Abstract:
A walking device for simulating a walking step of an animal, said device comprising:a) a frame having a first rocker arm mount, a second rocker arm mount and a crank mount positioned in a spaced relationship so as to regulate the walking step;b) a leg having a foot at one leg end, a centrally disposed knee joint and a hip joint at an opposite leg end from said foot;c) a first rocker arm axially connected at one rocker arm end to the hip joint and axially mounted to the first rocker arm mount at an opposite rocker arm end;d) a connecting arm having a knee coupling mount at a distal connecting arm end for operationally connecting the connecting arm to the knee joint, a crank rod connecting sit at a proximate end of the connecting arm and an elbow joint connecting site positioned between said knee coupling mount and said crank rod connecting site;e) a second rocker arm axially coupled to the elbow joint connection site at a first end of the second rocker arm and axially mounted to the second rocker arm mount at a second end; andf) a crank axially mounted to the crank mount for revolutionary motion about the crank mount at one crank end and connected to a crank rod at the crank rod connecting site of the connecting arm at an opposing crank end of the crank;with said first rocker arm and said second rocker arm upon the revolutionary motion of the crank cooperatively serving to limit the walking step of the leg to a reciprocating arcual motion as the knee joint is driven by said connecting arm.
