Abstract
Abstract The combination of a child''s crib having a drop side and a trip lock for holding the drop side in raised position, that improvement which comprises a double lock safety means preventing the actuation of the trip lock in the absence of manually raising the drop side at least a small amount prior to actuating the trip lock. Thus, two separate actions are necessary before the drop side can be lowered.
