Description

[Detailed Description of the Invention] (Purpose of the Invention) This invention relates to the structure of an interior lighting lamp for a vehicle such as a bus.

The structure of a conventional vehicle interior lighting lamp is as follows. That is, as shown in FIG.
A chassis 12 is attached to the chassis with screws 13, a glove 14 is attached to the chassis with screws 15, and a decorative frame 16 is glued to the periphery of the glove to close the gap with the ceiling and hide the edge of the periphery of the glove. ing.

However, in response to the recent improvement in the interior design of vehicles such as buses, the following problems have been pointed out with respect to conventional interior lighting for vehicles, and solutions to these problems have been demanded.

(1) The glove mounting screws are visible from the outside and look bad, and do not blend in with the interior.

(2) Since a mounting screw part must be provided, the degree of freedom in the design of the globe, which determines most of the design of the lamp, is limited.

(3) When performing maintenance such as replacing the lamp, it is necessary to remove the screws each time to remove the globe.
Maintenance is troublesome.

(4) Since the decorative frame is glued to the glove, the decorative frame is wasted each time the glove is replaced.

(5) Due to deformation of the decorative frame, a gap is created between the ceiling and the decorative frame, causing light leakage.

(6) The glove is damaged due to the tightening stress of the mounting screw.

The purpose of this invention is to solve the above-mentioned structural defects of the conventional vehicle interior lighting.

(Structure of the invention) The structure of this invention will be explained below based on the embodiment shown in FIG.

The vehicle interior lighting lamp based on this invention is shown in Figure 2a.
As shown in the figure, a decorative frame 22 is attached to the end of the chassis 21 so as to cover the entire circumference, and the end of the glove 24 is inserted between the inner edge 23 of the decorative frame and the chassis. Gloves are attached to hold it in place. Attachment to the ceiling is performed by attaching the edge 20 of the chassis with screws 25 before attaching the glove. The decorative frame is made of a flexible material such as soft vinyl chloride resin, and is a long extruded item with a cross-sectional shape as shown in Figure 2b, and its bottom edge 26
The end portion 28 of the chassis is pushed outward and fitted into the groove 27 as shown in FIG. As shown in FIG. 2c, when the edge 20 of the chassis is attached to the ceiling 29 with screws 25, the bottom edge of the decorative frame is crimped, making the above-mentioned attached state even more solid. On the other hand, the glove is inserted between the chassis and the inner edge 23 of the decorative frame, so that it is held in place by the restoring force of the decorative frame. Also, by squeezing the glove and pushing it to one side, and pushing down on the other edge, it comes off from the inner edge of the decorative frame, making it easy to remove.

As for the decorative frame, an extrusion molded product made of soft vinyl chloride resin with the cross-sectional shape shown in Fig. 2b is exemplified, but it can be easily fitted into the edge of the chassis and the glove, and can be easily fitted into the end of the chassis and the glove can be fitted into the frame. The material is not limited to the embodiments, as long as it has sufficient elasticity to hold the material.

FIG. 3 shows the appearance of a vehicle interior lighting lamp with the above structure according to this invention.

(Effects of the invention) The following effects can be obtained with this invention.

(1) Glove installation screws are no longer required.

(2) The installed appearance becomes smarter and looks much better.

(3) The degree of freedom in glove design increases, making it easier to harmonize with the design of the vehicle interior.

(4) Attaching and detaching the glove becomes significantly easier. Therefore, maintenance becomes easier.

(5) When a conventional glove becomes defective and needs to be replaced,
It can be used over and over again without removing the decorative frame that had to be discarded along with the glove.

(6) The edges of the case and glove are wrapped around the entire circumference with a decorative frame, so there is no light leakage.

(7) Since the entire circumference of the glove is clamped to the chassis by the decorative frame, damage to the glove due to tightening stress that occurs when tightening screws is eliminated.

As described above, this invention has solved the problems that are currently required to be solved in the structure of interior lighting lights for vehicles such as buses, and has brought about many effects.
It will greatly contribute to the development of industry.
