ABSTRACT:
A walking spring device having two or more distinct walking springs. Each of the springs is initially located in parallel side-by-side relation, and has a first and a second longitudinal end. The second end of a first of the springs is rigidly connected to the first end of the adjacent spring. In use, the first end of the first spring is deflected to cause the spring to undergo the known "walking" motion to a lower level, such as an adjacent stair step. When the second end of the first spring is drawn to the next level, the rigid connection causes the first end of the second spring to also be drawn to the next level. This in turn causes the second spring to undergo the known "walking" motion. The second spring will then continue this motion to the next level yet, and then cause the first spring to follow. This alternating process is repeated through the length of the stairs.
