Abstract
A kit for repairing an eyeglass frame that has lost a hinge pin comprises a container with at least one hinge pin therein, the hinge pin being locally plastically deformable at one end thereof, and instructions for installing the hinge pin in the frame. The replacement hinge pin is deformable either by softening or melting with a small flame or other heat source, or alternatively has a soft end portion which is mechanically deformable. A user of the kit deforms a first end of the pin to form a first end with a diameter greater than the maximum body diameter of the hinge pin, inserts the pin into a hinge of the eyeglass frame, and then deforms a second end of the pin to form a second end with a diameter greater than the maximum body diameter of the hinge pin, so that an earpiece of the frame becomes pivotally secured by the pin.
Claims6
A method for repairing an eyeglass frame using a hinge pin having a first end with a diameter larger than a maximum diameter of a body of said pin, said maximum diameter being small enough to just fit in a hinge bore of said eyeglass frame, said hinge pin being plastically deformable by application of heat at a second end thereof, comprising the steps of:
- inserting said pin into a hinge of said eyeglass frame, and
- deforming said second end of said pin by heating to form a second deformed end with a diameter greater than said maximum diameter of said body of said hinge pin, wherein an earpiece of said frame becomes pivotally secured by said pin.
A method for repairing an eyeglass frame by using a hinge pin which is plastically deformable at first and second ends thereof by application of heat and has a maximum diameter small enough to just fit in a hinge bore of said eyeglass frame, comprising the steps of:
- deforming said first end of said pin by heating to form a first deformed end with a diameter greater than said maximum diameter of said hinge pin,
- inserting said pin into a hinge of said eyeglass frame, and
- deforming said second end of said pin by heating to form a second deformed end with a diameter greater than said maximum diameter of said hinge pin, wherein an earpiece of said frame becomes pivotally secured by said pin.
A method for repairing an eyeglass frame using a hinge pin having a first end with a diameter larger than a largest diameter of a body of said pin, said largest diameter of said body of said hinge pin being small enough to just fit in a hinge bore of said eyeglass frame, said pin further having a handling tab attached to said first end, and said pin being plastically deformable by application of heat at a second end thereof, comprising the steps of:
- inserting said pin into a hinge of said eyeglass frame,
- deforming said second end of said pin by heating to form a second deformed end with a diameter greater than said largest diameter of said body of said hinge pin, wherein an earpiece of said frame becomes pivotally secured by said pin, and
- separating said tab from said first end of said pin.
