Description

The invention relates to a device and a method for easy and secure attachment of a device carrier, preferably for dinghies, on a sailing or motor yacht and for safe transport of the attached devices while driving.

Such equipment carriers are used in particular for fastening and holding of dinghies, with or without motor, at the stern of sailing or motor yachts, which are carried along for safety of the crew and for safe landing on the shore.

1. 1. Das Beiboot liegt auf dem Bug des Schiffes.
2. 2. Das Beiboot liegt auf dem Kabinendach.
3. 3. Das Beiboot ist mit einer Leine an die Segelyacht oder das Motorschiff angehängt, bevorzugt am Heck oder während der Hafenmanöver oft auch an der Seite mit einer Leine zur Bug- oder Mittschiffs-Klampe.
4. 4. Das Beiboot wird an Davits hängend mitgeführt.

Conventional methods for carrying a dinghy are based on the following principles:

1. 1. The dinghy is on the bow of the ship.
2. 2. The dinghy is lying on the cabin roof.
3. 3. The dinghy is attached with a leash to the sailing yacht or the motor ship, preferably at the stern or during the harbor maneuvers often also on the side with a leash to bow or midships cleat.
4. 4. The dinghy is carried on davits hanging.

All of the above-mentioned types of entrainment have significant disadvantages.

If the dinghy is transported on the ship itself (1 and 2), the skipper and the crew will be obstructed in your view forward. Depending on the size of the dinghy, this visual obstruction is not responsible for safety reasons or hinders necessary maneuvers.

Furthermore, the dinghy occupies valuable space on the naturally crowded areas of ships. As a rule, the dinghy is stored in the area of the working area in the bow area. This is accompanied by several dangers. For one, the crew may be necessary to work on problems with the headsail, gennaker or spinnaker for lack of space only perform restricted. On the other hand, the foresail liners (pods) can get caught in sailing boats in the dinghy.

The launching of the dinghy is often only possible by at least two crew members by laborious and time-consuming work.

In the third solution, the dinghy is moored by a leash at the stern of the yacht. From about 20 knots wind speed (equivalent to wind force 4) and corresponding sea state, the dinghy can be lifted off the water and thrown through the air, possibly damaging important parts of the ship, injuring the crew or tearing the tug line. In the worst case, the dinghy is lost.

When attaching the dinghy of the ship or from the bow cleat, it may happen that the dinghy under the hull of the ship and thus damage the dinghy and the hull of the ship, possibly at the bow thruster or the propeller possible ,

The necessary outboard of the dinghy must be temporarily dismantled in these three alternatives and stowed separately. For safety or environmental reasons, exceptions are not possible even with the third alternative.

While the outboard motor would not necessarily degrade in the fourth solution, the davits solution is expensive over the other solutions and requires space on board for the davits, making them practical only on larger yachts and ships.

None of the yacht manufacturers and shipyards has taken up this problem so far although some safety-related problems can arise.

An alternative solution for a holding device is disclosed in US Pat. US 5,018,475 described. About a detachable connection two arms of a holding device are hung on the dinghy in two eyelets on the platform of the yacht and prevented by a spring-actuated snap on slipping out of the eyes. As a result, a more or less firm connection between dinghy and yacht is created, which allows only one turn around the axis connecting both eyelets. In the German patent application no. 10 2012 006 766 A1 has already been described to the above solutions simplified mechanical holding device. Its content is fully incorporated herein.

• einer Anzahl von Auslegern (d.h. einer oder mehrere, bevorzugt mindestens zwei, aber auch drei oder mehrere) mit einer hakenförmigen Kupplung, die an dem Beiboot oder Anbauteil feste oder abnehmbar angebracht sind
• einer Anzahl von Aufnehmern (d.h. einer oder mehrere, bevorzugt mindestens zwei, aber auch drei oder mehrere), die mindestens eine Kupplungsachse umfassen und am Heck oder einem dort feste installierten Anbau des Schiffes so angebracht sind, dass die Ausleger mit der hakenförmigen Kupplung in die Kupplungsachse eingehängt und durch Drehung des Auslegers oder des Aufnehmers um die Kupplungsachse ab einem bestimmten Drehwinkel wie in Anspruch 1 definiert arretiert werden.

The invention has for its object to develop an improved holding device with which a dinghy or other entrained attachment in the rear of a ship can be carried even safer and easier. According to the invention the object is achieved by a holding device according to claim 1. The required for attachment of the dinghy or releasably entrained attachment to the ship mechanics of the holding device consists of two essential parts, namely:

• a number of cantilevers (ie, one or more, preferably at least two, but also three or more) with a hook-shaped coupling fixedly or removably attached to the dinghy or attachment
• a number of transducers (ie one or more, preferably at least two, but also three or more) comprising at least one coupling axis and are mounted at the rear or fixed there fixed attachment of the ship so that the boom with the hook-shaped coupling in the Mounted coupling axis and locked by rotation of the boom or the transducer about the coupling axis from a certain angle of rotation as defined in claim 1.

In the case of several receivers, according to a preferred embodiment, they are mounted at the same distance as the outriggers on the dinghy or an accessory to be carried, so that in each case one jib can engage in a corresponding attachment. If more transducers than cantilevers are included in the system, they are preferably arranged so that at least two cantilevers can engage in two corresponding transducers. The free transducers can either be used for additional attachments or serve for the different positioning of the dinghy or the attached attachment.

As an alternative to the previous embodiment, it is also possible to mount two or more arms in a pick-up, if it is designed, for example, as a single rod, in which several arms can engage simultaneously.

For this purpose, the transducer, for example, from a tube or a rod with 10 to 100 cm in length, preferably about 10 to 20 cm for a coupling of individual arms or about 50 to 100 cm, in particular about 60 to 70 cm, for the coupling of two or more outriggers to be in the same pole. This variant is cheaper to produce, easier to attach to the ship and more versatile than single, especially in width to the boom adapted transducers and have the same functionality. However, due to the lack of lateral support, the fixation of the Dinghy or attachments are somewhat uncertain, the general locking can be done as well.

The general principle of the holding device according to the invention will be described in more detail below with reference to the entrainment of a dinghy, without limiting the holding device to this application. The stern of the dinghy is lifted either directly or by use of a leash and the outriggers are hooked into the receivers on the ship, in particular a motor or sailing yacht (hereafter simply referred to as "yacht"). As will be shown in the description, this principle is particularly suitable for smaller yachts, for example, yachts with a length of up to 20 meters.

The pickups on the yacht have two major advantages. The construction results in a kind of fishing hook, which allows to lay the boom without much effort on the pick-up and mount in the coupling axles. Thus, the dinghy is ever provisionally secured to the yacht.

The dinghy is towed forward in an approximately upright position via a cable pull in the aft area or on the mast of the receiving ship and at the bow of the dinghy. The dinghy is thus connected at the rear with the stern of the receiving yacht. With the bow it stands at an angle between 45 ° and 90 ° upwards.

Due to the shape and type of hook-shaped coupling in the boom when pulling the dinghy first the dinghy is pushed with the boom mounted on the main axis to the stop of the hook-shaped coupling. Then the dinghy is pulled up at its bow. In this case, the bow of the dinghy moves arcuately together with the boom on the main axis upwards and the hook-shaped coupling rotates about the coupling axis in a locking position in which slipping out of the hook-shaped coupling is prevented by the coupling axis. The weight of the dinghy and the special design of the hook-shaped coupling of the boom or the transducer lead to a very firm connection of the boom and the transducer in the locking position. Even with high wind forces up to about 35 knots no problem could be determined. Also with mechanical load of the clutch by, eg wind, swell, Kränkung or other influences, the dinghy can not be moved at the rear in the locking position. It is thus secure and firmly locked.

By virtue of the fixed lock and the simple mechanism, it is now also possible to use heavy dinghies (for example greater than 70 kg) or to leave an engine (for example outboard motor) on the dinghy while the dinghy is being transported in the holding device according to the invention.

The holding device according to the invention allows the dinghy by a few steps, carried out in reverse order to water again. If today an effort of two crew members, a lot of strength and time is necessary, so the holding device according to the invention allows this in a few minutes by a person with almost no use of force. The effort is much less and the process is easy to perform even by physically weaker crew members.

The carrying of a dinghy at the stern of the yacht no longer obstructs the view of the skipper and the crew, as it is no longer on the bow or canopy in direct line of sight forward.

Since the dinghy is no longer hoisted on deck or no longer needs to be launched from the deck over the sea fence, the risk of destroying the sea fence or dinghy during the handling of the dinghy is lifted.

The risk of losing the dinghy is significantly reduced. It is securely fastened and is not driven by higher wind forces. The risk of injury or damage in case of storm is reduced by a dinghy flung through the air.

The only limited on the ship space or required for maneuver work surface is not further reduced by the dinghy. A catching of the pods on the dinghy during a sailing maneuver is excluded.

Due to the above-described simple operability and secure locking possibility of the holding device according to the invention, this can be used according to a further aspect of the invention also for additional applications on ships, especially motor and sailing yachts. Here, the boom for Bracket for bath or fishing platforms, barbeque platforms, bicycle or two-wheel carriers (eg for light mopeds or electric bicycles), solar panels, tables and similar equipment. The underlying principle is the same as described above for holding a dinghy at the stern of a yacht. These brackets can also be used for mounting attachments, for example in the bow area or side area of a ship. The advantage is that the holding device can be used in a variety of ways, that the attachments can be carried outboard and held securely. For example, when using a platform as a grill platform a grill (eg typical Weber gas grill) can be used completely outboard and stowed back on board after use. This measure increases the safety in its use.

Further embodiments of the invention will become apparent from the following description of preferred embodiments of the holding device according to the invention.

According to the invention, the receivers in addition to the coupling axis on a blocking device, such as a blocking axis or a blocking plate. The blocking device intervenes, for example, in the hook-shaped coupling and prevents linear movement of the respective arm in Arretierungszustand, preferably after rotation of the boom by about 25 to 40 degrees from the horizontal, more preferably by about 27 to about 35, in particular from about 30 degrees , For example, the blocking device has then entered the recess of the hook-shaped coupling on the boom so far that it would abut the nose of the hook-shaped coupling in a linear movement and thus prevents slipping out of the hook-shaped coupling from the coupling axis. The angle of rotation, from which such a blockage should occur, by the position of the blocking device, for example in a preferably parallel to the coupling axis mounted blocking axis, or by the particular shape of the blocking plate, preferably an S-shape extending from the rear wall portion of the pickup snaking upwards and attached to the coupling axle, to be determined. The above values for rotation to stall are merely preferred values which may be chosen to be smaller or larger for other applications such as special attachments or dinghies.

According to a further aspect of the holding device according to the invention this is designed so that the dinghy or attachment during travel by means of a fixed at one of the attachment points of the boom point fixed cable in locking position, preferably in a rotation angle between 30 and 90 degrees, relative to the horizontal Location of the dinghy or attachment, is held. In order to prevent accidental slipping out of the coupling axis, it is preferred that the angle of rotation is slightly greater than the smallest angle of rotation suitable for securing.

According to a further aspect, the holding device according to the invention can have outriggers each on the starboard and port side of the transom of the dinghy, which are attached pointing away from the dinghy with the hook-shaped coupling. By using two cantilevers and corresponding transducers, improved stability can be achieved. This is particularly useful for heavier or far-reaching crops. When using an outboard, it can be mounted between the two outriggers and will work even if the jib is fixed to the dinghy. To provide sufficient space for an outboard, the booms are preferably located at a distance, viewed from the center of the dinghy, of between 25 cm and 50 cm to the left and right. This results in a distance of the two arms of about 50 cm to 100 cm, depending on the width of the dinghy. More preferably, for example, the vertical distance is normalized to 70 cm to provide a replaceable holding system in which multiple dinghies or attachments can be used interchangeably with the same system. The interchangeability and a standard of 70 cm ensure the use of the system with all currently common dinghy with mirror.

For attachment to the mirror of a dinghy L-shaped construction of the boom is expedient, the smaller leg is preferably fixed or removable connected to the mirror and the longer leg has the hook-shaped coupling. Both legs preferably include an angle of about 80 and 90 degrees, so that the longer leg preferably points away from the mirror of the dinghy approximately in the horizontal. For common inflatable boats, the angle is about 83 degrees.

The height at which the two outriggers are attached is approximately equal to or slightly above the water surface of the floating dinghy.

Exemplary boom materials are square or rounded square or square plastic, carbon fiber, aluminum, stainless steel or sheet steel tubing to provide stability. The edges are preferably rounded, since thereby the stability of the construction can be further increased. Alternatively, pipes in round or oval shape or U- or I-shaped support elements for the boom can be used. For example, to ensure the stability and functionality of the hook-shaped coupling, optionally a square tube can be welded to the ends of such a boom.

More preferably, the boom can have an extendable arm (longer leg), which is composed of two mating and fixable together with each other mold tube parts and at the end of the hook-shaped coupling is arranged. On the short leg, these have a mounting unit for attachment to the mirror of a dinghy. Through the use of clip-arm boom elements, the length of the boom can be adapted to the structural conditions of the dinghy. Due to the possible displacement and locking, such as by means of conventional snap or snap fasteners, other snap fasteners or fixed locking options, the long leg of the boom, the distance of the dinghy can also be adjusted during transport, for example, to create more space at the rear or to get closer to the quayside with the stern.

According to a preferred embodiment of the holding device according to the invention, the one or more receivers of a U-shaped base member made of plastic, carbon fiber composite material, aluminum, stainless steel or sheet steel, which is fixed or rotatably mounted connected to the ship. When the base member of the susceptor is rotatably supported, the rotation serves to lock the hinged arm as described above. In this case, after the rotation of the basic component of the pickup in a locking position this also to lock, to ensure a backup of the coupling of the pickup with the boom. When the boom is rotated about a fixed receiver, however, for example, the tether on the bow of the dinghy takes over this security function.

Preferably, the U-shaped base member has at least one coupling axis and at least one locking axis or at least one blocking plate between the two side parts, wherein the boom is hooked with the hook-shaped coupling in the coupling axis rotatable. The arrangement of the coupling axis and the blocking axis in the pickup are adapted to the shape and cutout of the hook-shaped coupling part, so that after a rotation of about 30 degrees, the blocking axis prevents slipping out of the hook-shaped coupling part of the boom from the coupling axis of the pickup. For example, blocks the blocking axis or the blocking plate a linear movement of the coupling part in the locking position, but allows this movement in the non-rotated state (initial state when mounting the boom in the transducer).

For a convenient arrangement of the holding device, in particular for the transport of a dinghy or a bathing platform, it is advantageous if the one or more transducers are mounted either outside the rear or sunk in the stern of the ship, as they are thereby in most maneuvers out of the way and thereby the risk of injury is reduced. The transducers can either be attached directly to the ship or they can be mounted on an existing platform in the rear area. When mounted directly on the stern or on a platform, they may be provided with a protective and reinforcing element, e.g. made of wood or plastic, be sheathed to prevent injury or to prevent damage. For this purpose, the U-shaped basic components can be encased or directly in a sinking at the rear, e.g. a tailgate, are mounted so that only recesses are exposed with the coupling axis and the optional locking axis, in which the arms are mounted.

Manufactured by, for example, companies in the metal, plastics, carbon fiber composites and wood industries. After completion of the metal parts, they are treated by a suitable process against environmental influences (in particular seawater), e.g. anodized. Some elements of the invention may be either aluminum, stainless steel, steel, carbon fiber composites, wood or impact resistant plastic as long as they are seawater resistant (salt water).

In the FIG. 1 an application of the holding device according to the invention is shown. At the stern 18 of a ship 17, the transducer 19 is fixedly mounted as the first part of the holding device according to the invention. The transducer is detachably connected to the second part of the holding device according to the invention, namely the boom 20. The boom 20 is firmly fixed to the dinghy 16 mirror. The dinghy is pulled up over a line, not shown, and held in this locking position (rotation angle α about 80 degrees).

The dinghy to be attached part of the holding device according to the invention is referred to as a boom. FIG. 2 shows a side view of a boom, as it can be used in the holding device according to the invention. The boom is moored to the stern of the dinghy, the mirror, fixed or removable again.

The boom shown here consists of two parts. A part of the boom is assembled from two separate pieces into a nearly rectangular, L-shaped part. In this case, square (shown here), round or rectangular shaped tubes are used. This part is called mounting leg 1.

The second part of the boom extends part of the L-shaped mounting leg 1. This part is also made of square (shown here), round or rectangular shaped tubes and is used for easy length adjustment. For this purpose, the two parts of the boom are designed to slide into each other. Due to the possible displacement of the movable part of the boom, the distance to the yacht can be adjusted. The extending part of the boom is also referred to as a long leg 2 and comprises at its end the hook-shaped coupling 3. Both parts 1 and 2 together form the boom.

The hook-shaped coupling 3 is in FIG. 3A Enlarged in side view so that you can see the shape of the cutout. FIG. 3B shows the hook-shaped coupling in front view, wherein the hollow body 4 of the boom is clear.

The matching to the boom pickup 6 is moored at the stern of the yacht (see FIG. 4 ). The boom is hooked with the hook-shaped coupling 3, here a hook-shaped cutout, in the coupling shaft 7 of the pickup on the yacht.

FIG. 4 shows a sensor 6 can be used according to the invention, which has two axes between two parallel sides of the U-shaped arrangement, namely a coupling axis 7 and a blocking axis 8. FIG. 5 shows the axis positions from the side. The coupling shaft 7 serves to hook the hack-shaped coupling on the boom and as a rotation axis for the boom in the lock. The second axis is referred to as the blocking axis 8 and ensures the firm locking of the boom after a rotation of about 30 degrees.

Both axes can have different thicknesses and a specific arrangement. The coupling shaft 7 must carry the load of the dinghy and is therefore executed in three to four times the strength compared to the blocking axis 8. The blocking axis serves to lock, that is prevents a linear displacement of the boom in the locking position, and carries no load. That's why she can be thinner than that Be clutch axis. The blocking axis 8 is located at a certain distance and angle to the main axis, so that a lock when turning the hinged arm can come about. This will be discussed in more detail later.

FIG. 6 shows the transducer with the two axes 7 and 8 from below and FIG. 7 from the front.

The FIG. 8 shows the transducer when installed. The U-shaped base member of the transducer with the two axes is embedded in a left and right protection and reinforcing element 11.1 and 11.2, to provide additional stability for the construction and to ensure the safety of the boat operator and the passengers. The two elements 11.1 and 11.2 are made here, for example, from seawater-resistant plastic, with wood, metal or composite materials would also be suitable.

In the FIG. 9 the function and the interaction of the individual components of the holding device according to the invention become clear.

The boom (more specifically, the long leg of the boom, hereinafter referred to as 2) is secured to the stern of the dinghy (not shown). With its end, the hook-shaped coupling 3, this is mounted in the receiver 6, which is attached to the stern of the yacht. In this case, the cutout of the boom comes to rest on the coupling shaft 7 of the receiver 6 (not shown) at the stern of the yacht. Yacht and dinghy are now tail to stern and the dinghy is mounted with the boom 2 in the receiver 6.

The next step is to try to pull it up by pulling on the bow of the dinghy with a leash at the bow of the dinghy. The leash can run from the bow of the dinghy towards the top of the mast and from there via a winch into the cockpit of the ship. There, the rotational position of the dinghy can be determined with the help of Winches. If no Dirk is available for yachts, then a winch that has been moored on the backstay can be used for this purpose.

Due to the resulting forces and their directions and by the arrangement of the axes (pins) in the transducer 6 and by the shape and type of cutout in the boom 2, the boom 2 is on the coupling axis 7 when pulling up the dinghy pushed to the end of the cutout. After this horizontal, linear movement through the end of the cutout space is no longer given, the pulling movement is now implemented at the bow of the inflatable boat in a rotational movement on the coupling shaft 7 of the pickup. The bow of the dinghy is pulled up. In this case, the boom 2 moves arcuately on the coupling shaft 7 upwards.

The outer nose of the boom 2 is now pressed against the blocking axis 8 in the transducer 6. The larger the arcuate angle, relative to the horizontal, is, the further the nose is now turned on the boom in the blocking axis of the pickup. Is the dinghy in a position of about 30 degrees to the horizontal (approximate position in FIG. 8 ), so the cutout has pushed so far on the blocking axis 8 that the boom 2 can no longer slip from the coupling shaft 7 of the pickup 6. The dinghy can no longer be removed from the mount by a linear movement. It can then be pulled up to about 80 degrees. Then it is completely secured.

The blocking axis 8 serves to prevent the linear movement of the suspended in the coupling shaft 7 boom 2, which are transmitted to the boom in particular in wind, waves, injury to the vessel or other shocks on the boat. By locking with the aid of the blocking axis 8, however, this linear movement is prevented, so that by simple means a significantly increased safety is ensured with respect to a safety device based solely on the principle of gravity (for example, without a second axis).

As an alternative to the above-mentioned holding device with two axes, namely a coupling axis and a blocking axis in the pickup, the holding device according to the invention may have a sheet for locking the boom instead of the blocking axis. The FIG. 10 shows such an alternative embodiment of a holding device according to the invention. The holding device is up to the alternative solution of the blocking device analogous to that in the FIGS. 4 to 9 shown retaining device, except that it has an S-shaped locking plate 9 for locking the boom 2 in the locking position (shown here). The S-shaped plate is bent from the rear part of the pickup 6 in such an S-shape upwards and attached to the coupling axis 7, that the nose of the hook-shaped coupling 3 in engages the locking position behind the sheet and thus prevents slipping out of the boom of the coupling axis due to a linear movement.

The holding device shown in the figures can also be used for transport and to secure other attachments, such as, bathing platforms or brackets for solar panels, etc., where the same principle of locking can be applied. The exemplary explanations with reference to a dinghy served merely for a detailed description of the general principle of the holding device according to the invention and the person skilled in the art knows further embodiments and application examples for this holding device. In particular, this is not only available at the stern of a yacht, but can also be used in other areas of a yacht. The invention has significance for all owners of sailing or motor yachts, especially for those up to a length of about 20 meters. Through the possibility of locking "rear to rear" is a subsequent retrofitting a sailing or motor yacht with the holding device according to the invention is possible at any time.
