Abstract
A cart may include a first set of lower support arms and a second set of lower support arms, each of the lower support arms having a wheel attached thereto; a first set of upper support arms and a second set of upper support arms; a holding frame coupled to the first set of upper support arms and the second set of upper support arms; a locking mechanism; and a folding mechanism configured to allow the cart to transition between a folded position and unfolded position. During transition, the first set of upper support arms may be moveable relative to the second set of upper support arms; the first set of lower support arms may be moveable relative to the second set of lower support arms; and the first set of upper support arms may be moveable relative to the first set of lower support arms.

A cart, comprising:
- a first set of lower support arms and a second set of lower support arms, each of the lower support arms having a wheel attached thereto;
- a first set of upper support arms and a second set of upper support arms;
- a holding frame coupled to the first set of upper support arms and the second set of upper support arms;
- a locking mechanism configured to releasably lock the cart in an unfolded position;
- and
- a folding mechanism configured to allow the cart to transition between a folded position and unfolded position, wherein during transition:
- the first set of upper support arms are moveable relative to the second set of upper support arms;
- the first set of lower support arms are moveable relative to the second set of lower support arms;
- and
- the first set of upper support arms are moveable relative to the first set of lower support arms;
- wherein the folding mechanism allows rotation of the first set of upper support arms, the second set of upper support arms, and the second set of lower support arms relative to the first set of lower support arms.
