Abstract:
A walking stick with a flexure spring to store energy from compression during the user's step, and release of the energy to aid in propelling the user forward, thereby reducing fatigue and enabling longer and faster walks.
Walking Stick With S-Shaped Flexure Mechanism To Store And Release Energy
A walking stick that takes inspiration from nature to absorb energy in the downward first motion of a walking stride and then return the stored energy to aid in propelling the walker forward in the final forward motion of the walking stride all the while keeping the walker in an ergonomically correct position which minimizes discomfort and reduces wasted energy. The walking stick that is the subject of this patent application utilizes a dual flexure spring configured in an S-shape (hereafter referred to as an S-flexure spring) as an extension of the straight shaft of the stick. The shape and location of the S-flexure spring are such that the spring force helps propel the walker forward.
