Abstract
Abstract A spectacle frame of the type having a pair of lens-holding rings joined by a bridge split into two parts by a cut extending from one lens-holding ring to the other is described. The frame is shown to include a decorative spring-steel fastener removaly fitted on the front of the bridge and engaging the upper and lower surfaces of the bridge so as to hold the two parts of the bridge together. The fastener has a curved extremity engaging the lower surface of the bridge, a concave front face, and a slotted latching extremity engaging the upper surface of the bridge, the latter extremity being provided with a tongue for removal of the fastener.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
126 words
A spectacle frame comprising: a pair of split lens-holding rings; a bridge split into an upper part and a lower part by a cut extending from one of said rings to the other, said parts being formed with respective ridges, each of said parts being integral with both rings, said cut having a stepped profile in a vertical transverse plane whereby said parts overlap over a predetermined range of relative vertical displacement; and a resilient clip engaging said bridge from above and from below for urging said parts into mutual contact along said cut, said clip having upper and lower extremities respectively curved about said ridges; one of said extremities being vertically slitted with formation of a multiplicity of parallel strips bent around the associated ridge.
Claim 2
Dependent Claim
126 words
A spectacle frame comprising: a pair of split lens-holding rings; a bridge split into an upper part and a lower part by a cut extending from one of said rings to the other, said parts being formed with respective ridges, each of said parts being integral with both rings, said cut having a stepped profile in a vertical transverse plane whereby said parts overlap over a predetermined range of relative vertical displacement; and a resilient clip engaging said bridge from above and from below for urging said parts into mutual contact along said cut, said clip having upper and lower extremities respectively curved about said ridges; one of said extremities being vertically slitted with formation of a multiplicity of parallel strips bent around the associated ridge.
Claim 3
Dependent Claim
31 words
A spectacle frame as defined in claim 1 wherein said clip has a midportion between said extremities curved toward said bridge and bearing upon same in the region of said cut.
Claim 4
Dependent Claim
20 words
A spectacle frame as defined in claim 1 wherein said stepped profile defines a vertical contact surface between said parts.
Claim 5
Dependent Claim
40 words
A spectacle frame as defined in claim 3 wherein one of said extremities curves around the associated projecting formation forwardly Of said contact surface, the other of said extremities curving around the associated projecting formation rearwardly of said contact surfaces.
Claim 6
Dependent Claim
44 words
A spectacle frame as defined in claim 6 wherein said cut lies at a level farther from said one of said extremities forwardly of said contact surface and lies at a level farther from said other of said extremities rearwardly of said contact surface.
Claim 7
Dependent Claim
147 words
A spectacle frame comprising: a pair of split lens-holding rings; a bridge split into an upper part and a lower part by a cut extending from one of said rings to the other, said parts being formed with respective ridges, each of said parts being integral with both rings, said cut having a stepped profile in a vertical transverse plane defining a stepped profile defining a vertical contact surface between said parts whereby said parts overlap over a predetermined range of relative vertical displacement; and a resilient clip engaging said bridge from above and from below for urging said parts into mutual contact along said cut, said clip having upper and lower extremities respectively curved about said ridges; one of said extremities curving around the associated ridge forwardly of said contact surface, the other of said extremities curving around the associated ridge rearwardly of said contact surfaces.
Claim 8
Dependent Claim
147 words
A spectacle frame comprising: a pair of split lens-holding rings; a bridge split into an upper part and a lower part by a cut extending from one of said rings to the other, said parts being formed with respective ridges, each of said parts being integral with both rings, said cut having a stepped profile in a vertical transverse plane defining a stepped profile defining a vertical contact surface between said parts whereby said parts overlap over a predetermined range of relative vertical displacement; and a resilient clip engaging said bridge from above and from below for urging said parts into mutual contact along said cut, said clip having upper and lower extremities respectively curved about said ridges; one of said extremities curving around the associated ridge forwardly of said contact surface, the other of said extremities curving around the associated ridge rearwardly of said contact surfaces.
