Description

本発明は、埋込型照明器具に関し、より詳しくは、埋込型照明器具の取付壁部への取付構造に関する。   The present invention relates to an embedded luminaire, and more particularly, to a structure for attaching an embedded luminaire to a mounting wall.

従来、天井等の取付壁部に形成された取付穴に埋め込まれて設置される、埋込型照明器具が知られている。この種の埋込型照明器具として、光を出射させる開口部が下部に形成された器具本体と、器具本体の内部に設けられた光源部と、開口部の外周縁に形成されたフランジとを備え、固定手段として、取付バネを備えたものが知られている（例えば、特許文献１参照。）。   2. Description of the Related Art Conventionally, there has been known an embedded lighting fixture that is installed by being embedded in a mounting hole formed in a mounting wall portion such as a ceiling. As this type of embedded luminaire, an instrument main body in which an opening for emitting light is formed in the lower part, a light source part provided inside the instrument main body, and a flange formed on the outer periphery of the opening. The thing provided with the attachment spring as an equipped and fixing means is known (for example, refer patent document 1).

特許文献１の取付バネは、フランジの周方向に複数配設され、フランジの上方から斜め上方に向けて形成されており、器具本体と取付バネとの固定は、取付バネの幅方向中心線上に設けられる係止孔が、器具本体側の係止突起部に係止することにより行われている。このため特許文献１の取付バネは、器具本体に対して左右に振れやすく、取付バネと器具本体との固定が不安定であるという問題がある（特許文献１の図１参照。）。   A plurality of mounting springs of Patent Document 1 are arranged in the circumferential direction of the flange and are formed obliquely upward from above the flange, and the fixture body and the mounting spring are fixed on the center line in the width direction of the mounting spring. The provided locking hole is performed by locking to the locking projection on the instrument body side. For this reason, the attachment spring of patent document 1 has the problem that it is easy to swing right and left with respect to an instrument main body, and fixation of an attachment spring and an instrument main body is unstable (refer FIG. 1 of patent document 1).

一方、取付バネによる取付力は、埋込型照明器具の重さを支えるだけの強度では不足であり、埋込型照明器具の上部に被せられた断熱材などの重みが加わっても容易に外れない強度を持たせる必要がある。一般に取付バネは、薄い取付壁部（例えば、５ｍｍ）から厚い取付壁部（例えば、２５ｍｍ）まで対応できるが、取付バネの取付力は、取付壁部の厚みによって変動し、薄い取付壁部の場合は取付力は大きいが、厚い取付壁部の場合は取付力は小さくなる。   On the other hand, the mounting force by the mounting spring is insufficient to support the weight of the embedded luminaire, and easily disengages even when weight is added to the top of the embedded luminaire. There is no need to have strength. In general, the mounting spring can handle a thin mounting wall (for example, 5 mm) to a thick mounting wall (for example, 25 mm). However, the mounting force of the mounting spring varies depending on the thickness of the mounting wall, In this case, the mounting force is large, but in the case of a thick mounting wall, the mounting force is small.

特許文献１の取付バネは、取付壁部が薄い場合と厚い場合とで、一定以上の取付力の強度を保つために、器具本体に対する取付バネの固定位置を調整できるように構成されている。しかしながら、特許文献１では、取付バネの幅方向中心線上に設けられる係止孔の横をガイドで押さえられているため、係止孔が器具本体側の係止突起部に一旦係止すると外れ難く、器具本体に対する取付バネの固定位置を調整し難いという問題がある（特許文献１の図１参照。）。   The mounting spring of Patent Document 1 is configured to be able to adjust the fixing position of the mounting spring with respect to the instrument body in order to maintain a certain level of mounting force strength when the mounting wall is thin or thick. However, in Patent Document 1, since the side of the locking hole provided on the center line in the width direction of the mounting spring is pressed by the guide, it is difficult to come off once the locking hole is locked to the locking projection on the instrument body side. There is a problem that it is difficult to adjust the fixing position of the mounting spring with respect to the instrument body (see FIG. 1 of Patent Document 1).

次に、器具本体１１と取付バネ３１との組み付けについて説明する。図１、図２に示すように、取付バネ３１の差込部３２を器具本体１１の保持部２１に差し込む。この際、図４に示すように、差込部主体３６が第１ガイド部材２４のガイド面２６側に配置され、操作部３５が第１ガイド部材２４の外側に配置されるように、差込部３２を保持部２１に差し込むようにする。   Next, assembly of the instrument body 11 and the attachment spring 31 will be described. As shown in FIGS. 1 and 2, the insertion portion 32 of the attachment spring 31 is inserted into the holding portion 21 of the instrument body 11. At this time, as shown in FIG. 4, the insertion portion main body 36 is disposed on the guide surface 26 side of the first guide member 24, and the operation portion 35 is disposed on the outer side of the first guide member 24. The part 32 is inserted into the holding part 21.

差込部３２が保持部２１に差し込まれた状態では、差込部主体３６は、第１ガイド部材２４のガイド面２６に当接する被保持部３９が設けられているため、対向する第１ガイド部材２４間を通過することはできず、第１ガイド部材２４と押圧部２３材とで挟持されることで保持される。一方、操作部３５の被係止部３８は、第１ガイド部材２４の第１係止部２７に外側から係合している。このため、差込部３２は上下方向の移動が阻止され、取付バネ３１が保持部２１に固定される。   In the state where the insertion portion 32 is inserted into the holding portion 21, the insertion portion main body 36 is provided with the held portion 39 that comes into contact with the guide surface 26 of the first guide member 24.

On the other hand, the locked portion 38 of the operation portion 35 is engaged with the first locking portion 27 of the first guide member 24 from the outside. For this reason, the insertion part 32 is prevented from moving in the vertical direction, and the attachment spring 31 is fixed to the holding part 21.

次に、取付壁部Ｃが薄い場合（例えば、５ｍｍ）と厚い場合（例えば、２５ｍｍ）における埋込型照明器具１００の取り付けと、取付壁部Ｃの厚さに応じた取付バネ３１の固定位置の調整について、図４から図８に沿って説明する。   Next, when the mounting wall portion C is thin (for example, 5 mm) and thick (for example, 25 mm), the mounting of the embedded lighting device 100 and the fixing position of the mounting spring 31 according to the thickness of the mounting wall portion C The adjustment will be described with reference to FIGS.

まず、図４は、器具本体１１に対して取付バネ３１を取り付けた状態であり、取付壁部Ｃに埋込型照明器具１００を取り付ける前の状態である。取付バネ３１の固定位置は、薄い取付壁部Ｃに対応した固定位置であり、操作部３５の被係止部３８を第１ガイド部材２４の第１係止部２７に係合させている。   First, FIG. 4 shows a state in which the attachment spring 31 is attached to the appliance main body 11 and shows a state before the embedded lighting fixture 100 is attached to the attachment wall C. The fixing position of the mounting spring 31 is a fixing position corresponding to the thin mounting wall C, and the locked portion 38 of the operating portion 35 is engaged with the first locking portion 27 of the first guide member 24.

図５は、埋込型照明器具１００を薄い取付壁部Ｃに取り付けた状態を示している。取付バネ３１は広く拡開しており、取付バネ３１が更に拡開しようとする弾性的な付勢力が取付壁部Ｃの取付穴Ｈの縁部に下向きに作用する。このため器具本体１１には上方に引き上げられる力が作用し、フランジ１３が取付壁部Ｃの下面に圧接した状態となって、埋込型照明器具１００が取付壁部Ｃに設置される。このように、取付バネ３１が広く拡開していると取付バネ３１の取付力は大きくなる。   FIG. 5 shows a state in which the embedded luminaire 100 is attached to a thin attachment wall C. The mounting spring 31 is widened widely, and an elastic biasing force that the mounting spring 31 tries to further spread acts downward on the edge of the mounting hole H of the mounting wall C. For this reason, an upward pulling force is applied to the fixture body 11, and the flange 13 is in pressure contact with the lower surface of the mounting wall portion C, so that the embedded lighting fixture 100 is installed on the mounting wall portion C. Thus, when the attachment spring 31 is widely expanded, the attachment force of the attachment spring 31 is increased.

次に、取付バネ３１の固定位置を厚い取付壁部Ｃに対応した固定位置に変更する場合について説明する。取付バネ３１の固定位置の変更は、まず、図６に示すように、第１ガイド部材２４の第１係止部２７と差込部３２の被係止部３８との係合を解除する。前述のように、被保持部３９を除いた差込部主体３６と接続部３７の横幅は、対向して設けられる第１ガイド部材２４間の間隔より狭く形成され、第１ガイド部材２４間を通過可能に設定されている。このため、操作部３５の上端を手指等で外側に引くと、第１ガイド部材２４のガイド面２６に当接する被保持部３９より上方の部分、すなわち、差込部主体３６のうち被保持部３９より上方の部分と接続部３７とが、第１ガイド部材２４間を通過して外側に移動し、操作部３５も外側に移動する。これにより第１ガイド部材２４の第１係止部２７と差込部３２の被係止部３８との係合を解除することができる。第１ガイド部材２４の第１係止部２７と差込部３２の被係止部３８との係合を解除した状態のまま、取付バネ３１を上方に移動させる。   Next, a case where the fixing position of the mounting spring 31 is changed to a fixing position corresponding to the thick mounting wall portion C will be described. To change the fixing position of the attachment spring 31, first, as shown in FIG. 6, the engagement between the first locking portion 27 of the first guide member 24 and the locked portion 38 of the insertion portion 32 is released. As described above, the lateral width of the insertion portion main body 36 and the connection portion 37 excluding the held portion 39 is formed to be narrower than the interval between the first guide members 24 that are provided to face each other, and between the first guide members 24. It is set to pass. For this reason, when the upper end of the operation unit 35 is pulled outward with a finger or the like, the portion above the held portion 39 that contacts the guide surface 26 of the first guide member 24, that is, the held portion of the insertion portion main body 36. The portion above 39 and the connecting portion 37 pass between the first guide members 24 and move outward, and the operation portion 35 also moves outward. Thereby, the engagement between the first locking portion 27 of the first guide member 24 and the locked portion 38 of the insertion portion 32 can be released. The attachment spring 31 is moved upward while the engagement between the first locking portion 27 of the first guide member 24 and the locked portion 38 of the insertion portion 32 is released.

取付バネ３１を上方に移動させ、差込部３２の被係止部３８と第１ガイド部材２４の第２係止部２８とが対向する位置となったところで、操作部３５の上端を戻すことにより、図７に示すように、第１ガイド部材２４の第２係止部２８と差込部３２の被係止部３８とが係合し、この位置で取付バネ３１が保持部２１に固定される。   The mounting spring 31 is moved upward, and the upper end of the operation portion 35 is returned when the locked portion 38 of the insertion portion 32 and the second locking portion 28 of the first guide member 24 are opposed to each other. 7, the second locking portion 28 of the first guide member 24 and the locked portion 38 of the insertion portion 32 are engaged, and the mounting spring 31 is fixed to the holding portion 21 at this position. Is done.

図８の実線で示した取付バネ３１は、取付バネ３１の固定位置を厚い取付壁部Ｃに対応した固定位置にした状態で、埋込型照明器具１００を厚い取付壁部Ｃに取り付けた状態を示しており、２点鎖線で示した取付バネ３１は、取付バネ３１の固定位置を薄い取付壁部Ｃに対応した固定位置にした状態のままで、埋込型照明器具１００を厚い取付壁部Ｃに取り付けた状態を示している。   The attachment spring 31 shown by the solid line in FIG. 8 is a state in which the embedded lighting fixture 100 is attached to the thick attachment wall portion C in a state where the attachment position of the attachment spring 31 is a fixation position corresponding to the thick attachment wall portion C. The attachment spring 31 indicated by a two-dot chain line indicates that the embedded lighting device 100 is made a thick attachment wall while the attachment position of the attachment spring 31 is kept at the fixation position corresponding to the thin attachment wall portion C. The state attached to the part C is shown.

図８の実線で示す取付バネ３１は、２点鎖線で示した取付バネ３１よりも広く拡開しており、取付バネ３１の固定位置を厚い取付壁部Ｃに対応した固定位置にした場合のほうが、取付バネ３１の固定位置を薄い取付壁部Ｃに対応した固定位置にした場合よりも取付バネ３１の取付力は大きい。   The mounting spring 31 shown by the solid line in FIG. 8 is wider than the mounting spring 31 shown by the two-dot chain line, and the fixing position of the mounting spring 31 is the fixing position corresponding to the thick mounting wall C. The attachment force of the attachment spring 31 is larger than when the attachment position of the attachment spring 31 is set to the fixation position corresponding to the thin attachment wall portion C.

以上説明した実施例１に係る埋込型照明器具１００によれば、次のような効果を有する。   The embedded lighting fixture 100 according to the first embodiment described above has the following effects.
