And a blade support bracket 3 that fixes the inclined blade 2 to the rectangular frame 1, for example, for blindfolding that provides lighting and ventilation by being installed on an inclined ground using a support column 15. In this example, the ventilation louver A is arranged such that a single rectangular frame 1 is divided into left and right, and the inclined blades 2 are arranged in two in the left and right direction, and a support column 15 is used. In the inclined ground installation, the ventilation louvers A are arranged in two upper and lower stages.

  The rectangular frame 1 is made of, for example, an aluminum frame that is made of an aluminum material that is made of an extruded material, and is made of an aluminum material that can be tilted and rotated by pivotally fixing an upper and lower horizontal frame 11, a left and right vertical frame 12 and an intermediate vertical frame 13. In this case, the rectangular frame 1 has a larger expected width of the upper and lower horizontal frames 12 and a smaller expected width of the left and right vertical frames and the intermediate vertical frame 13, and the expected width of the inclined blades 2 is the upper and lower horizontal frames. In this example, the vertical frames 12 and 13 are pivotally fixed to the left and right end portions of the rectangular frame 1 so as to be pivotable and fixed to the left and right vertical frames 12. And the intermediate vertical frame 13 are arranged, and the two inclined blades 2 are arranged between the left and right vertical frames 12 of the rectangular frame 1 and the intermediate vertical frame 13.

  The inclined blades 2 are a plurality of parallel blades that are inclinedly arranged between the upper and lower horizontal frames 11 of the rectangular frame 1 in the expected direction. In this example, the inclined blades 2 are arranged on the blade substrate 21. It is assumed that the deflection preventing bars 25 are arranged at the upper and lower ends of the blade substrate 21. At this time, the blade substrate 21 of this example and the deflection preventing bars 25 at the upper and lower ends thereof are respectively formed on the blade substrate 21 using an extrusion molding material. The synthetic resin is made of aluminum so that the bending prevention bar 25 is excellent in rigidity, and the bending prevention bar 25 is provided with a tapping hole 29 for receiving a screw.

  In this example, the blade substrate 21 is made of a translucent material which is extruded by using a synthetic resin such as polycarbonate or ASA and bent at a fine pitch so as to have a blinding property. The bar 22 is formed as a flat plate integrally formed, and the deflection preventing bar 25 is paired with the above-mentioned mating ridge 22 and tilted back and forth after the mating so as to be closely fitted and fitted to each other. The fitting recess 26 is formed in a bar shape having the same length as the blade substrate 21 integrally formed.

  At this time, the fitting protrusion 22 of the blade substrate 21 of this example and the fitting protrusion 26 of the deflection preventing bar 25 are slidably fitted to each other so that the fitting protrusion 22 is moved back and forth with respect to the fitting groove 26. The loose-fitting bar 25 is fixed to the blade support bracket 3 and the deflection-preventing bar 25 is forcibly rotated in the front-rear direction. In this example, the bending prevention bar 25 is forcibly rotated in the front-rear direction and tilted with respect to the blade substrate 21. As will be described later, the fixing position of the deflection preventing bar 25 of the blade support bracket 3 is set to a position displaced up and down and up and down of the blade substrate 21 as will be described later. Place They are to perform their tilting arrangement by fixing to deviate.

The upright pieces 24 projecting from the front and rear ends of the blade substrate 21 are provided with, for example, parallel and vertical shapes so as to exhibit an upside-down or downside-down cross-section C shape. This facilitates the fitting work.

  At this time, the fitting recess 26 of the anti-bending bar 25 has a wide-mouth opening that opens in a wide-angle direction toward the front-rear tilt direction at a position displaced to the front-rear side so as to pass through the upper and lower ends of the blade substrate 21. 27 and the loose fitting space 28 for loose fitting of the fitting ridge 22 that is expanded in the front-rear direction from the wide opening 27 inside.

  That is, by performing the slide fitting, the fitting ridge 22 is loosely fitted in the loose fitting space 28 of the fitting groove 26, and the deflection is fixed by fixing the displacement position of the deflection preventing bar 25 to the blade support bracket 3. The prevention bar 25 is forcibly rotated and inclined so that the V-shaped projecting piece 23 of the fitting protrusion 22 on the blade substrate 21 stands on the inner upper end of the loose fitting space 28 in the bending prevention bar 25. The pieces 24 come into strong contact with the inner lower end and the inner wall surface of the loose fitting space 28 so as to perform the tight fitting, so that the anti-bending bar 25 moves the blade substrate 21 forward and backward at the upper and lower ends. The blade substrate 21 is clamped in the direction to eliminate the bending of the blade substrate 21 against an external force such as wind pressure, so that a high Young's modulus can be secured.

  On the other hand, the blade support fitting 3 is provided with a vertical frame fixing piece 31 and a blade fixing piece 32 in a plane L shape, for example, a metal or synthetic resin made of a bent product of a steel plate such as an extruded material of aluminum or synthetic resin or stainless steel. In the present example, the vertical frame fixing piece 31 and the blade fixing piece 32 are arranged at right angles and the vertical frame fixing piece 31 is formed into a plate having an appropriate shape such as a rectangle. The blade fixing piece 32 protrudes from one edge of the vertical frame fixing piece 31 toward the inclined blade 2 side, that is, forward, and the lower side is widened so as to cover the end surfaces inclined forward and backward of the inclined blade 2; In this example, the lower end of the plate is elongated so as to protrude downward from the vertical frame fixing piece 31, for example, a plate shape having an appropriate shape such as a triangular shape. At this time, the vertical frame fixing piece 31 and the braid A through hole is provided in each plane of the fixed piece 32, and the through hole is a through hole for a shaft support arranged at a single location in the in-plane intermediate portion of the vertical frame fixed piece 31, and the blade In the fixing piece 32, there are through holes for fixing the screw of the deflection preventing bar 25 arranged at two locations in the longitudinal direction, that is, both ends in the vertical direction.

Screws 34 from the through-holes, that is, tapping screws, are screwed into the tapping holes 29 of the anti-deflection bar 25 forming the expected surface at the end of the inclined blade 2 in the longitudinal direction, and the anti-deflection bars at the upper and lower ends of the blade substrate 21. By fixing 25, the forcible rotation of the anti-bending bar 25 and the inclined arrangement with respect to the blade substrate 21 by this are performed, and the tight fitting of the fitting protrusion 22 and the fitting recess 26 is performed. It is like that.

  The ventilation louver A is constructed by arranging a large number of inclined blades 2 in the rectangular frame 1 using the blade support bracket 3.

For example, the rivet 33 is fixed to the locating surface so as to be pivotally supported, and the blade fixing piece 32 is attached to each inclined blade 2, in particular in the longitudinal direction of the upper and lower ends of the blade substrate 21. It is assumed that the inclined blades 2 are supported by fixing the screws 34 to the upper and lower two places of the end portion, and thereby, approximately equal to the expected width of the upper and lower horizontal frames 11 with the expected width increased. Between the upper and lower horizontal frames 11, the inclined blades 2 are inclined in the expected direction with the intermediate vertical frame 13 interposed therebetween so that a large number of them are parallel to each other so as to form two stations in the left-right direction. In the manufacture of the ventilation louver A, the blade support bracket 3 is fixed by, for example, fixing the blade support pieces 3 by fixing the blade fixing pieces 31 to the anti-deflection bars 25 at the upper and lower ends of each inclined blade 2 in advance. It is easy to prepare a large number of inclined blades 2 and assemble the vertical frame fixing pieces 31 of the blade support bracket 3 so as to be pivotally fixed to the left and right vertical frames 12 and the intermediate vertical frame 13.

  In the figure, reference numeral 14 denotes an end cover disposed on the front side of the left and right vertical frames 12 and the intermediate vertical frame 13.

  The ventilation louver A formed in this way is formed by tilting the rectangular frame 1 with the left and right vertical frames 12 and the intermediate vertical frame 13 pivotally fixed to the upper and lower horizontal frames 11 so that the rectangular frame 1 is inclined. On the other hand, the blade support bracket 3 is configured such that a large number of parallel inclined louvers 2 arranged in the rectangular frame 1 are pivotally fixed to a left and right vertical frame 12 and an intermediate vertical frame 13 with a vertical frame fixing piece 31 rotatably supported. By fixing the screw 34 to the blade fixing piece 32, the inclination of the rectangular frame 1, that is, the inclination of the left and right vertical frames 12 and the intermediate vertical frame 13 can be inclined and rotated in the longitudinal direction of the inclined louver 2 in the same manner. Therefore, when this is installed on a sloping ground using, for example, the strut 15, that is, a strut having the same length, the rectangular frame 1 is tilted and rotated in accordance with the slant of the sloping ground, and a large number of parallel sloping blades 2 are formed in the rectangular frame 1. Simultaneously following the tilt rotation of It is possible to tilt pivot, which vent air louvers A be placed on sloping ground or the like may be, it becomes that may make better its installation without discomfort appearance.

  The illustrated example is as described above, but without using the intermediate vertical frame, the left and right vertical frames are pivotally fixed to the upper and lower horizontal frames to form a single-section rectangular frame, and the blade support Use a bracket to make a number of parallel inclined blades fixed to the left and right vertical frames of the rectangular frame, increase the prospect of the left and right vertical frames or this and the intermediate vertical frame, and The vertical frame fixing piece is rotated with respect to the left and right vertical frames or a parallel surface parallel to the finding surface of the intermediate vertical frame, for example, a fixing protrusion formed at an intermediate position in the expected direction, and a rear surface formed at the rear in the expected direction. For example, the blade fixing piece of the blade support bracket is provided with a bent portion at the tip of the blade fixing piece, and the bent portion extends from the bent portion to the end surface in the longitudinal direction of the inclined blade. On the other hand, fix with appropriate fixing means such as screws and adhesives.
