Abstract: Connecting mechanisms for pivotally coupling a shoe with a sporting device are described. In one embodiment, the connecting mechanism can include a support element for supporting a shoe, a connecting element disposed on a sporting device, and a coupling element for coupling the support element to the connecting element. The support element can include a first end liftably disposable on the sporting device and a second end spaced apart from the first end. The coupling element can include a first end attachable via a first pivot to the second end of the support element and a second end attachable via a second pivot to the connecting element. The first and second pivots can be active successively with the progression of a bending movement of a foot in a shoe supported by the support element.

Abstract: A connecting body for bone pieces to be joined together, characterized in that it has turned ends at both sides of a substantially elongated which may be completely driven into the bone pieces to be joined. At least one side of the body between the ends is preferably provided with a sharp edge. The body is preferably provided with at least one tooth pointing sideways and projecting away from the sharp edge.

Abstract: A connecting organ for coupling a shoe with a sporting device such as a skate or a roller skate, ski or the like, such as to be pivotable around a pivoting point, which is equipped with a first and a second pivoting point which during use are successively active with a progression of a foot's bending. the shoe can be mounted onto a support element which at a first end thereof liftably rests upon the sporting device and at a second end removed from the first end is via the first pivoting point connected with an end of a coupling element whose other end is connected via the second pivoting point with a connecting organ that is mounted on the sporting device.
