【発明の属する技術分野】
この発明は照明装置の取付構造に係り、特に、天井板に対する照明器具を内蔵した箱体の上下方向位置を容易に調整し得て、外観を損なわせる不都合を解消し得る照明装置の取付構造に関する。
【０００２】
【従来の技術】
照明装置には、天井板の上側に設けられるいわゆる埋め込み型のものがある。埋め込み型の照明装置には、天井スラブから吊り具により吊り下げて保持された支持部材に天井板を支持して設け、この天井板に開口を形成して設け、この開口を覆うように天井板の上側に下向きに開口する箱体を支持部材に取付けて設け、この箱体内に開口から光りを照射する照明器具を内蔵しているものがある。
【０００３】
この照明装置は、照明器具を内蔵した箱体を天井板の支持部材に取付けており、箱体はそのままに照明器具を交換することによって、配光を容易に変更することができるため、室内の雰囲気を容易に変化させることができる。
【０００４】
従来の照明装置の取付構造には、枠体と上天井板とで下方に開口する箱状の埋め込み部材を形成し、この埋め込み部材の枠体の内周に沿って間接照明器具を装着するとともに上天井板に直接照明器具を装着し、天井板に形成した開口に埋め込み部材を下側から埋め込んで天井板の支持部材である下地材に取付け、間接照明器具の内周側を覆うじゃま板を枠体の全周にわたって取付けたものがある（例えば、特許文献１参照。）。

【０００６】
【発明が解決しようとする課題】
ところで、従来の照明装置の取付構造においては、天井板に形成した開口の上側に照明器具を内蔵した箱体を取付ける場合に、箱体を天井板の支持部材や下地材に取付具により取付けている。
【０００７】
ところが、従来の取付構造においては、天井板に対する箱体の上下方向位置を調整することができないため、天井板に対する箱体の上下方向位置がずれてしまい、箱体下端の下側面と天井板の下側面との間に段差を生じる問題がある。
【０００８】
例えば、天井板に形成した開口内に箱体下端を挿入位置させて取付けた場合には、天井板に対する箱体の上下方向位置のずれに起因して、箱体下端の下側面と天井板の下側面とを同一高さに揃えることができず、段差を生じる問題がある。
【０００９】
このため、従来の照明装置の取付構造においては、箱体の取付時に段差を無くすための高さ調整作業に手間がかかり、取付作業が煩雑化する不都合があるとともに、箱体下端の下側面と天井板の下側面とに段差を生じた場合に、外観を損なわせる不都合がある。
【００１０】
【課題を解決するための手段】
そこで、この発明は、上述不都合を除去するために、天井スラブから吊り具により吊り下げて保持された支持部材に天井板を支持して設け、この天井板に開口を形成して設け、この開口を覆うように天井板の上側に下向きに開口する箱体を前記支持部材に取付けて設け、この箱体内に前記開口から光を照射する照明器具を内蔵した照明装置において、前記天井板の開口内に挿入位置された前記箱体下端の下側面を前記天井板の下側面に一致させるように前記天井板に対する箱体の上下方向位置を調整可能な取付具を設けたことを特徴とする。
【００１１】
【発明の実施の形態】
この発明の照明装置の取付構造は、天井板の開口内に挿入位置された箱体下端の下側面を天井板の下側面に一致させるように、天井板に対する箱体の上下方向位置を調整可能な取付具を設けたことにより、取付具によって天井板に対する照明器具を内蔵した箱体の上下方向位置を調整しながら箱体を支持部材に取付けることができる。

【００３２】
これにより、箱体２４は、天井板１２に対する箱体２４の上下方向位置を調整可能な取付具３６によって、天井板１２に対する上下方向位置を調整しながら第１の支持部材１０−１に取付けられる。
【００３３】
このように、この照明装置２０の取付構造は、天井板１２の開口２２内に挿入位置された箱体２４下端を構成する箱体側取付体３８の平行部５４の下側面８６を天井板１２の下側面５２に一致させるように、天井板１２に対する箱体２４の上下方向位置を調整可能な取付具３６を設けたことにより、取付具３６によって天井板１２に対する照明器具２６を内蔵した箱体２４の上下方向位置を調整しながら、箱体２４を第１の支持部材１０−１に取付けることができる。

BACKGROUND OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device mounting structure, and more particularly, to a lighting device mounting structure that can easily adjust the vertical position of a box with a built-in lighting fixture with respect to a ceiling panel and can eliminate the disadvantage of damaging the appearance. .
[0002]
[Prior art]
There is a so-called embedded type lighting device provided on the upper side of the ceiling board. In the embedded lighting device, a ceiling plate is supported by a support member that is suspended and held from a ceiling slab by a hanging tool, an opening is formed in the ceiling plate, and the ceiling plate is provided so as to cover the opening. In some cases, a box that opens downward is attached to a support member, and a lighting fixture that irradiates light from the opening is built in the box.
[0003]
In this lighting device, a box with a built-in lighting fixture is attached to the support member of the ceiling plate, and the light distribution can be easily changed by replacing the lighting fixture with the box intact. The atmosphere can be easily changed.
[0004]
In a conventional lighting device mounting structure, a box-shaped embedded member that opens downward is formed by a frame and an upper ceiling plate, and an indirect lighting fixture is mounted along the inner periphery of the frame of the embedded member. Attach the lighting fixture directly to the upper ceiling plate, embed the embedded member into the opening formed in the ceiling plate from below, attach it to the base material that is the support member of the ceiling plate, and install the baffle plate that covers the inner peripheral side of the indirect lighting fixture There is what was attached over the perimeter of a frame (for example, refer to patent documents 1).
[0005]
[Patent Document 1]
JP-A-7-99008 (Claims, FIGS. 1 to 3)
[0006]
[Problems to be solved by the invention]
By the way, in the conventional mounting structure of a lighting device, when mounting a box with a built-in lighting fixture on the upper side of the opening formed in the ceiling plate, the box is attached to the support member or the base material of the ceiling plate with a fixture. Yes.
[0007]
However, in the conventional mounting structure, since the vertical position of the box relative to the ceiling plate cannot be adjusted, the vertical position of the box relative to the ceiling plate is shifted, and the lower surface of the lower end of the box and the ceiling plate There is a problem that a step is formed between the lower surface and the lower surface.
[0008]
For example, when the lower end of the box is inserted into the opening formed in the ceiling plate and attached, due to the displacement of the vertical position of the box relative to the ceiling plate, the lower side of the lower end of the box and the ceiling plate There is a problem that the lower surface cannot be aligned at the same height and a step is generated.
[0009]
For this reason, in the conventional lighting device mounting structure, it takes time to adjust the height to eliminate the step when mounting the box, and the mounting work becomes inconvenient, and the lower side of the lower end of the box and When a step is generated on the lower surface of the ceiling plate, there is a disadvantage that the appearance is impaired.
[0010]
[Means for Solving the Problems]
Therefore, in order to eliminate the inconvenience described above, the present invention provides a support member that is supported by being suspended from a ceiling slab by a suspension tool, and provided with an opening formed in the ceiling plate. A box that opens downward on the upper side of the ceiling plate so as to cover the ceiling plate is provided on the support member, and a lighting device that irradiates light from the opening in the box is built in the opening of the ceiling plate. An attachment is provided that can adjust the vertical position of the box relative to the ceiling plate so that the lower surface of the lower end of the box that is inserted into the box coincides with the lower surface of the ceiling plate.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
The mounting structure of the lighting device of the present invention can adjust the vertical position of the box relative to the ceiling plate so that the lower side of the lower end of the box inserted into the opening of the ceiling plate matches the lower side of the ceiling plate. By providing such a fixture, the box can be attached to the support member while adjusting the vertical position of the box containing the lighting fixture with respect to the ceiling plate by the fixture.
[0012]
