Overmolded wheel-balancing weight with wheel-securing clip

摘要

A polymer overmolded wheel-balancing weight adapted to be removably secured to a wheel to correct an unbalanced wheel to prevent undesired vibrations when the wheel is rotating, the polymer overmolded wheel-balancing weight with a wheel-securing clip sized and designed to be secured to a wheel, and a weight assembled to the wheel-securing clip and at least partially covered with overmolding polymer material that is sized and designed to abuts the wheel-securing clip on a wheel side at a first location thereof, and abuts the wheel-securing clip on a side opposed to the wheel side at a second location thereof, the first location being distinct from the second location. A kit of wheel-balancing weight and a wheel with an overmolded wheel-balancing weight are also encompassed by the present application.

主权项

1. An overmolded wheel-balancing weight comprising:
a wheel-securing clip adapted to be secured to a wheel, the wheel-securing clip comprising
a wheel-securing portion at a first end thereof;a weight securing portion at a second end thereof, the wheel-securing portion comprising a cavity on a first side thereof adapted to receive therein a portion of the wheel to secure the wheel-balancing weight to the wheel, and a second side thereof, opposed to the cavity on the first side;a projecting portion, distally extending on the first side, in an offset manner with respect to the weight-securing portion, located between the wheel-securing portion and the weight-securing portion,a weight secured to the weight securing portion on the second side of the wheel-securing clip; andovermolding polymer covering the weight-securing portion and extending on the first side thereof in a radial direction toward the cavity to the projecting portion, the overmolding polymer abutting the projecting portion with a shape generally following a shape of the projecting portion that is uncovered by the overmolding material, wherein the cavity of the wheel-securing portion is sized and designed to engage and secure a portion of the wheel on a basis of an elastic deformation of the wheel-securing portion, the elastic deformation of the wheel-securing portion providing a pinching force against the portion of the wheel to mechanically secure the overmolded wheel-balancing weight to the wheel, wherein the overmolding polymer tangentially abutting the projecting portion is adapted to be compressed by the elastic deformation of the wheel-securing portion when engaging the portion of the wheel to prevent creating or increasing a gap between the overmolding material and the wheel-securing clip to avoid introducing foreign material between the overmolding material and the wheel-securing clip.
