To manufacture rimless eyeglasses without soldering the parts and to make the
assembling easy, a bridge and two joint pieces are provided by cutting or punching
a piece of metal sheet into a required flat shape. The bridge comprises a crossbar
having two pin-like extensions, two press-fitting extensions and two leg extensions
integrally connected to the opposite ends of the crossbar. The pin-like extensions
have saw-tooth indentations formed on their surfaces, and the leg extensions end
with hooks for fixedly holding nose pads. Each joint piece has a pin-like extension
with saw-tooth indentations formed on its surface and a press-fitting extension.
Each lens has a through hole and a notch made on either side. Each through hole
has a flanged sleeve press-fitted therein, and the pin-like extensions of the bridge
and joint pieces are inserted into the flanged sleeves in the through holes of
the lenses, and the press-fitting extensions of the bridge and joint pieces are
inserted into the notches of the lenses.
