図１及び図２に示す照明器具１は、壁や天井等の被設置部５０に形成された埋込孔５１等の開口に挿入されてスポットライト等として利用される埋め込み式の照明器具であり、球状の灯具１０と、灯具１０の下方を支持する枠状の器具本体２０と、灯具１０を上方から押圧する押圧部材の一例としての押さえばね３０と、器具本体２０に固定された取付部材の一例として埋込孔５１を内側から付勢する取付ばね４０とを備えている。 A first embodiment of the present invention will be described below with reference to FIGS. For the sake of explanation, the configuration is appropriately omitted in each drawing.
The luminaire 1 shown in FIGS. 1 and 2 is an embedded luminaire that is used as a spotlight or the like by being inserted into an opening such as an embedding hole 51 formed in an installation part 50 such as a wall or a ceiling. A spherical lamp 10, a frame-shaped instrument body 20 that supports the lower part of the lamp 10, a pressing spring 30 as an example of a pressing member that presses the lamp 10 from above, and an attachment member fixed to the instrument body 20. As an example, an attachment spring 40 that urges the embedded hole 51 from the inside is provided.

灯具１０は、器具本体２０と押さえばね３０とによって、回転可能な状態で、挟持されている。図３に示されるように、灯具１０は、それぞれ金属、好ましくはアルミニウム合金等から半球状に形成された本体部１１及びカバー部１２がねじ等の固定部材１３によって結合され、球状に構成されている。灯具１０の内部には、発光源としてのＬＥＤ１４等が収容されている。   The lamp 10 is sandwiched between the fixture body 20 and the pressing spring 30 in a rotatable state. As shown in FIG. 3, the lamp 10 includes a main body portion 11 and a cover portion 12 each formed in a hemispherical shape from a metal, preferably an aluminum alloy, etc., and is connected to a fixing member 13 such as a screw to form a spherical shape. Yes. Inside the lamp 10, an LED 14 as a light source is accommodated.

本体部１１の外周面は凸状背面部１１ａを有する。この凸状背面部１１ａは球面の一部からなり、言い換えれば、凸曲面をなしている。本体１１の外周面には、放熱部１７や、後述する回転規制凹部２４に対応する２つの回転規制凸部１８が形成されている。   The outer peripheral surface of the main body portion 11 has a convex back surface portion 11a. This convex back surface portion 11a is composed of a part of a spherical surface, in other words, a convex curved surface. On the outer peripheral surface of the main body 11, a heat radiating portion 17 and two rotation restricting convex portions 18 corresponding to a rotation restricting concave portion 24 described later are formed.

器具本体２０は、合成樹脂等からなり、灯具１０の下方外周を囲む円筒部２１と埋込孔５１の縁に当接する外鍔部２２とが一体となって、枠状に形成されている。外鍔部２２の外径は埋込孔５１の径より大きく、また、灯具１０が載置される受け部の一例としての開口部２３の縁２１ａは灯具１０の外径より小さく構成されている。開口部２３の縁２１ａから外鍔部２２の下端に向けて内径が広くなるようにテーパ状に形成されている。
円筒部２１において、対向する二箇所に所定の幅及び深さを有する回転規制凹部２４が形成されている。この回転規制凹部２４の内壁に上記灯具１０の回転規制凸部１８が当接することで灯具１０の回転角度や回転方向が規制される。
また、円筒部２１の外周面において、対向する二箇所に、接線方向と平行に形成された平面部２５が形成されている。この平面部２５において、取付ばね４０及び押さえばね３０が器具本体２０に取り付けられる。平面部２５の中心には、係合爪２６が形成されている。この係合爪２６は器具本体２０の外周面から外方向に突出した爪本体２６ａとこの爪本体２６ａの外側から下方に突出した先端部２６ｂとを備え、この先端部２６ｂに後述する係合孔３３、４４が係合することにより押さえばね３０及び取付ばね４０固定される。さらに、平面部２５の一方の端部には取付ばね４０の端部が挿入される溝２７が形成されている。 The fixture body 20 is made of a synthetic resin or the like, and a cylindrical portion 21 that surrounds the lower outer periphery of the lamp 10 and an outer flange portion 22 that comes into contact with the edge of the embedded hole 51 are integrally formed in a frame shape. The outer diameter of the outer casing portion 22 is larger than the diameter of the embedded hole 51, and the edge 21 a of the opening 23 as an example of a receiving portion on which the lamp 10 is placed is configured to be smaller than the outer diameter of the lamp 10. . It is formed in a tapered shape so that the inner diameter becomes wider from the edge 21 a of the opening 23 toward the lower end of the outer flange 22.
In the cylindrical portion 21, rotation restricting concave portions 24 having a predetermined width and depth are formed at two opposing positions. When the rotation restricting convex portion 18 of the lamp 10 abuts against the inner wall of the rotation restricting concave portion 24, the rotation angle and direction of the lamp 10 are restricted.
Further, on the outer peripheral surface of the cylindrical portion 21, flat portions 25 formed in parallel to the tangential direction are formed at two opposing positions. In the flat portion 25, the attachment spring 40 and the holding spring 30 are attached to the instrument body 20. An engaging claw 26 is formed at the center of the flat portion 25. The engaging claw 26 includes a claw body 26a that protrudes outward from the outer peripheral surface of the instrument body 20, and a tip portion 26b that protrudes downward from the outside of the claw body 26a. The presser spring 30 and the mounting spring 40 are fixed by the engagement of 33 and 44. Further, a groove 27 into which the end of the attachment spring 40 is inserted is formed at one end of the flat portion 25.

図６（ａ）〜（ｃ）に示す押さえばね３０は、板厚方向に弾性変形可能な金属等のばね板からなり、灯具１０の凸状背面部１１aに弾性的に当接（弾接）して器具本体２０に向けて押圧する押圧部３１と、取付ばね４０の取付部４１を外側から覆うように器具本体２０に取り付けられる両側部３２とが一体となってコ字状に形成されている。両側部３２の下端には、係合爪２６に係合される係合孔３３が形成されている。なお、押さえばね３０は自由状態においては両側部３２の係合孔３３の下端から押圧部３１までの長さは器具本体２０の係合爪２６の基端部の下端から載置された灯具１０の上端までの長さより小さく構成されている。したがって、図１に示すように押さえばね３０を灯具１０の凸状背面部１１ａを覆うように器具本体２０に取り付けた状態では、押圧部３１が、曲げ変形する。とともに灯具１０を器具本体２０に向けて押圧付勢する。更に、押さえばね３０が上方に動かされてその両側部３２が係合爪２６に引っ掛かるので、両側部３２が係合爪２６から側方に外れないように保持される。
また、係合孔３３は、両側部３２が係合爪２６を中心として回転できるように、係合爪２６の基端よりも数ミリ程度大きく形成され、嵌合隙間３３ａを有している。この嵌合隙間３３ａによって、図１１に示すように、灯具１０が自らの中心Ｇの回りを回転すると、両側部３２が僅かに（α）回転するとともに押圧部３１が追従して動くため回転の初動動作がスムーズに行われる。このとき、両側部３２の内側において係合爪２６に取り付けられている取付ばね４０は押さえばね３０と別体に構成されているとともに係合孔４４は嵌合隙間を有さないため傾くことがない。 The holding spring 30 shown in FIGS. 6A to 6C is made of a spring plate made of metal or the like that can be elastically deformed in the plate thickness direction, and elastically abuts (elastic contact) with the convex back surface portion 11a of the lamp 10. Then, the pressing part 31 that presses toward the instrument main body 20 and the both side parts 32 that are attached to the instrument main body 20 so as to cover the attachment part 41 of the attachment spring 40 from the outside are integrally formed in a U-shape. Yes. An engagement hole 33 that is engaged with the engagement claw 26 is formed at the lower ends of the side portions 32. In the free state, the length of the holding spring 30 from the lower end of the engaging hole 33 of the both side portions 32 to the pressing portion 31 is set from the lower end of the base end portion of the engaging claw 26 of the instrument body 20. It is comprised smaller than the length to the upper end of. Therefore, in the state where the pressing spring 30 is attached to the fixture main body 20 so as to cover the convex back surface portion 11a of the lamp 10, as shown in FIG. At the same time, the lamp 10 is pressed and urged toward the instrument body 20. Further, since the holding spring 30 is moved upward and both side portions 32 thereof are caught by the engaging claws 26, the both side portions 32 are held so as not to be detached from the engaging claws 26 to the side.
Further, the engagement hole 33 is formed to be several millimeters larger than the base end of the engagement claw 26 so that the both side portions 32 can rotate around the engagement claw 26, and has a fitting gap 33a. When the lamp 10 rotates around its own center G as shown in FIG. 11 due to the fitting gap 33a, both side portions 32 rotate slightly (α) and the pressing portion 31 follows and moves. Initial movement is performed smoothly. At this time, the attachment spring 40 attached to the engagement claw 26 inside the both side portions 32 is configured separately from the presser spring 30 and the engagement hole 44 does not have a fitting gap, so that it can tilt. Absent.

図７（ａ）及び（ｂ）に示される取付ばね４０は複数、例えば２枚用いられ、板厚方向に弾性変形可能な金属等のばね板からなり、器具本体２０の平面部２５に取り付けられる取付部４１と、挿入時に埋込孔５１の内周を付勢する付勢部４２とが一体に形成されている。また、付勢部４２の基端、すなわち取付部４１と付勢部４２の接続部分は、弾性変形しやすくするためのスリット４３ａが形成され、曲げ変形許容部４３を構成している。取付部４１は矩形状を成し、中心に係合孔４４を備えている。取付部４１の端部が器具本体２０の溝２７に挿入された状態で、係合孔４４が前記係合爪２６に係合することにより取付ばね４０が器具本体２０に固定されている。また、この取付部４１は押さえばね３０の両側部３２で覆われる。   A plurality of, for example, two attachment springs 40 shown in FIGS. 7A and 7B are used. The attachment springs 40 are made of a metal spring plate that can be elastically deformed in the plate thickness direction and attached to the flat portion 25 of the instrument body 20. The mounting portion 41 and a biasing portion 42 that biases the inner periphery of the embedding hole 51 at the time of insertion are integrally formed. Further, the base end of the urging portion 42, that is, the connecting portion between the mounting portion 41 and the urging portion 42 is formed with a slit 43 a for facilitating elastic deformation, and constitutes a bending deformation allowing portion 43. The attachment portion 41 has a rectangular shape and includes an engagement hole 44 at the center. The attachment spring 40 is fixed to the instrument body 20 by engaging the engagement holes 44 with the engagement claws 26 in a state where the end of the attachment part 41 is inserted into the groove 27 of the instrument body 20. Further, the attachment portion 41 is covered with both side portions 32 of the presser spring 30.

図２に示すように、付勢部４２は、自由状態においては器具本体２０の接線方向に直線状に延び、器具本体２０の外方に張り出している。このとき２枚の付勢部４２の先端４２ａ間の距離は、埋込孔５１の径より大きく形成されている。この付勢部４２は内径方向、すなわち、付勢部４２の先端４２ａが器具本体２０の外周面に沿うように弾性変形可能である。また、２枚の取付ばね４０は、その取付部４１が回転規制凹部２４及び回転規制凸部１８の位置と異なるようにずらされているとともに、その付勢部４２は係合爪２６を中心として回転規制凹部２４及び回転規制凸部１８と反対方向に延びるように配置されている。すなわち、取付ばね４０が自由状態であっても弾性変形した際にもこれら回転規制凹部２４及び回転規制凸部１８に干渉しないようになっている。
さらに、付勢部４２の端部は斜めに形成されて斜辺４２ｂを構成している。この斜辺４２ｂは、埋込孔５１の内周面の上端５２に当接することにより、埋込孔５１の内周面を外側に付勢するとともに、照明器具１の落下を防止する機能を備える。 As shown in FIG. 2, the urging portion 42 extends linearly in the tangential direction of the instrument main body 20 in a free state, and projects outward from the instrument main body 20. At this time, the distance between the tips 42 a of the two urging portions 42 is formed larger than the diameter of the embedded hole 51. The urging portion 42 can be elastically deformed in the inner diameter direction, that is, the tip 42 a of the urging portion 42 is along the outer peripheral surface of the instrument body 20. Further, the two attachment springs 40 are shifted so that their attachment portions 41 are different from the positions of the rotation restricting concave portion 24 and the rotation restricting convex portion 18, and their biasing portions 42 are centered on the engaging claws 26. It arrange | positions so that the rotation control recessed part 24 and the rotation control convex part 18 may extend in the opposite direction. That is, even when the mounting spring 40 is in a free state, it does not interfere with the rotation restricting recess 24 and the rotation restricting convex 18 even when elastically deforming.
Further, the end portion of the urging portion 42 is formed obliquely to form a hypotenuse 42b. The oblique side 42b has a function of urging the inner peripheral surface of the embedded hole 51 outward by abutting against the upper end 52 of the inner peripheral surface of the embedded hole 51 and preventing the lighting fixture 1 from falling.

照明器具１を組み立てる手順について説明する。まず、２枚の取付ばね４０を２箇所の平面部２５にそれぞれ取り付ける。このとき、取付部の端部４１ａを溝２７に挿し込むとともに器具本体２０の係合爪２６に係合させる。ついで、灯具１０を器具本体２０の円筒部２１の内側に配置する。このとき、灯具１０の照射方向を下方に向け、開口部２３の縁２１ａに当具１０のカバー部１２の半球状外面を摺動可能に接触させて、この縁２１ａに灯具１０を変向可能に支持させる。なお、取付ばね４０を取り付ける前に灯具１０を載置してもよい。ついで、灯具１０の上方から凸状背面部１１ａを覆うように押さえばね３０を器具本体２０に取り付ける。このとき、押圧部３１を凸状背面部１１ａに当接させるとともに平面部２５に既に取り付けられている取付ばね４０の取付部４１を外側から覆うように係合孔３３に係合爪２６を引っ掛ける。こうして照明器具１が組み立てられる。   A procedure for assembling the lighting fixture 1 will be described. First, the two attachment springs 40 are attached to the two flat portions 25, respectively. At this time, the end portion 41 a of the attachment portion is inserted into the groove 27 and engaged with the engagement claw 26 of the instrument body 20. Next, the lamp 10 is disposed inside the cylindrical portion 21 of the instrument body 20. At this time, the irradiation direction of the lamp 10 is directed downward, the hemispherical outer surface of the cover portion 12 of the tool 10 is slidably brought into contact with the edge 21a of the opening 23, and the lamp 10 can be turned to the edge 21a. To support. Note that the lamp 10 may be placed before the attachment spring 40 is attached. Next, the holding spring 30 is attached to the fixture body 20 so as to cover the convex back surface portion 11a from above the lamp 10. At this time, the engaging claw 26 is hooked on the engaging hole 33 so that the pressing portion 31 is brought into contact with the convex back surface portion 11a and the attaching portion 41 of the attaching spring 40 already attached to the flat portion 25 is covered from the outside. . Thus, the lighting fixture 1 is assembled.

以上のように構成された照明器具１を埋込孔５１に取り付ける手順を説明する。まず図９に示すように、取付ばね４０の付勢部４２を内径方向に弾性変形させ、付勢部４２を、器具本体２０の外周面に沿うように曲げることにより、２枚の付勢部４２の先端４２ａを互いに近づける。このとき、スリット４３ａが形成されていることにより容易に変形可能であるとともに溝２７に掛かる負担が軽減される。ついで、変形により付勢部４２の先端４２ａ同士の距離を埋込孔５１の径より小さくした状態で埋込孔５１に挿入する。挿入後、変形させる力を解除すると、付勢部４２が弾性復元力により接線方向に広がる。このとき、図８に示すように２枚の取付ばね４０の付勢部４２の先端４２ａ同士が離間し、斜辺４２ｂが埋込孔５１の内周面の上端５２に当接する。こうして、付勢部４２の斜辺４２ｂにより埋込孔５１の内周面の上端５２を外方向に付勢するとともに、斜辺４２ｂが埋込孔５１の内周面の上端５２に支持されることにより照明器具１が埋込孔５１に固定される。   The procedure for attaching the lighting fixture 1 configured as described above to the embedding hole 51 will be described. First, as shown in FIG. 9, two biasing portions are formed by elastically deforming the biasing portion 42 of the mounting spring 40 in the inner diameter direction and bending the biasing portion 42 along the outer peripheral surface of the instrument body 20. The tips 42a of 42 are brought close to each other. At this time, since the slit 43a is formed, the slit 43a can be easily deformed, and the burden on the groove 27 is reduced. Subsequently, it inserts in the embedding hole 51 in the state which made the distance of the front-end | tips 42a of the urging | biasing part 42 smaller than the diameter of the embedding hole 51 by deformation | transformation. When the force for deforming is released after the insertion, the urging portion 42 spreads in the tangential direction by the elastic restoring force. At this time, as shown in FIG. 8, the tips 42 a of the urging portions 42 of the two mounting springs 40 are separated from each other, and the hypotenuse 42 b abuts against the upper end 52 of the inner peripheral surface of the embedded hole 51. Thus, the oblique side 42b of the urging portion 42 urges the upper end 52 of the inner peripheral surface of the embedded hole 51 outward, and the inclined side 42b is supported by the upper end 52 of the inner peripheral surface of the embedded hole 51. The lighting fixture 1 is fixed to the embedding hole 51.

この照明器具１の照射方向を変更する際は、図１０に示すように器具本体２０の開口部２３から露出した灯具１０のカバー部１２を押圧することにより任意の方向に灯具１０を回転させる。このとき、図１１に示すように、回転規制凸部１８と回転規制凹部２４により、回転角度が一定に制限される。すなわち、回転規制凸部の側壁１８ａが回転規制凹部の内側壁２４ａに当接することにより器具本体２０の外周方向の回転角度が制限されるとともに、回転規制凸部１８の下面１８ｂが回転規制凹部２４の底面２４ｂに当接することにより図１１に示す角度（β）に制限される。   When changing the irradiation direction of the lighting fixture 1, the lamp 10 is rotated in an arbitrary direction by pressing the cover portion 12 of the lighting fixture 10 exposed from the opening 23 of the fixture body 20 as shown in FIG. 10. At this time, as shown in FIG. 11, the rotation angle is restricted to be constant by the rotation restricting protrusion 18 and the rotation restricting recess 24. That is, the rotation angle in the outer circumferential direction of the instrument body 20 is restricted by the side wall 18a of the rotation restricting convex portion coming into contact with the inner wall 24a of the rotation restricting concave portion, and the lower surface 18b of the rotation restricting convex portion 18 is the rotation restricting concave portion 24. 11 is limited to the angle (β) shown in FIG.

上記照明器具１において、取付ばね４０と押さえばね３０とは別体に構成され、かつ押さえばね３０は器具本体２０に回転可能に係合しているため、互いに影響することがなく、取付ばね４０の付勢力を維持しつつ灯具１０の回転をスムーズに行うことができる。   In the lighting apparatus 1, the mounting spring 40 and the pressing spring 30 are configured separately, and the pressing spring 30 is rotatably engaged with the apparatus main body 20. The lamp 10 can be smoothly rotated while maintaining the urging force.

また、一つの係合爪２６に取付ばね４０の係合孔４４と押さえばね３０の係合孔４４を両方取り付けるため組み立て性が良い。これに加え、器具本体２０外周に形成された溝２７に取付ばね４０の端部が支持されるため、取付ばね４０の弾性変形による力が押さえばね３０に影響して、この押さえばね３０を変形させることがない。これにより、押圧部３１と灯具１０との摩擦力が大きく変化することがなく、灯具１０が回転させ難くなること、及び回転し易くなり過ぎることがないから、器具本体２０の取付け状態に拘わらず灯具１０を安定して回転させることができる。さらに、取付ばね４０にスリット４３ａを形成したことにより、溝２７にかかる力を軽減することができる。   Further, since both the engagement hole 44 of the attachment spring 40 and the engagement hole 44 of the holding spring 30 are attached to one engagement claw 26, the assemblability is good. In addition, since the end portion of the attachment spring 40 is supported by the groove 27 formed on the outer periphery of the instrument body 20, the force due to the elastic deformation of the attachment spring 40 affects the pressure spring 30 and deforms the pressure spring 30. I will not let you. Accordingly, the frictional force between the pressing portion 31 and the lamp 10 does not change greatly, and the lamp 10 is not easily rotated and is not easily rotated. Therefore, regardless of the mounting state of the instrument body 20. The lamp 10 can be rotated stably. Furthermore, by forming the slit 43a in the attachment spring 40, the force applied to the groove 27 can be reduced.

回転規制凹部２４及び回転規制凸部１８と取り付けばね４０の位置が異なるため、取付ばね４０が弾性変形した際にも回転規制凹部２４及び回転規制凸部１８に干渉することがなく、灯具１０の回転が取付ばね４０に邪魔されない。   Since the positions of the rotation restricting concave portion 24 and the rotation restricting convex portion 18 and the attachment spring 40 are different, even when the attachment spring 40 is elastically deformed, the rotation restricting concave portion 24 and the rotation restricting convex portion 18 are not interfered with each other. The rotation is not disturbed by the mounting spring 40.

灯具１０がアルミニウム等合金で形成され、かつ、器具本体２０の背面に突出した凸状背面部１１ａに金属製の押さえばね３０がそのばね力で密に当接することによりこれら両部材から外方への放熱性が良い。したがって、ＬＥＤ１４の寿命低下を抑制できる。   The lamp 10 is made of an alloy such as aluminum, and the metal pressing spring 30 is in close contact with the convex back surface portion 11a protruding from the back surface of the instrument body 20 by the spring force, so that the two members move outward. Good heat dissipation. Therefore, the lifetime reduction of LED14 can be suppressed.

係合爪２６及び係合孔４４により、ねじやリベットを使用することなく取付ばね４０を器具本体２０に取り付けることが可能であるため器具本体２０の開口径を小型にすることができる。   With the engagement claw 26 and the engagement hole 44, the attachment spring 40 can be attached to the instrument main body 20 without using screws or rivets, so that the opening diameter of the instrument main body 20 can be reduced.

さらに、付勢部４２の斜辺４２ｂが、埋込孔５１を外方向に付勢すると同時に上下方向において支持されるため、落下防止の部材が不要であり、また、多様な径、厚さの被設置部の開口に適用することができる。   Further, since the oblique side 42b of the urging portion 42 urges the embedded hole 51 in the outward direction and is supported in the up-and-down direction, a member for preventing the fall is unnecessary, and the cover with various diameters and thicknesses is not required. It can be applied to the opening of the installation part.
