Abstract

A pivot mechanism for a housing laterally arranged at a support, such as a stand or the like, especially a housing for a medical instrument, comprising a first axle body and a second axle body, the second axle body being rotatably mounted at one side or end in the first axle body and at the other side or end is capable of being operatively connected with the housing. The first axle body and the second axle body are mounted in a headpiece such that the housing is horizontally rotatable about an essentially vertical lengthwise axis of the first axle body and vertically pivotable about an essentially horizontal lengthwise axis of the second axle body. The headpiece has at least one friction surface for the horizontal rotational movement and further friction surfaces for the vertical pivotal movement. For braking such movements there is provided but a single resilient element such as a compression or pressure spring.
