Claims9
A skate board for use on ice surfaces, comprising
- an elongated platform,
- a first pair of runner blades having substantially identical ice engaging edges,
- first means pivotally mounting said first pair of runner blades to said platform near one end thereof with said blades lying in mutually parallel relationship with the longitudinal axis of said platform,
- a second pair of runner blades having substantially identical ice engaging edges,
- second means pivotally mounting said second pair of runner blades to said platform near the other end thereof with said blades lying in mutually parallel relationship with the longitudinal axis of said platform, the configuration of said ice engaging edges of said first pair of runner blades providing a greater resistance to lateral movement on an ice surface than that provided by the configuration of said ice engaging edges of said second pair of runner blades.
