Abstract
A water skier safety alarm which is characterized by a flag-deploying mechanism mounted on a boat and designed to receive and deploy a flag when a water skier towed by the boat releases his grip on the tow rope handle. In a first preferred embodiment, the flag-deploying mechanism includes a mechanical linkage which employs a solenoid to normally retain a flag in lowered configuration when a water skier is gripping the tow rope handle and to deploy the flag when the handle is dropped, responsive to operation of a pressure-sensitive switch in the handle. In a second preferred embodiment, the flag is mounted on the telescoping end of an antenna and is stored in the antenna deployment housing when the water skier is gripping the tow rope handle. The flag is telescopically extended from the antenna housing responsive to dropping of the handle and activation of a pressure-sensitive switch in the handle.
 
Claims
Having described my invention with the particularity set forth above, what is claimed is:

1. A water skier safety alarm for a boat equipped with a tow rope having a tow rope handle, comprising flag deployment means carried by the boat; a flag staff carried by said flag deployment means in telescoping relationship and a flag secured to the extending end of said flag staff; normally open switch means provided in the tow rope handle; and wiring provided in the tow rope, said wiring connecting said flag deployment means to said switch means for activating said flag deployment means and raising said flag staff and said flag from a retracted position to an extended position responsive to release of the tow rope handle by a skier and opening of said switch means.



Description
BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to safety devices for water skiers and more particularly, to a water skier safety flag and audible alarm which is designed to deploy a flag and sound an alarm when the water skier releases the tow rope handle while skiing. In a first preferred embodiment, the flag is pivotally attached to a deploying mechanism which incorporates a solenoid to maintain the flag in folded configuration while the skier is holding the tow rope handle and deploy the flag upwardly when the skier releases the tow rope handle, either by falling or at the end of a ride. In a second preferred embodiment, the flag is attached to the end of a telescoping antenna and is normally telescoped inside an antenna housing when the skier is gripping the tow rope handle. The flag is extended telescopically from the antenna housing when the tow rope handle is released by the skier. In both embodiments of the invention an audible alarm may be utilized as desired, and the handle is equipped with a pressure-sensitive switch to operate the flag deploying mechanisms.
