Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a louver used in lighting equipment and the like.

[Conventional technology]

FIG. 4 is a perspective view showing a conventional louver joint structure disclosed in, for example, Japanese Utility Model Application Publication No. 59-85504. In the figure, 1 is a vertical louver material with a substantially V-shaped cross section, 2 is a horizontal louver material that has the same cross-sectional shape as this vertical louver material and is joined to the vertical louver material so as to be substantially orthogonal to the vertical louver material, and 3 is a horizontal louver material. This is an engaging portion that joins these together. FIG. 5 shows the engaging portion 3 of these louver materials 1 and 2.
In the exploded cross-sectional view of , 4 is the notch of the horizontal louver material 2;
Reference numeral 5 designates a locking portion thereof, and 6 designates a locking portion of the vertical louver material 1.

The conventional louver is constructed as described above, and the louver is assembled by inserting the vertical louver material 1 into the notch 4 of the horizontal louver material 2 and connecting the locking portion 5 with the locking portion of the vertical louver material 1. 6 is locked and held.

FIG. 6 is a perspective view showing another conventional louver joint structure disclosed in Japanese Utility Model Application Publication No. 60-71009.
This louver has locking claws 7a and 7b formed on both sides of the upper end of a vertical louver material 1 having a substantially V-shaped cross section, and these are inserted into locking portions 8a and 8b of a horizontal louver material 2.
Each of the louver members 1 and 2 is bent outward as shown by the arrows in the figure to form a state 7a in order to prevent the louver members 1 and 2 from coming off.

[Problem that the invention attempts to solve]

In the conventional louver configured as described above, the louver joint structure shown in FIG. 4 is easy to assemble, but the vertical louver material 1 and the horizontal louver material 2 are easily separated, and The problem with the locking structure shown in Figure 1 is that it takes time to assemble.

This invention was made to solve the above-mentioned problems, and aims to provide a louver that is easy to assemble and can securely lock the louver member.

[Means for solving problems]

The louver according to this invention is provided with a locking claw that protrudes outward on the upper part of the horizontal louver member, and a locking part is provided by bending the upper part of the vertical louver member, and the louver is locked when these louver members are joined. The claws are locked to the locking portions.

[Effect]

In this invention, by pushing the horizontal louver member into the vertical louver member, the locking claw easily enters the notch of the vertical louver member while being pressed inward and is locked at the locking part. Moreover, after assembly, the engagement between the locking pawl and the locking portion reliably prevents the louver member from coming off.

〔Example〕

FIG. 1 is a perspective view showing a joint structure of a louver according to an embodiment of this invention, and FIGS. 2 and 3 are perspective views showing a vertical louver member and a horizontal louver member of this louver. In these figures, 9 is a vertical louver member made of a thin plate with a roughly V-shaped cross section;
A notch 10 is formed in the upper half of the horizontal louver member 12, which is approximately equal to the cross-sectional shape of the upper half of the horizontal louver member 12, that is, the shape of the upper half of the V-shape.
The bottom part has a semicircular shape for locking the horizontal louver member 12. Further, the upper ends of the vertical louver members 9 are each bent inward by a predetermined length to form a locking portion 11.

Further, reference numeral 12 denotes a horizontal louver member having approximately the same cross-sectional shape as the vertical louver member 9, and the lower half of the horizontal louver member 12 has the cross-sectional shape of the lower half of the vertical louver member 9, that is, V
A notch 13 is formed that is approximately the same as the shape of the lower half of the letter, and on the upper side of this notch 13 there are a pair of cutouts 13 that are cut and raised so that their tips protrude outside the width of the upper end of the horizontal louver member 12. A locking pawl 14 is provided. Further, the tip of the locking pawl 14 is made substantially the same as the upper surface of the horizontal louver member 12. In addition,
The upper part of the notch 13 has a semicircular shape for locking, similar to the bottom part of the vertical louver member 9.

In order to join the vertical louver member 9 and the horizontal louver member 12 configured in this way, the respective notches 10 and 13 are made to match in the vertical direction, and these louver members 9 and 12 are made to be substantially perpendicular to each other. This is done by pushing in the horizontal louver member 12 from above in the drawing of the vertical louver member 9. At this time, as the horizontal louver member 12 is pushed in, the pair of locking pawls 14 are pressed inward at the open end of the notch 10 of the vertical louver member 9 and contract in width, until the horizontal louver member 12 is completely pushed in. At this position, the louver members 9 and 12 protrude outward due to their elasticity and are engaged with the engagement portions of the vertical louver members 9, as shown in FIG. 1, thereby preventing the louver members 9 and 12 from coming off.

[Effect of idea]

As described above, according to the louver of this invention, the horizontal louver member is provided with a locking pawl that protrudes in the width direction, and the vertical louver member is formed with a locking portion by bending its upper part inward. Since the structure is such that the locking pawl is locked in the portion, the louver member can be securely locked in spite of the relatively simple structure, and the assembly can be easily performed.
