VIDEO CAMERA MOUNTING ASSEMBLY WITH FRICTION BEARINGS

摘要

A fixed-position, but manually adjustable, video camera mounting assembly employs frictional bearing elements (48) in place of ball bearings that are present in a corresponding motor-driven (14) remotely controllable movable mounting assembly (10, 12). The frictional bearing elements (48) are endless toroidal coil springs which provide durability and satisfactory performance over a wide range of temperatures. The endless coil springs (48) are fashioned from linear springs (50) which have an open end (52) and an opposed reduced-diameter end (56) which is pluggable into the open-end.
