Patent ID: 7445138

Claim:
A passive exoskeleton for aiding a user in bearing a load, the passive exoskeleton comprising: a rocker for attaching with a body member, the rocker having a travel channel and a load channel incorporated therein, the travel channel being an elongated channel oriented directionally from proximate the body member to a ground surface, and the load channel formed as an elongated channel and positioned such that an angle between the load channel and the travel channel is less than ninety degrees, both the load channel and the travel channel formed to accommodate a load pin, the rocker also including a top component; a bias block for attaching with the body member and for engaging with the top component of the rocker, both the bias block and the top component of the rocker are formed in such a manner that as a user walks and shifts between a swing phase and a stance phase, the top component of the rocker passes a point of equilibrium where the bias block turns the rocker to aid the load pin in transferring between the load channel and travel channel, thereby shifting the load from the rocker onto the load pin and ultimately to a ground surface, causing the passive exoskeleton to support at least a portion of the load.
