Description

The invention relates to a Wasserstrahlumlenkvorrichtung for connection to a floating device, such as a jet ski or a boat, with a water jet drive for generating a water jet. About such Wasserstrahlumlenkvorrichtung an external device, such as a sports device for transporting people, be connected to the floating device such that the water jet is passed from the floating device on the Wasserstrahlumlenkvorrichtung to the external device, or forwarded.

State of the art

In the US 7,258,301 B2 a water sports equipment is described, which consists of a special boat unit and an external flight unit. Water is drawn in from the boat unit via a high-performance pump and passed on to the flying unit via a hose. This flying unit can be strapped to a person's back. The water drawn in by the boat unit is forwarded as a jet of water via the hose to the flying unit. The jet of water is ejected again via two manually controllable nozzles on the flying unit. By means of the recoil principle, the person rises depending on the position of the nozzles and the adjusted power of the high-performance pump in the height.

By the WO 2013/041 787 A1 is a Wasserstrahlumlenkvorrichtung, which consists of a pipe system, known for connection to a jet ski. By means of this Wasserstrahlumlenkvorrichtung the external flight unit can be connected to a commercial jet ski. To do this, the jet of water is directed forward from the rear, ie from the stern, of the jet ski at the bottom of the jet skis. Alternatively, in the WO 2013/041 787 A1 proposed that the Wasserstrahlumlenkvorrichtung can be permanently installed in the jet ski and thus on pipes, which run in the hull of the jet ski is realized.

A disadvantage of these known systems is that special boot units are required for the connection of the external aircraft. In addition, by a arranged below the jet ski or boat pipe or hose arranged swimming behavior, such as the ability to bend, the jet ski or boat is also adversely affected.

DESCRIPTION OF THE INVENTION: Problem, Solution and Advantages

The invention has for its object to further improve a Wasserstrahlumlenkvorrichtung for connection to a floating device with a water jet drive for generating a water jet, the Wasserstrahlumlenkvorrichtung with little effort is removable and thus recoverable and wherein neither the swimming behavior nor the slip ability of the floating device through the water jet deflection is adversely affected.

This object is achieved with a Wasserstrahlumlenkvorrichtung according to claim 1 of the present invention.

According to the invention, a water jet deflecting device is provided, which is designed for connection to a floating device, for example a jet ski or a boat, with a water jet drive for generating a water jet. The Wasserstrahlumlenkvorrichtung has a deflection piece for deflecting the water jet, a first line piece for guiding the water jet and a connector for connecting the Wasserstrahlumlenkvorrichtung with an externally connectable device, such as a sports device and / or aircraft for passenger transport on.

The first line piece is arranged between the deflecting piece and the connecting piece and connects the deflecting piece with the connecting piece for forwarding the water jet from the deflecting piece to the connecting piece. In this case, the first line piece is designed such that it can be arranged substantially along a first outer surface or outer surface of the floating device, wherein the first line piece is arranged in the arrangement of the water-floating device outside the water.

An external device, such as a sports device for transporting people, can over a long, for example, about 10 m long hose with the Wasserstrahlumlenkvorrichtung be connected. For this purpose, the hose is connected to the outlet of the connection piece of the water jet deflection device. The deflected water jet is thereby passed from the connector over the hose on to the external device.

The deflection piece forms the starting piece of the water jet deflection device. In this case, the deflection is so on the floating device, for. As the jet ski, connected, that it can absorb the water jet generated by the floating device. For example, the deflection device can for this purpose be flanged to the outlet nozzle of a jet ski or a boat with water jet drive. Preferably, the deflecting piece is at least partially tubular for this purpose.

In addition to receiving the water jet emitted by the floating device, the deflecting piece serves to deflect the water jet in another direction. Preferably, the water jet is deflected by an angle between 90 ° and 180 ° by the deflection piece. Usually, in a jet ski or a boat with water jet propulsion, the jet of water is ejected through a nozzle to the rear. The deflecting serves to deflect the water jet preferably in the substantially opposite direction, ie forward. For this purpose, the deflecting piece can be formed in any suitable manner. For example, the deflecting piece may be U-shaped. Furthermore, the deflector could consist of several sections and partially divert the water jet in each section with an angle, so that the resulting deflection corresponds to an angle between 90 ° and 180 °. For example, the deflecting piece could be designed such that the water jet is deflected in each case by 90 ° in two successive sections. Thus, the resulting direction of the water jet is deflected by 180 °.

The first line piece may be tubular or tubular and extends substantially over the entire length of the floating device, for example over the entire length of the jet ski or the boat. The first line piece is preferably formed substantially longer than the deflection piece or the connecting piece. The first line piece is connected to the output of the deflection, for example, flanged and essentially serves to forward the already deflected water jet in this preferred direction. A further deflection of the water jet through the first line piece is not provided here. Thus, it is preferably provided that the first line piece forwards the water jet along a substantially straight path. When forming the first piece of pipe as a hose can be provided along the route by an example, not rectilinear or wavy laying of the hose a divisional deflection. In the region of the outlet of the first line section, however, the direction of the water jet essentially corresponds to the direction of the water jet in the inlet area of the first line section. Thus, the preferred direction is not changed significantly by the first line piece.

According to the invention, the first line piece is designed such that it can be arranged along a first outer surface of the floating device. In this case, the first line piece may be directly attached to the first outer surface or connected thereto, as well as spaced along the first outer surface. For example, the first line piece can thus be arranged along the outer wall of a jet ski or a boat. Furthermore, the first piece of pipe may run on a jet ski or a boat along an outer surface. For example, the first line piece may be arranged at least partially along the foot region of a jet ski. A first outer surface of the floating device according to the present invention is to be understood as meaning that the first line piece is arranged outside the outer shell of the floating device. An arrangement of the pipe section within the floating device, for example, within half a hull, is therefore not provided. Under substantially along a first outer surface of the floating device according to the invention is to be understood that the first line piece over most of the length of the first line piece, for. B. over 80%, preferably 90%, more preferably 100% of the length of the first piece of pipe along a first outer surface of the floating device can be arranged.

Further, the invention provides that the first line piece is designed such that it is floating in the arrangement of the water Device is located outside the water or above a waterline or water surface. Since the first piece of tubing extends along a first outer surface of the floating device and is located outside the water when the floating device is in the water, the first piece of tubing is configured to be above the water surface and thus above when a water-floating device is installed the waterline runs. Preferably, the first line section runs completely outside the water and completely above the water surface or above the waterline. Under above the water surface or water line according to the invention is to be understood that the first line piece in a floating device in the water is then above the water surface or waterline when the floating device in the water is not charged or under normal conditions. By loading is meant, for example, that an additional weight, for example, by the placement of a person on a jet ski, is exerted on the floating device.

The fitting is connected to the output of the first piece of pipe. Furthermore, it is preferably provided that the connection piece is also arranged above the water surface or the waterline.

Since usually the outlet nozzle for the jet of water is arranged on a jet ski or a boat below the water surface or the waterline, the inlet opening of the deflecting piece or the initial region of the deflecting piece is arranged below a water-floating device below the water surface or the waterline. The deflection of the water jet through the deflection piece is thus preferably made not only by 90 ° to 180 °, but also upwards. "Upwards" in the context of the present invention also refers to a water surface, in the case of a device arranged in water or floating in water. Thus, the deflecting piece is preferably bent upwards or curved.

Characterized in that the Wasserstrahlumlenkvorrichtung can be arranged along a first outer surface of a floating device, the Wasserstrahlumlenkvorrichtung can be connected and installed in a simple manner to a commercial jet ski or a boat. Removing the Wasserstrahlumlenkvorrichtung or a zurückbauen in the normal function of the jet ski or the boat is associated with little effort. The externally connectable device, such as a sports device for passenger transport, can thus be easily connected by the inventive Wasserstrahlumlenkvorrichtung to any floating device with a water jet propulsion, such as a jet ski or a boat.

The fact that the Wasserstrahlumlenkvorrichtung invention is additionally designed such that this (at least the first line piece of Wasserstrahlumlenkvorrichtung) is located on the device floating in the water outside the water and thus extends above the water surface or the waterline, the floating behavior of the floating device For example, the jet skis or the boat, not negatively affected. Since the Wasserstrahlumlenkvorrichtung not below the water surface or the waterline along the floating device along, has the floating device through the installed Wasserstrahlumlenkvorrichtung no further or additional water resistance. Furthermore, this does not further increase the draft of the floating device. This is particularly advantageous in shallow waters. By changing the swimming behavior, for example, the turning ability of the floating device is to be understood. By virtue of the water jet deflection device which can be arranged according to the invention, the turning capability of the floating device, for example the jet ski or the boat, is not adversely affected.

A further advantage is that the installation of the Wasserstrahlumlenkvorrichtung can be made in a simple manner before the transport of the floating device to the waterhole, for example, to the river, sea or sea. A usually provided for the floating device transport, for example by means of a trailer, is by the Can not be hindered according to the invention can be arranged Wasserstrahlumlenkvorrichtung. The same of course applies to the return transport of the floating device, which can be carried out in a simple manner with installed Wasserstrahlumlenkvorrichtung. Furthermore, for example, a normal slipping on a trailer is possible. Thus, the transport behavior of the floating device is not adversely affected by the Wasserstrahlumlenkvorrichtung.

Preferably, the Wasserstrahlumlenkvorrichtung at least a first releasable connection means for connecting the connector with the floating device. In this case, the first releasable connection means serves firstly to attach the connection piece to the floating device and secondly to absorb tensile forces and / or to transmit tensile forces to the floating device. Thus, it is preferably provided that the first releasable connecting means is designed specifically for receiving tensile forces and / or for transmitting tensile forces to the floating device. For this purpose, the first releasable connection means may be formed, for example, as a rod, belt or steel cable.

The tensile forces that are absorbed by the first releasable connection means for connecting the connection piece with the floating device and / or are forwarded to the floating device are usually caused by the connected external device, for example sports equipment for passenger transport. The fact that the external device is connected by means of a long hose to the connector, occur sometimes large tensile forces at the junction between the hose and the Wasserstrahlumlenkvorrichtung.

For the purposes of the present invention, releasable connection means is understood to mean that a connection made with this connection means can be removed or opened again without destroying one of the two interconnected parts and / or the detachable connection means. For example, a detachable connection can be made by a screw connection.

Preferably, the connector is connected to the floating device by means of the first releasable connection means such that the fitting is in direct contact with the floating device, for example mounted on the floating device. Thus, the fitting may preferably be directly mounted on the outer surface of the floating device and connected to the floating device. Furthermore, it is preferably provided that the connection piece is arranged at a distance from the floating device, or can be arranged. Thus, the connector may for example be arranged in front of the bow of the floating device, for example in front of the bow of the jet ski, and spaced from the floating device and connected to the floating device by means of a rod or steel cable.

To accommodate the tensile forces, the connector preferably has a pull plate for connecting the first releasable connection means.

Furthermore, it is preferably provided that the pull plate has a hole, an eye, an opening or another suitable means for receiving the first connecting means. For example, the pull plate could have a substantially centrally disposed hole for receiving a shackle. A shackle may also be disposed on a bow nose of a jet ski or boat or similar floating device. By a rod or a wire rope, such as a stainless steel wire rope, the two shackles can be connected together. Here, the first releasable connection means thus consists of two shackles and a rod or a wire rope. By the pull plate, the tensile forces are absorbed by the externally connected via a hose device, forwarded to the connector and passed through the first releasable connection means to the floating device.

Furthermore, it is preferably provided that the water jet deflection device has a second releasable connection means for connecting the deflection piece with the floating device. This is the second one releasable connection means formed such that the deflection piece can be attached to the floating device, or connected to this, in order to receive the water jet emitted by the floating device. Preferably, the second releasable connection means is designed such that the deflection piece can thereby be connected to the floating device in such a way that the water jet emitted by the floating device is absorbed in its entirety. Thus, it is preferably provided that the outlet nozzle of the floating device is connected by the second releasable connection means close to the deflection piece. By "dense" is meant that the transition between the outlet nozzle of the floating device and the diverter is substantially dense so that all of the water jet discharged from the floating device is directed into the diverter and no or very little water the junction exits. For example, the second releasable connection means for connecting the deflection piece with the floating device may be formed as a clamp or flange.

Furthermore, it is preferably provided that the deflecting piece has a first portion with a water inlet opening and a second portion with a first water outlet opening. The individual sections may be formed as separate parts, such as pipes. Furthermore, the individual sections could be pipe sections and the deflection piece formed integrally.

Preferably, the first fictitious horizontal plane, which runs centrally through the water inlet opening of the first section of the deflecting piece, thus spaced apart, and preferably also parallel, to the second fictitious horizontal plane, which runs centrally through the first water outlet opening of the second portion of the deflection piece arranged.

Furthermore, it is preferred that the deflecting piece is designed such that, arranged in a water-floating device Wasserstrahlumlenkvorrichtung the lowest edge of the first water outlet opening of the second portion of the deflection above the uppermost edge of the water inlet opening of the second portion of the deflection is arranged.

Furthermore, it is preferably provided that the water inlet opening of the first section of the deflecting piece and / or the first water outlet opening of the second section of the deflecting piece is arranged such that the respective opening surfaces formed by the peripheral edges, the inlet opening surface and the outlet opening surface of the respective opening substantially parallel are mutually and substantially perpendicular to the first fictitious horizontal plane and the second fictitious horizontal plane.

Characterized in that the first fictitious horizontal plane, which runs centrally through the water inlet opening of the first portion of the deflecting below the second fictitious horizontal plane, which runs centrally through the first water outlet opening of the second portion of the deflection, is disposed above the first water outlet opening above arranged on a water surface, the water inlet opening of the deflection piece.

By forming a deflection piece in three such sections, the water jet received by the floating device through the deflection piece is deflected upwards and forwards and divided into two partial flows. Preferably, all three sections are tube-like. In this case, the first section preferably has a larger pipe diameter than the second and / or third section. Furthermore, it is preferably provided that the first portion is shorter than the second and / or third portion. Furthermore, the first section is preferably arranged substantially or at least partially perpendicular to the second and / or third section of the deflection piece. The three sections may be formed separately or represent portions of an integrally formed deflecting piece.

Furthermore, it is preferably provided that the second and third fictitious horizontal plane are substantially on an identical plane or at least parallel to each other and have a smaller-ren distance to each other compared with the distance between the first fictitious horizontal plane and the second fictitious horizontal Plane as well as the distance between the first fictitious horizontal plane and the third fictitious horizontal plane.

In principle, the deflection piece could also have more than three sections. For example, the water jet could be split into more than two sub-beams.

Preferably, the second portion and the third portion of the deflection piece are so connected to the first portion and arranged such that the second and third portion at least partially in a Angle smaller than 180 °, preferably between 175 ° and 45 °, particularly preferably between 140 ° and 90 °, to each other.

The water inlet opening of the first section of the deflection piece is connected to the floating device for receiving the water jet. The first water outlet opening of the second portion of the deflection piece is connected to a water inlet opening of the first line piece for forwarding the water jet. The second water outlet opening of the third section of the deflection piece is likewise connected to a water inlet opening of the first line piece or to a water inlet opening of a second line piece for forwarding the water jet.

Thus, it is preferably provided that the second portion and the third portion are at least partially, preferably with a substantial range, at an angle less than 180 ° and thus V-shaped to each other.

Furthermore, it is preferably provided that no third section is provided for the deflecting piece and the first section is arranged in such a way to the second section of the deflection that the water outlet opening of the second portion of the deflecting substantially on a fictitious vertical plane through the water inlet opening of the first portion of Deflection piece is or offset, in particular laterally offset, is arranged to such a fictitious vertical plane through the water inlet opening of the first portion of the deflection piece.

By providing a deflecting piece consisting of three sections, a first section having a water inlet opening and a second section having a first water outlet opening and a third section having a second water outlet opening, preferably a symmetrical distribution of the water jet laterally along the floating device or on the floating device allows become. By providing only two sections or an even number larger than three sections, however, an asymmetrical distribution of the water jet is achieved on or along the floating device.

Preferably, the connecting piece has a first water inlet opening, wherein the first water outlet opening of the second section of the Deflection piece is connected via the first line piece with the first water inlet opening of the connection piece. The first fictitious horizontal plane, which runs centrally through the water inlet opening of the first section of the deflecting piece, is preferably arranged below a fourth fictitious horizontal plane, which extends centrally through the first water inlet opening of the connecting piece.

Thus, it is preferably provided that the second fictitious horizontal plane, optionally a third fictitious horizontal plane and the fourth fictitious horizontal plane run essentially on an identical plane.

Further, it is preferably provided that the connecting piece has a second water inlet opening and this is connected via a second line piece with the second water outlet opening of the third portion of the deflection piece. Thus, it is preferably provided that the deflecting piece as well as the connecting piece each have three sections. In this case, the deflection piece has a water inlet opening and two water outlet openings for dividing the water jet into two partial beams. The water jet is forwarded via two separate line sections, a first line section and a second line section, preferably symmetrically, along the outer surface, for example laterally along or on a floating device to the two water inlet openings of the connection piece. In the connecting piece, the two-part water jet is again brought together in a single water jet and via a water outlet opening of the connecting piece, for example, via a hose to the external device, such as sports equipment for passenger transport, forwarded.

Since the connection piece, in contrast to the deflecting piece, is not provided for deflecting the water jet, the connecting piece can be substantially V-shaped or Y-shaped. Preferably, as well as in the deflection piece, in the connection piece all three sections are tubular. In this case, the first section of the connection piece with the water outlet opening preferably has a larger pipe diameter than the two second and third sections with the respective water inlet openings.

Furthermore, it is preferably provided that the second line piece, which connects the deflecting piece, or the second water outlet opening of the third section of the deflecting piece, to the connecting piece, or the second water inlet opening of the connecting piece, essentially along a second outer surface of the Floating device can be arranged or arranged on this second outer surface. Like the first line section, the second line section can be arranged on the second outer surface in such a way that, when the water jet deflection device is arranged on the device floating in the water, the second line section as well as the first line section are arranged outside the water and thus above the water surface or waterline.

The water jet deflection device preferably has a third releasable connection means for connecting the first line piece to the floating device. Further, the Wasserstrahlumlenkvorrichtung preferably has a fourth releasable connection means for connecting the second line piece with the floating device.

Preferred embodiment (s) of the invention

Fig. 1 shows an external device 40, namely a sports device for transporting people, which is connected via a long, about 10 m long, hose 41 with a floating device 200, namely a jet ski, with water jet propulsion means of a Wasserstrahlumlenkvorrichtung 100. The water jet generated and discharged by the floating device 200 is deflected via the Wasserstrahlumlenkvorrichtung 100, which is connected with its deflection piece 10 at the rear end 42 of the floating device 200, and two line pieces, a first line piece 11 and a second line piece 11 a, along the outer surfaces 14, 14 a of the floating device 200 from the rear 42 the floating device 200 to the bow 43 of the floating device 200 and passed from there via a connector 12 in the tube 41.

The externally connected device 40 thus the water jet is supplied via the hose 41. On the externally connected device 40 is as in Fig. 1 shown a person 47 strapped. The externally connected device 40 may further include a seat 44 for one or more persons 47. The water conveyed through the hose 41 to the externally connected device 40 is ejected downward through two nozzles, a first nozzle 45 and a second nozzle 46. These two nozzles 45, 46 are controllable by the person 47. Thus, the person 47 with the help of the externally connected device 40 can repel from the water surface 19 and rise up into the air. Thus, with the externally connected device 40, the sports equipment for passenger transport, depending on the length of the hose 41, a flight movement over water and partly over land can be performed.

By means of the water jet deflection device 100, an externally connectable device 40, for example a sports device for transporting persons, can be connected to any existing floating device 200, for example a jet ski or a boat, with a water jet drive.

As in Fig. 1 also shown, the Wasserstrahlumlenkvorrichtung 100 is formed such that the water jet is diverted by the deflector 10 from the outlet nozzle of the jet ski upwards. Thus, the water inlet opening 23 of the deflection piece 10 is disposed below the water surface 19 or waterline and the first water outlet opening 24 of the deflection piece 10 above the water surface 19 or water line. Also, the second water outlet opening 25 of the deflection piece 10 is arranged above the water surface 19.

The first line piece 11 as well as the second line piece 11a extend in the longitudinal direction of the jet ski along the outer surfaces 14, 14a of the Jetskis such that both the first line section 11 and the second line section 11a are arranged above the water surface 19 or waterline, or extend over the entire length thereof above the water surface 19. Thus, the Wasserstrahlumlenkvorrichtung 100 created no additional resistance below the jet ski or there is no additional obstacle in the bottom area of the jet ski. The floating device 200 thus retains its original curve ability and water stability and can continue to be used easily in shallow waters. Further, the water jet diverter 100 may also be mounted and installed prior to transport of the floating device 200. Transport by means of a conventional trailer is still possible without problems.

Fig. 2 1 shows the rear region 42 of the floating device 200, as well as the water jet deflection device 100 connected in the rear region 42 of the floating device 200 Fig. 2 the beginning of the water jet deflection device 100, namely the deflection piece 10, to see.

The deflecting piece 10 has three sections, namely a first section 21, a second section 22 and a third section 28. All three sections 21, 22, 28 are formed as tubes. The first portion 21 of the deflection piece 10 in this case has a tube with a larger diameter than the two tubes of the second portion 22 and third portion 28. The deflection 10 is with its first portion 21, or the water inlet opening 23 for receiving the water jet with the floating Device 200 connected. The second portion 22 and third portion 28 of the deflection piece 10 are each formed substantially longer than the first portion 21 of the deflection piece 10. By the second portion 22 and third portion 28 of the deflection piece 10 of the water jet from the first portion 21 of the deflection piece 10 is considered first redirected to the top and then forward. Thus, the water jet is deflected by two successive curved portions of the second portion 22 and third portion 28 of the deflection piece 10 each about 90 °. The resulting deflection of the water jet through the deflection piece 10 is thus approximately 180 °. Originally from the Jetski ejected backward water jet is thus deflected by the deflector 10 in the opposite direction, namely forward.

In order to achieve a deflection of the water jet not only forward but also upwards, the two sections, the second portion 22 and the third portion 28 of the deflection piece 10 are arranged at an angle 30 to each other. This angle 30 between the second portion 22 and the third portion 28 of the deflection piece 10 is smaller than 180 °. Thus, the two sections, the second portion 22 and the third portion 28 of the deflector 10 are V-shaped to each other. To increase the stability, a brace 36 is provided in the region of the V-shaped section between the second section 22 and the third section 28 of the deflection piece 10.

The first portion 21 of the deflection piece 10 has a water inlet opening 23, which is provided for receiving the water jet from the floating device 200 and is connected in this area with the floating device 200. The second portion 22 of the deflection piece 10 has a first water outlet opening 24, which is connected to the first line piece 11 for forwarding the water jet to the connection piece 12, or for forwarding the water steel to the bow 43 of the floating device 200. The third section 28 of the deflection piece 10 has a second water outlet opening 25, which is connected to a second line section 11a. The second line section 11a also serves to forward the jet of water to the bow 43 of the floating device 200.

Since the deflecting piece 10 is designed such that the water jet is deflected not only forward but also upwards, a first fictitious horizontal plane 26, which runs centrally through the water inlet opening 23 of the deflecting piece 10, below a second fictitious horizontal plane 27 and a third fictitious horizontal plane 29 arranged. In this case, the second fictitious horizontal plane 27 extends centrally through the first water outlet opening 24 of the deflection piece 10. The third fictitious horizontal plane 29 extends centrally through the second water outlet opening 25 of the deflection piece 10. Since the water jet according to Fig. 2 symmetrically distributed and diverted is, lie the second horizontal plane 27 and the third horizontal plane 29 substantially at a height, or on a plane.

Fig. 3 shows a floating device 200, namely a jet ski, in side view. At the floating device 200, the water jet deflection device 100 is connected. In the rear region 42 of the floating device 200, the water jet through the deflection piece 10 according to Fig. 2 deflected upwards and forwards. The first line piece 11 and the second line piece 11a are formed as tubes and extend on the outer surfaces 14, 14a of the floating device 200 along the longitudinal direction of the floating device 200. In this case, the two line pieces 11, 11a extend in the central region of the floating device 200 in or through the foot wells of the jet skis and in the front area, that is in the bow area 43 of the jet ski over the front deck.

Before the bow 43 of the floating device 200, the two pipe sections 11, 11 a are connected to the connector 12. The connecting piece 12 has two water inlet openings 31, 32 and a water outlet opening 33. Thus, the split water jet in the bow region 43 of the floating device 200 is brought together again by the connecting piece 12 into a single water jet. The fitting 12 is as in Fig. 3 seen, spaced and arranged in front of the nose of the floating device 200. For this purpose, a shackle is attached to the nose of the jet ski, on the one hand, and to a draw plate 20 of the connecting piece 12, on the other hand. Using these two shackles, the floating device 200 is connected to the connector 12 via a stainless steel wire rope. This first detachable connection means 15 serves for the one connection or fixation of the connector 12 in front of the floating device 200 and on the other for receiving and transmitting tensile forces from an externally connectable device 40 to the floating device 200.

Fig. 4 shows a V, or Y-shaped configuration of a connector 12 of a Wasserstrahlumlenkvorrichtung 100. The connector 12 has two water inlet openings, namely a first water inlet opening 31 and a second water inlet opening 32. These two water inlet openings 31, 32 are connected to the two line sections 11, 11a connected. In the connecting piece 12, the divided water jet is again brought together into a single water jet and discharged via the water outlet opening 33 of the connecting piece 12. At the water outlet opening 33 of the connector 12, for example, a hose 41, which is connected to an externally connectable device 40, are connected.

The fitting 12 according to Fig. 4 is tube-like. In this case, the output area, ie the area with the water outlet opening 33 of the connecting piece 12 has a larger diameter than the two input areas, namely the areas with the first water inlet opening 31 and the second water inlet opening 32 of the connecting piece 12. Between the two tubes for the inlet region of the water jet is a pull plate 20 fixed and thus not arranged detachably. The pull plate 20 is welded to the connector 12. The pull plate 20 has a centrally disposed hole 37. The hole 37 serves to receive the first releasable connection means 15 for connecting the connection piece 12 to the floating device 200. For example, the first releasable connection means 15 may thus comprise a steel cable which is connected directly or with the aid of shackles to the draw plate 20 of the connection piece 12 and on the other hand is in communication with the floating device.

The connector 12 has in the region of the two tubes for the input area, ie the two pipe sections, which have the first water inlet opening 31 and the second water inlet opening 32 of the connector 12, circumferentially formed around the pipe sections 38 for connecting the connector 12 with the first line piece eleventh and the second pipe section 11a. These areas 38 have a slightly smaller outer diameter compared to the remaining area of the same pipe section of the connecting piece 12. Thus, these area 38 are formed for connecting the connecting piece 12 with the pipe sections 11, 11 a trough-like.

Fig. 5 shows the connector 12 according to Fig. 4 with two connected line sections 11, 11a. In this case, the two pipe sections 11, 11 a, which are formed as tubes, in each case by means of three clamps 39 in the areas 38 for connecting the pipe sections 11, 11 a connected to the connector 12.
