<p>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.</p> |
