Description

この発明は照明器具の器具本体の構造に関する。 The present invention relates to the structure of a fixture body of a luminaire.

反射板の端部に取り付けられる端板において、反射板に嵌合する突出片に切り起こし片を設け、この切り起こし片を反射板に嵌合させて、端板を反射板に固定する技術がある。（例えば、特許文献１、２参照。）また、端板の突出片を切り起こして傾斜部を形成するようにし、反射板の端部を折り曲げて突出片を挟みこむ技術がある。（例えば、特許文献３参照。）また、端板の突出片の先端を９０°折り曲げて形成し、反射板の端部を折り曲げて突出片を挟みこむ技術がある（例えば、特許文献４参照）。 In the end plate attached to the end of the reflector, a technique of providing a cut-up piece on a protruding piece to be fitted to the reflector, fitting the cut-up piece to the reflector, and fixing the end plate to the reflector. is there. (See, for example, Patent Documents 1 and 2.) Further, there is a technique in which a protruding piece of an end plate is cut up to form an inclined portion, and the end portion of the reflector is bent to sandwich the protruding piece. (See, for example, Patent Document 3.) Further, there is a technique of bending the tip of a protruding piece of an end plate by 90 ° to form the protruding piece, and bending the end of the reflector to sandwich the protruding piece (see, for example, Patent Document 4). ..

特開昭６２−１４３３０３号公報（第１図〜第３図参照。）Japanese Unexamined Patent Publication No. 62-143303 (see FIGS. 1 to 3) 特開昭６２−１４３３０２号公報（第１図〜第３図参照。）Japanese Unexamined Patent Publication No. 62-143302 (see FIGS. 1 to 3) 特開平１１−２５０７１１号公報（図１１、図１２参照。）Japanese Unexamined Patent Publication No. 11-250711 (see FIGS. 11 and 12) 実公平０３−２３６１６号公報（第８図参照。）Jikken 03-23616 (see Fig. 8) 特開２００５−３１７３５６号公報Japanese Unexamined Patent Publication No. 2005-317356 特開２００６−１１８７４３号公報Japanese Unexamined Patent Publication No. 2006-118743

しかしながら、特許文献１、２のように、突出片に切り起こし片を形成する場合、切り起こし片の先端が、反射板の凹部または折り曲げ片に接触するようにするため、反射板の厚さ以内となるように、切り起こし角度を管理しなければならなかった。また、特許文献３、４のように突出片の先端に傾斜部を設けたり、９０°の折り曲げ部を形成したりする場合であっても、反射板側に突出片を挿入するためのガイド部がないために、反射板の端部を折り曲げ加工して、突出片を挟み込むようにするため、突出片が反射板の所定の位置に接触するような精度が求められていた。 However, as in Patent Documents 1 and 2, when a cut-up piece is formed on a protruding piece, the tip of the cut-up piece is within the thickness of the reflector so as to come into contact with the concave portion or the bent piece of the reflector. I had to manage the angle of the cut-up so that it would be. Further, even when an inclined portion is provided at the tip of the protruding piece or a 90 ° bent portion is formed as in Patent Documents 3 and 4, a guide portion for inserting the protruding piece on the reflector side is provided. Therefore, in order to bend the end portion of the reflector so as to sandwich the projecting piece, accuracy is required so that the projecting piece comes into contact with a predetermined position of the reflector.

本発明は、簡単な構成のガイド部を設けるとともに、ガイド部に突出片を挿入する方向とは逆方向の力が加わったときも、突出片がガイド部から外れ難くすることを目的とする。 An object of the present invention is to provide a guide portion having a simple structure and to prevent the protruding piece from coming off from the guide portion even when a force is applied to the guide portion in a direction opposite to the direction in which the protruding piece is inserted.

（端板１２０Ａの取付工程）
次に、端板１２０Ａを本体部１１０に取り付ける工程について説明する。
図８は、端板１２０Ａを本体部１１０に取り付けた状態を部分的に示した斜視図である。まず、組み立て装置（または組み立て作業者）は、本体部１１０の半カール部１１５ｂに、突出片１２２に挿入する。このとき、半カール部１１５ｂと立上部１１４の内壁１１４−１との間の隙間（図５の隙間Ｗ）に突出傾斜部１２２ｂの先端が入り込む（接触する）ことにより、隙間Ｗは、組み立て装置（または組み立て作業者）が突出片１２２を半カール部１１５ｂに挿入する際のガイドの機能を果たす。 (Mounting process of end plate 120A)
Next, a step of attaching the end plate 120A to the main body 110 will be described.
FIG. 8 is a perspective view partially showing a state in which the end plate 120A is attached to the main body 110. First, the assembly device (or assembly worker) is a semi-curled portion 115b of the main body portion 110, to be inserted into the projecting piece 122. At this time, the tip of the protruding inclined portion 122b enters (contacts) the gap (gap W in FIG. 5) between the half-curled portion 115b and the inner wall 114-1 of the rising portion 114, so that the gap W is formed by the assembling device. (Or an assembler) serves as a guide when inserting the projecting piece 122 into the semi-curled portion 115b.

さらに、組み立て装置（または組み立て作業者）が端板１２０Ａを本体部１１０に密着するように押すと、突出片１２２の先端（突出傾斜部１２２ｂ）は、半カール部１１５ｂをつき抜け（図９）、半カール部１１５ｂとカール処理部１１５ａとの間に露出する。この状態となったとき、組み立て装置によって半カール部１１５ｂを押しつぶすと、半カール部１１５ｂは延出部１２２ａを立上部１１４の内壁１１４−１との間で挟み込む。半カール部１１５ｂが押しつぶされることによって、挿入方向における延出部１２２ａの先端部である突出傾斜部１２２ｂは、突出片１２２を半カール部１１５ｂへ挿入した方向とは逆方向へスライドすることができなくなる。 Further, when the assembling device (or the assembling worker) pushes the end plate 120A so as to be in close contact with the main body 110, the tip of the protruding piece 122 (protruding inclined portion 122b) passes through the half-curled portion 115b (FIG. 9). , It is exposed between the half curl portion 115b and the curl processing portion 115a. In this state, when the half-curl portion 115b is crushed by the assembling device, the half-curl portion 115b sandwiches the extension portion 122a with the inner wall 114-1 of the rising portion 114. By crushing the half-curled portion 115b, the protruding inclined portion 122b, which is the tip of the extending portion 122a in the insertion direction, can slide in the direction opposite to the direction in which the protruding piece 122 is inserted into the half-curled portion 115b. It disappears.

このように、端板１２０Ａを本体部１１０に密着させたとき、接触片１２３は、傾斜部１１３の内壁に接触し、凸部１２４は、接触部１１２の内壁及び凹部側壁部１１１ａの内壁に接触した状態となる（図８のＡ部）。 In this way, when the end plate 120A is brought into close contact with the main body 110, the contact piece 123 contacts the inner wall of the inclined portion 113, and the convex portion 124 contacts the inner wall of the contact portion 112 and the inner wall of the concave side wall portion 111a. (Part A in FIG. 8).

次に、切起片１１１ａａを９０°外側へ折り曲げると、切起片１１１ａａは保持部１２４ｂに接触する。このように切起片１１１ａａを折り曲げて保持部１２４ｂに接触させると、凸部１２４と接触部１１２の密着性が向上する。しかも、保持部１２４ｂは板厚方向に対して切起片１１１ａａと接触部１１２に直角方向に接触するので、切起片１１１ａａの折り曲げによる力が保持部１２４ｂ、接触部１１２に伝わりやすくなる。 Next, when the cut-up piece 111aa is bent 90 ° outward, the cut-up piece 111aa comes into contact with the holding portion 124b. When the cut-up piece 111aa is bent and brought into contact with the holding portion 124b in this way, the adhesion between the convex portion 124 and the contact portion 112 is improved. Moreover, since the holding portion 124b comes into contact with the cut-up piece 111aa and the contact portion 112 in the direction perpendicular to the plate thickness direction, the force due to the bending of the cut-up piece 111aa is easily transmitted to the holding portion 124b and the contact portion 112.

さらに、切起片１１１ａａが保持部１２４ｂに接触した状態となったとき、切起片１１１ａａと保持部１２４ｂの端部である引っ掛かり部１２４ｃが接するようになる。したがって、端板１２０Ａを本体部１１０に押し込んだ方向とは逆方向に端板１２０Ａがスライドするのを防止することができる。 Further, when the cut-up piece 111aa comes into contact with the holding portion 124b, the cut-up piece 111aa and the hooking portion 124c, which is the end of the holding portion 124b, come into contact with each other. Therefore, it is possible to prevent the end plate 120A from sliding in the direction opposite to the direction in which the end plate 120A is pushed into the main body 110.

また、突出片１２２、接触片１２３、凸部１２４が本体部１１０の内面に密着して接触・支持するので、本体部１１０の撓みを防止することができ、本体部１１０の変形などに対する補強の効果がある。 Further, since the projecting piece 122, the contact piece 123, and the convex portion 124 are in close contact with and support the inner surface of the main body portion 110, it is possible to prevent the main body portion 110 from bending and to reinforce the main body portion 110 against deformation and the like. effective.

実施の形態１によれば、反射板（本体部１１０）に突出片を挿入するためのガイド部（半カール部）を設けた。また、反射板の端部の折り曲げ加工（半カールの圧接）を、突出片を挟みこんだ後、圧接する。これによりガイド部に突出片を挿入する方向とは逆方向の力が加わったときも、突出片がガイド部から外れ難くすることができる。 According to the first embodiment, a guide portion (semi-curled portion) for inserting the projecting piece is provided in the reflector (main body portion 110). Further, the end portion of the reflector is bent (half-curl pressure welding) after sandwiching the protruding piece. As a result, even when a force is applied in the direction opposite to the direction in which the protruding piece is inserted into the guide portion, the protruding piece can be made difficult to come off from the guide portion.

実施の形態２．
本実施の形態２は、実施の形態１の突出片１２２の変形例である。本実施の形態２は、実施の形態１における突出傾斜部１２２ｂとは別の突出傾斜部に関する実施の形態である。突出傾斜部の他は実施の形態１と同じである。本実施の形態２では、実施の形態１と異なる特徴部分である端板（突出片）のみについて説明する。突出片の形状の異なる実施の形態２の端板を端板１２０Ｂと記す。 Embodiment 2.
The second embodiment is a modification of the protruding piece 122 of the first embodiment. The second embodiment is an embodiment relating to a protruding inclined portion different from the protruding inclined portion 122b in the first embodiment. It is the same as the first embodiment except for the protruding inclined portion. In the second embodiment, only the end plate (protruding piece), which is a feature portion different from that of the first embodiment, will be described. The end plate of the second embodiment having a different shape of the protruding piece is referred to as an end plate 120B.

FIG. 12 is a perspective view partially showing a state in which the end plate 120B is attached to the main body 110. FIG. 13 is an enlarged view of D in the inserted state of the end plate 120B in FIG.

（突出傾斜部１２２ｃ）
端板１２０Ｂの突出傾斜部１２２ｃは、実施の形態１の突出傾斜部１２２ｂと以下の相違がある。実施の形態１の突出傾斜部１２２ｂは、図９の矢印Ｙ１の方向に折り曲げられていた。つまり折り曲げの軸Ｙ２は、立上部１１４の立ち上がり方向１１４−１（図９）であった。これに対して実施の形態２の突出傾斜部１２２ｃは矢印Ｚ１（図１１）の方向に、お辞儀をするように折り曲げられており、折り曲げの軸は突出片１２２の半カール部１１５ｂへの挿入方向（図１３）となっている。なお、突出傾斜部１２２ｃは突出傾斜部１２２ｂと同様に、半カール部１１５ｂに挿入前の、単品の状態で、既に折り曲げられている。 (Protruding inclined portion 122c)
The protruding inclined portion 122c of the end plate 120B has the following differences from the protruding inclined portion 122b of the first embodiment. The protruding inclined portion 122b of the first embodiment was bent in the direction of the arrow Y1 in FIG. That is, the bending axis Y2 was in the rising direction 114-1 (FIG. 9) of the rising portion 114. On the other hand, the protruding inclined portion 122c of the second embodiment is bent in the direction of arrow Z1 (FIG. 11) so as to bow, and the bending axis is the insertion direction of the protruding piece 122 into the half curled portion 115b. (Fig. 13). Like the protruding inclined portion 122b, the protruding inclined portion 122c has already been bent in a single item state before being inserted into the half-curled portion 115b.

次に、端板１２０Ｂを本体部１１０に取り付ける工程について説明する。実施の形態２の突出傾斜部１２２ｃは、半カール部１１５ｂがカール状に形成された内側の曲面内側１１５ａ−１（図５）を通過する。 Next, a step of attaching the end plate 120B to the main body 110 will be described. The protruding inclined portion 122c of the second embodiment passes through the inner curved surface side 115 a- 1 (FIG. 5) in which the semi-curled portion 115b is formed in a curled shape.

このように、突出傾斜部１２２ｃが半カール部１１５ｂの曲面内側１１５ａ−１を通過し、半カール部１１５ｂとカール処理部１１５ａとの間に露出する。よって、突出片１２２を突出傾斜部１２２ｃがガイドすることができる。そして、半カール部１１５ｂが押しつぶされると、半カール部１１５ｂが形成する曲面がなくなるので、カール処理部１１５ａの方向に露出した突出傾斜部１２２ｃは半カール部１１５ｂの端部に引っ掛かる。このため、突出片１２２が半カール部１１５ｂから外れることがない。 In this way, the protruding inclined portion 122c passes through the curved surface inner side 115 a- 1 of the half curl portion 115b and is exposed between the half curl portion 115b and the curl processing portion 115a. Therefore, the protruding piece 122 can be guided by the protruding inclined portion 122c. Then, when the half-curl portion 115b is crushed, the curved surface formed by the half-curl portion 115b disappears, so that the protruding inclined portion 122c exposed in the direction of the curl processing portion 115a is caught by the end portion of the half-curl portion 115b. Therefore, the protruding piece 122 does not come off from the half-curled portion 115b.
