A binding unit for a snowboard that permits an individual adjustment of angular position relative to the snowboard, includes, for fixing it to the snowboard, a substantially circular retaining disc, as seen in plan view, for a base plate of relatively large surface area. Coupling parts are mounted directly or indirectly on the base plate to provide a connection to a snowboard shoe which is releasable from the snowboard when the coupling parts are inactive or deactivated. At least one slide element on the retaining disc is displaceable between an extracted position, in which the at least one slide element at least partially covers the base plate, a portion of the slide element or elements projecting from a circular circumferential region of the retaining disc in the extracted position, and an inserted position, in which the at least one slide element does not at least partially cover the base plate.

What is claimed is: 1. Binding unit for a snowboard that permits an individual adjustment of angular position relative to the snowboard, comprising, for the purpose of fixing it to the snowboard, a retaining disc, which is substantially circular as seen in plan view, for a base plate of relatively large surface area, wherein there are at least three different angular positions of the base plate to the retaining disc; wherein, when the angular position of the base plate is changed, the retaining disc remains rigidly joined to the snowboard by means of fixing screws; and wherein the retaining disc is fixed in a fixed angular position on the snowboard; coupling parts mounted directly or indirectly on the base plate to provide a connection to a snowboard shoe, which snowboard shoe is releasable from the snowboard when the coupling parts are inactive or deactivated, and at least one slide element supported on the retaining disc, the at least one slide element being displaceable between an extracted position, in which the at least one slide element at least partially covers the base plate, a portion of the at least one slide element projecting from a circular circumferential region of the retaining disc in the extracted position, and an inserted position, in which the at least one slide element does not at least partially cover the base plate, the at least one slide element having an inclined surface in an end region next to the base plate, running at an angle to a standing plane of the base plate for enabling the retaining disc to be connected to the base plate in an arrangement that is as clearance-free as possible; wherein an adjusting mechanism with a handle designed to manually adjust several of said slide elements synchronously in opposite directions, and thereby the slide elements are coupled in their displacement; wherein the handle is also used for a release and locking mechanism for manually, selectively releasing and locking displacement of the at least one slide element. 2. Binding unit according to claim 1, comprising at least two of said slide elements displaceably mounted on the retaining disc in a diametrically opposite arrangement or distributed around the circular circumferential region. 3. Binding unit according to claim 1, wherein the at least one slide element is displaceable at least substantially radially to the retaining disc. 4. Binding unit according to claim 1, wherein the adjusting mechanism is a pinion or driving gear disposed at the center of the retaining disc and drivingly connected to the slide elements. 5. Binding unit according to claim 1, wherein the retaining disc is a gear with teeth on its end face. 6. Binding unit according to claim 1, the retaining disc being inserted in a central orifice of the base plate such that the perimeter of the retaining disc does not extend beyond a perimeter of the central orifice, and comprising teeth between the base plate and the retaining disc, the teeth securely fixing selectively adjustable and fixable angular positions between the retaining disc and the base plate. 7. Binding unit according to claim 6, wherein the teeth comprise straight teeth on the retaining disc and on the base plate inside the orifice for receiving the retaining disc. 8. Binding unit according to claim 7, wherein, when the retaining disc is inserted in the base plate, the corresponding teeth form a mutual anti-rotation lock relative to their mounting plane. 9. Binding unit according to claim 1, wherein the at least one slide element in the extracted position prevents the base plate from being lifted off the retaining disc in a direction perpendicular to its mounting plane while enabling the base plate to be lifted off the retaining disc in the inserted position. 10. Binding unit according to claim 1, wherein the release and locking mechanism is designed to securely fix the at least one slide element in the extracted position. 11. Binding unit according to claim 1, wherein the release and locking mechanism is designed to selectively release and lock the rotating motion of a pinion or driving gear for the slide elements. 12. Binding unit according to claim 11, wherein the release and locking mechanism comprises an operating handle for rotating the pinion or driving gear. 13. Binding unit according to claim 12, wherein the handle is pivotable about an axis aligned parallel with a standing plane for the sports shoe, between a non-operating position in which it lies in the standing plane and an active position folded out from the standing plane. 14. Binding unit according to claim 13, wherein, in the non-operating position, the handle forms an anti-rotation lock for the pinion. 15. Binding unit according to claim 1, wherein the retaining disc constitutes a pre-assembled unit with the snowboard. 16. Binding unit according to claim 1, comprising inclined surfaces extending at an angle to the standing plane in a peripheral region around the orifice in the base plate. 17. Binding unit according to claim 1, wherein the retaining disc has guide elements for linearly guiding the at least one slide element. 18. Binding unit according to claim 1, comprising at least one positive connector on a bottom face of the retaining disc for establishing a positive connection with a corresponding connector on the top face of the snowboard. 19. Binding unit according to claim 18, wherein the positive connector of the retaining disc in conjunction with the corresponding or complementary shaped connector on the snowboard form a guide arrangement that is lockable and releasable to permit a relative adjustment of the binding unit in the longitudinal direction of the snowboard. 20. Binding unit according to claim 18, wherein the positive connector of the retaining disc is at least one projection standing proud of its bottom face which can be selectively displaced and fixed in at least one guide groove provided in the top face of the snowboard. 21. Binding unit according to claim 18, wherein, when the at least one slide element is in the extracted position via inclined surfaces between co-operating contact surfaces between the positive connector, a clamping or retaining force is produced, which is sufficient to prevent a free or undesired relative displacement of the retaining disc or the entire binding unit in the direction of the longitudinal axis of the snowboard. 22. Binding unit according to claim 18, wherein the positive connector permits a slight vertical displacement of the retaining disc relative to the top face of the snowboard when the at least one slide element is in the inserted position. 23. Binding unit according to claim 1, comprising an anti-liftoff restriction on the retaining disc, which enables the base plate to rotate when lifted off the snowboard but prevents the base plate from being totally removed from the retaining disc. 24. Binding unit according to claim 20, wherein the at least one projection permits a relative displacement of the retaining disc or the entire binding unit in the longitudinal direction of the snowboard due to a slight vertical clearance when the at least one slide element is in the inserted position.
