Description

The present invention relates to a lifting device for a boat or ship that has run aground, comprising at least two buoyancy bodies which can each be attached laterally to the ship's hull, which can be inflated by means of air, if necessary, in order to lift the hull.

From the DE 203 03 464 U1 has become known an apparatus for lifting a run-on ship, in which along the hull of the ship buoyancy bodies are arranged, which can be brought from an inactive position in which they produce no additional buoyancy, in an active position in which they have an additional Generate buoyancy. 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. 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.

Otherwise there are so-called 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.

Due to their own weight, sacks of professional salvage can often not be handled. Moreover, their size and weight make them so unwieldy that they are almost impossible to move. In addition, they are hard to pay because of their very robust material.

Moreover, the prior art discloses various devices and floating cranes which are capable of over e.g. to drive a wreckage and to raise a sunken ship with the help of divers. This is not a mobile, flexible product solution for floating yachts. Floating cranes or devices are also out of the question for a mobile and one-to-handle solution, since they have already been developed for rather sunken ships because of their basic design. In addition, the use of such a device u.U. very long and is obsolete.

The object of the invention is to provide a structurally simple lifting device of the type mentioned is available, which is suitable for run on boats or ships whose deck is still above the water surface, which can be carried in the boat and at Need is used, which is easy to handle and in the event of an accident may also be operated by only one person.

The solution to this problem provides a lifting device according to the invention for a ship of the type mentioned above with the features of claim 1.

According to the invention it is provided that the at least two buoyancy bodies by at least a connecting means extending essentially in the transverse direction to the longitudinal extent of the boat are connected to one another and in that a traction means acting on both buoyant bodies is provided, by means of which the buoyancy bodies can be pulled from the deck in the longitudinal direction of the boat.

According to one embodiment of the invention, 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 embodiment of the present invention provides that the connecting means forms a first connection between the buoyancy bodies, which in the application position in the lifting position of the device extends transversely below the boat hull and that this connecting means or another connecting means further forms a second connection between the buoyancy bodies, which runs in the lifting position above the boat hull.

Preferably, according to a further development of the invention, 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.

Preferably, the at least one pulling means acting on the buoyant bodies is at least partially formed as a pull rope. For example, this may be a pull rope, which acts simultaneously on both buoyancy 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 each other along the length of the boat to the desired lifting position. Or in each case 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.

If the 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.

Should the force applied by hand be insufficient in an individual case to pull the buoyancy bodies along the boat far enough back, existing winches, for example, can be provided on the ship to exert a higher tensile force on the traction means. In this case, you can ever pull a buoyancy body by means of one usually at the rear of the boat on each side mounted winch, which has, for example, a crank to the rear and to the boat hull until the final position is reached. It is advantageous that these winches usually have a reverse lock, so that unintentional release of the pull rope is prevented.

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.

Due to their construction, sailboats and yachts are particularly affected.

It is not difficult to imagine the considerable damage and dangers to the life and limb of a ship's crew when such a boat runs aground in a stormy sea.

It is important to note that due to the prevailing waves, the boat hits the ground with every wave movement and thus permanently.

In today's modern fiberglass yachts, it does not take very long to significantly damage the outer hull or the ship's hull.

Optionally, the lifting device according to the invention can also be used for light repairs on the underwater vessel. For this purpose, the device is attached to the appropriate place and you can, for example, the boat in the foreship area lift the required centimeters out of the water to clean the log, for example, 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.

In this bag, for example, the buoyancy bodies, the connecting compressed air hoses and the compressor are included. Likewise, for example, 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.

The buoyancy bodies are discharged 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 focus of the site are probably essentially so-called tidal waters. But also unknown waters for charterers and Charterer come here in question.

In addition, the use for slight damage and / or repairs to the underwater vessel is conceivable. Straight impeller, log or solder are often vulnerable. All other ship breakthroughs could be supplied in an emergency.

The idea of the invention is to attach the buoyancy bodies to the repair site. For example, only the fore or aft vessel could be raised. Especially with leaks can be prevented worse.

The buoyancy bodies are provided for example with hard-wearing and adapted to the weight of the yacht straps. For example, via a cable system which is mounted crosswise and exerts tension on the buoyancy bodies, the buoyancy bodies can be pulled close to the keel below the waterline. For this purpose, the aft winches are preferably used to help.

Due to the various keel versions of sailing yachts, there is also the option to secure the buoyancy bodies securely with the help of light metal struts, which are fastened to the stanchion, for example in the height of the aft winches, so that they are clean and secure underneath the various types of ships Waterline and near the keel fin can be attached.

The buoyancy should be made of a durable material or sheathed. In the inner part is preferably a kind of rubber balloon with valve, through which the air can be pumped.

For example, the outer shell may have reflective stripes for safety and better visibility at night.

• 1.) Kompressor 12V
• 2.) Fußluftpumpe
• 3.) Druckluftkartusche

For compressed air filling of the buoyancy bodies, for example, the following components are considered:

• 1.) Compressor 12V
• 2.) foot pump
• 3.) compressed air cartridge

The compressor is small and handy and fills around 20l / min. A 12V connection is usually available on newer yachts.

For yachts that do not have electrical equipment on board, the option is available with a foot pump. Since these are usually smaller sailing yachts, the required air volumes are not that great either.

Alternatively, compressed air cartridges come into consideration, as they are known from lifejackets or liferafts, which, however, have the disadvantage that they are usually not regulated.

The features mentioned in the dependent claims relate to preferred developments of the task solution according to the invention. Further advantages of the invention will become apparent from the following detailed description.

Hereinafter, the present invention is based on embodiments below With reference to the accompanying drawings described in more detail.

Showing:

1 a schematically simplified plan view of an exemplary boat with a lifting device according to the invention, wherein the two buoyancy bodies are not yet inflated;

2 shows a further schematically simplified plan view of the boat in the state with the mounted and inflated two buoyancy bodies;

3 shows a schematically simplified side view of the boat in the state with the mounted and inflated two buoyancy bodies;

4 shows an enlarged detail view of a section 3 , Subsequently, first on 1 Referenced. This shows by way of example a schematically simplified plan view of a boat to which the present invention is applied, which is denoted overall by the reference numeral 10 is designated. In this view are already schematically two buoyancy bodies 11 . 12 , drawn, which have an elongated, for example in sections approximately cylindrical shape in the inflated state, which are shown here in the mounted position in which they each extend in the longitudinal direction on both sides laterally next to the boat and along the boat. The buoyancy bodies 11 . 12 are however in 1 are shown in a not yet inflated state and the ropes, by means of which the buoyancy bodies are pulled along the hull to the rear, are in 1 not curious, that is 1 shows a state in the attachment of the buoyancy bodies, but these are not yet in the final position.

Before inflation, the two buoyancy bodies 11 . 12 at the boat 10 attached by a connecting means 13 , which connects each of the two buoyancy bodies approximately near their front end area in the transverse direction of the boat, from the bow 19 to the stern 20 under the hull about up to the mast 21 was pulled. One sees therefore in 1 in that the connecting means 13 in front of the mast 21 running transversely under the hull. The connecting means 13 is thus below the waterline.

This pulling back the lanyard 13 and the two buoyancy bodies 11 . 12 along the boat in the longitudinal direction is done using a serving as a traction rope 14 or more ropes, which is a handling area located (in transverse direction) approximately in the middle of the boat 16 at which the operator can touch. From this handling area 16 from the rope extends to both sides to the outside and runs in the tensioned state (when pulling) forward and outward as indicated in the drawing to the respective attachment points 17 . 18 of the rope on the two buoyancy bodies, so that you can pull both buoyancy bodies towards the rear by a pulling movement, after the device in front of the bow 19 of the boat was thrown on the water. This traction device 14 Thus, in the embodiment also forms a further connection means between the two buoyancy bodies 11 . 12 which connects them below the boat hull, with the rope 14 also also above the boat between the two buoyancy bodies 11 . 12 runs in the transverse direction and this upper connection, at which one also attacks, in the drawing 14a ( 2 ).

The rope 14 runs on the one hand on the top of the hull and at the same time on the underside of the hull. For this it will be in the assembly of the buoyancy bodies 11 . 12 over the bow 19 pulled the vessel, so that this rope also serves as a guide for the movement of the buoyancy bodies 11 . 12 serves. This wraps around this other connecting means once the boat hull, preferably with some play. The attachment points of the rope 14 on the two buoyancy bodies, for example in the form of eyelets 17 . 18 be formed, which are located approximately in the front end portions of the buoyancy body.

When the buoyancy bodies 11 . 12 are mounted so that the connecting means 13 in front of the mast 21 located, the buoyancy bodies by means of a in 2 only schematically illustrated compressed air source, such as a compressor 26 be inflated so that the boat then floats by a distance and the boat hull thus dissolves from the ground. The compressor 26 is by means of compressed air lines 27 . 28 each with valves of the buoyancy bodies 11 . 12 and they are inflated until they have a plump, for example, approximately elongated cylindrical shape, where they invest in the boat hull as in 2 is shown while the ship 10 Lift. In 2 is the rear end position of the two buoyancy bodies 11 . 12 after assembly shown in the rope 14 is curious.

For additional determination of the buoyancy bodies 11 . 12 at the respective rear end on the boat is every buoyancy body 11 . 12 for example, a through an eyelet 23 Rope guided at its rear end 25 above deck, each on a fastener 24 of the boat. The two buoyancy bodies 11 . 12 But here are not directly connected with each other. This fastener 24 may for example be an existing winch on the boat, where you put the rope around this winch and exercise in this way a tensile force, pull the buoyant body to the rear and can tighten the rope. In the illustration according to 2 These are also the two rear ropes 25 streamlined and the buoyancy bodies 11 . 12 are in their rear mounted final position, where they can lift the ship.

Hereinafter, referring to FIGS 3 and 4 the present invention further explained. 3 shows a schematically simplified side view of the boat in the state with the mounted and inflated two buoyancy bodies 11 . 12 that is, according to the plan view of 2 , Here you can see the course of one of the now tensioned rear ropes 25 , the taut front rope 14 with the eyelet 15 and extending along the hull (in 1 and 2 ) right buoyancy body 12 , This buoyant body is now inflated and is located below the water surface 29 so that it attaches to the side of the boat and creates a buoyancy that lifts a boat sitting on the ground so that it becomes roadworthy again.

4 shows once again a schematically simplified detail of a section of a side view of the boat, in which case a variant with an additional attachment of the buoyancy body 12 is shown at its rear end. The buoyancy body is over a strut 31 on a stanchion on deck of the ship 30 fixed in its inflated lifting position.

When not inflated, the entire hoist does not take up much space and can therefore easily be stored on the boat on deck or below deck. The lifting device according to the invention is mobile, that is, it is not permanently mounted on the boat, but is only installed in case of an accident, to raise the boat slightly. Therefore, the lifting device does not interfere with the ride.
