Magnetic control pedal apparatus

In a control pedal apparatus (10) having a frame member (12), magnetic means (52) for generating a control signal in response to an applied magnetic field, said magnetic means (52) having a first (51) and second (53) side and being connected to said frame member (12), and a pedal (14) having a magnet (16) and being movable between a first position at which a magnetic pathway is opened and a second position at which said magnetic pathway is closed, the improvement comprising:

• a movable pedal support (18) having a first elongated member (26), a second elongated member (38) and a base member (20);
• said first elongated member (26) being constructed of magnetically permeable material and having a lower end (28) and an upper end (34), said lower end (28) being rotatably connected to said frame member (12) adjacent said first side (51) of the magnetic means (52);
• said second elongated member (38) being constructed of magnetically permeable material and having a lower end (40) and an upper end (46), said lower end (40) being rotatably connected to said frame member (12) adjacent said second side (53) of the magnetic means (52) and said upper end (46) being spaced-apart from the upper end (34) of said first elongated member (26) and defining a space (49) therebetween;
• said base member (20) being connected to the second end (34,46) of said first and second elongated members (26,38);
• and
• said pedal (14) being pivotally mounted on said base member (20) and movable from said first position to said second position at which said magnet (16) is positioned in said space (49) and said magnetic field is passed between said magnet (16) and said magnetic means (52) by said first and second elongated members (26,38).

Apparatus (10) for controlling the direction and speed of a vehicle, comprising:

• (a) a frame member (12);
• (b) magnetic means (52) for generating a directional control signal in response to an applied magnetic field and being connected to said frame member (12);
