An exemplary embodiment of the device according to the invention provides a device for producing a stationary wave, as described in particular in detail above. Preferably, the device has a wave pool in which an obstacle is disposed. In addition, in the wave pool is arranged a ramp which is connected contiguously to the obstacle at an interface. A water pressure is created in a compartment and water is conducted on the ramp through the evacuation device. Furthermore, the device comprises downstream of the wave basin in the flow direction therein a retaining device which serves to protect the users against the risk of being expelled from the device. The retainer is inclined upward in the direction of flow so as to allow easy exit of the device, including the wave pool. The retainer has a plurality of cavities and is configured in particular as a perforated plate or grid so that water flowing into the wave pool can be discharged into the body of water surrounding the device. walk. The retainer forms an angle with the bottom of the wave pool. The restraint is associated with a trampoline, preferably downstream in the flow direction in the wave pool, which allows easy entry and exit of the device. The trampoline includes

in particular a perforated flexible mat. The trampoline is disposed substantially parallel to the bottom of the wave pool. Furthermore, the device comprises at least one and preferably two means of flotation by means of which the device can float like a pontoon in a body of water. The flotation means are substantially hollow and filled with air. The device also has at least one bridge which is disposed at least partially around the wave pool and the compartment on the device. This gateway allows people to park on the device, to move safely on the device and / or to observe the users of the device. Furthermore, the device has on the flotation means paths which are in particular coated with EVAC foam. These paths allow users to access the stationary wave. The flotation means also constitute the side walls of the wave pool. In the compartment are arranged at least one, preferably two, more

preferably three, still more preferably four and even more preferably five or more pumps. The at least one pump draws water from the surrounding body of water and discharges it into the compartment. The water is driven on the ramp. Through the obstacle is produced a stationary wave that can be used by users of the device to surf. Water flows through the restraining device and the trampoline to join the surrounding body of water.

To prevent objects, animals or persons from being sucked in, a safety device is preferably provided which is arranged upstream of the pump in the suction direction. The pump is arranged horizontally, which makes it possible to obtain a very compact structure in the vertical axis of the device. An appropriate arrangement of the flotation means allows the device used as a pontoon to float freely in the body of water even if it has a shallow depth. Behind the retainer is the trampoline, the depth of the device being approximately adjustable so that the water level is approximately the height of the trampoline. A user of the stationary wave falling for example by surfing is carried in the direction of flow of the wave basin to the retainer. If the user does not regain his balance, he is collected by the restraint and placed on the soft trampoline, which prevents injury. The device preferably floats as a pontoon in the body of water by the flotation means so that at least parts of the device are above the water level and the device floats above the water. bottom of the body of water without touching it. If not, it can also touch the bottom and be placed on it. The important thing then is only that the water passing through the intake of water can be sucked by the at least one pump.

The at least one pump is disposed in a pumping space of the compartment. Preferably, five pumps are provided in the device. Upstream of the pumping space is a safety space which contains a safety device through which the influx of water is conducted and which prevents solids from entering the compartment. The water sucked by the pump is driven out of the pumping space and joins the evacuation device through the intermediate space. The evacuation device is directly adjacent to the ramp and conducts the water thereon, in particular by a typing flow. At the interface, the ramp is adjacent to the obstacle. In the exemplary embodiment, the slopes of the ramp and the obstacle at the interface are substantially equivalent. The water that is driven by the ramp accumulates behind the obstacle to form a stationary wave. In one embodiment, the bottom or floor of the wave pool terminates at the location where the restraint is located. In this embodiment, no discharge device is provided. Water can escape from the device immediately behind the wave pool or behind the end of the bottom or floor of the downstream wave pool, through the restraint in the flow direction and downward. The level of the surrounding water body is then preferably slightly above the trampoline and the bridge or adapted to the depth of the device.

In another embodiment of the device, the latter has a downstream delineation of the wave basin by a discharge device which regulates the evacuation of water from the wave basin. The delivery device has a retaining wall in which is an evacuation. In the evacuation is disposed a valve with which the evacuation of water, and thus the hydraulic jump in the wave pool, can be controlled or adjusted. A retainer may then be disposed at least partially, and preferably entirely, in the wave pool.

In another embodiment of the device, the wave pool comprises the retainer, that is, the bottom of the wave pool extends partially under the retainer. This other embodiment is independent of the water level or the depth of the device. In this other embodiment, the device can float in the body of water so that the wave pool, preferably the obstacle and more preferably the water outlet of the compartment are at least partially above the water level.

The device has for example a bridge which is located above the water level. This gateway can be used, for example, to jump into the body of water. Preferably, the flotation means comprise paths that allow the users of the device to enter the stationary wave, in particular at its deepest point. The paths and the deepest part of the wave are located below the water level.

The flotation means preferably have intermediate walls which on the one hand provide protection against sinking in the event that parts of the flotation means are damaged. Furthermore, the intermediate walls a submersion or partial filling of the flotation means, for example with water, to orient the device substantially horizontally in the water or to counter the heel or the plate of the device. Between the flotation means is the safety space which is delimited by the safety device.

Because intermediate walls are arranged in the at least one flotation means, in the event of leakage in the flotation means, only one section of the flotation means Flotation would fill with water and the complete device would not sink. Furthermore, the intermediate walls stabilize the flotation means. In one embodiment, it is further provided that the sections of the buoyancy means may be filled, including water, at least partially independently of each other to counter the heel and trim. A power supply is disposed in the flotation means. This power supply comprises a generator with which at least the at least one pump can be actuated. Preferably, electrical power supplies are arranged in the two flotation means of the device. The means of flotation and the

compartment preferably have the same depth.

The flotation means and the compartment, as well as the safety space, preferably have the same depth. The safety space is divided into sections, one section being provided for each pump. The safety device is also preferably divided into sections in order to be able to easily maintain each pump.

Fig. 7 perspective view from below the device according to Fig.1. Fig. 1 shows in a first embodiment a device 10 for producing a stationary wave 32 which is shown p. ex. in FIG. 2. The device 10 has a wave pool 12 in which an obstacle 14 is disposed. Furthermore, in the wave pool 12 is disposed a ramp 16 which is connected contiguously to the obstacle 14 at an interface 18. A water pressure is created in a compartment 20 and water is conducted on the ramp 16 through the exhaust device 48 which can be seen in FIG. 3. Furthermore, the device 10 comprises a retaining device 22 which serves to protect the users against the risk of being expelled from the device. The retaining device 22 is inclined upwards in the direction of flow 1 3 so as to allow easy exit of the device 10. The retaining device 22 is disposed downstream, in the flow direction 1 3, of the basin 12. It has a plurality of cavities and is configured in particular as a perforated plate, so that the water flowing into the wave pool 12 can be discharged into the body of water surrounding the device 10. walk. Water flows into the retainer 22 through the openings. The retaining device 22 is associated with a trampoline 24 which makes it easy to enter and exit the device. The trampoline 24 includes a perforated flexible mat. Furthermore, the device 10 comprises two flotation means 26 by means of which the device 10 can float like a pontoon in a body of water. The flotation means 26 are substantially hollow and at least partially filled with air. The two flotation means 26 are spaced and arranged parallel to each other in the longitudinal direction of the device 10 and form the lateral limits of the wave pool 12. The device 10 also has a bridge 28 which is arranged partially around the wave pool 12 and the compartment 20 on the device 10. This bridge 28 allows people to park on the device 10, to move safely on the device 10 and / or observe the users of the device 10 surfing. Furthermore, the device 10 has on the flotation means 26 paths 30 which are in particular coated with EVAC foam. These paths 30 allow users access to the stationary wave 32. The flotation means 26 further constitute the sidewalls 17 of the wave pool 12. FIG. 2 shows a perspective view of the device 10 in longitudinal section. It will be noted that at least two pumps 34.1 and 34.2 are arranged in the compartment 20. The pumps 34.1 and 34.2 draw water from the surrounding water body 40, whose level is indicated by a line, and reject it in the compartment 20. The water is conducted on the ramp 16. With the obstacle 14 is produced a stationary wave 32 which can be used by the users of the device 10 for surfing. Water flows through the retainer 22 and the trampoline 24 to join the surrounding body of water.

It can also be seen in FIG. 2, to prevent objects, animals or persons from being sucked in, there is provided a safety device 36 in the form of a grid which is arranged upstream of the pumps 34.1 and 34.2 in the suction direction 35 and therefore upstream 20. In addition, it can be seen in FIG. 2 the bottom 38 of the body of water represented by a line. It can be seen further that the pumps 34.1 and 34.2 are arranged horizontally, which makes it possible to obtain a very compact structure in the vertical axis 37 of the device 10. An appropriate arrangement of the flotation means 26 allows the device 10 used as a pontoon to float freely in the body of water even if it has a shallow depth.

Moreover, it can be seen in FIG. 2 that behind the retaining device 22 is disposed the trampoline 24 and that the level of the water 40 is approximately at the height of the trampoline 24. A user of the stationary wave 32 which falls for example by surfing is carried in the flow direction 1 3 of the wave basin 12 to the retaining device 22. If the user has not found its balance, it is gently collected by the retainer 22 and deposited on the trampoline flexible 24, which prevents any injury.

Fig. 3 shows a longitudinal section through the device 10. The device 10 floats like a pontoon over the bottom 38 of a body of water by the flotation means 26 so that at least parts of the device 10 are located. above the water level 40. In FIG. 3, the compartment 20 can be seen in detail, with a pump 34 disposed in a pumping space 44. As can be seen for example in FIG. 5, five pumps 34.1, 34.2, 34.3, 34.4 and 34.5 are provided in the device 10. Upstream of the pumping space 44 and thus the compartment 20 is a security space 42 which contains the security device 36 through which is led the inflow of water and which prevents solids reach the compartment 20. The water sucked inter alia by the pump 34 is driven out of the pumping space 44 and joined an evacuation device 48 through an intermediate space 46. The evacuation device 48 is directly adjacent with the ramp 1 6 and leads the water thereon, in particular by a striking flow. At the interface 18, the ramp 16 is adjacent to the obstacle 14. In the embodiment shown, the slopes of the ramp 1 6 and the obstacle 14 at the interface 18 are substantially equivalent. The water which is driven by the ramp 14 accumulates behind the obstacle 14 to form a stationary wave 32.

On the longitudinal section of FIG. 3, it can further be seen that the bottom 1 of the wave basin 1 2 terminates at the location where the retainer 22 is located. The water can escape from the device 10 immediately behind the wave pool 1 2 or behind the bottom end 15 of the downstream wave basin, through the retainer 22 in the flow direction 1 3 and down. In FIG. 3, it can also be seen that the level 40 of the surrounding body of water is slightly above the trampoline 24 and the bridge 28 or adapted to the depth of the device 10. Fig. 4 shows a longitudinal section through a second embodiment of the device 10. Unlike the first embodiment according to FIGS. 1 to 3, it has downstream of the wave pool 12 a discharge device 23 which regulates a water discharge from the wave pool 1 2. The discharge device 23 has a retaining wall 25 and an evacuation 27 which lies on it. The retaining wall 25 delimits the downstream wave basin in the direction of flow. For the sake of clarity, it is not shown that in the discharge 27 is disposed a valve with which the water discharge, and thus the hydraulic jump in the wave pool, can be controlled or adjusted. It can also be provided several evacuations 27, each evacuation 27 preferably having a valve. In FIG. 4, it can further be seen that a retaining device 22 can be entirely disposed in the wave pool 12, the bottom of the wave pool 1 5 extending under the retaining device 22.

This embodiment is independent of the level of the water extent 40. In the second embodiment shown, the device 10 can float in the water so that the wave pool 1 2, preferably the obstacle 14 and more preferably evacuation 27 are located at least partially above the level of the body of water 40.

Fig. 5 shows a cross section of the device 10 according to FIG. 1 in a perspective view. This view is taken approximately in the direction of the compartment 20. It will be noted that the device has a bridge 28 which is disposed above the level of the expanse of water 40. The bridge 28 can be used for example to jump in the expanse of water. Moreover, it can be seen in FIG. 5 that on the two flotation means 26 are formed paths 30 which allow the user of the device 10 to enter the stationary wave 32, especially at the deepest point. The paths 30 and the deepest part of the wave 32 are located below the level of the body of water 40. The arrangement of the five pumps 34.1, 34.2, 34.3, 34.4 and 34.5 is also clearly visible on Fig.5. In accordance with the number of pumps 34, the security space 42 is divided into five sections. This division can be done p. ex. using intermediate walls that are watertight. In general, the security space 42 can be divided in the sense of the present invention, preferably depending on the number of pumps 34 provided. If, p. For example, three pumps 34 are provided, the clearance 42 is divided into three sections. The division is preferably using watertight walls. In FIG. 5, it can be seen further that the flotation means 26 have intermediate walls 50 which provide protection against sinking in the event that parts of the flotation means 26 are damaged. Furthermore, the intermediate walls 50 allow submersion or partial filling of the flotation means with water to orient the device 10 substantially horizontally in the body of water or to counter the heel or attitude of the device 10. In FIG. 5, it can be seen further that between the flotation means 26 is the security space 42 which is delimited by the security device 36, which is a generally preferred embodiment of the device 10 according to the invention. Fig. 6 shows the device 10 in a perspective view with a section through a flotation means 26. It can be seen that intermediate walls 50 are arranged in the flotation means 26. In case of leakage in the flotation means 26, a only section of flotation means 26.1, 26.2 or 26.3 would fill, and the device 10 would not flow completely. Furthermore, the intermediate walls 50 stabilize the flotation means 26. In an embodiment not shown here, it is furthermore provided that the sections of means of flotation 26.1, 26.2 and 26.3 can be filled, in particular with water, at least partially independently of each other to counter the bed and the plate. In the embodiment shown in FIG. 6, it is indicated a power supply 52 which is disposed in the flotation means 26. This power supply 52 comprises a generator with which at least the pumps 34 can be actuated. Preferably, electrical power supplies 52 are arranged in the two flotation means 26 of the device 10. Furthermore, it can be seen in FIG. 6 that the flotation means 26 and the compartment 20 have the same depth. It can also be seen in FIG. 6 the bridge 28, the path 30 on the flotation means 26, the wave pool 12 and the retaining device 22 and the trampoline 24. Fig. 7 shows the device 10 from below. It can be seen in this view that the flotation means 26 and the compartment 20, as well as the security space 42, have the same depth. It can also be seen that the security space 42 is divided into sections, one section being in particular provided for each pump 34. In the embodiment shown, the security device 36 is also divided into sections in order to be able to easily maintain each pump.

It can also be seen in FIG. 7 that the retainer 22 is disposed at an angle 23 relative to the floor or the bottom of the wave zone 15. Furthermore, it can be seen in FIG. 7 the trampoline 24 and a part of the peripheral bridge 28.

The proposed invention allows surfing in any body of water, including stagnant. The device for producing a stationary wave that can be used as a pontoon is a particularly environmentally friendly and mobile water sports facility.
