Abstract:
A pivot mounting assembly comprising:a pivot arm for mounting a load in a vertically adjustable manner, said pivot arm being hinged to a pivot base to be pivotable about a horizontal axis, a first force-providing device which is hinged with a first one of its two operative ends to the pivot arm spaced apart from the horizontal axis and which is supported with a second one of its two operative ends on the pivot base at a support location which is vertically spaced apart from the horizontal axis by a distance for providing an antitorque moment to at least partially compensate for a torque imparted by the load on the pivot arm, wherein the pivot base is provided with a support surface which extends transverse to the horizontal direction and has a shift area in which the support location is shiftable along the support surface, wherein the support surface is oriented in the shift area such that, when the support location is disposed in the shift area and the pivot arm is raised, a downwardly directed deflection force acts on the operative end of the first force-providing device supported on the pivot base for shifting the support location, and, when the pivot arm is lowered, an upwardly directed deflection force acts on the operative end of the force-providing device supported on the pivot base for shifting the support location, and a second force-providing device for generating a counterforce to the downwardly or/and upwardly directed deflection force, said counterforce acting on the end of the first force-providing device supported on the pivot base, with the support location being disposed in at least a partial area of the shift area.
