Description

[Detailed description of the invention] The present invention relates to a mounting structure for mounting louvers on a reflecting plate having a ■-shaped cross section, and its purpose is to quickly and correctly mount a plurality of louvers in line. There is.

As shown in Fig. 1, a lighting device is provided with a ■-shaped reflector plate 2 made by combining two flat plates in a ■-shape on a fixture body 1, a fluorescent lamp 4 is attached through a socket 3, and a louver 5 is provided on the lower side. Conventionally, a V-shaped reflector 2 is used as shown in FIG.
A slit 6 into which the louver 5 is fitted is provided in the louver 5, and a notch 7 into which the reflector 2 is fitted and a claw 8 protruding toward the inside of the notch 7 are provided in the louver 5. A claw 8 is brought out to the back side of the reflecting plate 2 through a slit 6, and the louver is fixed to the reflecting plate by bending the claw 8.

This type of attachment method requires a lot of work to attach, and even if the shape and dimensions of the slit are made accurately, the louver may end up as shown by the broken line in the figure due to the operator's carelessness when bending the claw 8. There are disadvantages in that a large number of louvers may be installed in a wavy manner due to the inclination, and that if an attempt is made to correct this, the claws 8 may break and correction is not easy.

The present invention aims to improve the above-mentioned drawbacks, and instead of bending the claw 8 to fix the louver to the reflector, a locking member made of an elastic material is used to protrude from the back side of the reflector. The louver is fixed to the reflector by pressing the claw against the upper end of the slit 6.

Hereinafter, the present invention will be explained in more detail with reference to specific examples.

FIG. 3 shows a reflector 2 and a louver 5 in an embodiment of the present invention.
and shows the structure of the locking member 9.

As shown in the front view and cross-sectional view of FIG. 2a, the reflector plate 2 has a plurality of slits 6 extending inward from the V-shaped tip into which the louvers 5 are fitted.

In addition, as shown in Figure b, the louver 5 has an inverted trapezoidal notch 7 shaped along the outer shape of the V-shaped reflector 2 in order to determine the attachment position of the louver 5 to the reflector 2. Furthermore, on both sides of this notch 7, there is a pair of claws 8 that protrude toward the inside of the notch.
is provided.

The locking member 9, as shown in FIG. hole 10,
Holes 12 with raised portions 11 at both ends into which the claws 8 fit
is taking shape.

Now, as shown in Fig. 4a, insert the louver 5 into the slit 6 of the ■-shaped reflector 2, make sure that both sides of the notch 7 of the louver are in the position of the slit 6, and insert the claw 8 through the slit 6 into the reflector. 2, and push the rising parts 11 at both ends of the locking member 9 inward by hand, and insert the louver 5 into the hole 10.
When you insert the claw 8 into the hole 12 in the rising part and release your hand, the locking member 9, which had been bent by hand, expands laterally due to its elasticity, as shown in FIG. A rising force acts on both ends along the ■-shaped inner wall surface of the reflector 2, and this force pushes the claw 8 up along the slit 6.
When the claw 8 hits the upper end of the slit 6, the force of the spring is balanced and the louver is fixed to the reflector.

In this way, the louver claw 8 is always pressed against the upper end of the slit in the reflector by the elasticity of the locking member 9, and this force is symmetrical between the pair of claws 8, so the height of the slit is accurate. If the reflector is made so that all the louvers can be attached to the reflector at the same height without tilting left or right.

FIG. 5 shows another embodiment of the locking member 9.

In this embodiment, both ends of a plurality of elastic wires 13 with a loop 14 formed in the center are attached to both ends of a pair of rods 15 that are slightly shorter than the length of the reflecting plate 2.

When attaching the louvers 5 to the reflector plate 2, as shown in FIG. A pair of rods 1 are placed above 8 as shown by dotted lines in the figure.
5 and push down the rod 15 under the claw 8 to the position shown by the solid line in the figure by hand or with a tool. Due to the elasticity of the elastic wire 13, the two rods 15 expand along the inner slope of the reflector. The louver 5 is fixed to the reflector plate 2 in the same manner as described with reference to FIG. 4 by pushing up the claw 8.

As described above, the present invention provides a plurality of slits 6 at the tip of the ■-shaped reflector 2, a notch 7 that fits on the outside of the reflector 2, and a pair of slits that protrude inwardly on both sides of the notch. A plurality of louvers 5 having claws 8 are fitted into the slits 6, and
The locking member 9 that prevents the elastic material bent in a dogleg shape at an angle greater than the inner angle of the letter-shaped reflector 2 is inserted into the slit 6 of the reflector 2.
Since the louver 5 is fixed between a pair of claws 8 protruding inward from the louver 5 and is mounted so as to push up the pair of claws 8 from below, each louver 5 is always subject to an upward force. is applied, and since this force is symmetrical between the pair of claws 8,
All the louvers are attached to the reflecting plate at the same height without tilting to the left or right, and the notches 7 of the louvers are not exposed to the outside.

Further, no special tools are required to attach the louver, and the attachment operation can be easily and quickly performed.
