Description

本発明は、光源を有した灯具の向きを自在に可変して光の照射方向を調節できる読書灯等の照明器具に関する。   The present invention relates to a lighting fixture such as a reading lamp that can freely change the direction of a lamp having a light source and adjust the light irradiation direction.

従来、器具本体が有した円形開口の縁に、光源が内蔵された略球状の灯具を載置し、弾性部材が有した一対の固定部を器具本体に固定させて、弾性部材の押さえ部を灯具の背面に当接させることにより、灯具を上方から押えて灯具の器具本体への取付けと灯具の照射方向の保持とを実現したダウンライトが知られている（例えば、特許文献１参照。）。   Conventionally, a substantially spherical lamp with a built-in light source is placed on the edge of the circular opening of the instrument body, and a pair of fixing parts of the elastic member are fixed to the instrument body, so that the holding part of the elastic member is A downlight is known in which a lamp is pressed from above to achieve attachment of the lamp to the fixture body and holding of the irradiation direction of the lamp by bringing the lamp into contact with the back surface (see, for example, Patent Document 1). .

このダウンライトでは、器具本体の円形開口の縁とこれに押付けられた灯具との間の摩擦力、及び灯具とこれに弾性的に接した押さえ部との間の摩擦力により、灯具を静止状態に保持できる。これとともに、器具本体の円形開口の下側から灯具を前記摩擦力に抗して回転操作して、灯具の向きを任意に変えることにより、灯具からの光の照射方向を調節できる。
特開2005−149790号公報（段落0013−0019、図１−図５） In this downlight, the lamp is kept stationary by the frictional force between the edge of the circular opening of the fixture body and the lamp pressed against it, and the frictional force between the lamp and the pressing part elastically contacting the lamp. Can be retained. At the same time, the lighting direction of the light from the lamp can be adjusted by rotating the lamp against the frictional force from the lower side of the circular opening of the fixture body and arbitrarily changing the direction of the lamp.
Japanese Patent Laying-Open No. 2005-149790 (paragraphs 0013-0019, FIGS. 1 to 5)

特許文献１の照明器具は、その灯体が押込まれた場合、押込まれた灯体を弾性部材のみで受止める構成である。このため、照明器具を設置する際に灯具の回転状態を確認する際や実際の使用時等に、誤って灯体が過度に押込まれることがあると、弾性部材の特に押さえ部が過度に変形して、永久変形を起こす恐れがある。このようなことは照明器具がダウンライトではなく、その灯具が押される可能性が高い条件で使用される場合により顕在化する。そして、弾性部材が永久変形すると、灯具を所定の力で押せなくなるに伴い、灯具を調節した向きに保持する性能が低下して、照射方向を保持し難くなる。   The lighting fixture of patent document 1 is the structure which receives the pushed lamp body only by an elastic member, when the lamp body is pushed. For this reason, when checking the rotation state of the lamp when installing the luminaire or during actual use, etc., if the lamp is accidentally pushed excessively, especially the holding part of the elastic member will be excessive. Deformation may cause permanent deformation. This is more apparent when the lighting fixture is not a downlight and is used in a condition where the lamp is likely to be pressed. When the elastic member is permanently deformed, as the lamp cannot be pushed with a predetermined force, the performance of holding the lamp in the adjusted direction is lowered, and it becomes difficult to hold the irradiation direction.

本発明の目的は、灯具が過度に押込まれてもこの灯具を付勢する弾性部材が永久変形しないようにした照明器具を提供することにある。   An object of the present invention is to provide a lighting fixture in which an elastic member that biases the lamp is not permanently deformed even when the lamp is excessively pushed.

請求項1の発明は、光源が内蔵された灯具であって、この灯具の正面側部位が半球状外面を有し、かつ、前記灯具の背面側部位が球面の一部からなる背面を有した前記灯具と；複数の部材取付け部を有するとともに前記半球状外面の最大径より小径な開口を有し、この開口の縁で前記半球状外面を受けて前記灯具による照射方向を可変できるように前記灯具を変向可能に支持する器具本体と；前記部材取付け部に取付けられる複数の固定部、及びこれら固定部間にわたって設けられて前記背面に弾性的に接する押圧部を有して、前記灯具を前記開口の縁に押付ける弾性材製の押圧部材と；前記器具本体に固定的に設けられ前記灯具が前記押圧部材方向へ押込み移動された際に移動される灯具を受止めるストッパと；を具備したことを特徴としている。   The invention of claim 1 is a lamp with a built-in light source, wherein a front side portion of the lamp has a hemispherical outer surface, and a rear side portion of the lamp has a back surface formed of a part of a spherical surface. The lamp; having a plurality of member mounting portions and an opening having a diameter smaller than the maximum diameter of the hemispherical outer surface, and receiving the hemispheric outer surface at an edge of the opening so that the irradiation direction by the lamp can be changed. An instrument main body that supports the lamp so that it can be turned; a plurality of fixing parts that are attached to the member attaching part; and a pressing part that is provided between the fixing parts and elastically contacts the back surface. A pressing member made of an elastic material that presses against an edge of the opening; and a stopper that is fixedly provided on the instrument body and receives the lamp that is moved when the lamp is pushed and moved toward the pressing member. As a feature Yes.

請求項１の発明で、器具本体の開口は、その全周縁で灯具の半球状外面を支持することが好ましいが、開口縁の周方向に沿ってこの縁の一部をなす支持凸部を三箇所以上間隔的に好ましくは等間隔に設け、これら支持凸部に灯具の半球状外面を支持させることもできる。請求項１の発明で、半球状外面の頂部に出射凸部を突設して、この凸部を通して光源が発した光を出射させてもよく、又、出射凸部を除去して半球状外面の頂部を通して光源が発した光を出射させてもよい。請求項１の発明で、光源には、発光ダイオード以外のランプを用いることが可能である。請求項１の発明で、ストッパは、器具本体の外側から内側にねじ込まれて器具本体内に突出する複数のねじで形成できるとともに、器具本体からその内側に起こされた複数の切起こし部で形成することもでき、これらの場合できる限り多くのストッパを設けるとよい。又、ストッパが器具本体とは別部品からなる場合、このストッパは器具本体の中心軸線が延びる方向に多少がたつくことが可能に設けられていてもよい。   In the invention of claim 1, it is preferable that the opening of the fixture body supports the hemispherical outer surface of the lamp at the entire periphery thereof. However, there are three supporting protrusions forming a part of the edge along the circumferential direction of the opening edge. It is also possible to provide at equal intervals or more, preferably at equal intervals, and to support the hemispherical outer surface of the lamp on these support convex portions. In the invention of claim 1, an output convex portion may be provided on the top of the hemispherical outer surface, and the light emitted from the light source may be emitted through the convex portion, or the hemispherical outer surface may be removed by removing the output convex portion. The light emitted from the light source may be emitted through the top of the light source. In the invention of claim 1, a lamp other than the light emitting diode can be used as the light source. In the first aspect of the invention, the stopper can be formed by a plurality of screws that are screwed inwardly from the outside of the instrument body and project into the instrument body, and formed by a plurality of cut-and-raised portions raised from the instrument body to the inside thereof. It is also possible to provide as many stoppers as possible in these cases. In addition, when the stopper is formed of a separate part from the instrument body, this stopper may be provided so that it can be somewhat loose in the direction in which the central axis of the instrument body extends.

請求項１の発明では、通常、押圧部の弾性力で灯具が器具本体の開口の縁に押付けられているので、灯具はストッパから離間している。これにより、灯具が変向操作されることに伴う灯具の動きをストッパが妨げないので、灯具の向きを変えて光の照射方向を任意に調節できる。そして、誤って灯具が過大な力で押込まれた場合、灯具がストッパに受止められるので、それ以上、灯具が押込まれないようにできる。これにより、灯具を器具本体の開口に向けて付勢している弾性部材の押圧部に過大な押込み荷重の全てが作用することがなくなり、弾性部材が永久変形しないようにできる。   In the invention of claim 1, since the lamp is normally pressed against the edge of the opening of the instrument body by the elastic force of the pressing portion, the lamp is separated from the stopper. Thereby, since the stopper does not hinder the movement of the lamp due to the turning operation of the lamp, it is possible to arbitrarily adjust the light irradiation direction by changing the direction of the lamp. If the lamp is accidentally pushed in with an excessive force, the lamp is received by the stopper, so that the lamp can be prevented from being pushed any further. As a result, it is possible to prevent all of the excessive pressing load from acting on the pressing portion of the elastic member urging the lamp toward the opening of the fixture body, and the elastic member can be prevented from being permanently deformed.

請求項２の発明は、前記ストッパを前記器具本体の内部に取付けたリングで形成したことを特徴としている。   The invention of claim 2 is characterized in that the stopper is formed by a ring attached inside the instrument body.

この発明では、灯具が過度に押し込まれる方向がいかなる方向であっても、押込まれた灯具をストッパで確実に受止めることができる。   According to the present invention, the pushed lamp can be reliably received by the stopper regardless of the direction in which the lamp is pushed excessively.

請求項１の発明によれば、灯具が過度に押込まれた場合に、この灯具を付勢する弾性部材に押込み荷重の全てが作用することがないので、弾性部材の永久変形を防止することが可能な照明器具を提供できる。   According to the first aspect of the present invention, when the lamp is excessively pressed, not all of the pressing load acts on the elastic member that urges the lamp, so that it is possible to prevent permanent deformation of the elastic member. Possible lighting fixtures can be provided.

請求項２の発明によれば、灯具が過度に押し込まれる方向がいかなる方向であっても、押込まれた灯具をストッパで確実に受止めて、弾性部材が永久変形しないようにできる。   According to the second aspect of the present invention, it is possible to reliably receive the pushed lamp with the stopper and prevent the elastic member from being permanently deformed, regardless of the direction in which the lamp is pushed excessively.

図１〜図８を参照して本発明の一実施形態を説明する。この実施形態の照明器具は読書灯１として使用される。即ち、例えば客車、航空機の客室、客船等の輸送体内の通路の少なくとも片側に座席が、通路が延びる方向に沿って並べて配置され、これらの座席が有した背凭れの上端部でかつ背凭れの幅方向一端部、言い換えれば、座席肩部に、読書灯１が設置されている。この場合、通路側と窓側に並べられている一対の座席のうちで、通路側の座席については通路側の座席肩部に読書灯１が設置され、又、窓側の座席については窓側の座席肩部に読書灯１が設置される。読書灯１は、座席に着座した乗客が読書をする場合に、乗客の肩越しから手元を向けて光をスポット的に投光して照明する。   An embodiment of the present invention will be described with reference to FIGS. The lighting fixture of this embodiment is used as a reading lamp 1. That is, for example, seats are arranged side by side along the direction in which the passage extends in at least one side of a passage in a transport body such as a passenger car, an aircraft cabin, a passenger ship, and the like. The reading lamp 1 is installed at one end in the width direction, in other words, at the seat shoulder. In this case, among the pair of seats arranged on the aisle side and the window side, the reading lamp 1 is installed on the aisle seat shoulder for the aisle seat, and the window side seat shoulder for the window side seat Reading lamp 1 is installed in the department. When a passenger sitting on a seat reads a book, the reading lamp 1 projects light by spotting light from the passenger's shoulder over his / her shoulder.

図１〜図８に示すように読書灯１は、灯具１１と、器具本体３１と、弾性材製の押圧部材例えば板ばね４１と、ストッパ５１とを具備している。   As shown in FIGS. 1 to 8, the reading lamp 1 includes a lamp 11, an instrument body 31, a pressing member made of an elastic material such as a leaf spring 41, and a stopper 51.

灯具１１は、カバー１２、灯具ボディ１５、光源２０、レンズ２２等を備えている。   The lamp 11 includes a cover 12, a lamp body 15, a light source 20, a lens 22, and the like.

カバー１２は、灯具１１の正面側部位をなすものであって、合成樹脂製である。図３及び図６等に示すようにカバー１２は、半球状外面１２ａを有し、この外面１２ａの頂部から一体に突出された出射凸部１３を有して、椀形状に形成されている。出射凸部１３の先端は開放されている。出射凸部１３と反対側のカバー１２の端も開放されており、この開放端部において半球状外面１２ａの外径は最大となっている。   The cover 12 forms a front side portion of the lamp 11 and is made of a synthetic resin. As shown in FIGS. 3 and 6 and the like, the cover 12 has a hemispherical outer surface 12a, and has an output convex portion 13 integrally protruding from the top of the outer surface 12a, and is formed in a bowl shape. The tip of the output convex portion 13 is open. The end of the cover 12 opposite to the emission convex portion 13 is also open, and the outer diameter of the hemispherical outer surface 12a is maximum at the open end.

灯具ボディ１５は、灯具１１の背面側部位をなすものであって、金属、好ましくは鉄よりも軽量でかつ熱伝導性も優れるアルミニウム合金のダイキャスト製品である。図３、図６〜図８等に示すように灯具ボディ１５は、ボディ基部１６と、背面凸部１７と、一対の円弧状部１８を備えている。   The lamp body 15 forms a rear side portion of the lamp 11, and is a die-cast product of an aluminum alloy that is lighter than metal, preferably iron, and has excellent thermal conductivity. As shown in FIGS. 3, 6 to 8, and the like, the lamp body 15 includes a body base portion 16, a back convex portion 17, and a pair of arc-shaped portions 18.

ボディ基部１６はカバー１２の内部に配置される部位である。ボディ基部１６をカバー１２内に挿入する時に先頭となる端面、つまり、出射凸部１３側を向いた端面１６ａは平坦面で形成されている。   The body base portion 16 is a portion disposed inside the cover 12. An end surface that becomes the head when the body base portion 16 is inserted into the cover 12, that is, an end surface 16 a facing the emission convex portion 13 side, is formed as a flat surface.

背面凸部１７はボディ基部１６の背面側に一体に突設されている。背面凸部１７の両側面は互いに略平行であり、これら両側面間の背面１７ａは球面の一部で形成されている。背面凸部１７は一対の溝１７ｂを有している。これらの溝１７ｂは、背面凸部１７の頂部からずらして形成され背面１７ａに開放している。   The rear convex portion 17 is integrally projected on the rear side of the body base portion 16. Both side surfaces of the back convex portion 17 are substantially parallel to each other, and the back surface 17a between the both side surfaces is formed as a part of a spherical surface. The back surface convex part 17 has a pair of groove | channels 17b. These grooves 17b are formed so as to be shifted from the top of the rear convex portion 17 and open to the rear surface 17a.

一対の円弧状部１８は、その両端をボディ基部１６の側面に一体に連続させて、ボディ基部１６の側面から直角に張り出すように設けられている。これら円弧状部１８はカバー１２の大径開口端に被さるようになっているとともに、円弧状部１８の中央部外周面に夫々突起１８ａが設けられている。これらの突起１８ａは背面凸部１７から遠ざかるように突出している。図６に示すように灯具ボディ１５は、円弧状部１８とボディ基部１６の側面との間に夫々形成された凹部１５ａを有している。   The pair of arcuate portions 18 are provided so that both ends thereof are integrally connected to the side surface of the body base portion 16 so as to project at right angles from the side surface of the body base portion 16. These arc-shaped portions 18 are configured to cover the large-diameter opening ends of the cover 12, and protrusions 18 a are provided on the outer peripheral surface of the central portion of the arc-shaped portion 18. These protrusions 18 a protrude so as to be away from the rear surface protrusion 17. As shown in FIG. 6, the lamp body 15 has concave portions 15 a formed between the arc-shaped portion 18 and the side surface of the body base portion 16.

以上のように灯具ボディ１５の背面凸部１７の両側面を互いに略平行とし、この背面凸部１７に一対の溝１７ｂを設け、灯具ボディ１５に一対の凹部１５ａを設けた構成は、金属製の灯具ボディ１５を軽くするのに寄与し、結果的に回転操作される部分である灯具１１の軽量化とともに読書灯１全体の軽量化ができる点で好ましい。更に、一対の溝１７ｂ及び一対の凹部１５ａによって灯具ボディ１５の表面積が増やされるので、この灯具ボディ１５からの放熱性能を向上できる点でも好ましい。   As described above, both side surfaces of the rear surface convex portion 17 of the lamp body 15 are substantially parallel to each other, the pair of grooves 17b are provided in the rear surface convex portion 17, and the pair of concave portions 15a is provided in the lamp body 15. This contributes to lightening the lamp body 15 and is consequently preferable in that the reading lamp 1 as a whole can be reduced in weight as well as the lamp 11 which is a part to be rotated. Furthermore, since the surface area of the lamp body 15 is increased by the pair of grooves 17b and the pair of recesses 15a, it is preferable in that the heat dissipation performance from the lamp body 15 can be improved.

灯具ボディ１５とカバー１２とは、図７に示すように互いに嵌合された状態で、溝１７ｂからボディ基部１６を通ってカバー１２にねじ込まれた一対のねじ１９によって連結されている。   As shown in FIG. 7, the lamp body 15 and the cover 12 are connected to each other by a pair of screws 19 screwed into the cover 12 from the groove 17 b through the body base portion 16.

図６及び図７に示すように光源２０には基板２０ａ上に例えば白色発光をするＬＥＤ（発光ダイオード）２０ｂを実装したものが用いられている。光源２０は、ボディ基部１６の端面１６ａ上に熱伝導性シート２１を挟んで配置されている。光源２０を被って配置されるレンズ２２はＬＥＤ２０ｂが発した光を制御して出射するものであって、レンズホルダ２３内に支持されている。レンズホルダ２３は二つ割りのホルダ部材を組み合わせて形成されている。レンズホルダ２３は出射凸部１３内に挿入してカバー１２の内側に配置されている。そして、レンズホルダ２３は、一対の凹部１５ａの内側から夫々挿入されボディ基部１６を通ってレンズホルダ２３のねじ受け部にねじ込まれたねじ２４によって、灯具ボディ１５に取付けられている。   As shown in FIGS. 6 and 7, a light source 20 in which an LED (light emitting diode) 20 b that emits white light, for example, is mounted on a substrate 20 a is used. The light source 20 is disposed on the end surface 16 a of the body base portion 16 with the heat conductive sheet 21 interposed therebetween. The lens 22 disposed to cover the light source 20 controls and emits the light emitted from the LED 20 b and is supported in the lens holder 23. The lens holder 23 is formed by combining two holder members. The lens holder 23 is inserted into the output convex portion 13 and disposed inside the cover 12. The lens holder 23 is attached to the lamp body 15 by screws 24 that are respectively inserted from the inside of the pair of recesses 15 a and are screwed into the screw receiving portions of the lens holder 23 through the body base portion 16.

この取付けにより、レンズホルダ２３とボディ基部１６の端面１６ａとの間に、互いに重なった熱伝導性シート２１と光源２０の基板２０ａとが挟まれて、熱伝導性シート２１がボディ基部１６の端面１６ａに密接されている。これにより、点灯に伴いＬＥＤ２０ｂが発生する熱を、熱伝導性シート２１を経由してボディ基部１６に円滑に伝達して、このボディ基部１６の表面から放出できるので、ＬＥＤ２０ｂの温度上昇が抑制されて所定の発光性能を維持できる。   By this attachment, the heat conductive sheet 21 and the substrate 20a of the light source 20 that are overlapped with each other are sandwiched between the lens holder 23 and the end surface 16a of the body base portion 16, and the heat conductive sheet 21 becomes the end surface of the body base portion 16. 16a. As a result, the heat generated by the LED 20b as it is turned on can be smoothly transferred to the body base 16 via the thermal conductive sheet 21 and released from the surface of the body base 16, so that the temperature rise of the LED 20b is suppressed. The predetermined luminous performance can be maintained.

図１〜図３及び図６中符号２６は絶縁被服された電線を示し、電線２６は一方の凹部１５ａの底を通って光源２０の基板２０ａに設けた図示しない給電用のパターンに接続されている。図３〜図６に示すように電線２６は、背面凸部１７の一側面に沿っており、この部分において背面凸部１７の一側面にねじ止めされた電線ホルダ２７で保持されている。   1 to 3 and 6, reference numeral 26 denotes an insulated wire, and the electric wire 26 is connected to a power supply pattern (not shown) provided on the substrate 20 a of the light source 20 through the bottom of one recess 15 a. Yes. As shown in FIGS. 3 to 6, the electric wire 26 extends along one side surface of the rear surface convex portion 17 and is held by an electric wire holder 27 screwed to one side surface of the rear surface convex portion 17 in this portion.

器具本体３１は、例えばアルミニウム合金のダイキャスト製品であって、図１〜図４等に示すようにリング部３２の背面に一対の円弧状壁３３を突設して形成されている。リング部３２が有した円形の開口３２ａは半球状外面１２ａの最大径より小径であり、この開口３２ａの縁は半球状外面１２ａに接触してこの半球状外面１２ａを摺動可能に支持する弧状面で形成されている。   The instrument body 31 is, for example, an aluminum alloy die-cast product, and is formed by projecting a pair of arc-shaped walls 33 on the back surface of the ring portion 32 as shown in FIGS. The circular opening 32a of the ring portion 32 has a smaller diameter than the maximum diameter of the hemispherical outer surface 12a, and the edge of the opening 32a contacts the hemispherical outer surface 12a to support the hemispherical outer surface 12a slidably. It is formed with a surface.

一対の円弧状壁３３は、それらの間に灯具１１を収容するように相対向して設けられ、その円弧状壁３３の円弧が延びる方向の端間には隙間Ｇ（図３参照）が形成されている。これら一対の隙間Ｇは器具本体３１の周方向に略１８０度離れている。隙間Ｇの幅は灯具ボディ１５の突起１８ａの幅より広い。   The pair of arcuate walls 33 are provided opposite to each other so as to accommodate the lamp 11 therebetween, and a gap G (see FIG. 3) is formed between the ends of the arcuate wall 33 in the direction in which the arc extends. Has been. The pair of gaps G are separated by approximately 180 degrees in the circumferential direction of the instrument body 31. The width of the gap G is wider than the width of the protrusion 18 a of the lamp body 15.

各円弧状壁３３の夫々には、リング部３２と反対側の端部に位置して少なくとも一つのガイド部３４及び部材取付け部として例えばばね取付け孔３５が設けられている。ガイド部３４は、前記反対側の端部の端面に開放しているとともに、この端面から円弧状壁３３の外面にせり出すように傾斜して形成されている。ばね取付け孔３５は、ガイド部３４に対してこれよりリング部３２寄りに隣接して設けられた四角孔で形成されている。   Each arcuate wall 33 is provided with at least one guide portion 34 and, for example, a spring attachment hole 35 as a member attachment portion located at the end opposite to the ring portion 32. The guide portion 34 is open to the end surface of the opposite end portion, and is inclined so as to protrude from the end surface to the outer surface of the arc-shaped wall 33. The spring mounting hole 35 is formed as a square hole provided adjacent to the guide portion 34 and closer to the ring portion 32.

各円弧状壁３３の内面の夫々には、リング部３２と反対側の端部に位置して段部３６が形成されている。これらの段部３６は円弧状壁３３の円弧に沿って延びて形成されている。段部６の途中に凹溝３７がばね取付け孔３５に連続して設けられている。   On each inner surface of each arc-shaped wall 33, a step portion 36 is formed at an end opposite to the ring portion 32. These step portions 36 are formed to extend along the arc of the arc-shaped wall 33. A concave groove 37 is provided in the middle of the step portion 6 so as to be continuous with the spring mounting hole 35.

図１、図３、図４に示すように板ばね４１は、器具本体３１に形成されたばね取付け孔３５と同数の固定部４２と、これら固定部間にわたる押圧部４３とを有している。各固定部４２は、等間隔例えば１２０°毎に配置されていて、いずれもＬ字形状に曲げて形成されている。押圧部４３は三本のアームを放射状に突出させた形状、言い換えれば、三叉形状をなしていて、夫々のアームの先端から固定部４２が折り曲げられている。この板ばね４１は、夫々の固定部４２をばね取付け孔３５に外側から挿入して引掛けることにより器具本体３１に取付けられる。   As shown in FIGS. 1, 3, and 4, the leaf spring 41 has the same number of fixing portions 42 as the spring mounting holes 35 formed in the instrument body 31, and a pressing portion 43 that extends between these fixing portions. Each fixing portion 42 is arranged at equal intervals, for example, every 120 °, and is formed by bending in an L shape. The pressing portion 43 has a shape in which three arms protrude radially, in other words, has a tridental shape, and the fixing portion 42 is bent from the tip of each arm. The leaf spring 41 is attached to the instrument body 31 by inserting the respective fixing portions 42 into the spring attachment holes 35 from the outside and hooking them.

図３等に示すようにストッパ５１は、例えば金属のリングで形成されている。このリング形のストッパ５１の外周の一部には回り止め凸部５２が一体に突設されている。回り止め凸部５２の幅は前記隙間Ｇに嵌合されるようにこの隙間Ｇの幅と略等しく形成されている。ストッパ５１の内周には逃げ溝５３が回り止め凸部５２に隣接するように設けられている。この逃げ溝５３はストッパ５１内を通って引出される前記電線２６との干渉を抑制するために設けられている。図６及び図７に示すようにストッパ５１は段部３６に支持されて器具本体３１の内部に配置される。   As shown in FIG. 3 and the like, the stopper 51 is formed of, for example, a metal ring. An anti-rotation projection 52 is integrally projected on a part of the outer periphery of the ring-shaped stopper 51. The width of the rotation preventing projection 52 is formed to be substantially equal to the width of the gap G so as to be fitted into the gap G. An escape groove 53 is provided on the inner periphery of the stopper 51 so as to be adjacent to the rotation preventing projection 52. The escape groove 53 is provided to suppress interference with the electric wire 26 drawn out through the stopper 51. As shown in FIGS. 6 and 7, the stopper 51 is supported by the step portion 36 and disposed inside the instrument body 31.

次に、器具本体３１、板ばね４１、ストッパ５１、及び予め組立てられた灯具１１を用意して読書灯１を組立てる手順を説明する。   Next, a procedure for assembling the reading lamp 1 by preparing the appliance main body 31, the leaf spring 41, the stopper 51, and the pre-assembled lamp 11 will be described.

まず、器具本体３１の一対の隙間Ｇに灯具１１の一対の突起１８ａを位置合わせし、灯具１１を、そのカバー１２を先頭にして器具本体３１の内側に収容する。これにより、出射凸部１３を含むカバー１２の頂部側部分が器具本体３１の開口３２ａに挿通されて、この開口３２ａの縁に灯具１１の半球状外面１２ａが接して灯具１１が支持される。これとともに、一対の突起１８ａが対応する一対の隙間Ｇ内に配置される。又、この収容状態で灯具１１の背面凸部１７の先端部は器具本体３１の円弧状壁３３より高く突出される。   First, the pair of protrusions 18 a of the lamp 11 are aligned with the pair of gaps G of the instrument body 31, and the lamp 11 is accommodated inside the instrument body 31 with the cover 12 at the top. As a result, the top portion of the cover 12 including the output convex portion 13 is inserted into the opening 32a of the fixture body 31, and the hemispherical outer surface 12a of the lamp 11 is in contact with the edge of the opening 32a to support the lamp 11. At the same time, the pair of protrusions 18a are disposed in the corresponding pair of gaps G. Further, in this accommodated state, the tip of the rear projection 17 of the lamp 11 protrudes higher than the arcuate wall 33 of the fixture body 31.

この後、灯具１１から引き出されている電線２６に対して逃げ溝５３が対向するようにリング形のストッパ５１を器具本体３１内に収容して、この器具本体３１の段部３６にストッパ５１を載せるとともに、このストッパ５１の回り止め凸部５２を一方の隙間Ｇに嵌合させる。これにより、灯具１１の背面凸部１７がストッパ５１に接することなくこの内側に通されるとともに、灯具１１の円弧状部１８が灯具１１の円弧状部１８に対して器具本体３１の中心線が伸びる方向に離れて配置される。この離間距離を図５及び図６に符号Ｌで示す。離間距離Ｌは器具本体３１に対して灯具１１を人間の手で動かすことを許容するために設けられる。   Thereafter, a ring-shaped stopper 51 is accommodated in the instrument body 31 so that the escape groove 53 faces the electric wire 26 drawn out from the lamp 11, and the stopper 51 is placed on the step portion 36 of the instrument body 31. At the same time, the detent protrusion 52 of the stopper 51 is fitted into one gap G. As a result, the rear projection 17 of the lamp 11 passes through the inner side of the lamp 11 without contacting the stopper 51, and the arc-shaped portion 18 of the lamp 11 has a center line of the fixture body 31 with respect to the arc-shaped portion 18 of the lamp 11. It is arranged away in the extending direction. This separation distance is indicated by a symbol L in FIGS. The separation distance L is provided to allow the lamp 11 to be moved by a human hand with respect to the instrument body 31.

最後に、板ばね４１を器具本体３１に取付ける。この取付けは、各固定部４２を夫々器具本体３１のガイド部３４に合わせて板ばね４１を押えることにより行われる。それにより、固定部４２が、弾性変形を伴ってガイド部３４を滑りながら通過した直後に、ばね取付け孔３５に入り込んで引っ掛かる。この場合、図１及び図２に示すように固定部４２を段部３６との間にストッパ５１を挟むように配置する。したがって、板ばね４１の取付けと同時に、この板ばね４１を利用してストッパ５１を器具本体３１から外れないように保持できる。   Finally, the leaf spring 41 is attached to the instrument body 31. This attachment is performed by pressing the leaf spring 41 by aligning each fixing portion 42 with the guide portion 34 of the instrument body 31. Thereby, immediately after the fixing portion 42 passes through the guide portion 34 while being elastically deformed, the fixing portion 42 enters the spring attachment hole 35 and is caught. In this case, as shown in FIGS. 1 and 2, the fixing portion 42 is arranged so as to sandwich the stopper 51 between the step portion 36. Therefore, simultaneously with the attachment of the leaf spring 41, the leaf spring 41 can be used to hold the stopper 51 so as not to be detached from the instrument body 31.

そして、以上の手順での組立てによって、板ばね４１の押圧部４３はある程度弾性変形した状態となって、その中央部４３ａが灯具１１の背面１７ａに弾性的に接するとともに、灯具１１の半球状外面１２ａが開口３２ａの縁に押付けられた状態となって、器具本体３１から外れないように灯具１１が保持される。そのため、器具本体３１の開口３２ａの縁とこれに押付けられた灯具１１の半球状外面１２ａとの間の摩擦力、及び灯具１１の背面１７ａとこれに押付けられて点接触した板ばね４１の押圧部４３との間の摩擦力により、灯具１１が静止状態に保持される。又、図４中二点鎖線で示すように電線２６は押圧部４３の一つのアーム４３ｂを迂回して器具本体３１外に引き出されている。この電線２６の中間部は、押圧部４３に形成したホルダ受け部４４に取付けられる図示しない電線ホルダを介して押圧部４３に保持されるとともに、この保持部と前記電線ホルダ２７とによって、これらの間の電線部分が、灯具１１の動きに拘わらずにアーム４３ｂに接触することがないように形付けられている。   As a result of the assembly according to the above procedure, the pressing portion 43 of the leaf spring 41 is elastically deformed to some extent, and its central portion 43a is elastically in contact with the back surface 17a of the lamp 11 and the hemispherical outer surface of the lamp 11 12a is pressed against the edge of the opening 32a, and the lamp 11 is held so as not to be detached from the instrument body 31. Therefore, the frictional force between the edge of the opening 32a of the fixture body 31 and the hemispherical outer surface 12a of the lamp 11 pressed against the edge, and the pressing of the leaf spring 41 pressed against the back surface 17a of the lamp 11 and point-contacted thereto. The lamp 11 is held stationary by the frictional force with the portion 43. Further, as shown by a two-dot chain line in FIG. 4, the electric wire 26 is drawn out of the instrument body 31 by bypassing one arm 43 b of the pressing portion 43. The intermediate portion of the electric wire 26 is held by the pressing portion 43 via an electric wire holder (not shown) attached to the holder receiving portion 44 formed on the pressing portion 43, and these holding portion and the electric wire holder 27 The intermediate wire portion is shaped so as not to contact the arm 43b regardless of the movement of the lamp 11.

前記構成の読書灯１は、図５中に二点鎖線で示す保護ケース５７に収容されて前記座席の肩部に取付けられる。保護ケース５７は出射凸部１３が通される孔を有している。この孔は灯具１１の傾き調節を妨げない径で形成されている。座席への取付け状態で、保護ケース５７の前面は、座席が有した図示しないクッション材及び表カバーで覆われるが、これらクッション材及び表カバーを通って出射凸部１３が突出されている。これにより、出射凸部１３を摘んで灯具１１を傾けるなど灯具１１の向きを調節できるので、出射凸部１３がない構成に比較して調節操作が容易で僅かな動きでも正確に操作することができる。この場合、灯具１１を押してその半球状外面１２ａが開口３２ａより離れるように操作すると、灯具１１の動きに対する抵抗が減るので、灯具１１の向きの調節をより容易にできる。   The reading lamp 1 having the above configuration is accommodated in a protective case 57 indicated by a two-dot chain line in FIG. 5 and attached to the shoulder portion of the seat. The protective case 57 has a hole through which the output convex portion 13 passes. This hole is formed with a diameter that does not interfere with the tilt adjustment of the lamp 11. In the state of being attached to the seat, the front surface of the protective case 57 is covered with a cushion material and a front cover (not shown) of the seat, and the output convex portion 13 protrudes through the cushion material and the front cover. As a result, the direction of the lamp 11 can be adjusted, for example, by tilting the lamp 11 while holding the exit convex portion 13. Therefore, the adjustment operation is easier and accurate even with a slight movement compared to a configuration without the exit convex portion 13. it can. In this case, if the lamp 11 is pushed and operated so that the hemispherical outer surface 12a is separated from the opening 32a, the resistance to the movement of the lamp 11 is reduced, so that the direction of the lamp 11 can be adjusted more easily.

こうして灯具１１からの光の照射方向を変える調節をするには、前記摩擦力に勝る操作力を灯具１１に与えて、この灯具１１を回転操作することで実現される。その際、灯具１１の半球状外面１２ａは器具本体３１の開口３２ａの縁を滑り動き、かつ、灯具１１の背面１７ａは板ばね４１の中央部４３ａを滑り動く。そのため、灯具１１が所望の向きに調節された時点で出射凸部１３から手を離すことにより、そのときの位置に灯具１１を静止させることができる。なお、器具本体３１の隙間Ｇの幅は灯具１１の突起１８ａより十分に大きいので、前記調節において突起１８ａは隙間Ｇ内を遊び動くとともに、突起１８ａが円弧状壁３３に当たる場合には灯具１１の最大傾き角度が規制される。   In this way, adjustment to change the irradiation direction of the light from the lamp 11 is realized by applying an operation force that exceeds the frictional force to the lamp 11 and rotating the lamp 11. At that time, the hemispherical outer surface 12a of the lamp 11 slides on the edge of the opening 32a of the fixture body 31, and the back surface 17a of the lamp 11 slides on the central portion 43a of the leaf spring 41. Therefore, when the lamp 11 is adjusted to a desired direction, the lamp 11 can be stopped at the position at that time by releasing the hand from the emission convex portion 13. In addition, since the width of the gap G of the fixture body 31 is sufficiently larger than the protrusion 18a of the lamp 11, the protrusion 18a freely moves in the gap G in the adjustment, and when the protrusion 18a hits the arcuate wall 33, the lamp 11 The maximum tilt angle is regulated.

以上の調節操作の際に灯具１１が過大な力で押込まれることが考えられる。この他、前記通路を通る乗客が誤って読書灯１を手で突いた場合に灯具１１は過大な力で押込まれる。この場合、灯具１１が最大で前記離間距離Ｌの分だけ押込まれ、それに伴い背面凸部１７が板ばね４１の押圧部４３を押して、この押圧部４３を弾性変形させる。   It is conceivable that the lamp 11 is pushed with an excessive force during the adjustment operation described above. In addition, when a passenger passing through the passage accidentally pokes the reading lamp 1 by hand, the lamp 11 is pushed with an excessive force. In this case, the lamp 11 is pushed in by the maximum distance L, and the back convex portion 17 pushes the pressing portion 43 of the leaf spring 41 and elastically deforms the pressing portion 43 accordingly.

しかし、ある程度前記押込みが進行すると、灯具１１の円弧状部１８が器具本体３１に取付けられたストッパ５１に当たる。このストッパ５１は、複数個所のばね取付け孔３５に引っ掛かって器具本体３１に支持されている板ばね４１の固定部４２で支持されている。したがって、ストッパ５１を介して板ばね４１で灯具１１が受止められて、それ以上の灯具１１の押込みが妨げられる。つまり、前記離間距離Ｌを越えて灯具１１が過度に押込まれないようにできる。これにより、灯具１１を器具本体３１の開口３２ａに向けて付勢している板ばね４１の押圧部４３に過大な押込み荷重の全てが作用することがなくなる。そして、ストッパ５１により灯具１１の押込みが制限された時、板ばね４１の押圧部４３の変形は未だ弾性限界内にあるので、板ばね４１の永久変形が防止される。そして、前記過大な押込み力が消失すると同時に、板ばね４１の押圧部４３の弾性復帰により灯具１１が押戻される。従って、板ばね４１のばね力による前記摩擦力が所定値に保持されるので、灯具１１を調節した向きに保持する性能が低下しないようにでき、それに伴い灯具１１の照射方向を確実に保持できる。   However, when the push-in progresses to some extent, the arc-shaped portion 18 of the lamp 11 hits the stopper 51 attached to the fixture body 31. The stopper 51 is supported by a fixing portion 42 of a leaf spring 41 that is hooked by a plurality of spring mounting holes 35 and supported by the instrument body 31. Accordingly, the lamp 11 is received by the leaf spring 41 via the stopper 51, and further pushing of the lamp 11 is prevented. That is, the lamp 11 can be prevented from being pushed excessively beyond the separation distance L. As a result, all of the excessive pressing load does not act on the pressing portion 43 of the leaf spring 41 that urges the lamp 11 toward the opening 32 a of the instrument body 31. When the pushing of the lamp 11 is restricted by the stopper 51, the deformation of the pressing portion 43 of the leaf spring 41 is still within the elastic limit, so that the permanent deformation of the leaf spring 41 is prevented. And the lamp 11 is pushed back by the elastic return of the press part 43 of the leaf | plate spring 41 at the same time the said excessive pushing force lose | disappears. Accordingly, since the frictional force generated by the spring force of the leaf spring 41 is held at a predetermined value, the performance of holding the lamp 11 in the adjusted direction can be prevented from being lowered, and accordingly the irradiation direction of the lamp 11 can be reliably held. .

更に、ストッパ５１はリングであるから、過度に灯具１１が押込まれる際に、この灯具１１の向きがどうであっても、言い換えれば、灯具１１が過度に押し込まれる方向がいかなる方向であっても、板ばね４１を介して器具本体３１に支持されているストッパ５１で、押込まれた灯具１１を確実に受止めることができる。このことは、灯具１１を押込むようにしながらこの灯具１１の向きを調節する場合でも同様であり、この場合、ストッパ５１での位置規制により、向きが変えられつつある灯具１１の回転の中心となる位置が大きく変わることを制限できるので、灯具１１の向きの調節が容易である。   Further, since the stopper 51 is a ring, when the lamp 11 is excessively pushed, regardless of the direction of the lamp 11, in other words, the direction in which the lamp 11 is excessively pushed is any direction. However, the pressed lamp 11 can be reliably received by the stopper 51 supported by the instrument body 31 via the leaf spring 41. The same applies to the case where the direction of the lamp 11 is adjusted while the lamp 11 is pushed in. In this case, the center of rotation of the lamp 11 whose direction is being changed due to the position restriction by the stopper 51. Since it is possible to limit the change of the position, the direction of the lamp 11 can be easily adjusted.

又、以上の受止めに伴い、或いは灯具１１の向きの調節において、ストッパ５１にその周方向に沿う移動力が作用することがあるが、回り止め凸部５２が隙間Ｇに嵌合しているので、リング形のストッパ５１が回転されることがない。そのため、電線２６が板ばね４１の縁に接して傷付けられないようにできる。そして、以上の回り止めの構成は、回り止め部品を格別に要しない点で好ましい。   In addition, a movement force along the circumferential direction may act on the stopper 51 along with the above-described reception or in adjusting the direction of the lamp 11, but the detent projection 52 is fitted in the gap G. Therefore, the ring-shaped stopper 51 is not rotated. Therefore, it is possible to prevent the electric wire 26 from being damaged by being in contact with the edge of the leaf spring 41. The anti-rotation configuration described above is preferable in that no anti-rotation component is required.

しかも、ストッパ５１を器具本体３１に取付けるのに、器具本体３１に取付けられた板ばね４１の複数の固定部４２を利用して、これらと器具本体３１に設けた段部３６との間にストッパ５１を挟んで実現したので、格別な部品を要しない点で好ましい。   Moreover, in order to attach the stopper 51 to the instrument main body 31, a plurality of fixing portions 42 of the leaf spring 41 attached to the instrument main body 31 are used, and a stopper is provided between these and the step portion 36 provided on the instrument main body 31. Since it is realized with 51 in between, it is preferable in that no special parts are required.
