Abstract
Provided herein is a wheeled cart useful for the transport of children and/or other cargo. The wheeled cart comprises a steerable member that permits user-controlled movement of the front wheel and hence steering while retaining contact of all three wheels with the walking or running surface. Inventive wheeled carts are suitable for use by the user while walking or running and simultaneous transport of a child and/or other cargo, provide a roll-cage for protection of the child and/or cargo in the event or a roll-over accident, and are advantageously adapted for folding and ease of transport when not in use.

A steerable wheeled cart, comprising:
- an upper frame assembly comprising a pivotable member;
- and
- a lower frame assembly pivotally connected to said upper frame assembly, said lower frame assembly comprising a guiding assembly,
- wherein said upper frame assembly is slideably attached to said lower frame assembly at said guiding assembly.
A steerable wheeled cart, comprising:
- an upper frame assembly comprising a pivotable member;
- and
- a lower frame assembly pivotally connected to said upper frame assembly, said lower frame assembly comprising a guiding assembly;
- and
- wherein said guiding assembly is fixedly attached to said lower frame, said guiding assembly having a guiding channel and a latch, whereby collapsing motion of said steerable wheeled cart may be achieved by creating a temporary opening of said guiding assembly by applying downward motion on an upper side of said latch, whereby said upper frame assembly may be lifted upwards and away from said guiding channel of said guiding assembly towards a front area of said wheeled cart.
