Abstract
A water retrieval device that is attached to a valuable item to prevent that item from sinking and being lost in muddy or deep water. The device may be in the shape of a latex fish, which contains chemicals that react with the surrounding water that is drawn into the device. Once the device and the attached item are in the water, the device sinks and resurfaces to the top of the water with the reaction of the chemicals releasing carbon dioxide gas within the internal cavity of the device. The device then becomes more buoyant and brings the attached item to the surface of the water, thereby preventing the item from sinking further down into the water. The device can also be brightly covered and can protect a wide variety of items such as wallets, glasses and other valuables.
Claims6
A device for retrieving items submergible in water, said device comprising:
- a body made of an expandable material and having an outer surface configured to define a fish appearance, said body defining an internal cavity and a set of apertures;
- at least one band disposed within the cavity of said body, said band containing a chemical that generates a gas upon reaction with water;
- a thin outer layer resembling a fish gill and a thin inner layer, said inner and outer layers covering each of the apertures, said outer layer allowing water to enter the cavity of said body and said inner layer preventing escape of the gas generated within the cavity when the water reacts with said chemical;
- means for releasing pressure produced within the cavity of the body when the gas is generated;
- and
- means for attaching a retrievable item to said body.
