Abstract: The present invention provides track assemblies and a method that allow bringing the contact patch towards the inside (the outside) of the suspension arm, by providing a asymmetric track assembly, either by lowering at least one inside (outside) support wheel relative to the remaining support wheels, or by using a belt that comprises, transversally, at least one first profile on the outer (inner) side thereof lower than a second profile on an inner side thereof.

Abstract: A vehicle wheel assembly is provided which includes a vehicle frame having a first axle, a wheel assembly having a housing with an aperture engaging the first axle and enabling the wheel assembly to pivot in a first plane about a first axis formed by the first axle. A cylindrical member is carried by the housing of the wheel assembly, the cylindrical member and housing are arranged perpendicular to the first axle. A first wheel is pivotably connected to a first portion of the cylindrical member and a second wheel is pivotably connected to a second portion of the cylindrical member. The first wheel and second wheel independently pivot in a second plane about a second axis formed by the cylindrical member. The first axis is arranged perpendicular to the second axis and the first plane is arranged perpendicular to the second plane.

Abstract: A vehicle with a frame connecting a driver wheel, an idler wheel and mid-roller wheels, an endless track belt being tensioned around the driver wheel and the idler wheel and being in contact with the mid-roller wheels on a lower run thereof, the mid-roller wheels being arranged in bogies, including a front bogie having a first pivot axis, a middle bogie and a rear bogie arranged in tandem having a second pivot axis, wherein the first pivot axis and said second pivot axis act as load transfer pivots.

Abstract: A track formed of a molded rubber base sandwiching a cord layer and a single layer of ply fabric extending longitudinally of the track.

Abstract: A multipurpose personal training device with a pair of press arms that can be set to numerous different lateral angles. Each press arm can be equipped with a functional trainer handle coupled by cable and pulleys to an adjustable weight engine. The final pulley at the end of each arm is free to rotate to any angle. In addition to exercises involving the arms, the device can supply a full complement of most standard training exercises.

Abstract: An abdominal muscle exercise machine that generally contains a diagonal member with an adjustable seat and a backrest and a pivot member that pivots with respect to the diagonal member. A chest push can be mechanically coupled to the pivot member through an adjustable force multiplier. An optional counterweight can be placed near one end of the pivot member to lighten the force, or an optional load weight can be placed near the other end of the pivot member to increase the force. The pivot member can be constructed to telescope or otherwise adjust for different body sizes. The machine provides a smooth exercise where the top and bottom portions of the body move together in a linked fashion. The machine of the present invention works without heavy external weights.
