A braking system for a cart is described herein. The braking system can include a pair of chocks positioned proximate to a wheel of a wheel assembly, where the wheel assembly is coupled to a cart frame. The braking system can also include a handle mechanically coupled to the cart frame, where the handle has an engaged position when a force is applied to the handle, and where the handle has a disengaged position when no force is applied to the handle. The braking system can also include a brake release mechanism coupled to the pair of chocks and the handle. When the handle is in the disengaged position, the pair of chocks are engaged with the wheel and the brake release mechanism is disengaged. When the handle is in the engaged position, the pair of chocks are disengaged from the wheel and the brake release mechanism is engaged.

1. A braking system for a cart, the braking system comprising: a pair of chocks positioned proximate to a wheel of a wheel assembly, wherein the wheel assembly is coupled to a cart frame of the cart;a handle mechanically coupled to the cart frame, wherein the handle has an engaged position when a force is applied to the handle, wherein the handle has a disengaged position when no force is applied to the handle, and wherein the force applied to the handle is also used to move the cart; anda brake release mechanism coupled to the pair of chocks and the handle, wherein the brake release mechanism comprises: a bracket assembly coupled to the pair of chocks, wherein the bracket assembly comprises: a slotted portion;a first pair of crossing rods positioned adjacent to an outside-facing side of the wheel, wherein each of the first pair of crossing rods comprises a first end and a second end, wherein the first end of each of the first pair of crossing rods is coupled to one of the pair of chocks, and wherein the second end of each of the first pair of crossing rods is slidably coupled to the slotted portion of the bracket assembly; anda first nexus positioned where the first pair of crossing rods intersect; anda linking device comprising: a first end of the linking device coupled to a distal end of the handle; anda second end of the linking device coupled to the slotted portion of the bracket assembly,wherein the wheel assembly comprises a wheel base and a fork that couples the wheel to the wheel base, wherein the wheel base is coupled to the cart frame and the first nexus,wherein, when the handle is in the disengaged position, the pair of chocks are engaged with the wheel and the brake release mechanism is disengaged, andwherein, when the handle is in the engaged position, the pair of chocks are disengaged from the wheel and the brake release mechanism is engaged. 2. The braking system of claim 1, wherein, when the pair of chocks are engaged with the wheel, each chock of the pair of chocks is wedged between a wheel surface and a ground surface. 3. The braking system of claim 1, wherein, when the pair of chocks are disengaged from the wheel, each chock of the pair of chocks avoids contact with a wheel surface and a ground surface. 4. The braking system of claim 1, wherein the wheel is positioned toward an end of the cart where the handle is positioned. 5. The braking system of claim 4, further comprising: an additional pair of chocks positioned proximate to an additional wheel of the cart, wherein the additional wheel is positioned toward the end of the cart where the handle is positioned. 6. The braking system of claim 1, wherein the bracket assembly further comprises: a pulley rotationally coupled to the first nexus, wherein the linking device is flexible and wraps around at least a portion of the pulley. 7. The braking system of claim 1, wherein the bracket assembly further comprises: a spring bracket coupled to the cart frame and positioned above the slotted portion;a spring coupled to the slotted portion and the spring bracket. 8. The braking system of claim 1, wherein the bracket assembly further comprises: a second pair of crossing rods positioned adjacent to an inside-facing side of the wheel, wherein each of the second pair of crossing rods comprises a third end and a fourth end, wherein the third end is coupled to the one of the pair of chocks, and wherein the fourth end is coupled to the wheel base; anda second nexus positioned where the second pair of crossing rods intersect and coupled to the wheel base. 9. The braking system of claim 8, wherein the first end of each of the first pair of crossing rods and the third end of each of the second pair of crossing rods are coupled by a pin, wherein the pin traverses a chock of the pair of chocks. 10. The braking system of claim 1, wherein the slotted portion is V-shaped. 11. The braking system of claim 1, wherein each of the pair of chocks are wedge-shaped. 12. The braking system of claim 1, further comprising: a spring bracket coupled to the cart frame and positioned below the handle; anda spring coupled to the handle and the spring bracket. 13. The braking system of claim 1, further comprising: a locking feature configured to hold the handle in the engaged position. 14. The braking system of claim 1, wherein the handle is hingedly coupled to the cart frame using at least one fastening device. 15. A method for controlling a braking system for a cart, the method comprising: applying a first force to the handle, wherein applying the first force to the handle engages the handle and lifts a pair of chocks coupled to the handle and positioned proximate to a wheel of a wheel assembly of the cart;applying, while the handle is engaged, a second force to the handle of the cart to move the cart; andremoving the first force from the handle to disengage the handle and to engage the pair of chocks with the wheel of the cart,wherein applying the second force to the handle of the cart when the handle is disengaged fails to move the cart,wherein the handle is coupled to a brake release mechanism comprising: a bracket assembly coupled to the pair of chocks, wherein the bracket assembly comprises: a slotted portion;a first pair of crossing rods positioned adjacent to an outside-facing side of the wheel, wherein each of the first pair of crossing rods comprises a first end and a second end, wherein the first end is coupled to one of the pair of chocks, and wherein the second end is slidably coupled to the slotted portion of the bracket assembly; anda first nexus positioned where the first pair of crossing rods intersect; anda linking device comprising: a first end of the linking device coupled to a distal end of the handle; anda second end of the linking device coupled to the slotted portion of the bracket assembly,wherein the wheel assembly comprises a wheel base and a fork that couples the wheel to the wheel base, wherein the wheel base is coupled to the cart frame and the first nexus of the bracket assembly. 16. The method of claim 15, wherein the first force is greater than a third force applied to the handle, wherein the third force disengages the handle. 17. The method of claim 15, wherein disengaging the handle comprises: removing the second force from the handle, wherein each chock of the pair of chocks is wedged between a wheel surface of the wheel and a ground surface.
