Abstract
Abstract A single control stick for a motor-driven vehicle with wheels pivotally mounted on a locating means for movement in two planes of movement, a first plane of movement along the longitudinal axis to provide accelerating action or braking action, a second plane of movement normal to the first plane for steering action which is done by braking the wheels separately.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
280 words
A control stick system for use in association with a motor driven vehicle having driven wheels on each side and separate brake means for said driven wheels on each side and joint brake operating means for braking said vehicle and selective braking operating means for steering the same, and motor speed control means for controlling the speed of said vehicle, said control system comprising: movable control stick mounting means adapted to be secured in said vehicle and supporting said control stick for swinging from side to side with respect to an intermediate central position in a first plane of movement, transversely of said vehicle; a control stick pivotally mounted on said mounting means for swinging forward and rearward with respect to an intermediate neutral position in a second plane of movement arranged and oriented to be parallel to the longitudinal axis of said vehicle; joint brake operating connection means adapted to be connected to said joint brake operating means and operatively connected to said control stick and responsive to movement thereof in one direction away from said neutral position in said second plane to operate said brakes in unison; selective brake-operating connection means adapted to be connected to said selective brake operating means and operatively connected to said control stick and responsive to transverse movement thereof away from said central position in said first plane to operate a respective one of said brake means selectively, and, motor speed control connection means adapted to be connected to said motor speed control means and operatively connected to said control stick and responsive to movement thereof in said second plane in the opposite direction away from said neutral position to accelerate said motor.
Claim 2
Dependent Claim
280 words
A control stick system for use in association with a motor driven vehicle having driven wheels on each side and separate brake means for said driven wheels on each side and joint brake operating means for braking said vehicle and selective braking operating means for steering the same, and motor speed control means for controlling the speed of said vehicle, said control system comprising: movable control stick mounting means adapted to be secured in said vehicle and supporting said control stick for swinging from side to side with respect to an intermediate central position in a first plane of movement, transversely of said vehicle; a control stick pivotally mounted on said mounting means for swinging forward and rearward with respect to an intermediate neutral position in a second plane of movement arranged and oriented to be parallel to the longitudinal axis of said vehicle; joint brake operating connection means adapted to be connected to said joint brake operating means and operatively connected to said control stick and responsive to movement thereof in one direction away from said neutral position in said second plane to operate said brakes in unison; selective brake-operating connection means adapted to be connected to said selective brake operating means and operatively connected to said control stick and responsive to transverse movement thereof away from said central position in said first plane to operate a respective one of said brake means selectively, and, motor speed control connection means adapted to be connected to said motor speed control means and operatively connected to said control stick and responsive to movement thereof in said second plane in the opposite direction away from said neutral position to accelerate said motor.
Claim 3
Dependent Claim
40 words
The control system, as described in claim 1, wherein control stick movement in said second plane of movement for braking or accelerating action may occur while said control stick is being swung in said first plane of movement for steering.
Claim 4
Dependent Claim
46 words
The control system, as described in claim 1, including a releasable control stick positional locking means on said mounting means operatively associated with said control stick to engage and lock the same in at least one predetermined position in said first plane of control stick movement.
Claim 5
Dependent Claim
42 words
The control system, as described in claim 3, including return spring means connected to said joint and selective brake operating connection means and operatively connected to said control stick to urge said control stick towards said neutral position in said second plane.
Claim 6
Dependent Claim
180 words
The control system as claimed in claIm 3 wherein said releaseable control stick positional locking means includes a locking plate member attached to said selective brake-operating means, attachment bracket means fastened to the lower end of said control stick, and pivotally mounted on said locking plate member for swinging to and fro in said second plane of movement, locking detent means on said locking plate in predetermined orientation in relation to the forward and rearward position of said control stick, a locking member movably mounted on said support bracket means, and releaseably interengageable therewith, while said control stick is moved in said second plane away from said neutral position in the direction of movement thereof corresponding to operation of said joint brake operating means, movement of said control stick in said second plane, in said opposite direction away from said neutral position, being free of interlocking engagement between said detent and said locking member, and manually operable locking member release means arranged at the upper end of said control stick for manually releasing said locking member from said detent means.
Claim 7
Dependent Claim
54 words
The control system as claimed in claim 5 including resilient biassing means engaging said locking member and operatively urging said locking member into engagement with said detent means, said manually operable release means being arranged to be operable to overcome said biassing means and release said locking means from said detent means as aforesaid.
Claim 8
Dependent Claim
59 words
A control system as claimed in claim 1 wherein said control stick mounting means includes a shaft member arranged parallel to the longitudinal axis of the vehicle, bearing means rotatably mounting said shaft member therein, mounting plate means on said shaft member, and control stick pivot means on said mounting plate means, said control stick being pivotally connected thereto.
Claim 9
Dependent Claim
81 words
A control system as claimed in claim 7 wherein said control stick includes pivot plate means adjacent one end thereof, the other end of said stick being free to be grasped by an operator, said pivot plate means being shaped and oriented to engage said mounting plate means on said shaft member to transmit transverse swinging of said stick in said first plane and causing semirotary movement of said shaft member and being pivotally connected to said pivot means as aforesaid.
Claim 10
Dependent Claim
57 words
A control system as claimed in claim 8 wherein said joint brake operating connection means includes brake control rod means having one end connected to said pivot plate means for movement in unison therewith in response to swinging of said stick in said second plane, and having its other end connected to said joint brake operating means.
Claim 11
Dependent Claim
35 words
A control system as claimed in claim 7 wherein said selective brake operating connection means include yoke means mounted on said shaft member and extending on either side thereof for semirotary movement in unison therewith.
