Claim 1
Independent Claim
193 words
A runnerless roller sled which comprises: a bed having a center line; a longitudinal, laterally flexible support member discontinuously attached to said bed beneath said center line by a plurality of spaced pins, the forwardmost pin being a pivot pin, said support member having a front and rear section; a front pair of roller wheels attached transversely to and beneath said front section; a rear pair of roller wheels attached transversely to and beneath said rear section; a steering bar attached transversely to said front section forward of said pivot pin and having handle grips at each end; a pair of brake levers mounted on said steering bar, one forward of each handle grip; a pair of brake rods, one each connected to one of said brake levers and slidably mounted along a lateral face of said support member; a pair of spring-loaded brake rocker arms, one each pivotally mounted on a lateral face of said rear section of said support member and connected to one of said brake rods; and a pair of brake shoes, one operatively connected to each brake rocker arm and engageable with one of said rear roller wheels.
