<p>There is described a pair of spectacles with interchangeable arms (6), comprising a front frame (2) with opposed lateral lugs (7) for the hinged pivoting of the respective lateral arms (6), a device for the removable coupling of each arm (6) to the frame (2), the device comprising a first and a second coupling element (8, 9), engaged in each other so as to be slidable from and towards a position of mutual retention, the elements being configured for quick disengagement from this position, the first coupling element (8) being intended for the hinged connection to the respective lug (7) of the frame (2), and the second element (9) comprises a seat (12) which is provided in the corresponding arm (6) and which can be slidingly engaged by the first element (8), resiliently flexible retaining means being provided between the coupling elements (8, 9) of each arm (6) to fix these elements to each other in a removable manner, by means of a snap-fitting coupling. The first coupling element (8) comprises a strip- shaped body (11) with a first and a second branch (13, 14) of the strip extending from a common portion (15) and having their predominant longitudinal extents in directions parallel with each other, the branches (13, 14) being spaced apart and extending in a first direction (X) substantially perpendicular to the strip plane (P) and in a second direction (Y) substantially parallel with the strip plane (P), in such a manner that the branches (13, 14) of the strip can engage the seat (12) in the arm (6) by bearing against opposing inner surfaces (12a, b; 12c, d) of the seat (12) in both the first direction (X) and the second direction (Y), as a result of a resilient stress created in the branches (13, 14) of the strip in these directions (X, Y).</p> |
