The whole equipment has its height setting through a linkage to an attachment point at the land. The flotation bodies are of aluminium, plastics, rubber elastic or thin steel materials. A number of identical profile units, of aluminium, iron or plastics, slide (19) vertically for height setting in relation to each other, with side intercoupling, but with independent floating or immersion and lifting actions.

Description

The invention relates to a device according to Preamble of claim 1,

Such a device is for example with the The subject of DE 42 14 019 become known.

In this known publication, the one to be raised Drive the hull onto a floating cushion, which The swimming pad is subsequently inflated to the Lift the hull out of the water.

With the subject of DE 44 26 194 is another Device for lifting boats in water has become known in which the well-known floating cushion principle is also included a magnetic holding device is combined, which Holding device with appropriate magnetic plates create a (metallic) hull and fasten it there should.

Another device is known from DE-GM 93 12 336 become also on the principle of floodable and ventilated float exists.

All embodiments have the task in common that one a hull floating in the water out of the water wants to lift out to the hull during its Raise rest time over the waterline.

This concept has great advantages in terms of that Winter storage after such boats that are familiar with the Devices are no longer used on dry land have to be brought out. They also have constructions Advantages because the underwater painting only during the  actual duration of use of the hull in water is claimed.

In the known devices, however, there is the disadvantage that the ship's hull is not safe enough to fall over hold; in particular, there is a lack of stability when inflating the hull, d. H. so while lifting the Hull out of the water.

In particular in the device according to DE 42 14 019 the center of gravity of the hull is exactly in the Middle of the inflatable pillow, which has the disadvantage is that with the hull raised to the side Tipping away tends.

DE 44 26 194 has the further disadvantage that the floats on the outside of the hull should invest, which leads to a sharp increase in required width of the entire device that leads consequently corresponding space in the water consumes what is not desired.

The invention is therefore based on the object To further develop the device of the type mentioned at the beginning that with much simpler and cheaper means a reliable lifting of the hull from the Water out and a storage of this hull over the Waterline (without risk of capsizing) is possible and that too the usable width of the entire device is essential is reduced.

To achieve the object, the invention is by characterized technical teaching of claim 1.

An essential feature of the invention is that now on the side a bearing block intended to accommodate the keel  at least two floats arranged in the longitudinal direction are which buoyancy elements are fixed with the bearing block or are slidably connected and that the entire device height-adjustable is attached to a connection point.

With the given technical teaching the essential becomes Advantage achieved that the previously mentioned bearing block now directly laterally with corresponding, in the longitudinal direction extending buoyancy bodies is connected. So that results the advantage that the bracket is practically only for Recording the keel part of the ship is determined and that the associated buoyancy body directly on this Keel area can connect, making the total itself resulting width of the device is significantly reduced.

This has the advantage that the entire device only essentially corresponds to the width of the ship because said buoyancy bodies below the ship the hull in the area of the keel line or next to it put on, and a side connection this Not buoyancy bodies on the side walls of the hull more is needed.

In a preferred development of the present invention it is envisaged that the connection between the keel-bearing pedestal and the associated buoyancy bodies that are held in their own frame, is adjustable in height. This results in the essential advantage that with this height adjustability now the lifting height of the hull out of the water can be adjusted. In this way it is possible to Bearing block for receiving keel boats (e.g. Training sailboats), but also (if appropriate reduced immersion depth) in the water can this bracket also for accommodating motor boats with a relatively flat keel be adjusted.  

In this way, the bearing block is for receiving provided by hulls, especially in the Recreational area can be used, namely motor boats, Sailing boats, rowing boats, pedal boats and the like.

Another essential feature of the invention is that now the inventive device for side coupling neighboring devices is formed. That is, According to the invention, several similar devices are used height adjustable (in the vertical direction to each other slidably) coupled to each other laterally, so that this Units swim independently in the water and are submersible and suitably liftable, but with the lateral coupling of the respective device to the neighboring device is associated with the advantage that the devices as a whole against lateral tipping are protected and the capsize security of such Device is significantly improved.

It is important that the side by side Devices are coupled together so that each Device can move vertically in the water separately, for which corresponding shift guides are provided, the e.g. B. can consist of appropriate roller guides, a corresponding device on one Roller arrangement is arranged, the z. B. in a vertical aligned career engages in the neighboring device.

Another embodiment of this height adjustment device consists in the fact that a device corresponding dovetail guide is provided, which Dovetail guide in a similarly trained Leadership of the neighboring device engages.  

Tongue and groove devices are also provided and the like more.

It is initially in the use position of the device provided that the floats are flooded and the entire device is so below the water line that the Bearing block for receiving the keel ship of a corresponding one Float is lowered so deep in the water. In this Diving positions only protrude from the water to the Fixings for the uprights arranged supports the water, preferably also with one in each Longitudinal handrail are provided. It deals is a type of boat garage that is submerged in the Condition only with her vertical out of the water outstanding supports and possibly parallel to Water surface arranged handrails is recognizable.

The hull to be lifted moves into the submerged Device into it, with the supports arranged on both sides ensure that the hull is well above the submerged Bearing block is centered, and at the same time the ship can can also be attached to the supports.

However, the invention is not based on the use of such Columns instructed. These supports can also be omitted.

It is assumed that the entire Device at a land-fixed point (connection point) is attached. Such a connection point can be a web be, a buoy, a floating dock, a pole or the like more. Otherwise, it is preferred if the entire Height-adjustable device at this web or connection point is attached to a constant assignment of the To reach device to the land-based connection point.  

This connection is preferably articulated or at least height-adjustable to ensure that the Connection to this connection point even with submerged Device is maintained.

Now when the hull is immersed in the device retracted, it is no longer necessary to To tie the hull to the side supports because appropriate centering between the supports already already enough. Otherwise it is not necessary for the solution that the supports on the hull invest.

As soon as the hull is centered on the device several pumps are put into operation are preferably designed as electric pumps and for them are suitable, those previously flooded with water Now float and empty the water from these Pump out buoyancy bodies. It is about this preferably around inexpensive, electrically operated Submersible pumps that are available in multiple versions.

The buoyancy bodies can be divided into several in a row lying chambers can be divided, with each chamber one corresponding submersible pump is assigned. That way namely also an individual flooding of segments of the Buoyancy body possible, so that also a certain Inclined position of the device submerged in water can be. In this way, the swimming position of the in Water immersed device can be set, just like also the swimming position of the later surfaced Device is set accordingly.

With the operation of the submersible pumps, the water from the Exhaust bodies removed, whereby - as previously stated - the Water more or less removed from the buoyancy bodies  is, so a precisely defined swimming position of the entire Ensure device in the water. The hull is now lifted out of the water so that the hull is out the water comes, whereby in the summer position the keel and the rudder still remain in the water while in the Winter position the height adjustment device on the pedestal so can be set that all in this position Underwater parts of the hull from the water be lifted out.

The hull is now in the winter position with its all parts in contact with water are lifted out of the water, which has the advantage that this device (as Boat garage) can remain in the water and the whole Hull receives a winter berth in the water.

This device has the advantage that in summer Underwater ship hull only with water is touched when the hull goes into operation during no longer during the rest of the underwater body comes into contact with the water. This will avoid that the environmentally harmful antifouling agents of Underwater ship no longer in contact with the water come and are only used if the Hull actually also for sports and recreational purposes is used.

Another advantage of the invention is that the Handrails only for additional fasteners Covers or tarpaulins can be attached, which creates a floating and submersible boat garage. So it is no longer necessary on the hull itself appropriate covers over tarpaulins or tarpaulins make because such a cover stationary on the Boat garage itself is attached.  

Such a device can also be used by a Operation must be equipped. In this case, between the Support a control cable stretched, which is the width of the Device spanned. If the hull is now in the Receiving space retracted this device, then bumps for example the bow together with this control cable, tightens this and this control cable is z. B. in Longitudinally guided rails arranged, which then the Longitudinal bow centered over the pedestal, and at the same time, with the tightening of this control cable Pump for emptying the float switched on be, which accordingly the entire Device is brought into its raised position.

The buoyancy bodies mentioned are safe against ice and exist preferably made of aluminum bodies, plastic bodies, rubber-elastic bodies or thin steel bodies.

The remaining parts of the device preferably consist of Aluminum profiles, from iron profiles or plastic profiles.

Devices of this type can therefore be used in multiples in the association Arrangement form a complete plant, which now in a much easier way to create a large number of hulls is guaranteed in a port facility.

Another advantage of the entire device is that that winter berths in the country can now be dispensed with and be created on water, with only relatively minor Drafts for these devices are sufficient to produce a corresponding raised position of the hull to guarantee. Even if the water level in the So winter is still the buoyancy of the device guaranteed.  

Another advantage of the device is that a substantial improvement in theft security for the Hull is given because the pumps and their electrical power supply can be permanently secured, and then it's no longer possible to get that out of the water to steal the raised hull.

In a further preferred development of the invention the boat height adjustment device consists of only two, the hull receiving and in the outer distance of the largest ship width, such as on one Bridge, tubes arranged parallel to each other that pass through assigned pumps are raised and can be lowered by flooding, so that the boat located on these tubes at empty pumped pipes above the waterline all year round can lie. With this boot lift the main advantage is achieved that the boat owner much lower costs than arise at a winter berth, also are not anti fouling more necessary and cleaning the bottom disruptive vegetation is eliminated.

Other advantages for the boat owner are that none Mast laying is more needed and transportation from the port to winter storage and back, and no crane fees accumulate and there is hardly any fear of osmosis.

Furthermore, the ship no longer has to prove when docking, and it can be put on the berth with one hand.

The boat stored in this way is a few easy steps Sea-ready and the underwater ship can be lifted without a crane to be controlled.

This preferred boat lift can also be used by a thief steel and burglar protection.  

This development of the present invention also has also significant advantages for the port operator who lies in the fact that the port can also be rented in winter can and the vacant areas for winter storage profitable, especially in the port area can.

The service work on the boats can be done on the whole Year be distributed evenly and thus peak times, such as especially in autumn and spring.

With this boat lift system, the boats can be placed closer together will; a dolphin is no longer necessary.

Finally, it is also possible to use these boot lift systems as well Use shifting systems so that at the same More boats can be accommodated.

The preferred boot lift system also has essentials Environmental benefits by eliminating toxic colors pollute the drinking water, no poison Grinding and washing the underwater ship on the These tubes are used for boats and also the buoys fields with this boat lift system to berth islands can be arranged.

The subject matter of the present invention provides not just from the subject of each Claims, but also from the combination of individual claims among themselves.

All in the documentation, including the summary, Disclosed information and features, in particular those in the Drawings illustrated spatial training are considered essential to the invention, insofar as they are used individually or in Combination are new compared to the prior art.

In the following the invention is based on only one Execution path illustrating drawings explained in more detail. Here go from the drawings and their description further features and advantages essential to the invention Invention.

Fig. 2 side view of the apparatus of Fig. 1 in the direction of the arrow II,

Fig. 3 top view in direction of arrow III in Fig. 2,

Fig. 4 side view of the device, in a comparison with FIGS. 1 to 3 modified embodiment without representation of the hull

Fig. 5 shows the top view of the arrangement of FIG. 4 in the direction of arrow V,

Fig. 6 a section along line VI-VI in Fig. 5,

Fig. 7 a section along line VII-VII in Fig. 5.

Referring to FIGS. 1 to 3 the apparatus essentially comprises a lower, submersible central pedestal 1, consisting of two mutually parallel longitudinal beams 3, which are joined at certain intervals by corresponding cross beams 4 to each other. Between the longitudinal bars 3 is a Kielauflager 5 is arranged, which is designed adjustable in the longitudinal direction between the longitudinal beams. 3

The hull 2 is now moved with its underwater ship and with its keel 33, if any, into the bearing block 1 , at the same time there are upwardly projecting, approximately vertically oriented supports 6 from the longitudinal beams 3 , on their free, upper ends support plates 7 for holding of the hull 2 are attached. Corresponding diagonal or transverse struts can also be present from the supports 6 , which extend to the cross members 4 according to FIG. 1.

Lateral gusset plates 8 are arranged on the outer sides of the supports 6 , which are connected to the supports 6 and are suitable for fastening corresponding buoyancy bodies 10 , 11 .

Each buoyancy body 10 , 11 extends approximately over the entire length of the device and is fastened to lateral supports 12 , 14 with further outer gusset plates 9 .

In the exemplary embodiment shown in FIG. 1 it is shown as an example that the buoyancy bodies 10 , 11 can consist of a hexagonal or polygonal profile.

In another embodiment, it is shown in Fig. 1 that the buoyancy body 10 , 11 'can also be round profiled. They can also have an oval, elliptical or any other shape. It is only important that they consist of preferably separate chambers, each chamber being assigned a corresponding pump 30 .

The upwardly projecting supports 12 , 14 adjoin the lateral gusset plates 9 , the inner, central supports 12 being connected directly to the bearing block 1 , while the outer supports 14 are connected to the buoyancy bodies 10 , 11 .

The connection between the bearing block 1 and the buoyancy bodies 10 , 11 is also made by two spaced-apart cross members 24 , 25 .

On the front crossmember 24 , the front supports 14 are fastened, on each of which a sliding bearing 18 is arranged, to which a drawbar 17 is fastened. This drawbar 17 is therefore arranged in a height-adjustable manner on the front support 14 and is fastened to an attachment point 34 .

In Fig. 1 is also shown that the neighboring device is coupled with a corresponding sliding bearing 19 with the device shown in solid lines in Fig. 1, which sliding bearing 19 ensures a mutual height adjustment of the coupled devices. The neighboring devices are only schematically indicated by the buoyancy bodies 10 , 10 'and the associated supports 14 '.

In Fig. 2 the raised position of the device in this case is shown, because the main part of the hull is above the waterline 13 (with the exception of the keel 33).

It can also be seen that the supports 12 , 14 are connected to one another by handrails 15 running in the longitudinal direction.

The rear part of the device which projects into the water is stabilized by a buoy 16 or by another floating body. In the exemplary embodiment shown, a chain 21 engages through the central recess 20 of the buoy 16 and runs through an associated bore 22 , which is located in a horizontal extension of the lower base point of the support 14 .

The chain 21 has a lower stop 23 .

If the entire device is now flooded by pumping water into the different chambers of the buoyancy bodies 10 , 11 via the pumps 30 , then the entire device sinks into the water together with the carrier 35 in which the bore 22 is arranged. The stop 23 then comes to rest against the support 35 because it does not slip through the bore 22 and the buoyant buoy 16 now carries the rear part of the device in the submerged state and in this way stabilizes the device.

It is important in the rest of FIG. 3 that the neighboring device is assigned the same buoy 16 , so that the device is assigned a left and a right buoy 16 , 16 'and each buoy 16 , 16 ' is also assigned to the adjacent device , which - as I said - is coupled via the sliding bearing 19 directly to the above-described device with adjustable height.

In addition, the entire usable width of the device can be adapted to the existing ship width in that the crossbeams 24 , 25 in the arrow directions 26 , 27 ( Fig. 6) are adjustable and have corresponding locking options.

In Fig. 6 it is also shown that the submersible pumps 30 have corresponding outlets 31 through which the water is pumped out of the corresponding buoyancy chambers of the buoyancy bodies 10 , 11 .

Appropriate ventilation devices are also available available, which ensure that when pumping out the  Air corresponding to water is sucked into the buoyancy body becomes.

Fenders 28 are preferably also arranged on the inside of the supports 12 , but they do not necessarily have to be attached to the hull itself.

Otherwise, appropriate diagonal struts 29 can still be attached between the corresponding longitudinal cross members 3 of the bearing block 1 and the associated cross members 24 , 25 , in order to achieve a stiffening of this construction.

In order to adapt the depth of the device to a different draft of the hull 2 to be lifted, it is provided according to FIG. 7 that the entire bearing block 1 with its lateral supports 6 is attached to the inner gusset plates 8 via height adjustment devices 32 . In this way, the diving depth of the pedestal can be adapted to the draft of the hull for each individual hull.
