Description
FIELD OF THE INVENTION

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.


BACKGROUND OF THE INVENTION

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.


SUMMARY OF THE INVENTION

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.


Other objectives and aspects of the invention will become apparent from the following detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the features in accordance with embodiments of the invention. The summary is not intended to limit the scope of the invention, which is defined solely by the claims attached hereto.

The stoppers 107 along with the bracket 112 disposed at the top surface 106 of the panel 104 of the elevated base 102, enables a discharge and the sprayer 114 to be retained securely in a desired position for targeted cleaning of the footwear sole 200. In one embodiment, the sprayer 114 is detachably attached to the bracket 112 and the sprayer 114 is hold in a desired position by the bracket 112 and the one or more stoppers 107 on the panel 104 in a snap fit relationship. Though other connectivity means may be used to detachably attach the spray head 122 to the elevated base 102. Further according to an exemplary embodiment, the elevated base 102 has a generally square shape; however other shape and design of the elevated base 102 can be used without departing from the scope and spirit of the present invention. Suitable materials for the elevated base 102 may include, without limitation, a polymer, lightweight metal, a metal alloy, rubber, wood, and fiberglass.


Those skilled in the art will recognize that the cleaning fluid 202 for removing debris from the footwear sole 200 can include water, water and soap solution, alcohol, air or combinations thereof. Other cleaning fluids 202 may, however, also be used in further embodiments including warm or hot solutions.


As FIG. 9 and FIG. 10 illustrates close-up view of the elongated hollow body 116 of the sprayer 114. The body 116 may include a stainless steel composition that inhibits rusting, however other rust proof materials can be utilized without departing from the scope and spirit of the present invention. FIG. 9 illustrates open (non-operational) position of the stepper (not shown) when the device 100 is not in use; thereby showing only the spray trigger 132 on the elongated hollow body 116 of the sprayer 114. FIG. 10 illustrates closed (operational) position of the stepper 123 when the device 100 is in use however; thereby showing the foot trigger 124 in a desired position over the spray trigger 132. In one exemplary embodiment, the spray trigger 132 is spring biased. In this manner, pressing the foot trigger 124 by the footwear sole 200 presses the spray trigger 132 for actuating discharge of the cleaning fluid from the spray head 122 through the central hollow area 127 of the foot platform 126 to provide a hands-free cleaning of the sole of the footwear 200.


In one non-limiting embodiment as shown in FIG. 1 and FIG. 11, the foot platform 126 of the stepper 123 comprises an annular surface 129. The annular foot platform 126 comprises a central hollow area 127 configured to expose the spray head 122 towards a footwear sole 200 of a user, the footwear sole 200 is placed on the annular surface 129 of the foot platform 126 allowing the pressurized stream of cleaning fluid 202 from the spray head 122 to thoroughly clean crevices and traction on the bottom of the footwear sole 200 without using the hands. The foot platform 126 more specifically has a doughnut shape that is sized and dimensioned to receive a region of the bottom of the footwear sole 200. This annular shape allows for a more targeted cleaning of the bottom of the footwear sole 200 while preventing splashing of the cleaning fluid 202. Other shapes of the foot platform 126 including a square shape, a rectangular shape, and a pyramid shape can be used without departing from the scope and spirit of the present invention however. The foot platform 126 may be textured or fabricated from rubber or other flexible material, so as to help inhibit slippage of the footwear sole 200 while pressing down on the foot platform 126.


As shown in FIG. 12A-B and FIG. 1, the legs 128 that extend from the cylindrical side wall 125 of the stepper 123 are configured to be positioned on the panel 104 of the elevated base 102 while the stepper 123 is maintained in a position by aligning a slot 131 of the cylindrical side wall 125 with the elongated body 116 of the sprayer, wherein the slot 131 may be the gap between two consecutive legs 128 extended from the cylindrical side wall thereby allowing he foot trigger 124 to remain in a desired position over the spray trigger 132. The legs 128 rest on panel 104 of the elevated base 102 to provide support for the stepper 123 when the user places the footwear on the foot platform 126 of the stepper 123, while the foot trigger 124 engages the spray trigger 132. This allows the foot trigger 124 to fully press down onto the spray trigger 132 for actuating discharge of the cleaning fluid 202 from the spray head 122 through the central hollow area 127 of the foot platform 126 to provide a hands-free cleaning of the footwear sole 200. The cylindrical side wall 125 of the stepper 123 directs the cleaning fluid 202 to flow within the central hollow area 127 of the foot platform 126 and prevents splashing the cleaning fluid 202 other than the footwear sole 200. After cleaning the sole of the first footwear, the user can then place the second footwear on the device 100 and clean the sole of the second footwear in the same manner.


In an exemplary embodiment as shown in FIGS. 1, 10 and 12A, the one or more legs 128 of the cylindrical side wall 125 rest on the panel 104 when the foot trigger 124 is fully pressed, thereby preventing excess pressure on the spray trigger 122.


In another exemplary embodiment, the foot trigger 124 or cylindrical wall 125 can be made of flexible material, thereby allowing the foot trigger to be pressed to bend the foot trigger 124 to a desired angle to press the spray trigger to a desire position as per the flow intensity of the cleaning fluid 202 desired by applying the subsequent amount of foot pressure by the user on the foot trigger 124. Further, any such modification to the design for controlling the pressure on the spray trigger 122 can be achieved without departing from the scope and spirit of the present invention.


In an exemplary embodiment, the annular surface 129 is sloped towards the spray head 122 such that the discharged cleaning fluid 202 and debris from the footwear sole 200 flow freely within the cylindrical wall 125 of the stepper 123 and beneath the elevated base 102 as shown in FIGS. 1, 2, and 11, so as to facilitate a user to place the shoe in a desired position while cleaning the footwear sole 200 by the discharged cleaning fluid 202 and allowing the discharged cleaning fluid 202 and debris from the footwear sole 200 to flow freely within the central hollow area 127 of the cylindrical side wall 125 of the stepper 123 and beneath the elevated base 102 through the multiple apertures 108 in the elevated base 102, thereby preventing splashing of the cleaning fluid 202 and the debris (FIG. 12A). The user can press down with different sections of the footwear sole 200 to clean the respective section of the footwear sole 200 while pressing the foot trigger 124 by pressing the foot platform 126 from any suitable direction (FIG. 12B). And as discussed above, intensity of the cleaning fluid 202 can be adjusted to accommodate different cleaning needs and footwear sole types.



FIGS. 13A and 13B illustrate perspective views of the device 100 showing that the sprayer 114 of the device 100 can be used to clean the device itself. This self-cleaning feature is possible because the spray head 122 detaches from the bracket 112 on the base 102. FIG. 13A shows the foot trigger 124 being pivotally displaced away from the base 102, which also serves to move the device 100 to an open (non-operational) position. FIG. 13B shows the sprayer 114 detached from the base 102 and spraying the cleaning fluid 202 on to the stepper 123 and the base 102. In this manner, debris from the footwear sole 200 is removed from the base 102 and the stepper 123. The cleaning fluid 202 flows beneath the elevated base 102 during self-cleaning, as in cleaning the footwear sole 200. It is significant to note that when the sprayer 114 is detached from the base 102, the spray trigger 132 is depressed with the hands of the user for cleaning the device 100. Further the sprayer 114 can be used for other cleaning purposes such as watering plants and the like. The device 100 is portable by allowing the stepper 123, the base 102 and the sprayer 114 dissembled to be carried separately for easy and quick transportation to a golf court, construction site or the like as per the user's requirement.
