(FIG. 12 described later).

（バネ部１３０の個数）
バネ部１３０は、本体部１００の長手方向を二等分する中心軸１１７（図３）の左右に、各一個設けられる。各バネ部１３０は、固定部である第１平坦部Ｌ１が中心軸１１７を向き、屈曲部Ｋが蓋部１１５方向へ向くように配置される。よって、バネ部１３０は、外側方向（図１１の（ａ））へ開くように可動する。 (Number of spring portions 130)
One spring part 130 is provided on each of the left and right sides of the central axis 117 (FIG. 3) that bisects the longitudinal direction of the main body part 100. Each spring part 130 is arranged such that the first flat part L1 as a fixing part faces the central axis 117 and the bent part K faces the lid part 115 direction. Therefore, the spring part 130 is movable so as to open in the outward direction ((a) in FIG. 11).

（光源部２００の装着作業）
次に、図１１を用いて、天井に取り付けられた本体部１００（バネ部１３０）に、作業者が光源部２００（連結金具２５０）を取り付ける作業を説明する。
図１１において、
（ａ）は、本体部１００に光源部２００が取り付けられる前の状態を示す。
（ｂ）は、作業者がバネ部１３０の円弧部Ｅの曲率が大きくなるように、バネ部１３０を弾性変形させた状態で光源部２００の連結金具２５０に屈曲部Ｋを連結した状態を示す。（ｃ）は、円弧部Ｅの裏側が連結金具２５０の開口縁部２５０ａ−１−１に対して摺動する状態を示す。
（ｄ）は、本体部１００に光源部２００が取り付けられた状態を示す。 (Installation work of the light source unit 200)
Next, an operation in which an operator attaches the light source unit 200 (connecting bracket 250) to the main body unit 100 (spring unit 130) attached to the ceiling will be described with reference to FIG.
In FIG.
(A) shows the state before the light source part 200 is attached to the main-body part 100. FIG.
(B) shows the state in which the bent portion K is connected to the connecting fitting 250 of the light source unit 200 in a state where the operator elastically deforms the spring portion 130 so that the curvature of the arc portion E of the spring portion 130 is increased. . (C) shows the state in which the back side of the circular arc part E slides with respect to the opening edge part 250a-1-1 of the connection metal fitting 250. FIG.
(D) shows a state in which the light source unit 200 is attached to the main body unit 100.

（図１１の（ａ））
図１１の（ａ）において、本体部１００では取付部１１２にバネ部１３０の第１平坦部Ｌ１が当接してネジ１１６により固定されている（図５に同じ）。光源部２００は本体部１００に取り付けられていない状態である。 ((A) in FIG. 11)
11A, in the main body portion 100, the first flat portion L1 of the spring portion 130 abuts on the attachment portion 112 and is fixed by a screw 116 (same as in FIG. 5). The light source unit 200 is not attached to the main body unit 100.

（図１１の（ｂ））
次に、図１１の（ｂ）において、バネ部１３０は、第２平坦部Ｌ２（可動軸）を回転の中心として、円弧部Ｅ（摺動部）が取付部１１２に対して垂直状態になるように弾性変形した状態である。作業者は、両方の連結金具２５０について、バネ挿入孔２５０ａ−１にバネ部１３０の屈曲部Ｋからバネ部１３０をくぐらせる。作業者は、バネ部１３０の屈曲部Ｋを、連結金具２５０のバネ挿入孔２５０ａ−１（図９）の開口縁部２５０ａ−１−１に引っ掛けて、光源部２００を本体部１００に吊り下げる。バネ部１３０は図３のように、２個のバネ部１３０が、本体部１００の両端部分に配置されており、図１８のように光源部２００は２個のバネ部１３０で本体部１００に対して略平行な状態で保持することができる。照明器具１０００の施工時のときであれば、作業者は図１８の状態で、両手あるいは片手で光源部２００を支持する必要なく、コネクタの接続作業などができる。 ((B) of FIG. 11)
Next, in FIG. 11B, the spring portion 130 has a circular arc portion E (sliding portion) perpendicular to the mounting portion 112 with the second flat portion L <b> 2 (movable shaft) as the center of rotation. The state is elastically deformed. The operator causes the spring part 130 to pass through the spring insertion hole 250a-1 from the bent part K of the spring part 130 with respect to both of the connection fittings 250. The operator hooks the bent portion K of the spring portion 130 on the opening edge portion 250 a-1-1 of the spring insertion hole 250 a-1 (FIG. 9) of the connection fitting 250 and suspends the light source unit 200 from the main body portion 100. . As shown in FIG. 3, two spring portions 130 are arranged at both end portions of the main body portion 100 as shown in FIG. 3, and the light source portion 200 is connected to the main body portion 100 by two spring portions 130 as shown in FIG. It can be held in a substantially parallel state. At the time of construction of the lighting fixture 1000, the operator can connect the connector without having to support the light source unit 200 with both hands or one hand in the state shown in FIG.

（図１１の（ｃ））
次に、図１１の（ｃ）において、作業者が光源部２００を上方（天井方向）に持ち上げると、バネ部１３０の円弧部Ｅの裏面が、バネ挿入孔２５０ａ−１の開口縁部２５０ａ−１−１に対して、バネの復元力により摺動する。このバネ部１３０（円弧部Ｅ）の摺動作用は、作業者が光源部２００を上方（天井方向）に持ち上げると、バネ部１３０は自ずと元の形状に戻ろうとすることによるが、作業者はバネ部１３０を気にすることなく、バネ部１３０は連結金具２５０に対して摺動しながら元の形状に戻る。 ((C) of FIG. 11)
Next, in FIG. 11C, when the operator lifts the light source part 200 upward (toward the ceiling), the back surface of the arc part E of the spring part 130 is the opening edge part 250a- of the spring insertion hole 250a-1. It slides with respect to 1-1 by the restoring force of the spring. The sliding action of the spring part 130 (arc part E) is that when the operator lifts the light source part 200 upward (toward the ceiling), the spring part 130 will naturally return to its original shape. Without worrying about the spring portion 130, the spring portion 130 returns to its original shape while sliding with respect to the connecting fitting 250.

（図１１の（ｄ））
次に、図１１の（ｄ）において、作業者が、本体部１００の光源挿入部１１３ａ（図１４）に光源部２００のカバー爪部２３０ａの部分を差し込むと、カバー当接部２３０ｂが、光源受部１１３ｂに当接する。このときバネ部１３０は、光源部２００の装着状態が完了する直前では、第３曲げ部Ｍ３（摺動制御部、摺動抑制部）がバネ受部２５０ａ−２と当接し、円弧部Ｅの摺動が抑制される。そして作業者が光源部２００の本体部１００への差し込みを完了（光源部２００の装着完了）すると、バネ部１３０の第４曲げ部Ｍ４の内側箇所Ｍ４−１が、連結金具２５０の開口縁部２５０ａ−１−１と押し合う状態で、開口縁部２５０ａ−１−１に対して位置決めされる（図１２）。このとき、バネ部１３０が内側箇所Ｍ４−１で開口縁部２５０ａ−１−１を支持する際のバネ定数は、図１１の（ｂ）において屈曲部Ｋで光源部２００を支持する際のバネ定数に対して著しく大きい。これは、バネ部１３０では第１平坦部Ｌ１（固定）が本体部１００に固定されるので、第１平坦部Ｌ１を固定端とする片持ち梁として大まかに見積もることができる。バネ部１３０では、ほとんど弾性変形しない第１曲げ部Ｍ１と第４曲げ部Ｍ４との直線距離（スパン）は、第１曲げ部Ｍ１と屈曲部Ｋとの距離（スパン）の、例えば１／５〜１／６程度である。片持ち梁ではスパンはバネ定数に３乗で影響する。よって、第４曲げ部Ｍ４におけるバネ定数は、１／５であれば屈曲部Ｋにおけるバネ定数の１２５倍であり、１／６であれば屈曲部Ｋにおけるバネ定数の２１６倍である。このため、作業者が光源部２００を本体部１００への差し込みを完了すると、バネ部１３０の第４曲げ部Ｍ４の内側箇所Ｍ４−１が、連結金具２５０の開口縁部２５０ａ−１−１を支持することができる。つまり第４曲げ部Ｍ４の内側箇所Ｍ４−１で、光源部２００の自重を支持することができる。 ((D) in FIG. 11)
Next, in FIG. 11D, when the operator inserts the cover claw portion 230a portion of the light source portion 200 into the light source insertion portion 113a (FIG. 14) of the main body portion 100, the cover contact portion 230b It contacts the receiving part 113b. At this time, immediately before the mounting state of the light source unit 200 is completed, the spring unit 130 is in contact with the spring receiving unit 250a-2 and the third bending unit M3 (sliding control unit, sliding suppression unit). Sliding is suppressed. When the operator completes the insertion of the light source unit 200 into the main body unit 100 (the mounting of the light source unit 200 is completed), the inner portion M4-1 of the fourth bent portion M4 of the spring unit 130 is the opening edge of the connection fitting 250. In a state of pressing against 250a-1-1, it is positioned with respect to the opening edge 250a-1-1 (FIG. 12). At this time, the spring constant when the spring portion 130 supports the opening edge portion 250a-1-1 at the inner portion M4-1 is a spring constant when the light source portion 200 is supported by the bent portion K in FIG. It is significantly larger than the constant. This can be roughly estimated as a cantilever having the first flat portion L1 as a fixed end because the first flat portion L1 (fixed) is fixed to the main body portion 100 in the spring portion 130. In the spring portion 130, the linear distance (span) between the first bent portion M1 and the fourth bent portion M4 that hardly elastically deforms is, for example, 1/5 of the distance (span) between the first bent portion M1 and the bent portion K. About 1/6. In cantilever beams, the span affects the spring constant by the third power. Therefore, if the spring constant in the fourth bent portion M4 is 1/5, it is 125 times the spring constant in the bent portion K, and if it is 1/6, it is 216 times the spring constant in the bent portion K. For this reason, when the operator completes the insertion of the light source unit 200 into the main body unit 100, the inner portion M 4-1 of the fourth bent portion M 4 of the spring unit 130 moves the opening edge 250 a-1-1 of the connection fitting 250. Can be supported. That is, the weight of the light source unit 200 can be supported by the inner portion M4-1 of the fourth bending portion M4.

（光源部２００の取り外し作業）
次に、光源部２００を本体部１００から取り外す方法について説明する。光源部２００の取り外し方法は図１１で述べた取り付け方法の逆の手順になる。
（１）図１１の（ｄ）のように、作業者は、光源部２００が本体部１００に取り付けられた状態から、光源部２００を略水平に引き下げる。
（２）作業者は、光源部２００を図１１の（ｃ）を経て（ｂ）の状態まで引き下げ、バネ部１３０の屈曲部Ｋを連結金具２５０のバネ挿入孔２５０ａ−１から外す。
（３）以上の手順で、作業者は、本体部１００から光源部２００を取り外す。 (Removal work of the light source unit 200)
Next, a method for removing the light source unit 200 from the main body unit 100 will be described. The method of removing the light source unit 200 is the reverse of the mounting method described in FIG.
(1) As shown in FIG. 11D, the operator pulls the light source unit 200 substantially horizontally from the state in which the light source unit 200 is attached to the main body unit 100.
(2) The operator lowers the light source unit 200 to the state of (b) through (c) of FIG. 11, and removes the bent portion K of the spring unit 130 from the spring insertion hole 250 a-1 of the connection fitting 250.
(3) The operator removes the light source unit 200 from the main body unit 100 by the above procedure.

次に、取付時における、バネ部１３０の弾性作用（作用効果）に関して説明をする。図１２は、本実施の形態１の取付時における、バネ部１３０の第２平坦部Ｌ２（可動軸）の周辺の拡大図である。図１２において、点線は弾性変形していない状態（図１１の（ａ）の状態）のバネ部１３０（バネ部１３０ａとする）を示し、実線は内側箇所Ｍ４−１で光源部２００を保持している弾性変形状態（図１１の（ｄ）の状態）のバネ部１３０（バネ部１３０ｂとする）を示している。 Next, the elastic action (action effect) of the spring part 130 at the time of attachment will be described. FIG. 12 is an enlarged view around the second flat portion L2 (movable shaft) of the spring portion 130 when the first embodiment is attached. In FIG. 12, a dotted line indicates the spring part 130 (referred to as a spring part 130a) in a state where it is not elastically deformed (state shown in FIG. 11A), and a solid line holds the light source part 200 at the inner portion M4-1. 11 shows a spring portion 130 (referred to as a spring portion 130b) in an elastically deformed state (the state shown in FIG. 11D).

図１２において、バネ部１３０ｂ（実線）では、内側箇所Ｍ４−１（黒丸で示した）が、バネ部１３０ａ（点線）の内側箇所Ｍ４−１相当箇所（バネ部１３０ｂ（実線）で内側箇所Ｍ４−１に印をつけてバネ部１３０ａ（点線）の状態に戻したときの印の位置）と比較すると、以下のようになる。つまりバネ部１３０ｂ（実線）は、第１平坦部Ｌ１の方向へ水平に寸法Ａ、下側方向に寸法Ｂだけ弾性変形した状態で、光源部２００（連結金具２５０）を保持している。 In FIG. 12, in the spring part 130b (solid line), the inner part M4-1 (shown by a black circle) is an equivalent part of the inner part M4-1 of the spring part 130a (dotted line) (the inner part M4 in the spring part 130b (solid line)). Compared with the mark -1 and the position of the mark when the spring part 130a (dotted line) is returned to the state), the result is as follows. That is, the spring part 130b (solid line) holds the light source part 200 (the connecting metal fitting 250) in a state where it is elastically deformed by the dimension A horizontally in the direction of the first flat part L1 and the dimension B in the lower direction.

（バネ部１３０のへたりと弾性力との関係）
バネ部１３０は図１１の（ｂ）あるいは後述の図１３のように使用される。よってバネ部１３０にへたりが生じると図６における第２角度θ３が大きくなる方向に影響するが、この影響は図１２において寸法Ａが増加する方向に働き、結果としてへたりが生じた際のバネ部１３０が光源部２００（連結金具２５０）を支持する弾性力の低下を抑制できる。このように、バネ部１３０の形状的特徴によって、バネ部１３０に劣化（へたり）が発生しても、弾性力の低下をもたらすことなく（へたりにより、むしろ弾性力（たわみ））が増加する）、光源部２００を保持できる効果を有する。なお、連結金具２５０はバネ部１３０と連結するものであり、寸法Ａ、寸法Ｂがマイナスにならないものであれば、本実施の形態１以外の形状のものでも良い。 (Relationship between spring part 130 sag and elastic force)
The spring portion 130 is used as shown in FIG. 11B or FIG. Therefore, when the spring portion 130 is sagged, it affects the direction in which the second angle θ3 in FIG. 6 increases. This effect acts in the direction in which the dimension A increases in FIG. 12, and as a result sag occurs. The spring part 130 can suppress a decrease in the elastic force that supports the light source part 200 (connecting bracket 250). As described above, due to the shape characteristics of the spring portion 130, even if the spring portion 130 is deteriorated (sagging), the elastic force is not reduced (the elastic force (deflection) rather than the sag). The light source unit 200 can be held. The connection fitting 250 is connected to the spring portion 130, and may have a shape other than that of the first embodiment as long as the dimension A and the dimension B do not become negative.

実施の形態１は、作業者が本体部１００に光源部２００を取り付ける際に、バネ部１３０の円弧部Ｅが光源部２００に設けられた連結金具２５０を復元力で自ら摺動する。そして、作業者が光源部２００を最終的な装着状態とする直前で、第３曲げ部Ｍ３が円弧部Ｅの摺動を抑制（制御）し、最後の装着時には、内側箇所Ｍ４−１位置における大きいバネ定数によって光源部２００を支持できる構成である。この構成によって、本体部１００と光源部２００とを確実に、かつ簡単に連結できる連結機構、及びその連結機構を備えた照明器具を提供できる。
またこの連結機構では、図１１の（ｂ）のように作業者の両手が自由になると共に、光源部２００を天井方向に持ち上げることで、内側箇所Ｍ４−１が摺動してバネ部１３０が元の形状に戻ろうとする。よって光源部２００の取り付け、及び取り外しの作業効率が向上する。 In the first embodiment, when the worker attaches the light source unit 200 to the main body unit 100, the arc portion E of the spring unit 130 slides on the connection fitting 250 provided on the light source unit 200 by a restoring force. And just before an operator puts the light source part 200 into a final mounting state, the 3rd bending part M3 suppresses (controls) the sliding of the circular arc part E, and at the time of the last mounting | wearing, in the inner location M4-1 position. The light source unit 200 can be supported by a large spring constant. With this configuration, it is possible to provide a connection mechanism that can reliably and easily connect the main body unit 100 and the light source unit 200 and a lighting fixture that includes the connection mechanism.
Further, in this connection mechanism, both hands of the operator are freed as shown in FIG. 11B, and the light source part 200 is lifted in the ceiling direction so that the inner part M4-1 slides and the spring part 130 is moved. Try to return to its original shape. Therefore, the work efficiency of attaching and removing the light source unit 200 is improved.

実施の形態１の照明器具１０００では、本体部１００への光源部２００の取り付けをバネ部１３０と連結金具２５０とで行うことができるので部品の削減を図ることができる。また照明器具１０００では専用治具なしで取付取り外しができるので作業性が向上する。 In the lighting fixture 1000 of Embodiment 1, the light source part 200 can be attached to the main body part 100 with the spring part 130 and the connecting metal fitting 250, so that the number of parts can be reduced. In addition, since the lighting fixture 1000 can be attached and detached without a dedicated jig, workability is improved.

また、本実施の形態１では、逆富士形の照明器具１０００について説明をしたが、本体部と光源部が一体になっておらず、光源部を本体部に取り付けることが必要な照明器具であれば、埋込型、直付け型でもよく、天井スクエア型など略正方形状をしたものでもよい。 Further, in Embodiment 1, the reverse Fuji type lighting fixture 1000 has been described. However, the main body portion and the light source portion are not integrated, and the lighting fixture needs to be attached to the main body portion. For example, it may be an embedded type, a direct-attached type, or a substantially square shape such as a ceiling square type.

また、本実施の形態１では、光源部２００が図１８に示すように略平行に取り付けられる取付機構の説明をしたが、片側（図２の２個のバネ部１３０の一方）から取り付けを行なってもよい。 In the first embodiment, the mounting mechanism in which the light source unit 200 is mounted substantially in parallel as shown in FIG. 18 has been described. However, the mounting is performed from one side (one of the two spring units 130 in FIG. 2). May be.

また、本実施の形態１では、バネ部１３０が照明器具１０００の長手方向へ２箇所配置される取付機構を説明したが、図１３に示す照明器具２０００のように、長手片側が引っ掛けによる係合で、もう一方がバネ部による取り付けであっても良い。なお照明器具２０００を示す図１３では、本体部及び光源部の構成が照明器具１０００と異なるため、本体部を本体部１００’と記し、光源部を光源部２００’と記している。 Further, in the first embodiment, the mounting mechanism in which the spring portion 130 is disposed at two positions in the longitudinal direction of the lighting fixture 1000 has been described. However, as in the lighting fixture 2000 shown in FIG. Then, the other may be attached by a spring part. In FIG. 13 showing the lighting fixture 2000, the configuration of the main body portion and the light source portion is different from that of the lighting fixture 1000, so the main body portion is indicated as the main body portion 100 'and the light source portion is indicated as the light source portion 200'.

また、本実施の形態１では、対になるバネ部１３０がお互いに反対方向へ開くように可動する配置に関して説明をおこなったが、互いに向かい合って開くよう可動する配置でもよく、同じ方向へ開くような配置（例えば図３で２個のバネ部１３０が同じ方向（長手方向を示す矢印側）へ向く）しても良い。 In the first embodiment, the arrangement in which the pair of spring portions 130 are movable so as to open in opposite directions has been described. However, the arrangement may be such that the spring portions 130 are opened opposite to each other and open in the same direction. (For example, in FIG. 3, the two spring portions 130 may face in the same direction (the arrow side indicating the longitudinal direction)).

なお、実施の形態１では本体部１００にバネ部１３０を設け、光源部２００に連結金具２５０を設ける仕様について説明を行なったが、本体部１００が連結金具２５０を備え、光源部２００がバネ部１０を備える仕様でもよい。 In the first embodiment, the specifications for providing the main body 100 with the spring 130 and the light source 200 with the connection fitting 250 have been described. However, the main body 100 includes the connection fitting 250, and the light source 200 has the spring. The specification provided with 10 may be sufficient.
