Abstract
A foot treating apparatus comprising a basin that is adapted for accepting and containing bathing water and is shaped and arranged to accommodate two human feet within the bathing water. A steam generator is included and adapted to accept and contain steamable water, to convert the steamable water into steam, and to direct the steam through a steam vent disposed above the bathing water and at one or both of the soles of those feet when the feet are removed from the bathing water. Dry massage means, heating means, vibration, and aeration are also provided.
Description




BACKGROUND OF THE INVENTION




The present invention is an apparatus for bathing human feet while providing massage, heat, aeration and steam therapy. More particularly, the present invention relates to a portable footbath capable of providing various combinations of massage, heat and aeration for the feet, with the optional feature of selectively applying steam therapy directly to the soles of the feet.




The prior art includes numerous footbaths, which are capable of providing either a vibrating foot massage alone or a vibrating foot massage with supplemental heat and aeration. Numerous such devices additionally provide water jets for directing a water spray at the upper surfaces of the feet. Yet it is the soles of the feet that are found to be most in need of therapeutic treatment, and especially of such treatment including the application of steam. Steam applied to the soles of the feet, especially in combination with the soaking effects of the bath and the effects of massage is found to soften calluses and to help remove dead skin, while invigorating the muscles and live skin of the soles, and while reducing overall foot pain. Of all of the parts of the foot, it is the sole that takes most benefit from therapeutic treatment. For example, the sole contains many of the vital points that are addressed by acupuncture due to their close relationship with various organs. It is well documented that stimulation of these vital points reduces fatigue and revitalizes those organs.




To date, numerous complicated and expensive foot bathing and treating devices have been offered which bathe and massage the feet, but none have provided for the selected combination of bathing, massage, heat, aeration and steam, especially with the optional application of steam directed to the soles.

DESCRIPTION OF THE PREFERRED EMBODIMENTS




The preferred embodiment is now described with reference to

FIGS. 1 through 8

. Footbath


100


includes tub


102


and tub base


104


, which are attached to each other to form a tub housing


106


.




The tub housing


106


comprises an upper rim


108


, which, together with tub shroud


110


define a foot opening


112


through which one places one's feet to insert them into the interior cavity


114


of the tub


102


. Within the tub housing


106


are numerous electric components including a steam generator


120


, a vibrator


122


, an aerator


124


, and a heater


126


.




Preferably hot water


130


is poured into the interior cavity


114


of the tub


102


to fill-line


132


. Once inserted through foot opening


112


and into the water


130


, the soles of one's feet are rested on the bottom surface


134


of the tub's interior cavity


114


, thus raising the operating water level


136


above fill-line


132


.




Dry-massage rollers


140


are disposed on footrest


142


, which one can use to massage the soles by running the soles back and forth there against while applying downward pressure. As well as providing expected comfort to the soles, these rollers are found to have a beneficial effect of loosening dead skin from the soles of soaked feet. Although these rollers are found to be preferable, other dry-massaging means from the art may be substituted therefore, provided that the substituted means are capable of providing stimulation to the soles while working the skin of the soles to loosen dead skin and calluses.




Switch


144


is disposed in the tub shroud


110


, and is electrically connected to the electrical components within the tub housing


106


and to an external power supply (not shown). The switch has four operating positions;“Off”,“Massage & Heat”,“Heat & Aeration”, and“Massage, Heat & Aeration”. In the“Massage & Heat” mode, vibrator


122


and heater


126


are energized. In the“Heat & Aeration” mode, heater


126


and aerator


124


are energized. In the“Massage, Heat & Aeration” mode, vibrator


122


, heater


126


, and aerator


124


are all energized. During any of these three non“Off” positions, the steam generator


120


is energized and prepared to produce steam only if water has been poured thereinto, separate from the water


130


within the tub's interior cavity


114


.




Vibrator


122


includes an eccentrically imbalanced motor


146


that causes the entire tub housing


106


to vibrate when energized. This vibratory action is transmitted directly to the soles of the feet through bottom surface


134


, as well as into the water


130


within the tub's interior cavity


114


, causing a massaging effect to the feet entirely. There are numerous other means and methods for providing such a vibratory action to be found in the art, which may be substituted for the imbalanced motor


146


of the preferred embodiment while remaining within the scope of the invention.




Heater


126


warms bottom surface


134


from within the housing


106


. This heats the soles of the feet directly, and is then conducted into and through the water


130


. This not only heats the water and maintains its warmth, but also warms the feet entirely. Other heating means may be substituted from the art while remaining within the scope of the invention so long as the substitute heating means at least provides heat to the water.




Aerator


124


includes pump


150


and hosing


152


. The pump forces air through the hosing


152


and from orifices


154


in bottom surface


134


where it rises as small bubbles against the soles. Although the preferred embodiment employs such an air pump, it is anticipated that a siphoning water pump could be used to recirculate the water


130


from the interior cavity


114


while siphoning air into the water before returning it to the cavity. Any similar means could be substituted from the art for injecting bubbles into the water.




Steam generator


120


is disposed under footrest


142


and includes a positive temperature coefficient (PTC) heating element


160


housed within a boiling chamber


162


. Water


130


poured into the boiling chamber


162


through fill spout


166


is heated by the PTC element


160


, when the switch


144


is in a non“Off” position, and is thus converted to steam, which rises through footrest


142


to steam vents


168


, disposed just below the dry-massage rollers


140


. By lifting the foot from the water


130


in the interior cavity


114


and placing it over the steam vents


168


, one is able to steam treat the soaked sole while massaging it against the rollers


140


, or simply to enjoy the soothing effect of the steam against the sole without massage. Although the PTC heating element and boiling chamber arrangement described is preferred, other means for generating steam may be substituted from the art without departing from the scope of the invention.




In addition to the heretofore unrealized comforting effect obtained by the present invention's combination of various therapeutic treatments on the soles of the feet, it is found that the combination of steam and dry-massaging on soles after they have been soaked in hot aerated water is particularly effective in removing calluses and dry skin.




While one preferred embodiment of the invention has been described, it will be understood by those skilled in the art that it is by way of example and that various changes and modifications may be made without departing from the spirit and scope of the invention, which is intended to be defined only by the appended claims.
