BACKGROUND
Field of the Invention
[0001] The present invention relates generally to raised toilet seats, and in particular,
to a raised toilet seat assembly with improved coupling features to the underlying
standard toilet seat.
Description of Related Art
[0002] Certain people may experience difficulty in bending, sitting and/or standing for
various reasons. Often elderly people start to experience symptoms of arthritis or
general muscle atrophy as they age. Youthful people may have injuries, or side effects
from surgery (e.g., hip surgery) that make it difficult to sit and stand. For example,
it may be difficult for such persons to sit on, and/or stand up from, a toilet seat
that is low to the ground.
[0003] Specialty products have been designed to assist people that have difficulty sitting
or standing. Such specialty products include rails mounted to the floor or the wall,
and raised toilet seats, among other things. Raised toilet seats work by increasing
the height of the toilet seat above the ground, and providing an inclined contour
to the top of the raised toilet seat, making it easier for people to sit without extreme
bending, and likewise making it easier for them to return to a standing position.
[0004] Current designs for raised toilet seats offer means for coupling the raised toilet
seat to a conventional toilet. These coupling means can make use of existing attachment
methods for attaching the raised toilet seat to the rim of the toilet, but such means
tend to be overly complex, making assembly/disassembly of the raised toilet seat a
difficult and tedious endeavor. Other less-secure means for coupling tend to offer
a raised toilet seat that is unstable when coupled to the toilet, which can increase
the risk of injury to a person using the raised toilet seat.
[0005] Furthermore, current methods of manufacturing raised toilet seats include blow molding
and rotational molding techniques, which can have certain drawbacks, such as requiring
much more material than is needed for the manufacture of the parts themselves, difficulty
achieving high levels of production, and difficulty maintaining desired tolerances
across products.

DETAILED DESCRIPTION
[0025] Referring to Fig. 1, there is illustrated a raised toilet seat assembly 100 according
to an example embodiment. The raised toilet seat assembly 100 is shown from a perspective,
exploded view and is intended for use with a toilet 102, such as a conventional toilet.
The raised toilet seat assembly 100 comprises an adapter plate 104 configured to removably
couple to the toilet 102 at a rear portion of the toilet 106, a shoe 108 configured
to removably couple to the adapter plate 104, and a raised toilet seat 110 configured
to removably couple to the shoe 108 at a rear portion of the raised toilet seat 112.
The toilet 102 may be any standard toilet with fasteners to couple a standard lid
to the toilet 102, the fasteners including, but not limited to screws, bolts with
corresponding nuts, etc. The toilet 102 is shown and described herein in only as much
detail as necessary to understand the present invention.
[0026] In some embodiments, the shoe 108 engages the adapter plate 104 by slidably coupling
with the adapter plate 104 via an interference fit relation. The shoe 108 also engages
with the raised toilet seat 110 by slidably coupling with the raised toilet seat 110
via an interference fit relation. That is, portions of the shoe 108 may each be slidably
coupled to the adapter plate 104 and the raised toilet seat 110, respectively, in
a manner of an interference fit relation whereby the coupled components are securely
coupled by the force of friction without the need for additional fastening elements.
This coupling allows for assembling/disassembling the raised toilet seat assembly
100 with greater ease, allowing for each component part of the assembly to be easily
separated or detached from the other component parts of the assembly, and therefore
enabling quick interchangeability which may be useful for preparing the toilet for
guests who do not require the raised toilet seat assembly 100. Although the illustrated
examples herein show coupling between the component parts of the raised toilet seat
assembly 100 via an interference fit relation, it is to be appreciated that other
means of coupling the shoe 108 to the adapter plate 104 and/or to the raised toilet
seat 110 will be apparent to a person having ordinary skill in the art. Importantly,
the raised toilet seat assembly 100 of the present invention does not require additional
fastening elements beyond the component parts (i.e., the adapter plate 104, the shoe
108 and the raised toilet seat 110) in order to fully assemble the raised toilet seat
assembly 100 and attach it to the toilet 102.
[0027] It is to be appreciated that the specific dimensions, proportions, shapes and configurations
of each of the adapter plate 104, the shoe 108 and the raised toilet seat 110 are
not specific to the present invention. For example, the raised toilet seat 110 may
be shaped or contoured in various ways to provide a suitably inclined top surface,
and the raised toilet seat 110 may be of various sizes, or heights, for a particular
toilet configurations such that the adapter plate 104 and the shoe 108 may be of a
suitable size to accommodate the coupling of the raised toilet seat 110 to the shoe
108 and to accommodate the coupling of the adapter plate 104 to the toilet 102.
[0028] In some embodiments one or more of the adapter plate 104, the shoe 108 and the raised
toilet seat 110 may be made of plastic, such as molded plastic, or any other suitable
material known in the art. Specifically, acrylonitrile butadiene styrene (ABS), or
a suitable polymer, such as polyethylene, and the like, may be used in the manufacturing
of the component parts of the raised toilet seat assembly 100. Suitable materials
may be rigid or semi-rigid, waterproof, and/or resistant to chemicals, heat and stress.
Additionally, the adapter plate 104, the shoe 108 and the raised toilet seat 110 are
preferably separate units that are operably interconnected.
[0029] In some embodiments, one or more of the adapter plate 104, the shoe 108 and the raised
toilet seat 110 may be manufactured using an injection molding technique, the process
for which should be apparent to a person having ordinary skill in the art. By using
an injection molding method to manufacture the adapter plate 104, the shoe 108 and/or
the raised toilet seat 110, minimal material is used for the manufacture of the component
parts, thereby preventing excess waste of material. Furthermore, injection molding
techniques allow for easily forming the open cavity, or recess, on the underside,
rear portion of the raised toilet seat 112, as will be explained in more detail, below.
[0030] Referring now to Fig. 2, an adapter plate 104 according to an example embodiment
is shown in further detail. As illustrated, the adapter plate 104 comprises a predominantly
flat, rectangular main body portion 202. The main body portion 202 includes a slot
204 configured to receive a portion of the shoe 108 shown in Fig. 1 when coupled thereto.
The slot 204 is shown in Fig. 2 as a recess, or cutout, of the main body portion 202
and is shown in an open configuration. However, it is to be appreciated that the slot
204 may be an enclosed slot with openings on one or both ends of the main body portion
202 where the shoe 108 slides into the adapter plate 104.
[0031] The open configuration, shown in Fig. 2, allows for more flexibility in tolerances
between the adapter plate 104 and the shoe 108, and allows for multiple orientations
of the adapter plate 104 when coupled with the other components of the raised toilet
seat assembly 100 of Fig. 1. Furthermore, the width of the slot 204 is designed to
establish an interference fit relation with the shoe 108 when coupled thereto. Accordingly,
the width of the respective portion of the shoe 108 that is to be received in the
slot 204 of the adapter plate 104 may be slightly wider than the width of the slot
204 to establish the interference fit relation between the adapter plate 104 and the
shoe 108.
[0032] In some embodiments, the adapter plate 104 further comprises two end sections 206a
and 206b extending outward from the main body portion 202 and defining associated
passages 208a and 208b, the passages 208a/b each configured to receive a screw, or
similar fastener, typically found on a conventional toilet, such as the toilet 102
of Fig. 1. The configuration of the adapter plate 104 shown in Fig. 2 allows for the
adapter plate 104 to be securely coupled to the toilet 102 via the fasteners, as further
illustrated in Figs. 3A and 3B.
[0033] Referring now to Fig. 3A, the adapter plate 104 may be positioned in a flat orientation
at the rear portion of the toilet 106, and at a toilet seat attachment point, with
the slot 204 facing downward toward the ground, and with each passage 208a and 208b
positioned over holes 302a and 302b on the rear portion of the toilet 106. The rear
portion of the toilet 106 includes the area of the toilet that connects the toilet
bowl to the water tank of the toilet 102. Furthermore, as illustrated in Fig. 3A,
the standard lid of the toilet may be removed permanently, or alternatively, the standard
lid may replaced onto the toilet 102 after coupling the adapter plate 104 to the toilet
102 where it may remain in a lifted position in order to make room for the raised
toilet seat 110. The adapter plate 104 may be oriented with the tips of the end sections
206a/b pointing toward the back (i.e., the water tank) of the toilet 102 as shown
in Fig. 3A, or toward the front of the toilet as shown in Fig. 3B. In either orientation,
the passages 208a/b are to be positioned over the respective holes 302a/b such that
each passage 208a/b may receive, or otherwise fit about, a respective fastener 304a
and 304b, such as a screw. Accordingly, each of the fasteners 304a/b may pass through
the passages 208a/b and into the holes 302a/b where they may be fastened to the toilet
102 in the conventional manner known to a person having ordinary skill in the art.
Alternatively, the adapter plate 104 may be coupled to the toilet 102 by simply sliding
the adapter plate 104 between the standard toilet seat and the toilet bowl when the
standard toilet seat is in a raised position such that the passages 208a/b fit about
the fasteners 304a/b. In this way, the adapter plate 104 may be securely coupled to
the toilet 102 to ensure stability of the raised toilet seat assembly 100 when in
use. The holes 302a/b and the fasteners 304a/b are typically found on a conventional
toilet, and are intended for use in attaching a standard, hinged toilet seat thereto.
[0034] It is to be appreciated that the specific size and shape of the adapter plate 104
is not specific to the present invention, and it may therefore have any suitable shape.
For example, the adapter plate 104 may have a shape other than a predominantly rectangular
shape, as shown in Fig. 2, such as, but not limited to, a triangular, circular, elliptical,
oblong shape, etc. So long as the adapter plate 104 is configured to receive a portion
of the shoe 108 to couple thereto, and is further configured to couple to the toilet
102 in the manner described hereto, the adapter plate 104 may be of any suitable size
and shape to enable this functionality. Additionally, although the adapter plate 104
is shown with two end sections 206a/b and two passages 208a/b, the adapter plate 104
may include a single end section and associated passage, or it may include more than
two passages and associated end sections.
[0035] Referring now to Figs. 4A and 4B, an shoe 108 according to an example embodiment
is shown in further detail, with Fig. 4A showing a perspective view of the shoe 108,
and Fig. 4B showing a side view of the shoe 108. As illustrated, the shoe 108 comprises
a flange member 402, or a first portion, configured to slide into the slot 204 of
the adapter plate 104. The flange member 402 is shown in Fig. 4A to have a rectangular
shape with a v-shaped cutout, but it is to be appreciated that the flange member 402
can be designed to have any suitable shape, such as rectangular, triangular, semicircular,
etc. The flange member 402 is of a thickness such that it may be slid within the slot
204 of the adapter plate 104 when the adapter plate 104 is securely coupled to the
toilet 102, as will be described further with reference to Fig. 5. The flange member
402 further comprises a tapered end 404 (shown in Fig. 4B) toward the end of the flange
member 402. The tapered end 404 facilitates the engagement of the flange member 402
when it is slid into the slot 204 of the adapter plate 104 after the adapter plate
104 has been securely coupled to the toilet 102.
[0036] The shoe 108 further comprises a main body member 406, or a second portion, which
is configured to slide into the rear portion of the raised toilet seat 112 (shown
in Fig. 1) such that the shoe 108 acts as a connection point between the adapter plate
104 and the raised toilet seat 110. The main body member 406 is shown in Fig. 4A to
have an arcuate curved side 408 which allows for a proper mating engagement between
the shoe 108 and the rear portion of the raised toilet seat 112, the rear portion
of the raised toilet seat 112 having the same, or similar, radius of curvature as
that of the arcuate curved side 408.
[0037] Referring now to Fig. 5, the shoe 108 is shown to be coupled to the adapter plate
104. As illustrated in Fig. 5, after the adapter plate 104 has been securely coupled
to the toilet 102 (as described with reference to Figs. 3A and 3B), a space is provided
between the rear portion of the toilet 106 and the adapter plate 104 by virtue of
the slot 204 of the adapter plate 104. Accordingly, the shoe 108 may be slid into
the slot 204 of the adapter plate 104 such that the flange member 402 of the shoe
108 slides within the slot 204 and into the space between the adapter plate 104 and
the rear portion of the toilet 106. In this manner, the shoe 108 is securely coupled
to the adapter plate 104, but is also detachable from the adapter plate 104 by applying
an opposing force to slide the flange member 402 out from within the slot 204 of the
adapter plate 104. Although the coupling between the adapter plate 104 and the shoe
108 is described in example embodiments as being an interference fit relation by sliding
the flange member 402 within the slot 204, it is to be appreciated that other suitable
coupling means comprising two complimentary components may be utilized without changing
the basic characteristics of the system, such as, but not limited to, a tooth and
groove mechanism, dovetail coupling, snaps, a hook-and-loop mechanism such as Velcro®,
etc., or any other detachable coupling known in the art.
[0038] Referring now to Fig. 6, a side view of the raised toilet seat 110 is illustrated.
The raised toilet seat is configured to rest on the toilet bowl of toilet 102 and
comprises a rear portion 112 configured to receive the shoe 108 from the underside
of the raised toilet seat 110, as will be described in more detail with reference
to Figs. 7 and 8. The raised toilet seat 110 further comprises a top surface 602 which
is contoured such that it provides a slightly inclined surface where a portion of
the top surface 602 near the rear portion 112 is raised higher than the remainder
of the top surface 602. The raised toilet seat 110 further comprises a bottom portion
604 that is smaller in diameter relative to the remaining portion of the raised toilet
seat 110 such that the bottom portion 604 is configured to fit within the toilet bowl
of the toilet 102.
[0039] Referring now to Fig. 7, the raised toilet seat assembly 100 is illustrated in its
fully assembled form. As illustrated in Fig. 7, the raised toilet seat 110 may be
coupled to the shoe 108, the details of which will be described in further detail
with reference to Fig. 8. The raised toilet seat 110 is easily detachable from the
shoe 108 by lifting upward on the raised toilet seat 110. While in use, however, the
components of the raised toilet seat assembly 100 are securely coupled in fully assembled
form and thereby provide a stable raised toilet seat assembly 100 for use by patrons.
[0040] Referring now to Fig. 8, the fully assembled raised toilet seat assembly 100 of Fig.
7 is shown from a side elevation view along section line A-A (illustrated in Fig.
7). Section line A-A bisects the toilet 102 and the raised toilet seat assembly 100.
As illustrated in Fig. 8, the adapter plate 104 is coupled to the toilet 102 for example
by tightening the fasteners 304a/b while the adapter plate 104 is positioned flat
on the rear portion of the toilet 106 with the slot 204 facing downward and the passages
208a/b positioned over the holes 302a/b. The shoe 108 is shown to be coupled to the
adapter plate 104 by sliding the flange member 402 into the slot 204 and into the
space between the adapter plate 104 and the rear portion of the toilet 106, as shown
in the zoomed view of Fig. 8. Importantly, Fig. 8 illustrates how the shoe 108 is
coupled to the rear portion of the raised toilet seat 112 by sliding the main body
member 406 of the shoe 108 within a cavity 802, or recess, in the rear portion of
the raised toilet seat 112 which is openly configured and accessible from the underside
of the raised toilet seat 110. By virtue of the arcuate curved side 408 of the shoe
108 shown in Fig. 4A, the shoe 108 securely mates with the raised toilet seat 110
since the rear portion of the raised toilet seat 112 has a curvature at least similar
to that of the arcuate curved side 408 of the shoe 108. In some embodiments, the coupling
between the shoe 108 and the raised toilet seat 110 is by interference fit relation.
