BACKGROUND
Infants, as well as some adults, have special care needs with respect to feeding, transportation, and hygiene. Focusing on hygiene, and bathing in particular, numerous products are available for use in bathing babies, including special tubs and bathing accessories. For example, FIGS. 1 and 2 show a portable baby bathtub that is small in scale, folds for storage or transport, and has an inclined surface to support the baby during the bathing process. However, parents who rely solely on this tub might have difficulties when away from the tub, and only a conventional baby tub or adult tub is available.
Accessories, such as bathing slings, are available for use in conventional tubs. FIG. 3 shows such a sling. The sling provides an inclined surface to support the baby, and a fabric surface that is comfortable and can be washed. This sling is placed in a tub, to support the baby while bathing, as shown in FIG. 4. However, these slings keep the baby at least partially submerged in the water at all times, are not contoured for a baby's comfort, and are not adjustable. They offer little more than an inclined surface for the infant

DESCRIPTION OF THE INVENTION
The present invention is a bathing apparatus, suitable for bathing infants.
According to an exemplary embodiment, the present invention is a support apparatus for placement within a bath tub. As shown in FIG. 5, such an apparatus includes a base 510 to provide stable support for the apparatus. A frame 520 is connected to the base 510. The frame 520 has an upper frame portion 522, a lower frame portion 524, and a brace portion 526. A cover 530 is removably attached to the frame 520 and forms an indented shape for supporting an infant.
Reference is now made to FIGS. 6 and 7.
According to an exemplary aspect of the invention, the base 610 is made from a lightweight material such as plastic. The underside 616 of the base 610 preferably includes an anti-skid surface to help prevent the base 610 from slipping on a wet surface. Thus, some type of anti-skid material having a higher index of sliding friction can be applied to the underside 616, such as by coating the surface or by adding a layer or appliqués of material such as rubber.
Preferably, the base 610 has at least one perforation 619 to make it easier to place the apparatus in a tub filled with water, and to make the apparatus lighter in weight and less costly to manufacture. As shown, the base 610 includes material around the periphery, and an aperture through an inner portion. Other configurations are contemplated, such as a grid arrangement or other structure having at least one vertical perforation.
Generally, in preferred embodiments, at least part of the frame 620 is removably attached to the base. This provides convenience in storage and cleaning of the apparatus. As shown in this example, a brace or other frame support 626 is attached to the rear portion of the base and to the upper portion of the frame. Also as shown in this embodiment, the brace 626 and the upper portion of the frame are coupled together by at least one junction member or other linkage device 628.
As shown, the brace 626 can be pivotally attached to the rear portion of the base and to the junction members 628, which can be slidably attached to the upper portion of the frame, and the upper portion of the frame can be pivotally attached to the front portion of the base. This arrangement allows the frame 620 to be adjustable in reclining angle, to accommodate the individual comfort requirements and various proportions of different infants. Likewise, lower portion of the frame is preferably pivotally attached to the front portion of the base such that lower portion of the frame is also adjustable.
For ease of portability, preferred embodiments of the frame 620 are also foldable. As shown, a top portion of the upper frame is pivotally coupled to the bottom portion of the upper frame, by way of the junction members 628.
As shown in FIG. 7, at least part of the cover 730 is constructed from at least one fabric. This fabric can be selected based on any of a number of factors, including its strength, durability, and comfort. Preferably, at least part of the cover 730 is formed of a material having elastic properties, to provide a secure fit in engaging the frame and for the comfort of the infant. Also for the infant's comfort, the cover 730 has a contoured shape when engaged with frame 620. For example, the exemplary embodiment shown in FIG. 7 includes a cover 730 that forms a “scoop” shape to cradle the infant in the bather. In this embodiment, the lowest portion of the cover 730 is positioned at a certain height above the base, to allow the infant to sit above a certain depth of standing water, such as when rinsing the infant.
Referring again to FIGS. 6 and 7, the apparatus of the present invention will be described in more detail. As shown, the apparatus includes a stable base 610, a frame 620 that is at least partially removably attached to the base 610, and a fabric cover 730 that is fitted over the frame 620, and can be removed for cleaning or replacement. The fabric cover 730 preferably is contoured, that is, it is fabricated from multiple panels of fabric to provide a three-dimensional, cradling shape, which is supported by the shape of the frame. The frame dimensions allow the lowest portion of the fabric cover 730 to be disposed at a certain height over the base 610, and therefore over the surface of the water, if desired, while bathing the infant.
FIG. 6 shows the base 610 and the frame 620 without the fabric cover. The base can be a molded plastic piece with a low profile and a footprint having roughly similar lateral and transverse dimensions. Preferably, the base footprint has an open inner area, to allow easy placement in a tub when the tub already has water in it.
The frame can be constructed of, for example, lightweight tubing made of plastic, or of aluminum or other metal. The frame includes a first U-shaped piece 612 that extends from footings 614 on the base 610. The first U-shaped piece 612 extends at an angle from the plane of the base, to provide an incline for the fabric cover. The first U-shaped piece 612 can be pivotally coupled to the footings 614, to allow for adjustment of the rearward angle. The first U-shaped piece 612 is supported by a frame support 626, which includes a linkage device 628 that is coupled to the first U-shaped piece 612. By sliding the linkage device 628 along the length of the first U-shaped piece 612, support is provided while the angle at which the first U-shaped piece 612 inclines is adjusted. The frame support 626 includes a brace that is pivotally coupled to the base 610. This pivotal coupling can be provided by fitting the brace to a slot in the back portion of the base 610, fitting the brace through a channel provided through the back end of the base 610, or positioning the brace against a lip 618 on the back portion of the base 610. As shown, the brace can be a U-shaped piece.
Alternatively, the first U-shaped piece 612 can include three pieces: a smaller U-shaped piece, extending outward from the linkage devices 628, and two straight extensions or spanners 622 that connect the linkage devices 628 to the front portion of the base 610, preferably at the footings 614 described above. In this embodiment, the smaller U-shaped piece, the spanners 622, and the brace can all be pivotally coupled to the linkage devices 628. Thus, folding the smaller U-shaped piece over onto the spanners 622 and folding the brace under the spanners 622 allows the apparatus to be put in a compact configuration for storage or transportation. The base 610 can include recessed portions along the sides to accommodate the folded-under brace, and the spanners 622, pivotally connected at the footings 614, can be folded down as well. The frame 620 includes a second U-shaped piece 624, which is pivotally connected at the front end of the base 610. The base 610 preferably includes two flanges 638 on which the second U-shaped piece 624 is supported. The second U-shaped piece 624 can be folded back for storage or transportation.
The fabric cover 730 is stretches over the frame, and therefore at least partially assumes the shape of the frame. The cover 730 also has a shape of its own, which partially defines the receiving area of the bather support. The fabric cover 730 can be made from any material, or any combination of materials, including cotton, nylon, and mesh. Preferably, the material is at least somewhat stretchy, so that it can be fitted snuggly over the frame. Further, the periphery of the fabric cover 732 can be elasticized, for a sure fit, and can be padded, for the comfort of the infant. Preferably, the material from which the fabric cover 730 is constructed is washable. The fabric cover can be formed from several flat panels that are attached together, preferably sewn, to provide a three-dimensional shape. Pockets can be formed in the cover at the front and rear, to accept the ends of the U-shaped pieces 612, 624 of the frame 620, to hold the cover 730 in place.
As shown in FIG. 7, additional features can be added to the fabric cover 730. For example, a contoured headrest 734 can be provided. This headrest 734 can be fabricated of a padded material, such as a foam rubber. Alternatively, the headrest 734 can be made of PVC, vinyl, or other material such that the headrest can be inflated, by way of a valved opening, pump, or other means.
