ABSTRACT:
An instrument support structure having a post vertically telescoped in a column and an interfitted cylinder and rod within the post defining a hydraulic piston connecting the post and the column. A hydraulic reservoir is mounted on the column, is in fluid communication with the piston, and is pressurized so as to exert a force balancing the weight on the post. Pressurization is by air through a common tire valve so that various weights can be selectively balanced. An adjustable fluid valve controls the rate of fluid movement to and from the piston so as to hydraulically lock the post or adjustably control the rate at which a force can reposition the post. A spring biased shoe holds the post against walls in the column, and a threaded lock element enables the shoe pressure to be increased to mechanically lock the parts.
