Abstract
A brightly colored underwater signaling device having a brightly colored watertight container filled with one or more freely-movable spherical objects. Vigorous displacement of the container causes the spheres to collide with and impact both each other and the inner wall of the container to produce an audible rattling sound with a pitch, timbre and intensity which is easily transmitted through water. The device is preferably constructed of PVC pipe containing a plurality of ball-bearings and connected to a skin diver's diving apparatus with a connecting strap.
Claims20
A hand held underwater signaling device for use by human skin divers comprising:
- an enclosed container;
- and
- one or more non-resilient objects contained within said container, wherein each said object is loosely-packed in said container such that vigorous manual displacement by the diver of said container will cause each said object to independently move and impact with an inner surface of said container causing audible sound vibrations to emanate therefrom.
A hand held underwater signaling device mountable to diving equipment for use by a human skin diver, comprising:
- a sealed, watertight container containing air;
- and
- one or more freely-moving non-resilient objects contained within said container which impact and collide with an inner surface of said container whenever said container is vigorously displaced manually by the diver, causing audible sound vibration to emanate therefrom.
A hand held underwater signaling device mountable to a skin diving apparatus for manual use by a human skin diver, comprising:
- a cylindrical section constructed of polyvinyl chloride;
- end caps constructed of polyvinyl chloride secured to either end of said cylindrical section with a sealant, said cylindrical section and said end caps forming a sealed, watertight container;
- and
- a plurality of freely moving solid spheres enclosed within said container which collide both with each other and with an inner surface of said container to produce audible sound energy whenever said container is forcefully displaced manually by the skin diver.
