Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
195 words
A headgear structure for supporting a welding helmet and comprising a headband for circumposition about a wearer''s head, a bridge piece extending between spaced regions of said headband for extension across the wearer''s head, a pair of elongate extensions located on opposite sides of said headband and each looped outwardly and upwardly with its terminal portion proximate to the adjacent region of said bridge piece, securing mens securing said terminal portions of said extensions to said bridge piece, and pivot mens extending through the outer portion of each looped extension for rotatively supporting a welding helmet, said headband and bridge piece and extensions being integrally fabricated of plastic, said securing means detachably securing said terminal portions to said bridge piece, said extensions being flexible to lie sustantially flat and coplanar with said headband and bridge piece in nonuse condition, said extensions each comprising an outstanding portion hingedly connected to a lower adjacent region of said headband, an upstanding portion hingedly connected to and upstanding from the outer extremity of said outstanding portion, and an inwardly extending portion hingedly connected to and extending inwardly from the upper extremity of said upstanding portion to said terminal portion.
Claim 2
Dependent Claim
195 words
A headgear structure for supporting a welding helmet and comprising a headband for circumposition about a wearer''s head, a bridge piece extending between spaced regions of said headband for extension across the wearer''s head, a pair of elongate extensions located on opposite sides of said headband and each looped outwardly and upwardly with its terminal portion proximate to the adjacent region of said bridge piece, securing mens securing said terminal portions of said extensions to said bridge piece, and pivot mens extending through the outer portion of each looped extension for rotatively supporting a welding helmet, said headband and bridge piece and extensions being integrally fabricated of plastic, said securing means detachably securing said terminal portions to said bridge piece, said extensions being flexible to lie sustantially flat and coplanar with said headband and bridge piece in nonuse condition, said extensions each comprising an outstanding portion hingedly connected to a lower adjacent region of said headband, an upstanding portion hingedly connected to and upstanding from the outer extremity of said outstanding portion, and an inwardly extending portion hingedly connected to and extending inwardly from the upper extremity of said upstanding portion to said terminal portion.
Claim 3
Dependent Claim
26 words
A headgear structure according to claim 1, said securing means comprising releasably interfitting formations on said terminal portions and said adjacent regions of said bridge piece.
Claim 4
Dependent Claim
60 words
A headgear structure according to claim 1, said pivot means each comprising an inner fastener element extending nonrotatably through the associated one of said upstanding extension portions, an outer fastener element in threaded rotative engagement with said inner fastener element, and friction means interposed between said outer and inner fastener elements for selectively frictionally holding a welding helmet against rotation.
Claim 5
Dependent Claim
33 words
A headgear structure according to claim 3, in combination with selective releasably interfitting fastener means on and integral with the split end regions of said headband and bridge piece for adjustable connection thereof.
Claim 6
Dependent Claim
45 words
A headgear structure according to claim 1, said outstanding and upstanding portions being relatively thick to resist flexure, and the junctures of said outstanding and upstanding portions with each other and with said headband and inwardly extending portions being relatively thin to define hinged connections.
Claim 7
Dependent Claim
28 words
A headgear structure according to claim 1, said headband and bridge piece being split and flexible to lie substantially flat and coplanar with each other in nonuse condition.
Claim 8
Dependent Claim
26 words
A headgear strUcture according to claim 5 said securing means comprising releasably interfitting formations on said terminal portions and said adjacent regions of said bridge piece.
Claim 9
Dependent Claim
60 words
A headgear structure according to claim 5, said pivot means each comprising an inner fastener element extending nonrotatably through the associated one of said upstanding extension portions, an outer fastener element, in threaded rotative engagement with said inner fastener element, and friction means interposed between said outer and inner fastener elements for selectively frictionally holding a welding helmet against rotation.
