20110245042 | Load Wheel for a Self-Propelled Exercise Device - A rotational bearing has an outer surface and an outer layer attached to the outer surface of the bearing by overmolding, bonding or mechanical fasteners. The outer layer has an outer surface which rotatably engages a bearing surface of a track along which the bearing device is adapted to travel, and is of a material softer than the material of the track bearing surface, such as a polymer or a relatively soft metal. In one example, the bearing is rotatably attached to a foot link carrying a foot engaging platform of a human powered conveyance or exercise system. | 10-06-2011 |

20100298101 | Adjustable Crank Arms for Elliptical Bike and Method of Use - An apparatus including a frame with a pivot axis defined thereupon; a drive wheel coupled to the frame; a first and a second foot link operably coupled to drive wheel to transfer power to the drive wheel so as to propel the apparatus, each including a foot receiving portion for receiving an operator's foot, a front end, and a rear end; and an adjustable stride length mechanism coupling the rear end of the foot link to the pivot axis at a radial length, the adjustable stride length mechanism including a plurality of attachment points for adjusting the radial length. | 11-25-2010 |
20100295263 | Interlocking Guide Tracks for Elliptical Bike and Method of Use - An apparatus includes a frame with a pivot axis defined thereupon; a drive wheel coupled to the frame; a first and a second foot link operably coupled to drive wheel to transfer power to said drive wheel so as to propel the apparatus, each including a foot receiving portion for receiving an operator's foot, a front end, and a rear end; and a pair of internal guide track systems coupled to the frame, each internal guide track system being operative to engage the front end of each foot link internal to the internal guide track system and to direct said front end along a reciprocating path of travel while providing retention to each foot link. | 11-25-2010 |
20100295262 | Folding Steering Column for Elliptical Bike and Method of Use - A foldable steering column of vehicle including a steering member with a steering fork. The foldable steering column includes a base coupleable to the steering fork; a steering tube pivotally coupled to the base between at least a first position aligned with the base and second position not aligned with the base; and a sleeve operably associated with the base and the steering tube for positioning between a first position where the steering tube is secured to and aligned with the base and a second position where the steering tube is free to pivot relative to the base. | 11-25-2010 |
20100244399 | Self-Propelled Vehicle Propelled by an Elliptical Drive Train Including Foot Retention - An apparatus including a frame; a drive wheel coupled to the frame; a first and second foot link operably coupled to drive wheel to transfer power to said drive wheel so as to propel the apparatus, each including a foot receiving portion for receiving an operator's foot and a retention mechanism for retaining the operator's foot on the foot receiving portion of the foot link. | 09-30-2010 |
20100244398 | Self-Propelled Vehicle Propelled by an Elliptical Drive Train With Crank Bearing - An apparatus including a frame with a pivot axis defined thereupon, a crank arm bearing at the pivot axis; a first and a second crank arm coupled to the crank arm bearing; a front wheel and a rear wheel coupled to the frame, the rear wheel including a rear wheel axle; a first and a second foot link, operably coupled to drive wheel to transfer power to said drive wheel so as to propel the apparatus, each foot link including a foot receiving portion for receiving a user's foot, a first end coupled to the frame, and a second end coupled to a respective one of the first and the second crank arms, wherein the crank arm bearing is located rearward of and above the rear wheel axle. | 09-30-2010 |
20100219604 | Self-Propelled Vehicle Propelled by an Elliptical Drive Train With Adjustable Foot Locations - An apparatus including a frame; a drive wheel coupled to the frame; a first and second foot link operably coupled to drive wheel to transfer power to the drive wheel so as to propel the apparatus, each including a foot receiving portion for receiving an operator's foot, where each foot receiving portion allows for at least two repeatable foot positions for the operator's foot. | 09-02-2010 |
20100219603 | Self-Propelled Vehicle Propelled by an Elliptical Drive Train With Direct Drive Power Transfer System - An apparatus including a frame; a drive wheel coupled to the frame; a first and second foot link, each including a foot receiving portion for receiving a user's foot; and a direct drive power transfer system coupled to the first and second foot links and the drive wheel such that when the foot links are operated by a user, the direct drive power transfer system applies propulsive force to the drive wheel without the use of a chain or belt. | 09-02-2010 |
20100219602 | Self-Propelled Vehicle Propelled by an Elliptical Drive Train With Adjustable Stride Length Mechanism - An apparatus including a frame; a drive wheel coupled to the frame; a first and a second foot link operably coupled to drive wheel to transfer power to said drive wheel so as to propel the apparatus, each including a foot receiving portion for receiving an operator's foot, a front end, and a rear end; and an adjustable stride length mechanism operable to change a stride length of an operator's foot positioned on the foot receiving portion of the foot link. | 09-02-2010 |
