Abstract

A device for horizontal and vertical adjustment in geodetic devices comprises within its housing, a horizontal adjusting system comprising a first fine adjustment drive for rotation of the device about a vertical standing axis and a vertical adjusting system comprising a second fine adjustment drive for the movement of a telescope which is mounted in the support of the device so as to be swivelable about a horizontal tilt axis. A coaxial drive, known per se, is arranged at the support of the device and has two coaxially mounted shafts, each having a rotating knob, for initiating the rotation and/or movement of the respective parts and subassemblies. Each of the two fine adjustment gear units comprises a worm and a worm gear with a friction clutch and can be actuated jointly from a location for generating movement in two movement directions running vertical to one another or at an angle to one another. These fine adjustment gear units are arranged in two planes situated at different heights in the housing of the device, wherein the worm of one of these two fine adjustment gear units lies in the plane of the coaxial drive and each worm gear of these two fine adjustment gear units is …
