Abstract
An eyeglass frame wherein one of the components such as the temples, the bridge and/or the connection bar between the eyewires is made of a shaped memory alloy which is able to regain its initial shape by simple heating after having undergone a permanent deformation and a lower temperature.
Claims21
A metal eyeglass frame comprising:
- one of a temple, a bridge, and a bar, made of a monocrystalline shape memory alloy, said alloy being selected from one of a group of alloys based on Cu and Fe.
A metal eyeglass frame comprising:
- one of a temple, a bridge, and a bar, made of a shape memory alloy, said shape memory alloy being selected from one of a group of alloys consisting of Fe--Mn--Si, Fe--Mn--Cr, and Fe--Mn--Cr--Si.
An eyeglass frame having at least a portion thereof fabricated from a monocrystalline shape memory alloy, said alloy being selected from one of a group of alloys based on Cu and Fe.
A metal eyeglass frame comprising:
- one of a temple, a bridge, and a bar, made of a shape memory alloy, said shape memory alloy being selected from one of a group of alloys consisting of Cu--Al--Cu, Cu--Al--Ni, Cu--Al--Be, and Cu--Al--Mn.
