Raised superimposed toilet seat and securing clamp

A raised toilet seat is superimposed upon the bowl of a conventional toilet. A clamp has a section which fits into a space provided when the lid and the seat of the conventional toilet are lifted, and has another section which fits around the back end of the raised superimposed toilet seat and engages the underside thereof, whereby the raised superimposed toilet seat is secured to the conventional toilet.

BACKGROUND OF THE INVENTION 
Raised toilet seats which are superimposed upon conventional toilets are an 
indispensable aid for invalids and others who experience difficulty in 
sitting on and raising from a conventional toilet seat. The raised 
superimposed toilet seat is disposed directly on the bowl of the 
conventional toilet and affords complete comfort to the user as is 
desired. Toilet seats of the type contemplated are described, for example, 
in U.S. Pat. Nos. Des. D237,887 and D242,457 issued to Kurt Landsberger on 
Dec. 2, 1975 and Nov. 23, 1976, respectively. 
Prior to the present invention these seats have been used with conventional 
toilets as aforenoted without any clamping device to securely mount the 
seats to the conventional toilets. While this arrangement is sufficient in 
many situations, it is often required, to accommodate the capabilities of 
the user, to clamp the raised superimposed seat to the conventional toilet 
to secure the seat thereto and to otherwise provide a degree of stability 
to the seat when it is being used. The present invention accommodates this 
requirement in a simple yet satisfactory manner. 
Accordingly, it is an object of the present invention to provide a raised 
toilet seat of the type which is superimposed upon a conventional toilet 
in combination with a clamp for securing the raised superimposed toilet 
seat to the conventional toilet. 
SUMMARY OF THE INVENTION 
A raised toilet seat is superimposed upon the bowl of a conventional 
toilet, with the lid and seat of the conventional toilet in a lifted 
position, whereby a space is provided between the lifted seat and lid and 
the section of the toilet connecting the bowl and water tank to the 
toilet. A clamp is arranged to fit into the space so as to be retained 
therein, and to curve around the back of the raised superimposed toilet 
seat to terminate adjacent the underside of the seat. The underside of the 
seat has a recess therein which receives a pin-like protrusion on the 
adjacent clamp. The cooperative action of the clamp with the raised 
superimposed seat is effective for securing said seat to the conventional 
toilet.

DETAILED DESCRIPTION OF THE INVENTION 
With reference to FIGS. 1, 2 and 3 a clamp is designated generally by the 
numeral 2. Clamp 2 has an L-shaped member 4 and an L-shaped member 6. 
L-shaped members 4 and 6 are in spaced relation each to the other, and are 
joined by a contoured member 8. L-shaped members 4 and 6 and contoured 
member 8 form an integral clamp 2. 
The arrangement is such that L-shaped members 4 and 6 extend substantially 
parallel to each other. L-shaped member 4 is shorter than L-shaped member 
6 so that the base 4A of L-shaped member 4 is above the base 6A of 
L-shaped member 6. Base 6A has a pin-like member 10 centrally disposed 
near the end thereof and extending normal from the base as will be readily 
seen from FIGS. 1, 2 and 3. 
L-shaped member 4 including its base 4A are relatively wide, while L-shaped 
member 6 including its base 6A are relatively narrow as will be readily 
seen from FIGS. 2 and 3. Base 6A extends in the same direction as base 4A, 
but not beyond the beginning of L-shaped member 4. 
With reference now to FIGS. 4 and 5, a conventional toilet is designated by 
the numeral 12 and has a bowl 14, a water tank 16, and a connecting 
section 18 which connects bowl 14 and tank 16. A seat 20 and a lid 22 are 
suitably coupled to connecting member 18 as by a hinge arrangement 19 or 
the like (symbolically shown) so as to be lowered and lifted relative to 
toilet bowl 14. When seat 20 and lid 22 are in the lifted position, that 
is resting against tank 16 as shown in FIG. 4, a space 24 is provided 
between hinge arrangement 19 and connecting section 18. This space is used 
in association with clamp 12 so as to firmly secure a raised toilet seat 
26 in a superimposed position on toilet bowl 14 as will next be described. 
Only as much of conventional toilet 12 is shown and described as is 
necessary to understand the present invention. 
Raised toilet seat 26 may be of various configurations such as described in 
the aforenoted U.S. Pat. Nos. Des. D237,887 and D242,457 and is shown in 
FIGS. 4 and 5 in its simplist form for purposes of describing the 
invention. It will suffice to say for present purposes that the top 28 of 
raised toilet seat 26 is suitably contoured and rests on bowl 14, and has 
a through opening 30 disposed substantially central to seat 26 as best 
shown in FIG. 5. 
Toilet seat 26 has a lower portion 32 (FIG. 4) which is smaller in diameter 
than the top of the seat so as to fit within toilet bowl 14. In modifying 
seat 26 for the purposes of the invention the underside of lower seat 
portion 32 carries a recess 34 for receiving pin-like member 10 of base 
portion 6A of L-shaped member 6 as will hereinafter be more specifically 
described. 
Raised seat 26 is superimposed upon bowl 14, with lower portion 32 of the 
seat resting within the bowl as shown in FIG. 4. Clamp 2 is oriented so 
that base 4A of L-shaped member 4 is substantially horizontal as is base 
6A of L-shaped member 6. 
With the clamp thus oriented, base 4A of L-shaped member 4 is disposed 
within space 24 between hinge arrangement 19 and connecting member 18 so 
as to be captured in said space. 
L-shaped portion 4 of clamp 2 extends upwardly adjacent the rear exterior 
portion of raised seat 26, with contoured member 8 of clamp 2 curving 
around and adjacent the rear top portion of raised seat 26 so that 
L-shaped member 6 extends downwardly within opening 30 adjacent the 
interior of the rear portion as shown in FIGS. 4 and 5. L-shaped member 6 
is sized so as to extend below lower portion 32, with base 6A adjacent the 
underside thereof, so that pin-like member 10 engages recess 34. 
With the arrangement shown--i.e., base 4A of L-shaped portion 4 of clamp 2 
captured in space 24, pin-like member 10 on base 6A of L-shaped portion 6 
engaging recess 24 and contoured member 8 curving around the top of seat 
26, it will be seen that seat 26, superimposed upon toilet 12 is firmly 
secured thereto so as to preclude movement thereof as might otherwise 
occur upon a user lowering or lifting the body relative to the raised 
seat. 
Clamp 2 may be molded of a smooth, easily cleaned strong polyethylene 
material so as to conform to the material of seat 26, and to thereby 
provide little encumberance to the user. 
It will thus be seen from the aforegoing description of the invention that 
a raised superimposed toilet seat and securing clamp have been provided in 
combination, whereby when the raised seat is superimposed upon the bowl of 
a conventional toilet and the seat and the lid of the conventional toilet 
are in a raised position against the water tank of the toilet, the clamp 
is in cooperative relation with the raised superimposed seat so as to 
firmly secure said seat in a superimposed position to the conventional 
toilet. 
The arrangement described maximizes user comfort and stability and thus 
enhances the use of raised superimposed toilet seats by elderly persons 
and others who suffer immobilizing infirmaties to the extent that they are 
unable to use conventional toilet seats. 
With the aforegoing description of the invention in mind reference is had 
to the appended claims for the scope of the invention.
