Patent ID: 10585298

Abstract:
A hinged connection between first and second members (24, 25) which makes use of a fixation pin (1). The fixation pin (1) has a first configuration which enables the pin to be inserted through a first hole in a first member (24), through an aligned intermediate hole in the second member (25) and through an aligned second hole in the first member (24). The fixation pin (1) does not have a screw thread on its exterior surface. The fixation pin (1) after it has been inserted is subject to a treatment which changes it to a second configuration, or the fixation pin spontaneously changes, while it is being inserted through the holes or immediately thereafter, to a second configuration. In the second configuration, part or all of the fixation pin contacts the wall of at least one of the holes, so that the first and second members are connected together at a hinged connection. The invention is particularly useful when the hinged connection is part of an eyeglass assembly, wherein the temple member or the frame member is the first member (24) and the other is the second member (25).
