Knuckle Joint Hinge

is a similar type of joint to the above, and is called the knuckle joint. This arrangement of hingeing allows the table leg to swing in an angle of 180 degrees and is much neater in its appearance. It is often used to connect a movable table leg to the framing, where it is necessary for the table leg and rail to swing outwards and support a drop leaf. The pivot is formed by a piece of 1⁄8-in. or 1⁄4-in. round iron rod running through the centre of the joint.
