The functional surface F1 is arranged on the ground and the functional surface F2 forms the support surface or a support for the support surface. In the present case, the device has two wedge-shaped elements 1 and 2 serving wedge elements 1 and 2 on whose bearing surface L1 or L2 and functional surface F1 and F2 in each case at an acute angle α1 or α2, in the present case about 18 ° converge. The wedge-shaped elements 1 and 2 are present as rectangular wedge elements 1 and 2 formed, wherein the angle between the angle α1 or α2 opposite side or side surface G1 or G2 and the respective functional surface F1 or F2, in this case the angle γ, 90 °. The wedge elements 1 and 2 are rotatably supported with their bearing surfaces in L1 and L2, wherein the bearing surfaces L1 and L2 of the wedge elements 1 and 2 facing each other. Accordingly, the functional surfaces F1 and F2 of the wedge elements 1 and 2 turned away from each other. By relative rotation of the wedge elements 1 and 2 against each other, for example by turning the wedge element 2 opposite the wedge element 1 is the position of the functional surface F1 and F2 of the wedge elements 1 and 2 to each other and thus the position and position of the wing to the ground adjustable.

The functional surface F5 is on the ground 9 arranged and the functional surface F8 forms a support for the wing 10 , The wedges 5 and 6 are present at an angle α5 and α6 of about 18 °, while the wedges 7 and 8th have an angle α7 or α8 of about 9 °. The functional area F5 of the wedge 5 is present on the floor or a base area 9 rotatably mounted. The functional area F8 of the wedge 8th serves as a support for a bearing 11 mounted wing 10 , By twisting the wedges 6 and 8th opposite the wedges 5 respectively 7 is the device of the in 3a presented in the in 3b shown position, wherein between the functional surfaces F5 of the wedge 8th and the functional surface F8 of the wedge 8th the angle β3 is taken.

In the 4a to 4f is a schematic representation of the stepwise rotation of the wedge element 2 opposite the wedge element 1 shown. The above the wedge element 2 shown degree display shows the stepwise rotation of the wedge element 2 at. The below the wedge element 1 indicated degree indication shows the rotation of the wedge element 1 at. In the present case, that of the wedge element 1 not twisted. In the present case, a rotation of the wedge element 2 starting from the in 4a position shown by 360 ° in the in 4f shown position, corresponding to a full rotation of the wedge element 2 , In the individual steps of 4a to 4b , from 4b to 4c , from 4c to 4d , from 4d to 4e and from 4e to 4f becomes the wedge element 2 in each case by 45 ° clockwise relative to the wedge element 1 twisted.

In the 5a to 5c is a schematic, partially perspective schematic representation ( 5b and 5c ) the rotation of the wedge-shaped elements 1 and 2 a further embodiment of a device according to the invention shown. The 5a to 5c show the twist of the wedge-shaped element 2 opposite the wedge-shaped element 1 (from 5a to 5b ), with subsequent twisting (from 5b to 5c ) of both wedge-shaped elements 1 and 2 common to the base 9 ,

The device after the 5a to 5c points between the base 9 and the functional area 1 of the wedge-shaped element 1 , between the storage area 1 of the wedge-shaped element 1 and the storage area 2 of the wedge-shaped element 2 , between the functional surface F2 of the wedge-shaped element 2 and the wing 10 each pivot bearing on. The relative position of the pivot bearing is chosen so that the axis of rotation of the bearing between the base 9 and the functional area 1 of the wedge-shaped element 1 , the axis of rotation of the bearing between the bearing surface 1 of the wedge-shaped element 1 and the storage area 2 of the wedge-shaped element 2 and the axis of rotation of the bearing between the functional surface F2 of the wedge-shaped element 2 and the wing 10 In this special case, for example, they intersect at one point (pole, rotating pole) of the functional surface.

Based on 5a to 5c it becomes apparent how the fall line (the one on the wing 10 drawn arrow) from the reference position at equal angles of α1 and α2 from the horizontal position between 90 ° and 180 ° with rotation of the wedge-shaped element 2 opposite the non-twisted wedge-shaped element 1 , emotional. With absolute rotation by 180 °, the fall line (the one on the wing 10 drawn arrow) by 90 ° so in each case by half the angular displacement of the wedge-shaped element 2 opposite wedge-shaped element 1 , If an alignment of the fall line (on the wing 10 drawn arrow) take place at a constant angle β1, so is the common rotation of the wedge-shaped element 1 and the wedge-shaped element 2 required. Here in the example ( 5c ) with a reverse rotation of -45 ° after the relative displacement ( 5b ) of + 90 ° of the wedge-shaped element 2 opposite to the wedge-shaped element 1 ,

The orientation of the 3-dimensionally dependent variable fall line (the one on the wing 10 drawn arrow) whose magnitude and direction from the relative displacement of the wedge-shaped element 2 opposite the wedge-shaped element 1 is clearly geometrically dependent - is required if the direction of the fall line (the one on the wing 10 drawn arrow) should meet certain requirements, as in a golf training device, at in which the inclined position of the standing surface on the function carrier can be aligned with respect to the direction of impact of the golf ball, eg in "hillside downwards" or "hillside upwards" or "lateral hillside upwards" or "lateral hillside upwards" or hybrid forms of said hillside locations, for example in an angle gauge , where the 3-dimensional device change is required for a 2-dimensional angle representation or an angle projection on a plane (2-dimensional).

The in the 5a to 5c illustrated embodiment is particularly advantageous usable, especially since the point referred to above as the pole or Drehpol quasi resting in all possible movements. This point can advantageously be used in particular to fasten devices at this point on the functional surface, for example for focusing devices, or target devices.

The Arrangement of the bearing must be with appropriate eccentricity to each other done so that this geometric requirement that all axes of rotation meet the axis intersections in one point, so that as far as possible prevents the function level in addition to the desired skew generation additionally makes a staggering movement.

In the in the 6a to 6c In the embodiment shown, the arrangement of the bearings is selected such that the point designated above as pole or rotary pole is definitely outside and / or above the functional plane. This is particularly advantageous in those applications that require a dormant point above the functional level, for example, devices with resting as possible "focus" or target locations (targets) which are targeted by laser, which then from different directions by operating the device with appropriately mounted Aiming at this point (pole, rotating pole) as a target, (target object) Applications can be made, for example, in medical technology or energy technology The advantageously variably selectable arrangement of the pivot bearings can, depending on requirements, be at certain points in the device Tumbling movements of the functional level prevented or defined generated and / or performed.
