Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
60 words
A mattress characterised in that it incorporates a plurality of air supply chambers which are connected to air supply conduits, a plurality of inflatable air sacs being mounted on the mattress for supporting a person thereon and being connected to ports in the chambers so that air can be supplied to the air sacs via the conduits and supply chambers.
Claim 2
Dependent Claim
60 words
A mattress characterised in that it incorporates a plurality of air supply chambers which are connected to air supply conduits, a plurality of inflatable air sacs being mounted on the mattress for supporting a person thereon and being connected to ports in the chambers so that air can be supplied to the air sacs via the conduits and supply chambers.
Claim 3
Dependent Claim
79 words
A mattress characterised in that air header chambers are mounted in pairs on opposite longitudinal sides of the mattress, said chambers having ports for connection to inflatable air sacs which, when inflated provide a support surface for a person, and conduits being provided to connect some header chambers with a source of pressurised air and other chambers to exhaust ; to atmosphere so that the air can be supplied to the air sacs and an air flow maintained therethrough.
Claim 4
Dependent Claim
79 words
A mattress characterised in that air header chambers are mounted in pairs on opposite longitudinal sides of the mattress, said chambers having ports for connection to inflatable air sacs which, when inflated provide a support surface for a person, and conduits being provided to connect some header chambers with a source of pressurised air and other chambers to exhaust ; to atmosphere so that the air can be supplied to the air sacs and an air flow maintained therethrough.
Claim 5
Dependent Claim
90 words
A mattress which is formed from a foamed plastics or rubber material characterised in that conduits are provided in the interior of the mattress and are arranged to feed pressurised air to header chambers mounted at one side of the mattress, each said chamber including at least one port for connection to an inlet aperture in an inflatable air sac, each inflatable sac also having an outlet aperture which is connected to an exhaust valve so that air flow through the air sacs can be maintained at a predetermined rate.
Claim 6
Dependent Claim
90 words
A mattress which is formed from a foamed plastics or rubber material characterised in that conduits are provided in the interior of the mattress and are arranged to feed pressurised air to header chambers mounted at one side of the mattress, each said chamber including at least one port for connection to an inlet aperture in an inflatable air sac, each inflatable sac also having an outlet aperture which is connected to an exhaust valve so that air flow through the air sacs can be maintained at a predetermined rate.
Claim 7
Dependent Claim
63 words
A mattress according to claim 3 wherein the outlet aperture from each inflatable sac is connected to an exhaust header chamber mounted on the opposite side of the mattress from a supply header chamber with the inflatable sac extending therebetween transversely of the mattress, the exhaust header chamber being connected to an exhaust conduit which discharges to atmosphere through a flow control valve.
Claim 8
Dependent Claim
33 words
A mattress according to claim 4 wherein the mattress, conduits and header chambers are all sufficiently flexible for the mattress to be contoured without impeding the flow of air to the inflatable sacs.
Claim 9
Dependent Claim
20 words
A mattress according to claim 4 wherein the inflatable sacs are releasably connected to the ports in the header chambers.
Claim 10
Dependent Claim
56 words
A mattress according to claim 4 wherein the mattress is mounted on a baseboard and at least one inflatable bellows is disposed between the baseboard and the mattress, the bellows being connected to a source of pressurised air via a control valve so that the mattress can be contoured by admission of air to the bellows.
Claim 11
Dependent Claim
22 words
A mattress according to claim 7 wherein the bellows is supplied with air by means of a conduit passing through the mattress.
Claim 12
Dependent Claim
112 words
A remotely operated air valve which comprises a chamber having an inlet and an outlet, the outlet including a tube which projects into the chamber and the chamber being divided by a flexible diaphragm so that the outlet and inlet are in the same part of ; the chamber, the diaphragm being movable between two extreme positions in one of which the diaphragm seals the end of the inlet tube and the other allows air to escape into the chamber through the tube, the other part of the chamber being pressurised and the position of the diaphragm being controllable by venting or not venting air from the second part of the chamber.
Claim 13
Dependent Claim
112 words
A remotely operated air valve which comprises a chamber having an inlet and an outlet, the outlet including a tube which projects into the chamber and the chamber being divided by a flexible diaphragm so that the outlet and inlet are in the same part of ; the chamber, the diaphragm being movable between two extreme positions in one of which the diaphragm seals the end of the inlet tube and the other allows air to escape into the chamber through the tube, the other part of the chamber being pressurised and the position of the diaphragm being controllable by venting or not venting air from the second part of the chamber.
Claim 14
Dependent Claim
77 words
A connector for use with a low pressure air supply conduit which comprises male and female tubular parts, the male part having a recess for reception of a resilient latch member carried by the female part when the two parts are assembled together and a portion of the male part being shaped so as to raise the latch when the two parts are rotated relatively to one another and thus permit the two parts to be disassembled.
