Further, the urging means is an elastic body such as a coiled torsion spring, for example, and the latch fitting 55 is moved in a predetermined direction, that is, in a direction in which the latch portion 54 and the operation portion 58 protrude outward (in the direction of arrow A shown in FIG. 1). Energized. Further, a latch fitting arrangement portion 12g in which the latch fitting 55 is arranged is cut out in the side edge plate portion 12b of the instrument main body 12. That is, as shown in FIG. 1, the latch fitting 55 is urged outward by the urging means, that is, in the direction of the arrow A, and is disposed at a position indicated by a solid line when no force is applied from the outside. Further, when the operating portion 58 is pushed from the outside to the inside, that is, in the direction of the arrow B, the latch fitting 55 rotates in the direction of the arrow B with the shaft pin 57 as the rotation axis against the urging force of the urging means, Move to the position indicated by the imaginary line C.

そして、制光体18は、ヒンジ機構36に軸支され、一側のピン42を回転軸として、実線に示す位置から、想像線Ｄ，Ｅなどに示す位置へと回動する。そして、制光体18の他側部を器具本体12側に持ち上げると、ラッチ部54に当板47が当接して、付勢手段の付勢力に抗してラッチ部54すなわちラッチ金具55を内側(矢印Ｂ方向)に回動させる。そして、当板47がラッチ部54の頂部を通過すると、付勢手段の付勢力によりラッチ部54すなわちラッチ金具55は外側(矢印Ａ方向)に回動し、ラッチ部54がラッチ受部46の係合受部48に当接する。この状態で、制光体18が所定の位置に保持される。また、制光体18を所定の位置に保持した状態で、操作部58を内側に押動することにより、ラッチ部54がラッチ受部46が離れ、すなわち係合が解除されて、制光体18を開くことができる。 The light control body 18 is pivotally supported by the hinge mechanism 36 and rotates from the position indicated by the solid line to the position indicated by the imaginary lines D, E, etc., with the pin 42 on one side as the rotation axis. Then, when the other side portion of the light control body 18 is lifted to the instrument body 12 side, the abutment plate 47 comes into contact with the latch portion 54, and the latch portion 54, that is, the latch fitting 55 is moved inside against the biasing force of the biasing means. Turn in the direction of arrow B. When the abutment plate 47 passes through the top of the latch portion 54, the latch portion 54, that is, the latch fitting 55 is rotated outward (in the direction of arrow A) by the biasing force of the biasing means, and the latch portion 54 is moved to the latch receiving portion 46. It abuts on the engagement receiving portion 48. In this state, the light control body 18 is held at a predetermined position. Further, when the light control body 18 is held at a predetermined position, the operation portion 58 is pushed inward, whereby the latch portion 54 is separated from the latch receiving portion 46, that is, the engagement is released, and the light control body 18 can be opened.

このように、本実施の形態によれば、器具本体12とバッフル組立である制光体18を備えたいわばバッフル付きの照明器具10において、制光体18の一側をヒンジ機構36で回動可能に支持し、他側をラッチ機構38で係脱可能に支持したため、開いた状態の制光体18を一側を軸として他側を持ち上げて回動させるのみで制光体18を所定の位置に確実に係合保持できるとともに、他側に配置されたラッチ金具55の操作部58を押動するのみで係合を解除してヒンジ機構36を開くことができ、ねじを用いる構成や照明器具10の両端面に操作部が配置された構成に比べ、作業者が１人でも容易に制光体18を開閉でき、ランプＬの交換などの保守作業の作業性を向上できる。すなわち、照明器具10の両端部にラッチ機構を設けると、１人の作業者では手が両端のラッチ機構に届かず、複数の作業者が必要になる場合がある。また、照明器具10の両端部にラッチ機構を設けると、ラッチ機構の係合部及び係合受部などの寸法が十分に確保できない場合がある。 As described above, according to the present embodiment, in the lighting fixture 10 with a baffle, which includes the fixture body 12 and the baffle assembled light control body 18, one side of the light control body 18 is rotated by the hinge mechanism 36. Since the other side is detachably supported by the latch mechanism 38, the dimmer 18 in the open state is lifted up with the other side as an axis and rotated to rotate the dimmer 18 in a predetermined state. It can be securely held in position, and the hinge mechanism 36 can be opened by simply pushing the operating part 58 of the latch fitting 55 arranged on the other side. Compared to the configuration in which the operation units are arranged on both end faces of the instrument 10, even one operator can easily open and close the light control body 18, and the workability of maintenance work such as replacement of the lamp L can be improved. That is, if a latch mechanism is provided at both ends of the luminaire 10, a single worker may not reach the latch mechanism at both ends, and a plurality of workers may be required. In addition, when a latch mechanism is provided at both ends of the luminaire 10, there may be a case where the dimensions of the engaging portion and the engaging receiving portion of the latch mechanism cannot be secured sufficiently.

また、ラッチ機構38の付勢手段は、ラッチ金具55を制光体18の移動方向に交差する方向に付勢するため、バネ材を用いて制光体を吊り下げ支持する構成に比べ、付勢手段の経年劣化による影響は小さく、制光体18の垂れ下がりなどを抑制し、外観を向上できる。 Further, the biasing means of the latch mechanism 38 biases the latch fitting 55 in a direction crossing the moving direction of the light control body 18, so that the biasing means is biased compared to the configuration in which the light control body is suspended and supported using a spring material. The influence of the aging means due to aging is small, the drooping of the light control body 18 is suppressed, and the appearance can be improved.

そして、ラッチ機構38の操作部58などが照明器具10の端部ではなく側部に配置されているため、照明器具10の端部での作業が不要になり、また、照明器具10の端部の構造が簡略になり、複数の照明器具10を容易に連結配置できる。 Since the operation unit 58 of the latch mechanism 38 is arranged on the side instead of the end of the luminaire 10, work at the end of the luminaire 10 becomes unnecessary, and the end of the luminaire 10 Thus, the plurality of lighting fixtures 10 can be easily connected and arranged.

また、制光体18は、バッフル41同士を連結する全てのピン42を端部まで設けて端板部43に固着しており、ピン42を制光体18の全長すなわち照明器具10の略全長に設けたため、制光体18及びこの制光体18が取り付けられた器具本体11、ひいては照明器具10全体の強度を向上でき、制光体18や器具本体11の自重などによる変形を抑制し、外観を向上できるとともに、異音の発生を抑制できる。 In addition, the light control body 18 is provided with all pins 42 connecting the baffles 41 to the end and fixed to the end plate portion 43, and the pins 42 are connected to the entire length of the light control body 18, that is, the substantially total length of the lighting fixture 10. Therefore, it is possible to improve the strength of the light control body 18 and the fixture body 11 to which the light control body 18 is attached, and thus the overall lighting fixture 10, and suppress deformation due to the weight of the light control body 18 and the fixture body 11, etc. The appearance can be improved and the occurrence of abnormal noise can be suppressed.

さらに、制光体18は、長手方向の端部近傍に側板部44を備えたカバー45を設け、ランプソケット15を覆っているとともに、この側板部44を備えたカバー45により、ラッチ機構38も操作部58を除いて収納されほぼ外部から直視できなくなり、外観を向上できる。さらに、操作部58は、器具本体12と同様の色とし、制光体18を保持した状態で、操作部58が器具本体12の側縁板部12bとほぼ同一面に位置するように設定することにより、外観を向上できる。 Further, the light control body 18 is provided with a cover 45 provided with a side plate portion 44 in the vicinity of the end portion in the longitudinal direction, covers the lamp socket 15, and the cover 45 provided with the side plate portion 44 also provides a latch mechanism 38. It is housed except for the operation unit 58 and cannot be seen directly from the outside, and the appearance can be improved. Further, the operation unit 58 is set to have the same color as that of the instrument body 12 so that the operation part 58 is positioned substantially flush with the side edge plate part 12b of the instrument body 12 while holding the light control body 18. Thus, the appearance can be improved.

そして、この側板部44は、バッフル41及び端板部43に固着され、制光体18の強度を向上できる。 The side plate portion 44 is fixed to the baffle 41 and the end plate portion 43, so that the strength of the light control body 18 can be improved.

また、制光体18は、断面形状が略半円形状であり、バッフル41、これらバッフル41同士を連結するピン42、これらピン42同士を連結する端板部43及び側板部44で構成されているため、ガードとしての印象が小さく、意匠性を向上できる。 The light control body 18 has a substantially semicircular cross-sectional shape, and includes a baffle 41, pins 42 that connect the baffles 41, end plate portions 43 and side plate portions 44 that connect the pins 42 to each other. Therefore, the impression as a guard is small and the design can be improved.

また、ヒンジ機構36は、バッフル41を連結するピン42の１本を回転軸として兼用するため、構成を簡略化し、製造コスト低減できる。 Further, since the hinge mechanism 36 also uses one of the pins 42 connecting the baffle 41 as a rotating shaft, the configuration can be simplified and the manufacturing cost can be reduced.

さらに、ヒンジ機構36のヒンジ片52を、バッフル41に当接するかわずかな間隔を介して対向させ、器具本体12の長手方向について制光体18を位置決めする位置決め機構として兼用するため、構成を簡略化し、製造コスト低減できる。また、この位置決め機構としてのヒンジ片52は、長さ寸法を調整することにより、両端部をバッフル41に対向させることができ、バッフル41の位置を自由に設定でき、例えば、等間隔に配置することもできる。また、１個のヒンジ片52の両端部により位置決めする他、複数のヒンジ片52の互いに反体側の端部をそれぞれバッフル41に対向させることにより、制光体18を位置決めすることもできる。 In addition, the hinge piece 52 of the hinge mechanism 36 abuts against the baffle 41 or is opposed to the baffle 41 with a slight interval, and is also used as a positioning mechanism for positioning the light control body 18 in the longitudinal direction of the instrument body 12, thus simplifying the configuration Manufacturing cost can be reduced. Further, the hinge piece 52 as the positioning mechanism can have both ends opposed to the baffle 41 by adjusting the length dimension, and the position of the baffle 41 can be freely set, for example, arranged at equal intervals. You can also. In addition to positioning by both ends of one hinge piece 52, the light control body 18 can also be positioned by making the opposite ends of the plurality of hinge pieces 52 face the baffle 41, respectively.

また、点灯装置14及びランプソケット15は、器具本体12に、いずれも下側からの作業によりねじなどの固定具22，29で取り付けられているとともに、配線23，24，32は互いにコネクタ23a，24a，32aで接続されている。そこで、制光体18を開いた状態で、ランプＬや反射板16を取り外せば、コネクタ23a，24a，32aを外し下側からねじを外すのみで点灯装置14及びランプソケット15の交換などの保守作業が容易にでき、保守作業の作業性を向上できる。 In addition, the lighting device 14 and the lamp socket 15 are each attached to the fixture main body 12 with fixing tools 22 and 29 such as screws by work from below, and the wirings 23, 24, and 32 are connected to each other with connectors 23a, Connected by 24a and 32a. Therefore, if the lamp L and the reflector 16 are removed with the light control body 18 open, maintenance such as replacement of the lighting device 14 and the lamp socket 15 is performed simply by removing the connectors 23a, 24a and 32a and removing the screws from the lower side. Work can be facilitated, and maintenance workability can be improved.

なお、係合保持機構は、上記の構成のラッチ機構38に限られず、制光体18を器具本体12に係脱可能に保持するものであれば良い。また、制光体18を器具本体12に固定するため、ねじなどの固定具を用いることもできる。 Note that the engagement holding mechanism is not limited to the latch mechanism 38 having the above-described configuration, and any engagement holding mechanism may be used as long as the light control body 18 is detachably held on the instrument body 12. Moreover, in order to fix the light control body 18 to the instrument body 12, a fixing tool such as a screw can be used.
