  • Mobile cart with retractable wheel assembly
    Patent number: 9469321
    Abstract: A mobile cart having a retractable wheel assembly. A control rod engages the gear mechanisms coupled to the deployment rods. As the control rod engages the gear mechanisms, the gear mechanisms rotate the deployment rods between a deployed state and a retracted state. The ends of the deployment rods that are located within each wheel base push against the top portion of each wheel housing, thereby pushing each wheel housing out and away from the wheel bases so that the mobile cart may be pushed on the exposed wheels.
