Pivotable binding system as claimed in claim 1, wherein the binding element (11) is strip-shaped but resistant to expansion and shrinkage and, at end regions (17, 18) spaced apart from one another in the longitudinal direction (9) of the tread surface (5) for the foot, and is immovably secured respectively to (i) a shoe sole (6) forming the tread surface (5) and to (ii) the sports device (2). 4. Pivotable binding system as claimed in claim 1, wherein the binding element (11) in the end region (18) cooperates with the sports device (2 ) and is rigidly joined thereto and the binding element (11) in the opposite end region (17) cooperates with the tread surface (5) and is joined to the latter by a hinge mechanism (45). 5. Pivotable binding system as claimed in claim 4, wherein an elastically resilient spring member cooperates with the hinge mechanism (45) pivotably joining the shoe sole (6) to the binding element (11), in particular in the form of a torsion spring, which applies a mechanical resistance against the upward pivoting movement of the tread surface (5) relative to the sports device (2), which can be overcome by the user's foot. 6. Pivotable binding system as claimed in claim 1, wherein the binding element (11) is a leaf spring (12) made from an elastically resilient, metallic material. 7. Pivotable binding system as claimed in claim 1, wherein the binding element (11) is a strip which is resistant to expansion and substantially to shrinkage but which is resiliently deformable and flexible in a direction perpendicular to the two broad sides (13, 14) thereof. 8. Pivotable binding system as claimed in claim 1, wherein the rolling body (22) has at least three rolling surfaces (25, 26, 27) spaced at a distance from one another, the top rolling surface (27) in the height direction forming a predefined rolling path for the binding element (11) when the tread surface (5) is pivoted upwards relative to the sports device (2) and the rolling surfaces (25, 26) lying lower than the top rolling surface (27) and disposed on either side of the top rolling surface (27) are designed to roll the toe region of the shoe sole (6) in a direction towards the sports device (2) when the shoe sole (6) is pivoted upwards relative to the sports device (2). 9. Pivotable binding system as claimed in claim 8, wherein the centre rolling surface (27) on the rolling body (22) forms a slide track for the leaf-spring binding element (11) and side faces (31, 32) of the projection (28) on the rolling body (22) are designed to abut largely without any clearance with side walls (33, 34) of the groove-shape recess (29) in the shoe sole (6) to form the lateral guide device (30). 10.

Pivotable binding system as claimed in claim 1, wherein a deformation resistance perpendicular to the broad sides (13, 14) of the binding element (11) is dimensioned so as to be greater than a gravitational force acting on the binding element (11) through the sports device (2). 12. Pivotable binding system as claimed in claim 1, wherein the tread surface (5) or the shoe sole (6) cooperates with an elastically resilient spring means (39, 41) which forces the tread surface (5) into a position extending almost parallel with the sports device (2). 13.
