Abstract

See full text

A focusing mechanism for a binocular with dual stiffness of operation, comprises a focusing knob which is mounted rotatably about its longitudinal axis on a static shaft which is fixedly mounted in the binocular structure. The focusing knob is associated with a braking means with adjustable braking effect and is provided with a braking drum. The cylindrical circumferential surface of the braking drum is associated rotatably about its longitudinal axis with the cylindrical circumferential surface of a braking ring, whose other cylindrical circumferential surface is associated by its circumferential surface with a collet of a clamping ring, which is with its rigid part seated in the housing which is fixedly mounted on the static shaft. The collet of the clamping ring is associated with the control of the pressure force on the cylindrical circumferential surface of the braking ring, the control of the gripping of the collet being coupled to a switch of stiffness of the focusing operation.
