以下、本発明の技術思想を高天井用の照明器具に適用した実施形態について、図面を参照して詳細に説明する。ただし、本発明の技術思想が適用可能な照明器具は高天井用に限定されるものではない。 Hereinafter, embodiments in which the technical idea of the present invention is applied to a lighting device for a high ceiling will be described in detail with reference to the drawings. However, the lighting fixture to which the technical idea of the present invention is applicable is not limited to the high ceiling.

本実施形態は、図２〜図５に示すように器具本体１、３つの灯具２、電源ブロック３、支持部材４などを備える。 As shown in FIGS. 2 to 5, this embodiment includes an instrument body 1, three lamps 2, a power supply block 3, a support member 4, and the like.

３つの灯具２は同一の構造を有するものであって、下面が開口した有底円筒形の灯具本体20、灯具本体20の開口面を塞ぐカバー21、灯具本体20に設けられる多数の放熱フィン22などを有している(図３及び図４参照)。 The three lamps 2 have the same structure, and are a bottomed cylindrical lamp body 20 having an open bottom surface, a cover 21 that closes the opening surface of the lamp body 20, and a number of radiating fins 22 provided on the lamp body 20. Etc. (see FIGS. 3 and 4).

灯具本体20の内底面に光源(図示せず)が配設されている。光源は、基板に実装される複数個の発光ダイオード(ＬＥＤ)チップと、透光性を有し且つ蛍光材料が混合された合成樹脂(例えば、シリコーン樹脂)製の封止部材とで構成される。すなわち、ＬＥＤチップから放射される光(例えば、青色光)の一部が蛍光材料で波長変換され、波長変換された光(例えば、黄色光)と波長変換されなかった光(青色光)が混ざることにより、光源から放射される光が全体として白色光となる。 A light source (not shown) is disposed on the inner bottom surface of the lamp body 20. The light source is composed of a plurality of light emitting diode (LED) chips mounted on a substrate, and a sealing member made of a synthetic resin (for example, a silicone resin) that has translucency and is mixed with a fluorescent material. . That is, a part of the light emitted from the LED chip (for example, blue light) is wavelength-converted with a fluorescent material, and the wavelength-converted light (for example, yellow light) and the light that has not been wavelength-converted (blue light) are mixed. As a result, the light emitted from the light source becomes white light as a whole.

カバー21は石英ガラスやアクリル樹脂などの透光性材料によって円板状に形成され、灯具本体20の下面に取り付けられる。 The cover 21 is formed in a disc shape from a translucent material such as quartz glass or acrylic resin, and is attached to the lower surface of the lamp body 20.

放熱フィン22は、薄い板状であって灯具本体20の下面を除く上面及び側面から所定の間隔を空けて立設されている。なお、灯具本体20と放熱フィン22とは、アルミダイカストによって一体に形成されている。 The heat radiating fins 22 are thin plate-like, and are erected at a predetermined interval from the upper surface and the side surface excluding the lower surface of the lamp body 20. The lamp body 20 and the heat radiating fins 22 are integrally formed by aluminum die casting.

電源ブロック３は、６つの電源ユニット(電源装置)30、１つの制御ユニット(制御装置)31、取付部材33などで構成される。 The power supply block 3 includes six power supply units (power supply devices) 30, one control unit (control device) 31, an attachment member 33, and the like.

６つの電源ユニット30は、２つの電源ユニット30がペアとなって１つの灯具２に直流電力を供給する。例えば、１つの灯具２の光源が２つのブロックに分割されており、１つの電源ユニット30からそれぞれ１つのブロックに直流電力が供給される。各電源ユニット30は、例えば、商用の交流電源から供給される交流電力を直流電力に変換するための電源回路が金属製且つ直方体形状のケース300に収納されてなる。ただし、ペアとなる２つの電源ユニット30は、同一のものであってもよいし、光源の各ブロックに応じて定格出力が異なるものであっても構わない。 The six power supply units 30 supply direct current power to one lamp 2 as a pair of the two power supply units 30. For example, the light source of one lamp 2 is divided into two blocks, and DC power is supplied to one block from one power supply unit 30. Each power supply unit 30 includes, for example, a power supply circuit for converting AC power supplied from a commercial AC power source into DC power, and is housed in a case 300 made of metal and a rectangular parallelepiped shape. However, the two power supply units 30 that form a pair may be the same, or may have different rated outputs depending on each block of the light source.

ケース300は、長手方向における一方の側面の端縁から長手方向に沿って突出する幅細の突片301が突設されている。そして、この突片301の上に、端子台32や制御ユニット31、各灯具２との電気配線に利用される３つの端子部302が配置されている。また、突片301の両端には、後述する取付ねじ34が挿通されるねじ挿通孔(図示せず)が貫通している。さらに、ケース300は、長手方向における他方の側面の端縁から長手方向に沿って突出する２つの突片304が突設されている。そして、各突片304にも取付ねじ34が挿通されるねじ挿通孔(図示せず)が１つずつ貫通している。 The case 300 is provided with a narrow projecting piece 301 projecting along the longitudinal direction from the edge of one side surface in the longitudinal direction. On the protruding piece 301, three terminal portions 302 used for electrical wiring with the terminal block 32, the control unit 31, and each lamp 2 are arranged. Further, a screw insertion hole (not shown) through which a mounting screw 34 described later is inserted passes through both ends of the projecting piece 301. Further, the case 300 is provided with two projecting pieces 304 projecting from the edge of the other side surface in the longitudinal direction along the longitudinal direction. A screw insertion hole (not shown) through which the mounting screw 34 is inserted passes through each projecting piece 304 one by one.

これら６つの電源ユニット30は、ペアとなる２つの電源ユニット30が１つの取付部材33にそれぞれ取り付けられる。取付部材33は、図６に示すように器具本体１に固定される長方形状の固定片330と、固定片330の上面より起立した平板状の取付板331と、取付板331の上端より固定片330と平行に折り曲げられた天板332とを有している。 Of these six power supply units 30, two power supply units 30 forming a pair are attached to one attachment member 33. As shown in FIG. 6, the mounting member 33 includes a rectangular fixed piece 330 fixed to the instrument body 1, a flat mounting plate 331 erected from the upper surface of the fixed piece 330, and a fixed piece from the upper end of the mounting plate 331. 330 and a top plate 332 bent in parallel.

取付板331には、１つの電源ユニット30について４つのねじ孔331A，331Bが貫設されており、一方の電源ユニット30の４つのねじ挿通孔に挿通される取付ねじ34がそれぞれねじ孔331Aにねじ止めされることで取付板331の表面に１つの電源ユニット30が取り付けられる。同様に、他方の電源ユニット30の４つのねじ挿通孔に挿通される取付ねじ34がそれぞれねじ孔331Bにねじ止めされることで取付板331の裏面に１つの電源ユニット30が取り付けられる。ただし、一方の電源ユニット30は、図６(ａ)に示すように長手方向に沿った側面が取付部材33の固定片330と平行になる姿勢で取付板331の表面に取り付けられる。これに対して他方の電源ユニット30は、図６(ｃ)に示すように長手方向に沿った側面が取付部材33の固定片330と略４５度傾いた姿勢で取付板331の裏面に取り付けられる。つまり、２つの電源ユニット30の取付板331に対する取付姿勢が異なっているため、各電源ユニット30を取り付けるためのねじ孔331A，331Bの位置をずらすことができる(図６(ａ)，(ｂ)参照)。その結果、１枚の取付板331に２つの電源ユニット30を取り付けることができる。 The mounting plate 331 has four screw holes 331A and 331B penetrating therethrough for one power supply unit 30, and mounting screws 34 inserted into the four screw insertion holes of one power supply unit 30 are respectively connected to the screw holes 331A. One power supply unit 30 is attached to the surface of the mounting plate 331 by being screwed. Similarly, one power supply unit 30 is attached to the back surface of the mounting plate 331 by fixing the mounting screws 34 inserted into the four screw insertion holes of the other power supply unit 30 to the screw holes 331B. However, one power supply unit 30 is attached to the surface of the mounting plate 331 in such a posture that the side surface along the longitudinal direction is parallel to the fixed piece 330 of the mounting member 33 as shown in FIG. On the other hand, the other power supply unit 30 is attached to the back surface of the mounting plate 331 in a posture in which the side surface along the longitudinal direction is inclined by approximately 45 degrees with the fixing piece 330 of the mounting member 33 as shown in FIG. . That is, since the mounting postures of the two power supply units 30 with respect to the mounting plate 331 are different, the positions of the screw holes 331A and 331B for mounting each power supply unit 30 can be shifted (FIGS. 6A and 6B). reference). As a result, two power supply units 30 can be attached to one mounting plate 331.

而して、２つの電源ユニット30が１つの取付板331の表面と裏面に取り付けられるので、１つの取付板331に１つの電源ユニット30のみを取り付ける場合と比較して、電源ユニット30が占めるスペースが減少し、その結果、照明器具全体として小型化を図ることができる。 Thus, since the two power supply units 30 are attached to the front and back surfaces of one mounting plate 331, the space occupied by the power supply unit 30 compared to the case where only one power supply unit 30 is attached to one mounting plate 331. As a result, the overall lighting apparatus can be reduced in size.

また、制御ユニット31は、各電源ユニット30を制御し、電源ユニット30から供給される直流電力を増減することで各灯具２を調光するものであり、直方体形状の金属製のケース310内に制御回路が収納されてなる。ケース310は、長手方向の両側面からそれぞれ突片311が突設され、各突片311にはねじ挿通孔が貫通している。 Further, the control unit 31 controls each power supply unit 30 and dimmes each lamp 2 by increasing / decreasing the DC power supplied from the power supply unit 30, and is placed in a rectangular parallelepiped metal case 310. A control circuit is accommodated. The case 310 has protruding pieces 311 protruding from both side surfaces in the longitudinal direction, and the protruding pieces 311 have screw insertion holes extending therethrough.

そして、制御ユニット31は、３つの取付部材33のうちの１つの取付部材33の天板332に取り付けられる(図６参照)。天板332の長手方向の両端にそれぞれねじ孔(図示せず)が設けられており、ケース310の各突片311のねじ挿通孔に挿通された取付ねじ35をねじ孔にねじ止めすることにより、天板332の下面側に制御ユニット31が取り付けられる(図６(ａ)，(ｂ)参照)。なお、制御ユニット31は天板332の上面側に取り付けることもできるが、天板332の下面側に取り付けることにより、塵埃がケース310内に進入し難くなるという利点がある。また、制御ユニット31を含む電源ブロック３においては、一方の電源ユニット30(傾いた姿勢で取り付けられている電源ユニット30)のケース300の側面に、商用の交流電源と接続するための端子台32が取り付けられる(図３(ａ)，(ｂ)参照)。 The control unit 31 is attached to the top plate 332 of one of the three attachment members 33 (see FIG. 6). Screw holes (not shown) are provided at both ends in the longitudinal direction of the top plate 332, and the mounting screws 35 inserted into the screw insertion holes of the projecting pieces 311 of the case 310 are screwed into the screw holes. The control unit 31 is attached to the lower surface side of the top plate 332 (see FIGS. 6A and 6B). Although the control unit 31 can be attached to the upper surface side of the top plate 332, the attachment of the control unit 31 to the lower surface side of the top plate 332 has an advantage that it is difficult for dust to enter the case 310. Further, in the power supply block 3 including the control unit 31, a terminal block 32 for connecting to a commercial AC power supply is provided on the side surface of the case 300 of one power supply unit 30 (the power supply unit 30 mounted in an inclined posture). Is attached (see FIGS. 3A and 3B).

器具本体１は、図２に示すように円形の底板10、器具本体１の側壁を構成する２つの側板11、底板10と２つの側板11を結合する２つの結合板12などで構成される。 As shown in FIG. 2, the instrument main body 1 includes a circular bottom plate 10, two side plates 11 that constitute the side walls of the instrument main body 1, two coupling plates 12 that couple the bottom plate 10 and the two side plates 11, and the like.

各結合板12は、底板10の下面における端部にねじ止めされる底板取付部120と、２つの側板11の長手方向の端部がそれぞれねじ止めされる側板取付部121と、支持部材４に取り付けるための支持台部122とが、金属板を曲げ加工することで一体に形成されてなる(図３(ｂ)参照)。すなわち、２つの結合板12によって底板10と２つの側板11が結合され、図４に示すように上面が開口した有底円筒形の器具本体１が構成される。 Each coupling plate 12 includes a bottom plate mounting portion 120 that is screwed to an end portion on the lower surface of the bottom plate 10, a side plate mounting portion 121 that is screwed to the longitudinal end portions of the two side plates 11, and the support member 4. A support base 122 for mounting is integrally formed by bending a metal plate (see FIG. 3B). That is, the bottom plate 10 and the two side plates 11 are coupled by the two coupling plates 12 to form a bottomed cylindrical instrument body 1 having an open upper surface as shown in FIG.

また支持台部122の先端部(上端部)に貫通した挿通孔(図示せず)にボルト123が挿通されている(図１参照)。このボルト123は、頭部123Aの外径が前記挿通孔の内径よりも大きく、且つ頭部123Aとねじ部123Bとの間に円筒部123C(雄ねじでない部分)を有しており、頭部123Aが外側(側壁側)となるように支持台部122の挿通孔に挿通される。そして、ボルト123のねじ部123Bに２つのナット124が締め付けられることにより、支持台部122にボルト123が固定される。なお、ボルト123の円筒部123Cの長さが支持台部122の板厚よりも十分に大きいため、支持台部122の側壁側の側面からボルト123の円筒部123Cが突出することになる。つまり、本実施形態では、支持台部122の側壁側の側面から突出するボルト123の円筒部123Cが係止突部に相当する。 Further, a bolt 123 is inserted through an insertion hole (not shown) penetrating the tip (upper end) of the support base 122 (see FIG. 1). The bolt 123 has an outer diameter of the head portion 123A larger than the inner diameter of the insertion hole, and has a cylindrical portion 123C (a portion that is not a male screw) between the head portion 123A and the screw portion 123B. Is inserted through the insertion hole of the support base 122 so that the outer side is on the outer side (side wall side). Then, the two nuts 124 are fastened to the screw portion 123B of the bolt 123, whereby the bolt 123 is fixed to the support base portion 122. Since the length of the cylindrical portion 123C of the bolt 123 is sufficiently larger than the plate thickness of the support base portion 122, the cylindrical portion 123C of the bolt 123 protrudes from the side surface of the support base portion 122. In other words, in the present embodiment, the cylindrical portion 123C of the bolt 123 protruding from the side surface of the support base 122 corresponds to the locking protrusion.

底板10には３つの円形の窓孔(図示せず)が貫通しており、各窓孔に灯具２の下端部が挿通される。これら３つの窓孔は、底板10の中心と窓孔の中心とを結ぶ直線の角度がそれぞれ120°となる位置に設けられている(図２(ｂ)参照)。なお、灯具本体20の側面には外向きに突出するフランジ部23が設けられており、このフランジ部23が底板10の上面側にねじ止めされることによって、灯具２が底板10に取り付けられる(図３参照)。 Three circular window holes (not shown) pass through the bottom plate 10, and the lower end portion of the lamp 2 is inserted into each window hole. These three window holes are provided at positions where the angles of the straight lines connecting the center of the bottom plate 10 and the center of the window hole are 120 ° (see FIG. 2B). In addition, the flange part 23 which protrudes outward is provided in the side surface of the lamp main body 20, The lamp | ramp 2 is attached to the baseplate 10 by screwing this flange part 23 to the upper surface side of the baseplate 10 ( (See FIG. 3).

また、底板10の中心と、隣り合う窓孔の間とに、それぞれ円形の通気孔101が貫通している。つまり、灯具２の放熱フィン22からの放熱で暖められた空気が上昇することにより、器具本体１の外の冷えた空気が通気孔101を通して器具本体１の内部に導入されるので、放熱フィン22による放熱効果を高めることができる。 Further, circular vent holes 101 pass through the center of the bottom plate 10 and between adjacent window holes. That is, since the air heated by the heat radiation from the radiation fins 22 of the lamp 2 rises, the cold air outside the instrument body 1 is introduced into the interior of the instrument body 1 through the vent hole 101. The heat dissipation effect by can be enhanced.

ここで、器具本体１内においては、隣り合う２つの灯具２と側壁(側板11)との間にそれぞれ空間(領域)が形成される。そして、各電源ブロック３は、取付部材33の固定片330が前記領域における底板10にねじ止めされることにより、取付板331と器具本体１の側壁(側板11)とが対向するように、３つの領域にそれぞれ１つずつ配置される(図３(ａ)及び図４，５参照)。このように本実施形態では、デッドスペースとなる領域に電源ブロック３を配置することにより、器具本体１の小型化を図ることができる。 Here, in the instrument main body 1, spaces (regions) are formed between the two adjacent lamps 2 and the side wall (side plate 11). Each power supply block 3 is connected to the bottom plate 10 in the region by screwing the fixing piece 330 of the mounting member 33 so that the mounting plate 331 and the side wall (side plate 11) of the instrument body 1 face each other. One is arranged in each of the regions (see FIG. 3A and FIGS. 4 and 5). Thus, in this embodiment, the instrument main body 1 can be reduced in size by arranging the power supply block 3 in a region that becomes a dead space.

支持部材４は、図７に示すように長方形状の固定部40と、固定部40の長手方向における両端からそれぞれ下向きに突出する２つの腕部41とが金属板を曲げ加工することで一体に形成されてなる。 As shown in FIG. 7, the support member 4 is integrally formed by bending a metal plate with a rectangular fixed portion 40 and two arm portions 41 protruding downward from both ends in the longitudinal direction of the fixed portion 40. Formed.

固定部40は、長手方向に沿って３つのねじ挿通孔400が貫通しており、これら３つのねじ挿通孔400に挿通される取付ボルト(図示せず)によって、造営材(天井)に固定される。ただし、長手方向に沿った両端部を下向きに折り曲げることにより、固定部40の強度の向上を図っている。 The fixing portion 40 has three screw insertion holes 400 extending therethrough along the longitudinal direction, and is fixed to the construction material (ceiling) by mounting bolts (not shown) inserted through the three screw insertion holes 400. The However, the strength of the fixed portion 40 is improved by bending both end portions along the longitudinal direction downward.

腕部41は、上端が固定部40に連結された連結部410と、連結部410から固定部40側に略直角に曲げ起こされた平坦部411と、平坦部411の先端から下向き且つ略直角に折曲された取付部412とを有する。また、平坦部411には、支持台部122に取り付けられているボルト123の頭部123Aが挿通可能な寸法を有する略矩形の第１挿通溝413が貫通している。さらに、取付部412には、頭部123Aが挿通不能且つボルト123の円筒部123Cが挿通可能な寸法を有して第１挿通溝413と繋がった第２挿通溝414が貫通している。第２挿通溝414は、下端が半円弧形の長孔形状に形成され、上端において第１挿通溝413と繋がっており、左右方向の幅寸法がボルト123の頭部123Aよりも狭く且つ円筒部123Cよりも広い寸法とされている。なお、第１挿通溝413と第２挿通溝414とで被係止部が構成されている。 The arm part 41 includes a connecting part 410 whose upper end is connected to the fixed part 40, a flat part 411 bent up at a substantially right angle from the connecting part 410 to the fixed part 40, and a downward and substantially right angle from the tip of the flat part 411. And a mounting portion 412 that is bent at the same time. Further, a substantially rectangular first insertion groove 413 having a dimension capable of inserting the head 123A of the bolt 123 attached to the support base portion 122 passes through the flat portion 411. Further, the attachment portion 412 has a second insertion groove 414 passing through the first insertion groove 413 having a dimension that the head portion 123A cannot be inserted and the cylindrical portion 123C of the bolt 123 can be inserted. The second insertion groove 414 is formed in a long hole shape having a semicircular arc shape at the lower end, and is connected to the first insertion groove 413 at the upper end. The width dimension in the left-right direction is narrower than the head 123A of the bolt 123 and is cylindrical. The dimensions are wider than the part 123C. The first insertion groove 413 and the second insertion groove 414 constitute a locked portion.

次に、本実施形態の照明器具を造営材(天井)に取り付ける際の手順(施工手順)を説明する。 Next, a procedure (construction procedure) for attaching the lighting fixture of the present embodiment to a construction material (ceiling) will be described.

初めに、支持部材４の固定部40を造営材(天井)に固定する。なお、支持部材４は、水平な天井だけでなく、いわゆる傾斜天井にも固定することができる。 First, the fixing portion 40 of the support member 4 is fixed to the construction material (ceiling). The support member 4 can be fixed not only on a horizontal ceiling but also on a so-called inclined ceiling.

続いて、各結合板12から突出しているボルト123の頭部123Aが支持部材４の第１挿通溝413の真上に来るように器具本体１を移動させる。そして、器具本体１を下降させると２本のボルト123の頭部123Aがそれぞれ第１挿通溝413に挿通され、さらに、各ボルト123の円筒部123Cが第１挿通溝413を通って第２挿通溝414に挿通される。 Subsequently, the instrument main body 1 is moved so that the head 123A of the bolt 123 protruding from each coupling plate 12 is located directly above the first insertion groove 413 of the support member 4. When the instrument body 1 is lowered, the heads 123A of the two bolts 123 are respectively inserted into the first insertion grooves 413, and the cylindrical portions 123C of the respective bolts 123 are passed through the first insertion grooves 413 to be second inserted. It is inserted into the groove 414.

つまり、器具本体１に固定されている２本のボルト123が、支持部材４の一対の取付部412に設けられている２つの第２挿通溝414の周縁に各別に係止されることにより、器具本体１が支持部材４に吊り下げて支持される。このように第１挿通溝413から第２挿通溝414へボルト123を挿通するだけで器具本体１を支持部材４に支持させることができるので、照明器具を天井に設置する施工作業の簡素化を図ることができる。 That is, the two bolts 123 fixed to the instrument body 1 are respectively locked to the peripheral edges of the two second insertion grooves 414 provided in the pair of attachment portions 412 of the support member 4, The instrument body 1 is supported by being suspended from the support member 4. Thus, since the fixture body 1 can be supported by the support member 4 simply by inserting the bolt 123 from the first insertion groove 413 to the second insertion groove 414, the construction work for installing the lighting fixture on the ceiling can be simplified. Can be planned.

ここで、図１に示すように、ボルト123の円筒部123Cの長さ寸法が支持台部122の板厚と取付部412の板厚の合計寸法よりも長いため、円筒部123Cを支点として、器具本体１が支持部材４に対して回動自在となっている。そのため、図９に示すように支持部材４が傾斜天井に固定される場合、特に調整作業を行わなくとも、器具本体１を自重で回動させて水平な状態に安定させることができる。 Here, as shown in FIG. 1, since the length dimension of the cylindrical portion 123C of the bolt 123 is longer than the total dimension of the plate thickness of the support base portion 122 and the mounting portion 412, the cylindrical portion 123C is used as a fulcrum. The instrument main body 1 is rotatable with respect to the support member 4. Therefore, as shown in FIG. 9, when the support member 4 is fixed to the inclined ceiling, the instrument body 1 can be rotated by its own weight to be stabilized in a horizontal state without any adjustment work.

ところで、灯具２及び電源ブロック３を含む器具本体１は、10数kg〜20数kgの重量があるので、通常、ボルト123が挿通溝413，414を抜けて支持部材４から脱落することはない。しかしながら、地震の揺れによって器具本体１が上向きに移動した場合、ボルト123が挿通溝413，414を抜けて器具本体１が支持部材４から脱落する可能性がある。 By the way, since the fixture main body 1 including the lamp 2 and the power supply block 3 has a weight of several tens to several tens of kilograms, the bolt 123 usually does not fall out of the support member 4 through the insertion grooves 413 and 414. . However, when the instrument main body 1 moves upward due to the shaking of the earthquake, the bolt 123 may pass through the insertion grooves 413 and 414 and the instrument main body 1 may fall off the support member 4.

そこで、第１挿通溝413を塞ぐ位置と、第１挿通溝413を開放する位置との間を変位する抜け止め部材５を支持部材４に設けている。この抜け止め部材５は、図８に示すように主部50と、第１固定部51と、第２固定部52と、規制部53と、対向部54とが金属板を打ち抜き加工及び曲げ加工することで一体に形成されてなる。 Therefore, the supporting member 4 is provided with a retaining member 5 that displaces between a position where the first insertion groove 413 is closed and a position where the first insertion groove 413 is opened. As shown in FIG. 8, the retaining member 5 includes a main portion 50, a first fixing portion 51, a second fixing portion 52, a restricting portion 53, and a facing portion 54 that punch and process a metal plate. By doing so, it is formed integrally.

主部50は、帯状に形成されており、第１挿通溝413の大部分を覆うことができる寸法(面積)を有している。第１固定部51と第２固定部52は、いずれも主部50よりも大きい幅寸法を有している。また第１固定部51は、厚み方向に貫通するねじ挿通孔51Aが形成されている。一方、第２固定部52は、厚み方向に貫通し且つ幅方向の一端側が開放された長孔状のねじ挿通溝52Aが形成されている。さらに、第２固定部52は、ねじ挿通溝52Aの開放端側の端部が下向きに折り曲げられて突部52Bが形成されている。規制部53は、略凸形に形成され、主部50の長手方向中央から主部50と水平に突出している。また、対向部54は、略正方形に形成され、主部50の長手方向に沿った端縁から下向きに曲げ起こされている。 The main portion 50 is formed in a belt shape and has a dimension (area) that can cover most of the first insertion groove 413. Each of the first fixing portion 51 and the second fixing portion 52 has a larger width dimension than the main portion 50. Further, the first fixing portion 51 is formed with a screw insertion hole 51A penetrating in the thickness direction. On the other hand, the second fixing portion 52 is formed with a long hole-like screw insertion groove 52A that penetrates in the thickness direction and is open at one end in the width direction. Further, in the second fixing portion 52, the end portion on the open end side of the screw insertion groove 52A is bent downward to form a protruding portion 52B. The restricting portion 53 is formed in a substantially convex shape and protrudes horizontally from the main portion 50 from the longitudinal center of the main portion 50. The facing portion 54 is formed in a substantially square shape, and is bent downward from the edge along the longitudinal direction of the main portion 50.

抜け止め部材５は、支持部材４の各腕部41における平坦部411に２本のねじ６でねじ止めされる。つまり、第１固定部51のねじ挿通孔51Aに下から挿通されるねじ６が、平坦部411に設けられるねじ孔(図示せず)に締め込まれることで第１固定部51が平坦部411に固定される。一方、平坦部411に設けられる別のねじ孔(図示せず)に緩く締め込まれたねじ６をねじ挿通溝52Aに挿通した後、このねじ６をきつく締め込むことで第２固定部52が平坦部411に固定される。ただし、ねじ６を緩めた状態では、第１固定部51を固定するねじ６を支点として、抜け止め部材５が平坦部411に対して回動可能となっている。 The retaining member 5 is screwed to the flat portion 411 of each arm portion 41 of the support member 4 with two screws 6. That is, the screw 6 inserted from below into the screw insertion hole 51A of the first fixing portion 51 is tightened into a screw hole (not shown) provided in the flat portion 411, whereby the first fixing portion 51 is flat. Fixed to. On the other hand, after the screw 6 loosely tightened in another screw hole (not shown) provided in the flat portion 411 is inserted into the screw insertion groove 52A, the second fixing portion 52 is tightened by tightening the screw 6 tightly. It is fixed to the flat part 411. However, when the screw 6 is loosened, the retaining member 5 is rotatable with respect to the flat portion 411 with the screw 6 that fixes the first fixing portion 51 as a fulcrum.

つまり、抜け止め部材５を回動させて主部50が第１挿通溝413を開放する位置に変位させた状態で第１挿通溝413から第２挿通溝414へボルト123の頭部123A及び円筒部123Cを挿通し、その後、抜け止め部材５を回動させて第２固定部52を平坦部411に固定すればよい。第２固定部52を平坦部411に固定した状態では、主部50が第１挿通溝413の大部分を覆う(塞ぐ)ので、地震で器具本体１が上向きに移動しても、ボルト123が挿通溝413，414を抜けて器具本体１が支持部材４から脱落する虞がない。また、第２固定部52を平坦部411に固定した状態において、対向部54がボルト123の頭部123Aと対向し、且つその対向距離がボルト123の全長よりも十分短くなっている(図１参照)。したがって、地震などによる振動によってナット124が緩んでねじ部123Bから脱落したとしても、ボルト123の頭部123Aが対向部54に当たるため、支持台部122及び取付部412からボルト123が脱落する虞がないものである。 That is, the head 123A of the bolt 123 and the cylinder are moved from the first insertion groove 413 to the second insertion groove 414 in a state where the retaining member 5 is rotated and the main portion 50 is displaced to a position where the first insertion groove 413 is opened. The second fixing portion 52 may be fixed to the flat portion 411 by inserting the portion 123C and then rotating the retaining member 5 to rotate. In the state where the second fixing portion 52 is fixed to the flat portion 411, the main portion 50 covers (closes) most of the first insertion groove 413. Therefore, even if the instrument body 1 moves upward due to an earthquake, the bolt 123 is There is no possibility that the instrument body 1 will fall off the support member 4 through the insertion grooves 413 and 414. Further, in a state where the second fixing portion 52 is fixed to the flat portion 411, the facing portion 54 faces the head portion 123A of the bolt 123, and the facing distance is sufficiently shorter than the total length of the bolt 123 (FIG. 1). reference). Therefore, even if the nut 124 is loosened due to vibration due to an earthquake or the like and falls off the threaded portion 123B, the head 123A of the bolt 123 hits the facing portion 54, and therefore the bolt 123 may fall off from the support base portion 122 and the mounting portion 412. There is nothing.

さらに、主部50が第１挿通溝413を塞いでいる状態においては、主部50から突出する規制部53が、第１挿通溝413を通って支持台部122の先端と対向する。したがって、支持部材４に対して器具本体１が回動する際、図４(ａ)に示すように規制部53が支持台部122の先端に干渉することで器具本体１の回動範囲が規制されることになる。つまり、地震の揺れなどで器具本体１が回動して天井(特に傾斜天井)に衝突することが回避できる。 Further, in a state where the main portion 50 closes the first insertion groove 413, the restricting portion 53 protruding from the main portion 50 faces the tip of the support base portion 122 through the first insertion groove 413. Therefore, when the instrument main body 1 rotates with respect to the support member 4, the restricting portion 53 interferes with the tip of the support base 122 as shown in FIG. Will be. That is, it is possible to avoid the instrument body 1 from rotating and colliding with the ceiling (particularly an inclined ceiling) due to an earthquake shake or the like.

ところで、上述のように、円筒部123Cの軸方向から見た第２挿通溝414の形状が半円弧状である場合、図１１に示すように円筒部123Cが第２挿通溝414と１箇所(鉛直方向の下端部)のみで接することになる。そうすると、地震等の影響で器具本体１に揺れが発生した場合、円筒部123Cと第２挿通溝414の内周面との摩擦力が相対的に小さいために器具本体１の揺れが長時間に渡って継続する可能性がある。 By the way, as described above, when the shape of the second insertion groove 414 viewed from the axial direction of the cylindrical portion 123C is a semicircular arc shape, the cylindrical portion 123C and the second insertion groove 414 are disposed at one location (see FIG. 11). It touches only at the lower end in the vertical direction. Then, when the instrument body 1 sways due to an earthquake or the like, the instrument body 1 sways for a long time because the frictional force between the cylindrical portion 123C and the inner peripheral surface of the second insertion groove 414 is relatively small. May continue across.

そこで、図１０に示すように、円筒部123Cの軸方向から見た第２挿通溝の形状を、円筒部123Cと複数の辺(図示例では左右２つの斜辺)で接する多角形状(図示例では台形状)とすることが好ましい。すなわち、第２挿通溝414が半円弧状である場合と比較して、円筒部123Cと第２挿通溝414の内周面との摩擦力が増大するので、器具本体１に生じた揺れが減衰する時間を早めることができる。ただし、図１０に示すように第２挿通溝414の底辺(最も下になる辺)と円筒部123Cとの間に隙間Ｇを設けることが好ましい。例えば、２つの斜辺と底辺の３箇所で円筒部123Cに接する場合、２つの斜辺と比べて、器具本体１の重量との関係で底辺における摩擦力の影響が相対的に高くなるので、円筒部123Cにおける底辺に接する部分が削れやすくなることがある。そのため、第２挿通溝414の底辺と円筒部123Cとの間に隙間Ｇを設け、円筒部123Cが第２挿通溝414の２つの斜辺とのみ接するようにすれば、各斜辺との接触部分の削れを抑えることができる。なお、第２挿通溝414の形状は台形に限定されず、台形以外の多角形(例えば、五角形や六角形)であっても構わない。 Therefore, as shown in FIG. 10, the shape of the second insertion groove seen from the axial direction of the cylindrical portion 123C is a polygonal shape (in the illustrated example, two diagonal sides) in contact with the cylindrical portion 123C. A trapezoidal shape is preferable. That is, compared with the case where the second insertion groove 414 has a semicircular arc shape, the frictional force between the cylindrical portion 123C and the inner peripheral surface of the second insertion groove 414 increases, so that the vibration generated in the instrument body 1 is attenuated. I can speed up the time to do. However, as shown in FIG. 10, it is preferable to provide a gap G between the bottom side (the lowest side) of the second insertion groove 414 and the cylindrical portion 123C. For example, when the cylindrical portion 123C is in contact with three oblique sides and the bottom side, the influence of the frictional force on the bottom side is relatively higher in relation to the weight of the instrument body 1 than the two oblique sides. The part in contact with the bottom of 123C may be easily cut. Therefore, if a gap G is provided between the bottom side of the second insertion groove 414 and the cylindrical portion 123C so that the cylindrical portion 123C is in contact with only two oblique sides of the second insertion groove 414, contact portions with the respective oblique sides Shave can be suppressed. The shape of the second insertion groove 414 is not limited to a trapezoid, and may be a polygon other than a trapezoid (for example, a pentagon or a hexagon).
