DE395353C - Headlights with electric light bulb - Google Patents

Description

In electric headlights such as those used for automobiles and motor vehicles more recently, the incandescent lamp inside the reflector is in a cutout the same axially and removable from. arranged the rear lamp part.

This design now enables the light bulb to be removed easily without the lead wires to hurt.

ίο The essence of the present invention be ^ stands in a facility by means of which this handling even by less experienced people People can be carried out easily, and differs from the known arrangements of this type in that the contact lever establishing the connection to the incandescent lamp Is arranged resiliently pivotable, so that on the one hand the contact after spring pressure is produced and on the other hand after

ao swiveling out the contact lever to the opposite side, the removal of the Incandescent lamp can be done, thus changing the incandescent lamp without loosening screws happens.

With such an arrangement, the as remains Lead wire unaffected when removing the bulb, so that kinks and breaks, which can easily lead to significant disruptions, can be avoided.

The adjustment of the light bulb in relation to the focal point of the headlight is done in a known way independently of the power supply by moving forward or backward the lamp socket or the incandescent lamp with the help of an external thread that is cut onto the lamp socket and into the Fits internal thread of a ring, which is pressed onto the tubular extension of an insert is.

An example of this facility

for changing and adjusting the light bulb through the rear part of the lamp is in reproduced in the drawing.

It shows:

Fig. Ι the lamp housing in longitudinal section with the new bulb arrangement in view,

Fig. 2 shows the shape of the light bulb in section and Figs. 3 and 4 show the pivoting contact lever.

The facility is as follows:

In the lamp housing 1, the reflector 2 is attached, the center of which has a cutout, which is closed by an insert 3 with a tubular continuation. On the Continuation of the insert 3, a ring 4 with an internal thread is pressed into which the lamp socket 5 is screwed in. The lamp socket 5 is after the convex ao side of the reflector closed by an insulated base 6 with a corded flange 7. In the middle of this bottom is a sliding metal pin 15, which the Contact between the lever 9 and the bulb 14 establishes.

The light bulb contact consists of the resilient lever 9, which can be pivoted in the bracket 10 is mounted and by coil spring pressure 11 according to the arrow in Fig. r marked direction on the pin 15 hangs.

The cable 13 is at one end 16 mounted on the pivotable lever 9 isolated on a special plate, with the other end in switch 12, from where the line cable leads to the power source.

The handling is as follows:

If a new incandescent lamp is to be used, the sealing cap 17 is removed from the lamp housing ι unscrewed, the lever 9 in the opposite direction of the arrow outside, pivoted, the lamp holder on the corded flange 7 detected and with the approach 3 taken out of the rear part of the lamp housing, a new lamp inserted, the insert is pushed back into the cutout of the reflector 2, the lever 9 released and rotated on the corded flange 7 until the focus has taken place, whereupon the headlight with the cap 17 is closed again will.

Patent Claims: Fig. Fig. 3. Fig. 4. Headlight with electric light bulb, which in the apex of this "reflector in one" Cutout is arranged axially and can be removed to the rear, marked by a spring-mounted pivotable contact lever (9), the lies against the contact pin of the lamp socket, so that after pivoting the contact lever the way to take it out the light bulb is released from the reflector and the lamp housing without loosening screws.
