  • Expandible trailer
    Publication number: 20060145499
    Abstract: An expanding trailer has two nesting expandable modules. By using hinged arms operating from a central rotating axis, the two modules are extended simultaneously. Previously a problem was that the modules on either side extend unevenly which causes balance problems. This design permits two opposed modules to extend evenly and simultaneously. Also a mechanism is provided to level the floor of the extended modules with the central floor once extended.
