VIDEO CAMERA MOUNTING ASSEMBLY WITH FRICTION BEARINGS

摘要

A fixed-position, but manually adjustable, video camera mounting assembly employs frictional bearing elements in place of ball bearings that are present in a corresponding motor-driven remotely controllable movable mounting assembly. The frictional bearing elements are endless toroidal coil springs which provide durability and satisfactory performance over a wide range of temperatures. The endless coil springs are fashioned from linear springs which have an open end and an opposed reduced-diameter end which is pluggable into the open end.
