Description




TECHNICAL FIELD




This invention relates to a toilet seat and more particularly to a kit for raising a toilet seat to a higher elevation for use by physically challenged individuals and others who would prefer to use a toilet seat that is elevated from the usual position.




BACKGROUND OF THE INVENTION




The toilet seat for most toilets used in North America is pivotally secured to the upper portion of a porcelain toilet fixture. The upper surface of the porcelain fixture is generally about 14 inches high. The upper surface of the seat is contoured for comfort and is generally about ½ inch to 2 inches above the upper surface of the porcelain fixture. At this height individuals with short stature can use a toilet seat comfortably. Individuals with a relatively tall stature can also use the toilet seats that are about sixteen inches above the floor with minimal discomfort.




Individuals that are physically challenged can find it difficult to sit on any seat that is only about sixteen inches from the floor and to stand up after sitting on such a seat. The current solution to the problem is to replace the porcelain fixture portion of the toilet with a higher porcelain unit. The higher porcelain toilets are relatively expensive and are at best difficult for short people to use.




The employment of porcelain toilet fixtures of different vertical heights is acceptable in public facilities that require multiple toilet fixtures. Such employment is not acceptable in homes. This is particularly true where the need for a toilet with a higher toilet seat is temporary. An adult with a foot, leg or hip injury for example can likely sit and rise to a standing position from a toilet seat that is about eighteen inches high but may have difficulty and possibly require assistance to rise from a toilet seat that is under about sixteen inches high. In general, the higher a seat is the less effort that is required to move off the seat and into a standing position. However, the height of a seat makes it difficult for individuals with short stature to lift themselves up onto the seat. If the height of the seat is raised, more people with short stature will have difficulty lifting themselves up onto the seat.




SUMMARY OF THE INVENTION




An object of the invention is to provide a raised toilet seat on an existing toilet fixture. Another object of the invention is to provide a kit for raising the seat of a toilet for use by individuals that require a higher seat. A further object of the invention is to provide a kit for raising the height of a toilet seat that is removable to lower the toilet seat to a lower position.




Toilet seats are pivotally attached to a seat mounting assembly that permits pivotal movement of the seat about a toilet seat horizontal axis relative to a toilet fixture. The mounting assembly is attached to the porcelain fixture by two bolts that pass through two spaced apart vertical seat mounting passages in the upper rear portion of the toilet fixture. The space between the two vertical passages and the diameter of the two passages in the porcelain toilet fixture is generally the same for most toilet fixtures made in North America.




A toilet seat mounting lift block with the desired height has two spaced apart vertical passages that can be aligned with the seat mounting passages in the toilet fixture. Long bolts pass through apertures in the mounting assembly, passages in the toilet seat mounting lift block, through seat mounting passages in the toilet fixture and are tightened to clamp the seat mounting assembly and the seat mounting lift block to the toilet fixture. A toilet seat support block is secured to a bottom surface of the toilet seat in a position spaced from the toilet seat horizontal axis. The seat support block is preferably secured to the seat by fasteners that permit removal of the seat support block. The seat support block contacts the toilet fixture and holds the toilet seat in a generally horizontal use position when in contact with the toilet fixtures.




After the need for a raised toilet seat ceases, the toilet seat support block is removed from the toilet seat, the toilet seat mounting lift block is removed and the toilet seat is again secured to the toilet fixture in its original lowered position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




The toilet


10


, shown in

FIGS. 1 and 2

includes a porcelain toilet fixture


12


, a water tank


14


, a seat mounting assembly


16


, a seat


18


and a toilet seat cover


20


. The porcelain toilet fixture


12


has a base


22


that is anchored to a floor. A bowl portion


24


, a bowl rim


26


, a water tank support


27


and two space apart vertical seat mounting passages


28


and


30


. The water tank


14


is clamped to the tank support


27


to the rear of the bowl rim


26


.




The seat mounting assembly


16


includes a left bracket


32


that is clamped to the toilet fixture


12


by a bolt


34


that passes through the vertical seat mounting passage


28


and a right bracket


36


that is clamped to the toilet fixture by a bolt


38


that passes through the vertical mounting passage


30


. The left bracket


32


and the right bracket


36


provide a toilet seat horizontal pivot axis


40


.




A toilet seat


18


is pivotally secured to the set a mounting assembly


16


for pivotal movement about the toilet seat horizontal axis


40


. A toilet seat cover


20


is also pivotally secured to the seat mounting assembly


16


for pivotal movement about the toilet seat horizontal axis


40


. However it should be noted that the toilet seat covers


20


are not always used with toilet seats


18


and that the seat covers are optional.




The toilet seat lift kit


42


includes a toilet seat mounting lift block


44


, three toilet seat lift blocks


46


,


47


and


48


and two long bolts


34


and


38


that replace the original short bolts. The toilet seat mounting lift block


44


is a generally rectangular block of a high density rigid plastic material. Two vertical seat mounting passages


54


and


56


pass through the mounting lift block


44


. The seat mounting passages


54


and


56


are spaced apart the same distance as the vertical seat mounting passages


28


and


30


in the toilet fixture


12


. The bottom surface


58


of the seat mounting lift block


44


covers and contacts substantially all of the upwardly facing surface of the toilet fixture


12


between the water tank


14


and the inside of the bowl portion


24


to provide maximum stability for the mounting lift block. The height of the mounting lift block


44


from the bottom surface


58


to the top surface


60


corresponds to the height that the toilet seat


18


is to be raised. The mounting lift block


44


can easily lift the toilet seat


18


from two to four inches.




The two toilet seat lift blocks


46


and


48


are attached to a bottom surface


62


of the toilet seat


18


. One of the lift blocks


46


and


48


is positioned on each side of the toilet seat


18


and well forward of the mounting lift block


44


. The vertical thickness of each of the lift blocks


46


,


47


and


48


is substantially the same as the height of the mounting lift block


44


from the bottom surface


58


to the top surface


60


. By making the mounting lift block


44


and the lift blocks


46


,


47


and


48


the same height, the toilet seat


18


is generally horizontal when the lift blocks


46


,


47


and


48


are setting on top of the bowl rim


26


. The lift blocks


46


,


47


and


48


are preferably attached to the toilet seat


18


by a fastener system that provides quick and easy removal. The fastener system may include mechanical fasteners such as screws, bolts, hook and loop fasteners


63


, or magnetic members. If quick removal is not required, the lift blocks


46


,


47


and


48


can be glued to the toilet seat


18


. The number, size and shape of the lift blocks


46


,


47


and


48


can be modified.




Toilet seat lift kits


42


are installed by removing the short bolts and removing the seat mounting assembly


16


together with the seat


18


and the seat cover


20


from the toilet fixture


12


. Long bolts


34


and


38


then replace the short bolts, pass through the seating mounting assembly


16


, pass through the seat mounting passages


54


and


56


through the mounting lift block


44


and through the vertical seat mounting passages


28


and


30


in the fixture


12


. A nut


35


is received on each bolt


34


and


38


under the bowl rim


26


and behind the bowl portion


24


. Bolts


34


and


38


are then tightened to secure the toilet seat


18


in place.




The lift blocks


46


,


47


and


48


are secured to the seat


18


as disclosed above and the toilet


10


is ready for use with the seat in a raised horizontal position.




The mounting lift block


44


and the lift blocks


46


,


47


and


48


as shown in the drawing figures are molded hollow plastic members with reinforcing ribs


70


and


72


. The mounting lift block


44


and the lift blocks


46


,


47


and


48


could also be solid plastic members. Hollow molded blocks weigh substantially less than solid plastic blocks. Three lift blocks


46


,


47


and


48


provide adequate support for the seat


18


. However, the number of lift blocks


46


,


47


and


48


can be changed if desired. The front center lift block


47


also functions as a spray guard. Recesses


74


in the top of the lift blocks


46


,


47


and


48


straddle seat support pads on the bottom surface


62


of the toilet seat


18


if such pads are employed on the seat. It may be necessary to increase the vertical height of the lift blocks


46


,


47


and


48


by the height of straddled seat support pads to keep the toilet seat


18


horizontal.




The vertical height of the seat mounting lift block


44


and the seat lift blocks


46


,


47


and


48


is preferably two inches. However, the height can be varied. The seat mounting lift block


44


provides stability for the toilet seat


18


and can accommodate a range of vertical heights.




Obviously, many modifications and variation of the present invention are possible in light of the above teachings. It is, therefore, to be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described. The invention is defined by the claims.
