Description

この発明は、照明器具の器具本体に反射板の取付金具を取り付ける構造に関する。 The present invention relates to a structure for attaching a reflector fitting to a fixture body of a lighting fixture.

従来では、特開２０００−２３１８２０号公報に示すような、器具本体と反射板を取り付ける構造を採用している。特開２０００−２３１８２０号公報では、器具本体端板を内側にたわませ、反射板取付金具の舌片を、器具本体側板に形成された角穴に両側から差し込み取り付ける。反射板は、器具本体に取り付けられた反射板取付金具に着脱自在な係止具にて取り付けられる。 Conventionally, the structure which attaches an instrument main body and a reflecting plate as shown to Unexamined-Japanese-Patent No. 2000-231820 is employ | adopted. In Japanese Patent Application Laid-Open No. 2000-231820, an instrument body end plate is bent inward, and a tongue piece of a reflector mounting bracket is inserted and attached to a square hole formed in the instrument body side plate from both sides. The reflector is attached to a reflector fitting that is attached to the instrument body with a detachable locking tool.

特開２０００−２３１８２０号公報JP 2000-231820 A

特開２０００−２３１８２０号公報のような器具本体側板への反射板取付金具の取付構造では、照明器具本体の端板に形成された角穴は、反射板取付金具の舌片が貫通するために、舌片よりも大きいことが必要である。このため、穴と舌片との間に嵌合時に「隙間」が発生することは避けられない。このため反射板取付金具を介して照明器具本体と反射板との導通を目的とする場合、器具本体が塗装品で塗膜がある場合や、角穴抜き部、反射板取付金具に絶縁皮膜などが有る場合は、確実な導通が出来ない。 In the mounting structure of the reflector mounting bracket to the fixture body side plate as disclosed in Japanese Patent Laid-Open No. 2000-231820, the square hole formed in the end plate of the lighting fixture body passes through the tongue piece of the reflector mounting fixture. It needs to be larger than the tongue piece. For this reason, it is inevitable that a “gap” is generated between the hole and the tongue piece during fitting. For this reason, if the purpose is to connect the luminaire body to the reflector through the reflector mounting bracket, the fixture body may be a painted product with a coating film, or a square hole punched part, an insulating coating on the reflector mounting bracket, etc. If there is, there is no reliable conduction.

また、この「隙間」の発生により、係止具で反射板を反射板取付具に取り付けた場合、照明器具本体と反射板取付金具との間で、がたつきを生じるという課題がある。 In addition, due to the occurrence of the “gap”, there is a problem that when the reflector is attached to the reflector plate fixture with the locking tool, rattling occurs between the luminaire main body and the reflector plate fitting.

この発明は、照明器具において、反射板取付金具と器具本体との導通を確実にすると共に、反射板取付金具と器具本体との間にがたつきの発生のない照明器具の提供を目的とする。 An object of the present invention is to provide a lighting fixture in a lighting fixture that ensures conduction between the reflector mounting bracket and the fixture main body and that does not cause rattling between the reflector mounting fixture and the fixture main body.

図２に示すように、器具本体１０には、蛍光ランプ１１０と平行に延びる器具本体側板に、反射板取付金具を取り付ける角穴が１面に２ヶ所形成（例えば角穴１１１、角穴１１１−１）されている。反射板取付金具２０は、角穴１１１、１１２に取り付けられ、反射板取付金具２０−１は、角穴１１１−１、１１２−１に取り付けられる。 As shown in FIG. 2, the instrument body 10 is formed with two square holes on one side of the instrument body side plate extending in parallel with the fluorescent lamp 110 (for example, square holes 111 and 111 − 1) has been done. The reflector mounting bracket 20 is mounted in the square holes 111 and 112, and the reflector mounting bracket 20-1 is mounted in the square holes 111-1 and 112-1.

（器具本体１０の構造）
図３は、器具本体１０の断面と反射板取付金具２０との斜視図である。器具本体１０は、長手方向に延びる底面１３と、底面１３の長手方向に延びる一端から起立する器具本体側板１１（第１の側板）と、底面１３の長手方向に延びる他端から起立する器具本体側板１２（第１の側板）とを有する。 (Structure of the instrument body 10)
FIG. 3 is a perspective view of the cross section of the instrument body 10 and the reflector mounting bracket 20. The instrument body 10 includes a bottom surface 13 extending in the longitudinal direction, an instrument body side plate 11 (first side plate) standing up from one end extending in the longitudinal direction of the bottom surface 13, and an instrument body standing up from the other end extending in the longitudinal direction of the bottom surface 13. Side plate 12 (first side plate).

（角穴の形状）
図３に示すように、器具本体側板１１には、起立方向の上部に角穴１１１（第１の角穴）が長手方向に形成されている。また、器具本体側板１２には、起立方向の上部に角穴１１２（第２の角穴）が長手方向に形成されている。 (Square hole shape)
As shown in FIG. 3, the instrument body side plate 11 has a square hole 111 (first square hole) formed in the longitudinal direction at the upper part in the standing direction. Further, the instrument body side plate 12 is formed with a square hole 112 (second square hole) in the longitudinal direction at the upper part in the standing direction.

（角穴側凸部）
角穴１１１の縁の一部には、凸形状に凸部１１１ａが形成されている。同様に、角穴１１２の縁の一部にも、凸形状に凸部１１２ａが形成されている。後述のように、凸部１１１ａ、凸部１１２ａは、反射板取付金具２０が取り付け位置の方向にスライドされたときに、反射板取付金具２０の凸部２１１、２２１とこすれ合う。具体的には、凸部１１１ａは凸部２１１とこすれ合い、凸部１１２ａは凸部２２１とこすれ合う。 (Square hole convex part)
A convex portion 111 a is formed in a convex shape at a part of the edge of the square hole 111. Similarly, a convex portion 112 a is also formed in a convex shape at a part of the edge of the square hole 112. As will be described later, the convex portions 111a and the convex portions 112a rub against the convex portions 211 and 221 of the reflective plate mounting bracket 20 when the reflective plate mounting bracket 20 is slid in the mounting position direction. Specifically, the convex portion 111 a rubs with the convex portion 211, and the convex portion 112 a rubs with the convex portion 221.

（戻り止め）
また、角穴１１１の縁には、舌片２１が取付位置までスライドされたときに、舌片２１がスライドされた方向と反対方向への戻りを抑える戻り止め１１１ｂが形成されている。同様に、角穴１１２の縁には、舌片２２が取付位置までスライドされたときに、舌片２２がスライドされた方向と反対方向への戻りを抑える戻り止め１１２ｂが形成されている。 (Detentive)
In addition, a detent 111b is formed at the edge of the square hole 111 to suppress a return in the direction opposite to the direction in which the tongue piece 21 is slid when the tongue piece 21 is slid to the mounting position. Similarly, a detent 112b is formed at the edge of the square hole 112 to suppress the return in the direction opposite to the direction in which the tongue piece 22 is slid when the tongue piece 22 is slid to the mounting position.

（反射板取付金具２０の構造）
図４は、角穴１１１、１１２に取り付けられる反射板取付金具２０の斜視図である。反射板取付金具２０−１は反射板取付金具２０と同様の構成なので、反射板取付金具２０について説明する。反射板取付金具２０は、角穴１１１（第１の角穴）に挿入される板状の端部である舌片２１（第１の舌片）と、角穴１１２（第２の角穴）に挿入される板状の端部である舌片２２（第２の舌片）とを有する。また、舌片２１は、後述するように、角穴１１１の縁の一部とこすれ合う凸部２１１を有する。また、舌片２２は、角穴１１２の縁の一部とこすれ合う凸部２２１を有する。 (Structure of reflector mounting bracket 20)
FIG. 4 is a perspective view of the reflector mounting bracket 20 attached to the square holes 111 and 112. Since the reflector mounting bracket 20-1 has the same configuration as the reflector mounting bracket 20, the reflector mounting bracket 20 will be described. The reflector mounting bracket 20 includes a tongue piece 21 (first tongue piece) which is a plate-like end portion inserted into the square hole 111 (first square hole) and a square hole 112 (second square hole). And a tongue piece 22 (second tongue piece) which is a plate-like end portion to be inserted into the plate. Moreover, the tongue piece 21 has the convex part 211 which rubs against a part of edge of the square hole 111 so that it may mention later. The tongue piece 22 has a convex portion 221 that rubs against a part of the edge of the square hole 112.

図５には、器具本体側板１１の角穴１１１と反射板取付金具２０との側面図を示した。 In FIG. 5, the side view of the square hole 111 of the instrument main body side plate 11 and the reflector mounting bracket 20 is shown.

（反射板取付金具２０の取付過程）
次に、図３及び図６〜図８を参照して、器具本体１０への反射板取付金具２０の取り付け過程を説明する。
図６は、角穴１１１の仮止め位置における反射板取付金具２０の断面ＡＡ（図４）の位置を示した図である。
図７は、角穴１１１の取り付け位置における反射板取付金具２０の断面ＡＡ（図４）の位置を示した図である。

Next, with reference to FIG. 3 and FIGS. 6 to 8, the process of attaching the reflector mounting bracket 20 to the instrument body 10 will be described.
FIG. 6 is a view showing the position of the cross section AA (FIG. 4) of the reflector mounting bracket 20 at the temporary fixing position of the square hole 111.
FIG. 7 is a view showing the position of the cross section AA (FIG. 4) of the reflector mounting bracket 20 at the mounting position of the square hole 111.
FIG. 8 is a cross-sectional view AA (FIG. 4) of the reflector mounting bracket 20 showing the process of sliding from the state in which the reflector mounting bracket 20 is in the temporary fixing position to the mounting position in the square hole 111. .

（１）まず、図３の（１）に示すように、器具本体１０の器具本体側板１１と器具本体側板１２とを矢印方向にすぼめる（矢印方向に倒す）。
（２）次に、反射板取付金具２０を角穴１１１、角穴１１２に仮止めする。すなわち、図３において、反射板取付金具２０の舌片２１を外側から角穴１１１に挿入し、また、舌片２２を外側から角穴１１２に挿入して、仮止めする。図６に仮止め状態における反射板取付金具２０の断面ＡＡを示した。これは図８（ａ）の状態である。仮止めされた状態では、反射板取付金具２０は、器具本体１０との導通はされていない。次の（３）で器具本体１０の長手方向に反射板取付金具２０をスライドする事により、強制的に導通する。
（３）仮止め後、仮止め位置から図３の「（３）スライド」のように反射板取付金具２０をスライドさせると（図８（ｂ）、（ｃ）が対応）、図７（図８（ｄ）が対応）に示すように、角穴１１１の戻り止め１１１ｂに反射板取付金具２０の舌片２１の終端部２１２が入る（当接する）。舌片２２と角穴１１２とについても同様である。スライド時には、角穴１１１の縁に設けられた凸部１１１ａと舌片２１の凸部２１１とが嵌合し、導通する。すなわち、図６に示すように、導通の手段として、角穴１１１（角穴１１２についても同様）の舌片２１の取り付け位置に相当する部分における舌片２１の厚みに対応する寸法Ａ２を、舌片２１（角穴１１２では舌片２２）の厚Ａ１みよりも一部分狭くする（Ａ２＜Ａ１）。このとき角穴１１１の寸法の狭い部分は山形の頂点形状であるのが望ましい。なお、この頂点形状は、先端部が角形状でも、Ｒ形状でも良い。 (1) First, as shown to (1) of FIG. 3, the instrument main body side plate 11 and the instrument main body side plate 12 of the instrument main body 10 are squeezed in the arrow direction (fall down in the arrow direction).
(2) Next, the reflector mounting bracket 20 is temporarily fixed to the square hole 111 and the square hole 112. That is, in FIG. 3, the tongue piece 21 of the reflector mounting bracket 20 is inserted into the square hole 111 from the outside, and the tongue piece 22 is inserted into the square hole 112 from the outside to be temporarily fixed. FIG. 6 shows a cross section AA of the reflector mounting bracket 20 in the temporarily fixed state. This is the state of FIG. In the temporarily fixed state, the reflector mounting bracket 20 is not electrically connected to the instrument body 10. In the next (3), the reflector plate fitting 20 is slid in the longitudinal direction of the instrument body 10 to forcibly conduct.
(3) After temporary fixing, when the reflector mounting bracket 20 is slid from the temporary fixing position as shown in “(3) slide” in FIG. 3 (FIGS. 8B and 8C correspond), FIG. 8 (d) corresponds), the terminal portion 212 of the tongue piece 21 of the reflector mounting bracket 20 enters (contacts) the detent 111b of the square hole 111. The same applies to the tongue piece 22 and the square hole 112. At the time of sliding, the convex part 111a provided at the edge of the square hole 111 and the convex part 211 of the tongue piece 21 are fitted and conducted. That is, as shown in FIG. 6, as a means for conduction, a dimension A2 corresponding to the thickness of the tongue piece 21 at a portion corresponding to the attachment position of the tongue piece 21 of the square hole 111 (the same applies to the square hole 112) A part is narrower than the thickness A1 of the piece 21 (the tongue piece 22 in the case of the square hole 112) (A2 <A1). At this time, it is desirable that the narrow portion of the square hole 111 has an angled apex shape. In addition, this apex shape may be a square shape or an R shape at the tip.

このような寸法関係にすることで、図８（ｂ）、（ｃ）に示すように、反射板取付金具２０は、仮止めされた状態から取り付け位置の方向である器具本体１０の長手方向にスライドされると、舌片２１の凸部２１１が角穴１１１を形成する縁の一部に形成された凸部１１１ａとこすれ合いながら移動する。同じように、舌片２２の凸部２２１が前記第２の角穴１１２を形成する縁の一部に形成された凸部１１２ａとこすれ合いながら移動する。反射板取付金具２０は、このようにスライドされることで、舌片２１が角穴１１１の縁によって銜えられて嵌合し、舌片２２が角穴１１２の縁によって銜えられて嵌合する。 With such a dimensional relationship, as shown in FIGS. 8B and 8C, the reflector mounting bracket 20 is moved from the temporarily fixed state to the longitudinal direction of the instrument body 10 which is the direction of the mounting position. When slid, the convex portion 211 of the tongue piece 21 moves while rubbing against the convex portion 111 a formed at a part of the edge forming the square hole 111. Similarly, the convex portion 221 of the tongue piece 22 moves while rubbing with the convex portion 112 a formed at a part of the edge forming the second square hole 112. By sliding the reflector mounting bracket 20 in this manner, the tongue piece 21 is gripped and fitted by the edge of the square hole 111, and the tongue piece 22 is gripped and fitted by the edge of the square hole 112.

このように、反射板取付金具２０の舌片２１，２２は、角穴１１１、角穴１１２とこすれ合うため、器具本体が塗装品で塗膜がある場合や、角穴、反射板取付金具に絶縁皮膜などが有る場合でも、塗膜や皮膜をはがすことにより確実な導通を得ることができる。 Thus, since the tongue pieces 21 and 22 of the reflector mounting bracket 20 rub against the square hole 111 and the square hole 112, when the instrument body is a coated product and has a coating film, Even when an insulating film or the like is present, reliable conduction can be obtained by removing the coating film or the film.

また、図２に示したように、反射板３０は、２個の反射板係止具４０（例えば、ネジ）で反射板取付金具に取り付けられる。反射板３０は、それぞれの反射板係止具４０のネジ部が貫通する穴３１，３２があいている。また、反射板取付金具２０、２０−１には、例えば図４に示すように、反射板係止具４０のネジ部の貫通する穴２３が形成されている。以上の構成において反射板３０を取り付ける場合、反射板取付金具２０、２０−１がこれらの「取り付け位置」（図７の嵌合位置）にある場合にのみ、反射板３０の穴間ピッチＰ１に、射板取付金具２０の穴と、反射板取付金具２０−１の穴との穴間ピッチＰ２が略一致する。つまり、反射板取付金具と器具本体１０とが導通可能な状態でのみ、反射板３０の穴間ピッチＰ１に、２つの反射板取付金具との穴間ピッチＰ２が合う。このため、反射板３０を取り付けできるときは、反射板取付金具と器具本体とがすでに導通可能な状態となっている。また、反射板取付金具２０、２０−１が「取り付け位置」にある場合は、がたのない状態であるので、反射板３０と器具本体とのがたをなくすことができる。 As shown in FIG. 2, the reflecting plate 30 is attached to the reflecting plate mounting bracket by two reflecting plate locking tools 40 (for example, screws). The reflecting plate 30 has holes 31 and 32 through which the screw portions of the reflecting plate locking tools 40 pass. Further, as shown in FIG. 4, for example, as shown in FIG. 4, a hole 23 through which a threaded portion of the reflection plate locking tool 40 passes is formed in the reflection plate mounting brackets 20 and 20-1. When attaching the reflector 30 in the above configuration, the pitch P1 between the holes of the reflector 30 is set only when the reflector fittings 20 and 20-1 are in these “attachment positions” (fitting positions in FIG. 7). The pitch P2 between the holes of the projecting plate mounting bracket 20 and the hole of the reflector mounting bracket 20-1 is substantially the same. That is, the hole pitch P2 between the two reflecting plate mounting brackets matches the hole pitch P1 of the reflecting plate 30 only in a state where the reflecting plate mounting bracket and the instrument body 10 can conduct. For this reason, when the reflecting plate 30 can be mounted, the reflecting plate mounting bracket and the instrument body are already in a conductive state. In addition, when the reflector mounting brackets 20 and 20-1 are in the “attachment position”, since there is no backlash, rattling between the reflector 30 and the instrument body can be eliminated.

以上のように実施の形態１の照明器具１０００は、まず反射板取付金具を器具本体側板の角穴（嵌合時隙間のある部分）に仮取付けしたあとに、器具本体長手側に、スライドし取り付け位置に取り付ける構造である。取り付け位置には反射板取付金具（舌片）との隙間を無くす構造が形成されている。このため、スライドさせることで、器具本体と反射板取付金具とは確実に接触し導通ができる。また、仮止め状態では反射板を取付けようとしても取り付けピッチ（穴間ピッチ）があわないので、導通無しでの反射板の取り付けは起こらないという利点もある。さらに、この構造により、器具本体と反射板取付金具とは隙間無く密着するため、反射板を反射板係止具により取り付けた場合でも、がたつきを生じない効果がある。 As described above, the lighting fixture 1000 of the first embodiment first slides the reflector mounting bracket to the longitudinal side of the fixture body after temporarily attaching the reflector mounting bracket to the square hole (the portion having a gap when fitted) of the fixture body side plate. It is a structure attached to an attachment position. At the mounting position, a structure is formed to eliminate the gap with the reflector mounting bracket (tongue piece). For this reason, by making it slide, the instrument main body and the reflector mounting bracket can reliably contact and conduct. In addition, there is also an advantage that the reflection plate is not attached without conduction because the attachment pitch (inter-hole pitch) does not vary even if the reflection plate is attached in the temporarily fixed state. Furthermore, this structure allows the instrument main body and the reflector mounting bracket to be in close contact with each other without any gap, and therefore has the effect of preventing rattling even when the reflector is attached with the reflector locking member.
