Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is intended to provide a new vehicular marker lamp for the purpose of reducing the number of parts and the number of assembling steps.

[0002]

2. Description of the Related Art A vehicular marker lamp is known which is arranged inside a rear window of an automobile for the purpose of improving the visibility of an intention to stop a succeeding vehicle.

For example, in Japanese Patent Laid-Open No. 64-109142, the upper and lower and rear parts of a light bulb arranged in a synthetic resin lamp body having an open front surface are covered with reflecting mirrors. Disclosed is a lamp having a configuration in which it is supported by a protrusion protruding from a rear wall and is spaced apart from the inner surface of the lamp body except for the support.

In the vehicular marker light a shown in FIG. 21, a synthetic resin lamp body b is composed of a main part b1 and a hood part b2 detachably attached to the front part of the main part b1. , Both are connected by screws c, c.

Then, the lens d formed of a transparent synthetic resin is adhered or welded to the hood portion b2 of the lamp body b in a state of being fitted inside the hood portion b2 near the front end.
It is fixed to.

In the lamp chamber e defined by the lamp body b and the lens d, a metallic reflecting mirror f is arranged, and the reflecting mirror f has a mounting screw g inserted through a part thereof. The lamp body b is supported by the main portion b1 by being screwed onto a protrusion h formed on the main portion b1.

I is a cylindrical lamp socket,
In the lamp socket i, a metal band j is wound around the lamp socket i, and the mounting screws k and k are respectively inserted into the insertion holes of the end portions of the metal band j and the corresponding insertion holes of the reflecting mirror f, and then the lamp body. By being screwed into the prepared holes m, m of the bosses 1, 1 formed in b, the bosses 1, 1 are held by the bosses 1, 1.

Reference numeral n denotes a light bulb, the base portion o of which is detachably attached to the lamp socket i.

P is rear window glass.

[0010]

By the way, in the above-mentioned vehicular marker lamp a, the main portion b1 and the hood portion b2 constituting the lamp body b are connected by the screws c and c, and Since the reflecting mirror f is a separate member from the lamp body b and is attached to the main portion b1 using the metal band j and the attaching screws k, k, the number of parts is large and the assembly is troublesome. There's a problem.

[0011]

The vehicle marker light of the present invention comprises:
In order to solve the above-mentioned problems, a lamp body is formed by an upper body and a lower body that are vertically divided, and a hood portion that surrounds the lens is integrally formed on the upper body or the lower body, and the reflection is performed. The mirror is formed integrally with the upper body or the upper and lower bodies, and the light source bulb is mounted in the mounting hole of the reflecting mirror.

[0012]

Therefore, according to the present invention, since the hood portion is formed integrally with the upper body or the lower body and the reflecting mirror is formed integrally with the upper body or the lower body, the number of parts is reduced. It is possible to reduce the steps of attaching the hood to the main part of the lamp body and attaching the reflecting mirror to the lamp body.

In the high mount stop lamp 1, however, the hood portion 3 is formed integrally with the lower body 2a of the lamp body 2, and the reflector portion 13 is formed integrally with the upper body 2b. Therefore, the number of components is small and the assembly is easy.

That is, when assembling the high mount stop lamp 1 and mounting it on the vehicle body, first, the lens 20 is temporarily fixed to the hood portion 3 of the lamp body 2, and
After attaching the light bulb 18 to the reflector portion 13, the upper body 2b is attached to the lower body 2a so as to cover the opening 5 of the lower body 2a.
The upper body 2b and the boss portion 6 are aligned with respect to each other by using the screws 35, 35, and the body attachment portion 26 of the bracket 25 is attached.
Tighten together. Then, the vehicle body mounting portion 2 of the bracket 25
If you attach 7 to the predetermined position of the car body with screws,
The work of mounting the high mount stop lamp 1 on the vehicle body is completed. When replacing the light bulb 18, after removing the light bulb 18 through the light bulb insertion hole 16 formed in the upper body 2b, a new light bulb 18 is inserted through the light bulb insertion hole 16.
Is located in the lamp body 2, and the glass bulb 18a can be inserted into the bulb mounting hole 14 from the back side of the reflector portion 13 and attached to the reflector portion 13, so that the work is easy.

In the above-mentioned embodiment, the reflector portion 13 is formed integrally with the upper body 2b, but as shown in FIG. 20, the reflector portion 13A is formed in the lower body 2 of the lamp body 2.
Of course, it may be formed integrally with a. It is also possible to integrally form the hood portion 3 on the upper body 2b.

[0047]

As is apparent from the above description, according to the invention of claim 1, the hood portion is integrally formed with the upper body or the lower body, and the reflecting mirror is provided with the upper body or the lower body. Since it is formed integrally with the, it is possible to reduce the number of parts and the number of assembling steps.

According to the second aspect of the invention, the heat radiation hole is formed in the upper body at a position located above the light emitting portion of the light source bulb, and the heat radiation hole is made of metal so as to cover the heat radiation hole from above. Since the bracket can be attached to the upper body and the lamp can be attached to the vehicle by this bracket, by using the bracket as a radiator plate and a mounting member, a dedicated member for heat dissipation is not required and the number of parts can be reduced. it can.

According to the invention of claim 3, an insertion hole for locating the light source in the lamp body is formed in the upper body, and the light emitting portion of the light source is inserted into the mounting hole of the reflecting mirror through the insertion hole. By doing so, the replacement work of the light source can be easily performed.
