The present invention relates generally to a footwear sole cleaning device and method. More so, the present invention relates to a hands-free and portable footwear sole cleaning device comprising a detachably attached sprayer for enhanced cleaning of the bottom of the footwear sole, self-cleaning the device, cleaning the surrounding area or the sides of the footwear and its method of operation.
Those skilled in the art will recognize that shoes and other footwear are exposed to various contaminants including, sand, dirt, mud, fecal matter, construction waste, garbage, or other noxious substances. Perhaps the most odious example is animal excrement, such as dog feces, or cow dung, but mere dirt and earth often cakes and collects on the bottom of footwear, such as the boots of a person working in a garden or the shoes of a person walking on a muddy trail. These contaminants are tracked into buildings when a person wearing soiled shoe enters them. It is unacceptable to have large “globs” of soil, particularly excrement, accumulate on the doormat, for example, where it may be tracked through the entryway and into the buildings by subsequent users; cleaning doormats, in turn, is a notoriously difficult and unpleasant task.
Using a conventional water hose to clean a shoe sole is not practical because it typically dampens the shoe upper and splashes water and contaminants onto the user. Numerous shoe and foot cleaning devices include means for producing a wide or panoramic spray pattern, which would wet both the shoe and the wearer. Other types of such apparatus employ rotating brushes powered from an electrical power source or stationary brushes.
Shoe cleaning devices using liquids such as water offer several design challenges. Fundamentally, the device must contain and control the water sprays so they strike and clean the desired portions e.g., bottom and sides of the shoe without wetting the user's leg and other portions e.g., top of the shoe while using as little water as possible.
Numerous attempts have been made and several prior art devices are known for cleaning a footwear or more specifically a footwear sole. Even though these innovations may be suitable for the specific purposes to which they address, however, they would not be as suitable for the purposes of the present invention.
For example, U.S. Pat. No. 5,173,972 to Goodman discloses an automatic foot washer comprising a pressurized water source and a flexible valve hose, a grated actuating platform and an actuator lever that is operatively contacts the flexible valve hose to, when a person steps on the actuator platform, open the valve assembly and establish communication of the pressurized water source and the plurality of spray outlets to spray water through the plurality of spray holes over the grated actuating platform and onto a person's feet, ankles, and calves.
U.S. Pat. No. 5,964,959 to Bleth teaches a shoe cleaning device using liquid sprays and including a housing having a U-shaped opening. Crisscrossing, upwardly directed sprays then strike and clean the shoe bottom while downwardly directed side sprays clean the shoe sides. Any portions of the upwardly directed, crisscrossing sprays not striking the user's shoe are captured in the opposing side portions of the U-shaped opening and directed into the base portion.
U.S. Pat. No. 6,584,636 to Schlem describes a footwear cleaning apparatus that includes an upper frame for supporting the user to stand upright while cleaning footwear being placed over a foot platform on a lower frame. A hose directs water upwardly onto the footwear sole. The apparatus further comprises two side brushes, a scraper assembly for cleaning the sole and sides of the footwear.
U.S. Pat. No. 6,662,398 to Thompson discloses a hands free foot scrubber comprising a raised foot pad area having bristles on an upper surface and an enclosed refillable bladder containing liquid soap fitting within the under surface below the foot pad. Foot pressure causes soap to be released on to the foot pad to facilitate hands free feet cleaning. The mat includes water drain holes and suction cups on the bottom of the mat and bladder which hold the components in place.
U.S. Pat. No. 6,668,842 to Wilke et al. describes a method and apparatus for dispensing a fluid of mixed disinfectant and water in a spray to footwear of a worker, the apparatus comprises a housing including a base section, a platform attached to the base section, a fluid dispensing assembly coupled to the housing, and a fluid dispensing system of mixed disinfectant and water when a force is applied to the platform so that the spray of the fluid is dispensed onto the footwear.
U.S. Pat. No. 6,736,339 to Mayers teaches a device for cleaning footwear soles including an H-shaped base frame formed of hollow tubes having a vertical water inlet line upwardly extending therefrom at a predetermined angle to deliver multiple pressurized streams of water to effectively clean a user's footwear sole while minimizing splashing of a user or a user's shoe.
U.S. Pat. No. 7,500,488 to Long discloses an apparatus for removing soil from footwear comprising a spray nozzle connected to a plunger having a discharge opening in its upper end, so that stepping on the plunger actuates a flow of water there through. The nozzle includes a return spring that biases the valve back to the closed position when the plunger is released.
U.S. Pat. No. 7,725,974 to Hughes describes a cleaning and disinfecting system for footwear or feet. The system is automatically activated only when a person stands on the device. Optionally, a venturi component allows the addition of a cleaning or disinfecting fluid with the cleaning solution or water, further it comprises an optional brush on a wand provides cleaning to upper foot areas as required.
U.S. Pat. No. 7,877,826 to Franklin teaches a foot washing station comprising a foot platform; a valve connected to a water supply; an actuator operably coupled to the valve; opposing spray members having plurality of nozzles are downwardly directed to knock debris off the lower leg and foot of a user to thus wash the debris away in a hands-free operation.
U.S. Pat. No. 9,603,504 to Cruz et al. discloses a footwear cleaning apparatus that includes a box having an open top surface for receiving a piece of footwear; and a plurality of brushes arrayed within the box, a plurality of nozzles emit a pressurized spray of water at the footwear.
U.S. Pat. No. 9,622,642 to Braaten et al. teaches a device for cleaning of footwear in connection with use of construction site vehicles; the device comprises a water pump, nozzles and water pipe, an air compressor system, housing that receiving the footwear to be cleaned. The device uses a sensor to automatically flush the footwear with water via the water pump and immediately thereafter to blow the footwear dry with air from the compressor.
U.S. Pat. Application No. 2004/0230144 to Weinberger describes a cleaning and/or massage device, comprising suction cups to fix the footwear in a position and a hydraulic drive which can be connected to a multiway valve of a water supply line and drives a brush in a rotating manner.
U.S. Pat. Application No. 2010/0299828 to Shapiro describes a self-contained pressure activated foot washer comprising a basin having a plurality of dispensing heads; a water reservoir, an air compressor; and a pump. Water and air is combined and emitted though said dispensing heads to remove debris from said persons' feet into the bottom of the basin.
It is apparent now that numerous innovations that are adapted to footwear sole cleaning have been developed in the prior art and that they are adequate for various purposes. Furthermore, even though these innovations may be suitable for the specific purposes to which they address, accordingly, they would not be suitable for the purposes of the present invention as heretofore described. Thus a hands-free portable footwear sole cleaning device for enhanced cleaning of the bottom of the footwear sole and method of operation is needed.
The present invention relates to a footwear sole cleaning device that is actuated, hands-free, to clean the bottom of the footwear sole by pressing down on the device with the footwear sole, so as to discharge a cleaning fluid directly into the crevices and traction that form in the bottom of the footwear sole, and thereby remove debris that lodges inside the crevices and traction; whereby an elevated base enables support for the device and drainage of cleaning fluid; a sprayer is retained in the elevated base to carry cleaning fluid, and is disposed upwardly away from the base and towards the footwear sole; and a foot trigger is in communication with a spray trigger so that depressing the foot trigger with the footwear sole actuates the sprayer to discharge the cleaning fluid towards the bottom of the footwear sole with minimal splashing and debris dislodgement above the elevated base. With it, the user can easily and quickly clean dirt and other debris from the bottoms and sides of his or her footwear in an efficient and effective manner.
According to an aspect of the present invention, a hands-free footwear sole cleaning device is provided, the device includes a base comprising a panel defined by a top surface, a bottom surface, and multiple apertures formed in a spaced apart relationship through the panel, the base further comprising at least one mount member extending from the bottom surface of the panel to elevate the panel above the ground surface to a desired height, the base further comprising a bracket disposed at the top surface; a sprayer comprising an elongated hollow body for carrying a cleaning fluid having an inlet end for receiving the cleaning fluid and a discharge end for discharging the cleaning fluid, the body of the sprayer further comprising a pressure actuated spray trigger operational to actuate discharge of the cleaning fluid through the discharge end when the spray trigger is pressed, the discharge end of the sprayer comprising a spray head, wherein the spray head being detachably attached to the bracket on the top surface of the panel, whereby the intensity of the discharged cleaning fluid is adjustable by the amount of pressure applied by the user on the spray trigger; and a foot trigger hingedly joined to the panel of the elevated base at a hinge, wherein the foot trigger comprising a foot platform and multiple legs, the foot platform comprises a flat surface to help inhibit slippage of the footwear sole of a user, the legs rest on the panel and a slot between two consecutive legs allowing the stepper to be engaged with the body of the sprayer, thereby allowing the foot trigger to engage with the spray trigger while holding the foot trigger in a desired position, whereby pressing the foot trigger by a footwear of a user causes the foot trigger to press the spray trigger for actuating discharge of the cleaning fluid to clean the sole of the footwear.
In view of the foregoing, it is therefore an objective of the present invention to thoroughly clean the crevices and traction on the bottom of the footwear sole with a strong stream of cleaning fluid without using the hands.
Another objective is to spray the bottom of the footwear sole without splashing cleaning fluid or debris upwardly and onto the pant legs or upper extremities of the user.
Yet another objective is to prevent debris from falling into the spray trigger, thereby reducing the possibility of a malfunction of the spray trigger.
Yet another objective is to enable drainage of the cleaning fluid beneath the elevated base by elevating the base.
Yet another objective is to provide a sprayer that discharges cleaning fluid in a targeted manner directly onto the bottom of the footwear sole.
Yet another objective is to inhibit slippage of the footwear sole on the foot trigger through use of a textured foot base.
Yet another objective is to provide an inexpensive to manufacture footwear sole cleaning device.
By self-cleaning in such a manner, numerous advantages are possible. For one, subsequent footwear soles are provided with a clean foot base on which to depress the foot trigger and receive cleaning. Another advantage is provided by detaching the sprayer from the base. By detaching the sprayer to clean the base and the stepper, the sprayer trigger is outside of the wash area where the dirty water is falling. This helps to segregate the cleaning means from the sole engagement means of the device and thus prevents debris from falling into the spray trigger of the sprayer thus reducing the possibility of a malfunction of the spray trigger.
