Cursor controller having cross-translating platforms with a cantilevered handle
First Claim
1. A cursor controller for use with a computer having a grippable handle movable in X axis and Y axis directions, which are orthogonal including X and Y linear motion detectors to control the movement of a computer generated cursor in response to movement of the handle comprising:
- a lower fixed base on which is mounted in the Y direction at least one portion of said Y motion detector, and including one part of a male-female pair of Y interlocking guide means fixed on the top face of said base in an elongated Y direction;
an intermediate slab-like platform, on which is mounted in the X direction at least one portion of said X motion detector, and having the other part of said Y interlocking guide means on its bottom face and slidable only in the Y direction on said fixed base for a predetermined Y distance, said intermediate platform having one part of a male-female pair of X interlocking guide means fixed on its top face in an elongated X direction;
an upper slab-like platform having the other part of said X interlocking guide means on its bottom face and slidable only in the X direction on said intermediate platform for a predetermined X distance;
a rigid cover having a top face and sides which securely fit to the sides of said lower fixed base to retain said intermediate and upper platforms in slidable engagement with each other and said fixed base, said top face having a work surface with said X and Y predetermined dimensions;
said upper platform including bracket means, having two ends, for cantilevering over the top face of said cover from a Y direction extremity of said upper platform, to which a said end is fixed, the other said end carrying said handle, said grippable handle having a Z axis which substantially intersects the effective center of said X interlocking guide means, said handle being freely movable over said work surface by the sliding of said intermediate and upper platforms.

Abstract
A cursor controller with a handle which moves in X, Y directions has the handle cantilevered on a upper platform which slides on an intermediate platform in an X direction with the axis of the handle intersecting the effective center of X guide means. And then the intermediate platform slides on a Y guide on a lower fixed platform, all of the foregoing being captured by a top cover. The top cover has a slot through which the handle, which is cantilevered on a bracket fixed to the end of the top platform, extends. The controller can be mounted directly on a keyboard or with a specially shaped enclosure to be operated by one hand.
