Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention mainly relates to a case body used as the main body of a lighting equipment.

Prior Art The main body of a conventional lighting fixture is shown in FIG. In this figure, a case body 1 is made up of a pair of metal cases 2 and 3, with flanges 2a and 3a joined together.

Problems to be Solved by the Invention In the conventional example described above, there is a problem in which the hands are cut at the edges of the flanges 2a and 3a. In addition, if the cases 2 and 3 are made of iron plates containing a zinc layer, the hardness of the zinc layer tends to cause large burrs, making it even easier to cut the hands. Ta.

The present invention aims to solve the above-mentioned problems and provide a case body that does not cause injury.

Means for Solving the Problems The means of the present invention consists of a pair of metal cases whose flanges are joined together, a folded part is formed at the end of the flanged part of one case, and the inside of this folded part is formed. The flange of the other case is located at the end.

Effect: According to the means of the present invention, by simply forming a folded part on the flange of one case, not only this flange but also the edge of the flange of the other case are protected, thereby eliminating the risk of cutting one's hand. Moreover, the folded part serves as a positioning tool when the pair of cases are joined together, and furthermore, since the folded part does not hold the flange of the other case, the case body can be easily disassembled.

Embodiment An embodiment of the present invention will be described with reference to FIGS. 1 to 6.

The same or corresponding parts as in FIG. 7 are given the same reference numerals. In the present invention, a folded part 3a' is formed at the end of the collar part 3a of one case 3 of a pair of metal cases 2 and 3 in which the collar parts 2a and 3a are joined together, and the inner part of this folded part 3a' is the other case 2 at the end
The collar portion 2a is positioned.

The main parts of FIG. 1 are shown enlarged in FIG. 3.
The folded portion 3a' shown in this figure can be formed most simply, but it may also be curled as shown in FIG. Furthermore, one of the cases 2 may be flat as shown in FIG.

The present invention is effective when coating processing such as painting is not performed after cutting the cases 2 and 3.
(sometimes it occurs at right angles to the end direction of a, and sometimes it occurs at the end direction of the flanges 2a, 3a as in the case of punching and drawing), but only by forming the folded part 3a', Not only the flange 3a but also the edge of the flange 2a are protected, eliminating the risk of cutting one's hand.

Furthermore, the present invention is most effective when the cases 2 and 3 are made of iron plates including a zinc layer. For example, as shown in FIG. In the case of a so-called TM material (trade name, abbreviation of Tough coated Metal) consisting of a treated layer c, a polymeric polyester layer d, and a melamine alkyd layer e, the zinc layer b is harder than the iron plate a.
Although burrs b′ are likely to occur in the process, injuries caused by these burrs can be prevented.

Further advantages of the present invention include the following: In other words, the folded portion 3a' also serves as a positioner when joining the pair of cases 2 and 3.
Easy to assemble. Further, since the folded portion 3a' does not hold the flange portion 2a, the case body 1 can be easily disassembled, which is advantageous when repairing and inspecting the interior.

To explain further in FIGS. 1 and 2,
The case body 1 includes a pair of cases 2 arranged above and below,
Ceiling consisting of 3 parts (cord hanging, chain hanging,
Since the folded part 3a' is formed in the case 3 disposed below, the gap between the collar part 2a and the folded part 3a' cannot be seen from below. It is advantageous in terms of appearance. A switch 4, a glow socket 5, a bulb socket 6, etc. are housed inside the case body 1, and the cases 2 and 3 are usually assembled by connecting the base of the lamp support spring 7 and the flanges 3a, 2a through screws 8. This is done by The chevron portions 2 are formed at the locations where the circumference of the flange portion 2a of the case 2 is divided into three equal parts.
A' is a portion on which a shade (not shown) is placed, and is a small portion compared to the entire flange portion 2a.

Effects of the Invention As is already clear from the above description, the present invention eliminates the risk of injury by (1) the simple addition of forming a folded portion;

(2) The above-mentioned additional means also serves as positioning when joining a pair of cases, making assembly easy.

(3) Since the case body can be easily disassembled, it is advantageous for internal repair and inspection.

This effect is achieved.
