Abstract

An eyeglass frame includes a lens frame, two temple-connecting arms having front ends disposed respectively and rotatably on left and right sides of the lens frame and each including a groove and a shaft hole, two temples having front ends disposed respectively and rotatably on rear ends of the temple-connecting arms, and a hinge assembly including two shaft seats respectively disposed on the left and right sides of the lens frame and each having a seat body and a seat hole, two shaft pins each inserted into aligned shaft hole and seat hole, two biasing members respectively disposed in the grooves of the temple-connecting arms, and two pressing members each abutting between one of the biasing members and the seat body of a corresponding shaft seat and capable of abutting against different surfaces of the seat body when each temple-connecting arm is rotated relative to the lens frame.

Dependent claims

An eyeglass frame comprising:

a lens frame;
two temple-connecting arms having front ends disposed respectively and rotatably on left and right sides of said lens frame, and rear ends opposite to said front ends, each of said temple-connecting arms including a first groove extending inwardly from said front end, and a first shaft hole formed in said front end and communicating transversely with said first groove;
two temples having front ends disposed respectively and rotatably on said rear ends of said temple-connecting arms, a rotating direction of each of said temples relative to the respective one of said temple-connecting arms being different from a rotating direction of each of said temple-connecting arms relative to said lens frame;
and
a hinge assembly including
two first shaft seats respectively disposed on said left and right sides of said lens frame, each of said first shaft seats having a first seat body inserted into said first groove of the respective one of said temple-connecting arms, and a first seat hole formed in said first seat body and aligned with said first shaft hole of the respective one of said temple-connecting arms,
two first shaft pins, each of said first shaft pins being inserted into said first shaft hole of the respective one of said temple-connecting arms and said aligned first seat hole,
two first biasing members respectively disposed in said first grooves of said temple-connecting arms and having front ends respectively facing said first seat bodies of said first shaft seats, and
two first pressing members, each of said first pressing members being disposed between and abutting against said front end of one of said first biasing members and said first seat body of a corresponding one of said first shaft seats, each of said first pressing members being capable of abutting against different surfaces of said first seat body of the corresponding one of said first shaft seats when each of said temple-connecting arms is rotated relative to said lens frame, each of said first biasing members generating different biasing forces according to different abutment positions of each of said first pressing members.
