Abstract

The invention relates to a variable supporting platform (A) for a watercraft (WF), comprising at least one lifting and lowering mechanism (B) and a platform (2) which can be lowered or raised on one side by means of the independent lifting and lowering mechanism (B) such that a ramp is created. Rotary means (10) allow the platform (2) to be put in a slanted position. Additionally, the lowerable platform (2) can be axially retained at a defined distance from the stern (8a) of the watercraft by means of another telescopable platform (22) or actively with the aid of a pushing motor (26).

Description

Presentation of the invention

The invention has for its object to increase the safety of a carrier platform and at the same time to expand the benefits with cost-effective means.

The aboard a dinghy or water jet, called Tender for short, is not easy on the open sea or even with choppy water, because the tender must be precisely maneuvered over the carrier platform and then jacked up accordingly by means of the height-adjustable support platform. To remedy this situation, the support platform is now obliquely placed longitudinally by the asymmetric lowering of the lift arms, so that the tender is driven practically as on land, namely the swimming plate ramp-like high. Stoppers hold the device in place and the ramp can be raised horizontally by lifting one side of the arm and can be hoisted up to the final position with the perfect fit and effortless.

By a position sensor and independently operating lifting means, also the support plate can be kept in a predetermined angular position even when swell.

To the safety in all Hebe, resp. To ensure lowering levels, the variable support platform has Hubverriegelungszylinder, in addition to locking the carrier platform with the vessel in the high position, as well as integrated distance measuring sensors, on the one hand to maintain a certain ramp angle, as well as to stop the stroke at a given lowering height, should a tender - or Wasserjetgerät still be lashed, because without such a precaution, the moored device could be lowered under water. When lowered carrier platform also the gear can not be inserted, respectively. The transverse thruster function is also disabled.

In addition, the carrier platform can be moved axially, or expand telescopically, so that at a given rotation kinematics of the carrier platform arms, the carrier platform is always with a small gap at the rear of the vessel, otherwise there is a gap of more than 0.5 m between the carrier platform and rear of the vehicle the semi-lowered position may grow up. A retractable tarpaulin under tension, fixed on the one hand on the vessel, on the other hand on the support platform, which thereby automatically adjusts the lowering height of the support platform prevents floats come in fully lowered position of the support platform with the propeller blades or rudder or exhaust pipes etc into contact.

But even without a tarpaulin, the lifting kinematics, swimmers, divers and other creatures should not force additional caution, because the lifting arms - especially the parallelograms - are blinded accordingly, so that no one can get in the way. These covers also makes it possible to integrate stabilizing and trimming elements to keep the watercraft, especially at anchor, quieter in the water, as well as having means such as transverse thruster directly integrated, as well as the engine exhaust gases pass through the veneer and these downstream, at a distance from the stern of the vessel, to be carried out again.

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

The core of the invention is, by means of a ramp which can be mechanically locked in any position and to secure the exact ramp angle by Wegmesssensoren, as well as to move the support platform longitudinally to guide the carrier platform with little cleavage from the rear, and the integration of technical Means directly into the lifting arms of the carrier platform, such as transverse thrusters, stabilizing and trimming elements, as well as the underwater passage of the engine exhaust gases.

Further advantageous embodiments of the invention will become apparent from the dependent claims.

Only the elements essential for the immediate understanding of the invention are shown schematically. Way to carry out the invention

Fig. 1 shows a schematic side view of a variable support platform A with a lifting and lowering mechanism B, which by means of a not shown

Linear arm or swivel arm 1 a platform 2, held by a support 3 and a Stützschwenkarm 4, which holds as a parallelogram the platform 2 in the lifting movement - indicated by the arrow H - in a constant horizontal. The swing arm 1 and the support swing arm 4 may be of any shape as long as they do not conflict with the platform 2 during the raising or lowering phase. The swing arm 1 is provided with a lifting means 5, which may be a rotary motor or linear drive and is moved electrically or by means of a fluid. As an example, a fluid cylinder is shown, which has a mechanical Hubverriegelung 6 and a Wegmesssensor 7. The Hubverriegelung 6 ensures that the support platform can be locked in any position. Furthermore, the swivel arm 1 remains mechanically blocked in the event of a fluid failure in its predetermined position. The displacement sensor 7, which may be integrated in the fluid cylinder and e.g. measures linearly or e.g. is also housed on the holding housing 8 in the form of a rotary angle meter, has the task as a limit switch at fully hochgefahrener, resp. completely lowered carrier platform to output a signal so that an electronics stops the fluid pump. The displacement sensor 7 also allows to detect intermediate values in order to safely raise or lower the carrier platform, in double lifting and lowering mechanisms, resp. to move asymmetrically when needed. Furthermore, the distance measurement ensures that when lowered

Support platform of the propeller drive or the transverse thruster can not be operated so that no sudden take-up of the vessel and the variable support platform A could suffer damage, resp. also people who would be on the platform 2. A weighing cell 9 in the region of the swivel arm 2 also warns when the system is overloaded.

In Doppelhebe- and lowering mechanisms is located between the platform 2 and the support 3, a rotating means 10 which serves as a hinge to the asymmetric movement of the pivoting arm 1 to the opposite Swivel arm 1, the tilting movement of the platform 2, as well as the eventual deflection movement, by means of a deflector 11 record.

In addition to the hinged and lockable tender receiver 12, there is the mooring device 13 for the tender C, which has a contact sensor 14, which may be a strain gauge or the like, so that when the platform 2 is lowered below a certain value, e.g. at the level of the water line W, detected by the Wegmesssensor 7, the lowering is stopped until the tender C is released from the mooring 13, so that the tender C can not be lowered under water or only so much that it solves the solution

Mooring 13, the tender C is just floated. In a recreational carrier platform, the lifting means 5 can be designed according to limited power in lowering mode, so that underwater pulling the tender C is also impossible. The tender C can be a dinghy, a jet ski or similar.

In addition to the Hubverriegelung 6 on the pivot arm 6, in addition, a platform lock 15 is used to avoid overburdening loads of the swing arm 1 while hovering the vessel WF hoisted tender C, as well as the platform 2 as possible with defined gap at the rear of the vessel 16 secure, often a

Pre-platform 16 is attached to attach the platform lock 15 and other in it. The platform lock 15 may be electrical or fluidic, and is unlocked via the electronics, while the locking is automatic once the platform 2 has reached its raised end position, similar to a latch of a door lock. A contactor 17 warns against

Non-locking at engine start and can electronically influence the engine management.

For the safety of bathers, but also against pollution and as a carrier of other marine accessories, the lifting and lowering mechanism B by the

Cover 18 blinds, which may for example consist of inexpensive plastic, while the lifting components are made of steel, aluminum or high-strength composite material. Fig. 2 shows a schematic side view of a variable support platform A with a lifting and lowering mechanism B ₁ which has a platform 2 in the interior 19 an axially displaceable, indicated by the arrow X, additional platform 20 and by means of a corresponding linear guide 21, against a Spring element 22 can move. The auxiliary platform presses against a guide rail 23, which can adapt to the line of the watercraft and, for example, is supported on the fore platform 16 and on the stern 8a, so that the support platform as a whole in the lifting movement, indicated by the arrow H, always possible with a small gap leaned against the stern of the boat 8a or if desired at a desired location allows more gap.

It is conceivable that instead of the spring element 22, the additional platform 22 has a guide holder 23a, not shown, which comprises the guide rail 23 and in this way the additional platform 22 axially, on the lifting movement H, is displaceable.

Fig. 3 shows a schematic side view of a variable support platform A with a lifting and lowering mechanism B, which has a platform 2 which rests on an axially displaceable slide 24. The sliding mechanism can be carried out on rollers 25 or Teflon-like coated sliding shoes and is driven by a sliding motor 26 which is carried out electrically or fluidly e.g. via a spindle or push / pull cylinder or the like, supported by an electronic system which, during a lifting or lowering movement of the platform 2, simultaneously or with a time delay, axially displaces the platform 2 by means of an algorithm, according to arrow Y, so that during the lifting or lowering movement or lowering operation of the platform 2, indicated by the arrow H, this a predetermined vertical line V or along a freely definable line S moves along.

It is also conceivable that the platform 2 can be moved by a combination of the telescopically displaceable additional platform 20 as described in FIG. 2 and by means of a sliding motor 26 controlled by an algorithm.

Fig. 4 shows a schematic rear view of a variable support platform A with a lifting and lowering mechanism B with an inclined platform 2, which is achieved by a different lowering of one of the two lifting and lowering mechanisms B. This feature is specific to a tender C used, which runs at a corresponding speed and to let it boast directly to the platform 2. This is particularly important with choppy water or swell, as it may be difficult to position the tender C exactly above the platform 2 and then carefully hoist the device out of the water.

The platform 2 has corresponding tender receivers 12 and stoppers 27, so that the tender C can be brought into position at the ramp entrance and braked in the right place and then only has to be lashed, with the additionally lowered lifting and lowering mechanism B starts up first , then both lifting and lowering mechanisms B parallel to the platform lock

15 start up.

In addition, a position sensor 28 can be placed in the watercraft so that it provides the position values of the watercraft to the electronics and causes the two lifting and lowering mechanisms B to move in such a way that the

Platform against the rolling movements of the vessel horizontally, resp. remains at a certain ramp angle.

Fig. 5 shows a schematic rear view of a variable support platform A with a lifting and lowering mechanism B in the lowered position, with an am

Watercraft or in the front platform 16 integrated roller box 29, in which rolled up or folded an extendable tarpaulin 30 is located, which is connected to the platform 2. When lowering the platform 2, the tarpaulin 30 is thus rolled out or unfolded and thus covers the rear of the vehicle 8a so that swimmers can not come into contact with the propellers 31, in particular with surface propellers, which often have sharp-edged wings. The tarpaulin 30 also protects the floats from rudders, engine exhaust port 32, etc. The tarpaulin 30 may also include an integrated stairway means 33, eg in the form of openings in the tarpaulin 30 or incorporated steps to allow it to get in or out of the water Even with lowered platform 2 is facilitated. The roller box 29 has traction means 34 for tightening the tarpaulin 30, such as a coil spring or motor-driven means, which also retract the tarpaulin 30 when the platform 2 is raised. The tarpaulin 30 can be made of plastic or metal, woven or as blinds or the like. 6 shows a schematic side view of a swivel arm 1 with the cover 18 of a variable support platform A and an integrated trim and stabilization means 35 in order to additionally stabilize the watercraft in the sea state. In the case of gliding vehicles, the trim and stabilization means are above the waterline W and do not cause any resistance during the glide travel.

In addition, the pivot arm 1 can be formed as a hollow body or by means of the cover 18 such that the exiting engine exhaust gases from the engine exhaust port 32, via a channel, not shown, via an inlet opening 36 in the hollow-shaped pivot arm 1 or through the cover 18 are passed through and on the outlet opening 36a enter into the open, indicated by the arrow G. As a result, noise and possible exhaust vortices which could load the watercraft cockpit, for safety's sake moved further downstream.

Fig. 7 is a schematic side view of a pivot arm 1 with the cover 18 of a variable support platform A and an integrated trim and stabilizing means 35, and with an integrated transverse thruster 37 to place the fulcrum of such thruster maximally to the rear and thus better maneuvering to reach, but also to use the considerable installation advantage, namely to drill no more mounting holes in a vehicle rear 8a and to connect the supply and discharge lines for operating the Querstrahlruders 37 together with the inlet and outlet of the lifting means 5 and through a single perforated plate in the rear of the vehicle 8a perform. The assembly of the transverse thruster 37 can also be done elsewhere on the pivot arm 1, indicated by the dashed lines, so that the thrust of a transverse thruster

37, which pass through the thrust jet, often by one or more pivot arms 1 in the way and massively reduce the transverse thrust, pass through smoothly.
