Abstract:
A scaffold joint assembly comprising:a post having a protrusion mounted thereto, said protrusion extending radially away from an outer surface of said post, said protrusion having an opening;a brace having a hook mounted thereto, said hook having a first surface facing and extending substantially parallel to said outer surface of said post, said hook having second surface opposite said first surface, said second surface slanting in an upward direction toward said outer post surface, said hook also having a third surface adjacent to said second hook surface and opposite and substantially parallel to said first hook surface; anda wedge having a first surface cooperating with said second hook surface to slide said wedge along said second hook surface in an upward direction when said hook is initially lowered from above into said opening, said first wedge surface slanting downwardly away from said outer surface of said post in a lower locking position of said wedge, said wedge having a second surface adjacent said first hook surface and extending in a substantially vertical direction in contact with said third hook surface in said lower locking position of said wedge, whereby a lower end of said wedge seats on said protrusion adjacent to said opening when introducing said hook into said opening, is displaced upwardly when said hook is further lowered into said opening, and then moves downwardly through said opening and pivots away from said post to firmly seat said wedge in said opening for blocking an upward movement of said brace.
