An exemplary embodiment of the device according to the invention provides a device for producing a standing wave, as described in particular in detail above. Of preferably, the device has a wave basin in which an obstacle is placed. Furthermore, in the wave basin is arranged a ramp which is joined in a contiguous manner to the obstacle at an interface. Water pressure is created in a compartment and water is conducted on the ramp through the discharge device. Further, the device comprises downstream of the wave basin in the direction of flow therein a retainer which serves to protect the users against the risk of being thrown from the device. The retainer is tilted upward in the direction of flow so as to allow easy exit from the device, especially from the wave basin. The retainer has a plurality of cavities and is particularly configured as a perforated sheet or a grid, so that the water flowing in the wave basin can be discharged into the body of water surrounding the device by market. The retainer forms an angle with the bottom of the wave basin. Associated with the retainer is a trampoline, preferably downstream in the direction of flow in the wave pool, which allows easy entry and exit of the device. The trampoline comprises in particular a perforated flexible mat. The trampoline is placed substantially parallel to the bottom of the wave pool. Furthermore, the device comprises at least one and preferably two flotation means 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 walkway which is disposed at least partially around the wave basin 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 paths on the flotation means which are in particular coated with EVAC foam. These paths allow users to access the standing wave. The flotation means further constitute the side walls of the wave basin.

In the compartment are disposed 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 sucks water from the surrounding body of water and rejects in the compartment. The water is conducted on the ramp. Thanks to the obstacle, a standing wave is produced which can be used by users of the device for surfing. Water flows through the retainer and trampoline to join the surrounding body of water.

To prevent objects, animals or people 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 the latter 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 at the height of the trampoline. A user of the standing wave which falls, for example while surfing, is carried away in the direction of flow from the wave basin to the retainer. If the user has not regained their balance, they are picked up by the restraint and placed on the flexible trampoline, which helps prevent injury.

The device preferably floats like a pontoon in the body of water thanks to the flotation means so that at least parts of the device are above the water level and the device floats above the water level. bottom of the body of water without touching it. Otherwise, it can also touch bottom and be landed on top of it. The important thing then is only that the water passing through the water inlet 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 from the pumping space is a safety space which contains a safety device through which the inflow of water is conducted and which prevents solids from entering the compartment. The water sucked in by the pump is led out of the pumping space and joins the evacuation device through the intermediate space. The discharge device is directly adjacent to the ramp and conducts the water thereon, in particular by a knock 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 collects behind the obstacle to form a standing wave.

In one embodiment, the bottom or floor of the wave basin terminates where the retainer is located. In this embodiment, there is no delivery device. Water may drain from the device immediately behind the wave pool or behind the end of the bottom or floor of the wave pool located downstream, through the retainer in the direction of flow and down. The level of the surrounding body of water is then preferably slightly above the trampoline and the gangway or adapted to the depth of the device.

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

In another embodiment of the device, the wave basin includes the retainer, in other words, the bottom of the wave basin extends partially below the retainer. This other embodiment is independent of the water level or the depth of the device. In this further embodiment, the device can float in the body of water such that the wave pool, preferably the obstacle and more preferably the water outlet of the compartment are at least partially located at- above water level.

The device has for example a walkway which is located above the water level. This walkway can be used, for example, to jump into the body of water. Paths are preferably formed on the flotation means which allow users of the device to enter the standing wave, in particular at its deepest place. The paths and the deepest place of the wave are located below the water level.

The flotation means preferably have intermediate walls which on the one hand constitute protection against sinking in the event that parts of the flotation means are damaged. Furthermore, the intermediate walls submerge or partially fill the flotation means, for example with water, to orient the device substantially horizontally in the water or to counter the list or the trim of the device. Between the flotation means is the safety space which is delimited by the safety device.

Because intermediate walls are provided in the at least one flotation means, in the event of a leak in the flotation means, only one section of the flotation means would fill with water and the entire device would not sink. Furthermore, the intermediate walls stabilize the flotation means. In one embodiment, it is further provided that the sections of the flotation means can be filled, in particular with water, at least partially independently of one another in order to counter the list and the 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, power supplies are arranged in the two flotation means of the device. The flotation means and the compartment preferably have the same depth.

The Fig. 1 shows in a first embodiment a device 10 for producing a standing wave 32 which is shown on p. ex. on the Fig. 2 . The device 10 has a wave pool 12 in which an obstacle 14 is disposed. Furthermore, in the wave pool 12 a ramp 16 is arranged which is joined in a contiguous manner 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 device 48 that can be seen on the Fig. 3 . Further, the device 10 includes a retainer 22 which serves to protect users against the risk of being kicked out of the device. The retainer 22 is inclined upward in the direction of flow 13 so as to allow easy exit from the device 10. The retainer 22 is disposed downstream, in the direction of flow 13, of the wave basin. 12. It has a plurality of cavities and is configured in particular as a perforated sheet, so that the water flowing in the wave basin 12 can be discharged into the body of water surrounding the device 10 in operation. Water flows into retainer 22 through the openings. The retainer 22 is associated with a trampoline 24 which allows easy entry and exit of the device. The trampoline 24 notably comprises 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 apart and arranged parallel to each other in the longitudinal direction of the device 10 and form the lateral limits of the wave basin 12. The device 10 also has a walkway 28 which is partially disposed around the wave basin 12 and of the compartment 20 on the device 10. This gateway 28 allows people to park on the device 10, to move in complete safety on the device 10 and / or to observe the users of the device 10 while 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 to access the standing wave 32. The flotation means 26 further constitute the side walls 17 of the wave basin 12.

The 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 suck water from the surrounding body of water 40, whose level is indicated by a line, and discharges it into the compartment 20. The water is conducted on the ramp 16. Thanks to the obstacle 14, a standing wave 32 is produced which can be used by the users of the device 10 for surfing. Water flows through retainer 22 and trampoline 24 to join the surrounding body of water.

We can also see on the Fig. 2 that, in order to prevent objects, animals or people from being sucked in, a safety device 36 in the form of a grid is provided which is arranged upstream of the pumps 34.1 and 34.2 in the suction direction 35 and therefore upstream of the compartment 20. In addition, one can see on the Fig. 2 the bottom 38 of the body of water which is represented by a line. It can also be seen 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. A suitable arrangement of the flotation means 26 allows the device 10 to be used as a pontoon. float freely in the body of water even if it is shallow.

Moreover, one can see on the Fig. 2 that behind the retainer 22 is the trampoline 24 and that the water level 40 is approximately at the height of the trampoline 24. A user of the standing wave 32 who falls for example while surfing is carried away in the direction of flow 13 from the wave pool 12 to the retainer 22. If the user has not regained his balance, he is gently collected by the retainer 22 and deposited on the flexible trampoline 24, which allows avoid injury.

The Fig. 3 shows a longitudinal section through the device 10. The device 10 floats like a pontoon above the bottom 38 of a body of water by means of the flotation means 26 so that at least parts of the device 10 are at the bottom. above water level 40. On the 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 on the figure. 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 therefore of the compartment 20 is a safety space 42 which contains the safety device 36 through which the flow of water is conducted and which prevents solids from entering the compartment 20. The water sucked in by the pump 34 among others is conducted out of the pumping space 44 and joins an evacuation device 48 through an intermediate space 46. The evacuation device 48 is directly adjacent to the ramp 16 and conducts water thereon, in particular by a striking flow. At interface 18, ramp 16 is adjacent to obstacle 14. In the embodiment shown, the slopes of ramp 16 and of obstacle 14 at interface 18 are substantially equivalent. The water which is conducted by the ramp 14 collects behind the obstacle 14 to form a standing wave 32.

On the longitudinal section of the Fig. 3 , it can further be seen that the bottom 15 of the wave basin 12 ends where the retainer 22 is located. Water can drain from device 10 immediately behind wave tank 12 or behind the bottom end 15 of the downstream wave tank, through retainer 22 in the flow direction 13 and downstream. low. On the Fig. 3 , we can also see that the level 40 of the surrounding body of water is slightly above the trampoline 24 and the walkway 28 or adapted to the depth of the device 10.

The Fig. 4 shows a longitudinal section through a second embodiment of the device 10. Unlike the first embodiment according to Fig. 1 to 3 , the latter has downstream of the wave basin 12 a discharge device 23 which regulates a discharge of water from the wave basin 12. The discharge device 23 has a retaining wall 25 and an outlet 27 which is located above. The retaining wall 25 defines the wave basin downstream in the direction of flow. For the sake of clarity, it is not shown that in the drain 27 is disposed a valve with which the water discharge, and therefore the hydraulic jump in the wave basin, can be controlled or regulated. Several outlets 27 can also be provided, each outlet 27 preferably having a valve. On the Fig. 4 , it can also be seen that a retaining device 22 can be disposed entirely, in the wave basin 12, the bottom of the wave basin 15 extending under the retaining device 22.

This embodiment is independent of the level of the body of water 40. In the second embodiment shown, the device 10 can float in the water so that the wave pool 12, preferably the obstacle 14 and more preferably the drain 27 are located at least partially above the level of the body of water 40.

The 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 walkway 28 which is arranged above the level of the body of water 40. The walkway 28 can be used, for example, to jump into the stretch. of water. Moreover, one can see on the Fig. 5 that on the two flotation means 26 are formed paths 30 which allow the user of the device 10 to enter the standing wave 32, in particular at the deepest place. Paths 30 as well as the deepest point of wave 32 are located below the level of 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 the Fig. 5 . In accordance with the number of pumps 34, the safety space 42 is divided into five sections. This division can be done on p. ex. using intermediate walls which are watertight. In general, the safety space 42 can be divided within the meaning of the present invention, preferably according to the number of pumps 34 provided. If, p. eg, three pumps 34 are provided, the safety space 42 is divided into three sections. The division is preferably carried out using watertight walls.

On the Fig. 5 , it can also be seen that the flotation means 26 have intermediate walls 50 which constitute 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 list or the attitude of the device 10. On the Fig. 5 , we can also see that between the flotation means 26 is the safety space 42 which is delimited by the safety device 36, which is a generally preferred embodiment of the device 10 according to the invention.

The 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 disposed in the flotation means 26. In the event of a leak in the flotation means 26, only one flotation medium section 26.1, 26.2 or 26.3 would fill, and device 10 would not sink completely. Furthermore, the intermediate walls 50 stabilize the flotation means 26. In an embodiment not shown here, it is further provided that the flotation means sections 26.1, 26.2 and 26.3 can be filled, in particular with water, at less partially independently of each other in order to counter heel and trim. In the embodiment shown in Fig. 6 , there 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 operated. Preferably, power supplies 52 are arranged in the two flotation means 26 of the device 10. Furthermore, one can see on the Fig. 6 that the flotation means 26 and the compartment 20 have the same depth. We can also see on the Fig. 6 the gangway 28, the path 30 on the flotation means 26, the wave basin 12 as well as the retainer 22 and the trampoline 24.

The Fig. 7 shows device 10 from below. It can be seen in this view that the flotation means 26 and the compartment 20, as well as the safety space 42, have the same depth. It can also be seen that the safety space 42 is divided into sections, one section being in particular provided for each pump 34. In the embodiment shown, the safety device 36 is also divided into sections in order in particular to be able to easily maintain each pump. pump.

We can also see on the Fig. 7 that the retaining device 22 is arranged at an angle 23 with respect to the floor or to the bottom of the wave zone 15. Moreover, one can see on the Fig. 7 the trampoline 24 and part of the peripheral walkway 28. The proposed invention makes it possible to surf in any body of water, including stagnant. The device for producing a standing wave which can be used as a pontoon constitutes a particularly environmentally friendly and mobile water sports facility.
