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.

- 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;

- a platform coupled to the at least four wheels, wherein the platform comprises:
- lateral supports;
- 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 disposed between the first side and the second side and between the first set of wheels and the second set of wheels, and wherein the telescoping hitch is configured to extend 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 spring, 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the spring is disposed between an end of the pin and the first opening such that a force is applied to the pin to withdrawn the pin from at least one of the first opening and or second opening and when the force is released the spring causes the pin to extend further into the lumen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- wherein to position the telescoping hitch in one of the second positions, the pin is withdrawn from the second opening in the second member to allow the second member to extend away from the frame;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
- one or more modular top components removably coupled to the platform, wherein the one or more modular top components comprises at least one of a set of side walls, A-frame, or container.
