  • Open end 40 has a plurality of L-shaped key slots 44 spaced approximately equal to the spacing of tabs 38 on lock plate 22 .
  • Impeller housing 24 is coupled to lock plate 22 by sliding impeller housing 24 over lock plate 22 , fitting tabs 38 into the vertical portions of key slots 44 .
  • Impeller housing 24 is then rotated slightly, sliding tabs 38 into the horizontal portions of key slots 44 , substantially trapping tabs 38 in key slots 44 and compressing lock plate 22 between impeller housing 24 and basin 12 .
  • the closed end 42 of the impeller housing 24 has a plurality of upper key slots 43 spaced approximately equal to the spacing of upper tabs 45 on the enclosure 20 .
  • the closed end 42 is coupled to the enclosure 20 by fitting upper tabs 45 into the upper key slots 43 and rotating slightly the closed end 42 substantially trapping the upper tabs 45 in the upper key slots 43 .
  • Impeller housing 24 also includes one or more orifices 49 about the periphery of impeller housing 24 proximate open end 40 .
  • Orifices 49 are openings (e.g., apertures, holes, outlets etc.) that allow fluid to be expelled from the enclosure 20 by impeller 14 .
  • Impeller housing 24 also includes one or more arcuate slots 47 evenly spaced about the periphery of impeller housing 24 proximate closed end 42 .
  • Arcuate slots 47 are openings (e.g., apertures, holes, inlets etc.) that allow fluid to be drawn into enclosure 20 by impeller 14 .
  • Impeller housing 24 may be composed of various materials including plastic, metal, or some combination of plastic and metal.
  • Impeller 14 includes a multitude of blades 50 that extend outward from a central portion with a keyed opening 52 that engages keyed shaft 23 of upper impeller shaft. As impeller 14 rotates, blades 50 directs fluid out of orifices 49 .
  • a baffle disk 54 is coupled to the enclosure 20 .
  • Baffle disk 54 is an annular body with an outer edge and an inner edge where outer edge is higher than inner edge. The profile of baffle disk 54 between outer edge and inner edge may be generally linear or may be concave. The inner edge defines a central opening 60 through which a fluid may flow.
  • baffle disk 54 is integrally formed with impeller 14 . According to other exemplary embodiments, baffle disk 54 may be formed separately and mechanically coupled to the enclosure 20 .
  • Enclosure 20 defines an upper region 27 and a lower region 29 .

  • Upper region 27 and lower region 29 of enclosure 20 are separated by baffle disk 54 .
  • the circular opening 60 in the baffle disk 54 provides fluid communication between upper region 27 and lower region 29 of enclosure 20 and provides a funneling effect of the fluid from upper region 27 to lower region 29 . This provides enhanced flow from impeller 14 to orifices 49 in the impeller housing 24 .
  • the fluid pressure may be raised or lowered by changing the shape or number of either orifices 49 or arcuate slots 47 .
  • Orifices 49 are aligned with depressed regions or channels 62 and 66 (e.g., canals, slots, passages) provided in basin 12 .
  • channels 62 and 66 are open passages having a curved radius at an end portion, such that the fluid that exits orifices 49 is directed along the channel and then upward at the terminal end of the channel.
  • orifices 49 are offset from the centerlines of the corresponding channels 62 and 66 by an angle of approximately 6 degrees, as shown in FIG. 2 . The offset compensates for the force applied to the fluid exiting orifices 49 by impeller 14 that causes the stream to be angled slightly, urging the fluid flow into the channel.
  • the spa 10 includes two front channels 62 and two rear channels 66 .
  • the front channels 62 are configured to direct fluid flow towards the ball of the user's feet.
  • the rear channels 66 are configured to direct fluid flow towards the heels of the user's feet.
  • the open channels 62 and 66 provide an easy way to clean the surfaces of the channels 62 and 66 .
  • the fluid it is also possible for the fluid to be directed from orifices 49 to closed tubes in other configurations.
  • Channels 62 and 66 extend below foot region 15 of the basin 12 such that a user places his or her feet in the foot region 15 above the channels 62 and 66 . The fluid is then directed upwardly under a user feet providing a cleaning and massaging action.
  • a contour bulge 64 is disposed and aligned between the front channel 62 and the rear channel 66 .
  • the contour bulge is configured to contact and support the arch of a foot of a user of the pedicure spa 10 .
  • a user would place one foot on one side of the enclosure 20 and one foot on the other side of the enclosure 20 .
  • the arch of each foot would contact the contour bulge 64 thereby positioning each foot to align with the front channel 62 and the rear channel 66 as explained above.
  • the contour bulge 64 can be integrally molded in the lower portion 16 of the basin 12 .
  • the contour bulge 64 can be a separate member and mechanically coupled to the lower portion 16 of the basin 12 with suitable fasteners or suitable adhesives.
  • the contour bulge 64 may be provided with a plurality of protuberances 65 coupled to a surface of the contour bulge 64 .

  • Another embodiment provides the protuberances mechanically coupled to the contour bulge 64 with suitable fastener or suitable adhesives.
  • the protuberance 65 may be of any size, shape and number. The figures illustrate an exemplary embodiment of a contour bulge 64 including six, round protuberances 65 .
  • Impeller housing 24 includes an outwardly extending finger 70 that houses a magnet 72 .
  • Magnet 72 is held within finger 70 by a retaining plate 74 .
  • plate 74 is ultra-sonically welded to the underside of finger 70 . Other methods of welding such as vibration weld, chemical weld, heat stake weld, or the like, can also be performed.
  • plate 74 may be otherwise coupled to finger 70 .
  • magnet 72 interfaces with a switch (not shown) coupled to the underside of basin 12 and allows motor 17 to operate and to turn impeller 14 . If impeller housing 24 is removed, magnet 72 is moved away from the switch, disengaging the switch and preventing motor 17 from activating. In this way, magnet 72 provides an interlock measure that allows impeller 14 to turn only if impeller housing 24 is locked in place.
  • the term “coupled” means the joining of two components (electrical or mechanical) directly or indirectly to one another. Such joining may be stationary in nature or movable in nature. Such joining may be achieved with the two components (electrical or mechanical) and any additional intermediate members being integrally defined as a single unitary body with one another or with the two components or the two components and any additional member being attached to one another. Such joining may be permanent in nature or alternatively may be removable or releasable in nature.
  • Impeller as used herein covers both an impeller and propeller. Further, elements shown as integrally formed may be constructed of multiple parts or elements shown as multiple parts may be integrally formed, the operation of the assemblies may be reversed or otherwise varied, the length or width of the structures and/or members or connectors or other elements of the system may be varied, the nature or number of adjustment or attachment positions provided between the elements may be varied.
