ABSTRACT:
A hinge assembly is provided for an orthopedic brace having a rotatable hinge and a detent mechanism to automatically, yet releasably, lock the hinge in a fixed position of rotation. The hinge includes two rotatably attached members and the detent mechanism includes an indentation formed in the attached end of one member and a block pivotally mounted on the other member. The block has a locking projection that is biased toward the indentation and cooperates therewith to provide three positions of operation, a locked position, a release position, and an activated position. In the locked position, the locking projection fittingly engages the indentation, thereby substantially preventing rotation of the hinge. The release position displaces the locking projection a radial distance away from the indentation, thereby permitting the hinge to rotate freely. In the activated position, the block disengages the indentation and maintains an angular distance therefrom so that the detent mechanism does not obstruct rotation of the hinge, but enables automatic repositioning of the hinge assembly to the locked position whenever the locking projection and indentation angularly realign.
