Jun 21, 2004

Appl. No.:

10/874134

Inventors:

Jeffrey Eaton Cole - Danville CA, US

International Classification:

B60M 1/00

US Classification:

280 87042, 280 8701, 180181

Abstract:

An occupant propelled device having at least one hydraulic cylinder, a platform and a housing. The at least one hydraulic cylinder has at least two chambers in fluid communication. The platform is attachable to the at least one hydraulic cylinder, such that upon movement of the platform a hydraulic fluid is displaced from one chamber to the other chamber. The housing is attachable to the platform at a pivot point and has at least one axle adapted to receive at least one wheel.

Jeffrey Cole - Danville CA, US

International Classification:

A63C 17/02
A63C 1/24

US Classification:

280 87042, 280 1128, 280 11204

Abstract:

A steering enhancement and braking system for a skateboard or wheeled platform having an actuating element configured to change the position of the skateboard deck relative to the skateboard truck. The actuating element comprises a deck plate configured to be attachable to a skateboard deck, and a truck plate configured to be attachable to a skateboard truck and the deck plate. Upon an application of a force to the skateboard deck the position of the truck plate relative to the deck plate changes. In addition, the system can achieve braking action by transferring the differential motion to the skateboard deck and the truck by the use of the actuating element.

F16D 31/02

US Classification:

280 4323, 280 87042, 60450

Abstract:

A device for generating rotational energy for hydraulic fluids, which includes at least one hydraulic cylinder, the at least one hydraulic cylinder comprising at least two chambers, wherein each of the at least two chambers are in fluid communication with the other. The hydraulic fluid is displaced from the hydraulic cylinder to an accumulator and a valve, which controls the release of the hydraulic fluid to a hydraulic motor. The hydraulic motor receives the hydraulic fluid from the accumulator and valve creating torque to drive a wheel or other device.

International Classification:

A63C 1/00

US Classification:

280 1127, 280 1128, 280 87042

Abstract:

A truck assembly for a skateboard having an inner ring adapted to be attachable to a skateboard deck, and an outer ring adapted to be attachable to an axle extending from the outer ring, wherein the axle is configured to receive at least one wheel. The inner ring and the outer ring rotate relative to one another upon a change in an orientation of the skateboard deck.

Abstract:

A method of propelling a wheeled platform, which includes creating a source of energy upon a first change in orientation of the platform around an axis approximately parallel to a longitudinal axis of the platform and wherein the platform rotates around the axis. The source of energy is stored and released to propel the wheeled platform upon a second change in orientation of the platform around the axis.
