Tilting supporting device

摘要

A swivel-arm (5) swivels on a horizontal axle (9) and is attached to a base (3). A first powered appliance (13) is linked to the swivel arm. A second arm is supported on a support point (49). A support surface (27) on the swivel base has a displacement pat for the support point. A second powered appliance (36) exerts a counter--force to the upward or downward deflector force (45) onto the end (17) of the first powered appliance linked to the swivel base.
