BABY CHANGING MAT

Field of the Invention

The invention rdatcs to a baby changing mat.

Background

Baby changing mats exist comprising a suitably shaped piece of material providing an impermeable surface onto which a baby can be laid for changing of its nappy.

Sometimes babies urinate and defecate whilst positioned on the mat, leading to a mess on the changing mat. As well as dirtying the mat, this may soil the baby and the baby's clothes, as well as run over cdgcs of thc mat onto othcr surfaces. Some baby changing mats have side walls that prevent urine from spilling over side edges.

it is an object of the present invention to improve on known baby changing mats to address at least in part the above-mentioned issues.

Summary of the Invention

In accordance with a first aspect of the present invention, there is provided a baby changing mat comprising a sump means arranged so that. liquid on a baby support surface drains into the sump means.

Liquid, such as urine, on the baby support surfacc can then drain away quickly rathcr than remaining on the baby support surface. This is advantageous because it means that a baby does not lie in its own urine. If the baby is partially clothed, it also prevents or reduces the amount of urine/faeces that is absorbed by clothes. Also, it prevents urine/faeces from spilling from the baby changing mat in an uncontrolled manner.

The baby changing mat may further comprise a support means providing the baby support surface.

Conveniently, the sump means may be removable from the support means for emptying and can be relocated with the support means so that liquid on the support surface can drain into the sump means.

The sump means and the support means are preferably respectively configured for the sump means to engage with the support means.

The baby changing mat may further comprise at least one aperture therethrough from the baby support surface to the sump means to peimit drainage of liquid from the baby support surface into the sump means.

A lip may depend from the materia' of the support structure forming the aperture. the lip extending at least partially around the aperture. so that liquid from the support surface drains over the lip into the sump means.

The support surface of (he support means may be sloped when the mat is located in a use position on a horizonta' surface, the slope extending downwardly towards the sump means to facilitate flow of liquid into the sump means.

The support means may comprise at east one support member to provide said slope.

The at least one support member may be moveable between an extended configuration in which the support surface of the support means is sloped, and a collapsed configuration in which the support means is substantially flat. This may resull in the mat being smaller for easier transportation and storage.

The baby changing mat may further comprise at least one channel in the baby support surface, arranged to facilitate flow of liquid to the sump means.

The baby changing mat may comprise side walls respectively extending at opposite side edges of the baby support surface to prevent flow of liquid over said side edges.

The support portion may be formed in a mould as a single piece of material.

The baby changing mat may comprise at least one end wall to contain liquid.

The baby changing mat may further comprise at least one strap for restraining a baby lying on the support surface.

At least one recess may be provided in an outer surface of the support means through which the strap extends, for preventing slipping of the at least one strap.

There may be further provided apparatus comprising: the baby changing mat of any one of the preceding claims; a shielding arrangement for substantially blocking urine projected by a male baby lying on the changing mat.

The shielding arrangement preferably comprises a shield means and a mounting means to which the shield means is attached, wherein the mounting means is alTanged to hold the shield means for said blocking.

The shielding arrangement may he carried by the sump means. The shielding arrangement may be removable with the sump means.

Detailed Description of Embodiments

Like reference numerals are used to denote like parts throughout.

Certain terminology will he used in the foflowing description for convenience and reference only and should not be considered as limiting. For example, a baby changing mat has a conventional orientation and the words "upper", "lower", "side", "underside", "bottom", "top", "front" and "hack" are to he construed in view of that orientation.

Referring to Figures 1 to 8, a baby changing mat comprises a support structure 10 and a sump means in the form of a removable container 12. The support structure 10 provides a substantially rectangular, impermeable, slip-resistant support surface on which a baby can be laid. Although not essential to the invention, the material is preferably at least slightly resiliently deformable for comfort of the baby. The support structure 10 has smooth, easily wipeable surfaces that do not retain bacteria.

The support structure 10 has a p'anar underside lob, which is located on a fiat underlying surface when the changing mat is to be used. The support structure 10 includes side walls 14a, 14b extending at longitudinal edges of the support surface to contain liquid on the support surface.

The support structure 10 need not provide a substantially rectangular support surface.

The support surface needs to be of a size and shape to receive a baby. For example. the support surface could he oval.

The support structure 10 includes a recess 16 therein in which the removable container 12 can be located as shown in Figure 2. The removable container 12 can be slid in and out on the underlying surface. The recess 16 is below the support surface. An aperture 18 is provided in the support structure 10 between the support surface and the recess 16, so that liquid, for example urine/faeces, on the support surface can drain through the aperture 18 into the removable container 12. In modified embodiments, more than one aperture may he provided extending between the support surface and the recess 16 for drainage of liquid on the support surface. In other modified embodiments, the shape of the one or more apertures may differ to that shown. The location of the aperture may also differ to the location shown.

in a variant embodiment, the removable container 12 may be locatable underneath the support structure 10, such that the support structure 10 has to he lifted to permit removable of the container 12.

As best seen in Figure 7, a lip 32 depends from and around the lower edge of the aperture 18. This prevents collection of draining liquid on the support structure 10 above the removable container 12 due to surface tension.

The support structure 10 is sloped so that Uquid on the support surface flows to a thwer end of the support surface, the aperture 18 being located at said lower end. The aperture 18 and the lower end are located at a front of the support structure, and a baby's feet are in the vicinity when the mat is in use.

The support surface has an arrangement of channels therein to guide flow of the urine/faeces to the aperture 18. A channel 20a is located to extend substantially longitudinally with the generally rectangular support surface and extends to open into the aperture 18. Several other channds 20h-e extend from the first channel 20a outwardly in the support surface, towards the side walls 14a, 14b. A pair of further channels 20f. 20g each extend along the lower end of the support surface from the aperture 18 to, respectively, close to the first or second side walls 14a, 14b. The further channels 201. 20g are located so that liquid in the vicinity of the lower end of the support surface will drain under gravity into the further channels, and from there into the aperture 18. Thus the further channels 20L 20g substantially prevent any undesirable pooling of liquid at the lower end of the support surface.

The support structure 10 includes a top wall 22a and a bottom wall 22b. The top wall 22a extends between top ends of the side walls 14a. 14b and the bottom wall 20b extends between bottom ends of the sidewalls 14a. 14b. Each of the top and bottom walls 22a. 22h is contiguous with the support surface so as to contain liquid, so that liquid cannot leak between the tops and bottom walls and the support surface.

The removable container 12 is in the form of a substantially semi-circular tray that can be located in the recess 16 so that a front side of the baby changing mat is planar. The container 12 has a base 12a that rests on the underlying fiat surface. The removable container 12 is sized to be able to receive urine/faeces from a baby without overflow.

As can be seen in Figure 2, a gap 28 is provided between a top edge of a back wall I 2h of the container 12 and an upper surface of the recess 16, to enable a person to locate one or more fingers over the edge of the container 12 and thus to pull out the container 12 from the recess 16.

The support structure 10 and the removable container 12 include a means permitting attachment of the removable container 12 to the support structure 10. As shown in Figure 1, the removable container 12 includes a recessed portion 24a, 24h in each side of the container 12. The support structure 10 includes resiliently deformable projections 26a, 26b arranged so that when the container 12 is located in the recess 16, the projections extend into a respective one of the recessed portions 24a, 24b. The container 12, when located in the recess 14 with the projections 26a, 26b extending into the recesses 24a. 24h. will then he stahk and will not disthdge from the support structure if the baby changing mat is knocked.

Alternative means permitting attachment may he provided in variant embodiments.

Other forms of clip are known to persons skilled in the art. For example, side walls of the container may be dimpled with corresponding projecting portions on the surface of the recess engaging in the dimples. Alternatively, no means attachment permitting means maybe provided, in which case the support structure 10 and the container 12 are just suitably collocated for use with the container 12 resting on the underlying surface.

A handle 30 is provided in the back wall of the support structure 10 to facilitate carrying and tipping.

In alternative embodiments, the container 12 is not removable, but is permanently attached to or integrally formed with the support structure 10.

The support structure 10 and the container 12 may be formed of various materials and using various manufacturing techniques, as will be clear to a person skilled in the art.

The support structure may be formed of a single piece of open-cell or closed-cell foam by injection moulding in a mould. Where the material is an open-cell foam, the mould may be pre-sprayed with a material to form an impermeable skin on the surface of the open-cell foam. Alternatively, the support structure 10 maybe cut from a piece of open-cell foam and a plastic sheet cover applied and welded at seams. The support structure may be formed from other materials, for example. polymer, polystyrene, neoprene, plastic material or other suitable material. In embodiments where the container is attached to or integrally formed with the support structure, the container is preferably formed of the same material as the support structure. Where the container is removable.

it may be formed of the same material as the support structure in a separate process, or another material, for example a hard plastic material.

In use, a baby is laid on the baby changing mat with a head of the baby in the vicinity of the upper end and the feet of the baby in the vicinity of the lower end. When the baby urinates, urine/faeces flows down the sloping support surface into the aperture 18.

The channels 20a-g guide the urine/faeces towards the aperture 18. The side walls 14a, 14h prevent the urine/faeces from spilling over side edges of the support surface. The urine/faeces flows through the aperture 18, over the lip 32, into the removable container 12.

The container 12 is then removed, as shown in Figure 1. 6 and 7. To do this, the user pulls on the container 12 and the projections 26a. 26b disengage from the recessed portions 24a, 24b. The container 12 is then emptied, preferably wiped clean, and returned to its place in the recess 16 of the support structure 10, with the projections 26a. 26b engaging in the recessed portions 24a, 24b.

In the alternative embodiment in which the container is not removable, urine/faeces can he emptied from the container by wiping or sponging the surface of the container or moving the whole changing mat including the container to a disposal and cleaning location, for example a toilet and sink.

Although suitable for use with niae and female babies, embodiments of the invention described above are particularly useful with female babies since with a female baby located on her back on the baby changing mat, collection of urine/faeces will be more effective.

Referring now to Figures 9 to 14, embodiments will now be described that are particular'y suitable for male babies. These embodiments include the same elements as the embodiments described with reference to Figures ito 8. but further include a shield mounted to prevent urine/faeces projected upwardly from a male baby reaching a person in the process of changing the baby's nappy, In the embodiment shown in Figure 9, the mount includes a projecting portion 42 of the container 12 and a curved mounting arm 44 fixedly attached at a first end thereof to the projecting portion 42. The projecting portion 42 includes a recess into which the first end of the arm 44 extends and in which the arm 44is adhered, although the arm 44 may be otherwise attached to the container 12. The shield 40 is fixedly attached to a second end of the arm 44. The arm 44 extends to hold the shield 40 in a position to block projected urine/faeces.

The mount is generally shaped to taper from a portion remote from the front of the mat, to a portion thereof nearest the front of the mat.

Since the shield 40 is carried by the container 12, the shield is removable with the container. This facilitates cleaning.

The shield can he otherwise mounted, as now described with reference to separate embodiments respectively shown in Figure 10 to 12, 13 and 14. Referring to Figures to 12, the mount is an arm 44a having a first end attached to the support surface of the mat. The second end of the arm 44a attaches to a side 40a of the shield 40.

In the embodiment shown in Figure 13, a first end of an arm 44b is attached at a side wall 14a of the mat. The side wall 14a has a hole therein into which the first end extends.

The arm 44b nrny be attached to the wall in a manner that allows pivoting, so that the location of the shield 40 can he selected. Like in the embodiment previously described, the second end of the arm 44b attaches to a side 40a of the shield 40.

Referring to Figure 14. a first end of an arm 44c niay be attached to a support plate 46, which is not attached to the mat. The support plate 46 may sit adjacent the mat.

Optionally, the support plate 46 may extend underneath the mat for improved support of the shield 40.

The aim 44, 44a, 44b, 44c is preferably formed of a flexible material so that a user can move the shield 40 to different positions. In this way, location of the shield can be selected in view of the dimensions and position of the baby, and also to move the shield out of the way when a baby is being placed or removed from the support surface.

After being flexed, the material of the arm is preferably such that the arm stays in the position to which the user has flexed it. In variant embodiments, the arm 44, 44a, 44b, 44c can he adjustable to enable the position of the shield 40 to he changed using other techniques known to the skilled person, for example by implementing a hinge arrangement.

in use, the shield 40 is positioned so that, in (he event that a male baby urinates, projected urine is blocked and so does not reach the person changing the baby's nappy or the areas of the room immediately surrounding the mat. The user should position the shield 40 such that liquid reaching the shield 40 drains onto the support surface and continues into the container 12.

Optionally, one or more straps (not. shown) may be provided to prevent a baby from crawling or rolling from the support surface. Holes may be provided in the side wails 14a, 14h through which the one or more straps may extend. Allernatively, one or more channels or recesses may be provided in one or niore portions of the outer surface and/or top surface and/or bottom surface of the side walls l4a. 14b, for example, in which a strap may be located. The channels impede movement of the straps relative to the length of the mat. Preferably, the strap is adhered into the channel or recess.

It will be appreciated by persons skilled in the art that various modifications are possible to the embodiments. For example, the channels are an inessential yet preferred feature of the baby changing mat. There are also many other ways in which such channels can be arranged. Also, the form of the support structure may be different; for example the rear may be raised on one or more one or more support. members, such as legs, to provide a slope. Such one or more legs may be pop-up or pivotable, so that the mat is collapsible.

it is also not essential to the invention that the baby changing mat is sloped. Where a baby changing mat in accordance with embodiments is not sloped, a user may tip the mat so that any liquid on the support surface flows to the container 12.

Further, in variant embodiments, the support surface may curve along its width, that is, between the two side walls 14a, 14b, to result in better flow of liquid on the support surface towards the aperture 18. For example, since the aperture 18 is centrally located, a U-shaped curve may usefully improve drainage. There may also be curvature aiong the length of the mat to improve drainage or to improve comfort for a baby. Particifiarly in such variant embodiments, the channels described above may be superfluous. Where there is curvature along the length of the width of the mat, the shape of the surface of the mat is preferably chosen taking into consideration the comfort of the baby.

Where the word "nappy" is used herein, the word "diaper" should be understood as equivalent.

The applicant hereby discloses in isolation each individual feature or step described herein and any combination of two or more such features, to the extent that such features or steps or combinations of features and/or steps are capable of being carried out based on the present specification as a whole in the light of the common general knowledge of a person skifled in the art, irrespective ol whether such features or steps or combinations of features and/or steps solve any problems disclosed herein, and without limitation to the scope of the claims. The applicant indicates that aspects of the present invention may consist of any such individual feature or step or combination of feamres and/or steps. Tn view of the foregoing description it will he evident to a person skilled in the art that various modifications may be made within the scope of the invention.
