Description

Security Tenderlift

Technical area

The invention relates to a Tenderlift for watercraft, which serves as a lifting platform people, but in particular as a lift, which safely accommodates dinghies and the like, parked and locked, according to a high safety standard, which also includes the lifting mechanism and the connecting stairs, according to the preamble of first claim.

State of the art

Height-adjustable support platforms are increasingly used for the reception of tender boats, as described, inter alia, in US Pat. No. 4,157,596, GB 2319014, DE 199 63 057 C1, or WO 03/106254 A1, but also for a comfortable boarding and boarding of bathers and divers. In addition, height-adjustable support platforms are also used for commercial purposes, such as rescue operations.

Presentation of the invention

The invention has for its object to attach to the stern of a watercraft, a height-adjustable platform that can be both a floating platform and a tender platform with a targeted recording of dinghies and the like, which places this space saving on the platform or in an adjacent room and seaworthy locked. Furthermore, the mechanism is designed so that the swivel arms safely avoid shearing and crushing. In order not to constantly operate the lift every time it is down, e.g. Quickly get or remove something from board is a simple, integrated and load-releasable connection stairs available, so you can always move quickly and easily from the vessel to the platform and vice versa.

The inclusion of a dinghy or jet skis, here called Tender for short, is not easy to accomplish with choppy water, since the yacht has a different roll and pounding frequency than the small tender. Therefore, means are provided so that the driver of the tender in a simple way the lifting platform and retract safely and automatically braked in the right place, the driver thus only has to give the command for lifting the lifting platform, while simultaneously, resp. With a time delay, the tender positions itself to be parked on top of the yacht deck or in the elevated lifting platform position to save space. In order to ensure a safe lifting of the tender, this is already brought into an appropriate grip, so that the tender can not slip from the lifting platform even in heavy waves. The positioning, the securing and finally the locking of the

Lifting platform with the tender runs without the assistance of third parties to provide further security in this regard, because persons on the lifting platform, who have to turn the Tender and tie down, are risky actions, especially on recreational yachts where often no professional crew on board.

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

The core of the invention is to install a lift as a floating platform and tender platform at the stern of a watercraft and a high safety standard points To ensure reliable and space-saving tender recording without the assistance of third parties, as well as a form-integrated safety mechanism to avoid shearing and crushing, as well as to integrate a smart, self-unfolding ladder between the stern of the vessel and the lift.

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 tender lift 1, which is secured to the rear 2 of a watercraft with the two pivot arms 3a, 3b, which form a parallelogram. It is known that in a parallelogram, the corresponding gap size of the two pivot arms 3a, 3b changes depending on the stroke position H1, H2 to each other in the course of the stroke H and thus can mean squeezing for third parties. Due to the structural overlap by means of a suitable profile and a precise position of the pivot arms 3a, b to each other, so that the gap 3c covered and thus the stability of the pivot arm 3a, 3b are increased simultaneously. Conceivable is a blending of the pivot arms 3a, 3b with plastic elements, but the constructive one-piece solution, namely the pivot arms 3a, 3b to protect against an open gap 3c, at the same time to increase the stability of the arms, is obviously an ideal combination. Also, the shapes on the carrier 4 are designed, e.g. by rounding 4a with large radii, but also by constructive inclusion and integration of the carrier 4 in the pivot arms 3a, 3b, so that even at these points pinching foreign objects, whether the limb, deadwood or anchor lines and the like, practically excludes. Furthermore, the lifting cylinder 5 is integrated as possible in the pivot arms 3a, b and where this is not feasible, this is wrapped separately by a sheath 5a, so that the lifting movement and pivoting of the lifting cylinder 5 also no blemishes in third or disturbances on the Can lead plant.

Fig. 2 shows a schematic front view of the Schwenkarmquerschnitte the

Pivot arms 3a, 3b, for example, only the pivot arm 3a has a U profile, while the pivot arm 3b shows a closed profile, wherein it is characteristic that the two pivot arms 3a, 3b diverge not more than the measure a in the stroke H, ie in that the construction of the tender lift 1 is designed in such a way that, in the worst case, the two pivoting arms 3a, 3b are flush with one another, in the worst case, they are normally guided nested one inside the other. By way of example, the shape of the sheet metal or of the plastic part also makes it possible to recognize the more rigid shape, which is technical Means 6 as torsion or bearings or lifting cylinder 5 can accommodate simplified.

FIG. 3 shows a schematic side view of sequences of movements when a tender 7 is received on the platform 8. The problem of getting a tender 7 on board safely and in reasonable time on light sea is not easy and usually requires a second or third party even third person to place the tender 7 correctly. After that, this must be lifted and lashed. Fig. 3a now shows how the tender 7 between the dipsticks 9a, b can be retracted, which not only help the tender 7 easily and simply help, but the two front dipsticks 9a are, according to the hull shape of the tender also slightly closer together, so that the Tender 7 can enter only to a predetermined point and is stopped there by the narrowing of the front dip sticks 9a. Furthermore, the dipsticks 9a, b have an upper support in the form of e.g. a bow means 9c, so that they prevent tipping out of the tender 7. Thus, the tender 7 is brought quickly and safely in position. Below the fuselage of the tender 7 are Aufkimmungselemente 10, which ensure that the tender 7 rests stable. By Tenderverriegelung 11, which is manually activated by means of pawl lock or motor, it is ensured that the tender 7 can not unintentionally slip out of the dipsticks 9a, b fencing backwards. The dipsticks 9a, b and the Aufkimmelemente 10 are mounted on a revolving stage 12 which with the detained thereon tender 7, by a corresponding means, e.g. let rotate by 90 °, so that the tender 7 is finally held transversely to the direction of travel of the yacht at the stern 2. The rotation of the tender on the revolving stage is carried out either synchronously with the lifting of the tender lift 1, either positively controlled or by means of active cylinder and control electronics, or independently of stroke H of the tender lift 1, also controlled by means of an appropriate electronics.

FIG. 3b shows the tender 7, which has been raised above the waterline WL and has already been rotated. The rotation is necessary because platforms 8 do not have the required depth which corresponds to the length of a tender 7. Yachts point against it enough width to accommodate neatly long Tenders 7, so these are usually moored across the yacht.

Fig. 3 shows the fully raised tender lift 1 and the transverse tender 7 which is anchored to the platform 8 by means of the raising elements 10, dip sticks 9a, b, bow means 9c, tender lock 11, without assistance

Third parties. In principle, the tender 7 can also retract laterally onto the platform 8, if the vessel does not have a design enclosure of the platform 8, but this is still less easy to do in waves, but with the dipsticks 9a, b, arc means 9c, uplift elements 10 and Tenderverriegelung 11 this form of Tenderaufnahme is also possible.

4 shows a three-dimensional view of the revolving platform 12, which is embedded in the platform 8, with the aiming bars 9a, b, the arc means 9c, the Aufkim- melementen 10 and the Tenderverriegelung 11. The Aufkimmelemente 10 and the attached dipsticks 9a, b and the tender lock 11 have hinges

13, which makes it possible to sink these parts in the openable middle segments 14 of the rotary stage 12, so that the platform 8 forms a surface with the revolving stage 12 and no disturbing parts rise when no tender 7 is on the platform. The platform can be rotated in both directions according to the arrow T.

5 shows a schematic side view of the platform 8 with the revolving stage 12, which by means of a pivot bearing 15 and a bracket 16 on the platform 8 easily rotatable, and is also mounted with low backlash. On one of the pivot arms 3a, b, a rod 17 is rotatably mounted, which is connected to a

Pin 18, which in turn is rotatably mounted on the revolving stage 12. For a simple but efficient forced control is made, because by the lifting movement H of the pivot arms 3a, b, resp. the platform 8, pushes the rod 17 in the direction of the arrow Z and thus performs a positively controlled rotation of the turntable 12 from. By a suitable distance of the pin 18 from the center of the

Platform 8, the rotation T can be designed so that at a corresponding depth of the tender 7 is watered and thereby the rotation T is exactly 90 ° or has any other desired value. 6 shows a schematic side view of the platform 8 with the turntable 12, which is mounted by means of a pivot bearing 15 and a bracket 16 on the platform 8 easily rotatable and low backlash mounted. On one of the pivot arms 3a, b, a working cylinder 19 is mounted instead of the rod 17, which due to the command output of the correspondingly programmed control unit 20, the

Turning platform 12 is activated and this turns according to arrow T. Thus, e.g. the tender 7 are first rotated 90 ° before the tender lift 1 rises, or any other configuration which benefits the tender 7 and the lifting operation.

Fig. 7 shows a schematic side view of the raised platform 8 with a rail means 21 positioned on the revolving platform 12 and having corresponding sliding elements 22, e.g. in the form of wheels or skids, which sits on a pair of rails 23. On the rail means 21 is the dipsticks 9a, b with the bow means 9c, the Aufkimmelementen 10 and the tender lock 11. The rail means 21 on the platform 8 can be driven in the raised position of the tender lift 1 according to arrow R toward the rear support 2a and the Tender 7 are led away from Tenderlift 1, so that it can be used as a pure bathing platform lift, or the tender 7 is moved into a garage within the vessel. The rail means after the displacement by means of the rail lock 24 securely in the desired

Position locked. The displacement of the rail 21 can be done manually or by motor.

Fig. 8 shows a schematic side view of an extendable and unlatchable connection conductor 25, which on the one hand rotatably mounted on the stern 2 of the vessel and on the other hand on the platform 8, rotatably mounted and longitudinally freely movable in a guide tube 26, attached. The connection conductor 25 comes so when booting the tender lift 1 under the platform 8 to lie as a telescopic ladder. Instead of a ladder, a staircase can also be used. Furthermore, the pivot bearing 27 of the connecting conductor 25 on Ausklinkelemente 28, so that in a compression or jamming of foreign objects on or in the connection conductor 25, this disengages and thus the Einklemmgegenstand, as well as the Tenderlift 1, preserved from damage. The Notching can be a clip or a motor-dependent hydraulic or pneumatic load-dependent opening element.

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