Abstract

The invention relates to a tender mount (1), which comprises correspondingly shaped retaining means (4) rotatably supported on a deadrise retainer (2), which retaining means are preloaded manually or by means of operating cylinders (5) and springs (6) such that the retaining means press against the tender (22) in a slip-proof manner using docking means (29), wherein the exact position is optionally determined in advance by means of sensors (30), and thus appropriate functions are triggered by means of the controller (19). If lowerable stairs (8) or a platform (80) or a support surface (51) is mounted to the rear (20) of the water vehicle, the tender (22) is swiveled out by means of the swivel arms (7) or driven out by means of a sled (81) during lowering. The weight of the platform (80) or the stairs (8) and of the tender mount (1) can be compensated by means of the static buoyancy force of the buoyant element (14). A gas pressure damper (37) can be used for support in order to raise the platform (80) or stairs (8) safely.

Description

tender recording

Technical area

The invention is based on a recording and attachment of a tender on a platform at the stern of a watercraft, so that the positioning and fixing on the platform quickly and safely done by simple technical means and is designed so that the watering or catching a tender also automatically and controlled, according to the preamble of the first claim.

State of the art

Height-adjustable support means are increasingly used for receiving and securing tender boats, as described, inter alia, in US Pat. No. 6,095,080, US Pat. No. 4,157,596, GB 2319014, DE 19963 057 C1, or WO1996GB01177 19960517, which deals with various lifting techniques and recording devices for the tenders. The clean positioning on the underlying platform as well as the mooring of a tender is still the work of the ship's crew.

Presentation of the invention

The invention has for its object to quickly and easily position a tender, which may also be a jet ski or a similar vehicle on a platform or a lowerable staircase which extends at the rear of a watercraft and secure at the desired location, using manual or electronic means to easily release the tender and release it easily.

The recording of a tender is not easy to solve even with slightly choppy water or some wind, since the yacht has a different roll and stamping frequency than a small tender, resp. Both vehicles have a different strong drift. Therefore, means are provided so that the driver of the tender can easily locate the lifting platform or the swinging arms in a stair configuration and safely retract there and thereby automatically stopped in the right place. The driver thus has only to press the lock, which can also be done by means of a remote control or automatically and mitauslöst the command for lifting the lifting platform, the tender was due to appropriate means in advance automatically placed in position and secured. The underlying platform or

swinging arm configuration can then safely resp. be retracted. The tender can be longitudinally or transversely mounted at the stern or on the deck or in the garage of the vessel and parked by these means. The

Positioning, posture and finally locking the tender on the lift will be done without the assistance of third parties and will be a further safety, as people on the lift platform who have to turn and tie down the tender and where it is usually wet, are taking a risk action especially on recreational yachts where often no professional crew is on board.

According to the invention this is achieved by the features of the first claim. The essence of the invention is to install an easily feasible, fast and accurate Tenderaufnahme with a simple attachment of a tender without ropes and straps on a lift or stairs and this without the involvement of third parties.

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

In the following, embodiments of the invention will be explained in more detail with reference to the drawings. The same elements are provided in the various figures with the same reference numerals.

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

1 shows a schematic side view of a tender receptacle 1, consisting of a Aufkimmhalterung 2, on which on a rotating mechanism 3 a hinged

Holding means 4 is fixed, wherein a working cylinder 5 with a spring 6 triggers a folding movement. The Aufkimmhalterung 2 is mounted on a horizontal pivoting arm 7 which at an example. lowered stairs 8 is attached. The pivot arm 7 has an upper pivot bearing 9a and a lower pivot bearing 9b and the pivot arm 7 is mounted by means of the mounted in the staircase 8 axis of rotation

10 at which a gear pair 11 or linkage or V-belt is operated by a pivot motor 12. Under the staircase 8 is located on each side of the rear 20 attached to the Auftriebskörperlagem 13 buoyancy body 14, which are connected by means of telescopic connecting means 15 with the staircase 8. Under the stairs 8 or between the buoyancy bodies 14 is a

Wing 16 attached. The staircase 8 can be pivoted by means of a pivot bearing set 17 via the stroke H below the waterline WL, by means not shown lowering and lowering lever, wherein the pivot bearing set 17, a lowering sensor 18 is mounted to detect the Absenkwinkels and the lowering sensor 18 is connected to the controller 19 ,

The staircase 8 is advantageously mounted on the rear 20 and may also represent a platform 80 with the corresponding Absenkhebel and active agent. The

Pivot arms 7 have pads 21, such as e.g. Roll, so the

Swivel arms are not constantly, especially in the swell, floating the weight of Tender 22 need to hold. On a pivot arm 7 or at another suitable location is a position sensor 23, which informs about in which position the pivot arms 7 are located. In the position shown here, the position sensor 23 informs the controller 19 that the staircase 8 may not be moved downwards in the direction of the arrow H. Only from a certain Ausschwenkwinkelwert according to arrow W, the staircase 8 may be driven down, because under this provision, the tender is 22 resp. the pivot arm 7 according to arrow A accordingly extended to the rear and thus can not collide with the staircase 8. Before the pivot arms 7 are deflected, it is possible to start up the stairs 8 by a lifting set HS, so that the staircase 8 faces upwards and the support 21 which at the same time can also constitute a rotation lock, so that the step 8a no longer touches and therefore freely pivotable is.

If the tender 22 in the water and this should be obtained, so first the pivot arms 7 are extended in the direction of arrow A, then the stairs 8 moves down below the waterline WL. The staircase 8 has stairs 8a, which thus remain horizontal by the parallel pivot arms, not shown here, so that the pivot lever 7 also remain horizontal. The stair steps 8a are open so that water can flow into the interior of each stair step 8a, except in the area of the rotation axis 10, gear pair 11 and swing motor 12. This prevents the stairs 8a from becoming a buoyant body and lifting the stern 20 of the watercraft becomes. When lowering the stairs 8, it is even desirable that the watercraft in the

Rear section gains some depth, so the stairs 8 has to be lowered less. In order to keep the steps 8a always horizontal as possible, by means of a step compensator 24, consisting of a plate 25, which can be pivoted by means of a Trimmwirkzylinders 26 to the trim joint 27 or Trimmwirkzylinder 26 directly, e.g. so that a single pivot of the

Drehlagersatzes 17 can be moved horizontally, in this way the stairs in the Lot, resp. hold the pivot arms 7 in the horizontal position as possible. This makes it possible, even in rough seas, e.g. a largely stable horizontal position of the staircase 8, by means of the inclusion of the controller 19, a tilt sensor and a scheme for the lifting of Trimmwirkzylinders 26 to ensure.

The buoyancy bodies 14 have the function of compensating the outboard weight of the staircase 8, the tender receiver 1 and possibly parts of the tender 22, so that the vessel remains well trimmed even with this additional weight outside of the fuselage. Furthermore, the buoyancy bodies 14 are tilted by means of the buoyant body bearings 13, for example, at the angle of the launch of the watercraft. Thus, when lowering the stairs 8 due to the connecting means 15 between the staircase 8 and buoyancy body 14, the buoyant body 14 is pivoted outwards and leads to an additional stabilization of the water vehicle. Depending on the mood, the total width of a widened

Watercraft in the rear easily by 15%. Of course, the buoyancy bodies 14 also produce a dynamic buoyancy, without annoying traveling resistance due to the attached under the buoyancy body 14 stages 14a, as a stall. In very stern-heavy vessels or at

Catamarans may be mounted behind the vessel's hull, but not under the vehicle's hull, on the platform 80 or stairway 8, a corresponding wing 16 which provides additional dynamic buoyancy and may be rigid or movable to inflate. Also, such a wing 16 are also attached to the buoyancy bodies 14 wherein the

Attention kinking attention must be paid, due to the lowering of the platform 80 or stairs 8 laterally extending buoyancy bodies 14. Such a wing 16 is useful especially in the starting phase or can reduce the pitch of the vehicle bug during gliding.

If the tender 22 now travels between the retaining means 4 of the lowered staircase 8, the pole rods 28 help to orient the entrance. These can also be folded away if necessary or can be sunk accordingly. The tender 22 also has on the fuselage outer side docking means 29, which ultimately serve to lock the tender 22 together with the holding means 4. The bow-side holding means 4 are either set so that the tender 22 is keilmässig stopped with respect to the continuation in the bow or the docking means 29 are in the rear area so bulging that they are stopped by the rear-side holding means 4. Inductive sensors 30 on the underside of the tender 22 or in the support arms 4 allow the sensors to send positive signals due to the correct position of the tender 22 to the support means 4, the staircase 8 being raised and the tender 22 thus raised on the pickup support 2 is seated. Thereafter, the support arms 4 close so that the tender 22 can not be lifted by the waves of the Aufkimmhalterung 2 and possibly slip, the stairs 8 is raised at the same time and the pivot arms 7 synchronously and monitored by the position sensor 23 screwed accordingly be that they do not collide with the stairs 8a. The active cylinder 5 are lockable or self-locking and have a spring 6, so that the holding means 4 always press with a bias against the tender 22. This is particularly recommended for tenders with an inflatable tube, as they breathe due to the daily temperature fluctuations: on a warm day, the shell stretches, in the cold night it contracts.

The spring 6 compensated so ideally the cross section of the hose. The rotating mechanism 3 may be e.g. Be designed over a rocker so that thus the top of Tenderschlauches is additionally pressurized by the curved holding means 4. The active cylinder 5 can also be mounted radially directly on the rotary mechanism 3 and a torsion spring element a

Preload.

The controller 19 may ensure further operations, such as that when the transmission or engine is running, the staircase 8 can not be lowered but in the high direction the lift activation is always possible. Furthermore, the tender 22 can only be swung out when the staircase 8 is at the top, resp. no collision between the swing arm 7 and 8a step is possible, or that the stairs 8 can be lowered only conditionally in case the holding means 4 are closed, otherwise there is a risk that the tender is locked on diving station or that by means of remote monitoring of the engine Tenders, at a signaled by the lowering sensor 18 corresponding angular position of the stairs, is turned off, so that the engine of the tender 22 does not run without cooling water intake and thus overheat.

Of course, the operations can also be performed manually, with the hand-held button not shown and described here, but manual entry is not very practical when swell. Instead of inductive sensors 30 photoelectric sensors, pressure sensors and other tools for position detection can be consulted.

In addition, at least one pivot arm 7 has an additional lock 31, which can also be integrated directly in the support 21, so that when driving the

Watercraft, the pivot arms 7 are optimally locked.

FIG. 2 shows a schematic top view of a tender receptacle 1 with the four foldable holding means 4 and the docking means 29a attached to the tender 22, FIG. 29b, which rear side the holding means 4 fully include and bugseitig eg no docking means 29 need to be attached, the front holding means 4 the tender 22 thus only stop and center and rear of the tender 22 by means of the docking means 29a, 29b slipping away from a backwards lock. Or it is located on the rear side only the docking means 29a and the docking means

29c at the bow of the tender 22, so that in this way the tender 22 can be held. As indicated, the retaining means 4 may be straight or curved. The curved holding means 4 firmly hold the tender 22 on the pickup bracket 2. By means of the controller 19, the opening and closing times as well as the opening angle or opening steps of the holding means 4 can be set so that the tender is e.g. is held behind, while the front is fully opened and by the subsequent opening of the rear support means 4, the tender 22 can extend elegant front, or when retracting the tender 22, the front holding means 4 are already closed, while the rear support means allow free access. Sensors 30 at the bottom of the tender 22 resp. At the appropriate locations on the tender receptacle 1, the controller 19 indicates that the tender 22 is in the proper position and the holding means 4 can be closed. It is conceivable that such sensors 30, even photoelectric sensors, are embedded in the holding means 4 and on the trunk surface of the tender 22 complementary sensors 30a are mounted, such. passive reflectors, or

Metal elements so that due to the correct position of the tender 22 relative to the holding means 4, a corresponding signal is output to the corresponding sensor 30 and thus the holding means 4 are closed. The Tenderaufnahme 1 can be firmly connected to the lowerable platform 80, or attached to the pivot arm 7 or on a releasable from the platform 80 support surface 51 or on a slide, not shown here

Rail holding means 53 which are located on the platform 80 or wing 51 or the individual steps of the staircase 8 and thus by lowering or and an extension of Tenderaufnahme 1, the tender 22 can be watered or brought back on board.

FIG. 3 shows a schematic top view of a tender receptacle 1 with the

horizontal pivoting arms 7, which are mounted on the stairs 8. The swivel Arms 7 are moved by the swing motor 12, for example via the V-belt 32 before lowering the staircase 8 in the direction of arrow W. The V-belt 32 synchronizes the two pivot arms 7 and engages the teeth 11 a, which is connected to the Schwenkarmgehäusen 7 a and the axis of rotation 10. In each Schwenkarmgehäuse 7a is a rotatably mounted toothed belt pulley 33, which on the one hand receives the pivoting V-belt 34 and on the other hand, the Aufkimmhalterung 2, which is only partially shown here. In one of the steps 8a, advantageously in the last, also the rigid pulley 35 is fixed, which has a bore in which the axis of rotation 10 is inserted and thus upon pivoting of the pivot arm 7, the pivoting V-belt 34 rotates about the rigid pulley 35 and thus the Aufkimmhalterung 2 maintains its orientation.

In addition, still a connecting rod 36 can be mounted between the two pivot arms 7, so as to give a further stability of the system. Of course, instead of the V-belt 32 or Schwenkkeilriemens 34, the function via linkages or additional gears, as well as with each other communicating swing motors 12 and the like.

In a simple lowerable platform 80, the pivot arms 7 are no advantage if enough space is available and there the Aufkimmhalterungen 2 are thus mounted directly on the corresponding platform 80.

4 shows a schematic side view of a tender receptacle 1, consisting

at least from a Aufkimmhalterung 2 with swivel arm 7, which are attached to the stairs 8 and including a buoyancy body 14 is located. It is evident that the Tenderaufnahme 1 each left and right each Aufkimmhalterung 2 with swivel arm 7 and also left and right under the staircase 8 are each a buoyancy body 14. The buoyancy bodies 14 advantageously have a height which reaches at most as far as the waterline WL, so that no additional buoyancy is generated when the staircase 8 is lowered. The static buoyancy should be chosen so that it compensates for the extra weight of a staircase 8 and Tenderaufnahme 1 with its buoyancy. This can ensure that the staircase 8 and the Tenderaufnahme 1 in case of failure of the Hebewirkzylinders not shown here according to the Archimedean principle upwards is pressed and the staircase 8 can be locked with means in the upper position. Nevertheless, it may be that the volume is not enough to drive up the whole system, so gas springs 37 are provided, which take over this lifting task. In the normal case, that means that the lifting cylinders have to press the stairs 8 with its tender receptacle 1 in the direction of the waterline WL and gravity does not take over the reduction. shows a schematic side view of a Tenderaufnahme 1 with hinged holding means 4, which are moved by the effective cylinders 5 via the rotary mechanisms 3 and cling to the mounted on the rigid body 22b strips 38. The strips 38 are shaped so that they position the tender 22 with the holding means 4 in the axis S and at the same time hold it down with a force, so that the tender 22 can not be lifted out of the tender receptacle 1 in the swell. The strips 38 can also generate depending on the design an additional dynamic buoyancy while driving or and thus an additional driving stability. The primary positioning of the tender 22 on the platform 80 is by means of fixed or removable guide rods 39 or bracket 40. It requires a transverse to the direction of travel of the vessel mounted bracket 40 and a front guide rod 39 or two

Guide rods 39 vome and at least one guide rod 39 in the back to bring the tender in the correct position. The two front

Guide rods 39 or the guide rod 39 and bracket 40 are so each other that the tender 22 can not pass through and this so that in the entrance by means of the corresponding selected terminal point, already positioned crosswise. If the tender 22 is now pressed against the bracket 40 or against at least one existing guide rod 39, the tender lies quite correctly in the axis S. By closing the retaining means 4, the tender is exactly centrically positioned, clamped and locked. If the ends of the holding means 4 are non-slip, this socket does not require docking means 29, which otherwise could even be applied directly to the strips 38.

It is also conceivable that the tender 22 by means of rear stop means 43 is held slipping and locked on the tender receiver 1. These pivotable stop means 43 may also have the same components as in the embodiment described above, to securely hold the tender 22.

The Tenderaufnahme 1 can be plugged into the platform 80 and moored and released accordingly and stowed when not in use, wherein the

Platform 80, the corresponding lines 41 are laid, equipped at their ends with waterproof, screw-in connectors 42, so that the embedded in the Aufkimmhalterung 2 Wirkzylinder 5, and possible sensors 30 are decoupled in an instant.

6 shows a schematic side view of a tender receptacle 1 with a

rotatably mounted, forward pivoting manual holding means 44, which is mechanically operated accordingly. By means of an unlocking means 45, the manual holding means 44 can be pivoted, which by means of a

Connecting means 46 and a cross-connecting means 46a is connected to a further manual holding means 44, so that by means of the confirmation of a manual holding means 44, the opposite and the front, possibly even curved, manual holding means 44 is actuated simultaneously according to arrow A - B, Α '- B '.

A rotary head 47 with a cam 48 is mounted on the manual holding means 44, so that when the manual holding means 44 is pivoted, the rotating head 47 rotates about the vertical axis of the manual holding means 44 by means of an angular gearwheel or a crownwheel embodiment located therein. according to arrow D and against a attached to the tender 22 docking means 29d presses, which serves that the tender 22 not backwards, ie against the arrow E, from the manual holding means 44 can slip out. In addition, above the cam 48 there is still material of the docking means 29d, so that the tender 22 can not move upwards either.

The manual holding means 44 can be connected by means of a further connecting means 46 with a mechanical stop means 49 mounted behind the tender 22, should the tender 22 have no docking means 29d and fix the tender 22 on the tender receiver 1 in this way.

The manual holding means 44 can be attached to the Aufkimmhalterung 2 or on the platform 80 or a carriage 81 by means of pivot bearing means 50. The carriage 81 is used to move the tender 22 on the staircase 8 or platform 80, eg for garage applications or continuing

Displacement applications and may be formed as a support surface 51 to accommodate the Aufkimmhalterung 2 and, if necessary, a mechanical stop means 49 or and the guide rods 39 and and the bracket 40, otherwise the

Carriage 81 is a frame which receives the front and rear Aufkimmhalterung 2 and below a rail means 52 which engages in a rail holding means 53 which is mounted in the individual steps of the staircase 8 or the platform 80. The carriage 81 may further comprise a wheel set 54 which supports the carriage 81 when moving or when releasing it from the watercraft, the carriage 81 on land

can be used.

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

Embodiments limited.
