Steering and transmission shifting control device
First Claim
1. A steering and transmission shifting control mechanism for operating a vehicle having a reversible multi-speed transmission for moving the vehicle in forward and reverse directions at different speed ratios, comprising:
- a steering wheel having a front portion defining a front surface facing an operator and a back portion defining a back surface facing away from the operator;
support means for mounting the steering wheel on the vehicle for rotatable movement by movement of an operator'"'"'s hand;
means responsive to the rotatable movement of the steering wheel for steering the vehicle;
means for changing the speed ratio of the transmission of the vehicle including at least one control button mounted on the front portion of the steering wheel and extending from the front surface so that the control button may be conveniently controlled by an operator'"'"'s thumb; and
means for selecting either the forward or reverse drive condition of the transmission including a control trigger, the control trigger being a three-position switch mounted on the back portion of the steering wheel and extending from the back surface so that the control trigger may be conveniently controlled by an operator'"'"'s finger.

Abstract
The design and manufacture of past steering and transmission shifting control devices utilized an upright and rockable control handle for the steering function and an actuating element in close association with the control handle for effecting a speed change function of a multi-speed transmission. The design of the control handle does not offer a rotatable steering member which is familiar and easy to operate. The present invention overcomes these problems by providing a steering wheel for steering a vehicle. A means for changing the speed ratio of the transmission is mounted on a front portion of the steering wheel and extends from a front surface so that the changing means may be conveniently accessed by an operator. A means for selecting either the forward or reverse drive condition of the transmission is mounted on the back portion of the steering wheel and extends from the back surface so that the selecting means may be conveniently accessed by the operator. The use of the steering wheel results in a convenient and simple steering and transmission shifting control device.
