ABSTRACT:
A modular floor for manual storage systems consists of floor modules joined to create a longitudinal path of any desired length for supporting a wheeled carriage for movement therealong. Each floor module comprises a pair of parallel rails that are independently vertically adjustable by means of leveling screws in transverse rail supporting beams. The ends of the rails are notched and tongue and grooved to provide vertical and horizontal alignment of the ends of adjoining rails. The modular floor includes sturdy and neat ramps extending transversely on each side thereof. The invention further includes an anti-tip device composed of plates secured to the carriages and having lips that slide along and cooperate with a member fixed to the modular floor to prevent the carriages from tipping in the direction of longitudinal movement.
