Abstract
An improved locking apparatus for a slidably mounted product carrying shelf in a helical coil vending machine. Each shelf includes a front roller normally retained in a front stop. The locking apparatus comprises a pivotably mounted lock member mounted above the front stop of each shelf. The lock member has a lock surface which in a first or normal position of the lock member prevents the front roller from being removed from the front stop to lock the shelf in position in the vending machine. The lock member may be rotated to either a second or third position where the lock surface clears the front roller to allow the shelf to be slid out of the vending machine. The lock member is counterweighted such that it will remain in its third position to allow an operator to completely remove the shelf from the vending machine.
