Therefore, the manufacturing cost can be reduced and the reliability can be improved by the strong structure.

すなわち、反射板本体41の端部を端板本体部61の端板部64に当接し、反射板本体41から突設された端部爪部48を挿入口84に挿入し屈曲すなわちかしめて係止受部88に係止して抜け止めすることにより、反射板12と端板14とを容易に固定できる。すなわち、この状態で、端部爪部48と係止受部88との係合により、反射板12の反挿入方向すなわち端板14が抜ける方向にかかる引張力に対する保持力を確保できる。 That is, the end portion of the reflector plate body 41 is brought into contact with the end plate portion 64 of the end plate body portion 61, and the end claw portion 48 protruding from the reflector plate body 41 is inserted into the insertion port 84 and bent, ie, caulked. The reflector 12 and the end plate 14 can be easily fixed by engaging with the stopper portion 88 to prevent the stopper plate 88 from coming off. That is, in this state, the holding force against the tensile force applied in the anti-insertion direction of the reflecting plate 12, that is, the direction in which the end plate 14 is pulled out can be secured by the engagement between the end claw portion 48 and the locking receiving portion 88.

さらに、この状態で、補強部62の補強面75，76が反射板本体41に面状に当接し、この補強部62が端板本体部61から端板部64の面に沿った方向に対して交差する方向すなわち垂直方向の力を受け止めることにより、輸送時や施工時の不用意な扱いにより端板に大きな力が加わった場合にも、端板14の損傷や端板14と反射板12との間の隙間の発生による外観の悪化を防止できる。すなわち、端板14の挿入方向に対し、垂直方向の強度を確保するため、反射板12の両端部及び中心部をサポートするコアを端板14に設け、垂直方向にかかる力に対する応力に対する強度を確保した。 Further, in this state, the reinforcing surfaces 75 and 76 of the reinforcing portion 62 abut on the reflector main body 41 in a planar shape, and the reinforcing portion 62 extends in the direction along the surface of the end plate portion 64 from the end plate main body portion 61. Even if a large force is applied to the end plate due to careless handling during transportation or construction, the end plate 14 is damaged or the end plate 14 and the reflecting plate 12 are received. It is possible to prevent deterioration of the appearance due to the generation of a gap between the two. That is, in order to ensure the strength in the vertical direction with respect to the insertion direction of the end plate 14, the end plate 14 is provided with a core that supports both end portions and the center portion of the reflecting plate 12, and the strength against stress applied to the force in the vertical direction is increased. Secured.

また、端板14をモールド材である樹脂にて形成することにより、外観の自由度が向上し、外観を容易に向上できる。例えば、長手方向の端部がＲ形状で厚みのある照明器具の意匠を容易に実現できる。 Further, by forming the end plate 14 from a resin that is a molding material, the degree of freedom in appearance is improved and the appearance can be easily improved. For example, it is possible to easily realize a design of a lighting fixture having a thick end with an R shape in the longitudinal direction.

さらに、樹脂製の端板14にランプソケット35の一部を埋め込み、例えば、図６に示すように、ランプソケット35が蛍光ランプ10の端子のピンを挿入する溝部35aを備えた回転式のランプソケット35である場合には、この溝部35aが露出する範囲で埋め込み、外観を向上できる。 Further, a part of the lamp socket 35 is embedded in the end plate 14 made of resin. For example, as shown in FIG. 6, the lamp socket 35 includes a groove 35a into which a pin of a terminal of the fluorescent lamp 10 is inserted. In the case of the socket 35, the groove 35a can be embedded within the exposed range to improve the appearance.

そして、樹脂製の端板14と金属製の反射板12とをねじなどの別個の部品を用いずに強固に固定することが可能になり、部品点数の削減及び構造及び組み立て作業の簡略化により製造コストを低減できる。 The resin end plate 14 and the metal reflector 12 can be firmly fixed without using separate parts such as screws, and the number of parts can be reduced and the structure and assembly work can be simplified. Manufacturing cost can be reduced.

そして、挿入口84を端板部64と補強面75，76との角部に沿って設け、補強部62には、挿入口84に沿って補強面75，76を凹設した凹設部86を設けたため、凹設部86の両側の段部により端部爪部48が案内され、挿入口84に端部爪部48を挿入する作業を容易にできるとともに、凹設部86は反射板本体41により覆われ、挿入口84が外部に露出する寸法を最小限として、外観を向上できる。すなわち、端部爪部48の挿入を容易にするため、挿入口84を下側に拡大すると、下方から挿入口84の隙間が見えて外観が悪化するおそれがあるが、挿入口84を上側に拡大したため、端部爪部48の挿入を容易にできるとともに、挿入口84の隙間が見えにくくなり、外観を向上できる。 The insertion port 84 is provided along the corner between the end plate portion 64 and the reinforcing surfaces 75 and 76, and the reinforcing portion 62 is provided with a recessed portion 86 in which the reinforcing surfaces 75 and 76 are recessed along the insertion port 84. Therefore, the end claw portion 48 is guided by the step portions on both sides of the recessed portion 86, and the operation of inserting the end claw portion 48 into the insertion port 84 can be facilitated. The external appearance can be improved by minimizing the dimension of the insertion port 84 that is covered with 41 and exposed to the outside. That is, if the insertion slot 84 is enlarged downward to facilitate the insertion of the end claw part 48, the gap of the insertion slot 84 can be seen from below and the appearance may deteriorate. Since it is enlarged, the insertion of the end claw portion 48 can be facilitated, and the gap of the insertion port 84 becomes difficult to see, so that the appearance can be improved.

さらに、挿入口84に連続して、端板14の端板部64の板の厚さ寸法の範囲内において凹設した凹設部86を設け、挿入口84の上側には構造を設けないことにより、端板14を形成するための金型について、挿入口84を形成するために複雑なスライド構造を備える必要がなく、金型の構造を簡略化して、製造コストを低減できる。 Furthermore, a recessed portion 86 that is recessed within the thickness dimension of the end plate portion 64 of the end plate 14 is provided continuously to the insertion port 84, and no structure is provided above the insertion port 84. Therefore, the mold for forming the end plate 14 does not need to have a complicated slide structure for forming the insertion port 84, and the structure of the mold can be simplified and the manufacturing cost can be reduced.

また、爪部42は、反射板本体41の端部から突設された端部爪部48と、反射板本体41の端部近傍から端部爪部48の突設方向と交差する方向に突設された側部爪部49とを備え、端部爪部48は、挿入口84に挿入して係止受部88に係止するとともに、側部爪部49は、屈曲されて補強部62に設けた側部係止受部92に係止するようにしたため、互いに異なる方向に突設された端部爪部48と側部爪部49とを屈曲して係止受部88と側部係止受部92とに係止することにより、互いに異なる方向に係止する締結部を組み合わせて、端板14と反射板12とを強固に固定できる。 Further, the claw portion 42 protrudes in a direction intersecting with the protruding direction of the end claw portion 48 from the end claw portion 48 protruding from the end portion of the reflection plate main body 41 and from the vicinity of the end portion of the reflection plate main body 41. Side claw portion 49 provided, the end claw portion 48 is inserted into the insertion port 84 and locked to the locking receiving portion 88, and the side claw portion 49 is bent to reinforce the reinforcing portion 62. Since the end claw portion 48 and the side claw portion 49 projecting in different directions are bent, the engagement receiving portion 88 and the side portion are bent. By locking to the locking receiving portion 92, the end plate 14 and the reflecting plate 12 can be firmly fixed by combining fastening portions that lock in different directions.

また、反射板12は、複数の平面状の反射面部43，44を備えるものであるが、各反射面部43，44の端部からそれぞれ端部爪部48を突設して端板14に係止することにより、各反射面部43，44と端板14との間に隙間が生じて外観が悪化することを抑制できる。 Further, the reflecting plate 12 includes a plurality of planar reflecting surface portions 43 and 44, and end claw portions 48 project from the end portions of the reflecting surface portions 43 and 44, respectively. By stopping, it can suppress that a clearance gap produces between each reflective surface part 43 and 44 and the end plate 14, and an external appearance deteriorates.

そして、反射板本体41が４つの反射面部43，44を備える本実施の形態では、反射板12の両端部についてそれぞれ、各反射面部43，44の端部の合計４カ所から端部爪部48を突設し、反射板本体41の両側の合計２カ所から側部爪部49を突設し、すなわち合計６カ所から爪部42を突設することにより、反射板12と端板14とを強固に固定できるとともに、各反射面部43，44と端板14との間の隙間を最小限として、外観が悪化することを抑制できる。 In the present embodiment in which the reflector main body 41 includes the four reflecting surface portions 43 and 44, the end claw portions 48 from the total four places of the end portions of the reflecting surface portions 43 and 44, respectively, at both ends of the reflecting plate 12. The side plate 49 is projected from a total of two locations on both sides of the reflector main body 41, that is, the projection 42 is projected from a total of six locations, so that the reflector 12 and the end plate 14 are connected. While being able to fix firmly, the clearance gap between each reflective surface part 43 and 44 and the end plate 14 can be minimized, and it can suppress that an external appearance deteriorates.

また、直管形の２本の蛍光ランプ10を装着するため、長手方向の両端部に２対のランプソケット35を備える本実施の形態の照明器具１では、端板14の中心対照に配置される各ランプソケット35の両側部で、端部爪部48を照明器具１の長手方向に曲げて係止受部88に係止するとともに、照明器具１の幅方向の両端部で側部爪部49を外側から内側に曲げて側部係止受部92に係止することにより、反射板12と端板14とを強固に固定できる。 In addition, in the lighting fixture 1 of the present embodiment having two pairs of lamp sockets 35 at both ends in the longitudinal direction for mounting two straight tube fluorescent lamps 10, they are arranged at the center of the end plate 14. At both sides of each lamp socket 35, the end claw portion 48 is bent in the longitudinal direction of the lighting fixture 1 and locked to the locking receiving portion 88, and the side claw portion at both ends in the width direction of the lighting fixture 1. The reflector 12 and the end plate 14 can be firmly fixed by bending 49 from the outside to the inside and engaging with the side-part engagement receiving part 92.

さらに、側部係止受部92には、屈曲された側部爪部49に当接し、反射板本体41の端部と端板部64とが互いに圧接される方向に側部爪部49を相対的に押圧する圧入リブとなる押圧部96を設けたため、側部爪部49を屈曲して側部係止受部92に係止した状態で、押圧部96が側部爪部49を相対的に押圧して、反射板本体41の端部と端板部64とが互いに圧接される方向に力が加えられる。そこで、反射体12と端板14とをより強固に締結できるとともに、側部爪部49を屈曲して側部係止受部92に係止すると同時に、反射板本体41と端板部64とを密着させて、これら反射板本体41と端板部64との間に隙間ができることを抑制し、組み立て作業を容易にできるとともに外観を向上できる。 Further, the side lock receiving portion 92 is in contact with the bent side claw portion 49, and the side claw portion 49 is provided in a direction in which the end portion of the reflector plate body 41 and the end plate portion 64 are pressed against each other. Since the pressing portion 96 serving as a press-fitting rib for relatively pressing is provided, the pressing portion 96 makes the side claw portion 49 relative to the side claw portion 49 while the side claw portion 49 is bent and locked to the side portion locking receiving portion 92. Thus, a force is applied in the direction in which the end portion of the reflector main body 41 and the end plate portion 64 are pressed against each other. Therefore, the reflector 12 and the end plate 14 can be tightened more firmly, and at the same time the side claw portion 49 is bent and locked to the side lock receiving portion 92, and at the same time, the reflector main body 41 and the end plate portion 64 Can be prevented from forming a gap between the reflector main body 41 and the end plate portion 64, the assembling work can be facilitated and the appearance can be improved.

なお、この押圧部96は、側部爪部49の側縁部に当接する突条としたが、この構成に限られず、単なる突部とすることもできる。また、側部爪部49の係合を円滑にする構成として、押圧部96の端部に傾斜した案内面97を設けたが、この構成に限られず、側部爪部49の側縁部及び押圧部96の少なくとも一方を傾斜面とすることにより、側部爪部49の屈曲に伴い反射板本体41と端板部64とを円滑に密着させることができる。 The pressing portion 96 is a protrusion that contacts the side edge of the side claw portion 49, but is not limited to this configuration, and may be a simple protrusion. Further, as a configuration for facilitating the engagement of the side claw portion 49, the inclined guide surface 97 is provided at the end portion of the pressing portion 96, but is not limited to this configuration, and the side edge portion of the side claw portion 49 and By making at least one of the pressing parts 96 into an inclined surface, the reflector main body 41 and the end plate part 64 can be smoothly brought into close contact with the bending of the side claw part 49.

また、ランプソケット装着部71の背面に誤挿入防止リブ68を設けたため、反射体の組立体に器具本体11を組み合わせる際は、ランプソケット35を端板14の内側すなわち端板部64と外端板部65との間に誤って挿入することを防止できる。なお、この誤挿入防止リブ68の形状は、上記のものに限られないが、外端板部65から離間して形成することにより、外端板部65の形成時の変形、いわゆるひけを抑制して、外観を容易に向上できる。 In addition, since the erroneous insertion prevention rib 68 is provided on the back surface of the lamp socket mounting portion 71, when the fixture body 11 is combined with the reflector assembly, the lamp socket 35 is connected to the inner side of the end plate 14, that is, the end plate portion 64 and the outer end. Incorrect insertion between the plate portion 65 and the plate portion 65 can be prevented. The shape of the erroneous insertion preventing rib 68 is not limited to the above, but by forming it away from the outer end plate portion 65, deformation during the formation of the outer end plate portion 65, so-called sink, is suppressed. Thus, the appearance can be easily improved.

また、爪部42の配置は必ずしも上記のものに限られず、例えば、端部爪部48すなわち係止受部88を反射板12の両端についてそれぞれ２カ所とし、側部爪部49すなわち側部係止受部92を反射板12の両端側についてそれぞれ２カ所とし、すなわち、反射板12の一端について爪部42すなわち締結部をそれぞれ４カ所に設ける構成とすることもできる。 Further, the arrangement of the claw portions 42 is not necessarily limited to that described above. For example, the end claw portions 48, that is, the locking receiving portions 88 are provided at two positions on both ends of the reflection plate 12, and the side claw portions 49, that is, the side portions It is also possible to adopt a configuration in which the stoppers 92 are provided at two positions on both ends of the reflecting plate 12, that is, the claw portions 42, that is, the fastening portions are provided at four positions on one end of the reflecting plate 12, respectively.

また、側部爪部49を係止する側部係止受部92は、補強部側板部91の内側に一対の案内リブ94を突設して形成する他、補強部側板部91に凹部やスリットを形成することもできる。 Further, the side latch receiving portion 92 for locking the side claw portion 49 is formed by projecting a pair of guide ribs 94 on the inner side of the reinforcing portion side plate portion 91, and has a recess or a recess on the reinforcing portion side plate portion 91. A slit can also be formed.

また、端板14の端板部64の内面と外端板部65の外面との間には、下方に向かって接近する形状に抜き勾配が設けられているため、外端板部65の外面が天井面に対して垂直にならない。そこで、複数の照明器具１を長手方向に沿って連結して配置する場合には、突き合わされた外端板部65の外面同士の間に、下方に向かって拡開する隙間が生じ、見栄えが良くない場合がある。この点、端板14の端板部64などには、複雑な形状が設定されているため、抜き勾配を設定しつつ、外端板部65の外面を垂直とする形状設計は制約が多く容易ではないため、製造コストの上昇の原因となる。 In addition, since a draft is provided in a shape approaching downward between the inner surface of the end plate portion 64 of the end plate 14 and the outer surface of the outer end plate portion 65, the outer surface of the outer end plate portion 65 Is not perpendicular to the ceiling. Therefore, when the plurality of lighting fixtures 1 are connected and arranged along the longitudinal direction, a gap that expands downward is generated between the outer surfaces of the butted outer end plate portions 65, and the appearance is improved. May not be good. In this regard, since the end plate portion 64 of the end plate 14 has a complicated shape, the shape design in which the outer surface of the outer end plate portion 65 is vertical while setting the draft is easy and has many restrictions. However, this causes an increase in manufacturing cost.

そこで、樹脂製の端板14と金属製の反射板12とを一体的に組み合わせ、器具本体11と組み合わせた照明器具１において、端板14の内面と反射板12との取付構造すなわち接合状態を工夫し、図１２及び図１３に示すように、端板14の端板本体部61に当接する部分である、反射板12の反射板本体41の端部に、端板14に設定された抜き勾配の角度に応じた角度θだけ垂直線Ｖから傾斜させた傾斜縁98を形成し、この傾斜縁98で端板14を支持することにより、端板14の外端板部65の外面を、水平な第２の反射面部44すなわち天井面Ｃに対して容易に垂直あるいは略垂直に支持することができる。 Therefore, in the lighting fixture 1 in which the resin end plate 14 and the metal reflecting plate 12 are integrally combined, and the fixture main body 11 is combined, the mounting structure, that is, the joining state between the inner surface of the end plate 14 and the reflecting plate 12 is changed. 12 and 13, as shown in FIG. 12 and FIG. 13, the end plate 14 is set at the end of the reflecting plate main body 41 of the reflecting plate 12, which is the portion that contacts the end plate main body 61. By forming an inclined edge 98 inclined from the vertical line V by an angle θ corresponding to the angle of inclination, and supporting the end plate 14 with the inclined edge 98, the outer surface of the outer end plate portion 65 of the end plate 14 is It can be easily supported vertically or substantially perpendicular to the horizontal second reflecting surface portion 44, that is, the ceiling surface C.

このようにして、端板14の外端板部65の外面を垂直とすることにより、複数の照明器具１を天井面に連結取り付けした際にも、端板14同士の間の角度のついた隙間の発生を抑制し、外観を向上できる。さらに、金属製の反射板12の傾斜縁98の設計は、端板14の設計よりも容易であり、製造コストを低減できる。 In this way, by making the outer surface of the outer end plate portion 65 of the end plate 14 vertical, even when the plurality of lighting fixtures 1 are connected to the ceiling surface, the angle between the end plates 14 is increased. The appearance can be improved by suppressing the generation of gaps. Furthermore, the design of the inclined edge 98 of the metallic reflector 12 is easier than the design of the end plate 14, and the manufacturing cost can be reduced.

本発明は、例えば、オフィスや店舗の天井面に直付け設置される照明器具に適用できる。 The present invention can be applied to, for example, a lighting fixture installed directly on a ceiling surface of an office or a store.
