Spectacles frame side with changeable curvature
View Patent ↗The side ( 1 ) includes an articulation front end ( 2 ) adapted to be articulated to a frame front face via a hinge ( 5 ) and a free rear end ( 3 ), a core ( 6 ) extending inside the side. One of the front and rear ends of the core ( 6 ) is anchored ( 8 ) in one of the front and rear ends of the side and the side includes, fixed to it, driving and shaping means ( 11, 16 ) for driving the other of the ends of the core, movably mounted in the other of the ends of the side and to deform the side and thus to modify its contour and curvature.
1. A spectacle frame side including an articulation front end adapted to be articulated to a frame front face via a hinge and a free rear end, a core extending inside the side, characterized in that one of the front and rear ends of the core is anchored in one of the front and rear ends of the side and the side includes, fixed to it, driving and shaping means for driving the other of the ends of the core, movably mounted, to move in the other of the ends of the temple and to deform the side and thus to modify its contour.
2. A frame side as claimed in claim 1 , wherein the rear end of the core is anchored in the free rear end of the side, the driving means being disposed in the articulation front end of the side.
3. A frame side as claimed in claim 1 , wherein the rear end of the core is movably mounted in the free rear end of the side, the driving means being disposed in the free rear end of the side.
4. A frame side as claimed in claim 1 , wherein the mobile end of the core is externally threaded to cooperate with an internally threaded sleeve of the driving and shaping means of the side also including a thumbwheel for driving the sleeve in rotation.
5. A frame side as claimed in claim 1 , wherein the core extends in a channel formed in the side and along which are provided spaced shaping bridges under which the core extends.
6. A frame side as claimed in claim 1 , wherein there is provided at least one stiffened local area preventing modification of contour in one plane to enable it orthogonally to that plane.
