Abstract
Abstract An in-line wheeled skate has a frame with opposed, parallel side rails and wheel arranged in tandem between the side rails, each wheel mounted on an axle. Each axle end is surrounded and supported by a resilient element in a cushioning aperture of the side rail. Each axle end also extends into a guiding aperture of the side rail overlapping the cushioning aperture. The guiding aperture has a first dimension selected relative to a corresponding first dimension of the axle end to limit movement of the axle end relative to the side rail in the direction of a first plane, and a second dimension selected relative to a corresponding second dimension of the axle end to permit resilient movement of the axle end relative to the side rail in the direction of a second plane transverse to the first plane.
