【０００１】
【発明の属する技術分野】
本発明は、天板部１２とその両側縁から下向きに折曲する一対の側板部１４を具備する断面コ字形の器具本体１０を備え、前記器具本体１０の下方側に配置される反射板２０を備え、前記器具本体１０に装着される反射板取付け台３０を備え、前記反射板取付け台３０と前記反射板２０との間を回転操作にともなって着脱する回転引掛形のターンファスナ４０を備える蛍光灯器具の反射板固定装置に関するものである。
【０００２】
【従来の技術】
前記構造の蛍光灯器具ないしは反射板固定装置は既知であり、工場あるいは店舗等の照明に現に利用されている。それは図４のようなものである。天板部１２とその両側縁から下向きに折曲する一対の側板部１４を具備する断面コ字形の器具本体１０を備える。器具本体１０の下方側に配置される反射板２０を備える。前記器具本体１０に装着される反射板取付け台３０を備える。前記反射板取付け台３０と前記反射板２０との間を回転操作にともなって着脱する回転引掛形のターンファスナ４０を備える。５０は器具本体１０を固定する天井面である。反射板２０は逆富士形を呈し、その両端は天井面５０に軽く接合する。図外の点灯回路部品は、器具本体１０下面における、反射板取付け台３０を避けた位置に適宜に固定される。図外の蛍光ランプは反射板２０の下面中央に配置される。２灯の場合は反射板２０の各傾斜面の下側に配置される。蛍光ランプのための図外のランプソケットの主要部は、器具本体１０から反射板２０を貫通してその下側に延在する。
【０００３】
【発明が解決しようとする課題】
前記反射板取付け台３０を器具本体１０の下面中央に一対の止めねじ３９を用いて装着するが、その装着に手間がかかる。また、反射板取付け台３０が器具本体１０の下面中央に位置するので、点灯回路部品配置の妨げとなる。さらに、天井面５０・反射板２０間の隙間をターンファスナ４０で吸収することが難しく、密着性が悪い。本発明の目的は、反射板取付け台３０の装着が容易であり、また反射板取付け台３０が点灯回路部品配置の妨げとならず、さらに、天井面５０・反射板２０間の密着性のよい反射板固定装置を提供することである。
【０００４】
【課題を解決するための手段】
本発明は、天板部１２とその両側縁から下向きに折曲する一対の側板部１４を具備する断面コ字形の器具本体１０を備える。前記器具本体１０の下方側に配置される反射板２０を備える。前記器具本体１０に装着される反射板取付け台３０を備える。前記反射板取付け台３０と前記反射板２０との間を回転操作にともなって着脱する回転引掛形のターンファスナ４０を備える。
本発明においては、前記天板部１２における前記各側板部１４寄りの位置に差込み孔１６を形成する。前記各側板部１４における前記差込み孔１６に隣接する位置に係合受け部１８を形成する。
前記反射板取付け台３０は上側が開口するようにＣ字状に曲成された弾力性を有する板材である。前記反射板取付け台３０の両端の脚部３２は前記天板部１２の上面に接する。前記各脚部３２に前記差込み孔１６へ差込まれて係合する切起し部３４を設ける。前記切起し部３４に前記係合受け部１８と弾発的に係合する係合部３６を設ける。
【０００５】
【発明の実施の形態】
図１〜図３を用いて本発明の実施形態について説明する。なお、前記図４の部品符号をなるべくそのまま転用し、重複する説明の一部を適宜に割愛する。本発明に係る蛍光灯器具の反射板固定装置は、天板部１２とその両側縁から下向きに折曲する一対の側板部１４を具備する断面コ字形の器具本体１０を備える。器具本体１０の下方側に配置される反射板２０を備える。前記器具本体１０に装着される反射板取付け台３０を備える。前記反射板取付け台３０と前記反射板２０との間を回転操作にともなって着脱する回転引掛形のターンファスナ４０を備える。天板部１２における各側板部１４寄りの位置に差込み孔１６を形成する。各側板部１４における差込み孔１６に隣接する位置に係合受け部１８を形成する。反射板取付け台３０は上側が開口するようにＣ字状に曲成された弾力性を有する板材である。反射板取付け台３０の両端の脚部３２は天板部１２の上面に接する。各脚部３２に差込み孔１６へ差込まれて係合する切起し部３４を設ける。切起し部３４に係合受け部１８と弾発的に係合する係合部３６を設ける。補足して説明する。側板部１４は器具本体１０を補強する。天板部１２に押出部１９があり、その箇所が天井面５０に当接する。差込み孔１６は角孔である。係合受け部１８も角孔である。反射板取付け台３０は帯状金属材である。反射板取付け台３０は変形六角形状を呈する。係合部３６は切起し形の爪であり、切起し部３４の先端付近に形成される。ターンファスナ４０の頭部は反射板取付け台３０の下部中央に形成された受孔３８と係合する。反射板取付け台３０の装着は切起し部３４を差込み孔１６へ差込んで行う。この際に脚部３２を強めに押すと、係合部３６・係合受け部１８間が弾発的に係合し簡単には抜けなくなる。図１の破線は反射板取付け台３０の原形状であり、それが変形して実線形状の現形状となる。現形状の反射板取付け台３０はターンファスナ４０を引き上げ、反射板２０の各側縁２２を天井面５０に密着させるように働く。反射板取付け台３０のＣ字形の形状はそのための弾力が作用し易い形状である。また、反射板取付け台３０の内腔は器具本体１０の下面に位置するが、そこを占拠しないのでそこに図外の点灯回路部品の一部ないしは全部を配置することが可能となる。
【０００６】
【発明の効果】
本発明は、器具本体の天板部１２に差込み孔１６を形成し、器具本体の各側板部１４に係合受け部１８を形成し、Ｃ字状に曲成された弾力性を有する反射板取付け台３０の両端の脚部３２に切起し部３４および係合部３６を設け、以上の各部を所要のごとくに係合させたものである。これによれば、反射板取付け台３０の装着が容易であり、また反射板取付け台３０が点灯回路部品配置の妨げとならず、天井面５０・反射板２０間の密着性のよい反射板固定装置を提供することができる。

The main part of the lamp socket (not shown) for the fluorescent lamp extends from the fixture body 10 through the reflector 20 to the lower side.
[0003]
[Problems to be solved by the invention]
The reflector plate mount 30 is attached to the center of the lower surface of the instrument main body 10 using a pair of set screws 39, which takes time. In addition, since the reflector mounting base 30 is located at the center of the lower surface of the fixture body 10, the lighting circuit component arrangement is hindered. Furthermore, it is difficult for the turn fastener 40 to absorb the gap between the ceiling surface 50 and the reflecting plate 20, and the adhesion is poor. The object of the present invention is that the reflector mounting base 30 can be easily mounted, the reflector mounting base 30 does not hinder the arrangement of the lighting circuit components, and the adhesion between the ceiling surface 50 and the reflector 20 is good. It is to provide a reflector fixing device.
[0004]
[Means for Solving the Problems]
The present invention includes a U-shaped instrument body 10 having a top plate portion 12 and a pair of side plate portions 14 bent downward from both side edges thereof. A reflector 20 is provided on the lower side of the instrument body 10. A reflector mounting base 30 to be mounted on the instrument body 10 is provided. A rotary hook-type turn fastener 40 is provided that is attached to and detached from the reflector plate mount 30 and the reflector plate 20 in accordance with a rotation operation.
In the present invention, the insertion holes 16 are formed at positions near the side plate portions 14 in the top plate portion 12. An engagement receiving portion 18 is formed at a position adjacent to the insertion hole 16 in each side plate portion 14.
The reflector plate mount 30 is a plate material having elasticity that is bent in a C shape so that the upper side is open. The leg portions 32 at both ends of the reflector mounting base 30 are in contact with the upper surface of the top plate portion 12. Each leg portion 32 is provided with a cut-and-raised portion 34 that is inserted into and engaged with the insertion hole 16. The cut-and-raised portion 34 is provided with an engagement portion 36 that elastically engages with the engagement receiving portion 18.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
The embodiment of the present invention will be described with reference to FIGS. Note that the component codes in FIG. 4 are used as they are, and a part of the overlapping description is omitted as appropriate. The reflector fixing device for a fluorescent lamp fixture according to the present invention includes a U-shaped fixture body 10 having a top plate portion 12 and a pair of side plate portions 14 bent downward from both side edges thereof. A reflector 20 is provided on the lower side of the instrument body 10. A reflector mounting base 30 to be mounted on the instrument body 10 is provided. A rotary hook-type turn fastener 40 is provided that is attached to and detached from the reflector plate mount 30 and the reflector plate 20 in accordance with a rotation operation. Insertion holes 16 are formed at positions near the side plate portions 14 in the top plate portion 12. An engagement receiving portion 18 is formed at a position adjacent to the insertion hole 16 in each side plate portion 14. The reflector plate mounting base 30 is a plate material having elasticity that is bent in a C shape so that the upper side opens. The leg portions 32 at both ends of the reflector mounting base 30 are in contact with the upper surface of the top plate portion 12. Each leg portion 32 is provided with a cut-and-raised portion 34 that is inserted into and engaged with the insertion hole 16. An engaging portion 36 that elastically engages with the engagement receiving portion 18 is provided in the cut and raised portion 34. A supplementary explanation will be given. The side plate portion 14 reinforces the instrument body 10. The top plate portion 12 has an extruding portion 19, and the portion abuts against the ceiling surface 50. The insertion hole 16 is a square hole. The engagement receiving part 18 is also a square hole. The reflector mounting base 30 is a strip-shaped metal material. The reflector mounting base 30 has a deformed hexagonal shape. The engaging portion 36 is a cut-and-raised claw and is formed near the tip of the cut-and-raised portion 34. The head of the turn fastener 40 engages with a receiving hole 38 formed at the lower center of the reflector plate mount 30. Mounting of the reflector mounting base 30 is performed by inserting the cut and raised portion 34 into the insertion hole 16. At this time, if the leg portion 32 is pressed strongly, the engagement portion 36 and the engagement receiving portion 18 are elastically engaged and cannot be easily removed. The broken line in FIG. 1 is the original shape of the reflector mounting base 30, which is deformed into a solid line shape. The reflector plate mount 30 in the current shape works to pull up the turn fastener 40 and bring the side edges 22 of the reflector plate 20 into close contact with the ceiling surface 50. The C-shaped shape of the reflector mounting base 30 is a shape on which the elasticity for that is easily applied. Moreover, although the lumen | bore of the reflector mounting base 30 is located in the lower surface of the instrument main body 10, since it does not occupy there, it becomes possible to arrange | position some or all of the lighting circuit components outside a figure there.
[0006]
【The invention's effect】
In the present invention, an insertion hole 16 is formed in the top plate portion 12 of the instrument main body, an engagement receiving portion 18 is formed in each side plate portion 14 of the instrument main body, and the reflector is bent in a C shape. A cut-and-raised part 34 and an engaging part 36 are provided on the leg parts 32 at both ends of the mounting base 30 and the above-described parts are engaged as required. According to this, it is easy to mount the reflecting plate mounting base 30 , and the reflecting plate mounting base 30 does not hinder the arrangement of the lighting circuit components, and the reflecting plate is fixed with good adhesion between the ceiling surface 50 and the reflecting plate 20. An apparatus can be provided.
