14. The cart of claim 13, wherein the frame handle has a curved frame portion that is retractable within the second frame portion, so that extension of the frame handle advances the frame handle towards the user standing behind the cart.
15. The cart of claim 13, wherein the first frame portion is curved so as to be convex towards a user standing behind the cart, whereby the first and second frame portions are convex in the same direction when the second portion is pivoted to a storage position.
16. The cart of claim 13, wherein the base has a brake at an end opposite the wheels, the brake shaped to provide a hand grip for carrying the cart when the first and second frame portions and the rack are pivoted to a storage position adjacent the base.
17. The cart of claim 13, further comprising a bag positioned above the rack, the bag attached to the rack and attached to one of the second frame portion and the handle.
18. The cart of claim 13, further comprising a bag attached to the first frame portion.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
