Abstract
An electromechanically driven digital indicating device comprising an arrangement of seven flaps electromagnetically movable to one of two defined positions. The flaps are disposed in a housing at one plane thereof so as to form an "8"-shaped figure. The device includes a deep drawn parallelopiped housing having a front window opening in the form of a parallelogram and having a plate with an elevated, freely accessible "8"-shaped contour constructed integrally with the housing. The plate is supported only at connecting rods at the rear of the housing in internal sides walls of the housing. On the reverse side of the bar-shaped contour, there are provided grooves into which bearing bolts of the flap elements are pivotally inserted.

An electromechanically driven digital indicating device comprising:
- a deep drawn parallelopiped housing having a front window opening in the shape of a parallelogram, said housing having internal side walls and bearing a plate with an elevated, freely accessible, bar-formed, "8"-shaped contour, said plate being constructed integral with the housing with a space between and plate and said housing, said housing including connecting rods and wherein said plate is supported only at said connecting rods at the rear of said internal side walls;
- an arrangement of seven flap elements for movement between two defined positions, said flap elements representing, at one plane of said housing, in composite, an "8" shape, said flap elements being disposed on said housing and cooperating with said contour;
- electromechanical means for controlling movement of the flap elements so that when combinations of certain of the flap elements are actuated thereby, representations of digits are shown;
- and
- wherein, at the reverse side of the elevated contour, grooves are disposed, into which said flap elements are pivotally insertable, and wherein bearing bolts are employed to support said flap elements.

- electromechanical means for controlling movement of the flap elements so that when combinations of certain of the flap elements are actuated thereby, representations of digits are shown through said space;
- wherein, at the reverse side of the elevated contour, grooves are disposed, into which flap elements are pivotally insertable, and wherein bearing bolts are employed to support said flap elements;
- wherein, at the bar-shaped contour on the reverse side as part of the housing, there are at least two of said bearing bolts for fastening for each said flap element upon which an electromagnet means if fixable at a correct position to drive the flap elements;
- and
- wherein each electromagnet means has a coil body which, at its one end in the direction of the coil axis, is provided with a U-shaped profile with flange-shaped externally projecting lugs and bearing holes in the lugs the coil body of the electromagnet means being fastened to the bearing bolts at the reverse side of the bar-shaped contour so as to secure the bearing bolts of the flap elements in the grooves.
