Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
98 words
A corner fillet composed of an elongated one-piece member that consists of a mid section and one end section on each side of the mid section, said end sections being joined to said mid section by two spaced apart hinge means that are parallel to each other and parallel to the longitudinal axis of said elongated one-piece member, said end sections being adapted to fold toward each other along said hinge lines so as to interengage along a line that is adjacent to the longitudinal outer side edges of said end sections to thereby form a corner fillet.
Claim 2
Dependent Claim
98 words
A corner fillet composed of an elongated one-piece member that consists of a mid section and one end section on each side of the mid section, said end sections being joined to said mid section by two spaced apart hinge means that are parallel to each other and parallel to the longitudinal axis of said elongated one-piece member, said end sections being adapted to fold toward each other along said hinge lines so as to interengage along a line that is adjacent to the longitudinal outer side edges of said end sections to thereby form a corner fillet.
Claim 3
Dependent Claim
22 words
A corner fillet according to claim 1 wherein in its folded and interengaged position the corner fillet is of generally triangular configuration.
Claim 4
Dependent Claim
34 words
A corner fillet according to claim 2 wherein one end section of the triangular configuration has a concave disposition and is greater in width than either the other end section or said mid section.
Claim 5
Dependent Claim
48 words
A corner fillet according to claim 3, wherein one of said end sections is disposed substantially at right angles to said mid section and the other end section tends to force said one end section and said mid section apart and into engagement with their respective adjacent surfaces.
Claim 6
Dependent Claim
24 words
A corner fillet according to claim 1, wherein said hinge means are formed by reducing the thickness of the one-piece member along longitudinal lines.
Claim 7
Dependent Claim
18 words
A corner fillet according to claim 1, wherein the corner fillet is composed of a synthetic plastics material.
Claim 8
Dependent Claim
14 words

Claim 9
Dependent Claim
111 words
A corner fillet comprising an elongated one-piece member that consists of a mid section and one end section on each side of the mid section, said end sections being joined to said mid section by two spaced apart hinge means that are parallel to each other and parallel to the longitudinal axis of said elongated one-piece member, the first of said end sections and said mid section being disposed at approximately right angles to each other, the second of said end sections extending in a concave disposition between its line of hinge connection with said mid section and an elongated ridge extending along the outer edge of said first end section.
Claim 10
Dependent Claim
111 words
A corner fillet comprising an elongated one-piece member that consists of a mid section and one end section on each side of the mid section, said end sections being joined to said mid section by two spaced apart hinge means that are parallel to each other and parallel to the longitudinal axis of said elongated one-piece member, the first of said end sections and said mid section being disposed at approximately right angles to each other, the second of said end sections extending in a concave disposition between its line of hinge connection with said mid section and an elongated ridge extending along the outer edge of said first end section.
Claim 11
Dependent Claim
17 words
A corner fillet according to claim 8, wherein said mid section is provided with notches or serrations.
Claim 12
Dependent Claim
24 words
A corner fillet according to claim 8, wherein said hinge means are formed by reducing the thickness of the one-piece member along longitudinal lines.
Claim 13
Dependent Claim
