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, instead of fluorescent lighting fixtures, lighting fixtures using LEDs as a light source have been used. Similar to conventional lighting fixtures for fluorescent lamps, some lighting fixtures that use LEDs have a light source portion in which LEDs are arranged so that they can be detachably fixed to a main body that is fixed to a surface to be attached such as a ceiling. ..

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）。 The method of attaching the light source portion and the main body portion is that the light source portion is a lighting fixture that is inserted and attached into a recess provided in the main body portion, and the spring member provided on the side surface of the light source portion is elastically deformed. There is one that is inserted into the recess and engages with a metal fitting provided inside the recess to fix the light source portion to connect the light source portion and the main body portion (for example, Patent Document 1).
In some cases, a light source unit equipped with a lighting device is attached to the main body portion, and a groove portion is formed on the entire side surface of the light source unit provided with the lighting device, and the main body portion has a claw portion that engages with the entire length of the light source portion groove portion. Is provided, and by engaging with the entire side surface, the weight load of the light source portion is dispersed and the deformation of the claw portion is prevented (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 lighting fixture of Patent Document 1, the light source portion and the main body portion are connected by a plurality of spring members, and if the plurality of spring members are not inserted into the corresponding fixing brackets at the same time, stress is applied to the spring portion, and the spring portion is deformed and illuminated. There is a risk of equipment failure.
Further, the luminaire of Patent Document 2 is fitted with a groove portion and a claw portion in the entire side surface length. Therefore, when the light source portion is removed from the main body portion, it is necessary to simultaneously press the fitted total length to release the mated state between the groove portion and the claw portion, and a special jig is required.

（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。

Next, the work of attaching the light source portion 200 (connecting metal fitting 250) to the main body portion 100 (spring portion 130) attached to the ceiling will be described with reference to FIG.
In FIG. 11,
(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 bent portion K is connected to the connecting metal fitting 250 of the light source portion 200 in a state where the spring portion 130 is elastically deformed so that the operator increases the curvature of the arc portion E of the spring portion 130. .. (C) shows a state in which the back side of the arc portion E slides with respect to the opening edge portion 250a-1-1 of the connecting metal fitting 250.
(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)
In FIG. 11A, in the main body 100, the first flat portion L1 of the spring portion 130 is in contact with the mounting portion 112 and is fixed by the screw 116 (same as in FIG. 5). The light source unit 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) in FIG. 11)
Next, in FIG. 11B, the spring portion 130 is in a state in which the arc portion E (sliding portion) is perpendicular to the mounting portion 112 with the second flat portion L2 (movable shaft) as the center of rotation. It is in a state of being elastically deformed. The operator passes the spring portion 130 through the bent portion K of the spring portion 130 through the spring insertion hole 250a-1 for both connecting fittings 250. The operator hooks the bent portion K of the spring portion 130 on the opening edge portion 250a-1-1 of the spring insertion hole 250a-1 (FIG. 9) of the connecting metal fitting 250, and suspends the light source portion 200 from the main body portion 100. .. As shown in FIG. 3, two spring portions 130 are arranged at both ends of the main body 100, and as shown in FIG. 18, the light source portion 200 has two spring portions 130 on the main body 100. On the other hand, it can be held in a substantially parallel state. At the time of construction of the luminaire 1000, the operator 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) in FIG. 11)
Next, in FIG. 11C, when the operator lifts the light source portion 200 upward (toward the ceiling), the back surface of the arc portion E of the spring portion 130 is exposed to the opening edge portion 250a of the spring insertion hole 250a-1. It slides with respect to 1-1 due to the restoring force of the spring. The sliding action of the spring portion 130 (arc portion E) is due to the fact that when the operator lifts the light source portion 200 upward (toward the ceiling), the spring portion 130 naturally tries to return to the original shape, but the operator The spring portion 130 returns to its original shape while sliding with respect to the connecting metal 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) in FIG. 11)
Next, in FIG. 11D, when the operator inserts the portion of the cover claw portion 230a 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 becomes the light source. It comes into contact with the receiving portion 113b. At this time, in the spring portion 130, immediately before the mounting state of the light source portion 200 is completed, the third bending portion M3 (sliding control portion, sliding suppressing portion) comes into contact with the spring receiving portion 250a-2, and the arc portion E Sliding is suppressed. Then, when the operator completes the insertion of the light source unit 200 into the main body 100 (the installation of the light source unit 200 is completed), the inner portion M4-1 of the fourth bent portion M4 of the spring portion 130 becomes the opening edge portion of the connecting metal fitting 250. It is positioned with respect to the opening edge 250a-1-1 while being pressed against the 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 the spring constant when the bending portion K supports the light source portion 200 in FIG. 11B. Remarkably large relative to the constant. This can be roughly estimated as a cantilever with the first flat portion L1 as the 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, which is hardly elastically deformed, is, for example, 1/5 of the distance (span) between the first bent portion M1 and the bent portion K. It is about 1/6. For cantilever beams, the span affects the spring constant by the cube. Therefore, the spring constant in the fourth bent portion M4 is 125 times the spring constant in the bent portion K if it is 1/5, and 216 times the spring constant in the bent portion K if it is 1/6. Therefore, when the operator completes the insertion of the light source portion 200 into the main body portion 100, the inner portion M4-1 of the fourth bent portion M4 of the spring portion 130 presses the opening edge portion 250a-1-1 of the connecting metal 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 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 100 will be described. Light source unit 200
The removal method is the reverse of the mounting method described in FIG.
(1) As shown in FIG. 11D, the operator pulls down 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 pulls down the light source unit 200 through (c) of FIG. 11 to the state of (b), and removes the bent portion K of the spring portion 130 from the spring insertion hole 250a-1 of the connecting metal fitting 250.
(3) In the above procedure, the operator removes the light source unit 200 from the main body unit 100.

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 mounting 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 at the time of mounting according to the first embodiment. In FIG. 12, the dotted line shows the spring portion 130 (referred to as the spring portion 130a) in the state of not being elastically deformed (the state of (a) in FIG. 11), and the solid line holds the light source portion 200 at the inner portion M4-1. The spring portion 130 (referred to as the spring portion 130b) in the elastically deformed state (state of (d) in FIG. 11) is shown.

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 portion 130b (solid line), the inner portion M4-1 (indicated by a black circle) corresponds to the inner portion M4-1 of the spring portion 130a (dotted line) (the inner portion M4 in the spring portion 130b (solid line)). -1 is marked and the position of the mark when the spring portion 130a (dotted line) is returned to the state) is as follows. That is, the spring portion 130b (solid line) holds the light source portion 200 (connecting metal fitting 250) in a state of being elastically deformed by the dimension A horizontally 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。 (Relationship between the settling of the spring portion 130 and the elastic force)
The spring portion 130 is used as shown in FIG. 11B or FIG. 13 described later. Therefore, when the spring portion 130 is settled, it affects the direction in which the second angle θ3 in FIG. 6 increases, but this effect acts in the direction in which the dimension A increases in FIG. 12, and as a result, the settling occurs. It is possible to suppress a decrease in the elastic force of the spring portion 130 that supports the light source portion 200 (connecting metal fitting 250). In this way, due to the shape characteristics of the spring portion 130, even if the spring portion 130 is deteriorated (sagging), the elastic force (deflection) is increased without causing a decrease in the elastic force (due to the sagging). It has the effect of holding the light source unit 200. The connecting metal 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 dimensions A and 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 operator attaches the light source portion 200 to the main body portion 100, the arc portion E of the spring portion 130 slides on the connecting metal fitting 250 provided on the light source portion 200 by the restoring force. Then, just before the operator puts the light source unit 200 in the final mounting state, the third bending portion M3 suppresses (controls) the sliding of the arc portion E, and at the time of the final mounting, the inner portion 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 connecting mechanism capable of reliably and easily connecting the main body 100 and the light source 200, and a lighting fixture provided with the connecting mechanism.
Further, in this connecting mechanism, as shown in FIG. 11B, both hands of the operator are freed, and by lifting the light source portion 200 toward the ceiling, the inner portion M4-1 slides and the spring portion 130 is moved. Trying to return to its 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 of the first embodiment, since the light source portion 200 can be attached to the main body portion 100 by the spring portion 130 and the connecting metal fitting 250, the number of parts can be reduced. Further, since the lighting fixture 1000 can be attached and detached without a special 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 the first embodiment, the inverted Fuji type luminaire 1000 has been described, but the luminaire may be one in which the main body and the light source are not integrated 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。 Further, 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, but mounting is performed from one side (one of the two spring portions 130 in FIG. 2). You may.

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 portions 130 are arranged at two locations in the longitudinal direction of the luminaire 1000 has been described, but as in the luminaire 2000 shown in FIG. 13, one side of the spring is engaged by hooking. Then, the other side may be attached by a spring part. In FIG. 13 showing the luminaire 2000, since the configurations of the main body and the light source are different from those of the luminaire 1000, the main body is referred to as the main body 100'and the light source is referred to as the light source 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。 Further, in the first embodiment, the arrangement in which the paired spring portions 130 are movable so as to open in opposite directions has been described, but the arrangement in which the paired spring portions 130 are movable so as to open facing each other may be used so as to 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 specification that the spring portion 130 is provided in the main body portion 100 and the connecting metal fitting 250 is provided in the light source portion 200 has been described. However, the main body portion 100 is provided with the connecting metal fitting 250 and the light source portion 200 is provided with the spring portion. A specification including 10 may be used.
