Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
262 words
An arrangement for hinging a temple to the lens retaining portion of a spectacle frame including, a first hinge member rigidly connected to said lens retaining portion, a second hinge member, and a hinge pin connecting said first and second hinge members for relative pivotal movement only, between the fully closed and fully opened positions thereof, connecting means for operatively connecting said second hinge member to said temple comprising an elongated hollow member rigidly mounted on said temple, an extension formed on said second hinge member and extending into said hollow member, means for guiding said extension for movement relative to said temple along a path substantially parallel to said temple including an elongated slot formed in said extension intermediate its ends and guide means rigidly mounted in said hollow member and extending through said slot for operative engagement with at least one end of said slot, and resilient means in said hollow member operatively engaged with said extension for urging said one end of the slot into engagement with said guide means, whereby said temple is adapted to be pivoted about said hinge pin with respect to said lens supporting portion from the fully closed position thereof to an intermediate position wherein the outer corner of said temple engages said lens retaining portion, and from said intermediate position to said fully opened position wherein said hinge pin moves parallel to itself and with respect to said temple along a path such that said temple outer corner defines the pivot axis of said temple and remains engaged with said lens retaining portion.
Claim 2
Dependent Claim
262 words
An arrangement for hinging a temple to the lens retaining portion of a spectacle frame including, a first hinge member rigidly connected to said lens retaining portion, a second hinge member, and a hinge pin connecting said first and second hinge members for relative pivotal movement only, between the fully closed and fully opened positions thereof, connecting means for operatively connecting said second hinge member to said temple comprising an elongated hollow member rigidly mounted on said temple, an extension formed on said second hinge member and extending into said hollow member, means for guiding said extension for movement relative to said temple along a path substantially parallel to said temple including an elongated slot formed in said extension intermediate its ends and guide means rigidly mounted in said hollow member and extending through said slot for operative engagement with at least one end of said slot, and resilient means in said hollow member operatively engaged with said extension for urging said one end of the slot into engagement with said guide means, whereby said temple is adapted to be pivoted about said hinge pin with respect to said lens supporting portion from the fully closed position thereof to an intermediate position wherein the outer corner of said temple engages said lens retaining portion, and from said intermediate position to said fully opened position wherein said hinge pin moves parallel to itself and with respect to said temple along a path such that said temple outer corner defines the pivot axis of said temple and remains engaged with said lens retaining portion.
Claim 3
Dependent Claim
132 words
The hinge arrangement as defined in claim 1, wherein said guide means includes a crossmember rigid with respect to said temple and positioned between said hinge pin and a frEe end of said extension remote from said hinge pin, said arrangement further including, a guide pin having opposed ends extending partway between said crossmember and said extension free end when said temple is opened to said intermediate position, said guide pin having a head at one end in permanent contact with said crossmember and the other end of said guide pin acting as a stop together with said extension free end, said resilient means being compressed between the head end of said guide pin and said extension free end to urge said one end of said slot into engagement with said crossmember.
Claim 4
Dependent Claim
43 words
The hinge arrangement as defined in claim 2, wherein said wherein said cross member includes a projection extending towards said hinge pin adapted to engage said second hinge member near said hinge pin to assist in guiding the movement of said hinge pin.
Claim 5
Dependent Claim
106 words
The hinge arrangement as defined in claim 1, wherein said guide means comprises a rod mounted in said hollow member extending transversely to the lengthwise direction of said temple and positioned between said hinge pin and a free end of said extension remote from said hinge pin, said resilient means being compressed between said rod and said extension free end, to urge said one end of said slot into engagement with said guide means, said slot being adapted to slide with respect to said rod between said intermediate and said fully open positions of said temple to determine the path along which said hinge pin moves.
Claim 6
Dependent Claim
38 words
The hinge arrangement as defined in claim 4, wherein said guide slot causes said hinge pin to move along a path substantially tangent to a circular cylinder with a center coincident with the outer corner of the temple.
Claim 7
Dependent Claim
38 words
The hinge arrangement as defined in claim 4, wherein said guide slot causes said hinge pin to move along a path that at least very closely approximates a circular arc centered at the outer corner of the temple.
Claim 8
Dependent Claim
76 words
The hinge arrangement as defined in claim 1, wherein said hollow member includes a generally triangularly shaped platform rigidly mounted adjacent said temple and defining a guide path along an acute angle with said temple in the lengthwise direction thereof for guiding said hinge pin along a path substantially tangent to a circular cylinder centered at the outer corner of said temple during movement of said temple between said intermediate position and said fully opened position.
Claim 9
Dependent Claim
46 words
The hinge arrangement as defined in claim 7, wherein said resilient means is positioned in compression, between said free end of said extension remote from said hinge pin and said guide means, to urge said one end of said slot into engagement with said guide means.
Claim 10
Dependent Claim
42 words
The hinge arrangement as defined in claim 1, including a distorting articulated parallelogram cooperating with said second hinge member extension to cause said hinge pin to move at least approximately along a circular arc centered at the outer corner of the temple.
Claim 11
Dependent Claim
45 words
The hinge arrangement as defined in claim 9, wherein said distorting articulated parallelogram includes first and second links spaced along said second hinge member extension, and pivot means for pivotally connecting a respective link to said second hinge member extension and to said hollow member.
Claim 12
Dependent Claim
47 words
The hinge arrangement as defined in claim 10, wherein said resilient means is connected between one of said pivot means connecting one of said links to said hollow member and another of said pivot means connecting the other of said links to said second hinge member extension.
Claim 13
Dependent Claim
28 words
The hinge arrangement as defined in claim 4, wherein said guide slot cooperates with said rod to determine the maximum extent to which the sidepiece can be opened.
