Abstract

The gangway has stairs (7) fastened on a baseplate and pivotable around 180 degree in a working position, where the gangway is built into a platform (3) of a lifting loading platform (2). A gangway rotational axis lies in a longitudinal axis of a yacht (1). The stairs are connected pivotably indirectly or directly by a stair axle (12) with the baseplate and are moved in the longitudinal axis of the yacht. The stairs are pressed by a stair longitudinal spring (10) against a quay wall (21), where the stairs has a stair support (9) at an upper end.

Description

The invention relates to a gangway for watercraft for installation in or attachment to a watercraft, with a walk-on bridge and / or stair section. Via a gangway, people should be able to safely, simply and easily board a vessel or leave the vessel. The gangway thus "connects" the watercraft, which is typically a pleasure craft, in particular a motor yacht, with a pier, quay wall or a fixed dock at a port facility.

Especially for smaller vessels wegnehmbare steps, ladders or stair sections are common means to get from the boat to land or vice versa can. For larger vessels, especially larger motor yachts, mechanically or hydraulically ausbringbare gangways are known. These gangways, when not in use, are generally transverse to the direction of travel of the craft and significantly affect the design of the craft. In addition, it turns out to be a considerable effort to securely secure these gangways or stowed when the vessel leaves the port.

It has also been proposed to stow larger gangways, which can easily be more than 4 m long, in a tunnel-shaped, so from the outside not visible recording. This requires a lot of space, which is not available for other purposes.

The present invention has for its object to provide a gangway whose placement on the vessel as little as possible affects the design and visual appearance of the vessel. The gangway should also be safely accessible and preferably give the user a walking comfort.

This object is achieved in a gangway of the type mentioned in the present invention that the walk-on bridge and / or stairway section is arranged on a base and the base base together with the walkway and / or stairway section to substantially 180 ° about a Gangwaydrehachse from a stowed position in a working position is pivotally, from which the walk-on bridge and / or stairway section with respect to the base in a walk-in position of use can be brought.

The solution according to the invention is characterized in that the gangway no longer has to be assembled and disassembled as a whole and stowed away at another location. The gangway is brought to a certain extent only by a pivoting movement through 180 ° from its stowed position to its working position, the gangway in the stowed position either optically not visible or at least housed below a walk-in area of the watercraft. If the gangway is pivoted from its stowage position by 180 ° in its working position, so can the walk-bridge and / or stair section bring in his walk-in position of use and in particular upright. Depending on their size, the deck level of pleasure craft is typically between 600 and 1200 mm above the waterline. Quay walls are typically at least 1 m above the water level. In most cases, a gangway therefore requires starting up or standing up to the quay wall, starting from the vessel. Therefore, it proves to be advantageous that the walkable web and / or stairway portion, starting from the working position with respect to the base base in a walk-in use position erectable, in particular with respect to the base base is pivotally upwards. It proves to be advantageous if the walk-web and / or stair section extendable, in particular telescoping, so that its use length is greater than its length in the stowed position. For this purpose, the web and / or stairway section may comprise a plurality of telescoping and extendable sections.

Furthermore, it proves to be advantageous if the side facing away from the walkway and / or staircase side of the base base forms a preferably walk-surface of the watercraft. Thus, if the gangway is in its 180 ° pivoted position in the stowed position, according to this variant of the invention, the base base forms a surface of the watercraft. The basic base is then preferably flush in the adjacent navigable surface of the vessel over. In this respect, it proves to be advantageous if the base base is formed on its side facing away from the walkway and / or stairway portion side corresponding to the adjacent surface of the watercraft, optionally with the addition of suitable walk-surface forming means.

In a further development of this inventive idea of particular importance, it proves to be advantageous if the preferably accessible surface of the watercraft is the accessible surface of the platform of a tail lift of the watercraft. The gangway invention is integrated according to this inventive idea in the tail lift of the watercraft. The term "tail lift" is intended here to designate an arbitrary walk-on device with a liftable and lowerable platform on a watercraft, which device is typically provided on the aft stern of the watercraft and preferably on the outside of the watercraft. The platform can also be lowered below the water surface, so that it can serve as a swimming or bathing platform.

The aforementioned gangway axis of rotation could be oriented to the longitudinal central axis of the vessel per se in any direction; However, it proves to be advantageous if the gangway axis of rotation is extended in the direction of a longitudinal center axis of the watercraft. Since the gangway itself typically has a greater longitudinal extent than its width, the arrangement of the gangway axis of rotation in the direction of the longitudinal center axis of the vessel proves to be advantageous insofar as the moment of inertia of the pivotable gangway arrangement are reduced in such cases can. However, it would also be conceivable to provide an additional rotatability of the walkable web and / or stairway section about a vertical axis, so that the gangway with its greater longitudinal extension could also be arranged so as to be pivotable about a gangway axis of rotation lying transversely to the longitudinal central axis of the watercraft. It would then, after it has been swiveled by 180 ° in the working position, additionally rotated by 90 ° in the ship's longitudinal direction to be brought from here to their position of use.

So far, the arrangement of the gangway axis of rotation with respect to the base has not been discussed. The gangway axis of rotation could, at least in principle, be provided on one longitudinal side of the base base, so that the base base is pivoted to a certain extent like a flap on the adjoining surface of the watercraft or on the platform of the tail lift. However, it proves to be further advantageous if the gangway axis of rotation is centered with respect to the base, so that an opening in the vessel, in particular in the platform of a tail lift of the vessel, in both the stowed position and in the working and use position of the gangway the base is concealable. Also in this case, it proves to be advantageous if the base base or a base plate of the base base forms the preferably walk-surface of the watercraft.

In a further embodiment of the invention, it proves to be advantageous if the walk-step section has parallelogram horizontal steps. Thus, these steps always have a horizontal extent in both lower and more upright position of the gangway. This proves to be especially advantageous if the relevant stairway section with the base base is pivotally connected to a horizontal in the working or use position stairway pivot axis.

The walk-on bridge and / or stairway section could be arranged in any desired manner and, as mentioned above, preferably pivotably on the base base. According to a further inventive concept, it proves to be advantageous if the walk-on bridge and / or stairway section is arranged longitudinally displaceable relative to the base base. In this way, a distance between the free end of the web and / or stairway section and a quay wall could be reduced by longitudinal displacement of the web or staircase section relative to the base so that the web or stairway section can be applied to the quay wall or a distance between the end of the web or stairway section and the quay wall can be reduced. In this case, an embodiment proves to be advantageous in which the walk-on bridge and / or stairway section both arranged longitudinally displaceable on the base base and with respect to the base base up and / or down pivot.

For the longitudinally displaceable arrangement of the web and / or stairway section, a longitudinal guide means is arranged between the walkable web and / or staircase section and the base. This longitudinal guide means may be formed, for example, in that on the base base on both sides of an elongated slot-like acting recording is provided. In a further development of the inventive idea of the longitudinally displaceable arrangement of the web and / or step section, it is proposed that this be biased with respect to the base base in a direction of displaceability, in particular in the aft Direction. In this case, the walk-on footbridge and / or stairway section is moved in the direction of the quay wall without the need for costly measures.

Furthermore, it proves to be advantageous for erecting, in particular for pivoting, the walkable web and / or stair section into the position of use, and / or for longitudinal displacement of the walkable web and / or staircase section, a power drive, in particular a pneumatic or hydraulic cylinder, a linear drive or another motor drive is provided.

The aforementioned power drive acts in the broadest sense between the base and the walk-bridge and / or stair section. It is preferably also arranged between these components. According to one embodiment of the invention, however, the power drive is supported towards the base base on a longitudinally displaceable relative to the base plate on which the web or stairway section is arranged.

Furthermore, it can prove to be advantageous if the walk-on bridge and / or step section is movable back and forth transversely to the gangway axis of rotation and parallel to the plane of the base base with respect to the base base, so that a certain floating support of the web and / or stairway section is provided , It proves to be advantageous in development of this invention, if the walk-on bridge and / or stairway section is biased transversely to the gangway axis of rotation relative to the base base by transverse spring means in a central position.

Furthermore, it proves to be particularly advantageous if the base of the gangway is secured by an anti-rotation means in the stowed position and in the working and use position against rotation about the gangway axis of rotation. This anti-rotation means may advantageously comprise bolts.

The accessible walkway and / or stairway section can be further advantageously provided with a hinged and / or plug-in railing.

The present invention also relates to a watercraft with a tail lift with a walk-platform and with a gangway according to one or more of claims 1-15, wherein the gangway is integrated into the platform such that the side facing away from the walkway and / or staircase portion the base base forms part of the walkable surface of the platform.

The inventively designed and integrated into the vessel gangway offers the highest level of safety and comfort. Therefore, this gangway also offers older and less well-groomed people a safe route to the watercraft.

When not in use, the gangway disappears completely. It does not affect the design of the craft nor does it consume usable volume of the hull of the craft when installed in the platform of a tail lift.

The fact that the gangway or its base simultaneously forms part of the accessible surface of the watercraft or the platform of the tail lift and the essential components can be made of aluminum, results in a very favorable weight balance.

In conjunction with a tail lift, the gangway can be integrated into the platform of the tail lift by the manufacturer and therefore cost-effectively. All power drives, such as pneumatics and / or hydraulics, as well as the required electrical system can be easily integrated into the tail lift and supplied by the central unit and control. After attaching the tail lift to the watercraft, especially a pleasure boat, the gangway is ready to work immediately.

Further details, features and advantages will become apparent from the appended claims and the drawings and the following description of a preferred embodiment of the invention. In the drawing shows:

FIG. 1

FIG. 6

a perspective view of the vessel after FIG. 1 with the gangway in a position of use.

FIG. 1 shows the stern of a watercraft in the form of a motor sports boat or yacht 1 with a tail lift 2 and their platform 3 and the yacht-side platform approach 3 '. In the middle of the platform 3, the underside of a still to be explained gangway 16 can be seen, which is housed in an opening 25 of the platform 3. It is part of platform 3 after installation.

FIG. 2 shows a sectional view of the platform 3 in the area of the gangway 16 in their unused stowed position. The platform 3 of the tail lift 2 comprises a support plate 4, on which a suitable top covering 5 is applied, which forms a walk-on surface 24 of the yacht or the platform 3. The same topping 5 is replaced by the FIG. 1 apparent bottom of a base 19 of the gangway 16. The gangway 16 is mounted in a Gangwaydrehachse 17 whose flight coincides in this embodiment with the longitudinal axis 26 of the yacht 1.

FIG. 3 is analogous to FIG. 2 but with the gangway 16 swiveled 180 ° into its working position. This is the first step in the commissioning of the gangway 16. In the positions after FIGS. 2 and 3 is the gangway 16 with locking bolt 18 as anti-rotation means 32 ( FIG. 5 ) secured.

FIG. 4 shows the top view in the direction of arrow IV in FIG. 3 , When driving the watercraft, when the gangway 16 in the in FIG. 2 shown stowed position, and also in the working position and in the use position in the application of the gangway 16 this is fixed on the mechanically or motor-operated gangway locking bolt 18 to the platform 3.

The base 19 of the gangway 16 comprises a base plate which, like the platform 3, preferably consists of aluminum extrusions. With respect to this basic base, a longitudinally displaceable plate 23 is provided, with respect to which the web and / or stairway section 7 of the gangway 16 is articulated (in FIG FIGS. 2, 3 not apparent).

FIG. 5 shows the aft end of the yacht 1 with the tail lift 2 near a quay wall 21. The hoist of the tail lift 2 is indicated only with the guide parallelogram.

FIG. 6 shows the gangway 16 in isometric view freestanding in the application. The staircase 7 with steps 8 and the staircase cylinder 20, which rests as a power drive 28 the stairs section in its position of use, sitting as a sliding unit on a sliding plate 23rd

In the lower region, the stairway section 7 is connected to the base 19 via the staircase axis 12 and via guide rails 14 on both sides. The stairwell 12 is guided in the guide rails 14 by means of a slot on a slot guide (slot-shaped receptacle 15). As a result, a longitudinal guide means 30 for the web and / or stairway section 7 is formed. The staircase spring 10 ensures that the staircase section 7 with its staircase 9 always in the direction of the quay wall 21 (FIG. FIG. 5 ) is pressed. The staircase spring 10 may be both a mechanical pressure or tension spring, but also as a gas pressure damper, pneumatic cylinder or hydraulic cylinder (with spring) to be executed.

The staircase cylinder 20 as a power drive 28 increases the ease of use when e.g. is designed as a gas spring. For larger gangways 16 pneumatic or hydraulic cylinders or other power drives can be selected, which position the web and / or stair section motor between working position and use position. In this case, the staircase spring 10 should also be designed as a motor power drive, in particular cylinder. This embodiment also offers the advantage that e.g. when leaving the yacht, the gangway does not need to be returned to its stowage position, but e.g. remote control of the stair section 7 is pivoted by the staircase cylinder 20 so far in the vertical direction that an unauthorized access to the yacht is prevented.

When the gangway locking bolts 18 ( FIGS. 2, 3 . 4 ), so a certain decoupling of the gangway of Querschaukelbewegungen the yacht can be achieved about its longitudinal axis. The prerequisite for this, however, is that the gangway axis of rotation 17 coincides exactly with the swing axis of the yacht 1, which is often the case in the harbor. This decoupling is supported by the above-mentioned floating support of the web and / or staircase section by staircase transverse springs 11 (FIG. Figures 2-4 ).

The gangway 16 or a walk-on bridge and / or stairway section 7 of the gangway can, as shown in horizontal distance to a quay wall 21 may be positioned, or it may float in the region of the edge or above the quay wall 21 or be placed on the quay wall with a particular angled and / or extendable end portion. The bridge or stairway section 7 can also be kept floating over Elastifizierungsmittel a few centimeters to decimeters above the quay wall, so that it touches the quay wall only when loaded, so when a user enters the gangway. Again, this is possible without limiting the basic inventive idea of the present patent application.
