ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to flotation devices for watercraft and, more particularly, it relates to an automatically inflating flotation device that would improve the stability of the watercraft and inhibit the watercraft from sinking if the hull was breached. The flotation device is inflatable, either manually or automatically, when a predetermined amount of water entered the hull of the watercraft thereby increasing stability and inhibits sinking.
2. Description of the Prior Art
Boating is both a popular pastime and a vital commercial activity in much of the world today. A boat is often a substantial investment for the owner and/or operator. In the case of commercial boats, the boat is often the livelihood of the owner of the boat. As a general concept, boats sink when the hull of the boat takes on water and the boat loses its buoyancy. This can happen if the hull is breached due to a collision with some object or in heavy waves if the boat is swamped. If the boat sinks, a serious condition exists in that loss of life and loss of property often occurs.
A number of patents have been directed to inventions to prevent a boat from sinking, even if the hull was breached. Unfortunately, the previous devices for boat floatation have a number of problems such as being difficult to install and often require manual activation of the device. This is a major concern since many boats often sink unattended at the dock, not out on the open water.
The flotation device of the present invention solves these problems and others by being easy to install, either as a retrofit to an existing boat or during manufacture of the boat. In addition, the flotation device of the present invention is designed to automatically deploy when a predetermined level of water is consistently in the hull of the vessel. The device will not deploy when water merely splashes to that level, preventing unneeded deployment in heavy seas. Once deployed the present invention will keep the boat afloat even if a complete flooding of the hull has occurred.
The primary aspect of the present invention is to provide a deployable flotation device to keep the boat floating after water has partially filled the hull of the boat.
Another aspect of the present invention is to provide a flotation device that does not interfere with the looks or operation of the boat when not deployed.
Another aspect of the present invention is to provide for a flotation device that can be easily removed and a new one re-installed after deployment.
Another aspect of the present invention is to provide a device that is easy to manufacture and install.
SUMMARY
In particular, the present invention is a flotation device for maintaining a watercraft in a floating condition. The flotation device comprises a cover releasably secured to the watercraft. At least one directing bladder is positioned between the cover and the watercraft. At least one inflatable flotation bladder is positioned between the cover and the watercraft wherein upon inflation of the directing bladder, the directing bladder releases at least a portion of the cover from the watercraft.
The present invention further includes a method for maintaining a watercraft in a floating condition. The method comprises releasably securing a cover to the watercraft, positioning at least one directing bladder between the cover and the watercraft, positioning at least one inflatable flotation bladder between the cover and the watercraft, inflating the directing bladder, and inflating the flotation bladder.
Other aspects of this invention will appear from the following description and appended claims, reference being made to the accompanying drawings forming a part of this specification wherein like reference characters designate corresponding parts in the several views.
