Two-blade lock

innovation
The £ «> £ 4ndu» 8 refers to a photographic two-leaf shutter, in particular with a large shutter opening and short shutter times.

The area of application of the two-blade shutters is predominantly in cameras with small shutter openings. With closures of this type, which are equipped with two steel lamellas, closure times of up to 1/500 sec measured. With simple closures with two steel lamellas and a large opening it is not possible to have such short ones To achieve shutter speeds.

It is known to increase the shutter speeds by moving parts such as slats, curtains or

Sole blinds held in photographic shutters Sheet steel, a specifically lighter material, is used. So 1 211 068 from the German Auslegesohrift • Known in processes for the production of material suitable for Versohlußlamellen, with thin Alumlniumbleohe be applied on both sides of a thin titanium sheet

From the German utility model 1 482 389 “in Objekt iwersohluB is known, whose Versehlufi leaves are made of light metal.

The task of the innovation is with a camera with a Two-lamellae closure and especially with a large ver short opening to achieve spilling times

This task is nowadays solved by the fact that the Slats are made of different materials » where dl «base lamella has an outer shape that dl · Occlusion barely covers

By choosing a light material for the sole floating lamella, it is possible that this after approval «through the magnet armature and driven by the HachfUhrfeder immediately experienced a high acceleration and with the Closing of the shutter opening begins

According to the innovation, welter “combinations when putting together the materials for the two slats” are the Opening lamella and the SehlieBlaaelle possible. 80 canoe the steel opening lamella and the closing lamella Aluminum, plastic or titanium. The opening lamella can, however, also be made of titanium and the lamella are made of aluminum or plastic.

Based on the drawing that shows the execution fog Locking device is in perspective position, let the invention be described below.
