## Background
This application claims the benefit of U.S. Provisional Patent Application No. 60/701,792 filed Jul. 22, 2005.


BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a foot shower and spray device for washing the lower legs and feet of a user, and more particularly to a foot washing station for use after leaving the beach or pool and/or prior to entering a pool.
2. Description of Related Art
A number of foot washing stations have been developed in the prior art. U.S. Pat. No. 2,654,894 shows a foot bath having this device has foot engaging portions 66 where a user stands while water is distributed “outwardly and upwardly”. Water collects within the upstanding walls 10 of the bath. When the user leaves the platform 66, the plug 63 moves away from the drainage port 17 to allow the bath to drain.
U.S. Pat. No. 2,641,771 is another foot washer which directs water through apertures or orifices 38 of spraying member 32 at the inserted feet of a user. Once again, handles 50,52 are utilized to start the process of providing water through the foot washer. This device also has a flat bottom tub 28 which would appear to tend to allow water to pool up and redistribute debris back onto the feet.
U.S. Pat. No. 3,416,178 shows a foot washer massager that does not have a spray capability except for the shower that it is used in. Also, the brush back plates 76 is also planar which could allow water to stand thereon thus allowing any debris floating on the water to once again adhere to the foot of the user.
U.S. Pat. No. 3,925,830 shows a hands-free foot shower and spray device. This device directs water from two opposing spray heads onto the foot of a user. This device has a flat top 71 with a slope 73 along its periphery to assist in draining water. However, from the appearance of this device there does not appear to be a mechanism to drain water from the flat top 71. Additionally, since water is directed only from two opposing stations, there is believed to exist the possibility of blind spots where debris may remain on the foot of a user. Finally, there does not appear to be any means to stop overspray so that a person walking by the unit is not hit with overspray of water by a person utilizing the device.
U.S. Pat. No. 4,918,779 shows a foot spraying cleaning device which directs water in between two brush assemblies. A foot actuated bar controls the flow of water onto the foot.
U.S. Pat. No. 5,964,959 shows a shoe cleaning device adapted to clean the bottom of the shoe and not the sides or the top of a foot.
U.S. Pat. No. 5,367,720 shows a foot washer apparatus which is activated without the use of hands. The actuator plate 24 may allow at least some water to pool around the user's feet.
U.S. Pat. No. 5,173,972 shows another automated foot washer which is activated by a person stepping on an actuating platform. The spray is directed at about the level of the feet in this device and there is no provision for stopping overspray.
U.S. Pat. No. 6,668,842 shows an apparatus and method for sanitizing and washing footwear with four spray nozzles at a common elevation.
While there have been numerous attempts to create an approved foot washing station, none of these prior art devices are believed to provide a satisfactory device for use in cleaning the lower leg of a person in addition to the feet such as would occur as a person is walking off the beach situation. Especially if the person's hands are full of umbrellas, towels, chairs and other assorted gear from carrying back and forth to the beach, hands free operation is particularly desirable in such an application.
SUMMARY OF THE INVENTION
A need exists for an improved foot washing station.
Another need exists for a foot washing station which incorporates advantages of the prior art and employs new technology to provide an improved foot washing station.
Another need exists for a foot washing station which directs water onto the legs and feet of the user in a hands free operation to dislodge sand or debris from the legs such as before entering a pool or after leaving a beach, etc.
Another need exists for a foot washing station having a plurality of jets located above the foot of the user at more than one elevation and in a non-linear arrangement so that a plurality of differently oriented streams of water spray and/or mist can be directed at the foot with at least some of them directed downwardly to wash debris, dirt, etc., away from the leg and foot of the user.
Accordingly, in the presently preferred embodiment of the present invention, a plurality of nozzles are located on each side of a foot washing station on spray members. At least some of the nozzles are downwardly directed to knock debris off the lower leg and foot of a user to thus wash the debris away. In order to most efficiently remove debris, the nozzles are preferably located at a plurality of elevations. At least some of the nozzles on each side are preferably non-linearly disposed relative to one another and are located at an elevation above the feet of the user.
The platform supporting the foot or feet is preferably continuously sloped so that water does not accumulate at any portion of the foot platform. Additionally, an actuator is preferably actuated by the placement of the weight of the foot on the foot platform to begin the spraying of the foot or feet with water in a hands-free operation. In the preferred embodiment, spray nozzle tips are screwed into manifolds which then dispense water under pressure preferably in a spray fashion with highly atomized water pellets efficiently removing debris from the feet of a user.

DETAILED DESCRIPTION OF THE DRAWINGS
FIG. 1 shows a foot washing station 100 showing the presently preferred embodiment of the present invention. The foot washing station 100 is composed of a foot platform 102 which accepts the foot, or more preferably feet, of a user as shown in phantom in FIG. 1. The platform 102 is preferably constructed of material such as skid resistant metal or plastic such as diamond plate aluminum, molded plastic with ridges, etc. Starboard formed plastic is shown forming the platform 102 in FIG. 1.
As a user steps on foot platform 102, valve 104 shown in FIGS. 2 and 3 opens as the platform contacts and depresses actuator 106 thereby opening valve 104 allowing the flow of water through valve 104 shown in FIGS. 1 and 2 from a supply 107 such as a pipe, hose, etc., through valve 104 into the manifold 108 as shown in FIG. 2. The manifold 108 distributes water to spray members 110,112 preferably having a plurality of orifices 114. Preferably, at least some of the orifices 114 have spray nozzles 116 placed therethrough. The nozzles 116 receive water which passes through orifices 114 and then sprays this water into the foot washing station 100 preferably at the inserted feet and/or lower legs. Caps or plugs 118 can be useful in other embodiments to plug orifices 114 which are not utilized in conjunction with spray nozzles 116. In some embodiments, orifices 114 having plugs 118 may not be utilized to spray. The nozzles 116 preferably screw into orifices 114.
The nozzles 116 and/or orifices 114 are preferably disposed at a plurality of elevations 120,122,124,126 relative to the feet of a user. Additionally, at least a portion of the spray members 110,112 are non-linear with non-adjacent nozzles 116 and orifices 114 being non-linear relative to non-agreement or agreement nozzles 116 and orifices 114 such as on a curved span. This can be clearly seen from the spray member 112 shown in FIG. 1. The applicant has discovered that these different elevations of non-linear assist in providing a spray which efficiently removes debris and/or other material from the lower leg and feet of a user. By having the nozzles 116 and/or orifices 114 disposed above the feet, a downward spray pattern has also been found to efficiently remove such debris or other material from the feet of a user. Other or additional spray patterns could also be employed.
Nozzles 116 are preferably spray nozzles which distribute water over a specified pattern under desired pressure. The water pressure can be estimated based on known conditions thus allowing optimum selection of nozzles 116. Spray patterns for nozzles 116 are also selectable such as full cone, cone, square cone, etc. It is preferred that nozzles 116 provide small water droplets such as mist to assist in cooling water which may have been heated by sun shining on the spray members 110,112.
As water proceeds from the supply 107 through valve 104 in the manifold 108, in the preferred embodiment it can proceed through support arms 130,132 to spray member 112 and through either or both of conduits 138,140 to the other spray member 110. Manifold 108 can include director pipe 128 as well. Other water flows can be provided from the supply 107 through valve 104 to each of the spray members 110,112 as is known in the art.
As the user steps upon the foot platform 102, the actuator 106 is depressed as springs 142,144 are depressed. At least a portion of the foot platform 102 preferably contacts the actuator 106 sufficient to at least partially open the valve 104. In the preferred embodiment, the platform 102 bottoms out against at least a portion of base 146 after traveling a predetermined distance. This predetermined distance 148 is preferably about the same length of travel as the actuator travel 106 to open the valve 104. It is also preferably a little less than maximum travel of the actuator 106 to prevent excessive wear. A recess could be useful to allow the valve 104 to fit below the foot platform and operate properly with the surface of a recess contacting the actuator 106. The recess could be recessed relative to an interior surface 152 of the platform 102. The exterior surface 154 of the platform 102 is preferably sloped from a peak 156 which may be curved down to its sides 155,157 so to provide a water runoff point for the entire foot platform 102. This is believed to enhance the removal of debris from the feet as it doesn't give the opportunity for debris to puddle up on the foot platform 102 which is believed to be possible with many, if not all, of the prior art designs.
Panels 158,160 are useful to restrain overspray past the opposing panels 158,160 so that someone walking by the side of the foot washing station 100 in operation may not be hit with overspray. The front 162 and back 164 are preferably unobstructed above the foot platform 102 to allow an individual to walk in and out in a relative easy manner. In fact, multiple foot washing stations 110 can be placed in a row and possibly connected together so that a user could walk through it and potentially not stop or stop for a relatively short period of time to adequately remove debris from his or her legs.
When the user removes his/her weight from the foot platform 106, springs 142,144 preferably return the foot platform 102 to the position shown in FIG. 2 thereby allowing the actuator to return to the off position to shut valve 104.
FIG. 1 is useful to show various elevations 166,168,170 as it relates to the feet and legs 172,174 of the user.
Alternatively preferred embodiments of the present invention of a foot washing station with a foot platform could have members 26 with parallel members which have spray holes or nozzles therein. Upwardly extending members could support the parallel members and receive water and are connected together by at least one lower conduit if not two. The valve could be lever activated with a lever and spring members could be useful to support the foot platform so that the lever would not be actuated in a non-in-use position. When a force is applied to the platform the springs could depress allowing the lever to be depressed allowing water to flow from the inlet to the valve and into the various portions of the conduit, upward members and to the spray members. Of course, the upward members could also have holes. The valve is preferably actuated by the force of the persons weight on the foot platform 12.
In this alternately preferred embodiment, instead of forming the foot platform from aluminum, it could be injection molded or vacuum molded or otherwise molded from plastic but still preferably sloped from a top peak down to the sides so that water does not puddle up on the foot platform.
The development of the applicant's invention has been an ongoing process. One advantage of the presently preferred embodiment shown in FIGS. 1-5 is that the spray nozzles and the diameter of the members of the manifold 108 have been selected so that the water pressure provided to the nozzles 106 in sufficient to get the desired spray pattern from the nozzles 106. The placement of the nozzles 106 has also been selected to enhance the spray coverage and removal of debris from the legs in a sufficient manner which is not believed to have been done in the prior art. The parabolic shape of the spray members 110,112 is also believed to be advantageous as is the sloped nature of the foot platform 102. The platform 102 is preferably constructed so that cups 180,182 go at least about a portion of springs 142,144 and contact the base 146 which is illustrated in FIG. 6 as cross-members 184,186. These members are illustrated as angle iron which preferably do not extend downwardly below the bottom surface of conduits 138,140. By having this construction, it is possible that panels 158,160 can have feet 188,190 which contact the surface such as a side walk, grassy area, etc., and support the foot washing station 100 thereabove in a somewhat level manner so that it doesn't rock around when installed.
Numerous alterations of the structure herein disclosed will suggest themselves to those skilled in the art. However, it is to be understood that the present disclosure relates to the preferred embodiment of the invention which is for purposes of illustration only and not to be constructed as a limitation of the invention. All such modifications which do not depart from the spirit of the invention are intended to be included within the scope of the appended claims.
