Another component of the adjustment device according to the invention is a Intermediate plate 6. The intermediate plate 6, the top and bottom of which in Fig. 9a and Fig. 9b is essentially rectangular in shape and has edge regions 6a provided, which can be inserted into the edge strips 1a. The intermediate plate 6 is thus slidably arranged on the rail 1. The intermediate plate 6 is with a Raised cylindrical area where a circular opening 6b is formed whose diameter is adapted to the diameter of the control disk 4 so that it can be inserted from below into the opening 6b. The tax rates 4c come into contact with a control curve 16, which is located on one within the Opening 6b circumferential heel surface is formed. The along each of Semicircular control curves 16 have a special design which will now be discussed in more detail below with reference to FIGS. 9b and 9c. In their starting position, the control lugs 4c of the control disk 4 are on horizontal seating surfaces limited laterally by downwardly projecting stops 26 16a. This position corresponds to the lowest position of the control disc 4 and also completely locked position. The stops 26 allow the Control disc 4 only in one direction, here only clockwise. To each of these Seat surfaces 16a adjoins a control surface 16b which rises in two sections and which at a higher level passes into a second seat 16c. Another one increasing control surface 16d eventually becomes a third level with a third Seat 16e reached. The interaction of the control disk 4 with the control curve 16 of the intermediate plate 6 is explained in more detail below.

Circular depressions 6c are formed on the upper side of the intermediate plate 6, each for receiving and supporting the one end area Helical compression spring are provided. These feathers are in the drawing figures not shown. The helical compression springs are supported with their second ends the underside of an intermediate ring 15, the configuration of which is shown in particular in FIG. 10 shows.

The intermediate ring 15 has an outer edge region 15b, on the underside thereof In a slightly inclined arrangement, a toothing 15a extends in a ring. This Tooth 15a consists of a series of many similar teeth that extend virtually radially, based on the center of the intermediate ring 5. To the outer edge region 15b adjoins a pronounced depression 15c, which for Recording the actuating disc 7 is provided. The recess 15c is in the middle with an opening 15d through which the central cylindrical extension part 7a Actuating disc 7 is guided. The intermediate ring 15 also has on its underside two diametrically opposite and approximately rectangular in cross section Locking projections 15f, which in elongated locking openings 16e, in the intermediate plate 6 are designed to intervene. At the bottom of the intermediate ring 15 are also two lateral support lugs 15e are provided, which have a certain longitudinal extent own and lie in the area of the step surfaces 13a of the base plate 3 and the Guide binding base plate 20 laterally.

As shown in FIG. 1, the binding base plate 20 has a in its central region Provide opening 20a for receiving the components of the adjusting device. The circular opening 20a is centered in one from the top of the binding base plate 20 offset, also circular recess formed, the Opening 20a from a circular shoulder at the lower level is circulated where a toothing 23 is formed, which the counter toothing to Represents teeth 15a on the intermediate ring 15. The actuating disc 7 is under Interposition of the intermediate ring 15 in the central opening 20a Binding base plate 20 is used and is here on the intermediate plate 6, wherein the ring-shaped circumferential teeth 13a on the intermediate ring 15 with the Counter toothing 23 is engaged on the binding base plate 20. In the Starting position - the locked and unactuated position - is the locking part 5a of the locking pin 5 locked in one of the holes 2a of the row of holes 2 and the Control lugs 4c of the control disk 4 sit on the seat surfaces 16a of the control curve 16th

The functioning of the adjustment device according to the invention is as follows. To a Twisting the binding base plate 20 and thus the snowboard binding perform the snowboard, the operating bracket 10 by hand superscript and a rotary movement of the actuating bracket 10 Actuating disc 7 initiated clockwise. The with the operating disc 7th connected control disk 4 moves with its control lugs 4c along the first control surfaces 16a, whereby under the pressure of the, not shown, the Intermediate ring 15 springs acting from below, the teeth 15a of the Intermediate ring 15 out of engagement with the teeth 23 on the binding plate 20th comes. The locking pin 5 is raised slightly, but it remains in the hole 2a Row of holes 2 locked. The intermediate ring 15 is lifted, but his Locking projections 15d keep their engagement in the locking openings 16e. The Binding base plate 20 can be rotated as desired, after reaching the desired position of the actuating bracket 10 or the actuating disc 7 in opposite direction is turned back, creating an opposite movement of the components involved and the two toothings 15a, 23 together come back into engagement. When turning the actuating disc 7 over the Actuating bracket 10 is the one that reaches defined seating surfaces 16a, 16c Control approaches 4c reaching the desired positions - possibility to Twisting, reaching the locked position - clearly noticeable.

If the snowboard binding is to be adjusted lengthways compared to the snowboard, so the actuating disc 7 is rotated somewhat further via the actuating bracket 10, so that the control surfaces 16d also come into effect. Under the pressure of the Intermediate ring 15 springs act on the on the control surfaces 16d sliding control approaches 4c lifting the actuating disc 7 together with the Intermediate ring 15 and also the locking bolt 5 connected to the control disk 4. As a result, the locking part 5a of the locking pin 5 is disengaged from the hole 2a in the Row of holes 2. The intermediate ring 15 remains on its locking projections with the Intermediate plate 6 connected. Now the binding base plate 20 together with all components are moved to the desired position and twisted the actuating disc 7 locked in the opposite direction in this position become. Since the binding base plate 20 is also released for a rotary movement attention must be paid to the desired rotational position of the same. The Incidentally, spring loading of the locking pin 5 ensures that this - if necessary with a slight push on the binding - again engages in a hole 2a of the row of holes 2.

It should be mentioned that the dimensioning of the teeth of the gears is the delicacy of the Rotation adjustment can be determined and selected accordingly. Where it is is desired, can also stop on individual components of the device Limitation of movements can be provided. The concerned Dimensional frames are familiar to a specialist and are therefore not separately described. The individual components of the adjustment device can also consist either of plastic or of metal, with the expert here too knows which material should be selected for which component.
