Foot-Operated Cart Brake Lever for Wheel Locking on Inclines

The braking system is segmented into independent lever arms for each rear wheel, with each lever arm containing a brake feature that independently engages with stops on its corresponding wheel. This segmentation allows the complex braking function to be distributed across multiple simple, identical components rather than requiring a single complex braking mechanism.

The brake lever arms are designed to be self-latching through the interaction between the brake feature and the radially disposed stops. Once engaged, the system maintains its braked state without requiring continuous user input or complex locking mechanisms, as the mechanical geometry of the lever arm and stops creates a self-sustaining engaged position.

The brake lever arm acts as an intermediary mechanical element that translates the simple downward motion of the user's foot into the rotational engagement of the brake feature with the stops on the wheel. This intermediary lever arm provides mechanical advantage and transforms the user's input into effective braking action without requiring complex linkages or mechanisms.

Instead of using a complex mechanism to release the brake, the system is designed so that the natural downward motion of the foot on the lever arm automatically engages and maintains the braked state. The engagement is the default state achieved by simple downward pressure, while release requires a deliberate upward lifting motion, inverting the typical brake operation logic.
