Abstract
A folding cart designed to function as a supporting walker or a stackable grocery cart. The frame consists of two pivoted parts, the shorter pivoted at its upper end to points near the center of the longer, and the longer extending thereabove to form a handle. A foldable strut joins the pivoted parts below their junction. A fabric receptacle is foldably supported from the frame generally above the junction of the two pivoted parts. Suitable wheels or pivoted castors are mounted adjacent the lower ends of the two pivoted parts.
Claims9
A foldable cart comprising a first unitary frame member having side members, a lower end member and an upper end member forming a transverse handle and having a first pair of wheel adjacent its lower end member;
- a second frame member having a lower end member and side members connected at their upper ends to a pair of first pivot points intermediate the upper and lower ends of the side members of said first frame member and having a second pair of wheels at the lower ends of its side members;
- a pair of collapsible struts joining each of said first and second frame members below said first pair of pivot points;
- a recpetacle comprising a rectangular fabric bag having sides and front and rear ends and suspended from said frame members by means of a pair of linear trnasverse rods joined to the upper edge of each end of said bag and supported by said frame members;
- both of said rods being connected to the side members of said first and second frame members by arms connected to the ends of said rods, said arms being connected to the side members of said frame members at second pivot points and the edge of each side of the receptacle being fastened to the side members of said first frame member above said second pivot points.
A foldable cart as claimed in clam 1 wherein the lower end member of said second frame member is fixed between said side members a substantial distance above said second pair of wheels.
A foldable cart comprising:
- a first unitary frame member having side members, a lower end member and an upper end member, forming a transverse handle and having a first pair of wheels adjacent its lower end member;
- a second frame member having a lower end member and side members connected at their upper ends to a pair of pivot points intermediate the upper and lower ends of the side members of said first frame member and having a second pair of wheels at the lower ends of its side members;
- a pair of collapsible struts joining each side member of said first and second frame members below said pivot points;
- a receptacle comprising a rectangular fabric bag having sides and front and rear ends and suspended from said frame members solely by means of a pair of linear transverse rods joined to the upper edge of each end of said bag and supported by said frame members;
- at least one of said rods being connected to the side members of one of said frame members by arms connected to each end of said one rod and pivotally connected to the side members of said one frame member;
- wherein said handle is substantially vertically above the axis of said second pair of wheels when in its normal operating position;
- and including a pair of detents on the side members of said first frame member on the upper surface of said side members each detect being positioned at a point on the side member a distance below the transverse handle of said first frame member to coincide with the position of the handle of a nested folded cart and having a rearwardly curved surface shaped to conform to the cross-section of the handle of said nested folded cart and so retain the folded cart in its nested position.
