Description

本発明は、光源の前方に取り付けられた前面パネルが器具本体に対して着脱可能な照明器具に関するものである。   The present invention relates to a lighting fixture in which a front panel attached in front of a light source is detachable from a fixture main body.

従来の照明器具は、光源である蛍光灯を収容する器具本体と、光源の前方を覆う前面カバーとを有している。
前面カバーは、支持機構を介して器具本体に取り付けられ、かつ、器具本体に対して着脱可能となっている（例えば特許文献１参照）。 The conventional lighting fixture has a fixture main body that accommodates a fluorescent lamp that is a light source, and a front cover that covers the front of the light source.
The front cover is attached to the instrument main body via a support mechanism and is detachable from the instrument main body (see, for example, Patent Document 1).

支持機構は、器具本体の内壁に固定された金属製の支持台と、前面カバーを支持台から吊り下げるためのバネ部材とを有している。
支持台は、水平壁および垂直壁を備える断面略Ｌ字形状とされ、垂直壁が器具本体の内面に固定されている。水平壁には、左右に対向する一対の摺接孔が設けられている。
一方、バネ部材は、線材が巻回されたリング部から一対の腕部が拡開するように延在する略Ｖ字状に形成されている。腕部の先端部は、それぞれ折り曲げられて停止が形成されている。 The support mechanism includes a metal support base fixed to the inner wall of the instrument body and a spring member for suspending the front cover from the support base.
The support base has a substantially L-shaped cross section including a horizontal wall and a vertical wall, and the vertical wall is fixed to the inner surface of the instrument body. The horizontal wall is provided with a pair of sliding contact holes facing left and right.
On the other hand, the spring member is formed in a substantially V shape extending so that the pair of arms expands from the ring portion around which the wire is wound. The distal end of the arm is bent to form a stop.

このような照明器具は、バネ部材の腕部が近接するようにリング部に外力を加えながら、リング部が水平壁よりも下方になるように、バネ部材の腕部をそれぞれ支持台の摺接孔に係止させると、腕部を初期位置まで拡開させて戻そうとするリング部の弾性力により、腕部が摺接孔を強圧し、その結果としてリング部が上方に引き上げられ、これにより前面カバーの枠体が器具本体の下面に当接した状態で支持される。   In such a lighting apparatus, while applying an external force to the ring part so that the arm part of the spring member is close, the arm part of the spring member is slidably contacted with the support base so that the ring part is below the horizontal wall. When locked in the hole, the arm part strongly pressurizes the sliding contact hole by the elastic force of the ring part that attempts to expand the arm part back to the initial position, and as a result, the ring part is lifted upward. Thus, the frame body of the front cover is supported in a state of being in contact with the lower surface of the instrument body.

また、照明器具は、前面カバーを下方に引き下げると、腕部を近接させながらバネ部材が下方に引き下げられ、停止部が支持台の上面に係止されて前面カバーの下降が規制、これにより前面カバーが落下することはない。
特開昭５６−２２００１号公報（第４図） In addition, when the front cover is pulled down, the lighting device pulls the spring member downward while bringing the arms close together, and the stop is locked to the upper surface of the support base, thereby restricting the lowering of the front cover. The cover will not fall.
Japanese Patent Laid-Open No. Sho 56-22001 (FIG. 4)

しかしながら、前述した特許文献１の照明器具は、前面カバーの重量や寸法等に対応して、線径や寸法等が異なる複数種類のバネ部材が選択的に用いられているため、あらかじめ用意しておくバネ部材の種類が多数化し、これにより製造コストが高くなるという問題があった。   However, the lighting fixture of Patent Document 1 described above is prepared in advance because a plurality of types of spring members having different wire diameters and dimensions are selectively used in accordance with the weight and dimensions of the front cover. There is a problem that the number of types of spring members to be placed increases, which increases the manufacturing cost.

また、特許文献１の照明器具は、器具本体に対する引き上げ力を変更する場合、バネ部材を交換する必要があるが、交換するバネ部材が既存の支持台に合致しない場合には交換を行えず、引き上げ力を変更できないという問題があった。   Further, the lighting fixture of Patent Document 1 needs to replace the spring member when changing the lifting force with respect to the fixture body, but cannot be replaced if the spring member to be replaced does not match the existing support base, There was a problem that the lifting force could not be changed.

本発明は、従来の問題を解決するためになされたもので、製造コストを低減できるとともに、容易に引き上げ力を変更できる照明器具を提供することを目的とする。   The present invention has been made to solve the conventional problems, and an object of the present invention is to provide a lighting apparatus that can reduce the manufacturing cost and can easily change the lifting force.

本発明の照明器具は、前面パネルと、前記前面パネルを保持するバネ部材とを備える照明器具において、前記バネ部材のバネの反力を調整するバネ反力調整部材を設けたことを特徴としている。   The luminaire of the present invention is characterized in that in a luminaire including a front panel and a spring member that holds the front panel, a spring reaction force adjusting member that adjusts a reaction force of the spring of the spring member is provided. .

このような本発明においては、バネ反力調整部材によりバネの反力を調整できるため、あらかじめ複数種類のバネ部材を用意しておく必要性が解消されることになる。   In the present invention, since the spring reaction force can be adjusted by the spring reaction force adjusting member, the necessity of preparing a plurality of types of spring members in advance is eliminated.

また、本発明の照明器具は、前記バネ反力調整部材は、器具本体に対して上下方向に移動する取付金具であることを特徴としている。   Moreover, the lighting fixture of the present invention is characterized in that the spring reaction force adjusting member is a mounting bracket that moves in the vertical direction with respect to the fixture body.

このような本発明においては、バネ反力調整部材が器具本体に対して上下方向に移動するため、バネ部材を係止する位置を変更できることになり、これによりバネ反力を調整できることとなる。   In such this invention, since a spring reaction force adjustment member moves to an up-down direction with respect to an instrument main body, the position which latches a spring member can be changed, and, thereby, a spring reaction force can be adjusted.

さらに、本発明の照明器具は、前記バネ反力調整部材は、前記バネ部材の拡開幅を規制するバネ保持部の規制幅を調整可能な取付金具であることを特徴としている。   Furthermore, the lighting fixture of the present invention is characterized in that the spring reaction force adjusting member is a mounting bracket capable of adjusting a regulation width of a spring holding part that regulates an expansion width of the spring member.

このような本発明においては、バネ保持部の規制幅を調整可能であるため、これによってもバネ反力の調整を容易に行えることになる。   In the present invention, since the regulation width of the spring holding portion can be adjusted, the spring reaction force can be easily adjusted by this.

本発明は、前面カバーを器具本体に取り付けるためのバネ部材の支持位置をバネ反力調整部材によって変えることができるため、複数種類の照明器具に対して単一のバネ部材を共通して採用でき、これにより製造コストを低減でき、かつ、バネ反力調整部材によってバネ部材の係止位置を変更できるため、容易に引き上げ力の調整を行えるという効果を有する照明器具を提供できるものである。   In the present invention, since the support position of the spring member for attaching the front cover to the fixture body can be changed by the spring reaction force adjusting member, a single spring member can be commonly used for a plurality of types of lighting fixtures. Thus, the manufacturing cost can be reduced, and the locking position of the spring member can be changed by the spring reaction force adjusting member, so that it is possible to provide a lighting apparatus having an effect of easily adjusting the lifting force.

（第１実施形態）
以下、本発明に係る第１実施形態について、図面を用いて説明する。
図１（Ａ）は本発明に係る第１実施形態の照明器具のバネ反力調整部材の正面図、図１（Ｂ）は図１（Ａ）中Ｂ方向から見た側面図、図２（Ａ）は取付金具の正面図、図２（Ｂ）は図２（Ａ）中Ｂ方向から見た側面図、図２（Ｃ）は平面図である。 (First embodiment)
Hereinafter, a first embodiment according to the present invention will be described with reference to the drawings.
1A is a front view of a spring reaction force adjusting member of the lighting apparatus according to the first embodiment of the present invention, FIG. 1B is a side view seen from the direction B in FIG. 1A, and FIG. 2A is a front view of the mounting bracket, FIG. 2B is a side view seen from the direction B in FIG. 2A, and FIG. 2C is a plan view.

図１に示すように、照明器具１０は、例えば蛍光灯等の光源（図示せず）を収容する器具本体１１と、光源の前方を覆う前面カバー１２と、器具本体１１に対して前面カバー１２を着脱可能に取り付けるためのバネ部材２１とを備えている。   As shown in FIG. 1, the lighting fixture 10 includes a fixture main body 11 that houses a light source (not shown) such as a fluorescent lamp, a front cover 12 that covers the front of the light source, and a front cover 12 for the fixture main body 11. And a spring member 21 for detachably attaching.

バネ部材２１は、線材が巻回されたリング部２１ａから一対の腕部２１ｂ、２１ｂが拡開するように延在する略Ｖ字状に形成されている。腕部２１ｂ、２１ｂの先端部は、それぞれ折り曲げられて停止部２１ｃ、２１ｃが形成されている。
このバネ部材２１は、本発明に基づくバネ反力調整部材である取付金具２０を介して器具本体１１に支持されている。 The spring member 21 is formed in a substantially V shape extending so that the pair of arm portions 21b and 21b expand from the ring portion 21a around which the wire is wound. The distal end portions of the arm portions 21b and 21b are bent to form stop portions 21c and 21c, respectively.
This spring member 21 is supported by the instrument body 11 via a mounting bracket 20 which is a spring reaction force adjusting member based on the present invention.

図２にも示すように、取付金具２０は、垂直壁２３および水平壁２４を備える断面略Ｌ字形状とされ、垂直壁２３が器具本体１１を構成する内壁１３の内面１３ａに固定されている。
垂直壁２３は、上下方向に複数本（ここでは、例えば２本）の垂直溝２５ａが形成されているとともに、各垂直溝２５ａから水平に複数本（ここでは、例えば３本）の水平溝２５ｂが形成されている。垂直溝２５ａおよび水平溝２５ｂは、取付金具２０を器具本体１１に固定するための固定ネジ２６のネジ軸部が通過できる幅を有している。
水平壁２４は、略コ字状の切欠２２ａ、２２ａが向かい合う平面略Ｃ字状とされている。 As shown in FIG. 2, the mounting bracket 20 has a substantially L-shaped cross section including a vertical wall 23 and a horizontal wall 24, and the vertical wall 23 is fixed to the inner surface 13 a of the inner wall 13 constituting the instrument body 11. .
The vertical wall 23 has a plurality of (here, for example, two) vertical grooves 25a formed in the vertical direction, and a plurality of (here, for example, three) horizontal grooves 25b horizontally from each vertical groove 25a. Is formed. The vertical groove 25a and the horizontal groove 25b have a width through which the screw shaft portion of the fixing screw 26 for fixing the mounting bracket 20 to the instrument body 11 can pass.
The horizontal wall 24 is substantially C-shaped in a plane where substantially U-shaped notches 22a and 22a face each other.

図１に戻って、バネ部材２１は、リング部２１ａを中心として腕部２１ｂ、２１ｂを互いに近接させるような外力に対して、腕部２１ｂ、２１ｂが初期位置に復帰するまで拡開する方向（図１（Ａ）中矢印Ａ方向）に弾性力が発生する。
このようなバネ部材２１は、腕部２１ｂ、２１ｂが互いに近接するようにリング部２１ａに外力が加えられながら、リング部２１ａが水平壁２４よりも下方になるように、腕部２１ｂ、２１をそれぞれ水平壁２４の切欠２２ａ、２２ａに摺接させながら係止される。 Returning to FIG. 1, the spring member 21 expands until the arm portions 21 b and 21 b return to the initial position against an external force that brings the arm portions 21 b and 21 b close to each other with the ring portion 21 a as the center ( Elastic force is generated in the direction of arrow A in FIG.
Such a spring member 21 allows the arm portions 21b and 21 to be positioned below the horizontal wall 24 while an external force is applied to the ring portion 21a so that the arm portions 21b and 21b are close to each other. The horizontal walls 24 are locked while being brought into sliding contact with the notches 22a and 22a.

なお、バネ部材２１のリング部２１ａに引き下げ力が作用しても、腕部２１ｂの先端の停止部２１ｃが取付金具２０の係止部２２ａに引っ掛かるので、バネ部材２１が取付金具２０から脱落することはない。
また、前面カバー１２は、その内側に略Ｊ字状に形成されたバネ取付金具１４が先端部を下方に向けて取り付けられている。そして、前面カバー１２は、バネ取付金具１４の先端をバネ部材２１のリング部２１ａに係止させることにより、器具本体１１に接続される。 Even if a pulling force is applied to the ring portion 21 a of the spring member 21, the stop portion 21 c at the tip of the arm portion 21 b is hooked on the locking portion 22 a of the mounting bracket 20, so that the spring member 21 falls off the mounting bracket 20. There is nothing.
Further, the front cover 12 is attached with a spring mounting bracket 14 formed in a substantially J-shape on the inner side thereof with the tip portion directed downward. The front cover 12 is connected to the instrument main body 11 by locking the tip of the spring mounting bracket 14 to the ring portion 21 a of the spring member 21.

前面カバー１２を天井等に固定された器具本体１１に取り付けるにあたっては、器具本体１１と前面カバー１２との相対位置が適切となるように、固定ネジ２６に対して複数の水平溝２５ｂのうちのいずれかを選択することにより、器具本体１１に対する取付金具２２の高さを設定する。
ここで、バネ部材２１によるバネ反力（前面カバー１２に対する引き上げ力）を大きくする場合には、取付金具２２を器具本体１１に対して下方に取り付ける。一方、バネ反力を弱くする場合には、取付金具２２を器具本体１１に対して上方に取り付ける。 In attaching the front cover 12 to the instrument main body 11 fixed to the ceiling or the like, the fixing screw 26 has a plurality of horizontal grooves 25b so that the relative position between the instrument main body 11 and the front cover 12 is appropriate. By selecting one of them, the height of the mounting bracket 22 with respect to the instrument body 11 is set.
Here, when the spring reaction force by the spring member 21 (the pulling force with respect to the front cover 12) is increased, the mounting bracket 22 is attached to the lower side of the instrument body 11. On the other hand, when the spring reaction force is weakened, the mounting bracket 22 is mounted upward with respect to the instrument body 11.

次いで、前面カバー１２にバネ取付金具１４を介して接続されたバネ部材２１の腕部２１ｂ、２１ｂを互いに近接させ、これらの腕部２１ｂ、２１ｂを係止部２２ａ、２２ａに係止させる。
最後に、前面カバー１２を押し上げると、腕部２１ｂ、２１ｂが初期位置に復帰するまで生ずる弾性力により取付金具２０に対して自己上昇するバネ部材２１に追従して前面カバー１２が器具本体１１に当接するまで上昇し、所定位置に配置される。 Next, the arm portions 21b and 21b of the spring member 21 connected to the front cover 12 via the spring mounting bracket 14 are brought close to each other, and these arm portions 21b and 21b are locked to the locking portions 22a and 22a.
Finally, when the front cover 12 is pushed up, the front cover 12 follows the spring member 21 that self-raises with respect to the mounting bracket 20 by the elastic force generated until the arm portions 21b and 21b return to the initial position. It rises until it abuts and is placed at a predetermined position.

以上のような照明器具１０は、あらかじめ締結された固定ネジ２６を一時的に緩めてから、固定ネジ２６が垂直溝２５ａに位置するように取付金具２０を右方に移動させ（図２（Ａ）中、二点鎖線参照）、次いで取付金具２０を上下方向へ移動させてから所望の水平溝２５ｂに対応する位置で取付金具２０を左方に移動させ、該当する水平溝２５ｂの突き当たりにネジ軸部が当接した状態で固定ネジ２６を締結することにより、取付金具２０の上下位置を変更できる。このような取付金具２０は、上下に配列された水平溝２５ｂの数だけ、固定位置を選択可能となっている。
なお、図１および図２（Ａ）では、器具本体１１に対して取付金具２０を最も下方に固定した状態が示されている。 The lighting fixture 10 as described above temporarily loosens the fixing screw 26 fastened in advance, and then moves the mounting bracket 20 to the right so that the fixing screw 26 is positioned in the vertical groove 25a (FIG. 2A). ), Refer to the two-dot chain line), then move the mounting bracket 20 up and down, then move the mounting bracket 20 to the left at a position corresponding to the desired horizontal groove 25b, and screw it to the end of the corresponding horizontal groove 25b. The vertical position of the mounting bracket 20 can be changed by fastening the fixing screw 26 with the shaft portion in contact. Such mounting brackets 20 can be selected in fixed positions by the number of horizontal grooves 25b arranged in the vertical direction.
1 and FIG. 2A show a state in which the mounting bracket 20 is fixed to the lowermost side with respect to the instrument main body 11.

以上、説明した照明器具１０によれば、前面カバー１２を器具本体１１に取り付けるためのバネ部材２１の支持位置をバネ反力調整部材である取付金具２０により変更できるため、重量や寸法等が異なる他の前面カバーを器具本体１１に取り付けるにあたって、線径や寸法等が異なる他のバネ部材を用いる必要がなく、従来のように、あらかじめ用意しておくバネ部材の種類が多数化して製造コストが高くなるという問題を解消できる。   As mentioned above, according to the lighting fixture 10 demonstrated, since the support position of the spring member 21 for attaching the front cover 12 to the fixture main body 11 can be changed with the attachment metal fitting 20 which is a spring reaction force adjustment member, a weight, a dimension, etc. differ. When attaching another front cover to the instrument body 11, there is no need to use other spring members having different wire diameters, dimensions, etc., and the number of types of spring members prepared in advance is increased as in the prior art, resulting in reduced manufacturing costs. Can solve the problem of high.

また、前述した照明器具１０によれば、使用状況や経時変化に伴って前面カバー１２を引き上げるためのバネ反力を調整する場合にも容易に対応できる。   Moreover, according to the lighting fixture 10 mentioned above, it can respond easily also when adjusting the spring reaction force for pulling up the front cover 12 with a use condition or a time-dependent change.

（第２実施形態）
次に、本発明に係る第２実施形態について、図面を用いて説明する。
図３（Ａ）は本発明に係る第２実施形態の照明器具のバネ反力調整部材の正面図、図３（Ｂ）は平面図、図３（Ｃ）は側面図である。
なお、前述した第１実施形態と共通する部位には、同じ符号を付して、重複する説明を省略することとする。 (Second Embodiment)
Next, a second embodiment according to the present invention will be described with reference to the drawings.
3A is a front view of a spring reaction force adjusting member of a lighting apparatus according to a second embodiment of the present invention, FIG. 3B is a plan view, and FIG. 3C is a side view.
In addition, the same code | symbol is attached | subjected to the site | part which is common in 1st Embodiment mentioned above, and the overlapping description is abbreviate | omitted.

図３に示すように、第２実施形態の照明器具１０Ｂは、バネ反力調整部材である取付金具３１は、バネ部材２１の腕部２１ｂ、２１ｂを係止するために設けられた一対の係止部３２ａ、３２ａの間隔が調整可能となっている。
取付金具３１は、垂直壁３１ａおよび水平壁３１ｂを備える断面略Ｌ字形状とされ、垂直壁３１ａが器具本体を構成する内壁に固定される。 As shown in FIG. 3, in the luminaire 10B of the second embodiment, the mounting bracket 31 that is a spring reaction force adjusting member includes a pair of engagement members provided to lock the arm portions 21b and 21b of the spring member 21. The interval between the stop portions 32a and 32a can be adjusted.
The mounting bracket 31 has a substantially L-shaped cross section including a vertical wall 31a and a horizontal wall 31b, and the vertical wall 31a is fixed to an inner wall constituting the instrument body.

水平壁３１ｂ、３１ｂは、垂直壁３１ａの下端の左右両端部にそれぞれ設けられていて、ネジ穴（図示省略）を有している。これらの水平部３１ｂ、３１ｂは、それぞれ水平部３１ｂと略同じ幅の板材であるバネ部材係止板３２が積層されている。バネ部材係止板３２の内側端部にはバネ部材２１を係止する係止部３２ａが設けられており、係止部３２ａは互いに対向することになる。また、両バネ部材係止板３２には、長孔のネジ穴３４ａが設けられており、ネジ３４を緩めた状態で互いに接近・離反可能となっている。   The horizontal walls 31b and 31b are respectively provided at the left and right ends of the lower end of the vertical wall 31a and have screw holes (not shown). Each of the horizontal portions 31b and 31b is laminated with a spring member locking plate 32 that is a plate material having substantially the same width as the horizontal portion 31b. A locking portion 32a for locking the spring member 21 is provided at the inner end of the spring member locking plate 32, and the locking portions 32a face each other. The spring member locking plates 32 are each provided with a long screw hole 34a so that the screws 34 can be moved toward and away from each other with the screw 34 loosened.

従って、図３（Ｂ）に示すように、ネジ３４を緩めることにより、両係止部３２ａ、３２ａの間隔を調整することが可能となり、間隔調整後、ネジ３４を締め付けて両バネ部材係止板３２、３２を固定する。
すなわち、一対のバネ部材係止板３２、３２を接近させることにより係止部３２ａの間隔を狭めて、バネ力（引き上げ力）を弱くすることができる。一方、一対のバネ部材係止板３２、３２を離すことにより係止部３２ａの間隔を広げて、バネ力（引き上げ力）を強くすることができる。 Therefore, as shown in FIG. 3B, by loosening the screw 34, it is possible to adjust the interval between the locking portions 32a, 32a. After adjusting the interval, the screw 34 is tightened to lock both spring members. The plates 32 and 32 are fixed.
That is, by bringing the pair of spring member locking plates 32 and 32 close to each other, the interval between the locking portions 32a can be narrowed, and the spring force (lifting force) can be weakened. On the other hand, by separating the pair of spring member locking plates 32, 32, the interval between the locking portions 32a can be widened to increase the spring force (lifting force).

このように、前面カバー１２を器具本体１１に取り付けるバネ部材２１の係止部３２ａの間隔を調整することにより、バネ部材２１のバネ反力を変更できるため、重量や寸法等が異なる他の前面カバーを器具本体に取り付けるにあたって、線径や寸法等が異なる他のバネ部材を用いる必要がないとともに、使用状況や経時変化に伴って前面カバーを引き上げるためのバネ反力を調整する場合にも容易に対応できる。   As described above, the spring reaction force of the spring member 21 can be changed by adjusting the distance between the locking portions 32a of the spring member 21 that attaches the front cover 12 to the instrument main body 11. When attaching the cover to the instrument body, it is not necessary to use other spring members with different wire diameters, dimensions, etc., and it is easy to adjust the spring reaction force to pull up the front cover according to usage conditions and changes over time It can correspond to.

なお、前述した第１実施形態においては取付金具を上下移動させることによりバネ反力を調整可能な構造のみを示し、第２実施形態においてはバネ部材を係止する係止部の間隔を変更可能な構造のみを示したが、取付金具を上下移動させる構造と係止部の間隔を変更可能な構造とが併用された構造も本発明に含まれる。   In the first embodiment described above, only the structure in which the spring reaction force can be adjusted by moving the mounting bracket up and down is shown, and in the second embodiment, the interval between the locking portions for locking the spring member can be changed. Although only a simple structure is shown, a structure in which a structure in which the mounting bracket is moved up and down and a structure in which the interval between the locking portions can be changed is also included in the present invention.

以上のように、本発明の照明器具は、前面カバーに対するバネ部材のバネ反力を変更できるため、重量や寸法等が異なる他の前面カバーを器具本体に取り付けるにあたって、線径や寸法等が異なる他のバネ部材を用いる必要がないとともに、使用状況や経時変化に伴って前面カバーを引き上げるためのバネ反力を調整する場合にも容易に対応できるという効果を有し、器具本体の前方に前面カバーを着脱可能に取り付ける照明器具等として有用である。   As described above, since the lighting fixture of the present invention can change the spring reaction force of the spring member with respect to the front cover, the wire diameter, the size, etc. are different when attaching another front cover having a different weight, size, etc. to the fixture body. There is no need to use another spring member, and it has the effect that it can easily cope with adjusting the spring reaction force to pull up the front cover according to the usage situation and changes over time. It is useful as a lighting fixture or the like for detachably attaching a cover.
