  • Life saving apparatus
    Patent number: 4047257
    Abstract: A lifesaving apparatus for use, for example, in rescuing a person who has fallen through the ice, includes a series of slats, flexibly connected to one another, forming a long flexible mat. One end of the mat is provided with an anchoring device, used to fix the end of the mat to the shore. The other end is provided with a flotation device, which may also serve as a core on which to roll the mat. The slats serve to spread the weight of the rescuer over the ice and the entire mat serves as a path to lead the endangered person to safety.
