Description

【０００１】
【発明の属する利用分野】
本発明は埋め込み型照明器具に関する。
【０００２】
【従来の技術】
本発明に係る従来例の模式的な側面図を図１３に示す。
【０００３】
この埋め込み型照明器具は、取付面（例えば天井面）１１に設けた埋め込み孔に挿入され、下部に設けられた外鍔部２１を埋め込み孔の周りの取付下面に当接させて取付けられる器具本体１と、可撓性を有する２つの取付バネ２、２とを備えてなる。この取付バネ２は、取付バネ２の下端部が器具本体１の外周下部に固定され、取付バネ２の上端部が器具本体１の側面に設けた係止用溝２２に上方側から係止することにより、上端部と下端部との間に湾曲部が器具本体１の外方へ向かって形成される。前記湾曲部は、天井面１１に設けた埋め込み孔に入れる際に、埋め込み孔の周面に当接して器具本体１の内方に向かって押圧され、これにより、取付バネ２の上端部が上方に押し上げられ、取付バネ２が係止用溝２２から外れる。係止用溝２２から外れたあとは、前記湾曲部を形成していた取付バネ２が元の直線状に戻り、天井面１１の裏面を押圧する。この押圧力によって器具本体１を天井面１１に取り付けることができる。図１３中、３は光源に電力を供給するための安定器、１２は本体フレームを示す。特開平８−１２４４１９号公報などにも同様のものが開示されている。
【０００４】
【発明が解決しようとする課題】
しかし、上記従来例に示す様な照明器具では、以下に示す様な第１の問題点が生じてしまう。
【０００５】
図１３に示す様な薄い天井面１１に施工する場合、図１３に示すように、器具本体１を斜めの姿勢にして埋め込み孔に挿入しようとすると、天井面１１を斜めにしたときに天井面１１に近くなる側に形成された前記湾曲部は、埋め込み孔の周面に当接しない場合が生じてしまい、その為、取付バネ２の上端部が係止用溝２２から外れなくなってしまい、該器具の天井面１１への取付けが不完全になってしまう。
【０００６】
また、以下に示す様な第２の問題点が生じてしまう。
天井面１１の厚さが厚くなると、天井面１１に設けた埋め込み孔の周面によって取付バネ２が器具本体１側に押圧されることになり、例えば取付バネ２が垂直状に近い状態になり、前記周面から下方向に滑り易くなってしまう。その為、照明器具が自身の重量によって下方側にずれる恐れが大きくなってしまう。
【０００７】
また、以下に示す様な第３の問題点が生じてしまう。
取付バネ２の上端部と下端部との間に外方へ向かって形成された前記湾曲部は、外鍔部２１よりも上側（取付け方向側）にあるため、例えば、該器具輸送時などに生じる強い振動などにより、該湾曲部に圧力がかかることがあり、その圧力により取付バネ２が器具本体１側に押圧されてしまい、該器具の施工前に取付バネ２の係止状態が解除されてしまう。
【０００８】
本発明は前記記全ての問題点に鑑みてなされたもので、その目的とするところは、天井面（特に、埋め込み孔の周面）を構成する天井材の薄さや厚さにも対応して施工可能で、該器具の輸送時などの生じる強い振動に対しては、取付バネの係止状態が保持可能な埋め込み型照明器具を提供することである。

【００１１】
請求項３記載の発明によれば、請求項１または請求項２に記載の埋め込み型照明器具において、取付バネには離脱用凹部が設けられ、取付バネ係止バネには、この離脱用凹部と相対する位置に離脱用凸部が設けられ、離脱用凹部に離脱用凸部を係合することにより、取付バネの接近する部位に、取付バネを係止しつつ取付バネを器具本体に近接させた位置に維持することを特徴とする。
【００１２】
請求項４記載の発明によれば、請求項３記載の埋め込み型照明器具において、離脱用凹部は、取付バネの係止状態で、器具本体側に曲率をもって曲げるように構成したことを特徴とする。
【００１３】
請求項５記載の発明によれば、請求項１乃至請求項３のいずれかに記載の埋め込み型照明器具において、取付バネ係止バネは２つの弾性片を有するものであることを特徴とする。
【００１４】
請求項６記載の発明によれば、請求項５記載の埋め込み型照明器具において、２つの弾性片の先端部の各々を連結部で連結したことを特徴とする。
【００１５】
請求項７記載の発明によれば、請求項１または請求項２に記載の埋め込み型照明器具において、取付バネは、略長方形状の切り欠き部を設け、取付バネ係止バネを切り欠き部に挿入することにより、取付バネの接近する部位に、取付バネを係止しつつ取付バネを器具本体に近接させた位置に維持することを特徴とする。
【００１６】
【実施の形態】
（実施の形態１）
本発明に係る第１の実施の形態の模式的な側面図を図１に、本実施の形態に用いる取付バネ２の斜視図を図２に示す。
【００１７】
図１３に示した従来例と異なる点は、器具本体１の取付構造であり、その他の従来例と同一構成には同一符号を付すことにより説明を省略する。
【００１８】
器具本体１の取付構造は、器具本体１の側面に設けられた取付部２３に取付バネ２を固定するための固定部９と、固定部９の下端に連接して設けられ、且つ、その上端部を外方へ弾性的に突出するように設けられ、外方へ広がる力により器具本体１を相対的に押し上げる取付バネ２と、取付バネ２の接近する部位で取付バネ２を係止しつつ、取付バネ２を器具本体１に近接させた位置に維持するとともに、この係止状態で取付バネ２より外方へ突出し、器具本体１の埋め込み孔への挿入時に、埋め込み孔の周面に当接して取付バネ２を係止状態から解除する取付バネ係止バネ８とからなる。また、取付バネ２は、その略中央部近傍に離脱用凹部７が設けられている。この離脱用凹部７と相対する位置であって取付バネ係止バネ８の略端部には離脱用凸部６が設けられている。そして、離脱用凹部７に離脱用凸部６を係合することにより、取付バネ２は器具本体１の側面近傍で係止状態になる。
【００１９】
以上のように、取付バネ２の係止状態において、取付バネ係止バネ８が、器具本体１の外鍔部２１近傍にて取付バネ２より外方へ突出しているので、天井面１１を構成する天井材が薄い場合に、図１にも示すように器具本体１を埋め込み孔へと斜めに挿入されても、図３に示すように、天井面１１に設けた埋め込み孔の周面に取付バネ係止バネ８が確実に当接するので、図２に示すように、取付バネ２の係止状態が確実に解除することができる。
【００２０】
また、天井面１１を構成する天井材が厚い場合には、上述のように、取付バネ２が垂直状に近い状態になってしまうので、取付バネ２による器具本体１の押し上げ力が低下するが、取付バネ係止バネ８が、天井面１１に設けた埋め込み孔の周面を押すために、器具本体１の取付保持力を補うことができる。（図４参照）また、取付バネ２の係止状態において、取付バネ係止バネ８が、器具本体１の外鍔部２１近傍にて取付バネ２より外方へ突出し、取付バネ係止バネ８より外鍔部２１の周縁の方が突出しているので、例えば該器具輸送時などに生じる強い振動などが生じても、取付バネ２の係止機構に圧力がかかりにくく、該器具の施工前に取付バネ２の係止状態が解除されてしまう、という不都合を低減できる。（図３参照）
（実施の形態２）
本発明に係る第２の実施の形態の斜視図を図５に示す。
【００２１】
図２に示した第１の実施の形態と異なる点は、取付バネ係止バネ８の２つの弾性片の先端部の各々を連結部１３で連結したことであり、その他の第１の実施の形態と同一構成には同一符号を付すことにより説明を省略する。
【００２２】
以上のように構成することにより、一方の該弾性片が係止解除の動作を始めると同時に、連結部１３を介して他方の該弾性片も連動するので、より確実に、取付バネ２の係止状態が解除できる。
【００２３】
（実施の形態３）
本発明に係る第３の実施の形態の斜視図を図６に示す。
【００２４】
図２に示した第１の実施の形態と異なる点は、取付バネ２に設けた離脱用凹部７の形状を、取付バネ２の係止状態において、器具本体１側に曲率をもって曲げるように構成したことであり、その他の第１の実施の形態と同一構成には同一符号を付すことにより説明を省略する。
【００２５】
以上のように構成することにより、器具本体１の取り外しを行う場合、図７に示すように、天井面１１に設けた埋め込み孔の周面の縁部に離脱用凹部７が食い込むことを防止できるので、スムーズな器具本体１の取り外し作業が実現できる。なお、本実施の形態に示したような構成を有していない場合には、図８に示すように、天井面１１に設けた埋め込み孔の周面の縁部に離脱用凹部７が食い込んでしまい、器具本体１の取り外し作業が困難になったり、天井面１１の破損が生じたりしてしまう。
【００２６】
（実施の形態４）
本発明に係る第４の実施の形態の斜視図を図９に示す。
【００２７】
図２に示した第１の実施の形態と異なる点は、取付バネ２の下方に略長方形状の切り欠き部１４を設け、固定部９に一端が連結した取付バネ係止バネ８を構成する、略上方へ向って曲折した弾性片１５を、該切り欠き部１４に挿入することにより、取付バネ２の係止状態となるように構成したことであり、その他の第１の実施の形態と同一構成には同一符号を付すことにより説明を省略する。
【００２８】
なお、図９では、弾性片１５は略上方へ向って曲折するように構成したが、図１０に示すように、弾性片１５は略下方に向って曲折するように構成しても構わない。
【００２９】
（実施の形態５）
本発明に係る第５の実施の形態の斜視図を図１１に示す。
【００３０】
図２に示した第１の実施の形態と異なる点は、図２に示す構成では、取付バネ係止バネ８を固定部９の上端部から下方へ向って曲折するように構成したが、本実施の形態では、取付バネ係止バネ８の一端を固定部９に連結し、略上方へ向って曲折するように構成したことであり、その他の第１の実施の形態と同一構成には同一符号を付すことにより説明を省略する。
【００３１】
（実施の形態６）
本発明に係る第６の実施の形態の斜視図を図１２に示す。
【００３２】
図１１に示した第５の実施の形態と異なる点は、取付バネ係止バネ８の２つの弾性片の先端部の各々を連結部１７で連結したことであり、その他の第５の実施の形態と同一構成には同一符号を付すことにより説明を省略する。
【００３３】
以上のように構成することにより、一方の該弾性片が係止解除の動作を始めると同時に、連結部１７を介して他方の該弾性片も連動するので、より確実に、取付バネ２の係止状態が解除できる。

BACKGROUND OF THE INVENTION
The present invention relates to an embedded lighting fixture.
[0002]
[Prior art]
FIG. 13 shows a schematic side view of a conventional example according to the present invention.
[0003]
This embedded luminaire is inserted into an embedded hole provided on an attachment surface (for example, a ceiling surface) 11 and is attached by contacting an outer flange portion 21 provided at a lower portion with an attachment lower surface around the embedded hole. 1 and two attachment springs 2 and 2 having flexibility. The attachment spring 2 has a lower end portion of the attachment spring 2 fixed to the lower part of the outer periphery of the instrument body 1, and an upper end portion of the attachment spring 2 is engaged with a locking groove 22 provided on the side surface of the instrument body 1 from above. Thus, a curved portion is formed between the upper end portion and the lower end portion toward the outside of the instrument body 1. When the bending portion is inserted into the embedding hole provided in the ceiling surface 11, the bending portion abuts on the peripheral surface of the embedding hole and is pressed toward the inside of the instrument body 1, whereby the upper end portion of the mounting spring 2 is moved upward. The attachment spring 2 is released from the locking groove 22. After detaching from the locking groove 22, the mounting spring 2 forming the curved portion returns to the original linear shape and presses the back surface of the ceiling surface 11. The instrument body 1 can be attached to the ceiling surface 11 by this pressing force. In FIG. 13, 3 is a ballast for supplying power to the light source, and 12 is a main body frame. A similar one is also disclosed in Japanese Patent Laid-Open No. 8-124419.
[0004]
[Problems to be solved by the invention]
However, the lighting apparatus as shown in the conventional example has the following first problem.
[0005]
When constructing on a thin ceiling surface 11 as shown in FIG. 13, as shown in FIG. 13, when trying to insert the instrument main body 1 into an embedding hole in an oblique posture, the ceiling surface 11 is inclined when the ceiling surface 11 is inclined. The curved portion formed on the side close to 11 may not contact the peripheral surface of the embedding hole, so that the upper end of the mounting spring 2 cannot be removed from the locking groove 22. Installation of the appliance on the ceiling surface 11 will be incomplete.
[0006]
In addition, the following second problem occurs.
When the thickness of the ceiling surface 11 is increased, the mounting spring 2 is pressed toward the instrument body 1 by the peripheral surface of the embedding hole provided in the ceiling surface 11. For example, the mounting spring 2 is in a state of being nearly vertical. It becomes easy to slip downward from the peripheral surface. For this reason, there is a greater risk that the lighting fixture will shift downward due to its own weight.
[0007]
In addition, the third problem as described below occurs.
Since the curved portion formed outwardly between the upper end portion and the lower end portion of the mounting spring 2 is on the upper side (the mounting direction side) of the outer flange portion 21, for example, when the instrument is transported Due to the strong vibration that occurs, pressure may be applied to the curved portion, and the attachment spring 2 is pressed toward the instrument body 1 by the pressure, and the engagement state of the attachment spring 2 is released before the instrument is constructed. End up.
[0008]
The present invention has been made in view of all the above-mentioned problems, and its object is to cope with the thinness and thickness of the ceiling material constituting the ceiling surface (particularly, the peripheral surface of the embedded hole). An object of the present invention is to provide an embedded lighting device that can be applied and can maintain the locking state of the mounting spring against strong vibrations that occur during transportation of the device.
[0009]
[Means for Solving the Problems]
In order to solve the above problems, according to the invention described in claim 1, the outer flange portion provided in the lower portion is inserted into the embedded hole provided in the mounting surface, and the mounting lower surface around the embedded hole is brought into contact with the mounting lower surface. The mounting spring includes: a mounting body including a mounting body, and a plurality of mounting springs that are fixed to the lower peripheral portion of the mounting body in the vicinity of the lower end and are elastically protruded from the upper end. The mounting spring is held at a position close to the instrument body while the mounting spring is locked to the approaching portion of the mounting hole, and protrudes outward from the mounting spring in this locked state. An attachment spring locking spring is provided to contact the peripheral surface of the mounting spring and release the mounting spring from the locked state.
[0010]
According to a second aspect of the present invention, in the embedded luminaire according to the first aspect, the attachment spring locking spring is engaged with a lower portion of the attachment spring.
[0011]
According to a third aspect of the present invention, in the embedded luminaire according to the first or second aspect, the mounting spring is provided with a detaching recess, and the mounting spring locking spring includes the detaching recess. A detaching projection is provided at the opposite position, and by engaging the detaching projection with the detaching recess, the mounting spring is brought close to the instrument body while the mounting spring is locked to the approaching portion of the mounting spring. It is characterized in that it is maintained in a closed position.
[0012]
According to a fourth aspect of the present invention, in the embedded lighting device according to the third aspect, the recess for detachment is configured to bend with a curvature toward the main body of the device in a state where the mounting spring is locked. .
[0013]
According to a fifth aspect of the present invention, in the embedded luminaire according to any one of the first to third aspects, the mounting spring locking spring has two elastic pieces.
[0014]
According to the invention described in claim 6, in the embedded luminaire described in claim 5, each of the tip portions of the two elastic pieces is connected by the connecting portion.
[0015]
According to the seventh aspect of the present invention, in the embedded luminaire according to the first or second aspect, the attachment spring is provided with a substantially rectangular cutout portion, and the attachment spring locking spring is provided in the cutout portion. By inserting, the attachment spring is held at a position close to the instrument main body while the attachment spring is locked to a portion where the attachment spring approaches.
[0016]
Embodiment
(Embodiment 1)
A schematic side view of the first embodiment according to the present invention is shown in FIG. 1, and a perspective view of an attachment spring 2 used in this embodiment is shown in FIG.
[0017]
The difference from the conventional example shown in FIG. 13 is the mounting structure of the instrument body 1, and the same components as those of the other conventional examples are denoted by the same reference numerals and the description thereof is omitted.
[0018]
The attachment structure of the instrument body 1 is provided with a fixing part 9 for fixing the attachment spring 2 to the attachment part 23 provided on the side surface of the instrument body 1, and connected to the lower end of the fixing part 9. The mounting spring 2 is provided so as to protrude elastically outward, and pushes up the instrument body 1 relatively by the force spreading outward, and the mounting spring 2 is locked at a position where the mounting spring 2 approaches. The mounting spring 2 is maintained at a position close to the instrument main body 1 and protrudes outward from the mounting spring 2 in this locked state. When the instrument spring 1 is inserted into the embedding hole, the mounting spring 2 contacts the peripheral surface of the embedding hole. It comprises an attachment spring locking spring 8 that contacts and releases the mounting spring 2 from the locked state. Further, the attachment spring 2 is provided with a detachment recess 7 in the vicinity of the substantially central portion thereof. A detaching convex portion 6 is provided at a position opposite to the detaching concave portion 7 and at a substantially end portion of the mounting spring locking spring 8. Then, by engaging the release protrusion 6 with the release recess 7, the attachment spring 2 is locked in the vicinity of the side surface of the instrument body 1.
[0019]
As described above, when the mounting spring 2 is locked, the mounting spring locking spring 8 protrudes outward from the mounting spring 2 in the vicinity of the outer flange portion 21 of the instrument body 1. When the ceiling material is thin, even if the instrument body 1 is inserted obliquely into the embedding hole as shown in FIG. 1, it is attached to the peripheral surface of the embedding hole provided on the ceiling surface 11 as shown in FIG. Since the spring locking spring 8 comes into contact with certainty, the locking state of the attachment spring 2 can be reliably released as shown in FIG.
[0020]
Moreover, when the ceiling material which comprises the ceiling surface 11 is thick, as mentioned above, since the attachment spring 2 will be in the state near perpendicular | vertical shape, although the pushing-up force of the instrument main body 1 by the attachment spring 2 falls, it is. Since the mounting spring locking spring 8 presses the peripheral surface of the embedded hole provided in the ceiling surface 11, the mounting holding force of the instrument body 1 can be supplemented. (See FIG. 4) In addition, in a state where the mounting spring 2 is locked, the mounting spring locking spring 8 protrudes outward from the mounting spring 2 in the vicinity of the outer flange portion 21 of the instrument body 1, and the mounting spring locking spring 8. Since the outer periphery of the outer flange portion 21 protrudes more, for example, even if a strong vibration or the like that occurs during transportation of the instrument occurs, it is difficult for pressure to be applied to the locking mechanism of the mounting spring 2 and before the instrument is constructed. The inconvenience that the locking state of the mounting spring 2 is released can be reduced. (See Figure 3)
(Embodiment 2)
FIG. 5 shows a perspective view of the second embodiment according to the present invention.
[0021]
The difference from the first embodiment shown in FIG. 2 is that each of the tip ends of the two elastic pieces of the mounting spring locking spring 8 is connected by the connecting portion 13, and the other first embodiments are the same. The same components as those in the embodiment are given the same reference numerals and the description thereof is omitted.
[0022]
By configuring as described above, one elastic piece starts the unlocking operation, and at the same time, the other elastic piece is also interlocked via the connecting portion 13, so that the engagement of the mounting spring 2 is more reliably performed. The stop state can be released.
[0023]
(Embodiment 3)
FIG. 6 shows a perspective view of a third embodiment according to the present invention.
[0024]
2 is different from the first embodiment shown in FIG. 2 in that the shape of the detachable recess 7 provided in the mounting spring 2 is bent with a curvature toward the instrument body 1 when the mounting spring 2 is locked. Therefore, the same components as those of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.
[0025]
With the configuration as described above, when the instrument body 1 is removed, as shown in FIG. 7, the separation recess 7 can be prevented from biting into the edge of the peripheral surface of the embedding hole provided in the ceiling surface 11. Therefore, a smooth removal operation of the instrument body 1 can be realized. In the case where the configuration as shown in the present embodiment is not provided, as shown in FIG. 8, the separation recess 7 bites into the edge of the peripheral surface of the embedding hole provided in the ceiling surface 11. As a result, it becomes difficult to remove the instrument body 1 or the ceiling surface 11 is damaged.
[0026]
(Embodiment 4)
FIG. 9 shows a perspective view of the fourth embodiment according to the present invention.
[0027]
A difference from the first embodiment shown in FIG. 2 is that a mounting spring locking spring 8 is provided in which a substantially rectangular cutout portion 14 is provided below the mounting spring 2 and one end is connected to the fixing portion 9. The elastic piece 15 bent substantially upward is inserted into the cutout portion 14 so that the mounting spring 2 is locked, and the other first embodiment is the same as that of the first embodiment. The same reference numerals are assigned to the same components, and the description is omitted.
[0028]
In FIG. 9, the elastic piece 15 is configured to bend substantially upward, but as illustrated in FIG. 10, the elastic piece 15 may be configured to bend substantially downward.
[0029]
(Embodiment 5)
FIG. 11 shows a perspective view of the fifth embodiment according to the present invention.
[0030]
The difference from the first embodiment shown in FIG. 2 is that the mounting spring locking spring 8 is bent downward from the upper end portion of the fixing portion 9 in the configuration shown in FIG. In the embodiment, one end of the mounting spring locking spring 8 is connected to the fixing portion 9 and is bent substantially upward, and the same configuration as that of the other first embodiment is the same. The description will be omitted by attaching the reference numerals.
[0031]
(Embodiment 6)
FIG. 12 shows a perspective view of the sixth embodiment according to the present invention.
[0032]
The difference from the fifth embodiment shown in FIG. 11 is that each of the tip ends of the two elastic pieces of the mounting spring locking spring 8 is connected by the connecting portion 17, and the other fifth embodiments are different. The same components as those in the embodiment are given the same reference numerals and the description thereof is omitted.
[0033]
By configuring as described above, one elastic piece starts the unlocking operation, and at the same time, the other elastic piece is also interlocked via the connecting portion 17, so that the engagement of the mounting spring 2 is more reliably performed. The stop state can be released.
[0034]
The embodiment according to the present invention is not limited to the above-described embodiment, and any combination of the above-described embodiments may be used as long as the effects of the present invention are achieved.
[0035]
