An in-line roller skate for use by children has a stability enhancing mechanism and a movement limiting mechanism. The stability enhancing mechanism includes two rollers, mounted on an axle, that are selectively positionable side-by-side in a normal mode or spaced apart in a stable mode. A combine arm having two fingers pivots downward to cam the rollers inward from the stable to the normal mode. Alternately, a separator arm pivots downward to slide the two rollers apart on the axle from the normal mode to the stable mode. The movement limiting mechanism includes a roller, mounted on an axle, that has teeth formed on the radially inner surface of the cylindrical outer portion. A pawl has a pawl arm extending into the inner cylindrical portion of the roller to engage the teeth and a pawl tongue that extends into a pawl adjuster. The pawl adjuster has a retaining slot and is slidably positioned in a well in the front chassis of the skate to cam the pawl up into a nonengaging position, corresponding to the free wheeling mode. The pawl adjuster can also be positioned to allow the pawl to ride on the teeth of the roller, corresponding to the forward only mode, or to restrain the pawl in the engaging position, corresponding to the full stop mode.

A roller skate comprising: a body; a roller mounted to said body for rotation in a forward direction and an opposite, reverse direction, and having an outer, rolling surface and an inner surface disposed substantially concentric with, and radially inwardly from, said outer surface; a ratchet tooth coupled to said roller on said inner surface and projecting radially inwardly with respect to said inner surface to a ratchet tooth inner radius; a pawl having a guide portion, a pawl arm, and an engaging end; means for guiding said pawl along a defined pawl path between a first position in which said engaging end is spaced radially inwardly from said ratchet tooth inner radius and a second pawl position in which said engaging end is disposed radially outwardly from said ratchet tooth inner radius, said pawl guide means being disposed at least partially within said inner surface and engaging said guide portion; and a pawl adjuster disposed at least partially outside said outer surface, being movable between first, and second retainer positions, and being coupled to said pawl arm to move said pawl along said pawl path, said first and second retainer positions corresponding to said first and second pawl positions, respectively, said pawl adjuster in said second position allowing movement of said pawl along said pawl path away from said second pawl position in a ratcheting motion to permit said roller to rotate in only one of said forward and reverse directions. An in-line roller skate having a roller assembly, comprising: a body; an axle coupled to said body; first and second rollers rotatably mounted on said axle; said first roller being slidably mounted on said axle for lateral movement between a first position adjacent said second roller and a second position spaced from said second roller; a separator arm coupled to said body and selectively moveable between said first and second roller for sliding said first roller along said axle from said first position to said second position; and a combine arm coupled to said body for sliding said first roller along said axle from said second position to said first position.
