Abstract
A knee joint coupling comprises a pair of similar U-shaped links each having a base and two parallel legs extending perpendicularly from the base. One of the legs of each link has a hole through it and the other leg has a pin extending from it in the direction either toward or away from the hole. When the pin of each link is fitted into the hole of the other link, there is assembled a knee-joint type of coupling due to the pivoting action of the pins in the holes. The links may be held assembled by means such as screw members inserted through the bases and into the region between the legs of the two links. Alternatively one of the links may have its base fixed to one member while the other link is fixed to the other member in which case the two members are pivotable as a door hinge or the like relative to each other.
