and lower ends. In this example, the blade body 31 has a thickness of, for example, about 1.5 to 2 mm, and the uprights 34 are vertical. In the disposed state, for example, the width is about 10 cm, in this example, 11-12 cm wide, and the depth is about 5 cm, in this example about 4 cm.

  The joint portions 35 of the blade body 31 which are simultaneously formed are installed at the tip positions at both ends in the width direction of the blade body 31, particularly at either one of the front and rear surfaces of the tip position, or both the front and rear surfaces. It is assumed that they are installed separately at both ends in the width direction. At this time, in the blade body 31 of this example having an S-shaped cross section and standing ridges 34 at both ends in the width direction, the fitting portion 35 is placed on the front surface of the standing ridge 34 at one of the both ends in the width direction. By disposing it on the rear surface of the upright surface of the upright strip 34 at the other end in the width direction, it is assumed that fitting parts are installed separately at both ends in the width direction on both the front and rear surfaces.

  In this example, the fitting part 35 of the blade body 31 is formed by a fitting protrusion of the pair of fitting protrusions and fitting grooves, and in this example, For example, assuming that the joint ridge has a T-shaped cross section, in the present example, at both ends in the width direction, a protruding T-shape is projected on the rear surface of the standing ridge 34 at the upper end, and the standing ridge 34 is also formed at the lower end. In this case, the fitting portion 35 formed by the fitting protrusion having a T-shaped cross section is formed from the wall thickness of the blade body 31. In this example, the thickness of the anti-bending bar 4 to be described later can be surely and firmly engaged with the fitting portion 41 of the fitting recess, and the fitting portion 35 of the blade body 31 can be formed. The wall thickness of this is about several mm. For example, the protruding part from the standing surface is about 3 mm. There as about 2mm cross section intersecting the.

  In this example, the deflection preventing bar 4 is formed by, for example, extruding a JIS A6063 aluminum alloy used for a general aluminum product and integrally forming the aluminum alloy, so that the bending prevention bar 4 is opposed to the fitting protrusion of the fitting portion 35 in the blade body 31. In this example, the bending prevention bar 4 includes a tapping hole 42 for fixing a blade screw, which is simultaneously formed by the extrusion molding. As it was.

  At this time, the anti-bending bar 4 is formed of a thin bar material having an appropriate cross-sectional shape such as a rectangle, a rectangle, or an ellipse having a width of about 1 to 2 cm on one side. Is arranged on the contact surface with the blade body 31 as a fitting portion 41 by inverting the T-shaped fitting protrusion and forming a T-shaped fitting groove forming a groove having an opening on the facing surface side. In addition, the tapping hole 42 is arranged in parallel with the fitting recess at an intermediate position in the cross section, and the remainder is solid, and the deflection preventing bar 4 of this example has a width of about 1 cm, for example. The height of the end face opposite to the contact surface is lowered and the cross section is made to be rectangular with a rounded corner. Even if the anti-bending bar 4 is formed of such a thin bar material, the Young's modulus of the blade body 31 can be sufficiently improved and secured by being fitted to both ends of the blade body 31 in the width direction. Although it does not prevent the cross section from being enlarged, it is generally sufficient that the cross section is about 1 to 2 cm.

  The bending prevention bar 4 is arranged over the entire length in the longitudinal direction at both ends in the width direction of the blade body 31 by fitting the fitting portion 41 with the fitting portion 35 of the blade body 31. In the case of the blade body 31 of this example in which the fitting parts 35 are arranged at the tip positions at both ends in the width direction, particularly the front and rear surfaces of the upright strip 34 having an S-shaped cross section, this is used as the tip position of the blade body 31. Therefore, it is arranged on the front surface and the rear surface of the standing surface. Therefore, at the upper end of the blade body 31, the bending prevention is provided on the rear surface of the rising surface 34 and on the lower surface of the standing surface 34. Bar 4 is arranged.

  In order to dispose the deflection preventing bar 4 at both ends in the width direction of the blade body 31, particularly at the standing ridge 34, the fitting portion 35 of the blade body 31, particularly the fitting portion 41 of the fitting protrusion and the deflection preventing bar 4, particularly the fitting. The mating ridges may be fitted to each other by sliding the mating ridges facing each other at their longitudinal ends. At this time, for example, the mating ridges may be ground to some extent. The slide fitting can be facilitated by tapering and grinding the inside of the fitting groove to enlarge it.

  In the fence A of this example using the louver blade 3 formed in this way, the louver blade 3 is attached to the end portion and the intermediate strut 1 and one side of the adjacent louver blade 3 in the width direction, that is, the louver blade 3 is attached. In the fence A of this example arranged horizontally, the lower end of the upper louver blade 3 and the upper end of the lower louver blade 3 are sequentially arranged so as to overlap each other, and the deflection preventing bar 4 of each louver blade 3 is respectively arranged. The screw 5 is screwed into the tapping hole 42 formed on the support column 1 through the through hole formed in the support column 1 and is fixed to the support column 1 at both ends in the longitudinal direction and at both ends in the width direction. It is sufficient to perform the assembly by forming the fence A as a fence A, thereby eliminating the bending and ensuring the high Young's modulus. Although the prevention bar 4 exists at the rear surface at the upper end of the louver blade 3 and at the front surface at the lower end, the prevention bar 4 is disposed opposite to the front and back of the standing ridges 34 arranged so as to overlap with each other. 4 can be prevented from being exposed to the appearance of the fence A, and the anti-bending bar 4 can be disposed to improve the appearance and to maintain the ventilation function and the daylighting function, and also to ensure the blinding function. . In the figure, reference numeral 2 denotes a horizontal frame constructed and fixed between the end portion and the intermediate support column 1.

  FIGS. 7 to 10 show louver blades 3 according to other embodiments and examples of their arrangements. FIG. 7 shows a blade body 31 formed in a flat plate shape. 31 are arranged at both ends in the width direction, in this example, at the upper and lower ends, to form a louver blade 3, and the louver blade 3 is arranged in a staggered manner at the end and intermediate strut 1. FIG. 8 shows an example of a fence in which the louver blade 3 is inclined so that the upper and lower ends thereof partially overlap. FIG. 9 shows that a plurality of flat plate-like blade bodies 31 are used and arranged in the middle. Then, by providing a fitting portion matched to both blade bodies 31, it is connected in an inverted V shape via an intermediate connecting bar 36 integrally formed by extrusion molding in accordance with the above-described deflection preventing bar 4, and its width direction At both ends FIG. 10 shows an example in which a louver blade 3 is formed by disposing a flaking prevention bar 4 and disposed between the end portion and the intermediate strut 1 so that the upper and lower ends of the louver blade 3 partially overlap each other. The main body 31 is provided with a vertical base portion 37 and bent portions 38 at both ends in the width direction protruding horizontally from the vertical base portion 37 so as to have a U-shaped cross section. 3 is similarly arranged between the end portion and the intermediate strut 1 so that the upper and lower ends of the louver blade 3 partially overlap each other. Since the rest is the same as the above example, duplicate explanations are omitted, but all have a ventilation function, a daylighting function and a blindfold function as in the above example, and each has a high Young's modulus and an excellent strength. can do.

  As described above, the cross-sectional shape of the blade body 31 and the arrangement form of the deflection preventing bar 4 with respect to the blade body 31 can be variously changed. However, the Young's modulus differs depending on the sectional shape and the arrangement form of the deflection preventing bar 4. There is a possibility that will occur. In particular, the blade body 31 having an S-shaped cross section and a U-shaped cross section is combined with the cross-sectional shape to form a louver blade 3 having a higher Young's modulus than a flat plate-shaped one. Therefore, the arrangement pitch of the support frames can be further expanded. Further, the anti-bending bar 4 is higher than the one shown in the figure or figure in which the upper end is arranged in a cap shape, as shown in FIGS. The thing which exhibits a Young's modulus, and the thing arrange | positioned in the bending strip 38 like FIG. Therefore, among these, the examples of FIGS. 1 to 6 and the example of FIG. 10 are preferable. However, from the viewpoint of securing the ventilation function and designability, the former examples of FIGS. 1 to 6 are used. More preferably.

  Although the illustrated example is as described above, the fitting portion of the blade body is a fitting recess, the fitting portion of the anti-bending bar is a fitting protrusion, and the blade body is perpendicular or inclined to the middle in the width direction of the blade body. In order to prevent the occurrence of dirt due to intrusion of rainwater, invasion of micro-insects, etc., in order to prevent the occurrence of dirt, etc. To ensure water tightness, to place the louver blades vertically by supporting the louver blades on the upper and lower support frames, and to install the above-mentioned standing or bending ridges at the base In carrying out the present invention, including appropriately setting the protrusion angle with respect to the blade body, a deflection preventing bar, a fitting portion in which a fitting protrusion and a fitting recess are paired, a louver blade Each specific shape, structure louver products or the like using the louver blade, material, these relationships, addition or the like for these may be of various forms unless contrary to the gist of the invention.
