Abstract

An energy conversion system that converts linear kinetic energy to rotational kinetic energy is disclosed. A force is applied to a coil spring, compressing the spring. The spring drives an arm forward as the spring returns to its uncompressed state. The arm, in turn, causes the driving portion of an over-running clutch to rotate forward and drive an output shaft. The linear motion of the arm being driven forward by the spring is converted to rotational kinetic energy in the output shaft. The output shaft may then be connected to an external device to drive that device.

Claims

1. An energy conversion system, comprising:

a frame;

a spring compression system, further comprising;

a plate operably mounted to the frame for receiving a generally linear force to move between a retracted position and an extended position,

a transfer bar having a first end and a second end, the first end of the transfer bar connected to the plate and movable between the retracted position and the extended position, and

a lever pivotally mounted to the frame and having a first end and a second end, the first end of the lever connected to the second end of the transfer bar;

a push arm having a first end and a second end, the first end of the push arm is engaged by the second end of the lever;

a coil spring having a first end and a second end, the first end of the coil spring engaged by the push arm, wherein the coil spring is compressed by the lever engaging the push arm when the plate is in the extended position;

a transfer member including a first portion with an opening extending therethrough and a second portion extending away from the first portion, wherein the second end of the push arm engages the second portion of the transfer member;

an over-running clutch having a driving portion and a driven portion, wherein the opening on the transfer member engages the driving portion; and

an output shaft connected to the driven portion of the over-running clutch, wherein the over-running clutch engages the output shaft when the transfer member rotates faster than the output shaft and the clutch disengages the output shaft when the transfer member rotates slower than the output shaft.

2. The energy conversion system of claim 1 further comprising a second spring compression system, wherein the first end of the push arm is engaged by the second end of each of the levers.

3. The energy conversion system of claim 1 further comprising a flywheel mounted on the output shaft.

4. The energy conversion system of claim 1 wherein the push arm has an upper surface including one or more cavities and further comprising a holding arm operably connected to the frame to selectively engage the cavity on the upper surface of the push arm.

5. The energy conversion system of claim 4 wherein the push arm has at least two cavities and wherein the holding arm sequentially engages each of the two cavities on subsequent cycles of the plate between the retracted and extended positions.

6. The energy conversion system of claim 5 further comprising:

a spacer block selectively positioned between a first position and a second position, wherein the spacer block is removed from a space defined between the second end of the lever and the first end of the push arm in the first position and the spacer block is within the space defined between the second end of the lever and the first end of the push arm in the second position.

7. The energy conversion system of claim 1 wherein the second end of the push arm is directly connected to the second portion of the transfer member.

8. The energy conversion system of claim 1 further comprising:

a drive bar having a first end and a second end, the first end of the drive bar pivotally connected to the frame and the second end of the push arm is connected near the first end of the drive bar;

a linkage rigidly connected proximate to the second end of the drive bar having an opening defined, at least in part, by the linkage; and

a return bar having a first end and a second end, wherein the second end slidably engages the opening in the linkage and the first end is connected to the second portion of the transfer member.

9. The energy conversion system of claim 8 wherein the drive bar has a plurality of holes extending from the first end of the drive bar along a portion of the length of the drive bar and wherein the second end of the push arm is selectively connected to one of the holes.

10. The energy conversion system of claim 1 wherein the output shaft is connected to one of a wheel, a pump, and a generator.

11. An energy conversion system for converting linear kinetic energy into rotational kinetic energy, comprising:

a frame;

a spring compression system, further comprising;

a plate operably mounted to the frame for receiving a generally linear force to move between a retracted position and an extended position,

a transfer bar having a first end and a second end, the first end of the transfer bar connected to the plate and movable between the retracted position and the extended position, and

a lever pivotally mounted to the frame and having a first end and a second end, the first end of the lever connected to the second end of the transfer bar;

a coil spring having a first end and a second end, the second end of the coil spring rigidly connected to the frame;

a compression plate having a first surface mounted to the first end of the coil spring, wherein the compression plate is engaged by the second end of the lever to apply a compressing force against the coil spring when the plate travels from the retracted to the extended position;

a push arm having a first end and a second end, the first end of the push arm is connected to the compression plate;

a drive bar having a first end and a second end, the first end of the drive bar pivotally connected to the frame and having a plurality of holes extending from the first end of the drive bar along a portion of the length, wherein the second end of the push arm is selectively connected to one of the holes;

a linkage connected proximate the second end of the drive bar having a channel formed along one side of the linkage;

a return bar having a first end and a second end, wherein the second end slidably engages the channel in the linkage;

a transfer member including a first portion with an opening extending therethrough and a second portion extending away from the first portion, wherein the second portion of the transfer member is connected to the first end of the return bar;

an over-running clutch having a driving portion and a driven portion, wherein the opening on the transfer member engages the driving portion; and

an output shaft connected to the driven portion of the over-running clutch, wherein the over-running clutch engages the output shaft when the transfer member rotates faster than the output shaft and the clutch disengages the output shaft when the transfer member rotates slower than the output shaft.
