Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a lighting device with a translucent cover,
In particular, the present invention relates to a lighting device with a light-transmitting cover that is hung by pulling a light-transmitting cover that covers the lamp arranged in the lighting device body with a spring.

[Conventional technology]

Conventionally, in a lighting fixture with a light-transmitting cover such as a ceiling light, as a mechanism for attaching a light-transmitting cover for light distribution control that covers the lamp to a lighting fixture body in which the lamp is arranged,
A luminaire adopting the one shown in FIG. 6 and FIG. 6 is well known.

In this lighting fixture, a cover mounting spring 7 is swingably attached to the lower surface of the lighting fixture body 1 in the shape of a substantially rectangular dish in the vicinity of two opposite sides, and a transparent light is formed in a substantially rectangular box shape with an acrylic resin sheet or the like. The cover mounting spring 7 is engaged with the spring receiver 6 mounted on the opening peripheral edge of the cover 5, and the translucent cover 5 is pulled by the spring force of the cover mounting spring 7 to the luminaire main body 1 and suspended.

The cover mounting spring 7 includes a coil portion 71 formed by bending a wire rod.
And two leg portions 72 extending from the coil portion 71. In the free state, the two leg portions 72 expand into a substantially V shape. The cover mounting spring 7 is attached to the lighting device main body 1 so as to be capable of swinging by inserting the fitting 8 into the coil portion 71 and preventing it from slipping out, and the leg portion 72 is projected toward the opening side of the lighting device main body 1.

The spring receiver 6 is formed in a slit shape wider than the diameter of the coil portion 71 of the cover mounting spring 7 and narrower than the space between the two leg portions 72 in the free state, and clamps the leg portion 72 by sandwiching it. It has a part 63.

When attaching the translucent cover 5 to the lighting device main body 1, first, the leg portion 72 of the cover mounting spring 7 is bent and inserted into the holding portion 63 of the spring receiver 6, and the cover mounting spring 7 is attached to the holding portion 63. It locks in the vicinity of the tips of the two legs 72. At this time, the two leg portions 72 of the cover mounting spring 72 try to expand, but the leg portions 72 and the pinching portion 6 are locked because they are locked near the tip.
The frictional force between the light transmissive cover 3 and the leg portion 72 is larger than the force for sliding the leg portion 72, and the translucent cover 5 maintains a state of being hung apart from the luminaire main body 1.

Then, when the translucent cover 5 is pushed up to the side of the luminaire main body 1, as the leg portion 72 of the cover mounting spring 7 is made up of the coil portion 71 with respect to the pinching portion 63 of the spring receiving member 6, the spring receiving member 6 and the leg portion are separated from each other. The contact angle between the leg 72 and the leg 72 becomes shallower.
The frictional force between the gripping portion 6 and the pinching portion 6 becomes smaller than the force for sliding the leg portion 72, and the translucent cover 5 is closer to the luminaire main body 1 due to the spring force due to the expansion of the two leg portions 72. Then, the translucent cover 5 and the luminaire main body 1 are held in close contact with each other.

However, in this luminaire with a translucent cover, it is necessary to bend the cover mounting spring 7 and insert it into the spring receiver 6 every time the translucent cover 5 is mounted on the luminaire main body 1. When 7 is attached, the spring receiving tool 6 that engages with the other cover attaching spring 7 cannot be seen, so the workability is poor. If the cover attaching spring 7 cannot be inserted into the spring receiving instrument 6, the cover attaching spring 7 pops up. There is a risk of hitting the transparent cover 5 and damaging the transparent cover 5, and there is a problem that it is difficult to know whether the cover mounting spring 7 is securely locked to the spring receiver 6.

Therefore, in order to solve the above problems, Japanese Patent Publication No.
Illumination equipment with a light-transmitting cover, which is described in Japanese Patent Laid-Open No. 0083 and Japanese Utility Model Publication No. 61-153926, has been proposed.

In Japanese Patent Publication No. 61-20083, as shown in FIGS. 7 and 8, a spring receiver 6 provided with a retaining portion 64 for retaining and supporting the coil portion 71 of the cover mounting spring 7 is provided as a translucent cover. A cover mounting spring 7 is attached to the spring receiving member 6 so as to be retractable. Then, the cover mounting spring 7 is pulled out, the tip of the leg portion 72 is locked to the spring receiver 6, and the coil portion 71 of the cover mounting spring 7 is pulled out.
Is projected from the light-transmitting cover 5, and the coil portion 71 of the cover mounting spring 7 is engaged with the hooking piece 83 formed on the vertical piece 82 of the fixture 8 provided in the luminaire main body 1 to fix the light-transmitting cover 5 to the luminaire. The translucent cover 5 is held in close contact with the luminaire main body 1 by the spring force that pushes it up toward the main body 1 and the leg portion 72 of the cover mounting spring 7 expands. In order to prevent the coil portion 71 of the cover mounting spring 7 from being disengaged from the engaged hook 83 of the fitting 8, the horizontal piece 81 of the fitting 8 has a tip located near the tip of the hook 83. A stopper 84 is provided.

Further, in Japanese Utility Model Laid-Open No. 61-153926, as shown in FIGS. 9 and 10, it is substantially the same as that described in Japanese Patent Publication No. 61-20083, but the pinching portion 63 of the spring receiver 6 is used. Also, the retaining portion 64 is provided by forming a pair of circular holes in the horizontal piece 62, and the retaining tool 9 formed of a spring material as a separate component from the mounting tool 8 has its tip hooked on the mounting tool 8. It is arranged in the lighting fixture main body 1 so as to project from the tip of 83.

[Problems to be solved by the device]

However, in any of the above-mentioned conventional examples, it is hard to feel whether or not the coil portion 71 of the cover mounting spring 7 is securely engaged with the hooking piece 83 of the mounting member 8, and in particular, it is not disclosed in Japanese Utility Model Laid-Open No. 61-153926. In the case of the one described in the publication, there is a possibility that the coil portion 71 of the cover mounting spring 7 may be locked to the retaining member 9, and in any case, the mounting of the translucent cover 5 to the lighting fixture body 1 is surely completed. There was a problem that it was difficult to understand what was done.

The present invention has been made in view of the above background, and provides a light fixture with a translucent cover in which it is found that the coil portion 71 of the cover mounting spring 7 is securely engaged with the fixture 8, and a mounting error is less likely to occur. Is what you are trying to do.

[Means for Solving the Problems]

The luminaire with a translucent cover according to the present invention has a luminaire main body having a lamp opened at a lower surface, a translucent cover attached to the luminaire main body to cover the lamp, a coil portion, and extending from the coil portion. Two cover mounting springs, which consist of two legs and have two legs that spread out in a substantially V-shape in a free state, and a cover mounting spring that is attached to one of the main body of the lighting fixture or the translucent cover. A plurality of cover mounting springs are attached to the cover mounting spring so as to be retractable. A plurality of attachments having a spring receiver and a hooking piece that is attached to the other of the main body of the luminaire or the light-transmitting cover in correspondence with the spring receiver and that hooks the coil portion of the cover attachment spring in a disengageable and swingable manner. Stuff and ba Made of a material, the tip of which is inward of the hooking piece of the fixture, and which is provided in the lighting fixture body with a gap approximately the same as the width of the coil portion between the hooking piece and the hooking piece. is there.

[Action]

According to the present invention, the retainer, which is made of a spring material and has a tip located inward of the tip of the hook of the fixture and having a gap approximately the same as the width of the coil between the hook and the hook, is arranged in the main body of the illuminator. Therefore, when engaging the cover mounting spring with the mounting tool, a sound is generated when the retainer is pushed back by the coil portion, and it can be confirmed that the cover mounting spring has engaged with the mounting tool. It can be attached.

〔Example〕

The illuminator with a translucent cover of this embodiment is a ceiling light using a plurality of round fluorescent lamps as lamps.

The luminaire main body 1 having a substantially tray-like shape is equipped with a fluorescent lamp socket 2 integrally formed with a lamp holder on the lower surface thereof and a lamp support spring 3, and two round fluorescent lamps 4 having different diameters are mounted as lamps. The lighting device is connected to the power supply and can be lit by a lighting device (not shown).

The translucent cover 5 is formed by forming a milky white acrylic resin sheet into a substantially thin pot shape. The translucent cover 5 is attached to the spring receivers 6 at both ends of one diameter of the opening periphery, and is locked to the spring receivers 6. The cover mounting spring 7 is provided.

As shown in FIG. 3, the spring receiver 6 is formed by bending a thin steel plate into a substantially L-shaped cross section, and is attached to the translucent cover 5 by a vertical piece 61. The horizontal piece 62 has a pair of substantially L-shaped parts. A sandwiching portion 63 which is formed in a slit shape and which sandwiches the cover mounting spring 7 is formed. A retaining portion 64 for retaining and supporting the cover mounting spring 7 is provided between the pair of clamping portions 63.

As shown in FIG. 3, the cover mounting spring 7 has a coil portion 71 formed by bending a wire and the coil portion 7 as in the conventional example.
It is composed of two leg portions 72 extending from 1, and in the free state, the two leg portions 72 are expanded into a substantially V shape. The tip of the leg portion 72 of the cover mounting spring 7 is bent to form an engaging portion 73 that comes into contact with the spring receiver 6. The engaging portion 73 is formed by bending the leg portion 72 outward at an obtuse angle and bending the tip end thereof in a ring shape farther from the coil portion 71. Further, the vicinity of the engaging portion 73 of the leg portion 72 is slightly bent inward so that slippage is unlikely to occur when the leg portion 72 is inserted into the spring receiver 6.

At a position corresponding to the cover mounting spring 7 mounted on the translucent cover 5 on the lower surface of the luminaire main body 1, a mounting tool 8 for hooking the coil portion 71 of the cover mounting spring 7 is mounted by a screw. As shown in FIGS. 1 and 4, the attachment 8 is made by bending a thin steel plate into an L-shaped cross section, and
1 is attached to the main body 1 of the luminaire, and the coil portion 71 of the cover mounting spring 7 is hooked to the hooking piece 83 which is cut and raised by connecting the central portion in the vicinity of the lower end of the vertical piece 82 and protruding obliquely outward. It is the one.

In addition, a retaining member 9 formed of a spring material is attached to the luminaire main body 1 together with the fixture 8 by a screw for fixing the fixture 8. The retainer 9 is bent downward so that its tip approaches the vicinity of the tip of the hooking piece 83 of the fixture 8, and a cover is provided between the tip of the retainer 9 and the hooking piece 83 of the fixture 8. The spacing is set to be substantially the same as the width of the coil portion 71 of the mounting spring 7.

Is pulled up, the cover mounting spring 7 is made to stand up from the spring receiver 6, and the coil portion 71 of the cover mounting spring 7 is projected upward. At this time, the two leg portions 72 of the cover mounting spring 7 try to expand, but the frictional force between the leg portion 72 and the pinching portion 63 is generated because the leg portions 72 are locked near the tip.
Is larger than the force for sliding the cover mounting spring 5, and the cover mounting spring 5 maintains the protruding state.

Next, when the coil portion 71 of the cover mounting spring 7 is hooked on the hooking piece 83 of the mounting member 8, the translucent cover 5 is kept separated from the lighting fixture body 1 and maintained in a suspended state. At this time, the coil portion 71 comes into contact with the upper surface of the retainer 9 and pushes the retainer 9 downward, and finally the coil portion 71 is positioned below the retainer 9 and the hooking piece 83 of the attachment 8 is attached.
However, when the retaining member 9 is disengaged from the coil portion 71, the retaining device 9 makes a snapping sound due to its spring property and returns to its original position.

Then, when the translucent cover 5 is pushed up to the side of the luminaire main body 1, as the leg portion 72 of the cover mounting spring 7 comes into contact with the pinching portion 63 of the spring receiver 6 from the coil portion 71, The contact angle between the spring receiver 6 and the leg portion 72 becomes shallow, and the frictional force between the leg portion 72 and the pinching portion 63 causes the leg portion 7 to move.
It becomes less than the force to slide 2 and the two legs 7
The translucent cover 5 is pushed up toward the luminaire main body 1 by the spring force due to the expansion of 2, and the translucent cover 5 and the luminaire main body 1 are held in close contact with each other.

The shape of the pair of retaining portions 63, 63 of the spring receiver 6 and the retaining portion 64 between these retaining portions 63, 63 is different from that of the above-described embodiment, but the pair of retaining portions 63 is different. , 63 may be formed as an oval hole, a circular hole, a square hole, or the like, instead of the notch shape, and the retaining portion 64 may be provided between them. Further, the cover mounting spring 7 has the leg portion 72 and the spring receiver 6 as in the above-described embodiment.
Coil part 71
Instead of being hooked on the fixture 8, it may be attached as in the conventional example shown in FIGS. 6 and 7,
The cover mounting spring 7 may be mounted on the luminaire main body 1 or the translucent cover 5. Furthermore, although the above-mentioned embodiment is a ceiling light and is a direct type lighting fixture, it may be an embedded lighting fixture.

[Effect of device]
