Abstract

The invention describes a pivotable binding system (1) for mounting between a sports device (2) and a tread surface (5) for a user'"'"'s foot, in which the tread surface (5) is pivotable about an axis extending more or less parallel with the ankle joint of the foot and is displaceable, at least in a part region assigned to the toes, to a position closer to the sports device (2), and can be joined to the sports device by at least one binding element (11). The binding element (11) is flexible and is resiliently deformable in a vertical plane (8).

Claims

1-29. -29. (cancelled).

30. Pivotable binding system (1) for mounting between a sports device (2) and a tread surface (5) for a user'"'"'s foot, in which the tread surface (5) is pivotable about an axis extending almost parallel with the ankle joint of the foot and is displaceable, in at least one part region co-operating with the ball of the foot, to a position closer to the sports device (2), and having a binding element (11) that is flexible and resiliently deformable in a vertical plant (8), by means of which the tread surface (5) can be movably joined to the sports device (2), characterised in that a lateral guide device (30) is provided in order to prevent displacements in a direction perpendicular to the vertical plane (8) and twisting movements about an axis extending in a vertical direction between the tread surface (5) and the sports device (2).

31. Pivotable binding system as claimed in claim 30, characterised in that the lateral guide device (30) is provided as a groove-shaped recess (29) in the shoe sole (6) extending in a longitudinal direction—

double arrow (9)—

of the tread surface (5) and a projection (28) on the sports device (2) co-operating with this recess (29).

32. Pivotable binding system as claimed in claim 30, characterised in that 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, is immovably secured respectively to a shoe sole (6) forming the tread surface (5) and the sports device (2).

33. Pivotable binding system as claimed in claim 30, characterised in that in the end region (18) co-operating with the sports device (2), the binding element (11) is rigidly joined thereto and in the end region (17) co-operating with the tread surface (5) is joined to the latter by a hinge mechanism (45).

34. Pivotable binding system as claimed in claim 33, characterised in that an elastically resilient spring member co-operates 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.

35. Pivotable binding system as claimed in claim 30, characterised in that the binding element (11) is a leaf spring (12) made from an elastically resilient, metallic material.

36. Pivotable binding system as claimed in claim 30, characterised in that 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.

37. Pivotable binding system as claimed in claim 30, characterised in that between the shoe sole (6) and the sports device (2) in the region co-operating with the balls of the feet, a rolling body (22) is provided forming a curved rolling surface (25, 26, 27) and the rolling surface (25, 26, 27) is provided (6) on the rolling body (22) as a support for the shoe sole (6), extending in a substantially linear direction perpendicular to the vertical plant (8).

38. Pivotable binding system as claimed in claim 37, characterised in that the rolling body (22) supports the tread surface (5) for the foot or shoe sole (6) at a vertical distance (24) above a top face (15) of the sports device (2).

39. Pivotable binding system as claimed in claim 37, characterised in that the rolling surface (25, 26, 27) extends on the rolling body (22), starting from a region of the tread surface (5) lying closer to the heel, in a direction towards a toe region of the tread surface (5) and in a direction towards a running surface (10) or in a direction towards the top face (15) of the sports device (2) or moves closer to the latter.

40. Pivotable binding system as claimed in claim 37, characterised in that 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).

41. Pivotable binding system as claimed in claim 40, characterised in that 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).

42. Pivotable binding system as claimed in claim 40, characterised in that the rolling surfaces (25, 26) on either side of the centre rolling surface (27) form a slide track for the rolling movement of the shoe sole (6).

43. Pivotable binding system as claimed in claim 30, characterised in that 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).

44. Pivotable binding system as claimed in claim 30, characterised in that the tread surface (5) or the shoe sole (6) co-operates 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).

45. Pivotable binding system as claimed in claim 44, characterised in that the spring means (39) is a damping body (40) which is elastically flexible and resilient when pressure is applied, in particular made from an elastomeric synthetic material, in the toe region of the tread surface (5) between it and the sports device (2).

46. Pivotable binding system as claimed in claim 44, characterised in that the spring means (41) is a tension band (42) which is elastically flexible and resilient when subjected to tensile stress, in particular made from an elastomer synthetic material, and is arranged before the joining point, relative to the longitudinal direction (9) of the tread surface (5), between the binding element (11) and the shoe sole (6), being joined to the shoe sole (6) on the one hand and to the sports device (2) on the other.

47. Pivotable binding system as claimed in claim 30, characterised in that the return movement of the binding element (11) in a vertical direction starting from the sports device (2) is restricted by an anti-life mechanism (52) comprising a tension-resistant securing element (53) joined to the sports device (2) and the shoe sole (6).

48. Pivotable binding system as claimed in claim 30, characterised in that the deformability of the binding element (11) in the vertical plane (8) is restricted and may not be deformed in a vertical direction, starting from the sports device (2), beyond an initial shape or a shape in its rest state or beyond a substantially longitudinally extended configuration.

49. Pivotable binding system as claimed in claim 48, characterised in that the binding element (11) is a link strip having links which are able to pivot in a vertical direction starting from the sports device (2) and restricted by stops.

50. Pivotable binding system as claimed in claim 49, characterised in that the link strip can be displaced, starting from a longitudinally extended position, in a direction towards the sports device (2) to assume a curved position.
