Description

BRIEF DESCRIPTION OF DRAWINGS

[0015] FIG. 1 illustrates an example of the bar.

DESCRIPTION

[0016] Examples of the bar are explained in more detail below using the single schematic drawing of FIG. 1.

[0017] FIG. 1 shows a strongly schematized view of a bar 1 according to the disclosure. The basic structure of the bar 1 is explained in the prior art described at the beginning, so that only the features essential for understanding the disclosure are explained here. Accordingly, the bar 1 has floaters 2, 4 at each of its two end portions, each of which encloses a back line 6, 8 and ensures that the bar does not sink when the kiter releases it. The two back lines 6, 8 are each guided to one end portion of the bar and enter there into an enclosed or partially open hollow profile 10 of the bar. The back lines are then redirected inside the hollow profile 10 and/or guided to a winder, which is located at the right end portion, i.e. in the transition area of the floater 2 to the hollow profile 10. As described in the prior art, this winder (also called a trimming device) has a drum on which the back lines 6, 8 are wound. These back lines 6, 8 can also be designed to be continuous, so that a central section is connected to the drum.

[0018] In order to operate the winder, the bar is provided with an electric motor 12, which is either integrated in the housing of the bar end or is attached to it. This electric motor drives the winder or respectively its drum directly or via a transmission in order to wind or unwind the back lines 6, 8. A button or slider 14 can be provided to operate the electric motor 12, which, for example, can be adjusted upwards in the direction of the kite for extending and downwards in the direction of the kiter for shortening, so that the direction of rotation of the winder is determined accordingly. This button 14 is located in an area of the bar 1 which is easily accessible by the kiter during kiting in order to be able to react quickly to wind changes.

[0019] The electric motor 12 is supplied with power by a battery 16, which is integrated into the hollow profile 10, for example. As indicated by the dashed lines in FIG. 1, the battery 16 can also be placed at another location of the hollow profile 10. In principle, it is also possible to arrange two batteries symmetrically for weight distribution. These batteries 16, 16 can either be exchangeably mounted and/or can be charged via a charger connection 18, for example by means of a USB connection or a contactless charging station 20. This charging station can in turn be equipped with a large battery, so that charging is also possible independent of the power grid.

[0020] In the event that the battery 16 is defective or has not been charged due to inattentiveness on the part of the kiter, the bar 1 is configured with an emergency actuation, which can consist of, for example, a winder handle being provided in a manner known per se, which still allows the kite to be trimmed in the event of a power failure. In a simpler solution, in addition to the button 14, a mechanical button can be provided via which the winder is mechanically unlocked so that the two back lines 6, 8 are extended and the kite correspondingly assumes its flattest trim position, with which the kiter can then return to charge the battery.

[0021] In one version, the bar 1 is additionally equipped with a radio module 24, which makes it possible to receive the signal of a radio station, e.g. a remote control 26, so that a kite instructor, for example, has the possibility to control the winder/trimming device from the beach in order to trim the kite in an optimal way for the respective student.

[0022] The bar depicted in the FIGURE also has two front lines 28, 30, which are combined to form a depower line 32. This line extends through a bushing 34 of the bar 1 towards a chicken loop 36. On the depower line 32, a stopper 38 is also adjustably guided, which limits the path of the bar 1 when it is released.

[0023] Approximately in the middle of the bushing 34, a display 40 is provided on the hollow profile 10 or respectively on the bar 1, on which essential function parameters, e.g. the line length, the charge state of the battery or alsowith suitable sensorsinformation about the speed, the course and/or the altitude (in case of a jump) can be read. The power supply for this display is also provided by the battery or batteries 16.

[0024] Of course, a conventional mechanical display can also be used instead of the electrical display to show the current line length in the usual way. The charge state of the battery can also be indicated by diodes or the like.

[0025] A bar for steering a kite is disclosed. This bar is configured with a trimming device for the back lines (back-line trimming device), which is adjustable by a motor, preferably an electric motor.
