Abstract
Abstract A hinge construction for use, by way of example, in a fenestration construction for pivotally supporting a closure member along an edge of a window opening and allowing the closure member to be pivoted through 180* without interference with adjacent structure. The hinge construction comprises two mating or interfitted extruded hinge members having a cross-sectional shape whereby the members may be assembled by relative longitudinal slidable engagement and thereafter cannot be disassembled throughout pivotal movement of one of the hinge members with respect to the other.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
188 words
In a hinge construction, the combination of: a pair of longitudinally extending mating hinge members including plate portions having front faces; hinge portions extending from said plate portions and having longitudinal edge arcuate sections in nested concentric relation in one position of said hinge members; one of said hinge members being normally fixed and the other hinge member being swingable with respect thereto about progressively changing hinge axes during movement of the swingable hinge member; said arcuate section of the fixed hinge member terminating in an edge extremity spaced from the opposed surface of its flange portion a distance less than the external diameter of the arcuate section of said swingable hinge member; said arcuate section of the swingable hinge member having an edge extremity spaced from the front face of its plate portion a distance approximately that of the radius of the external surface of the fixed arcuate section whereby contact of said external surface of said fixed arcuate section maintains interengagement of the arcuate sections to maintain assembly of said hinge members while said swingable hinge member is turned through an angle of at least 180*.
Claim 2
Dependent Claim
188 words
In a hinge construction, the combination of: a pair of longitudinally extending mating hinge members including plate portions having front faces; hinge portions extending from said plate portions and having longitudinal edge arcuate sections in nested concentric relation in one position of said hinge members; one of said hinge members being normally fixed and the other hinge member being swingable with respect thereto about progressively changing hinge axes during movement of the swingable hinge member; said arcuate section of the fixed hinge member terminating in an edge extremity spaced from the opposed surface of its flange portion a distance less than the external diameter of the arcuate section of said swingable hinge member; said arcuate section of the swingable hinge member having an edge extremity spaced from the front face of its plate portion a distance approximately that of the radius of the external surface of the fixed arcuate section whereby contact of said external surface of said fixed arcuate section maintains interengagement of the arcuate sections to maintain assembly of said hinge members while said swingable hinge member is turned through an angle of at least 180*.
Claim 3
Dependent Claim
41 words
In a hinge construction as stated in claim 1 wherein said arcuate sections include external and internal part-cylindrical surfaces whereby said hinge axis during part of said turning of said swingable member is coincident with the axes of said part-cylindrical surfaces.
Claim 4
Dependent Claim
27 words
In a hinge construction as stated in claim 1 wherein said edge extremity of said arcuate section of said fixed swingable member is tapered in cross section.
Claim 5
Dependent Claim
62 words
In a hinge construction as stated in claim 1 wherein said arcuate section of said swingable member subtends an angle of approximately 270* as measured from its point of tangency with its flange portion; and wherein said outer arcuate edge section of said fixed member subtends an angle of approximately 240* as measured from its point of tangency of its flange portion.
Claim 6
Dependent Claim
39 words
In a hinge construction as stated in claim 1 wherein said hinge members are movable longitudinally relative to each other for assembly of said nested arcuate edge sections; and means for holding said hinge members against relative longitudinal movement.
