Abstract
A spectacle frame including a first part, at least a second part, a joining part joining the second part to the first part allowing to fold and unfold the second part relative to the first part so that the second part be movable between respective closed position and open position, at least an electrical wiring arranged through the joining part to allow an electrical connectivity between the first part and the second part, wherein the joining part is elastically deformable with curvature radius values higher than a predefined minimum curvature radius value.
Claims16
A spectacle frame comprising:
- a first part that is a front part;
- a second part that is a temple;
- a joining part joining the second part to the first part allowing to fold and unfold the second part relative to the first part so that the second part be movable between respective closed position and open position;
- and
- at least an electrical wiring arranged through the joining part to allow an electrical connectivity between the first part and the second part,
- wherein the joining part is elastically deformable with curvature radius values higher than a predefined minimum curvature radius value,
- wherein the joining part is made of a single material, and
- wherein the joining part comprises a bridge part, an abutment part and a sliding part forming first and the second stop devices,
- the bridge part being integral to the first part and to the second part to create a bridge between the first part that is the front part and the second part that is the temple, said bridge part being flexible,
- the abutment part being integral to the first part and being less flexible than the bridge part,
- the sliding part being integral to the second part and being less flexible than the bridge part, and
- the sliding pan being located between the bridge part and the abutment part, the bridge part being located facing the center of curvature of the folding, in order that when the second part is folded, the sliding part bears and slides on the abutment part and creates a strength opposed to the folding.
A method for manufacturing a spectacle frame including a first part that is a front part, a second part that is a temple, a joining part joining the second part to the first part allowing to fold and unfold the second part relative to the first part so that the second part be movable between respective closed position and open position, and at least an electrical wiring arranged through the joining part to allow an electrical connectivity between the first part and the second part, wherein the joining part is elastically deformable with curvature radius values higher than a predefined minimum curvature radius value, comprising:
- generating the spectacle frame using a three-dimensional printing process for at least one part of the spectacle frame,
- wherein the joining part is made of single material, and
- wherein the joining part comprises a bridge part, an abutment part and a sliding part forming first and the second stop devices,
- the bridge part being integral to the first part and to the second part to create a bridge between the first part that is the front part and the second part that is the temple, said bridge part being flexible,
- the abutment part being integral to the first part and being less flexible than the bridge part,
- the sliding part being integral to the second part and being less flexible than the bridge part, and
- the sliding part being located between the bridge part and the abutment part, the bridge part being located facing the center of curvature of the folding, in order that when the second part is folded, the sliding part bears and slides on the abutment part and creates a strength opposed to the folding.
