Balance Weight for Vehicle Wheel

Abstract

An improved adhesive-type weight system for use with vehicle wheels includes one weight or a series of weights arranged as a tape. Each weight is formed of a flexible thin iron plate material having a perimeter with opposing lateral ends and opposing lateral sides. The series of weights can be oriented end-to-end or side-to-side, and each weight includes two planar sections separated by a center raised section. The center section can be a peak, an arch, a step, or some other raised configuration. Additionally, it can be tapered from one side to another. On the underside of each weight is adhesive and a release paper, which can be continuous across a series of weights or separated and applied under each individual weight. Where weights are attached to adjacent weights in series, preferably a notch or cut extends along the connection to encourage easy separation.

DETAILED DESCRIPTION OF THE INVENTION

[0020] An improved adhesive-type weight system 100 for use with wheels 20 and tires 10 includes one or more weights 110 arranged in series as shown as shown in FIGS. 1-2. Each weight 110 is formed of a flexible thin iron plate material preferably having a substantially rectangular perimeter with opposing first and second lateral ends 130a, 130b and first and second opposing lateral sides 132a, 132b. Preferably, first lateral end 130a is substantially parallel to second lateral end 130b, and first lateral side 132a is substantially parallel to second lateral side 132b. Alternatively, each weight may have a perimeter that is non-rectangular such that one or both of lateral ends 130a, 130b are not parallel to one another and lateral sides 132a, 132b are not parallel to one another. Although iron is preferred, weight 110 can be formed of a flexible lead, zinc, zinc, or metal alloy, all of which falls within the scope of this invention. Preferably, weight 110 is connected to additional weights 110 along its ends 130a and 130b or arranged in a series with additional weights 110 sitting adjacent to one another along its ends 130a and 130b. Alternatively, weight 110 may be a singular weight 110 for application to wheel 20 as shown in FIGS. 3 and 4, or the series of weights 110 may be arranged along their sides 132a and 132b as shown in FIG. 8. Preferably, each weight 110 is about 0.25 ounces but smaller or larger weights can also be configured according to the present invention.

[0021] Each weight 110 includes a first planar section 112, a second planar section 114, and a raised center section 116 disposed between the first planar section 112 and second planar section 114, as shown in the Figures. The proximal end of first planar section 112 is the first lateral end 130a of the overall weight 110, and the distal end 130c of first planar section connects to center section 116. The proximal end of second planar section 114 is the second lateral end 130b of the overall weight 110, and the distal end 130d of second planar section connects to center section 116. Preferably section 112 is integrally connected to center section 116 along the distal end 130c of first planar section 112. Likewise, preferably section 114 is integrally connected to center section 116 along the distal end 130d of the second planar section. Also preferably, center section 116 forms a peak 116a as shown in FIGS. 1-8. Alternatively, center section 116 can be an arch, a step, or another configuration as long as it creates an open space below it relative to first and second planar sections 112 and 114. FIG. 9 illustrates some examples of alternate configurations for center section 116 of each weight 110. The peak, arch, step, or other raised configuration of center section 116 preferably uniformly extends from first lateral side 132a to second lateral side 132b. Alternatively, the peak, arch, step, or other raised configuration of center section 116 can taper from one height to another across weight 110 as shown in FIG. 10.

[0022] For each weight 110, one or more adhesive units 120 connects or preferably covers at least the lower surfaces 112a and 114a of planar sections 112 and 114. Adhesive units 120 allow each individual weight 110 to attach to a wheel of a vehicle. More preferably, when weights 110 are not attached to the wheel of a vehicle, release paper 140 covers the adhesive units 120 to protect the adhesive units 120. Release paper 140 is removed immediately prior to bonding the weight 110 or series of weights 110 to the wheel. Adhesive units 120 can be a series of separate adhesive units 120 that are individually bonded to the underside or lower surfaces 112a, 114a of each planar section 112 and 114 of weight 110 as shown in FIG. 3 or a continuous sheet of adhesive that supports a series of weights 110 as shown in FIG. 5. Preferably, no adhesive unit 120 directly contacts the underside of center section 116 where it is raised as is shown in the Figures. Alternatively, it can be applied to the underside or lower surfaces of the entire weight 110 including to the lower surface (not labeled) of center section 116. Release paper 140 can be a series of individual release papers applied to individual weights 110 or a continuous release paper 140 applied to a series of weights 110.

[0023] Where weights 110 are arranged in a series, they may be separate and distinct weight that abut or are adjacent to other weights or they may be at least partially attached or connected where they abut one another. If partially attached, preferably a score, notch, or cut extends along the union to define the connection point and allow a user to easily disconnect one weight 110 from another. FIG. 6 illustrates a configuration of weights 110 in series, arranged in an end-to-end manner, where the weights sit adjacent to each without being attached. FIG. 5 illustrates a configuration of weights 110 in series, arranged in an end-to-end manner, where the weights are connected with a notch or partial cut extends along and defines adjacent ends 130a, 130b. As shown, when weights are arranged end-to-end, the first lateral end 130a of one weight preferably abuts the second lateral end 130b of an adjacent weight, especially when the individual weights 110 have a substantially rectangular perimeter. Should the weights have a non-rectangular perimeter, they may be arranged differently. For example, a series of weights with a triangular or isosceles trapezoidal perimeter may be arranged so that the first lateral end 130a of a first weight abuts the first lateral end of a second weight, the second lateral end of a second weight abuts the second lateral end of a third weight, and the first lateral end of the third weight abuts the first lateral end of a fourth weight. FIG. 11 illustrates such an arrangement.

[0024] To use weights 110, a technician removes the release paper and then applies as many weights 110 as needed to balance the tire. When weights 110 must be removed, a technician places the end of a tool, such as the end of a flat-head screwdriver, under the center section 116 of one of weights 110. Using a rubber mallet, the technician can tap on handle of the screwdriver to apply force under the center section 110. This overcomes the strong adhesive bond between weight 110 and wheel 20 and encourages the weight 110 to lift off the wheel surface. The technician can quickly and simply move the screwdriver and mallet to the next center section 116 and continue releasing individual weights. Because each weight 110 has a raised center section 116, they can be quickly and easily removed, which improves a technician's efficiency.

[0025] While there has been illustrated and described what is at present considered to be the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made and equivalents may be substituted for elements thereof without departing from the true scope of the invention disclosed, but that the invention will include all embodiments falling within the scope of the claims.
