ABSTRACT:
A novel structural locking apparatus and method which utilizes corrugated fiberboard components entirely to join structural elements into a finished product of high durability.
The locking apparatus is specifically designed for and applied to bookshelving units but may readily be applied to larger or smaller products wherein it is necessary to join one wall surface to another.
A unique design allows all components to be factory pre-cut so that the apparatus components may be readily assembled by personnel unskilled in the art of furniture assembly.
The design allows the bookshelf kit components to be shipped flat for reduced transportation costs.
