ABSTRACT:
A skate having simultaneously retracted front and rear wheels. A retraction mechanism mounted below the show includes a linkage member yoked to all wheels. The retraction member includes cams or ramps which guide the wheels to move in an inclined direction, thereby retracting into the housing of the retraction mechanism and extending below the housing. When retracted, only the flat bottom surface of the housing is exposed below the housing. A linkage member rotated by a key disposed at the heel of the shoe moves the wheels along the ramps in tandem.
