Definitions

  • the invention relates to a surfboard with a tread and a drive for the surfboard, wherein one end of a rope is attached to the bow of the surfboard and another end of the rope has a handle.
  • surfboards are well known. Surfboards are in the English language boards without sails, on which a surfer can ride by the advance of a wave. In German parlance one speaks here of surfing.
  • the inventive surfboard builds on this sport.
  • the surfer stands on the surfboard and drives preferably without caused by sail or waves propulsion over the water.
  • US2002 / 0056408 A1 discloses a surfboard with a gas cable with a handle at one end for the surfer. The other end of the throttle cable is attached to the bow of the surfboard and connected to an internal combustion engine.
  • US 6,192,817 B1 discloses a surfboard with an internal combustion engine and a gas lever addressed to a gas cable.
  • US 3,324,822 also relates to a surfboard with a throttle and a gas cable that controls the advance of an internal combustion engine.
  • a handheld controller includes a gyroscope function.
  • the surfboard has a drive to do so.
  • Surfboards with drive are known for example from DE 20 201 1 051 071.
  • Powered surfboards are not dependent on high waves, but they can also be used in windless and low-surf waters. The surfer did not even paddle on the surfboard, because he experienced propulsion through the drive.
  • the surfboard according to the invention has an electric drive, preferably in the rear area of the surfboard on; this is preferably a jet propulsion.
  • the jet engine has an opening on the underwater surface of the surfboard and a water channel that extends from the underwater surface to a nozzle on the rear end side of the surfboard.
  • the nozzle may be designed to be pivotable or non-pivotable.
  • a rotor is provided in the water channel.
  • a rotor is understood to mean both a propeller and an impeller. In this case, water is sucked into the water channel by the high speed of the rotor and conveyed out back against the direction of travel from the nozzle, whereby the surfboard is given the necessary feed.
  • the rotor is connected via a drive train with an electric motor, which is supplied via a preferably replaceable accumulator with power.
  • the motor is also electrically conductively connected to a controller which transmits control signals to the motor and thus controls the power of the drive, that is to say the speed of the surfboard.
  • the controller receives the necessary control signals via a preferably hand-held remote control.
  • the surfboard preferably has an inflatable body part and a drive unit.
  • the body part can be made of a drop-stitch material.
  • the inflated body part has a recess at the rear, in which the drive unit is detachably insertable.
  • the surfboard can also consist of a solid hull made of a non-inflatable material. In the drive unit or in the interior of the hull a drive for the surfboard, preferably a jet propulsion, is provided.
  • the controller is signal-connected to a receiver, the receiver receives the signals of the transmitter of a radio remote control.
  • a handle has a throttle that is operatively connected to a transmitter of the radio remote control.
  • the transmitter is arranged in the handle, and by actuation of the throttle lever, electrical signals are generated and delivered to the transmitter, which converts them into radio signals receivable by the receiver and convertible by the controller into drive control signals.
  • a radio link has the advantage over a cable connection that no cables that disturb the surfers are present and no fuselage breakthroughs are necessary for plug connections.
  • the handle is connected to the surfboard by means of a cable.
  • One end of the rope is attached to the bow and another end of the rope is releasably connected to the handle.
  • the surfboard thus has two different types of body.
  • the rope connected to the handle and board in the first embodiment allows the surfer to advantageously maintain his balance more easily. By loosening the handle from the rope, it is possible in the second construction, making surfing for the surfer free and difficult by having no train connection to the surfboard but holds the handle with the remote control in one hand and hold his balance without rope got to.
  • one end of the rope is detachably connected to the bow. By loosening both ends, the rope can be completely dispensed with, and it can be left on land during exercise.
  • the control of the surfboard is advantageously kept very easy to handle.
  • the radio remote control preferably comprises an RC (Remote Control) radio remote control.
  • the RC radio remote control is a commercially available radio remote control, which is therefore inexpensive and proven.
  • RC radio remote controls which transmit radio signals by pulse modulation in the ISM band, have proved to be particularly reliable in the transmission of the control values. Compared to amplitude modulation, pulse modulation is less susceptible to interference in radio signal transmission. Conveniently, the transmission of the radio signals is in the 2.4 to 2.5 GHz ISM band. In principle, other ISM bands for transmitting the radio signals are conceivable.
  • the handle has a grip portion for grasping with a hand of the surfer, wherein a center of gravity is arranged centrally in the grip portion.
  • the surfer stands on the surface of the surfboard, and gripping the handle of the rope attached to the bow can help the surfer to keep his balance. He can exert a significant force on the handle on the rope and the bow, which can correspond to his body weight or a multiple of his body weight during short power peaks.
  • one end of the rope is attached to the bow of the surfboard with a fastener and / or another end of the rope is connected to another fastener with the handle.
  • the one end of the rope can thus be permanently or detachably attached to the bow and the rope can be permanently or detachably attached to the handle with the other end of the rope.
  • the fastening means and the further fastening means are releasable without tools.
  • the fastener and / or the other fastener on a snap closure so that the handles can be easily replaced and rope and handle can be removed from the bow of the surfboard, and the handle can be used as a pure remote control without rope.
  • the latter has the advantage that a skilled surfer who does not need the rope to hold the balance can use the handle as a radio remote control, and then no troublesome rope is present.
  • a fastening means and / or further fastening means also be provided in each case a node.
  • the further attachment means for the other end of the rope is arranged at a distance perpendicularly and centrally from the grip portion.
  • gripping the grip portion creates a center of gravity in the middle of the grip portion so that no torque acting on the wrist and the handle can be kept longer by the surfer while pulling.
  • the throttle lever is arranged in the grip so that the surfer can operate with one hand, with which he holds the handle, the throttle and generates correlated with the position of the throttle lever control values.
  • the surfer can hold his balance well on the surfboard by firmly holding the handle on the one hand and on the other with the same hand also give gas at the same time.
  • the handle is waterproof, since the surfer can fall from the board, so that the handle falls into the water.
  • the handle preferably also has an average density of p ⁇ 1 gl cm 3 , so that it floats on the water.
  • the handle is preferably formed along its outer circumference triangular shape with rounded corners and in the interior also substantially triangular, wherein the Handle portion is preferably designed ergonomically.
  • the handle There are various forms for the handle conceivable, for example, semicircular, circular, oval shapes, etc.
  • the throttle lever is designed as a retractable push button in the handle portion.
  • the push button is preferably operated by means of the index finger.
  • the drive control has a movably arranged throttle lever, which can be actuated externally on the handle with a surfer's thumb.
  • the throttle lever may be pivotally mounted about an axis and having a pressure surface placed in front of the thumb upon natural gripping of the grip portion.
  • the throttle lever is arranged inside the handle.
  • the throttle is conveniently operated with the forefinger or middle finger of the surfer.
