Description

The present invention relates to a Wassersportzuganlage, in particular a circulating water Sportzuganlage.

Wassersportzuganlagen are known in different versions. All have in common that they have at least one revolving endless rope, which is guided over masts mounted pulleys, one of these sheaves is driven by a motor. These masts are in this case arranged in a body of water usually near the shore and the sheaves are attached to these at such a height that with the continuous endless rope to which tows are detachably mounted, water sports, such as. Wakeboarder or water skier, are pulled across the water.

Such a Wassersportzuganlage discloses, for example, the DE 10 2012 106 575 A1 , This known system has an endless traction cable and a parallel extending endless auxiliary rope, the sheaves of both ropes are mounted independently. So that the ropes can circulate, a pulley, over which the pull rope is guided driven. The auxiliary rope and the traction cable are coupled together by means of cable ropes, so that the auxiliary rope is pulled by the traction cable.

A problem, especially for beginners, has been found to be the fact that the sheaves have a constant diameter, so that the deflection of the rope takes place according to the diameter of the sheave. However, the diameter of the pulleys is relatively small in the speed with which a person is pulled by the rope across the water surface. The abrupt deflection of the rope on the sheave therefore often leads to falls, since the forces occurring as a result of the deflection can not be controlled by the driver. Furthermore, due to the small deflection radii of the pulleys, high loads occur, in particular during load changes of the rope, so that the service life of the individual components of the water sport pulling system is shortened.

The present invention is therefore based on the object to provide an improved Wassersportzuganlage available.

If appropriate, the described embodiments and developments can be combined as desired. Further possible refinements, developments and implementations of the invention also include combinations, not explicitly mentioned, of features of the invention described above or below with regard to the exemplary embodiments.

The accompanying drawings are intended to provide further understanding of the embodiments of the invention. They illustrate embodiments and, together with the description, serve to explain principles and concepts of the invention. Other embodiments and many of the stated advantages will become apparent with reference to the drawings. The elements of the drawings are not necessarily shown to scale to each other. The same reference numerals designate the same or similar components.

Fig. 1 shows a schematic view of a Wassersportzuganlage 1 according to an embodiment of the present invention. The Wassersportzuganlage 1 is particularly designed as a circulating water sports train, which is provided with a rope 10, which forms a loop and thus a circuit on a body of water 15. The Wassersportzuganlage 1 is provided a body of water 15 and preferably has a plurality of masts 2, between which the rope 10 is stretched and is deflected to the masts 2 each. The masts 2 are provided near the shore and extend across the water 15th

Further, a second cable 12, also referred to as auxiliary rope, is provided, which is coupled to the cable 10, also referred to as the main cable, via driver 13. By means of attachable to the cable 10 facilities, it is possible to draw a person 14 on the water surface of the water body 15. On the masts 2 deflecting devices 100 are provided, which are designed to deflect the cable 10 and the cable 12. A respective deflection device 100 has at least one first pulley 11 for receiving a first portion of the rope 10, and at least one second pulley 21 for receiving a second portion of the rope 10. The first pulley 11 and the second pulley 21 are rotatably mounted in a carrier 30. The carrier 30 is mounted horizontally rotatable with respect to the mast 2.

Fig. 2 shows a schematic plan view of a deflecting device 100 according to an embodiment of the present invention. The deflection device 100 serves to deflect the cable 10 from a first direction R1 to a second direction R2. The deflection device 100 has a first cable pulley 11 for receiving a first section of the cable 10, and at least one second cable pulley 21 for receiving a second section of the cable 10. The first pulley 11 and the second pulley 21 are in a carrier 30th rotatably mounted. The carrier 30 is horizontally rotatable with respect to a main carrier 40, which is coupled to the mast 2 stored. For this purpose, the deflection device 100 has a joint 50, which is preferably provided in the middle of the carrier 30. The hinge 50 is in turn connected to the main carrier 40, which is connected to the mast 2. For example, if the load on the rope 10 increases, for example, by a rider loading the rope on the right side of the diverter 100, it is possible for the right portion of the carrier 30 to reach the rope 10 coming from the direction R1 is pivoted, wherein the left portion of the carrier 30 is pivoted away from the direction R2. In this way it is possible to compensate for load changes in the rope 10, which are caused, for example, by a slalom ride over the waters 15 trailed person, particularly well.

By providing such a deflection device 100, it is possible to increase the radius of curvature when deflecting the cable 10 on one of the masts 2 in comparison to a deflection by means of a single sheave. It is therefore possible to redirect the cable 10 more smoothly and over a longer distance than in comparison to existing systems which have pulleys with a constant diameter. Therefore, it is advantageous to less falls and it reduces the maintenance costs of the system.

Further, since pulleys are used instead of sheaves, the maintenance of the entire water sport tow facility is simplified because the pulleys are reduced in size and weight and therefore are less expensive and easier to handle. Moreover, the pulleys arranged in a kind of roller rocker enable a continuous contact pressure of the rope pulleys 11 and 21 on the rope 10, whereby a lifting of the rope 10 with respect to the pulleys 11 and 21 is excluded. This increases the reliability of the system.

Moreover, the risk of injury to the operator of the system and / or the people dragged is reduced because the pulleys 11 and 21 have a smaller diameter compared to the sheaves. Moreover, the safety is increased because the pulleys 11 and 21 have no spokes in comparison to pulleys, which can represent a further risk of injury. Furthermore, the cable 10 is guided by at least two pulleys 11 and 21, and is therefore better protected against unwanted derailment.

In this embodiment, 30 spring means 60 and damper means 70 are provided on the carrier, which are adapted to cushion and / or dampen rotation of the carrier 30 with respect to the main carrier 40, which is coupled to the mast 2. The main carrier 40, in which the carrier 30 is rotatably supported by means of a joint 50, is coupled directly to the mast 2. The spring means 60 and the damper means 70 are pivotally connected to the carrier 30 and to the main carrier 40. This makes it possible to cushion and / or dampen rotation of the carrier 30 with respect to the main carrier 40 and the mast 2. In this way, a rocking of the carrier 30 and the mast 2 can be prevented, and load changes in the rope 10 can be cushioned and damped particularly well in this way. The spring means 60 and the damper means 70 may also be arranged between the main carrier 40 and the mast 2, or between an intermediate carrier 45 and a main carrier 40, as shown in FIGS Fig. 8 or the Fig. 12 , be provided.

In the presentation of the Fig. 4 it can be seen that the carrier 30 has a curved shape in this embodiment. Preferably, the carrier 30 is bent in the direction of the rope 10. In this way, the forces acting on the first pulley 11 and the second pulley 21, particularly well received and forwarded to the main carrier 40 and the mast 2.

The sealed bearing 90 is, for example, a rolling bearing, and is sealed so that no further lubrication is necessary, and that no foreign matter or contaminants can penetrate into the interior of the bearing 90. Furthermore, the bearing 90 of the pulley 11 is sealed so that no oil or grease can escape from the bearing 90, and z. B. can contaminate the water 15. In particular, the bearing 90 is designed such that it can be stored horizontally, without the oils and fats can escape from the bearing 90.

Furthermore, the pulley 11 has a running surface 80, which is formed from a friction-increasing and / or noise-reducing material 120.

The side windows 110 extend outwardly from the tread 80 at a distance corresponding at least to the rope diameter. For example, a side window 110 extends from the tread 80 at a distance that is twice or three times the rope diameter. The rope 10 has, for example, a diameter of 10 mm, and the side windows 110 extend z. B. 20mm to 30mm from the tread 80 of the pulley 11 to the outside. In this way, the cable 10 can be performed very safe in the pulleys 11. Furthermore, the side windows 110 may be coated with a material 130 which at least partially comprises plastic. In this way, the resistance of the side windows 110 and thus the pulley 11 can be improved. Furthermore, the noise development of the entire system is significantly reduced by this design of the side windows. For example, the side windows 110 are coated with PA6, PA66, PA6G, PE-LD, PE-HD, PE-UHMW and / or various rubber compounds. The base material of the side windows 110 may be, for example, a light metal alloy.
