1. A mechanical force multiplier for use in a manually powered vehicle and configured to be mounted to a vehicle frame, comprising:
- a first member pivotally connected to a first point on the vehicle frame;
a second member pivotally connected to a second point on the vehicle frame, wherein the second member is longer than the first member;
a force receiving member operatively connected to the second member and configured to receive a force from an operator positioned on the vehicle frame; and
a rigid section having a first end and a second end, the first end pivotally connected to each of the first and second members, wherein as the force from the operator is applied to the force receiving member, the second end of the rigid section travels in an arcuate path.

Abstract
An improved energy conversion system for propelling a manually powered vehicle is disclosed. The energy conversion system converts the linear kinetic energy applied by an operator to rotational kinetic energy to propel a vehicle. The energy conversion system includes a mechanical stroke multiplier to increase the distance over which the operator may apply a force to the vehicle.

6. A mechanical force multiplier for multiplying a force applied by a human operator seated on a first frame, the mechanical force multiplier comprising:
-
a rigid frame portion having a first end and a second end; a pivoting frame portion having a first end and a second end, wherein the first end of the pivoting frame portion is pivotally connected to the first end of the rigid frame portion and the second end of the pivoting frame portion is pivotally connected to the first frame; a force receiving member mounted to the pivoting frame and configured to receive the force applied by the human operator, wherein the first end of the pivoting frame portion travels a first distance responsive to the force applied by the human operator and the second end of the rigid frame portion travels a second distance responsive to the force applied by the human operator and wherein the second distance is greater than the first distance. - View Dependent Claims (7, 8, 9, 10, 11)
