Various embodiments of the invention relate to a seat mounted on wheels for rolling along wheel tracks of parallel longitudinal members of a frame having end members connecting the longitudinal members. The frame may be placed on an upper surface of a bath enclosure such as a bathtub or shower unit and turnbuckles in the longitudinal members may be used to friction fit the longitudinal members to vertical surfaces at the end of the bathtub or shower unit. Moreover, the seat may have a bottom portion hingedly attached to a seat back portion so that the seat can be stowed at one end of the bath enclosure by folding the bottom portion towards the back portion.

What is claimed is: 1. An apparatus comprising: a seat mounted on a plurality of wheels; a frame having a pair of longitudinal members each defining a wheel track, the longitudinal members retained in substantially parallel relation by a first and second end members, the frame to be disposed on an upper surface of a bath enclosure; and a pair of turnbuckles to couple the longitudinal members to the first end member to provide longitudinal adjustment of the frame. 2. The apparatus of claim 1 wherein the longitudinal adjustment permits the frame to form a friction fit with a bath enclosure having a length in the range of 53 inches and 73 inches in length. 3. An apparatus comprising: a seat mounted on a plurality of wheels; a frame having a pair of longitudinal members each defining a wheel track, the longitudinal members retained in substantially parallel relation by a first and second end members coupled between the pair of longitudinal members, the longitudinal members having ends to be disposed on an upper surface of a bath enclosure, such that the longitudinal members follow a long dimension of the bath enclosure and having sufficient structural stability to support a 200 pound load in the seat; wherein each longitudinal member includes a first member detachably coupled to a second member by a first pair of rods extending longitudinally through the first and second members, and the second member detachably coupled to a third member by a first pair of rods extending longitudinally through the first and second members, to allow the first and third members to be separated from the second member such that when detached, the first member, second member, and the third member each have a length less than a half length of the longitudinal member. 4. The apparatus of claim 3 wherein less than 15 percent of the longitudinal members are to be disposed on the upper surface of a bath enclosure. 5. The apparatus of claim 3 wherein each longitudinal member includes a first extender detachably coupled between the first and the second member, and a second extender the detachably coupled between the second and the third member. 6. An apparatus comprising: a seat mounted on a plurality of wheels and having a pair of stowable arm rests, a back portion, and a seat portion hingedly coupled to the back portion and moveable between a use position and a stowed position, wherein the arm rests include an arm platform coupled proximate to the back portion; and a support member hingedly coupled to the arm platform distal to the back portion to engage a horizontal surface to reduce tipping when pressure is applied to the arm platform; and a frame having a pair of longitudinal members each defining a wheel track in which a subset of the wheels resides during use, the longitudinal members retained in substantially parallel relation by a first and second end members, the frame to be disposed on an upper surface of a bath enclosure. 7. An apparatus comprising: a seat mounted on a plurality of wheels; a frame having a pair of longitudinal members each defining a wheel track in which a subset of the wheels resides during use, the longitudinal members retained in substantially parallel relation by a first and second end members, the frame to be disposed on an upper surface of a bath enclosure, wherein the seat comprises: a back portion; a seat portion hingedly coupled to the back portion and moveable between a use position and a stowed position; and a hook member extending from the second end member to engage the seat when in the showed position. 8. The apparatus of claim 7, wherein the plurality of wheels comprises a front pair of wheels and a rear pair of wheels and wherein the longitudinal members define a slot in an upper wall the slot overlying the front pair of wheels when the seat is at an extreme of its range of motion along the wheel tracks. 9. The apparatus of claim 7 wherein the seat comprises; a pair of stowable arm rests. 10. The apparatus of claim 7 further comprising: a braking mechanism to restrict motion of the seat along the wheel tracks. 11. An apparatus comprising: a seat mounted on a plurality of wheels; a pair of longitudinal members each defining a wheel track, a first and second end member coupled between respective ends of the pair of longitudinal members, the end members to be pressure fit to vertical surfaces of a bath enclosure. 12. The apparatus of claim 11 wherein each longitudinal member includes a first member detachably coupled to a second member to allow the first member to be separated from the second member such that when detached, the first member and the second member each have a length less than a length of the longitudinal member. 13. The apparatus of claim 11 wherein the first and second end members telescope to provide lateral adjustment of the frame. 14. The apparatus of claim 11 wherein the longitudinal members are to be retained in substantially parallel relation by the first and second end member. 15. The apparatus of claim 14 wherein the first and second end members telescope to provide lateral adjustment of the frame to have a length in a range of 24 inches and 34 inches in length.
