Description

The present invention relates to a water sports train system, in particular a circulating water sports train system.

Water sports train systems are known in different versions. What they all have in common is that they have at least one revolving endless rope which is guided over pulleys mounted on masts, one of these pulleys being driven by a motor. These masts are usually located near the shore in a body of water and the sheaves are attached to them at such a height that water sports enthusiasts such as e.g. Wakeboarder or water skier being dragged across the water.

Such a water sports train system, for example, discloses the DE 10 2012 106 575 A1 , This known system has an endless traction rope and an endless auxiliary rope running parallel to it, the rope sheaves of both ropes being mounted independently of one another. A rope pulley, over which the pull rope is guided, is driven so that the ropes can run around. The auxiliary rope and the pull rope are coupled to one another by means of stay cables so that the auxiliary rope is pulled from the pull rope.

document AT 220 049 B discloses a towing system for practicing water skiing or skijoring by means of an endless tow rope, which is guided above the sliding surface via castors in a closed circuit and to which the usual holding ropes are attached. The fact that the sheaves have a constant diameter has turned out to be problematic, particularly for beginners, so that the deflection of the rope takes place according to the diameter of the sheave. However, the diameter of the sheaves is relatively small in terms of the speed at which a person is pulled by the rope over the water surface. The abrupt deflection of the rope over the sheave therefore often leads to falls, since the forces arising as a result of the deflection cannot be controlled by the driver. Furthermore, the small deflection radii of the rope sheaves result in high loads, in particular when the rope changes load, so that the service life of the individual components of the water sports train system is shortened.

The present invention is therefore based on the object of providing an improved water sports train system.

DISCLOSURE OF THE INVENTION

This object is achieved by a water sports train system with the features of claim 1. Advantageous further developments are the subject of the subclaims.

Accordingly, it is provided:
a water sports train system, in particular a circulating water sports train system, with: at least one mast, a rope which is deflected and / or driven on the mast and which is designed to pull a person over the water surface, a deflection device which is on the mast for the horizontal deflection of the rope is provided, wherein the deflection device has at least one first rope pulley for receiving a first section of the rope, and at least one second rope pulley for receiving a second section of the rope, the at least first rope pulley and the at least second rope pulley being rotatably mounted in a carrier, and wherein the carrier is mounted horizontally rotatable with respect to the mast.

By providing such a water sports facility, it is possible to increase the radius of the curve when the rope is deflected on the masts. It is therefore possible to deflect the rope more gently and over a longer distance than in comparison to existing systems which have rope pulleys with a constant diameter. As a result, the forces which act on the person and on the system when deflecting from a first direction into a second direction are reduced. Therefore, there are fewer falls and the maintenance costs of the system are reduced.

Since rope pulleys can be used instead of rope pulleys, the maintenance of the entire water sports train system is also simplified, since the rope pulleys are reduced in size and weight and are therefore cheaper to obtain and easier to handle. In addition, the rope pulleys arranged in a kind of rocker rocker enable the rope pulleys to be continuously pressed against the rope, thereby preventing the rope from being lifted with respect to the rope pulleys. This increases the operational safety of the system.

In addition, the risk of injury to the operator of the system and / or the people being towed is reduced, since the rope pulleys have a smaller diameter than the rope sheaves. In addition, safety is increased because rope pulleys are compared have no spokes for rope sheaves, which can represent a further risk of injury. Furthermore, the rope is guided by at least two rope pulleys and is therefore better protected against unwanted derailment.

According to an advantageous embodiment, a joint is provided in the middle of the carrier. This configuration makes it possible for the forces which act on the at least first rope pulley and on the at least second rope pulley to be transmitted symmetrically to the support and the masts. According to a further advantageous embodiment, the joint has one rotational degree of freedom or two rotational degrees of freedom or three rotational degrees of freedom. For example, the joint is designed as a swivel joint or egg joint or as a ball joint. Furthermore, the joint can also have one or more translational degrees of freedom. According to a further advantageous embodiment, the joint has exactly one rotational degree of freedom or exactly two rotational degrees of freedom or exactly three rotational degrees of freedom. In this way, the rope can be guided particularly securely in the rope pulleys and aligned and adjusted by the rope pulleys.

According to a further advantageous embodiment, spring devices and / or damper devices are provided on the carrier, which are designed to spring and / or dampen rotation of the carrier with respect to the masts. By providing spring devices and / or damper devices, load changes in the rope can be compensated particularly well. Furthermore, a possible rocking of the masts during the braking and starting process of the system is reduced. The spring devices and / or damper devices can be arranged directly on the carrier, or can also on other components, such as. B. on an intermediate support or on a main support, which are provided between the support and the masts.

According to a further advantageous embodiment, the carrier has a curved shape. For example, the carrier is bent in the direction of the rope. In this way, the carrier can absorb the forces of the rope particularly well and transmit them to the masts.

According to a further advantageous embodiment, the at least first rope pulley and / or the at least second rope pulley each have a running surface on which the rope is arranged, wherein the tread is made of a friction-increasing and / or noise-reducing material, in particular plastic. For example, the tread is made of PA6, PA66, PA6G, PE-LD, PE-HD, PE-UHMW and / or different rubber compounds. In this way, the noise level of the system is reduced, which makes driving on this water sports train system and operating this water sports train system more pleasant. Furthermore, this formation of a rope pulley minimizes the slip between the rope and the rope pulley, so that the wear on the rope and the rope pulley can be reduced.

According to a further advantageous embodiment, the at least first rope pulley and / or the at least second rope pulley has a sealed bearing. The sealed bearing is designed in particular as a sealed rolling bearing. This design of a rope pulley extends the maintenance intervals of the water sports train system, since it is not necessary to relubricate the bearings of the rope pulleys. The sealed bearing is designed in particular for high speeds. Furthermore, the bearing is advantageously sealed such that no foreign matter and contaminants can penetrate the bearing, and lubricants such as. B. oil or fat, can escape from the camp, and can get into the water.

According to a further advantageous embodiment, the at least first rope pulley and / or the at least second rope pulley has a diameter in the range from 10-50 cm, in particular in the range from 20 cm to 40 cm, and further in particular in the range from 28 cm to 32 cm , In this way, a particularly smooth running of the rope pulleys is ensured, since balancing the rope pulleys is not necessary due to the small diameter.

According to a further advantageous embodiment, the at least first rope pulley and / or the at least second rope pulley is / are at least partially formed from a light metal, in particular from an aluminum alloy, and / or at least partially from a plastic. The at least first rope pulley and / or the at least second rope pulley can also be formed at least partially or completely from plastic. The at least first rope pulley and / or the at least second rope pulley can also be designed as a hybrid component. For example, the at least first rope pulley and / or the at least second rope pulley has / are partially plastic and partially metal. In this way the weight of the rope pulleys can be reduced so that the forces acting on the water sports train system are reduced. The carrier, and / or the intermediate carrier, and / or the main carrier, and / or the mast can also be formed from a light metal, for example from an aluminum alloy.

According to a further advantageous embodiment of the invention, the at least first rope pulley and / or the at least second rope pulley has side windows which are / are provided on one side or on both sides of the at least first rope pulley and / or the at least second rope pulley, and which are formed to run the rope. The side windows extend outward from the tread at a distance which corresponds at least to the rope diameter. For example, a side shift extends outwards from the tread with a distance which corresponds to twice or three times the rope diameter. The rope has a diameter of 10 mm, for example, and the side windows extend, for. B. 20mm to 30mm from the tread of the rope pulley to the outside. In this way, the rope can be guided in the rope pulleys particularly securely. Furthermore, the side windows can be coated with a material which at least partially has an artificial head. In this way, the resistance of the side windows and thus the pulley can be improved. Furthermore, this design of the side windows significantly reduces the noise development of the entire system. For example, the side windows are coated with PA6, PA66, PA6G, PE-LD, PE-HD, PE-UHMW and / or with various rubber compounds. The base material of the side windows can be, for example, a light metal alloy.

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

The accompanying drawings are intended to provide further understanding of the embodiments of the invention. They illustrate embodiments and, in conjunction with the description, serve to explain principles and concepts of the invention. Other embodiments and many of the advantages mentioned result from the drawings. The elements of the drawings are not necessarily shown to scale with respect to one another. The same reference numerals designate the same or similar components.

Fig. 1 shows a schematic view of a water sports train installation 1 according to an embodiment of the present invention. The water sports train system 1 is designed in particular as a circulating water sports train system which is provided with a rope 10 which forms a loop and thus a round course on a body of water 15. The water sports train system 1 is provided in a body of water 15 and preferably has a plurality of masts 2, between which the rope 10 is stretched and is deflected on the masts 2 in each case. The masts 2 are provided near the bank and extend over the water 15.

Furthermore, a second rope 12, also referred to as an auxiliary rope, is provided, which is coupled to the rope 10, also referred to as the main rope, via drivers 13. By means of devices which can be attached to the rope 10, it is possible to pull a person 14 over the water surface of the water 15. Deflection devices 100 are provided on the masts 2, which are designed to deflect the rope 10 and the rope 12. A respective deflection device 100 has at least one first rope pulley 11 for receiving a first section of the rope 10, and at least one second rope pulley 21 for receiving a second section of the rope 10. The first pulley 11 and the second pulley 21 are rotatably supported in a carrier 30. The carrier 30 is horizontally rotatably supported with respect to the mast 2.

Fig. 2 shows a schematic top view of a deflection device 100 according to an embodiment of the present invention. The deflection device 100 serves to deflect the rope 10 from a first direction R1 into a second direction R2. The deflection device 100 has a first rope pulley 11 for receiving a first section of the rope 10, and at least one second rope pulley 21 for receiving a second section of the rope 10. The first rope pulley 11 and the second rope pulley 21 are in a carrier 30 rotatably mounted. The carrier 30 is horizontally rotatable with respect to a main carrier 40 which is coupled to the mast 2. For this purpose, the deflection device 100 has a joint 50, which is preferably provided in the center of the carrier 30. The joint 50 is in turn connected to the main support 40, which is connected to the mast 2. If, for example, the load on the cable 10 increases, for example by a driver who loads the cable, on the right side of the deflection device 100, it is possible that the right section of the carrier 30 towards the cable 10, which comes from the direction R1 is pivoted, the left portion of the bracket 30 being 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 by a person being pulled over the water 15, particularly well.

By providing such a deflection device 100, it is possible to increase the radius of the curve when deflecting the rope 10 on one of the masts 2 compared to a deflection by means of a single rope sheave. It is therefore possible to deflect the cable 10 more gently and over a longer distance than in comparison with existing systems which have cable pulleys with a constant diameter. Therefore, there are fewer falls and the maintenance costs of the system are reduced.

Since rope pulleys are used instead of rope pulleys, the maintenance of the entire water sports train system is also simplified, since the rope pulleys are reduced in size and weight and are therefore less expensive and easier to handle. In addition, the rope pulleys arranged in a kind of roller rocker enable a continuous contact pressure of the rope pulleys 11 and 21 on the rope 10, thereby preventing the rope 10 from being lifted with respect to the rope pulleys 11 and 21. This increases the operational safety of the system.

In addition, the risk of injury to the operator of the system and / or the people being towed is reduced since the rope pulleys 11 and 21 have a smaller diameter than the rope sheaves. In addition, safety is increased since the rope pulleys 11 and 21 have no spokes in comparison to rope sheaves, which can represent a further risk of injury. Furthermore, the rope 10 is guided by at least two rope pulleys 11 and 21 and is therefore better protected against unwanted derailment.

Fig. 3 shows a schematic top view of a deflection device 100 according to a further embodiment of the present invention. In this embodiment, spring devices 60 and damper devices 70 are provided on the support 30, which are designed to cushion and / or dampen rotation of the support 30 with respect to the main support 40, which is coupled to the mast 2. The main support 40, in which the support 30 is rotatably mounted by means of a joint 50, is directly coupled to the mast 2. The spring devices 60 and the damper devices 70 are articulated to the carrier 30 and to the main carrier 40. This makes it possible to cushion and / or dampen rotation of the support 30 with respect to the main support 40 and the mast 2. In this way, 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 devices 60 and the damper devices 70 can also be between the main support 40 and the mast 2, or between an intermediate support 45 and a main support 40, as shown in FIG Fig. 8 or the Fig. 12 , be provided.

Fig. 4 shows a schematic top view of a deflection device 100 according to a further embodiment of the present invention. In the representation of the Fig. 4 it can be seen that the carrier 30 has a curved shape in this embodiment. The carrier 30 is preferably bent in the direction of the cable 10. In this way, the forces which act on the first pulley 11 and on the second pulley 21 can be absorbed particularly well and transmitted to the main support 40 and to the masts 2.

Fig. 5 shows a schematic sectional view of a rope pulley 11. For example, the rope pulley shown is the first rope pulley 11. The first rope pulley 11 has a sealed bearing 90. The sealed bearing 90 is, for example, a roller bearing, and is sealed such that no further lubrication is necessary and that no foreign bodies or contaminants can penetrate into the interior of the bearing 90. Furthermore, the bearing 90 of the cable pulley 11 is sealed such that no oil or grease can escape from the bearing 90, and e.g. B. can contaminate the water 15. In particular, the bearing 90 is designed such that it can be stored horizontally without the oils and greases being able to escape from the bearing 90.

Furthermore, the cable pulley 11 has a tread 80, which is formed from a friction-increasing and / or noise-reducing material 120. The friction-increasing and / or noise-reducing material 120 can be plastic or rubber, for example. For example, the tread is made of PA6, PA66, PA6G, PE-LD, PE-HD, PE-UHMW and / or different rubber compounds.

Furthermore, the first rope pulley 11 has side disks 110 which are provided on both sides of the first rope pulley 21 and which are designed to guide the rope 10. The diameter 23 of the rope pulley 21 is approximately 30 cm. The rope 10 has a diameter of approximately 10 mm.

The side disks 110 extend outward from the tread 80 at a distance which corresponds at least to the rope diameter. For example, a side window 110 extends from the tread 80 at a distance which is twice or three times the rope diameter. The rope 10 has a diameter of 10 mm, for example, 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 rope 10 can be guided particularly securely in the rope pulleys 11. Furthermore, the side windows 110 can 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, this design of the side windows significantly reduces the noise development of the entire system. For example, the side windows 110 are coated with PA6, PA66, PA6G, PE-LD, PE-HD, PE-UHMW and / or with various rubber compounds. The base material of the side windows 110 can be a light metal alloy, for example.
