  • Patent number: 9307846
    Abstract: Provided herein are articles useful for carrying and toting various articles, in addition to persons. One of the members of a frame assembly having two members hingedly connected to one another is secured to a shoulder harness, enabling the articles to be worn on the back of a user. A frame member having a seat or cargo grill or other framework is pivotable to an extended position, the pivotal travel of which is limited by the configuration of a loop and its orientation with respect to its contact with the other frame member, which contact simultaneously serves to provide force for supporting mass present on the seat or cargo grill or other framework. The frame assembly members are contoured to conserve space when stored, when the frame members are in a retracted position with respect to one another.
