b) an elbow accommodating member comprised of an elongated central region of adjustable length terminating in opposed anchoring extremities bounded by upper and lower surfaces, said lower surfaces having non-slip gripping properties, and said upper surfaces having cushioned elbow receiving means and an upraised U-shaped embracing lip,
