Abstract
An orthopedic device, first and second struts, and a range-of-motion limiting pivot assembly connecting to the first and second struts. The pivoting assembly having an engagement member linked to a tab disposed and arranged for pulling radially outward away from a central axis of the pivoting assembly for adjusting the range of motion of the pivoting assembly.
Claims18
A pivot assembly for an orthopedic device having a central axis, comprising:
- a cover;
- a first plate disposed within the cover, the first plate having a plurality of engagement surfaces disposed along an outer periphery of the first plate;
- an arcuate channel defined by an inner peripheral surface of the cover and the first plate, the arcuate channel radially spaced from and coaxial with the central axis;
- a first pivot stop having a carriage and a tab attached to a body that slidably inserts into the carriage and is arranged to move parallel or is axial with an axis of the carriage, and an engagement member slidably disposed within the carriage and transversely extending from the body to protrude through a slot formed by the carriage, the engagement member being arranged to engage the engagement surfaces of the first plate;
- wherein the carriage extends over a first plate and includes at least one flange arranged to be received into the arcuate channel;
- wherein the engagement member is elastically biased radially inward relative to the carriage and the central axis to engage one of the plurality of engagement surfaces of the first plate to lock rotation of the first pivot stop, and wherein radially outward movement of the tab moves the body radially outward relative to the carriage and disengages the engagement member from the one of the plurality of engagement surfaces to unlock rotation of the first pivot stop from the first plate;
- wherein the first plate is formed as a substantially solid integrated piece omitting an arcuate slot or arcuate cutout portions.

A pivot assembly for an orthopedic device having a central axis, comprising:
- a first pivot stop having a carriage and a tab attached to a body that slidably inserted into the carriage and arranged to move parallel or is axial with an axis of the carriage, and an engagement member slidably disposed within the carriage and extending from the body to protrude through a slot formed by the carriage, the engagement member being arranged to engage engagement surfaces of the pivot assembly;
- a lock arranged to fit over the tab and a portion of the carriage to prevent outward movement of the tab relative to the carriage and snap to at least one angled corner oriented downwardly and outwardly relative to the outward movement of the tab and defined by the carriage to arrest the outward movement of the tab relative to the carriage;
- wherein the lock forms at least one latch to engage the at least one angled corner of the carriage, the at least one latch oriented at an angle and inwardly relative to the at least one angled corner to mate therewith;
- wherein the lock has first and second arms having a width therebetween that is smaller than a maximum width of the tab in an original predetermined shape prior to being installed over the tab, the first and second arms each have one of said at least one latch directed inwardly and opposite one another on an opposing one of said first and second arms, the latches of the respective first and second arms spanning said width between the first and second arms, the first and second arms are arranged to deflect over the tab to snap inwardly against and under first and second angled corners of the at least one angled corner and leading to an underside of the carriage once the lock is fully placed over the tab and carriage, once snapped against the underside of the carriage, the lock returns to its original predetermined shape.
