Description
BACKGROUND OF THE INVENTION
The present invention relates generally to waste disposal
apparatus, and more particularly to an occupant seat structure for
toilet bowls.
Toilet bowls as conventionally arranged are provided with a
low-level hinged seat or ring which presents a very real and vital
personal problem in many instances, particularly in the case of
elderly people, and others who encounter inconvenience and painful
distress when required to sit at the usual low-level, but find
comfort and relief from pain and its attending uncomfortable
circumstances, when sitting at a higher or elevated level. A
problem also exists in cases where persons confined to a wheel
chair are required to transfer from the chair to the seat of a
low-level conventional toilet bowl arrangement. By utilizing the
high level arrangement which is made possible in the present
invention, change of position from the wheel chair to the seat of
the toilet bowl, and vice versa, is materially aided.
Various structures have been suggested heretofore for coping with
the above mentioned problem, but in the main these suggested
arrangements have only partially been successful, and in most cases
have involved structures of a rather complicated nature, and have
involved the use of components which were not readily adaptable for
use in a low-level arrangement, and which could later by the
addition of readily available components be reassembled to provide
a high-level or elevated seat arrangement, when such need should
later arise.
I has been previously known, for example, in U.S. Letters Pat. No.
3,364,505 to provide a seat which is mounted at the top of a
compensating riser or adapter in which an elevating hollow skirt is
interposed between the seat and a supporting surface on the toilet
bowl. The seat and riser or elevator provide a self-contained
applicable and removable bowl attachment for use in lieu of the
customary lid-equipped hingedly attached occupant seat. The seat
portion of the device of the patent is fixedly positioned and
cannot be hingedly raised or lowered, and does not provide the
usual lid or cover. That is to say that the device of the patent
does not provide a complete seat or cover arrangement in the
raised-level position which is compatible with the usual low-level
installation. Moreover, the seat portion of the patent device lacks
the side handles of the present invention which provide hand grips
for the person while transferring to and from the seat or while
seated thereon.
In the present invention, the seat structure embodies a novel
annular seat with side hand grips which can be mounted in the usual
position of the conventional seat of the conventional bowl or
hopper to provide a low-level assembly, and which at a later date
is susceptible of being combined with an additional elevator of the
prevent invention to provide a raised or high-level assembly. The
seat and associated lid or cover operate in a corresponding manner
in either type of assembly.
SUMMARY OF THE INVENTION
The present invention relates generally to an occupant seat
structure for a toilet bowl or a hopper, and is more particularly
concerned with a combination of components, certain of which can be
initially associated to provide a low-level assembly, and which can
later, by the addition of an elevator component, as the need
arises, be converted to provide a high-level assembly.
A further object of the herein described invention is to provide an
improved annular toilet seat with lateral hand grips for the aid
and convenience of elderly persons and others in assuming a seated
position thereon, arising and otherwise using the toilet bowl.
Another object is to provide a toilet seat of the above character
which is readily adapted for attachment to an elevator structure to
provide an elevated seat at a height level which will permit
invalid persons such as might be confined to a wheel chair to more
easily move into the seat and vice versa, and when seated to occupy
a position which will not cause the discomfort and other
undesirable effects effects which may attend the use of a low-level
seat.
Still another object is to provide a seating structure of the
character described which permits the use of a hinged lid or cover
with the seat, and which makes provision for the operative
association and adjustment of the seat and lid to adapt it to
either a low-level assembly or a high-level assembly.
It is also an object to provide a composite seat structure which
includes an improved elevator component which can be fixedly
attached to a toilet bowl, and which at its upper end provides
bracket means for the attachment of a hinged seat and hinged
associated lid or cover.
A still further object includes the provision of a novel and unique
pivot mounting means for hingedly supporting the seat with respect
to an upper waste opening of a toilet bowl or a hopper, and which
by simple reversal operation will serve to adjust the seat in a
fore-and-aft direction with respect to the waste opening.
Further objects and advantages of the present invention will be
brought out in the following part of the specification, wherein
detailed description is for the purpose of fully disclosing the
embodiments of the invention without placing limitations
thereon.

DESCRIPTION OF THE SEVERAL EMBODIMENTS
Referring more specifically to the drawings, for illustrative
purposes the invention in one form is shown as being applied to a
conventional toilet bowl or hopper 10 constructed with the usual
brim 11 which bounds an upper waste disposal opening 12 and
presents an upper flat annular surface 13.
In the embodiment shown in FIG. 1 , an annular seat 14 and
associated cover or a lid 15 are hingedly supported in a high-level
raised position above the brim 11 by means of an intermediate
elevator as generally noted by the numeral 16.
The elevator is formed as a separate component of the assembly and
comprises a tubular wall structure which provides an upstanding
skirt 17 which is provided intermediate its ends with a peripheral
outwardly projecting mounting flange 18 adapted to seat upon the
upper surface 13 of the brim. As thus arranged, the skirt is
divided into an upper extension portion 19 above the flange 18 and
a lower extension portion 20 below the flange 18, and which is
adapted to extend into the waste disposal opening 12 below the
annular surface 13. The elevator as thus positioned provides an
upper continuation of the waste opening 12 at the top of the
elevator. At the rear side of the elevator, the mounting flange 18
is provided with spaced apart extensions 21a and 21b, each of these
extensions being provided with an elongate end slot 22 (FIG. 3) for
receiving therethrough a mounting bolt 23 positioned in an opening
24 of a bowl shelf portion 25 at the rear of the bowl, the bolt 23
being secured by an associated nut 26.
The seat 14 is shown as being of single wall construction, and may
be fabricated by any suitable method of plastic or other suitable
material with reinforcing ribs in a conventional manner. In general
configuration the seat is annular or ring shaped and has a wall
transverse configuration such as to provide a convex upper surface
27. The inner margin of the seat wall is arranged in the lowered
position of the seat to overlap and extend inwardly of the upper
edge of the extension portion 19 of the skirt and define a seat
opening 28 having communication through the skirt with the waste
disposal opening 12 of the bowl.
It is an important feature of the construction of the seat 14 that
it is provided with integrally formed side extensions 29a and 29b
respectively on its opposite sides. It will be observed that these
extensions are outwardly and upwardly inclined and contain openings
30a and 30b so as to provide hand grips 31a and 31b respectively in
elevated positions on opposite sides of the seat.
As best shown in FIG. 1, the lid 15 and seat 14 are arranged for
hinged movements about a common hinge axes to raised and lowered
positions relative to the upper end of the skirt 17. It is
desirable to provide spaced bumpers 32 of rubber or other suitable
material on the underside of the seat structure for engaging the
upper edge of the skirt 17, and in a like manner provide bumpers as
indicated by the numeral 33 on the lid for engagement with the
upper surface 27 of the seat.
Rearwardly spaced hinge lugs 34-34 are arranged at the rear side of
the seat to extend inwardly of similar hinge lugs 35-35 formed at
the rear side of the lid 15. Each set of seat and lid hinge lugs
are supported by pivot means having a construction as will now be
described.
As best shown in FIGS. 3 and 4, the pivot means for each set of
hinge lugs 34 and 35 comprises an elongate member 36 of rodlike
material which is formed with a shank composed of a threaded
straight portion 37 which is joined with an angularly extending
portion 38 with a right angled end portion 39 forming a pivotal
support for the associated hinge lugs 34 and 35. The angularly
extending shank portion 38 in relation to the longitudinal axis of
the end portion 39 is such that the axis of the end portion will be
laterally offset with respect to the axis of the straight shank
portion 37. The straight portion 37 of each member 36 is secured at
the outermost end of a rearwardly extending bracket arm 40 at the
upper end of the skirt 17. The straight portion of the shank is
positioned in a bore passage 41 and retained by upper and lower
nuts 42 and 43 respectively, with underlying washers if desired. It
will be observed that as mounted in FIG. 3, the shank portions 38
are inclined in a direction to offset the axis of the end portion
39 so as to place it inwardly of the shank portion 37.
Referring to FIG. 7, it will be readily appreciated that the seat
14 with its side hand grips will provide desirable benefits for
certain persons who may be able to utilize a low-level seat
arrangement as normally provided for conventional toilet bowls, and
that under said circumstances it may not be necessary to provide
the high-level arrangement with the elevator as shown in FIG. 3.
The seat 14 and associated lid 15 are readily mountable for direct
association with the brim 11 of the bowl or hopper 10. Due to the
difference in the horizontal spacing of the bore passages 41 and
the openings 24 in the bowl shelf portion, with respect to the rear
side of the waste disposal opening 12, provision is made for
appropriately changing the position of the axis of the end portion
39 of the pivot members. For such purpose, the pivot members are
interchanged and reversed so that instead of the portions 38 being
inclined forwardly, they will be inclined rearwardly, as shown in
FIG. 7. In this manner, the seat and lid will be adjusted in a
fore-and-aft direction so as to appropriately position the seat and
lid depending upon whether it is utilized in the low-level
arrangement as shown in FIG. 7 or in the high-level arrangement as
shown in FIG. 3.
From the foregoing description and drawings, it will be clearly
evident that the delineated objects and features of the invention
will be accomplished.
Various modifications may suggest themselves to those skilled in
the art without departing from the spirit of my invention and
hence, I do not wish to be restricted to the specific form shown or
uses mentioned, except to the extent indicated in the appended
claims.
