Hockey ice skate

Abstract

An ice skate comprising a blade and a chassis, the chassis being associated with the blade along one side of it, to support and apply the blade to the sole of a shoe for ice skates, wherein the chassis has a box structure, substantially a shell, made by at least one layer of prefixed material and including the blade at said one side, with a hard clamping of the blade between the sides of the shell structure so as to substantially realize a keel for the blade.

         2 . The ice skate of  claim 1 , wherein the chassis is made by at least three layers, with the formation of a multilayer composite which realizes the box structure. 
     
     
         3 . The ice skate of  claim 2 , wherein the multilayer composite includes an inner layer and an outer layer which are made of resin reinforced with carbon fibers and an intermediate layer comprising Kevlar or the like. 
     
     
         4 . The ice skate of  claim 3 , wherein the intermediate layer is made by Kevlar and a resin reinforced with carbon fibers. 
     
     
         5 . The ice skate of  claim 4 , wherein the materials of the layers are woven. 
     
     
         6 . The ice skate of  claim 5 , wherein the multilayer composite comprises different layers and a resin, the resin acting as an adhesive. 
     
     
         7 . The ice skate of  claim 6 , wherein the blade comprises at least one recess in correspondence with said one side, the recess defining an undercut surface being engaged with the multilayer composite to positively hold the blade. 
     
     
         8 . The ice skate of  claim 6 , wherein the blade comprises at least two recesses in correspondence with said one side, the recesses being symmetrically placed at the front and rear ends of the blade and defining respective undercut surfaces being engaged with the multilayer composite to positively hold the blade. 
     
     
         9 . The ice skate of  claim 1 , wherein the chassis comprises a front portion and a rear portion having respective free edges being bordered with respective flanges configured to fix the chassis to the sole of the shoe. 
     
     
         10 . The ice skate of  claim 9 , wherein the chassis comprises an intermediate portion between the front and rear portions, the intermediate portion having a zone intended for receiving a visual communication. 
     
     
         11 . The ice skate of  claim 9 , wherein the chassis comprises a lowered intermediate portion between the front and rear portions, the lowered intermediate portion defining an air zone between the chassis and the sole of the shoe. 
     
     
         12 . The ice skate of  claim 11 , wherein the chassis further comprises a closing element between the front and rear portions, the closing element having a matching profile with respect to a perimeter of the air zone. 
     
     
         13 . The ice skate of  claim 3 , wherein the multilayer composite comprises at least a thermoplastic or elastomeric material. 
     
     
         14 . The ice skate of  claim 12 , wherein the multilayer composite comprises an inner layer made by a thermoplastic or elastomeric material and the closing element is thermowelded to the inner layer. 
     
     
         15 . An ice skate shoe comprising a sole, a blade and a chassis, the chassis being associated with the blade along one side of it, to support and apply the blade to the sole, wherein the chassis has a box structure, substantially a shell, made by at least one layer of prefixed material and incorporating the blade at said one side, with a hard clamping of the blade between sides of the shell structure so as to substantially realize a keel for the blade. 
     
     
         16 . The ice skate shoe of  claim 15 , wherein the chassis is made by at least three layers, with the formation of a multilayer composite which realizes the box structure. 
     
     
         17 . The ice skate shoe of  claim 16 , wherein the multilayer composite includes an inner layer and an outer layer which are realized of resin reinforced with carbon fibers and an intermediate layer comprising Kevlar or the like. 
     
     
         18 . The ice skate shoe of  claim 16 , wherein the blade comprises at least one recess in correspondence with said one side, the recess defining an undercut surface being engaged with the multilayer composite to positively hold the blade. 
     
     
         19 . The ice skate shoe of  claim 15 , wherein the chassis comprises a front portion and a rear portion having respective free edges being bordered with respective flanges to their fixing to the sole. 
     
     
         20 . The ice skate shoe of  claim 19 , wherein the chassis comprises a lowered intermediate portion between the front and rear portions, the lowered intermediate portion defining an air zone between the chassis and the sole of the shoe. 
     
     
         21 . The ice skate shoe of  claim 20 , wherein the chassis further comprises a closing element between the front and rear portions, the closing element having a matching profile with respect to the perimeter of the air zone. 
     
     
         22 . An ice skate, comprising:
 a shoe having a sole;   a blade having an upper portion with a protruding portion defining an underlying recessed area; and   a chassis configured to fix the blade to the sole of the shoe, the chassis including a recessed portion configured to receive and clamp the upper portion of the blade and an undercut surface configured to extend into the underlying recessed area of the blade and engage the protruding portion of the blade.
