Abstract
Abstract A mechanized toilet seat and lid has a pair of quadrant shaped housings fitted, one on each side, to the toilet bowl with each housing containing a moveable lever which is directly connected to the separate hinge shafts of the toilet seat and lid. The levers which are used to lift or lower the toilet seat and lid are moved within the housings by inflation of a pair of pleated rubber bags, one of which is used for lifting and the other for returning the seat and lid to the rest position on the toilet bowl. Wooden or plastic seats can be used with the system and the lever movement of the mechanism can be further employed to operate the flushing mechanism of the cistern and the taps of wash basins. Foot bellows are used to activate the pleated air bags.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
150 words
An apparatus operable to move a toilet seat or toilet lid between raised and lowered positions about an axis of rotation relative to an associated toilet bowl, comprising: a housing mounted adjacent to the toilet bowl; an actuating lever disposed within the housing and non-rotatably connected to a hinge carrying the seat or lid, rotation of the actuating lever being effective to cause a corresponding rotation of the seat or lid; a first inflatable bag disposed within the housing and operable to act on one side of the actuating lever to cause it to rotate the seat or lid in one direction; a second inflatable bag also disposed within the housing and operable to act on the opposite side of the actuating lever to cause it to rotate the seat or lid in the other direction; and manually-controllable means for supplying fluid under pressure to the first and second bags.
Claim 2
Independent Claim
150 words
An apparatus operable to move a toilet seat or toilet lid between raised and lowered positions about an axis of rotation relative to an associated toilet bowl, comprising: a housing mounted adjacent to the toilet bowl; an actuating lever disposed within the housing and non-rotatably connected to a hinge carrying the seat or lid, rotation of the actuating lever being effective to cause a corresponding rotation of the seat or lid; a first inflatable bag disposed within the housing and operable to act on one side of the actuating lever to cause it to rotate the seat or lid in one direction; a second inflatable bag also disposed within the housing and operable to act on the opposite side of the actuating lever to cause it to rotate the seat or lid in the other direction; and manually-controllable means for supplying fluid under pressure to the first and second bags.
Claim 3
Dependent Claim
36 words
A mechanism as claimed in claim 1, further comprising counterbalancing means within the housing mounted adjacent to the toilet bowl, the counterbalancing means being specifically adapted to counterbalance the weight of the toilet seat or lid.
Claim 4
Dependent Claim
39 words
An apparatus as claimed in claim 2, wherein said counterbalancing means comprises a coil spring one end of which is operatively connected to the actuating lever and the other end of which is connected to an adjustable tensioning device.
Claim 5
Independent Claim
44 words
An apparatus as claimed in claims 2 or 3, wherein bracket means are provided for mounting the housing onto a conventional toilet bowl, said bracket means being engageable with nuts or bosses used to mount the lid, seat or seat shaft onto the bowl.
Claim 6
Dependent Claim
87 words
An apparatus as claimed in claim 1 comprising a central low pressure air supply; a working fluid consisting of air; means for connecting the central low pressure air supply to the first and second bags thereby providing a means for the working fluid of air to travel between the central low pressure air supply and the first and second bags; further comprising a foot valve to control the travel of the working fluid of air between the central low pressure supply and the first and second bags.
Claim 7
Dependent Claim
26 words
An apparatus as claimed in claim 1, wherein said hinge comprises a splined surface adapted to engage a corresponding splined surface on a seat or lid.
Claim 8
Dependent Claim
20 words
An apparatus as claimed in claim 1, wherein the first and second inflatable bags comprise bellows folded in concertina fashion.
Claim 9
Dependent Claim
20 words
An apparaus as in claim 1 wherein a foot bellows supplies fluid under pressure to the first and second bags.
Claim 10
Dependent Claim
148 words
An apparatus as in claim 1 comprising: an additional housing mounted adjacent to the cistern valve or handle operable to open and close the cistern valve or handle; an actuating lever disposed within the additional housing and nonrotatably connected to the valve or handle of the cistern bowl, rotation of the actuating lever being effective to cause a corresponding rotation of the cistern valve or handle; a first inflatable bag disposed within the additional housing and operable to act on one side of the actuating lever to cause it to rotate the cistern valve or handle in one direction; a second inflatable bag also disposed within the additional housing and operable to act on the opposite side of the actuating lever to cause it to rotate the cistern valve in the opposite direction; and manually controllable means for supplying fluid under pressure to the first and second bags.
Claim 11
Dependent Claim
14 words
An apparatus as claimed in claim 9 whereby the fluid under pressure is air.
Claim 12
Dependent Claim
27 words
An apparatus as claimed in claim 10 whereby the manually controllable means for supplying fluid under pressure to the first and second bags is a foot bellows.
Claim 13
Dependent Claim
41 words
An apparatus as described in claim 10 whereby the air causes operation of the actuating means to raise and lower the toilet seat and operation of the actuating means of the additional housing to operate the cistern water valve or handle.
