Abstract
A wheeled, pushable cart for transporting cargo that when not in use can be stacked or nested in telescoping fashion, and which can be used with carts having a base frame to which the wheels are attached, and various components, which can include one or more baskets, that are attached to the base frame. The manner in which the wheels are attached and arranged, and the orientation of the base frame, provide for increased storage and ease of access to the base frame and bottom shelf from the rear of the cart, and easy nesting (also referred to as stacking) of multiple carts in telescoping fashion when the carts are not in use.
Claims12
A cart for transporting cargo, comprising:
- a) a bottom frame having at least a front portion, side portions, and a rear portion;
- b) a substantially flat-platform attached to said bottom frame to form a base frame structure and a substantially flat element on which cargo can be placed;
- c) a rear structure extending upwardly from said rear portion of said bottom frame, and side structures extending upwardly from at least a portion of at least one of said side portions of said bottom frame, operable to at last partially retain said cargo on said substantially flat element;
- d) at least 4 wheels attached to said base structure and extending downwardly for contact with the ground or other surface over which the cart travels when the cart is in use, said wheels each having a lateral inside edge and a lateral outside edge defined by the lateral width of said wheels and not their respective circumferences;
- e) two of said wheels being front wheels attached in proximity to the frontward portion of said base frame structure, wherein said two front wheels are in substantial lateral side-by-side alignment when viewed from the side, said front wheels having a lateral distance between their respective inside edges;
- f) two of said wheels being rear wheels attached in proximity to said rear portion of said base frame structure, wherein said two rear wheels are in substantial lateral side-by-side alignment when viewed from the side, said rear wheels having a lateral distance between their respective outside edges;
- g) the arrangement, placement, size and shape of said front wheels and said rear wheels being such that said lateral distance between said inside edges of said front wheels is greater than said lateral distance between said outside edges of said rear wheels;
- and
- h) said front portion of said base frame structure is higher relative to said rear portion of said base frame structure such that when the cart is in use the base frame structure is slanted downwardly relative to said surface a sufficient amount such that said bottom portion of said front portion is higher relative to said surface than is the top portion of said rear portion.
