ABSTRACT:
A roller skate has a truck supporting its rear-wheel axle on which a rearwardly extending rocker is swingable about a horizontal axis, the rear end of this rocker carrying a control roller while its front end engages or forms a pair of pressure elements disposed between the rear wheels. Normally, with all four wheels touching the ground, the control roller is elevated above the road surface; when, however, the front of the skate is lifted in a pivotal motion about the rear axle, this roller contacts the ground and causes the rocker to swing against a spring force whereby the pressure elements are cammed outward to engage the inner faces of the rear wheels for exerting a braking force thereon. The wheel faces may be clad with thin metal disks which coact with the pressure elements and which also form seats for wheel-supporting ball bearings.
