  • Knock-down fittings
    Patent number: 4634309
    Abstract: A knock-down fitting to hold together two panels at right-angles to one another comprises a body having projections extending from one side and a peg which is received in a bore in the body. One end of the peg and each projection of the body has barb formations to engage holes pre-drilled in the panels.In accordance with the invention the other end of the peg received in the bore is toggle-shaped and has a waist engaged on opposite sides by the arms of a bifurcated clip. By acting on the cam surface provided by the waist the clip draws the peg into the bore in the body but the toggle shape of the inner end of the peg allows a degree of lateral tolerance to compensate for minor inaccuracies in the positioning of the holes in the panels.
