<p>A snow chain device consisting of couples of elements that may be applied and fixed to any tyre, so as to obtain the complete covering of the same, comprising: - front and back loomes (1) and (2), reciprocally connected by snowbreak chains (3) provided with shock absorber springs (4), respectively provided with reference notches (5) and special bearings (6) that will facilitate the correct placing on the rim (C) of a tyre (P); - further snowbreak chains (7), provided with shock absorber springs (4) fixed onto the back loom (£) and such as to be hooked to the supports of the front loom (1) so as to completely surround said tyre (P); - supports (8), for hooking said snowbreak chains (7), connected, by means of the reciprocal threaded ends (9), to a central clamp (10) able to force the sliding thereof inside the guides (11) of the front loom (1), thus determining the retraction thereof and consequently determining the blocking of the whole structure onto said tyre (P), through putting into traction said snowbreak chains (7) linked thereto.</p> |
