Ice skate

An ice skate, particularly for speed skating comprising an upper half-frame having an articulation means for coupling to a foot support member which oscillates on a same plane with respect to a lower half-frame which is associated with a blade, comprising an articulation means which allows said upper half-frame to perform a forward translatory motion of a heel region and a backward translatory motion of a tip region, said upper half-frame comprising a substantially V-shaped bar having free ends, coupling means being provided at said free ends for coupling to a shoe, said coupling means comprising a pair of bases, said bases being arranged at the tip region and at the heel region, first slots being provided at the bases for connection to said foot support, said articulation means further comprising a first tab which protrudes at the end of said base that is arranged at a tip region, said first tab protruding in a downward direction and forwards with respect to said base, the tip of said first tab being freely pivoted, by means of a first pivot, at second slots formed at first shoulders which protrude upward and along planes which are parallel to a flat surface of said lower half-frame, said second slots having an arc-like shape, with a first end which is adjacent to said flat surface and with a second end which is further spaced from said flat surface, said second slots having a concavity directed toward the ice surface.
