Abstract

426,457. Roller skates. CLEDINA, R., 283, Rue St. Gilles, Liege, Belgium. June 18, 1934, No. 18060. Convention date, June 17, 1933. [Class 132 (i)] [See also Group XXXI] A roller skate of the type steered by lateral inclination of the foot is characterized by a metal frame enveloping a foot platform and supporting the rear axle, and extended in the front by a forked bar terminated by a member controlling the steering of the front wheel and arranged so that the platform is under the horizontal axial plane of the wheels. As shown, the skate comprises a metal frame 1 having two lateral branches 1<a>, 1<b> in which is mounted the axle 2 of the rear rubber-tyred wheel 3 which has a ratchet-and-pawl device to prevent backward motion. Stays 4 provide a support for a metal footplate 5 pivoted on a shaft 6, and the axle 2 carries one or more drums 7 on each of which is pressed a brake band 8 secured at the free end to the footplate 5. The frame 1 is pivoted on a bar 10 forming a bearing 11 in which can turn vertically a shaft 12 traversed by the axle 13 of the front wheels and rigid with a toothed sector 14 with which engages a toothed sector 15 carried at the end of a bar-shaped extension 16 of the frame 1. Swinging of the frame 1 about the pivot 10 turns the axle 13 and steers the skate. Springs 17 are connected between the bearing 11 and the bar 16. In modifications, flexible cables actuated by the movement of the footplate 5 co-operate with brake-drums on either or both of the front and rear wheels. The toothed sectors may be replaced by a fork adapted to engage the front wheel axle, or the front wheel axle may be turned by a friction disc drive provided with pins engaging the axle. The Specification as open to inspection under Sect. 91 comprises also the application of the mechanism to scooters. This subject-matter does not appear in the Specification as accepted.
