Definitions
- the invention relates to water skis with a floatable ski body to which, in addition to a binding, a travel drive is assigned which comprises a rotary drive unit with a rotary drive and a screw drive that can be driven with it and with a control device for specifying a drive power.
- Such motorized water skis which can be used to drive on bodies of water without a towing boat or water ski lift, are known, for example, from US Pat. No. 3,646,905 A, US Pat. No. 31 13550 A and EP 0169818 A1.
- the device known from EP 0169818 A1 comprises water skis with a propeller drive, the drive being carried out by a motor arranged in a backpack, which is drive-connected to the propeller shaft via a flexible shaft.
- the rotary drive turns up the screw drive, a ship's propeller or a jet drive and accelerates the skis.
- the increasing buoyancy of the water skis with increasing speed they swim on the
- US Pat. No. 3,646,905 A is similar in construction to a catamaran with an outboard motor arranged between the hulls.
- US 31 13550 A water is drawn in from under the skis, fed to a rucksack via lines and the water expelled from the back of the rucksack for propulsion.
- the invention is therefore based on the object of water skiing
- the invention achieves the stated problem in that the water skis of a water ski pair each have a rotary drive unit, each with at least one
- Communication device include which the rotary drives of both water skis depending on drive sensor data and default data of the
- the two water skis are each equipped with a preferably electric or internal combustion engine, a propeller or jet drive and all the components required for the drive. To avoid dangerous driving conditions, the same
- the drive sensor can, for example, be a speed sensor, a torque sensor for determining the drive power or a force sensor for measuring the drive thrust of the rotary drive unit or the like.
- the speed can be configured as a handle
- Control device are specified, for example wirelessly via a
- Radio network is connected to the communication devices of the two skis.
- an intelligent one is required
- Water skis make controlled movements and uncontrollable driving conditions can be prevented.
- the rotary drive unit is a jet drive, the outlet nozzle of which is arranged in the area of the water ski end in the area of a water line.
- the outlet nozzle of the jet drive can be mounted on a jet drive body so as to be pivotable about at least one axis, in order to be able to trim the water skis, if necessary, according to the skiing ability of the skier.
- This setting can be made permanently. If readjustment is to be possible during operation, the outlet nozzle of the jet drive can be mounted on a jet drive body so as to be pivotable about at least one axis with an actuating drive that can be adjusted as a function of specification data from the control device.
- the water skis can be equipped with a sensor measuring at least one angle of inclination about the longitudinal axis of the water ski to detect the position of the water ski on the water.
- Possible sensors for detecting the position of the water ski on the water are, for example, inertial sensors, acceleration sensors, gyro sensors, inclination or angle sensors and the like. Like. Will the water skier for example driving a left turn, he leans to the left and he drives to the left. If the sensors of both skis now recognize that a certain tilt angle to the left is predetermined by the skier, then for example the right ski can be accelerated compared to the left ski in order to make cornering easier.
- An acceleration sensor can also detect the speed at which a movement is being made, i.e. it is detected whether, for example, tight cornering maneuvers are to be driven, as is common in surfing or water skiing. Changes in the direction of travel can also be made or supported by a corresponding control of the outlet nozzle with the associated actuating drive.
- the two skis continuously communicate with one another via the communication devices; this is preferably done wirelessly, for example via a Bluetooth connection.
- a contact sensor can be provided in the binding, or a cuff attached to the body via a rip cord with the water ski be connected. If the driver falls, the rip cord is released from the skis and the rotary drive is switched off immediately.
- the water skis can also be equipped with a position sensor to detect their mutual position on the water. If the distance between the two skis changes laterally or as a result of a longitudinal offset, this should in particular be recognized and, if necessary, corrected by appropriate control of the drive thrust or the outlet nozzle.
- the skis can also be equipped with DGPS sensors in order to correct mutual changes in position. Solutions with strong magnets, camera solutions, echo sounders and the like are also available. like. conceivable. With the aid of a force and / or pressure sensor assigned to the binding, in particular the binding base plate, it can be detected, for example, when the water skier applies pressure to the left, right, back or front.
- the water skier gets by while driving, for example
- the water skis can be mechanically connected to a coupling device.
- the rotary drives of both water skis would then preferably be rigidly coupled or to synchronize.
- the water skis can optionally be connected to a type of monoski or surfboard by means of the mechanical coupling device.
- the skis With a mechanical coupling device, the skis can be easily connected and also detached again. In particular, the release can take place either via a switch by means of the remote control or, if necessary, manually. This makes it easier to drive out of the water, for example. When the skis are connected, it is much easier to position yourself over the skis and to slip your feet into the binding before the coupling device is released before or after you set off.
- the water skis can be equipped with a hydrofoil, the rotary drive units preferably being arranged in the area of the wings of the hydrofoils.
- Programming for example a selection of an operating mode, can be made externally at any time.
- a pair of ski poles can be assigned to the pair of water skis, the ski poles being equipped with floats at the end facing away from the grips and at least one of the two ski poles being equipped with an actuator for operating the control device.
- Control device to have one in the left and one in the right hand. So you can control the speed of the left ski with the control device in the left hand and the right ski with the control device in the right hand. This makes cornering particularly easier. Since the speed of both skis cannot be exactly the same, there is the option of using a button on one of the two remote controls to control both skis at the same time.
- the communication device avoids invalid, in particular dangerous driving conditions. Does the driver want that now, for example one of the motorized water skis drives faster than the other, so it can only increase the speed of an individual by a certain percentage of the current speed.
- a programmed lock prevents the ski from being accidentally driven too fast, i.e. the skis from drifting apart.
- the skis can therefore carry his body weight.
- the second variant is that the motorized water skis cannot bear the weight of the driver unless he is traveling at a certain speed. Only when the water skis are moved across the water at the appropriate speed will the necessary buoyancy force be achieved to lift the rider out of the water. In order to be able to improve the stability or the contact surface of the water skis with a few fland handles, to make driving for children or
- a pressure sensor can be assigned to the binding, in particular a binding plate, of the skis. As long as a skier exerts sufficient pressure on the pressure sensor, the skis can be operated in the desired manner. If this pressure does not apply as a result of a fall or the like, the rotary drives are switched to a powerless state or the binding is released in order to prevent the skis from continuing to drive uncontrolled. It is also advantageous to assign a humidity sensor to the remote control. This recognizes that the remote control is submerged in the water in the event of a fall and in turn switches the rotary drive to zero power.
- a personalized unlocking mechanism can be provided to prevent unauthorized use of the water skis by third parties. With this unlocking mechanism it is possible
- a fingerprint sensor on the remote control or on the skis to activate the control to ensure that the skis can only be operated by authorized persons.
