Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting louver used for adjusting a light quantity and shielding a light source, and a method for manufacturing the same.

[0002]

2. Description of the Related Art Conventionally, a louver of this kind is provided with a long slit made of metal or plastic and provided with locking slits, a plurality of such slits are arranged in parallel and arranged in a comb-tooth shape, or intersect vertically and horizontally so that the slits mesh with each other. And were arranged in a lattice.

[0003]

The conventional louver is constructed by combining a plurality of blades, so that it takes time to assemble the louver. Also, such as incorporating a louver between the laminated glass plates, when forming a dimming plate or window frame integrally mounted louvers, each blade of the louvers are engaged with each other through a slit, In addition, in the case of a thin louver having a small width, the slit is inevitably shallow, so that when the louver is incorporated, the blades are disengaged from each other and are easily disassembled. Above all, the thin louvers used in such applications have disadvantages such as low strength because the blade plate is thin and small in width, and it is easy to bend when slits are formed by punching.

In view of the above problems, the present invention eliminates the trouble of assembling the blade by integrally forming the louver, is easy to handle, and easily performs secondary processing such as incorporating the light control plate. It is an object of the present invention to provide a lighting louver that can be used and a manufacturing method thereof.

[0005]

In order to solve the above-mentioned problems, a lighting louver according to the present invention has a large number of openings arranged in a single plate, and at least one of vertical and horizontal lattice portions between the openings. One of the lattice portions is repeatedly bent, and the direction of the other lattice portion is formed to be inclined or perpendicular to the single plate surface. According to the present invention,
A grid that defines the opening is juxtaposed with the opening in an inclined state,
By appropriately setting the inclination angle of these gratings, it can be used as a louver for adjusting the light amount, the light source shielding angle, and the like, and since each blade is integrally formed,
No need for blade assembly, easy handling,
Secondary processing can also be easily performed.

The lighting louver is formed by punching a single metal plate to form a large number of openings in parallel, and at least one of the vertical and horizontal lattices left between the openings. Pressing and bending repeatedly, and manufacturing by bending the other lattice portion intersecting with the bending process to be inclined or perpendicular to the single plate surface in accordance with the bending process. Can be. The punching step and the bending step may be configured as one step.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described with reference to the drawings. In FIG. 1, reference numeral 1 denotes a louver of the present example, which is made of a metal material such as aluminum or stainless steel and is formed by punching a plate having a thickness of about 0.5 to 1 mm and extending in a longitudinal direction. A group of vertical blades 2 and a group of lattices extending in the horizontal direction perpendicular to the horizontal blades 3 are defined as horizontal blades 3. Both blades define a large number of elongated rectangular openings 4 arranged vertically and horizontally. Mountain folds and valley folds are repeatedly formed, and the vertical blades 2 are inclined with respect to the plate surface to form a thin corrugated plate as a whole.

More specifically, each of the blades has a width of, for example, about 5 mm, and as shown in FIG. A large number of horizontal blades 3 are arranged in parallel at appropriate intervals L wider than the vertical blades 2, for example, at intervals of about 95 mm.

As shown in FIGS. 1 and 2, the horizontal blade 3 has a folded portion 5a at an intersection with each vertical blade 2 on an extension of the left side of the vertical blade 2 or on the left side thereof, and a right side. Are provided on the extension line of the right side or on the right side thereof, and are repeatedly bent in a wave shape by being mountain-folded at the above-mentioned folded portion 5a and valley-folded at the above-mentioned folded portion 5b, and each vertical blade 2 is made to have the same angle according to the above-mentioned folded portion. It is formed so as to be inclined to the lower right. In this example, the vertical blade 2 is set at about 75
The bent portions 5a and 5b of each of the horizontal blades 3 which are inclined at an oblique angle of .degree. Although not shown, it is preferable that the outer peripheral edge of the formed louver 1 is surrounded by a horizontal flange having an appropriate width in order to stabilize the shape.

The above-mentioned dimensions of the louver 1, such as the width, arrangement interval, and thickness of the two blades, can be appropriately selected according to the intended use, the mounting location, and the like.
Can be set as appropriate. For example, as shown in FIG. 3, the bending angle of the horizontal blade 3 with respect to the plate surface is 30 ° (FIG. 3A), 45 ° (FIG. 3B), and 60 ° (FIG. 3C). , 90 ° (FIG. (D)). Further, as shown in FIG. 4, the horizontal blades 3 are arranged as if they were jointed with bricks, and the openings 4
May be formed so as to appear staggered. The surface of the louver 1 can be appropriately colored or coated with a resin.

The louver 1 of this embodiment having the above configuration can be manufactured by the following procedure. That is, first, a single plate is punched out sequentially by a press machine, and a large number of rectangular openings 4 having, for example, a length (L) of 95 mm and a width (D) of 10 mm are arranged in rows and columns. The vertical and horizontal blades 2 and 3 of 5 mm are left, and at the same time or thereafter, the horizontal blade 3 may be repeatedly press-bent in a wave shape as described above. At this time, the vertical blade 2 may be in a free state, or may be in contact with a mold portion inclined at a predetermined angle.

The punching of the opening and the bending of the blade can be performed with the same mold, or can be performed continuously with separate molds. Further, processing by other devices, such as processing by passing a plate between rolls formed to allow punching and bending, is also possible.

According to the louver 1 of the present embodiment formed as described above, the folding angle of the horizontal blade 3 is appropriately selected, and each vertical blade 2 is appropriately inclined with respect to the plate surface, so that the light amount and the light source It can be directly mounted on ceilings, walls, windows and other lighting places to adjust the perspective angle. In addition, by providing both blades with a small width and providing the entire louver thinly, the louver 1 can be incorporated between the laminated glass plates to form a thin light control plate or the like in which the louver 1 is integrally mounted.

Since both blades crossing vertically and horizontally are integrated,
The conventional assembling work for engaging the blades with each other is unnecessary, the blades do not separate during handling, and since the louver 1 is formed in a corrugated plate shape, even if the blades are provided in a small width. There is no danger that a part of the louver 1 will be deformed during handling and will not be easily bent.
It is easy to handle and can be easily processed when forming the light control plate.

[0015]

As described above, according to the lighting louver of the present invention, since each blade is formed integrally, the trouble of assembling the blade is unnecessary, the handling is easy, and the secondary processing can be easily performed. . Further, according to the method for manufacturing a lighting louver of the present invention, it is possible to form a louver integrally provided with blades crossing vertically and horizontally.
