BACKGROUND




The invention relates to child bath seats, such as are used for bathing children.




Children are often placed in a bath seat for support during bathing in a bathtub. Often the bathtub is filled with about an inch of water and the adult uses a sponge or a face cloth to bathe the child while the child sits secured in the child bath seat. Concerns have been raised about the safety of child bath seats, particularly when parents improperly leave the child alone in the bathtub. Improvements are sought in the safety and convenience of bath seats in general.




SUMMARY




In one aspect, the invention features a child bath seat, placed within and attached to a bathtub. The child bath seat includes a seat body that includes both a seat and a retaining structure extending above the seat for laterally retaining a child seated in the seat body. The seat also includes a bracing structure that holds the seat body in an upright position. The bracing structure has a first end attached to the seat body, and a second end, defining a recess, for receiving an upper edge of a side of the bathtub.




Various embodiments have one or more of the following features. For example, the child bath seat may include a clamping mechanism that secures the second end of the bracing structure to the side of the bathtub. Also, the bracing structure may include a horizontal adjustment bracket that allows adjustment of the bracing structure, which corresponds to a width of the side of the bathtub. In addition, the bracing structure may include a vertical adjustment bracket to adjust a vertical position of the seat relative to a bottom surface of the bathtub.




Other embodiments feature a bath seat including a support member attached to a bottom surface of the seat. The bath seat may engage the bottom surface of the bathtub only on a side of the bath seat opposite the bracing structure.




In still other features, the child bath seat, in its upright position and resting on a bottom surface of the bathtub, contacts the bottom surface of the bathtub only on one side of a center gravity of the seat body. Further, the seat body may rest on the bottom surface of the bathtub. Alternatively, the seat body may be suspended over the bottom surface of the bathtub.




In another aspect the invention features a child bath seat placed within and clamped to a bathtub. The child bath seat includes a seat body that includes both a seat and a retaining structure above the seat for laterally retaining a child in the seat body. The child bath seat also includes a bracing structure that holds the seat in an upright position. The bracing structure has a first end attached to the seat body, and a second end that has a clamp secured over an upper edge of the bathtub.




Various embodiments of this aspect have one or more of the features described above.




In another aspect, the invention features a method of securing a bath seat within a bathtub for bathing a child therein. The method includes placing the bath seat into the bathtub. The bath seat includes a seat that includes both a seat and retaining structure extending above the seat for laterally retaining a child in the seat body, and a bracing structure that has a first end attached to the seat body, and a second end defining a recess. The method also includes attaching the second end of the bracing structure over an upper edge of a side of the tub, with the upper edge of the side of the tub received in said recess and the seat body in an upright position.




Various embodiments have one or more of the following features. For example, a horizontal adjustment bracket may be adjusted on the bracing structure to correspond to a width of the side of the bathtub. In addition, a vertical position of the seat may be adjusted relative to a bottom surface of the bathtub.

from tipping bath seat


10


over during bathing or during the child's movements.




Referring to

FIG. 1B

, bracing structure


22


is molded at a proximal end


30


to a side


34


of seat body


26


. A distal end


36


of bracing structure


22


is shaped to correspond to the shape of rim


14


. Distal end


36


forms a gap, G, that accommodates the width of rim


14


so that when distal end


36


of bracing structure


22


is placed over the rim, the distal end wraps around the rim providing a snug fit between the bracing structure and the rim.




Seat body


26


includes a retaining barrier


38


and a seat


42


, which is attached to the bottom surfaces


46


of retaining barrier


38


, e.g., snapped or screwed together. Retaining barrier


38


includes a front restraint


50


and a back restraint


54


is attached using molded snaps (not shown) to front restraint


50


. Front restraint


50


includes a smooth top surface


58


so that child


6


can rest their arms during bathing. Together seat


42


, front restraint


50


and back restraint


54


form a cavity


62


in which child


6


is placed for bathing. In addition, front restraint


50


and seat


42


form two apertures


64




a


and


64




b


, each wide enough so that a leg of child


6


may pass through the aperture. Each component of bath seat


10


is fabricated from injection-molded plastic.




During typically bathing activity, an adult places distal end


36


of bracing structure


22


over rim


14


of bathtub


18


. The adult guides the child through cavity


62


while simultaneously putting the child's legs through apertures


64




a


and


64




b.






In this embodiment, a portion of the seat rests on the bottom surface of the bathtub. In other embodiments, however, the installed seat is suspended over the bottom of the bathtub.




Referring to

FIGS. 2A and 2B

, a second example of a bracing bath seat


100


includes an adjustable bracing structure


102


for bracing with non-standard width bathtub rims and for adjusting a height, H, of the bath seat relative to the bottom of the bathtub. Child bath seat


100


includes adjustable bracing structure


102


and a seat body


106


. Seat body


106


includes a cavity


110


to receive child


6


and two openings


114




a


and


114




b


, each for receiving a leg of child


6


. Seat body


106


also includes two flanges


120




a


and


120




b


located on opposite sides of seat body


106


. Seat body


106


includes a toy rattle


122


for entertaining and distracting the child during bathing.




Adjustable bracing structure


102


includes a clamp housing


124


defining a channel


128


and a recess


130


; a shuttle


132


having a dowel


136


and a slot


140


; an inner pad


144


; and a clamp plate


148


having an outer pad


152


and an aperture


156


. Adjustable bracing structure


102


also includes adjustment screw threads (not shown) for receiving an adjustment screw


160


having a handle


162


. Bath seat


110


is installed by placing dowel


136


of shuttle


132


into channel


128


. As will be discussed below, the location where dowel


136


is placed along channel


128


determines a height, H, of bath seat


100


relative to a bottom


168


of the bathtub. Dowel


132


includes locking screw threads (not shown) for receiving a locking screw


164


. Locking screw


164


is inserted through channel


128


and is received by the locking screw threads. Locking screw


164


is subsequently tightened to lock shuttle


132


to clamp housing


124


.




Adjustable bracing structure


102


is secured to bathtub


18


by placing the inner pad


144


on the inside of the bathtub rim and clamp plate


148


on the outside of the bathtub rim with outer pad


152


in contact with the outer rim. Adjustment screw


160


is inserted through aperture


156


and is received by the adjustment screw threads. As adjustment screw


160


is tightened, clamp plate


148


moves closer to inner pad


144


, thus the distance, W, between inner pad


144


and outer pad


152


is reduced until W equals the width of the bathtub, preferably until a sufficient clamp force develops between the bracing structure and the bathtub rim to secure the bath seat against movement during bathing.




Once adjustable bracing structure


102


is secured to bathtub


18


, seat body


106


is connected to the adjustable bracing structure by lifting the seat body and sliding one of the flanges


120




a


and


120




b


into slot


140


. The height, H, between a bottom


168


of bath seat


100


and the bottom of the bathtub, can be adjusted by moving shuttle


132


up or down along channel


128


. By having flanges


120




a


and


120




b


, on each side, bath seat


100


can be mounted on each side.




Since bracing structure


102


is clamped tightly on the bathtub rim, bath seat


100


will be held securely in.




Clamp housing


124


and seat


106


components are fabricated using blow-molding techniques. Shuttle


132


, clamp plate


148


, and handle


162


components are fabricated using injection molding.




Recess


130


is used to store soap, sponges or shampoo. In other embodiments, other recesses may be added to bath seat


100


and used to store other bathing items.




In a third example of a bracing bath seat


200


, as shown in

FIGS. 3A-3D

, the bath seat is partially stabilized by a leg


202


that contacts the bottom surface of the bathtub. Bath seat


200


includes an adjustable bracing structure


204


, attached to an adjustable rail


214


, and a seat sling


216


, attached to the bottom of the adjustable rail.




Adjustable bracing structure


240


includes a shuttle


208


that is detachably connected to a clamp assembly


210


. Clamp assembly


210


includes a front piece


211


having an adjustable track


213


and a back piece


215


. Shuttle


208


is engaged to clamp


210


by sliding the shuttle along a channel


222


on back piece


215


. A spring-loaded button


230


on shuttle


208


is depressed prior to inserting shuttle


208


into channel


222


and remains depressed as the shuttle moves along the channel until the button aligns with one of a set of buttonholes


224


. Button


230


is released thereby locking shuttle


208


to clamp


210


. Shuttle


208


is disengaged from clamp


210


by pressing button


230


and moving the shuttle out of channel


222


. Thus, an adult can easily use the bathtub by pushing button


230


and removing the entire bath seat except for clamp


210


.




Adjustable rail


214


includes a front portion


218


and a back portion


220


attached together using a molded in track. Front portion


218


can be moved in a direction, F, away from back portion


220


along the molded track to adjust to the child's size.




Support leg


202


extends from back portion


220


opposite shuttle


208


. With bath seat


200


in an upright intended use position and resting on a horizontal surface, the bath seat contacts the horizontal surface only on one side of its center of gravity, C. Bath seat


200


is constructed to not remain in an upright, intended use position when resting on a horizontal support surface without placing shuttle


208


into clamp assembly


210


. This is intended to help deter the adult from placing the child in bath seat


200


unless and until the bath seat is secured to the rim of the bathtub. Support leg


211


includes a rubber bottom surface


240


to prevent slipping on a wet surface.




Attachment and adjustment of clamp assembly


210


to the side of the bathtubs of varying widths is accomplished by sliding back piece


215


along adjustment track


213


of front piece


211


. Adjustment track


213


allows incremental adjustment of clamp assembly


210


to the bathtub side. A center cam lock


212


is used for the final tightening of bath seat


200


to a tub outside wall by moving cam lock


212


in a Y direction.
