"VEHICLE LAMP"

The following statement is a full description of this invention, including the best method of performing it known to me/ us -1-

pPCpIFI1 1'77

1 he ;omisioriCr 01 rULCIAIb 2) CLEMENT HACK CO., Patent Attorneys, 140 William Street, Melbourne, Victoria, 3000, Australia 1 T

The invention relates to a vehicle

0@ lamp with a transparent light housing, which

is set on a base plate carrying the electrical 000

00 contact facilities and eventual reflectors and 0* 0O S

S 0 66S which is releasably connected with the said

base plate via self-locking elements formed by

00 elastic springy tongues arranged on the base

plate aud engaging with their free end the light *6 0 0O housing.

0.: In the known lamps of this kind the

S elastic tongue effecting the locking between the

light housing and the base plate lies outside on S

the light housing. This arrangement is not only 0S disadvantageous to the outside appearance of the 0@

lamp, but generally also requires a tool in order

to lift off the free end of the elastic tongue uUAMMUNWEALTH OF AUSTRALIA. I fssui fn nme seustralia nafmeIT L e.ii from the wall of the light housing so that the light housing can be released from the base plate. In order to simplify the release of the light pane, the change has been made already to let the outer end of the free tongue stand away from the housing wall like a handle,

C so that the elastic tongue can be lifted off

t- from the light housing without an additional

4 tool. This projecting end of the tongue results

in an increased danger of injury and also forms

recesses in which dirt can settle readily.

The object of the invention is to improve

this releasable locking connection for vehicle

lamps in such a way that the side wall of the

light housing is possibly free of noticeable

"i interruptions or projections respectively, and in

addition a release of the light housing, for instance

for the exchange of the incandescant bulb, can be

carried out simply and easily. This object is S 20 attained in accordance with the invention in that

the springy tongues are arranged inside of the light

housing and engage in a recess of the light housing

with an outward directed projection arranged at the

free end. In this way the light pane has only a

25 small interruption on its outer wall, through which

interruption the projection of the elastic tongue *0*0 protrudes and forms a press button for the release

of the light pane locking.

In an attractive embodiment of the

.nvention idea the projection at the end of the springy tongue is in the form of a button- shaped bulge, which projects into the opening in the light housing and fills this opening.

Here it is advantageous that the outer surface

of the button-shaped bulge forms a plane with

the outer surface of the light housing so that

the side wall of the light boumsing has basically

no projection or depression.

It is expedient to arrange and construct

4 the tongue in such a wa~y that it lies against the

wall of the housing. In this way the springy

tongue can receive a certain pretension so that

always a safe connection between the lig.8ht housing

and the base plate is achieved.

The drawing illustrates an attractive 060@ 0* embodiment of the invention wherein: C C 0*

*SOS Figure 1 shows a center section of the 00 6S 0*

@6 lamp, while em 0OS S Figure 2 a side view of the lamp. 6e S 6O 0S S 20 The shell-shaped light housing 1 made of C e.g. S 0Sg0 transparent synthetic material lies with its edge

2 on a shoulder 3 of the base plate 6 which carries

S0 the reflector 4 and the not illustrated contact SO 0 SO 66 arrangements of the incandescant lamp 5. Ths 6S *e.

6 25 fastening between light housing 1 and base plate 6 *0 @0 00 is attained by a releasable self-locking muap- 6 0O@00@ 6 connection, which is formed by the elastically 0

0 *OSSOO 6 pliable tongue 7 shaped to the base plate 6, which 0e 66 06 said tongue points to the light exit direction ad

protrudes into the light housing and by its button-

Ahaped bulgce 8 lfo rmed to the free endp which

said bulge engages in an opening 9 of the side

wall of the light housing 1. The bulge of the

free end of the elastic tongue 7 is made so

strong and so shaped that it fills the opening

S9 of' the light housing 1. In this way a smnooth

Sside wall of the light housing 1 is obtained

which is free from any sharp-edged projections

or depressions.

In order to release the light housing 1

from the base plate 6 pressu~re is exerted on the

button-shaped bulges 8 of the elastic tongues 7,

so that these are pushed out of the openings 9.

In this way the light housing 1 can be taken off

from the base plate 6.

:The elastic tongues 7 are so arranged

:and made that they lie againsrt the side wall of the iight housing I under pretension.
