Abstract: The invention is a locking mechanism for securing two solid wood, particle wood and fibreboard panels. It requires “no tools” to secure the panels, and the panels are secured by inserting a headed shank into a slotted plug receiver member. The purpose of the invention is to provide a fast and convenient way for securing two home or office furnishing panels together without the use of tools. The advantage of the invention is to present the end consumer with a truly “no tools” assembly of furnishing systems. The headed screw and slotted plug combination will initially be presented in a “no tools” line of furniture. Other possible applications include: store display fixtures, installation of blinds and drapery, and shelving.
