Patent ID: 7270343

Claim:
Pivotable binding system ( 1 ) for mounting between a sports device ( 2 ) and a tread surface ( 5 ) for a user's foot, with which binding system ( 1 ) the tread surface ( 5 ) is pivotable about an axis extending almost parallel with the ankle joint of the foot and with which binding system ( 1 ) the tread surface ( 5 ) is displaceable in the front-part-region cooperating with the ball of the foot to a position closer to the sports device ( 2 ) by means of a rolling body ( 22 ) provided between the tread surface ( 5 ) and the sports device ( 2 ) in the region co-operating with the ball of the foot and forming a curved rolling surface ( 25 ; 26 ; 27 ) which supports the tread surface ( 5 ) at a vertical distance ( 24 ) above a top face ( 15 ) of the sports device ( 2 ), and which rolling surface ( 25 ; 26 ; 27 ) starts from a region of the tread surface ( 5 ) lying closer to the heel of a foot in a direction towards the toe region of the tread surface ( 5 ) and also curved downwards in a direction towards the top face ( 15 ) of the sports device ( 2 ), and having a binding element ( 11 ) that is flexible and resiliently deformable in a vertical plane ( 8 ), by means of which binding element ( 11 ) the tread surface ( 5 ) can be articularly joined to the sports device ( 2 ), and which flexible and resiliently deformable binding element ( 11 ) forms the pivotable connection between the tread surface ( 5 ) and the sports device ( 2 ), and with a lateral guide device ( 30 ) acting between the tread surface ( 5 ) and the rolling body ( 22 ) in order to prevent displacements in a direction perpendicular to the vertical plane ( 8 ) and to prevent twisting movements about an axis extending in a vertical direction between the tread surface ( 5 ) and the sports device ( 2 ).
