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 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.

Abstract: A clap skate include a forefoot support which is adapted for fastening the sole portion of said skating shoe thereon. The forefoot support is pivotally connected to the front part of a skate frame about a transverse pivot pin, so as to allow said forefoot support with the skating shoe thereon to tilt about the pivot pin forwardly from a normal position, so that the skating shoe is lifted with its heel portion from the rear portion of the skate frame. The pivot pin is held between two bracket flanges extending upwardly from the front part of the skate frame. A spring mechanism tending to cause the forefoot support to return into the normal position comprises a U-shaped spring wire, the cross portion of which engages the upper face of the forefoot support and the legs of which are provided with a helically wound portion. The helically wound portions are each positioned around the pivot pin in an intermediary space between a flange and one lateral end of said forefoot support.

Abstract: A clap skate, including a frame having a forefoot support and a heel support, wherein said frame is pivotally connected to the forefoot support about a transverse pivot pin, which allows the frame to swing away from the heel, and wherein a spring is provided which causes the frame to return. The pivotable connection between the forefoot support and the frame is carried out as an adjustable friction swivel joint.
