Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a lamp frame that is attached to a photo lamp or the like embedded in the front part of a bumper of an automobile. Here, explanation will be given by taking a photo lamp as an example, but the design frame of the present invention is not particularly limited and can be applied to any type of lamp that is embedded in a bumper, such as a cross lamp or a direction indicator lamp.

<Prior Art> FIG. 4 is a partial perspective view of the front part of an automobile, which is the area to which the design frame is applied, and FIG. 5 is a sectional view of a conventional design frame in use.

A cylindrical design frame 11 made of soft synthetic resin is installed from the front between the outer periphery of a lamp 5 embedded in an opening 3 formed on the front surface of an automobile bumper 1 and the inner periphery 3a of the opening of the bumper 1. The frame body 11 is provided with an engagement groove 15 in front of the outer circumferential portion thereof, which fits into the inner circumferential edge 3a of the opening of the bumper 1, and the front end surface 12 and the front inner circumferential surface 13a are designed painted surfaces. This is a configuration where there is

In this configuration, if the clearance between the lamp outer periphery 5a and the design frame periphery is set to less than 1 mm, the design frame periphery 13 and the lamp outer periphery 5a will interfere with each other due to vibrations generated while the car is running. Abnormal noises may occur, or the surrounding surface of the frame 1
No. 3 (including the front inner circumferential surface 13a which is the designed painted surface) may peel off.

For this reason, conventionally the above clearance was set at 3 to 7 mm.
It was set to be large.

<Problems to be Solved by the Invention> However, as described above, if the clearance between the outer periphery of the lamp and the periphery of the design frame is large, the interior of the lamp can be seen through, which is undesirable from a design standpoint. For this reason, it is possible to fill the clearance with a sponge sealant, but this would result in a material with a different appearance being interposed between the lamp and the design frame, which is still undesirable from a design perspective. It is undesirable that extra material costs and labor are required to install the device.

<Means for Solving the Problems> In order to solve the above-mentioned problems, the present inventor made earnest efforts in development, and as a result, was able to come up with an automobile lamp frame having the following configuration.

A cylindrical frame made of soft synthetic resin that is installed from the front between the outer periphery of a lamp embedded in an opening formed in the front surface of an automobile bumper and the inner periphery of the opening of the bumper, the outer periphery of the frame being In a decorative lamp frame body that is provided with an engaging groove portion that fits into the inner circumferential edge of the opening of the bumper on the front side, and in which the front end surface and the front of the inner circumferential surface are designed painted surfaces, the design on the inner circumferential surface of the frame body is provided. A decorative frame for an automobile lamp, characterized in that a lamp abutting rib is formed on the circumferential surface of the frame at approximately the rear end position of the painted surface.

<Operations and Effects of the Invention> As described above, the decorative frame for automobile lamps of the present invention has lamp abutting ribs formed on the inner circumferential surface, so even if it receives vibrations while the car is running, the decorative frame remains intact. Since interference between the inner circumferential surface of the body and the outer circumferential surface of the lamp is prevented by the aforementioned lamp abutting ribs, overall interference does not occur as in the conventional case. Therefore, substantially no abnormal noise is generated, and the paint film peels off only at the tops of the ribs, so there is almost no risk of peeling of the paint film on the designed painted surface (inner peripheral surface front 13a).

The height of the lamp abutting ribs may be as small as 1 mm or less, and the clearance between the lamp outer periphery and the inner periphery of the design frame (excluding the ribs) is not so large that the interior can be seen.

Therefore, when the designed frame of the present invention is attached to a lamp, it is possible to impart an excellent design to the lamp.

<Examples> Hereinafter, the present invention will be described in detail based on examples. Note that parts that are the same as those in the conventional example are given the same reference numerals, and a part of their description may be omitted.

FIG. 1 is a perspective view of a decorative lamp frame showing an embodiment of the present invention, and FIG. 2 is a schematic cross-sectional view of the mounting state.

Opening 3 formed in the front of a bumper 1 of an automobile
A cylindrical frame 11A made of soft synthetic resin is installed from the front between the outer periphery 5a of the lamp 5 embedded in the bumper 1 and the inner periphery 3a of the opening of the bumper 1. Here, examples of the soft synthetic resin include polypropylene, polyvinyl chloride, etc., and this frame 1
1A is usually manufactured by injection molding or the like using these materials. An engaging groove portion 1 that fits into the inner peripheral edge of the opening of the bumper is provided at the front of the outer peripheral portion of the frame body 11A.
5, and the front end surface 12 and the inner peripheral surface front 13a are designed painted surfaces. At least the front end surface 12 and the front inner circumferential surface 13a, which are designed painted surfaces, are coated with a urethane coating or the like having excellent weather resistance and abrasion resistance.

In the illustrated example, the engagement groove 15 is formed by partially forming engagement strips 16 on the upper and lower outer circumferential surfaces of the frame, but it may of course be formed all around the outer circumferential surface of the frame. In the illustrated example, 7 is a lamp holding arm. Up to this point, the configuration is the same as the conventional example.

In this embodiment, a lamp abutting rib 21 having a front end at approximately the rear end position of the designed painted surface of the frame 11 is used.
A plurality of them are arranged extending in the axial direction at approximately equal intervals. The width and height of each lamp abutting rib 21 are usually 0.3 to 1 mm. Further, the cross-sectional shape of each rib 21 is not particularly limited, but it is desirable that the tip end be semicircular.

Next, the manner of use of the above embodiment will be explained.

As before, the outer periphery of the lamp 5 and the bumper 1
and the inner peripheral edge 3a of the opening from the front.
At this time, since the lamp abutting rib 21 is formed in the axial direction, even if the clearance with the lamp 5 is set to zero, the sliding resistance when assembling the design frame 11A is small, making the assembly work easier. The quality is also good. In addition, since the frame is made of soft synthetic resin,
By bending, the engagement groove 15 at the front of the outer circumferential portion and the inner circumferential edge 3a of the opening of the bumper 1 fit into each other.

After installation, in addition to the above-mentioned effects, a ventilation gap exists between the lamp outer periphery 5a and the design frame inner periphery 13 due to the presence of the plural lamp abutting ribs 21 in the axial direction. Heat dissipation is promoted and the possibility that the design frame 11A is heated and deformed due to lamp heat is reduced.

FIG. 3 shows a perspective view of a design frame 11B in another embodiment of the present invention.

In this embodiment, instead of the plurality of lamp abutting ribs in the axial direction in the above embodiment, an annular lamp abutting rib is provided at approximately the rear end position of the designed painted surface on the peripheral surface 13 of the frame body. 22 is formed.

The usage mode and effects of this example are the same as those of the above example, but the border of the design painted surface is between the ribs 2.
2 and the area behind the ribs 22 cannot be seen, so there is no need to paint the area behind the ribs 22, and only the design painted surface side needs to be painted, so the cost of painting can be reduced.

In addition, in the above description, the rib 2 in the axial direction
Although the embodiment has been described in which only one of the ribs 1 and 22 in the circumferential direction is formed, it is of course possible to use both types of ribs in combination.
