Roller skate or the like with brake attachment

In a wheeled skating device having at least one front wheel and a pair of rear wheels journaled on a transverse axle,

• the combination therewith of:
• a truck member between said rear wheels supporting said axle and forming a housing disposed below said axle;
• a rocker member fulcrumed on said truck member for limited swinging about a pivotal axis perpendicular to said rear wheels;
• a roller journaled on a tail end of said rocker member rearwardly of said axle;
• resilient means tending to maintain said rocker member in a limiting position relative to said truck member in which said roller is elevated above a road surface contacted by all said wheels;
• a pair of pressure elements slidably disposed in said housing close to said rear wheels for displacement substantially parallel to said axle;
• and
• a spring-loaded spreader carried by said rocker member and interposed between said pressure elements for driving same into frictional engagement with said rear wheels upon an elevation of said front wheel sufficient to lower said roller onto the road surface and to swing said rocker member about said pivotal axis against the force of said resilient means whereby a braking force is exerted on said rear wheels, said spreader being swingable jointly with said rocker member about said pivotal axis.

• the combination therewith of:
• a truck member between said rear wheels supporting said axle;
• a rocker member fulcrumed on said truck member for limited swinging about a pivotal axis extending rearwardly of said axle in a direction perpendicular to said rear wheels;
• a roller journaled on a tail end of said rocker member rearwardly of said axle, said truck member forming a housing extending rearwardly from said axle above said rocker member;
• resilient means tending to maintain said rocker member in a limiting position relative to said truck member in which said roller is elevated above a road surface contacted by all said wheels;
• a pair of pressure elements slidably disposed in said housing close to said rear wheels on one of said members for displacement substantially parallel to said axle;
• and
• a spring-loaded spreader interposed between said pressure elements for driving same into frictional engagement with said rear wheels upon an elevation of said front wheel sufficient to lower said roller onto the road surface and to swing said rocker member about said pivotal axis against the force of said resilient means whereby a braking force is exerted on said rear wheels, said spreader being vertically guided in said housing and resting on said rocker member.
