The invention relates to a multiple unit and in particular a flash cube equipped with four mechanically ignitable flash lamps. There are already lightning cubes with mechanically ignitable Blitzlarapen known, which are similar to the previously common lightning cube with electrically ignitable flash lamps, constructed. A translucent protective cube surrounds a quadruple reflector, the sits on a gruid plate on which four flash lamps are mounted. Vm the nechan • ches Schlagw

Various types of impact mechanism are already known, all of which are based on the principle of holding a resilient element in a pre-tensioned position, then releasing it from its pre-tensioned position by means of an outlet element coming from the camera and thus causing the flash lamp to ignite, since the resilient element from its preloaded into its rest position and hits the detonator. ⁿ he hitherto known striking mechanisms are designed as torsion springs which have the shape of a U-shaped bracket, on the open side of which one end is bent like a hook only fastening in the base and the other end is designed as a striking arm, which in a Plane is stretched perpendicular to the U-shaped bracket. The U-shaped brackets of the torsion springs are attached in the middle of the base plate and protrude almost to the top surface of the protective cube in the free space between the four reflectors. In the previous reflectors for flash cubes with electrically ignitable flash lamps, the space in between to accommodate four such brackets is too small and a new, enlarged reflector shape for the flash cubes with mechanically ignitable flash lamps is therefore essential.

To reduce tool costs, increase profitability of the Tools due to increased quantities and to simplify storage || attitude would be the retention of the reflector size and shape of the lightning cube with electrically ignitable flash lamps for the flash cubes with mechanically ignitable flash lamps of great advantage. It is therefore necessary to find a striking mechanism for a flash cube with mechanically ignitable flash lamps, which on the one hand allows the retention of the previous reflector size allows and on the other hand in the same way can be triggered by the camera, like the previously known striking mechanisms.

A multiple flash device, in particular a Lightning cube, proposed, consisting of a transparent protective

cube, which surrounds a quadruple reflector, which sits on a base plate in which four mechanically ignitable flash lamps are mounted, and the four _; Has openings which serve as a passage for the ignition trigger pin coming from the camera, characterized in that a striking mechanism in the form of a bending spring is provided for each flash lamp, which is arranged in each corner of the base plate on a pin provided for this purpose. The spring consists of a few turns and a hook-shaped protruding end, which holds the second end, designed as an impact arm, in a pretensioned position. The base plate is designed in such a way that a pin is arranged in the corners which cannot be used for the active reflector surface, which pin is surrounded by a groove which corresponds to the outline of the flexure spring and serves as a receptacle for the same.

One embodiment of the multiple flash device according to the invention described with reference to the following figures.

Figure 1 shows a lightning cube in a perspective exploded drawing.

FIG. 2 shows a bending spring mounted in the base plate in FIG the top view.

FIG. 3 shows the built-in flexure spring according to FIG. 2 in a side view.

The lightning cube shown in Figure 1 consists of the transparent protective cube (1) that surrounds the quadruple reflector (2). Reflector and Protection cube sit on the base plate (3) »for this purpose with a Paragraph (4) is provided. The base plate (3) is preferably used as a spray, cast part made of plastic and has four blind bores (5), which are used to hold the tubes (7) protruding from the mechanically ignitable flash lamp (6). In the tube (7) is a primer which can be ignited by shock and which in the lightning

In addition, four openings (8) in the form of partial annular grooves are arranged in the base plate, which serve as a passage opening for the release pin coming from the camera. In the corners of the Baaisplatte (3) pins (?) Are cast on, on which the flexible booms (10) sit. The pins tstna have a bevel to make it easier for the flexion springs to be pushed on.
