Description

[Detailed Description of the Invention] [Technical Field] This invention relates to a louver for a lighting fixture.

[Background technology]

A conventional example is shown in FIGS. 1 and 2. That is, 1 is a lattice-like louver body formed by combining louver pieces 2 and 3 having a substantially V-shaped cross section in a lattice shape, and 4 and 5 are side louver pieces, which are fixed to the upper and lower ends of the louver pieces 2 and 3. The claws 6 are extended, corresponding slit holes 7 are formed in the side louver pieces 4 and 5, and the locking claws 6 are passed through the slit holes 7 and bent to assemble the two.

However, since the assembly work involves inserting the locking claws 6 of the louver pieces 2 and 3 into the slit holes 7 and bending the locking claws 6 while bringing the louver pieces 2 and 3 into close contact with the side louver pieces 4 and 5, it is difficult to work. The drawback was that it was bad. Moreover, for this reason, gaps are likely to occur between the louver pieces 2, 3 and the side louver pieces 4, 5, which impairs the appearance and light distribution.

[Purpose of invention]

Therefore, an object of this invention is to provide a louver which can be easily assembled and whose louver pieces and side louver pieces can be brought into close contact with each other.

[Disclosure of invention]

In this invention, a plurality of louver pieces bent into a substantially V-shaped cross section are assembled in a lattice shape, and locking notches are formed downward at the lower bent portions of the ends of the louver pieces arranged in at least one direction. A lattice-shaped louver body with a pair of locking claws extending from the upper end edge of each louver piece, and a lattice-shaped louver body disposed on the side of the lattice-shaped louver body, with a cross section consisting of a wide part and a narrow part. A side louver that is approximately J-shaped and has a fitting cutout facing upward on the wide part side into which the louver piece is tightly fitted, and a hooking claw corresponding to the locking claw is formed at the edge of the fitting notch. an engaging slit is formed at the intersection of the locking notch, the fitting notch, and the narrow width portion, and the intersection of the locking pawl and the hooking pawl; It is characterized in that the locking pawl is bent. The louver piece and side louver piece are tightly engaged due to the engagement of the locking pawl and the hooking pawl, and the engagement of the fitting notch and the narrow part and the locking notch, and the bending of the locking pawl ensures secure fixation. be done. Moreover, it is easier to assemble since there is no need to bend the locking pawl while making a close contact compared to the conventional method.

An embodiment of this invention is shown in FIGS. 3 to 6. That is, 8 is a grid-like louver body, and 9 and 10 are side louver pieces. The lattice-like louver body 8 has a cross section of approximately V
Horizontal louver piece 11 and vertical louver piece 12 forming a character shape
The intersecting parts are interlocked with each other by notches (not shown).
At the end of the vertical louver piece 12, a locking notch 13 is formed at the lower bent portion such as the fourth portion, and engaging slits 14, 14' are formed on both sides of the bottom of the locking notch 13.
Locking pawls 15, 15' extend from the upper end of the pair of edges, and engaging slits 16, 1 are provided at the bottom of the base.
6' and further tilts the lower edges of the locking claws 15, 15' into the engaging slits 16, 16'.
7, 17' (Fig. 5). Further, the end of the horizontal louver piece 11 has a bent portion at the lower end extending outward to form a protruding portion 18, and an engaging slit 19 on the upper edge side.
, and locking claws 20, 2 are formed on the upper end side of the pair of edges.
0' and an engaging slit 21 on the upper edge side thereof.
21'.

The side louver pieces 9 and 10 have a wide part 22 and a narrow part 23.
The side louver piece 9 with respect to the horizontal louver piece 12 has a wide part 22 as shown in FIG.
A fitting notch 24 into which the horizontal louver piece 12 is inserted is formed, the bottom of which is approximately at the same height as the upper edge of the narrow part 23, and meshing slits 25, 25', of the same shape are formed in the bottom and the narrow part. 26, 26' are formed, and the intermediate portion thereof is inclined in a mountain shape to form guides 27a, 27b. Furthermore, hooking pawls 28, 28' extend from the upper edge of the fitting notch 24, and engaging slits 29, 29' are formed above the bases thereof. Further, the end of the side louver piece 9 has a lower bent portion extending outward to form a protrusion 30, and an engaging slit 3 at the upper edge thereof.
1, a hooking pawl 32 is formed on the upper end side of the edge, and an engaging slit 33 is formed on the upper side of the base.

The side louver piece 10 corresponds to the end of the vertical louver piece 11, and has a locking hole 34 and meshing slits 35, 35' formed in the locking claws 20, 20'. Locking notch 3
6 is formed, and engaging slits 37, 37' are formed. The end of the side louver piece 10 forms a locking notch 38 and engaging slits 39, 39' with respect to the engaging slit 31 at the end of the side louver piece 9, and a locking pawl 40 with respect to the hooking pawl 32. is formed, and an engaging slit 41 is formed on the lower side of its base.

The assembly will be explained. A lattice-like louver body 8 is formed by stacking a horizontal louver piece 12 on a vertical louver piece 11,
Hook the locking claws 15, 15' of the horizontal louver piece 12 into the hooking claw 2.
8, 28, and the locking notch 13 is engaged with the narrow part 23 and the narrow notch 24 of the side louver piece 9, and the engaging slits 16, 16', 28, 2
8' mutual and interlocking slits 14, 14', 2
5, 25', 26, 26' are engaged with each other. Then, the locking claws 15, 15' are bent outward and fixed (FIG. 6). The locking holes 34 of the side louver pieces 10 are engaged with the locking claws 20, 20', the locking notches 36 are hooked onto the protrusion 18, and the engaging slits 19, 37, 37',
21, 21', 35, 35' are engaged. In addition, the locking claw 40 at the end is hooked onto the hooking claw 32, and the notch 38 is hooked onto the protrusion 30 to open the engaging slits 31, 39, 3.
9', 33, and 41 are engaged, and the locking pawl 40 is bent.

With this structure, assembly can be accomplished simply by inserting the horizontal louver piece 12 into the side louver piece 9 from above, and the engaging slits 16, 16', 29, 29',
Precise assembly is maintained by 14, 14', 25, 25', 26, 26', adhesion is ensured, and fixation is ensured by bending the locking claws 15, 15'.

Note that the coupling structure between the side louver piece 10 and the vertical louver piece 11 may be the same as the coupling structure between the side louver piece 9 and the horizontal louver piece 12.

[Effect of idea]

As described above, the invented louver has the advantages of easy assembly, good dimensional accuracy, and no gaps.
