Abstract:
1. A mobile storage unit configured to operate at an angled position and an upright position comprising: a. a rigid frame; b. a pair of wheels coupled to the rigid frame and having an extended position and a retracted position; c. at least one wheel mechanism for retracting the pair of wheels into the retracted position when a downward force is applied to the rigid frame in an upright position, wherein the wheel mechanism further comprises a pair of biasing elements, each of the pair of biasing elements coupled to a respective one of the pair of wheels for automatically biasing the pair of wheels in the extended position by pulling the pair of wheels in a direction away from a top of the rigid frame such that at least a portion of each of the pair of wheels is below the rigid frame thereby allowing the wheels to roll under the rigid frame; and d. at least one supplemental support positioned above the ground when the pair of wheels are in the extended position, wherein the supplemental support touches the ground when the pair of wheels is in the retracted position.
