Abstract:
A pedicure spa station platform that includes a raised platform having a front and a rear, and a seat area on the top surface of the platform for attaching a seat or chair. The platform has a basin tray for holding a basin. The basin tray area is positioned in front of the seat mount location. A well entrance is located between the seat area and the basin tray. The well has a sidewall with a front portion and a back portion, and a drain positioned in the sidewall. The sidewall forms a rim near the front portion (the well entrance). A vertical riser is positioned in front of the basin tray, and the vertical riser terminates in a footrest, where the footrest extends in part over and above the basin tray. The foot rest is movable with respect to the raised platform.

Description:
BACKGROUND OF THE INVENTION 
       [0001]    A pedicure spa station is a chair where a user rests and provides the needed equipment for a pedicurist—a basin (also referred to as a “spa basin”) for water and additives, where the user may soak his/her feet, and a foot support where the user can rest his/her feet for access by the pedicurist. After one user has completed a pedicure, the spa basin should be emptied and cleaned for use by the next user. In general, either the spa basin has a drain in the bottom to allow drainage of the basin, or if lacking a drain, the spa basin must be moved to a discharge location remote from the spa station. 
         [0002]    The first option is not optimal, as an integrated spa basin drain, after the spa is drained and cleaned, may hold skin shavings, nail shavings or other biological materials, and hence contaminate the basin and present a sanitary hazard for the next user. The second option, while more sanitary, requires the pedicurist to pick up the water filled basin and discharge it remotely. This causes physical stress on the pedicurist, and presents spill and contamination hazards.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0019]      FIG. 1  shows a spa station comprising a chair or seat  1  positioned on a raised platform  2 . Raised platform means that the top surface (the mounting surface, in general) of the platform is not completely at ground level, that the platform has at least a portion raised above the ground level, such as by a sidewall or legs. For reference, the front  200  of the station refers to that portion of the station closest to the footrest  6 A and  6 B ( FIG. 1 ), while the rear  300  of the station refers to that portion of the station opposite the front  200 . Reference to front and rear of other components of the station (such as the basin, drain well, etc.) are similarly defined. The platform has a basin tray  3 B, an area in front of the chair  1  that is designed to accommodate and hold a spa basin  3 . The basin tray area  3 B may be shaped to mimic the shape of the spa basin  3  (e.g., bowl shaped), or be a flat area, such as shown in  FIG. 5  and  FIG. 6 . The spa basin  3  is separate or separatable from the platform  2 , that is, the spa basin  3  is not integrally formed in the platform and preferably can be removed from the platform. The basin  3  is bowl shaped to retain fluids, and preferably has no drain or other port. A liner may be used in the basin for sanitary purposes. 
         [0020]    The spa station may include a resistance coil or other heater positioned underneath or embedded in the basin tray  3 B, or in a separate plate, such as in a heating pad in the tray area  3 B, to provide additional heating therapy for a user&#39;s feet, as shown in  FIG. 7 . Also, a vibratory plate may be positioned in the tray area  3 B for additional therapy. 
         [0021]    Positioned in front of the basin  3  is foot support member  4 . As shown, foot support member  4  has a vertical riser  6  formed in an arch shape. At the top of the arch is a laterally extending footrest  6 A and  6 B ( FIG. 1 ), one on either side of the arch shaped vertical riser  6 , to accommodate a left and right foot. The arch shape allows the footrest area  6 A and  6 B ( FIG. 1 ) to be positioned in the front of and extending over a portion of the spa basin  3 , as can be seen in  FIG. 2 . This allows for the natural position of a user&#39;s feet with respect to the chair  1 , and provides a working area for the pedicurist. 
         [0022]    As shown in  FIGS. 3 and 4 , the foot support member  4  is hingedly connected to the platform by hinge  60 , thereby allowing the foot support member  4  to rotate forwardly so that the foot support area  4  can be moved out of the path of the spa basin  3  when emptying the basin (later described), as best seen in  FIG. 5  and  FIG. 6 . The spa station also has a latch member  70  to lock the vertical riser  6  to the platform  2 . If the spa station does not have a foot support or foot rests (not preferred), the integrated drain may be located in front of the basin. 
         [0023]    As shown, the vertical riser  6  is hingedly connected to the platform  2 . Another embodiment would have the footrest area hingedly connected to the vertical riser  6 , or have the vertical riser  6  formed from a top section and a bottom section, where the two sections are hingedly joined. Additionally, instead of a hinged vertical joint, the vertical riser  6  may pivot horizontally with respect to the platform  2 , allowing the riser  6  to rotate in a horizontal plane and out of the path of the basin  3  when discharging the basin&#39;s contents. Instead of a hinged or rotative attachment, the footrest may be in a telescoping relationship with the vertical riser, allowing the footrest to telescope out of the way of the path of the basin during discharge. 
         [0024]    Alternatively, the footrest or vertical riser may simply be detachable, or in some embodiments, lacking. 
         [0025]    Positioned in front of the chair  1  and behind the spa basin tray  3 B is a drain area  90 . If the spa station is formed from molded plastic materials, the drain area  90  may be integral to the base  2 . The drain area is formed by a sidewall  91  that creates a well with a well bottom, and has a drain  100  located in the well bottom. Preferably, the well is deep enough to accommodate a sufficient amount of water to prevent overflowing of the drain area  90  when discharging the contents of the spa basin  3 . The drain area  90  (also referred to as a well) is preferably large enough to allow a user to access the well to clean the drain to remove any materials that may impede flow through the drain  100 . The drain connects to plumbing underneath the platform area that supports the chair, which plumbing can be connected to a suitable discharge site. 
         [0026]    The drain sidewall  91  extends upwardly and forms a rim  92  in the front of the well (that is adjacent the basin  3  and slightly below the lip  3 A of the spa basin  3  when the spa basin is resting on the basin tray  3 C). The rim  92  may be shaped in a region adjacent the spa basin  3  to accommodate the lip or edge  3 B of the spa basin  3  in order to support the spa basin  3  when emptying the basin, such as shown in  FIGS. 2 ,  5  and  6 . As shown, the basin  3  has a lip  3 A that extends outwardly from the bowl shape of the basin  3 . Also as shown in  FIG. 6A , the basin has an orientation, that is, the basin is shaped so that one portion is designed or intended to be positioned adjacent the well  90 . In the basin embodiment of  FIG. 6A , the “rear” of the basin is that portion that contains a flat area  85  designed to rest adjacent the sidewall of the well. In this event, the lip or edge  3 A of the bowl only near the drain is of concern. If the bowl has no orientation, that portion of the edge of the bowl that is shaped to cooperate with the rim  92  of the drain will create a bowl orientation, or if the entire surrounding basin edge is similarly formed, the basin has no orientation with respect to the drain. Below the lip  3 A is a flat area  3 C on the bowl. The rim  92  of the drain adjacent the bowl  3  has a similar flat  93 , and the rim&#39;s thickness is sufficient to allow the lip  3 A of the basin to extend beyond the sidewall  91  of the drain during discharge. The details of the rim and lip are more clearly shown in the detail of  FIG. 6A . The rim  92  as described is located as a portion of the front edge of the sidewall  91  forming the well, and the lip  3 A, as described, is located on the rear of the spa basin  3  when positioned on the basin tray  3 B. As such, if the lip  3 A continues around the bowl, or the rim  92  continues around the well, the shapes of these features remote from the area of contact between the rim and lip during discharge do not have to be any particular shape. 
         [0027]    In another embodiment, a hinged basin support may be attached to the platform to support the bowl during a discharge, or be formed in the platform. For instance, a single hinged “L” shaped bracket, where the bottom of the “L” is an annular ring, may be used, with the top of the “L” hingedly attached to the sidewall of the drain area  91  (such as centered on the discharge site). The annular ring may be sized to allow the basin  3  to rest inside the annulus (such as underneath the lip  3 A of the basin, if the basin has a protruding lip), or be sized smaller then the bottom of the basin, to support the basin  3  on the bowl bottom of the basin. Instead of the bottom of the “L” forming an annular ring, the bottom of the “L” may simply form a ledge on which the basin bottom rests. If this type of hinged basin support is utilized, the rim shape  92  and lip  3 B of the bowl do not need to be formed for cooperative support, as the hinge supports the basin. Instead of a single hinged arm, a double hinged arm could be employed, with each arm rotatively connects to the sidewall of the well or other suitable location, and each arm connects to the bottom basin support—such as an annular ring, or plate, or other basin support. Another embodiment of a hinged basin support is shown in  FIG. 9A and 9B . As shown, the rim  92  of the drain area  91  may be shaped to cooperate with the shape of the basin lip  3 A to rotatively (e.g., hingedly) support a basin  3  during a discharge event. Alternatively, a drain bracket  300 , shaped for hingedly supporting the basin, may be attached to the platform to provide a suitable rotating support for the basin  3 . As shown, the drain bracket  300  is attached to the drain area  91 , with top of the bracket  300  forming an open cylindrically shaped barrel area. 
         [0028]    The basin lip  3 A may be formed to rotate on drain bracket  300  (or on formed rim  92 ). As shown in  FIG. 10A and 10B , a hinge pin is not needed to join the two cooperating areas together (e.g., rim and bowl), but a pin or other connector could be used if a more fixed relationship was desired. 
         [0029]    As shown in  FIG. 10A and 10B , in a discharge movement, the lip  3 A and basin rim  92  are shaped (or have a separate bracket) to cooperate together to rotatively support the basin during discharge into drain  91 . As can be seen, the lip  3 A of the bowl is a “U” shaped region  401 , and rests on the open barrel shaped area  301  on the basin rim  92 . The open edge  301  of the barrel shaped area accommodates the edge of the “U” shaped lip  3 A during discharge (as best seen in the detail of  FIG. 10B ). 
         [0030]    Another embodiment of a hinged basin support is shown in  FIG. 11A and 11B . In this embodiment, a basin bracket  400  is attached to the basin  3 , adjacent the discharge side of the basin (basin bracket  400  can best be seen in  FIG. 12 ). As shown in  FIG. 11B , the basin bracket  400  is positioned underneath the lip  3 A of the basin  3 . The basin bracket  400  is shaped to cooperate with either the rim  92  of the drain  91  sidewall, or as shown, on a separate drain bracket  300  positioned on the drain rim  92 , to hingedly support the basin during a discharge event (e.g., when the bowl is rotated upwardly and rearwardly to discharge into the drain on the platform). 
         [0031]    As described, the basin edge and rim of the well may cooperate to form a supporting hinged area for the basin to discharge into the well. Also as described, a separate hinge or rotation support may be provided to allow the basin to discharge into the well, where the edge or lip of the bowl and rim of the well do not cooperate, thus allowing for bowl variations. 
         [0032]    In use, the spa basin  3  is filled with water and additives. After use by a user, the spa basin  3  is emptied by rotating the spa basin  3  upwardly and rearwardly, adjacent the drain sidewall  91 . In the embodiment shown in  FIGS. 5 and 6 , the lip  3 A of the basin  3  extends over the rim  92  of the drain sidewall  91 . The contents of the spa basin  3  will empty into the drain area  90 , and the waters are drained though pipes connected to the drain  100  to a suitable discharge location for disposal. Rotation of the basin  3  continues until the basin  3  is empty. If the hinged basin support is present, this action entails rotating the spa basin  3  about the hinged basin support hinge. The hinged basin support guides and helps supports the filled basin, allowing draining of the basin with little physical effort. An axially-coiled spring may be incorporated in the hinged basin support for enhanced lift assist. 
         [0033]    If the basin support member is absent, then preferably the rim of the drain sidewall and the lip  3 A of the basin  3  are shaped to accommodate one another so that the spa basin is rotated toward the drain area, the rim of the drain area will support and help guide the rotating spa basin. Additionally, the spa basin may have a vertical flat area  3 C that faces the drain sidewall  91  to support the spa basin  3  when discharging the contents of the basin  3  into the drain well. 
         [0034]    As described, the drain  100  is located adjacent the basin and built into the chair support. The spa station is designed to allow a pedicurist to discharge the contents of the spa basin with little effort, and maintain a more sanitary environment for a user. The integrated nature of the well and the cooperating hinged basin support helps prevent the discharged contents from spilling back into the basin.
