Abstract

Tandem wheeled roller skates having braking means operable against the hubs of a pair of the wheels in tandem. When at least two pairs of wheels are mounted in line in tandem a separate brake is mounted on a front pair and another brake is mounted on the rear pair in order that braking pressure can be varied or applied uniformly in unison. The brake can be applied by the wearer of the skate by merely stooping and adjusting the head of a tightening nut.

Claims

1. A tandem-wheeled roller skate having a plurality of wheels arranged in single file substantially centrally of and along the length of a foot support platform comprising in combination:

A pair of longitudinally extending spaced apart frame plates projecting downwardly substantially at right angles from said platform and attached thereto to form a rigid structure therewith;

A hub assembly for each wheel;

A tire surrounding each hub assembly;

An axle means for each wheel projecting through said hub assembly and through aperture provided through said pair of frame plates;

Means to secure each axle between said frame plates with each wheel and hub assembly thereof free running therebetween;

At least one pressure brake plate extending between a pair of said wheels and having at least two annuli formed therein whereby one annuli is fittable over an axle of one wheel and the other is fittable over the axle of said other pair of wheels to allow said wheel to rotate freely with said brake plate positioned between said frame plate and said hub assembly of said wheel;

A disc surface provided outwardly of each wheel surrounding each hub assembly co-planar with the annuli of said brake plate;

Means provided substantially midway of said brake plate between said pair of wheels adapted to bear against said plate to bend it inwardly against said disc surface of said wheel hub assembly thereby to induce braking pressure to said wheels.
