Abstract
Mechanical and hydraulic implementations of the car jack are the only product of their kind that utilize a ratchet mechanism that lifts the vehicle with a simple step on the lever, minimizing effort and time needed for a tire change. This unprecedented product is uniquely designed with a robust tripod structure that guarantees stability and support as the three legs provide a firm and secure base, eliminating the probability of wobbling or tilting during utilization. Moreover, the Step Jack weighs significantly less than traditional jacks, making it effortless to carry, while its folding ability allows for easy storage in a vehicle's trunk or glove compartment.
