Counterweight arrangement for spatially adjustable medical X=ray appts.

摘要

The X-ray sighting equipment is mounted on a pedestal in a plane parallel to the examination table and can be raised and lowered on a column. The counter wt. carries the wt. of the equipment at the end of a first lever rotatable about a fixed point on a vertical spindle. A second lever has one end adjustable along the spindle and is spring-loaded so that this end moves up and down as the equipment is tilted, to reduce the component of wt. on the carriage (16).
