この考案は、主として照明器具に用いるもの
で、屈曲形状の反射板を有する反射装置に関する
ものである。[Detailed Description of the Invention] [Technical Field] This invention is mainly used for lighting equipment, and relates to a reflecting device having a bent-shaped reflecting plate.
従来、屈曲形状の反射板を有する反射装置は、
その反射板が、厚板で製作したものを金型を用
いて所定の湾曲形状に曲げ加工したものか、ある
いは、アルミニウムの押出成形品かであつた。
Conventionally, a reflecting device having a bent-shaped reflecting plate is
The reflector was either made of a thick plate that was bent into a predetermined curved shape using a mold, or it was an extruded aluminum product.
上記の場合、反射板が厚板であることと、そ
の曲げ加工に金型を必要とすること、および曲げ
加工をしなければならないことの相乗によつて、
反射板のコストがかなり高くつくという問題があ
つた。 In the above case, due to the combination of the fact that the reflector is a thick plate, the fact that it requires a mold for bending, and the fact that it has to be bent,
There was a problem that the cost of the reflector was quite high.
さらに、反射板が厚板であるために、取付け状
態におけるスプリングバツクがあり、しかも、そ
のスプリングバツク量が反射板ごとに異なるの
で、厚板製反射板を所定形状に保持するための構
造として、強度の大なるものを必要とするだけで
なく、取付け作業の際にその大なるスプリングバ
ツクのために作業性が低いものとなり、また、こ
れらのこともコストアツプにつながつていた。 Furthermore, since the reflector is a thick plate, there is a spring back when installed, and the amount of spring back differs depending on the reflector, so as a structure for holding the thick reflector in a predetermined shape, Not only is it necessary to have great strength, but also the workability is low due to the large spring back during installation work, and these factors have also led to increased costs.
また、上記の場合には、アルミニウム材料自
体が非常に高価であるうえに、非常に高価な押出
成形機を必要とし、かつ、その押出成形に相当な
コストを必要とするという問題があつた。 Further, in the above case, there was a problem in that the aluminum material itself is very expensive, requires a very expensive extrusion molding machine, and requires considerable cost for extrusion molding.
いずれにせよ、多品種少量生産には全く不向き
であつた。これらに対して、薄板の反射板を湾曲
方向と方向と直角な方向の端部を嵌合させる所定
形状の凹部を有する一対の端板で、反射板の湾曲
形状を保持したものがあつた（たとえば昭和14年
実用新案出願公告第14307号）が、反射板の湾曲
形状を維持しながら反射板を端板で挾むように組
立てるため、組立が面倒であるという欠点があつ
た。 In any case, it was completely unsuitable for high-mix, low-volume production. On the other hand, there was a pair of end plates that retained the curved shape of the reflector by having a recess of a predetermined shape into which the ends of the thin reflector were fitted in the direction perpendicular to the curved direction. For example, Utility Model Application Publication No. 14307 of 1932) had the drawback that assembly was troublesome because the reflector was assembled by sandwiching the reflector between end plates while maintaining the curved shape of the reflector.
この考案の目的は、組立が簡単で反射板の固定
が確実な反射装置を提供することである。
The purpose of this invention is to provide a reflector that is easy to assemble and whose reflector plate is securely fixed.
