Unitary pedal apparatus for selectively accelerating and braking a vehicle
First Claim
1. A unitary pedal apparatus for selectively accelerating and braking a vehicle comprising:
- a. a pedal;
b. a normally closed pedal switch, being integral with said pedal and responsive to open upon the application of slight pressure on said pedal;
c. a pedal arm with said pedal affixed to one end thereof;
d. a shaft with the other end of said pedal arm affixed thereto;
e. a lever secured to said shaft;
f. an expandable mechanical linkage element attached to said lever to absorb any overstressing of the mechanical linkage;
g. a crank bar connected to said expandable element;
h. a solenoid fixedly attached to said crank bar, said solenoid including a one-way clutching means, said solenoid having a longitudinal aperture therethrough;
i. a rod protruding through said aperture of said solenoid, said rod being secured to the throttle of the vehicle;
j. a brake bar abutting said arm and responsive to sufficient movement of said arm to actuate the master cylinder of the vehicle for braking;
k. a battery lead electrically connecting the vehicle battery to the positive side of said pedal switch; and
l. a pedal lead electrically connecting the negative side of pedal switch to said solenoid which allows said solenoid to be energized when said pedal switch is closed.

Abstract
A unitary pedal apparatus for selectively accelerating and braking a motor vehicle in which depressing the pedal actuates the master cylinder for braking and subsequent lessening of pedal pressure effects acceleration, the apparatus including a switch within the pedal for placing the throttle at idle position and another switch in response to braking of the vehicle which places the throttle in the idle position, both switches when closed effecting energization of a solenoid located adjacent the throttle bar in the linkage arrangement, the linkage arrangement including a lost motion device which is expandable to prevent deformation of the linkage in response to hard braking.
