Abstract
Abstract A spectacle front hinge pinning system having a front hinge connecting the temples of the spectacle to its frame. The front hinge has a plurality of mating barrels, each having its own bore with these bores being aligned. The spectacle hinge pin is inserted downwardly through the aligned bores in the barrels to maintain the barrels in aligned arrangement. The hinge pin has an elongated body made of a plastic material with a head formed on one of its ends. It has a shank portion extending from the head. A relieved section is formed adjacent the shank portion and it has a diameter less than that of the shank portion. A lead portion is located adjacent said relieved section and it has a barb formed thereon that extends transversely with respect to the axis of the lead portion outwardly beyond the outer surface of said relieved section to extend radially beneath the end lower barrel of the hinge.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
140 words
A spectacle hinge pin comprising an elongated resilient body having a head at one end and a tip at the opposite end, a shank portion extending from the head of the body with the shank portion of a predetermined diameter, a relieved section adjacent said shank portion having a diameter less than that of said shank portion, a lead portion having its one end adjacent said relieved section and having a tip formed at its opposite end, barb means adjacent said relieved section formed on said lead portion that extend transversely of the lead portion outwardly beyond the outer surface of said relieved section, said lead portion being of a diameter less than said shank and of a length greater than said shank portion whereby it may be grasped at its tip for pulling the pin into the hinge means.
Claim 2
Dependent Claim
140 words
A spectacle hinge pin comprising an elongated resilient body having a head at one end and a tip at the opposite end, a shank portion extending from the head of the body with the shank portion of a predetermined diameter, a relieved section adjacent said shank portion having a diameter less than that of said shank portion, a lead portion having its one end adjacent said relieved section and having a tip formed at its opposite end, barb means adjacent said relieved section formed on said lead portion that extend transversely of the lead portion outwardly beyond the outer surface of said relieved section, said lead portion being of a diameter less than said shank and of a length greater than said shank portion whereby it may be grasped at its tip for pulling the pin into the hinge means.
