Abstract

The supporting device is constructed as a support stand and contains an upright, a first pivot system pivotably mounted at the upright, a second pivot system rotatably and pivotably mounted at the first pivot system, as well as adjustable counterweights and several pivotable and lockable pivot bearings permitting rotary and pivoting movements. The upright has a substantially U-shaped cross-section containing two side members between which there are arranged, in a space-saving manner, a pivot arm which is pivotably mounted about a substantially horizontal axis, and an L-shaped control lever mounted at the pivot arm and receiving a first counterweight. The second pivot system is arranged at the first pivot system using an L-shaped support arm and is constructed such that the extended horizontal axis of a top lockable pivot bearing intersects with the rotary and pivot axis of a front lockable pivot bearing.
