Description

本発明は、照明器具に係り、特に照明器具の取り付け構造に関するものである。   The present invention relates to a lighting fixture, and more particularly to a mounting structure for a lighting fixture.

一般にダウンライトなどの照明器具は、天井板に埋め込み穴を設け、天井に埋め込むことによって取り付けられている。通常、埋め込み穴にばねを用いて取り付けられるが、比較的重量のある照明器具を支える必要があるため、機械的強度の高いものが必要となる。
例えば、取り付けばねを埋め込み型機器の取り付け装置の本体に取り付けて本体側に折り曲げ、天井などに設けた埋め込み穴に挿入した後、取り付けばねの復元力によって埋め込み穴に本体を取り付けるに際し、本体の側壁に対向して平面部を有するばね取り付け部を設け、ばね取り付け部の平面部に取り付けばねを取り付けるようにしたものが提案されている(特許文献１)。 In general, a lighting device such as a downlight is attached by providing an embedding hole in a ceiling plate and embedding it in the ceiling. Usually, it is attached to the embedding hole using a spring. However, since it is necessary to support a relatively heavy luminaire, a high mechanical strength is required.
For example, after attaching the mounting spring to the main body of the mounting device of the implantable device, bending it to the main body side, inserting it into the embedding hole provided in the ceiling, etc., when attaching the main body to the embedding hole by the restoring force of the mounting spring, There has been proposed a structure in which a spring mounting portion having a flat portion is provided so as to attach a mounting spring to the flat portion of the spring mounting portion (Patent Document 1).

また、係止に際しては、埋め込み穴にコイルばねを用いて装着したものも提案されている(特許文献２)。特許文献２は、照明器具自体の取り付けに関するものではないが、埋め込み穴目隠し用プレートをコイルばねにより、埋め込み穴に装着したものを提案している。   In addition, there has been proposed a method in which a coil spring is attached to the embedded hole for locking (Patent Document 2). Patent Document 2 does not relate to the mounting of the luminaire itself, but proposes that the embedded hole blinding plate is attached to the embedded hole by a coil spring.

いずれの場合にも、埋込穴の側面（切断面）または、その取付け板の上方のエッジに板バネを押し当てるようにした構造が一般的である。   In any case, a structure in which a leaf spring is pressed against the side surface (cut surface) of the embedding hole or the upper edge of the mounting plate is common.

このように、従来品のほとんどは埋込穴の側面（切断面）または、その取付け板の上方のエッジを押しあてる板バネが一般的である。   Thus, most of the conventional products are generally leaf springs that press the side surface (cut surface) of the embedding hole or the upper edge of the mounting plate.

特開平9-134611号公報Japanese Patent Laid-Open No. 9-134611 特開平8-180725号公報JP-A-8-80725

このように、従来埋め込み型の照明器具では、開口の縁に沿ってばね体を設け、据付時に取付け穴の内周に押圧するという方法がとられている。この場合、十分な付勢を得るためにばね体の剛性を大きくする必要があるが、取付け時に取付け穴に挿入できるようにばね体を筐体に近づけるための力が強くなることから、ばね体を長くすることで、少ない力で筐体に近づけるようにしたものが多い。この場合、ばね体は長くかつ、その先端は天井懐側へ向かうため、狭い天井裏への設置は困難となる。
本発明は前記実情に鑑みてなされたもので、天井裏が狭い場合にも、十分な付勢力で取り付けることのできる埋め込み型照明器具を提供することを目的とする。 Thus, in the conventional embedded type lighting fixture, a method is adopted in which a spring body is provided along the edge of the opening and pressed against the inner periphery of the mounting hole at the time of installation. In this case, it is necessary to increase the rigidity of the spring body in order to obtain a sufficient bias. However, since the force to bring the spring body closer to the housing is increased so that it can be inserted into the mounting hole at the time of mounting, Many are designed to be closer to the housing with less force by making the length longer. In this case, since the spring body is long and the tip thereof is directed toward the ceiling, the installation on a narrow ceiling becomes difficult.
The present invention has been made in view of the above circumstances, and an object thereof is to provide an embedded lighting fixture that can be attached with a sufficient biasing force even when the ceiling is narrow.

そこで本発明では、取付け前は、ばね体が筐体よりも下方に下がっており、取付け後は、ばね体の反発により、取付け部を上方より押す力がかかり、照明器具を付勢しつつ固定するものである。
ここでばね体は、薄型の器具を実現するためには、１つの押さえ部に対して、コイル部を２箇所つけ、コイル部の径を小さくしつつ、線径も押さえて応力を分散させ荷重を分担させてもたすのが有効である。場合によっては、器具にばね体を複数設けるようにしてもよい。また、ばね体の先端であって取付け板に接触する部分に弾性材（ゴムなど）をつける事により、照明器具が取付け穴内で回されたり、振動などで回るのを防止して、線がよじれたりするのを、防止することができる。 Therefore, in the present invention, the spring body is lowered below the housing before the attachment, and after the attachment, a force pushing the attachment portion from above is applied by the repulsion of the spring body, and the lighting fixture is fixed while being urged. To do.
Here, in order to realize a thin instrument, the spring body is provided with two coil portions for one pressing portion, and while reducing the diameter of the coil portion, the wire diameter is also suppressed and the stress is dispersed and the load is applied. It is effective to share these. In some cases, a plurality of spring bodies may be provided on the instrument. In addition, by attaching an elastic material (rubber, etc.) to the tip of the spring body that contacts the mounting plate, the lighting fixture is prevented from rotating in the mounting hole or rotating due to vibration, etc. Can be prevented.

すなわち、本発明の照明器具は、発光部と、前記発光部を収容する開口及び開口と対向する底面と、側面とを有する筐体と、前記筐体の前記底面近傍で支点を構成するように第１の端部を取り付けられ、第２の端部が、前記筐体の前記側面よりも外方で、前記筐体の前記底面側から開口に向かう方向に押圧力を付勢するばね体とを有する。
この構成により、筐体の底面近傍で支点を構成するように第１の端部を取り付けられた、ばね体を取付け穴の奥で天井面に押し付けながら挿入することで弾性的に固定しているため、支点からの距離が大きいことで、より小さな力で効率よく挿入し、取付け穴に照明器具を固定することができる。 That is, the luminaire of the present invention forms a fulcrum in the vicinity of the bottom surface of the housing, the housing having the light emitting portion, the opening accommodating the light emitting portion, the bottom surface facing the opening, and the side surface. A spring body to which a first end portion is attached and a second end portion urges a pressing force in a direction from the bottom surface side of the housing toward the opening, outward from the side surface of the housing; Have
With this configuration, the first end portion is attached so as to form a fulcrum in the vicinity of the bottom surface of the casing, and the spring body is elastically fixed by being inserted into the mounting hole while being pressed against the ceiling surface.

With this configuration, the insertion can be efficiently performed by inserting the bent portion, which extends in the direction parallel to the opening when opened, while pressing it against the ceiling surface at the back of the mounting hole.

また、本発明は、上記照明器具において、前記ばね体が、前記第２の端部に弾性材を有する。
この構成により第２の端部に弾性材を有することで、取付け穴内で照明器具が回されたり、振動などで回るのを防止して、線がよじれたりするのを、防止することができる。 Moreover, this invention WHEREIN: In the said lighting fixture, the said spring body has an elastic material in a said 2nd edge part.
By having an elastic material at the second end with this configuration, it is possible to prevent the lighting apparatus from being rotated in the mounting hole or from being rotated by vibration or the like, thereby preventing the wire from being kinked.

また、本発明は、上記照明器具において、前記ばね体が、前記第１の端部が、コイル状に巻回されたコイルばねを構成する。
この構成により、コイルばねを用いることで、天井板と屋根裏との間の距離が小さい場合にも、微小スペースでより復元力の高いばね体を構成しているため、固定力が向上する。 Moreover, this invention comprises the coil spring by which the said 1st end part was wound by the coil shape in the said lighting fixture.
With this configuration, by using the coil spring, even when the distance between the ceiling board and the attic is small, the spring body having a higher restoring force is configured in a minute space, so that the fixing force is improved.

また、本発明は、上記照明器具において、前記ばね体が、前記筐体の底部近傍に設けられた２個の糸ばねで構成されており、前記各糸ばねは、折り曲げ部を有する２重構造で構成され、折り曲げ部が前記第２の端部を構成し、前記第１の端部はそれぞれコイル状に巻回された１対のコイルばねを構成する。
この構成により、１つの押さえ部に対して、コイル部を２箇所つけ、コイル部の径を小さくしつつ、線径も押さえて応力を分散させ荷重分担させてもたすことができる。 Further, the present invention provides the above lighting apparatus, wherein the spring body is composed of two thread springs provided in the vicinity of the bottom of the housing, and each thread spring has a double structure having a bent portion. The bent portion constitutes the second end portion, and the first end portion constitutes a pair of coil springs wound in a coil shape.

また、本発明の照明器具の装着方法は、発光部と、前記発光部を収容する開口及び開口と対向する底面と、側面とを有する筐体と、前記筐体の前記底面近傍で支点を構成するように第１の端部を取り付けられ、第２の端部が、前記筐体の前記側面よりも外方で、前記筐体の前記底面側から開口に向かう方向に押圧力を付勢するばね体とを有する照明器具を、前記ばね体が前記筐体よりも前記底面側に伸張するように付勢しながら、前記取付け穴に挿入し、前記取付け穴の下方端で係止し、前記押圧力によって前記照明器具を前記取付け穴に固定する。
この構成により、筐体の底面で支点を構成するように第１の端部を取り付けられた、ばね体を取付け穴の奥で天井面に押し付けながら挿入することで弾性的に固定しているため、支点からの距離が大きいことで、より小さな力で効率よく挿入し、取付け穴に照明器具を固定することができる。 Further, the mounting method of the lighting fixture of the present invention includes a light emitting part, an opening that accommodates the light emitting part, a bottom face that faces the opening, a side face, and a fulcrum in the vicinity of the bottom face of the case The first end is attached so that the second end urges the pressing force in the direction from the bottom surface side of the housing toward the opening, outside the side surface of the housing. A lighting fixture having a spring body is inserted into the mounting hole while being urged so that the spring body extends toward the bottom side of the housing, and is locked at the lower end of the mounting hole. The lighting apparatus is fixed to the mounting hole by a pressing force.
With this configuration, the first end is attached so as to form a fulcrum on the bottom surface of the housing, and the spring body is elastically fixed by inserting it while pressing it against the ceiling surface behind the attachment hole. Since the distance from the fulcrum is large, it can be efficiently inserted with a smaller force and the luminaire can be fixed in the mounting hole.

本発明の照明器具によれば、ばね体が筐体の底面近傍に設けられるので、ばね体が長くとも据付時には、その先端が器具の開口縁に向かうため懐の狭い天井裏への設置が可能となる。   According to the lighting fixture of the present invention, since the spring body is provided near the bottom surface of the housing, even when the spring body is long, the tip of the spring body is directed to the opening edge of the fixture so that it can be installed on the back of a narrow ceiling.

図１及び図２において、本実施の形態の照明器具は、それぞれ円筒状に形成された筐体１０と、この筐体１０の開口面近傍に設けられた枠体１１と、ばね体３０とを具備している。すなわちこの照明器具は、ＬＥＤ光源からなる発光部２０と、この発光部２０を収容する開口１０ａ及び開口と対向する底面１０ｂと、側面１０ｃとを有する筐体１０と、この筐体１０の前記底面１０ｂ近傍で支点を構成するように第１の端部３１を取り付けられ、第２の端部３２が、筐体１０の側面１０ｃの外表面よりも外方で、この筐体１０の底面１０ｂ側から開口１０ａに向かう方向に押圧力を付勢するばね体３０とを有する。   1 and 2, the lighting apparatus of the present embodiment includes a casing 10 formed in a cylindrical shape, a frame body 11 provided in the vicinity of the opening surface of the casing 10, and a spring body 30. It has. That is, the lighting fixture includes a light emitting unit 20 made of an LED light source, an opening 10a that accommodates the light emitting unit 20, a bottom surface 10b that faces the opening, and a side surface 10c, and the bottom surface of the housing 10. The first end 31 is attached so as to form a fulcrum in the vicinity of 10b, and the second end 32 is outside the outer surface of the side surface 10c of the housing 10 and on the bottom surface 10b side of the housing 10 And a spring body 30 that urges a pressing force in a direction toward the opening 10a.

またこのばね体３０は図３に要部拡大図を示すように、筐体１０の底部１０ｂ近傍に設けられた２個の糸ばねで構成されており、前記各糸ばねは、折り曲げ部を有する２重構造で構成され、折り曲げ部が前記第２の端部を構成し、前記第１の端部３１はそれぞれコイル状に巻回された１対のコイルばねを構成している。そして第２の端部３２の外側は弾性ゴムで構成されたカバー３３が装着されている。なおこのコイルばねは、ステンレス鋼線等のばね材から形成され、筐体１０の底面１０ｂと天井に形成された取付け穴１０１との間に配設されて、天井板１００に押圧力を与える。また、カバー３３(図５参照)により、天井板１００の上面とカバー３３との間で摩擦力を発生させ、天井板１００の上面に板ばねを弾性的に固定する。なお、コイルばねは、さらばね、板ばね、ゴム等の他のばね手段で代替することもできる。   Further, as shown in the enlarged view of the main part in FIG. 3, the spring body 30 is composed of two thread springs provided in the vicinity of the bottom 10b of the housing 10, and each thread spring has a bent portion. It has a double structure, and the bent portion constitutes the second end portion, and the first end portion 31 constitutes a pair of coil springs wound in a coil shape. A cover 33 made of elastic rubber is attached to the outside of the second end portion 32. The coil spring is formed of a spring material such as stainless steel wire, and is disposed between the bottom surface 10b of the housing 10 and the mounting hole 101 formed in the ceiling, and applies a pressing force to the ceiling plate 100. Further, a friction force is generated between the upper surface of the ceiling plate 100 and the cover 33 by the cover 33 (see FIG. 5), and the leaf spring is elastically fixed to the upper surface of the ceiling plate 100. The coil spring can be replaced with other spring means such as a spring spring, a leaf spring, and rubber.

筐体１０は、図４に分解斜視図を示すように、光源である１乃至複数のＬＥＤユニットからなる発光部２０と、ＬＥＤユニットの放射光を図における下方に反射させる反射板２１と、ＬＥＤユニットで発生する熱を放散させるための放熱シート２３と、ＬＥＤユニットから放射された照明光を透過する略円形のパネル２２と、ＬＥＤユニットを点灯させるための電力を供給する電源ユニット(図示せず)を収納する。２４は背面板、２６はビスである。   As shown in an exploded perspective view in FIG. 4, the housing 10 includes a light emitting unit 20 including one or more LED units that are light sources, a reflecting plate 21 that reflects the emitted light of the LED units downward in the drawing, and an LED. A heat radiating sheet 23 for dissipating the heat generated by the unit, a substantially circular panel 22 that transmits the illumination light emitted from the LED unit, and a power supply unit (not shown) that supplies power for lighting the LED unit ). Reference numeral 24 is a back plate, and 26 is a screw.

ＬＥＤユニットは、プリント基板に実装され、電源ユニットから不図示の配線を介して電力が供給されて点灯し、パネル２２を通して図の下方に照明光を照射する。   The LED unit is mounted on a printed circuit board, is turned on when power is supplied from a power supply unit via a wiring (not shown), and illuminates illumination light downward through the panel 22 in the figure.

反射板２１は、例えば、光沢のあるアルミニウム等の金属板を用いて傘状に形成され、ＬＥＤユニットから放射された照明光を図の下方に効率良く照射する。   The reflector 21 is formed in an umbrella shape using, for example, a glossy metal plate such as aluminum, and efficiently irradiates the illumination light emitted from the LED unit downward in the drawing.

放熱シート２３は、熱伝導性に優れたアルミニウム等の金属材をシート状に形成したものであり、ＬＥＤユニットの背部に設置されて、ＬＥＤユニットが点灯した際に発生する熱を放散させる。   The heat radiating sheet 23 is formed by forming a metal material such as aluminum having excellent thermal conductivity into a sheet shape, and is installed on the back of the LED unit to dissipate heat generated when the LED unit is turned on.

パネル２２は、例えば、透明なアクリル樹脂やポリカーボネート樹脂等を略円板状に形成したもので、開口部１０ａを通して外部に露出させた状態で配置される。   The panel 22 is made of, for example, a transparent acrylic resin, polycarbonate resin or the like formed in a substantially disc shape, and is disposed in a state of being exposed to the outside through the opening 10a.

筐体１０は、下部に開口１０ａを有し、天井板１００に設けられた取付け穴１０１の周囲に密着させる枠部１１と、筐体１０の底面１０ｂ近傍に突設され、枠部１１との間で天井板１００を狭持するばね体３０を備える。   The housing 10 has an opening 10a in the lower portion, a frame portion 11 that is in close contact with the periphery of the mounting hole 101 provided in the ceiling plate 100, and a projection that is provided near the bottom surface 10b of the housing 10. A spring body 30 that holds the ceiling plate 100 therebetween is provided.

次に、このように構成された照明器具を天井板１００に形成された取付け穴１０１に装着する装着工程について、図５を用いて説明する。
まず図５（ａ）に示すように、初期状態はばね体が筐体１０の開口１０ａよりも下方に位置するように製造される。
ついで図５（ｂ）に示すように、ばね体３０を付勢して、ばね体３０が筐体１０の底面１０ｂよりも上方に位置するようにし、さらに矢印Ａで示すように内側に付勢しつつ、天井板１００の取付け穴１０１に挿入する。 Next, a mounting process for mounting the thus configured lighting fixture in the mounting hole 101 formed in the ceiling plate 100 will be described with reference to FIG.
First, as shown in FIG. 5A, the initial state is manufactured such that the spring body is positioned below the opening 10 a of the housing 10.
Next, as shown in FIG. 5B, the spring body 30 is urged so that the spring body 30 is positioned above the bottom surface 10b of the housing 10, and further urged inward as indicated by an arrow A. However, it is inserted into the mounting hole 101 of the ceiling board 100.

この挿入過程は図５（ｃ）および図５（ｄ）に示すように、順次、第２の端部の位置を水平移動によりずらしつつ、拡がっていき、筐体の開口１０ａの周囲の枠体１１が取付け穴１０１に係止されて図５（ｅ）に示すように固定される。
このようにして、容易に強固な装着が可能となる。 As shown in FIGS. 5 (c) and 5 (d), this insertion process is sequentially expanded while shifting the position of the second end portion by horizontal movement, and the frame around the opening 10a of the housing. 11 is locked in the mounting hole 101 and fixed as shown in FIG.
In this way, a strong mounting can be easily performed.

この構成により、筐体１０の底面１０ｂの周縁部で支点を構成するように第１の端部１を取り付けられた、ばね体を取付け穴の奥で天井板１００に押し付けながら挿入することで弾性的に固定しているため、支点からの距離が大きいことで、より小さな力で効率よく挿入し、取付け穴１０１に照明器具を固定することができる。そしてこの第１の端部は、コイルを構成しており、しかも２つのコイルばねが並置された構造をとるため、力が分散される上、復元力も大きく、大きな力で天井板１００に対して付勢することができる。
このように、コイルばねを用いることで、天井板１００と屋根裏に設けられる断熱剤２００との間の距離Ｃが小さい場合にも、微小スペースでより復元力の高いばね体を構成しているため、固定力が向上する。 With this configuration, the first end 1 is attached so as to form a fulcrum at the peripheral edge of the bottom surface 10b of the housing 10, and the spring body is elastically inserted by pressing it against the ceiling plate 100 behind the attachment hole. Therefore, since the distance from the fulcrum is large, it can be efficiently inserted with a smaller force, and the luminaire can be fixed to the mounting hole 101. The first end portion constitutes a coil and has a structure in which two coil springs are juxtaposed, so that the force is dispersed and the restoring force is large, and the ceiling plate 100 can be applied with a large force. Can be energized.
As described above, by using the coil spring, even when the distance C between the ceiling plate 100 and the heat insulating agent 200 provided in the attic is small, a spring body having a higher restoring force is formed in a minute space. , The fixing force is improved.

また、ばね体３０の第２の端部３２に折り曲げ部を形成しているため、この部分がばね体を取付け穴１０１に合わせるための誘導部となり、装着が容易となる。   Moreover, since the bent part is formed in the 2nd end part 32 of the spring body 30, this part becomes a guide part for matching a spring body with the attachment hole 101, and mounting | wearing becomes easy.

一方、照明器具を取り外す際には、この第２の端部３２の折り曲げ部によって、図５（ｂ）に示したような形状で係止されることになり、照明器具の落下を防止することができる。   On the other hand, when the luminaire is removed, the bent portion of the second end portion 32 is locked in the shape as shown in FIG. 5B to prevent the luminaire from falling. Can do.

なお、前記実施の形態では２重構造のコイルばねを用いたが１重構造のコイルばねであっても良く、またコイルばねに限定されることなく、通常の弾性部材で構成されていてもよい。   In the above-described embodiment, a double-structured coil spring is used, but a single-structure coil spring may be used, and the present invention is not limited to a coil spring, and may be composed of a normal elastic member. .

（実施の形態２）

FIG. 6 is a diagram showing a schematic configuration of a lighting fixture according to Embodiment 2 of the present invention. In FIG. 6, the same components as those in FIG. 1 of the first embodiment are denoted by the same reference numerals and description thereof is omitted.

本実施の形態では図６に示すように、コイルばねに代えて板ばね１３０を用いた点が異なるのみであり、他は前記実施の形態１と同様に構成される。
また、前記実施の形態では、光源としてＬＥＤを用いたが、ＬＥＤに限定されることなく、有機ＥＬ素子、放電灯など、いかなる光源にも適用可能である。 In the present embodiment, as shown in FIG. 6, the only difference is that a leaf spring 130 is used instead of the coil spring, and the rest is configured in the same manner as in the first embodiment.
Moreover, although LED was used as a light source in the said embodiment, it is applicable to any light sources, such as an organic EL element and a discharge lamp, without being limited to LED.
