Abstract: Several embodiments of open and closed loop frames substantially elliptical in shape are disclosed for in-line skates. Some embodiments include independent suspension for each wheel. The frame is flexible to provide shock absorption and rebound. The frame stiffness increases with the applied load. The frame stiffness and flexibility may be adjustable. The rocker of the skate is made to vary with the applied load so that the skate has high maneuverability yet is very stable when gliding. The frame includes a boot mounting system which adds no stress concentrations, thus assuring even flex properties over the entire frame, and high durability. Overload protection is included to further enhance durability.

Abstract: A drum brake design is applied to an in-line skate wheel having a circular braking surface located on an inner race. A brake shoe is pivotally mounted to a frame member. An activating end of the brake shoe is linked to the rotatable upper boot quarter. The skater activates the brake by rotating the upper boot quarter rearward. Alternate embodiments include multi-wheel brakes and a remote transmitter which activates a frame mounted electric actuator.
