Dependent claims

A collapsible cart configured to transition from a closed condition where it is folded up to an open condition where it is expanded for use, the collapsible cart comprising:

a frame defining a compartment, wherein:
the frame comprises at least five walls, with at least three of the walls configured to rotatably fold inwardly when the cart is folded up into the closed condition, two of which are opposing walls;
the two opposing walls each being rotatably coupled to a wall that does not fold inwardly when the cart is folded up into the closed condition;
one of the two opposing walls consists of a first panel and a second panel;
and
the second panel rotatably coupled to the first panel;
a first latch part disposed on an edge of the first panel when the collapsible cart is in the closed condition and the open condition;
and
a second latch part disposed on an edge of the second panel when the collapsible cart is in the closed condition and the open condition, wherein
the first latch part and the second latch part are configured to mate with one another and hold the first and second panels in a common plane when the first and second latch parts are latched together;
and
when the first and second latch parts are unlatched from one another, the second panel is capable of rotating relative to the first panel.

the third wall and the fourth wall each have a length from one edge to another;
and
the height of each of the first and second walls is less than half the length of each of the third and fourth walls, such that the first and second walls are substantially coplanar with each other when folded inwardly to the closed condition;
a coupler configured to selectively secure the first panel and the second panel in a substantially coplanar alignment, the coupler comprising:
a first coupler member disposed on an edge of the first panel when the collapsible cart is in the closed condition and the open condition;
and
a second coupler member disposed on an edge of the second panel when the collapsible cart is in the closed condition and the open condition;
wherein the first coupler member and the second coupler member are configured to mate with one another to hold the first panel and the second panel in the substantially coplanar alignment;
and
wherein, when the first coupler member and the second coupler member are disengaged, the second panel is able to rotate relative to the first panel.
