Description

[Detailed description of the invention] [Technical field] The present invention is a type of device that has end covers on both sides of the main body of indicator lights, guide lights, etc., and that displays, lamps, etc. can be replaced by attaching and detaching the end covers. It relates to lighting equipment.

[Background technology]

FIG. 5 shows a perspective view of a conventional lighting device main body 1', in which end shears 4' are installed vertically at both ends of an upper plate 3a and a lower plate 3b, respectively.
Further, a panel or display board 14 is slidably inserted into the front surface by bridging the ends of the upper plate 3a and the lower plate 3b. When the display plate 14 is inserted into the main body 1', the end covers 2' are fitted from both sides.
In such conventional examples, there have been various methods of locking the end cover 2' with dowels or recesses, but when the end cover 2' is locked, a gap may be created between the end cover 2' and the main body 1', or the end cover 2' may be locked with the main body 1'. There were problems such as deformation. Also, when attaching and detaching the end cover, insert a coin 11 or the like into the slit 15 and remove the end cover 2' as shown in Fig. 6, so that the end cover 2' is twisted and cracks or deformations occur in the fitting parts. I was used to it.

[Purpose of invention]

The present invention has been proposed in view of the above-mentioned points, and it is easy to attach and detach the fitting part, etc., and even when removing the end cover with a coin etc., it does not dig into the main body and is easy to remove, and the main body and the end cover are easy to remove. The object of the present invention is to provide a lighting fixture in which a gap is unlikely to be formed between the abutting surfaces.

[Disclosure of invention]

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 shows a perspective view of a main part, and a substantially U-shaped end sheath 4 is disposed at both ends of an upper plate 3a and a lower plate 3b of the main body 1. The upper piece 5 of the end sheath 4 has a stepped portion bent to provide a space 7 between it and the upper plate 3a, and its tip is fixed to the upper plate 3a of the main body 1 with a fixture 17. Further, in the upper piece 5 of the end sheath 4 facing the space 7, a recess 8 having a substantially semicircular cross section is formed so as to be recessed inward. Although only the upper side is shown in the figure, the lower side is similarly formed symmetrically. The end cover 2 that covers the sides of the main body 1 or the end sheath 4 is formed in a substantially U-shape, and its upper and lower ends are formed symmetrically as follows. That is, an elastic insertion piece 9 that extends from the end surface of the end cover 2 to the upper surface is integrally formed on the main body 1, and a pair of guide pieces 16 are formed on both sides.
Furthermore, an end shear seam 4 is provided on the lower surface of the insertion piece 9.
A rib 10 that fits into the recess 8 is integrally formed. The distance l between the recess 8 on the side of the main body 1 and the end of the upper plate 3a is equal to the distance l between the end face of the end cover 2 and the rib 10 of the insertion piece 9, and this distance l
is set as small as possible. Also, rib 1
The lower surface of the insertion piece 9 near the tip end is formed with a tapered surface 13 having an inclination of θ, and when the end cover 2 is removed with a coin 11 or the like, the end cover 2 is removed by θ as described later. Because it rotates,
This is provided to prevent the lower surface of the insertion piece 9 from coming into contact with the upper piece 5 of the end shear sheath 4. Further, since the end cover 2 is configured to rotate, the thickness of the insertion piece 9 is made smaller than the thickness of the space 7. Furthermore, a groove 12 for inserting a coin 11 is cut into the end surface of the end cover 2 and communicates with the upper surface of the insertion piece 9.

In the attached state, that is, in the fitted state between the rib 10 and the recess 8, as shown in FIG. At the same time, the end cover 2 is lifted up by the reaction force, and the end surface of the end cover 2 presses against the end surface of the main body 1, creating an adhesion force that prevents the end surface of the main body 1 from being exposed. 1 and end cover 2
There will be no gap between them. Therefore,
Light from inside the main body 1 does not leak to the outside. Moreover, since there is no gap between both end faces, the appearance is also good.

Next, when removing the end cover 2 with the coin 11, proceed as follows. That is, the coin 11 is inserted into the groove 12 at the lower end of the end cover 2 and twisted to spread the end cover 2 outward, and the lower rib 10 and the recess 8 are disengaged from each other. Further, as shown in FIG. 4, the upper end surface of the end cover 2 and the end surface of the main body 1 are pressed together, and this end surface of the end cover 2 rotates as the rotation axis of the end cover 2. At this time, force is applied to the end face of the end cover 2, which serves as the rotating shaft, and no stress is applied to the rib 10, so that the rib 10 is not damaged or deformed, and quality is maintained. Then, the outward rotation angle θ of this end cover 2
As the rib 10 is rotated, the rib 10 is pulled out from the recess 8, and the tapered surface 13 on the lower surface of the insertion piece 9 near the tip of the rib 10 moves along the surface of the end shear sheath 4 as shown by the arrow in the figure. In this way, the rib 10 naturally comes off from the recess 8, making it easy to remove. Furthermore, since the groove 12 into which the coin 11 is inserted is provided on the back surface of the rib 10, there is no light leakage from the groove 12, and a pulling force acts directly on the rib 10, making removal easy.

Finally, when attaching the end cover 2 to the main body 1, the guide piece 16 of the end cover 2 is inserted between the main body 1 and the end sheath 4 to guide the end cover 2. The tapered surface 13 of the insertion piece 9 of the end cover 2 is guided along the surface of the end sheath 4, the rib 10 and the recess 8 are fitted, and the end cover 2 is attached to the main body 1. At this time, since the corners of the end sheath 4 are curved, the end cover 2 can be inserted smoothly.

[Effect of idea]

As described above, the present invention provides a lighting equipment in which an end cover that covers the side part of the lighting equipment body is removably fitted to the side part of the lighting equipment body. A U-shaped end shear is constructed, and the upper and lower pieces of the end shear are fixed to the upper and lower plates of the lighting equipment body with a space provided,
An inward fitting recess is formed in the upper and lower pieces of the end shear, and an elastic insertion piece extending from both end faces of the end cover and inserted into the space is fitted into the recess. Protruding ribs are provided to match the
When the rib and the recess are fitted together, the elasticity of the rib presses the insertion piece against the recess, and the insertion piece lifts up from the outer surface of the end shear. A groove for inserting a coin is provided on the end face of the end cover on the back side of the rib, and the groove for inserting a coin is removed by twisting a coin or the like and applying force outward of the end cover.
One end of the end cover is opened outwardly and the other end of the end cover is opened on one side of the insertion piece that is in contact with the surfaces of the upper and lower pieces of the end shear seam and has a thickness smaller than the thickness of the above-mentioned space, in order to remove the rib from the recess. Since the tapered surface is formed to rotate the end cover using the end face as the rotation axis, when removing the end cover with a coin etc., the tapered surface part of the insertion piece becomes a relief when the end cover is rotated. With,
The part where the end face of the end cover and the end face of the main body press together becomes the rotation axis, and force is applied to this rotation axis, and no stress is applied to the ribs, so there is no damage or deformation of the ribs.
In addition to maintaining quality, the end cover can be easily removed because the ribs naturally come out of the recesses. In addition, when the end cover is attached to the main body, the end surfaces of the main body and the end cover are in contact and there is no gap between the two, so there is no light leakage from inside the main body, and it has the advantage of being aesthetically pleasing. Since the groove into which the coin is inserted is provided on the back surface of the rib, there is no light leakage from this groove, and the coin has the advantage that a pulling force acts directly on the rib, making it easy to remove.
