CA 2166573

The proposed single-track roller skate is provided with a frame (3) attached to the shoe (2), or with several frame sections which can be attached to the shoe (2). At least three wheels (4, 5, 6, 7) are mounted one behind the other along the line of movement in the frame (3) or frame sections. Each wheel has a rolling surface (18, 19) around its circumference, this rolling surface being substantially symmetrical about the longitudinal mid-plane of the wheels (4, 5, 6, 7) and curved in axial section; the rolling surfaces (18) of at least one front wheel (4) and of at least one rear wheel (7) at a distance from the longitudinal mid-plane (.epsilon.) are at a relatively greater normal distance from a plane () parallel to the axis and tangential to the rolling surface (18) than the rolling surface (19) of at least one middle wheel (5, 6): the arrangement ensures that, when the roller skate (1) tips in relation to the tangential plane (), the front and/or rear wheel (4, 7) are lifted or the contact pressure exerted by these wheels (4, 7) is reduced.

Patin à roulettes du type à une seule voie, présentant un châssis (3) relié à une chaussure (2), ou plusieurs parties de châssis susceptibles d'être fixées à cette chaussure (2), dans lequel il est prévu, sur le châssis (3) ou sur les parties de châssis, au moins trois roulettes (4, 5, 6, 7) disposées l'une derrière l'autre dans le sens du déplacement, chacune de ces roulettes présentant le long de sa périphérie, une surface de roulement (18, 19) sensiblement symétrique par rapport au plan médian longitudinal des roulettes (4, 5, 6, 7) et incurvée dans une section axiale. Les surfaces de roulement (18) d'au moins une roulette avant (4) et d'au moins une roulette arrière (7) présentent, par rapport à un plan tangentiel (?) parallèle à l'axe, sur la surface de roulement (18), à distance du plan médian longitudinal (.epsilon.), une distance normale relativement plus grande que la surface de roulement (19) d'au moins une roulette médiane (5, 6), de telle façon que lorsque le patin (1) bascule latéralement par rapport au plan tangentiel (?), la roulette avant et/ou arrière (4, 7) soient soulevées, ou bien la pression d'appui exercée par ces roulettes (4, 7) soit réduite.
