Abstract: A device is provided for releasably connecting together two elements of an orthosis or prosthesis. The device includes two plate members each attachable to a different orthotic element and a slider plate that is movable between a first released position and a second locked position. The device also may include a stop to secure the slider plate in the locked position.

Abstract: A coupling, for example, for an orthotic brace has a cam member with a first planar bearing face journalled for rotation on a planar bearing surface of a first coupling portion, and a second planar bearing face inclined to the first face and journalled to rotate relative to a planar bearing surface of a second coupling portion. A clamping device urges the faces and surfaces together to exert a frictional reaction retaining the cam member in a selected rotational position and retains the coupling portions rigidly opposed towards the cam member.

Abstract: A mechanical joint for pivotally connecting two members, particularly members of an orthopedic or orthotic device, to limit the degree of pivotal movement between the members and precisely and easily adjust the position of limited pivotal movement between the two members.
