Description

25th

The invention relates to a focal point for Christmas tree lighting with an incandescent lamp socket that has an insulating jacket made of plastic and a spring pin arranged laterally on the insulating jacket with a leg associated with the insulating jacket and has a movable leg

In a known focal point of this type (US-PS 25 99 303) the spring clip is a stamped part Sheet metal with a self-contained, essentially rectangular frame, the upper half of which corresponds accordingly the rounding of the substantially cylindrical insulating jacket is curved and a pair of arcuate Has arms that embrace the insulating jacket and thereby the upper half of the frame, one leg of the Spring clip forms, hold it against the insulating jacket. The lower half of the frame is level with the lower half The end of the bulb holder is angled downwards and outwards and in one piece at its outer end formed with the second leg of the spring clip, which is otherwise separated from the frame and is folded in such a way that its upper half tends to fit within the upper frame half to put on the insulating jacket. The legs of the spring clip formed in this way each point at their upper one Half rows of teeth for clamping to a branch of a Christmas tree and form each with theirs lower half handle parts that are bent in such a way that the upper halves move apart when you presses the handle parts together

In the case of this known burner, it cannot be ruled out that the incandescent lamp holder may accidentally become unintentional loosens from the two arcuate arms of the spring clip encompassing the insulating jacket. The after Below and outside bevelled parts of the spring clip protruding to a considerable extent from the lamp socket are also unpleasant.

The invention is therefore based on the object of providing a Brennstellc of the type described above to be trained in such a way that it is more inconspicuous and yet more secure on a Christmas tree or the like can be.

The object is achieved according to the invention in that the leg of the spring clip assigned to the insulating jacket is formed by the insulating jacket itself and that the insulating jacket is at least one in the amount of Has metal parts of the bulb holder protruding bearing block on which the movable leg of the Spring clip is stored

In a preferred embodiment of the invention, the insulating jacket has on its outside in Clamping area of the spring clip one or more rows of teeth to reinforce the holding effect of the Spring clip on.

The invention is illustrated below with reference to schematic drawings of two exemplary embodiments individual explained it shows

F i g. 1 is a side view of a first embodiment a focal point;

F i g. 2 the to F i g. 1 associated front view;

F i g. 3 is a side view of a second embodiment a focal point; and

F i g. 4 the to F i g. 3 corresponding front view

The in F i g. 1 and 2 has an incandescent lamp socket partially cut open in FIG. 1 10, into which a candle-shaped incandescent lamp 12 is screwed and to which a spring clip 41 is connected is

The incandescent lamp socket 10 has an insulating jacket 16 into which the comparable incandescent lamp sockets customary metal parts 18 and pigtails 20 are embedded. From the outside of the insulating jacket 16 Two parallel bearing blocks 22 protrude, below which a row of teeth 24 is provided on the insulating jacket 16 The insulating jacket 16 thus forms one leg of the spring clip 14.

A second leg 28 of the spring clip 14 is mounted on the bearing blocks 22 by means of a hollow rivet 26. The second leg 28 also has a row of teeth 30 which is opposite the row of teeth 24

Above the hollow rivet 26 is a spring 32 partially received between the bearing blocks 22, shown in FIG Example of a simple compression spring, clamped between the insulating jacket 16 and the second leg 28, so that it strives to the rows of teeth 24 and 30 to press against each other.

The in F i g. The embodiment shown in FIGS. 3 and 4 differs from that according to FIG. 1 and 2 only in that a bearing block 22 - or a pair of such bearing blocks - arranged somewhat lower on the insulating jacket 16 is, however, in accordance with FIGS. 1 and 2 such that it is in the area of the metal parts 18 of the bulb socket 10 protrudes approximately radially from the insulating jacket 16. The rows of teeth 24 and 30 are shown in FIG. 3 and 4 arranged above the bearing block 22; accordingly, the spring 32 is below the tubular rivet 26 arranged.

In both illustrated embodiments, the articulated connection between the insulating jacket 16 and the second leg 28 can be produced in a different manner than with the hollow rivet 26.
