Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle high mount stop lamp for use in passenger cars and the like.

[0002]

2. Description of the Related Art In an automobile having a relatively low vehicle height such as a passenger car, a stop lamp has a low position from the ground. It may be difficult to see the stop lamp provided at the position. Therefore, an auxiliary stop lamp is provided at a high position of the vehicle body. This is a high mount stop lamp. In the case of passenger cars, this high mount stop lamp is placed on the flat surface of the rear portion of the rear seat backrest, and its light passes through the rear window glass and is visually recognized by the following vehicle.

By the way, since the rear window glass is inclined, it is necessary to adapt the rear shape of the housing placed on a flat surface to the inclined surface so that the light of the bulb does not leak in directions other than the rear direction. The structure will be described. In FIG. 4, 1 is an automobile, 2 is a rear window glass, 3
Is a stop lamp. Rear seat backrest 4
On the rear flat surface 5, a high mount stop lamp 6
Is placed.

FIG. 5 shows the structure of the high mount stop lamp 6. A housing 7 is placed on the flat surface 5 and is fixed thereto by an appropriate means.
A bulb 9 and a lens 10 are provided. Although illustration of the electric wire is omitted, it is connected in parallel with the bulb of the stop lamp 3 at the rear part of the vehicle body. The housing 7 has a rectangular or oval box-like shape when viewed from the rear window glass 2 side, and the shape when viewed from the side (shape shown in cross section in the figure) is such that the lower part is longer than the upper part. The entire circumference of the opening is kept equidistant from the rear window glass 2 so as to correspond to the slope of the rear window glass 2. The base of a rubber boot 11 called an end rubber is attached to the outer periphery of the opening by fitting, and the tip of the boot is pushed open and brought into pressure contact with the inner surface of the rear window glass 2.

In this structure, when the driver depresses the brake pedal to stop or decelerate the vehicle, a stop lamp switch (not shown) is turned on, and the high mount stop lamp 6 is turned on together with the stop lamp 3 at the rear of the vehicle body. These lights inform the driver of the following vehicle that the vehicle is stopped or slowed down. The rear window glass 2 is inclined, but the high mount stop lamp 6 is the boot 1
Since they are in contact with each other, the light from the bulb 9 does not leak in directions other than the rear direction.

FIG. 6 shows another conventional example. In this case, a cylindrical body is not provided, and a flange 7a that is widened outward is formed in the opening of the housing 7, and the flange 7a is brought into contact with the rear window glass 2.
The flange 7a can eliminate the need for a rubber cylinder, but it is difficult in terms of adhesion to the rear window glass 2. In addition, the function of the high mount stop lamp is the same as that shown in FIG.

[0007]

In both of the prior arts, in order to completely prevent light from leaking from the contact surface between the boot 11 or the flange 7a and the rear window glass 2, the mounting position of the housing 7 is accurately determined. There is a need. Of course, the same vehicle model is accurately mounted at a fixed position, but different vehicle models may not be mounted at the same position because the rear window glass 2 may have different rear conditions. As a solution to this, there is one in which a bellows is interposed between the opening of the housing 7 and the rear window glass 2 (Japanese Utility Model Laid-Open No. 63-22253).
See Japanese Utility Model Laid-Open No. 63-133435, etc.). By inserting the bellows, it is possible to absorb some dimensional difference. However, the bellows have a problem in appearance.

The present invention has been made in view of this point, and even if there is a dimensional difference in the mounting position of the housing 7 with respect to the rear window glass 2, the dimensional difference is absorbed by adjustment, and light leakage is reliably prevented. It is intended to provide a high mount stop lamp for a vehicle that is capable of providing excellent appearance.

[0009]

As a means for solving the above-mentioned problems, the present invention provides a housing, which accommodates a valve inside and is open at the rear, on the vehicle interior side of a rear window glass, and the housing has a tip end. Accommodates a tubular body having a length reaching the rear window glass, and a guide mechanism including a slide groove extending in the front-rear direction and a ridge is provided between the outer peripheral portion of the tubular body and the inner wall of the housing. It is characterized in that an adjusting screw for moving the tubular body is provided between the body and the housing.

[0010]

With this structure, by rotating the adjusting screw from the outside of the housing, the tubular body is advanced and retracted with respect to the housing, and the tip of the tubular body is brought into contact with the rear window glass. Light does not leak to the outside due to the front end of the cylinder contacting the rear window glass. Fine adjustment is possible because the adjustment screw is used to move the cylinder back and forth.
Since the movement is guided by the fitting of the slide groove and the protrusion, it is smoothly and linearly performed.
