Description

The The present invention relates to a watercraft having a hull and with a height-adjustable platform and with a Stair with steps from a boat deck to the platform.

Watercraft, like sailboats or motor yachts, have over a hull with a deck. Preferably in the stern area of the fuselage can be designed as a deck or as a platform Bathing platform can serve. Likewise on this platform one can Dinghy be carried in a corresponding bracket.

to Improvement of the possibilities of use of such Platform it is known that the platform, for example, over a hydraulic lifting device, designed height adjustable is. Thus, the platform can be under the water surface lowered to let a dinghy to water or to with to drive the dinghy over the platform and by lifting the platform to lift the dinghy out of the water.

Around The platform is safe and comfortable even when lowered Deck can be accessed from the fuselage stairs or ladder with several steps to be arranged to a height difference between the deck and the lowered platform to overcome.

Such a height-adjustable platform on a watercraft body is from the WO 03/106254 A1 known. The platform is articulated via pivot arms on the fuselage, for example, by means of the height-adjustable platform to let a dinghy to water or to lift out of the water. Between the two pivot arms while stairs are arranged to form a staircase, which in turn turn depending on the pivoting angle of the pivot arms to always form horizontal steps. The steps are rotatably mounted on the pivot arms. A disadvantage is to be considered here that results in unfolded and lowered platform in the region of the upper end of the stairs an uneven, rugged surface, which leads to tripping people when walking. As a deck area, this area is practically unusable.

Furthermore, the disclosure EP 1 854 715 A1 a telescopic gangway on a watercraft hull. Within a box-like cavity an extendable and foldable staircase or ladder is arranged with several steps, the box to compensate for a height difference, for example, to a quay wall, even height adjustable. This gangway serves either to make a walkable connection between the vessel and the land or as a ladder leading from the watercraft into the water. The gangway protrudes freely and is actively adjusted by means of adjustment in their orientation. This makes it technically complicated and has a high weight.

Finally, the reveal GB 430 188 as well as the US Pat. No. 1 215 827 Ship ladders or stairs, which are pivotally mounted at a first end on the watercraft body and the second end may rest, for example, on a quay wall or pier. In this case, the respective stair steps are pivotable relative to the stair or ladder cheeks, for example, depending on different water levels still keep substantially always horizontally aligned steps.

For The present invention therefore has as its object, a watercraft of the type mentioned above to improve that a Stair space and weight saving is realized while being easy manageable and versatile.

The Solution to the problem succeeds according to the invention that the stairs at a first end on the watercraft fuselage articulated pivotally and at a second end relative to the height adjustable Platform is movable.

at such a trained vessel serve the lateral Cheeks of the stairs or ladder not itself as a lifting mechanism for the height-adjustable platform form. Rather, the second, free End of the stairs, preferably as described below, even loose on the platform, so in particular no fixed and / or have a supporting connection with this platform. Thereby It is possible to build a much lighter structure Stair to choose, since the stairs only the weight of a they must wear the person using them and not the weight of the whole Platform and possibly a dinghy when lifting and lowering. Here, the first end of the stairs is pivotally so on the watercraft hull in Area of the platform arranged that the stairs with their second End can be placed on the downwardly adjusted platform. Here is the second, free end of the stairs on the surface of the Platform supported and relative to the platform respectively on the surface of which is freely movable in one direction, the in the plane of the platform and at right angles to the pivot axis of the pivotal connection between stairs and watercraft runs.

The advantage of the invention is, in particular, that the stairs are relatively light, ie designed with a considerable weight saving can, so that the weight of the staircase, for example, when arranged at the rear of the vessel, its performance does not affect. Also, such a staircase can be stowed away to save space.

preferred Embodiments of the invention are the subject of the dependent claims.

In Preferably, the stairs are each to the side walls the stairs are rotatably mounted to these during a height adjustment of the platform each a substantially horizontal Alignment of the steps during the entire height adjustment maintain. Suitable means for this are, for. Scissors or pantograph or parallelogram mechanics.

to Reducing an accident risk is on the stairs, at least on one side, preferably on both sides, a lateral handrail provided, which has a similar mechanism as described above when lowering the platform with extended or unfolded can. When lifting the platform, the handrail folds automatically.

In a first embodiment, the staircase is designed such that in the raised state of the platform, the stairs are flush with their stairs with a surface of the platform completes. The means that the rotatable relative to the side walls of the staircase Stair steps dimensioned and arranged relative to each other are that they in turn are essentially continuous and flush with the surrounding surface of the platform make up the final surface when the platform maximum is raised. In this position, the platform is preferably flush with the deck of the vessel, so that a step-free enlarged deck surface is reached. Is the height-adjustable platform increasing lowered, so the individual steps remain essentially level; by pivoting the rigid side walls However, the staircase they receive each seen in the vertical direction a separate arrangement in order to be partial or complete lowered platform to form a walk-in staircase.

to Recording of the stairs in the raised state of the platform in which the staircase is not needed is in the surface the platform provided a correspondingly sized recess.

at this embodiment, the second, free end of the stairs is preferred in a linear guide in or on the platform, z. B. inside the recess, guided. For example, they work Castors at the free end of the stairs with a correspondingly designed Guide rail or groove integrated into the platform is, together.

In an alternative embodiment is in the watercraft fuselage Staircase drawer designed to hold the stairs. It is it is included in the invention with that the side cheeks of Stairs formed as an elongated and rigid component or the stairs themselves foldable in their longitudinal direction or telescopically designed telescopically. Are the side cheeks rigid components, so is the stair in the inserted state in their longitudinal direction substantially horizontally aligned and the individual, relative to the side walls pivotable steps can also be a substantially flush and form continuous area. To use the stairs this is pulled out of the staircase drawer or pushed out and its free end is on the surface of the height-adjustable Platform filed. When lowering the platform is a pivoting the staircase relative to the watercraft fuselage on the pivoting Storage of the first end of the stairs, for example on a stair guide slide in the staircase drawer.

The Staircase drawer can be integrated into the fuselage such that in the raised state of the platform facing the platform open side of the staircase drawer covered by the platform is. Thus, there is no separate closure for the staircase drawer necessary. To use the stairs here is the platform initially lowered a bit; following can the stairs pulled out of the then open staircase drawer and at its first end, pivotally connected to the hull is to be pivoted to the second, free end of the stairs to deposit the surface of the platform. Below can the platform will be completely lowered, taking the stairs swung automatically under their own weight and the stairs preferably always a horizontal orientation maintained.

In An alternative embodiment proposes that the staircase drawer in a raised state of the platform above the surface the platform lying height is arranged. Thus, can the stairs also in the raised state of the platform from the staircase drawer pulled out and inserted into this.

in this connection It is preferred that the free end of the stairs be loose on the surface the platform rests in the simplest possible way a low-resistance relative movement between the surface to get the platform and the free end of the stairs.

Prefers are doing resistance reduction at the free end of the stairs Rollers or skids provided.

It It is understood that the taking off and pushing in of the stairs the or in the staircase drawer also by means of a power drive, For example, electric motor or hydraulic, can be done. The lifting and lowering of the platform is usually done already because of the weight by a power drive in the lifting device, preferably hydraulically. Furthermore, the height-adjustable Platform and the pivoting staircase with sensors or other Safety devices must be equipped to ensure their proper functioning and record and monitor their respective positions can and thus injury hazards to users to exclude the stairs and the platform.

in the Following are three embodiments of the invention explained with reference to a drawing. The figures of the drawing demonstrate:

1 to 3 a platform with integrated stairs, in perspective view,

4 to 7 a platform with stairs and a covered staircase drawer, in longitudinal section, and

8th to 12 a platform with stairs and a staircase drawer on deck, in perspective view.

In the 1 to 3 each is a height-adjustable platform 1 shown, which has an arbitrarily configurable and here only schematically indicated lifting device 2 , like lifting hydraulics, on a watercraft hull 3 height adjustable is attached. In the surface 4 the platform 1 is a staircase 5 with rigid sidewalls 6 and relative to rotatable steps 7 integrated. This is the first end 8th the stairs 5 in the sense of the double arrow S pivoting on the fuselage 3 stored and the second end 9 the stairs 5 is as a staircase relative to the platform 1 freely movable, as indicated by the double arrow F. It may be the second end 9 the stairs 5 either loose on the platform 1 rest or it is a linear guide, for example in the form of rollers at the second end 9 and a guide rail or groove on the platform 1 , intended. The platform 1 has a recess 10 for receiving the stairs 5 in the raised state of the platform 1 how he looked 1 is apparent. Here is the stairs 5 with their steps 7 dimensioned such that the stairs 7 with the side wall 6 essentially flush with the surface 4 the platform 1 to avoid stumbling.

Furthermore, at the stairs 5 a handrail 11 , preferably on both sides of the stairs 5 each own handrail 11 , Be provided, the automatically when lowering in the direction of arrow H and folds. Appropriate Me chaniken for pivoting the stairs 7 or for unfolding the handrail 11 are known in the art.

In 2 is the platform 1 Shown in half lowered state and in 3 in fully lowered condition. The stairs 5 Adjusts automatically in its inclination of the position of the platform 1 on, with the steps 7 always stay aligned horizontally.

Another embodiment is in the 4 to 8th played. It is in the fuselage 3 a staircase drawer 12 for receiving the stairs 5 educated. In this version is the staircase drawer 12 like that in the hull 3 integrated that staircase drawer 12 from the platform 1 is covered in its raised state, as seen from 5 is apparent. Will now be according to the 6 the platform 1 lowered a bit in the direction of H, can the stairs 5 either manually or by means of a power drive from the staircase drawer 12 pulled out or pushed out, as is illustrated by the double arrow T. In 7 is the platform 1 completely lowered, leaving the stairs 5 to below the waterline 13 enough and the platform 1 For example, can serve as a bathing platform.

This is the second, free end 9 the stairs 5 as a staircase loose on the surface 4 the platform 1 and may be equipped with rollers or skids to reduce frictional resistance. The free end 9 is in the direction of F relative to the surface 4 the platform 1 movable.

For easy removal and insertion T of the stairs 5 may be the first end 8th the stairs 5 on a staircase slide 14 be rotatably supported in the sense of the rotary arrow S. The stair guide slide 14 For example, in a corresponding guide rail in the interior of the staircase drawer 12 be stored. To reduce the sliding resistance can be on the stairs 5 as well as the stair guide slide 14 roll 15 or the like may be provided.

Finally, in the 8th to 12 a third embodiment shown in which the staircase drawer 12 is arranged at such a height that it is in the raised state of the platform 1 still above the surface 4 the platform 1 lies. So here also in the raised state of the platform 1 the stairs 5 in the direction of T from the staircase drawer 12 pulled out and in this will be inserted. The staircase drawer 12 forms a staircase on the deck 16 ,

In 9 is the stairs 5 partially undressed and in 10 she is completely undressed. In 11 becomes the platform 1 lowered in the direction of H and the handrail 11 at the stairs 5 straightens up automatically, with the steps 5 always aligned horizontally. The free, second end 9 the stairs 5 lies loosely on the surface 4 the platform 1 and moves in the direction of F. In 12 is the platform 1 completely lowered. The first end 8th the stairs 5 is in the direction of the arrow S pivotally on the fuselage 3 stored.
