The connection device has a connection structure made from a closed loop member, rotation arms, and connection members. A connection member is engaged with each rotation arm, and rotation of each rotation arm is restrained b the closed loop member, thereby fixing the buoyant body. To release the buoyant body, a trigger mechanism provided at the closed loop member is operated to fusion cut the closed loop member. Then, each rotation arm is rotated, and then the connection member comes out of each rotation arm, thereby releasing the buoyant body. | 10-23-2014 |

| 20140273678 | SELF-INFLATING DEVICE - A self-inflating device can include a container configured to receive a chemical compound, a one-way valve covering an opening leading to an inner volume of the container, and an inflatable portion fluidly connected to the inner volume of the container and configured to inflate with gas produced when the chemical compound is exposed to water. The inflatable portion can be configured to inflate when a gas pressure inside the self-inflating device exceeds a water pressure outside the self-inflating device. As the inflatable portion inflates with gas produced by the chemical reaction of the chemical compound, the inflatable portion can increase in volume and can displace water in a body of water. Consequently, the overall buoyancy of the self-inflating device can increase, causing the self-inflating device to rise in the water column toward the surface of the body of water where a user can easily retrieve the self-inflating device, as well as any object that is attached to the self-inflating device. | 09-18-2014 |
| 20150126084 | SELF-INFLATING DEVICE - A pressure-activated flotation device for use with an electronic device includes an attachment feature, chemicals, a container, a removable cap, an inflatable tube, and a pressure-activated valve.

The pressure-activated valve leads from the outer surface of the container to the inner volume of the container and includes a one-way valve that opens to allow liquid to flow to the inner volume of the container when the pressure-activated flotation device is submerged in the liquid to a depth where the pressure applied against the pressure-activated valve by the liquid is greater than an actuation pressure. The one-way valve also closes when the expanding gas generates a gas pressure inside the inflatable tube that exceeds a threshold. | 05-07-2015 |
| 20080311805 | Inflatable buoyancy device with water-dependant triggering mechanism. - This invention is directed toward a device which provides buoyancy to objects with negative buoyancy in water. The invention comprises a water-sensitive trigger which, when activated, causes a balloon to inflate, causing the object to float upon the surface where the user can then easily and safely retrieve it, through one of two mechanisms: first, a compressed gas is allowed to exit a canister and enter a balloon, second, one or more substances which, when mixed with water will produce bubbles are exposed to water and the balloon is filled with bubbles from the chemical reaction. There are a number of variable characteristics, including canister size and shape, trigger fuse length, balloon configuration, and housing material that allow a user tremendous flexibility in selecting a proper size of the invention for the user's intended purpose. | 12-18-2008 |
