Abstract
A joint structure for connecting together shelves in a modular shelf assembly includes first and second, coplanar, abutting shelves. A hole is formed through the shelves with one-half of the hole being formed in each shelf so as to complete the hole when the shelves are abutting each other. The shelves are sandwiched between first and second vertically extending supports which are connected together by fastening means extending through the hole in the shelves. Formed in the upper side of the shelves is an annular recess concentric with the hole and having an inverted cup-shaped bottom surface. An annular boss is formed on the end of the upper support and includes a cup-shaped end surface sized to fit within the recess. When the fastening means is tightened between the supports, the boss telescopes into the recess with the end surface seating against the bottom surface of the recess, camming the shelves together in abutting edgewise engagement and holding the shelves against edgewise separation without the end surface of the upper support engaging the upper surface of the shelves.
