In-line wheeled skate
First Claim
1. An in-line wheeled skate, comprising:
- a frame having a first side rail and a second side rail opposed and generally parallel to said first side rail,a plurality of wheels arranged in tandem between said first side rail and said second side rail,a plurality of axles, each said axle having a first axle end surrounded and supported by a first resilient element disposed in a first cushioning aperture defined by said first side rail, and each said axle having an opposite, second axle end surrounded and supported by a second resilient element disposed in a second cushioning aperture defined by said second side rail,each one of said plurality of wheels supported upon a corresponding one of said plurality of axles for rotation about a central axis of said wheel,said first side wall defining a first guiding aperture overlapping said first cushioning aperture, said first axle end extending into said first guiding aperture, said first guiding aperture having a first aperture dimension in a first plane of said central axis and a second aperture dimension in a second plane of said central axis transverse to said first plane, said first axle end having a first axle dimension in said first plane and a second axle dimension in said second plane, and said first axle dimension selected relative to said first aperture dimension to restrict movement of said first axle end in a direction of said first plane, and said second axle dimension being selected relative to said second aperture dimension to permit resilient movement of said first axle end in a direction of said second plane,said second side wall defining a second guiding aperture overlapping said second cushioning aperture, said second axle end extending into said second guiding aperture, said second guiding aperture having a first aperture dimension in a first plane of said central axis and a second aperture dimension in a second plane of said central axis transverse to said first plane, said second axle end having a first axle dimension in said first plane and a second axle dimension in said second plane, and said first axle dimension selected relative to said first aperture dimension to restrict movement of said second axle end in said first plane, and said second axle dimension being selected relative to said second aperture dimension to permit resilient movement of said second axle end in said second plane.

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.
