Description

[Detailed description of the invention] This invention relates to a waterproof structure for lamps for automobiles, etc.

In general, lamps of automobiles and the like are designed to prevent rainwater from entering easily, but it is difficult to completely prevent the intrusion.

Therefore, a water draining device as shown in Japanese Utility Model Application Publication No. 55-174045 has been devised.

In contrast, the present invention has devised a waterproof structure for a lamp installed upwardly or almost upwardly in an automobile or the like.

The details of the present invention will be explained below with reference to embodiments shown in the drawings.

A lamp 2 is attached to a body panel 1 of an automobile or the like facing upward or diagonally upward.

That is, the flange portion 3a of the lamp body 3 which becomes the main body of the lamp 2
is covered with a packing 4, its lower surface is brought into contact with the body panel 1, and the lens 5 is brought into contact with its upper surface, and the mounting screws 6 are inserted into the through holes provided in these to assemble them all together. It looks like this.

Further, the lamp body 3 is provided with a bulb attachment part 3b, into which a bulb socket 7 is fitted and a bulb 8 is attached.

The gasket 4 is provided with an extension part 4b extending to the periphery of the bulb attachment part 3b of the lamp body 3 integrally with the part 4a that is inserted between the lamp body 3 and the lens 5.
A standing rib 4 is provided at the end of the valve mounting portion 3b so as to surround the valve mounting portion 3b.
C is a pretense.

Furthermore, in the extension part 4b of the packing 4, the standing rib 4C
A few drainage holes 4d are provided on the outside of the tank.

The drain hole 4d communicates with a drain hole 3C provided in the lamp body 3.

In addition, the drain hole 4d of the seal 4 and the drain hole 3C of the lamp body 3 are provided in an appropriate number at appropriate locations on the extension portion 4b in order to easily and completely drain rainwater etc. that have entered the lamp 2. It is something that can be done.

Now, when rainwater or the like enters the lamp 2, it enters the lamp 2 from the peripheral edge of the lens 5 despite the presence of the gasket 4 and flows along the upper surface of the gasket 4 to the extension portion 4b.

However, since the vertical rib 4C is formed, it will not flow beyond this into the bulb attachment part 3b of the lamp body 3.
The water is drained to the outside of the lamp body 3, that is, to the outside of the lamp 2, through the water drain hole 4d provided in the extension portion 4b and the water drain hole 3C of the lamp body 3.

Since the lamp of the present invention is installed facing upward or almost upward, and is constructed as described above, rainwater etc. that have entered the lamp 2 are blocked by the vertical ribs 4C and the drain holes 4 d, drained from 3C.

That is, since rainwater and the like do not enter the inside of the valve mounting part 3b and therefore the inside of the socket 7, there is an advantage that rust does not occur in this part and ignition failure does not occur.
