  • Patent number: 9022825
    Abstract: 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 inflatable tube is fluidly connected to the container and is configured to inflate with the expanding gas when the chemicals are exposed to a liquid. 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.

  • Patent number: 7421970
    Abstract: Equipment for entering and exiting boats is addressed. Generally, the equipment is in the form of “divers' doors” for inflatable or similar boats. However, unlike existing inflatable doors, the doors discussed herein need not necessarily inflate. Instead, they may be formed as flaps moveable between closed and open positions. Ramped rub strakes or other aspects of the boats may assist in diverting water away from any gaps present when the flaps are closed but the boats are travelling at significant speeds.

    Abstract: The boat is delimited around its perimeter by a float closed upon itself and comprising at least two superposed floating fender sections. The lower fender section is longer than the upper fender section and extends locally beyond the upper fender section towards the outside. The projecting region delimited by the lower fender section beyond the upper fender section is covered by a covering fixed to the projecting portion of the lower fender section and to that part of the upper fender section bordering this projecting region. Thus, the boat is provided with a projecting zone forming a low platform area onto which a person in the water can raise himself or herself in order to get into the boat more easily.

  • Patent number: 5421757
    Abstract: A rescue raft that includes a buoyant, elongated floor and a pair of parallel air chambers or pontoons on each side thereof is disclosed. Together, the floor and the parallel flotation members possess sufficient buoyancy to prevent the raft and a victim thereon from sinking. The raft also includes series of graspable members, extending across the floor and distributed sequentially along its longitudinal extent, that facilitate a victim's entry onto the raft and, when oriented vertically, form a ladder that assists entry onto a rescue boat. In a first embodiment, the graspable members are a series of cut-out windows through the raft floor. In a second embodiment, similar windows are formed by transverse inflatable rungs secured to the parallel air chambers. In a third embodiment, the windows are replaced with buoyant segments or cushions that project from the floor.

    Abstract: Disclosed is a small power-driven water craft of the type whose body is composed in the main of longitudinal two parts, the deck and the hull, with a standing platform in the deck at its rear portion and a stearing handle in front of the platform. In the deck at its stern side end is provided a mounting board that extends far below the bottom of the hull, adapted to permit a displaced rider to climb on board from the stern, without suffering the usual difficulty in doing so because of the imbalanced state of a craft when it is just floating in the water. In a preferred embodiment, the mounting board is slidably disposed on a sloped surface formed at the stern for movement between a raised position where the board is pulled clear out of the water and a lowered position where it stands extending at an angle into the water, conveniently for a displaced rider to grip on to its surface with his toe or knee in getting on board.

    Abstract: An improved life raft with inflatable tubes having a boarding ramp attached to such raft wherein the raft is inflated by a hose interconnected by a coupling means and via a second hose to the raft such that the pressurized life raft chamber inflates the boarding ramp. The coupling means is a quick disconnect coupling means which in a connected condition is operative to main a flow connection between hoses and chambers but in a disconnected condition is operative to block the flow connection from both hoses and their respective chambers. A tension member is used to interconnect the quick disconnect coupling means to the raft and provides the means for disconnecting the coupling means when sufficient tension is provided as extending the distance between the coupling means and the raft. Such coupling means with the tension member can also be installed between the main inflating cylinder and the raft.

  • Patent number: RE32560
    Abstract: A stabilized life raft utilizing a fluid filled depending buoy chamber for overall stabilization and including as improved features thereon a peripheral skirt chamber which fills with the raft supporting fluid upon deployment of the raft and serves as a temporary stabilizer while the buoy chamber becomes filled. The buoy chamber includes baffles to impede the flow of the stabilizing fluid from one portion of the chamber to another in the event of a sudden weight shift within the raft. An improved valve permits a more rapid inward flow of fluid upon deployment of the raft and yet prevents outward flow in instances where the buoyant raft is suddenly thrust upwardly by elements such as waves. The raft, because of the particular placement of the various structural elements in conjunction with the placement of the survival gear and inflation system, is automatically self-righting.
