Abstract
In various implementations, a modular wheeled cart may provide users with flexibility in use and transport. The modular wheeled cart may include interchangeable top components that allow the cart to be utilized as a wagon, a flatbed, an A-frame cart, etc. The modular wheeled cart may include a hitch, which allows the cart to be coupled to a vehicle. The wheeled cart may be motorized and/or may include a removable battery for ease of use.
Claims20
A modular wheeled cart comprising:
- a frame, wherein the frame comprises:
- a first end;

- a length between the first end and the second end;
- a handle coupled to the frame, wherein the handle comprises:
- a shaft;
- and
- a grip;
- wherein a portion of the shaft of the handle is rotatable about a shaft hinge;
- at least four wheels coupled to the frame, wherein the at least four wheels comprises:
- a first set of wheels disposed proximate the first end of the frame;

- a platform coupled to the at least four wheels, wherein the platform comprises:
- lateral supports that include fastener openings;
- at least one longitudinal support coupling the lateral supports together;
- and
- open regions between lateral supports;
- one or more platform handles coupled to the at least one longitudinal support;
- and
- a telescoping hitch, coupled to at least two of the lateral supports, disposed between the first set of wheels and the second set of wheels, and transversely spanning the width of the frame from a first side to a second side, and wherein the telescoping hitch is configured to extend perpendicularly from the first side between a first position and at least one second position;
- and
- wherein the telescoping hitch comprises:
- a first member coupled to the platform, wherein the first member comprises:
- a lumen;
- and
- a first opening;
- a second member disposable at least partially in a lumen of the first member, wherein the second member comprises a second opening;
- and
- a locking member, wherein the locking member comprises:
- a pin, wherein the pin is disposed through the first opening of the first member of the telescoping hitch and into the lumen of the first member;
- and
- a spring disposed about at least a portion of the pin, and wherein the spring is disposed between an end of the pin and the first opening such that a force is applied to the pin to withdrawn the pin from at least one of the first opening and or second opening and when the force is released the spring causes the pin to extend further into the lumen of the first member;
- wherein to position the telescoping hitch in one of the second positions, the pin is withdrawn from the second opening in the second member to allow the second member to extend away from the frame;
- and wherein when the telescoping hitch is retracted to dispose the telescoping hitch in the first position, the pin is disposed in the first opening of the first member and the second opening of the second member of the telescoping hitch;
- and wherein the second member of the telescoping hitch is capable of coupling with a vehicle hitch;
- and
- two or more modular top components removably coupled to the platform via the fastener openings in the lateral supports, wherein the two or more modular top components comprises at least an A-frame and a second modular top component.
