ABSTRACT:
An in-line skate enables the wheels to follow an arc when turning, thereby offering such enhanced performance characteristics as energy return, shock absorption and reduced turning diameters. The skate comprises a flexible beam affixed to a rigid boot backbone by a single attachment position bracket. The flexible beam carries the skate wheels thereon, and is adapted to flex about its single attachment location in response to the radial force generated while turning, aligning the wheels of the skate toward the radius of the turn, making the turn easier and more energy efficient. Additionally, flexing of the beam under the load of the skater in usage will result in a spring back of the beam when the load is reduced, providing an energy return system to recover energy that would otherwise be lost during certain skating maneuvers.
