Abstract
Abstract An eight-way joystick control system is disclosed. The joystick comprises a control shaft having a handle end adapted for grasping and deflection of the control shaft by a user, and pivot defining a fixed point about which the control shaft is deflected at the handle end by the user. The control shaft has a central neutral position and eight control sector positions spaced radially around the neutral position. An indicator is included that produces a distinctive electrical signal when the control shaft is in each of the control sector positions. A control structure defines a deflection limit of the control shaft in an octagon shaped deflection pattern with eight corners. Each corner corresponds to one of the eight control sector positions such that when the control shaft is deflected into any one of the eight corners the control shaft is positioned in the corresponding control sector position. The control structure provides for a smooth unimpeded deflection limit between the corners, and provides a stop for tactile feedback to the user indicating that the control shaft is in the control sector position corresponding to a corner.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
215 words
Joy-stick control system comprising an eight-way joystick and a control structure, the joystick being fully functional as an eight-way joy-stick without the control structure and comprising: control shaft having a handle end adapted for grasping and deflection of the control shaft by a user, pivot defining a fixed point about which the control shaft is deflected at the handle end by the user, the control shaft having a central neutral position and eight control sector positions spaced radially around the neutral position, indicator that produces a distinctive electrical signal when the control shaft is in each of the control sector positions, the control structure releasably attached to the joystick, the control structure defining a deflection limit of the control shaft in an octagon shaped deflection pattern with eight corners, each of the corners corresponding to one of the eight control sector positions such that when the control shaft is deflected into any one of the eight corners the control shaft is positioned in the corresponding control sector position, the control structure providing a smooth structure for unimpeded movement of the control shaft along the deflection limit between the corners with each of the corners providing tactile feedback to the user indicating that the control shaft is in the control sector position corresponding to the corner.
Claim 2
Dependent Claim
