Roller skate with brake

A roller skate construction having at least one wheel attachable to a foot receiving boot having a toe and heel defining forward and rearward skating directions comprising:

• support means for attachment to said boot;
• a shaft secured to the support means having an axis extending in said skating directions;
• a substantially spherical wheel defining a peripheral surface;
• and
• bearing and axle means secured to the shaft and wheel and contained substantially within the wheel peripheral surface for rotatably securing said wheel relative to the shaft for rotation in two orthogonal directions perpendicular to each other.

A roller skate construction having at least one wheel attachable to a foot receiving boot having a toe and heel defining forward and rearward skating directions, said at least one wheel for normally rotating in said skating directions, said construction comprising:

• support means including at least one depending support member for attachment to said boot;
• a shaft extending in said skating directions secured to said support member;
• a plurality of like wheels each comprising two segments arranged to independently rotate in planes parallel to said skating directions and each having at least one surface substantially defining a surface of revolution in at least two orthogonal directions;
• a plurality of bearings secured to the shaft, each bearing corresponding to a different wheel;
• axle means including a ring member secured to each bearing for rotation about said shaft and a pair of wing axles secured to each ring member and having coaxial axes extending transversely to said skating directions;
• bearing means secured to each wing axle for rotatably receiving a different wheel segment of said two segments and forming said two wheel segments into a single wheel;
• and
• brake means including a cam and resilient detent means secured to each wing axle to contact a surface of said cam, said cam and detent means being arranged to provide progressively increasing resistance to the rotation of said wing axles and associated ring member about said shaft from a neutral position.
