Description

Lowering and securing means on a watercraft

Technical area

The invention relates to a slide-controlled lowering and securing means, to a lowerable swimming platform or and stairs or and ladder at the stern of a watercraft, according to the preamble of the first claim.

State of the art

Lowerable platforms, especially for swimmers, divers and for tender vehicles, are known as described in the patents DE 19602 331, US6327992, US5690045. These deaerate people or material comfortably to water or to include on board.

Stairs or ladders on bathing platforms are widely used, with fold-out versions as described in US Pat. No. 4,733,753 or US Pat. No. 2206/0075952 A1 also being described.

Presentation of the invention

The invention is based on the object, at a watercraft, which has a height-variable platform means and horizontally, respectively. tiltable can be lowered or comprises a ladder means as auxiliary or emergency climb for persons, these have a carriage on which a platform part, or stairs or ladder is supported and serves as a basis for the kinematics for height adjustment and securing the means.

In today's fast glides, there is still great vertical loads on the vehicle body despite strong upheaval of the hull in rough seas. Thus, at the rear of the lowerable platforms and stairs means corresponding forces are exposed, also the means of action, especially if there is little space at the rear and they can not support correspondingly wide. In addition, people are fast in the water, but may not come so easily on the high and smooth hull walls back on board. A quick and easy to pull out, but still well locked against wave waves stairs is a great advantage.

The increasing popularity of lowerable platforms, the invention comes a kinematics with a rigid, rotatably mounted support rod with a horizontal slide very contrary, since in this configuration, the waves do not hit directly on the active cylinder, also the Wirkzylinder example. elegant and space saving in a side part, resp. just below the platform.

Thus, a platform can perform a dual function, despite different

Tilting curves of two different means, which additionally serves as a steering aid and holding means by means of the carriage. The controlled slide thus allows many applications, be it as an active, as a passive kinematics as well as fuse element.

The ladder, which is advantageously mounted underneath the bathing platform, comprises a guide rail on the platform which carries and can push out the ladder and, with the correspondingly positioned deflecting means, allows the ladder to tilt simultaneously during extension. This is a crucial difference in emergency situations compared to the commercially available ladder versions, which are executed first completely horizontally and then practically suddenly tilt down and often are not held by a working cylinder after dumping, which is a particular problem in waves. The active cylinder can be an active, for example by means of a command output to a hydraulic unit, which is virtually depressurized when not in use, so by muscle power ladder can still be pulled out at any time, or a passive working cylinder, such as a pilot-operated gas cylinder, with the same advantages, namely If necessary, extend the ladder quickly and safely by hand.

Central is the recovery of the platform or ladder in the event of a technical breakdown, whether due to a failure of the pump, be it a valve problem, by means of pressure switch the system takes over a gas cylinder or accumulator as pressure accumulator the return of the platform in its rest position.

According to the invention this is achieved by the features of the first claim.

The essence of the invention is to improve on a height-adjustable swimming platform or stairs or ladder, by means of a carriage, the kinematics for lowering these agents or to enable a dual function of a means by the carriage exerts a supporting or guiding function and this of a rotatably mounted rigid rod is supported, so that vibrations caused by the swell do not directly affect the active cylinder, as well as an emergency ladder, which can maintain their position even with pressure release of the action cylinder in each case. A retrieval by redundant means ensures safe recovery of the platform or ladder even in technical unforeseen.

In the figures below the Aufklimmung the watercraft is not shown.

Way to carry out the invention

Fig. 1 shows a schematic side view of the tail 1 of a watercraft with a hinge 2, which is connected to the platform 3 and tipping the

Platform 3 allows. The platform 3 is in the horizontal position by means of a carriage 4 which can be stored in the guide rail 5 and move there along and on which a rotatably mounted position rod 6 is fixed, which is supported on the rear 1 and is held in position. The active cylinder 7 is located between the position rod 6 and the rear 1. By extending the working cylinder 7 by means of the piston rod 45, the carriage 4 is extended and since this is connected to the rotatably mounted position rod 6, the latter performs a rotational movement and leads to a corresponding Slope according to arrow N of the hinged on the hinge 2 platform 3. This can thus z. B. be tilted below the waterline WL.

On the surface of the platform 3 there may be an anti-slip coating, as well as a staircase pattern, or there may be recessed rotatable stair elements, e.g. be controlled by a parallelogram or electric motors and the like, which always remain in tilting the platform 3 in the horizontal position. Of course, the platform 3 can also serve as a simple ramp for pulling up or lowering a tender boat or jet skis.

Fig. 2 shows a schematic side view of the tail 1 of a watercraft with an attached tiltable platform 3 with a non-slip surface and a fold-out staircase 8, which can be folded out as needed weightless according to arrow T by means of the stair hinge 9 and gas pressure damping 10 and in the Swell the stairs 8 opposite the watercraft also keeps as calm as possible. Instead of manually extend the stairs, this can be done by means of a hydraulic or electric Ausklappwirkmittel 10a. The horizontal

Positional position of the platform 3 is effected by means of the carriage 4 mounted in the guide rail 5, on which the position rod 6 is rotatably mounted and additionally by means of the lock 11, which penetrates into the carriage 4, this is thus held in the selected position. The tilting of the platform 3 takes place on the one hand on the release of the lock 11, wherein the platform 3 is now on the rotatably mounted telescopic cylinder 12 comes to rest and this in turn is supported on the buoyant body 13. The buoyant body 13 is connected by means of the flap hinge 14 with the rear 2, where the active cylinder 7 is mounted, wherein the opposite side of the active cylinder 7 is connected to the buoyant body 13. Now, if the active cylinder 7 is extended via the piston rod 45, the buoyant body 13 tilts according to arrow K and thus leaves the platform 3 on the telescopic cylinder 12 also tilt downwards, according to arrow N. The telescopic cylinder 12 advantageously has a damping, so that the partially submerged platform 3 does not simply hang freely in the water, but a viscous connection between the platform 3 and buoyancy body 13 is made, which means a considerable advantage at sea. The telescopic cylinder 12 deafened another function, namely, the lock 11 is engaged in the carriage 4 and thus blocks the tilting tendency of the platform 3, the buoyancy body 13 can perform the function of a trim flap and the telescopic cylinder 12 goes the way indicated by arrow K of the buoyant body 13th passive with. The telescopic cylinder

12 may be rotatably mounted so that it can follow the vertical axis of the inclined position of the buoyant body 13, according Aufkimmung the watercraft. Instead of a telescopic cylinder 12, it is also possible to use a rigid support element 12a which has no connection element to the platform 3, so that when the lock 11 is released, the platform 3 is supported on this support element 12a. A separate damping means 15 can be placed between the platform 3 and the tail 1 and thus help reduce loose rocking of the platform 3 in the sea state accordingly. The lock 11 may be a clinker lock, so that the complete startup of the platform 3, this ultimately engages in the lock 11 and thus the platform 3 is automatically locked until the lock 11 is released manually or via a small active cylinder again.

Fig. 3a shows a schematic side view of the tail 1 of a watercraft with a parallelogram 16 attached thereto, consisting of the pivot arms

16a and 16b, which is attached by means of a carrier 17 to the bifunctional platform 3a. At the rear 1 is a releasable hinge 18, which is held or released by the hinge release 19. When the hinge release 19 is released, the bifunctional platform 3a moves due to the parallelogram 16 and the active cylinder 7 attached thereto and activated, like any other lowerable swimming or tender platform, horizontally downwards. This is advantageous when larger and heavier tenders or jet skis are lifted on board or lowered into the water accordingly. Not shown are the covers of the pivot arms 16a, 16b to shear and crushing points for the float to avoid. An additional prevention of such accidents is the inclusion of side barriers 23, which are fixed on both sides of the parallelogram 16 vertically below the platform 3a. Also, the floating bodies associated with the platform are not shown which produce static buoyancy at anchor and dynamic buoyancy while riding. Not shown here, but described in Fig. 3b, indicates the bifunctional platform

3a comprises a plurality of segments which are connected via e.g. a separate parallelogram, take effect as needed. The segments are held in a parallelogram, which has a rotatably mounted stair carriage 21 and guided in a stair guide rail 20.

3b shows a schematic side view of the stern 1 of a watercraft with a parallelogram 16 attached thereto, consisting of the pivoting arms 16a and 16b, which is attached by means of a carrier 17 to the bifunctional platform 3a. At the rear 1 is the releasable hinge 18, which is held or released by the hinge release 19. If the hinge release 19 is in the "closed" position, only the frame 22 moves horizontally downwards with the carrier 17 of the bifunctional platform 3a due to the parallelogram 16 and the active cylinder 7 attached and activated thereon The holding parallelogram 24 located in the frame 22 is on the one hand The holding parallelogram 24 has on the opposite side of an equal part, with the segments 25 are therebetween, which due to the parallelogram and their connection according to the prior art, when pivoting the Halteparallelogramms 24th According to arrow P, instead of using a classical parallelogram, an electric servomotor or a hydraulic system can ensure the horizontal position of the segments 5. The pivotal movement line of the holding parallelogram 24 is different from that of the parallelogram 16 according to the arrow N, sod ass the stair carriage 21 is forcibly moved along the Halteparallelogramm 24 in the stair guide rail 20 in the longitudinal direction. The segments 25 serve as stair steps, if possible as closed bodies or at least on the side facing the foot a stair cover 26 so that no one can get between the segments 25 with the foot or another limb, especially when the bifunctional Platform 3a. The bifunctional platform 3a has the

Advantage that this serves as a lifting platform for tenders and the like on the one hand, on the other hand, a welcome, safe staircase that allows people comfortably the way into the water or out of the water.

FIG. 4 shows a schematic top view of the tail 1 of a watercraft with the bifunctional platform 3a. There is the releasable hinge 18, which is held or released by the hinge release 19. On one of the segments 25 is the Tenderaufnahme 27, which consists of a V-shaped V-frame 28 with a Aufkimmung, which corresponds to that of Tenders or Jetskis. The V-frame 28 has a rotating means 29 and is rotatably mounted fixedly connected to the segment 25. At one end of the V-frame 28, a fixing means 30 is mounted, which can be connected to a counterpart 31a in the segment 25 or with a counterpart 31b in another segment 25. The position shown here of the two V frame 28 deafened the recording and attitude a tender on the bifunctional platform 3a. The fixing means 30 is fixedly but releasably connected to the counterpart 31a, which is e.g. may be a depression in the segment 25. In counterpart 31b is the sensor 32, which notifies the controller 33 that the V-frame 28 is connected via e.g. three segments across and the fixing means 30 in

Counterpart 31 a is anchored and that at the same time by means of an additional sensor 34, the releasable hinge 18, respectively. the hinge release 19 is opened, so that the bifunctional platform 3a is lowered horizontally at command, as the entire bifunctional platform 3a. If the lowering command for the bifunctional platform 3a switched to the

Stair position, this can only be done by means of a pre-releasing the fixing means 30 and rotating the V-frame 28 by 90 °, as well as fixation of this in the counterpart 31b, as well as ensuring that the releasable hinge 18 is locked by the hinge release 19 , If this safety function was not used, the staircase function could be activated would be damaged in transverse V-frame 28 and thus the V-frame 28 and the segments 25 would be damaged.

The V-frame 28 can also be laid flat when not in use, so that the corresponding segment 25 is not a tripping element. The tender can be secured to the eyelets 35 by means of straps on the bifunctional platform 3a.

Fig. 5 shows a schematic side view of the tail 1 of a watercraft with a platform attached thereto 3 and an underlying ladder 36 with its rungs 36a, attached to the carriage 37 and guided in the conductor guide rail 38, wherein the conductor carriage 37 or conductor 36 of the active cylinder 7 attacks, which is supported on the rear 1. By extending the piston rod 45 on the active cylinder 7, the conductor carriage 37 moves with the conductor 36 in the conductor guide rail 38, wherein the conductor 36 is additionally guided by the deflector 39. The deflector 39, which is located at the running of the conductor guide rail 38 deliberately below this, is rotatably mounted on the platform 3 and has two guide rollers 40 which guide the conductors 36 and carry. By extending the conductor 36 forcibly changes the angular position of the conductor 36 to the lower deflector 39 and thereby the conductor 36 tilts when extending continuously towards water.

By means of the command keyboard 41, e.g. a fluid unit 42, are activated and thus let the active cylinder 7 on or extend. If the conductor 36 is in the rest position, i. lying under the platform 3, the fluid assembly 42 can be placed without pressure by means of a controller 33a, so that in case of need, a person in the water can take the overlying the waterline WL conductor 36 and according to

Pull arrow NN downwards. Due to the tensile force which acts on the active cylinder 7 via the guide carriage 37, the fluid in the working cylinder 7 flows into the tank 42a and the conductor 36 can be brought out and bring about its use. Another possibility of pressure release in the active cylinder 7 is a built-in fluid line 46 check valve 43, which opens from a certain load, so that the

Fluid is diverted into the tank 42 a and thus the active cylinder 7, respectively. the piston rod 45 releases. It is also conceivable to let the conductor guide rail 38 rise to the rear at an angle X, so that the conductor 36 always leans against the front stop Y. Another possibility is to use a disengageable gas pressure cylinder 7a, which keeps the position despite shaft stop and vibration at the stern 1 of a watercraft by the blocking device holds. The gas pressure cylinder 7a is unlocked only by the release lever 44, for example, by the person in distress engages the transverse release lever 44 on the conductor 36 and pulls together with the conductor 36, this is unlocked and thus can the ladder 36 comfortably take off. It is also conceivable to attach a second command keyboard 41 instead of the unlocking lever 44, which thus also provides the desired benefit.

Fig. 6 shows a schematic side view of the tail 1 of a watercraft with a hinge 2, which is connected to the platform 3 and a tilting of the

Platform 3 allows. The platform 3 is in the horizontal position by means of a carriage 4 which can be stored in the guide rail 5 and move there along and on which a rotatably mounted position rod 6 is fixed, which is supported on the rear 1 and is held in position. By extending the effective cylinder 7 by means of the piston rod 45, the carriage 4 moves out. If, for technical reasons, the fluid assembly 42 fails, the pressure in the fluid line 46a can be depressurized by activating the neutral valve 47, the storage valve 48 being opened at the same time, so that the reservoir 49, which permanently pressurizes the system pressure via the fluid line 46b is set up, a pressure and a volume flow V can be activated, which fills the active cylinder 7 and lifts the platform in the position S. Instead of this variant, a gas pressure cylinder 7b can be activated automatically, which is attached to the platform 3, which acts on the carriage 5, or carrier 17, or position bar 6, it may have the effective cylinder 7, this should not be completely depressurized by means of of the neutral valve 47 are completely depressurized and if this is not possible, the active cylinder 7 must be posted by the cylinder lever 50, so that the active cylinder 7b the thrust without hydraulic jam, on the carrier 17 or position rod 6 acts and the platform 3 according to stroke H in the position S lifts.

Unlike other hoists, in normal operation to drive the platform 3 down, in the latter variant, the working cylinder 7 to work against the gas cylinder 7b, just as in the platform 3, which has floats. If no storage valve 48 is provided, then the active cylinder 7 must work against the memory 49 to lower the platform, but only perform passive work when lifting the platform 3.

Of course, the invention is not limited to the embodiments shown and described.
