Abstract
A cart assembly adapted for manual, bicycle and/or motorized vehicle towing. Multiple frame sections are coupled to pivot between completely collapsed, partially open and completely open positions to facilitate, travel, storage and sleeping. A pair of axle plates support primary wheels to the framework and a drive axle between adjacent cross-brace arms. A handle frame section, saddle arms, truss arms, resilient spreader arms, auxiliary caster wheel, battery powered electric drive motor(s), fabric cover and/or hard cover mount to the framework. A resilient, reciprocating shock absorbing tow bar or tongue arm assembly provides flexibly resilient pieces to absorb travel shock between the cart and tow vehicle.
Claims20
A travel cart framework comprising:
- a) first and second frame sections, each of said first and second frame sections comprised of a plurality of interconnected members arranged in a planar configuration;
- b) first and second axle support members coupled to said first and second frame sections, wherein at least one of said first and second frame sections is coupled to pivot at said first and second axle support members between multiple predetermined relative angular orientations to each other, including a first position whereat said first frame section is collapsed onto and overlie said second frame section in parallel relation, a second position wherein the first frame section is pivoted in the range of 110° to 145° relative to the second frame section, and a third position whereat said first frame section is pivoted 180° to align co-planar with said second frame section;
- c) an axle mounted to said first and second axle plates and to first and second wheels mounted to rotate about opposite ends of said axle;
- and
- d) a tow bar secured to one of said first and second frame sections and including a coupler adapted to mount to a tow vehicle.

- a) first and second frame sections, each of said first and second frame sections comprised of a plurality of interconnected members arranged in a planar configuration;
- b) first and second axle support members coupled to said first and second frame sections, wherein at least one of said first and second frame sections is coupled to pivot at said first and second axle support members between multiple predetermined relative angular orientations to each other, including a first position whereat said first frame section is collapsed onto and overlies said second frame section in parallel relation and a second position whereat said first frame section is pivoted 180° to align co-planar with said second frame section;
- c) an axle mounted to said first and second axle support members and to first and second wheels mounted to rotate about opposite ends of said axle;
- d) a cover adapted to maintain a taught, tent-like condition when said first and second frame sections are deployed to said second position whereat said cover shelters an interior space overlying said first and second frame sections;
- and
- e) a tow arm secured for reciprocating movement relative to one of said first and second frame sections and including a coupler adapted to mount to a tow vehicle and further including a resilient member coupled to said tow arm to resiliently resist relative motion between said tow arm and the one of said first and second frame sections, whereby shock is absorbed and not transferred to said cart during towing.
