  • Cylindrical mounting with clearance-free fit
    Patent number: 4738512
    Abstract: The clearance-free fit for cylindrical mountings, in particular photographic lenses, is produced by recesses in the inner wall of a main mounting and projections in the outer wall of an individual mounting, to be fastened in the main mounting by inserting and by a relative rotary movement between the two mountings. The recesses and the projections are of such a configuration that a sufficiently large clearance s is present when the individual mounting is inserted, and this clearance is removed by turning to produce a frictional connection.
