US Patent 10575641 Shelving system, shelf unit, and method of assembling shelf unit

A cavity formed in a shelf can receive at least one bracket including at least one locking member. A locking member can engage an interior of the cavity. A shelf unit can be assembled by fastening a bracket to a substrate, inserting the bracket into an opening to the cavity, engaging the locking member with an interior surface of the cavity, and allowing the shelf to rest on the body of the bracket. The shelf can be removed from the bracket by disengaging the locking member from the interior of the cavity.
