Description

[Detailed Description of the Invention] The present invention relates to a joint structure of louvers for lighting equipment, for example, and more specifically, a vertical louver member 1 made of a thin plate with a substantially V-shaped cross section and a horizontal louver member 1 made of a thin plate with a substantially V-shaped cross section. A V-shaped cutout 3 having substantially the same shape as the louver member 2 is formed,
A louver joining structure in which the horizontal louver member 2 is made substantially orthogonal to the vertical louver member 1 and the horizontal louver member 2 is engaged with the cutout 3, and the V of the substantially V-shaped cutout 3 is A locking claw 4 extends in the length direction of the vertical louver member 1 from the cut edge near the upper edge of the shape,
A hook-shaped hook portion 4a is formed on the locking pawl 4, and a substantially V-shaped notch 5 is transparently provided near the upper edge of the horizontal louver member 2. V of 5
A narrow groove-shaped locking recess 5a is formed in the length direction of the horizontal louver member 2 from the notch edge near the upper edge of the letter shape, and the hooking portion 4a of the locking pawl 4 is formed in a narrow groove-like shape. This relates to a joint structure of a louver which is locked in a locking recess 5a to prevent it from slipping out.

An object of the present invention is to provide a louver bonding structure that is easy to bond, increases bonding strength, and does not cause damage during bonding.

Embodiments of the present invention will be described in detail below with reference to the drawings.

In FIG. 1, numeral 6 denotes a vertical louver as the vertical louver member 1, which is formed of a thin plate of synthetic resin or the like and has a substantially V-shaped cross section. A folded piece 7 is formed on the upper edge of the vertical louver 6 over its entire length. The vertical louver 6 is formed with a V-shaped cutout 3 that is substantially the same shape as the horizontal louver member 2 made of a thin plate and has a substantially V-shaped cross section. An arcuate locking piece 8 is formed on the lower edge of the cutout 3. A locking pawl 4 extends in the length direction of the vertical louver member 1 from the cut edge of the substantially V-shaped cut portion 3 near the V-shaped upper edge. The locking claws 4 are provided on each of the side pieces 6a, 6a of the vertical louver member 1. The locking pawl 4 has a hook-shaped hook portion 4a, and a locking groove 9 is formed at the base of the hook portion 4a. In FIG. 1, reference numeral 10 denotes a horizontal louver as the horizontal louver member 2, which is made of a thin plate of synthetic resin or the like and has a substantially V-shaped cross section. A folded piece 11 is formed on the upper edge of the horizontal louver 10 over the entire length. An opening 12 is cut out and formed at the lower end of the horizontal louver 10. An arcuate locking tongue piece 13 is formed on the upper edge of the opening 12 . Also, horizontal louver 1
Approximately V-shaped notches 5 are transparently provided in the V-shaped both side pieces 10a of 0. A locking recess 5a is formed in the length direction of the horizontal louver 10 from an edge of the substantially V-shaped notch 5 near the upper edge of the V-shape. In the embodiment shown in FIG. 1, an arc-shaped guide piece 14 that is convexly curved downward is formed between the locking recesses 5a, 5a.

As shown in FIGS. 3 a, b and 4 a, b, the horizontal louver 1 as the horizontal louver member 2 is attached to the cutout portion 3 of the vertical louver 6 as the vertical louver member 1.
0 is inserted substantially orthogonally. In such a case, as shown in FIGS. 4a and 4b, the locking tongue piece 1 of the horizontal louver 10
3 is a side piece 6a near the opening 12 of the vertical louver 6;
6a, and the locking tongue piece 13 is elastically locked as an elastic piece. Further, the locking piece 8 of the vertical louver 6 enters between the side pieces 10a, 10a of the horizontal louver 10, and the locking piece 8 acts as an elastic piece and is elastically locked. Then, the locking claw 4 of the vertical louver 6 is inserted into the notch 5 of the horizontal louver 10, and the locking claw 4 is inserted into the notch 5 of the horizontal louver 10.
By locking the hook portion 4a in the locking recess 5a, the vertical louver 6 and the horizontal louver 10 are joined with high joint strength. In such a case, the hook portion 4a of the locking pawl 4 is guided by the guide piece 14, and the hook portion 4a of the locking pawl 4 is guided into the locking recess 5
a, and after the engagement, the guide piece 14 prevents the hook portion 4a of the locking pawl from coming out of the locking recess 5a. In addition, in the embodiment, the horizontal louver 1
Although the notch 5 and the opening 12 were formed separately in 0, the notch 5 and opening 12 were formed separately as shown in FIG.
may be formed in series. In such a case, the locking tongue piece 13 is divided into two parts.

In summary, the present invention has a hook-like hook portion formed on the locking pawl, a substantially V-shaped notch transparent near the upper edge of the horizontal louver member, and a substantially V-shaped notch formed in the horizontal louver member. A narrow groove-shaped locking recess is formed in the length direction of the horizontal louver member from the edge of the cutout near the upper edge of the V-shape of the cutout, and the hooking part of the locking pawl is inserted into the narrow groove-shaped locking recess. Since the locking recess is locked to prevent removal, the hook-shaped hook portion formed on the locking pawl is used to join vertical and horizontal louver members made of thin plates with a substantially V-shaped cross section so as to be substantially perpendicular to each other. By having the louver member loosely fit into the approximately V-shaped notch and reach the narrow groove-shaped locking recess, the locking pawl does not scratch the surface of the other louver member by rubbing it, and the Since the retaining pawl is loosely fitted into the V-shaped notch, there is no need to break the retaining pawl or otherwise weakening the joint strength, and the vertical and horizontal louver members can be joined easily and quickly. The hook-shaped hook part is engaged in the narrow groove-shaped locking recess, and the hook-shaped hook part goes around the outer surface side of the horizontal louver member and locks it to prevent it from coming out. The hook-shaped hook portion formed on the horizontal louver member side goes around from the outer surface side of the horizontal louver member to the inner surface side and presses and locks both inner surfaces of the horizontal louver member having a V-shaped cross section. The horizontal louver member with a V-shaped cross section can prevent the V-shaped opening from deforming to the side where it becomes narrower, and conversely, since the locking pawl engages in the narrow groove-shaped locking recess, the locking Approximate cross-section V where the retaining claw is formed
The V-shaped open shape of the vertical louver members can be maintained, and the vertical and horizontal louver members can be easily and quickly joined without causing scratches, while maintaining the V-shaped shape of the vertical and horizontal louver members to each other. There is an advantage that vertical and horizontal louver members having a substantially V-shaped cross section can be joined with high strength.
