Abstract

A joystick for operating heavy machinery. The joystick has a base assembly and a grip assembly wherein a display is integrated into the first end of the grip assembly and the second end is pivotably mounted within the base assembly. Movement of the grip assembly relative to the base assembly moves an actuating assembly of the heavy machinery wherein the display is able to provide useful information to the user during operation.

Claims

1. A joystick for operating heavy machinery comprising:

a base assembly having a first printed circuit board therein;

a grip assembly extending from a first end to a second end that is pivotably connected to the base assembly;

said grip assembly having a second printed circuit board therein wherein movement of the grip assembly relative to the base assembly moves an actuating assembly of the heavy machinery;

a display integrated in a surface of the grip assembly and electrically connected to the first and second printed circuit boards to provide a user with information related to the base assembly and grip assembly;

wherein the grip assembly has a plurality of buttons and the second printed circuit board provides information to the display such that the display displays button status information, button function information, joystick position information and fault and error messages to the user; and

wherein the first printed circuit board provides information to the display such that the display displays joystick position information and fault and error messages to the user provided to the display by the first printed circuit board.

2. The joystick of claim 1 further comprising a control processing unit electrically connected to the display wherein the control processing unit provides information to the display such that the display displays information regarding the heavy machinery including heavy machinery RPM'"'"'s and speed to the user provided to the display by the control processing unit.
