Abstract
A safety alert for water skiers attachable to a tow boat and automatically actuated by a regulated release of tow line tension to elevate a flag to warn other boats that a skier is "down". An elastic member is operatively connected to a reciprocal flag standard and a tow line whereupon the memory of the elastic member elevates the flag into visible position when the tension on the tow line is released from the elastic member by the release of the skier therefrom. An intermediate member circumscribes a pull rope connected to the tow line and coacts with an obstructive member or knot disposed therein to regulate the actuation of the alert and prevent false messages from being transmitted thereby.
Claims9
A flag safety alert for water skiers comprising an open ended flag housing adapted to be mounted to the deck of a tow boat;
- an elongated flag standard having a flag attached to one end thereof and connector means attached to the other end thereof;
- a cylindraceous elastic member having elastic memory and operatively secured at one end thereof to said flag housing and having an extension member secured to the distal end thereof and extending axially therefrom;
- a pull rope extending axially in said housing and simultaneously secured to said connector means and said extension means at one end thereof and having a distal end attachable to a skier tow line whereby said pull rope when receiving tension from said tow line is operative to simultaneously elongate said elastic member and draw said flat standard axially into a non-visible position within said flag housing and when receiving no tension from said tow line ridges upwardly into said flag housing in response to said elastic memory of said elastic member which elevates said flag standard into a visible position, said pull rope having an obstruction defined thereon having a first diameter, said housing having a constricted throat defined therein adjacent the lower end thereof and having a second diameter smaller than said first diameter, said throat being adapted to pass said obstruction therethrough only in response to a preselected pressure applied to said pull rope from the other side of said throat thereby providing a regulator means.
