  • Publication number: 20150028557
    Abstract: The present invention reduces or eliminates suspension induced lower portion chain grow for rear derailer equipped bicycle drive trains using a pivoting mount for the common chain guide pulley. Attached about or near concentric with the chain ring and bottom bracket this mounting plate has a pivotally connected link to the suspension. The chain guide pulley is positioned to “take-up” or store some lower portion of chain length around the chain ring. Suspension activation creates pivotal movement of the guide mounting plate to relieve suspension induced chain grow by releasing some or the entire taken-up length of the lower portion of the drive chain.

  • Publication number: 20140265217
    Abstract: A novel transmission for cycles that significantly reduces torque interference with steering operations is provided. Such a transmission allows for improved recumbent cycling capabilities. The inventive device thus includes a combination of a fixed transmission assembly that reduces torque levels and a movable transmission assembly that multiplies torque levels, allowing for the avoidance of high torque effects through the vehicle's steering axis. As such, the capability of the overall cycle device to steer properly and to a rather wide angle from center while implementing such a torque transfer protocol allows for a unique recumbent cycle configuration. Such a device, then, may be utilized for a human-powered cycle vehicle or one that further includes an electrical component to allow for automated drive capabilities through a rear wheel or wheels, as well. The method of implementation of such a transmission within a variety of cycle devices is also encompassed within this invention.

  • Publication number: 20110095505
    Abstract: An exercise vehicle is provided with an improved push/pull rod steering system for use in directing vehicle travel and maintaining balance without interfering significantly with vehicle power. The vehicle includes a frame with an attached drive system that includes a drive wheel. The drive system includes arm levers operatively connected to the drive wheel so that counter-reciprocal movement of the arm levers produces rotation of the drive wheel. The steering system includes a guidance wheel rotatively coupled with the frame, a steering crank which is operatively coupled with the guidance wheel, hand levers pivotally attached to the arm levers and push/pull rod assemblies connecting the hand levers to the steering crank. When one hand lever pivots, the steering crank rotates, causing the guidance wheel to turn while simultaneously causing the other hand lever to pivot the opposite direction.

  • Publication number: 20100308556
    Abstract: This invention relates to the drive technique of bicycles, particularly two-wheel and rear-wheel driven ones. This invention comprises a front-wheel driver unit which moves rectilinearly and directly matches the front-wheel ratchet wheel, to drive the front wheel. It also contains a curvilinear rear-wheel driver unit which moves along a curve and directly matches the rear-wheel ratchet wheel to drive the rear wheel. The two-wheel driven bicycle has a head tube in the front to form a bracket to support the cyclist's shoulders so that the cyclist, while using his or her arms to steer the bicycle and drive the front wheel, does not have to make big effort to support his/her upper body. In the case of the rear-wheel driven bicycle, the identical rear-wheel driver unit used for said two-wheel driven bicycle is used, and the front wheel and the handlebars are just the same as that of a conventional bicycle.

  • Publication number: 20100270772
    Abstract: This invention concerns a recreational vehicle comprising a body having a front wheel and a rear wheel mounted thereto by a mounting system that allows relative movement between an axis of the rear wheel and an axis of the front wheel. Biasing means is provided for urging the axes of the front and rear wheels towards each other. A locking system locks at least one of the front and rear wheels against rotation in one direction whilst allowing rotation of that wheel in the other direction. The invention also concerns a recreational vehicle comprising a body having at least one bouncing element mounted thereto, the bouncing element having sufficient resilience to allow a user to bounce the recreational vehicle and wherein the bouncing element is mounted to the body by a mounting system, which defines an axis of rotation for the bouncing element.
