US Patent 10342335 Shelf lock assembly

Present embodiments relate to a shelf system for an appliance which has a lock device that may be easily retrofitted to render the shelves locked in position rather than removable and/or adjustable. The lock system inhibits rotation of the shelf in a direction normally required for removal of the shelf and movement thereof. The lock may be formed integrally or may be formed separately of the shelf support or bracket and may be connected to the bracket once the shelf is in a desired position in order to lock the shelf in place.
