OVERHEAD TRACK HIGH DENSITY STORAGE SYSTEM WITH CENTER AND SIDE GUIDE ROLLERS AND CASTER LOCK ALIGNMENT CLIP

摘要

An overhead track high density storage system is formed by connecting an ove rhead track to the top posts of stationary storage units, thereby holding the track abov e a horizontal support surface, such as the floor. Movable storage units, such as shelves mounted o n casters, are positioned between the stationary storage units. Guide roller means attached to the top of the movable storage units are received within the track so that translational mo vement of the movable storage unit is confined to a path defined by the track. The guide r oller means include a center guide roller and at least one side guide roller mounted for rotationa l movement to a guide roller support channel. Each caster is locked into a directional position to prevent swiveling with a single caster alignment clip, which includes upstanding fingers defin ing a slot therebetween. The slot of the clip engages a portion of the movable storage unit, such as a support rod in a truss of a wire shelf that forms a part of the movable storage unit.
