ABSTRACT:
Apparatus for simulating the sag, bounce and side-to-side sway of a tightrope consists of a beam formed by placing one fiberglass tube within another and a pair of spaced support members for supporting the beam at a desired distance above and generally parallel to a horizontal support surface. When a user steps on the beam, the outer tube deflects at a first rate, determined by its mechanical characteristics, until it encounters the smaller diameter inner tube whereupon its resistance to deflection is added to that of the larger tube. The position of the supports may be adjusted along the length of beam to allow the apparatus to be used by persons of different weights.
