Joystick with additional degree of control
First Claim
Patent Images
1. A joystick, comprising:
- a chassis;
a first potentiometer mounted on the chassis;
a first yoke element mounted on the chassis for pivoting movement about a first axis;
first means for coupling the first potentiometer to the first yoke element;
a second potentiometer mounted on the chassis;
a second yoke element mounted on the chassis for pivoting movement about a second axis that is orthogonal to the first axis;
second means for coupling the second potentiometer to the second yoke element;
a platform member;
means for mounting the platform member on the first yoke element so that the platform member is pivotable about a third axis that is orthogonal to the first axis;
manually operable means for moving the platform member; and
coupling means, extending from the platform member and slidably engaging the second yoke element, for pivoting the second yoke element about the second axis when the platform member pivots about the third axis.

Abstract
A joystick includes a pivotably mounted X yoke connected to an X potentiometer and a pivotably mounted Y yoke connected to a Y potentiometer. To permit at least one additional degree of control, a platform member is pivotably mounted one of the yokes to support an additional control element such as a further potentiometer. The pivoting motion of the platform member with respect to the yoke element on which it is mounted is conveyed to the remaining yoke element. Both a platform member and the remaining yoke element pivot about respective axes that are perpendicular to the pivot axis of the yoke element on which the platform member is mounted.

20. A joystick, comprising:
-
a chassis; a first potentiometer mounted on the chassis; a first yoke element mounted on the chassis for pivoting movement about a first axis; first means for coupling the first potentiometer to the first yoke element; a second potentiometer mounted on the chassis; a second yoke element mounted on the chassis for pivoting movement that is orthogonal to the first axis; second means for coupling the second potentiometer to the second yoke element; a platform member; and an electrical control member mounted on the platform member, the electrical control member having a manually actuable shaft, wherein one of the platform member and the shaft slidably engage the second yoke element to pivot the second yoke element about the second axis when the platform member pivots about the third axis.
