Inventors: Livio Bof - Web page: https://patentgrep.com/patent/US6296357B1 ## CPC - G02C 1/023: {with lenses secured to the fixing parts by clamping, luting, soldering, gluing without holes or recesses in the lenses (G02C1/04 - G02C1/08 take precedence)} - G02C: SPECTACLES; SUNGLASSES OR GOGGLES INSOFAR AS THEY HAVE THE SAME FEATURES AS SPECTACLES; CONTACT LENSES (trial frames for testing the eyes A61B3/04; goggles or eyeshields not having the same features as spectacles A61F9/00) ## Abstract A device (10) for clamping a lens (11) to a spectacle frame (12) comprises a bridge (16), which is rotatable about a pin (19) fixed to the body of the frontal frame or to the nose pad carrying element of the spectacle, said bridge being provided with two opposite ends relative to said pin, of which: a first end (27) is provided with a thread suitable for cooperating with a screw (26) which is suitable for causing the rotation movement of the bridge about said pin; and the second end (28) directly cooperates with the lens, by exerting a force on the surface of said lens, said force keeping the lens pressed against a conjugate element (22, 24) which is present on the body of the frontal frame and/or of the nose pad carrying element. ## Claims ### Claim 1 A device for clamping a lens to at least one of a frontal frame or to a nose pad carrying element of a spectacle, comprising a bridge rotatable about a fixed pin related to at least one of said frontal frame or nose pad carrying element, one end of said bridge having first means suitable for cooperating with the surface of said lens to clamp between said one end and the body of at least one of said frontal frame or nose pad carrying element, and the other end of said bridge having second means suitable for controlling the rotation movement of the bridge about said fixed pin to achieve the clamping and the release of said lens. ### Claim 2 (depends on 1) A device according to claim 1, wherein said first means are constituted by an edge of said one end, said edge having a predetermined angle of incidence relative to the surface of said lens. ### Claim 3 (depends on 1) A device according to claim 1, wherein said first means are constituted by said one end either being knurled or cut, or carrying at least a sucker applied thereto. ### Claim 4 A device according to any of the preceding claims, wherein the body of said frontal frame and/or nose pad carrying element is provided with at least a means suitable for constituting a support for said lens. ### Claim 5 (depends on 1) A device according to claim 1, wherein said fixed pin is placed on a base element integral to or made integral to the body of at least one of the said frontal frame or the nose pad carrying element. ### Claim 6 (depends on 5) A device according to claim 5, wherein said base element comprises a pair of uprights provided with aligned holes into which said fixed pin is introduced, said bridge being provided with a hole aligned to said holes, and being in a groove of said base element between said pair of uprights. ### Claim 7 (depends on 6) A device according to claim 6, wherein said hole either has a circular section, or is constituted by a slot inside of which said fixed pin is placed. ### Claim 8 (depends on 1) A device according to claim 1, wherein said second means are respectively constituted by a threaded hole obtained at the said other end of the bridge, as well by a screw introduced in said threaded hole, and the end of said screw, having third guiding means which enables a rectilinear translation of said end so that at least one of the screwing or unscrewing of said screw in said threaded hole causes on one hand a rotation movement of said bridge about the fixed pin, and on the other hand a rectilinear translation movement of the end of said screw along said rectilinear guide. ### Claim 9 (depends on 2) A device according to claim 2, wherein said fixed pin is placed on a base element integral to or made integral to the body of at least one of the said frontal frame or the nose pad carrying element. ### Claim 10 (depends on 9) A device according to claim 9, wherein said base element comprises a pair of uprights provided with aligned holes into which said fixed pin is introduced, said bridge, being provided with a hole aligned to said holes, and being in a groove of said base element between said pair of uprights. ### Claim 11 (depends on 10) A device according to claim 10, wherein said hole either has a circular section, or is constituted by a slot inside of which said fixed pin is placed. ### Claim 12 (depends on 11) A device according to claim 11, wherein said second means are respectively constituted by a threaded hole obtained at the said other end of the bridge, as well by a screw introduced in said threaded hole, and the end of said screw having with third guiding means which enables a rectilinear translation of said end so that at least one of the screwing or unscrewing of said screw in said threaded hole causes on one hand a rotation movement of said bridge about the fixed pin, and on the other hand a rectilinear translation movement of the end of said screw along said rectilinear guide. ### Claim 13 (depends on 3) A device according to claim 3, where said fixed pin is placed on a base element integral to or made integral to the body of at least one of the said frontal frame or the nose pad carrying element. ### Claim 14 (depends on 13) A device according to claim 13, wherein said base element comprises a pair of uprights provided with aligned holes into which said fixed pin is introduced, said bridge, being provided with a hole aligned to said holes, and being in a groove of said base element between said pair of uprights. ### Claim 15 (depends on 14) A device according to claim 14, wherein said hole either has a circular section, or is constituted by a slot inside of which said fixed pin is placed. ### Claim 16 (depends on 15) A device according to claim 15, wherein said second means are respectively constituted by a threaded hole obtained at the said other end of the bridge, as well by a screw introduced in said threaded hole, and the end of said screw having with third guiding means which enables a rectilinear translation of said end so that at least one of the screwing or unscrewing of said screw in said threaded hole causes on one hand a rotation movement of said bridge about the fixed pin, and on the other hand a rectilinear translation movement of the end of said screw along said rectilinear guide. ### Claim 17 (depends on 4) A device according to claim 4, wherein fixed pin is placed on a base element integral to or made integral to the body of at least one of the said frontal frame or the nose pad carrying element. ### Claim 18 (depends on 17) A device according to claim 17, wherein said base element comprises a pair of uprights provided with aligned holes into which said fixed pin is introduced, said bridge, being provided with a hole aligned to said holes, and being in a groove of said base element between said pair of uprights. ### Claim 19 (depends on 18) A device according to claim 18, wherein said hole either has a circular section, or is constituted by a slot inside of which said fixed pin is placed. ### Claim 20 (depends on 19) A device according to claim 19, wherein said second means are respectively constituted by a threaded hole obtained at the said other end of the bridge, as well by a screw introduced in said threaded hole, and the end of said screw having with third guiding means which enables a rectilinear translation of said end so that at least one of the screwing or unscrewing of said screw in said threaded hole causes on one hand a rotation movement of said bridge about the fixed pin, and on the other hand a rectilinear translation movement of the end of said screw along said rectilinear guide.
