Abstract
Abstract The improved latch is used for selectively securing and releasing a shelf in a storage unit. This improved latch includes a pivot leg, first and second connecting legs and a support leg. A spring or other biasing means is used between the pivot leg and a bolt of the hinge, and the latch is designed to rotate about the bolt of the hinge. The first connecting leg extends outside of the storage unit, and the second connecting leg extends through a respective side panel of the storage unit and connects the first connecting leg and the support leg. In operation, the upward moving shelf first pushes the latch out of the way and, after the shelf is moved completely upward, the latch springs back into position and the support leg holds the shelf firmly in position.
