Definitions
- the present invention relates to a device and a method for artificially recreating the practice of a water sports gliding.
- An object of the invention is to propose a solution that makes it possible to increase the width of the practice area, without necessarily increasing the energy consumption to deliver the water flow.
- Another aim is to propose a solution that allows evolutions and varied figures of style in the practice of the chosen sport (s).
- Another goal is to propose a solution that allows progress in this sport (s), without necessarily changing the practice area.
- Another goal is to propose a solution that achieves all or some of the above goals, without necessarily increasing the size, therefore the size, of the device.
- Another aim is to satisfy a variety of water sports, especially water skiing, wake-skateboarding, wake-boarding, kite-surfing, surfing which is practiced on at least one board. .
- a proposed solution to all or part of these aims is indicated in claim 1.
- water flow and detection means will allow only a portion of the support, and therefore the practice area, waterable by the flow of water out of the water flow means is sprayed with a water way allowing the practitioner to evolve there.
- FIG. 1 is an external schematic perspective of the device of the invention
- FIG. 2 is a schematic top view of a possible embodiment
- FIG. 3 is an internal schematic side view
- FIG. 4 (FIGS. 4a, 4b, 4c) shows successive states of operation in one and the same practice zone
- FIGS. 5, 6 show a possible embodiment of two contiguous valves
- FIGS. 7,8 (FIGS. 7a, 7b, 7c, 8a, 8b, 8c) show other operations, according to two possibilities
- FIG. 9 illustrates a jump zone
- FIG. 10 schematizes a solution for detecting the presence of the user at the end of the cable that he can hold
- FIGS. 11, 12, 13 show two other possible positions of the detectors
- FIG. 1 shows a practitioner 1 evolving on a stream of water 3 created by a device 5.
- the device 5 comprises means 7 for the flow of water, and means 11 for servocontrol in position to ensure a distribution, on the support 9, of the flow of water created, depending on the position, or displacements on this support, the user or mobile means with him, such as his ski board (see Figures 1, 2, 3) or the cable 2.
- these servo-control means 11 comprise detection means, such as 13al, 13a2, 13bl, 13b2 ... (FIGS. 2, 4) for detecting the position, or displacements, of the user 1, or of his board the, during his / their movements on the support 9, and act accordingly on the water flow means 7.
- the practitioner 1 will thus be able to evolve at will on a body of water whose position will evolve with his or her board.
- Figures 1, 2 this practitioner is held by a cable (or a rope) 2, one end of which is fixed to a mast 4, here fixed, disposed on the side from which the flow of water 3. It can evolve for example following the arc 6 of FIG. He stands facing the flow or side (bends ..), without leaving with him.
- the detection means such as 13al, 13a2, 13bl, 13b2 ... will be favorably adapted to detect limit movements of the user or his board la, laterally with respect to the direction 15 of the water flow on the support (see figures 1, 2, 4).
- the water flow means 7 comprise water distribution means 17 adapted to form a series of water outlet mouths such as 17a, 17b through all or part of which flow water passes to the (above) support 9 which is arranged horizontally (level).
- the flow rate and the pressure of the water expelled by the mouths 17a, 17b ... concerned will be adapted to provide the skier 1 the desired lift, by sending under him a carpet of water to a speed and a variable thickness.
- the speed between the water and skier standards will be respected.
- the outlets of water, such 17a ..., are carried by a frame 19 enclosing a collector box 19a adapted to the circulation of water (Figure 6).
- This box rises above the level of the support 9 (see Figures 1, 3) and extends here perpendicularly to the direction 15 of the water flow.
- the frame 19 here carries the mast 4 which stands above it.
- the means 7 for the flow of water advantageously comprise, FIG. 2, a line 21 of mobile hatches, such as 23a, 23b, FIG. 5, connected to the servo-control means 11 and arranged facing the line of mouths that they cover or discover in order to to control the water outlets towards the support 9.
- Each trapdoor width LJ 1 is controlled by the servo-control means 11, via a jack, such as 24a or 24b in FIG. 6.
- the cylinders will be moved vertically vertically and controlled in all or nothing. Their stroke is guided on the sides by guiding elements (such as 26a, 26b) fixed on the frame 19.
- Figure 6 still, we see an illustrated portion of the box 19a which here feeds the mouths 17a, 17b of preferably rectangular shape, thereby delivering the water in a substantially rectangular output flow.
- the front wall of the box 19a is doubled by a sliding partition provided with one or more mouths (openings) and moving along this wall by opening and closing in front of some of the mouths of the box, a water outlet coming into being each time a mouth of the box coincides with a mouth of the partition.
- the flow means 7 will generally comprise water distribution means adapted to form a series of outlets. mouths of water outlet through all or part of which the flow of water can pass to the support 9, these mouths being adapted to open and close under the control of the aforementioned detection means, such as 13al, 13a2 , 13bl, 13b2 ....
- the water flow means 7 will thus comprise means (17a, 17b ... 23a, 23b ... 25 ...) for modifying the height, the width and the speed of the water flow created on the support.
- the detection means will be favorably distributed in several places, along at least one line transverse to the direction of each stream of water created and along the areas of the support where these flows can be created. 2, it can be seen that the schematized detection means are arranged along two lines 27a, 27b parallel to one another and to the line 21 of the mouths of FIG. water outlet, therefore perpendicular to the general direction 15 of the water flow / streams generated on the practice support 9.
- the detection means such as 13al, 13a2, 13bl, 13b2 ... comprise a series of beam detectors and that here the opening and closing of each mouth, such as 17a, 17b, is controlled by a pair of these detectors disposed on either side of the mouth concerned, except towards the lateral ends of the support where the first and last mouths of the series are respectively controlled by first and last detectors of said series located towards these ends; here: 13aO / 13bO on the left and 13ai / 13bi on the right. It is advised that the detection means comprise optical (beam) sensors.
- the support 9 will advantageously include a flexible underlying mat, 29 .
- this carpet will be stretched by tensioning means 31, such as a weight pulling a flexible resistant fabric.
- the support 9 and each layer of water 28 are surrounded by protective beads.
- the box 19a and the net 33 extend a support structure 37 of the device containing means 39 for recirculation / recycling water.
- These means 39 comprise one or more ducts open upwards at the rear, here under the net 33, to allow the flow of water 28 to flow therethrough, beyond the rear edge 9a of the support 9.
- one or more pumps 41 suck the water from the conduits and pressurized it back into the water supply box 19a of the mouths 17a, 17b ...
- Anchoring means 43 can hold the entire device 1 on the ground.
- the solution of the invention makes it possible to reduce the height and the width of the flow of water to be supplied to guarantee the lift, quantities which size the flow rate.
- the solution of the invention makes it possible to offer a practically limitless practice area for the same quantity of water dispensed; its width size (L_, Figures 1, 2) is completely flexible. It also makes it possible to adapt the water mat 3 according to the level of the user; width, thickness and flow velocity are controlled.
- the detection system will therefore advantageously comprise a set of optical lines each defined by a transceiver duo, such as 13a0, 13b0... 13a, 13b1.
- the detections are performed each time the user (or his board) cut an optical line.
- the signals addressed by these sensors control the hatches 23a ... via a programmable controller 45 belonging to the control means 11.
- the width L4 of the stream created could be different (a priori lower) than the distance between two such successive optical lines.
- an optical line is actually formed by two duos of adjacent sensor-receivers, such as 13all, 13bl1; 13al2, 13bl2.
- This duo forming two consecutive beams, makes it possible to know in which direction the user moves, that is to say on which side it is located with respect to the optical line and therefore between which optical doors it is present.
- Each valve mouth-trap
- the optical gate of the valve 17a / 23a is formed by the double detector optical lines 13a1, 13bl1; 13al2, 13bl2 and 13al3, 13b13; 13al4, 13bl4.
- the optical door of the mouth 17c is formed only by the double optical line Lo9, Lo10 since it has here been assumed that, skier to practice, three successive valves are always open and the other closed.
- the shaded area marks the localized water flow, the arrows the three open valves according to the practitioner's position.
- FIG. 8 FIG. 8 (FIGS. 8a, 8b, 8c)
- another way of implementing the servocontrol would be to open the hatches on each side and opposite (if necessary) of the last cut optical line.
- a single cut optical line corresponds a configuration of opening and closing traps.
- the optical lines such as Loi, Lo3 are placed in the middle of each valve (mouth + trap), except those of the ends. It can be seen that when the user has last cut the line Loi, the first three traps to the right of Fig. ⁇ a are open (arrows) and the other closed. Similarly, when the user has last cut line Lo3 ( Figure 8c), the hatches 23a, 23b, 23c are open, the other closed.
- each mouth are controlled by (at least) a detector activated by the cutting of its beam by the user or his board. Beams other than optical may be suitable.
- the device can be assigned different other detection systems, such as sensors falling the position of the rope 2 which moves with the user, or a corner sensor, for example positioned on the d anchoring rope 2 and raising its angle with respect to an original position. This indirectly gives the position of the user. It is also possible to detect the string using the same detection principle as the example of the optical line, thanks to a detection frame 100 through which the string passes and which includes several sensors 101a, 103a, 101b, 103b ... defining a series of lines 110, 112 ... detection, here vertical.
- detection frame 100 through which the string passes and which includes several sensors 101a, 103a, 101b, 103b ... defining a series of lines 110, 112 ... detection, here vertical.
- the device according to the invention could also include a structure 47 in elevation to define a jump surface on which the user could evolve.
- the device includes the following system, it being specified that it could be used alone, not necessarily in the context of the scope of the attached independent claim (s).
- These servo means will then be suitable for controlling the water flow means 7 to adapt the presence of this water and / or its distribution on the support.
- the user can be detected as absent at the end of the chord 2.
- the new information translated by the controller will change the servo mode of the detection system described above.
- the device will then be able (depending on the programming retained servo means) for example either completely interrupt the flow, or significantly reduce, or distribute it differently, especially in away from the drop zone, then no longer watering the area around the user.
- a voltage sensor may in particular be suitable for detecting the tension in the cable.
- Figure 10 schematizes this.
- the presence or absence of the user will be detected at the end of the cable 2 to which he is supposed to stand to practice, and the means will be controlled. flow 7 so that they supply or not water the support, accordingly.
- the operation of the device can be likened to all or nothing: if the user is detected in a gliding situation, the servo propels the water flow 3 under it on the belt 9, depending on its position. If the user 1 is detected as in a non-slip situation, the water is no longer propelled onto the carpet but directly sent into the recovery tank 39a (see FIGS. A suitable means, here a hatch 125, drops the water and prevents it from reaching the carpet. Thus, if the user falls, he drops the rope 2 and the device cuts off any water supply on the gliding mat 9, without interrupting the operation of the water pump 41. And the user is not embarrassed to to get up.
