Open the CIPO recordAbstract From the Canadian patent
This invention provides a unitary skate component extending from a blade to the sole of a skate boot. The structure has two spaced apart walls which are vertical and substantially parallel at their lower portions and which at their upper portions curve smoothly upwardly and outwardly in opposite directions through a substantial radius to terminate in flange portions which may be attached to the boot sole. The large radius provides yieldable impactabsorbing regions without stress-concentration points.
