Abstract
An underfloor storage system is disclosed. The storage system comprises a frame with a storage box and at least one raise/lower mechanisms to raise and lower the storage box. A raise/lower mechanism include at least one winch driven pulley system. The storage box includes a floor. Raising the storage box provides access to underfloor storage. In a preferred embodiment, each winch driven pulley system provides an ideal mechanical advantage of 4 and includes an additional pulley which is configured to pivot relative to the winch and thereby adjust the orientation of the pulley to the winch as the line tracks across the winch during wind up or let out of the line.
