The present invention relates to small, portable bathtubs useful in bathing infants and small children.
Bathtubs specifically designed and constructed for children are well known in the art. Among such bathtubs are small, stand-alone bathtub systems, support devices placed in a standard bathtub to support a child while being bathed, inflatable bathtubs, collapsible bathtubs relying on a preexisting full size bathtub for support, and bathtub systems operative to restrict the area of a standard bathtub commensurate with the relative size of the child.
According to the principle of the invention, a bathtub includes a base attached to a container. The base is movable between a collapsed position with respect to the container and a deployed position with respect to the container to support the container at an elevated location with respect to a support surface. The container is movable between a collapsed position with respect to the base and a deployed position with respect to the base to form an open tub to receive a child to be bathed. The base is movable between its collapsed position and its deployed position in the collapsed position of the container and in the deployed position of the container. The container is likewise movable between its collapsed position and its deployed position in the collapsed position of the base and the in the deployed position of the base. The container has a thickness in the collapsed position of the container. In the collapsed position of the base and the collapsed position of the container, the bathtub has an overall thickness substantially equal to the thickness of the container in the collapsed position of the container. Preferably, the container is mounted to the base for movement between a substantially horizontal position with respect to the base and an inclined position with respect to the base.
Referring to the drawings:
Turning now to the drawings, in which like reference characters indicate corresponding elements throughout the several views, attention is first directed to
Collapsible container 25 consists of an annular body, rim, or frame 30, and an attached tub. Frame 30 is formed of plastic, wood, metal, carbon fiber, or other similarly resilient and rigid material or combination of materials. Frame 30 is preferably integrally formed, but may be fashioned of a plurality of parts bonded or otherwise secured together, such as with adhesive, welding, heat bonding, etc. Snap fit, pin attachments, or other selected mechanical fasteners may be used to interconnect one or more preformed segments or structural pieces to form frame 30, if so desired. In the present embodiment, frame 30 has opposed upper and lower surfaces 31 and 32, and opposed continuous inner and outer marginal extremities 33 and 34. In the present embodiment, frame 30 is substantially oblong in shape as shown in the various figures. Upper surface 31 forms the upper side of frame 30, and lower surface 32 forms the underside of frame 30. Inner marginal extremity 33 encircles and bounds an opening 36. In the present embodiment, opening 36 is oblong or otherwise substantially oval in shape as illustrated.
In the present embodiment, the tub attached to frame 30 is formed by a sidewall 40 attached to a bottom 45. Sidewall 40 includes opposed continuous inner and outer surfaces 41 and 42, a continuous upper edge 43 affixed to continuous inner marginal extremity 33 of frame 30 and which also bounds and encircles opening 36, and an opposed continuous lower edge 44 affixed to a substantially rigid, and substantially bowl-shaped bottom 45. In the present embodiment, bottom 45 is formed of a substantially water impervious resilient and substantially rigid material or combination of materials, such plastic or other like or similar material or combination of materials, and sidewall 40 is formed of a substantially water impervious pliant, flexible, resilient material or combination of materials, such as waterproof cloth or cloth-like material, silicone or other like or similar rubber-like material or combination of materials, softened plastic, or the like. A continuous, resilient band denoted at 48 is formed in sidewall 40 at an intermediate position substantially equidistant and parallel with respect to upper and lower edges 43 and 44. Band 48 is formed of a plastic or other material or combination of materials having a resilient, flexible property. Upper edge 43 is affixed to continuous inner marginal extremity 33 with an aggressive adhesive, and may alternatively be affixed to continuous inner marginal extremity 33 by way of over molding, if possible, or with a mechanical fastening system or with mechanical fasteners, such as pins, rivets, clamping, etc. Lower edge 44 is likewise affixed to bottom 45 with an aggressive adhesive, and may alternatively be affixed to bottom 45 by way of over molding, if possible, or with a mechanical fastening system or with mechanical fasteners, such as pins, rivets, clamping, etc. Other techniques or systems may be used to affix or bond upper edge 43 to continuous inner marginal extremity 33 and lower edge 44 to bottom 45 according to the skill and knowledge attributed to the skilled artisan without departing from the invention.
Collapsible container 25 is overall substantially oblong in shape as illustrated, and has opposed front and rear ends generally denoted at 25A and 25B, respectively, and opposed sides generally denoted at 25C and 25D, respectively. Sides 25C and 25D are greater in length compared to the lengths of ends 25A and 25B. Legs 21 and 22 are attached to frame 30 at sides 25C and 25D, respectively, of collapsible container 25, and are parallel with respect to each other. Legs 21 and 22 are identical in structure and function. As such, only the details of leg 22 will be discussed, with the understanding that the ensuing discussion of leg 22 applies in every respect to leg 21.

Leg 22 has a length that is substantially equal to the length of collapsible container 25 from front end 25A to rear end 25B, and is movable between a collapsed or closed position with respect to collapsible container 25 in juxtaposition with respect to lower surface 32 or the underside of frame 30 as illustrated in
Leg 22 has a curvature that conforms substantially to the curvature of frame 30 under which leg 22 resides, and partially encircles sidewall 40 in juxtaposition with respect to the attachment of sidewall 40 to and extending along frame 30. In the deployed or open position of leg 22, leg 22 extends downward from the underside of frame 30 at side 25D of collapsible container 25 from intermediate portion 53 to outer ends 51 and 52 to be positioned upon a support surface. Leg 22 pivots between its collapsed and deployed positions, and a pivotal coupling formed between intermediate portion 53 and frame 30 is provided to not only attach leg 22 to frame 30 but also allow pivotal movement of leg 22 between its collapsed and deployed positions. A detent locking mechanism or system or the like is applied between leg 22 and frame 30 to secure leg 22 in its collapsed position and to secure leg 22 in its deployed position.
In the collapsed or closed positions of legs 21 and 22, legs 21 and 22 are considered disposed in their stored positions. In the deployed or open positions of legs 21 and 22, legs 21 and 22 are considered in deployed in their operative positions, wherein outer ends 51 and 52 of legs 21 and 22 may be positioned upon a supporting surface for supporting collapsible container 25 at an elevated location in preparation for use of collapsible container 25 in washing a small child or baby. As a matter of illustration and reference,
Legs 21 and 22 provide a stable supporting platform for collapsible container 25. In this particular embodiment, legs 21 and 22 are movable between their collapsed and deployed positions in both of the collapsed and deployed positions of collapsible container 25, and collapsible container 25 is movable between its collapsed and deployed positions in both of the collapsed and deployed positions of legs 21 and 22. In other embodiments constructed and arranged in accordance with the provisions of the invention provided by this disclosure, legs 21 and 22 need not be movable between their collapsed and deployed positions in both of the collapsed and deployed positions of collapsible container 25, and collapsible container 25 need not be movable between its collapsed and deployed positions in both of the collapsed and deployed positions of legs 21 and 22. Although a pair of opposed legs 21 and 22 are utilized in connection with the preferred embodiment disclosed herein, more can be provided without interfering with the preferred use and operation of bathtub 20 without departing from the invention. Also, legs 21 and 22 may each be divided or otherwise provided as two pivotally attached legs, if so desired.
As previously mentioned, collapsible container 25 is movable between a collapsed or closed position as illustrated in
As previously mentioned, sidewall 40 is formed of a pliant, flexible, resilient material or combination of materials, and is formed with continuous, resilient band denoted at 48 formed in sidewall 40 at an intermediate position substantially equidistant and parallel with respect to upper edge 43 of sidewall 40 affixed to frame 30 and lower edge 44 affixed to bottom 45. Band 48 is biased circumferentially outward, and imparts circumferential structural rigidity to sidewall 40. This structure of sidewall 40 in conjunction with bottom 45, and the elasticity of sidewall permits movement of the tub formed by sidewall 40 and bottom 45 between a closed or collapsed position in
In the collapsed position of continuous sidewall 40 and bottom 45 of container 25 as illustrated in
To move sidewall 40 and bottom 45 from its collapsed position to its deployed position, one need only apply a gentle force to the tub, such as to bottom 45 of the tub, sufficient to influence sidewall 40 to extend sidewall 40 downwardly moving bottom 45 downwardly and away from the underside or lower surface 32 of frame 30 unfolding pleats A and B until sidewall 40 is completely extended as illustrated in
According to this disclosure, bathtub 20 is movable between a collapsed or closed position in the collapsed or closed positions of collapsible container 25 and legs 21 and 22 as illustrated in
After bathing is complete, bathtub 20 may be rinsed and dried, and moved from its deployed position to its collapsed position as illustrated in
In accordance with a preferred embodiment, frame 30 of collapsible container 25 is preferably mounted to intermediate portions 53 of legs 21 and 22 for pivotal movement with respect to legs 21 and 22 as indicated by the double arcuate arrowed line C in
The ability to tilt collapsible container 25 into a raised or inclined position as illustrated in
The locking mechanism formed between each of legs 21 and 22 and frame 30 of collapsible container 25 includes a detent locking mechanism defining different locking points between collapsible container 25 and legs. If desired, a ratchet-style locking mechanism or other similar or like locking mechanisms can be used to secure collapsible container 25 at its inclined and horizontal positions with respect to legs 21 and 22 and at one or more selected positions therebetween without departing from the spirit and scope of the invention. If desired, the locking mechanism formed between each of legs 21 and 22 may be formed with or otherwise associated with a tab, switch, or other indicator to indicate the locked position of the locking mechanisms to ensure a caregiver preparing to wash a baby or small child that bathtub 20 is secured in ready for safe use.
The invention has been described above with reference to a preferred embodiment. However, those skilled in the art will recognize that changes and modifications may be made to the embodiment without departing from the nature and scope of the invention. For instance, sidewall 40 and bowl 45 together forming the deployable tub or basin of bathtub 20 can be formed from a contiguous or integrated piece of waterproof cloth, softened plastic, elastomer, rubber or rubber-like material, or the like, without departing from the invention. Also, although collapsible container 25 is overall substantially oblong or oval in shape as provided by the corresponding oblong or oval shapes of frame 30 and the tub formed by sidewall 40 and bottom 45, other shapes can be employed, such as round, rectangular, etc. Furthermore, although legs 21 and 22 are attached to frame 30 of collapsible container 25 at sides 25C and 25D, respectively, they may be attached to frame 30 at other locations, such as ends 25A and 25B, respectively. Moreover, although sidewall 40 is formed with one band 48, sidewall 40 can be formed with a plurality of parallel, spaced apart bands formed in sidewall 40 between and parallel with respect to upper and lower edges 43 and 44 of sidewall.
Various further changes and modifications to the embodiment herein chosen for purposes of illustration will readily occur to those skilled in the art. To the extent that such modifications and variations do not depart from the spirit of the invention, they are intended to be included within the scope thereof.
