Abstract

Abstract A respiration system is provided which is useful to protect a wearer thereof in potentially hazardous atmospheres which are not immediately dangerous to life or health. The respiration system comprises a flexible cape member having an aperture defining a neck engaging collar through which a wearer's head is passed. A ring structure surrounds the aperture and is attached to the cape member to form and hold an inner portion of the cape member in a ruff configuration which extends radially outwardly from the aperture to the ring structure. A conduit passes through a first orifice in the cape member, within the inner portion thereof, for release of respiratory air above an upper surface of the ruff configuration. A head enclosure is sealing affixed to the cape member and surrounds the ruff configuration.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 124 words
A respiration system comprising: a flexible, substantially air impervious cape member having opposed first and second surfaces and defining an aperture and a first orifice, said aperture and said orifice each passing between said surfaces; a ring structure of sufficient size to surround said aperture and said first orifice, when said ring structure is disposed along one of said surfaces, to define an inner portion of said cape member; attachment means for attaching said ring structure to one of said surfaces, said ring structure and attachment means co-operating to hold said inner portion in a radially outwardly extending ruff configuration with respect to said first orifice; and, an air impervious head enclosure being sealingly affixed to said cap member to surround said ruff configuration.
Claim 2
Dependent Claim 124 words
A respiration system comprising: a flexible, substantially air impervious cape member having opposed first and second surfaces and defining an aperture and a first orifice, said aperture and said orifice each passing between said surfaces; a ring structure of sufficient size to surround said aperture and said first orifice, when said ring structure is disposed along one of said surfaces, to define an inner portion of said cape member; attachment means for attaching said ring structure to one of said surfaces, said ring structure and attachment means co-operating to hold said inner portion in a radially outwardly extending ruff configuration with respect to said first orifice; and, an air impervious head enclosure being sealingly affixed to said cap member to surround said ruff configuration.
Claim 3
Dependent Claim 39 words
The respiration system as in claim 1 further comprising: a first conduit operatively associated with said cape member and being of sufficient construction to channel respiration air through said first orifice from said second surface to said first surface.
Claim 4
Dependent Claim 51 words
The respiration system as in claim 1 or 2 wherein said ring structure includes an annulus, said annulus defining an exterior, circumferential groove, and said attachment means includes an elastomeric ring of sufficient construction to be engagably received within and along said groove to engage said annulus with said second surface.
Claim 5
Dependent Claim 51 words
The respiration system as in claim 3 further comprising a second conduit in communication with said first conduit adjacent said first surface at a first portion of said second conduit, said second conduit being formed substantially in a circular shape and having a second portion thereof adapted to release air therefrom.
Claim 6
Dependent Claim 32 words
The respiration system as in claim 4 wherein said air releasing second portion of said second conduit includes attenuating means for attenuating the sound of air being released from said releasing portion.
Claim 7
Dependent Claim 20 words
The respiration system as in claim 5 wherein said attenuating means is positionable to be held below a wearer's face.
Claim 8
Dependent Claim 47 words
The respiration system as in claim 1 or 2 wherein said cape member defines a pair of exhaust holes therethrough, said exhaust holes being spaced to be between said inner portion and an outer portion of said cape member and to be equidistant from said first aperture.
Claim 9
Dependent Claim 35 words
The respiration system as in claim 7 wherein said sealing affixation of said head enclosure is by an elastomeric ring of sufficient construction to be engagably received within and along said groove of said annulus.
Claim 10
Dependent Claim 66 words
The respiration system as in claim 2 wherein said ring structure comprises a second conduit in communication with said first conduit at a first portion of said second conduit, said second conduit being formed substantially in a circular shape and having a second portion thereof adapted to release air therefrom, and said attachment means attaches said second conduit to said first surface of said cape member.
Claim 11
Dependent Claim 33 words
The respiration system as in claim 9 wherein said air releasing second portion of said second conduit includes attenuating means for attenuating the sound of air being released from said air releasing portion.
Claim 12
Dependent Claim 20 words
The respiration system as in claim 10 wherein said attenuating means is positionable to be held below a wearer's face.
Claim 13
Dependent Claim 39 words
The respiration system as in claim 9 wherein said cape member has an outer portion sealingly engaged with and surrounding said inner portion, said outer portion defining a pair of exhaust holes therethrough being equidistant from said first aperture.
Claim 14
Dependent Claim 186 words
A respiration system comprising: a flexible, substantially air impervious cape member having opposed first and second surfaces, and defining an aperture and a first orifice each passing between said surfaces, said cape member having an inner portion extending radially outwardly from said aperture, said inner portion and said aperture being formed from a cylindrical tube with open ends and an elastic circlet placed over said cylindrical tube at a mid portion thereof, said elastic circlet being of smaller diameter than that of said tube, bringing said ends of said tube together to encase said elastic circlet and sealing said ends together; a ring structure of sufficient size to surround said aperture and said first orifice when said ring structure is disposed along one of said surfaces adjacent said inner portion of said cape member; attachment means for attaching said ring structure to one of said surfaces, said ring structure and attachment means co-operating to hold said inner portion in a radially outwardly extending ruff configuration with respect to said aperture; and, a head enclosure being sealingly affixed to said cap member to surround said ruff configuration.
Claim 15
Dependent Claim 186 words
A respiration system comprising: a flexible, substantially air impervious cape member having opposed first and second surfaces, and defining an aperture and a first orifice each passing between said surfaces, said cape member having an inner portion extending radially outwardly from said aperture, said inner portion and said aperture being formed from a cylindrical tube with open ends and an elastic circlet placed over said cylindrical tube at a mid portion thereof, said elastic circlet being of smaller diameter than that of said tube, bringing said ends of said tube together to encase said elastic circlet and sealing said ends together; a ring structure of sufficient size to surround said aperture and said first orifice when said ring structure is disposed along one of said surfaces adjacent said inner portion of said cape member; attachment means for attaching said ring structure to one of said surfaces, said ring structure and attachment means co-operating to hold said inner portion in a radially outwardly extending ruff configuration with respect to said aperture; and, a head enclosure being sealingly affixed to said cap member to surround said ruff configuration.
Claim 16
Dependent Claim 42 words
The respiration system as in claim 13 wherein said cape member has an outer portion sealed to said sealed ends of said inner portion, said outer portion defining a pair of exhaust holes passing therethrough and being equidistant from said first orifice.
