BACKGROUND OF THE INVENTION
1. Technical Field
This invention relates to a cleaning device and, more particularly, to a portable vehicle rim cleaning device.
2. Prior Art
As is well-known in the art, many devices and tools exist for assisting in the cleaning of car rims, mag-wheels, and the like. Arising from the inherent problems and inadequacies associated with a common sponge or washcloth, these devices have been developed to solve a variety of particular problems associated with the cleaning of these objects that have complex and intricate shapes.
More specifically, cleaning devices such as brush cleaning devices for single specialized purposes are known in the art. However, in order to have the benefit of a multiplicity of these specialized cleaning devices, one must purchase each of these specialized devices at significant combined cost. Further, upon purchasing all of these specialized devices, significant storage area must be dedicated to storing all of the specialized devices. Still further, maintaining each of the devices and toting the devices around during cleaning chores poses further challenges to the use of these individual devices.
Accordingly, a need remains for a rotatable wheel rim cleaning device in order to overcome the above-noted shortcomings. The present invention satisfies such a need by providing a wheel rim cleaning device that is easy to use, results in time and effort savings, is small and compact in size, portable, and effectively cleans rims in an easy manner. Such a device eliminates the need to polish and clean a vehicle's wheel rims manually, while also retaining the option to attach alternate cleaning tools to the device.
BRIEF SUMMARY OF THE INVENTION
In view of the foregoing background, it is therefore an object of the present invention to provide a rotatable vehicle rim cleaning device. These and other objects, features, and advantages of the invention are provided by a hand-operable brush for cleaning the crevices of vehicle rims.
The brush includes a hollow handle section having a plurality of adjacent internal compartments and a substantially cylindrical shape. Such a handle section is provided with a centrally disposed longitudinal axis further having proximal and distal end portions oppositely spaced along the axis. The handle section includes a cap removably attachable to the proximal end portion for conveniently allowing a user to access one of the compartments thereof. Such a handle further has an outer surface provided with a plurality of linear grooves extending substantially parallel to the axis for advantageously assisting an operator to maintain a sufficient grip of the brush. The distal end portion is provided with an outlet in fluid communication with the compartments.
A variable speed motor is disposed within another of the compartments and includes an elongated drive shaft extending axially and distally therefrom. Such a motor further includes a switch operably connected thereto for allowing a user to selectively toggle the brush between operating and non-operating modes.
The device also includes a cleaning section including a driven shaft operable via the motor and extending distally away from the handle section. Such a cleaning section includes a plurality of bristles preferably having a plurality of cores annularly spaced about the axis and extending radially away from the driven shaft. The plurality of bristles are axially rotatable at alternate speeds and directions. The driven shaft preferably includes a plurality of first portions radially spaced therefrom and extending substantially orthogonal to the axis. Such a driven shaft further includes a plurality of resilient second portions spaced therefrom and integrally attached to the first portions respectively. The second portions extend substantially parallel to the driven shaft wherein the bristles are attached to the second portions respectively and are axially offset from the axis for advantageously adapting to a general shape of a vehicle rim fastening member.
In an alternate embodiment, the driven shaft may have a substantially smooth outer surface provided with a hollow distal end portion for defining a cavity. The bristles are randomly spaced along the outer surface wherein the bristles radially extend inwardly and outwardly from the outer surface so that the hollow distal end portion can be selectively positioned about a vehicle rim fastening member during operating conditions. Such bristles are preferably sized and shaped to be substantially linear.
The present invention further includes a coupling member axially positioned adjacent to the distal end portion. Such a coupling member is provided with a plurality of isolated channels sized and shaped for receiving the drive shaft and the driven shaft so that the cleaning section and the motor will contemporaneously rotate at the selected speed and direction. The drive shaft, the driven shaft, and the coupling channels all preferably have corresponding hexagonal cross-sections. A power supply source including a plurality of batteries is housed within one compartment and is electrically coupled to the motor.
