A collapsible trailer and method for use of the same are disclosed. In one embodiment, the collapsible trailer includes a jointed lattice-work frame of scissor linkages which in the expanded position provide an open enclosure for transporting the load. Two orthogonally positioned collapsible crossbars span the open enclosure and releasably engage the lattice-work frame. A meshed netting is superposed to the collapsible crossbars and releasably coupled to the lattice-work frame. The collapsible trailer may be configured in a collapsed position for easy storage when not in use by removing the meshed netting, releasing the collapsible crossbars, and slidably collapsing the collapsible crossbars lengthwise and width wise in an accordion fashion.

What is claimed is: 1. A collapsible trailer comprising: a jointed lattice-work frame defining four sides, each of the four sides including a plurality of scissor linkages being configured in an expanded position and slidably expandable and collapsible in an accordion fashion between the expanded position defining an open enclosure and a collapsed position defining a closed enclosure; first and second wheel hub assemblies respectively disposed on first opposing sides of the four sides; first and second wheels respectively rotatably mounted to the first and second wheel hub assemblies; a first collapsible crossbar releasably engaged with the first wheel hub assembly and the second wheel hub assembly, the first collapsible crossbar spanning the open enclosure therebetween; a second collapsible crossbar orthogonally coupled to the first collapsible crossbar, the second collapsible crossbar releasably engaging second opposing sides of the four sides and spanning the open enclosure therebetween; a receptacle formed at an end of the second collapsible crossbar, the receptacle adapted to releasably accept an accessory selected from the group consisting of a trailer hitch and a tow bar; and a support platform defined by a meshed netting releasably engaging each of the four sides and spanning the open enclosure therebetween such that the support platform is superposed to the first and second collapsible crossbars. 2. The collapsible trailer as recited in claim 1, wherein the first opposing sides each further comprise three scissor linkage units pivotally connected in a series. 3. The collapsible trailer as recited in claim 2, wherein each of the three scissor linkage units further comprise a pair of equal length linkages pivotally connected at approximately mid-points by a pin. 4. The collapsible trailer as recited in claim 1, wherein the second opposing sides each further comprise two scissor linkage units pivotally connected in a series. 5. The collapsible trailer as recited in claim 4, wherein the second collapsible crossbar intersects and extends beyond an opening formed at the connection of the two scissor linkage units. 6. The collapsible trailer as recited in claim 5, wherein a portion of the second collapsible crossbar which extends beyond the opening further comprises an articulated joint that is adapted to fold the second collapsible crossbar upon itself. 7. The collapsible trailer as recited in claim 1, wherein the first wheel hub assembly further comprises: a vertical arm including an axle assembly coupling the first wheel thereto and a plurality of vertically spaced alignment holes therethrough; and a housing having a mating pin mounted therethrough, the housing adapted to slidably accept the vertical arm therein, thereby brining the housing and vertical arm into an adjustable mating engagement upon the alignment of one of the plurality of vertically spaced alignment holes and the mating pin. 8. The collapsible trailer as recited in claim 1, wherein the first collapsible crossbar further comprises first and second brackets including respective mounting pins, the mounting pins adapted for releasably engaging respective alignment holes associated with the first opposing sides. 9. The collapsible trailer as recited in claim 1, wherein the second collapsible crossbar further comprises first and second brackets including respective mounting pins, the mounting pins adapted for releasably engaging respective alignment holes associated with the second opposing sides. 10. The collapsible trailer as recited in claim 1, wherein the second collapsible crossbar is orthogonally coupled to the first collapsible crossbar by a cross support. 11. The collapsible trailer as recited in claim 10, wherein an extension of the first collapsible crossbar telescopes into the cross support. 12. The collapsible trailer as recited in claim 10, wherein the second collapsible crossbar rotatably turns in two locations toward an extension of the first collapsible crossbar. 13. The collapsible trailer as recited in claim 1, further comprising an auxiliary wheel assembly including a U-shaped auxiliary wheel frame adjustably secured to one of the first collapsible crossbar and the second collapsible crossbar, the U-shaped auxiliary wheel frame including an auxiliary wheel which extends from and is fixedly set at a level proximate to the first and second wheels. 14. The collapsible trailer as recited in claim 1, further comprising a motor for providing auxiliary rotary power to the first wheel. 15. A method for using a collapsible trailer, the method comprising: releasing a meshed netting from engagement with four sides of a jointed lattice-work frame of the collapsible trailer, the jointed lattice-work including a plurality of scissor linkages being configured in an expanded position, the meshed netting spanning an open enclosure defined by an interior of the jointed lattice work frame; releasing a first collapsible crossbar of the collapsible trailer from engagement with first opposing sides of the four sides, the first collapsible crossbar spanning the open enclosure; releasing a second collapsible crossbar of the collapsible trailer from engagement with second opposing sides of the four sides, the second collapsible crossbar spanning the open enclosure; collapsing the first and second collapsible crossbars; removing the first and second collapsible crossbars from the open enclosure; and slidably collapsing the four sides of the jointed lattice work frame in an accordion fashion to configure the collapsible trailer in a collapsed position. 16. The method as recited in claim 15, wherein releasing a first collapsible crossbar from engagement further comprises disengaging a mounting pin adapted to releasably engage respective alignment holes associated with a bracket of the first collapsible crossbar and the jointed lattice-work frame. 17. The method as recited in claim 15, wherein removing the first and second collapsible crossbars from the open enclosure further comprises: telescoping a first extension of the first collapsible crossbar into a cross support disposed at an orthogonal intersection of the first and second collapsible crossbars; and rotatably turning the second collapsible crossbar toward a second extension of the first collapsible at two separate joints. 18. A collapsible trailer comprising: a meshed netting spanning an open enclosure defined by an interior of a jointed lattice work frame with means for releasing the meshed netting from engagement with four sides of the jointed lattice-work frame, said frame including a plurality of scissor linkages being configured in an expanded position; a first collapsible crossbar spanning the open enclosure with means for releasing the first collapsible crossbar from engagement with first opposing sides of the four sides; a second collapsible crossbar spanning the open enclosure with means for releasing the second collapsible crossbar from engagement with second opposing sides of the four sides; means for collapsing the first and second collapsible crossbars; means for removing the first and second collapsible crossbars from the open enclosure; and means for slidably collapsing the four sides of the jointed lattice work frame in an accordion fashion to configure the collapsible trailer in a collapsed position. 19. The collapsible crossbar as recited in claim 18, wherein the means for releasing a first collapsible crossbar from engagement further comprises means for disengaging a mounting pin adapted to releasably engage respective alignment holes associated with a bracket of the first collapsible crossbar and the jointed lattice-work frame. 20. The collapsible crossbar as recited in claim 18, wherein the means for removing the first and second collapsible crossbars from the open enclosure further comprises: means for telescoping a first extension of the first collapsible crossbar into a cross support disposed at an orthogonal intersection of the first and second collapsible crossbars; and means for rotatably turning the second collapsible crossbar toward a second extension of the first collapsible at two separate joints.
