Abstract:
1. A skate frame comprising: a lower frame portion comprising gliding means for running on a gliding surface, said lower frame portion comprising one or more first protruding arms, which are directed upwardly with respect to said gliding means, said first protruding arms comprising one or more first coupling surfaces; and an upper frame portion comprising one or more support surfaces for supporting the user's boot, said upper frame portion comprising one or more second protruding arms, which are directed downwardly with respect to said support surfaces, said second protruding arms comprising one or more connection channels that accommodate at least partially said first protruding arms and mechanically couple with said first coupling surfaces, a mutual interlock between said first coupling surfaces and said second coupling surfaces preventing relative movements between the upper frame portion and the lower frame portion of said skate frame at least along a first reference axis (X) that is substantially parallel to said gliding surface and a second reference axis (Y) that is substantially parallel to said gliding surface, wherein said first reference axis (X) substantially corresponds to a rearward-forward longitudinal axis of said skate frame and said second reference axis (Y) substantially corresponds to a side-to-side transversal axis of said skate frame; wherein the upper frame portion of said skate frame comprises a toe member and a heel member, which are separated from each other, said toe member comprising one or more toe second protruding arms, which are directed downwardly with respect to a toe support surface of said toe member, said toe second protruding arms comprising one or more toe second coupling surfaces that mechanically couple with the toe first coupling surfaces of said toe first protruding arms, said heel member comprising one or more heel second protruding arms, which are directed downwardly with respect to a heel support surface of said heel member, said heel second protruding arms being shaped so as to define one or more heel connection channels, said heel connection channels comprising one or more heel second coupling surfaces that mechanically couple with the heel first coupling surfaces of said heel first protruding arms; and wherein a plurality of said heel first protruding arms are reciprocally angled, so that the mutual interlock between said heel first coupling surfaces and said heel second coupling surfaces prevent relative movements between the heel member of said upper frame portion and the heel section of said lower frame portion also along a third reference axis (Z) that is substantially perpendicular to said gliding surface, when the user′ a user's boot is operatively connected to said toe member and said heel member.
