Abstract: The subject of this disclosure relates to a diving apparatus and a method for marking a diver's' location. The disclosure provides a receptacle for diving equipment which is configured to float upon the surface of the water and optionally support a flag and pole to mark the diver's relative position underwater. An anchoring system is also disclosed coupling the apparatus to the sea floor or river bottom to maintain position of the apparatus in the general location of the diver. The apparatus further includes a perimeter ring handle, a receptacle for storing equipment, and a method for supporting a diver.
Abstract: Various embodiments relate to beverage accessory devices for use within beverage receptacles. In one exemplary embodiment, a beverage accessory device generally includes a housing having sidewalls defining a cavity therein. A substantially fluid-tight container is within the cavity of the housing. The container includes sidewalls defining a chamber. At least one of the container's sidewalls is spaced apart from at least one of the housing's sidewalls such that a portion of the housing's cavity remains separating the at least one container sidewall from the at least one housing sidewall. At least one electric light source is substantially entirely within the container's chamber. The chamber can also be configured for receiving at least one power source. The at least one electric light source is operable for illuminating at least a portion of a liquid within the beverage receptacle when the beverage accessory device is within the beverage receptacle.
Abstract: A device and method for training a young child how to swim. The child is restrained in an open rectangular shaped cradle which is pivotally mounted for rotation in a floatable body. Pointed screws engage spindles to lock the cradle to the floatable body with the child in an upright position. The inclination of the child is adjusted in increments from an upright position toward a horizontal position to permit the child to practice the arm and leg movements of a swimmer. The floatable body is comprised of a cellular plastic body and a reinforcement attached to an upper surface of the body. In an alternate embodiment, the floatable body is comprised of a thin planar center member and front and rear floatable members. Outriggers and keels increase the overturning resistance of the device. Extensible hand cranks increase the effectiveness of the training device.
Abstract: A carrying case for canoe that will hold supplies under watertight conditions, will not be dislodged from the canoe should it be overturned or subject to other violent exterior conditions, and will aid in flotation in subsequent righting, should the canoe be overturned. The case is configured to straddle the center thwart. It is waterproof and airtight. It has a plurality of securing latches which detachably grip the gunnels of the canoe. The cover extends four to five inches above the canoe lip to significantly increase the water displacement should the canoe be overturned, thus improving the flotation characteristics of the canoe and improving the user's ability to right the canoe with a small volume of water remaining within the hull.
Abstract: A submersible raft is disclosed for the cultivation of plant life such as seagrasses or the like. The submersible raft includes a first and a second longitudinal member of tubular configuration. The first and the second longitudinal members each have a first and a second end. A first transverse member extends between the first ends of the first and the second longitudinal members and a second transverse member extends between the second ends of the first and the second longitudinal members. The first and second longitudinal members and the first and second transverse members define a rectangular aperture therebetween. Tray supporting cradles extend between and are supported by the first and the second longitudinal members, the trays being supported below the rectangular aperture such that in use of the raft, pots of plant life to be cultivated are supported below the surface of the water in which the raft is submersed.
