Improved blow-molded wheels, methods for producing the same, and children's ride-on vehicles including the same are disclosed. The blow-molded wheels may include a blow-molded wheel body that is configured to rotate about an axis and has a tread surface that extends circumferentially around the wheel body and may have a circumferential profile that is defined as the locus of points at which the radial distance from the axis to the tread surface is greatest at each position around the circumference of the tread surface. The radial distance from the axis to the circumferential profile may change from a first radius to a second radius that is larger than the first radius at a plurality of spaced-apart positions along the circumferential profile. The method for producing the blow-molded wheels may include providing a mold with pinch-off rings that have an opening configured to form the circumferential profile.
L'invention concerne des roues soufflées améliorées, leurs procédés de fabrication, et des véhicules autoportés pour enfants les comprenant. Les roues soufflées peuvent englober un corps de roue soufflée qui est configuré pour tourner autour d'un axe, possède une surface de roulement s'étendant de manière circonférentielle autour du corps de roue et peut avoir un profil circonférentiel défini comme le lieu des points auquel la distance radiale entre l'axe et la surface de bande de roulement est plus importante à chaque position autour de la circonférence de la surface de roulement. La distance radiale entre l'axe et le profil circonférentiel peut passer d'un premier rayon à un second rayon plus important que le premier rayon en une pluralité de positions espacées le long du profil circonférentiel. Le procédé de fabrication des roues soufflées peut consister à utiliser un moule avec des anneaux de pincement présentant une ouverture configurée pour constituer le profil circonférentiel.
