Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a reflective shade attachment device for a lighting device, and more particularly to a structure for attaching a reflective shade to a main body.

[Background of the engineer behind the idea and problems with the product]

The conventional mounting device for attaching the reflective shade of this type of lighting equipment to the main body of the lighting equipment is as shown in FIG. 4 of the fixture 3 is inserted in an inclined manner, and the hook part 4 of the fixture 3 is inserted into the locking hole 6 formed in the instrument body 5. In this state, the fixture 3 is rotated to lock the hook part 4 into the fixture body. 5 is known, but this structure has the disadvantage that the fixture 3 easily comes off from the reflective shade 1.

For this reason, as shown in Japanese Utility Model Application Publication No. 50-90962, a structure has been devised that prevents the fixture from coming off from the reflective shade.

In this structure, as shown in FIG. 7, protrusions 7 are formed in the upper surface at both ends of the insertion hole 2 of the reflective shade 1, and the protrusions 7
The hook portion 4 of the fixture 3 inserted into the insertion hole 2 is engaged with the hook portion 4 to prevent the hook portion 4 from being removed from the insertion hole 2.

However, with this structure, when the reflective shade 1 is stacked and stored in a painted state in the painting process during the manufacturing process of the reflective shade 1, the protrusion 7 comes into contact with and slides on the reflective surface of the reflective shade 1. Care must be taken when stacking the reflective shade 1 to avoid scratches, resulting in poor workability, and the stacked reflective shade 1 must be handled with care during the assembly work of the reflective shade 1. The work efficiency is poor, and furthermore, when a plurality of reflective shades 1 are stacked and packaged, there is a risk that scratch marks may be generated on the reflective surface due to sliding during transportation, which causes problems.

On the other hand, grooves 8 as shown in FIG. 8 are formed in communication with both ends of the insertion hole 2 of the reflective shade 1, so that the diameter of the insertion hole 2 is made small so that the hook part 4 of the fixture 3 is difficult to remove. Such a structure is known, but such a reflective shade is suspended by engaging a hook in the insertion hole 2 during the painting process, but the groove 8 is easily deformed by shaking during the cleaning process. Furthermore, if the cut groove 8 is not formed, the diameter of the insertion hole through which the hook of the fixture is inserted must be increased, as shown in FIG. 9, and this has the disadvantage that the hook is easily removed. .

[Purpose of invention]

The present invention was created in view of the above points, and does not require increasing the diameter of the insertion hole through which the hook of the reflective shade mount is inserted.
The hook part is difficult to remove from the insertion hole, the insertion hole is not deformed even if it is hung with a hook during the painting process, and a protrusion is formed at the end of the insertion hole of the reflective shade. To provide a mounting device for a reflective shade of a lighting fixture, which prevents scratches from being caused on the reflective surface of the reflective shade when stacked in a flat shape, and further allows easy insertion of a hook part of a fixture into an insertion hole.

[Summary of the idea]

The structure of the present invention is that the insertion hole through which the hook of the fixture formed on the reflective shade is inserted is formed by a circular hole and a slot continuous to the inner end of the circular hole facing the center of the reflective shade. The length from the end of the circular hole facing outside of the reflective shade to the end of the slot is shorter than the length of the hook part of the fixture, so that the hook part can be inserted at an angle. be.

□ [Embodiment of the invention] Next, the structure of an embodiment of the invention will be explained with reference to FIGS. 1 to 5.

Reference numeral 10 denotes a lighting equipment main body, which is formed into a substantially U-shaped cross section, in which lighting devices such as a ballast and lighting tube are housed and fixed, and lamp socket mounting plates 11 are provided opposite to each other at both ends of the lower surface.
A reflective shade mounting plate 12 is provided inside each of the socket mounting plates 11 and facing the opening of the main body 10.

This reflective shade mounting plate 12 has a hook portion 1 of a mounting tool 13, which will be described later.
A locking hole 15 is formed in the shape of a long groove into which a locking hole 4 can be inserted.

In addition, 16 is a reflective shade, the lower surface is a reflective surface, and this reflective shade 1
Insertion holes 17 are formed at both ends of the body 6 in correspondence with the positions of the locking holes 15 of the main body 10.

This insertion hole 17 consists of a circular hole portion 18 and a slot portion 19 that is continuous with the inner end of the circular hole portion 18 toward the center of the reflective shade 16. It has a width a into which the portion 14 can be inserted.

The length from the end of the circular hole 18 facing outside of the reflective shade 16 to the slot 19 is shorter than the length b of the hook 14 of the fixture 13 and is long enough to allow the hook 14 to be inserted at an angle. C
is formed.

Next, the fixture 13 includes a base portion 20 having a diameter larger than the insertion hole 17 of the reflective shade 16, and a support rod portion 21 integrally formed to protrude from the upper surface of the base portion 20. A hook portion 14 is integrally formed at the upper end of the support rod portion 21 in a manner perpendicular to the support rod portion 21 .

Further, a supporting rod portion 21 is provided on the upper surface of the base portion 20 of the fixture 13.
Rotation guide protrusions 22 are protruded from both sides of the base portion 20, and a knob portion 23 is integrally formed on the lower surface of the base portion 20.

Next, the operation of this embodiment will be explained.

When attaching the reflective shade 16 to the main body 10, as shown in FIG. 3 and FIG. The fitting 13 is inserted into the circular hole 18 , and with one end of the hook 14 inserted through the insertion hole 17 , the fixture 13 is raised horizontally, and the other end of the hook 14 is inserted through the slot 19 .

In this state, as shown in FIG. 4, the length C from the outer end of the insertion hole 17 to the end of the slot 19 is equal to the length b
Since it is shorter, the hook portion 14 will not be easily removed from the insertion hole 17.

. Next, when the fixture 13 is inserted into the locking hole 15 of the reflective shade mounting plate 12 of the main body 10 and rotated approximately 90 degrees by holding the knob 23, the fixture 13 engages with the circular hole 18 of the insertion hole 17 and the rotation guide protrusion. 22, and the hook portion 14 of the fixture 13 is locked perpendicularly to the locking hole 15.

In this state, the reflective shade 16 is fixed to the main body 10 with the fixture 13.

In addition, when removing the reflective shade 16 from the main body 10, use the mounting tool 1.
3 by approximately 90 degrees, the hook portion 14 matches the direction of the locking hole 15, and the waist hook portion 14 can be removed from the locking hole 15.

Note that when the reflector shade 16 is attached to the main body 10, a lamp socket 25 attached to the socket mounting plate 11 of the main body 10 protrudes from the notches 24 formed at both ends of the reflector shade 16, and a straight tube type fluorescent lamp is attached to the socket 25. Attach the lamp.

Further, as shown in FIG. 6, even if the hook 26 is stopped and hung in the through hole 17 of the reflective shade 16 in the painting process of the manufacturing process of the reflective shade 16, the groove portion 19 of the through hole 17 is not attached to the reflective shade 1.
6, the slot 19 is in a downward position, and the slot 19 is not deformed by the hook 26.

Further, even if the reflective shade 16 is stacked, since the reflective shade 16 has no protrusions and is formed in a flat shape, no scratches will be formed by the protrusions.

In addition, in the description of the above embodiment, one end of the hook part 14 of the fixture 13 is first inserted through the circular hole 18 of the insertion hole 17 of the reflective shade 16, but it is also possible to insert the hook part 14 first through the slotted hole part 19. Next, the other end of the hook 14 may be inserted into the circular hole 18.

Further, in the embodiment, the socket mounting plate 11 and the reflective shade mounting plate 12 of the main body 10 are formed separately, but they may be formed integrally.

[Effect of idea]

According to the present invention, the insertion hole of the reflective shade consists of a circular hole and a slot continuous to the inner end of the circular hole facing the center of the reflective shade, and the end of the circular hole facing the outside of the reflective shade. The length from the end of the slot to the end of the slot is shorter than the length of the hook of the fixture that attaches this reflective shade to the main body, so that the hook can be inserted at an angle, so the diameter of the circular hole of the insertion hole The hook part of the fixture inserted into the insertion hole of the reflective shade can be made small, and the hook part of the fixture inserted into the insertion hole of the reflective shade will not come off, making it easy to install the reflective shade. There is no need for protrusions to prevent mating rotation, the processability of the reflective shade is good, and even when the reflective shade is stacked during manufacturing, assembly, or packaging, the reflective shade has no protrusions and is flat. Because of the shape, there are no scratch marks, which improves work efficiency.

Furthermore, since the insertion hole of the reflective shade is formed from a circular hole to a groove toward the center of the reflective shade, even if a hook is used to hang it from the insertion hole during the painting process, the downward groove will not be deformed by the hook. There is no risk of this happening.
