ABSTRACT:
An apparatus for counterbalancing equipment incorporating an internal spring counterbalancing mechanism housed inside a hollow vertical column. A pair of arms, pivotally attached to the column, and pivotally attached to a pair of L-brackets on the outer end, form a parallelogram. Equipment such as lights, cameras, industrial or medical devices, can be attached to a mounting platform at the L-brackets. The column is attached to a base equipped with lockable wheels.
Equipment of varying weights can be balanced by connecting a wire from the spring over a pulley, placed on top of the column, to a slidable connection on the parallelogram. By sliding the wire connection along the parallelogram, varying loads can be easily balanced. The hidden, internal spring-balancing mechanism, eliminates the need for cumbersome external counterweights, counter-boom extensions, or sand bags.
The parallelogram can be locked at any position with a clamping mechanism. When used as a camera stand, this feature prevents the camera from moving after the composition and focusing has been accomplished.
