  • Patent number: 7850185
    Abstract: A carrying trailer for use with bicycles includes a spine, a plurality of branch members and a wheel. The spine has a connecting portion at one end thereof which is adapted to couple to a bicycle. Each branch member has a ring and a supporting arm. The ring is rotatably mounted around the spine. One end of the supporting arm is fixed to an outer radial surface of the ring and the other end thereof extends away from an axis of the ring, with the supporting arm extending in a radial direction of the ring. The wheel pivotably couples to the other end of the spine. Consequently, positions of the branch members on the spine can be adjust to form a loading plane, or to stack the supporting arms of the branch members up at the same side of the spine for reducing storage space.

The adjusting modules mounted at two opposite sides of the carrying frame respectively. Each adjusting module includes a pivoting member pivotably coupled to an corner of the carrying frame, an adjusting member movably mounted on the carrying frame to move close to or away from the pivoting member and a connecting bar with two ends thereof respectively fixed to the adjusting member and one end of the pivoting member. The two wheels are coupled to the other ends of the pivoting members of the two adjusting modules respectively. Consequently, positions of the wheels relative to the carrying frame are adjustable through the adjusting modules, so that the bicycle trailer can be adapted as a baggage barrow when separated from a bicycle.
