Wheel, particularly for skates. Rollers and the like

Abstract

A wheel, particularly for skates, rollers and the like, comprising a rim ( 1 ), a tread ( 7 ) coupled to the rim and one or more anchoring elements ( 120 ), which project from the outer surface of the rim for improving the anchorage of the tread. The anchoring elements are located at least in a portion of the outer surface, which is closed to the outer edges of the outer surface.

1 . A wheel, particularly for skates, rollers and the like, comprising: a rim comprising a central hub and an outer rim connected with said central hub, said outer rim being provided with a substantially flat outer surface, which is delimited by a first outer edge and by a second outer edge; a tread coupled to said rim approximately at said outer surface; and one or more anchoring elements, which project from said outer surface for improving the anchorage of said tread to said outer rim, characterised in that said one or more anchoring elements are arranged, so as to be positioned at least on a portion of said outer surface, which is substantially close to said first outer edge and/or to said second outer edge.  
     
     
         2 . The wheel according to  claim 1 , characterised in that said outer surface comprises a first side surface portion and a second side surface portion, which are positioned close to said first outer edge and said second outer edge, said first side surface portion and a second side surface portion being externally delimited by said first outer edge and said second outer edge, respectively; and a middle surface portion substantially comprising a middle plane, which intersects perpendicularly said outer surface and which is equally spaced from said first outer edge and said second outer edge, said middle surface portion being delimited by said first side surface portion and a second side surface portion.  
     
     
         3 . The wheel, according to the preceding claims, characterised in that said one or more anchoring elements project from said outer surface approximately at said first side surface portion and/or at said second side surface portion.  
     
     
         4 . The wheel according to  claim 2 , characterised in that said one or more anchoring elements project from said outer surface approximately at said first outer edge and/or at said second outer edge, so as to substantially lie on the same plane of said first outer edge and/or of said second outer edge.  
     
     
         5 . The wheel according to one or more of the preceding claims, characterised in that said one or more anchoring elements comprise two or more ring-like ribs, which project radially from said outer surface.  
     
     
         6 . The wheel according to  claim 5 , characterised in that said ring-like ribs are parallel and equally spaced apart one another and are arranged in pairs in a symmetrical position with respect to said middle plane.  
     
     
         7 . The wheel according to one or more of the preceding claims, characterised in that said one or more anchoring elements comprise one or more lugs, which project radially from said outer surface.  
     
     
         8 . The wheel according to  claim 7 , characterised in that said one or more lugs comprise a pair of lateral parallel lugs, which project radially from said first side surface portion and from said second side surface portion and an intermediate central lug, which projects radially from said middle surface portion.  
     
     
         9 . The wheel according to  claim 8 , characterised in that said intermediate central lug is provided with a reduced height and/or a reduced length in comparison with said lateral parallel lugs.  
     
     
         10 . The wheel according to one or more of the preceding claims, characterised in that said one or more anchoring elements comprise one or more projections, which project radially from said outer surface.  
     
     
         11 . The wheel according to  claim 10 , characterised in that said one or more projections are arranged in pairs according to a staggered layout.  
     
     
         12 . The wheel according to one or more of the preceding claims, characterised in that said rim is obtained, at least partially, by way of an extrusion process.
