Abstract
Skates having increased lateral stability for use in speed skating and hockey. A primary blade is provided with first and second secondary blades which extend laterally outwardly from the primary blade at angles therefrom. In a first preferred embodiment, these secondary blades extend outwardly at equal 45° angles and engage the surface of the ice when the primary blade tilts either direction through an angle of 45°. In a second preferred embodiment, the inner secondary blade extends outwardly at a lesser angle of say 30° so that double blade engagement of the ice can be more easily accomplished for sprinting situations.
Claims14
Ice skates comprising
- a) a pair of skate blade assemblies, each assembly including
- i) a blade support to which a primary blade and a pair of secondary blades are attached;
- ii) a primary blade having a first mean blade thickness and a first height,
- iii) first and second secondary blades which each have a second mean blade thickness substantially equal to said first mean blade thickness, said first and second secondary blades each being attached directly to and extending angularly outwardly from opposing lateral faces of said primary blade at first and second predetermined angles;
- b) means to attach a pair of said blade assemblies to right and left feet of a wearer, respectively;
- whereby when at least one of said primary blades of said pair of primary blades is in contact with and extends at a third predetermined angle with an ice surface, said first secondary blade will come in contact with the ice surface and when at least one of said primary blades is in contact with and extends at a fourth predetermined angle with the ice surface, said second secondary blade will come in contact with the ice surface, said first and second secondary blades providing auxiliary support significantly reducing a risk of a fall resulting from said primary blade slipping laterally on the ice surface.
