extending a second extendable leg to an extended position, the second extendable leg having a roller coupled to a bottom end of the second extendable leg; pivoting a handle around an axis created by a first fastener coupling the handle to the first extendable leg at a top end of the first extendable leg; pivoting the handle around an axis created by a second fastener coupling the handle to the second extendable leg at a top end of the second extendable leg, wherein the first and second extendable legs and the handle may contact one another longitudinally when the first and second extendable legs are in a retracted position; and securing cargo in physical communication with each of the first and second extendable legs by a band that couples to the first or second extendable leg at a bottom end of the first or second extendable leg and to the first or second extendable leg at a point distal from the bottom end such that the cargo maintains a relative position of the first and second legs with respect to each other. ### Claim 8 (depends on 7) The method of claim 7, further comprising the step of: coupling a cross member to a bottom end of the first extendable leg and to a bottom end of the second extendable leg. ### Claim 9 (depends on 8) The method of claim 8, further comprising the steps of: coupling a member to the bottom end of the first extendable leg, wherein the member thereby extends at an angle relative to a plane created by each of the first and second extendable legs so that the member is not substantially parallel to the plane. ### Claim 10 (depends on 7) The method of claim 7, further comprising the steps of: collapsing each of the first and second extendable legs; pivoting the handle around each of the first and second fasteners so that the first and second extendable legs are essentially parallel to each other and the bottom end of the first extendable leg is proximate to the top end of the second extendable leg. ### Claim 11 (depends on 10) The method of claim 10, wherein the length of the handle is approximately equal to the length of the first and second extendable legs and rollers coupled to the bottom ends of the first and second extendable legs when the first and second extendable legs are in a retracted position. ### Claim 12 A cargo transportation cart, comprising: a handle having pivotable coupling linkage on opposing ends of the handle; and a pair of extendable members adapted for receiving one or more bands for securing cargo to said extendable members, each extendable member having a roller coupled proximate to a bottom end of the extendable member and coupled to the handle at a top end of the extendable member according to the coupling linkage, whereby the handle and the extendable members may be pivotably extended to position the handle substantially transverse to at least one of the extendable members and may be pivotably collapsed to position the handle and the extendable members along a same axis. ### Claim 13 (depends on 12) The cart of claim 12, wherein the rollers coupled to each extendable member are positioned at an opposite end from each other when the handle and the extendable members are positioned along the same axis. ### Claim 14 (depends on 13) The cart of claim 13, wherein the length of the handle is approximately equal to the length of each of the extendable members and rollers when the extendable members are in a collapsed position. ### Claim 15 A collapsible cart for transporting cargo, comprising: first and second extendable legs, each extendable leg adapted for movement between an extended position and a collapsed position, and each extendable leg having a roller coupled proximate to a bottom end of the extendable leg; a handle coupled to the first extendable leg at a top end of the first extendable leg by a first fastener that permits the handle to pivot in relation to the first extendable leg about the first fastener, and to a second extendable leg at a top end of the second extendable leg by a second fastener that permits the handle to pivot in relation to the second extendable leg about the second fastener, wherein the handle may be pivoted about each of the first and second fasteners so that the first extendable leg, the handle, and the second extendable leg are oriented along a same axis; and one or more bands couplable to each of the first or second extendable legs at a first point on each of the first and second extendable legs and to a securing point distally located from the first point on the first or second extendable legs so as to secure cargo as a stabilizing member against the first and second extendable legs in the extended position. ### Claim 16 A cargo transportation cart comprising: a handle having opposing ends coupled pivotably to a pair of extendable legs, each of said extendable legs having a roller attached to a bottom end opposite said handle, each of said extendable legs being movable from a first position to a second position, the first position including each of said legs collapsed substantially parallel to said handle, oriented in opposing directions, and contacting one another longitudinally, and the second position including each of said legs extending laterally from said handle, and each of said extendable legs having a first length in the first position and a second length in the second position wherein the second length is greater than the first length, whereby a mass of cargo may secured to the cart adjacent the bottom ends of the legs such that the cart and cargo may be rolled from place to place upon the rollers while holding the handle. ### Claim 17 (depends on 16) The cart of claim 16, wherein said handle has a third length, and said first length and said third length are substantially the same. ### Claim 18 (depends on 16) The cart of claim 16, wherein said handle and said legs are oriented along the same axis when in an intermediate position between said first and second positions. ### Claim 19 A cargo transportation cart comprising: a pair of extendable members adapted for receiving one or more bands for securing cargo to said extendable members, each extendable member having a roller coupled proximate to a bottom end of the extendable member and a connection point at an opposite end of the extendable member, said pair of extendable members being movable from a first position to a second position, the first position including said extendable members being collapsed in substantially parallel and able to contact one another longitudinally, and the second position including said legs being extended and each of said extendable legs having a first length in the first position and a second length in the second position wherein the second length is greater than the first length; and a handle having opposing ends coupled pivotably to said pair of extendable legs at said connection points, whereby a mass of cargo may be strapped to the cart adjacent the bottom ends of the legs such that the cart and cargo may be rolled upon the rollers. ### Claim 20 (depends on 19) The cart of claim 19, wherein said handle has a third length, and said first length and said third length are substantially the same.
