Claims20
A stand capable of being balanced by way of a balance control system, said stand comprising:
- a base;
- a parallelogram carrier for accommodating a load, said parallelogram carrier comprising at least three support arms, wherein two of said at least three support arms are substantially parallel and supported with respect to said base;
- one of said two parallel support arms having a basic part pivotally attached to said base and a support arm part connected to said basic part;
