Abstract

PURPOSE:To make rearward sight securable yet wider, by attaching a lamp box to the inside of a car room so as to come into contact with rear window glass, while keeping a back plate, being projected to the inside the car room, in succession so as to be almost flush with a rear wall surface in the car room. CONSTITUTION:A rear wall surface inside a car room of a hatch back type car, namely, the vicinity of a lower end edge of rear window glass 12 is covered with a flat rear trim 16 whereby a lamp box 13 is not projected to the inside of the car room at all, therefore space inside the car room is well available so effectively as compared with the conventional lamp box 2 shown in dotted lines, while rearward sight becomes so well. In addition, a bulb 18 is built in a lower part inside the box 13, and since this bulb light is reflected by an upper reflector 19, throwing light to a rear part of the car, an area of the box 13 accounting for the rear window glass is reducible.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a vehicular lamp, and more particularly to a vehicular lamp suitable for a stop lamp disposed at a high position in the rear of a vehicle.

(Background of the Invention) In order to prevent a double collision of vehicles, it is necessary to quickly inform two or three vehicles behind about the brake operation of the own vehicle. For this reason, it has been proposed to provide a stop lamp at a higher elevation of the vehicle, separate from the normal stop lamps provided on both sides of the rear of the vehicle.

Conventionally, as a lamp of this kind arranged at a high position, for example, there is a lamp shown in Japanese Patent Application Laid-Open No. 57-74237.

FIG. 1 is a sectional view showing an example of the installation of the lamp in the publication, and does not show the case where it is applied to a Hudgeback type vehicle.

As shown in the figure, this lamp has a lamp box 2 which is open on the rear window glass 1 side and whose interior side projects horizontally and is attached to the lower end of the rear window glass 1 by adhesive. Also, the back plate 3 of the lamp box 2
A bulb 4 serving as a light source is mounted horizontally through a socket 5, and the light from the bulb 4 is reflected toward the rear of the vehicle by a reflector 6 made of a parabolic mirror.

Furthermore, a red lens (or a red transparent plate) 7 is attached to the inner surface of the rear window glass 1, and the light from the bulb 4 is irradiated as red light. In the figure, 8 indicates the inner panel of the back door, and 9 indicates the rear trim.

However, in such a conventional stop lamp, the vertical dimension of the lamp box 2 must be at least as large as the outer diameter of the flapper 6, which obstructs the rear view and also obstructs the rear view. , a large protrusion M is required in the horizontal direction inside the vehicle interior, which not only narrows the space inside the vehicle interior but also is unfavorable in terms of the appearance of the interior of the vehicle interior.

(Object of the Invention) An object of the present invention is to provide a vehicle lamp that can secure more rearward visibility for the driver, occupies less space in the vehicle interior, and has a good external appearance in the vehicle interior. be.

(Structure of the Invention) In order to achieve the above-mentioned object, the present invention has a light projecting window which is directed toward the rear of the vehicle on the inside of the vehicle at the lower end of the rear window glass, and the window surface is brought into contact with the rear window glass. The lamp box is mounted on the lamp box, and the back plate of the box that protrudes toward the inside of the vehicle is connected to the rear wall of the vehicle so that it is approximately flush with the rear wall surface of the vehicle interior, and a bulb that serves as a light source is built into the box. It is characterized by becoming.

(Explanation of the Embodiments) FIG. 2 is a diagram showing the mounting state of the vehicle lamp according to the present invention, and FIG. 3 is a sectional view taken along the line A-Δ in FIG. 2.

As shown in FIG. 3, the back door 10 of a hatchback type vehicle is made up of an outer panel 10a and an inner panel 10b paired with each other with an appropriate gap, and a sealing material is provided at the center opening of the door 10. A window glass 12 is fitted through 11.

A plastic lamp box 13 is provided on the inside of the vehicle interior corresponding to the lower edge of the rear window glass 12. The box 13 is positioned so that its light projection window 13a faces toward the rear of the vehicle and the window surface abuts the window glass 12. Furthermore, the box back plate 13b protruding toward the interior of the vehicle is at the same level as the inner panel 10b. It becomes.

Further, the box 13 is fixed to the inner panel 10b with bolts 15 via a bracket 14, and a rear trim 16 is fixed to the compartment side of the box 13 so as to cover the inner panel 10b and the lamp box 13. Here, since the back plate 13b and the inner panel 10b are at almost the same level and there is no difference in level, the inner panel 1
0b and the rear trim 16 that covers the lamp box 13 is flat. Therefore, when viewed from the passenger compartment side, the interior walls of the vehicle are flat despite the presence of the lamp box 13, and the exterior appearance is good.

Box back plate 1 located at the bottom of the lamp box 13
3b, a socket 17 is vertically mounted, and a bulb 18 is fixed to this socket 17. on the other hand,
On the inner surface 13c of the upper part of the bottom facing the valve 18,
A reflector 19 in the form of a plane mirror is attached, and the light from the bulb 18 is reflected toward the rear of the vehicle.

A red lens plate (or a red transparent plate) 20 is attached to the light projection window 13a of the lamp box that contacts the window glass 12, so that red light is emitted to the rear of the vehicle, as shown in FIG. is now irradiated. Moreover, since the lamp is arranged at a high position on the vehicle, the braking operation of the own vehicle can be reliably communicated to the vehicles two or three vehicles behind.

According to the above configuration, the rear wall surface of the vehicle interior, that is, the vicinity of the lower edge of the rear window glass 12 has a flat rear trim 1.
6, there is no special protrusion into the interior of the vehicle despite the presence of the lamp box 13, resulting in an extremely good appearance.

Further, compared to the conventional lamp box 2 shown by the broken line in FIG. 3, the amount of protrusion into the vehicle interior is smaller, so that the interior space of the vehicle can be used effectively.

Furthermore, a structure is adopted in which a bulb 18 is built into the lower part of the box 13 and the light emitted from the bulb is reflected by the upper reflector 19 in the box 13 and projected toward the rear of the vehicle. Depending on the inclination angle, the area occupied by the rear window glass 12 above the lamp box 13 can be reduced, and as a result, the vertical dimension can be made smaller compared to the conventional example of JP-A-57-74237. More rearward visibility can be secured.

In the above embodiment, the lamp box 13 is made of plastic or the like which is separate from the inner panel 10b or the outer panel 10a.
Of course, the lamp box 13 may be formed by bending the outer panel 0b or the outer panel 10a into a cross-sectional shape.

(Effects of the Invention) As described above in detail, the vehicle lamp according to the present invention secures visibility to the rear of the vehicle, reduces the space occupied in the vehicle interior, and has a good appearance. .
