The first and second arms are pivotally attached to the tub about an axis displaced from the foot end of the tub into at least first and second positions. The front cross member is disposed above, and displaced from, the top side of the tub when the arms are in first position. An elongated member is attached to the front cross member at a first end and extends from the front cross member to a second end having a foot disposed below the foot end of the tub and adapted to engage a smooth surface. The elongated member extends toward the foot end of the tub to provide a passive crotch restraint for a child received by the tub when the arms are in first position.

Description

BACKGROUND OF THE INVENTION

The invention relates to a bathtub and bathseat combination and in particular to an apparatus for use interchangeably in a bathtub configuration and a bathseat configuration.

Children's bathtubs allow persons to bathe a child in a manner in which the child is safe and comfortable. These bathtubs are typically adapted to fit within an adult-sized bathtub, or even a sink. Persons can place the children's bathtub into the adult bathtub or the sink, fill the children's bathtub with water, put the child into the children's bathtub, and bathe the child.

Bathseats can also be used to bathe the child, with the child positioned in a seated, upright position. Typically, these seats are used for children that are at least a few months old and have enough neck strength to support their heads.

The invention provides an apparatus that can be used as a bathtub for bathing an infant and converted for use as a bathseat for bathing a child. The apparatus can be locked into the bathseat configuration to help guard against the apparatus accidentally shifting from the bathseat configuration to the bathtub configuration. The apparatus can be securely attached or mounted to the floor or hubs 55 of an adult-sized bathtub or attached or mounted at least partially within a sink.

As shown in FIGS. 1-2 , a bathtub-bathseat assembly 10 includes a tub or basin 12 , a substantially rectangular (see FIG. 3 ) arm 14 including two sides 16 and 18 connected by cross members 20 and 22 , and a front support 24 . Assembly 10 can be positioned in either the bathseat position, shown in FIG. 1 , or the bathtub position, shown in FIG. 2 . Assembly 10 is configured to be placed in a sink or placed within an adult-sized bathtub and mounted to the floor of the adult-sized bathtub. Rounded edges and corners of assembly 10 help prevent injury.

Tub 12 has a bottom wall 26 and side walls 28 and 30 (see FIG. 4 ) that provide a volume 32 . Volume 32 is configured for receiving a child. Bottom wall 26 is contoured to accommodate a child and includes a bottom/back rest 34 . Rest 34 includes a top portion 36 adapted so that an infant can sit on top portion 36 . Rest 34 also includes a front portion 38 adapted to provide back support to a child sitting on a surface region 40 (not shown in FIG. 2 ) of bottom wall 26 . Bottom wall 26 is integrally connected to side walls 28 and 30 such that tub 12 is adapted to hold water in volume 32 , especially when in the bathtub position. A drainage hole 33 is provided through bottom wall 26 (FIG. 3 ).

Referring to FIG. 3 , tub 12 has a head end 42 and a foot end 44 . At foot end 42 , a ledge 46 provides a recess 48 and includes an upwardly directed tab 50 . Ledge 46 and a foot end portion of bottom wall 26 also provide a hole 52 through ledge 46 and bottom wall 26 .

Referring also to FIG. 4 , tub 12 provides key holes 54 (only one is shown in FIG. 4 ) in exterior portions of each side of tub 12 . Key holes 54 do not extend through side walls 28 and 30 of tub 12 . Each key hole 54 has an upper circular hole 56 , centered along an axis 64 , and a lower slot 58 in fluid communication with hole 56 . As shown in FIG. 4 , slot 58 has a width 60 relatively smaller than a diameter 62 of hole 56 . Key holes 54 are located along the sides of tub 12 closer to foot end 44 than to head end 42 .

Arm 14 includes two sets of discs 66 and 68 integrally connected by shafts 70 (schematically shown in FIG. 3 ) that are adapted to be received by key holes 54 . Discs 66 and 68 and shafts 70 are centered on an axis 72 . Shafts 70 are configured to be slidingly received by slots 58 of key holes 54 in tub 12 and to be rotatingly received within holes 56 in key holes 54 . As shown in FIG. 5 , shaft 70 includes a plurality of ribs 76 arranged to effectively provide two flat sides indicated by lines 78 and two rounded ends 80 . Flat sides 78 are separated by a distance 82 approximately equal to, but slightly smaller than width 60 of slot 58 in tub 12 . Rounded ends 80 effectively provide the curvature of a circle 84 having a diameter 86 approximately equal to, but slightly less than, diameter 62 of hole 56 in tub 12 and larger than width 60 of slot 58 . Shafts 70 are schematically shown as rectangles with rounded ends in FIGS. 3 , 7 - 8 , and 10 .

Referring to FIGS. 3 and 5 , a ramp surface 74 is disposed adjacent the periphery of each disc 68 . Ramp 74 has a thin end 88 and a thick end 90 , with a flat top portion 92 .

Returning to FIGS. 1-2 , arm 14 is pivotally connected to tub 12 for movement about axis 64 .

Referring to FIGS. 6 and 6A , tub 12 includes vanes 94 (only one shown) forming part of key holes 54 (FIGS. 3 - 4 ). As shown in FIG. 6A (partially cut away with the portion of tub 12 shown in FIGS. 3-4 forming part of key holes 54 removed), vane 94 has a semicircular cutout 96 of the same diameter 62 as hole 56 ( FIG. 4 ) and is centered along axis 64 . FIG. 6 shows the relationship of discs 66 and 68 , and shaft 70 of arm 14 , to tub 12 . As shown, side 16 of arm 14 is disposed adjacent to tub 12 and, in particular, to a wall 100 (see also FIGS. 3-4 ) of tub 12 forming part of key hole 54 . Disc 66 is disposed adjacent to an opposite side of wall 100 from side 16 . Vane 94 is disposed between discs 66 and 68 . Shaft 70 extends through hole 56 and cutout 96 (FIG. 6 A). Vane 94 has a rib 98 disposed and configured to interfere with ramp 74 ( FIGS. 3 and 5 ) when arm 14 is pivoted about axis 64 .

Referring to FIGS. 1-3 , arm 14 is shaped and connected to tub 12 such that cross member 20 is disposed in front of tub 12 and cross member 22 is disposed behind tub 12 . Side 16 has a somewhat “Z” shape when viewed from the left side of assembly 10 and side 18 has a somewhat “S” shape when viewed from the right side of assembly 10 . Cross member 20 includes posts 106 (only one is shown in FIG. 3 ) in a trough 102 for receiving a toy 104 (FIGS. 1 - 2 ). A hole 118 is provided in the bottom of trough 102 to allow liquid to drain. Forward of hole 118 , shown in FIG. 3 with a portion of cross member 20 cut away, are two posts 120 (only one of which is (schematically) shown).

Referring to FIG. 3 , front support 24 includes a base 124 and a lever 126 . Two holes 122 (only one shown in FIG. 3 ) in base 124 are sized to pivotally receive posts 120 of arm 14 . Lever 126 includes two posts 125 (only one (schematically) shown in FIG. 3 ) adapted to be received by holes 127 in base 124 . Lever 126 has a top end 121 and a middle section 119 that are configured to be inserted through hole 52 in tub 12 and a bottom end 123 that is larger than hole 52 . Lever 126 is coupled to base 124 by a spring 128 and is pivotally received about holes 127 in an opening 130 in base 124 . Spring 128 is received by a tube (not shown) inside opening 130 of base 124 and receives a rod (not shown) extending from lever 126 . Spring 128 biases lever 126 to rotate about the center axis of holes 127 . Lever 126 includes an upwardly-extending tab 132 to interfere with an end wall 134 of opening 130 in base 124 . Lever 126 also includes a downwardly-extending tab 142 configured to be received by recess 48 in cross member 20 of tub 12 . Tab 142 extends downwardly further than tab 50 of tub 12 extends upwardly plus the depth of recess 48 .

Suction cups are attached to the bottoms of arm 14 and front support 24 for attaching to the floor of an adult-sized bathtub. Two suction cups 108 and 110 are mounted to the bottoms of junction 112 and 114 between cross member 22 and sides 16 and 18 , respectively. A suction cup 116 is mounted to the bottom of base 124 . The locations of the suction cups 108 , 110 , and 116 , as shown, provides stability to assembly 10 when, e.g., mounted, attached, or rested on a surface such as a bathtub floor.

A plug 136 is received by drainage hole 33 . Tabs 138 interfere with a bracket 140 (see also FIG. 2 ) on the bottom of tub 12 to inhibit rotation of plug 136 when received by hole 33 .

Assembly 10 is assembled as follows. Front support 24 is assembled by placing spring 128 in the tube inside base 124 and inserting lever 126 into opening 130 . Lever 126 is inserted such that posts 125 are received by holes 127 and spring 128 is received by the rod extending from lever 126 . Suction cup 116 is attached to the bottom of base 124 . Suction cups 108 and 110 are attached to the bottoms of junctions 112 and 114 of arm 14 . The top of support 24 is inserted through hole 52 in tub 12 and base 124 coupled to arm 14 with holes 122 of base 124 receiving posts 120 of arm 14 . As shown in FIG. 9 , arm 14 is rotated substantially perpendicular to tub 12 and slid over tub 12 as indicated by arrow 144 and up as indicated by arrow 146 such that shafts 70 have their flat edges 148 aligned parallel to the walls of slots 58 , allowing key holes 54 to receive shafts 70 as shown in FIG. 10 . Axis 72 of arm 14 thus is substantially aligned with axis 64 of holes 56 . Arm 14 is rotated as indicated by arrow 150 in FIG. 8 toward the bathseat position shown in FIG. 1 , with shaft 70 rotating to its bathseat position as shown in FIG. 8 . Ramp 74 ( FIGS. 3 and 5 ) ramps over rib 94 on disc 68 . Thick end 90 of ramp 74 inhibits rotation in a direction 190 opposite to direction 150 , thus inhibiting edges 148 of shafts 70 from realigning with slots 58 . Arm 14 is thus inhibited from being removed from tub 12 . Toy 104 is inserted into trough 102 with toy 104 being received by posts 106 . Plug 136 is inserted into drainage hole 33 .

In operation, assembly 10 can be positioned and used interchangeably in a bathseat configuration ( FIG. 1 ) and a bathtub configuration (FIG. 2 ).

With assembly 10 in the bathseat position, shaft 70 is in the position shown in FIG. 8 , and front support 24 is in the position shown in FIG. 11 (arm 14 not shown in FIG. 11 ). Front support 24 extends downwardly from cross member 20 through hole 52 of tub 12 to provide a passive crotch restraint for a child seated in volume 32 provided by tub 12 . As shown in FIG. 11 , bottom end 123 of support 24 is not inserted up through hole 52 in tub 12 , bottom end 123 being unable to fit through hole 123 . This helps prevent arm 14 from being rotated such that edges 148 of shafts 70 realign with slots 58 , thus inhibiting disassembly of arm 14 from tub 12 . Downwardly-extending tab 142 is received by recess 48 in tub 12 . Cross members 20 and 22 are separated from tub 12 .

In the bathseat position, as shown in FIG. 13 , assembly 10 can be mounted in an adult-sized bathtub 160 (shown schematically and out of scale). Suction cups 108 , 110 , and 116 ( FIG. 3 ) removably connect assembly 10 to the floor of the tub 160 , with sides 16 and 18 (not shown in FIG. 11 ) and cross member 22 providing support to assembly 10 . The tub 160 can be filled with water and a child placed in volume 32 as shown. The child sits on region 40 with the child's lower back resting against front portion 38 of rest 34 and the child's legs extending through openings 162 and 164 ( FIG. 1 ) between front support 24 , cross member 20 , ledge 46 of tub 12 , and sides of the tub 12 . Front support 24 serves as a passive crotch restraint in this position.

Assembly 10 can be repositioned from the bathseat position to the bathtub position. The child in volume 32 should be removed, and water in volume 32 drained by opening plug 136 . Referring to FIGS. 1 and 11 , cross member 20 is separated from tub 12 , lifting tab 142 from recess 48 as indicated by arrow 166 in FIG. 11 . (The weight of a child in volume 32 will inhibit separating cross member 20 from tub 12 .) Front support 24 is squeezed to push lever 126 into opening 130 . Tabs 142 and 50 and a wall of recess 48 inhibit lever 126 from being pushed into opening 130 unless front support 24 is moved upward in direction 166 to remove tab 142 from recess 48 . Cross member 20 is brought close to ledge 46 , such that support 24 moves through hole 52 in tub 12 in direction 168 shown in FIG. 12 , until arm 14 (shown schematically in FIG. 12 ) interferes with tub 12 . Shaft 70 rotates in direction 150 until it reaches its bathtub position shown in FIG. 7 .

In the bathtub position, as shown in FIG. 14 , assembly 10 can be mounted in a sink 170 (e.g., disposed in a counter 174 ). Tub 12 can be filled with water and an infant placed in volume 32 as shown with substantially the infant's entire body, including legs, being received by volume 32 . The infant sits on top portion 36 and uses the portion of bottom 26 between top portion 36 and head end 42 as a back rest. In the bathtub position, cross member 20 is adjacent foot end 44 of tub 12 and cross member 22 is closer to head end 42 of tub 12 than when in the bathseat position (FIG. 1 ).

To move assembly 10 from the bathtub position to the bathseat position, cross member 20 is separated from tub 12 . The infant should be removed, and the water drained by opening plug 136 . Separating cross member 20 from tub 12 causes shaft 70 to rotate in direction 190 as indicated in FIG. 7 and causes lever 126 to rub against a wall 172 ( FIG. 12 ) of hole 52 , causing lever 126 to be pushed into opening 130 . When tab 142 is disposed higher than tab 50 , spring 128 pushes lever 126 away from base 124 . Tab 132 on lever 126 hits wall 134 and stops pivoting of lever 126 . Support 24 is lowered such that tab 142 is received by recess 28 . Shaft 70 is again in its bathseat position shown in FIG. 8 .

Other embodiments are within the scope of the following claims. For example, a dumbbell-shaped shaft 180 shown in FIG. 15 can be used instead of shaft 70 . Hole 56 can rotatably receive shaft 180 if the length of the shaft 180 is aligned with the length of slot 58 .
