Patent-Treuhand-Gese1schaft for electric light bulbs mbH, Munich Lightning cube

The innovation relates to a flash cube for flat cameras with Piezo crystal or battery capacitor high voltage transformer circuit As an ignition voltage source and slot socket for accommodating flash lamps equipped with high-voltage impulses with multiple flash cassettes with leaf base.

The lightning cube according to the innovation is with by high voltage impulse
equipped with ignitable flash lamps and has a square socket pin with a central cylinder bore, which can be rotated at 360 °
four 90 locking positions occupying rotary cylinders with a corresponding square recess and an axially extending, cross-slotted, non-rotating double cone of a lightning cube holder that forms one end of an adapter and the other
The end is designed as a sheet socket fitting into the slot of the flat camera, the electrical conductor tracks of which are electrically conductively connected to the contacts of the BlitzwUrfelfausung.

The base-socket design prevents accidental use of BlitzvUrfeln, equipped with low-resistance lamp type. The adapter is dimensioned in such a way that no "red-eye" effect occurs.

The innovation is explained in more detail using figures:

FIG. 1 shows a ball cube according to the invention in a front view. Figure la shows the innovation according to the lightning cube in a view from below.

FIG. 2 shows the adapter "it de · nouarungsg — MB" n lightning cube assigned version as well as its leaf base design at the kaaeraaeitlgen end in section

FIG. 2a shows the leaf version in top view. Figure 2b shows the blade base end of the ua> $ 0 ° rotated adapter

when inserting into the barrel setting of a Flachkaaera in front view.

Figure 3 shows a flat camera.

On an essentially square base plate 1 (Figures 1, la) four flashlights 2 to be ignited with a high-voltage pulse (10000 - 20OO volts) are arranged. Each flash lamp is a reflector 3 assigned. A radiation-permeable protective cube 4 comprises lamps and reflector. The external power supply lines 5 of the flash lamps are guided downwards through openings in the base plate 1 and bent in a known manner over a ring 6 molded onto the base plate. The base pin, which is common with lightning cubes, is designed as a square 8 with a basic edge length of approximately 9.5 mm and with a central cylinder bore 9 provided with about 6.5 mm clear width.

The lightning cube can be inserted into a socket 10 (Figures 2, 2a), one of them occupies four 90 ° locking positions with a 360 ° rotation Rotary cylinder 11 with matching Viorkant recess 12 and one in this axially extending, cross-slotted, co-rotating, retaining Has double cones 13 made of plastic, with which the square 8 interacts with the cylinder bore 9. The version 1Π forms one end of an adapter l4 that carries the lightning cube, while at the other end it has a blade base 15 (FIGS. 2, 2b) which fits into the slit socket 16 of the flat camera 17 (FIG. 3). the electrical conductor tracks l8 of the blade base 15 are connected to electrical contacts 19 of the socket 10 by means of electrical power supply lines tied together. By turning the lightning cube by hand or using a suitable
