1. Field of the Invention
The present invention relates generally to vehicle repair and in particular to an apparatus for reconditioning disfigured wheels.
Within the vehicle repair industry, and in particular within the wheel repair market, the need exists to employ devices to salvage disfigured wheels. Conventionally wheels made of steel have been used for vehicles on which a tire is mounted about the wheel. Recently, however, new lightweight metals and metal alloys, such as aluminum, magnesium, and titanium, have been used for vehicle wheels. These new metals contribute to improved fuel efficiency, a more comfortable ride, and enhanced aesthetics. However, these wheels are frequently disfigured as a result of accident, such as the wheels coming into contact with curbing, encountering potholes in the roadway, rubbings against vehicle wash railings, and the like. While disfigured wheels were conventionally discarded, technology has improved within the vehicle repair industry that the disfigured wheels can now be reconditioned in many cases.
2. Description of Related Art
Various devices have been employed to recondition disfigured wheels. Examples of such devices are described in U.S. Pat. Nos. 3,855,831, 5,634,361, and 6,367,303. Most of the conventional devices used for reconditioning disfigured wheels employ a shaft support mechanism as a way to support the vehicle wheel during the reconditioning process. In addition to the shaft support mechanism, many of these conventional devices also contain an additional support column attached to the shaft support mechanism with bearings that allow the wheel to rotate during the reconditioning process. While the shaft support mechanisms initially support the wheel during the reconditioning process, the repeated stress of the forces applied to the wheel during the wheel reconditioning process eventually causes the shaft support mechanisms to become disfigured and fail for their intended purpose. The repeated stress of the forces applied to the wheel during the reconditioning process also cause the bearings to become disfigured so that the additional support column no longer rotates with ease. These problems with the conventional devices cause costly repair or replacement of the conventional wheel reconditioning devices.
For example, in U.S. Pat. No. 3,855,831 a wheel is mounted on the repair apparatus on a central shaft support mechanism. The central support mechanism supporting the wheel includes a perpendicular rotatable shaft support mechanism at the top of the central support mechanism that is supported by bearings to allow the wheel to spin during the repair process. The wheel is locked onto the rotatable support mechanism by bolts through the normal mounting holes of the wheel hub.
Under repeated stress from perpendicular or near perpendicular forces used to repair disfigured wheels, these shaft support mechanisms and the bearings supporting an additional support column used to rotate the wheel tend to become disfigured. When the shaft support mechanism or the bearings supporting an additional support column of a wheel repair device are disfigured, the wheel repair device can no longer be relied upon to return a wheel to its true form. The repair devices then must undergo costly replacement of the shaft support mechanism and the bearings supporting the additional support column or, in many instances, replacement of the wheel repair apparatus itself.
A need exists, therefore, for a wheel reconditioning apparatus that will support a disfigured wheel during the reconditioning process wherein the wheel is supported by the apparatus without using a shaft support mechanism. Such apparatus should support the disfigured wheel under forces used during the wheel reconditioning process to return the wheel to its true form. The apparatus should also provide for improved bearings and support of the bearings so that the apparatus is rotatable to allow the portion of the wheel that is disfigured to be reconditioned to its true form. Finally, the apparatus should allow for a variety of widths and diameters of the wheels so that the apparatus can be used to recondition any size wheel.

The problems presented with the wheel repair devices are solved by the apparatus of the present invention. In accordance with one embodiment of the present invention, a wheel reconditioning apparatus is provided. The apparatus includes a support frame upon which a base support plate is attached. A rotatable adapter plate is supported on the base support plate by a precision bearing for supporting the rotation of the adapter plate about the vertical axis of a mounted wheel. Adjustable wheel chucks are set in place on a chuck base that is set in place on the adapter plate. The disfigured wheel is mounted between the adjustable wheel chucks and held in place by the wheel chucks during the reconditioning process.
In accordance with another embodiment of the present invention, a wheel reconditioning apparatus is provided with a chuck apparatus fixed to an adapter plate that is rotatable in concert with the adapter plate about the fixed vertical axis of a wheel mounted on the wheel reconditioning apparatus. The adapter plate and chuck apparatus are fixed to mounting blocks and are supported on a base support plate by a precision bearing for supporting the rotation of the upper base and chuck apparatus. The base support plate is fixed to a support frame. The chuck apparatus includes a threaded insertion whereby a fitted bolt inserted into the threaded insertion in the chuck apparatus and turned causes the chuck slides on the chuck apparatus to move to the desired fit of the diameter of the rim of wheel.
In accordance with another embodiment of the present invention, wherein a chuck apparatus with threaded insert is included to move the chuck slides to the desired fit of the diameter of the rim of the wheel, it is possible to include a support for a pneumatic wrench on the adapter plate fitted so that a fitted bolt can be inserted into the threaded insertion of the chuck apparatus with pneumatic pressure from a pneumatic wrench.
In accordance with another embodiment of the present invention, the support frame includes a vertical support shaft that supports a hydraulic arm used to apply pressure to the disfigured wheel. Attached to the hydraulic arm is a ram that has a rounded edge in the approximate original form of the disfigured wheel. The vertical support shaft can be grooved so that the hydraulic arm is adjustable in a vertical direction and spring loaded into a groove along the vertical support shaft at the desired height.
Other objects, features, and advantages of the present invention will become apparent with reference to the drawings and detailed description that follow.
All references cited herein are incorporated by reference to the maximum extent allowable by law. To the extent a reference may not be fully incorporated herein, it is incorporated by reference for background purposes and indicative of the knowledge of one of ordinary skill in the art.

The adjustable wheel chuck 9 is fixed to the base chuck 8 with a pin 14 inserted through a hole in the adjustable wheel chuck 9 and matched to a hole in the base chuck 8. Each base chuck 8 is attached to a chuck slide 15 of the chuck apparatus 6 that can be moved laterally by the insertion of a fitted bolt in the threaded insertion 16. When a fitted bolt is entered into the threaded insertion 16 of the chuck apparatus 6, the chuck slides 15 will move laterally causing the adjustable chuck assembly 12 to either move toward or away from the wheel H (as shown in
According to an embodiment of the present invention, as shown in
One skilled in the art will see that the present invention can be applied in many areas where there is a need to provide sturdy support during the wheel reconditioning process. For example, while an embodiment of the present invention uses a hydraulic arm with an attached ram to recondition the wheel, one skilled in the art will know that other methods can be employed to recondition a wheel using the present invention. It is well known in the art that for slight disfigurement, specialized hammers and wrenches are often used to recondition wheels. Additionally, in cases of serious disfigurement, heat is often applied to the wheel, through the use of a gas burner or blowtorch, before reconditioning the wheel to soften the metal before a usual hydraulic force is pressed against the rim. The present invention provides the necessary support for these methods of reconditioning a wheel without damage to the wheel reconditioning apparatus.
It should be apparent from the foregoing that an invention having significant advantages has been provided. While the invention is shown in only a few of its forms, it is not just limited but is susceptible to various changes and modifications without departing from the spirit thereof.
