Abstract
A split grip control lever is suitable for operating heavy machinery and includes a fixed base portion that provides secure operator support during operation of the machine. A movable upper portion is pivotable relative to the fixed base portion by the user's thumb and index finger to control operation of machine components. The movable upper portion and the fixed base portion preferably define a substantially continuous profile. Additionally, a control device is placed inside the fixed base portion of the grip, allowing for a shorter control shaft that pivots at or near the center of the unit. This arrangement facilitates control of the equipment.
Claims17
A split grip control lever comprising:
- a fixed base portion;
- and
- a movable upper portion that is separately pivotable relative to the fixed base portion, wherein the movable upper portion and the fixed base portion define a substantially continuous profile.
A control lever for machinery comprising:
- a fixed based portion fixedly securable to a surface of the machinery;
- and
- a control portion disposed adjacent the fixed base portion and movable relative to the fixed base portion, the control portion being separated from the fixed base portion via a split line and being contiguous with the fixed base portion to define a substantially continuous profile.
A machine comprising:
- a machine frame supporting at least one movable element;
- and
- a control lever secured to the machine frame, the control lever comprising:
- a fixed base portion fixedly secured to the machine frame, and
- a movable upper portion that is separately pivotable relative to the fixed base portion for controlling movement of the at least one movable element, wherein the movable upper portion and the fixed base portion define a substantially continuous profile.
