| 20080248703 | Buoyant mount for supporting articles in particular cinematographic apparatus upon or within a body of water. - A collapsible, height adjustable support device with inflatable buoyancy floats for mounting articles particularly cinematographic apparatus upon and below the water. It is characterised by a central tubular frame ( | 10-09-2008 |
| 20090075538 | SOLAR POWERED INERTIAL FLUID MOBILIZER - One embodiment of a fluid mobilizing vessel shown in FIG. | 03-19-2009 |
| 20130095713 | APPARATUS FOR RETAINING AN ITEM IN A BODY OF WATER - The present application discloses a retention device for retaining an item in a body of water, for example a swimming pool. In some embodiments, the retention device comprises at least one water-fillable receptacle connected to a retention element—for example a strap—that is placed over the item that is to be retained. When an upward force is applied to the retention element in a direction generally away from the surface of the body of water, the filled water receptacle restricts upward movement of the attached retention element, thereby maintaining the item in the body of water. | 04-18-2013 |
| 20160046357 | DEVICE FOR INCREASING BUOYANCY OF A SNORKEL OR A SNORKEL WITH ATTACHED MASK - The present invention is generally directed to a floatation device for a snorkel, including a body made from a buoyant material; and an orifice penetrating through the body, the orifice sized to receive a snorkel, such that the floatation device provides sufficient buoyancy to float a snorkel and an attached mask on the surface of water. More specifically, the body may be brightly colored and the orifice may be sized to cause an interference fit with an inserted snorkel. In accordance with some embodiments, the body may be wrapped or covered in a second material. | 02-18-2016 |

BUOYANCY UNDERWATER VIEWING DEVICE | 5 |
| 20100062665 | UNDERWATER VIEWING UNIT FOR AN AIR MATTRESS - An underwater viewing unit includes a tube insertable into a through-hole of an air mattress, a rest for the viewer's head provided at the lower end of the tube, and a transparent panedisposed within the tube. The head rest is formed by an inflatable beaded body connected to the upper rim of the tube and extending over less than 360° to leave free a peripheral region outside the tube for free breathing. | 03-11-2010 |

| 20130280974 | FLOTATION DEVICE HAVING A WINDOW AND A MASK TO PERMIT A USER TO VIEW BELOW THE WATER - A form-fitting comfortable mask, or sun screen, can be disposed, in tension, over a viewing compartment of a flotation device. The floatation device can provide the viewer with a safe, light and water resistant compartment that will greatly enhance their viewing of underwater details while minimizing or eliminating impact to their face from rough water conditions. The flotation device is designed to incorporate a tension surface with molded, water and light resistant air vents that support and secure a Neoprene and/or fabric sun screen mask with molded fasteners in a way that positions the sun screen/mask above the clear glass and/or plastic window. A hidden snorkel system between the viewing window and tension surface provides a fresh supply of clean air while restricting light and water from entering the viewing compartment. | 10-24-2013 |
| 20150321738 | BUOYANT VIEWING PLATFORM - A buoyant viewing platform for scanning the bottom of an aquatic environment from above so as to provide a clear, undisturbed field of view is provided. The buoyant viewing platform may include a body portion dimensioned and adapted to accommodate a human user on a top surface, wherein the body portion forms a viewing port for scanning bottom of the aquatic environment, and wherein a canopy may be disposed along the top surface so as to protect the user from the elements. | 11-12-2015 |
