Description

本発明の実施形態は、照明装置に関する。 Embodiments of the present invention relate to lighting devices.

従来、例えば、照明装置では、器具本体と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 is used to detachably attach a fixture body and a light source unit.

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。 A torsion spring is often used for such a spring device.

また照明装置では、器具本体または光源ユニット上に対向するように一対もしくは二対のばね装置を含む取付装置が配設されることが多いが、異なる機構の取付装置が一つの照明装置に配設されるものも存在する。その場合、取付装置毎に着脱作業が異なってくることから作業が煩雑になるという問題がある。 Also, in the lighting device, mounting devices including a pair or two pairs of spring devices are often arranged on the fixture body or the light source unit so as to face each other. There are also things that are done. In that case, there is a problem that the attachment/detachment work is different for each mounting device, and the work becomes complicated.

次に、図1および図3に示すように、取付装置13は、器具本体11の天面部15の一方の面上に取り付けられる第1の係合装置であるばね受41は引掛部75を備え、さらに光源ユニット12のベースプレート25の一方の面上に取り付けられる第2の係合装置であるばね装置40は係合部である中間にフック部49および軸部51を備えている。取付装置13は、1つのばね装置40と1つのばね受41とを1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 is a first engagement device mounted on one surface of the top surface portion 15 of the tool body 11. The spring receiver 41 has a hook portion 75. Furthermore, the spring device 40, which is the second engaging device mounted on one surface of the base plate 25 of the light source unit 12, has a hook portion 49 and a shaft portion 51 in the middle which is an engaging portion. Two mounting devices 13 are used, one spring device 40 and one spring bearing 41 being one set. The two sets of mounting devices 13 are arranged corresponding to the positions of the two opposite sides in different directions with respect to the positions of the two opposite sides of the fixture body 11 on which the two power supply units 21 are arranged.

そして、ばね装置40は、係合部材である線ばね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, which are engaging members.

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、係合部である中間のフック部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 made of, for example, a metal spring material. Stainless steel, for example, is used as the spring material. The wire spring 44 includes an intermediate hook portion 49 that is an engaging portion, a pair of arm portions 50 that are bent from both ends of the hook portion 49 so as to face each other substantially in parallel, and end portions of the arm portions 50. It has a pair of shaft portions 51 that are bent outward from each other.

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、ベースプレート25の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 distal side, an arm linear portion 50b provided on the proximal side, an arm connection portion 50c connecting the arm guide portion 50a and the arm linear portion 50b, and an arm An arm contact portion 50d is provided between the straight portion 50b and the arm connecting portion 50c and closer to the base end side than the arm guide portion 50a. The arm guide portion 50a is formed in a convex curved shape that protrudes upward from the base plate 25 when folded toward the inside of the light source unit 12, as shown in FIG. The arm contact portion 50d is formed by a bent portion between the arm linear portion 50b and the arm connection 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 outward from opposite ends of the pair of arm portions 50 . The pair of shaft portions 51 are bent substantially at right angles 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を回動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 a single metal plate. The bearing member 45 includes a mounting portion 54 attached to the base plate 25, a raised portion 55 raised from the mounting portion 54, and both lateral sides of the raised portion 55 bent so as to face the mounting portion 54. and a pair of bearing portions 57 provided at the ends of the pair of support portions 56 . The pair of bearing portions 57 are formed by bending the distal end portion of the support portion 56 into a tubular shape. A pair of shaft portions 51 of the wire spring 44 are inserted from the inner end sides of the pair of bearing portions 57 facing each other. A pair of shaft portions 51 of the wire spring 44 are rotatably supported by the pair of bearing portions 57 .

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が仮想中心線bに対して傾く角度αは、10°前後が好ましい。 The axis a of the pair of bearings 57 is symmetrically inclined in the same direction with respect to the virtual central axis b connecting the opposing ends of the pair of bearings 57 . The direction in which the axis a of the pair of bearings 57 is inclined is such that the angle β is 90° or more when the reference position P0 at which the pair of arms 50 of the wire spring 44 are parallel to the upper surface of the light source unit 12 is 0°. preferably in the range of 90-120°. In this embodiment, the direction in which the axis a of the pair of bearing portions 57 is inclined is, for example, the direction in which the angle β is 120°. Moreover, the angle α at which the axis a of the pair of bearings 57 is inclined with respect to the virtual center line b is preferably about 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を中心として回動可能とする。従って、仮想中心軸bは、線ばね44が回動する回動軸である。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。 4 and 5 (a front view of the wire spring 44 and the bearing member 45 at the neutral position P3 as viewed from arrow A in FIG. 4), the wire spring 44 supported by the bearing member 45 is positioned at the virtual center It is rotatable about the axis b. Therefore, the virtual central axis b is a rotation axis around which the wire spring 44 rotates. Further, the wire spring 44 supported by the bearing member 45 is at a neutral position P3 where the pair of arm portions 50 of the wire spring 44 and the axis a of the pair of bearing portions 57 overlap when viewed from the axial direction of the virtual central axis b. , 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, for example, a right angle or an obtuse angle with respect to the pair of arm portions 50, while the pair of bearing portions 57 of the bearing member 45 bend the pair of shaft portions. By symmetrically tilting the portions 51 in the same direction by the angle α, the entire wire spring 44 is in the most elastically deformed state so that the gap 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動方向の一方であって光源ユニット12の外側つまりばね装置40が取り付けられている板状の第2部材であるベースプレート25の中心とは離間する方向に開く展開回動方向F1と、回動方向の他方であって光源ユニット12の内側つまりばね装置40が取り付けられている板状の第2部材であるベースプレート25の中心に近づく方向に折り畳まれる折畳回動方向F2とのそれぞれに向けて回動力が生じる。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よりも展開回動方向F1または折畳回動方向F2に向かって回動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よりも展開回動方向F1または折畳回動方向F2に少しでも回動操作すると、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、展開回動方向F1または折畳回動方向F2に向けて回動力が生じる。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、より強い回動力が生じる。 Therefore, the wire spring 44 repels elastic deformation at a neutral position P3 where the axis a of the pair of bearings 57 and the pair of arms 50 of the wire spring 44 overlap when viewed from the axial direction of the virtual central axis b. a deployment rotation direction F1 in which force opens in one of the rotation directions and away from the center of the base plate 25, which is the plate-shaped second member to which the spring device 40 is attached, on the outside of the light source unit 12; In each of the folding rotation direction F2, which is the other of the rotation directions and is folded in the direction closer to the center of the base plate 25, which is the plate-shaped second member to which the spring device 40 is attached, which is the inside of the light source unit 12. A rotational force is generated toward the That is, the angle at which the pair of shaft portions 51 of the wire spring 44 is tilted with respect to the virtual central axis b by the pair of bearing portions 57 is the largest when the pair of arm portions 50 are positioned at the neutral position P3. It becomes smaller as the portion 50 rotates from the neutral position P3 in the unfolding rotation direction F1 or the folding rotation direction F2, and is the smallest at 90° to the neutral position P3. Therefore, if the pair of arm portions 50 are rotated from the neutral position P3 in the unfolding rotation direction F1 or the folding rotation direction F2 even by a small amount, the elastic deformation of the wire spring 44 is repelled to return to the original state. Due to a certain elastic force, a rotational force is generated in the unfolding rotational direction F1 or the folding rotational direction F2. Note that 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 is increased, resulting in a stronger turning force.

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動方向F2に向けて回動する線ばね44の一対のアーム部50が接触し、線ばね44が所定の回動位置(押え方向切換位置P1)に回動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が所定の回動位置(押え方向切換位置P1)を越えて一方向である折畳回動方向F2に回動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動方向F2に向けて回動させるように押えるものである。 As shown in FIGS. 3 and 7, the pressing member 46 is in contact with a pair of arm portions 50 of the wire spring 44 that rotates in one folding rotation direction F2, and the wire spring 44 The wire spring 44 is elastically deformed so that the gap between the pair of arms 50 widens until the wire spring 44 reaches the predetermined rotation position (holding direction switching position P1). When the position P1) is crossed and rotated in one folding rotation direction F2, the elastic force that narrows the gap between the pair of arm portions 50 directs the wire spring 44 in one folding rotation direction F2. It presses so that it rotates.

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 a leaf spring. A stainless plate, for example, is used as the leaf spring. The pressing member 46 has a mounting portion 60 and a pair of pressing portions 61 that are bent from both sides of the mounting portion 60 and with which the pair of arm portions 50 of the wire spring 44 come into contact.

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。 The mounting portion 60 has the mounting portion 54 of the bearing member 45 overlaid on the mounting portion 60 and is fixed to the base plate 25 integrally with the mounting portion 54 by screwing. 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。 A pair of pressing portions 61 are formed from raised portions 62 bent inward from both sides of the mounting portion 60 so as to narrow the distance from each other, and from the upper portion of the raised portions 62 to the outside so as to widen the distance from each other. It has a guide portion 63 that is bent toward.

一対の押え部61(ガイド部63)は、一方向である折畳回動方向F2に回動する線ばね44の一対のアーム部50が所定の回動位置(押え方向切換位置P1)に回動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動方向F2に回動する線ばね44の一対のアーム部50が所定の回動位置(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動方向F2に回動する線ばね44の一対のアーム部50の所定の回動位置(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 parts 61 (guide parts 63) rotate in one direction, that is, the folding rotation direction F2. A widening guide portion 64 that guides the pair of arm portions 50 so that the distance between the pair of arm portions 50 widens until it moves, and a pair of arm portions 50 of a wire spring 44 that rotates in one direction, the folding rotation direction F2, in a predetermined direction. A presser guide portion 65 is provided to guide the pair of arm portions 50 so that the distance between the pair of arm portions 50 narrows after passing the rotation position (presser direction switching position P1). Between the expanding guide portion 64 and the pressing guide portion 65, there is a switch for switching between guiding so as to widen the gap between the pair of arm portions 50 and guiding so as to narrow the interval between the pair of arm portions 50. A rib 66 is provided. The position of the switching portion 66 corresponds to a predetermined rotational position (pressing direction switching position P1) of the pair of arm portions 50 of the wire spring 44 that rotates in one folding rotational direction F2. . The width between the expanding guide portions 64 of the pair of pressing portions 61 and the width between the pressing guide portions 65 are set 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を折畳回動方向F2に回動させていくと、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、折畳回動方向F2に回動させていく線ばね44の一対のアーム部50が所定の回動位置(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に沿って折畳回動方向F2に移動し、線ばね44が折畳回動方向F2に回動する回動付勢力が生じる。 Then, while the pair of arm portions 50 of the wire spring 44 are in contact with the expanding guide portions 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. , the wire spring 44 is elastically deformed so that the interval between the pair of arm portions 50 widens, and the holding member 46 is elastically deformed so that the interval between the pair of holding portions 61 is narrowed. Further, the pair of arm portions 50 of the wire spring 44, which is rotated in the folding rotation direction F2, crosses the predetermined rotation position (holding direction switching position P1), that is, the switching portion 66, and the pair of holding members 46 When the presser guide portion 65 of the presser portion 61 comes into contact with the presser guide portion 65 of the presser member 46, the pair of arm portions 50 of the wire spring 44 move against the pair of presser member 46 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 wire spring 44 moves in the folding rotation direction F2 along the pressing guide portion 65 of the pressing portion 61, and a rotation biasing force is generated to rotate the wire spring 44 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動方向F1に向けた回動力A1と、光源ユニット12の内側に折り畳まれる折畳回動方向F2に向けた回動力A2とが生じる。線ばね44は、展開回動方向F1に生じる回動力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に回動して保持される。線ばね44は、折畳回動方向F2に生じる回動力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に回動して保持される。この線ばね44に生じる展開回動方向F1および折畳回動方向F2の回動力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, referring to FIG. 4, the movement of the wire spring 44 is summarized. With the neutral position P3 as a boundary, the wire spring 44 is folded inside the light source unit 12 by the repulsive force of the elastic deformation of the wire spring 44. A turning force A2 is generated in the folding turning direction F2. The wire spring 44 is rotated from the neutral position P3 to the deployed self-supporting position P4 abutting on the periphery of the base plate 25 by a rotating force A1 generated in the deployed rotation direction F1, and is held. The wire spring 44 is rotated from the neutral position P3 to the folding self-supporting position P2 where it abuts on the expansion guide 64 of the pressing member 46 by the rotation 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 are such that the wire spring 44 can maintain its self-sustaining state. Independent state is canceled.

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動方向F1に向けて回動力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動方向F2に向けて回動力B2が生じる。この線ばね44に生じる折畳回動方向F2の回動力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、回動力A1、A2と回動力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 expanding guide portion 64 and the pressing guide portion 65, with the pressing direction switching position P1 as a boundary. As a result, a turning force B1 is generated in the unfolding rotation direction F1 between the presser direction switching position P1 and the folding independent position P2, and folding rotation is performed between the presser direction switching position P1 and the maximum presser position P5. A turning force B2 is generated in the moving direction F2. The rotational force B2 in the folding rotational 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 itself. Note that the strengths of the turning forces A1, A2 and the turning forces B1, B2 have a relationship of A1, A2<B1, 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 bearing 41 of the mounting device 13 is integrally formed by bending a single metal plate. The spring bearing 41 includes a mounting plate portion 70, a guide plate portion 71 bent from one side of the mounting plate portion 70, a receiving plate portion 72 bent from the guide plate portion 71, and the other side of the mounting plate portion 70. It has a cover portion 73 that is bent from the bottom. Further, the spring bearing 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 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 obliquely protrudes 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に光源ユニット12を装着し固定する際に器具本体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すると同時に、仮にケーブルを線ばね近傍に巻き込む形で光源ユニット12を装着してしまい、線ばね44の閉じが不十分となり十分な固定ができなかった場合、必ずカバー部73のいずれかの面(後面カバー部76、側面カバー部77)がケーブルを挟み込む状態となり、装着時に不自然な厚みが生じることで異常が検知できるという効果も有している。カバー部73が存在しない場合は、線ばね44にケーブルが干渉して線ばね44の閉じが不十分の場合でも、外観上何も変化がなく検知できない可能性が存在する。 The cover portion 73 includes a rear cover portion 76 that is bent downward from the mounting plate portion 70, and side surfaces that are bent from both sides of the rear cover portion 76 so as to be arranged below both sides of the mounting plate portion 70. It has a cover portion 77 . The lower area of the mounting plate portion 70 is surrounded by the cover portion 73 together with the guide plate portion 71, and for example, when the light source unit 12 is attached and fixed to the device main body 11, there is a gap between the device main body 11 and the light source unit 12. The light source unit 12 is mounted in such a manner that the cable with a connector is prevented from entering, and at the same time, the cable is temporarily wound in the vicinity of the wire spring 44. As a result, the wire spring 44 is not sufficiently closed and cannot be sufficiently fixed. In this case, one of the surfaces of the cover portion 73 (rear cover portion 76, side cover portion 77) is always in a state of sandwiching the cable. . If the cover part 73 does not exist, even if the cable interferes with the wire spring 44 and the wire spring 44 is not sufficiently closed, there is a possibility that there is no change in appearance and detection cannot be performed.

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 formed continuously from the guide plate portion 71 to part of the mounting plate portion 70 . The width in the width direction of the opening 74 formed in the guide plate portion 71 is such that the lower side of the opening 74, which is the edge side of the opening 74 where the hook portion 75 is provided, is between the pair of arm portions 50 of the wire spring 44. , and is formed in a substantially trapezoidal shape so that it becomes narrower from the edge side of the opening 74 where the hook 75 is provided toward the upper side of the opening 74, which is the opposite edge side. . The width of the upper portion of the opening 74 enables the width between the pair of arm portions 50 of the wire spring 44 to be restricted in the width direction, and is formed to be approximately 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 hooking portion 75 projects from the guide plate portion 71 into the opening portion 74 so that the hook portion 49 of the wire spring 44 can be hooked thereon. The hook portion 75 is provided at the center of the width direction of the opening portion 74 at the lower edge portion of the opening portion 74 , which is the edge portion of the opening portion 74 away from the mounting plate portion 70 . The hooking portion 75 is formed to have a substantially L-shaped cross section so that the tip end thereof protrudes toward the inner surface 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 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 at 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から展開回動方向F1に少し回動操作すると、上述したように、線ばね44の弾性力により、展開回動方向F1に向けて回動力A1が生じる。そのため、図10に示すように、線ばね44が展開回動方向F1に回動し、係合部であるフック部49および一対のアーム部50の先端側が光源ユニット12を構成する板状の第2部材であるベースプレート25の外縁部から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。 When the pair of arm portions 50 of the wire spring 44 are slightly rotated from the neutral position P3 in the deployment rotation direction F1, the elastic force of the wire spring 44 rotates the wire spring 44 in the deployment rotation direction F1 as described above. Power A1 is generated. Therefore, as shown in FIG. 10, the wire spring 44 rotates in the deployment rotation direction F1, and the tip side of the hook portion 49 and the pair of arm portions 50, which are the engaging portions, form the plate-shaped first portion of the light source unit 12. Therefore, as shown in FIG. It is held at a developed self-supporting position P4 developed so as to protrude outward from the outer edge of the base plate 25, which is two members.

一方、線ばね44の一対のアーム部50を中立位置P3から折畳回動方向F2に少し回動操作すると、上述したように、線ばね44の弾性力により、折畳回動方向F2に向けて回動力A2が生じる。そのため、図11に示すように、線ばね44が折畳回動方向F2に回動し、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 are slightly rotated from the neutral position P3 in the folding rotation direction F2, the elastic force of the wire spring 44 causes the arm portion 50 to rotate in the folding rotation direction F2 as described above. rotation force A2 is generated. 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 incline toward the inside of the light source unit 12, and the pair of arm portions 50 It is held at the folding self-supporting position P2 in contact with the pair of pressing portions 61 (expanding guide portions 64) of the pressing member .

また、図12には、光源ユニット12の線ばね44が装着固定位置(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には折畳回動方向F2に向けて回動力B2が生じる。 12 shows a state in which the wire spring 44 of the light source unit 12 is in the mounting and fixing position (between the pressing direction switching position P1 and the maximum pressing position P5). The wire spring 44 is folded over the light source unit 12, and the pair of arm portions 50 come into contact with the pair of pressing portions 61 (pressing guide portions 65) of the pressing member 46. As shown in FIG. In this state, as described above, due to the elastic force of the wire spring 44 and the pressing member 46, the wire spring 44 generates a turning force B2 in the folding turning 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の装着固定手順を説明する。 Next, a procedure for attaching and fixing the light source unit 12 to 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に回動した状態とする。展開自立位置P4の線ばね44は、回動操作しない限り、光源ユニット12を傾けたり回動させたりなどしても、展開自立位置P4に容易に保持されている。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に回動した状態、折畳自立位置P2に回動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 deployment independent position P4 where the light source unit 12 protrudes outward. The wire spring 44 at the developed independent position P4 is easily held at the developed independent 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 the state of being rotated to the unfolded self-supporting position P4 or the state of being rotated to the folding self-supporting 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は必要ない。また、線ばね44のフック部49は光源ユニット12を構成する板状の第2部材であるベースプレート25の外縁部から外側方に突出するように展開しているため、光源ユニット12を線ばね44が上方に位置するよう垂直方向に保持するだけで引掛部75に引っ掛けることが可能となり作業性を向上できる。フック部49がベースプレート25の外縁部から外側方に突出していない場合は、光源ユニット12の上方に位置するフック部49を光源ユニット12水平方向に保持しながら引掛部75に引っ掛ける必要があり作業性が悪い。 One side of the light source unit 12 is directed upward, and the hook portion 49 of the wire spring 44 and the tip side of the pair of arm portions 50 arranged on one side of the light source unit 12 are connected to the opening 74 of the spring receiver 41 of the instrument main body 11. , and the hook portion 49 is hooked on the hook portion 75 . At this time, since the wire spring 44 is held at the deployed self-supporting position P4, there is no need to manually hold the wire spring 44 in the deployed state. Further, since the hook portion 49 of the wire spring 44 is developed so as to protrude outward from the outer edge portion of the base plate 25, which is the plate-shaped second member that constitutes the light source unit 12, the light source unit 12 is attached to the wire spring 44. It can be hooked to the hooking portion 75 only by holding it in the vertical direction so that it is positioned upward, and workability can be improved. If the hook portion 49 does not protrude outward from the outer edge of the base plate 25, the hook portion 49 located above the light source unit 12 needs to be hooked on the hook portion 75 while holding the light source unit 12 horizontally. is bad.

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, the opening 74 of the spring support 41 has a lower width wider than the width between the pair of arm portions 50, so that the hook portion 49 and the tip side of the pair of arm portions 50 are attached to the instrument. It can be easily inserted into the opening 74 of the spring bearing 41 of the main body 11, and the hook portion 49 can be easily hooked on the hook portion 75, resulting in good operability.

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 from one side of the fixture body 11. As shown in FIG. In this one-sided suspended state, the connector-equipped cable from the power supply unit 21 and the connector-equipped cable from the light source unit are connector-connected.

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に回動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 moved to the spring support 41. As shown in FIG. , and the hook portion 49 is hooked on the hook portion 75 . At this time as well, due to the shape of the opening 74 of the spring receiver 41, it is easy to insert the hook portion 49 and the distal ends of the pair of arm portions 50 into the opening 74 of the spring receiver 41 of the instrument 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 portion 74 of the spring receiver 41, the wire spring 44 is pivoted to the folding self-sustaining position P2 so that the hook portion 49 is guided to the opening portion 74 of the spring receiver 41. Easy to enter and good workability.

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、折畳回動方向F2に向けて回動力A2が生じる。そのため、この線ばね44の回動力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 turning force A2 is generated in the folding turning direction F2. Therefore, the turning force A2 of the wire spring 44 acts to shift one side of the light source unit 12 to the proper position with respect to the fixture body 11, and the wire spring 44 on the other side of the light source unit 12 is attached to the spring support 41. Easy to put on.

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動力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 from both sides of the apparatus main body 11. As shown in FIG. 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 in the center parallel to the fixture body 11 . At this time, since the wire spring 44 on one side of the light source unit 12 and the wire spring 44 on the other side of the light source unit 12 generate a turning force A2 in the direction in which they are caught by the spring receiver 41, the hook portion 49 is moved while holding the wire spring 44 and lifting it. Since the wire spring 44 does not come off the spring receiver 41 unless the wire spring 44 is removed from the hooking portion 75 of the spring receiver 41, the light source unit 12 does not fall off accidentally.

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。 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。 After that, the light source unit 12 is pushed up and attached to the fixture main body 11 . At this time, one side and the other side of the light source unit 12 may be pushed up in parallel to attach the light source unit 11 to the fixture body 11, or one side or the other side of the light source unit 12 may be pushed up one by one to attach the fixture. It may be attached to the main body 11 . FIG. 16 shows a state in which one side of the light source unit 12 is pushed up by pushing up the other side of the light source unit 12 . 16 to 19, the operation when one side of the light source unit 12 is pushed up will be described.

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 the wire spring 44 connects the one side of the light source unit 12 to the fixture main body. It is in a state of being 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 (expanding guide portions 64) of the pressing member 46. As shown in FIG.

光源ユニット12の一側を押し上げていくと、線ばね44の回動力A2によって線ばね44が折畳回動方向F2に回動していく。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の折畳回動方向F2への回動が折畳自立位置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。 As 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 rotation 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 (expanding guide portions 64) of the pressing member 46, and the wire spring 44 is folded. The rotation in the moving direction F2 is once stopped at the self-standing folding position P2, and thereafter the wire spring 44 is pushed up together with one side of the light source unit 12. As shown in FIG.

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を折畳回動方向F2に強制的に回動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が折畳回動方向F2に回動しながらばね受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 portions 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 come into contact with the lower surface of the mounting plate portion 70 of the spring support 41, and the arm guide portions 50a rise is regulated. Therefore, when one side of the light source unit 12 is further pushed up, 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 . As described above, the wire spring 44 moves toward the spring support 41 while rotating in the folding rotation direction F2, so that the arm abutment portions 50d of the pair of arm portions 50 move toward the receiving plate portions 72 of the spring support 41. moves to the upper region of

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 arms 50 move to the narrow region on the upper side of the opening 74, and the widthwise position of the pair of arms 50 is restricted by both side edges of the opening 74. . As a result, the position of the light source unit 12 to be pushed 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 with the fixture main body 11 and attached.

この一連の動作を行うとき、アームガイド部50aの凸湾曲部分が線ばね44を折畳回動方向F2に誘い込むガイドの役割を担っているが、図15に示すように光源ユニット12が器具本体11に対して両側吊下げ状態となった際に、アーム部50と光源ユニット12のベースプレート25とのなす角が鋭角となるようにばね受41とばね装置40を配設することにより、アームガイド部50aの凸湾曲部の突出が小さくても十分な誘い込み効果を得ることができ、照明器具全体の厚みを小さくすることができる。 When performing this series of operations, the convex curved portion of the arm guide portion 50a serves as a guide for guiding the wire spring 44 in the folding and rotating direction F2. By arranging the spring receiver 41 and the spring device 40 so that the angle formed by the arm part 50 and the base plate 25 of the light source unit 12 becomes an acute angle when both sides are suspended from the light source unit 11, the arm guide Even if the protrusion of the convex curved portion of the portion 50a is small, a sufficient luring effect can be obtained, and the thickness of the lighting fixture as a whole can be reduced.

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を折畳回動方向F2に回動させていくと、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, while the pair of arm portions 50 of the wire spring 44 are in contact with the expanding guide portions 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 to fold the wire spring 44. As it rotates in the moving direction F2, the wire spring 44 is elastically deformed so that the gap between the pair of arm portions 50 widens, and the holding member 46 is elastically deformed so that the gap 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、折畳回動方向F2に回動させていく線ばね44の一対のアーム部50が所定の回動位置(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に沿って折畳回動方向F2に回動するように、線ばね44に折畳回動方向F2に回動する回動力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 spring 44, which is rotated in the folding rotation direction F2, reaches a predetermined rotation position (pressing direction switching position P1). It crosses the switching portion 66 and contacts the pressing guide portions 65 of the pair of pressing portions 61 of the pressing member 46 . As a result, the pair of arm portions 50 of the wire spring 44 move along the pressing guide portions 65 of the pair of pressing portions 61 of the pressing member 46 due to the elastic force that is the repulsive force against the elastic deformation of the wire spring 44 and the pressing member 46. A turning force B2 is generated to rotate the wire spring 44 in the folding turning direction F2 so that the wire spring 44 turns in the folding turning direction F2.

そのため、図19に示すように、線ばね44に作用する回動付勢力により、線ばね44が折畳回動方向F2に回動し、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、ばね受け41とばね装置40が弾性係合することで器具本体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とが装着状態に固定される。なおこの状態において器具本体11と光源ユニット12を固定している固定力は、器具本体11から光源ユニット12を取り外すことが可能でかつ光源ユニットの自重で取り外れないような固定力であれば良い。 Therefore, as shown in FIG. 19, the wire spring 44 is rotated in the folding rotation direction F2 by the rotation biasing force acting on the wire spring 44, and has already moved to the area above the receiving plate portion 72 of the spring support 41. The arm abutment portions 50d of the pair of arm portions 50 that were engaged with each other abut against the upper surface side of the receiving plate portion 72 of the spring support 41, and the light source unit 12 is moved around the contact point between the arm abutting portions 50d and the receiving plate portion 72 as a fulcrum. One side of the is pulled upward toward the instrument body 11 . As a result, one side of the light source unit 12 is attached to the fixture main body 11 by elastic engagement between the spring receiver 41 and the spring device 40, and the fixture main body 11 and the light source unit 12 are fixed in the mounted state. It should be noted that the fixing force for fixing the fixture main body 11 and the light source unit 12 in this state may be any fixing force that allows the light source unit 12 to be removed from the fixture main body 11 and that the light source unit does not come off due to its own weight. .

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。 It should be noted that the operation when the other side of the light source unit 12 is pushed up is the same as the operation when the one side of the light source unit 12 is pushed up.

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 an operation opposite to the operation of attaching the light source unit 12 to the fixture main body 11 .

この取外し時において、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動力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, with the light source unit 12 pulled down from the fixture body 11, the wire spring 44 on one side and the wire spring 44 on the other side of the light source unit 12 are caught by the spring bearings 41 and stopped. At this time, since the wire spring 44 on one side of the light source unit 12 and the wire spring 44 on the other side of the light source unit 12 generate a turning force A2 in the direction in which they are caught by the spring receiver 41, the hook portion 49 is moved while holding the wire spring 44 and lifting it. Since the wire spring 44 does not come off from the spring receiver 41 unless the wire spring 44 is removed from the hook portion 75 of the spring receiver 41, it is possible to prevent the light source unit 12 from accidentally falling off.

さらに、取外し時において、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が展開回動方向F1に回動力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 detachment, for example, the wire spring 44 on the other side is removed from the spring holder 41, and when the light source unit 12 is suspended by the wire spring 44 on one side as shown in FIG. Since the turning force A1 is generated in the direction F1 and the unfolded state is maintained, for example, the hook portion 49 of the wire spring 44 can be removed from the spring receiver 41 by pushing up the light source unit 12, resulting in 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線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動方向の一方と他方とのそれぞれに向けて回動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。 Thus, in the spring device 40 of the present embodiment, the axial centers a of the pair of bearing portions 57 of the bearing member 46 are aligned in the same direction with respect to the imaginary center line b connecting the opposing ends of the pair of bearing portions 57. symmetrically, elastic deformation occurs at a neutral position P3 where the axis a of the pair of bearings 57 and the pair of arms 50 of the wire spring 44 overlap when viewed from the axial direction of the virtual central axis b. can generate a turning force in one and the other of the turning directions by the repulsive force of the spring device 40, which has a simple structure and is easy to use.

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よりも回動方向の一方または他方に向かって回動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よりも回動方向の一方または他方に少しでも回動操作すると、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、回動方向の一方または他方に向けて回動力A1、A2を生じさせることができる。 That is, the wire spring 44 supported by the bearing member 45 is at a neutral position P3 where the pair of arm portions 50 of the wire spring 44 and the axis a of the pair of bearing portions 57 overlap when viewed from the axial direction of the virtual center axis b. , is in the most elastically deformed state so that the distance between the pair of arm portions 50 changes. Furthermore, the angle at which the pair of shaft portions 51 of the wire spring 44 is tilted with respect to the virtual central axis b by the pair of bearing portions 57 is the largest when the pair of arm portions 50 are positioned at the neutral position P3. It becomes smaller as the portion 50 rotates from the neutral position P3 toward one or the other of the rotation directions. As a result, when the pair of arm portions 50 are rotated from the neutral position P3 in one or the other direction, an elastic force, which is a repulsive force that tends to return to the elastic deformation of the wire spring 44, is generated. , and the rotational forces A1 and A2 in one or the other of the rotational directions.

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 including the wire spring 44 and the bearing member 45 in the mounting structure for mounting the light source unit 12 on the fixture body 11, the lighting device 10 with good workability can be provided.

また、ばね装置40の押え部材46は、一方向に向けて回動する線ばね44の一対のアーム部50が接触し、線ばね44が所定の回動位置(押え方向切換位置P1)に回動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が所定の回動位置(押え方向切換位置P1)を越えて一方向に回動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動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。 The holding 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, and the wire spring 44 is rotated to a predetermined rotation position (pressing direction switching position P1). The wire spring 44 is elastically deformed so that the gap between the pair of arm portions 50 widens until it moves. The wire spring 44 can be held so as to be rotated in one direction by the elastic force that narrows the distance between the pair of arm portions 50, and the spring device 40 can be provided with a simple configuration and good usability.

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動させるように押えることができる。 The pressing member 46 is composed of leaf springs, and when the wire spring 44 contacts the pair of arm portions 50, the pair of pressing portions 61 is elastically deformed. It can be pressed so as to rotate in one direction.

一対の押え部61は、一方向に回動する線ばね44の一対のアーム部50が所定の回動位置(押え方向切換位置P1)に回動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、および一方向に回動する線ばね44の一対のアーム部50が所定の回動位置(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動させるように押えることができる。 In the pair of pressing portions 61, the gap between the pair of arm portions 50 widens until the pair of arm portions 50 of the wire spring 44 that rotates in one direction rotates to a predetermined rotating position (pressing direction switching position P1). After the pair of arm portions 50 of the expanding guide portion 64 and the wire spring 44 rotating in one direction passes a predetermined rotating position (pressing direction switching position P1), the pair of arm portions 50 Since it has the pressing guide portion 65 that guides so that the gap is narrowed, 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 pressing member 46 that presses the wire spring 44 is arranged on the same member as the bearing member 45 that bears the wire spring 44, the positional relationship between the wire spring 44 and the pressing member 46 is constant, and the spring device 40 can operate stably. It becomes possible.

また、取り外しの際は、光源ユニット12の4辺のいずれかのうちどこの辺をつかみ下方へ引き下ろしても係合部材が安定して回動されるので、方向性を気にせず取り外し作業が容易となる。 In addition, when removing the light source unit 12, the engaging member can be stably rotated even if any one of the four sides of the light source unit 12 is grasped and pulled downward, so the removal work is easy without worrying about the directionality. becomes.

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 having the pressing member 46 in the mounting structure for mounting the light source unit 12 on the fixture body 11, the lighting device 10 with good workability can be provided.

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、器具本体11に光源ユニット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。 In addition, the width of the opening 74 of the spring bearing 41 in the width direction is such that the lower side of the opening 74, which is the edge side of the opening 74 where the hook 75 is provided, is the width between the pair of arm portions 50 of the wire spring 44. , and narrows from the edge side of the opening 74 where the hook 75 is provided toward the upper side of the opening 74, which is the opposite edge side, so that the wire spring 44 The operation of inserting the hook portion 49 into the opening portion 74 and hooking it on the hook portion 75 can be easily performed, and when the light source unit 12 is combined and attached to the device main body 11, the pair of arm portions of the wire spring 44 50 moves to the upper side of the opening 74, and by positioning the widthwise positions of the pair of arm portions 50 at both side edges of the opening 74, the light source unit 12 can be correctly combined with the fixture body 11 and attached.

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。 By abutting the arm abutting portion 50d of the wire spring 44 against the receiving plate portion 72 bent from the guide plate portion 71, the instrument main body 11 and the light source unit 12 can be held in the attached 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, the spring device 12 combined with the spring receiver 41 is provided with the pressing member 46 described above, so that the pair of arm portions 50 of the wire spring 44 are opened corresponding to the operation of attaching the light source unit 12 to the fixture body 11. By moving to the upper side of the portion 74 and positioning the positions of the pair of arm portions 50 in the width direction at both side edges of the opening portion 74, the light source unit 12 can be correctly assembled and attached to the fixture body 11. By bringing the arm contact portion 50d of the wire spring 44 into contact with the receiving plate portion 72 bent from the guide plate portion 71, the fixture main body 11 and the light source unit 12 can be held in the attached 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 body 11. For example, when installed on the ceiling, the fixture body 11 is hidden, and only the translucent cover 27 through which the light from the light source unit 12 is emitted is provided. It looks good and has 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。 The spring device 40 and the spring receiver 41 are arranged inside the fixture body 11 and the light source unit 12, and when the light source unit 12 is attached to the fixture body 11, the wire spring 44 of the spring device 40 is folded inside the light source unit 12. Thus, 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 device main 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. can be configured compactly, and 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. As shown in FIG.

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 sides of the pair of shaft portions 51 of the wire spring 44 approach the pair of arm portions 50 at the neutral position P3 of the wire spring 44. However, conversely, the tip sides of the pair of shaft portions 51 of the wire spring 44 may be inclined 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 effects as those of the above-described embodiment can be obtained.

また、本実施例では、取付装置13として、1つのばね装置40と1つのばね受41とを1組として2組用いた例を示したが、3組以上の取り付け装置13を用いた取付機構を構成しても良い。例えば、3組の取り付け装置13を三角形(正三角形、二等辺三角形など)の位置関係で配設したり、4組の取り付け装置13を四角形(正方形、長方形、ひし形、平行四辺形など)の位置関係で配設したりしても良い。 Further, in the present embodiment, an example of using two sets of one spring device 40 and one spring bearing 41 as one set of the mounting device 13 is shown. may be configured. For example, three sets of mounting devices 13 are arranged in the positional relationship of a triangle (equilateral triangle, isosceles triangle, etc.), or four sets of mounting devices 13 are arranged in the positional relationship of a quadrangle (square, rectangle, rhombus, parallelogram, etc.). They may be arranged in relation to each other.

また、取付装置13のうちのばね受け41と電源ユニット21との位置関係についても実施例に示した位置に限定されるものではない。本実施例の電源ユニット21は天面部15の一方の面で器具本体11の対向する2辺に沿って配設され、ばね受け41は2つの電源ユニット21が配置される位置に対して異なる方向の対向する2辺の位置に配設されている。器具本体11と光源ユニット12とを着脱する際にはばね受け41を中心に上下方向に外力がかり、天面部15がゆがむ可能性があるが、このばね受け41と電源ユニット21の位置関係であれば、補強財のように電源ユニット21が配置されているため、着脱時に天面部15がゆがむことを抑制する効果を有している。このばね受け41と電源ユニット21の位置関係を、例えば、ばね受け41の位置はそのままで、2つの電源ユニット21は1対のばね受け41を結ぶ仮想線と直交する方向に長手方向が位置するように一対のばね装置間の領域に配設してもよい。このばね受け41と電源ユニット21の位置関係であれば、ゆがみ抑制効果を得つつ、一般的に配線が引き出される電源ユニット21の端部とばね装置41を含む取付装置13の距離を離すことができるため、配線の挟み込み抑制の効果も得ることができる。 Further, the positional relationship between the spring bearing 41 of the mounting device 13 and the power supply unit 21 is not limited to the positions shown in the embodiments. The power supply unit 21 of this embodiment is arranged along two opposite sides of the instrument body 11 on one surface of the top surface 15, and the spring receivers 41 are arranged in different directions with respect to the positions where the two power supply units 21 are arranged. are disposed at two opposite sides of the . When attaching and detaching the fixture main body 11 and the light source unit 12, an external force is applied in the vertical direction around the spring retainer 41, and the top surface 15 may be distorted. For example, since the power supply unit 21 is arranged like a reinforcement, it has the effect of suppressing the distortion of the top surface portion 15 when attaching and detaching. The positional relationship between the spring bearings 41 and the power supply unit 21 is such that, for example, the position of the spring bearings 41 remains the same, and the longitudinal direction of the two power supply units 21 is positioned in a direction orthogonal to the virtual line connecting the pair of spring bearings 41. may be arranged in the region between the pair of spring devices. With this positional relationship between the spring support 41 and the power supply unit 21, it is possible to keep the distance between the end of the power supply unit 21 from which wires are generally drawn out and the mounting device 13 including the spring device 41 while obtaining the effect of suppressing distortion. Therefore, it is possible to obtain the effect of suppressing the pinching of the wiring.

また、実施例や上記の他の事例では電源の数量が2つの例を示しているが、1つもしくは3つ以上の電源を有していても良いし、電源ユニット21、端子台22を配設するのは器具本体11の天面部15側ではなく、光源ユニット12のベースプレート25側に同様に配設しても良い。 In addition, although the embodiment and other examples above show an example in which there are two power supplies, one or more than three power supplies may be provided, and the power supply unit 21 and the terminal block 22 may be arranged. It may be provided on the base plate 25 side of the light source unit 12 instead of on the top surface portion 15 side of the fixture body 11 in the same manner.

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。 In addition to the lighting device 10, the spring device 40 and the mounting device 13 can also be applied to a mounting structure for detachably mounting the first member and the second member to each other.
