ECCENTRIC AND POLYCENTRIC ARTICULATED TENSIONING JOINT FOR ORTHOPEDIC BRACES

摘要

An eccentric and polycentric articulated tensioning joint (10) applied to an orthopedic brace with adjustable angular excursion placed in correspondence of body joints comprises two bars (13, 14) each hinged to a rotation pin (17, 18), wherein said rotation pins are constrained parallel to each other at a predefined distance, said two bars being connected to each other by means of respective semi-circular toothed profiles (25) present on each bar, so as to be set in synchronous motion relative to each other. Said two bars (13, 14) are associated with a respective pair of loop elements (15, 16), which are kinetically connected to said bars in such a way as to impart thereto the same rotational movements and partially transform them into relative translational movements along the longitudinal axes of each of the bars themselves, in order to effect linear movements of reciprocal distancing or nearing relative to the rotation centres thereof located on said pins (17, 18).
