Abstract: An adjustable skate truck assembly is described that is mountable to an elongated skate boot. The assembly includes an upper attachment member with heel and toe pieces for mounting to the sole of the skate boot. A skate truck member is mounted to the upper member, for adjustment to vary the relationship of the upper member and boot to a surface support member on the truck. A drive operatively interconnects the upper attachment member and the skate truck member to move the skate truck member and surface support member laterally, elevationally, or both, relative to the upper attachment member. This enables the skater to adjust lateral positioning of the surface support member relative to the upper attachment member. The drive includes a first drive portion that is situated to laterally adjust a toe portion of the truck member relative to the upper attachment member and boot. A second drive operatively interconnects heel piece and truck to enable lateral adjustment of the heel piece relative to the truck.

Abstract: An in-line roller skate wheel and truck are described in which an elongated truck frame with a pair of spaced longitudinal side rails mount a plurality of roller wheels. At least one of the roller wheels has a hub core with a coaxial tire receiving shoulder. A tapered tire deflection controlling rim extends circumferentially about the shoulder, with rim side walls extending radially outward from a wide base at the tire receiving shoulder to a narrow peripheral surface. An annular resilient tire is mounted to the hub, engaging the tire receiving shoulder and encasing the tapered tire deflection controlling rim. The tire includes an annular ground engaging surface section and an annular high friction shoulder situated radially inward and axially outward of the ground engaging outer surface. The rim and tire configuration aid in maximizing speed and control in turns.
