    The invention relates to a wind turbine according to the preamble of claim 1.
    A known turbomachine especially for wind currents according to the document DE-A-
    2014 003 752 is provided with a wing arrangement with two wings aligned parallel to each other. A guide device ensures linear movement of the wings in the event of an oscillating, opposite stroke movement of the wings along a respective stroke. Devices are provided for pivoting the wings about a pivot axis aligned transversely to the stroke path for variable adjustment of the stroke path. In addition, a gear arrangement is provided which enables the lifting movements of the wings to be converted into a unidirectional rotational movement. A connection to a generator or a pump for generating electrical energy can thus be achieved.
    In US-A-2012/0 235 417 a reciprocal transmission device from kinetic to electrical energy, especially wind energy, is also disclosed. Wings arranged one above the other are pivoted in pairs up and down about an axis by means of a height adjustment. By coupling the wings via a linkage, electricity is generated by a generator driven with them.
    The invention has for its object to improve a wind turbine of the type mentioned in such a way that with it a simple, space-saving and stable structure enables efficient energy conversion and it is suitable for mobile use as required.
    This object is achieved according to the features of claim 1.
    In this wind power plant, which comprises at least one wing that can be aligned against the wind direction, at least one longitudinal element that can be tilted, and a holding device that guides the latter, according to the invention, the at least one wing is oriented approximately vertically in terms of its extension and its pivot axis, and it is on the at least one longitudinal element arranged transversely to this is held rotatably about the pivot axis. The wing can be moved back and forth together with the longitudinal element by the bobbing generated by the wind and they are set up free-standing, stop means being provided for limited pivoting of the at least one wing.
    The respective longitudinal element is mounted in an approximately horizontal longitudinal extension opposite to the pivot axis for the wing on a vertical axis and by pivoting back and forth a generator or the like coupled to the axis can be driven.
    Advantageously, two or more longitudinal elements are superimposed in approximately horizontal longitudinal extent on the vertical axis, on which the at least one wing is pivotally mounted on the pivot axis. This results in a very stable, yet light and little space-consuming arrangement of a wind turbine as a whole.
    The invention and further advantages thereof are explained in more detail below using exemplary embodiments with reference to the drawing. It shows:
    1 shows a schematic perspective view of a wind power plant according to the invention; and
    Fig. 2 is a schematic plan view of the wind turbine according to Fig. 1 with various indicated positions of the wing or the longitudinal elements connected to them.
    Fig. 1 shows a wind turbine 10 which is provided with a rockable wing 11 which can be aligned against the wind direction W and which can be moved back and forth about a pivot axis A1. This wing, which consists of two partial wings, is pivotably held at its lower end or approximately in the middle, each with a longitudinal element 15, 20 which can be rotated about an axis A2. These two longitudinal elements 15, 20 arranged one above the other are operatively connected to an energy conversion device 16 via this axis A2.
    According to the invention, the wing 11 is vertically aligned in its area dimension as well as its pivot axis A1 and it is held rotatably about the pivot axis A1 on the two longitudinal elements 15, 20 arranged transversely to these. The wing 11 can be moved back and forth together with the longitudinal elements 15, 20 by the rocking caused by the wind. At least one stop means 25 is provided for a limited pivoting thereof. The wing 11 and these longitudinal elements 15, 20 with the axis A2 are set up free-standing and this results in a simple and space-saving construction of this wind power plant.
    The longitudinal elements 15, 20 are in an approximately horizontal longitudinal extent one above the other and opposite to the pivot axis A1, they are connected to the vertical axis A2 and a holding device supporting them. This holding device 23 has a shaft 22 which rotates the axis A2 and a base which fixes it. The longitudinal elements 15, 20 each consist of oval flanges 12, 13, 32, 33 and rods 14, 34 connecting them.
    For this limited back and forth pivoting of the wing 11, this stop means 25 is provided which, for example, from a protruding from the upper longitudinal member 15 holding member 28, from one at the pivot axis
    CH 714 653 A2
    A1 provided eccentric 26 and a tension member 27 connecting them, which consists of a tension spring, a rope or a similar element. When the wing 11 is pivoted into an end position, the eccentric 26 connected to the pivot axis A1 is also pivoted and the wing 11 is pivoted about twice as compared to the longitudinal element 15 and exceeds as soon as the predetermined spring tension force is large enough or the rope is stretched this force is the wind force on the wing 11 and the latter is moved in the opposite direction.
    This stop means 25 is designed with the eccentric 26 and the tension member 27 such that it sets the wing 11 at an angle to the longitudinal element 20 in the idle state, so that as soon as wind arises, a torque on the wing by the on the wing acting wind power is generated.
    A wing brake, for example eddy current brakes, magnetic brakes, dampers, such as oil dampers, air dampers, etc., could also be used as lifting means, so that a long-lasting functionality of the system is ensured.
    This axis A2 is coupled, for example on the underside, to the energy conversion device 16 by means of a gear with gear wheels 17, 19 and a toothed belt 18. By pivoting the axis back and forth, for example, a generator or the like can be driven, by means of which electrical current can be generated, which can be connected to an end user via a cable connection, not shown. Another form of energy, such as generating a gas pressure or conveying a medium, could also be provided.
    The wing 11 and with it the longitudinal elements 15, 20 can be rotated through 360 ° about the axis A2, so that the wing can be automatically aligned in any position against the wind direction W, since this causes a torque on the wind and one The swinging of the wing is stimulated with the help of the spring element when the wind comes up.
    The wing surfaces of the respective wing 11 in front of and behind the vertical pivot axis A1 is advantageously dimensioned differently, so that when the wind comes up, a torque is caused on this and consequently the back and forth pivoting of the wing.
    It is in the operating state by this swinging or rocking wing 11 on the one hand and these reciprocating longitudinal elements 15, 20 on the other, two oscillating circles acting independently of one another, which are, however, coordinated with one another so that a total of one uniform vibration of the wing 11 and the coordinating back and forth movement of the longitudinal elements 15, 20 results.
    Fig. 2 shows the wing 11 and the cooperating with this longitudinal element 20 from above in the middle and the two end positions. The lower longitudinal element 15 is located on the same plane with the axis A2 below this longitudinal element 20 and is therefore not visible.
    In the middle position of the longitudinal element 20, the wing 11a is pivoted by an angle a to the longitudinal extent of the longitudinal element, as shown in a line. Depending on the setting, this angle a can be up to approximately, but less than 90 °.
    If the longitudinal element 20 now swings out into the one end position 20 'by the force exerted by the wind on the wing, as illustrated in dashed lines, the wing 11' is pivoted such that it extends in the longitudinal direction to the longitudinal element 20.
    Now, the longitudinal element 20 'is pivoted by the stop means 25, as shown in Fig. 1, in the other direction by the force acting on the wing by the force to the other end position 20' of the longitudinal element, as illustrated by dashed lines is. The wing 11 a is pivoted into the other position with the angle a to the longitudinal extent of the longitudinal element and then the wing 11 is rocked again in the longitudinal direction to the longitudinal element 20.
    This explains that, in the operating state, on the one hand this rocking movement of the at least one wing 11 forms a uniform resonant circuit and on the other hand this back and forth turning of the longitudinal elements 15, 20 takes place synchronously with an approximately constant rotational speed in both directions.
    The at least one wing 11 is made of a light material, such as a textile or a light plastic.
    The invention is sufficiently demonstrated with the exemplary embodiments explained above. However, it could also be disclosed by other variants. For example, a plurality of blades or pairs of blades arranged in succession at certain intervals could each be mounted on a longitudinal element so that a wave movement of the air flow is generated and the energy transmission is increased therefrom.
    It would suffice for a small version of a system if only one longitudinal element were advantageously used in the middle of the wing. A plurality of wings could also be pivoted on the axis one above the other. The wings could also be arranged somewhat differently from the vertical orientation.
    The wing and the longitudinal elements could also be protected at the top and bottom by a protective wall, wherein a solar panel or the like could be installed on the upper wall.
