Is provided.

図示していないが、ＬＥＤモジュールは、複数のＬＥＤと、正方形状であり、複数のＬＥＤが実装された基板とからなる。ＬＥＤモジュールは、モジュール取り付け部４１０にネジにより固定されているが、接着等により固定されてもよい。本実施の形態では、ＬＥＤモジュールがモジュール取り付け部４１０に４つ取り付けられている。なお、ＬＥＤモジュールを大きく構成して１つにしてもよいし、４つ以上に細かく分割してもよい。基板としては、正方形状のものに限らず、長方形状又はその他の形状に形成されたものが並べられてもよい。 Although not shown, the LED module includes a plurality of LEDs and a square-shaped substrate on which the plurality of LEDs are mounted. The LED module is fixed to the module mounting portion 410 with screws, but may be fixed by bonding or the like. In the present embodiment, four LED modules are attached to module attaching section 410. The LED module may be configured to be large and may be one, or may be finely divided into four or more. The substrate is not limited to a square substrate, and may be a substrate formed in a rectangular shape or another shape.

モジュール取り付け部４１０は、ＬＥＤモジュールが取り付けられている取り付け正面部４１１と、取り付け正面部４１１の外周部に平面視で「ロ」の字状に設けられ、カバー部の端部が挿し込まれているカバー受け部４１２とで構成される。 The module mounting section 410 is provided in a mounting front section 411 to which the LED module is mounted, and is provided in an outer peripheral portion of the mounting front section 411 in a rectangular shape in plan view, and the end of the cover section is inserted. Cover receiving portion 412.

取り付け正面部４１１は、四角形の板状であり、一方の面である光源設置面には４つのＬＥＤモジュールが配置され、他方の面である点灯装置設置面３０２には１対の点灯装置４２０、１対の穴開き部材２３０、１対の引っ掛け部材２４０が配列されている。点灯装置４２０は、点灯装置設置面３０２の中央付近に長手方向の側面が対向するように並行する状態で２つ設置されている。穴開き部材２３０と引っ掛け部材２４０は、点灯装置４２０に対して点灯装置４２０の長手方向の側面が対向するカバー受け部４１２に寄った状態において点灯装置４２０の短手方向の側面に対向するカバー受け部４１２にそれぞれ寄って配置されている。引っ掛け部材２４０は、先端がカバー受け部４１２より外側に突き出すようにスライド可能である。 The mounting front portion 411 has a rectangular plate shape, and four LED modules are arranged on a light source installation surface, which is one surface, and a pair of lighting devices 420, on a lighting device installation surface 302, which is another surface. A pair of perforated members 230 and a pair of hook members 240 are arranged. Two lighting devices 420 are installed near the center of the lighting device installation surface 302 in a state where the side surfaces in the longitudinal direction face each other in parallel. The perforated member 230 and the hooking member 240 are arranged so that the cover receiving member 412 faces the short side surface of the lighting device 420 in a state where the longitudinal side surface of the lighting device 420 is close to the cover receiving portion 412 facing the lighting device 420. The parts 412 are arranged closer to each other. The hook member 240 is slidable so that the tip protrudes outside the cover receiving portion 412.

上記のように、取り付け正面部４１１には、光源が設置される光源設置面と、光源設置面の反対の面であり、かつ、器具本体１０１の端子台設置面１０２に対向する面であり、長手状の点灯装置４２０が設置される点灯装置設置面３０２とが形成されている。即ち、光源ユニット３００は、光源設置面と、点灯装置設置面３０２とを有する。点灯装置４２０は、器具本体１０１の端子台１３０を介して給電されることで光源を点灯させる。 As described above, the mounting front part 411 is a surface opposite to the light source installation surface on which the light source is installed and the light source installation surface, and is a surface facing the terminal block installation surface 102 of the appliance main body 101; The lighting device installation surface 302 on which the elongated lighting device 420 is installed is formed. That is, the light source unit 300 has a light source installation surface and a lighting device installation surface 302. The lighting device 420 lights the light source by being supplied with power through the terminal block 130 of the appliance main body 101.

穴開き部材２３０には、バネ部材２１０の円弧部２１１が挿し込まれる穴が形成されている。光源ユニット３００が仮保持されるときは、この穴にバネ部材２１０の先端部２１３が引っ掛けられる。光源ユニット３００が仮保持状態から装着状態に移行する過程では、穴開き部材２３０の穴に対してバネ部材２１０の円弧部２１１が摺動する。穴開き部材２３０は、バネ部材２１０に対応するように取り付け正面部４１１に２つ並列に配置されている。 The hole 230 is formed with a hole into which the arc portion 211 of the spring member 210 is inserted. When the light source unit 300 is temporarily held, the tip 213 of the spring member 210 is hooked on this hole. In the process of shifting the light source unit 300 from the temporary holding state to the mounting state, the arc portion 211 of the spring member 210 slides with respect to the hole of the perforated member 230. Two perforated members 230 are arranged in parallel on the mounting front part 411 so as to correspond to the spring members 210.

引っ掛け部材２４０は、爪付き部材２２０の爪２２１に引っ掛けられるものであり、爪付き部材２２０に対応するように取り付け正面部４１１に２つ並列に配置されている。 The hook members 240 are hooked on the claws 221 of the claw member 220, and two hook members 240 are arranged in parallel on the mounting front portion 411 so as to correspond to the claw members 220.

引っ掛け部材２４０は、モジュール取り付け部４１０の取り付け正面部４１１を切り起こして形成された溝部にスライド可能に保持されているとともに、摺動部材２５０及び押さえ部材２６０に装着されている。摺動部材２５０及び押さえ部材２６０は、引っ掛け部材２４０が前後方向にスライドするのに伴い、引っ掛け部材２４０を斜め方向へ誘導する。 The hooking member 240 is slidably held in a groove formed by cutting and raising the mounting front part 411 of the module mounting part 410, and is attached to the sliding member 250 and the pressing member 260. The sliding member 250 and the pressing member 260 guide the hooking member 240 in an oblique direction as the hooking member 240 slides in the front-back direction.

引っ掛け部材２４０が前方にスライドする過程において、引っ掛け部材２４０の先端部は、押さえ部材２６０がある位置から引き出されて、取り付け正面部４１１から徐々に遠ざかる。引っ掛け部材２４０の先端部よりも後ろの部分は、摺動部材２５０と押さえ部材２６０との間に形成される隙間の中で前方かつ斜め上方にスライドする。このとき、引っ掛け部材２４０の後端部は、押さえ部材２６０によって押さえ付けられる。 In the process in which the hooking member 240 slides forward, the distal end of the hooking member 240 is pulled out from the position where the holding member 260 is located, and gradually moves away from the mounting front portion 411. The portion of the hook member 240 behind the distal end slides forward and diagonally upward in a gap formed between the sliding member 250 and the pressing member 260. At this time, the rear end of the hooking member 240 is pressed by the pressing member 260.

引っ掛け部材２４０が前方にスライドすることで、引っ掛け部材２４０の先端部は、光源ユニット３００の平面視における外郭よりも外側に突き出している状態になる。引っ掛け部材２４０の先端部と後端部との間の部分は、押さえ部材２６０の前方かつ斜め上方に位置している状態になる。引っ掛け部材２４０の後端部は、摺動部材２５０と押さえ部材２６０とによって押圧されている状態になる。このため、引っ掛け部材２４０が、前後方向及び上下方向において固定され、引き出された状態を維持することができる。また、引っ掛け部材２４０がスライドすることで、引っ掛け部材２４０の後端部が、押さえ部材２６０に引っ掛かっている状態になる。このため、引っ掛け部材２４０が必要以上に手前に引き出されることが防止される。 When the hooking member 240 slides forward, the distal end portion of the hooking member 240 is in a state of protruding outside the outer contour of the light source unit 300 in plan view. The portion between the leading end and the trailing end of the hooking member 240 is located in front of and obliquely above the pressing member 260. The rear end of the hooking member 240 is pressed by the sliding member 250 and the pressing member 260. For this reason, the hooking member 240 is fixed in the front-rear direction and the up-down direction, and can maintain the pulled-out state. When the hooking member 240 slides, the rear end of the hooking member 240 is hooked on the pressing member 260. Therefore, the hook member 240 is prevented from being pulled out more than necessary.

引っ掛け部材２４０が後方にスライドする過程において、引っ掛け部材２４０の先端部は、光源ユニット３００の平面視における外郭よりも外側の位置から押し込まれて、取り付け正面部４１１に徐々に近づく。引っ掛け部材２４０の先端部よりも後ろの部分は、摺動部材２５０と押さえ部材２６０との間に形成される隙間の中で後方かつ斜め下方にスライドする。このとき、引っ掛け部材２４０の後端部は、押さえ部材２６０によって押さえ付けられる。 In the process in which the hooking member 240 slides backward, the distal end of the hooking member 240 is pushed in from a position outside the outer shell of the light source unit 300 in plan view, and gradually approaches the mounting front portion 411. The portion of the hook member 240 behind the distal end slides obliquely downward and rearward in a gap formed between the sliding member 250 and the pressing member 260. At this time, the rear end of the hooking member 240 is pressed by the pressing member 260.

光源ユニット３００を器具本体１０１に取り付ける際には、まず、引っ掛け部材２４０を摺動部材２５０に沿って引き出し、引っ掛け部材２４０の先端部をカバー受け部４１２より外側に突き出させる。このとき、引っ掛け部材２４０の先端部と取り付け正面部４１１との距離が広がる。つまり、引っ掛け部材２４０は、垂直方向及び水平方向の両方において引っ掛け部材２４０の先端部と取り付け正面部４１１との距離が広がるように引き出される。 When attaching the light source unit 300 to the instrument main body 101, first, the hooking member 240 is pulled out along the sliding member 250, and the tip of the hooking member 240 is protruded outward from the cover receiving portion 412. At this time, the distance between the distal end of the hook member 240 and the mounting front 411 increases. That is, the hook member 240 is pulled out so that the distance between the tip end of the hook member 240 and the mounting front portion 411 increases in both the vertical direction and the horizontal direction.

次に、引っ掛け部材２４０が引き出された状態で、光源ユニット３００をほぼ垂直に傾け、爪付き部材２２０の爪２２１に引っ掛け部材２４０を引っ掛ける。前述したように、引っ掛け部材２４０は、引き出された状態では、摺動部材２５０と押さえ部材２６０とにより前後方向及び上下方向において固定される。また、引っ掛け部材２４０の後端部が押さえ部材２６０に引っ掛かる。これにより、光源ユニット３００が仮保持状態になる。この状態において、端子台１３０のコネクタと点灯装置４２０のコネクタとの間を電線で接続する。引っ掛け部材２４０の先端部と爪付き部材２２０の爪２２１は、光源ユニット３００の回転軸を形成する。 Next, in a state where the hook member 240 is pulled out, the light source unit 300 is tilted substantially vertically, and the hook member 240 is hooked on the claw 221 of the claw member 220. As described above, the hooking member 240 is fixed in the front-rear direction and the vertical direction by the sliding member 250 and the pressing member 260 when pulled out. Further, the rear end of the hooking member 240 is hooked on the pressing member 260. As a result, the light source unit 300 enters a temporary holding state. In this state, the connector of the terminal block 130 and the connector of the lighting device 420 are connected by an electric wire. The tip of the hook member 240 and the claw 221 of the claw member 220 form a rotation axis of the light source unit 300.

次に、光源ユニット３００をほぼ垂直な状態から回転させるとともに、バネ部材２１０を弾性変形させてバネ部材２１０の先端部２１３を穴開き部材２３０の穴に引っ掛ける。 Next, the light source unit 300 is rotated from a substantially vertical state, and at the same time, the spring member 210 is elastically deformed so that the distal end portion 213 of the spring member 210 is hooked on the hole of the perforated member 230.

最後に、光源ユニット３００を器具本体１０１に向かって押し上げることで、引っ掛け部材２４０の先端部が爪付き部材２２０の係止部２２２に押し込まれる。これにより、光源ユニット３００の引っ掛け部材２４０がある側が引き上げられていく。また、バネ部材２１０の円弧部２１１が穴開き部材２３０の穴の縁を摺動する。これにより、光源ユニット３００の穴開き部材２３０がある側が引き上げられていく。光源ユニット３００が完全に引き上げられると、光源ユニット３００が器具本体１０１の開口を閉塞し、器具本体１０１に固定される。このとき、引っ掛け部材２４０は、押さえ部材２６０により前後方向及び上下方向において固定される。 Finally, by pushing up the light source unit 300 toward the instrument main body 101, the distal end of the hooking member 240 is pushed into the locking portion 222 of the claw member 220. Thereby, the side of the light source unit 300 where the hook member 240 is located is raised. Further, the arc portion 211 of the spring member 210 slides along the edge of the hole of the perforated member 230. Thus, the side of the light source unit 300 where the perforated member 230 is located is raised. When the light source unit 300 is completely pulled up, the light source unit 300 closes the opening of the instrument body 101 and is fixed to the instrument body 101. At this time, the hooking member 240 is fixed in the front-rear direction and the vertical direction by the pressing member 260.

図４を参照して、照明装置８００の構成の詳細を説明する。図４は、照明装置８００の一部の断面を示した図である。 With reference to FIG. 4, the details of the configuration of lighting device 800 will be described. FIG. 4 is a diagram showing a partial cross section of the lighting device 800.

器具本体１０１は、天井材９００に形成された埋め込み穴に埋め込まれている。器具本体１０１は、埋め込み穴の奥に設けられたボルト等の固定具が挿入孔１１２に挿通されている状態で固定されている。鍔部１４０は、天井材９００と同じ高さに位置するように形成されている。枠部１５０は、少なくとも一部が天井材９００の下方、即ち、埋め込み穴の外側に位置するように形成されている。 The appliance main body 101 is embedded in an embedding hole formed in the ceiling material 900. The device main body 101 is fixed in a state where a fixing tool such as a bolt provided at the back of the embedding hole is inserted into the insertion hole 112. The flange 140 is formed so as to be located at the same height as the ceiling material 900. The frame 150 is formed so that at least a part thereof is located below the ceiling material 900, that is, outside the embedding hole.

光源ユニット３００は、一部が器具本体１０１よりも側方にはみ出してはみ出し部３１０を形成している。 A part of the light source unit 300 protrudes laterally from the appliance body 101 to form a protruding portion 310.

鍔部１４０は、器具本体１０１から、はみ出し部３１０がはみ出している方向Ｄ０に延び、器具本体１０１に近い側の端部１４２がはみ出し部３１０と当たることで光源ユニット３００を受けている。はみ出し部３１０がはみ出している方向Ｄ０とは、本体部１００の側方のことである。 The flange 140 extends in the direction D0 in which the protruding portion 310 protrudes from the appliance main body 101, and receives the light source unit 300 when the end 142 closer to the appliance main body 101 contacts the protruding portion 310. The direction D <b> 0 in which the protruding portion 310 protrudes is a side of the main body 100.

枠部１５０は、鍔部１４０の器具本体１０１から遠い側の端部１４３から、光源ユニット３００と離れた状態で器具本体１０１から光源ユニット３００へ向かう方向Ｄ１に延びている。器具本体１０１から光源ユニット３００へ向かう方向Ｄ１とは、本体部１００の器具本体１０１がある側Ｓ１から光源ユニット３００がある側Ｓ２へ向かう方向のことである。 The frame 150 extends from the end 143 of the flange 140 farther from the instrument body 101 in a direction D1 from the instrument body 101 toward the light source unit 300 in a state separated from the light source unit 300. The direction D1 from the appliance main body 101 toward the light source unit 300 is a direction from the side S1 of the main body 100 where the appliance main body 101 is located to the side S2 where the light source unit 300 is located.

照明装置８００が上記のような構成になっていることで、光源ユニット３００の側面３０３と、鍔部１４０のはみ出し部３１０と当たる第１面１４１と、枠部１５０の光源ユニット３００の側面３０３に対向する第２面１５１とで囲まれた空間８０１が形成されている。この空間８０１は、光源ユニット３００の側面３０３と枠部１５０の第２面１５１とのみによって形成される逆Ｖ字状の狭い溝ではなく、鍔部１４０の第１面１４１を底面とする深く広い溝になっている。そのため、光源ユニット３００の着脱時に、作業者が空間８０１に手を入れやすい。よって、光源ユニット３００を手で押さえながら行われる着脱作業が容易となる。 Since the lighting device 800 is configured as described above, the side surface 303 of the light source unit 300, the first surface 141 that contacts the protrusion 310 of the flange 140, and the side surface 303 of the light source unit 300 of the frame 150 are provided. A space 801 surrounded by the opposing second surface 151 is formed. This space 801 is not an inverted V-shaped narrow groove formed only by the side surface 303 of the light source unit 300 and the second surface 151 of the frame 150, but is deep and wide with the first surface 141 of the flange 140 as a bottom surface. It is a groove. Therefore, when attaching and detaching the light source unit 300, the operator can easily reach into the space 801. Therefore, the attachment / detachment operation performed while holding down the light source unit 300 by hand becomes easy.

本実施の形態において、枠部１５０は、本体枠１６０と、化粧枠１７０とを有する。 In the present embodiment, frame section 150 has main body frame 160 and decorative frame 170.

本体枠１６０は、鍔部１４０と一体に形成されている。本実施の形態において、器具本体１０１の形状は、平面視で四角形であり、本体枠１６０は、この四角形の各辺に対応する４つの板状部材１６１，１６２を有する。一方の４つの板状部材１６１は、鍔部１４０とつながり、器具本体１０１から光源ユニット３００へ向かう方向Ｄ１に延びている。他方の４つの板状部材１６２は、板状部材１６１とつながり、はみ出し部３１０がはみ出している方向Ｄ０に延びている。このように、本実施の形態において、本体枠１６０は、垂直に延びている４つの板状部材１６１と、水平に延びている４つの板状部材１６２とからなる。水平に延びている４つの板状部材１６２には、締結穴１５２が設けられている。 The main body frame 160 is formed integrally with the flange 140. In the present embodiment, the shape of device main body 101 is a quadrangle in plan view, and main body frame 160 has four plate-like members 161 and 162 corresponding to each side of the quadrangle. One of the four plate-like members 161 is connected to the flange 140 and extends in the direction D1 from the instrument body 101 to the light source unit 300. The other four plate members 162 are connected to the plate member 161 and extend in the direction D0 in which the protruding portion 310 protrudes. As described above, in the present embodiment, main body frame 160 includes four vertically extending plate members 161 and four horizontally extending plate members 162. Four plate-like members 162 extending horizontally are provided with fastening holes 152.

化粧枠１７０は、本体枠１６０に固定されている。具体的には、化粧枠１７０は、締結穴１５２に挿入されるネジ１５３によって、本体枠１６０の水平に延びている４つの板状部材１６２に締結されている。化粧枠１７０は、天井材９００に当たることでガタツキを抑制している。なお、化粧枠１７０は、ネジ１５３以外の固定具によって本体枠１６０に固定されてもよい。 The decorative frame 170 is fixed to the main frame 160. Specifically, the decorative frame 170 is fastened to four horizontally extending plate-like members 162 of the main body frame 160 by screws 153 inserted into the fastening holes 152. The decorative frame 170 suppresses rattling by hitting the ceiling material 900. Note that the decorative frame 170 may be fixed to the main frame 160 by a fixing tool other than the screw 153.

本実施の形態において、鍔部１４０と本体枠１６０は、器具本体１０１の本体面部１１０に取り付けられる枠体５００の一部である。枠体５００は、本体面部１１０にネジ等で固定されている水平面部５０１と、水平面部５０１とつながり、水平面部５０１に対して垂直に延びている垂直面部５０２とを有する。鍔部１４０は、垂直面部５０２とつながり、垂直面部５０２に対して垂直に延びている。本体枠１６０は、前述したように、その鍔部１４０につながっている。枠体５００は、器具本体１０１の四角形の各辺に対応するように４つ設けられ、１つ１つが個別に一体成形されている。なお、それぞれの枠体５００は、板金により形成されてもよいし、アルミニウム等を用いた押出成形により形成されてもよい。それぞれの枠体５００は、器具本体１０１と同じ材料により形成されてもよいし、異なる材料により形成されてもよい。 In the present embodiment, the flange 140 and the main body frame 160 are a part of the frame 500 attached to the main body surface 110 of the appliance main body 101. The frame body 500 has a horizontal surface portion 501 fixed to the main body surface portion 110 with screws or the like, and a vertical surface portion 502 connected to the horizontal surface portion 501 and extending perpendicular to the horizontal surface portion 501. The flange 140 is connected to the vertical surface 502 and extends perpendicular to the vertical surface 502. The main body frame 160 is connected to the flange 140 as described above. The four frame bodies 500 are provided so as to correspond to the respective sides of the square of the appliance main body 101, and each one is individually integrally formed. In addition, each frame 500 may be formed by sheet metal, or may be formed by extrusion using aluminum or the like. Each frame 500 may be formed of the same material as the device main body 101, or may be formed of a different material.

鍔部１４０は、垂直面部５０２の端から天井材９００に対して平行、即ち、水平方向に突き出している。鍔部１４０は、光源ユニット３００が器具本体１０１に取り付けられたときに光源ユニット３００の受け部となる。本体枠１６０の板状部材１６１は、鍔部１４０の端から天井材９００に対して垂直、即ち、鉛直方向に突き出している。本体枠１６０の板状部材１６２は、板状部材１６１の端から水平方向に突き出している。 The flange 140 protrudes from the end of the vertical surface 502 in parallel with the ceiling material 900, that is, in the horizontal direction. The flange 140 serves as a receiving portion for the light source unit 300 when the light source unit 300 is attached to the instrument main body 101. The plate-shaped member 161 of the main body frame 160 protrudes from the end of the flange 140 in a direction perpendicular to the ceiling material 900, that is, in a vertical direction. The plate member 162 of the main body frame 160 protrudes horizontally from the end of the plate member 161.

図５に示すように、垂直に延びている４つの板状部材１６１のうち、隣り合う板状部材１６１間には、隙間１６３が設けられている。水平に延びている４つの板状部材１６２のうち、隣り合う板状部材１６２間にも、隙間１６４が設けられている。 As shown in FIG. 5, a gap 163 is provided between adjacent plate members 161 among four vertically extending plate members 161. A gap 164 is also provided between adjacent plate members 162 among the four plate members 162 extending horizontally.

鍔部１４０の長手方向の端面は、鍔部１４０の短手方向の端面に対して約４５度で傾斜した面となっている。鍔部１４０は、本体枠１６０の板状部材１６１，１６２と同じように４つあり、４つの鍔部１４０のうち、隣接する鍔部１４０同士の長手方向の端面が突き合わせられている。つまり、本実施の形態では、鍔部１４０として、器具本体１０１の四角形の各辺に対応する複数の長手状の鍔部１４０が備えられ、隣り合う鍔部１４０同士の長手方向の端面が突き合わせられている。 The end surface of the flange 140 in the longitudinal direction is a surface inclined at about 45 degrees with respect to the end surface of the flange 140 in the short direction. Like the plate-like members 161 and 162 of the main body frame 160, there are four flanges 140, and the end faces in the longitudinal direction of the adjacent flanges 140 of the four flanges 140 are abutted. That is, in the present embodiment, as the flange 140, a plurality of elongated flanges 140 corresponding to the respective sides of the square of the appliance body 101 are provided, and the end faces in the longitudinal direction of the adjacent flanges 140 are abutted. ing.

本体枠１６０の一方の板状部材１６１は、鍔部１４０の短手方向の端面より垂直に形成されている。それぞれの板状部材１６１は、隣接する板状部材１６１との間に隙間１６３ができるように形成されている。 One plate-like member 161 of the main body frame 160 is formed to be perpendicular to the lateral end face of the flange 140. Each plate-shaped member 161 is formed such that a gap 163 is formed between adjacent plate-shaped members 161.

本体枠１６０の他方の板状部材１６２は、一方の板状部材１６１の短手方向の端面より垂直に形成されている。それぞれの板状部材１６２は、隣接する板状部材１６２のうち一方の短手方向の端面の一部が、他方の長手方向の端面と隙間１６４を介して対向するような長さ及び形状になっている。それぞれの板状部材１６２の長手方向の両端部には、前述した締結穴１５２が設けられている。 The other plate-shaped member 162 of the main body frame 160 is formed to be perpendicular to an end face of the one plate-shaped member 161 in the short direction. Each of the plate members 162 has a length and a shape such that a part of one end surface in the short direction of the adjacent plate members 162 faces the other end surface in the longitudinal direction via the gap 164. ing. The above-described fastening holes 152 are provided at both ends in the longitudinal direction of each plate member 162.

本実施の形態では、隙間１６３，１６４があることで、隣接する鍔部１４０の長手方向の端部同士を突き合わせるように枠体５００を配置した際に、各部分において加工等による寸法のバラツキが発生したとしても、隙間１６３，１６４で寸法差が吸収されるため、隣接する鍔部１４０の間に隙間が発生することを防止できる。よって、意匠性の低下が抑制される。なお、一方の隙間１６３がなく、他方の隙間１６４だけがある場合、或いは、他方の隙間１６４がなく、一方の隙間１６３だけがある場合であっても、一定の効果が得られる。 In the present embodiment, since the gaps 163 and 164 are provided, when the frame body 500 is arranged so that the ends in the longitudinal direction of the adjacent flange portions 140 abut each other, the dimensional variation due to processing or the like in each portion. Even if a gap occurs, the dimensional difference is absorbed by the gaps 163 and 164, so that a gap can be prevented from being generated between the adjacent flange portions 140. Therefore, a decrease in designability is suppressed. A certain effect can be obtained even when there is no gap 163 and there is only the gap 164 or when there is no gap 164 and there is only the gap 163.

本実施の形態において、化粧枠１７０は、断面が四角形の１辺が開口したような形状、即ち、「コ」の字のような形状をした部材を４つ組み合わせたものである。化粧枠１７０は、図４に示したように、本体枠１６０を覆うように、本体枠１６０に取り付けられる。このとき、化粧枠１７０により隙間１６３，１６４も覆われるため、枠体５００で意匠面となる面を有する要素は、鍔部１４０のみとなる。具体的には、鍔部１４０の第１面１４１の一部のみが露出することになる。このように、意匠面を小さい範囲に限定することで、意匠性を維持するための加工の手間及びコストを削減することができる。 In the present embodiment, the decorative frame 170 is a combination of four members each having a rectangular cross section with one side open, that is, a member having a U-shape. The decorative frame 170 is attached to the main frame 160 so as to cover the main frame 160 as shown in FIG. At this time, since the gaps 163 and 164 are also covered by the decorative frame 170, the only element having a surface to be a design surface in the frame 500 is the flange 140. Specifically, only a part of the first surface 141 of the flange 140 is exposed. In this way, by limiting the design surface to a small range, it is possible to reduce the labor and cost of processing for maintaining the design.

本実施の形態では、隙間１６３，１６４があることで、化粧枠１７０の内側の寸法と、本体枠１６０の板状部材１６１，１６２の寸法との間に加工等による差異が発生したとしても、隙間１６３，１６４で寸法差が吸収されるため、隣接する鍔部１４０の間に隙間が発生することを防止できる。よって、意匠性の低下が抑制される。 In the present embodiment, even if there is a difference due to processing or the like between the dimensions inside the decorative frame 170 and the dimensions of the plate members 161 and 162 of the main body frame 160 due to the presence of the gaps 163 and 164, Since the dimensional difference is absorbed by the gaps 163 and 164, it is possible to prevent a gap from being generated between the adjacent flange portions 140. Therefore, a decrease in designability is suppressed.

化粧枠１７０は、木製でもよいし、樹脂製でもよいし、アルミニウム等の金属製でもよい。隙間１６３，１６４があることで、木又は樹脂の周囲環境による膨張又は収縮も隙間１６３，１６４で吸収されるため、意匠性の低下が抑制される。 The decorative frame 170 may be made of wood, resin, or metal such as aluminum. With the gaps 163 and 164, the expansion or contraction of the wood or resin due to the surrounding environment is also absorbed by the gaps 163 and 164, so that a reduction in design is suppressed.

＊＊＊実施の形態の効果の説明＊＊＊
本実施の形態では、照明装置８００が、光源ユニット３００の着脱時に、作業者が光源ユニット３００と器具本体１０１に近い側の端部１４２で光源ユニット３００を受ける鍔部１４０と鍔部１４０の器具本体１０１から遠い側の端部１４３から延びる枠部１５０とで囲まれた広い空間８０１を使用して光源ユニット３００を手で押さえながら着脱作業を行うことができる構造になっている。そのため、光源ユニット３００の着脱作業が容易となる。 *** Explanation of effect of embodiment ***
In the present embodiment, when lighting device 800 attaches / detaches light source unit 300, a worker receives light source unit 300 at end 142 on the side closer to light source unit 300 and tool main body 101, and a fixture of flange 140. It has a structure in which a detachable operation can be performed while holding down the light source unit 300 by hand using a wide space 801 surrounded by the frame 150 extending from the end 143 farther from the main body 101. Therefore, the work of attaching and detaching the light source unit 300 becomes easy.

本実施の形態では、隣り合う鍔部１４０同士の長手方向の端面が突き合わせられている。この突き合わせられている部分は、上記空間８０１を形成する部分、即ち、外から見える部分であるため、この部分に隙間が生じると、意匠性が低下する。そのため、本実施の形態では、鍔部１４０につながっている本体枠１６０の板状部材１６１，１６２が、隣り合う板状部材１６１，１６２間に隙間１６３，１６４ができるような寸法、形状及び配置になっており、各部分において発生し得る寸法差を隙間１６３，１６４で吸収することができる。また、本体枠１６０に固定されている化粧枠１７０の内側部分と、本体枠１６０の板状部材１６１，１６２との間に発生し得る寸法差も隙間１６３，１６４で吸収することができる。よって、鍔部１４０同士の突き合わせられている部分に隙間が発生することを防止できる。その結果、意匠性が向上する。 In the present embodiment, the end faces in the longitudinal direction of adjacent flange portions 140 are abutted. The abutted portion is a portion that forms the space 801, that is, a portion that can be seen from the outside. Therefore, if a gap is formed in this portion, the design is reduced. Therefore, in the present embodiment, the plate-shaped members 161 and 162 of the main body frame 160 connected to the flange 140 are sized, shaped and arranged such that gaps 163 and 164 are formed between the adjacent plate-shaped members 161 and 162. The gaps 163 and 164 can absorb the dimensional difference that may occur in each part. In addition, the gaps 163 and 164 can also absorb a dimensional difference that can occur between the inner portion of the decorative frame 170 fixed to the main body frame 160 and the plate members 161 and 162 of the main body frame 160. Therefore, it is possible to prevent a gap from being generated in a portion where the flange portions 140 are abutted with each other. As a result, the design is improved.

また、本実施の形態では、器具本体１０１の形状が、平面視で四角形であるが、三角形或いは五角形等、四角形以外の多角形であってもよい。いずれの場合も、本体枠１６０は、当該多角形の各辺に対応する複数の板状部材１６１，１６２を有し、隣り合う板状部材１６１，１６２間に隙間１６３，１６４が設けられていることが望ましい。鍔部１４０としては、当該多角形の各辺に対応する複数の長手状の鍔部１４０が備えられ、隣り合う鍔部１４０同士の長手方向の端面が突き合わせられていることが望ましい。 Further, in the present embodiment, the shape of the appliance main body 101 is a quadrangle in plan view, but may be a polygon other than a quadrangle such as a triangle or a pentagon. In any case, the main body frame 160 has a plurality of plate members 161 and 162 corresponding to each side of the polygon, and gaps 163 and 164 are provided between the adjacent plate members 161 and 162. It is desirable. As the flange 140, it is preferable that a plurality of elongated flanges 140 corresponding to each side of the polygon are provided, and end faces in the longitudinal direction of the adjacent flanges 140 abut each other.

梁部１８３は、第１板状部材１８１と第２板状部材１８２とがつながる位置Ｐ１とは別の位置Ｐ２で第１板状部材１８１と第２板状部材１８２とにつながっている。梁部１８３は、第１板状部材１８１と第２板状部材１８２とを補強する部材である。梁部１８３があることで、第１板状部材１８１と第２板状部材１８２とのそれぞれの厚さを薄くしても強度を保つことができる。 The beam portion 183 is connected to the first plate member 181 and the second plate member 182 at a position P2 different from the position P1 where the first plate member 181 and the second plate member 182 are connected. The beam portion 183 is a member that reinforces the first plate member 181 and the second plate member 182. Since the beam portion 183 is provided, the strength can be maintained even when the thickness of each of the first plate member 181 and the second plate member 182 is reduced.

本実施の形態において、鍔部１４０と枠部１５０は、器具本体１０１の本体面部１１０に取り付けられる枠体５００の一部である。枠体５００は、本体面部１１０にネジ等で固定されている水平面部５０１と、水平面部５０１とつながり、水平面部５０１に対して垂直に延びている垂直面部５０２とを有する。鍔部１４０は、垂直面部５０２とつながり、垂直面部５０２に対して垂直に延びている。枠部１５０は、前述したように、その鍔部１４０につながっている。枠体５００は、器具本体１０１の四角形の各辺に対応するように４つ設けられ、１つ１つが個別に一体成形されている。 In the present embodiment, the flange 140 and the frame 150 are a part of the frame 500 attached to the main body surface 110 of the instrument main body 101. The frame body 500 has a horizontal surface portion 501 fixed to the main body surface portion 110 with screws or the like, and a vertical surface portion 502 connected to the horizontal surface portion 501 and extending perpendicular to the horizontal surface portion 501. The flange 140 is connected to the vertical surface 502 and extends perpendicular to the vertical surface 502. The frame 150 is connected to the flange 140 as described above. The four frame bodies 500 are provided so as to correspond to the respective sides of the square of the appliance main body 101, and each one is individually integrally formed.

鍔部１４０は、垂直面部５０２の端から天井材９００に対して平行、即ち、水平方向に突き出している。鍔部１４０は、光源ユニット３００が器具本体１０１に取り付けられたときに光源ユニット３００の受け部となる。枠部１５０の第１板状部材１８１は、鍔部１４０の端から天井材９００に対して斜めに突き出している。枠部１５０の第２板状部材１８２は、第１板状部材１８１の端から折り返すように、天井材９００に対して垂直に突き出し、天井材９００に当たっている。第２板状部材１８２は、天井材９００に当たることでガタツキを抑制している。枠部１５０の梁部１８３は、第１板状部材１８１と第２板状部材１８２とを天井材９００に対して水平につなげている。 The flange 140 protrudes from the end of the vertical surface 502 in parallel with the ceiling material 900, that is, in the horizontal direction. The flange 140 serves as a receiving portion for the light source unit 300 when the light source unit 300 is attached to the instrument main body 101. The first plate-like member 181 of the frame 150 protrudes obliquely from the end of the flange 140 with respect to the ceiling member 900. The second plate-shaped member 182 of the frame 150 protrudes perpendicularly to the ceiling member 900 so as to be folded from the end of the first plate-shaped member 181 and hits the ceiling member 900. The second plate-shaped member 182 suppresses rattling by hitting the ceiling member 900. The beam 183 of the frame 150 connects the first plate-like member 181 and the second plate-like member 182 horizontally to the ceiling material 900.

第１板状部材１８１は、鍔部１４０のはみ出し部３１０と当たる面である第１面１４１に対して斜めに延びている第２面１５１を有する。第２面１５１は、光源ユニット３００の側面３０３から出射される光を反射する面になっている。本実施の形態において、第１板状部材１８１は、光源ユニット３００とほぼ同じ高さに形成されている。第２面１５１は、第１板状部材１８１の高さ方向の一端から他端まで形成され、光源ユニット３００から側方に照射される光を下方へ反射する。なお、第２面１５１は、遮光するだけの面であってもよい。 The first plate-shaped member 181 has a second surface 151 that extends obliquely with respect to the first surface 141 that is the surface that comes into contact with the protrusion 310 of the flange 140. The second surface 151 is a surface that reflects light emitted from the side surface 303 of the light source unit 300. In the present embodiment, first plate-shaped member 181 is formed at substantially the same height as light source unit 300. The second surface 151 is formed from one end to the other end of the first plate-shaped member 181 in the height direction, and reflects downwardly light emitted from the light source unit 300 to the side. Note that the second surface 151 may be a surface that only blocks light.

ここで、隣接する枠体５００の連結方法に関して説明する。 Here, a method of connecting the adjacent frame bodies 500 will be described.

枠体５００の長手方向の端面は、枠体５００の短手方向の端面に対して約４５度で傾斜した面となっている。枠体５００は、前述したように４つあり、４つの枠体５００のうち、隣接する枠体５００同士の長手方向の端面が突き合わせられている。突き合わせられた枠体５００の端部同士は、枠部１５０の内側面、即ち、第１板状部材１８１と第２板状部材１８２とで対向する面に溶接が行われることで、接続される。溶接箇所が、外側に露出する面ではなく、枠部１５０の内側の面にあるため、意匠性の低下が抑制される。 The end face in the longitudinal direction of the frame 500 is a surface inclined at about 45 degrees with respect to the end face in the short direction of the frame 500. As described above, there are four frame bodies 500, and among the four frame bodies 500, the end faces in the longitudinal direction of adjacent frame bodies 500 abut each other. The ends of the butted frame 500 are connected to each other by welding to the inner surface of the frame 150, that is, the surface facing the first plate member 181 and the second plate member 182. . Since the welding location is not on the surface exposed to the outside, but on the inner surface of the frame 150, a decrease in design is suppressed.

隣接する枠体５００同士の長手方向の端面は、第１板状部材１８１と第２板状部材１８２とのそれぞれで突き合わせられている。よって、たとえ隙間が発生したとしても、２重に形成されている端部であるため、光が漏れにくい。 End surfaces of the adjacent frame bodies 500 in the longitudinal direction are abutted by the first plate member 181 and the second plate member 182, respectively. Therefore, even if a gap occurs, light is unlikely to leak because the end is formed in a double manner.

＊＊＊実施の形態の効果の説明＊＊＊
本実施の形態では、光源ユニット３００の側方に、第１板状部材１８１と第２板状部材１８２とを有する２重の枠部１５０が配置されている。よって、隣接する枠部１５０を連結するための溶接を、意匠面ではない枠部１５０の内側面に行うことができるため、意匠性の低下を抑制することができる。また、連結された枠部１５０の長手方向の端部における光の漏れを抑制することができる。 *** Explanation of effect of embodiment ***
In the present embodiment, a double frame 150 having a first plate-like member 181 and a second plate-like member 182 is arranged on the side of the light source unit 300. Therefore, the welding for connecting the adjacent frame portions 150 can be performed on the inner surface of the frame portion 150 which is not the design surface, so that the deterioration of the design property can be suppressed. In addition, it is possible to suppress light leakage at the end of the connected frame 150 in the longitudinal direction.

＊＊＊他の構成＊＊＊
本実施の形態では、鍔部１４０と枠部１５０が、器具本体１０１に固定される枠体５００の一部として構成されるが、鍔部１４０と枠部１５０は、器具本体１０１に一体に形成されてもよい。その場合、水平面部５０１と垂直面部５０２は不要となる。 *** Other configuration ***

May be done. In that case, the horizontal plane part 501 and the vertical plane part 502 become unnecessary.

また、本実施の形態では、器具本体１０１の形状が、平面視で四角形であるが、三角形或いは五角形等、四角形以外の多角形であってもよい。いずれの場合も、枠部１５０は、当該多角形の各辺に対応する複数の第１板状部材１８１と、同じく当該多角形の各辺に対応する複数の第２板状部材１８２とを有することが望ましい。鍔部１４０としては、当該多角形の各辺に対応する複数の長手状の鍔部１４０が備えられ、隣り合う鍔部１４０同士の長手方向の端面が突き合わせられていることが望ましい。 Further, in the present embodiment, the shape of the appliance main body 101 is a quadrangle in plan view, but may be a polygon other than a quadrangle such as a triangle or a pentagon. In any case, the frame 150 includes a plurality of first plate members 181 corresponding to each side of the polygon, and a plurality of second plate members 182 corresponding to each side of the polygon. It is desirable. As the flange 140, it is preferable that a plurality of elongated flanges 140 corresponding to each side of the polygon are provided, and end faces in the longitudinal direction of the adjacent flanges 140 abut each other.

鍔部１４０は、垂直面部５０２の端から天井材９００に対して平行、即ち、水平方向に突き出している。鍔部１４０は、光源ユニット３００が器具本体１０１に取り付けられたときに光源ユニット３００の受け部となる。枠部１５０の第１板状部材１８１は、鍔部１４０の端から天井材９００に対して垂直に突き出している。枠部１５０の第２板状部材１８２は、第１板状部材１８１の端から少なくとも片側に鍔状に突き出している。本実施の形態では、第２板状部材１８２は、第１板状部材１８１の端から両側に鍔状に突き出している。即ち、第２板状部材１８２は、第１板状部材１８１と「Ｔ」の字のような形状をなすように交差している。 The flange 140 protrudes from the end of the vertical surface 502 in parallel with the ceiling material 900, that is, in the horizontal direction. The flange 140 serves as a receiving portion for the light source unit 300 when the light source unit 300 is attached to the instrument main body 101. The first plate-shaped member 181 of the frame 150 protrudes perpendicularly to the ceiling member 900 from the end of the flange 140. The second plate-shaped member 182 of the frame 150 protrudes from an end of the first plate-shaped member 181 to at least one side in a flange shape. In the present embodiment, the second plate-shaped member 182 protrudes from both ends of the first plate-shaped member 181 in a flange shape. That is, the second plate-shaped member 182 intersects with the first plate-shaped member 181 so as to form a shape like a letter “T”.

図１０に示すように、第２板状部材１８２は、少なくとも一部が第１板状部材１８１の光源ユニット３００に対向する側から突き出して突き出し部１８４を形成している。即ち、第２板状部材１８２は、少なくとも一部が内側に突き出して突き出し部１８４を形成している。この内側の突き出し部１８４には、第１板状部材１８１の塗装色と第２板状部材１８２の塗装色との境目１８５が存在している。 As shown in FIG. 10, at least a portion of the second plate-shaped member 182 projects from the side of the first plate-shaped member 181 facing the light source unit 300 to form a protrusion 184. That is, the second plate-shaped member 182 at least partially protrudes inward to form the protruding portion 184. A boundary 185 between the paint color of the first plate-like member 181 and the paint color of the second plate-like member 182 exists in the inner protruding portion 184.

また、図１０に示すように、第２板状部材１８２は、少なくとも一部が第１板状部材１８１の光源ユニット３００に対向する側と反対側から突き出して突き出し部１８６を形成している。即ち、第２板状部材１８２は、少なくとも一部が外側に突き出して突き出し部１８４を形成している。この外側の突き出し部１８６にも、第１板状部材１８１の塗装色と第２板状部材１８２の塗装色との境目１８７が存在している。図９に示したように、突き出し部１８６は、天井材９００に当たることでガタツキを抑制している。 As shown in FIG. 10, at least a part of the second plate-shaped member 182 projects from a side of the first plate-shaped member 181 opposite to the side facing the light source unit 300 to form a protruding portion 186. That is, the second plate-shaped member 182 at least partially protrudes outward to form the protruding portion 184. The outer protrusion 186 also has a boundary 187 between the paint color of the first plate member 181 and the paint color of the second plate member 182. As illustrated in FIG. 9, the protrusion 186 suppresses rattling by hitting the ceiling member 900.

第１板状部材１８１は、鍔部１４０のはみ出し部３１０と当たる面である第１面１４１に対して垂直に延びている第２面１５１を有する。第２面１５１は、光源ユニット３００の側面３０３から出射される光を拡散させる凸凹面になっている。本実施の形態において、第１板状部材１８１は、光源ユニット３００とほぼ同じ高さに形成されている。第２面１５１は、第１板状部材１８１の高さ方向の一端から他端まで形成され、光源ユニット３００から側方に照射される光を拡散させる。なお、第２面１５１は、遮光するだけの面であってもよい。 The first plate-shaped member 181 has a second surface 151 extending perpendicularly to a first surface 141 that is a surface that comes into contact with the protrusion 310 of the flange 140. The second surface 151 is an uneven surface that diffuses light emitted from the side surface 303 of the light source unit 300. In the present embodiment, first plate-shaped member 181 is formed at substantially the same height as light source unit 300. The second surface 151 is formed from one end to the other end of the first plate-shaped member 181 in the height direction, and diffuses light emitted from the light source unit 300 to the side. Note that the second surface 151 may be a surface that only blocks light.

ここで、枠体５００の色の塗り分け方法に関して説明する。 Here, a method of applying different colors to the frame 500 will be described.

まず、第２板状部材１８２の本体部１００側の面である第２面１５１と、第２板状部材１８２の突き出し部１８４の器具本体１０１側を向く面である上面１９１との境界部分、及び、第２面１５１の反対側の面である外側面１９２と、第２板状部材１８２の突き出し部１８６の器具本体１０１側を向く面である上面１９３との境界部分が境目となるように、第１板状部材１８１と第２板状部材１８２とのどちらか一方がマスキングされる。そして、マスキングされてない方が塗装される。次に、第１板状部材１８１と第２板状部材１８２とのうち他方にも同様の作業が行われる。 First, a boundary portion between a second surface 151 that is a surface of the second plate-shaped member 182 on the main body 100 side and an upper surface 191 that is a surface of the protruding portion 184 of the second plate-shaped member 182 that faces the appliance body 101 side, Also, the boundary between the outer surface 192 opposite to the second surface 151 and the upper surface 193 of the protrusion 186 of the second plate-shaped member 182 facing the appliance body 101 becomes a boundary. One of the first plate member 181 and the second plate member 182 is masked. And those who are not masked are painted. Next, the same operation is performed on the other of the first plate member 181 and the second plate member 182.

＊＊＊実施の形態の効果の説明＊＊＊
本実施の形態において、マスキングの境目は、塗装色の境目１８５，１８７となる。一方の境目１８５は、第１板状部材１８１の第２面１５１と第２板状部材１８２の突き出し部１８４の上面１９１との境界部分にある。他方の境目１８７は、第１板状部材１８１の外側面１９２と第２板状部材１８２の突き出し部１８６の上面１９３との境界部分にある。これらの境界部分は、照明装置８００が被取り付け部に取り付けられた状態において見えない部分である。つまり、意匠面に色の境目１８５，１８７が現れない。よって、色の塗り分けによる意匠性の低下が抑制される。 *** Explanation of effect of embodiment ***
In the present embodiment, the boundaries of the masking are the boundaries 185 and 187 of the paint colors. One boundary 185 is located at the boundary between the second surface 151 of the first plate member 181 and the upper surface 191 of the protruding portion 184 of the second plate member 182. The other boundary 187 is at the boundary between the outer surface 192 of the first plate-shaped member 181 and the upper surface 193 of the protruding portion 186 of the second plate-shaped member 182. These boundary portions are portions that cannot be seen in a state where the lighting device 800 is attached to the attached portion. That is, color boundaries 185 and 187 do not appear on the design surface. Therefore, a decrease in design property due to different colors is suppressed.

色の境目１８５，１８７を、見えない部分に設けることで、マスキングの作業精度を高精度にしなくてもよくなる。よって、塗装作業が容易になる。なお、第１板状部材１８１と第２板状部材１８２とのどちらか一方のみが塗装されてもよい。 By providing the color boundaries 185 and 187 in invisible portions, it is not necessary to increase the masking work accuracy. Therefore, the painting operation becomes easy. Note that only one of the first plate member 181 and the second plate member 182 may be painted.
