<p>Articulation for use on knee or hip of femoral ortheses, being formed by two articulated flat-bars, with 90 degrees swing on the axle of articulation. The upper flat-bar (1) has a box (2) containing bolt (12) with a spiral spring (17). The lower flat-bar (8) has a yoke (10), held by a rivet (9). In the yoke is lodged the articulation axle (6) and a pin (11), supporting the bolt (12). The bolt is threaded (15) and there is a nut (16) to adjust the spiral spring force. On the other end of the bolt there is a semispherical washer (19), making end on the perforated wall (7) of the box (2). The perforated wall allows bolt (12) to pass through when articulation swings. The assembly mechanism is covered by two metallic lids (20). <IMAGE></p> |
