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.

Cette invention concerne un patin à roulettes offrant une facilité de direction et une stabilité accrues. Ce patin comporte une plate-forme portant le pied du patineur et des essieux avant et arrière fixés sur le dessous de la plate-forme. Une paire de roues avant est montée rotatif selon un alignement axial transversal sur l'essieu avant, et une paire de roues arrière est montée selon un alignement axial transversal sur l'essieu arrière. Par ailleurs, les paires de roues avant et arrière sont montées selon un alignement axial parallèle l'une par rapport à l'autre sur leurs essieux respectifs, ce qui leur permet de pivoter en souplesse sur leur axe longitudinal incliné vers l'avant. De plus, une cinquième roue est montée rotatif sur l'essieu avant entre les paires de roues avant et arrière selon un alignement axial parallèle par rapport à ces dernières.
