Description

近年、蛍光灯用照明器具に変わって、ＬＥＤを光源とした照明器具が使用されている。ＬＥＤを使用する照明器具は、従来の蛍光灯用照明器具と同様に、天井などの被取付面に固定された本体部に、ＬＥＤが配置された光源部が脱着可能に固定されるものがある。 In recent years, lighting fixtures using LEDs as light sources have been used instead of fluorescent lighting fixtures. Some lighting fixtures using LEDs, like conventional lighting fixtures for fluorescent lamps, include a main body fixed to a mounting surface such as a ceiling, and a light source unit in which the LEDs are arranged is detachably fixed. .

光源部と本体部との取付方法には、光源部が、本体部に設けられた窪みに挿入されて取り付けられる照明器具であって、光源部の側面に設けられたバネ部材が弾性変形しながら窪みに挿入され、窪み内部に設けられ光源部を固定する金具と係合し、光源部と本体部が連結されるものがある（例えば、特許文献１）。
また、点灯装置を備えた光源部が本体部に取り付けられたものもあり、点灯装置を備えた光源部の側面全長に溝部が形成され、本体部には光源部溝部全長と係合する爪部が設けられており、側面全長で係合することで、光源部の重量負荷を分散化し、爪部の変形防止を行なっているものもある（例えば、特許文献２）。 In the method of mounting the light source unit and the main body unit, the light source unit is a lighting fixture that is inserted and mounted in a recess provided in the main body unit, and a spring member provided on a side surface of the light source unit is elastically deformed. There is one that is inserted into a depression, engages with a metal fitting provided inside the depression to fix the light source unit, and connects the light source unit and the main body unit (for example, Patent Document 1).
There is also a light source unit provided with a lighting device attached to the main body, a groove is formed on the entire side surface of the light source unit provided with the lighting device, and a claw portion that engages with the entire length of the light source unit groove on the main body. In some cases, by engaging the entire length of the side surface, the weight load of the light source unit is dispersed and the claw portion is prevented from being deformed (for example, Patent Document 2).

特許文献１の照明器具は複数のバネ部材により光源部と本体部が連結されており、複数のバネ部材を同時に対応する固定金具に差し込まないとバネ部に応力がかかり、バネ部の変形や照明器具の故障をもたらすおそれがある。
また、特許文献２の照明器具は、側面全長にて、溝部と爪部と嵌合している。その為、光源部を本体部から取り外すときは、嵌合した全長を同時に押圧し溝部と、爪部との嵌合状態の解徐を要し、専用の治具が必要となる。 In the luminaire of Patent Document 1, the light source unit and the main body are connected by a plurality of spring members. If the plurality of spring members are not inserted into the corresponding fittings at the same time, stress is applied to the spring unit, and deformation and illumination of the spring unit are caused. There is a risk of equipment failure.
Further, in the lighting device of Patent Document 2, the groove and the claw are fitted over the entire side surface.

(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 parts 130)
One spring portion 130 is provided on each of the left and right sides of a central axis 117 (FIG. 3) that bisects the longitudinal direction of the main body portion 100. Each of the spring portions 130 is arranged such that the first flat portion L1 as a fixed portion faces the central axis 117 and the bent portion K faces the lid 115.

（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。 (Attaching work of the light source unit 200)
Next, with reference to FIG. 11, a description will be given of an operation in which an operator attaches the light source unit 200 (the connection fitting 250) to the main body unit 100 (the spring unit 130) attached to the ceiling.
In FIG.
(A) shows a state before the light source unit 200 is attached to the main body unit 100.
(B) shows a state in which the worker connects the bent portion K to the connection fitting 250 of the light source unit 200 in a state where the spring portion 130 is elastically deformed so that the curvature of the arc portion E of the spring portion 130 is increased. . (C) shows a state where the back side of the arc portion E slides with respect to the opening edge portion 250a-1-1 of the connection fitting 250.
(D) shows a state where 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) of FIG. 11)
11A, in the main body 100, the first flat portion L1 of the spring portion 130 abuts on the mounting portion 112 and is fixed by the screw 116 (same as FIG. 5). The light source 200 is not attached to the main body 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 (b) of FIG. 11, in the spring portion 130, the arc portion E (sliding portion) is in a vertical state with respect to the mounting portion 112 with the second flat portion L <b> 2 (movable shaft) as the center of rotation. Is in a state of being elastically deformed. The operator causes the spring portion 130 to pass through the spring insertion hole 250a-1 from the bent portion K of the spring portion 130 for both connection fittings 250. The operator hooks the bent portion K of the spring portion 130 on the opening edge 250a-1-1 of the spring insertion hole 250a-1 (FIG. 9) of the connection fitting 250, and suspends the light source unit 200 on the main body 100. . As shown in FIG. 3, the spring section 130 has two spring sections 130 arranged at both ends of the main body section 100. As shown in FIG. 18, the light source section 200 is connected to the main body section 100 by the two spring sections 130. It can be held in a substantially parallel state. At the time of the installation of the lighting fixture 1000, the worker can connect the connector in the state of FIG. 18 without having to support the light source unit 200 with both hands or one hand.

（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 (c) of FIG. 11, when the operator lifts the light source unit 200 upward (toward the ceiling), the back surface of the arc portion E of the spring portion 130 is closed by the opening edge 250a- of the spring insertion hole 250a-1. 1-1, it slides by the restoring force of the spring. The sliding action of the spring portion 130 (circular arc portion E) is based on the fact that when the operator lifts the light source unit 200 upward (toward the ceiling), the spring portion 130 naturally attempts to return to the original shape. The spring portion 130 returns to the original shape while sliding with respect to the connection fitting 250 without worrying about the spring portion 130.

（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) of FIG. 11)
Next, in FIG. 11D, when the worker inserts the cover claw 230a of the light source 200 into the light source insertion portion 113a (FIG. 14) of the main body 100, the cover contact portion 230b is It comes into contact with the receiving portion 113b. At this time, immediately before the mounting state of the light source unit 200 is completed, the spring portion 130 is brought into contact with the third bent portion M3 (sliding control portion, sliding suppression portion) against the spring receiving portion 250a-2, and Sliding is suppressed. Then, when the worker 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 inside portion M4-1 of the fourth bent portion M4 of the spring unit 130 becomes the opening edge of the connection fitting 250. It is positioned with respect to the opening edge 250a-1-1 in a state of pressing against the opening 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 location M4-1 is the spring constant when the light source portion 200 is supported by the bent portion K in FIG. Significantly larger for constants. Since the first flat portion L1 (fixed) is fixed to the main body 100 in the spring portion 130, it can be roughly estimated as a cantilever having the first flat portion L1 as a fixed end. In the spring portion 130, the linear distance (span) between the first bent portion M1 and the fourth bent portion M4 that is hardly elastically deformed is, for example, 1/5 of the distance (span) between the first bent portion M1 and the bent portion K. About 1/6. For a cantilever, the span affects the spring constant by the third power. Therefore, if the spring constant at the fourth bent portion M4 is 1/5, it is 125 times the spring constant at the bent portion K, and if it is 1/6, it is 216 times the spring constant at the bent portion K. For this reason, when the worker completes the insertion of the light source unit 200 into the main body 100, the inner part M4-1 of the fourth bent part M4 of the spring part 130 is moved to the opening edge 250a-1-1 of the connection fitting 250. Can be supported. That is, the self-weight of the light source unit 200 can be supported at the location M4-1 inside the fourth bent 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 of 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 procedure of the mounting method described with reference to FIG.
(1) As shown in FIG. 11D, the worker pulls down the light source unit 200 substantially horizontally from a state in which the light source unit 200 is attached to the main body unit 100.
(2) The worker pulls down the light source section 200 to the state shown in FIG. 11B through FIG. 11C, and removes the bent portion K of the spring section 130 from the spring insertion hole 250a-1 of the connection fitting 250.
(3) The worker removes the light source unit 200 from the main 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 portion 130 at the time of attachment will be described. FIG. 12 is an enlarged view of the periphery of the second flat portion L2 (movable shaft) of the spring portion 130 when the first embodiment is attached. 12, the dotted line shows the spring portion 130 (referred to as a spring portion 130a) in a state where it is not elastically deformed (the state shown in FIG. 11A), and the solid line holds the light source unit 200 at the inner part M4-1. 11 shows a spring portion 130 (referred to as a spring portion 130b) in an elastically deformed state (a 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 equivalent to 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 (-1), the position of the mark when the state is returned to the state of the spring portion 130a (dotted line) is as follows. That is, the spring portion 130b (solid line) holds the light source portion 200 (the connection fitting 250) in a state where it is elastically deformed by the dimension A in the direction of the first flat portion L1 and the dimension B in the downward 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。 (Relation between set of spring portion 130 and elastic force)
The spring portion 130 is used as shown in FIG. 11B or FIG. 13 described later. Therefore, when the set is generated in the spring portion 130, it affects the direction in which the second angle θ3 in FIG. 6 increases, but this influence acts in the direction in which the dimension A increases in FIG. 12, and as a result, when the set is generated. It is possible to suppress a decrease in the elastic force of the spring section 130 supporting the light source section 200 (the connection fitting 250). As described above, due to the shape characteristic of the spring portion 130, even if the spring portion 130 is deteriorated (set), the elastic force is increased (rather than set, the elastic force (deflection) is increased) without reducing the elastic force. Yes, 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 the first embodiment as long as the dimensions A and B are not 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 operator attaches the light source unit 200 to the main body unit 100, the circular 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. Then, immediately before the worker brings the light source unit 200 into the final mounted state, the third bent portion M3 suppresses (controls) the sliding of the circular arc portion E, and at the time of the last mounting, the third bent portion M3 is at the inner position M4-1. 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 including the connection mechanism.
In this connection mechanism, both hands of the operator are free as shown in FIG. 11B, and the light source unit 200 is lifted in the ceiling direction, so that the inner part M4-1 slides and the spring unit 130 is moved. Try to return to the original shape. Therefore, the work efficiency of attaching and detaching 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 according to the first embodiment, the light source unit 200 can be attached to the main body unit 100 by the spring unit 130 and the connection fitting 250, so that the number of components 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。 In Embodiment 1, the inverted Fuji-shaped lighting fixture 1000 has been described. However, the lighting fixture 1000 is not necessarily integrated with the main body and the light source needs to be attached to the main body. For example, it may be an embedded type, a direct mounting 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。 Also, in the first embodiment, the attachment mechanism in which the light source unit 200 is attached substantially in parallel as shown in FIG. 18 has been described, but attachment is performed from one side (one of the two spring units 130 in FIG. 2).
