Description

[Detailed description of the invention] Industrial field of application This invention relates to a lighting fixture with a cover, in which the lower cover covering the lamp is attached to the main body case attached to the ceiling so that it can be opened and removed. .

Conventional Technology Conventionally, in a lighting fixture in which the lower cover is suspended from the main body case attached to the ceiling and can be pulled down a certain dimension to perform lamp replacement, etc., the main body case and the lower cover are They are connected by a so-called V spring. An example thereof will be explained based on FIGS. 7 to 11. First, the main body case 1 that is attached to the ceiling has
For example, an annular lamp 2 is attached, and a pair of spring fittings 3 are fixed near the edge of the main body case 1 at symmetrical positions with screws or the like (not shown). This spring mounting bracket 3 is formed with a holding tongue piece 4 extending in the horizontal direction, and the coil portion 6 of the V spring 5 is locked to this holding tongue piece 4 so that it cannot be easily removed. There is. This V
The spring 5 has two legs 7 extending from the coil portion 6 and expanding into a V-shape. These legs 7
A rounded tip 8 is formed at the tip.

Further, a lower cover 9 is provided which is joined to the edge of the main body case 1 and covers the lamp 2.
A receiving metal fitting 10 positioned corresponding to the position of the V spring 5 is attached to the lower cover 9 with screws or the like. These receiving fittings 10 have an opening 11 inwardly, and a spring receiving part 12 that communicates with this opening 11 and expands laterally is formed.

In such a configuration, when attaching the bottom cover 9, first, as shown in FIG.
Grasp the legs 7 of the spring 5 with one hand, narrow the gap between the two legs 7, insert the legs 7 through the opening 11 of the receiving metal fitting 10 of the bottom cover 9, and insert your hand through the legs 7. Let go. Thereby, the leg part 7 engages with the spring receiving part 12 by its own spreading force, joins the receiving metal fitting 10 to the tip part 8, and holds the lower cover 9 thereof. Then, as shown in FIG.
When the lower cover 9 is pushed up, the legs 7 of the V spring 5 are expanded as the lower cover 9 is raised, and the expanding force becomes a pulling force for the lower cover 9 to bring the lower cover 9 into close contact with the main body case 1. When removing the bottom cover 9, the reverse operation is performed.

Problems to be Solved by the Invention This conventional method has various problems as follows.

(1) Since the legs 7 of the V-spring 5 must be narrowed, operation is difficult for inexperienced workers.

(2) Since the spring receiving part 12 of the receiving fitting 10 is not visible, the work must be done by groping, resulting in poor workability.

(3) It is necessary to form a circularly rounded tip 8 at the tip of the leg 7 of the V spring 5, which increases the cost.

(4) When removing the bottom cover 9, if you take your hands off the legs 7, it will expand rapidly and hit the main body case, producing a sound, and there is also the risk of damaging the lamp 2.

(5) Since the V spring 5 is unstable during packaging, it is difficult to perform the packaging work.

Means for solving the problem An insertion part into which the coil part is inserted into the lower cover, and an insertion hole in which the leg part is inserted at a position apart from the insertion part and the locking part is locked vertically to prevent it from coming off. A hook-shaped spring mounting bracket is attached to the spring mounting bracket, and the leg portions of the V spring are held at a constant interval by the spring mounting bracket, and the coil portion of the V spring is detachably held when the lower surface cover is attached. A hooking metal fitting having a receiving portion and a restraining plate having a bent portion provided in the opening of the receiving portion were fixed to the main body case.

Function When you pull up the bottom cover by the coil part of the V spring, the leg part of the V spring will naturally narrow, and the locking part of the leg part will lock into the insertion hole to prevent it from coming off. The bottom cover is pulled up without accidentally coming off, and the lower cover is attached to the main body case by locking the pulled-up coil portion of the V spring to a hook on the main body case from below.
Therefore, the hook is easy to see from below, making it easy to work with, and there is no bounce of the V spring when attaching or detaching.Furthermore, the main body case has a hook-shaped receiver that receives the coil part of the V spring, and this receiver Since the opening is equipped with a restraining plate with a bent part, it can be easily attached and detached by pushing the restraining plate with the coil part and moving it laterally, and the operation can be performed with one hand, making it stable. work is done.

Embodiment An embodiment of this invention will be described based on FIGS. 1 to 6. The same parts as those described in FIGS. 7 to 11 above are denoted by the same reference numerals, and the description thereof will be omitted. First, an annular lamp 2, a stabilizer 13, and a glow lamp 14 are attached to the main body case 1, and hooks 15 are fixed to both sides near the edges. This hook 15
is a mounting surface 17 having a mounting hole 16 and this mounting surface 1
Hook-shaped receiving part 1 located a few millimeters lower than 7
8 and more. Moreover, this hooking metal fitting 15 is attached with a restraining plate 19 formed of a spring material interposed therebetween. This restraining plate 19 has a V-shaped bent portion 20. These hook fittings 15 and restraining plate 19 are connected to the main body case 1 by means of screws 21.
is fixed.

Next, a spring mounting bracket 2 is attached to the bottom cover 9.
2 is attached with screws 23. This spring mounting bracket 22 has a cutout-shaped insertion portion 2 in the center of which a coil portion of the V spring, which will be described later, is inserted.
2a is formed, and this insertion portion 22
Two insertion holes 24 at a predetermined interval on both sides of a.
are formed, and these insertion holes 24 have V legs 26 with L-shaped bent portions 25 formed at the tips.
A spring 27 is attached. This V spring 27
is made of highly elastic wire, and a coil portion 28 is formed in the center.

In such a configuration, when attaching the lower cover 9, first grasp the coil portion 28 of the V spring 27 and pull up the coil portion 28. As a result, the leg portion 26 is narrowed by the insertion hole 24, and the bent portion 25 comes into contact with the spring fitting 22.

With the bottom cover 9 thus constructed, the coil portion 28 of the V spring 27 is hooked onto the hook 15 as shown in FIG. At this time, since the part of the hook 15 is visible from below, the operation of hooking the coil part 28 is extremely easy. After the coil part 28 is locked to the hook 15 in this way, the bottom cover 9
push up. As a result, the spring mounting bracket 22 rises with respect to the V spring 27, and the leg portions 26 of the V spring 27 are expanded. In the mounting position, the lower cover 9 is pulled up by the legs 26 and is stable.

Furthermore, when removing the bottom cover 9, first pull down the bottom cover 9. As a result, the leg portion 6 of the V spring 27 is narrowed to the width of the insertion hole 24, and the bent portion 25 comes into contact with the spring mounting bracket 22, so that the lower cover 9 is suspended. Next, V spring 27
grip and remove the coil portion 28 from the hook 15. At this time, since the restraining plate 19 has elasticity, the coil portion 28 can be easily removed by deforming the bent portion 20.

In addition, a V spring 2 attached to the bottom cover 9
7 does not protrude upward when the legs 26 are expanded, so the presence of the V spring 27 does not pose any problem when packaging the bottom cover 9.

Effects of the invention As described above, this invention is such that the main body case and the bottom cover are locked by a V spring, and the insertion part where the coil part is inserted into the bottom cover and the position spaced from this insertion part. Attaching a spring mounting bracket having an insertion hole into which the leg is inserted and the locking part being vertically locked to prevent it from falling out, and holding the legs of the V spring at a constant interval by this spring mounting bracket, At the time of attaching the bottom cover, a hook-shaped receiving part for detachably holding the coil part of the V spring and a holding plate having a bent part in the opening of the receiving part are attached to the main body case. Now that it is fixed, when you pull up the bottom cover by the coil part of the V spring, the legs of the V spring will naturally narrow.
In addition, the locking part of the leg locks into the insertion hole and prevents it from coming off, so it can be pulled up without accidentally coming off, and the coil part of the V spring that has been pulled up can be attached to the hook on the main body case. The bottom cover is attached to the main body case by being locked from below. Therefore, the hook is easy to see from below, making it easy to work with, and there is no bounce of the V spring when attaching or detaching.Furthermore, the main body case has a hook-shaped receiver that receives the coil part of the V spring, and this receiver Because the opening is equipped with a restraining plate with a bent part,
It can be easily attached and detached by pushing the restraining plate with the coil part and moving it laterally, and the operation can be performed with one hand, which has the advantage of allowing stable work.
