Description
TECHNICAL FIELD
[0001] The present invention relates generally to portable spray
devices and, more specifically, to a portable spray car wash device
capable of holding and dispensing liquid cleansers and waxes for
rubbing into the body and windows of a vehicle, thereby enabling
complete washing and cleaning thereof. The present invention is
particularly useful in, although not strictly limited to,
automobile detailing applications desiring portability of equipment
and materials for mobile washing and cleaning services.
BACKGROUND OF THE INVENTION
[0002] The purchase of an automobile represents a considerable
expense. For most individuals, even the expense of an economy car
can be substantial. However, despite rising sticker prices and
increases in fuel costs, luxury and sports automobiles continue to
be sought after. Thus, the prestige of driving an attractive car
endures.
[0003] Some car and truck owners enjoy individualizing their
vehicles by purchasing specialty paint jobs, stylish wheels, chrome
accessories and ornamental lighting packages. Others prefer to
maintain their car, truck, sport utility vehicle (SUV) or van as
close to factory issue as possible. Many rely on routine cleaning
and maintenance to maximize their enjoyment, as well as the life of
their car.
[0004] Cleaning and detailing a vehicle instantly improves its
appearance. Owners maintain a sense of "new car" appreciation with
a clean interior. A shining exterior, on the other hand, conveys a
sense of pride to all who see it. Whether luxury or economy, a car
with a freshly cleaned and waxed body and spotless windows is to be
admired.
[0005] Unfortunately, cleaning and detailing a car, truck, SUV or
van is a time-consuming and labor-intensive endeavor. Automatic car
wash facilities have become increasingly available, with many
directly associated with fueling stations. These automated
facilities do provide convenience, however are unable to offer
detailed cleaning. Hand wash and detail centers offer detailing and
hand cleaning, however sacrifice some of the convenience. Since
hand cleaning necessarily requires more time than an automatic car
wash, the vehicle owner must either make an appointment to leave
his or her car, or must wait while the job is completed.
[0006] One recently introduced alternative wherein the benefits of
hand cleaning and detailing are combined with total convenience is
mobile detailing service. Such a service travels to the vehicle,
either at home or place of business, and completely cleans and
details the car while it is parked and otherwise unneeded. These
mobile detailing service professionals utilize a variety of
cleaning tools, solutions and products and must transport them to
each location.
[0007] Devices have been introduced to enable various mobile
cleaning applications. One type of mobile cleaning apparatus, such
as described in U.S. Pat. No. 3,680,786 to Levy and U.S. Pat. No.
4,967,960 to Futrell, connects to a water source thereby enabling
the selective spray application of a cleaning solution entrained in
water or water for rinsing. The disadvantageous reliance of this
type of device on an external water source limits its true mobile
usability. Other devices, such as described in U.S. Pat. No.
3,797,744 to Smith and U.S. Pat. No. 5,064,123 to Aiello, et al.,
further limit their portability by depending upon external power
and air supplies, often in addition to a water source. Such
limitations inhibit truly moveable use.
[0008] Alternative types of mobile cleaning apparatus' are
described in U.S. Pat. No. 5,029,758 to Chayer, U.S. Pat. No.
4,089,446 to Logan, U.S. Pat. No. 3,831,849 to Studinger and U.S.
Pat No. 4,546,903 to Burch. These devices still depend upon water,
however, provide an on-board water supply tank, thus eliminating
the need to connect to an external water source. Some also have the
ability to rely on battery power to enable free movement. However,
the tank size, in addition to the considerable weight of multiple
gallons of water, disadvantageously inhibits true portability and
maneuverability.
[0009] Therefore, it is readily apparent that there is a need for a
portable spray car wash device enabling complete detailing of a
vehicle without the use of water, wherein cleansers and waxes for
rubbing into the body and windows of a vehicle are held and
dispensed thereby, thus preventing the above-discussed
disadvantages.
