Holding arrangement having a weight balance
A holding arrangement is suitable especially for medical-optical equipment ( 108 ). The holding arrangement includes a carrier arm ( 101 ) for accommodating a load. The carrier arm ( 101 ) is pivotally mounted on a holder ( 102 ) with the aid of a first rotational joint ( 103 ). The holding arrangement further includes a linear spring arrangement ( 120 ) for generating a longitudinal force which acts upon the carrier arm ( 101 ) in order to compensate a load torque arising in the first rotational joint ( 103 ) of the carrier arm ( 101 ). The linear spring arrangement ( 120 ) for generating a longitudinal force is pivotally mounted on the holder ( 102 ) and applies a force on a curved carrier ( 119 ) which is operatively connected to the carrier arm ( 101 ).
