Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention is directed to bath seats which are utilized to support an individual in a bathtub and more particularly to bath seats which are designed to be compactly folded for portability and storage and which are light weight thereby facilitating handling and use.




2. Brief Description of the Related Art




There are many people who because of age or physical disability require assistance when using a shower or bathtub. often, such individuals must be supported on a seating unit which is provided specifically for use with a bathtub or shower enclosure. Because of this, it often becomes necessary for an aide, nurse or family member to exert a great deal of physical effort to lift and lower an individual into a bathtub or to lift an individual onto a seating unit position within the bathtub or shower. A number of prior art seating devices have been designed to alleviate such physical effort.




Some prior art structures have been designed to be permanently installed adjacent to a bathtub or shower enclosure. Unfortunately, such permanently installed structures are often not practical especially when individuals travel, visit with friends or family or when the size of the bathroom does not permit such permanent installation. Examples of this type of seating unit or support device are disclosed in U.S. Pat. No. 1,076,808 to Arborg, U.S. Pat. No. 2,052,629 to Higgins and U.S. Pat. No. 5,263,207 to Gilbert.




Other bathtub seating units include very basic structures which are designed to include bench-like surfaces for supporting an individual within a bathtub. Unfortunately, such bench-type seats require that an individual either seat themselves on the bench within the bathtub or be lifted and placed on the bench. If an individual does not have the physical ability to seat him or herself, it is generally not practical to use a fixed bench-type seating unit for a bathtub or shower enclosure.




To facilitate the positioning of an individual on a bath chair or seat, some bench-type supports have been designed which include cantilevered portions which extend from the sidewall of the bathtub or enclosure. Such portions provide initial support for an individual being assisted. After an individual is seated on a cantilevered seat, the individual may thereafter be moved so that they are positioned between the sidewalls of the bathtub or shower enclosure. Examples of such bathing support devices are disclosed in U.S. Pat. No. 4,391,006 to Smith, U.S. Pat. No. 4,472,844 to Mace and U.S. Pat. No. 4,520,505 Hatala.




Some seating devices for use with bathtubs have been designed to be more portable in nature. In U.S. Pat. No. 4,359,791 to Thomas, a slidable seat is disclosed which is mounted on a frame having a pair of legs supported by a bathtub and a pair of legs which are engageable with a floor exteriorly of the bathtub. The overall structure, however, is not securely positioned on the bathtub and can be displaced when in use. Additional examples of bathtub seating devices are disclosed in U.S. Pat. No. 4,168,549 to Davies, U.S. Pat. No. 5,373,591 to Myers and U.S. Pat. No. 4,150,445 to Bailey.




An improvement over prior art portable bath seating units is disclosed in U.S. Pat. No. 5,784,728 to Weddendorf et al. The bathing unit disclosed includes a frame which is designed to be mounted to the upper walls of a bathtub or shower enclosure. A carriage is moveably mounted to the frame such that a chair carried by the carriage may be moved from a first position which allows an individual to be seated upon the chair above the outer sidewall of bathtub and, thereafter, the chair pivoted on the carriage and the carriage moved so that the seat is positioned within the bathtub or shower enclosure. The frame is stabilized by a pair of foldable legs which engage a bottom wall of the bathtub and a pair of front clamps which engage over the outer sidewall of the bathtub. Although the seating unit disclosed in this patent exhibits an improvement over prior art portable bath seating units, the use of the carriage for supporting the seat and the support structure for the main frame add both to the cost of the unit as well as the bulk and weight of the unit which in some degree, has an effect on portability and handling of the seating unit.




In view of the foregoing, there remains a need to provide lightweight, sturdy, and portable bath chairs or seats which may be easily and compactly transported and stored when not in use but which may be readily and securely mounted to a bathtub or bathtub enclosure to provide a safe support for an individual requiring the use of a seating device when bathing or showering.




SUMMARY OF THE INVENTION




The present invention is directed to a lightweight portable seating unit for use with a bathtub or shower enclosure which includes a platform having an outer or first end portion which is designed to be seated upon an outer sidewall of a bathtub while an inner or second end is supported by a pivotably leg assembly which is engageable with a bottom wall of the bathtub. The platform is secured to the bathtub by an adjustable clamp assembly including oppositely oriented clamp members which are pivotal from a stored position beneath the platform to a deployed position engageable with opposite surfaces of the outer wall of the bathtub. The pivotable leg assembly is moveable between a first stored position beneath the platform to a deployed position wherein the legs provide support for the inner end of the platform. A lock is provided for retaining the leg assembly in either the stored or deployed position. A carrying handle for the seating unit is pivotably mounted to the platform adjacent the clamp assembly and, when moved from a toting or carrying position to a position beneath the platform, is operative to cam one of the clamp members of the clamp assembly tightly against a side wall of the bathtub.




The invention further includes a seat which is slideably supported on roller bearings on the platform and is guided within a slot formed in the platform. The seat may be rotated at an inner portion of the slot. An individual may be seated on the seat exteriorly of the bathtub, afterwhich, the seat is moved along the platform such that the individual is seated between the sidewalls of the bathtub. Thereafter, the seat is rotated to reorient the seat relative to the platform. The invention may include a locking device to retain the seat in a deployed position when in use so that the seat cannot shift relative to the platform on which it is supported.




In a further embodiment of the present invention, a bidet-like device may be attached to a modified seat to further provide for a thorough cleansing of an individual on the seating unit. The first modified seat includes recesses in a base and backrest into which the bidet device is frictionally fitted.




In some embodiments of the invention, a tray is detachably mounted to the inner end of the platform so as to be situated generally over an inside wall of the bathtub. The tray may include openings for draining water during use.




A further seat modification is provided which is designed to permit varying degrees of patient reclining as well as patient head support. In this embodiment, the seat includes a backrest which is adjustable to vary its tilt angle. When not in use, the backrest is folded against the seat bottom. A head rest is telescopically mounted to the backrest and may include a strap for securely retaining a patient's head to the headrest. To provide additional stability to the seating unit when the modified seat is in use, a bracket is provided which is engageable with the platform and which extends therefrom to engagement with an endwall of a bathtub in the direction of the tilt angle of the backrest.




It is the primary object of the invention to provide a portable bath seat which is extremely lightweight and compact thereby facilitating portability and deployment for use and yet which is sturdy enough to support larger individuals requiring assistance when bathing or showering.




It is also an object of the invention to provide a portable bathing unit which includes a seat which is maneuverable from a first position where an individual may be seated while they are exterior of a bathtub or shower enclosure to a second position wherein the seat is rotatable within the bathtub or shower enclosure.




It is another object of the invention to provide a portable bath seating unit which includes a platform which sideably supports a seat including roller bearings and wherein the platform is supported by legs which are pivoted from a stored position beneath the platform to a deployed position where the legs engage a bottom surface of a bathtub or shower enclosure.




It is another object of the invention to provide a portable seat assist device for use with bathtubs and shower enclosures wherein the seating unit may be adapted to retain a fluid discharge bidet-device for facilitating patient cleansing.




It is a further object of the invention to provide a portable bathing unit which includes structure to permit a patient to be seated at various tilt angles without the unit becoming unstable and wherein a patient's head can be stabilized.




It is also an object of the invention to provide a portable bath seat which can be securely clamped to a bathtub using cam leverage provided by a carrying handle associated therewith.

DESCRIPTION OF THE PREFERRED EMBODIMENT




With continued reference to the drawings, the portable lightweight bathtub seating unit


10


of the present invention is shown as being mounted to an outer side wall


12


of a bathtub


13


. Although the seating unit is shown as being supported by only an outer wall of the bathtub, the seat can be utilized in enclosures where there is a ledge provided on the inside wall


11


of the bathtub.




The seating unit includes a platform


15


which is shown in

FIGS. 1 and 12

as being generally rectangular in configuration having a first end portion


16


adapted to be positioned adjacent the outer wall


12


of the bathtub and a second end portion


17


adapted to be positioned adjacent to but normally spaced from the inner wall


11


of the bathtub. The first end portion


16


is also shown as being cantilevered outwardly beyond the outer wall


12


of the bathtub. The platform is preferable molded from a plastic material which is reinforced by opposite sidewalls


18


and


19


and front and rear wall


20


and


21


, as shown in FIG.


4


. Further reinforcing is provided by a web


22


which extends between the sidewalls


18


and


19


and a pair of longitudinal webs


23


and


24


which extend from the web


22


toward the second end portion


17


of the platform. The rear portion of webs


23


and


24


are connected by a closure panel


25


so as to create an enclosed housing


26


, as shown in

FIGS. 3 and 4

. The first end portion


16


of the platform is further reinforced from the bottom by spaced webs


27


and


28


which also serve as guides for a clamping mechanism to be described in greater detail hereinafter. The webs are connected by opposed walls


29


and


30


which, together with the webs


27


and


28


, form a slide housing.




As shown in

FIGS. 3 and 15

, a tray


31


is removably mounted to the end portion


17


of the platform for purposes of supporting soaps, shampoos, creams, sponges and the like which may be utilized by individuals using the seating device. Holes


32


are provided within the bottom of the tray to provide for necessary drainage. The tray may be attached in any number of ways to the end wall


21


of the platform


15


. As shown in

FIGS. 15-17

, the tray may include studs


31


A which are receivable within slots


31


B formed in the end wall


21


.




The platform


15


also includes an elongated slot


34


therein which extends generally along a longitudinal axis A—A thereof from an enlarged opening


35


spaced intermediate the end portions


16


and


17


to an end


36


spaced adjacent the end portion


16


. The slot defines a guide track for a seat


37


which is slideably mounted on the platform


15


, as will be described in greater detail.




To secure the platform


15


to the sidewalls of a tub, a clamp mechanism or assembly


38


is provided adjacent the housing


36


. The clamping mechanism includes a pair of outer clamp members


39


and


40


which are spaced from one another and which are pivotably mounted about pivot rods


42


and


43


which are secured to the sidewalls


18


and


19


and webs


27


and


28


adjacent to the front wall of the platform


15


. The members may be pivoted from a stored position, as shown in

FIG. 4

, where the members underlie the platform


15


to a deployed position, as shown in

FIGS. 1 and 3

, where the inner surface of each member is engageable with the front surface


12




a


of sidewall


12


of the bathtub. In this position, the sidewalls


18


and


19


and the web walls


27


and


28


rest against an upper wall


12




b


of the bathtub. The clamp members


39


and


40


are pivotable relative to the platform


15


but are otherwise not moveable with respect thereto. As shown in

FIG. 8

, the clamp members are retained in a stored position beneath the platform by friction tabs


27




a


and


28




a


molded to the webs


27


and


28


. In some embodiments only a single outer claim member may be used.




With specific reference to FIGS.


4


and


8


-


11


, to provide an opposing clamping force, a central clamp member


44


is pivoted by stub shafts


45


and


46


to opposing sidewalls


47


and


48


of a generally C-shaped slider


50


. The member includes a rear wall


51


having a threaded opening


53


there through in which an adjustment screw


52


extends. The adjustment screw extends forwardly through openings in housing member


29


and the front wall


20


of the platform. The screw is connected to an operating knob


55


which is used to rotate the screw to move the slides


50


forwardly and rearwardly carrying with it the clamp member


44


. In this manner, the clamp member


44


may be moved relative to or away from the front clamp members


39


and


40


to thereby clamp the platform to the front wall of the bathtub. It should be noted that the clamp member


44


includes a cut-out


56


adjacent to the central portion thereof to provide clearance for the adjustment screw


52


so that the clamp member


44


can pivot from a fully stored position underlying the platform


15


, as shown in

FIG. 4

, to a deployed and vertically depending extended position as shown in

FIGS. 1 and 3

. When the adjustment clamp


44


is in the deploy position, by adjusting the screw


52


utilizing the knob


55


, a clamping action is creating by the central clamp member


44


against the inner surface


12




c


of the tub wall


12


and the outer clamp members


39


and


40


against the inner surface


12




a


. The clamp member


44


is retained in a stored position by friction tabs


276


, see FIG.


8


.




In order to facilitate portability and to also provide a further means for securely clamping the bath seat to the wall of the bathtub, a carrying handle


60


is connected to an elongated cam shaft


61


. The handle includes side portions


62


and


63


which are connected to stub shafts of the cam shaft such that the handle may be pivoted to a downward locking position, as shown in

FIG. 10

, from a deployed position utilized for carrying, as shown in

FIGS. 8 and 14

.




To facilitate the clamping action of the assembly


38


to securely mounted the bath seat to the side wall of the bathtub, the adjustment screw


52


has a collar


65


fixedly secured thereto adjacent to, and engageable by, the cam shaft


61


. The cam shaft includes a protruding curved camming surface


66


which is forced against the collar when the handle is pivoted from the deployed position of

FIG. 8

to a stored position of

FIG. 10

as shown by the arrow in FIG.


9


. As the cam engages the collar, the adjustment screw


52


is to forced toward the front of the platform thus pulling the U-shaped slider


50


and clamp


44


forward to thereby apply locking pressure on opposite sides of the sidewall


12


of the bathtub. Such locking of the clamp member allows a firm pressure to be applied by the clamping member after the knob


55


is used to obtain a close fit between the clamping members and the sidewall


12


. As shown in

FIG. 11

, the slider


50


mounted within the housing


36


is further prevented from lateral movement by providing slots


68


in the web walls


27


and


28


in which guide tabs


69


from the C-shaped slider extend.




To support the inner portion of the bath seat of the present invention, the platform


15


carries a leg assembly including a pair of legs


70


and


71


which are connected at their upper ends


72


and


73


, respectively, by a shaft


74


. The legs are designed to be mounted to the platform adjacent to the rear end thereof so as to be spaced inwardly from the inner sidewall


11


of the bathtub. In this respect, the legs may be utilized to support the bath seat even if there is not a sufficient ledge on the inner wall


11


of the bathtub to provide support for the inner end portion of the platform.




As shown in

FIGS. 3-5

, the shaft


74


of the leg assembly extends through openings


75


and


76


formed in the web walls


23


and


24


of the housing


26


. The legs


70


and


71


may be integrally formed or may be separately molded and connected to the shaft


74


. A pair of openings


77


and


78


are provided through the shaft


74


and generally centrally thereof and at 90° with respect to one another for purposes of receiving a locking pin


80


which extends through a flange


81


defining a front wall of the housing


26


. The handle


60


includes an inner stop


82


which is engaged by a spring


83


mounted within the housing


26


which normally forces the handle to a closed or locked position, as shown in

FIG. 3

, where the locking pin prohibits rotation of the shaft


74


. In

FIG. 3

, the legs


70


and


71


are shown as pivoted to support the bath seat relative to a bottom wall “B” of the bathtub. To adjust for the depth of the bottom wall, each of the legs


70


and


71


includes a threaded extension


85


having a footpad


86


to prevent marring of the tub surface. When it is desired to collapse the legs relative to the platform, the locking pin


80


is pulled outwardly against the spring


83


and, thereafter, the legs pivoted into underlying relationship with respect to the platform such that the pin aligns with the opening


79


in the shaft


74


so that the pin, when released, engages within the opening


79


to thereby lock the legs in a stored or collapsed position, as shown in

FIG. 4

of the drawings.




As previously discussed, the present invention incorporates a seat


37


which is slidably mounted on the upper surface of the platform


15


. The seat includes a base


90


having a plurality of fluid draining opens


91


therein. The base may have a flat upper surface or contoured upper surface with the contoured surface being shown in the drawing figures. The base is integrally formed with a small backrest portion


92


. Handles


93


are provided at opposite ends of the base which may utilized to manipulate the seat and also to provide support for an individual situated on the seat. Holes in the backrest may be used for supporting an extended backrest.




As shown in the drawings, the seat is designed to rotate relative to the platform. In this respect, in

FIG. 1

, the seat is shown as being at an outermost position wherein the seat is generally above and slightly cantilevered outwardly from the outer sidewall


12


of the bathtub. In this position, the seat may not be rotated relative to the platform and the seat is oriented to facilitate a person being seated. Once seated, the seat is designed to be urged to the center of the platform where the seat may be rotated


90


degrees to the position shown in FIG.


2


.




With particular reference to

FIG. 12

, the underside of the seat bottom is reinforced by a plurality of longitudinally and transversely ribs


94


and


95


. Adjacent the center of the seat bottom are two studs


96


having openings for receiving appropriate fasteners. A seat retainer slide block


100


is provided on the bottom side of the platform


15


and includes an enlarged head or flange


101


of a size to prevent the block from passing through the opening


35


and slot


34


in the platform. An oblong stem


102


extends upwardly from the head so as to pass through the slot


34


and the opening


35


in the platform. A pair of openings


103


are provided in alignment with openings in the studs


96


in the base of the seat so that fasteners, such as screws, may be utilized to secure the block to the studs thereby mounting the seat to the platform. Because of the oblong configuration of the stem


102


, when the block is positioned in the opening


35


in the platform, the seat may be rotated freely. However, when the seat is to be moved outwardly along the platform, the seat is rotated so that the oblong stem fits within the slot


34


thereby allowing the seat to be moved only longitudinally relative to the axis A—A of the platform. The oblong stem


102


will prevent rotation of the seat while deployed within the slot


34


thus insuring stability of the seat during use.




The seat


37


is supported on a plurality of plastic ball bearings


110


which are mounted within sockets


112


which are molded between the reinforcing flanges


94


and


95


in the bottom of the seat. Although


12


roller bearings are shown for supporting the seat in drawing

FIG. 12

, the number and their disposition may be varied.




The seat may also incorporate a friction brake which retains the seat in an adjusted position relative to the platform


15


, see FIG.


18


. The brake is shown generally at


114


and includes a pair of handles


115


mounted on opposite sides of the seat base which are mounted to the ends of a pivot rod


116


which extends through openings through the sides of the seat base. The central portion of the rod


116


is generally U-shaped at


117


and extends through a plastic block


118


to which is secured a rubber friction brake pad


119


which is engageable with the upper surface of the platform. The brake is normally applied under the influence of a spring


120


which extends to the base of the seat. The spring normally urges a central portion of the U-shaped element downwardly so as to apply the brake against the upper surface of the platform. To release the brake, the handles are pivoted upwardly thereby pivoting the brake rod


116


upwardly against the spring and raising the plastic block which supports the brake pad. Upon release of the handles


115


, the brake is automatically applied to prevent further shifting of the seat relative to the base.




To the reference to

FIGS. 19-21

, a different embodiment of seat is disclosed for use with the platform


15


of the present invention. In this embodiment, the seat is designed specifically for use for individuals who must have positive back and head support when utilizing the bath seat. The structure of the platform


15


, the clamping mechanisms and the support legs are identical to the previous embodiment. The modified seat


125


includes a base


126


which is mounted on roller bearings as previously discussed. Also, as with the previous embodiment, a break mechanisms controlled by a handle


115


may also be provided for securing the seat in an adjusted position, as shown in FIG.


19


. The seat


125


includes a backrest


128


defined by a frame having side members


129


and


130


each of which are pivotally mounted at the rear of the base


126


. The side members


129


and


130


are reinforced and supported by foldable struts


131


and


132


each of which are pivoted at their central portion


133


and


134


, respectfully. A pivot stop


135


is provided at each pivot joint


133


and


134


for purposes of limiting the pivotal movement between the two components of each strut assembly. As shown, the strut assembly may be folded so that the backrest


128


will overlay the base


126


in a generally parallel relationship therewith when in a stored position but may be readily extended when the backrest


128


is pivoted to the raised position, as shown in FIG.


19


. The backrest further includes an upper horizontal support member


138


which is integrally formed with the side members


129


and


130


and which includes a general central slot


140


therein. A headrest


142


is slidably inserted within the slot


140


and is stabilized at its lower end by a cross brace


144


which extends between the side members


129


and


130


. The headrest


142


is designed to be elevated relative to the backrest to a proper position so that an individual's head may be supported thereby. The headrest is locked in place by thread lock


143


. Thereafter, an individual's head is secured thereto by straps


145


and


146


. The straps may include cooperating hoop and loop fabric material fasteners, such as Velcro™, for purposes of securing the straps tightly about an individual's forehead and thereby provide lateral stability for the head and neck when using the bath seat.




The present embodiment is also design for a patient to be reclined. In this respect, and is shown in

FIG. 20

, each of the vertical members


129


and


130


includes a plurality of openings therethrough as shown generally at


150


and


152


. Any number of spaced openings may be provided for purposes allowing adjustment of the backrest, as shown in dotted lines in FIG.


20


. Each strut assembly includes an opening in the upper end thereof through which a locking pin


154


is selectively inserted in order to retain the backrest


128


at a desired angle of inclination.




To provide additional lateral support for the bath seat of the embodiment shown in

FIGS. 19 and 20

, the present embodiment includes a supplemental support bracket


160


, as shown in FIG.


21


. The bracket includes a pair of opposing clamp elements


161


and


162


which are designed to be slidingly engaged over the inner end portion


17


of the platform


15
