Patent ID: 7849941

Claim:
A universal linkage assembly comprising: a first linkage assembly comprising a first inner cylindrical body and a first outer cylindrical sleeve rotatable about the first inner cylindrical body and the first inner cylindrical body extending through a channel of the first outer cylindrical sleeve and the first inner cylindrical body having a first portion that extends beyond a first end of the first outer cylindrical sleeve and a second portion that extends beyond a second end of the first outer cylindrical sleeve; a first control linkage coupleable to the first outer cylindrical sleeve and to a first joystick to operably connect the first joystick to the first outer cylindrical sleeve to impart a rotational input to the first outer cylindrical sleeve; a second control linkage coupleable to the first inner cylindrical body and a second joystick to impart a rotation to the first inner cylindrical body; a second linkage assembly comprising a second inner cylindrical body and a second outer cylindrical sleeve rotatable about the second inner cylindrical body and the second inner cylindrical body extending through a channel of the second outer cylindrical sleeve and the second inner cylindrical body having a first portion that extends beyond a first end of the second outer cylindrical sleeve and a second portion that extends beyond a second end of the second outer cylindrical sleeve; a third control linkage coupleable to the second outer cylindrical sleeve of the second control linkage assembly and to a first foot pedal to operably connect the first foot pedal to the second outer cylindrical sleeve to impart a rotational input to the second outer cylindrical sleeve; and a fourth control linkage coupleable to the second inner cylindrical body of the second linkage assembly and to a second foot pedal to operably connect the second foot pedal to impart a rotational input to the second inner cylindrical body of the second linkage assembly.
