Description
本発明は、設置部に取り付けられる枠体および前記枠体に支持される灯体を備える照明器具に関するものである。 The present invention relates to a luminaire including a frame attached to an installation portion and a lamp supported by the frame.
従来、天井等に設けられた埋設孔に埋め込まれてダウンライト等に適用される照明器具が使用されている。例えば、特許文献１には、図７に示すように、枠体１０１と、枠体１０１とは別構成で光源としてＬＥＤを有する灯体１０２とを備える照明器具１００が開示されている。 2. Description of the Related Art Conventionally, a lighting fixture that is embedded in a buried hole provided in a ceiling or the like and applied to a downlight or the like has been used. For example, as shown in FIG. 7, Patent Literature 1 discloses a lighting fixture 100 including a frame body 101 and a lamp body 102 having a configuration different from that of the frame body 101 and having an LED as a light source.
特許文献１に記載の照明器具は、枠体１０１の下方から灯体１０２を挿入して灯体１０２を枠体１０１に取り付ける。より具体的には、枠体１０１が第１枠部１０３と第２枠部１０４を有し、枠体１０１に挿入された灯体１０２の段部１０５が第１枠部１０３の段部当接部１０６に当接し、灯体１０２に対して枠体１０１を回動させることにより、灯体１０２の受部１０７が第１枠部１０３の掛止部１０８に当接することで灯体１０２が枠体１０１に取り付けられる。つまり灯体１０２の枠体１０１への挿入方向の位置決めは、段部１０５および段部当接部１０６の当接によりなされている。 In the luminaire described in Patent Document 1, the lamp body 102 is inserted from below the frame body 101 to attach the lamp body 102 to the frame body 101. More specifically, the frame body 101 has a first frame portion 103 and a second frame portion 104, and the step portion 105 of the lamp body 102 inserted into the frame body 101 is in contact with the step portion of the first frame portion 103. When the frame body 101 is rotated with respect to the lamp body 102 by abutting against the portion 106, the receiving section 107 of the lamp body 102 abuts against the latching section 108 of the first frame section 103, so that the lamp body 102 is framed. It is attached to the body 101. That is, the lamp body 102 is positioned in the insertion direction of the lamp body 102 in the frame 101 by the contact between the step portion 105 and the step portion contact portion 106.
しかしながら、特許文献１に記載の照明器具１００にあっては、挿入方向における枠体１０１に対する灯体１０２の位置決め、つまり第１枠部１０３への放熱フィン１０９の挿入方向の位置決めは考慮されているものの、挿入方向に対する灯体１０２の傾きについては全く考慮されていない。 However, in the lighting fixture 100 described in Patent Document 1, the positioning of the lamp body 102 with respect to the frame body 101 in the insertion direction, that is, the positioning of the radiation fin 109 in the insertion direction with respect to the first frame portion 103 is considered. However, no consideration is given to the inclination of the lamp body 102 with respect to the insertion direction.
つまり、第１枠部１０３の内周部、つまり段部当接部１０６に沿って灯体１０２を挿入させたときに、仮に灯体１０２の挿入方向に対して放熱フィン１０９が斜めに傾いていると、放熱フィン１０９が段部当接部１０６に引っ掛かり灯体１０２をスムーズに挿入できない。あるいは、挿入できたとしても放熱フィン１０９が傾いたままであると、灯体１０２の回動時に放熱フィン１０９が第１枠部１０３の内周部である段部当接部１０６に引っかかりスムーズに回動させることができず、枠体１０１に対する灯体１０２の取り付け作業が困難になる虞がある。同様の問題は灯体１０２を枠体１０１から取り外す際にも生じる。 That is, when the lamp body 102 is inserted along the inner peripheral portion of the first frame portion 103, that is, the stepped portion contact section 106, the radiating fins 109 are inclined obliquely with respect to the insertion direction of the lamp body 102. If this is the case, the radiating fin 109 is caught by the stepped portion contact portion 106 and the lamp body 102 cannot be inserted smoothly. Alternatively, if the radiating fin 109 remains tilted even if it can be inserted, the radiating fin 109 is caught by the stepped portion contact portion 106 that is the inner peripheral portion of the first frame portion 103 when the lamp body 102 is rotated, and smoothly rotates. It cannot be moved, and there is a possibility that the attaching work of the lamp body 102 to the frame body 101 becomes difficult. A similar problem occurs when the lamp body 102 is removed from the frame body 101.
本発明は、上記問題に鑑みてなされたものであり、枠体に対して灯体を取り付ける際に、より取り付け作業が容易になる照明器具を提供することを目的とする。 The present invention has been made in view of the above problems, and an object of the present invention is to provide a lighting fixture that can be attached more easily when the lamp is attached to the frame.
本発明は、光源を有する灯体と、設置部に取り付けられ、前記灯体を支持する枠体とを備える照明器具であって、前記灯体は、前記枠体に挿入する略円柱状の挿入部と、前記灯体を前記枠体に支持する支持部とを有し、前記枠体は、前記挿入部が挿入される円筒状のガイド部と、中央部に開口を有し前記支持部が載置される円板状の台座部とを有しており、前記台座部は、前記支持部が通過する切欠部を有し、前記ガイド部は、前記切欠部に対し前記灯体の挿入方向側に配置されてあり、前記切欠部を通過した前記支持部の挿入方向の移動を規制する規制部を有することを特徴とする。 The present invention is a lighting fixture including a lamp body having a light source and a frame body that is attached to an installation portion and supports the lamp body, and the lamp body is inserted in a substantially cylindrical shape that is inserted into the frame body.

FIG. 6 is an explanatory diagram of a method for attaching the lamp body 2 to the frame body 1.
図１および図２に示すように、照明器具１０は、枠体１、灯体２、補助反射板３を備える。 As shown in FIGS. 1 and 2, the lighting fixture 10 includes a frame body 1, a lamp body 2, and an auxiliary reflector 3.
図２に示すように、枠体１は、中央に開口４ａを有する円環状の第１枠部４と、同じく中央に開口５ａを有する円環状の第２枠部５と、第１枠部と第２枠部とを接続する複数の接続部１１を有する。 As shown in FIG. 2, the frame 1 includes an annular first frame portion 4 having an opening 4a in the center, an annular second frame portion 5 having an opening 5a in the center, and a first frame portion. A plurality of connection portions 11 for connecting the second frame portion are provided.
第１枠部４と第２枠部５は、図４に示すように、略同心円上に第１枠部４が上方に位置するように配置され、開口４ａ及び開口５ａの開口面に垂直な方向に適長離隔して平行に設けられる。また接続部１１は、第１枠部４と第２枠部５の周方向に沿ってほぼ等間隔に３個所設けられている。各接続部１１の長手方向の両端部は、ねじ４１およびリベット５ｂにより第１枠部４と第２枠部５にそれぞれ固定されている。 As shown in FIG. 4, the first frame portion 4 and the second frame portion 5 are arranged so that the first frame portion 4 is positioned on a substantially concentric circle and is perpendicular to the opening surfaces of the openings 4 a and 5 a. It is provided in parallel with an appropriate distance in the direction. Three connection portions 11 are provided at substantially equal intervals along the circumferential direction of the first frame portion 4 and the second frame portion 5. Both ends in the longitudinal direction of each connection portion 11 are fixed to the first frame portion 4 and the second frame portion 5 by screws 41 and rivets 5b, respectively.
第１枠部４は、中央部に円形の開口４ａを有する円板状の台座部４２、台座部４２の内周部４２ａ近傍から開口４ａの内側上方向に延設された傾斜面を有する円筒状のテーパ部４３と、テーパ部４３の上端部４３ａから略垂直上方に延設された円筒状のガイド部４４を有する。すなわち、テーパ部４３は台座部４２とガイド部４４の間で両部材を連結している。 The first frame portion 4 has a disk-shaped pedestal portion 42 having a circular opening 4a in the center, and a cylinder having an inclined surface extending from the vicinity of the inner peripheral portion 42a of the pedestal portion 42 to the upper side inside the opening 4a. And a cylindrical guide portion 44 extending substantially vertically upward from the upper end portion 43a of the taper portion 43. That is, the taper portion 43 connects both members between the pedestal portion 42 and the guide portion 44.
ガイド部４４は、内径が台座部４２の内周部４２ａの直径よりもわずかに小さい。またテーパ部４３の上端部４３ａ、つまりガイド部４４の下端部は内周部４２ａよりも垂直上方側に位置している。したがって、ガイド部４４の下端部と内周部４２ａを連結するテーパ部４３は、内周部４２ａからガイド部４４側に向かうに従って縮径するように形成され、ガイド部４４および台座部４２に対して傾斜面をなす。なお、第１枠部４には後述する灯体２の円柱状のヒートシンク６が挿入される。 The guide portion 44 has an inner diameter slightly smaller than the diameter of the inner peripheral portion 42 a of the pedestal portion 42. Further, the upper end portion 43a of the taper portion 43, that is, the lower end portion of the guide portion 44 is located vertically above the inner peripheral portion 42a. Therefore, the taper portion 43 that connects the lower end portion of the guide portion 44 and the inner peripheral portion 42 a is formed so as to decrease in diameter from the inner peripheral portion 42 a toward the guide portion 44 side, with respect to the guide portion 44 and the pedestal portion 42. Make an inclined surface. Note that a columnar heat sink 6 of the lamp body 2 described later is inserted into the first frame portion 4.
台座部４２は、内周部４２ａの一部に矩形状に開口したバネ係止部４２ｂが開口４ａを間にして対向する２個所に設けられている。バネ係止部４２ｂには後述のキックバネ８が係止される。また、台座部４２には、接続部１１を固定するねじ４１が挿通される貫通孔が形成されている。 The pedestal portion 42 is provided with two spring engaging portions 42b that are opened in a rectangular shape in a part of the inner peripheral portion 42a and face each other with the opening 4a therebetween. A later-described kick spring 8 is locked to the spring locking portion 42b. The pedestal portion 42 is formed with a through hole through which the screw 41 for fixing the connection portion 11 is inserted.
さらに、台座部４２には、開口４ａを間にして対向する２個所に後述するアーム部７３を挿通されて通過する矩形の切欠部４２ｃが形成されている。切欠部４２ｃは、テーパ部４３を径方向に縦断し、さらにガイド部４４の途中まで延設されている。すなわち切欠部４２ｃは台座部４２とガイド部４４の間に形成された矩形状の貫通孔である。なお、バネ係止部４２ｂ，４２ｂと切欠部４２ｃ，４２ｃは、台座部４２の周方向に略等間隔に設けられている。 Further, the pedestal portion 42 is formed with a rectangular cutout portion 42c that passes through an arm portion 73 described later at two locations facing each other with the opening 4a therebetween. The notch portion 42 c is longitudinally cut in the taper portion 43 in the radial direction, and further extends to the middle of the guide portion 44. That is, the notch portion 42 c is a rectangular through hole formed between the pedestal portion 42 and the guide portion 44. The spring locking portions 42 b and 42 b and the notches 42 c and 42 c are provided at substantially equal intervals in the circumferential direction of the pedestal portion 42.
また、ガイド部４４は切欠部４２ｃに対し灯体２の挿入方向側に位置しており、切欠部４２ｃの上端部、つまりガイド部４４の下端には、切欠部４２ｃに挿入されたアーム部７３の挿入方向の移動を規制する規制部４４ａが形成されている。つまり、切欠部４２ｃに垂直上方向に挿入されたアーム部７３は、規制部４４ａに当接するので、垂直上方向への移動が規制される。 The guide portion 44 is positioned on the insertion direction side of the lamp body 2 with respect to the notch portion 42c, and an arm portion 73 inserted into the notch portion 42c is provided at the upper end portion of the notch portion 42c, that is, the lower end of the guide portion 44. A restricting portion 44a for restricting movement in the insertion direction is formed. That is, the arm portion 73 inserted in the vertically upward direction into the notch portion 42c abuts on the restricting portion 44a, so that the movement in the vertically upward direction is restricted.
また、ガイド部４４およびテーパ部４３には切欠部４２ｃの上端部分に連通し、切欠部４２ｃからガイド部４４およびテーパ部４３の周方向に延設される貫通孔である案内溝４２ｄが形成されている。案内溝４２ｄは、規制部４４ａと台座部４２の内周部４２ａの間に形成される。また案内溝４２ｄは、高さ方向の幅（厚さ寸法）がアーム部７３の高さ方向の幅よりも大きく、アーム部７３が第１枠部４の周方向に沿って案内溝４２ｄ内を移動できるように形成されている。 The guide portion 44 and the taper portion 43 are formed with a guide groove 42d that is a through hole that communicates with the upper end portion of the notch portion 42c and extends in the circumferential direction of the guide portion 44 and the taper portion 43 from the notch portion 42c. ing. The guide groove 42 d is formed between the restricting portion 44 a and the inner peripheral portion 42 a of the pedestal portion 42. Further, the guide groove 42 d has a width in the height direction (thickness dimension) larger than the width in the height direction of the arm portion 73, and the arm portion 73 extends in the guide groove 42 d along the circumferential direction of the first frame portion 4. It is formed so that it can move.
また、案内溝４２ｄの切欠部４２ｃ側の端部には、内周部４２ａから案内溝４２ｄの内側方向に突起する突起部４２ｆが設けられている。つまり、突起部４２ｆは、切欠部４２ｃと、台座部４２におけるアーム部７３の載置位置との間に設けられる。突起部４２ｆの上端と案内溝４２ｄの上端との間には隙間４２ｇが形成されている。隙間４２ｇは、切欠部４２ｃに挿入されたアーム部７３を第１枠部４の周方向に回転させたときに通過できる程度の高さ方向の幅に形成されている。つまり隙間４２ｇの高さ方向の幅はアーム部７３の高さ方向の幅よりもわずかに大きい。 In addition, a protrusion 42f that protrudes from the inner peripheral portion 42a toward the inside of the guide groove 42d is provided at the end of the guide groove 42d on the side of the notch 42c. That is, the projecting portion 42 f is provided between the notch portion 42 c and the mounting position of the arm portion 73 in the pedestal portion 42. A gap 42g is formed between the upper end of the protrusion 42f and the upper end of the guide groove 42d. The gap 42g is formed with a width in the height direction so that the arm portion 73 inserted into the cutout portion 42c can pass when the arm portion 73 is rotated in the circumferential direction of the first frame portion 4. That is, the width of the gap 42g in the height direction is slightly larger than the width of the arm portion 73 in the height direction.
次に、第２枠部５は、中央部に開口５ａを有する円板状の化粧枠５１と、化粧枠５１の内周部５１ａから垂直上方に延設された円筒部５２とを有する。化粧枠５１は、照明器具１０を天井に設けられた埋め込み孔（不図示）に挿入して取り付けたときに、上記埋め込み孔の周縁を覆い天井面に当接する。円筒部５２には、リベット５ｂにより接続部１１の下端部が取り付けられる。 Next, the second frame portion 5 includes a disk-shaped decorative frame 51 having an opening 5 a at the center, and a cylindrical portion 52 extending vertically upward from the inner peripheral portion 51 a of the decorative frame 51. The decorative frame 51 covers the periphery of the embedded hole and abuts the ceiling surface when the lighting fixture 10 is inserted and attached to an embedded hole (not shown) provided in the ceiling. A lower end portion of the connection portion 11 is attached to the cylindrical portion 52 by a rivet 5b.
図４に示す接続部１１は、矩形状の板部材であり、第１枠部４の台座部４２と第２枠部５の円筒部５２に固定される。具体的には、接続部１１の上端部に先端がＬ字状に屈曲した屈曲部１１ａを有し、屈曲部１１ａに設けられたねじ穴とねじ４１により屈曲部１１ａが台座部４２に固定される。また、接続部１１の下端部の設けられた貫通孔とリベット５ｂにより上記下端部が円筒部５２に固定される。また、接続部１１の中央部には長手方向に延びるスリット１２が形成されており、スリット１２に図１および図３に示すように公知の取付金具１３が取り付けられている。取付金具１３と化粧枠５１との間に天井面を挟持することにより照明器具１０を天井に設けられた埋め込み孔に取り付けることができる。 The connection part 11 shown in FIG. 4 is a rectangular plate member, and is fixed to the pedestal part 42 of the first frame part 4 and the cylindrical part 52 of the second frame part 5. Specifically, the upper end portion of the connecting portion 11 has a bent portion 11a whose tip is bent in an L shape, and the bent portion 11a is fixed to the pedestal portion 42 by a screw hole and a screw 41 provided in the bent portion 11a. The Further, the lower end portion is fixed to the cylindrical portion 52 by the through hole provided at the lower end portion of the connection portion 11 and the rivet 5b. A slit 12 extending in the longitudinal direction is formed at the center of the connecting portion 11, and a known mounting bracket 13 is attached to the slit 12 as shown in FIGS. 1 and 3. By holding the ceiling surface between the mounting bracket 13 and the decorative frame 51, the lighting fixture 10 can be attached to the embedded hole provided in the ceiling.
次に、図５に示す灯体２について説明する。灯体２は、ヒートシンク６と、灯具本体７を有する。 Next, the lamp body 2 shown in FIG. 5 will be described. The lamp body 2 includes a heat sink 6 and a lamp body 7.
ヒートシンク６は、アルミニウム等の金属製材料からなり、押出し成型により形成される外形が円柱状をなす部材である。ヒートシンク６は、枠体１に挿入する挿入部である。ヒートシンク６は、中実の軸部６１と軸部６１の外周面から径方向に延設され、軸部６１の周方向に沿って複数設けられた放熱フィン６２を有する。複数の放熱フィン６２の側面により形成されるヒートシンク６の外周面６３はほぼ円柱の外周面をなすように形成されている。外周面６３の直径はガイド部４４の内径よりわずかに小さい寸法に形成されている。 The heat sink 6 is a member made of a metal material such as aluminum and having an outer shape formed by extrusion forming a cylindrical shape. The heat sink 6 is an insertion portion that is inserted into the frame body 1. The heat sink 6 includes a solid shaft portion 61 and a plurality of heat dissipating fins 62 extending in the radial direction from the outer peripheral surface of the shaft portion 61 and provided along the circumferential direction of the shaft portion 61. The outer peripheral surface 63 of the heat sink 6 formed by the side surfaces of the plurality of radiating fins 62 is formed so as to form a substantially cylindrical outer peripheral surface. The diameter of the outer peripheral surface 63 is formed to be slightly smaller than the inner diameter of the guide portion 44.
軸部６１の不図示の下面部には光源であるＬＥＤ（不図示）が実装されており、ＬＥＤからの熱が上記下面部から軸部６１を介して放熱フィン６２に伝導され、放熱フィン６２からＬＥＤの熱を外部に放熱することができる。 An LED (not shown), which is a light source, is mounted on a lower surface portion (not shown) of the shaft portion 61, and heat from the LED is conducted from the lower surface portion to the heat radiation fin 62 via the shaft portion 61. The heat of the LED can be radiated to the outside.
灯具本体７は、光源としてのＬＥＤを収容する筒状の金属部材であり、ヒートシンク６とは別体に構成されている。なお、灯具本体７とヒートシンク６とは不図示のねじにより固定されている。灯具本体７は、円錐台状の本体部７１、本体部７１から連接された筒部７２、本体部７１から側方に突出して設けられた矩形状のアーム部７３を有する。アーム部７３は灯体２を枠体１に支持する支持部である。アーム部７３は灯体２が有するヒートシンク６の外周面６３よりも外側に突出している。なお、本実施形態では、アーム部７３は灯具本体７に設けられているが、ヒートシンク６に支持部としてのアーム部を設けてもよい。 The lamp body 7 is a cylindrical metal member that accommodates an LED as a light source, and is configured separately from the heat sink 6. The lamp body 7 and the heat sink 6 are fixed by screws (not shown). The lamp body 7 includes a truncated cone-shaped main body portion 71, a cylindrical portion 72 connected to the main body portion 71, and a rectangular arm portion 73 provided so as to protrude laterally from the main body portion 71. The arm portion 73 is a support portion that supports the lamp body 2 on the frame body 1. The arm portion 73 projects outward from the outer peripheral surface 63 of the heat sink 6 included in the lamp body 2. In this embodiment, the arm portion 73 is provided on the lamp body 7, but an arm portion as a support portion may be provided on the heat sink 6.
筒部７２の下面にはガラス製の透光部７４が設けられており、透光部７４からＬＥＤの光を出射する。なお、本体部７１の不図示の内面はＬＥＤからの光を反射する反射面を形成する。 A light transmitting portion 74 made of glass is provided on the lower surface of the cylindrical portion 72, and LED light is emitted from the light transmitting portion 74. The inner surface (not shown) of the main body 71 forms a reflection surface that reflects light from the LED.
アーム部７３は、台座部４２の上面に載置されることで灯体２を枠体１に支持する部材である。具体的には、アーム部７３は、台座部４２の上面における切欠部４２ｃに隣接する位置であり、かつ案内溝４２ｄに対向する面（案内溝４２ｄの径方向外側に位置する面）に載置される（図１参照）。そして、図４に示す台座部４２に設けられたねじ孔４２ｅの位置で、ねじ孔４２ｅに下面側から挿入された固定部材としてのローレットビス４５によりアーム部７３が固定される。なお、ローレットビス４５は台座部４２から落下しないようにねじ孔４２ｅに予め保持されており、先端部がねじ孔４２ｅから突出している。 The arm portion 73 is a member that supports the lamp body 2 to the frame body 1 by being placed on the upper surface of the pedestal portion 42. Specifically, the arm portion 73 is placed on a surface adjacent to the notch portion 42c on the upper surface of the pedestal portion 42 and facing the guide groove 42d (a surface located on the radially outer side of the guide groove 42d). (See FIG. 1). And the arm part 73 is fixed by the position of the screw hole 42e provided in the base part 42 shown in FIG. 4 with the knurled screw 45 as a fixing member inserted into the screw hole 42e from the lower surface side. The knurled screw 45 is held in advance in the screw hole 42e so as not to fall from the pedestal portion 42, and the tip portion protrudes from the screw hole 42e.
アーム部７３は本体部７１を間にして対向する２個所に本体部７１と一体的に設けられており、２個所のアーム部７３で灯体２を枠体１に支持できる強度を有している。アーム部７３の下面には台座部４２から突出するローレットビス４５を案内する溝状の案内部７３ａと、案内部７３ａの端部に設けられローレットビス４５が挿通する貫通孔７３ｂを有する。 The arm portion 73 is provided integrally with the main body portion 71 at two locations facing each other with the main body portion 71 therebetween, and has strength that can support the lamp body 2 on the frame body 1 by the two arm portions 73. Yes. The lower surface of the arm portion 73 has a groove-shaped guide portion 73a that guides the knurled screw 45 protruding from the pedestal portion 42, and a through hole 73b that is provided at an end portion of the guide portion 73a and through which the knurled screw 45 is inserted.
次に、図２に示す補助反射板３は、枠体１の化粧枠５１の内側に鏡面加工された反射面を形成する下方に向かって拡径した筒状の部材であり、上端３１に取り付けられたＶ字状のキックバネ８により枠体１に保持される。具体的には、枠体１および灯体２が天井に設けられた埋め込み孔に取り付けられた状態で、キックバネ８を台座部４２のバネ係止部４２ｂに挿通し、キックバネ８により上方に作用する付勢力で補助反射板３下端に位置する枠部３２が化粧枠５１の下面に係止する。このようにして、キックバネ８の作用により補助反射板３が枠体１に取り付けられる。 Next, the auxiliary reflecting plate 3 shown in FIG. 2 is a cylindrical member whose diameter is expanded downward to form a mirror-finished reflecting surface inside the decorative frame 51 of the frame 1, and is attached to the upper end 31. The V-shaped kick spring 8 is held by the frame 1. Specifically, in a state where the frame 1 and the lamp body 2 are attached to the embedding hole provided in the ceiling, the kick spring 8 is inserted into the spring locking portion 42b of the pedestal portion 42 and acts upward by the kick spring 8. The frame portion 32 positioned at the lower end of the auxiliary reflector 3 is locked to the lower surface of the decorative frame 51 by the urging force. In this way, the auxiliary reflector 3 is attached to the frame 1 by the action of the kick spring 8.
次に、照明器具１０の取り付け手順について図２および図６を用いて説明する。 Next, the attachment procedure of the lighting fixture 10 is demonstrated using FIG. 2 and FIG.
まず、枠体１を天井等に設けられた埋め込み孔に第１枠部４側から図２の矢印Ａに示す方向に挿入し、第２枠部５の化粧枠５１の上面を天井面における埋め込み孔の周囲の部分に当接させる。３個所の接続部１１に取り付けられた取付金具１３は、化粧枠５１が天井面に当接するときに埋め込み孔よりも外側に突出する。これにより、取付金具１３と化粧枠５１の間に天井面が狭持され、枠体１が天井に保持される。 First, the frame 1 is inserted into an embedding hole provided in the ceiling or the like in the direction indicated by the arrow A in FIG. 2 from the first frame 4 side, and the upper surface of the decorative frame 51 of the second frame 5 is embedded in the ceiling surface. It abuts on the peripheral part of the hole. The attachment fittings 13 attached to the three connection portions 11 protrude outward from the embedding hole when the decorative frame 51 comes into contact with the ceiling surface. Thereby, a ceiling surface is pinched between the attachment metal fitting 13 and the decorative frame 51, and the frame 1 is hold | maintained on a ceiling.
次に、灯体２をヒートシンク６側から第２枠部５の開口５ａの下方側から同じく矢印Ａの方向に挿入する。このとき、灯体２のアーム部７３の位置を第１枠部４の切欠部４２ｃの位置に合わせて挿入する。切欠部４２ｃの位置は、灯体２の挿入時に天井面の下方から確認することが可能である。 Next, the lamp body 2 is inserted in the direction of arrow A from the lower side of the opening 5a of the second frame portion 5 from the heat sink 6 side. At this time, the position of the arm part 73 of the lamp body 2 is inserted in accordance with the position of the notch part 42 c of the first frame part 4. The position of the notch 42c can be confirmed from below the ceiling surface when the lamp body 2 is inserted.
灯体２のアーム部７３が第２枠部５を通過し、さらに第１枠部４の切欠部４２ｃに挿入され切欠部４２ｃを通過すると、アーム部７３の上面がガイド部４４の規制部４４ａに当接し、図６の（ａ）で示される状態になる。このとき、作業者は灯体２を枠体１に対して回転させる位置であることがわかる。 When the arm part 73 of the lamp body 2 passes through the second frame part 5 and is further inserted into the notch part 42c of the first frame part 4 and passes through the notch part 42c, the upper surface of the arm part 73 becomes the regulating part 44a of the guide part 44. To a state shown in FIG. At this time, it can be seen that the operator is in a position to rotate the lamp body 2 with respect to the frame body 1.
次に、アーム部７３が規制部４４ａに位置した状態で灯体２を作業者側から見て時計回り、つまり図６（ａ）の矢印Ｂで示す案内溝４２ｄが延びる方向に回動させる。アーム部７３は、まず切欠部４２ｃの上端からガイド部４４の周方向に連接された隙間４２ｇを通過する。アーム部７３の回転方向と反対側の端部が隙間４２ｇを通過すると、アーム部７３の回転方向側の端部が案内溝４２ｄの回転方向側の端部４２ｄ１に当接する。このとき、図６の（ｂ）で示される状態になり、作業者はアーム部７３を枠体１の台座部４２に載置する位置であることがわかる。 Next, the lamp body 2 is rotated clockwise as viewed from the operator side with the arm portion 73 positioned at the restricting portion 44a, that is, in the direction in which the guide groove 42d indicated by the arrow B in FIG. The arm portion 73 first passes through the gap 42g connected in the circumferential direction of the guide portion 44 from the upper end of the notch portion 42c. When the end portion on the opposite side to the rotation direction of the arm portion 73 passes through the gap 42g, the end portion on the rotation direction side of the arm portion 73 comes into contact with the end portion 42d1 on the rotation direction side of the guide groove 42d. At this time, the state shown in FIG. 6B is obtained, and it is understood that the operator is in a position to place the arm portion 73 on the pedestal portion 42 of the frame body 1.
次に、灯体２のアーム部７３を台座部４２に載置し、２個所のアーム部７３の貫通孔７３ｂに台座部４２から突出したローレットビス４５を締結することで、アーム部７３は台座部４２に固定され、これにより枠体１に灯体２が固定される。このとき、アーム部７３の回転方向と反対側の位置、つまりアーム部７３の載置位置と切欠部４２ｃとの間には台座部４２から上方向に突起する突起部４２ｆが位置する。台座部４２に載置されたアーム部７３が固定される前であっても、突起部４２ｆによりアーム部７３が切欠部４２ｃ側に移動することを規制することができるので、取り付け作業時における灯体２の落下を防止することができる。 Next, the arm portion 73 of the lamp body 2 is placed on the pedestal portion 42, and the knurled screw 45 projecting from the pedestal portion 42 is fastened to the through holes 73 b of the two arm portions 73, so that the arm portion 73 becomes the pedestal. The lamp body 2 is fixed to the frame body 1 by being fixed to the portion 42. At this time, a protruding portion 42f protruding upward from the pedestal portion 42 is located at a position opposite to the rotation direction of the arm portion 73, that is, between the mounting position of the arm portion 73 and the notch portion 42c. Even before the arm portion 73 placed on the pedestal portion 42 is fixed, it is possible to restrict the movement of the arm portion 73 toward the cutout portion 42c by the projection 42f. The fall of the body 2 can be prevented.
最後に、補助反射板３に取り付けられたキックバネ８を、キックバネ８の両端部が近づく方向に縮めてバネ係止部４２ｂに挿入する。補助反射板３を枠体１の方向に挿入するに従って、キックバネ８が広がり、補助反射板３を垂直上方向に付勢する力により補助反射板３の枠部３２が化粧枠５１の下面に係止して補助反射板３が枠体１に取り付けられる。以上の手順により照明器具１０の取り付け作業を完了する。 Finally, the kick spring 8 attached to the auxiliary reflector 3 is contracted in the direction in which both ends of the kick spring 8 approach each other and inserted into the spring locking portion 42b. As the auxiliary reflecting plate 3 is inserted in the direction of the frame 1, the kick spring 8 is expanded, and the frame portion 32 of the auxiliary reflecting plate 3 is engaged with the lower surface of the decorative frame 51 by the force that urges the auxiliary reflecting plate 3 vertically upward. Then, the auxiliary reflector 3 is attached to the frame 1. The attachment work of the lighting fixture 10 is completed by the above procedure.
以上の取り付け手順において、灯体２を枠体１に挿入するときにヒートシンク６の外周面６３がガイド部４４の内周面と面接触可能に挿入できるため、灯体２を枠体１に対し確実に垂直方向に挿入することが可能となる。すなわち、灯体２の挿入方向（垂直方向）に対して灯体２が斜めに傾きにくくすることができるので、図７の従来の照明器具１００のように灯体１０２の挿入時に放熱フィン１０９が枠体１０１に引っ掛かり、挿入作業がしにくくなることを防止できる。 In the above attachment procedure, when the lamp body 2 is inserted into the frame body 1, the outer peripheral surface 63 of the heat sink 6 can be inserted so as to come into surface contact with the inner peripheral surface of the guide portion 44. It becomes possible to insert in the vertical direction with certainty. That is, since the lamp body 2 can be made difficult to be inclined obliquely with respect to the insertion direction (vertical direction) of the lamp body 2, when the lamp body 102 is inserted, the heat dissipating fins 109 are provided when the lamp body 102 is inserted as in the conventional lighting fixture 100 of FIG. It is possible to prevent the frame 101 from being caught and difficult to perform the insertion work.
さらに、外周面６３とガイド部４４の内周面は、面同士が互いに対向しているので、灯体２を枠体１への挿入後に回動させる際にも灯体２が斜め傾きにくく、したがって放熱フィン６２がガイド部４４の内面に引っ掛からずにスムーズに灯体２を回転させることができる。 Furthermore, since the outer peripheral surface 63 and the inner peripheral surface of the guide portion 44 face each other, the lamp body 2 is not easily inclined obliquely when the lamp body 2 is rotated after being inserted into the frame body 1. Therefore, the lamp body 2 can be smoothly rotated without the radiating fin 62 being caught on the inner surface of the guide portion 44.
また、ガイド部４４と台座部４２との間にテーパ部４３が形成されているので、外周面６３より内径が大きい台座部４２の内周部４２ａからテーパ部４３の傾斜面に沿ってガイド部４４側にヒートシンク６を案内しながら挿入することができる。これにより、外周面６３の直径とガイド部４４の内径の差がわずかであっても、スムーズにヒートシンク６をガイド部４４に挿入することができる。 Further, since the tapered portion 43 is formed between the guide portion 44 and the pedestal portion 42, the guide portion extends along the inclined surface of the tapered portion 43 from the inner peripheral portion 42 a of the pedestal portion 42 having an inner diameter larger than the outer peripheral surface 63. The heat sink 6 can be inserted into the 44 side while being guided. Thereby, even if the difference between the diameter of the outer peripheral surface 63 and the inner diameter of the guide portion 44 is small, the heat sink 6 can be smoothly inserted into the guide portion 44.
また、ローレットビス４５は台座部４２から落下しないようにねじ孔４２ｅに予め保持されており、先端がねじ孔４２ｅから突出している。この状態で灯体２とともに回動するアーム部７３の案内部７３ａに沿ってローレットビス４５の先端部が案内される。これにより、スムーズにローレットビス４５をアーム部７３の側面部から固定位置である貫通孔７３ｂまで案内することができる。 Further, the knurled screw 45 is held in advance in the screw hole 42e so as not to fall from the pedestal portion 42, and the tip protrudes from the screw hole 42e. In this state, the tip of the knurled screw 45 is guided along the guide portion 73 a of the arm portion 73 that rotates together with the lamp body 2. Thereby, the knurled screw 45 can be smoothly guided from the side surface portion of the arm portion 73 to the through hole 73b which is a fixed position.
また、図７に示した従来の照明器具１００では、受部１０７が、第１枠部本体１１０の一部を切り欠いて片持ち状に突出するように形成された係止部１０８に載置されているのに対し、本発明のアーム部７３は、円板状の台座部４２に直接載置できるので、強度的により安定して灯体２を枠体１に保持することができる。 Further, in the conventional lighting apparatus 100 shown in FIG. 7, the receiving portion 107 is placed on the locking portion 108 formed so as to project a cantilever shape by cutting out a part of the first frame main body 110. On the other hand, the arm portion 73 of the present invention can be directly placed on the disk-like pedestal portion 42, so that the lamp body 2 can be held on the frame body 1 more stably in strength.
また、従来の照明器具１００が、挿入方向の位置決めのために放熱フィン１０９から段部１０５を形成しており、放熱フィン１０９の直径が大きくなることで灯体１０２が大型化し重量も大きくなるのに対し、本発明は、アーム部７３を利用して挿入方向の位置決めをしており、さらにアーム部７３が当接する規制部４４ａをガイド部４４と一体的に設けているので、垂直方向の位置決めのために灯具２および枠体１を大型化する必要がない。 Moreover, the conventional lighting fixture 100 forms the step part 105 from the radiation fin 109 for positioning in the insertion direction, and the lamp body 102 is increased in size and weight by increasing the diameter of the radiation fin 109. In contrast, in the present invention, the arm portion 73 is used for positioning in the insertion direction, and the restricting portion 44a with which the arm portion 73 abuts is provided integrally with the guide portion 44. Therefore, the positioning in the vertical direction is performed. Therefore, it is not necessary to increase the size of the lamp 2 and the frame 1.
以上の実施の形態の説明において、光源としてＬＥＤを用いる例について説明したが、光源はＬＥＤに限定されず、ＥＬや蛍光ランプ等の他の光源を用いてもよい。また、一実施形態としてダウンライトに適用する例について説明したが、枠体および枠体に挿入して取り付ける灯体を備える照明器具であれば照明器具の形態や設置位置等は特に限定されない。 In the above description of the embodiment, the example in which the LED is used as the light source has been described. Moreover, although the example applied to a downlight was demonstrated as one Embodiment, if it is a lighting fixture provided with the lamp body inserted into the frame body and a frame body, the form, installation position, etc. of a lighting fixture will not be specifically limited.
