Definitions

  • the present invention relates to a lifting device for a run on the ground vessel comprising at least one attachable to the ship's hull buoyancy, which is inflated by air if necessary, to lift the hull, wherein a force acting on the buoyant traction means is provided by means of which the buoyancy of about Deck can pull under the boat in the longitudinal direction.
  • the device comprises an airtight inflatable envelope held by a plurality of support members on the side wall of the hull.
  • the support elements consist of telescopic extensions, which are hinged by means of hinges on the hull wall of the hull.
  • a disadvantage of this known device on the one hand the fact that it must be attached to the outside of the hull. For this it is necessary to drill holes in the hull. Such holes are potential weak points where water can penetrate. Also, for the connection between the housed inside the boat compressor and the inflated casings of the buoyancy bodies holes in the side wall are necessary because the compressed air line is passed through the side wall to the outside. Another disadvantage arises from the fact that the device is permanently attached to the outside of the hull and thus an increased flow resistance arises, so that when driving under a machine significantly higher fuel consumption is produced, which is unacceptable.
  • lever lifts On the American market, there are essentially so-called lever lifts. These are fixed to a, often private, dock and serve to lift the boat or yacht out of the water. This serves mainly to maintain the value of the boat, as it does not cause algae growth. This significantly reduces the care required. Care products need hardly be used and protect the paint and the environment. Saltwater does not attack the boat or boat paint while the boat is jacked up. However, these boat lifts are only suitable for motor boats. These known devices are too heavy as they are i.d.R. made of metal or plastic. They do not swim and are almost always designed to be firmly fixed in harbors or jetties.
  • Floating versions of such devices are designed to be filled with water, the boat enters the device, the floats are dewatered with the aid of compressed air and the boat is then on the floats. Since these floats are made of plastic, they are so bulky due to the boat mass to be carried that they can also be considered as a “mobile” and “stowable” solution out of the question.
  • mountain bags from diving which are also used by salvage companies.
  • These sacks are usually handy and not heavy. They are used to recover lost or lost items. For example, With such backpacks an outboard motor can be lifted from the ground. These sacks are usually open at the bottom because the diver uses his oxygen cylinder to fill the bag with air from below, controlling the buoyancy.
  • a device for lifting a sports boat in which two buoyancy bodies are provided, which are each attached via ropes on the side of the hull.
  • the two buoyancy bodies are interconnected by a plurality of cables and have along a bar eyelets, can be pulled through the other ropes, by means of which the buoyancy bodies can be mounted both in the bow area and in the rear of the boat.
  • This known device is used to safely secure boats that are unused for a long time at an anchorage. The device is therefore not intended for damaged boats.
  • the buoyancy bodies are determined by means of the ropes in the intended position in the rear region of the hull and it is not intended to pull the buoyancy bodies from the deck under the hull.
  • the buoyancy bodies are seen in the transverse direction of the boat only connected below the hull.
  • a mobile self-lift assembly in which two inflatable tubular body via positioning lines are each mounted laterally below the boat hull.
  • the positioning lines are fastened at the top in several places on the deck of the boat and run approximately vertically from top to bottom, so that they form a kind of net around the hull around.
  • tensioning elements In the bow and stern areas below the waterline are respectively tensioning elements, which can be stretched over belt tensioners around the hull of the boat. After tightening, the tubes are inflated to lift the boat.
  • the DE 42 14 019 A1 describes a device for lifting boats from the water with the features of the type mentioned.
  • a single buoyant body is provided in the form of a shallow hull, which is laid out in front of the bow of the boat on the water surface and then pulled with the help of Glasgurten which are fixed to the shell near its outer sides, from the deck of the boat under the hull can be. Then this shell is filled with air to lift the boat.
  • This known device has the advantage over the solutions described above that it can be brought from the deck of the boat in the lifting position.
  • this device is only suitable for use in low-bottomed boats that have no keel, which usually applies only to pleasure boats.
  • the device In common Botten with keel, the device is not applicable, because the keel moving the plate-shaped Buoyancy under the boat prevented.
  • the disadvantage in this device that the boats after lifting by means of the buoyant body is no longer manoeuvrable. The boat can not drive more, but must be towed, which requires a higher effort. In the event of an accident, the owner of the damaged boat would in any case depend on outside help.
  • the object of the invention is to provide a structurally simple lifting device of the type mentioned, which is also suitable for run on boats or ships with keel, whose deck is still above the water surface, which are carried in the boat can and is used when needed, which is easy to handle, which can be operated in the event of an accident, if necessary, by only one person and after lifting still allows a maneuvering of the boat.
  • At least one buoyancy body is provided, the areas of which are effective during lifting and extend laterally along the hull on both sides and leave a free space in the area associated with the keel below the middle of the boat, the at least one pulling means acting on the buoyancy body (s) acts on both effective when lifting areas.
  • a first preferred variant of the invention provides that at least one buoyant body is present, which has approximately a U-shape in plan view, wherein its U-legs each form laterally along the hull extending areas which extend through a in the transverse direction of the boat extending U-web are connected to each other, which engages in the boat-mounted state of use under the bow of the boat.
  • This solution has the advantage that due to the U-plan shape of the central area under the boat, where the keel is located, remains free. Nevertheless, the two laterally along the hull extending areas through the U-web preferably in the direction of travel of the boat forward (ie in the bow area) connected to each other, whereby the inflatable area of the buoyancy body forms a unit.
  • the front Underbridge creates additional lift under the bow area of the boat and lifts it there as well.
  • At least one, preferably a plurality of guide means are provided for each along this U-leg extending traction means on both U-legs of the buoyancy body, wherein a tensile force is generated on the traction means, starting from a rear portion of the boat and wherein attack points of Traction and / or guide means are provided on the buoyant body at least in the rear region of the buoyant body on both U-legs.
  • a further alternative variant of the present invention provides that at least two buoyancy bodies are present, which are interconnected by at least one connecting means extending substantially in the transverse direction to the longitudinal extent of the boat, wherein a traction means acting on both buoyant bodies is provided, by means of which the Buoyancy body can pull over deck in the longitudinal direction of the boat. Also in this variant, there is the advantage that the area is free in the middle of the hull, so that the device can also be used for boats with keel. In both variants, there is also the advantage of maneuverability of the boat after lifting, so that it can move either by motor or by sailing.
  • At least one substantially extending in the transverse direction connecting means is at least partially formed as a rope, chain, or belt or rod or strut.
  • a preferred development of the second variant of the present invention provides that the connecting means forms a first connection between the buoyancy bodies, which extends in the application position in the lifting position of the device transversely below the boat hull and that this connecting means or another connecting means further comprises a second connection between the Buoyancy bodies that runs in the lifting position above the boat hull. This results in a quasi a leadership of the buoyancy around the boat hull, when the buoyancy bodies are pulled along the boat backwards.
  • At least one first flexible or largely rigid connecting means extending substantially in the transverse direction is provided, and in addition a further connecting means, which also extends essentially in the transverse direction, is provided.
  • the at least one pulling means acting on the buoyant bodies is at least partially formed as a pull rope.
  • this may be a pull rope, which acts simultaneously on both buoyant bodies with approximately the same force, so that a single person can comfortably pull both buoyancy bodies approximately parallel and in approximately the same position opposite one another along the length of the boat to the desired lifting position.
  • a traction means is provided for each buoyant body, which is attached to this, so that each buoyant body can be pulled for each along the boat to the rear in the lifting position.
  • buoyancy bodies in the final position are preferably as close as possible to the hull and below the waterline, then the buoyancy bodies are inflated by means of compressed air, which reach under the hull and the boat is lifted to the extent that it detaches itself from the bottom of the body of water, again maneuverable and, for example, by means of the marine engine from the shallows on which it had accumulated, can be maneuvered away into free waters. It may be obvious that this maneuver may also be practiced by a single person during a period as short as possible to minimize the damage caused by movement of the boat due to running.
  • the buoyancy bodies used in accordance with the invention advantageously have an elongated basic shape or else a round, crowned or bulbous basic shape and extend essentially longitudinally along the hull, as close as possible to the hull or completely adjacent thereto.
  • At least one flexibly designed connecting means and / or traction means an aid for increasing the tensile force, in particular in the form of a talje.
  • the device of the invention can also serve as Kentertik fall dry, in which case the lifting device serves as a Bergebaum and is located between the bottom and side wall of the boat.
  • the lifting device can also be used for example for Havaristen on the beach. It can also serve as a buoyancy aid in the event of a leak.
  • the idea of the invention is based on the idea that under different sailing and weather conditions, in tidal waters, in the charter segment or in the recreational area of sailing, it comes again and again to ground touches with ships and boats.
  • the lifting device according to the invention can also be used for light repairs on the underwater vessel.
  • the device is fixed in the appropriate place and you can the boat, for example. in the foreship area to lift the required centimeters out of the water by e.g. clean the log or perform other checks or repairs.
  • An essential aspect of the invention is based precisely on the fact that the lifting device is mobile and in a practical bag on board, for example. can be carried in the back box. So it's a mobile, fast-to-deploy, on-board solution.
  • the buoyancy bodies for example, the buoyancy bodies, the connecting compressed air hoses and the compressor are included.
  • the connecting ramps (ropes) and mounting accessories can be found here.
  • the object of the invention is to provide a rescue and rescue system, in particular for sailing yachts, which can raise yachts which have run aground in such a way that the yacht remains manageable and, above all, by a single person such as a yacht. the owner, skipper or any other person can be deployed on board and fixed on the ship. In this case, it is usually sufficient if, for example, alongside buoyancy bodies lift the boat by several centimeters.
  • buoyancy bodies are deployed in the uninflated or unfilled state over the bow of the ship and fixed to the ship so that they are attached below the waterline at the level of the keel.
  • the lift generated which is preferably between about 5 and 20 cm, can be calculated individually for each boat type. It is therefore recommended that appropriate variants of the device are made available on the market for the different boat types and boat sizes. For example, classifications based on length and / or weight and / or displacement are suitable.
  • the idea of the invention is to attach the buoyant body (s) to the repair site. For example, only the fore or aft vessel could be raised. Especially with leaks can be prevented worse.
  • the buoyant body (s) are provided with heavy-duty straps adapted to the weight of the yacht.
