  • Patent number: 10926484
    Abstract: A system and method for forming a seam between at least first and possibly second pieces of material used to form an inflatable product utilizes at least a first and potentially a second seam forming members that are attached to an inside wall of a piece of product material that comprises the inflatable product proximate each end. The inflatable product is comprised of one or more pieces of product material and one or more seam forming members located at any location where a seam is necessary. A first portion of the seam forming member attaches to a first edge of a first piece of product material and a second portion of the seam forming member attaches proximate a second edge of the first piece of product material. The seal forming can be accomplished by radio frequency, ultrasonic, heat or other types of welding, and adhesive or chemical based bonding.

  • Patent number: 10739037
    Abstract: A soft, flexible, solar pool heater for floating on water generally comprises independently inflatable outer ring and central portion. When chamber and cavity are inflated, the cavity is with the top and bottom planes of the ring. The ring can be inflated with water for holding the heater in a pool in winds. Holes through the central portion permit egress of air from under the central portion when the heater is placed on water. Valves for chamber and cavity are located near one edge such that the heater may be deflated by rolling from an edge opposite the valves. Magnets on the ring condition water and attach to similar floating heaters to form rafts.

  • Patent number: 10005529
    Abstract: A visual locator target easy to be seen from the air during the day or night to quickly locate and rescue the user in an emergency or distressed situation. The circular single-layer of bright, neon material used for this target may preferably have a diameter of 25? and be a strong, lightweight material the edge will glow-in-the-dark and inflate for water use making it easy to be seen at night for a quicker rescue. It can be used on land by laying it on the ground and securing it by using the eight anchor hook connectors. It can also be used to float in the water with the inflatable, luminescent circumference, center and cross-sections of the target which includes an inflatable chamber therein. The manual back-up air valve system requires the user to blow their breath into the air valve.

  • Patent number: 9302749
    Abstract: A non-self-propelled, floatable structure for supporting people, animals, machinery or other loads is disclosed, having a floatable body designed to float on water, and a retention skirt that protrudes downwardly from a peripheral edge of the floatable body. The retention skirt is designed to extend underwater, delimiting an internal space between the retention skirt, the floatable body, and the water. The retention skirt is airtight, preventing air passing through the skirt and towards said internal space. Thus, when a downward force is applied on an edge of the floatable body causing the opposite edge to start rising from the water, skirt airtightness beneath the rising edge creates a vacuum effect that stops the edge from rising and prevents the floating structure from swaying excessively and eventually turning over or capsizing. The retention skirt also limits or prevents lateral and transverse motion across the water surface.

  • Patent number: 7837526
    Abstract: A floatable workstation including an inflatable tube including optional partitions disposed internally within an air receiving cavity of the tube to form one or more inflatable chambers, each chamber including a valve for inflating the chambers. A plurality of corner fasteners is disposed on the corners of the inflatable tube or on a deck assembly. The deck assembly includes a plurality of deckboards assembled together to form a floorboard. The deckboards are assembled via an interlocking assembly feature. The deckboards are secured via a series of straps and D-rings. At least one deckboard may include a receptacle for holding tools or a bucket. A tether arrangement is attached to the floatable workstation for securely positioning the floatable workstation alongside a vessel allowing one or more persons to stand on the workstation to perform maintenance on the outer surfaces of a vessel. The tether arrangement includes tethers, a means for fastening the tethers to the handles, and suction mechanisms.

  • Patent number: 7666046
    Abstract: A rescue water craft comprising an elongated closed-loop tubular structure and a floor is described. The tubular structure has a mid portion and two end portions. Both end portions rise upwardly and outwardly from the mid portion at an angle comprised between 70 and 85 degrees. The floor partially runs along the mid portion. The floor is attached to and encircled by the tubular structure. Each of the two end portions defines an opening between the tubular structure and the floor.

  • Publication number: 20090302155
    Abstract: Flotation systems including separately packed floats and life rafts are disclosed. Such systems, advantageously used for helicopters or other vessels, attach rafts to exterior covers of the floats. Thus, if not needed, or if maintenance or repair is required, the rafts may be removed from the float covers quickly and easily and without unpacking the floats themselves. Likewise, removal of the rafts permits maintenance to be performed on the floats without any need to unpack the rafts. Also identified are mechanisms for indirectly connecting both floats and rafts to vessels and for independently inflating both floats and rafts using a single actuator.

  • Publication number: 20090053946
    Abstract: A method and apparatus for the self-illumination of various objects designed for use in sports, entertainment, safety, and emergency related activities. The objects are caused to self-illuminate by chemiluminescence to facilitate usage of the objects during non-daylight hours or in areas that are otherwise surrounded by darkness. Chemiluminescence may be activated through a variety of injection, acceleration, or tactile manipulation that are utilized to cause emission of visible light from within one or more cavities of the objects, from exterior portions of the objects, or from various inserts of the objects. Subcutaneous layers are also provided that may be caused to emanate visible light through chemiluminescence.
