Abstract

A steering mechanism for a vehicle having a steering shaft includes an elongated crank having a first end operably fixedly connected to an end of the steering shaft and a steering plate rotatably connected to a second end of the elongated crank and having a pair of laterally displaced handles connected thereto, such that the steering plate is rotatable about the steering shaft and may further include at least one idler crank having a first end rotatably connected to a portion of the vehicle and a second end rotatably connected to the steering plate.

Claims

1. A steering mechanism for a vehicle, which includes:

a steering shaft having a male splined end;

an elongated crank having a first female splined end operably matably splined to said splined end of said shaft;

a steering plate rotatably connected to a second end of said crank and having a pair of laterally displaced handle grips connected thereto, such that said plate is rotatable about said steering shaft causing said shaft to rotate; and

means for maintaining said handle grips in a fixed non rotating position with respect to one another when said plate is rotated about said shaft wherein said maintaining means includes at least one idler crank having a first end rotatably connectable the vehicle and a second end rotatably connected to said steering plate.

2. The steering mechanism of claim 1, wherein said handle grips are fixedly connected to said steering plate.

3. The steering mechanism of claim 1, wherein said maintaining means includes a mounting plate connectable to the vehicle disposed adjacent the steering shaft and includes at least one idler crank having a first end rotatably connected to said mounting plate and a second end rotatably connected to said steering plate.

4. The steering mechanism of claim 1, which further includes a housing disposed about said crank and said steering plate and having an open surface through which said handle grips can be operably accessed.
