  • Patent number: 8419044
    Abstract: Winter sports gear, particularly an ice skate, include runners to which a sliding blade (3) is detachably connected. The sliding surface (1) of the sliding blade (3) is provided with at least one, in this case three, profiled grooves (4) that extend in the direction of travel. Bulge-type dams (5) extend on both sides of the profiled grooves (4).
    Type: Grant

  • Publication number: 20080150242
    Abstract: The invention relates to a skating sports device, in particular skating boot, comprising an exchangeable blade holder (14), connected to a boot by means of sole and heel plates (4 and 5). An exchangeable blade (1) may be clipped in the exchangeable blade holder (14), which is held under tension in the front and rear region by locking clip buttons (2) which may be operated without tools. A torsion duplex cross (3), formed by torsion and flexion bars (3a and 3b) absorbs the torsion and flexional forces occurring during skating and neutralizes the same.

  • Patent number: 5769434
    Abstract: A skating appliance or vehicle having a skate with a plastic base and a composite running blade exchangeably secured thereto. The exchangeable composite running blade is secured with the high resistance to torsion and flexure as well as high security against fracture, by means of an on edge mounted profiled stabilizing rail set into the lower side of the base, and easy to handle screwable holding members, and a corresponding design of the individual parts. These elements allow an arrangement to be obtained which as a whole has a low weight and a high resistance to pressure.
