Description

【0001】
【発明の属する技術分野】
本発明は車両、特にバスの車室内の天井に取付けられる照明装置の取付構造に関するものである。
【0002】
【従来の技術】
この種の照明装置の取付構造として、図4に示すように、車両のルーフパネル1の下面に車両の進行方向に延びる複数の縦骨2a,2aと車幅方向に延びる複数の横骨2bが格子状に設けられ、縦骨2a,2aと横骨2bの間に板状のインシュレータ3を挿入した後、蛍光灯4を収納しかつ保持するケース5がその開口部を下向きにして挿入され、ケース5の開口部の周縁に設けられたフランジ5a,5aがブラケット6,6を介して縦骨2a,2a又は横骨2bに取付られるように構成されたものが知られている。
【0003】
具体的に、フランジ5a,5aは縦骨2a,2aに平行に形成され、ブラケット6,6は縦骨2a,2a又は横骨2bの下面に車両の進行方向に延びて固着される。ブラケット6,6はケース5のフランジ5a,5aに対向して水平に延びるように構成され、ブラケット6,6にはグロメットスクリュー6b,6bが装着された透孔6a,6aが形成される。この透孔6a,6aに対向するフランジ5a,5aには長孔5b,5bが形成される。このように構成されたケース5のフランジ5a,5aの下面にはレール7,7がそれぞれ当てられ、レール7,7を介してタッピングスクリュー7a,7aをフランジ5a,5aの長孔5b,5bに挿通してグロメットスクリュー6b,6bに螺合することにより、ケース5は所定の固定位置に固定される。ケース5を固定した後には、蛍光灯4を取付け、ケース5の開口部にこの開口部を塞ぐようにグローブ8を取付け、その後グローブ8を固定し、レール7,7の下面にモール9,9を被せて係止する。
【0004】
【発明が解決しようとする課題】
しかし、上述した従来の取付構造では、格子状に設けられた複数の縦骨2a,2aの取付ピッチ又は複数の横骨2bの取付ピッチが変更された場合には、変更された縦骨2a,2a間又は横骨2b間の寸法に適合させた新たなケースを準備する必要があり、従来使用されていたケース5を使用できない不具合がある。特に、ケース5には、蛍光灯4の放電開始後の電流を一定に制限する安定器や、蛍光灯4の支持具4a等を装備する必要があるため、ケースの変更は比較的困難で、ケース種類の増大から照明装置の取付工数及び部品の管理工数が増大する問題点もある。この点を解消するために、縦骨2a,2a間又は横骨2b間の起りうる最小の寸法に適合させたケース5を使用し、比較的変更の容易なブラケット6,6の形状のみを変更して取付ピッチの異なる全ての車両に同一ケース5を使用することも考えられるが、比較的大型の車両に小型のケース5を使用することは、照明装置の車両の大きさに対する発光面積を縮小させ、車室内用照明装置としての機能を損う恐れがある。
本発明の目的は、同一ケースの使用を可能にして照明装置の取付工数及び管理工数を低減するとともに、照明装置としての機能を十分に発揮しうる車室内用照明装置の取付構造を提供することにある。
【0005】
【課題を解決するための手段】
請求項1に係る発明は、図1及び図3に示すように、車両10のルーフパネル11の下面に車両10の進行方向に延びる複数の縦骨12と車幅方向に延びる複数の横骨13が格子状に設けられ、縦骨12と横骨13の間に板状のインシュレータ16が挿入され、蛍光灯17を収納しかつ保持するケース18がインシュレータ16が挿入された縦骨12と横骨13の間にブラケット21を介して取付けられた車室内用照明装置の取付構造の改良である。
その特徴ある構成は、ブラケット21がインシュレータ16の下面を支持する水平片21aと水平片21aの端部に設けられ縦骨12又は横骨13に固定可能に構成された垂直片21b,21bとを有し、ケース18が水平片21aの下部に取付けられ、インシュレータ16は縦骨12と横骨13のなす大きさに相応して形成された板状の断熱材とその断熱材を被覆しかつ蛍光灯17の光を反射可能なフィルムとにより構成されたところにある。
【0006】
ケース18を水平片21aの下部に取付けることにより、縦骨12,12の取付ピッチの大小又は横骨13の取付ピッチの大小に拘らずケース18を所定の位置に固定し、比較的小型のケース18を使用することにより、縦骨12,12と横骨13の取付ピッチが変更された場合であっても同一のケース18の使用を可能にする。
インシュレータ16が蛍光灯17の光を反射可能なフィルムを備えることにより、比較的小型のケース18が縦骨12,12間又は横骨13間の寸法が比較的大きい大型の車両に使用された場合であっても、蛍光灯17から発せられた光をインシュレータ16が反射して車室内を有効に照明する。
【0007】
【発明の実施の形態】
次に本発明の実施の形態を図面に基づいて詳しく説明する。
図1〜図3に示すように、バス10のルーフパネル11の下面にはバス10の進行方向に延びる2本の縦骨12,12と、車幅方向に延びる複数の横骨13とが格子状に設けられる。縦骨12の横断面形状は略Z字状に形成され、横骨13の横断面形状は角筒状に形成される(図1、図2)。縦骨12と横骨13の間には照明装置14が挿入されて固定される。
【0008】
図1及び図2に示すように、照明装置14は、縦骨12と横骨13の間に挿入された板状のインシュレータ16と、蛍光灯17(図1)を収納しかつ保持するケース18とを備える。本発明のインシュレータ16はルーフパネル11からの熱を遮断する本来の断熱のためと、蛍光灯17の光を反射するために挿入される。そのため、インシュレータ16は蛍光灯17の光を反射可能に構成される。本実施の形態におけるインシュレータ16はポリエステルフェルトにより構成され、蛍光灯17の光を反射させるためにこのインシュレータ16の下面は難燃性の高いポリウレタンフィルムで被覆される。この光を反射可能に構成された板状のインシュレータ16は、縦骨12と横骨13のなす大きさに相応して形成され、縦骨12と横骨13の間に僅かな隙間を持って挿入可能に構成される。
【0009】
ケース18は鋼板を折曲げ加工することにより作られ、周囲に補強のための立上がり部18aが形成される。ケース18には蛍光灯17の両端を支持する一対の支持具19,19と、図示しないが、電源により点灯された蛍光灯17の放電開始後の電流を一定に制限する安定器が取付けられる。蛍光灯17は一対の支持具19,19により両端が支持されることによりケース18に収容される。このケース18は、インシュレータ16が挿入された縦骨12と横骨13の間にブラケット21を介して取付けられる。
【0010】
ブラケット21は水平片21aとこの水平片21aの端部に形成された垂直片21bとを有し、本実施の形態における垂直片21bは水平片21aの両端に下方に向って一対設けられる。このブラケット21の垂直片21bには縦骨12にネジ止めするための孔22が形成され、この孔22に対応する縦骨12には第1ネジ孔23が形成される(図1の一方の垂直片に示す)。水平片21aは垂直片21bが縦骨12に取付けられた状態でインシュレータ16の下面を支持するように水平に形成され、ケース18をこの水平片21aの下部に取付けるための第2ネジ孔24が形成される(図2)。
【0011】
なお、縦骨12近傍の横骨13の下部には取付孔13a(図1)が形成され、取付孔13aに対向するレール32,32には長孔32aが形成される。取付孔13a及び長孔32aにはリベット33が挿通可能に構成される。図1に示すように、レール32の下面にはその下方に4本のリブ32b〜32eが突設され、これらのリブ32b〜32eのうちの2本のリブ32b,32cにはレール32の下面を覆うモール34が係止する。残りの2本のリブ32d,32eのうち1本のリブ32dの下端にはクッション36を介して開口部を覆うグローブ37の側縁上面が当接し、残りの1本のリブ32eにはグローブ37の脱落防止用のストッパ38が係止する。また39は天井内板を示す。
【0012】
このように構成された車室内用照明装置の取付手順を説明する。
図1及び図2に示すように、照明装置14をバス10の天井に取付けるときには、先ずインシュレータ16を縦骨12及び横骨13の間に挿入し、続いて一対のブラケット21,21を挿入する。ブラケット21,21の挿入に際しては水平片21aがインシュレータ16の下面を支持するように水平に挿入し、この状態で垂直片21b,21bにそれぞれ形成された孔22を縦骨12に形成された第1ネジ孔23に一致させ、第1止めネジ27を孔22に遊挿して第1ネジ孔23に螺合する(図1)。
【0013】
次に、ブラケット21,21にケース18を取付ける。ケース18の取付けは、ケース18に形成された通孔18b(図2)をブラケット21の水平片21aに形成された第2ネジ孔24(図2)に一致させ、第2止めネジ28を通孔18bに遊挿して第2ネジ孔24に螺合することにより行い、これによりケース18が所定の位置に固定される。この状態でケース18内の図示しない電線やコネクタを電気的に接続させる。従って、比較的小型のケース18を使用することにより、格子状に設けられた縦骨12,12と横骨13の取付ピッチが変更されても、ブラケット21,21を変更することにより同一のケース18を所定の位置に固定することができる。
【0014】
次に、縦骨12,12に沿って一対のレール32,32をそれぞれ横骨13の下面に当て、レール32,32の長孔32aを横骨13に形成れた取付孔13aに一致させる。長孔32a及び取付孔13aが一致したならばリベット33をその長孔32a及び取付孔13aに挿通させ、取付孔13aから突出したリベット33の先端部分を押し広げることにより一対のレール32,32を縦骨12,12に沿ってそれぞれ横骨13に固定する。更に蛍光灯17の両端をケース18に設けられた一対の支持具19,19に取付け、ケース18の下部のレール32,32の間を塞ぐようにグローブ37を取付ける。その後、グローブ37をストッパ38で固定し、レール32の下面にモール34を被せて係止する。これにより一連の作業を終了させる。
【0015】
なお、上述した実施の形態では、インシュレータ16としてポリエステルフェルトを挙げたが、断熱作用を有するものであればこれに限らず、ウレタンやグラスウール等の断熱材であっても良い。
また、上述した実施の形態では、インシュレータ16の下面を難燃性の高いポリウレタンフィルムで被覆して蛍光灯17の光を反射するようにしたが、被覆するフィルムは蛍光灯17の光を反射可能であって難燃性の高いものであればアルミ箔等であっても良い。フィルムを装着する方法としてはインシュレータ16に巻付けた後に端部を接着テープで止めたり、或は接着剤を使用してフィルム全体をインシュレータ16の下面に接着しても良い。
更に、上述した実施の形態では、ブラケットを縦骨に固着したが、これに限らず横骨に固着してもよく、車両はバスではなく、トラック又はその他の車両でもよい。
【0016】
【発明の効果】
以上述べたように、本発明によれば、インシュレータを蛍光灯の光を反射可能に構成し、ブラケットがインシュレータの下面を支持する水平片と縦骨又は横骨に固定可能に構成された垂直片とを有し、ケースを水平片の下部に取付けたので、比較的小型のケースを使用することにより、縦骨の取付ピッチの大小又は横骨の取付ピッチの大小に拘らず同一のケースを所定の位置に固定することを可能にする。比較的小型のケースが縦骨間又は横骨間の寸法が比較的大きい大型の車両に使用された場合には、ケースから漏れ出る蛍光灯からの光をインシュレータが反射して車室内を有効に照明する。この結果、同一ケースの使用を可能にしてケースが変更されることに伴う照明装置の取付作業工数及び管理工数を低減させるとともに、車室内を照明する車室内用照明装置としての機能を十分に発揮させることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a mounting structure for a lighting device to be mounted on a ceiling of a vehicle, particularly a bus cabin.
[0002]
[Prior art]
As shown in FIG. 4, as a mounting structure of this type of lighting device, a plurality of vertical bones 2a, 2a extending in the vehicle traveling direction and a plurality of horizontal bones 2b extending in the vehicle width direction are provided on the lower surface of the roof panel 1 of the vehicle. After the plate-like insulator 3 is inserted between the vertical bones 2a, 2a and the horizontal bones 2b, a case 5 for storing and holding the fluorescent lamp 4 is inserted with its opening facing downward, It is known that flanges 5a, 5a provided at the periphery of the opening of the case 5 are attached to the longitudinal bones 2a, 2a or the transverse bones 2b via brackets 6, 6.
[0003]
Specifically, the flanges 5a and 5a are formed in parallel to the longitudinal bones 2a and 2a, and the brackets 6 and 6 are fixed to the lower surfaces of the longitudinal bones 2a and 2a or the lateral bones 2b in the traveling direction of the vehicle. The brackets 6 and 6 are configured to extend horizontally facing the flanges 5a and 5a of the case 5, and the brackets 6 and 6 are formed with through holes 6a and 6a to which grommet screws 6b and 6b are attached. Long holes 5b and 5b are formed in the flanges 5a and 5a facing the through holes 6a and 6a. Rails 7 are respectively applied to the lower surfaces of the flanges 5a and 5a of the case 5 configured as described above, and the tapping screws 7a and 7a are inserted into the long holes 5b and 5b of the flanges 5a and 5a via the rails 7 and 7, respectively. The case 5 is fixed at a predetermined fixing position by being inserted and screwed into the grommet screws 6b, 6b. After the case 5 is fixed, the fluorescent lamp 4 is attached, the globe 8 is attached to the opening of the case 5 so as to close the opening, the globe 8 is then fixed, and the moldings 9 and 9 are attached to the lower surfaces of the rails 7 and 7. Cover and lock.
[0004]
[Problems to be solved by the invention]
However, in the conventional mounting structure described above, when the mounting pitch of the plurality of vertical bones 2a, 2a provided in a lattice pattern or the mounting pitch of the plurality of horizontal bones 2b is changed, the changed vertical bones 2a, It is necessary to prepare a new case adapted to the dimension between 2a or the horizontal bone 2b, and there is a problem that the case 5 that has been used conventionally cannot be used. In particular, since it is necessary to equip the case 5 with a ballast for limiting the current after the start of the discharge of the fluorescent lamp 4 and the support 4a of the fluorescent lamp 4, etc., it is relatively difficult to change the case. There is also a problem that the man-hours for mounting the lighting device and the man-hours for managing the parts increase due to an increase in case types. In order to eliminate this point, only the shape of the brackets 6 and 6 that are relatively easy to change is used by using the case 5 that is adapted to the minimum dimension that can occur between the longitudinal bones 2a and 2a or between the transverse bones 2b. Although it is conceivable to use the same case 5 for all vehicles having different mounting pitches, using the small case 5 for a relatively large vehicle reduces the light emitting area of the lighting device relative to the size of the vehicle. The function as a vehicle interior lighting device may be impaired.
An object of the present invention is to provide a mounting structure for a lighting device for a vehicle interior that enables the use of the same case to reduce the mounting man-hours and management man-hours of the lighting device and that can sufficiently perform the function as the lighting device. It is in.
[0005]
[Means for Solving the Problems]
As shown in FIGS. 1 and 3, the invention according to claim 1 includes a plurality of vertical bones 12 extending in the traveling direction of the vehicle 10 and a plurality of horizontal bones 13 extending in the vehicle width direction on the lower surface of the roof panel 11 of the vehicle 10. Are provided in a lattice shape, and a plate-like insulator 16 is inserted between the vertical bone 12 and the horizontal bone 13, and a case 18 for storing and holding a fluorescent lamp 17 is inserted into the vertical bone 12 and the horizontal bone. 13 is an improvement of the mounting structure of the lighting device for the vehicle interior that is mounted between 13 through the bracket 21.
Its characteristic configuration is horizontal piece 21a and the horizontal piece 21a of the end fixably constructed in the longitudinal bone 12 or transverse bone 13 provided on a vertical piece 21b for supporting the lower surface of the bracket 21 insulator 16, and 21b And the case 18 is attached to the lower part of the horizontal piece 21a , and the insulator 16 covers the plate-like heat insulating material formed according to the size of the vertical bone 12 and the horizontal bone 13 and the heat insulating material, and It is in the place comprised with the film which can reflect the light of the fluorescent lamp 17. FIG.
[0006]
By attaching the case 18 to the lower part of the horizontal piece 21a, the case 18 is fixed at a predetermined position regardless of the mounting pitch of the longitudinal bones 12 and 12 or the mounting pitch of the horizontal bone 13, and a relatively small case. By using 18, the same case 18 can be used even when the mounting pitch of the longitudinal bones 12, 12 and the horizontal bone 13 is changed.
When the insulator 16 includes a film capable of reflecting the light of the fluorescent lamp 17, the relatively small case 18 is used in a large vehicle having a relatively large dimension between the longitudinal bones 12 and 12 or the lateral bone 13. Even so, the light emitted from the fluorescent lamp 17 is reflected by the insulator 16 to effectively illuminate the vehicle interior.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described in detail with reference to the drawings.
As shown in FIGS. 1 to 3, two vertical bones 12, 12 extending in the traveling direction of the bus 10 and a plurality of horizontal bones 13 extending in the vehicle width direction are latticed on the lower surface of the roof panel 11 of the bus 10. It is provided in the shape. The cross-sectional shape of the vertical bone 12 is formed in a substantially Z shape, and the cross-sectional shape of the horizontal bone 13 is formed in a rectangular tube shape (FIGS. 1 and 2). A lighting device 14 is inserted and fixed between the longitudinal bone 12 and the lateral bone 13.
[0008]
As shown in FIG.1 and FIG.2, the illuminating device 14 is the case 18 which accommodates and hold | maintains the plate-shaped insulator 16 inserted between the vertical bone 12 and the horizontal bone 13, and the fluorescent lamp 17 (FIG. 1). With. The insulator 16 of the present invention is inserted for the purpose of inherent heat insulation that blocks the heat from the roof panel 11 and for reflecting the light from the fluorescent lamp 17. Therefore, the insulator 16 is configured to be able to reflect the light from the fluorescent lamp 17. The insulator 16 in the present embodiment is made of polyester felt, and the lower surface of the insulator 16 is covered with a highly flame retardant polyurethane film in order to reflect the light from the fluorescent lamp 17. The plate-like insulator 16 configured to reflect this light is formed according to the size of the longitudinal bone 12 and the transverse bone 13 and has a slight gap between the longitudinal bone 12 and the transverse bone 13. Configured to be insertable.
[0009]
The case 18 is made by bending a steel plate, and a rising portion 18a for reinforcement is formed around it. The case 18 is provided with a pair of supports 19 and 19 that support both ends of the fluorescent lamp 17 and a ballast (not shown) that restricts the current after the discharge of the fluorescent lamp 17 that is turned on by a power source to a constant level. The fluorescent lamp 17 is accommodated in the case 18 by being supported at both ends by a pair of support tools 19, 19. The case 18 is attached via a bracket 21 between the longitudinal bone 12 and the lateral bone 13 into which the insulator 16 is inserted.
[0010]
The bracket 21 has a horizontal piece 21a and a vertical piece 21b formed at the end of the horizontal piece 21a, and a pair of vertical pieces 21b in the present embodiment is provided at both ends of the horizontal piece 21a. A hole 22 for screwing the vertical bone 12 is formed in the vertical piece 21b of the bracket 21, and a first screw hole 23 is formed in the vertical bone 12 corresponding to the hole 22 (one of FIG. 1). (Shown in vertical strip). The horizontal piece 21a is formed horizontally so as to support the lower surface of the insulator 16 with the vertical piece 21b attached to the longitudinal bone 12, and a second screw hole 24 for attaching the case 18 to the lower part of the horizontal piece 21a is formed. Formed (FIG. 2).
[0011]
An attachment hole 13a (FIG. 1) is formed in the lower part of the horizontal bone 13 near the longitudinal bone 12, and a long hole 32a is formed in the rails 32, 32 facing the attachment hole 13a. A rivet 33 can be inserted into the mounting hole 13a and the long hole 32a. As shown in FIG. 1, four ribs 32 b to 32 e protrude below the lower surface of the rail 32, and two ribs 32 b and 32 c of these ribs 32 b to 32 e are provided on the lower surface of the rail 32. The molding 34 that covers is locked. Of the remaining two ribs 32d and 32e, the lower surface of one rib 32d is in contact with the upper surface of the side edge of the globe 37 covering the opening via the cushion 36, and the remaining one rib 32e is in contact with the globe 37. The stopper 38 for preventing the dropout is locked. Reference numeral 39 denotes a ceiling inner plate.
[0012]
A procedure for mounting the vehicle interior lighting device thus configured will be described.
As shown in FIGS. 1 and 2, when the lighting device 14 is attached to the ceiling of the bus 10, the insulator 16 is first inserted between the vertical bone 12 and the horizontal bone 13, and then the pair of brackets 21 and 21 are inserted. . When the brackets 21 and 21 are inserted, the horizontal piece 21a is inserted horizontally so as to support the lower surface of the insulator 16, and in this state, the holes 22 formed in the vertical pieces 21b and 21b are respectively formed in the longitudinal bone 12. The first set screw 27 is loosely inserted into the hole 22 and is screwed into the first screw hole 23 (FIG. 1).
[0013]
Next, the case 18 is attached to the brackets 21 and 21. The case 18 is attached by aligning the through hole 18b (FIG. 2) formed in the case 18 with the second screw hole 24 (FIG. 2) formed in the horizontal piece 21a of the bracket 21, and passing the second set screw 28 therethrough. This is performed by loosely inserting into the hole 18b and screwing into the second screw hole 24, whereby the case 18 is fixed at a predetermined position. In this state, electric wires and connectors (not shown) in the case 18 are electrically connected. Therefore, even if the mounting pitch between the longitudinal bones 12 and 12 and the horizontal bones 13 provided in a lattice shape is changed by using the relatively small case 18, the same case can be obtained by changing the brackets 21 and 21. 18 can be fixed in place.
[0014]
Next, the pair of rails 32, 32 are respectively applied to the lower surface of the horizontal bone 13 along the longitudinal bones 12, 12, and the long holes 32 a of the rails 32, 32 are made to coincide with the mounting holes 13 a formed in the horizontal bone 13. If the long hole 32a and the mounting hole 13a coincide with each other, the rivet 33 is inserted into the long hole 32a and the mounting hole 13a, and the tip portion of the rivet 33 protruding from the mounting hole 13a is pushed and widened to form the pair of rails 32, 32. It fixes to the horizontal bone 13 along the longitudinal bones 12 and 12, respectively. Further, both ends of the fluorescent lamp 17 are attached to a pair of supports 19, 19 provided on the case 18, and a globe 37 is attached so as to block between the rails 32, 32 at the bottom of the case 18. Thereafter, the globe 37 is fixed with a stopper 38 and the lower surface of the rail 32 is covered with the molding 34 and locked. This completes a series of operations.
[0015]
In the above-described embodiment, the polyester felt is used as the insulator 16. However, the insulator 16 is not limited to this and may be a heat insulating material such as urethane or glass wool as long as it has a heat insulating action.
Further, in the above-described embodiment, the lower surface of the insulator 16 is covered with a highly flame-retardant polyurethane film so as to reflect the light of the fluorescent lamp 17, but the covering film can reflect the light of the fluorescent lamp 17. However, an aluminum foil or the like may be used as long as it has high flame retardancy. As a method for mounting the film, the end portion may be fixed with an adhesive tape after being wound around the insulator 16, or the entire film may be bonded to the lower surface of the insulator 16 using an adhesive.
Further, in the above-described embodiment, the bracket is fixed to the vertical bone, but the bracket is not limited thereto, and the bracket may be fixed to the horizontal bone, and the vehicle may be a truck or other vehicle instead of the bus.
[0016]
【The invention's effect】
As described above, according to the present invention, the insulator is configured to be able to reflect the light of the fluorescent lamp, and the vertical piece is configured such that the bracket supports the lower surface of the insulator and the vertical or horizontal bone. Since the case is attached to the lower part of the horizontal piece, the same case can be determined by using a relatively small case regardless of the vertical bone mounting pitch or horizontal bone mounting pitch. It is possible to fix in the position. When a relatively small case is used in a large vehicle with a relatively large size between the vertical and horizontal bones, the light reflected from the fluorescent light leaking from the case is reflected by the insulator to make the interior of the vehicle effective. Illuminate. As a result, it is possible to use the same case and reduce the number of man-hours for attaching and managing the lighting device when the case is changed, and at the same time, fully function as a lighting device for the vehicle interior that illuminates the vehicle interior. Can be made.
