Patent ID: 7695133

Claim:
Pair of spectacles ( 1 ) with interchangeable lenses ( 6 ), characterised in that: each lens frame ( 4 ) includes a slit ( 5 ) at the assembly area of the corresponding temple ( 3 ), the slit ( 5 ) extending from the inside of the lens frame ( 4 ) to the outside and thus delimiting two independent portions of the lens frame, it being possible to move the two portions apart to widen the lens frame ( 4 ) so that a lens ( 6 ) can be inserted or removed; and each temple ( 3 ) is connected to the corresponding lens frame ( 4 ) by means of a tenon ( 10 ), the tenon ( 10 ) comprising a first part ( 11 ) connected to the temple ( 3 ), used to make a rotating connection between the tenon ( 10 ) and the temple ( 3 ) along the general longitudinal axis of the temple ( 3 ), and a second part ( 12 ) engaged between the said lens frame ( 4 ) portions with the possibility of pivoting, the second part ( 12 ) having two dimensions in directions perpendicular to its pivot axis, namely a first dimension that can be in a first angular position of the tenon ( 10 ), in which the two portions of the lens frame ( 4 ), are not separated, and a second dimension in a second angular position of the tenon ( 10 ), in which the two portions of the lens frame ( 4 ) are separated sufficiently to widen the lens frame ( 4 ) so that the lens ( 6 ) can be replaced.
