DETAILED DESCRIPTION OF THE INVENTION
[0010] Referring to the drawing wherein like elements have like
numerals, there is shown in FIG. 1 a toilet seat lifting apparatus
10 according to the present invention.
[0011] Apparatus 10 may be mounted next to a conventional commode
11 or may be incorporated into the design of commode 11. Commode 11
may include a bowl 12, a tank 14 mounted on the bowl 12, and a seat
16 mounted on the bowl 12 via a hinge 18.
[0012] Apparatus 10 preferably includes a base 20 and a mounting
wall 22. Base 20 preferably lies on the floor next to bowl 12 and
prevents apparatus 10 moving with relation to bowl 12. For example,
base 20 may be attached to bowl 12 via a banding strap (not shown).
The mounting wall 22 is preferably affixed perpendicularly to base
20. It is possible to eliminate the base 20 and mounting wall 22,
if the components, mentioned below, are mounted directly onto the
bowl 12. For convenience, the invention will be described with the
base 20 and mounting wall 22, but is not so limited. Base 20 and
mounting wall 22 may be decorated, e.g., wood veneer, paint,
decorative stickers and the like.
[0013] Apparatus 10 preferably includes seat lifting mechanism 23,
seat lowering mechanism 38, and flush mechanism 50 (each will be
discussed in greater detail below). Operation of apparatus 10 will
be discussed after presentation of its major components.
[0014] Seat lifting mechanism 23 preferably includes seat lifting
pedal 24, seat lifting pivot 26, lifting rod pivot 28, lifting rod
30, seat pivot 34, and lifting rod guide 36. Pedal 24 is pivotally
mounted on wall 22 via pivot 26. Pedal 24 is pivotally coupled to
lifting rod 30 via rod pivot 28. Rod 30 is pivotally coupled to
seat 16 via pivot 34. Pivot 34 is preferably located between hinge
18 and the midpoint of seat 16 (as measured from front to back of
the seat). Preferably, rod 30 includes a lifting rod adjustor 32
for coupling the lifting mechanism 23 to seat 16 of commodes of
varying height. Rod 30 also includes a portion for engagement with
flush mechanism 50 (discussed in greater detail below). Preferably,
this portion of rod 30 extends perpendicularly from arm 24 at pivot
28. Adjustor 32 may be a threaded rod and nut, or a telescoping
arm, or a slotted plate with a bolt and nut adjustor. Optionally, a
return spring 35 is connected to flush arm 24 and base 20 or wall
22. Return spring 35 may be necessary when the seat 16 is to light
in weight to return the seat 16 to the lower position. Rod guide 36
is mounted on wall 22, so that rod 30 is movably confined between
the wall 22 and guide 36. While guide 36 is shown as a plate, it
may be any guide such as: an eyelet (not shown) affixed to wall 22
with rod 30 movably confined within the eye, or a slotted plate
(not shown) affixed to wall 22 with rod 30 being confined within
the slot.
[0015] Seat lowering mechanism 38 preferably includes: an anchor
40, a cylinder 42, a cylinder adjustment mechanism 44, and coupler
pivot 48. Anchor 40 is affixed to either base 20 or mounting wall
22. Cylinder 42 is connected to lifting pedal 24 via coupler pivot
48. Cylinder 42 is connected to anchor 40 via cylinder rod 46 (best
seen in FIG. 2). Cylinder adjustment mechanism 44 is preferably
mounted on cylinder 42 and adjustment is effected via adjustment
knob 45. Cylinder 42 allows seat 16 to return to its lower position
without "slamming" into the bowl 12.
[0016] Cylinder 42 may be air operated or water operated. In FIG.
1, the air operated cylinder is illustrated. In FIG. 4, the water
operated cylinder is illustrated. Referring to FIG. 4, cylinder 42'
is connected to water supply 80 via hose 82, pedal 24' and hose 86.
Spent water from cylinder 42 is returned to tank 14 via hose 88. In
this embodiment, seat lifting may be accomplished solely by action
to the water-activated cylinder; foot pedal 24, however, is
preferably retained, but is optional.
[0017] Flush mechanism 50 preferably includes: a flush arm 52, a
flush pivot 54, and a flush chain 62. The combined weight of flush
arm 52 (i.e., that part of arm 52 on the right side of pivot 54)
and flush chain 62 cannot exceed the weight of the flapper (not
shown) located within tank 14. Flush arm 52 is pivotally mounted to
wall 22 via flush pivot 54. Flush arm 52 is connected to flush
handle 64 via flush chain 62. Flush chain 62 may be a chain, strap,
or rod, and may be adjustable in length to accommodate commodes 11
of various sizes. The length of arm 52 may be increased or decrease
by the flush arm adjustment mechanism 56. Adjustment mechanism 56
is illustrated as a plate with a plurality of holes therethrough,
but is not so limited and a slotted plate may also be used. One end
of arm 52 includes a lower flush arm engagement surface 58 and
upper flush arm engagement surface 60. Lower surface 58 is curved,
so that as rod 30 that extends out of pivot 28 engages surface 58,
it passes easily. Upper surface 60 is flat, so that as rod 30
engages surface 60, rod 30 pushes arm 52 and thereby activates the
flush.
[0018] Additionally, flush device 50 preferably includes a device
53 that allows flushing without raising seat 16. Device 53
preferably includes a flush pedal 55, flush pedal pivot 57, and
flush pedal push rod 59. Flush pedal 55 is pivotally connected to
wall 22 via pivot 57. Flush pedal 55 is connected to flush arm
adjustment mechanism 56 via flush pedal push arm 59.
[0019] In operation (FIGS. 1-3), seat lifting pedal 24 is depressed
causing lifting rod 30 to push seat 16 to a second (erect or
practically vertical) position from a first (rest or horizontal)
position, cylinder rod 46 to extend from cylinder 42, and rod 30 to
be positioned above upper flush engagement surface 60. See FIG. 2.
Seat 16 remains in the second position, so long as lifting pedal 24
is depressed. Once pressure is removed from pedal 24, seat 16,
preferably under its own weight (but, if necessary with the
assistance of return spring 35), returns to its first position. As
seat 16 begins its return to the first position, cylinder 42 slows
the fall of the seat 16. The seat's rate of return is controlled by
cylinder adjustment mechanism 44. Mechanism 44 may be a valve that
regulates the release of fluid (gas or liquid) from cylinder 42.
Additionally, rod 30 engages upper flush arm engagement surface 60
and depresses flush arm 52 and activates the flush by pulling flush
chain 62. See FIG. 3. Thereafter, apparatus 10 is returned to its
original condition and ready for another lift/lower/flush
cycle.
[0020] In operation (water cylinder), foot pedal 24' is depressed
causing cylinder 42' to rise and lift seat 16 and rod 30 to be
positioned above upper flush engagement surface 60. Seat 16 remains
in the second position, so long as lifting pedal 24' is depressed.
Once pressure is removed from pedal 24', seat 16, preferably under
its own weight (but, if necessary with the assistance of return
spring 35), returns to its first position. When seat 16 begins its
return to the first position, cylinder 42' slows the fall of the
seat 16. The seat's rate of return is controlled by cylinder
adjustment mechanism 44. Mechanism 44 may be a valve that regulates
the release of fluid (gas or liquid) from cylinder 42.
Additionally, rod 30 engages upper flush arm engagement surface 60
and depresses flush arm 52 and activates the flush by pulling flush
chain 62. See FIG. 3. Thereafter, apparatus 10 is returned to its
original condition and ready for another lift/lower/flush
cycle.
[0021] In operation, either embodiment may be flushed without
lifting seat 16 or touching handle 64. When device 10 is in the
position shown in FIG. 1, depression of flush pedal 55 will cause
flush arm 52 to pivot downwardly and flush chain 62 to pull handle
64. Flush pedal 55 may be depressed with the toe or heel of a
foot.
[0022] The present invention may be embodied in other forms without
departing from the spirit and the essential attributes thereof,
and, accordingly, reference should be made to the appended claims,
rather than to the foregoing specification, as indicated the scope
of the invention.
