Abstract
A cover plate is disclosed for a hydraulic control panel that houses a series of manually operable valves for controlling a plurality of hydraulic cylinders associated with an implement such as a backhoe. The cover plate includes a one-piece plastic base with a plurality of upstanding, spaced apart, integral formations along its longitudinal extent through which a plurality of control handles are inserted and attached to the valves. Each formation on the cover plate is generally box-shaped with open sides and aligned openings in its upper and lower walls to permit the passage of a respective control handle through the cover plate. A closed-cell, rectangular block insert is sandwiched within each cover plate formation with an opening therethrough which is aligned with the upper and lower openings in the formation. The cover plate reduces the assembly time and labor required for connecting the control handles to the respective valves within the control panel and provides for self-centering of the control handles to a neutral position.
