Abstract:
Eyewear comprising:a first lens and a second lens, each lens having a hole with a hole diameter and an inner surface, each lens having a circumferential surface; and a first temple connected to the first lens and a second temple connected to the second lens, each temple including a positioning member, a connection member, and a hinge, the positioning member coupled to the connection member by the hinge, the connection member of each temple including: a threaded pin with a pin diameter and threads, the threaded pin extending into the lens hole of the one of the first and second lenses to which the temple is connected; an expandable sleeve being a longitudinal hollow cylinder having an inner sleeve diameter, an outer sleeve diameter, an outer sleeve surface and first and second ends, the first end having an opening with an inner diameter greater than the pin diameter, the second end having an opening with a second inner diameter, the threaded pin extending through the first end opening and within the expandable sleeve; and a tapered cap having an interior, a first end portion with an opening providing access to the interior, the interior having a threaded inner surface, the threaded pin extending into the interior of the tapered cap through the opening of the tapered cap, the tapered cap being threaded onto the threaded pin, the first end portion having a first exterior surface portion with a first outer diameter smaller than the second inner diameter of the expandable sleeve, the tapered cap having a second portion having a second exterior surface portion with a second outer diameter greater than the first outer diameter, the tapered cap extending at least partially within the expandable sleeve, the tapered cap having an exterior surface extending between the first and second exterior surface portions with an outer diameter increasing from the first outer diameter of the first end portion to the second outer diameter of the second portion to increasingly frictionally engage the tapered cap with the expandable sleeve and radially outward expand the outer sleeve diameter of the expandable sleeve as the tapered cap is being threaded onto the threaded pin, the second outer diameter of the tapered cap being sized to radially expand the expandable sleeve to increase the outer sleeve diameter sufficiently to frictionally engage the outer sleeve surface with the inner surface of the lens hole within which positioned to securely connect the connection member with the one of the first and second lenses to which the temple is connected.
