Patent ID: 7980568

Claim:
A wheel skate device, comprising: a unit that includes a frame; at least one wheel rotatable about a wheel axis within a plane of rotation; rotary couplings arranged to guide rotation of the at least one wheel about the wheel axis; and a foot placement platform supported by the frame to define a platform surface that is elongated in a direction substantially transverse to the plane of rotation of the wheel and extends clear of the wheel axis, the foot placement platform being arranged free of any constraint that would otherwise substantially prevent the foot placement platform from rocking back and forth about the wheel axis relative to the at least one wheel; wherein the foot placement platform is movable relative to the frame between a first in-use position and a second stowage position, the platform in the in-use position extending further from the plane of rotation than in the stowage position; and wherein in the stowage position, the platform is positioned substantially parallel to the plane of rotation.
