The collapsible and slidable cart provides for the transport of articles on both horizontal and oblique surfaces. The cart includes a pair of spacially parallel support members, each having a handle portion at the upper end and a wheel mounted for rotation at the lower end. At least one tray member for supporting articles extends outwardly from and is rotationally connected to the support members. Lock means which permit or prevent the rotational movement of the parallel support members relative to the tray member provides the cart user with means to collapse the cart for storage. The parallel support members have a curved, outwardly extending lower end portion so that the wheels extend outwardly from the remaining upper length. The curved lower ends having a low friction contact surface permits the cart to be transported on oblique surfaces, such as stairs. Also provided is a light-weight tubular cart construction which permits tray/support member rotation, as well as a hinged, tray perimeter member which permits the cart to be collapsed into a second configuration. Additionally, handle portion, curved lower portion, tray member, brace member, pouch member, elastic member, brake member, and hinged leg elements or configurations are provided to further enhance the use and function of the collapsible and slidable cart.

A collapsible cart for transporting articles having at least two wheels, at least one article supporting surface and being collapsible for storage, said cart comprising: a. two generally spacially parallel support members, each having a handle portion for gripping at its upper end and a wheel mounted for rotation at its lower end, said two parallel support members being of a light-weight, tubular construction and each having a tubular post member with an indented ring portion intermediate its length extending generally perpendicularly therefrom, b. at least one tray member for supporting articles, said tray member extending forward and outwardly from said spacially parallel support members and being attached for rotation to the post member extending from each said support member, said tray member further comprising an elongated tubular perimeter member having an indented circular wall structure at its opposite ends for receiving and for the mating rotational movement with the indented ring portions of said post members, and, c. means to lock said two parallel support members in a fixed and predetermined spacially parallel configuration by controlling the rotational movement of said perimeter member of said tray member relative to said support members, whereby, a user by operating said lock means can place said cart in either a configuration of use by fixing said tray member generally in a horizontal position or in a configuration for storage by rotationally collapsing the tray member of said cart.
