Abstract
A rack system of adjustable shelves has a simple and economical shelf assembly mechanism. A shelf is attached to its supporting vertical posts by placing each of the posts through an individually associated corner shelf socket. The shelf is kept in position by a plastic keeper which can be moved up and down the post to the desired height of the shelving. The keeper has a generally truncated pyramidal shape and at least one internal projection which fits into a dimple, recess, or notch formed in the post at the desired shelf height. The keeper has vertical slots that enables it to be squeezed together and to tightly wedge into the shelf socket and support the shelf on the corner post. The system can be adapted to both square and circular posts.
