  • Patent number: 8449042
    Abstract: The present invention provides an adhesive wheel balance weight capable of drastically reducing costs from those of conventional ones, and a process for producing the same. In an adhesive wheel balance weight (W) comprising a weight body (P) and an adhesive tape (T) for attaching the weight body (P) to a vehicle wheel, the weight body (P) comprises a folded weight comprising a folded metal plate piece. The folded weight of the present invention can be formed from a relatively inexpensive raw material sheet at a high yield rate. It is preferable that the raw material sheet is a zinc-coated steel sheet, because no rust-proofing aftertreatment is necessary and therefore further cost reduction is achieved, and its environmental burden is small.

  • Publication number: 20110012419
    Abstract: To provide a wheel balance weight in which a release coated paper is likely to be detached when assembling it with a wheel. A wheel balance weight according to the present invention is such that, in a wheel balance weight including: a substantially-strip-shaped weight; an adhesive-tape portion whose tape front surface is fixed to a weight rear surface; and a release coated paper covering a tape rear surface, it makes the release coated paper likely to be pinched by adjusting the widths of the adhesive-tape portion and release coated paper. Since the wheel balance weight according to the present invention is such that the release coated paper is less likely to be detached before the assembly operation and the release coated paper is likely to be pinched upon assemblage, the handling becomes easy and additionally the workability when assembling the wheel balance weight with a wheel has improved.

  • Publication number: 20080258537
    Abstract: A wheel balance weight includes a weight, an adhesive seal, a release coated paper, and a protrusion. The protrusion is made of at least a part of the release coated paper, is disposed along a longitudinal direction of the weight, protrudes parallelly to a widthwise direction of the weight beyond one of opposite widthwise ends of the adhesive seal, is located at least around a position, which corresponds to the weight's center of gravity, and is provided with a cut-off, which is placed at the position corresponding to the weight's center of gravity. The wheel balance weight demonstrates improved workability upon assemblage.

  • Patent number: 7267410
    Abstract: A balance weight is formed into a columnar shape to extend in an axial direction of a spoke connecting a wheel hub and a rim of a spoke wheel, has an insertion recess extending over its entire axial length to open in its outer periphery, and is secured by crimping to the spoke to surround the spoke inserted into the insertion recess. A reduced section having a decreased outer diameter is provided on the balance weight at an end facing toward the wheel hub. Thus, the balance weights can be mounted to the adjacent spokes of the spoke wheel without interference therebetween.

  • Patent number: 6874856
    Abstract: A wheel balance weight includes a weight and an installation member. The weight is composed of at least one member selected from the group consisting of zinc and a zinc-based alloy, is formed as a substantially strip shape having a substantially uniform thickness, and has opposite surfaces and at least a groove. The groove is formed in at least one of the opposite surfaces of the weight, and crosses in the width-wise direction of the weight. The installation member is adapted for installing the weight to a rim in a wheel. Since the weight is composed of zinc or a zinc-based alloy, environments are inhibited from being polluted when the wheel balance weight is abolished. Moreover, it is possible to manufacture the wheel balance weight at reduced costs and install it to wheels with ease.

  • Patent number: 6659567
    Abstract: A wheel balance weight includes a weight and a double-sided tape. The weight is formed as a substantially strip shape, is made from a ferrous alloy, and has opposite top and bottom surfaces and at least a groove. The groove is formed in the bottom surface of the weight, and crosses in the width-wise direction thereof being substantially perpendicular to the longitudinal direction thereof. The double-sided tape has opposite adhesive surfaces being disposed back to back with each other. One of the opposite adhesive surfaces is to be bonded onto the bottom surface of the weight, and the other one of the opposite adhesive surfaces to be bonded onto an inner peripheral surface of a wheel. Accordingly, it is possible to curve the weight with less force. Hence, it is possible to install the wheel balance weight to a wheel with ease.

  • Patent number: 6592188
    Abstract: A wheel balance weight includes a plurality of weights, an adhesive sealing member and a regulatory member. The adhesive sealing member fastens the plurality of weights onto an inner peripheral surface of a rim in a wheel, and has an adhesive surface to be bonded to the inner peripheral surface. The regulatory member inhibits at least two of the plurality of weights, being disposed to neighbor with each other, from moving by greater than a predetermined magnitude. Hence, the wheel balance weight deal can be dealt with readily before it is installed to the wheel, is likely to conform to the inner surface, and can have a desired mass by adjusting the number of the weights.
