ABSTRACT:
The invention relates to a frame for a skate intended for coupling to a skating shoe provided with a sole plate, which frame carries at least three freely rotatable wheels lying in one principal plane or a skate blade.
The insight underlying the invention is that for the achieving of high speeds and the best possible cornering, the above outlined principles from the ice skating sport could be applied to the sport of roller skating.
In this respect the invention provides a frame for a roller skate as described above of which each connected group of at least two wheels has a tangent which extends outside each remaining wheel. In the case of three wheels for example, only two wheels touch the ground simultaneously using such a construction. This could be regarded as a discrete approach to the curvature of an ice skate gliding surface.
