[0039] Examples of embodiments of the present invention will now be described with the aid of figures. They show:

[0040] FIG. 1 a perspective oblique view of an example of an embodiment of a winding unit of a winding device according to the invention,

[0041] FIG. 2 a further perspective oblique view of the winding unit in FIG. 2,

[0042] FIG. 3 a top view of the winding unit from to FIGS. 1 and 2,

[0043] FIG. 4 a perspective oblique view of an example of an embodiment of a winding device according to the invention, and

[0044] FIG. 5 a schematic representation of a parachute with a winding device according to the invention.

[0045] FIG. 1 depicts a perspective oblique view of an example of an embodiment of a winding unit 10 of a winding device 30 according to the invention, not depicted here. A reel 11 is rotatably mounted on a shaft 13 inside a reel housing 12 of the winding unit 10. The shaft 13 protrudes out of the reel housing 12. The shaft 13 is coupled with a reel drive 14 and is driven by said drive. In this example of an embodiment, the reel drive 14 is arranged outside of the reel housing 12. Alternatively, it is possible to arrange the reel drive 14 inside the reel housing 12 and the shaft 13 completely inside the reel housing 12.

[0046] In this example of an embodiment, the reel drive 14 is designed as an electric motor. The reel drive 14 can have a separate housing and/or be mounted in a support structure 15 as shown here, or alternatively be supported on the support structure 15 or on the reel housing 12. The reel drive 14 is connected to an energy storage device 17 (see FIG. 2) by means of two electrical lines 16a and 16b, one positive and one negative line in the present case, said energy storage device being arranged on the back of winding unit 10, which is not visible here. Nevertheless, it is possible to combine the two electrical lines 16a, 16b into one common electrical line 16.

[0047] The reel housing 12 is designed to be hinged for the purpose of inserting a line. To this end, the reel housing 12 consists of an upper reel housing part 12a and a lower reel housing part 12b, which are connected to each other by means of a hinge 18 located on the back of the reel housing 12.

[0048] The lower reel housing part 12b completely accommodates the reel 11 in this example of an embodiment and is therefore larger than the upper reel housing part 12a. The upper and lower reel housing parts 12a, 12b each feature a housing projection 19a, 19b with trapezoidal bases. The housing projections 19a, 19b have frontal recesses that correspond to each other in such a way that the recesses form a common housing opening 20 for at least one line not shown here. Alternatively, they may form separate recesses for one line each or have several recesses for several lines.

[0049] Within the housing projections 19a, 19b, three stripping and tensioning devices 21a.1, 21a.2, 21a.3, 21b.1, 21b.2, 21b.3 are arranged in pairs. The stripping and tensioning devices 21a.1, 21a.2, 21a.3, 21b.1, 21b.2, 21b.3 arranged in pairs are arranged essentially equidistant from each other. The number of stripping and tensioning devices 21a, 21b can also be greater or smaller and in particular 1, 2, 3, 4 or 5. The distances between the stripping and tensioning devices 21a.1, 21a.2, 21a.3, 21b.1, 21b.2, 21b.3 can also vary. In particular, different stripping and/or tensioning devices 21a.1, 21a.2, 21a.3, 21b.1, 21b.2, 21b.3 can also be used.

[0050] In the present case, all stripping and tensioning devices 21a.1, 21a.2, 21a.3, 21b.1, 21b.2, 21b.3 consist of a wiper rubber. The pairs of an upper and a lower stripping and tensioning device 21a.1 and 21b.1, 21a.2 and 21b.2, 21a.3 and 21b.3 are each arranged corresponding to each other in such a way that no opening remains between them. When winding up the line, the line must therefore deform the wiper rubbers with force in order to be wound onto the reel 11.

[0051] FIG. 2 depicts a perspective oblique view of the winding unit 10 according to the example of an embodiment in FIG. 1. Here, one can see the opposite side of the winding unit 10 to the side view in FIG. 2. In particular, the energy source 17 and the hinge 18 can be recognized.

[0052] FIG. 3 shows a top view of the winding unit 10 in an open state according to the example of an embodiment in FIGS. 1 and 2. Here, the upper reel housing part 12a has been opened by means of hinge 18, so that the upper reel housing part 12a and the lower reel housing part 12b are only in contact with each other by means of the hinge 18.

[0053] In this open state, a line, not shown, can be wound onto the reel 11 very easily; in the closed state, after closing the reel housing 12, the line can be taken up by the reel drive 14. For this purpose, the reel 11 has a reel flap 11 a which can be opened and into which at least one line can be inserted.

[0054] Three discharge devices 22.1, 22.2, 22.3 are arranged in the lower housing projection 19b of the lower reel housing part 12b. The discharge devices 22.1, 22.2, 22.3 are designed as elongated slots along the lower housing projection 19b. This provides an opening from the reel housing 12 to the outside through which water and dirt, such as grains of sand, that have been scraped off by the stripping and/or tensioning devices 21a.1, 21a.2, 21a.3, 21b.1, 21b.2, 21b.3 can be discharged.

[0055] FIG. 4 depicts a perspective oblique view of an example of an embodiment of a winding device 30 according to the invention. Four identical winding units 101, 102, 103, 104 are arranged on a device housing 31 of the winding device 30. Alternatively, three, five or more identical winding units 10 can be arranged on the device housing 31. The winding units 10.sub.1, 10.sub.2, 103, 10.sub.4 need not be structurally identical. The winding units 10.sub.1, 10.sub.2, 10.sub.3, 10.sub.4 are each detachably fastened to the device housing 31 by means of the holding devices of the device housing 31, not visible here.

[0056] For example, the holding device of the device housing 31 can be a groove and a lower side of the winding units 10.sub.1, 10.sub.2, 10.sub.3, 10.sub.4 can have corresponding tongues to engage in the groove. In addition, the holding devices may feature locking elements for locking the tongue and groove connection, which prevent the tongues of the winding units 10.sub.1, 10.sub.2, 10.sub.3, 10.sub.4 from being released from the grooves.

[0057] The device housing 31 is also designed as a fastening clip 31. The fastening clip 31 features a cavity with an opening to receive a handlebar 40 for a stunt kite. The fastening clip 31 grips around the handlebar 40 and clamps it tight. The handlebar ends 40.1, 40.2 of the handlebar 40 protrude from the cavity.

[0058] In the present case, the clamping force of the fastening clip 31 is provided by the elastic design of the fastening clip 31. To clamp the handlebar 40, the opening and cavity of the fastening clip 31 are elastically widened and the fastening clip 31 is placed on the handlebar 40, where the elastic restoring force provides the clamping force. To release the fastening clip 31 and thus the winding device 30 from the handlebar 40, the fastening clip 31 is pulled in the direction from the opening of the cavity away from the handlebar 30.

[0059] The winding units 10.sub.1, 10.sub.2, 10.sub.3, 104, in turn, each have reel drives 14.sub.1, 14.sub.2, 14.sub.3, 144, which are each connected to an energy storage device 17.sub.1, 17.sub.2, 17.sub.3, 17.sub.4 by means of an electrical line 16.sub.1, 16.sub.2, 16.sub.3, 16.sub.4. In addition, the energy storage device 17.sub.1, 17.sub.2, 17.sub.3, 17.sub.4 is each connected to an actuating unit 24.sub.1, 24.sub.2, 24.sub.3, 24.sub.4 by means of an electrical line 23.sub.1, 23.sub.2, 23.sub.3, 23.sub.4. The actuating units 24.sub.1, 24.sub.2, 24.sub.3, 24.sub.4 each have an activation button to activate the reel drive 14.sub.1, 14.sub.2, 14.sub.3, 14.sub.4, which are designed here in the form of electric motors. Each of the depicted lines 50.sub.1, 50.sub.2, 50.sub.3, 504, which are received in the reels 11 of the winding units 10.sub.1, 10.sub.2, 10.sub.3, 10.sub.4, can be wound up by means of one of the activation buttons.

[0060] The energy storage devices 17.sub.1, 17.sub.2, 17.sub.3, 17.sub.4 are also connected to each other by means of an electrical line 32 via a common actuation unit 33. On the common actuating unit 33 there is a common activation button 33a which starts the reel drives 14.sub.1, 14.sub.2, 14.sub.3, 14.sub.4 to simultaneously wind up all lines 50.sub.1, 50.sub.2, 50.sub.3, 50.sub.4 and a common activation button 33b which activates the motor brakes of the reel drives 14.sub.1, 14.sub.2, 14.sub.3, 14.sub.4 to simultaneously unwind all lines 50.sub.1, 50.sub.2, 50.sub.3, 50.sub.4.

[0061] FIG. 5 shows a schematic representation of a parachutist 70 hanging from a parachute 60 with a winding device 30 according to the invention. The winding device 30, shown here only as an example, is arranged between two straps 61, 62 of the parachute 60. For example, the winding device 30 can feature a number of reels 11, which corresponds to the number of lines 50 of the parachute 60.
