The present invention relates generally to automotive detailing devices and more particularly to wheel polishing device configured to be coupled to a wheel polishing stand.
A wheel polishing stand or wheel detailing stand is a detailing product that allows a wheel to be attached such that the wheel may be rotated to make the detailing or cleaning process easier. Generally, the wheel may also include the tire. When polishing forged wheels, damage could occur to the wheel when attaching it to the wheel polishing stand. The wheel polishing devices of the prior art feature sharp teach or poor designs which lead to wheel damage. Consequently, a solution is needed.
The following presents a simplified summary of some embodiments of the invention in order to provide a basic understanding of the invention. This summary is not an extensive overview of the invention. It is not intended to identify key/critical elements of the invention or to delineate the scope of the invention. Its sole purpose is to present some embodiments of the invention in a simplified form as a prelude to the more detailed description that is presented later.
It is a main object of the present invention is to provide a wheel polishing device configured to attach to a wheel polishing stand suitable for forged wheels, and particularly smaller forged wheels. It is another object of the present invention to provide a wheel polishing device configured for use with a mechanical human powered system, i.e. no electric motors or electronics. It is yet another object of the present invention to provide a portable system.
In order to do so, a wheel polishing device configured to couple with a wheel polishing stand is provided, the wheel polishing device comprising a base plate member defining a plurality of tracks; a plurality peg members, wherein each of the plurality of peg members are configured to slidably engage a track of the plurality of tracks defined by the base plate member; and a peg expanding hub positioned centrally approximate to the base plate member, the peg expanding hub having a central aperture and an internal seat; a center screw configured to pass through the central aperture of the peg expanding hub; a nut configured to rotate on the center screw and engage the internal seat, wherein the nut is configured to push the internal seat and the peg expanding hub downwardly toward the base plate member, which pushes the plurality of peg member outwardly along the tracks such that the plurality of peg members are configured to engage an inner piloting diameter of a wheel to secure the wheel to the wheel polishing device.
In one embodiment, the rotational movement of the nut along the center screw in a downward direction moves the plurality of pegs in an outward direction, against an inwardly directed force created by one or more biasing members. In another embodiment, the rotational movement of the nut along the center screws in an upward direction moves the plurality of peg members in an inward direction. In one embodiment, the base plate member comprises three angled tracks that are machined at 120 degree increments about a circumference of the peg expanding hub. In another embodiment, the plurality of peg members is 3. In one embodiment, at least one of the plurality of peg members define one or more cavities to removably engage at least one biasing member. In yet another embodiment, the one or more cavities are defined along an outer surface of each peg of the plurality of peg members. In one embodiment, each peg of the plurality of peg members comprises an incline surface positioned against a matching incline surface on the peg expanding hub. In another embodiment, the downward force of the nut on the internal seat engages the matching incline surface of the peg expanding hub along at least a portion of this incline surface of the plurality of peg members, such that each of the plurality of peg members moves along one of the plurality of the tracks. In another embodiment, the incline surface extends only along a portion of a surface of each peg of the plurality of peg members. In one embodiment, the peg expanding hub is cylindrical. In another embodiment, each peg of the plurality of peg members defines a width associated with a specific inner diameter range of the inner dimeter of the piloting diameter of the wheel. In yet another embodiment, the plurality of peg members may be exchanged with an alternative set of plurality of peg members having a second width such that the wheel polishing device may be used with other inner diameter ranges of different wheel's piloting diameters. In one embodiment, the wheel polishing stand is manually powered.

In one embodiment, a bearing member (wheel hub assembly) 115 is configured to be secured to the interchange support member 004 via connection bolts 005 into corresponding bolt holes 102, wherein the bearing member 115 is configured to rotate about the support member 004. A backing plate member 118 is configured to couple to the bearing member in any method known in the art. A centrally threaded rod or center screw 30 is configured to pass through a center hole 103 of the backing plate 118. The details of the center screw 30 will be discussed in further details below. A base plate member 105 is configured to be coupled to the backing plate member 118, wherein the base plate member is preferably circular. In one embodiment, the base plate member 105 is coupled to the backing plate member.
The details and components of the wheel polishing device will be discussed, but its purpose is to hold, grip, or clamp a wheel or rim (with or without a tire) such that it may be rotated via the wheel polishing stand 001. The wheel polishing device of the present invention is configured to hold the wheel via the wheel's center hole or piloting diameter. During use, a wheel is rotated, via the wheel polishing stand 001 manually by a user, facilitating an ease of detailing the wheel. More specifically, the wheel polishing stand 001 is configured to lift the wheel off the ground. The user can then use a grinder with an airway attached to polish the rim with polishing compound or rouge. Further, since the mounted wheel can spin freely on the wheel polishing stand, a rotational motion of a user's grinding wheel will rotate or turn the mounted tire or mounted wheel.
For example, in one embodiment, a rotational movement or rotational motion of the polishing wheel stand and the angle of pressure transfer to the wheel creates a motion that rotates the wheel for a controlled and even polish or the wheel may be manually rotated via turning, or other means configured to rotate the wheel. The interface between the wheel to be serviced and the fixed wheel stand is the wheel polishing device 100. A first end of this system 100 comprises the bearing member allowing rotation about the fixed stand. In one embodiment, the bearing member is a wheel hub assembly. A second end of the devices interfaces with the wheel is of an expanding design that can be used to clamp the wheel both axially and radially. Advantageously, the present invention is configured to clamp a soft forged wheel, such as constructed from aluminum, without damaging the wheel during the process.

In this illustrated embodiment, three pegs 120A are utilized. For example, the plurality of pegs may comprise three pegs, wherein each of the three pegs is positioned equally distant from one another along the first surface 114 of the base plate member 105. However, those of ordinary skill in the art will recognize, alternative clamping fingers or clamping member arrangements may also be utilized.
As illustrated, the second surface 128 comprises a generally smooth, linear surface. However, alternative surface configurations may also be used. As just one example, the second surface 128 may comprise a convex surface. As previously mentioned, the device, and more particularly the plurality of tracks are configured to receive different sized pegs. These different sized pegs may be selected to grip or mount different sized wheels to a wheel polishing stand, such as the wheel polishing stand 001 illustrated in
In one embodiment, the first surface 130 is a machined incline 130. For example, as illustrated in
In operation, in one embodiment, the angle of the expanding hub 160 to the inclined surface 130 of the peg creates a frictional locking force. Less of an angle would not create the required increase of diameter to effectively reach the diameter range required. A steeper angle may increase the diameter range however it would interface at an angle that would not stay tight.
As previously noted, the wheel polishing device 100A illustrated in
In one embodiment, the peg expanding hub 160 is configured to be used with a nut 180. The nut 180 may be configured to threadedly engage the threaded rod or center screw 30. For example, as illustrated in
The biasing members or elastic bands allow for the expansion of the pegs radially about the peg expanding hub 160 as the nut is tightened on the center screw 30. Similarly, the biasing members 200 and 210 allow for the retracting of the pegs when the peg expanding hub 160 and nut 180 are reversed.
For example, as the nut 180 is threadedly engaged to the center screw 30, as the nut 180 is rotated in a clock-wise direction this will exert a downward force on the machined incline surfaces 130 on the peg. This downward force will cause the plurality pegs to expand away from another, away from the peg expanding hub 160 and nut 180. As the nut 180 progresses along the center screw 30, the pegs continue to expand radially outward along each respect track defined by the base plate member 105. For example, as the nut 180 is seated within the peg expanding hub 160, an outer cylindrical surface of the peg expanding hub 160 acts upon the inclined surfaces 130 of the peg while the pegs extend radially outwardly along their respective tracks, and away from the peg expanding hub 160.
As the pegs are expanded, a lower feature of each of the peg interface with another radially extending away that provides support opposing the torsional forces that the pegs may see as the wheel is being polished or reconditioned. To accommodate a variety of wheel center openings or piloting diameters, a user can interchange the peg size and retaining bands. The interface with the expanding peg hub 160 and/or nut 180 does not need to be exchanged.
