Description

本発明の実施形態は、線ばねを用いたばね装置、およびこのばね装置を用いた照明装置に関する。 An embodiment of the present invention relates to a spring device using a wire spring and a lighting device using the spring device.

従来、例えば、照明装置では、器具本体に光源ユニットを着脱可能に装着するのにばね装置が用いられている。 Conventionally, for example, in a lighting device, a spring device has been used to attach and detach a light source unit to a fixture body.

このようなばね装置には、トーションばねが多く用いられている。しかし、トーションばねは、一方向の回転方向にしか弾性力を得ることができないため、器具本体に光源ユニットを装着する場合、トーションばねを弾性変形させて保持した状態での装着操作が必要となり、使い勝手が悪い場合がある。 Torsion springs are often used in such spring devices. However, since the torsion spring can obtain an elastic force only in one direction of rotation, when the light source unit is attached to the instrument body, it is necessary to perform the attachment operation in a state where the torsion spring is elastically deformed and held. It may not be easy to use.

また、スライド機構を介して線ばねを支持し、この線ばねを引き出した状態で保持され、線ばねを押し戻すことによって弾性力が生じるようにした取付構造があるが、構造が複雑になる問題がある。 In addition, there is a mounting structure in which the wire spring is supported via a slide mechanism, the wire spring is held in a pulled out state, and an elastic force is generated by pushing the wire spring back, but there is a problem that the structure becomes complicated. be.

The lighting device 10 is, for example, a ceiling-mounted lighting fixture. The lighting device 10 includes an appliance main body 11 installed on an installation surface such as a ceiling surface, a light source unit 12 detachably attached to the instrument main body 11, and an instrument main body 11 and a second member which are first members. It is provided with a mounting device 13 for detachably attaching the light source unit 12 and the light source unit 12. The lighting device 10 is formed in a rectangular outer shape. In the present embodiment, the lighting device 10 is formed in, for example, a square outer shape having a length and width of 400 mm.

そして、器具本体11は、例えば1枚の金属板をプレス加工して一体に形成されている。器具本体11は、四角形状の天面部15、この天面部15の周辺部から下方に折曲された側面部16、およびこの側面部16から外側方に向けて断面略L字形に折曲された嵌合突部17を備えている。天面部15には、設置用の取付孔18や、配線孔19などが形成されている。 The instrument body 11 is integrally formed by, for example, pressing one metal plate. The instrument body 11 is bent in a substantially L-shaped cross section from the square top surface portion 15, the side surface portion 16 bent downward from the peripheral portion of the top surface portion 15, and outward from the side surface portion 16. It is provided with a fitting protrusion 17. The top surface portion 15 is formed with a mounting hole 18 for installation, a wiring hole 19, and the like.

器具本体11には、電源ユニット21および端子台22などが配設されている。電源ユニット21は、天面部15の内面である下面で、器具本体11の対向する2辺に沿って配設されている。電源ユニット21の点灯電源出力部からは光源ユニット12側との接続用のコネクタ付ケーブルが引き出されている。そして、電源ユニット21は、外部電源や調光信号などを入力し、調光信号に基づいて外部電源を所定の点灯電源に変換して出力する。また、端子台22は、例えば電源用と信号用の2つが用いられ、天面部15の下面で配線孔19の近傍に配設されている。端子台22と電源ユニット21の電源入力部および信号入力部とが内部配線で電気的に接続されている。端子台22には、器具本体11の設置時に、配線孔19から引き込まれる外部電源供給用の電源線や信号線が接続される。 A power supply unit 21, a terminal block 22, and the like are arranged on the instrument main body 11. The power supply unit 21 is arranged along two opposite sides of the instrument main body 11 on the lower surface which is the inner surface of the top surface portion 15. A cable with a connector for connecting to the light source unit 12 side is pulled out from the lighting power output unit of the power supply unit 21. Then, the power supply unit 21 inputs an external power source, a dimming signal, or the like, converts the external power source into a predetermined lighting power source based on the dimming signal, and outputs the output. Further, for example, two terminal blocks 22 are used, one for power supply and the other for signal, and they are arranged in the vicinity of the wiring hole 19 on the lower surface of the top surface portion 15. The terminal block 22 and the power input section and signal input section of the power supply unit 21 are electrically connected by internal wiring. A power supply line or signal line for external power supply drawn from the wiring hole 19 is connected to the terminal block 22 when the instrument main body 11 is installed.

また、光源ユニット12は、ベースプレート25、このベースプレート25の下面に取り付けられる発光モジュール26、およびこの発光モジュール26を覆ってベースプレート25に取り付けられる透光カバー27を備えている。 Further, the light source unit 12 includes a base plate 25, a light emitting module 26 attached to the lower surface of the base plate 25, and a translucent cover 27 attached to the base plate 25 so as to cover the light emitting module 26.

ベースプレート25は、例えば1枚の金属板をプレス加工して一体に形成されている。ベースプレート25は、四角形状のプレート部29、およびこのプレート部29の周辺部から上方に折曲された嵌合枠部30を備えている。嵌合枠部30は、器具本体11の嵌合突部17の周囲に嵌合可能としている。プレート部29の周辺部には、複数の溝部31が形成されている。各溝部31の縁には、嵌合枠部30に対して透光カバー27をかしめ結合するためのかしめ片32が設けられている。 The base plate 25 is integrally formed by, for example, pressing one metal plate. The base plate 25 includes a rectangular plate portion 29 and a fitting frame portion 30 that is bent upward from the peripheral portion of the plate portion 29. The fitting frame portion 30 can be fitted around the fitting protrusion 17 of the instrument main body 11. A plurality of groove portions 31 are formed in the peripheral portion of the plate portion 29. A caulking piece 32 for caulking and connecting the translucent cover 27 to the fitting frame portion 30 is provided on the edge of each groove portion 31.

発光モジュール26は、四角形状の基板33、およびこの基板33の表面側に実装された複数の発光素子(半導体発光素子)34(図16参照)を備えている。基板33の裏面側をベースプレート25に熱的に接続された状態に取り付けられる。発光モジュール26には給電用のコネクタ付ケーブルが接続されている。このコネクタ付ケーブルは、ベースプレート25の溝部31あるいはベースプレート25に別途設けられる配線孔を通じて、ベースプレート25から引き出され、電源ユニット21から引き出されているコネクタ付ケーブルとコネクタ接続される。 The light emitting module 26 includes a rectangular substrate 33 and a plurality of light emitting elements (semiconductor light emitting elements) 34 (see FIG. 16) mounted on the surface side of the substrate 33. The back surface side of the substrate 33 is attached to the base plate 25 in a state of being thermally connected. A cable with a connector for power supply is connected to the light emitting module 26. This cable with a connector is drawn out from the base plate 25 through a groove 31 of the base plate 25 or a wiring hole separately provided in the base plate 25, and is connected to the cable with a connector drawn out from the power supply unit 21.

透光カバー27は、光透過性を有し、さらに光拡散性を有していてもよい。透光カバー27は、四角形状の下面部35、およびこの下面部35の周辺部から上方に突出する側面部36を有している。側面部36の上端側がベースプレート25の嵌合枠部30に図示しないパッキングを介して嵌合され、複数のかしめ片32によってベースプレート25と透光カバー27とが一体に結合されている。 The translucent cover 27 has light transmissibility and may further have light diffusivity. The translucent cover 27 has a rectangular lower surface portion 35 and a side surface portion 36 projecting upward from the peripheral portion of the lower surface portion 35. The upper end side of the side surface portion 36 is fitted to the fitting frame portion 30 of the base plate 25 via a packing (not shown), and the base plate 25 and the translucent cover 27 are integrally connected by a plurality of caulking pieces 32.

次に、図1および図3に示すように、取付装置13は、光源ユニット12側に取り付けられるばね装置40、および器具本体11側に取り付けられるばね受41を備えている。取付装置13は、ばね装置40とばね受41とを組として、2組用いられている。2組の取付装置13は、2つの電源ユニット21が配置される器具本体11の対向する2辺の位置に対して異なる方向の対向する2辺の位置に対応して配設されている。 Next, as shown in FIGS. 1 and 3, the mounting device 13 includes a spring device 40 mounted on the light source unit 12 side and a spring receiver 41 mounted on the appliance main body 11 side. Two sets of the mounting device 13 are used, with the spring device 40 and the spring receiver 41 as a set. The two sets of mounting devices 13 are arranged corresponding to the positions of the two facing sides in different directions with respect to the positions of the two facing sides of the instrument main body 11 in which the two power supply units 21 are arranged.

そして、ばね装置40は、線ばね44、軸受部材45、および押え部材46を備えている。 The spring device 40 includes a wire spring 44, a bearing member 45, and a pressing member 46.

図3ないし図6に示すように、線ばね44は、例えば金属のばね材料によって形成された線材を曲げ加工して形成されている。ばね材料としては、例えばステンレスが用いられている。線ばね44は、中間のフック部49、このフック部49の両端部から互いに略平行に対向するように折曲された一対のアーム部50、およびこれらアーム部50の端部からそれぞれ外側に向けて折曲された一対の軸部51を有している。 As shown in FIGS. 3 to 6, the wire spring 44 is formed by bending a wire rod formed of, for example, a metal spring material. As the spring material, for example, stainless steel is used. The wire spring 44 has an intermediate hook portion 49, a pair of arm portions 50 bent so as to face substantially parallel to each other from both ends of the hook portion 49, and outwards from the ends of these arm portions 50, respectively. It has a pair of shaft portions 51 that are bent.

フック部49は、略直線状に形成され、その両端から一対のアーム部50が折曲されている。 The hook portion 49 is formed in a substantially linear shape, and a pair of arm portions 50 are bent from both ends thereof.

一対のアーム部50は、先端側に設けられたアームガイド部50a、基端側に設けられたアーム直線部50b、アームガイド部50aとアーム直線部50bとを接続するアーム接続部50c、およびアーム直線部50bとアーム接続部50cとの間でアームガイド部50aよりも基端側に設けられたアーム当接部50dを有している。アームガイド部50aは、図1などに示すように光源ユニット12の内側に向けて折り畳まれる状態で、上方に向けて突出する凸湾曲状に形成されている。アーム当接部50dは、アーム直線部50bとアーム接続部50cとの折曲部で構成されている。 The pair of arm portions 50 includes an arm guide portion 50a provided on the tip side, an arm straight portion 50b provided on the proximal end side, an arm connection portion 50c connecting the arm guide portion 50a and the arm straight portion 50b, and an arm. It has an arm contact portion 50d provided between the straight line portion 50b and the arm connecting portion 50c on the proximal end side of the arm guide portion 50a. As shown in FIG. 1, the arm guide portion 50a is formed in a convex curved shape that protrudes upward in a state of being folded toward the inside of the light source unit 12. The arm contact portion 50d is composed of a bent portion of an arm straight portion 50b and an arm connecting portion 50c.

一対の軸部51は、一対のアーム部50の端部から相反する外側に向けて折曲されている。一対の軸部51は、一対のアーム部50に対して例えば略直角折曲されている。なお、一対の軸部51は、一対のアーム部50に対して鈍角に折曲されていてもよい。 The pair of shaft portions 51 are bent toward the opposite outer sides from the ends of the pair of arm portions 50. The pair of shaft portions 51 are bent at a substantially right angle to the pair of arm portions 50, for example. The pair of shaft portions 51 may be bent at an obtuse angle with respect to the pair of arm portions 50.

また、図3ないし図5に示すように、軸受部材45は、1枚の金属板を曲げ加工して一体に形成されている。軸受部材45は、ベースプレート25に取り付けられる取付部54、この取付部54から立ち上げられた立上げ部55、この立上げ部55の幅方向の両側部から取付部54に対向するように折曲された一対の支持部56、およびこれら一対の支持部56の先端に設けられた一対の軸受部57を有している。一対の軸受部57は、支持部56の先端部が筒状に湾曲されることによって形成されている。一対の軸受部57の相対する内端側から線ばね44の一対の軸部51が挿入されている。一対の軸受部57により、線ばね44の一対の軸部51を回転可能に軸受している。 Further, as shown in FIGS. 3 to 5, the bearing member 45 is integrally formed by bending one metal plate. The bearing member 45 is bent so as to face the mounting portion 54 mounted on the base plate 25, the rising portion 55 raised from the mounting portion 54, and both side portions in the width direction of the rising portion 55 in the width direction. It has a pair of support portions 56 and a pair of bearing portions 57 provided at the tips of the pair of support portions 56. The pair of bearing portions 57 is formed by bending the tip portion of the support portion 56 into a cylindrical shape. A pair of shaft portions 51 of wire springs 44 are inserted from the opposite inner end sides of the pair of bearing portions 57. The pair of bearing portions 57 rotatably bears the pair of shaft portions 51 of the wire spring 44.

一対の軸受部57の軸心aは、一対の軸受部57の相対する端部間を結ぶ仮想中心軸bに対して同一方向に対称的に傾いている。一対の軸受部57の軸心aが傾く方向は、線ばね44の一対のアーム部50が光源ユニット12の上面に平行となる基準位置P0を0°とした場合の角度βが90°以上であって、好ましくは90~120°の範囲の方向である。本実施形態では、一対の軸受部57の軸心aが傾く方向は、例えば角度βが120°となる方向とする。また、一対の軸受部57の軸心aが仮想中心軸bに対して傾く角度αは、10°前後が好ましい。 The axial center a of the pair of bearing portions 57 is inclined symmetrically in the same direction with respect to the virtual central axis b connecting the opposing ends of the pair of bearing portions 57. The direction in which the axis a of the pair of bearing portions 57 is tilted is when the angle β is 90 ° or more when the reference position P0 at which the pair of arm portions 50 of the wire spring 44 are parallel to the upper surface of the light source unit 12 is 0 °. The direction is preferably in the range of 90 to 120 °. In the present embodiment, the direction in which the axis a of the pair of bearing portions 57 is tilted is, for example, the direction in which the angle β is 120 °. Further, the angle α at which the axis a of the pair of bearing portions 57 is tilted with respect to the virtual center axis b is preferably around 10 °.

そして、図4および図5(中立位置P3の線ばね44および軸受部材45を図4矢視Aから見た正面図)に示すように、軸受部材45に軸受された線ばね44は、仮想中心軸bを中心として回転可能とする。従って、仮想中心軸bは、線ばね44が回転する回転軸である。さらに、軸受部材45に軸受された線ばね44は、仮想中心軸bの軸方向から見て一対の軸受部57の軸心aと線ばね44の一対のアーム部50とが重なる中立位置P3において、一対のアーム部50の間隔が変化するように最も弾性変形した状態にある。すなわち、線ばね44自体は、一対の軸部51が一対のアーム部50に対して例えば直角または鈍角に折曲されているのに対して、軸受部材45の一対の軸受部57により一対の軸部51が角度αずつ同一方向に対称的に傾けられることにより、一対のアーム部50の間隔が狭まるように線ばね44の全体が最も弾性変形した状態にある。 Then, as shown in FIGS. 4 and 5 (front view of the wire spring 44 at the neutral position P3 and the bearing member 45 as viewed from arrow A in FIG. 4), the wire spring 44 bearing on the bearing member 45 has a virtual center. It is rotatable around the axis b. Therefore, the virtual center axis b is a rotation axis on which the wire spring 44 rotates. Further, the wire spring 44 bearing on the bearing member 45 is at the neutral position P3 where the axial center a of the pair of bearing portions 57 and the pair of arm portions 50 of the wire spring 44 overlap when viewed from the axial direction of the virtual central axis b. , It is in the most elastically deformed state so that the distance between the pair of arm portions 50 changes. That is, in the wire spring 44 itself, the pair of shaft portions 51 are bent at a right angle or an obtuse angle with respect to the pair of arm portions 50, whereas the pair of shaft portions 57 of the bearing member 45 form a pair of shafts. Since the portions 51 are tilted symmetrically in the same direction by an angle α, the entire wire spring 44 is in the most elastically deformed state so that the distance between the pair of arm portions 50 is narrowed.

そのため、線ばね44は、仮想中心軸bの軸方向から見て一対の軸受部57の軸心aと線ばね44の一対のアーム部50とが重なる中立位置P3を境として、弾性変形の反発力により回転方向の一方であって光源ユニット12の外側に開く展開回転方向F1と、回転方向の他方であって光源ユニット12の内側に折り畳まれる折畳回転方向F2とのそれぞれに向けて回転力が生じる。すなわち、一対の軸受部57によって線ばね44の一対の軸部51が仮想中心軸bに対して傾けられる角度は、一対のアーム部50が中立位置P3に位置するときが最も大きく、一対のアーム部50が中立位置P3よりも展開回転方向F1または折畳回転方向F2に向かって回転するのに従って小さくなっていき、中立位置P3に対して90°方向が最も小さくなる。そのため、一対のアーム部50が中立位置P3よりも展開回転方向F1または折畳回転方向F2に少しでも回転操作すると、線ばね44の弾性変形に対して元に戻ろうとする反発力である弾性力により、展開回転方向F1または折畳回転方向F2に向けて回転力が生じる。なお、線ばね44の一対の軸部51が一対のアーム部50に対して鈍角に折曲されていている場合には、線ばね44の弾性変形が大きくなるため、より強い回転力が生じる。 Therefore, the wire spring 44 repels elastic deformation at the neutral position P3 where the axis a of the pair of bearing portions 57 and the pair of arm portions 50 of the wire spring 44 overlap when viewed from the axial direction of the virtual center axis b. Rotational force toward each of the unfolding rotational direction F1 which is one of the rotational directions and opens to the outside of the light source unit 12 by the force, and the folding rotational direction F2 which is the other of the rotational directions and is folded inside the light source unit 12. Occurs. That is, the angle at which the pair of shaft portions 51 of the wire spring 44 are tilted by the pair of bearing portions 57 with respect to the virtual center axis b is the largest when the pair of arm portions 50 are located at the neutral position P3, and the pair of arms. The portion 50 becomes smaller as it rotates from the neutral position P3 toward the unfolding rotation direction F1 or the folding rotation direction F2, and becomes smaller in the 90 ° direction with respect to the neutral position P3. Therefore, if the pair of arm portions 50 are rotated in the unfolding rotation direction F1 or the folding rotation direction F2 from the neutral position P3 even a little, the elastic force is a repulsive force that tries to return to the original elastic deformation of the wire spring 44. As a result, a rotational force is generated in the unfolding rotation direction F1 or the folding rotation direction F2. When the pair of shaft portions 51 of the wire spring 44 are bent at an obtuse angle with respect to the pair of arm portions 50, the elastic deformation of the wire spring 44 becomes large, so that a stronger rotational force is generated.

また、図3および図7に示すように、押え部材46は、一方向である折畳回転方向F2に向けて回転する線ばね44の一対のアーム部50が接触し、線ばね44が所定の回転位置(押え方向切換位置P1)に回転するまでは一対のアーム部50の間隔が広がるように線ばね44を弾性変形させ、線ばね44が所定の回転位置(押え方向切換位置P1)を越えて一方向である折畳回転方向F2に回転した状態では一対のアーム部50の間隔が狭まる弾性力により線ばね44を一方向である折畳回転方向F2に向けて回転させるように押えるものである。 Further, as shown in FIGS. 3 and 7, the pressing member 46 is in contact with the pair of arm portions 50 of the wire spring 44 rotating in the folding rotation direction F2, which is one direction, and the wire spring 44 is predetermined. The wire spring 44 is elastically deformed so that the distance between the pair of arm portions 50 is widened until it rotates to the rotation position (pressing direction switching position P1), and the wire spring 44 exceeds the predetermined rotation position (pressing direction switching position P1). When rotated in the unidirectional folding rotation direction F2, the elastic force that narrows the distance between the pair of arm portions 50 presses the wire spring 44 so as to rotate it toward the unidirectional folding rotation direction F2. be.

押え部材46は、1枚の板ばねを曲げ加工して一体に形成されている。板ばねとしては、例えばステンレス板が用いられる。押え部材46は、取付部60、およびこの取付部60の両側部から折曲され線ばね44の一対のアーム部50が接触する一対の押え部61を有する。 The pressing member 46 is integrally formed by bending one leaf spring. As the leaf spring, for example, a stainless steel plate is used. The presser member 46 has a mounting portion 60 and a pair of presser portions 61 that are bent from both sides of the mounting portion 60 and come into contact with the pair of arm portions 50 of the wire spring 44.

取付部60は、この取付部60上に軸受部材45の取付部54が重ね合わされ、ベースプレート25に対して取付部54と一体にねじ止め固定される。すなわち、押え部材46は、軸受部材45と同一部材である光源ユニット12に設置される。 In the mounting portion 60, the mounting portion 54 of the bearing member 45 is superposed on the mounting portion 60, and is screwed and fixed to the base plate 25 integrally with the mounting portion 54. That is, the pressing member 46 is installed in the light source unit 12, which is the same member as the bearing member 45.

一対の押え部61は、取付部60の両側部から互いに間隔が狭まるように内側に向けて折曲された立上げ部62、およびこの立上げ部62の上部から互いに間隔が広がるように外側に向けて折曲されたガイド部63を有している。 The pair of holding portions 61 are bent inward from both sides of the mounting portion 60 so as to be narrowly spaced from each other, and outward so as to be spaced apart from each other from the upper portion of the rising portion 62. It has a guide portion 63 that is bent toward it.

一対の押え部61(ガイド部63)は、一方向である折畳回転方向F2に回転する線ばね44の一対のアーム部50が所定の回転位置(押え方向切換位置P1)に回転するまでは一対のアーム部50の間隔が広がるようにガイドする拡開ガイド部64、および一方向である折畳回転方向F2に回転する線ばね44の一対のアーム部50が所定の回転位置(押え方向切換位置P1)を越えてからは一対のアーム部50の間隔が狭まるようにガイドする押えガイド部65を有する。拡開ガイド部64と押えガイド部65との間には、一対のアーム部50の間隔が広がるようにガイドするのと一対のアーム部50の間隔が狭まるようにガイドするのとが切り換わる切換り部66が設けられている。この切換り部66の位置は、一方向である折畳回転方向F2に回転する線ばね44の一対のアーム部50の所定の回転位置(押え方向切換位置P1)に対応している。一対の押え部61の拡開ガイド部64間および押えガイド部65間の幅は、一対のアーム部50間の幅よりも広く設けられている。 The pair of holding portions 61 (guide portion 63) is provided until the pair of arm portions 50 of the wire springs 44 rotating in the folding rotation direction F2, which is one direction, rotate to a predetermined rotation position (pressing direction switching position P1). The expansion guide portion 64 that guides the pair of arm portions 50 so that the distance between them is widened, and the pair of arm portions 50 of the wire spring 44 that rotates in the folding rotation direction F2, which is one direction, are in a predetermined rotation position (pressing direction switching). After the position P1) is exceeded, it has a presser guide portion 65 that guides the pair of arm portions 50 so that the distance between them is narrowed. Switching between the expansion guide portion 64 and the presser guide portion 65 to switch between guiding so that the distance between the pair of arm portions 50 is widened and guiding so that the distance between the pair of arm portions 50 is narrowed. A beam 66 is provided. The position of the switching portion 66 corresponds to a predetermined rotation position (pressing direction switching position P1) of the pair of arm portions 50 of the wire spring 44 rotating in the folding rotation direction F2 which is one direction. The width between the expansion guide portions 64 and the presser guide portions 65 of the pair of presser portions 61 is wider than the width between the pair of arm portions 50.

そして、線ばね44の一対のアーム部50が押え部材46の一対の押え部61の拡開ガイド部64に接触した状態で、線ばね44を折畳回転方向F2に回転させていくと、一対のアーム部50の間隔が広がるように線ばね44が弾性変形するとともに、一対の押え部61の間隔が狭まるように押え部材46が弾性変形する。さらに、折畳回転方向F2に回転させていく線ばね44の一対のアーム部50が所定の回転位置(押え方向切換位置P1)つまり切換り部66を越えて、押え部材46の一対の押え部61の押えガイド部65に接触すると、線ばね44および押え部材46のそれぞれの弾性変形に対する反発力である弾性力により、線ばね44の一対のアーム部50が押え部材46の一対の押え部61の押えガイド部65に沿って折畳回転方向F2に移動し、線ばね44が折畳回転方向F2に回転する回転付勢力が生じる。 Then, when the pair of arm portions 50 of the wire spring 44 are in contact with the expansion guide portion 64 of the pair of pressing portions 61 of the pressing member 46, the wire spring 44 is rotated in the folding rotation direction F2, and the pair is formed. The wire spring 44 is elastically deformed so that the distance between the arm portions 50 is widened, and the presser member 46 is elastically deformed so that the distance between the pair of pressing portions 61 is narrowed. Further, the pair of arm portions 50 of the wire springs 44 that rotate in the folding rotation direction F2 exceed the predetermined rotation position (pressing direction switching position P1), that is, the switching portion 66, and the pair of pressing portions of the pressing member 46. When the presser guide portion 65 of the wire spring 44 is contacted, the pair of arm portions 50 of the wire spring 44 are brought into contact with the pair of presser portions 61 of the presser member 46 due to the elastic force which is the repulsive force against the elastic deformation of the wire spring 44 and the presser member 46. It moves in the folding rotation direction F2 along the presser foot guide portion 65, and a rotational urging force is generated in which the wire spring 44 rotates in the folding rotation direction F2.

ここで、図4を参照して、線ばね44の動きをまとめる。線ばね44は、中立位置P3を境として、線ばね44の弾性変形の反発力により、光源ユニット12の外側に開く展開回転方向F1に向けた回転力A1と、光源ユニット12の内側に折り畳まれる折畳回転方向F2に向けた回転力A2とが生じる。線ばね44は、展開回転方向F1に生じる回転力A1により、中立位置P3からベースプレート25の周辺部に当接する展開自立位置P4に回転して保持される。線ばね44は、折畳回転方向F2に生じる回転力A2により、中立位置P3から押え部材46の拡開ガイド64に当接する折畳自立位置P2に回転して保持される。この線ばね44に生じる展開回転方向F1および折畳回転方向F2の回転力A1、A2は、比較的弱く、線ばね44の自立状態が保てる程度で、例えば光源ユニット12の自重が加われば自立状態が解除される。 Here, the movement of the wire spring 44 is summarized with reference to FIG. The wire spring 44 is folded inside the light source unit 12 and the rotational force A1 toward the development rotation direction F1 that opens to the outside of the light source unit 12 due to the repulsive force of the elastic deformation of the wire spring 44 with the neutral position P3 as the boundary. A rotational force A2 is generated in the folding rotation direction F2. The wire spring 44 is rotated and held from the neutral position P3 to the unfolded self-supporting position P4 that abuts on the peripheral portion of the base plate 25 by the rotational force A1 generated in the unfolded rotation direction F1. The wire spring 44 is rotated and held from the neutral position P3 to the folding independent position P2 abutting on the expansion guide 64 of the pressing member 46 by the rotational force A2 generated in the folding rotation direction F2. The rotational forces A1 and A2 in the unfolding rotation direction F1 and the folding rotation direction F2 generated in the wire spring 44 are relatively weak, and the self-supporting state of the wire spring 44 can be maintained. Is released.

さらに、線ばね44は、押え方向切換位置P1を境として、線ばね44の弾性変形の反発力および押え部材46の弾性変形の反発力と拡開ガイド部64および押えガイド部65の傾斜によるガイド作用とにより、押え方向切換位置P1と折畳自立位置P2との間において展開回転方向F1に向けて回転力B1が生じ、押え方向切換位置P1と最大押え位置P5との間において折畳回転方向F2に向けて回転力B2が生じる。この線ばね44に生じる折畳回転方向F2の回転力B2は、比較的強く、光源ユニット12の自重を支えることが可能な強さである。なお、回転力A1、A2と回転力B1、B2の強さは、A1、A2<B1、B2の関係にある。 Further, the wire spring 44 is guided by the repulsive force of the elastic deformation of the wire spring 44 and the repulsive force of the elastic deformation of the pressing member 46 and the inclination of the expansion guide portion 64 and the pressing guide portion 65 with the pressing direction switching position P1 as a boundary. Due to the action, a rotational force B1 is generated in the unfolding rotation direction F1 between the pressing direction switching position P1 and the folding independent position P2, and the folding rotation direction is generated between the pressing direction switching position P1 and the maximum pressing position P5. A rotational force B2 is generated toward F2. The rotational force B2 in the folding rotation direction F2 generated in the wire spring 44 is relatively strong and is strong enough to support the weight of the light source unit 12. The strengths of the rotational forces A1 and A2 and the rotational forces B1 and B2 are in the relationship of A1, A2 <B1 and B2.

また、図3および図8に示すように、取付装置13のばね受41は、1枚の金属板を曲げ加工して一体に形成されている。ばね受41は、取付板部70、この取付板部70の一辺から折曲されたガイド板部71、このガイド板部71から折曲された受板部72、および取付板部70の他辺から折曲されたカバー部73を備えている。さらに、ばね受41は、ガイド板部71に設けられる開口部74および引掛部75を有している。 Further, as shown in FIGS. 3 and 8, the spring receiver 41 of the mounting device 13 is integrally formed by bending one metal plate. The spring receiver 41 includes a mounting plate 70, a guide plate 71 bent from one side of the mounting plate 70, a receiving plate 72 bent from the guide plate 71, and the other side of the mounting plate 70. It has a cover portion 73 bent from. Further, the spring receiver 41 has an opening 74 and a hooking portion 75 provided in the guide plate portion 71.

取付板部70は、器具本体11の下面にねじ止めによって取り付けられる。 The mounting plate portion 70 is attached to the lower surface of the instrument main body 11 by screwing.

ガイド板部71は、取付板部70から下方へ向けて折曲されている。ガイド板部71には、線ばね44のフック部49および一対のアーム部50が挿通される開口部74が形成されている。 The guide plate portion 71 is bent downward from the mounting plate portion 70. The guide plate portion 71 is formed with an opening 74 through which the hook portion 49 of the wire spring 44 and the pair of arm portions 50 are inserted.

受板部72は、ガイド板部71の下端からガイド板部71の外側方へ向けて斜めに突設されている。 The receiving plate portion 72 projects diagonally from the lower end of the guide plate portion 71 toward the outside of the guide plate portion 71.

カバー部73は、取付板部70から下方へ向けて折曲された後面カバー部76、およびこの後面カバー部76の両側から取付板部70の両側下方に配置されるように折曲された側面カバー部77を有している。そして、カバー部73により、ガイド板部71とともに取付板部70の下方域の周囲を囲み、例えば器具本体11と光源ユニット12との間に配置されるコネクタ付ケーブルなどが入り込まないようにしている。 The cover portion 73 is a rear cover portion 76 that is bent downward from the mounting plate portion 70, and side surfaces that are bent so as to be arranged below both sides of the mounting plate portion 70 from both sides of the rear cover portion 76. It has a cover portion 77. The cover portion 73 surrounds the lower region of the mounting plate portion 70 together with the guide plate portion 71 so that, for example, a cable with a connector arranged between the instrument main body 11 and the light source unit 12 does not enter. ..

開口部74は、ガイド板部71から取付板部70の一部に亘って連続して開口形成されている。ガイド板部71に形成された開口部74の幅方向の幅は、開口部74の引掛部75が設けられた縁部側である開口部74の下部側が線ばね44の一対のアーム部50間の幅よりも広く、引掛部75が設けられた開口部74の縁部側から反対側の縁部側である開口部74の上部側に向かうに従って狭くなるように略台形状に形成されている。開口部74の上部側の幅は、線ばね44の一対のアーム部50間の幅を幅方向に規制可能とし、例えば一対のアーム部50間の幅と同程度に形成されている。 The opening 74 is continuously formed from the guide plate portion 71 to a part of the mounting plate portion 70. The width of the opening 74 formed in the guide plate portion 71 in the width direction is such that the lower side of the opening 74, which is the edge side where the hook portion 75 of the opening 74 is provided, is between the pair of arm portions 50 of the wire spring 44. It is formed in a substantially trapezoidal shape so as to be wider than the width of the opening 75 and narrowed from the edge side of the opening 74 provided with the hooking portion 75 toward the upper side of the opening 74 which is the opposite edge side. .. The width of the upper portion of the opening 74 allows the width between the pair of arm portions 50 of the wire spring 44 to be regulated in the width direction, and is formed to be about the same as the width between the pair of arm portions 50, for example.

引掛部75は、ガイド板部71から開口部74に突設され、線ばね44のフック部49を引っ掛け可能とする。引掛部75は、開口部74の取付板部70から離れた縁部である開口部74の下側縁部で開口部74の幅方向の中央に設けられている。引掛部75は、先端側がガイド板部71の内面側に突出するように断面略L字形に形成されている。 The hook portion 75 is projected from the guide plate portion 71 to the opening 74 so that the hook portion 49 of the wire spring 44 can be hooked. The hook portion 75 is provided at the lower edge portion of the opening 74, which is an edge portion of the opening 74 away from the mounting plate portion 70, at the center in the width direction of the opening 74. The hook portion 75 is formed in a substantially L-shaped cross section so that the tip end side projects toward the inner surface side of the guide plate portion 71.

次に、照明装置10の動作を説明する。 Next, the operation of the lighting device 10 will be described.

図9には、光源ユニット12の線ばね44が中立位置P3にある状態を示す。 FIG. 9 shows a state in which the wire spring 44 of the light source unit 12 is in the neutral position P3.

そして、線ばね44の一対のアーム部50を中立位置P3から展開回転方向F1に少し回転操作すると、上述したように、線ばね44の弾性力により、展開回転方向F1に向けて回転力A1が生じる。そのため、図10に示すように、線ばね44が展開回転方向F1に回転し、フック部49および一対のアーム部50の先端側が光源ユニット12の外側方に突出するように展開した展開自立位置P4に保持される。 Then, when the pair of arm portions 50 of the wire spring 44 are slightly rotated from the neutral position P3 to the unfolding rotation direction F1, as described above, the elastic force of the wire spring 44 causes the rotational force A1 to be generated in the unfolding rotation direction F1. Occurs. Therefore, as shown in FIG. 10, the wire spring 44 rotates in the unfolding rotation direction F1, and the unfolding self-standing position P4 expanded so that the tip side of the hook portion 49 and the pair of arm portions 50 protrudes outward of the light source unit 12. Is held in.

一方、線ばね44の一対のアーム部50を中立位置P3から折畳回転方向F2に少し回転操作すると、上述したように、線ばね44の弾性力により、折畳回転方向F2に向けて回転力A2が生じる。そのため、図11に示すように、線ばね44が折畳回転方向F2に回転し、フック部49および一対のアーム部50が光源ユニット12の内側に向けて傾き、一対のアーム部50が押え部材46の一対の押え部61(拡開ガイド部64)に接触した折畳自立位置P2に保持される。 On the other hand, when the pair of arm portions 50 of the wire spring 44 is slightly rotated from the neutral position P3 in the folding rotation direction F2, as described above, the elastic force of the wire spring 44 causes the rotational force toward the folding rotation direction F2. A2 occurs. Therefore, as shown in FIG. 11, the wire spring 44 rotates in the folding rotation direction F2, the hook portion 49 and the pair of arm portions 50 are tilted toward the inside of the light source unit 12, and the pair of arm portions 50 are pressing members. It is held in the folding independent position P2 in contact with the pair of 46 holding portions 61 (expansion guide portion 64).

また、図12には、光源ユニット12の線ばね44が装着位置(押え方向切換位置P1と最大押え位置P5との間)にある状態を示す。線ばね44は、光源ユニット12上に折り畳まれ、一対のアーム部50が押え部材46の一対の押え部61(押えガイド部65)に接触する。この状態で、上述したように、線ばね44および押え部材46の弾性力により、線ばね44には折畳回転方向F2に向けて回転力B2が生じる。 Further, FIG. 12 shows a state in which the wire spring 44 of the light source unit 12 is in the mounting position (between the pressing direction switching position P1 and the maximum pressing position P5). The wire spring 44 is folded on the light source unit 12, and the pair of arm portions 50 come into contact with the pair of pressing portions 61 (pressing guide portion 65) of the pressing member 46. In this state, as described above, the elastic force of the wire spring 44 and the pressing member 46 causes the wire spring 44 to generate a rotational force B2 in the folding rotation direction F2.

そして、設置面に設置された器具本体11に対する光源ユニット12の装着手順を説明する。 Then, the procedure for mounting the light source unit 12 on the fixture main body 11 installed on the installation surface will be described.

図13に示すように、光源ユニット12の一側の線ばね44を光源ユニット12の外側方に突出する展開自立位置P4に回転した状態とする。展開自立位置P4の線ばね44は、回転操作しない限り、光源ユニット12を傾けたり回転させなるなどしても、展開自立位置P4に保持されている。なお、光源ユニット12の他側の線ばね44は、展開自立位置P4に回転した状態、折畳自立位置P2に回転した状態のいずれにあってもよい。 As shown in FIG. 13, the wire spring 44 on one side of the light source unit 12 is rotated to the unfolding independent position P4 protruding outward from the light source unit 12. The wire spring 44 of the unfolded self-supporting position P4 is held at the unfolded self-supporting position P4 even if the light source unit 12 is tilted or rotated unless it is rotated. The wire spring 44 on the other side of the light source unit 12 may be in either a state of being rotated to the unfolding independent position P4 or a state of being rotated to the folding independent position P2.

光源ユニット12の一側を上方に向け、光源ユニット12の一側に配置されている線ばね44のフック部49および一対のアーム部50の先端側を器具本体11のばね受41の開口部74に挿入し、フック部49を引掛部75に引っ掛ける。このとき、線ばね44は展開自立位置P4に保持されているため、線ばね44を展開状態に手で押えるなどの操作が必要なく、作業性を向上できる。 With one side of the light source unit 12 facing upward, the hook portion 49 of the wire spring 44 arranged on one side of the light source unit 12 and the tip end side of the pair of arm portions 50 are the openings 74 of the spring receiver 41 of the instrument body 11. And hook the hook part 49 to the hook part 75. At this time, since the wire spring 44 is held in the unfolded self-standing position P4, it is not necessary to manually press the wire spring 44 in the unfolded state, and workability can be improved.

このとき、図14に示すように、ばね受41の開口部74は下部側の幅が一対のアーム部50間の幅よりも広いため、フック部49および一対のアーム部50の先端側を器具本体11のばね受41の開口部74に挿入しやすいとともに、フック部49を引掛部75に引っ掛けやすく、操作性がよい。 At this time, as shown in FIG. 14, since the width of the lower portion of the opening 74 of the spring receiver 41 is wider than the width between the pair of arm portions 50, the tip side of the hook portion 49 and the pair of arm portions 50 is used as an instrument. It is easy to insert it into the opening 74 of the spring receiver 41 of the main body 11, and it is easy to hook the hook portion 49 to the hook portion 75, so that the operability is good.

線ばね44のフック部49をばね受41の引掛部75に引っ掛けた状態で、器具本体11に対して光源ユニット12が片側吊下げ状態となる。この片側吊下げ状態で、電源ユニット21からのコネクタ付ケーブルと光源ユニットからのコネクタ付ケーブルとをコネクタ接続する。 With the hook portion 49 of the wire spring 44 hooked on the hook portion 75 of the spring receiver 41, the light source unit 12 is suspended on one side with respect to the instrument main body 11. In this one-sided suspension state, the cable with a connector from the power supply unit 21 and the cable with a connector from the light source unit are connected by a connector.

図15に示すように、光源ユニット12の他側を上方に移動させ、光源ユニット12の他側に配置されている線ばね44のフック部49および一対のアーム部50の先端側をばね受41の開口部74に挿入し、フック部49を引掛部75に引っ掛ける。このときも、ばね受41の開口部74の形状により、フック部49および一対のアーム部50の先端側を器具本体11のばね受41の開口部74に挿入しやすいとともに、フック部49を引掛部75に引っ掛けやすく、操作性がよい。さらに、線ばね44のフック部49をばね受41の開口部74に導く際、線ばね44を折畳自立位置P2に回転させておくことにより、フック部49がばね受41の開口部74に入りやすく、作業性がよい。 As shown in FIG. 15, the other side of the light source unit 12 is moved upward, and the hook portion 49 of the wire spring 44 and the tip end side of the pair of arm portions 50 arranged on the other side of the light source unit 12 are connected to the spring receiver 41. Insert into the opening 74 of the hook and hook the hook 49 to the hook 75. Also at this time, the shape of the opening 74 of the spring receiver 41 makes it easy to insert the tip side of the hook portion 49 and the pair of arm portions 50 into the opening 74 of the spring receiver 41 of the instrument main body 11, and the hook portion 49 is hooked. It is easy to hook on the part 75 and has good operability. Further, when the hook portion 49 of the wire spring 44 is guided to the opening 74 of the spring receiver 41, the hook portion 49 becomes the opening 74 of the spring receiver 41 by rotating the wire spring 44 to the folding independent position P2. Easy to enter and easy to work with.

光源ユニット12の他側を上方に移動させていったときに、光源ユニット12の一側の線ばね44が中立位置P3を越え、折畳回転方向F2に向けて回転力A2が生じる。そのため、この線ばね44の回転力A2が、器具本体11に対して光源ユニット12の一側を適正位置に移行させるように作用し、光源ユニット12の他側の線ばね44をばね受41に装着しやすくできる。 When the other side of the light source unit 12 is moved upward, the wire spring 44 on one side of the light source unit 12 exceeds the neutral position P3, and a rotational force A2 is generated in the folding rotation direction F2. Therefore, the rotational force A2 of the wire spring 44 acts on the fixture body 11 so as to shift one side of the light source unit 12 to an appropriate position, and the wire spring 44 on the other side of the light source unit 12 acts as a spring receiver 41. Easy to install.

そして、光源ユニット12の他側の線ばね44のフック部49をばね受41の引掛部75に引っ掛けることにより、光源ユニット12は器具本体11に対して両側吊下げ状態となる。この状態では、光源ユニット12の一側の線ばね44と他側の線ばね44とのバランスがとれ、光源ユニット12は器具本体11と平行な位置の中央に自動的に位置される。このとき、光源ユニット12の一側の線ばね44および他側の線ばね44にはそれぞればね受41に引っ掛かる方向に回転力A2が生じているため、線ばね44を持って持ち上げながらフック部49をばね受41の引掛部75から外さない限り、線ばね44はばね受41から外れないため、光源ユニット12が不用意に脱落することがない。 Then, by hooking the hook portion 49 of the wire spring 44 on the other side of the light source unit 12 to the hook portion 75 of the spring receiver 41, the light source unit 12 is suspended on both sides with respect to the instrument main body 11. In this state, the wire spring 44 on one side of the light source unit 12 and the wire spring 44 on the other side are balanced, and the light source unit 12 is automatically positioned at the center of the position parallel to the instrument main body 11. At this time, since the rotational force A2 is generated in the wire spring 44 on one side and the wire spring 44 on the other side of the light source unit 12 in the direction of being hooked on the spring receiver 41, the hook portion 49 is lifted while holding the wire spring 44. The wire spring 44 does not come off from the spring receiver 41 unless is removed from the hook portion 75 of the spring receiver 41, so that the light source unit 12 does not accidentally fall off.

その後、光源ユニット12を押上げ操作して器具本体11に装着する。このとき、光源ユニット12を一側および他側を平行に押上げ操作して器具本体11に装着してもよいし、光源ユニット12の一側または他側を片側ずつ順に押上げ操作して器具本体11に装着してもよい。 After that, the light source unit 12 is pushed up and attached to the instrument main body 11. At this time, the light source unit 12 may be mounted on the instrument main body 11 by pushing up one side and the other side in parallel, or by pushing up one side or the other side of the light source unit 12 one side at a time in order. It may be attached to the main body 11.

図16には、光源ユニット12の他側を押上げ操作した光源ユニット12の片側押上げ状態を示す。そして、光源ユニット12の一側の押上げ操作時の動作について図16ないし図19にて説明する。 FIG. 16 shows a one-sided push-up state of the light source unit 12 in which the other side of the light source unit 12 is pushed up. Then, the operation at the time of the push-up operation on one side of the light source unit 12 will be described with reference to FIGS. 16 to 19.

図16に示すように、光源ユニット12の一側に配置されている線ばね44のフック部49がばね受41の引掛部75に引っ掛けられ、この線ばね44で光源ユニット12の一側が器具本体11に吊り下げられた状態にある。このとき、線ばね44の一対のアーム部50は押え部材46の一対の押え部61(拡開ガイド部64)に接触していない。 As shown in FIG. 16, the hook portion 49 of the wire spring 44 arranged on one side of the light source unit 12 is hooked on the hook portion 75 of the spring receiver 41, and one side of the light source unit 12 is the instrument main body by this wire spring 44. It is suspended at 11. At this time, the pair of arm portions 50 of the wire spring 44 are not in contact with the pair of pressing portions 61 (expansion guide portion 64) of the pressing member 46.

光源ユニット12の一側を押し上げていくと、線ばね44の回転力A2によって線ばね44が折畳回転方向F2に回転していく。光源ユニット12の一側を押し上げていく途中で、線ばね44の一対のアーム部50が押え部材46の一対の押え部61(拡開ガイド部64)に接触し、線ばね44の折畳回転方向F2への回転が折畳自立位置P2で一旦止まり、その後は、線ばね44が光源ユニット12の一側とともに押し上げられる。 When one side of the light source unit 12 is pushed up, the wire spring 44 rotates in the folding rotation direction F2 due to the rotational force A2 of the wire spring 44. While pushing up one side of the light source unit 12, the pair of arm portions 50 of the wire spring 44 come into contact with the pair of pressing portions 61 (expansion guide portion 64) of the pressing member 46, and the folding rotation of the wire spring 44 The rotation in the direction F2 stops once at the folding self-standing position P2, after which the wire spring 44 is pushed up together with one side of the light source unit 12.

図17に示すように、光源ユニット12の一側とともに押し上げられる線ばね44の一対のアーム部50のアームガイド部50aがばね受41の取付板部70の下面に接触し、アームガイド部50aの上昇が規制される。そのため、光源ユニット12の一側をさらに押し上げていくと、線ばね44を折畳回転方向F2に強制的に回転させていくことになる。これにより、凸円弧状のアームガイド部50aがばね受41の取付板部70の下面を摺動しながらばね受41の開口部74に挿通されていく。このように、線ばね44が折畳回転方向F2に回転しながらばね受41側に移動してくことにより、一対のアーム部50のアーム当接部50dがばね受41の受板部72の上方域に移動していく。 As shown in FIG. 17, the arm guide portion 50a of the pair of arm portions 50 of the wire spring 44 pushed up together with one side of the light source unit 12 comes into contact with the lower surface of the mounting plate portion 70 of the spring receiver 41, and the arm guide portion 50a The rise is regulated. Therefore, when one side of the light source unit 12 is pushed up further, the wire spring 44 is forcibly rotated in the folding rotation direction F2. As a result, the convex arc-shaped arm guide portion 50a is inserted into the opening 74 of the spring receiver 41 while sliding on the lower surface of the mounting plate portion 70 of the spring receiver 41. In this way, the wire spring 44 moves toward the spring receiver 41 while rotating in the folding rotation direction F2, so that the arm contact portion 50d of the pair of arm portions 50 is above the receiving plate portion 72 of the spring receiver 41. Move to the area.

このとき、図18に示すように、一対のアーム部50が開口部74の上部側の幅狭領域に移動し、開口部74の両側縁で一対のアーム50の幅方向の位置が規制される。これにより、線ばね44を介して、器具本体11に対して押し上げていく光源ユニット12の位置を位置決めし、器具本体11に対して光源ユニット12を正しく組み合わせて装着できるようにする。 At this time, as shown in FIG. 18, the pair of arm portions 50 move to the narrow region on the upper side of the opening 74, and the positions of the pair of arms 50 in the width direction are restricted by both side edges of the opening 74. .. As a result, the position of the light source unit 12 that pushes up with respect to the fixture main body 11 is positioned via the wire spring 44, and the light source unit 12 can be correctly combined and mounted on the fixture main body 11.

さらに、線ばね44の一対のアーム部50が押え部材46の一対の押え部61の拡開ガイド部64に接触した状態で、光源ユニット12の一側をさらに押し上げ、線ばね44を折畳回転方向F2に回転させていくと、一対のアーム部50の間隔が広がるように線ばね44が弾性変形するとともに、一対の押え部61の間隔が狭まるように押え部材46が弾性変形する。 Further, in a state where the pair of arm portions 50 of the wire spring 44 are in contact with the expansion guide portion 64 of the pair of pressing portions 61 of the pressing member 46, one side of the light source unit 12 is further pushed up, and the wire spring 44 is folded and rotated. When rotated in the direction F2, the wire spring 44 is elastically deformed so that the distance between the pair of arm portions 50 is widened, and the presser member 46 is elastically deformed so that the distance between the pair of holding portions 61 is narrowed.

そして、光源ユニット12の一側をさらに押し上げていくと、折畳回転方向F2に回転させていく線ばね44の一対のアーム部50が所定の回転位置(押え方向切換位置P1)つまり切換り部66を越えて、押え部材46の一対の押え部61の押えガイド部65に接触する。これにより、線ばね44および押え部材46のそれぞれの弾性変形に対する反発力である弾性力により、線ばね44の一対のアーム部50が押え部材46の一対の押え部61の押えガイド部65に沿って折畳回転方向F2に回転するように、線ばね44に折畳回転方向F2に回転する回転力B2が生じる。 Then, when one side of the light source unit 12 is further pushed up, the pair of arm portions 50 of the wire springs 44 that rotate in the folding rotation direction F2 are in a predetermined rotation position (pressing direction switching position P1), that is, a switching portion. Beyond 66, it comes into contact with the presser guide portion 65 of the pair of presser portions 61 of the presser member 46. As a result, due to the elastic force that is the repulsive force against the elastic deformation of the wire spring 44 and the presser member 46, the pair of arm portions 50 of the wire spring 44 are along the presser guide portion 65 of the pair of presser portions 61 of the presser member 46. A rotational force B2 that rotates in the folding rotation direction F2 is generated in the wire spring 44 so that the wire spring 44 rotates in the folding rotation direction F2.

そのため、図19に示すように、線ばね44に作用する回転付勢力により、線ばね44が折畳回転方向F2に回転し、ばね受41の受板部72の上方域に既に移動していた一対のアーム部50のアーム当接部50dがばね受41の受板部72の上面側に当接し、アーム当接部50dと受板部72との接触箇所を支点として光源ユニット12の一側が器具本体11に向けて上方に引き上げられる。これにより、器具本体11に光源ユニット12の一側が装着され、器具本体11と光源ユニット12とが装着状態に保持される。 Therefore, as shown in FIG. 19, the wire spring 44 rotates in the folding rotation direction F2 due to the rotational urging force acting on the wire spring 44, and has already moved to the upper region of the receiving plate portion 72 of the spring receiver 41. The arm contact portion 50d of the pair of arm portions 50 abuts on the upper surface side of the receiving plate portion 72 of the spring receiver 41, and one side of the light source unit 12 uses the contact point between the arm contact portion 50d and the receiving plate portion 72 as a fulcrum. It is pulled upward toward the instrument body 11. As a result, one side of the light source unit 12 is attached to the instrument main body 11, and the instrument main body 11 and the light source unit 12 are held in the attached state.

なお、光源ユニット12の他側の押上げ操作時の動作についても、このような光源ユニット12の一側の押上げ操作時の動作と同様である。 The operation during the push-up operation on the other side of the light source unit 12 is the same as the operation during the push-up operation on one side of the light source unit 12.

また、光源ユニット12を器具本体11に装着する操作とは逆の操作を行うことによって、光源ユニット12を器具本体11から取り外すことができる。 Further, the light source unit 12 can be removed from the fixture main body 11 by performing the operation opposite to the operation of attaching the light source unit 12 to the fixture main body 11.

この取り外し時において、光源ユニット12を器具本体11から引き下げた状態で、光源ユニット12の一側の線ばね44および他側の線ばね44がそれぞればね受41に引っ掛かって止まる。このとき、光源ユニット12の一側の線ばね44および他側の線ばね44にはそれぞればね受41に引っ掛かる方向に回転力A2が生じているため、線ばね44を持って持ち上げながらフック部49をばね受41の引掛部75から外さない限り、線ばね44はばね受41から外れないため、光源ユニット12が不用意に脱落するのを防止できる。 At the time of this removal, the wire spring 44 on one side and the wire spring 44 on the other side of the light source unit 12 are each caught by the spring receiver 41 and stopped in a state where the light source unit 12 is pulled down from the instrument main body 11. At this time, since the rotational force A2 is generated in the wire spring 44 on one side and the wire spring 44 on the other side of the light source unit 12 in the direction of being hooked on the spring receiver 41, the hook portion 49 is lifted while holding the wire spring 44. The wire spring 44 does not come off from the spring receiver 41 unless is removed from the hook portion 75 of the spring receiver 41, so that the light source unit 12 can be prevented from accidentally falling off.

さらに、取り外し時において、例えば他側の線ばね44をばね受41から外し、図13のように一側の線ばね44で光源ユニット12が吊下げられた状態では、線ばね44が展開回転方向F1に回転力A1が生じて展開状態に保持されるため、例えば光源ユニット12を押し上げて線ばね44のフック部49をばね受41から外すことができ、作業性がよい。 Further, at the time of removal, for example, when the wire spring 44 on the other side is removed from the spring receiver 41 and the light source unit 12 is suspended by the wire spring 44 on one side as shown in FIG. 13, the wire spring 44 expands in the direction of unfolding rotation. Since the rotational force A1 is generated in F1 and is held in the deployed state, for example, the light source unit 12 can be pushed up and the hook portion 49 of the wire spring 44 can be removed from the spring receiver 41, which has good workability.

このように、本実施形態のばね装置40では、軸受部材46の一対の軸受部57の軸心aが、一対の軸受部57の相対する端部間を結ぶ仮想中心軸bに対して同一方向に対称的に傾いているため、仮想中心軸bの軸方向から見て一対の軸受部57の軸心aと線ばね44の一対のアーム部50とが重なる中立位置P3を境として、弾性変形の反発力により回転方向の一方と他方とのそれぞれに向けて回転力が生じさせることができ、簡単な構成で、使い勝手のよいばね装置40を提供できる。 As described above, in the spring device 40 of the present embodiment, the axial center a of the pair of bearing portions 57 of the bearing member 46 is in the same direction with respect to the virtual central axis b connecting the opposing ends of the pair of bearing portions 57. Because it is tilted symmetrically with respect to The repulsive force of the spring device 40 can generate a rotational force in each of one and the other in the rotational direction, and can provide an easy-to-use spring device 40 with a simple configuration.

すなわち、軸受部材45に軸受された線ばね44は、仮想中心軸bの軸方向から見て一対の軸受部57の軸心aと線ばね44の一対のアーム部50とが重なる中立位置P3において、一対のアーム部50の間隔が変化するように最も弾性変形した状態にある。さらに、一対の軸受部57によって線ばね44の一対の軸部51が仮想中心軸bに対して傾けられる角度は、一対のアーム部50が中立位置P3に位置するときが最も大きく、一対のアーム部50が中立位置P3よりも回転方向の一方または他方に向かって回転するのに従って小さくなっていく。これらにより、一対のアーム部50が中立位置P3よりも回転方向の一方または他方に少しでも回転操作すると、線ばね44の弾性変形に対して元に戻ろうとする反発力である弾性力により、回転方向の一方または他方に向けて回転力A1、A2を生じさせることができる。 That is, the wire spring 44 bearing on the bearing member 45 is at the neutral position P3 where the axial center a of the pair of bearing portions 57 and the pair of arm portions 50 of the wire spring 44 overlap when viewed from the axial direction of the virtual central axis b. , It is in the most elastically deformed state so that the distance between the pair of arm portions 50 changes. Further, the angle at which the pair of shaft portions 51 of the wire spring 44 are tilted by the pair of bearing portions 57 with respect to the virtual center axis b is the largest when the pair of arm portions 50 are located at the neutral position P3, and the pair of arms. The portion 50 becomes smaller as it rotates toward one or the other in the rotation direction from the neutral position P3. As a result, when the pair of arm portions 50 are rotated in one or the other direction in the rotation direction from the neutral position P3, the elastic force, which is a repulsive force that tries to return to the elastic deformation of the wire spring 44, causes the pair of arm portions to rotate. Rotational forces A1 and A2 can be generated in one or the other direction.

この線ばね44および軸受部材45を備えたばね装置40を器具本体11に光源ユニット12を装着する取付構造に用いることにより、作業性のよい照明装置10を提供できる。 By using the spring device 40 provided with the wire spring 44 and the bearing member 45 in a mounting structure in which the light source unit 12 is mounted on the fixture main body 11, it is possible to provide a lighting device 10 having good workability.

また、ばね装置40の押え部材46は、一方向に向けて回転する線ばね44の一対のアーム部50が接触し、線ばね44が所定の回転位置(押え方向切換位置P1)に回転するまでは一対のアーム部50の間隔が広がるように線ばね44を弾性変形させ、線ばね44が所定の回転位置(押え方向切換位置P1)を越えて一方向に回転した状態では一対のアーム部50の間隔が狭まる弾性力により線ばね44を一方向に向けて回転させるように押えることができ、簡単な構成で、使い勝手のよいばね装置40を提供できる。 Further, the presser member 46 of the spring device 40 is in contact with the pair of arm portions 50 of the wire spring 44 rotating in one direction until the wire spring 44 rotates to a predetermined rotation position (pressing direction switching position P1). Is to elastically deform the wire spring 44 so that the distance between the pair of arm portions 50 is widened, and when the wire spring 44 is rotated in one direction beyond a predetermined rotation position (pressing direction switching position P1), the pair of arm portions 50 The wire spring 44 can be pressed so as to rotate in one direction by the elastic force that narrows the interval between the springs, and a convenient spring device 40 can be provided with a simple configuration.

押え部材46は、板ばねで構成され、線ばね44の一対のアーム部50との接触時に一対の押え部61が弾性変形し、これら一対の押え部61の弾性力も加わって、線ばね44を一方向に向けて回転させるように押えることができる。 The presser member 46 is composed of a leaf spring, and when the wire spring 44 comes into contact with the pair of arm portions 50, the pair of presser portions 61 are elastically deformed, and the elastic force of the pair of presser portions 61 is also applied to form the wire spring 44. It can be pressed so that it rotates in one direction.

一対の押え部61は、一方向に回転する線ばね44の一対のアーム部50が所定の回転位置(押え方向切換位置P1)に回転するまでは一対のアーム部50の間隔が広がるようにガイドする拡開ガイド部64、および一方向に回転する線ばね44の一対のアーム部50が所定の回転位置(押え方向切換位置P1)を越えてからは一対のアーム部50の間隔が狭まるようにガイドする押えガイド部65を有するため、線ばね44を一方向に向けて回転させるように押えることができる。 The pair of presser portions 61 guide the pair of arm portions 50 so that the distance between the pair of arm portions 50 increases until the pair of arm portions 50 of the wire spring 44 rotating in one direction rotate to a predetermined rotation position (presser direction switching position P1). After the pair of arm portions 50 of the expansion guide portion 64 and the wire spring 44 rotating in one direction exceed a predetermined rotation position (pressing direction switching position P1), the distance between the pair of arm portions 50 is narrowed. Since the presser foot guide portion 65 for guiding is provided, the wire spring 44 can be pressed so as to rotate in one direction.

線ばね44を押える押え部材46が線ばね44を軸受する軸受部材45と同一部材に配置されるため、線ばね44と押え部材46との位置関係が一定となり、ばね装置40の安定した動作が可能となる。 Since the presser member 46 that presses the wire spring 44 is arranged in the same member as the bearing member 45 that bears the wire spring 44, the positional relationship between the wire spring 44 and the presser member 46 becomes constant, and the spring device 40 operates stably. It will be possible.

この押え部材46を備えたばね装置40を器具本体11に光源ユニット12を装着する取付構造に用いることにより、作業性のよい照明装置10を提供できる。 By using the spring device 40 provided with the pressing member 46 in a mounting structure in which the light source unit 12 is mounted on the fixture main body 11, it is possible to provide a lighting device 10 having good workability.

また、ばね受41の開口部74の幅方向の幅は、開口部74の引掛部75が設けられた縁部側である開口部74の下部側が線ばね44の一対のアーム部50間の幅よりも広く、引掛部75が設けられた開口部74の縁部側から反対側の縁部側である開口部74の上部側に向かうに従って狭くなるように形成されているため、線ばね44のフック部49を開口部74に挿通させて引掛部75に引っ掛ける操作を容易に行うことができ、かつ、第1の部材である器具本体11に第2の部材である光源ユニット12を組み合わせて装着する際に、線ばね44の一対のアーム部50が開口部74の上側に移動し、開口部74の両側縁で一対のアーム部50の幅方向の位置を位置決めすることにより、器具本体11に対して光源ユニット12を正しく組み合わせて装着できる。 Further, the width of the opening 74 of the spring receiver 41 in the width direction is the width between the pair of arm portions 50 of the wire spring 44 on the lower side of the opening 74 which is the edge side where the hook portion 75 of the opening 74 is provided. The wire spring 44 is wider than the wire spring 44 because it is formed to be wider and narrower from the edge side of the opening 74 provided with the hook 75 toward the upper side of the opening 74 which is the opposite edge side. The hook portion 49 can be easily inserted into the opening 74 and hooked on the hook portion 75, and the light source unit 12 which is the second member is mounted in combination with the instrument main body 11 which is the first member. At that time, the pair of arm portions 50 of the wire spring 44 moves to the upper side of the opening 74, and the position of the pair of arm portions 50 in the width direction is positioned at both side edges of the opening 74, thereby making the instrument body 11 On the other hand, the light source unit 12 can be installed in the correct combination.

ガイド板部71から折曲された受板部72に線ばね44のアーム当接部50dが当接することにより、器具本体11と光源ユニット12とを取付状態に保持することができる。 The arm contact portion 50d of the wire spring 44 comes into contact with the receiving plate portion 72 bent from the guide plate portion 71, so that the instrument main body 11 and the light source unit 12 can be held in the mounted state.

さらに、このばね受41と組み合わされるばね装置12が上述した押え部材46を備えることにより、器具本体11に光源ユニット12を装着する動作に対応して、線ばね44の一対のアーム部50が開口部74の上部側に移動し、開口部74の両側縁で一対のアーム部50の幅方向の位置を位置決めすることにより、器具本体11に対して光源ユニット12を正しく組み合わせて装着できることができるとともに、ガイド板部71から折曲された受板部72に線ばね44のアーム当接部50dが当接することにより、器具本体11と光源ユニット12とを取付状態に保持することができる。 Further, since the spring device 12 combined with the spring receiver 41 is provided with the presser member 46 described above, the pair of arm portions 50 of the wire spring 44 are opened in response to the operation of mounting the light source unit 12 on the instrument main body 11. By moving to the upper side of the portion 74 and positioning the position of the pair of arm portions 50 in the width direction on both side edges of the opening 74, the light source unit 12 can be correctly combined and mounted on the fixture body 11. The arm contact portion 50d of the wire spring 44 abuts on the receiving plate portion 72 bent from the guide plate portion 71, so that the instrument main body 11 and the light source unit 12 can be held in the mounted state.

また、照明装置10は、器具本体11の外形よりも光源ユニット12の外形が大きく、例えば天井への設置状態では、器具本体11が隠れ、光源ユニット12の光が出射する透光カバー27のみが見え、意匠性がよい。 Further, in the lighting device 10, the outer shape of the light source unit 12 is larger than the outer shape of the fixture main body 11. For example, in the state of being installed on the ceiling, the fixture main body 11 is hidden and only the translucent cover 27 from which the light of the light source unit 12 is emitted is emitted. It looks good and has a good design.

器具本体11および光源ユニット12の内側にばね装置40およびばね受41を配置し、器具本体11に光源ユニット12を装着した際に、ばね装置40の線ばね44が光源ユニット12の内側に折り畳まれることにより、このような照明装置10を実現できる。 When the spring device 40 and the spring receiver 41 are arranged inside the instrument body 11 and the light source unit 12, and the light source unit 12 is attached to the instrument body 11, the wire spring 44 of the spring device 40 is folded inside the light source unit 12. Thereby, such a lighting device 10 can be realized.

器具本体11には、取付孔18や配線孔19が設けられているとともに、2つの電源ユニット21および端子台22が取り付けられているが、線ばね44が折り畳まれる構造であるため、ばね装置40をコンパクトに構成でき、器具本体11の限られたスペース内にばね装置40およびばね受41を配置することができる。 The instrument body 11 is provided with a mounting hole 18 and a wiring hole 19, and two power supply units 21 and a terminal block 22 are mounted. However, since the wire spring 44 has a structure in which the wire spring 44 can be folded, the spring device 40 The spring device 40 and the spring receiver 41 can be arranged in the limited space of the instrument body 11.

なお、線ばね44の一対の軸部51は、一対のアーム部50の内側に向けて折曲されていてもよい。 The pair of shaft portions 51 of the wire spring 44 may be bent toward the inside of the pair of arm portions 50.

また、本実施形態では、軸受部材45の一対の軸受部57の軸心aは、線ばね44の中立位置P3において、線ばね44の一対の軸部51の先端側が一対のアーム部50に近付けさせる方向に傾いているが、逆に、線ばね44の一対の軸部51の先端側が一対のアーム部50に離れる方向に傾いていてもよい。この場合、線ばね44の中立位置P3において、一対のアーム部50の間隔を広がるように線ばね44の全体が弾性変形するため、上述した実施形態と同様の作用効果が得られる。 Further, in the present embodiment, the axial center a of the pair of bearing portions 57 of the bearing member 45 is such that the tip end side of the pair of shaft portions 51 of the wire spring 44 is close to the pair of arm portions 50 at the neutral position P3 of the wire spring 44. Although it is tilted in the direction of tilting, conversely, the tip end side of the pair of shaft portions 51 of the wire spring 44 may be tilted in the direction away from the pair of arm portions 50. In this case, at the neutral position P3 of the wire spring 44, the entire wire spring 44 is elastically deformed so as to widen the distance between the pair of arm portions 50, so that the same effect as that of the above-described embodiment can be obtained.

また、ばね装置40を器具本体11に取り付け、ばね受41を光源ユニット12に取り付けてもよい。 Further, the spring device 40 may be attached to the instrument main body 11 and the spring receiver 41 may be attached to the light source unit 12.

また、ばね装置40および取付装置13は、照明装置10以外にも、第1の部材と第2の部材とを互いに着脱可能に取り付ける取付構造などに適用することができる。 Further, the spring device 40 and the mounting device 13 can be applied to a mounting structure in which the first member and the second member are detachably attached to each other, in addition to the lighting device 10.
