Abstract A roller/ice skate base includes an upper structure for attaching a skate boot thereon and having two side walls integral therewith for receiving a plurality of wheels or a lower structure with a fixed ice blade therebetween. The upper structure includes a plurality of spaced square recesses formed on an outer surface of each side wall. Each recess has a corresponding boss protruding from an inner surface of each side wall. Each boss has a round hole extending from the inner surface of the side wall to an inner surface of each corresponding recess. The lower structure includes a number of holes corresponding to the square recess. Each hole has a U-shaped recess formed on each side thereof, each U-shaped recess receiving a boss therein when the lower structure is received by the upper structure.
In a combination of a roller/ice skate base and an ice blade structure, said roller/ice blade base comprising an upper structure for attaching a skate boot thereto and said ice blade structure comprising a lower structure for fixing an ice blade thereto; said upper structure comprising a pair of parallelly-spaced side walls, each said side wall comprising a plurality of spaced first through holes, each said first through hole having a square recess formed therearound on an outer surface of said side wall; each said side wall further comprising a plurality of bosses, each boss being formed on an inside surface thereof around each said first through hole; said lower structure comprising a plurality of spaced second through holes corresponding to said first through holes of said side walls and a plurality of U-shaped recesses being formed around said second through holes on outer sides of said lower structure; said lower structure being receivable between said side walls with said U-shaped recesses receiving said bosses, thereby aligning said through holes of said upper and lower structures to receive a bolt therethrough with said square recesses receiving compatible square portions of the bolts.
