Abstract
An improved control assembly is disclosed which is particularly suited for embodiment as a so-called mono stick control for a material handling implement. The control assembly includes a lever support member adapted to be pivotally mounted on an associated implement, and which carries a first control lever adapted to pivot with respect to the support member about a first pivot axis. The support member further carries a second control lever which is adapted for pivotal movement about a second axis parallel to and spaced from the first axis. Notably, the second control lever is operatively interconnected with the first control lever such that relatively large angular movement of the second lever results in a relatively lesser angular movement of the first control lever, with the second lever then acting to prevent movement of the first lever back into its neutral position. By this arrangement, a device operatively connected for control with the first lever can be controlled at two rates, thus permitting normal control by manipulation of the first lever, and relatively fine control by manipulation of the second lever.
