In-line racing skate propulsion device
First Claim
1. An in-line roller skate propulsion device comprising:
- a wheel frame having a left side plate and a right side plate;
each of the left and right side plates having a top, a bottom, a plurality of wheel axle holes near the bottom, and a pivot means near the top for pivotally connecting a lever to the wheel frame;
the wheel frame also having a means for connecting a resilient member;
a lever having a pivot means for pivotally connecting the lever to the wheel frame located forward of the center of the lever, a means for connecting a resilient member to the lever, and a means for connecting a boot to the lever;
wherein the pivot means of the left and right side plates pivotally connect the lever to the wheel frame in a fixed translation position with respect to the wheel frame;
a resilient member;
the device having a zero position;
the resilient member always being under tension so as to maintain the device in the zero position or return the device from a rotated position to the zero position; and
wherein the wheel frame'"'"'s means for connecting the resilient member is more rearward of the device than the lever'"'"'s means for connecting the resilient member when the device is in the zero position.

Abstract
An in-line roller skate propulsion device comprising a lever and a wheel frame having a top, a bottom, a plurality of wheel axle holes near the bottom, a pivot connection near the top for pivotally connecting the lever to the wheel frame, and a hole and shaft combination for connecting a resilient member. The lever'"'"'s pivot connection is located forward of the center of the lever. As the lever rotates around its pivotal connection to the wheel frame, the resilient member is stretched. Upon release of the rotating force, the resilient member returns the lever to a point of contact with the wheel frame or a stopping piece attached thereto. This action allows a skater to achieve greater speeds than with regular in-line roller skates while exerting the same amount of energy.
