US Patent 9750999 Mobile fitness unit

The present application is directed to a mobile fitness unit in an automatically folding shipping container. The mobile fitness unit may be towed or air lifted into position, and unfolded to create a sturdy and flat platform for use. Frames may be extended out from the roof of the unfolded shipping container to form pull up bars and squat racks, or provide stable mounts for equipment such as lateral pull-down cables, punching bags, or other apparatuses. The mobile fitness unit may provide exercise positions for a dozen or more individuals simultaneously. After use, the frames may be collapsed and the sides of the container folded to seal the unit for movement.
