摘要:
A floatation device of any size or shape stabilized by a ballast system comprised of sponge contained in permeable enclosures, which enclosures in turn are secured to the underside of the device, which sponge, upon contact with water, rapidly absorbs such water and provides prompt, sufficient ballast.

Disclosed is an inflatable boat having a self-inflation system which advantageously makes it possible to shorten the air injection time, thus quickly taking a proper measure under an emergency situation, in such a manner that a speed tube or an air passage tube disposed in the boat's body and an air distribution system each help inject compressed air into a plurality of compartments forming the boat's body simultaneously at a designated pressure.

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.

A device for rescuing, retrieving and setting free native wildlife caught in a swimming pool skimmer comprises a body and a retrieval apparatus. The body has a base and an elevated surface of lesser external dimensions than a flange of the base. The body has an enclosed volume captured between the base and the elevated surface. The retrieval apparatus is associated with a portion of the body.
摘要:
This invention relates to a naval rescue vessel, comprising a propulsion unit (1) powered by a water jet and a hull unit (200), wherein said hull unit is at least partly flexible and wherein said propulsion unit (100) is arranged to form a rigid unit, and wherein the two units (100, 200) are interconnected to form a naval rescue vessel intended to be handled/manoeuvred by a single rescuer, wherein the interconnection (130, 205) between the two units (100, 200) is arranged to provide a releasable connection of the units.
摘要:
A rescue apparatus comprises a plurality of elongate, buoyant, rigid members attached at their respective ends to one another at a selected one of a plurality of possible angles relative to one another and in a manner to prevent relative movement between the attached members. Any number of the members can be affixed together to form one linear section, to form a length with a zig-zag configuration, to form an L-shaped length of members to extend around a corner, to form a hook or loop shape at the end of a straight length, or virtually any other configuration which might be advantageous in a particular water or ice rescue situation. At least a portion of the rescue device is extended to a position within reach of the victim to affect the rescue. In a preferred embodiment, three of the members have been attached together to form a triangular rescue device that can be thrown or launched near the victim for use as a floatation device.
摘要:
The present invention relates to an inflatable liferaft comprising at least an inflatable first tube, an inflatable second flotation tube, said first and second flotation tubes being adapted to be arranged substantially above each other, said first and second flotation tubes extending circumferentially for providing a substantially ring-shaped area; and a bottom element which is adapted to provide a bottom to the substantially ring-shaped area. Furthermore, said first and second flotation tubes are arranged separately substantially above each other, and said first and second flotation tubes are mainly connected via said bottom element.
摘要:
A floating apparatus is arranged to be propelled manually. The apparatus has a float with a head and a foot for supporting a recumbent person. Also included is a hull attached under the float. The hull has a first end and a second end and is narrower than the float. The apparatus has a propeller shaft with a propeller that is rotatably mounted in the hull. Also included is a manual driver for rotating the propeller shaft. The manual driver is mounted at the first end of the hull and the propeller is mounted at the second end of the hull.
摘要:
The present invention relates to a floatable unit for evacuation purposes, which in a storage situation comprises at least two shells made of rigid or semi-rigid material, said shells being adapted to accommodate a deflated structure. Said deflated structure of the unit, during an evacuation situation, is inflated and the shells are attached to the inflated structure whereby the shells operate as hull parts for the floatable unit.
摘要:
A sea survival device (1) comprising a container (2) with several shells (3, 4) enclosing respective pneumatic liferafts (5, 6) in the deflated and folded-up state, and inflation means; one half-shell (4) enclosing a liferaft (6) is closed by a closure partition (7); the automatically triggered inflation means are operationally associated with at least the first liferaft (5) in a manner such that said first liferaft (5) is inflated first when the survival device (1) is deployed operationally; and the liferaft (6) is operationally associated with inflation trigger means suitable for trigging inflation thereof only once the first liferaft (5) is inflated.
