LAMP FOR VEHICLES Filed larch 7, 1931 ii a 5: 2. 5
Patented May 16, 1933 UNITED STATES PATENT OFFICE KARL KLEINEBT, OI STUTTGART, GERMANY, ASSIGNOR TO ROBERT BOSCH AKTIENGEBELLBCHAFT, O1 STUTTGART, GERMANY LAMP FOR VEHICLES Application filed March 7, 1881, Serial No.
The present invention relates to lamps and more particularly to the mounting of lamps for use with automobile and other vehicles.
It is well known to mount vehicle lamps in holders or supports by means of clamps. Generally the clamp is made of two parts and enshrouds a connecting tube fixed to the lamp. This however makes the manu- 1 facture of clamps expensive.
For the purpose of obtaining a securing clamp which is made of two parts, but consists of as few as possible separate elements the present invention provides for a curvated portion on the lamp casing which functions as one part of the clamping yoke.
The present invention is more particularly described by way of example with reference to the accompanying drawing which illustrates one form of construction and in which?- Figure 1 is a partial side elevational view of a lamp casing and a partial section through the securing device.
Figure 2 is a sectional view on the line AB of Fi 'ure 1.
A base tlange 2 includes a portion somewhat convex in section as illustrated at 3, this portion havingan opening for a lamp support 4. The base 2 is welded or otherwise rigidly secured to a paraboloidal lamp casing 1. One end of an element 5 is riveted to the interior of the casing 1, whilst the other end is adjustably secured to the casing 1 by means of a screw bolt 6. The element 5 together with the convex portion 3 of the base flange 2 together form the oke in which are disposed two clamping c eeks 7.
These cheeks are kept out of engagement with each other by helical springs 8 in order to facilitate the insertion therebetween of the support 4 and together form a cylindrical element having a transverse bore for the support 4.
A hole is formed in the element 5 so that a cable for the lamp may be passed through the hollow lamp support 4 and thence through the element and into the lamp cas- When it is desired to adjust the position 520,921, and in Germany March 15, 1930.
of the lamp relative to its support the clamping screw 6 is loosened whereupon the lamp and the checks 7 are angularly displaced about the vertical axis of the support 4. Further the lamp itself may be swung about 55 the checks 7 and support 4 about a horizontal axis. As the lamp need. only be inclined upwards or downwards by a small angle when being adjusted, the inclination maybe. limited in a simple manner by the no amount of opening in the lower yoke 3. When the lamp is in the desired position, the yoke 5 is tightened by the clamping screw 6 and the lamp is clamped on the support 4 by the clamping checks 7.
Since the securing device is mounted in the interior of the lamp it lies near to the centre of gravity of the lamp which is a (lesirable featurein order to keep the device rigid.
If desired, however, the securing device. may be mounted on the outside of the casing as distinct from the form of construction described in the drawing by way of example.
I claim:
1. A support for a. lamp comprising a tubular member, a convex portion on the casing of the lamp and slotted to receive said tubular member, a clamping member 30 secured to said casing adjacent said convex portion and having a slot formed therein and clamping cheeks between said clamping member and said convex portion for rigidly gripping said tubular member after this has been passed through the slot in said convex portion.
2. A lamp comprising a support, a casing having a convex portion thereof and a slot formed therein a slotted clamping member rigidly secured to said casing at one end and adjustably secured to the casing at its other end, semi-cylindrical clamping cheeks disposed between said clamping member and said convex portion and having a slot formed therein for the reception of said support and means to rigidly engage said support by said clamping cheeks and said clamping cheeks by said clamping member and convex portion in any one of a number of positions about vertical and horizontal axes.
3. A lamp comprising a support, a casing having a convex portion thereof and a slot formed therein, a slotted clamping member' rigidly secured to said casing at one end and adjustably secured to the casing at its other end, seinicylindrical clamping cheeks disposed between said clamping member and said convex portion and having a slot formed therein for the reception of said support, springs normally. maintaining said clamping cheeks apart and means to rigidly engage said support by said clamping cheeks and said clamping checks by said clamping member and convex portion in any one of a number of positions about vertical and horizontal axes.
In testimony whereof I have hereunto afiixed my signature.
KARL KLEINERT.
