Abstract
Abstract A flexible support rod is formed with a longitudinal channel for receiving a support rope. The channel extends from the upper end of the support rod downwardly along the longitudinal axis thereof and out the side of the rod. A locking cleat that releasibly secures one end of the rope is connected to the rod adjacent the egress. The support rod and rope may function as an amusement device providing the whip-like swinging action to a seat attached to the lower free end of the rope. Anyone can easily adjust the length of the rope by: (1) releasing the rope from the locking cleat; (2) extending the rope to the desired length; and then (3) re-engaging the rope in the cleat. When a hook is connected to the end of the rope, the support rod and rope may function, among other things, as a boat mooring device and the elasticity of the rod provides gentle pulling forces against any movement of the boat due to water surface currents and waves. Other embodiments may include a therapy device for bed-ridden patients.
