Description
本発明は、例えば鉄道車両や観光バス等の室内に設置される荷棚に関する。 The present invention relates to a cargo rack installed in a room such as a railway vehicle or a sightseeing bus.
例えば鉄道車両や観光バス等の荷棚は、一般的に、アルミニウム合金やステンレス鋼等の金属材料で構成され、車両構体の前後方向に沿って室内の両窓側の座席の上部に設置されている。通常、車内の照明灯は天井の中央付近に設けられているため、照明灯の光が荷棚に遮られてしまい、これにより窓側の座席には、中央側（通路側）の座席と比較して、十分な明るさを確保することが困難であった。 For example, cargo racks such as railway vehicles and sightseeing buses are generally made of a metal material such as aluminum alloy or stainless steel, and are installed on the upper part of the seats on both windows in the longitudinal direction of the vehicle structure. . Usually, the lighting in the car is installed near the center of the ceiling, so the light from the lighting is blocked by the cargo rack, which causes the window side seat to be compared to the center side (passage side) seat. It was difficult to ensure sufficient brightness.
一方、下記特許文献１には、金属製の荷棚本体と、荷棚本体の上面に配置された棚板と、荷棚本体の下面に配置された面状照明部とを備えた車両用荷棚が記載されている。上記面状照明部は、複数の照明用ＬＥＤが配列されたＬＥＤアレイと、所定の上下幅の隙間を挟んで上下にそれぞれ配置された反射拡散板および拡散照射板とを含む。複数の照明用ＬＥＤは、上記隙間に沿って車両の前後方向に並べられ、反射拡散板は白色のプラスチック板で構成され、拡散照射板は透明なプラスチック板で構成される。このような構成により、上記隙間内に照射された白色光は、反射拡散板によって拡散照射板に向けて反射拡散し、拡散照射板から拡散状態で下方へ出射することで、窓側の座席にも十分な照明光が照射されるとしている。 On the other hand, the following Patent Document 1 discloses a vehicle load provided with a metal load shelf body, a shelf plate disposed on the upper surface of the load shelf body, and a planar illumination unit disposed on the lower surface of the load shelf body. The shelves are listed. The planar illumination unit includes an LED array in which a plurality of illumination LEDs are arrayed, and a reflection diffusion plate and a diffusion irradiation plate, which are respectively arranged above and below with a predetermined vertical gap therebetween. The plurality of illumination LEDs are arranged in the front-rear direction of the vehicle along the gap, the reflection diffusion plate is formed of a white plastic plate, and the diffusion irradiation plate is formed of a transparent plastic plate. With such a configuration, the white light irradiated in the gap is reflected and diffused toward the diffusion irradiation plate by the reflection diffusion plate, and is emitted downward from the diffusion irradiation plate to the window side seat. It is assumed that sufficient illumination light is irradiated.
しかしながら、特許文献１に記載の荷棚においては、棚板と面状照明部とが上下に離間して配置されているため、荷棚の薄型化が図れないという問題がある。また、面状照明部の上面を形成する反射拡散板が白色のプラスチックで構成されているため、荷棚の下の座席から棚板上の荷物の有無を確認することができないという問題もある。 However, in the load shelf described in Patent Document 1, since the shelf board and the planar illumination unit are arranged apart from each other in the vertical direction, there is a problem that the load shelf cannot be thinned. In addition, since the reflection diffusion plate that forms the upper surface of the planar illumination unit is made of white plastic, there is also a problem that it is impossible to confirm the presence or absence of luggage on the shelf from the seat under the shelf.
以上のような事情に鑑み、本発明の目的は、薄型化を実現でき、座席から荷棚の上の荷物の有無を確認することができる荷棚を提供することにある。 In view of the circumstances as described above, an object of the present invention is to provide a cargo rack that can realize a reduction in thickness and can check the presence or absence of luggage on the cargo rack from a seat.

一方、第２の支持ユニット２２は、第１の支持ユニット２１と同様に、金属製のケーシング２２０（第２のケーシング）と、弾性部材２２３（第２の弾性部材）とを有する。ケーシング２２０は、灯体２２１と蓋体２２２とを有し、第１の支持ユニット２１におけるケーシング２１０と比較して同一の構成を有する点で共通するが、内部に光源を収容していない点で異なる。なお後述するように、ケーシング２２０の内部に光源（第２の光源）が配置されてもよい。 On the other hand, similarly to the first support unit 21, the second support unit 22 includes a metal casing 220 (second casing) and an elastic member 223 (second elastic member). The casing 220 has a lamp body 221 and a lid body 222 and is common in that it has the same configuration as the casing 210 in the first support unit 21, but does not contain a light source inside. Different. As will be described later, a light source (second light source) may be disposed inside the casing 220.
ケーシング２１０，２２０は、棚板１０に関して相互に対称的に構成される。弾性部材２２３も同様に、第１の支持ユニット２１における弾性部材２１３と同様に構成される。
第２の支持ユニット２２は、棚板１０の他端部１０Ｂを支持することが可能に構成される。ケーシング２２０は、棚板１０の他端部１０Ｂを挟持し、弾性部材２２３は、棚板１０の他端部１０Ｂとケーシング２２０との間に介装される。弾性部材２２３は、ケーシング２２０内への水分や塵埃の侵入を防止するための密封材として機能するとともに、棚板１０に作用する荷重をケーシング２２０において弾性的に吸収するための緩衝材として機能する。
The casings 210 and 220 are configured symmetrically with respect to the shelf board 10. Similarly, the elastic member 223 is configured similarly to the elastic member 213 in the first support unit 21.
The second support unit 22 is configured to be able to support the other end portion 10 </ b> B of the shelf board 10. The casing 220 sandwiches the other end portion 10 </ b> B of the shelf board 10, and the elastic member 223 is interposed between the other end portion 10 </ b> B of the shelf board 10 and the casing 220. The elastic member 223 functions as a sealing material for preventing moisture and dust from entering the casing 220 and also functions as a cushioning material for elastically absorbing the load acting on the shelf board 10 in the casing 220. .
第１及び第２の支持ユニット２１，２２のＹ軸方向の両端部は、一対のブラケット３０によって共通に支持されている。ブラケット３０は、典型的には金属材料で構成され、基部３１と、アーム部３２とを有する。基部３１は、略Ｚ軸方向に延び、その一端部３１０には、車両構体（車両の両窓側の側面）に複数のボルト等を介して固定される取付部３１０が設けられ、基部３１の他端部にはアーム部３２が連続的に形成される。基部３１及びアーム部３２は、中空の板材で構成され、これらの内部には、光源４１と接続される配線ケーブル等が収容される。 Both ends in the Y-axis direction of the first and second support units 21 and 22 are supported in common by a pair of brackets 30. The bracket 30 is typically made of a metal material and has a base portion 31 and an arm portion 32. The base portion 31 extends substantially in the Z-axis direction, and one end portion 310 thereof is provided with a mounting portion 310 that is fixed to the vehicle structure (side surfaces on the both windows side of the vehicle) via a plurality of bolts. An arm portion 32 is continuously formed at the end. The base part 31 and the arm part 32 are comprised with a hollow board | plate material, and the wiring cable etc. which are connected with the light source 41 are accommodated in these.
アーム部３２は、第１及び第２の支持ユニット２１，２２を支持し、基部３１の他端部から略Ｘ軸方向に突出するように形成される。本例では、アーム部３２の基部（車両の側面側）で第１の支持ユニット２１が支持され、アーム部３２の先端部３２０で第２の支持ユニット２２が支持される。アーム部３２の先端部３２０の突出方向は、Ｘ軸方向に平行な水平方向であってもよいし、Ｘ軸に対して所定角度上方に傾斜する方向であってもよい。基部３１とアーム部３２とのなす角度によって、棚板１０の設置角度が設定される。 The arm portion 32 supports the first and second support units 21 and 22 and is formed so as to protrude from the other end portion of the base portion 31 in a substantially X-axis direction. In this example, the first support unit 21 is supported by the base portion (side surface side of the vehicle) of the arm portion 32, and the second support unit 22 is supported by the distal end portion 320 of the arm portion 32. The protruding direction of the distal end portion 320 of the arm portion 32 may be a horizontal direction parallel to the X-axis direction, or may be a direction inclined upward by a predetermined angle with respect to the X-axis. The installation angle of the shelf board 10 is set by the angle formed by the base portion 31 and the arm portion 32.
以上のように構成される本実施形態の荷棚１において、棚板１０は、第１及び第２の透光板１１，１２の積層体で構成されるため、荷棚１全体の薄型化を実現することができる。また、棚板１０は、光源４１から一端部１０Ａへ入射した照明光Ｌを、上面１０２及び下面１０１で内部反射を繰り返しながら他端部１０Ｂへ向けて進行させつつ、光拡散層１３で照明光Ｌを棚板１０の両面に向けて拡散させる導光板として機能する。 In the cargo rack 1 of the present embodiment configured as described above, the shelf board 10 is configured by a laminated body of the first and second light-transmitting plates 11 and 12, so that the entire cargo rack 1 can be thinned. Can be realized. Further, the shelf plate 10 causes the illumination light L incident from the light source 41 to the one end portion 10A to travel toward the other end portion 10B while repeating internal reflection at the upper surface 102 and the lower surface 101, and is illuminated by the light diffusion layer 13. It functions as a light guide plate that diffuses L toward both sides of the shelf board 10.
例えば図５に示すように、棚板１０の内部へ入射した照明光Ｌは、第１及び第２の透光板１１，１２の界面に設けられた光拡散層１３によって拡散され、その拡散光Ｌ１，Ｌ２が第１及び第２の透光板１１，１２を透過する。拡散光Ｌ１は、第１の透光板１１を透過し、棚板１０の直下の座席を照明する照明光を形成する。一方、拡散光Ｌ２は、第２の透光板を透過し、棚板１０の直上を照明する照明光を形成する。 For example, as shown in FIG. 5, the illumination light L incident on the inside of the shelf board 10 is diffused by the light diffusion layer 13 provided at the interface between the first and second light-transmitting plates 11 and 12, and the diffused light. L1 and L2 pass through the first and second light transmitting plates 11 and 12. The diffused light L <b> 1 is transmitted through the first light transmissive plate 11 and forms illumination light that illuminates the seat directly below the shelf plate 10. On the other hand, the diffused light L <b> 2 is transmitted through the second light transmissive plate and forms illumination light that illuminates directly above the shelf plate 10.
このように荷棚１０は、その直下に設置された座席へ照明光を照射する面状発光体として構成されるため、当該座席に所望とする明るさを提供することが可能となる。また、第２の透光板１２が透光性を有するとともに、荷棚１０全体を薄型に構成することができるため、当該座席から棚板１０上に載置された荷物の存在を容易に視認することが可能となる。 Thus, since the load shelf 10 is comprised as a planar light-emitting body which irradiates illumination light to the seat installed just under it, it becomes possible to provide the brightness which desires the said seat. Moreover, since the 2nd translucent board 12 has translucency, and the whole cargo shelf 10 can be comprised thinly, presence of the load laid on the shelf board 10 from the said seat can be visually recognized easily. It becomes possible to do.
本実施形態においては、棚板１０の光拡散層１３が、第１及び第２の透光板１１，１２を相互に接合する透光性の接合層１３１と、接合層１３１の少なくとも一方の面に形成された光拡散性のドットパターン１３２とを有する。これにより、第１及び第２の透光板１１，１２を一体的に接合して棚板の必要な強度を確保することができるとともに、棚板１０の所望とする輝度分布を容易に得ることが可能となる。上記輝度分布としては、棚板１０の面内全域に均一な輝度が得られるように設定されてもよいし、任意の方向に輝度のピークが現れるように設定されてもよい。 In the present embodiment, the light diffusing layer 13 of the shelf board 10 has a light-transmitting bonding layer 131 that bonds the first and second light-transmitting plates 11 and 12 to each other, and at least one surface of the bonding layer 131. And a light diffusing dot pattern 132 formed on the substrate. Thereby, the first and second translucent plates 11 and 12 can be integrally joined to ensure the necessary strength of the shelf plate, and the desired luminance distribution of the shelf plate 10 can be easily obtained. Is possible. The luminance distribution may be set so that uniform luminance is obtained over the entire surface of the shelf board 10, or may be set so that a luminance peak appears in an arbitrary direction.
また、棚板１０の両端部１０Ａ，１０Ｂが第１及び第２の支持ユニット２１，２２を介してブラケット３０に支持されているため、荷棚１全体の剛性を高めることができる。さらに、第１及び第２の支持ユニット２１，２２が弾性部材２１３，２２３をそれぞれ有しているため、ケーシング２１０，２２０と棚板１０との間のシール性が確保されるとともに、ガラス製の棚板１０を金属製のケーシング２１０，２２０との接触による損傷から効果的に保護することが可能となる。 Moreover, since the both ends 10A and 10B of the shelf board 10 are supported by the bracket 30 via the 1st and 2nd support units 21 and 22, the rigidity of the cargo rack 1 whole can be improved. Further, since the first and second support units 21 and 22 have the elastic members 213 and 223, respectively, the sealing performance between the casings 210 and 220 and the shelf board 10 is ensured, and the glass The shelf board 10 can be effectively protected from damage due to contact with the metal casings 210 and 220.

For example, the lens portion 213d illustrated in FIG. 7 has a convex shape that protrudes toward the end surface of the one end portion 10A of the shelf board 10. In this case as well, since a certain condensing action is obtained for the illumination light incident on the lens portion 13c, the illumination light can be efficiently incident on the end surface of the one end portion 10A of the shelf board 10. A lens portion 213c shown in FIG. 6 may be further formed on the surface of the lens portion 213d on the light source 41 side.
