Skate structure with one-piece frame

Abstract

A skate structure, particularly a roller skate with in-line wheels, comprising a frame ( 10 ) for supporting the wheels ( 14 ), a rigid sole ( 16 ) for supporting a first shoe body ( 30 ), a rigid cradle ( 34 ) for lateral and rear support of said first shoe body ( 30 ), an oscillating collar ( 40 ) for supporting the user's leg, and a removable, soft second shoe body ( 50 ) inserted into the said first shoe body ( 30 ) and designed to hold the user's foot. The frame ( 10 ), the rigid sole ( 16 ) and the rigid support structure ( 34 ) constitute an integral structure made in a single piece. A rigid toe-piece ( 18 ) may also be part of the one-piece structure, or, alternatively, may be produced as a separate component to be attached to the first shoe body ( 30 ′) or to the one-piece structure before final assembly of the skate.

1 . Skate structure, particularly a roller-skate with in-line wheels, comprising a frame for supporting the wheels, a rigid sole for supporting a first shoe body, a rigid cradle for lateral and rear support of said first shoe body, a collar for supporting the user's leg, and a removable, soft second shoe body inserted into the said first shoe body and designed to hold the user's foot, characterised in that said frame, said rigid sole and said rigid cradle are an integrally formed structure made in one piece, and said first shoe body is permanently fastened to said rigid sole.  
     
     
         2 . Skate structure according to  claim 1 , comprising a rigid toe-piece integral with said rigid sole and placed at the front of said structure, designed to be functionally coupled to the front portion of said first shoe body, characterised in that also said toe-piece is integrally formed with said sole, said frame and said cradle, thereby forming a single piece.  
     
     
         3 . Skate structure according to  claim 1 , characterised in that said first shoe body includes a rigid toe-piece and the unit formed by said first shoe body and said rigid toe-piece is fixed to said one-piece structure comprising said frame, said rigid sole and said support structure.  
     
     
         4 . Skate structure according to  claim 3 , characterised in that said unit comprising said first shoe body and said rigid toe-piece is fixed to said one-piece structure by adjustable fastening means.  
     
     
         5 . Skate structure according to  claim 1 , characterised in that it also comprises a rigid toe-piece made as a separate component, designed to be functionally coupled to said one-piece structure or to said first shoe body before final assembly of the skate structure.  
     
     
         6 . Skate structure according to  claim 1 , characterised in that said first shoe body is formed with an upper edge cut at the rear towards the bottom, said rigid cradle has side openings in a position corresponding essentially to the user's ankles, and said second shoe body has semi-rigid cushioning pads in a position corresponding to said openings on said rigid cradle, said semi-rigid cushioning pads being engaged in said openings as a means of fixing said second shoe body to said rigid cradle and thus to said one-piece structure.  
     
     
         7 . Skate structure according to  claim 1 , characterised in that said collar is pivotally fixed to said rigid cradle by means of pins on the upper part of each side of said cradle.
