Abstract

PURPOSE:To fit an illumination lamp to a car body without providing space for the bulb, changing and make an automobile, for example, compact and light. CONSTITUTION:In this illumination lamp 1 for vehicle, a slide rail part 5, on which a movable part 6 crossing an optical axis of a reflecting mirror 2 at a right angle can slide in the vertical direction and the movable part 6 can be disconnected at the upper end thereof, is provided in the back surface of the reflecting mirror 2. A socket 3 and a reflecting mirror cut-out part 2a cut out from a reflecting mirror 2 at a part, on which a bulb 4 abuts, and fitted to the socket 3 are fitted to this movable part 6. When a change of the bulb 4 is required, the movable part 6 is slid to the upper in the vertical direction to be disconnected from the slide rail 5, and the bulb 4 is changed outside of the illumination lamp 1 for a vehicle.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a headlamp, a fog lamp, and other lighting fixtures mounted on a vehicle, and more particularly to a structure for replacing the light bulb.

[0002]

2. Description of the Related Art FIG. 3 shows an example of the structure of a conventional vehicle illumination lamp 90 of this type, in which a socket 92 is fixed to the bottom surface of a reflecting mirror 91 and a light bulb 93 is replaced. This is performed by pulling out the light bulb 93 from the socket 92 rearward.

[0003]

However, in the above-described conventional vehicle illumination lamp 90, the bulb 93 is replaced by pulling it out backward as described above. When mounting the vehicle lighting 90, it is necessary to prepare a space for it in the rear of the vehicle lighting 90 in advance.

This causes an increase in the size of the entire vehicle, which is contrary to the design direction of recent automobiles in which size and weight reduction are required from the standpoint of energy saving. Therefore, the light bulb 93 is replaced. There is also a case where the mounting is performed without a space for this, but in this case, when replacing the light bulb 93, it is necessary to remove the vehicle lighting 90 itself from the vehicle body, and there is a problem that the replacement work becomes complicated. However, depending on the laws and regulations that differ from country to country, there is a problem that the entire vehicle having such a structure cannot obtain the type approval, and the solution to this point has been a problem.

[0005]

As a concrete means for solving the above-mentioned conventional problems, the present invention provides a vehicle illumination lamp in which a socket for replacing a light bulb is provided on the bottom surface of a reflecting mirror. On the back surface of the reflecting mirror, there is provided a slide rail part that allows a movable portion orthogonal to the optical axis of the reflecting mirror to be slidable in the vertical direction and is openable and detachable at the upper end, and the movable portion has the socket, A reflecting mirror cutout portion obtained by cutting out the reflecting mirror at a portion where the light bulb attached to the socket abuts by sliding of the movable portion is attached, and the slide rail portion and the movable portion are locked at a predetermined position. It is an object of the present invention to solve the problem by providing an illumination lamp for a vehicle, which is provided with a locking mechanism for

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described in detail based on an embodiment shown in the drawings. Reference numeral 1 in FIGS. 1 and 2 is a vehicle illumination lamp according to the present invention.
Like the conventional example, a socket 3 is provided on the bottom surface of the reflecting mirror 2 and the light bulb 4 can be replaced by the socket 3.

However, according to the present invention, the reflecting mirror 2
A substantially U-shaped slide rail portion 5 with the opening 5a facing upward is provided on the rear surface of the slide rail portion 5, and the slide rail portion 5 includes a movable portion 6 in a state substantially orthogonal to the optical axis Z of the reflecting mirror 2. For example, a fitting means such as a groove is provided, and the opening 5a is provided.
Both of them, that is, the slide rail portion 5 and the movable portion 6 can be freely attached and detached, and the movable portion 6 can be freely slid in the vertical direction after being fitted.

Here, in the present invention, the movable portion 6 is provided with the socket 3. Therefore, the socket 3 moves up and down as the movable portion 6 slides, and this movement reaches the opening 5a. In this case, the light bulb 4 is detached from the slide rail portion 5, so that the light bulb 4 can be replaced even in this detached state, that is, the light bulb 4 can be attached and detached without being affected by the surrounding conditions.

At this time, considering the state in which the movable part 6 is slid with the light bulb 4 attached to the socket 3, the light bulb protruding forward from the socket 3, that is, toward the inside of the reflecting mirror 2. Since 4 naturally comes into contact with and interferes with a part of the reflecting mirror 2, in the present invention, the portion of the reflecting mirror 2 that comes into contact with the light bulb 4 is cut out to form a reflecting mirror cutout portion 2a. The mirror cutout portion 2a is also the movable portion 6
It is supposed to be attached to.

Further, the slide rail portion 5 and the movable portion 6
Means that the movable portion 6 is the lower end portion 5b of the slide rail portion 5.
Is formed so as to provide a predetermined position with respect to the light bulb 4 and the reflecting mirror cutout portion 2a when it comes into contact with, and a locking mechanism such as a click structure by the spring 7 is provided at the predetermined position. Therefore, by bringing the slide rail portion 5 and the movable portion 6 into the locked state, the reflecting mirror 2 becomes a reflecting surface of, for example, one surface of the paraboloid of revolution with the reflecting mirror cutout portion 2a, and the light bulb 2 is It is arranged at a predetermined position such as the focal position of the reflecting surface.

Next, the operation and effect of the present invention having the above-mentioned structure will be described. When the movable part 6 is slid on the slide rail part 5, the light bulb 4 moves vertically, and the vehicle illumination lamp. The movable portion 6 can be detached from the reflecting mirror 2 without protruding beyond the state in which the movable portion 6 is attached to the rear of the mirror 1.

Therefore, the light bulb 4 can be replaced outside the vehicle illumination lamp 1 which is not affected by the surrounding conditions, and the movable portion 6 can be similarly attached after the replacement. Therefore, the vehicle illumination lamp 1 can be attached to the vehicle body without providing a space for inserting and removing the electric bulb 4 at the rear.

Further, the movable portion 6 has a structure in which the socket 3 for mounting the light bulb 4 and the reflecting mirror cutout portion 2a which interferes with the light bulb 4 are mounted.
When the movable portion 6 is at a predetermined position, the reflecting surface of the reflecting mirror 2 and the reflecting mirror cutout portion 2a is in a perfect state with no cuts and the like, and the reduction in illuminance caused by this configuration is prevented.

[0014]

As described above, according to the present invention, the movable portion, which is orthogonal to the optical axis of the reflecting mirror, is vertically slidable on the rear surface of the reflecting mirror and is openable at the upper end to be detachable. A rail portion is provided, the movable portion is provided with the socket, and a reflecting mirror cutout portion obtained by cutting out the reflecting mirror at a portion where a light bulb attached to the socket abuts by sliding of the movable portion, and Since the slide rail section and the movable section are provided with a locking mechanism for locking the movable section at a predetermined position, the movable section is slid upward in the vertical direction when it becomes necessary to replace the light bulb. By removing the light bulb outside the vehicle lighting lamp, the rearward movement of the light bulb does not occur during the replacement work, and the space for replacing the light bulb behind the vehicle lighting lamp is unnecessary. Is something Te, it possible to close the mounting of the vehicle body of the vehicle lighting, the overall size of automobiles, in which excellent effects in such weight.
