These trips can be made at the speed and / or the desired torque.
• a first embodiment is described with reference to FIG. 1. It comprises in particular fixed points 1, for example on earth 12, a return pulley 2, two coils 4 actuated by a motor 5 and a rope forming a segment 3 on each side of the pulley 2, each segment 3 being wound on a 4.
• the or the motors are controlled by a controller or controller 6.
• the user 10 in this case a follower of water skiing is towed on the water 1 1 by the segment 3
• the establishment of the device according to the invention is very simple: the device (for example in the form of a frame 20 and including in particular the coils 4, motor 5 and controller 6 is strapped by a strap V or anchored to a fixed point 1 (for example a tree or a mast or other equivalent fixed point) and the return pulley 2 is fixed in the same way, at the other end of the segment 3, for example by using a strap 1 'attached to a fixed point 1. the pulley 2 the user 10 unrolls a rope from two coils 4 thus creating a segment 3.
• a fixed point 1 for example a tree or a mast or other equivalent fixed point
• the device can drive the user 10 or an object along the segment 3, in both directions and with the same force.
• the user 10 himself can pilot the device in speed and co uple if desired by means of a remote control.

• the device according to the invention eliminates any installation fixed, of any bank or any intermediate ground contact between the two anchor points 1. It allows a rapid deployment of the system and makes it easily transportable, for example in a car trunk or on a trailer. It allows to divide the costs of practice of these disciplines (ski or water ski) because only the energy to tow the user 10 or the object is generated. It allows to practice alone because the user 10 can control the entire device. It allows to vary the speed (0 to tens of km / h) to suit all uses.
• the device according to the invention therefore comprises in particular at least one motor 5 (preferably two motors), two winding coils 4, a power supply system with a cable 7 and a feed group 8 and a main cord (comprising the two segments 3) and a small additional perpendicular cord 9. It can be used with a pulley 2 or not as can be seen in the various embodiments illustrated.
• the device also includes a remote control that is wired or wireless.
• the device is transportable (ex trunk car or with wheels and handles in wheelbarrow mode).
• the system uses one or two motors 5.
• a single motor 5 it will cause one or the other of the two coils 4 winding while braking that which is not driven (mechanical brake, dynamo type or other like the regenerative braking of electric motors).
• the anchor points 1 have a tension induced by the force necessary to tow the practitioner. No additional voltage is needed.
• the device is controlled by the user, no operator is required. Alternatively, you can use an operator, for example if the system is used by a beginner or as part of an animation.
• the user can adjust the speed and / or torque and has a limit and kill function to automatically stop the system in case of an emergency or limit switch.
• the command used by the practitioner communicates with or without wire with the motors. It is waterproof and resistant to shocks and dust and can be integrated into the lifter on the rope 9.
• the system is quiet when used with electric motors but can be used with other types of motors, eg heat.
• the system can be used with 8 batteries or sector power source but also solar panels or any other source of electricity and / or equivalent and appropriate energy.
• the system can use a nylon rope, microfiber or other, or a metal rope (cable).
• the system is modular so that batteries 8 and drive system can be transported separately by people or even one person.
• the device comprises one or two motors 5.
• the motors 5 can therefore have a dual role: that of drive and that of brake.
• a single motor 5 When a single motor 5 is used it will selectively couple to a coil or the other in the direction of travel. A mechanism such as mechanical brake, dynamo or regenerative braking will slow the unwinding coil.
• the motors 5 can each be at one end of the segment 3 which eliminates the need for a pulley 2 at the end of segment 3.
• each motor 5 has its own power supply (7 , 8) and is completely autonomous although communicating with each other to coordinate their operation.
• This embodiment is illustrated in Figure 2 for example in the application to water skiing.
• a traction system comprising a coil 4, a motor 5 and a control 6 which are attached (for example by a strap 1 ') to a fixed point 1.
• Each traction system has its own feed system 7, 8.
• a common feed system can also be used or a feed system can be used on site.
• the system according to the invention comprises for example dimmers 6 which control the motor or motors 5.
• dimmers 6 which control the motor or motors 5.
• the motors 5 rotates a winding spool 4 for the main pulling rope. While one motor 5 winds the rope, the other unrolls the rope allowing said rope, through a pulley, to form a loop.
• length of segments 3 is from 50m to 200m in most cases but can go beyond or below this distance.
• a small secondary rope 9 (about 10m) is attached, at the end of which is a rudder which is held by the user 10.
• the control 6 of the engines 5 can be integrated in the rudder or be a distinct element usable by someone other than the user of the system.
• the whole is preferably mounted in a transportable frame 20 which makes the mobile system easily, especially in a trailer or in a vehicle trunk.
• the system constantly checks the tension and speed in the main rope so that it only needs to provide the necessary force to tow the athlete, ie a few tens of kilos or more. This measurement can be done at the level of the coils 4 for example, by known means.
• the machine will provide more energy the time needed to reach the nominal speed. This is done by connecting the inputs and outputs of the two dimmers that drive the electric motors (or the appropriate controls of the motors) or coupling the motor and the brake. By coupling their inputs and their outputs they communicate to each other their state of speed and tension in order to maintain the desired speed (about 8.5m / s for use on the water for example) and to rectify it if necessary.
• the present invention provides a segment 3 of variable length, this segment 3 may be a loop of variable length which is not known in the state of the art such as the application WO0156855A1.
• the device is powered by batteries / accumulators 8 (LIFEP04 for example) and is movable by means of wheels or tracks and is easily stored in the trunk of a vehicle.
• the tracks or wheels can be driven by an auxiliary motor and a wired or wireless control which allows the device to move autonomously according to its weight or the place where it must be implemented (for example for the transport of loads on an inclined plane).
• the invention makes it possible to do without the shore (the simple winch implies having an open bank to be able to unwind the rope) and does not require a fixed installation (because the rope tensions are low).
• the invention can be parameterized freely (speeds, voltages, reaction times, etc.) allowing it different uses than water sports. It is adaptable for the transport of objects (removals), people (rescue) or other sports and other applications.
• the programming of the motor control makes it possible, by linking the two motors, to interregulate them to obtain the desired behavior and maintain the necessary characteristics (voltage, traction speed, etc.).
• FIG. 5 schematically illustrates an embodiment of the transportable chassis, referenced 20.
• the chassis 20 comprises in particular the coils 4, the motor (s) 5 and the control (controller or the drive).
• the frame 20 can be directly attached to the fixed point 1, or as illustrated in Figure 5, the frame can be mounted on a base 21.
• the base 21 is itself secured to the fixed point 1 for example by a strap 1 'and the frame 20 is mounted on the base 21 by a support 22.
• the support 22 is a rotatable support for rotating the frame 20 relative to the base 21 around a vertical axis passing through the support 22. This allows to orient the frame relative to the segment 3.
• the degree of freedom in rotation is for example achieved by a bearing which can be either in the base 21 or in the frame 20. It is possible to allow the rotation of the frame 20 relative to the base 21 free or to provide means of blocking, which are implemented for example once the frame 20 is oriented as desired.
