Abstract
A one-piece, composite eyewear article including a frame having two temples, a top bar and two hinges, the entire frame composed of a single integral piece of solidified thermoplastic consisting of a polymer, a lens situated against, and extending across, the top bar, the lens composed of a single integral piece of optical grade cured liquid silicone rubber consisting of a dimethyl polysiloxane polymer thermoset, and wherein the frame and lens are molded via a two-material molding process, such that the lens auto-adheres to the frame during curing.
Claims20
A one-piece, composite eyewear article, comprising:
- a) an eyewear frame comprising of two temples, a top bar and two hinges, the entire frame composed of a single integral piece of solidified thermoplastic consisting of a polymer;
- b) a lens situated against, and extending across, the top bar, the lens composed of a single integral piece of optical grade cured liquid silicone rubber consisting of a dimethyl polysiloxane polymer thermoset;
- and
- c) wherein the frame and lens are molded via a two-material molding process, such that the lens auto-adheres to the frame during curing.
A composite eyewear article, comprising:
- a) an eyewear frame comprising of two temple stubs, a top bar, a nosepiece and two hinges, the entire frame composed of a single integral piece of solidified thermoplastic consisting of a polymer;
- b) a lens situated against, and extending across, the top bar, the lens composed of a single integral piece of optical grade cured liquid silicone rubber consisting of a dimethyl polysiloxane polymer thermoset;
- c) wherein the frame and lens are molded via a two-material molding process, such that the lens auto-adheres to the frame during curing;
- and
- d) a pair of separately molded temple arms configured for removable coupling with the two temple stubs.
A one-piece, composite eyewear article, the article prepared by a process comprising the steps of:
- a) providing a mold having a first void defining an eyewear frame comprising of two temple stubs, a top bar and two hinges, and a second void defining a lens situated against the top bar and extending across the top bar;
- b) injecting the first void in the mold with a thermoplastic consisting of a liquid polymer, so as to produce said frame as a single integral piece;
- c) injecting the second void in the mold with optical grade silicone rubber consisting of a liquid dimethyl polysiloxane polymer thermoset, so as to produce said lens as a single integral piece;
- d) allowing a predefined period of time to pass, wherein during said period of time, the lens auto-adheres to the frame during curing;
- and
- e) removing the one-piece, composite eyewear article from the mold.
A composite eyewear article, comprising:
- a) an eyewear frame comprising of two temple stubs, a top bar, a nosepiece and two hinges, the entire frame composed of a single integral piece of cured liquid silicone rubber consisting of a dimethyl polysiloxane polymer thermoset;
- b) a lens situated against, and extending across, the top bar, the lens composed of a single integral piece of optical grade cured liquid silicone rubber consisting of a dimethyl polysiloxane polymer thermoset;
- c) wherein the frame and lens are molded via a two-material molding process, such that the lens auto-adheres to the frame during curing;
- and
- d) a pair of temple arms configured for removable coupling with the two temple stubs, each temple arm composed of a single integral piece of solidified thermoplastic consisting of a polymer.
