Abstract
A slippage preventing locking furniture fastener, method of making same, and a joint structure which includes a flexible locking clip and shouldered screw. The clip has a raised central portion having an inclined slot therein which is connected to a furniture piece by securing flanges. An internal locking flange extends at an upward angle toward the raised central portion and terminates below the slot, adjacent the head of a shouldered screw received in a seating area. The free end of the locking flange is wider than the slot to prevent the locking flange from passing through the slot or allowing the joint to loosen, even when substantial force is applied to the joint including the clip. A method for forming the clip is also disclosed including cutting a configured tab in a metal blank and bending the blank. The bending includes positioning the tab as a locking flange with its free end adjacent a narrower slot portion in a raised central portion. The slot is defined by at least a portion of the outline of the configured tab.
