Description

Technical area

The invention is based on a segmented plate which serves as a stairlift, gangway and swimming platform and is preferably mounted on the stern of a watercraft, quasi self-supporting, but with safety support and inclination means in the form of a suitably placed working cylinder, the segmented plate elements and the adjustment mechanism having security means which are able to exclude shear and pinch points, according to the preamble of the first claim.

State of the art

In the marine sector, rigid floating platforms are known, to which mainly manual, mostly telescopic foldable ladders are attached, as described in the patent EP 1 616 782 A1 , in ships extendable stairs are used, the hydraulic and also by winch, as described in the patent MXPA 02011583 Doing their work, in recreational motor yachts are by means of cylinders, hydraulic or electric, extendable ladders, as well as stairs with horizontally remaining treads in use. These serve the passengers and the four-legged animals mostly as a comfortable departure or ascent into or out of the water. For large ships, the stairs are also used for shore leave.

The motor-operated ladders and stairs are stored directly in the watercraft or in the floating platforms in cassettes and are extended from these horizontally full extent, and then tilted over an articulation in the water direction, as described in the patent FR 2878822 , In many cases, the inclination is carried out by means of another effective cylinder. A combination of rigid floating platform and movable stair elements is known under the US Pat. No. 2006/0075952 A1 which is tiltable without security elements with respect to shear and crush points on the stair elements.

Also known are lowerable swimming platforms, which are lowered to below the waterline, especially for the reception of dinghies and jet skis, as described, inter alia, in the patent DE 199 63 057 C1 ,

Presentation of the invention

The US 4,168,764 describes a staircase with according to the preamble of claim 1.

The US 2007/0101516 describes a device which can be used by moving stair elements as a ramp or as a staircase. The invention has for its object at the stern of a watercraft, overhanging to install a segmented plate, which performs the function of a floating platform, a lowerable stairs and a rampart gangway, the segmented plate elements, as well as the entire mechanics, against the pinching of limbs or other objects are protected and secured accordingly. Furthermore, the floating platform can be additionally lowered with such a staircase function as a whole, as well as being used via optional means as a lifting sled for light inflatable boats and the like.

The staircase function also makes it possible to raise the incline so that, like a gangway, it allows a raised pier or dock to be accessed on board without any ado, and, in addition, one or more panel elements can optionally be extended.

More and more boats and yachts are equipped at the rear with swimming platforms or stairs, on the one hand to be closer to the water by means of the floating platform, or easier to attach the Wasserskimittel to the feet, on the other hand to have a stair gear to the water back aboard the boat or the To get to the yacht. Many swimming platforms have pull-out stairs so you can get in or out of the water better. Lowerable swimming platforms are a great luxury but extremely comfortable and are usually purchased in conjunction with the lift function for a dinghy.

The invention brings the advantages of a floating platform with the advantages of large, otherwise only to find yachts extendable and inclinable stairs with the constant remaining horizontal stairs, in an elegant, space-saving and simple way together, with a special attention to the safety of people and at the same time also dedicated to mechanics. Thus, all functions and uses of a swimming platform are maintained, the comfortable horizontal staircases are easily accessible and have a high safety standard and are also accessible, even if the staircase is in motion.

Since steps under water are difficult to see, the moving parts of the mechanics are protected against shear and crushing risks, the steps can be unlatched or unilaterally deformed under appropriate load and direction and can be equipped with a detection sensor and stub electronics, so that when entering the stairs possibly limbs or other foreign bodies, which in the staircase mechanics or get caught between the stairs and the swimming platform, do not suffer any damage, but also the mechanics will not be damaged.

Furthermore, the individual plate elements are locked in the parking position in the floating platform position, to avoid loosening or rattling of the treads by swell or other influences.

The floating platform with the step function can also have rail elements, so that a tender, e.g. taken by a karts and can be driven after elevation, manually or by motor, in the direction of the rear wall or directly into a garage.

Also, the floating platform with the staircase function is not only one-sided on the lowering of the elements aligned, but this can also be moved to a lifting position, so that it can be used as a gangway, especially in conjunction with the extendable additional plate elements and the suspension, resp. Damping function of the lifting mechanism in the event of a jib or dock impact.

To convert the lifting movement around the floating platform into a lowerable staircase or gangway is by means of either an active active cylinder, e.g. hydraulic, pneumatic, electric action cylinder, or by means of a passive working cylinder, which represents a gas spring.

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

The core of the invention is to install at the stern of a watercraft, a floating platform with a high safety standard stair function, which can be lowered or raised, by means of an active or passive active cylinder equipped with gap-covering means, releasable or unilaterally deformable stages, one or more contact sensors with stop release and additional security and locking devices.

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

Way to carry out the invention

Fig. 1

shows a schematic side view of a projecting beyond the tail 1 of a watercraft segmented plate 2, consisting of a plurality of segment strips 5 and their security means 51, which is supported by a Variomittel 3 and by means of the action cylinder 4 lowering or lifting the Variomittels 3 allows. The segmented plate 2 serves as a floating platform in the horizontal inclination position A, or as a stairway to the water, or under the waterline WL, or the incline positions C upwards as a gangway, to make the pier or the landing stage more favorable to reach.
The segmented plate 2 consists of segment strips 5, which lined up form a flat plate, wherein the segment strips 5 are rotatably supported by means of axes of rotation 6 and the attached cam 7 in a clip holder 8, which is located on the variometer 3, are taken. By the lifting movement H of the variometer 3, the segment strips 5 remain horizontal, since the variometer 3 forms a parallelogram in this example, by means of the tilt arms 9a, 9b, which are mounted rotatably mounted on the console 10 and the console 10 is mounted on the rear 1. The horizontal attitude of the segment strips 5 on the variometer 3 can also be accomplished by other means, such as by means of a stepping motor, in which the angle of inclination of the variometer 3 is measured and accordingly the segment strips 5 are readjusted. Also, the segment strips 5 can be held in the desired position via a positively controlled gear drive or belt drive, it is common to all that the segment strips 5 with appropriate load such as a Hinge rate of a foreign part in the mechanics, causes the segment strips 5 is made of the Release the swivel anchor and the lifting movement H is stopped immediately. Of course, the segment strips 5 can also have other security elements. The protectable mechanism relates on the one hand to the movable segment strips 5, on the other hand on the two tilt arms 9a, 9b, which change the distances of the tilt arms 9a, 9b to each other during the lifting movement over the stroke H, and these are therefore completely covered by a cover 11 ,
The active cylinder 4 supports the plate 2 so that it remains solid even in strong swell in the normal tilt position A in position, even if an object is fixed to it or in the staircase function to the mechanics in the swell by means of the appropriate support the Wirkzylinder 4, to keep stiff. The active cylinder 4 can either be supported directly on the rear 1 or on the correspondingly shaped bracket 10. To prevent unwanted dropping of the active cylinder 4, a lifting lock 50 is provided, which in a hydraulically operated active cylinder 4, for example, a check valve in an electric working cylinder 4 is a self-locking spindle and may include a gas blocking element in a gas spring or provides an additional mechanical lock, such as a mechanical lock between plate 2 and rear 1. Together these locking solutions, another security means 51 with respect to the tiltable and segmented plate 2 is available put. The safety means 51, in addition to the notching function, comprise the deformable elements described below, electronic means and others, wherein not all of them must simultaneously be used in the corresponding, differently shaped segment strips 5. On Variomittel 3 is also a fold-out railing 12, so bathers can enjoy the comfortable staircase as well as the gangway function in addition, which also serves safety, especially in rough seas.

Fig. 2

shows a schematic side view of the segmented plate 2 with the individual ausklinkbaren segment strips 5. The segment strips 5 are rotatably mounted by means of the axis of rotation 6 and 9A attached to the tilt arm, could be clipped and are hooked by the cam 7 in the clip holder 8, the clip holder 8 am Tilt arm 9b is moored. This simple geometry in connection with a parallelogram as shown here as Variomittel 3, keeps the segment strips 5 thus always horizontal. The clip holder 8 is advantageously made of plastic with a suitable spring detection and has a sensor 13 which is connected to the electronics 14. This is at contact loss on the sensor 13 a stop command to the active cylinder 4 on. This function is central, should a limb, foot or hand or other foreign element 15 are located between one of the segmental strips 5, exactly while the variomittel 3 moves upward, because then the distance from Segmentleiste 5 to Segmentleiste 5 is getting smaller and a massive clamps or worse would be the consequences. Due to the increasing pressure on the corresponding segment strips 5, the cam 7 jumps out of the clip holder 8 and gives the foreign element 15 space, at the same time, due to the loss of contact on the sensor 13, the lifting movement H is stopped immediately by means of the electronics 14. By means of the spring 28, shown here only at one point, this brings the segment strip 5 back to the starting position once the problem with the foreign element 15 is resolved.
Another backup is the contact strip 16. In the case of excessive pressure on this contact strip 16 is applied, the active cylinder 4 is also stopped immediately by means of the electronics 14. As with slightly moving water, the contours are not exactly visible just below the water surface WL, a visual aid can be attached, so that by a light bar 17, the person visually recognizes where the limit for the feet or hands. An optical strip also has the advantage of delivering an interesting additional lighting at the rear 1 at night.
In addition, on one of the segment strips 5, usually in the last segment strip 5, an extension part 18, which allows a water ski thanks to more contact surface, ie, comfortable and safe to install, only to be discontinued into the water. Also come on board is a first, larger focal point in the form of an extension part 18 together with the segment strips 5, more pleasant and secure to obtain.
Such extension parts 18 can also be attached elsewhere, so that in the step function, the bathers can sit down on such enlarged areas to sit even closer to the water or partially in the water. Cup holders and other mounts allow you to enjoy the position you have taken longer and longer.

Figure 3

shows a schematic side view of an unclaimed segmented plate 2 with the individual segment strips 5, which have deformable elements 19. Wedged when booting the Variomittels 3 with its cover 11 on the hub H unfortunately a foreign body 15 between the segment strips 5, the stroke H is stopped by means of signaling through the sensor 13 to the electronics 14, the active cylinder 4 immediately.
If a foreign object 15 has reached the segmental strips 5 for a long period of time, and if the segmented plate 2 is now tended to tilt downwards by means of the variometer 3, then the process remains inactive, since eg driftwood has become wedged and lowering the segment strips 5 would lead to damage to the mechanism. A bypass switch 22 allows the Wrkzylinder 4 despite contact loss on the sensor 13, activate in personal responsibility.

3a

shows a schematic side view of an unclaimed deformable element 19. This has an overhead, elastic and walk-surface 20, including rigid segments 21 are mounted, one is glued or connected to the other, each segment 21 has only a direct contact with the Surface 20, for each segment 21 is supported on the other segment 21 and thus a bending or buckling of the elastic surface 20 is prevented. The deformable element 19 has a sensor 13 which is e.g. a strain gauge, an optical encoder or button can be so that upon deformation of the surface 20, the sensor 13, the signal to the electronics 14 passes and then the active cylinder 4 is stopped immediately.

Figure 4

shows a schematic side view of ausklinkbaren segment strips 5 in particular for the upward inclination, ie in the tilt position C, which has an additional releasable clip holder 8a. The tilt arms 9a, 9b attached to the bracket 10 by means of the pivot bearings 9c, 9d generate a parallelogram and, because of this parallelogram geometry, while the variometer 3 descends downwardly, the segment strips 5 are constantly closer and finally in the tilt position A lying next to each other. Therefore, the segment strips 5 are unlatched from the opposite side, ie, in the case of a foreign body 15 is located between the segment strips 5 during the stroke H, both clip holders 8 and 8a are active, the segment strip 5 is cliped and the sensor 13 indicates the loss of contact the electronics 14 and thus triggers the command to stop the stroke H immediately. This preserves the high safety standard.
Figure 5 shows a schematic side view of an unclaimed segmented plate 2 with arcuate segment strips 5, for example in three lifting positions C, A, B. For yachts with enough space under a horizontally held plate 2, therefore, ideally fully wrapped segment strips 5 can be used, so that a foreign element 15, such as a foot, can never fall below or between the segment strips 5, whether the Variomittel 3 upwards in the tilt position C or inclined downwards in tilt position B. In the tilt position A, the segment strips 5 are normally accessible and thus one or the other security means are omitted, the cover 11, in the case of using a parallelogram with the tilting arms 9a, 9b, remains.

5a

shows a schematic side view of the unclaimed segmented plate 2 with variable conical segment strips 5, for example in a stepped position. Due to the arcuate stroke H of the variometer 3, the distance from the segment strip 5 to the next segment strip 5 changes depending on the inclination position. So that the segment strips 5 remain gap-free with respect to each other, the segment strips 5 each have a hinge 23 on the two side edges of the surface 20a, which hold the side covers 24. Below the surface 20a there are compression springs 25, which are supported against the rib 26. This ensures that the side cover 24 of a segment strip 5 always rests firmly against the opposite segment strip 5 on the side cover 24.

Fig. 6

shows a schematic side view of the segmented plate 2 in the tilt position C, which can be ideally used with the unfolded extension part 18, as a gangway by the last segment bar 5 can be adapted to a web 27 at low tide or high tide. Should by carelessness or swell the Variomittel 3 with its segment strip 5 strike on the web 27, so the system takes no damage, since the segment strip 5, by means of the rotation axis 6, cam 7 and clip holder 8 disengages. As soon as the problem no longer exists, the extension part 18, resp. the segment strip 5 back to the starting position, by means of the spring action of the spring 28th
If the notching is reported by the sensor 13 to the electronics 14, then the effective cylinder 4 extends by a stroke value x until no notching of the segment strip 5 is reported more. It is conceivable to equip the whole with a proximity switch and also forward the signal to the electronics 14, which activates the active cylinder 4 accordingly. If the segment strip 5, resp. the extension member 18 taken from the front, according to arrow K, a positive pressure valve 29 acts on the hydraulic unit 30 and makes the hydraulic fluid from the active cylinder 4 soft, in an electric drive, this would be a freewheeling element, so that the cylinder does not remain adamant and takes damage or the entire Plant suffers. The pressure relief valve reports to the electronics 14 the actual state and thus the command triggers the effective cylinder 4 to drive away to avoid damage.
This configuration is also suitable for a staircase mode. If the plate in the tilt position B and the Z-drive, not shown here, is pivoted up, so this would be against the torque tube 49 described further back, and thus activate the pressure relief valve 29 immediately. A Wamton 53 would also point to the upcoming problem. In addition, attached to most Z-drives trim indicator 52, which is usually a Drehpoti, used to report the actual signal to the electronics 14, so that the Z-drive can not be swung in such a case, or at a already raised Z-drive, the Treppenfunktiori is blocked.

Fig. 7

shows a schematic side view of the segmented plate 2 with individually ausklinkbaren segment strips 5 with a locking mechanism 31, consisting of a trigger 32 which pushes a locking bar 33 in the locking receivers 34. This function is advisable as soon as the plate 2 remains in the tilting position A, so that waves can not disengage the segmental strips 5 or when driving due to the impacts on the hull of the vessel, the segment strips 5 do not rattle. As long as the locking mechanism 31 is active, the effective cylinder 4 can not be activated.

Fig. 8

shows a schematic side view of the segmented plate 2 with the individual releasable segment strips 5 with a passive locking mechanism 31 a, consisting of a spring-loaded ball 47 and the ball seat 48, which represents a recess in the tilt arm 9b. The passive locking mechanism 31 a is just at the horizontal inclination position A, the segment strips 5 hold to a rattle or not always have the risk that the segment strips disengage 5 at a wave. The spring-loaded balls 47 in the segment strips 5 are therefore pressed into the recesses 9b of the ball socket 48 and hold them in the tilting arm 9b until they reach an adjustable pressure. If the action cylinder 4 moves in or out, the variometer 3 is correspondingly inclined and thus the spring-loaded ball 47 leaves the ball seat 48 and thus the segment bar 5 can be unlatched again normally.

Fig. 9

shows a schematic plan view of a segmented plate 2 with recessed on the segment strips 5 rail elements 35. A Tenderwagen 36 with receiving means 37 can be set to the rail elements 35 waveproof and, in the case of the Variomittel 3, the segment strips 5 has moved down a dinghy be placed on the tender car 36. Thereafter, the zooming means 3 is raised to the tilt position A, so that the rail elements 35 extend horizontally and the tender car 36 toward the rear 1, manually or motor according to arrow Z, can be driven. For this displacement operation are therefore under the tender carriage 36 sliding members 38, which may be rollers or slides. By means of the tender car lock 39, the tender car 36 can be firmly locked in the suitable parking position.

Fig. 10

shows a schematic side view of the segmented plate 2, which is under a height-adjustable swimming platform 40 extendable and tiltable. The floating platform plate 41 may be a standard platform or a plate 2 with the corresponding segment strips 5. The plate 2, together with the otherwise attached to the rear 2 console 10 and at this point ideally additionally attached active cylinder 4, by means of a track 43 to the end of the swimming platform 40 and thereby significantly increase the walk-in area, as well as the additional inclination positions B and C use.

Fig. 11

shows a schematic side view of the segmented plate 2 with the individual releasable segment strips 5 and the extension part 18. The activation of the Variomittels 3 takes place by means of the active cylinder 4 via a blockable, pressure-designed gas spring 44, which by means of a Bowden cable 42 or by means of a hydraulic Entsperrers 45 can be moved and locked in any position and released again. The change in inclination of the Variomittels 3 by means of weight load according to arrow G, resp. Weight removal from the plate 2, since the gas spring 44 selected here by way of example is always designed to extend in the direction. If a person wants to use the staircase function and drive, for example, into the inclination position B, she uses her own body weight and actuates the unlocker 45 or the Bowden cable 42, so that the gas spring 44 can be compressed and the variometer 3 thereby tilts downwards. If the Variomittel 3 are raised, the person leaves the segment strips 5 and presses the Entsperrer 45 or the Bowden cable 42 and the Variomittel 3 moves up. If the plate 2 are also used as a gangway, the gangway barrier 46 is released and thus the Variomittel 3 can start up and reach, for example, the tilt position C. By releasing the Entsperrers 45, resp. of the Bowden cable 42, the gas spring 44 is locked in any desired tilt position and can now by the person as Gangway be used. To return the gangway position back to a horizontal inclination position A, again the weight of a person has the function of compressing the gas strut 44, wherein in the horizontal position, a clinker blocking function automatically activates the aisle barrier 46 so that, without a clear intention, the variome 3 does not move higher can be as in the horizontal position, ie in the tilt position A. This is at the same time the standard position and the appearance and function of a normal swimming platform similar. Thus, the gas spring 44 also has a normal support function of the plate 2. Since the start-up of the Variomittels 3 works only by weight relief, may be omitted for reasons of cost on the Ausklinkfunktion the segment strips 5.
In the case of two gas spring 44 are mounted on Variomittel 3 and because gas spring generally not necessarily always exactly the same Ausschubgeschwindigkeit - applies to the Wirkzylinder 4 - or compression effect and also the weight distribution on the plate 2 is rarely symmetrical, a torsion 49 between the Inclined arms 9b mounted to the two tilt arms 9b connected as stiff as possible with each other, so that the best possible harmonization of the tilting process of the Variomittels 3 takes place.

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