Adjustable ergonomic brace

An ergonomic brace comprising:

• a first elongate strut;
• a second elongate strut;
• pivoting arrangements for intercoupling said first strut and said second strut;
• said pivoting arrangements having a center;
• and
• said pivoting arrangements including stop assemblies both for flexion and extension, including;
• a) a catch plate formed of a fiat arcuate disc having an arcuate opening and having stop recesses facing or opening toward the center of said pivoting arrangements;
• b) a movable stop pivoted at the center of the assembly and having an outwardly biased locking member for engaging said stop recesses, coupled to a release button which extends radially outward to the periphery of said pivoting arrangements;
• and
• c) said release button being movable inward to shift said locking member out of said stop recesses to permit angular adjustment of said stop;
• at least one of said struts having a flexion stop surface for engaging the flexion stop assembly;
• at least one of said struts having an extension stop surface for engaging the extension stop assembly;
• and
• an extension slidably engaging and extending over at least one of said first strut and second strut, wherein the extension includes a screw-in lock engaging one of a plurality of receiving holes in the at least one of said first strut and second strut;
• wherein the screw-in lock includes a rotating lever having a threaded post screwed to respective threads formed within the thickness of the extension and the extension defining an outer surface forming a ramped turn stop arranged to selectively engage the lever such that the rotating lever encounters rising resistance while moving up the turn stop in a first rotational direction until encountering a flat engagement face formed at one side of the turn stop to prevent further rotation of the rotating lever in the first rotational direction.
