CA 2175492

A mounting plate (20, 120) for a linear skate upon which a plurality of wheel supporting brackets (22, 24, 26 & 28) are affixed in an equally spaced, generally aligned relationship. A wheel-receiving axle (32, 34, 36 & 38) is secured in each bracket, with each axle intended to receive thereon a closely fitting skate wheel (12, 14, 16 & 18). Each axle has a novel, expansion-producing arrangement (52, 62) enabling the outer end of the axle to be enlarged so as to tightly engage the non-rotatable inner portion (80) of a respective skate wheel. Each wheel is thus retained on its respective axle in a fully operational manner, without fear of the wheel coming off the end of the axle. The mounting plate has raised shoulders (84 & 86; 126 & 128) along each long side, serving not only to prevent undesired bending or twisting, but also serving to prevent the several wheel- supporting brackets from twisting out of a desired relationship to the mounting plate.

L'invention se rapporte à une plaque de montage (20, 120) de patin à roulettes à roues en ligne, sur laquelle on monte une pluralité de pattes de fixation des roues (22, 24, 26 et 28) de façon alignée et à intervalles réguliers. Chaque patte comporte un axe de roue (32, 34, 36 et 38) sur lequel une roue de patin s'adapte étroitement (12, 14, 16 et 18). Les axes sont équipés d'un nouveau système d'extension (52, 62) qui rend extensible l'extrémité extérieure de l'axe et permet ainsi à la partie intérieure non rotative (80) de la roue de venir en contact serré avec cet axe. On peut ainsi monter les roues sur leurs axes respectifs et utiliser le patin à plein rendement sans craindre que les roues se détachent de l'extrémité de leur axe. Des épaulements (84 et 86; 126 et 128) sont prévus sur chaque long côté de la plaque de montage, à la fois pour empêcher les courbures ou les torsions indésirables et pour empêcher que les torsions ne fassent sortir les différentes pattes de fixation des roues de la position correcte par rapport à la plaque de montage.
