2. Description of the Related Art FIG. 5 shows an example of the structure of a conventional high mount stop lamp 90 of this type, which is mounted on a housing 91 of the high mount stop lamp 90 in close contact with a rear window 20 of an automobile. Is formed in a substantially cylindrical shape with a flat portion 91a provided on the irradiation direction side,
A light source substrate 92 and a light distribution lens 9 are provided in the housing 91.
After assembling the lamp components such as 3 from the side, the whole or a part of the flat portion 91a is adhered to the rear window 20 with the adhesive 94 for attachment. .

[0003]

However, in the above-mentioned conventional high mount stop lamp 90,
First of all, the mounting is performed by directly adhering the housing 91 to the rear window 20 with the adhesive 94, and the shape of the high mount stop lamp 90 is long in the horizontal direction. Stress due to the difference between the coefficient of thermal expansion of the formed resin and the coefficient of thermal expansion of the rear window 20 is applied to the adhesive 94, which causes a problem that reliability deteriorates such as peeling with the lapse of use time. First, when the high mount stop lamp 90 has a problem, the rear window 20 has to be replaced, which causes a problem in terms of repair.

Secondly, since it is attached to the rear window 20 by adhesion, the flat portion 9 for adhesion is provided on the surface of the housing 91 facing the rear window 20.
Since it is necessary to provide 1a, the housing 91 has a substantially cylindrical shape, and thus the light source substrate 92 and the light distribution lens 93 have to be inserted from the side, and the high mount stop lamp 90 is configured. However, there is a problem that the work becomes complicated and the assembling work also becomes complicated, and it has been a problem to solve these problems.

[0005]

As a concrete means for solving the above-mentioned conventional problems, the present invention is a high mount stop lamp which is long in the horizontal direction and which is closely attached to the rear window from the indoor side. In the above, the indoor side surface of the rear window is attached with at least two mounting retainers along the horizontal direction, and the housing of the high mount stop lamp is fixed to one of the mounting retainers, and at the same time, the other mounting retainers are attached. On the other hand, the problem is solved by providing a high mount stop lamp in which the housing is slidably mounted in a horizontal direction.

[0006]

EXAMPLES The present invention will now be described in detail based on the examples shown in the drawings. Reference numeral 1 in FIGS. 1 and 2 denotes a high mount stop lamp (hereinafter abbreviated as a lamp 1) according to the present invention, and the lamp 1 is mounted in close contact with a rear window 20 of an automobile. The points are similar to those of the conventional example, but according to the present invention, the housing 2
Is not directly adhered to the rear window 20, but is attached via the attachment retainer 10.

The structure of the present invention will be described in more detail below. The mounting retainer 10 is formed of a metal member in a shape suitable for mounting the housing 2 such as an L shape, and the chamber of the rear window 20. It is supposed to be adhered to the inner surface by an adhesive 11.

At this time, the mounting retainer 10 is adhered to at least two horizontal positions on the inner surface of the rear window 20 in the horizontal direction, so that the housing 2, that is, the lamp 1 can be mounted at a correct position without tilting. Is being done. Here, the number of the attachment retainers 10 to be adhered is determined by the degree of horizontal bending of the rear window 20, and if the rear window 20 is, for example, a flat surface, the attachment retainers 10 are provided at both ends of the housing 2. Two locations substantially corresponding to the portion are provided, and when the curvature is strong, three locations are provided at both ends of the housing 2 and a portion substantially corresponding to the center, and the housing 2 is arranged along the curvature of the rear window 20. I will let you.

The housing 2 is screwed by the mounting screw 12 to the mounting retainer 10 mounted on the rear window 20 as described above, whereby the lamp 1 is mounted on the rear window 20. In the present invention, the fixing of the housing 2 and the mounting retainer 10 by screwing is performed at only one place, and the other mounting retainer 10 is fixed.
In the above, the housing 2 is mounted as being slidable in the horizontal direction with respect to the mounting retainer 10.

FIG. 3 shows the above-mentioned structure, and the housing 2 is provided with an elongated hole 2a having a major axis along the longitudinal direction thereof, that is, the horizontal direction in the example of FIG. As described above, the attachment is performed by the attachment screw 12 via the washer 3 having the spacer portion 3a formed to be slightly thicker than the wall thickness of the housing 2 and fitted in the short diameter of the long hole 2a. The direction, that is, the horizontal direction in the example of FIG. 3, can be freely slid. Although not shown, it goes without saying that lamp components such as a light source substrate and a light distribution lens are mounted inside the housing 2 as in the conventional example.

Next, the operation and effect of the lamp 1 of the present invention having the above structure will be described. The housing 2
Is fixed to one position of the mounting retainer 10 adhered to the rear window 20, and the other mounting retainer 10 has a longitudinal direction,
That is, since it is slidably mounted in the horizontal direction, a large temperature change occurs in the environment such as summer and winter, and a difference in length occurs between the housing 2 and the rear window 20 due to a difference in coefficient of thermal expansion. Sometimes, the difference in length is absorbed by the sliding of the other mounting retainer 10 described above.

Therefore, the stress generated by the difference in length between the housing 2 and the rear window 20 is not applied to the mounting retainer 10 at any position, and therefore, the mounting retainer 10 is subject to the environmental conditions that are conventionally generated. Peeling does not occur and long-term reliability can be provided. As is apparent from the above description, the long diameter of the elongated hole 2a is the housing 2, the rear window 2
It may be determined in consideration of the coefficient of thermal expansion of 0 and the environmental conditions in which the lamp 1 is used.

Further, by virtue of the above-mentioned structure, unlike the case where the housing 2 and the rear window 20 are adhered by a conventional adhesive, the housing 2, that is, the lamp 1 can also be detached by attaching and detaching the mounting screw 12. It can be freely attached and detached, and even if a problem occurs in the lamp 1, it is not necessary to replace the rear window 20 as in the conventional example, and the repair work is simplified.

FIG. 4 shows another embodiment of the lamp 1 according to the present invention. As described above, the lamp 1 is mounted on the rear window 20 via the mounting retainer 10, so that the housing 4 is The surface facing the rear window 20 does not require a flat portion for adhesion which was conventionally required.

Therefore, in this embodiment, the surface of the housing 4 facing the rear window 20 is formed as the opening 4a, whereby, for example, the LED 5a is formed.
Even when a lamp component such as a light source board 5 on which the LED is mounted and a light distribution lens 6 for giving an appropriate light emission characteristic to the light emitted from the LED 5a is assembled in the housing 4, the lamp 4 is provided through the opening 4a. This can be done by screwing directly to a predetermined position, which simplifies the configuration and simplifies the assembling work as compared with the conventional method of inserting from the side. The operations and effects other than those described above are exactly the same as those of the previous embodiment, and detailed description thereof will be omitted here.

[0016]

As described above, according to the present invention, a mounting retainer is adhered to the inner surface of the rear window along the horizontal direction, and the housing is fixed to one of the mounting retainers and the other mounting is performed. The retainer is a high mount stop lamp in which the housing is slidably mounted in the longitudinal direction, for example, in the horizontal direction, so that the difference in length between the rear window and the housing caused by environmental temperature can be absorbed. It is assumed that no stress is applied to the bonded part of the product, preventing the installation from peeling off due to changes in environmental conditions in winter and summer, for example, and it has an excellent effect in improving the reliability of this type of high-mount stop lamp. Is played.

Further, with the above structure, the high mount stop lamp and the rear window can be freely attached and detached. For example, even if the high mount stop lamp has a problem, the high mount stop lamp and the rear window can be replaced together. It also has the effect of simplifying repair work by saving time and effort.

Further, by forming the surface of the housing having the above-mentioned structure in contact with the rear window as an opening, a lamp component such as a light source board and a light distribution lens can be attached from this opening, and the structure is simple. It is also possible to simplify and simplify the assembling work, and it also has an excellent effect in improving productivity.
