TECHNICAL FIELD
[0002] Embodiments of the technology relate, in general, to bathtub
closure systems, and in particular to bathtub closure systems
having a plug, cover, or door associated therewith.
BACKGROUND
[0003] It is well recognized that many people, because of advancing
age or infirmities, reach a stage in life where they cannot step
over the usual sidewall of a bathtub for bathing or showering in
the tub. It is, of course, possible to remove the bathtub and to
install a shower-system that does not require a user to step over
the usual bathtub sidewall. However, a less costly solution to the
problem of providing access to a shower is often found in cutting
out a portion of the bathtub sidewall and providing a replacement
insert that provides a much lower sidewall portion that the user
can easily step through to enter the bathtub. With this arrangement
the tub does not need to be removed, so the tub and the already
available shower unit discharging into the tub can be used and the
entire area where the tub is located does not need to be remodeled
and refinished.
SUMMARY
[0004] Embodiments described herein include a bathtub closure
system having a step, the step having a first side panel, a second
side panel, and an elongated platform defining a cavity, where the
cavity can be configured to facilitate ingress and egress into a
bathtub. The bathtub closure system can include a closure, where
the closure can be coupled with the step and can cooperate with the
step to form a substantially watertight seal when the closure is in
a closed position. The bathtub closure system can include a support
portion, where the support portion can be co-molded with the step
and have a substantially U-shaped configuration extending in a
generally downward direction from the step to support the step
during use.
[0005] Embodiments described herein include a bathtub system having
a step saddle, the step saddle having a first side panel, a second
side panel, and an elongated platform defining a substantially
U-shaped cavity, where the substantially U-shaped cavity can be
configured to facilitate ingress and egress into a bathtub. The
bathtub system can include a support portion, the support portion
can include a body having a first leg and a second leg projecting
in a substantially downward direction from the step saddle such
that the support portion can be configured to support the step
saddle during use. The bathtub system can include a plurality of
support members, where each of the plurality of support members can
have a substantially frustoconical shape and a top surface.
[0006] Embodiments described herein include a bathtub closure
system that can include a step, the step being substantially
hollow, where the step can include a first side panel, a second
side panel, and an elongated platform defining a cavity, where the
cavity can be configured to facilitate ingress and egress into a
bathtub. The bathtub closure system can include a hinged door,
where the hinged door can be coupled with the step and can
cooperate with the step to form a substantially watertight seal
when the hinged door is in a closed position. The bathtub closure
system can include a support portion, the support portion being
co-molded with the step and having a substantially U-shaped
configuration, where the support portion can include a first leg
extending in a generally downward direction, a second leg extending
in a generally downward direction, and a plurality of support
members, each of the plurality of support members having a
substantially frustoconical configuration and a top surface, where
the plurality of support members, the first leg, and the second leg
can define a support portion cavity.

DETAILED DESCRIPTION
[0079] Various non-limiting embodiments of the present disclosure
will now be described to provide an overall understanding of the
principles of the structure, function, and use of the apparatuses,
systems, methods, and processes disclosed herein. One or more
examples of these non-limiting embodiments are illustrated in the
accompanying drawings. Those of ordinary skill in the art will
understand that systems and methods specifically described herein
and illustrated in the accompanying drawings are non-limiting
embodiments. The features illustrated or described in connection
with one non-limiting embodiment may be combined with the features
of other non-limiting embodiments. Such modifications and
variations are intended to be included within the scope of the
present disclosure.
[0080] Reference throughout the specification to "various
embodiments," "some embodiments," "one embodiment," "some example
embodiments," "one example embodiment," or "an embodiment" means
that a particular feature, structure, or characteristic described
in connection with any embodiment is included in at least one
embodiment. Thus, appearances of the phrases "in various
embodiments," "in some embodiments," "in one embodiment," "some
example embodiments," "one example embodiment", or "in an
embodiment" in places throughout the specification are not
necessarily all referring to the same embodiment. Furthermore, the
particular features, structures or characteristics may be combined
in any suitable manner in one or more embodiments.
[0081] Described herein are example embodiments of apparatuses,
systems, and methods for bathtub systems, covers, closures, plugs,
and overlays. In one example embodiment, a bathtub closure system
can include a step, which can help to facilitate ingress to and
egress from a bathtub, and a barrier, which can combine with the
step to retain water within the bathtub. In some embodiments, the
bathtub can be retrofitted to include the step and in other
embodiments an opening, such as a U-shaped opening, can be molded
or otherwise manufactured with the bathtub. The step can be
configured to accommodate a variety of types of barriers, such as a
cover, a closure, a plug, or a combination thereof. In some
embodiments, the barrier can be removable. The barrier can be
positioned on the step, positioned adjacent to the step, or
otherwise placed in contact with the step or a portion thereof. In
some embodiments, the barrier can be secured to the step by a
friction fit, a retention mechanism, or one or a plurality of
fasteners, such as a clamp, magnet, or a plurality of screws. In
some embodiments, the barrier can include a seal, which can further
facilitate water retention within the bathtub.
[0082] Example embodiments described herein can allow a bathtub to
be easily converted from an accessible shower to a usable tub. For
example, a plug or closure can be used to seal an opening or
aperture in the sidewall of a tub using top-down screws or
fasteners. Additionally, or alternatively, the step saddle can
accept a variety of components including a plug, a plurality of
plugs, a door, or the like. For example, the step can have a
modular configuration where the same step can accept a plug, a
door, and/or accessories as desired by a user. The modular step can
be sold as a kit or separate components or accessories can be
purchased and/or used as needed.
[0083] The examples discussed herein are examples only and are
provided to assist in the explanation of the apparatuses, devices,
systems and methods described herein. None of the features or
components shown in the drawings or discussed below should be taken
as mandatory for any specific implementation of any of these the
apparatuses, devices, systems or methods unless specifically
designated as mandatory. For ease of reading and clarity, certain
components, modules, or methods may be described solely in
connection with a specific figure. Any failure to specifically
describe a combination or sub-combination of components should not
be understood as an indication that any combination or
sub-combination is not possible. Also, for any methods described,
regardless of whether the method is described in conjunction with a
flow diagram, it should be understood that unless otherwise
specified or required by context, any explicit or implicit ordering
of steps performed in the execution of a method does not imply that
those steps must be performed in the order presented but instead
may be performed in a different order or in parallel.
[0084] Example embodiments described herein can improve ease of
access to and from a bathtub while retaining a bathtub's ability to
retain a substantial volume of water. A bathtub system can include
a step, which can provide a lower clearance than a surrounding
bathtub wall for easy access. The step can facilitate ingress to
and egress from a bathtub by eliminating a potentially hazardous
high step that is associated with traditional bathtubs. Despite
this provision for a lower clearance, embodiments of the bathtub
system described herein can selectively accommodate a water level
substantially commensurate with the surrounding bathtub wall. The
bathtub system can include a barrier, which can establish a
clearance substantially similar to that of the surrounding bathtub
wall. The barrier can accommodate a higher water level than that
allowable by the step and can otherwise facilitate water retention
within the bathtub. The barrier can be removable such that easier
ingress to and egress from the bathtub can be permitted, for
example, before and after a bath or shower. The barrier can
include, for example, a plug, which can easily be placed on the
step, and/or a cover, which can easily be positioned adjacent to
the step. Alternatively, the barrier can be a permanent retrofit
that can substantially restore a bathtub with an opening or step to
the look and function of a traditional bathtub. For example, if a
home is sold where a bathtub having an opening or step is no longer
needed, a barrier can be permanently placed over or in the opening
such that the bathtub substantially looks and operates like a
traditional bathtub.
[0085] The examples discussed herein are examples only and are
provided to assist in the explanation of the apparatuses, devices,
systems and methods described herein. None of the features or
components shown in the drawings or discussed below should be taken
as mandatory for any specific implementation of any of these the
apparatuses, devices, systems or methods unless specifically
designated as mandatory. For ease of reading and clarity, certain
components, modules, or methods may be described solely in
connection with a specific figure. Any failure to specifically
describe a combination or sub-combination of components should not
be understood as an indication that any combination or
sub-combination is not possible. Also, for any methods described,
regardless of whether the method is described in conjunction with a
flow diagram, it should be understood that unless otherwise
specified or required by context, any explicit or implicit ordering
of steps performed in the execution of a method does not imply that
those steps must be performed in the order presented but instead
may be performed in a different order or in parallel.
[0086] Example embodiments described herein can allow a bathtub to
be easily converted from an accessible shower to a usable tub. For
example, a plug can be used to seal an opening or aperture in the
sidewall of a tub using top-down screws or fasteners. Additionally,
or alternatively, the step saddle can accept a variety of
components including a plug, a plurality of plugs, a door, or the
like. It will be appreciated that a plug, door, fitting, or the
like can partially or substantially block or close an aperture or
cavity defined by a step saddle. For example, the step saddle or
substantially U-shaped cutout can have an open position that can
allow ingress and egress from a bathtub, or can be closed with a

suitable mechanism to secure the plug 958 to the step 912. As shown
in FIG. 23, the inner cover 968 can be attached to the plug 958.
The plug 958 can include retention mechanisms 964, 965 that can
secure the plug 958 to the inner cover 968 with fittings 980, 982,
respectively. In one embodiment, the inner cover 968 can pivot
relative to the retention mechanisms 964, 965. In this manner, the
inner cover 968 can be adjusted to accommodate a range of steps or
bathtubs to create a watertight seal. The plug 958 can define
cylindrical apertures 982, 983 that can receive the retention
members 964, 965. Threaded fasteners 986, 987 can threadedly engage
the retention members 964, 965, respectively, such that tightening
the threaded fasteners draws the inner cover 968 towards the plug
958.
[0112] During use, the plug 958 can be inserted into the step 912
with the cover 968 loosely positioned interior of the step 912. The
step 912 can define cavities 978, 979, and the plug 958 can include
corresponding projections 981, 985. The cavities 978, 979 can be
configured to receive the projections 981, 985 of the plug 958 such
that, in the engaged position, the plug 958 can be interlocked with
the step 912. As a result, the cavities 978, 979 and projections
981, 985 can cooperate to prevent the plug 958 from being inwardly
or outwardly displaced from the step 912. The attachment recesses
or cavities 978, 978 can be channels, grooves, keyed slots, or the
like and can have a stop or abutment that engages the bottom of the
projections to prevent further movement. The projections or
attachment members can have any suitable shape, number, or profile
such as a semi-circle, block, tapered flange, or the like.
[0113] The plug 958 can include a handle (not shown) that can
facilitate vertical displacement of the plug 958 for removal from
the step 912. A suitable shape, size, or configuration of handle is
contemplated such as two offset and inset handles positioned
substantially perpendicular to the plug 958. After the plug 958 has
been positioned as shown in FIG. 22, the threaded fasteners 986,
987 can be rotated or otherwise actuated to draw the inner cover
968 towards the plug 958 such that the inner cover 968 and the step
912 form a substantially watertight seal.
[0114] FIG. 24 depicts an alternative embodiment of a bathtub
overlay system 1010. The bathtub overlay system 1010 can include a
bathtub 1012 and a corresponding plug 1058. The plug 1058 can
selectively cooperate with the bathtub 1012 to prevent water from
leaking during a traditional show or bath. It will be appreciated
that the tub 1012 can be independently molded or otherwise created
separately from the plug 1058. The tub 1012 can include a
substantially U-shaped cavity 1013 that can include an elongated
platform 1016, a first side panel 1018, and a second side panel
1020, where the elongated platform 1016 can extend between the
first side panel 1018 and the second side panel 1020. Each of the
first side panel 1018 and the second side panel 1020 can be
integral or of a unitary construction with a portion of the tub
1012 (e.g., a bathtub wall). In an engaged position, the U-shaped
cavity 1013, the plug 1058, and the cover 1068 can combine to
retain water within a bathtub. The plug 1058 can be selectively
removable from the U-shaped cavity 1013 to allow improved access to
and from the bathtub 1012. The bathtub 1012 can include an inner
surface 1030 and an exterior surface 1031.
[0115] The plug 1058 can include a first side 1060, a second side
1061, and a bottom portion 1062. The plug 1058 can include an

1060, the second side 1061, and the bottom portion 1062 can engage
the first side panel 1018, the second side panel 1020, and the
elongated platform 1016, respectively, such that the plug 1058 can
fit securely within the step 1012. The bathtub overlay system 1010
can include any suitable mechanism to secure the plug 1058 to the
bathtub 1012. As shown in FIG. 24, the inner cover 1068 can be
attached to the plug 1058. The plug 1058 can include retention
mechanisms 1064, 1065 that can secure the plug 1058 to the inner
cover 1068 with fittings 1080, 1082, respectively. In one
embodiment, the inner cover 1068 can pivot relative to the
retention mechanisms 1064, 1065. In this manner, the inner cover
1068 can be adjusted to accommodate a range of steps or bathtubs to
create a watertight seal. The plug 1058 can define cylindrical
apertures 1082, 1083 that can receive the retention members 1064,
1065. Threaded fasteners 1074 can threadedly engage the retention
members 1064, 1065 such that tightening the threaded fasteners 1074
urges or draws the inner cover 1068 towards the plug 1058.
[0116] During use, the plug 1058 can be inserted into the bathtub
1012 with the cover 1068 loosely positioned interior of the bathtub
1012. The bathtub 1012 can define cavities 1078, 1079, and the plug
1058 can include corresponding projections 1081, 985. The cavities
1078, 1079 can be configured to receive the projections 1081, 1085
of the plug 1058 such that, in the engaged position, the plug 1058
can be interlocked with the bathtub 1012. As a result, the cavities
1078, 1079 and projections 1081, 1085 can cooperate to prevent the
plug 1058 from being inwardly or outwardly displaced from the step
1012. The plug 1058 can include a handle (not shown) that can
facilitate vertical displacement of the plug 1058 for removal from
the bathtub 1012. After the plug 1058 has been positioned in the
U-shaped cavity 1013 of the bathtub 1013, the threaded fasteners
1074 can be rotated or otherwise actuated to draw the inner cover
1068 towards the plug 1058 such that the inner cover 1068 and the
bathtub 1012 form a watertight seal.
[0117] Any suitable bathtub, such as a molded tub with a
substantially U-shaped cavity, can include a cover, overlay, or
plug. For example, a cavity, U-shaped cavity, or step through can
be formed when a bathtub is molded or otherwise constructed. For
example, the tub 1012 illustrated in FIG. 24 can be molded as
illustrated, where any suitable corresponding overlay, such as plug
1058, can be provided separately. It will be appreciated that tubs
can be created, molded, or otherwise formed during manufacture to
accept any suitable cover, plug, or overlay, such as the
embodiments described herein. In one version, a U-shaped cavity in
a molded or manufactured tub can include apertures into which
lateral projections can extend to secure a plug to the tub. Tubs
can be configured with any suitable features, such as attachment
features, that can allow one or a plurality of different overlays
or inserts to be provided. It will be appreciated that a tub can be
molded or otherwise formed that can accept a number of different
types of covers, overlays, or plugs, where such a universal tub may
allow maximum flexibility for the association of different
components or features. In an example embodiment, the overlay or
plug can be inserted such that the plug or overlay fills a
pre-formed U-shaped cavity and looks substantially like a standard
bathtub wall.
[0118] FIG. 25 illustrates one version of a bathtub closure system
1110 that can include a bathtub 1113 and a substantially U-shaped
step 1112 that can be associated with a door 1114. The step 1112
can be formed with the bathtub, retrofit onto the bathtub,
associated with the bathtub during manufacturing, or otherwise
coupled or formed with the bathtub. The step 1112 can include an
elongate platform 1116, a first side panel 1118, and a second side
panel 1120, where the elongate platform 1116 can extend between the
first side panel 1118 and the second side panel 1120. The step 1112
can include an inner surface 1130 and an exterior surface 1131. The
elongate platform 1116 can have any suitable depth relative to the
bathtub 1113 where, for example, the top surface of the elongate
platform 1116 can be from about 6 inches to about 8 inches above
the bottom surface of the bathtub 1113. Providing a higher
threshold may help prevent water from spilling out of the bathtub
1113 during use.
[0119] FIG. 26 illustrates one version of a bathtub closure system
1210 that can include a bathtub 1113 and a substantially U-shaped
step 1212 that can be associated with a door 1214. The step 1212
can be formed with the bathtub, retrofit onto the bathtub,
associated with the bathtub during manufacturing, or otherwise
coupled or formed with the bathtub. The step 1212 can include an
elongate platform 1216, a first side panel 1218, and a second side
panel 1220, where the elongate platform 1216 can extend between the
first side panel 1218 and the second side panel 1220. The step 1212
can include an inner surface 1230 and an exterior surface 1231. The
elongate platform 1216 can have any suitable depth relative to the
bathtub 1213 where, for example, the top surface of the elongate
platform 1116 can be from about 2 inches to about 4 inches above
the bottom surface of the bathtub 1213. Providing a lower
threshold, such as for example lower relative to the embodiment
shown in FIG. 25, may help improve the ease of ingress and egress
from the bathtub 1213.
[0120] FIG. 27 illustrates one version of a bathtub closure system
1310 that can include a bathtub 1313 and a substantially U-shaped
step 1312 that can be associated with a door 1314. The step 1312

surfaces of the bathtub 1313. It will be appreciated that the step
1312 or threshold can be partially or entirely co-molded or
otherwise formed with the bathtub 1313 such that one or more of the
components are a unitary structure. Providing a substantially flush
exterior surface may improve the aesthetics of the bathtub 1313 and
may also reduce potentially hazardous surfaces, projections, and
the like that could contribute to a fall or injury. The step 1312
can be manufactured for a specific bathtub from a specific
manufacturer such that the step matches the bathtub in shape,
color, texture, gloss, or the like.

associated with a support portion 2880. The support portion can
have a substantially U-shaped configuration, having a bottom
surface 2882, that projects in a generally downward direction from
the step 2812. The bottom surface 2882 can be positioned or secured
to any suitable location to support the step 2812 such as on the
floor of a bathroom, on the bottom surface of a bathtub, on the
bottom surface of a bathtub within a cutout formed in the bathtub,
or any suitable surface or location. The bottom surface 2882 can be
associated with a flexible material, such as foam or a pad, that
can accommodate uneven surfaces or varying geometries in the bottom
of a tub or on the floor.
[0148] Referring to FIGS. 67-69, the support portion 2880 is shown
having a generally U-shaped configuration, but it will be
appreciate that any shape or configuration is contemplated. The
arch or U-shaped structure may provide the step 2812 with adequate
support while using a minimum of material, which may reduce product
costs. The support portion 2880 can be solid, can have a generally
V-shaped configuration, a T-shaped configuration, an inverted
T-shaped configuration, can taper inward at the width and/or the
length of the support portion, or have any other suitable shape.
The support portion 2812 can include a first leg 2884 and a second
leg 2886 that can be substantially vertical in orientation, spaced
apart, and substantially parallel to one another. The first leg
2884 and the second leg 2886 can be substantially identical in
configuration or, alternatively, one leg can be different from the
other leg to accommodate different bathtub geometries. The first
leg 2884 and the second leg 2886 can cooperate with a frustoconical
structure 2888 to define a support portion cavity 2890. The cavity
2890 can be substantially uniform along the length of the support
portion 2880 or vary in geometry for increased strength or for
other design considerations. It will be appreciated that ribs (not
shown), including a plurality of vertical or horizontal supports or
structures, or other structures can be provided or formed with the
support portion to support the step 2812. It will be appreciated
that the ends of the support portion 2880 can be closed such that
an internal cavity can be defined.
[0149] As illustrated in FIG. 68, the support portion 2880 can be
substantially hollow. The support portion 2880 can define an
internal cavity 2892 that can be empty or can be filled with
material such as support material, insulation, or the like.
Providing a large cavity 2892 may reduce the amount of material
needed to construct the step. In one embodiment, the step 2812 can
be inserted into a bathtub and then the internal cavity 2892 can be
filled with material after placement, such as support foam, to
provide additional strength to the step 2812. It will be
appreciated that the step can be formed without a cavity 2892 such
that the step and support portion 2880 are substantially solid.
[0150] Referring to FIGS. 68 and 69, the step 2812 and support
portion 2880 can include a plurality of frustoconical portions 2888
positioned along the length of the elongated platform 2816 of the
step 2812. Each of the frustoconical portions 2888 can include a
top surface 2894 that can be positioned adjacent to or in contact
with the bottom surface of the elongated platform 2816. In this
manner, the frustoconical portions 2888 can add support to the
elongated platform 2816 without the need for additional mass in the
step 2812 or support portion 2880. The frustoconical portions 2888
can be any support member, having any configuration, that can
provide support to the step and reduce the material requirements
for the step. The top surface 2894 of the frustoconical portions
2888 can be integral with the elongated platform, adhered to the
elongated platform 2816, or adjacent the elongated platform 2816
such that they function as a "kiss off" when force is applied to
the elongated platform 2816. For example, the top surface 2894 can
be spaced apart from about 1 mm to about 5 mm from the bottom
surface of the elongated platform. It will be appreciated that the
frustroconical portions can be any support member having any
suitable shape such as conical members, cylindrical members,
hexagonal members, cuboid members, or the like.
[0151] It will be appreciated that the support portions as
described herein can be used with any apparatus or device described
herein such as, for example, a step having a door. The support
portion can be a static structure or, in an alternate embodiment,
can have adjustable features such as telescoping legs. The support
portion can rest on a surface or, in an alternate embodiment, can
include fasteners that can be used to secure the step and support
portion. The support portion can have any suitable length and can
project downwardly from the bottom of the step, for example, from
about 2 inches to about 12 inches, from about 4 inches to about 6
inches, from about 3 inches to about 6 inches, from about 6 inches
to about 18 inches, from about 12 inches to about 24 inches, or any
suitable distance. The sized can be configured to reach the floor
of a bathtub. The width of the support portion can be from about 1
inches to about 8 inches, from about 2 inches to about 6 inches,
from about 4 inches to about 8 inches, or any other suitable
dimensions. The first leg and the second leg can have a width from
about 0.5 inches to about 2 inches, from about 1 inches to about
1.5 inches, or any other suitable dimension. The support portion
can have a length substantially matching that of the step or, in an
alternate embodiment, can have a shorter length than the step. It
will be appreciated that the step can be configured to accept a
range of support portions, such as in a kit, to accommodate a
variety of bathtub geometries.
[0152] It will be appreciated that any suitable features or
