<p>An elastic hinge device for connecting the arms (3) to a front piece (2) of spectacles, the device comprising a bar (10) which can be pivoted on a block (8) of the front piece (2) and can be slidably associated with the arm (3), at least one elastic return means (18) acting between the arm (3) and the bar (10) to push the bar towards the block, a box-like support (13) for housing and at least partially guiding the bar (10) and the elastic return means, bearing means (16, 17) being provided in said support (13) and on the bar (10) to bear against the opposing ends of the elastic return means, in such a way that the bar (10) is slidably associated with the support (13), in opposition to the action of the elastic return means (18), and a cover element (21) for closing the box-like support (13) and consequently retaining the bar (10) in the support. The elastic return means comprises a body (18) of elastomeric material which can be at least partially housed in a cavity (11) provided in a portion of the bar (10) engaged slidably in the box-like support (13).</p> |
