Claim:
An in-line roller skate comprising: a shoe; and a wheel supporting frame extending from said shoe for supporting aligned wheels and comprising: a main frame body mounted to said shoe, said main frame comprising first and second pairs of wheel-receiving arms for rotatably receiving respective wheels and shafts; a first auxiliary frame body comprising a first pair of arms for rotatably receiving a leading wheel and a shaft and a second pair of arms for being pivotally mounted to the shaft of the wheel received by one of said first and second main frame wheel-receiving arms and adjacent to the wheel received by said auxiliary frame; a first resilient and deformable member interposed between said first auxiliary frame body and said shoe and between the two adjacent wheels for extension and compression along the vertical distance between said auxiliary frame body and said shoe; a second auxiliary frame body pivotally mounted to said main frame body and carrying a trailing wheel; a second resilient and deformable member being interposed between said second auxiliary frame body and said shoe, wherein said first auxiliary frame body is so pivotable as to provide for moving said leading wheel towards and away from said shoe for a distance determined by the extension and compression of said first resilient and deformable member, said second auxiliary frame body being so pivotable as to provide for moving said trailing wheel towards and away from said shoe for a distance determined by the extension and compression of said second resilient and deformable member.
