A folding cart (20) includes a frame (22) having a first extendable leg and a second extendable leg. A bag support (30) connects the first extendable leg with the second extendable leg and defines a first plate (44) adjacent the first extendable leg. A second plate (46) is defined on the bag support
A folding cart (20) includes a frame (22) having a first extendable leg and a second extendable leg. A bag support (30) connects the first extendable leg with the second extendable leg and defines a first plate (44) adjacent the first extendable leg. A second plate (46) is defined on the bag support (30) adjacent the second extendable leg. A vertical hinge (48) rotatably connects the first plate (44) with the second plate (46) such that the first plate (44) can rotate relative to the second plate (46) about a bag support (30) axis of rotation such that the cart (20) is can be folded when not in use.

The rolling cart of claim 1, further including an auxiliary leg pivotally connected to the first plate, the auxiliary leg being arranged to pivot away from the hag support such that the rolling cart is capable of standing upright at an angle relative to a flat surface. 5. The rolling cart of claim 4, further including: a hollow opening formed along a length of the auxiliary leg; anda telescoping extension lockingly disposed within the hollow opening. 6. The rolling cart of claim 1, further including a pair of wheels disposed, one each, onto an end of each of the first extendable leg and the second extendable leg adjacent to the bag support. 7. The rolling cart of claim 1, further including a latch pivotally connected to the first plate, wherein the latch has a generally U-shaped cross section and is arranged to engage the second plate such that the first plate and the second plate are aligned when the latch is engaged. 8. The rolling cart of claim 1, wherein the first extendable leg includes: a bottom tube forming a bottom bore extending at least partially therethrough;a middle tube forming a middle bore extending at least partially therethrough;a top tube; anda locking mechanism;wherein the middle tube is disposed at least partially within the bottom bore, and the top tube is disposed at least partially within the middle bore, such that the top tube and the middle tube extend telescopingly from the bottom tube when the first extendable leg is extended; andwherein the locking mechanism is arranged to selectively prevent a telescoping motion of the top tube relative to the middle tube and of the middle tube relative to the bottom tube. 9. A folding cart, comprising: a frame, including:a first extendable leg;a second extendable leg;a bag support connecting the first extendable leg with the second extendable leg;an inverted t-shaped hook suspended from the first and second extendable legs;a first plate defined on the bag support adjacent the first extendable leg; anda second plate defined on the bag support adjacent the second extendable leg;a vertical hinge rotatably connecting the first plate with the second plate such that the first plate is arranged to rotate relative to the second plate about a bag support axis of rotation;a handle connected between the first extendable leg and the second extendable leg, the handle including:a first half defined on the handle;a second half defined on the handle; andan additional hinge rotatably connecting the first half with the second half about a handle axis of rotation;wherein the rolling cart is arranged to fold when the first extendable leg and the first plate are rotated about the vertical hinge relative to the second extendable leg and the second plate, and to unfold in like manner, wherein when open, the first and second plates lie in a common plane with one another and with the first and second extendable legs, such that the open cart is flat, and is adapted to carry a backpack in this flat configuration, with the backpack suspended from the inverted t-shaped hook such that the inverted t-shape hook and the flat bag support provide the sole support for the bag. 10. The folding cart of claim 9, further including at least one auxiliary leg pivotally connected to the first plate, the at least one auxiliary leg being arranged to pivot away from the bag support such that the folding cart is capable of standing upright at an angle relative to a flat surface. 11. The folding cart of claim 10, further including: a hollow opening formed along a length of the at least one auxiliary leg; anda telescoping extension lockingly disposed within the hollow opening. 12. The folding cart of claim 9, further including a pair of wheels disposed, one each, onto an end of each of the first extendable leg and the second extendable leg adjacent to the bag support. 13.
