Mechanical joint construction

摘要

An improved mechanical joint construction for pivotally interconnecting two members, particularly members of an orthopedic or orthotic body appliance, to limit the degree of pivotal movement between the members and adjustably control the position of limited pivotal movement of the two members; comprising first securement components for attachment to a first appliance member to be interconnected and presenting a generally flat planar surface with pivot pin extending outwardly from the surface and a protrusion on the surface spaced radially from the pivot pin; second securement components for rigid attachment to a second appliance member to be interconnected and comprising an inner peripherally serrated plate with central opening for receipt of the pivot pin to support the inner plate for rotation thereon, an arcuate slot in the inner plate spaced radially from the opening therein and receiving the protrusion for movement between ends of the slot to limit relative rotational movement of the inner plate on the pivot pin, and an outer member having a portion for attachment to the second appliance member to be interconnected and a serrated opening therein for surrounding intermeshing engagement with the peripheral serrations on the inner plate to fix the outer member against relative rotation with respect to the inner plate, and a removable cover plate for securing the inner plate and outer member in adjustable intermeshed engagement on the pivot pin to rotate within limits defined by movement of the protrusion in the inner plate slot.
