In this case, the angle between the functional surface F1 of the wedge element 1 and the functional surface F2 of the wedge element F2, in the present case the angle β1, is adjustable. In the arrangement of the two shown in Fig. 1a Wedge elements 1 and 2 to each other extend the functional surfaces F1 and F2 of the wedge elements 1 and 2 parallel to each other. By turning the wedge element 2 relative to the wedge element 1, the functional surface F2 can be tilted by the angle β1 relative to the functional surface F1. In Fig. 1 b, the wedge member 2 is rotated relative to the wedge member 1 by 180 ° and, accordingly, the angle ß1 between the functional surface F1 of the wedge member 1 and the functional surface F2 of the wedge member 2 occupied.

The functional surface F3 is arranged on the substrate and the functional surface F4 forms the support surface or a support for the support surface. The wedge-shaped elements 3 and 4 are presently formed as wedge stumps 3 and 4, wherein between the bearing surfaces L3 and L4 and the functional surfaces F3 and F4 of the wedge stumps 3 and 4 respectively the angle α3 or α4, in the present case about 18 °, is given. By appropriate rotation of the truncated wedge 4 with respect to the truncated cone 3, the position of the functional surface F4 of the truncated cone 4 relative to the functional surface F3 of the truncated cone 3 can be changed in the present case. The change in the position of the functional surface F4 relative to the functional surface F3 is effected by a change in the angle between the functional surface F3 and the functional surface F4, in this case the angle ß2 in Fig. 2b.

In the embodiment of a device for providing two functional surfaces F5 and F8 shown in FIGS. 3a and 3b, four wedge-shaped elements in the form of wedges 5, 6, 7 and 8, which are arranged rotatably on one another, are used. The functional surface F5 is arranged on the substrate 9 and the functional surface F8 forms a support for the support surface 10. The wedges 5 and 6 are presently formed at an angle α5 and α6 of about 18 °, while the wedges 7 and 8 an angle α7 or have α8 of about 9 °. The functional surface F5 of the wedge 5 is in the present case rotatably mounted on the floor or a base surface 9. The functional surface F8 of the wedge 8 serves in the present case as a support for a support surface 10 mounted on a bearing 11. By turning the wedges 6 and 8 relative to the wedges 5 and 7, the device is shown in FIG. 3a from that shown in FIG Location be brought, wherein between the functional surfaces F5 of the wedge 8 and the functional surface F8 of the wedge 8, the angle ß3 is taken. In FIGS. 4a to 4f, the stepwise rotation of the wedge element 2 relative to the wedge element 1 is shown in a schematic representation. The degree display shown above the wedge element 2 indicates the stepwise rotation of the wedge element 2. The degree indication indicated below the wedge element 1 indicates the rotation of the wedge element 1. In the present case, that of the wedge element 1 is not twisted. In the present case, a rotation of the wedge element 2, starting from the position shown in Fig. 4a by 360 ° in the position shown in Fig. 4f, corresponding to a full rotation of the wedge element 2. In the individual steps of Fig. 4a of Fig. 4b, of FIG 4b according to FIG. 4c, from FIG. 4c to FIG. 4d, from FIG. 4d to FIG. 4e and from FIG. 4e to FIG. 4f, the wedge element 2 is rotated in each case by 45 ° in the clockwise direction relative to that of the wedge element 1.

FIGS. 5a to 5c show in a schematic, partially perspective schematic illustration (FIGS. 5b and 5c) the rotation of the wedge-shaped elements 1 and 2 of a further embodiment of a device according to the invention. 5a to 5c show the rotation of the wedge-shaped element 2 with respect to the wedge-shaped element 1 (of Fig. 5a of FIG. 5b), with subsequent rotation (of Fig. 5b of FIG. 5c) of both wedge-shaped elements 1 and 2 together opposite the base 9.

The device according to FIGS. 5 a to 5 c has between the base 9 and the functional surface 1 of the wedge-shaped element 1, between the bearing surface 1 of the wedge-shaped element 1 and the bearing surface 2 of the wedge-shaped element 2, between the functional surface F 2 of the wedge-shaped element 2 and the Wing 10 each pivot bearing on. The relative position of the pivot bearing is selected so that the axis of rotation of the bearing between the base 9 and the functional surface 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 bearing surface 2 of the wedge-shaped element 2 and the axis of rotation of Bearing between the functional surface F2 of the wedge-shaped element 2 and the support surface 10 in this special case approximately at a point (pole, Drehpol) intersect the functional surface.

With reference to FIGS. 5a to 5c, it can be seen how the falling line (the arrow drawn on the support surface 10) from the reference position with angular equality of α1 and α2 from the horizontal position between 90 ° and 180 ° with rotation of the wedge-shaped element 2 against the not twisted wedge-shaped element 1, emotional. In absolute as well as relative rotation by 180 ° of the wedge-shaped element 2 with respect to the first non-twisted (blocked) element 1, the fall line of the support surface (represented on the support surface 10 by an arrow) moves in the same direction of rotation by 90 °, respectively half of the relative angular displacement of the wedge elements (wedge-shaped element 2 with respect to wedge-shaped element 1) The consideration of this relationship is included in the inventive idea compared to the prior art, in particular by the arrangement of an independently rotatably mounted on the wedge element 2 support surface 10 or a used independently rotatably mounted functional element, in order to ensure in case of three-dimensionally variable fall line, which characterizes the tilt of the functional surface, the alignment stability and the orientation independence of the support surface 10 about its axis of rotation line (the arrow drawn on the support surface 10) take place at a constant angle ß1, so the common rotation of the wedge-shaped element 1 and the wedge-shaped element 2 is required. Here in the example (Fig. 5c) with a reverse rotation of -45 ° after the Relatiwerschiebung (Fig. 5b) of + 90 ° of the wedge-shaped element 2 with respect to the wedge-shaped element. 1

The orientation of the 3-dimensionally dependent variable fall line (the arrow drawn on the support surface 10) whose magnitude and direction is clearly geometrically dependent on the relative displacement of the wedge-shaped element 2 with respect to the wedge-shaped element 1 is required if the direction of the fall line (the on the support surface 10 drawn arrow) should meet certain requirements, such as in a golf practice device, in which the skew of the floor space on the function carrier against the direction of the golf ball can be aligned, eg in "hillside downhill" or "hillside up" or "lateral hillside up" or "lateral hillside up" or hybrid forms of said slopes. For example, in an angle gauge, where the 3-dimensional device change for a 2-dimensional angle representation or an angle projection on a level (2-dimensional) is required.

The embodiment shown in FIGS. 5a to 5c can be used particularly advantageously, in particular since the point designated above as the pole or the rotating pole virtually rests in all possible movements. This point can advantageously be used in particular to attach devices at this point on the functional surface, for example, for focusing devices, or target devices.

The arrangement of the bearings must be done with appropriate eccentricity to each other, so that this geometric requirement that meet all axes of rotation of the axial intersections in one point, so that is largely prevented that performs the function level in addition to the desired skew production additionally a tumbling movement.

In the embodiment illustrated in FIGS. 6a to 6c, 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.
