Abstract

A retaining device of a water sport device has a drive, which is preferably designed as an electromechanical or electropneumatic drive and via which the foil device can be transitioned from a resting and/or starting position into the operating position and/or from the operating position into the resting and/or starting position. The actuation can take place manually by a person operating the water sport device. The water sport device may already be lowered into knee-deep water near the shore or beach, for example, and guided or driven there in the direction of deeper water. As soon as sufficiently deep water has been reached, the foil device can be transitioned into the operating position, which is at a greater distance from the floating body, by means of the drive. This process can take place automatically when a specifiable or set water depth has been reached or by the release on the part of the person using the water sport device.

First claim

The invention claimed is:

1 . A water sport device comprising:
a floating body; a foil device; a retaining device fastening the floating body to the foil device, wherein the retaining device has a drive via which the foil device can be transitioned from a resting and/or starting position into the operating position and/or from the operating position into the resting and/or starting position; wherein the foil device, which is arranged on a link of the retaining device, has one or more foils and can be transitioned from a resting and/or starting position into an operating position below the floating body via the retaining device, wherein, in the operating position and during a forward movement, the floating body can be transitioned into a position in which it is separated from the water surface due to uplift generated by the foil device, wherein the drive has an energy store, and wherein the energy store has at least one spring and can be preloaded by means of a motor.

2 . The water sport device as claimed in claim 1 , wherein the drive has a gearing via which the motor of the drive is connected to the energy store.

3 . The water sport device as claimed in claim 1 , wherein at least in the actuated state, the spring is connected to the link of the retaining device in such a way that its force can be used at least partially to align the link.

4 . The water sport device as claimed in claim 1 , wherein the energy store can be preloaded in opposite directions by the motor and/or gearing.

5 . The water sport device as claimed in claim 4 , wherein the energy store has two springs that can be loaded.

6 . A water sport device comprising:
a floating body; a foil device; a retaining device fastening the floating body to the foil device, wherein the retaining device has a drive via which the foil device can be transitioned from a resting and/or starting position into the operating position and/or from the operating position into the resting and/or starting position; wherein the foil device, which is arranged on a link of the retaining device, has one or more foils and can be transitioned from a resting and/or starting position into an operating position below the floating body via the retaining device, wherein, in the operating position and during a forward movement, the floating body can be transitioned into a position in which it is separated from the water surface due to uplift generated by the foil device; wherein the retaining device has a braking device which releases and/or brakes the displacement of the foil device.

7 . The water sport device as claimed in claim 6 , wherein the braking force is settable depending on the speed of the floating body.

8 . The water sport device as claimed in claim 1 , wherein the drive of the retaining device is arranged completely in a cutout in the floating body.

9 . The water sport device as claimed in claim 1 , wherein the retaining device has a further link which is pivotably mounted on or in the floating body at one end and pivotably arranged on the foil device at the other end.

10 . The water sport device as claimed in claim 1 , wherein one of at least three links is forcibly guided.

11 . A water sport device comprising:
a floating body; a foil device; a retaining device fastening the floating body to the foil device, wherein the retaining device has a drive via which the foil device can be transitioned from a resting and/or starting position into the operating position and/or from the operating position into the resting and/or starting position; wherein the foil device, which is arranged on a link of the retaining device, has one or more foils and can be transitioned from a resting and/or starting position into an operating position below the floating body via the retaining device, wherein, in the operating position and during a forward movement, the floating body can be transitioned into a position in which it is separated from the water surface due to uplift generated by the foil device; wherein the drive has an energy store; wherein the energy store has at least one spring and can be preloaded by means of a motor; wherein the drive has a gearing via which the motor of the drive is connected to the energy store; wherein the motor, gearing, energy store, and/or a braking device are designed coaxially.

12 . The water sport device as claimed in claim 1 , further including a propulsion device provided for the propulsion of the water sport device.

13 . The water sport device as claimed in claim 12 , wherein the propulsion device comprises at least one propulsion element designed as an impeller or propeller.

14 . The water sport device as claimed in claim 1 , further including at least one control unit designed to control the drive and/or the propulsion device.

15 . A water sport device comprising:
a floating body; a foil device; a retaining device fastening the floating body to the foil device, wherein the retaining device has a drive via which the foil device can be transitioned from a resting and/or starting position into the operating position and/or from the operating position into the resting and/or starting position; at least one control unit designed to control the drive and/or the propulsion device; wherein the foil device, which is arranged on a link of the retaining device, has one or more foils and can be transitioned from a resting and/or starting position into an operating position below the floating body via the retaining device, wherein, in the operating position and during a forward movement, the floating body can be transitioned into a position in which it is separated from the water surface due to uplift generated by the foil device; wherein the water sport device has at least one sensor from a group comprising gyro sensors, speed sensors, position sensors, distance sensors, infrared sensors, proximity sensors, depth sensors, and inclination sensors.

16 . The water sport device as claimed in claim 15 , wherein, for the purpose of geofencing, the control unit is designed to process the signals from the sensors.

17 . A water sport device comprising:
a floating body; a foil device; a retaining device fastening the floating body to the foil device, wherein the retaining device has a drive via which the foil device can be transitioned from a resting and/or starting position into the operating position and/or from the operating position into the resting and/or starting position; a propulsion device provided for the propulsion of the water sport device; a propulsion energy store for the propulsion device, and a storage sensor for monitoring the propulsion energy store, wherein the water sport device is designed to reduce the power or to switch off the propulsion device on the basis of the signal from the storage sensor by means of the control unit; wherein the foil device, which is arranged on a link of the retaining device, has one or more foils and can be transitioned from a resting and/or starting position into an operating position below the floating body via the retaining device, wherein, in the operating position and during a forward movement, the floating body can be transitioned into a position in which it is separated from the water surface due to uplift generated by the foil device.

18 . The water sport device as claimed in claim 14 , wherein the control unit is designed for communication with a control unit of a further propulsion device of the same or of a further water sport device.

19 . The water sport
