Abstract
A roller skate having enhanced steerability and stability is disclosed. The skate includes a platform for supporting a skater's foot and front and rear wheel trucks secured to the underside of the platform. A pair of front wheels is rotatably mounted in transverse axial alignment on the front wheel truck and a pair of rear wheels is rotatably mounted in transverse axial alignment on said rear wheel truck. The pairs of front and rear wheels are also in parallel axial alignment with each other and mounted on their respective wheel trucks for resiliently controlled, tilting movement about downwardly inclined longitudinal axes. In addition, a fifth wheel is rotatably mounted on the front wheel truck between the pairs of front and rear wheels and in parallel axial alignment with the wheel pairs.
