Counterbalanced stand for camera

Claim 2

A counterbalanced stand for a gamma camera including a base, an upright stanchion mounted on said base, a generally rectangular frame formed of a pair of spaced parallel beams, means for pivotally mounting a gamma camera between said beams generally adjacent one end thereof, a plate positioned between and fastened to said beams, means for mounting said frame and camera on said stanchion for universal movement of the frame relative to the stanchion including a socket member positioned in said plate, an opening extending through said socket member and having a lower conical portion and an upper cylindrical portion, a cylindrical socket support positioned on the end of said stanchion and extending into said opening with the socket support engaging the portion of the opening defining the conical portion and extending into the cylindrical portion, and a weight mounted to said plate generally adjacent the opposite end of said beams from the camera, and means for adjusting the position of the weight relative to said socket member.

Claim 3

The structure of claim 1 further characterized in that the means for adjusting the position of the weight include a plurality of aligned holes in the plate and a pin extending through the weight and into the holes for adjustably positioning the weight relative to the plate. 3 A counterbalanced stand for a gamma camera including a base, an upright stanchion mounted on said base, a generally rectangular frame formed of a pair of spaced parallel beams, means for pivotally mounting a gamma camera between said beams generally adjacent one end thereof, a weight mounted to said spaced beams generally adjacent the opposite end thereof, a cap at the upper end of said stanchion, an inner gimbal ring pivotally attached to said cap to permit movement of said ring about an axis generally perpendicular to said beams, an outer gimbal ring pivotally attached to said inner ring to permit movement of said outer ring about an axis generally parallel with said beams, and means for pivotally attaching said beams to opposed portions of said outer ring, the means for pivotally attaching the outer gimbal ring to the inner gimbal ring including means for moving the outer ring relative to the inner ring along the pivoTal axis of the outer ring.

Claim 4

The structure of claim 3 further characterized in that the means for pivotally attaching the outer ring to the inner ring include a trunnion and an adjustment screw, generally parallel with each other and aligned along the axis of pivotal movement of the outer ring, rotation of said adjustment screw moving the outer ring relative to the trunnion.
