FIGS. 1 and 2 illustrate an elevated toilet seat assembly 10 coupled to a toilet 15. The toilet seat assembly 10 includes a toilet seat 20 pivotably coupled to a hinge post 25 about an axis 30 between a first position (FIG. 1) and a second position (FIG. 2). The first position is a raised or upright position. The second position is a lowered or in-use position when the toilet seat 20 engages a rim surface 32 of the toilet 15. The hinge post 25 includes two post members 35 that are coupled to a base 40 of the toilet 15. The hinge post 25 can be fixed to the base 40 by fasteners or selectively coupled to the base 40 by a quick-disconnect feature. In other embodiments, the hinge post 25 can include one post member coupling the toilet seat 20 to the base 40. In the illustrated embodiment, a height 45 of the hinge post 25 (i.e., a distance between the axis 30 and a bottom surface 50 of the hinge post 25; FIG. 4) is between about 3 inches and about 5 inches. In some embodiments, the height 45 of the hinge post 25 is about 4 inches.

The illustrated toilet seat 20 is made of plastic. More particularly, the toilet seat 20 is injection molded as a single piece of solid plastic. As such, the below described features of the toilet seat 20 are formed in one injection molding process. With reference to FIGS. 3 and 4, the toilet seat 20 includes an upper portion 55 having a support surface 60 defined between an outer perimeter 65 and an inner perimeter 70 of the upper portion 55. The inner perimeter 70 is an inner seat edge of the upper portion 55 and defines a central or top opening 75 of the toilet seat 20. As best shown in FIG. 4, the upper portion 55 defines a maximum thickness 80 (e.g., a maximum height of the upper portion 55) between about 0.35 inches and about 0.85 inches. The maximum thickness 80 is measured from the support surface 60 to a bottom surface 85 of the upper portion 55. In other embodiments, the maximum thickness 80 of the upper portion 55 is about 0.6 inches. Furthermore, the upper portion 55 includes a protrusion 90 to couple with the hinge post 25 (FIGS. 4 and 5).

The toilet seat 20 also includes a lower portion 95 extending from the bottom surface 85 of the upper portion 55 (FIG. 4). The lower portion 95 includes a shield or guard 100 having an upper edge 105 (FIGS. 3 and 5) defined by the inner perimeter 70 of the upper portion 55, a lower edge or inner guard edge 110 opposite the upper edge 105 defining a bottom opening 106 of the toilet seat 20, and an inner surface 115 and an outer surface 120 extending between the upper edge 105 and the lower edge 110. The guard 100 defines a height 125 of about 2.12 inches to about 2.62 inches. In other embodiments, the height 125 is about 2.375 inches. The height 125 is measured from the upper edge 105 to the lower edge 110 of the guard 100. As such, a ratio of the height 125 over the maximum thickness 80 of the upper portion 55 is between about 3 and about 6. In other embodiments, the ratio of the height 125 over the maximum thickness 80 of the upper portion 55 is about 4. The illustrated guard 100 tapers from the lower edge 110 to the upper edge 105. With reference to FIG. 4, the guard 100 includes a nonlinear taper (e.g., a curved taper) that gradually and continuously tapers from the lower edge 110 to the upper edge 105. In other embodiments, the guard 100 can include a linear taper. In further embodiments, the guard 100 can be a stepped taper and/or include portions without any taper and other portions with angled tapers. In yet further embodiments, the guard 100 can include a discontinuous taper from the lower edge 110 to the upper edge 105. In addition, the illustrated guard 100 continuously and completely surrounds the central opening 75 of the upper portion 55 (FIG. 5), and the guard 100 does not extend outwardly beyond the outer perimeter 65 of the upper portion 55 (FIGS. 4 and 5). For example, the lower edge 110 is positioned between the outer perimeter 65 and the inner perimeter 70 of the upper portion 55 as shown in FIG. 5.

With continued reference to FIG. 5, a longitudinal plane 130 (e.g., a first plane) is oriented perpendicular to the axis 30 and extends through the top opening 75 and the bottom opening 106 of the toilet seat 20. As such, the longitudinal plane 130 is also oriented perpendicular to the rim surface 32 of the toilet 15 and extends through the top opening 75 and the bottom opening 106 when the toilet seat 20 is in the in-use position. FIG. 5 shows one position of the longitudinal plane 130 (e.g., extending centrally through the top and bottom openings 75, 160), but the longitudinal plane 130 can also be positioned differently (e.g., right or left of the longitudinal plane 130 as illustrated in FIG. 5) as long as the longitudinal plane 130 is oriented perpendicular to the axis 30. With continued reference to FIG. 5, a first distance 135, which is measured within the longitudinal plane 130 between opposing points 140 on the upper edge 105, is less than a second distance 145, which is measured within the longitudinal plane 130 between opposing points 150 on the lower edge 110.

The guard 100 also includes a lateral plane 155 (e.g., a second plane; FIG. 5) oriented parallel to the axis 30 and oriented perpendicular to the rim surface 32 of the toilet 15 when the toilet seat 20 is in the in-use position. The lateral plane 155 also extends through the top opening 75 and the bottom opening 106. FIG. 5 shows one position of the lateral plane 155 (e.g., extending centrally through the top and bottom openings 75, 160), but the lateral plane 155 can also be positioned differently (e.g., above or below the lateral plane 155 as illustrated in FIG. 5) as long as the lateral plane 155 is oriented parallel to the axis 30 and perpendicular to the rim surface 32 when the toilet seat 20 is in the in-use position. With continued reference to FIG. 5, a third distance 160, which is measured within the lateral plane 155 between opposing points 165 on the upper edge 105, is less than a fourth distance 170, which is measured within the lateral plane 155 between opposing points 175 on the lower edge 110. Stated another way, a maximum dimension of the upper edge 105 of the support surface 60 (e.g., a distance separating points 140) is less than a maximum dimension of the lower edge 110 of the guard 100 (e.g., a distance separating points 150). As such, in one embodiment, the maximum dimension of the upper edge 105 and the lower edge 110 can be measured perpendicular to the axis 30. In other embodiments, the maximum dimension of the upper edge 105 and the lower edge 110 can be measured parallel to the axis 30 such that the maximum dimension of the upper edge 105 (e.g., a distance separating points 165) is less than the maximum dimension of the lower edge 110 (e.g., a distance separating points 175).

With reference to FIG. 5, a plurality of supports 180 extend outwardly from the outer surface 120 of the guard 100 toward the outer perimeter 65 of the upper portion 55. In other words, each support 180 extends from the outer surface 120 of the guard 100 substantially parallel to the axis 30. In the illustrated embodiment, each support 180 extends along the entire height 125 of the guard 100 from the bottom surface 85 of the upper portion 55 to the lower edge 110 of the guard 100 (FIG. 4). For example, the height 125 of the guard 100 is generally the same height of the supports 180, which is greater than the maximum thickness 80 of the upper portion 55. In other embodiments, at least one support 180 can extend a portion of the height 125 of the guard 100 (e.g., from a midway of the guard 100 to the lower edge 110). The supports 180 are formed within the foot print area of the upper portion 55 (i.e., the supports 180 do not extend outwardly beyond the outer perimeter 65 of the support surface 60). The illustrated supports 180 include two pairs of supports, with each pair positioned on opposite sides of the guard 100 and extending away from each other (FIG. 5). In other embodiments, the supports 180 can include more or less than four supports and/or be arranged differently around the guard 100. For example, the toilet seat 20 can include at least one support 180 that extends away/toward the protrusion 90 (extending transverse (e.g., non-parallel) to the axis 30). In the illustrated embodiment, each support 180 includes a foot 185 positioned on one end of the support 180. Each foot 185 extends below the lower edge 110 of the guard 100 (FIG. 4). In other embodiments, each foot 185 can be a separate member (e.g., a rubber foot) from the toilet seat 20 that can be coupled to the end of each support 180. In such embodiments, the feet 185 provide a softer contact surface that reduces the possibility of marring or noisily engaging the toilet 15 during use.

As shown in FIGS. 3-5, the toilet seat assembly 10 also includes two support handles or arms 190 for a person to stabilize themselves sitting down on the toilet seat 20, during use of the toilet seat 20, and/or standing up from the toilet seat 20. In particular, each arm 190 is tubular in construction and is fixed to a pair of supports 180. In other embodiments, the arms 190 can be removably coupled to the toilet seat 20. In some embodiments, the support handles 190 can be plastic injection molded with the toilet seat 20 as one component. In further embodiments, the toilet seat assembly 10 can omit the support handles 190.

The illustrated toilet seat assembly 10 also includes a lid 195 that is pivotably coupled to the hinge posts 25 and the protrusion 90 about the axis 30 to selectively cover the central opening 75 of the toilet seat 20.

As the toilet seat 20 is moved from the upright position (FIG. 1) to the in-use position (FIG. 2), the feet 185 of the supports 180 engage the rim surface 32 of the toilet 15 to support the toilet seat 20 at an elevated height above the rim surface 32. Accordingly, the bottom surface 85 of the upper portion 55 is positioned away from the rim surface 32 of the toilet 15 (e.g., the bottom surface 85 does not engage the rim surface 32). In the illustrated embodiment, the support surface 60 of the toilet seat 20 is positioned between about 3 inches and about 5 inches above the rim surface 32 once the toilet seat 20 is in the in-use position. Accordingly, the elevated height of the support surface 60 assists in helping a person sit down on the support surface 60 or stand up from the support surface 60 before/after use. Furthermore, the guard 100 is operable to block waste from splashing out of the toilet 15 during use.

As best shown in FIG. 4, as the feet 185 extend beyond the lower edge 110 of the guard 100 to engage the rim surface 32 of the toilet 15, the lower edge 110 is positioned above the rim surface 32 (e.g., the lower edge 110 does not extend below the rim surface 32 into the toilet 15). In other embodiments, the feet 185 can be omitted so that the lower edge 110 of the guard 100 is positioned substantially level with the rim surface 32 when the supports 180 engage the rim surface 32. Because the guard 100 does not extend into the toilet 15, the toilet seat 20 is operably universal with many different types of toilets 15 (e.g., U.S. style round toilets, U.S. style elongated toilets, European style toilets, etc.).
