Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
96 words
A hinge comprising a pair of adjacent hinge leaves, a plurality of axially aligned hinge knuckles, at least one knuckle on each leaf along the adjacent edge thereof, the knuckles having an aligned bore, a hinge pin axially extending through the aligned bore, a security stud mounted to one leaf, at least a portion of the stud being rotatable with respect to the leaf so that the stud is resistant to cutting, and an aperture in the other leaf through which the stud extends when the leaves are in an overlying position with the hinge closed.
Claim 2
Dependent Claim
96 words
A hinge comprising a pair of adjacent hinge leaves, a plurality of axially aligned hinge knuckles, at least one knuckle on each leaf along the adjacent edge thereof, the knuckles having an aligned bore, a hinge pin axially extending through the aligned bore, a security stud mounted to one leaf, at least a portion of the stud being rotatable with respect to the leaf so that the stud is resistant to cutting, and an aperture in the other leaf through which the stud extends when the leaves are in an overlying position with the hinge closed.
Claim 3

A hinge as defined in claim 1, wherein the stud includes a bore, and a rolling element resistant to cutting is positioned in the bore.
Claim 4
Dependent Claim
16 words
A hinge as defined in claim 2, wherein the rolling element is a hard surface roller.
Claim 5
Dependent Claim
19 words
A hinge as defined in claim 2, wherein the rolling element comprises a plurality of engaging hard surface balls.
Claim 6
Dependent Claim
38 words
A hinge as defined in claim 2, wherein an opening is provided in the one leaf, the stud is staked in the one leaf opening, and said staking reduces the bore diameter to retain the rolling element therein.
Claim 7
Dependent Claim
23 words
A hinge as defined in claim 2, wherein means are provided at the end of the bore to retain the rolling element therein.
Claim 8
Dependent Claim
13 words
A hinge as defined in claim 6, wherein said means comprises a ball.
Claim 9
Dependent Claim
16 words
A hinge as defined in claim 1, wherein the stud is rotatably mounted to the leaf.
Claim 10
Dependent Claim
23 words
A hinge as defined in claim 1, wherein the stud is tapered to facilitate its extension through the aperture in the other leaf.
Claim 11
Dependent Claim
47 words
A hinge as defined in claim 1, in which the stud extends beyond the other hinge leaf a distance at least equal to about the thickness of one leaf to prevent withdrawal of the stud from the aperture when the leaves are displaced one from the other.
Claim 12
Dependent Claim
99 words
A hinge comprising a pair of leaves, a plurality of axially aligned hinge knuckles, at least one knuckle on each leaf along the adjacent edge thereof, the knuckles having an aligned bore, a hinge pin axially extending through the aligned bore, a security stud attached to one leaf, the stud tapered to facilitate its extension through the aperture in the other leaf and provided with a bore and hard surface roller positioned in the bore, and an aperture in the other leaf through which the stud extends when the leaves are in an overlying position with the hinge closed.
Claim 13
Dependent Claim
99 words
A hinge comprising a pair of leaves, a plurality of axially aligned hinge knuckles, at least one knuckle on each leaf along the adjacent edge thereof, the knuckles having an aligned bore, a hinge pin axially extending through the aligned bore, a security stud attached to one leaf, the stud tapered to facilitate its extension through the aperture in the other leaf and provided with a bore and hard surface roller positioned in the bore, and an aperture in the other leaf through which the stud extends when the leaves are in an overlying position with the hinge closed.
Claim 14
Dependent Claim
46 words
A hinge as defined in claim 11, in which the stud extends beyond the other hinge a distance at least equal to about the thickness of one leaf to prevent withdrawal of the stud from the aperture when the leaves are displaced one from the other.
