Adjustable eyeglass temple

Claim 2

A pair of elongated members adapted for longitudinal adjusting movement relative to one another, a slotted opening in one of said members with a plurality of longitudinally spaced enlarged pocket portions, a pin mounted in a fixed position in the other member engaging through said slotted opening which seats in a selected one of said enlarged pocket portions of said slot to releasably retain said members in a selected position, said slot between said enlarged pocket portions being smaller in cross section than the cross section of the pin, said members being of a predetermined cross sectional relationship to permit flexing displacement of said other member upon longitudinal adjusting movement of said members relative to one another to permit positioning of said pin in a selected pocket portion of said slot, said slotted opening being resiliently yieldable for said pin movement and snap pin enlargement in said enlarged pocket portions.

Claim 3

An adjustable eyeglass temple comprising a forward member for hinged connection to an eyeglass front piece, a rearward member for extension over a wearer's ear, said forward and rearward members being in telescopic extensile and retractile relation with one member interiorly of the outer member, one of said members having an elongated channel therein, the other member engageable in said channel and having a slotted opening with a plurality of longitudinally spaced enlarged pocket portions, a pin mounted in a fixed position in said one member engaging through said slotted opening which seats in a selected one of said enlarged pocket portions of said slot to releasably retain said members in a selected position, said slot between said enlarged pocket portions being smaller in cross section than the cross section of the pin, said members being of a predetermined cross sectional relationship to permit flexing displacement of said other member upon longitudinal adjusting movement of said members relative to one another to permit positioning of said pin in a selected pocket portion of said slot, said slotted opening being resiliently yieldable for said pin movement and snap pin enlargement in said enlarged pocket portions.

Claim 4

An adjustable eyeglass temple comprising a forward member for hinged connection to an eyeglass front piece, a rearward member for extension over a wearer's ear, said forward and rearward members being in telescopic extensile and retractile relation with one member interiorly of the outer member, one of said members having an elongated channel therein, the other member engageable in said channel and having a slotted opening with a plurality of longitudinally spaced enlarged pocket portions, a pin mounted in a fixed position in said one member engaging through said slotted opening which seats in a selected one of said enlarged pocket portions of said slot to releasably retain said members in a selected position, said slot between said enlarged pocket portions being smaller in cross section than the cross section of the pin, said members being of a predetermined cross sectional relationship to permit flexing displacement of said other member upon longitudinal adjusting movement of said members relative to one another to permit positioning of said pin in a selected pocket portion of said slot, said slotted opening being resiliently yieldable for said pin movement and snap pin enlargement in said enlarged pocket portions.

Claim 5

An adjustable eyeglass temple according to claim 2, said elongated opening comprising a longitudinal slot.

Claim 6

An adjustable eyeglass temple according to claim 3, said enlarged pocket portions comprising a plurality of cut-outs spaced along and opening into said slot.

Claim 7

An adjustable eyeglass temple according to claim 4, said slot having its opposite ends extending beyond said cut-outs for sufficient resilient lateral deflection of said interior part to yieldably open said slot to snap engage said pin in the endmost cut-outs.

Claim 8

An adjustable eyeglass temple as claimed in claim 5 including means preventing lateral displacement of said members relative to one another beyond engagement of said pin in the endmost cut-outs.

Claim 9

An adjustable eyeglass temple according to claim 5, in combination with constriction means in said slot beyond the endmost cut-out at one end of said slot to prevent pin movement beyond said one endmost cut-out.

Claim 10

An adjustable eyeglass temple as claimed in claim 5 wherein the outer terminal ends of said slot are enlarged to about the same cross section of said pocket portions.

Claim 11

An adjustable eyeglass temple as claimed in claim 2 wherein the inner terminal end of said rearward member abuts the bottom of said channel when said pin is located in the outermost pocket portion of said slot remote from said inner terminal end of said rearward member.

Claim 12

An adjustable eyeglass temple as claimed in claim 2 wherein the cross section of said rearward member outboard of said slot in relation to said channel provides a close sliding fit and is reduced therebetween to permit flexing movement during movement of said pin between pocket portions without binding.
