Definitions
- the present invention relates to toilet seats.
- it relates to an improved elevated hinged toilet seat of simple manufacture and ease of installation.
- Cope U.S. Pat. No. 1,164,927, issued Dec. 21, 1915, is directed to a stamped metal closet seat with a concave bottom and corresponding convex top seat surface (Col 1, lines 54-56 embossed to extend oppositely from their meeting plane).
- This Cope concave undersurface creates a hollow, which if not supported allows the lip edges of the seat to pass below the ridge of the toilet bowl.
- the Cope concave undersurface was therefore associated with lugs to elevate the bottom lip of the seat proximate the rim of the toilet bowl as shown in FIGS. 1 and 2 .
- lugs therefore do not elevate the top surface of the toilet seat in excess of approximately 2 inches above the toilet rim, but are approximately even with it as the Cope toilet seat undersurface has an interior lip, which extends slightly below the rim of the toilet bowl as shown in FIG. 2 .
- To elevate Cope to the height of applicant's invention described below would require the lugs to be of an additional length of the cross-sectional thickness of the solid seat. This would result in lugs of a height which makes the mounted seat unstable, causing it to slide off the toilet bowl during use with possible injury to the user.
- Cope concave undersurface associated with lugs is difficult to clean, presenting a sanitation problem.
- Cope hinges with cast metal screws are unsightly and would place too much strain on the vitreous toilet bowl making it subject to braking.
- the Cope stamped sheet metal seat would also not be strong enough to support portly users, making it likely to bend. If made of cast metal to prevent bending, the cost and weight would be prohibitive. Nor is the Cope metal seat comfortable as it is cold to the touch.
- Plonta U.S. Pat. No. 6,418,566 issued Jul. 16, 2002 discloses a toilet seat lift kit method for elevating conventional toilet seats with lift blocks, which are attached to the bottom of the toilet seat.
- Toilet seats are generally made from one of two materials.
- Plastic toilet seats are made from a type of thermoplastic called polystyrene.
- the less expensive and more common type of toilet seat is made from a blend of wood and plastic.
- the wood is hardwood, usually maple or birch, which has been ground up into the consistency of flour. This wood flour is blended with a powdered plastic resin called melamine.
- Zinc stearate is a third ingredient in wooden toilet seats. This prevents the wood-resin mix from sticking to the mold in the manufacturing process.
- the Plonta kits require fasteners to affix the lift blocks to the toilet seat bottom surface, which may wobble or have difficulty being secured to the undersides of toilet seats.
- Toilet bowl rims are smooth and slightly convex and are about 1 inch to 1.5 inches wide.
- the Plonta kit blocks would very likely slide off the bowl rims.
- an adhesive or screws, or both, to secure them to the underside of the toilet seat is impractical.
- the toilet seat is generally a half to three quarters of an inch thick, which is too thin for screws, especially for the blend of wood and plastic seats. If screwed into the plastic seats, the seats are too brittle to provide a good hold.
- U.S. Pat. No. 5,251,338 issued Oct. 12, 1993 discloses a toilet height conversion apparatus including a mounting block and a pivotally-connected raisable elevator onto which a conventional toilet seat is attached. It employs a double hinged seat and elevator construction, which is affixed to a conventional toilet rim.
- Bemis U.S. Pat. No. 4,213,211 issued Jul. 22, 1980 discloses another toilet seat elevator device including a mounting block and a pivotally-connected raisable elevator onto which a conventional toilet seat is attached. It also employs a double hinged seat and elevator construction, which is affixed to a conventional toilet bowl rim.
- Cited for general interest is Francke, U.S. Pat. No. 5,191,660 issued Mar. 9, 1993 disclosing a device for attaching a toilet elevator to the bowl of a toilet.
- Newcomer, U.S. Pat. No. 3,301,121, issued Jan. 31, 1967 discloses an anti-wobble hinge assembly for securing a toilet seat to a toilet bowl rim.
- None of the above references provides a hinged elevated toilet seat of simple construction with lid that can be attached to the toilet bowl rim without modification, and in the conventional manner, by the user to provide a secure seat.
- the present invention comprises a hinged raised toilet seat for a toilet bowl having a rim surrounding its opening that can be attached to the rim.
- the toilet seat is sized to fit onto the rim of a toilet bowl and has a top with rounded edges associated with a flat planar bottom to form an elevated seat surface of solid cross section defining a center hole.
- the thickness of the toilet seat is dependent on the strength of the material from which it is constructed, with reinforcement internal structure required for materials, which lack tensile strength to support a user.
- the toilet seat has a plurality of spaced around pedestals formed into its flat planar bottom, which contact the rim of the toilet bowl and raise the toilet seat approximately two or more inches, when mounted, to make it easier for a user sitting down and getting up.
- the number of pedestals is dependent upon the tensile strength and length of the toilet. The number required is reduced as the tensile strength of the toilet seat increases. Conversely, the number increases as the length of the toilet seat increases. For example, for solid plastic single piece construction, usually only two pedestals at the front of the toilet seat are required to hold the weight of a typical user. Two front pedestals are also only required for particle board seats with internal linear steel reinforcement structure. However, for longer toilet seat models or for heavy duty use, additional pedestals are symmetrically spaced around the flat planar bottom. The ends of the pedestals have rubber cushions on their bottoms to contact the rim of the toilet bowl and prevent slippage when in use.
- the height of the pedestals varies, but is usually in excess of two inches, and typically is approximately three inches in height. However, the exact height is sized to provide an elevated height sufficient to make it easier for a user to sit down on and get up from the toilet seat. The exact height is also dependent on the weight of a user, as the higher the pedestal, the more it may wobble when used by a heavy user, necessitating lower pedestals or an increased number of pedestals to more uniformly distribute the user's weight along the rim of the toilet. (We may need this language to support a formula resizing the pedestals in the claims).
- the pedestals and toilet seat are of unitary construction.
- a single piece toilet seat with pedestals provides a rigid construction, which will not come apart during use and is easy to clean.
- Single piece construction is also quicker to install, and avoids problems with shipping missing parts, or misplacement of parts during assembly.
- the toilet seat is hingedly attached to the toilet bowl with an elevated hinge adapted to accommodate the lowered toilet seat to allow the seat to lie parallel to the rim of the bowl. It also has a lid also hingedly attached, which can be raised for use of the toilet seat.
- the toilet seat is injection molded out of nylon or plastic with eight at least 2 inch high pedestals molded as integral parts of the seat.
- the toilet seat is injection molded out of nylon or plastic with two approximately three inch high pedestals affixed to the front of the toilet seat opposite the hinges.
- the toilet seat is constructed out of composite wood and plastic embedded with internal steel reinforcement structure to provide sufficient tensile strength to minimize the number of pedestals required to spread the weight load of a user.
- the hinged raised seat is used in the similar manner of a conventional toilet seat.
- the hinge connecting the lid and toilet seat is first affixed to the toilet bowl top via conventional fasteners. Then the hinged toilet seat and lid are either raised or lowered.
- the attached drawings and specification description provides more details of the device particularly adapted for use by the elderly.
- the present invention is therefore particularly adapted to provide for the needs of the elderly who have trouble rising from a conventional toilet seat. It is inexpensive to make, is readily cleaned, and can be installed without special tools to raise the toilet seat height when attached to a conventional toilet bowl.

Abstract
An improved elevated hinged toilet seat with lid of simple construction and ease of installation.
Description
- This application is a continuation-in-part application of the U.S. patent application entitled “Elevated Toilet Seat”, filed May 25, 2007 and assigned Ser. No. 11/807,052; which is a continuation-in-part application of the provisional patent application entitled “Elevated Toilet Seat”, filed Aug. 14, 2006 and assigned Ser. No. 60/837,134.
- 1. Field of Invention
- The present invention relates to toilet seats. In particular, it relates to an improved elevated hinged toilet seat of simple manufacture and ease of installation.
- 2. Description of Related Art
- Various toilet seats are known in the art. Cope, U.S. Pat. No. 1,164,927, issued Dec. 21, 1915, is directed to a stamped metal closet seat with a concave bottom and corresponding convex top seat surface (Col 1, lines 54-56 embossed to extend oppositely from their meeting plane). This Cope concave undersurface creates a hollow, which if not supported allows the lip edges of the seat to pass below the ridge of the toilet bowl. The Cope concave undersurface was therefore associated with lugs to elevate the bottom lip of the seat proximate the rim of the toilet bowl as shown in
FIGS. 1 and 2 . These lugs therefore do not elevate the top surface of the toilet seat in excess of approximately 2 inches above the toilet rim, but are approximately even with it as the Cope toilet seat undersurface has an interior lip, which extends slightly below the rim of the toilet bowl as shown inFIG. 2 . To elevate Cope to the height of applicant's invention described below would require the lugs to be of an additional length of the cross-sectional thickness of the solid seat. This would result in lugs of a height which makes the mounted seat unstable, causing it to slide off the toilet bowl during use with possible injury to the user. - Further, the Cope concave undersurface associated with lugs is difficult to clean, presenting a sanitation problem. In addition, the Cope hinges with cast metal screws are unsightly and would place too much strain on the vitreous toilet bowl making it subject to braking. The Cope stamped sheet metal seat would also not be strong enough to support portly users, making it likely to bend. If made of cast metal to prevent bending, the cost and weight would be prohibitive. Nor is the Cope metal seat comfortable as it is cold to the touch.
- Steadman, U.S. Pat. No. 2,050,472 issued Aug. 11, 1936 discloses another stamped sheet metal seat with cover of similar design as Cope. It therefore suffers from the same deficiencies discussed above.
- Plonta, U.S. Pat. No. 6,418,566 issued Jul. 16, 2002 discloses a toilet seat lift kit method for elevating conventional toilet seats with lift blocks, which are attached to the bottom of the toilet seat. Toilet seats are generally made from one of two materials. Plastic toilet seats are made from a type of thermoplastic called polystyrene. The less expensive and more common type of toilet seat is made from a blend of wood and plastic. The wood is hardwood, usually maple or birch, which has been ground up into the consistency of flour. This wood flour is blended with a powdered plastic resin called melamine. Zinc stearate is a third ingredient in wooden toilet seats. This prevents the wood-resin mix from sticking to the mold in the manufacturing process.
- Consequently, the Plonta kits require fasteners to affix the lift blocks to the toilet seat bottom surface, which may wobble or have difficulty being secured to the undersides of toilet seats. Toilet bowl rims are smooth and slightly convex and are about 1 inch to 1.5 inches wide. The Plonta kit blocks would very likely slide off the bowl rims. In addition relying on an adhesive or screws, or both, to secure them to the underside of the toilet seat is impractical. The toilet seat is generally a half to three quarters of an inch thick, which is too thin for screws, especially for the blend of wood and plastic seats. If screwed into the plastic seats, the seats are too brittle to provide a good hold.
- They also are generally positioned toward the front and/or rear of the toilet seat, subjecting the toilet seat to extreme tensile breaking stress; particularly with the composite wood and plastic seats, which have no internal seat reinforcement structure. As elderly users are now heavier and heavier, the likelihood of injury from toilet seat breakage is present when the Plonta kit places front and real block mounting on the composite wood and plastic conventional seat.
- Thom et al, U.S. Pat. No. 6,042,838 issued Apr. 25, 2000 provides a toilet seat with raised hand arms to assist the infirm in rising there from. Ellis, U.S. Pat. No. 5,708,989 issued Jan. 20, 1998 discloses another toilet seat with raised barrel back arms to assist the infirm in rising there from. Both are designed for insertion into to hold onto the bowl of conventional toilets.
- Jackson, U.S. Des. No. 390,931 issued Feb. 17, 1998 discloses an insertable raised toilet seat designed for insertion into and hold onto the bowl of conventional toilets. Hunt, U.S. Des. No. 489,438 issued May 4, 2004 discloses another insertable raised toilet seat designed for insertion into and hold onto the bowl of conventional toilets.
- Harrison, U.S. Des. No. 291,348 issued Aug. 11, 1987 discloses a hinged elevated toilet seat with no lid.
- Light, U.S. Pat. No. 5,251,338 issued Oct. 12, 1993 discloses a toilet height conversion apparatus including a mounting block and a pivotally-connected raisable elevator onto which a conventional toilet seat is attached. It employs a double hinged seat and elevator construction, which is affixed to a conventional toilet rim. Bemis, U.S. Pat. No. 4,213,211 issued Jul. 22, 1980 discloses another toilet seat elevator device including a mounting block and a pivotally-connected raisable elevator onto which a conventional toilet seat is attached. It also employs a double hinged seat and elevator construction, which is affixed to a conventional toilet bowl rim. Locarno, U.S. Pat. No. 5,199,112 issued Apr. 6, 1993 discloses a raised superimposed toilet seat particularly of use for total hip arthroplasty patients. Locarno, U.S. Pat. No. 5,027,445 issued Jul. 2, 1991 discloses another raised superimposed toilet seat with a securing clamp. Smith et al, U.S. Pat. No. 4,517,689 issued May 21, 1985 discloses a toilet seat usable for both handicapped and nonhandicapped users selectively raising either a conventional toilet seat or an elevated toilet seat, both hingedly attached to a toilet bowl rim.
- Cited for general interest is Francke, U.S. Pat. No. 5,191,660 issued Mar. 9, 1993 disclosing a device for attaching a toilet elevator to the bowl of a toilet. Newcomer, U.S. Pat. No. 3,301,121, issued Jan. 31, 1967 discloses an anti-wobble hinge assembly for securing a toilet seat to a toilet bowl rim.
- None of the above references provides a hinged elevated toilet seat of simple construction with lid that can be attached to the toilet bowl rim without modification, and in the conventional manner, by the user to provide a secure seat.
- The present invention comprises a hinged raised toilet seat for a toilet bowl having a rim surrounding its opening that can be attached to the rim. The toilet seat is sized to fit onto the rim of a toilet bowl and has a top with rounded edges associated with a flat planar bottom to form an elevated seat surface of solid cross section defining a center hole. The thickness of the toilet seat is dependent on the strength of the material from which it is constructed, with reinforcement internal structure required for materials, which lack tensile strength to support a user.
- The toilet seat has a plurality of spaced around pedestals formed into its flat planar bottom, which contact the rim of the toilet bowl and raise the toilet seat approximately two or more inches, when mounted, to make it easier for a user sitting down and getting up. The number of pedestals is dependent upon the tensile strength and length of the toilet. The number required is reduced as the tensile strength of the toilet seat increases. Conversely, the number increases as the length of the toilet seat increases. For example, for solid plastic single piece construction, usually only two pedestals at the front of the toilet seat are required to hold the weight of a typical user. Two front pedestals are also only required for particle board seats with internal linear steel reinforcement structure. However, for longer toilet seat models or for heavy duty use, additional pedestals are symmetrically spaced around the flat planar bottom.

Single piece construction is also quicker to install, and avoids problems with shipping missing parts, or misplacement of parts during assembly.
- The toilet seat is hingedly attached to the toilet bowl with an elevated hinge adapted to accommodate the lowered toilet seat to allow the seat to lie parallel to the rim of the bowl. It also has a lid also hingedly attached, which can be raised for use of the toilet seat. In one preferred embodiment for heavy duty use, the toilet seat is injection molded out of nylon or plastic with eight at least 2 inch high pedestals molded as integral parts of the seat.
- In another preferred embodiment for use with standard users, the toilet seat is injection molded out of nylon or plastic with two approximately three inch high pedestals affixed to the front of the toilet seat opposite the hinges.
- In still another preferred embodiment, the toilet seat is constructed out of composite wood and plastic embedded with internal steel reinforcement structure to provide sufficient tensile strength to minimize the number of pedestals required to spread the weight load of a user.
- The hinged raised seat is used in the similar manner of a conventional toilet seat. The hinge connecting the lid and toilet seat is first affixed to the toilet bowl top via conventional fasteners. Then the hinged toilet seat and lid are either raised or lowered. The attached drawings and specification description provides more details of the device particularly adapted for use by the elderly.
- The present invention is therefore particularly adapted to provide for the needs of the elderly who have trouble rising from a conventional toilet seat. It is inexpensive to make, is readily cleaned, and can be installed without special tools to raise the toilet seat height when attached to a conventional toilet bowl.
