<p>FIELD: construction.SUBSTANCE: block for a mobile cantilever gate, including a support structure with a bearing element, having two pairs of support wheels, which freely rotate along axes, mainly, horizontal, in a rail, and a guide wheel, freely rotating along in general a vertical axis in a rail. The bearing element is formed of two profiled plates, which are rigidly and in parallel connected to each other by means of fixtures, each of which comprises: two first holes combined with the appropriate first holes of the other profiled plate, which form together two first seats for installation of the first support bases with the possibility of rotation of two pairs of support wheels; a concavity above the upper profile of the profiled plate, combined with a similar cavity of the other profiled plate, which form together the second seat for a guide wheel, installed as capable of rotation on the second support elements; a convexity stretching from the upper profile of the profiled plate, corresponding to the cavity and having a groove, opposite to the groove of the other profiled plate. Together they form a cavity in a combination with the second seat for the reception of the second support elements of the guide wheel.EFFECT: improved design.7 cl, 7 dwg</p> |
