Slip-proof cover for vehicle tyres

Abstract

Slip-proof cover for vehicle tyres for use in adverse weather conditions, preferably snow or ice, with a configuration that allows a simple mounting. The cover is highly reliable and positionally stable, and has a good mechanical performance with respect to abrasion. The cover has a structure and composition of the cut swath that optimise its slip-proof characteristics and its resistance to abrasion.

1 . Slip-proof cover for vehicle tyres characterised in that it is constituted by a textile fabric ( 1 ) made of high-tenacity cords spun with several strands and with a textile ligament, producing a fabric with a surface density of 0.3 to 1 Kg/m 2 , this fabric being used to constitute the main band ( 1 . 1 ) with an orientation (α) of the fibres from 45° to 90°, and a width greater than the width of the tyre provided at its sides with corresponding elastic adjusting straps ( 2 ,  3 ) that are fitted on either side of the tyre.  
     
     
         2 . Slip-proof cover for vehicle tyres according to  claim 1  characterised in that the orientation angle (α) of the fibres is 45° plus/minus 10°.  
     
     
         3 . Slip-proof cover for vehicle tyres according to  claim 1  characterised in that the textile ligament is taffeta.  
     
     
         4 . Slip-proof cover for vehicle tyres according to  claim 1  characterised in that the cord formed by the fabric ( 1 ) comprises 5 to 9 strands.  
     
     
         5 . Slip-proof cover according to  claim 1  characterised in that the cord that forms the fabric ( 1 ) has different thickness, so that the main band ( 1 . 1 ) has irregularities.  
     
     
         6 . Slip-proof cover for vehicle tyres according to  claim 1  characterised in that the fabric is polypropylene.  
     
     
         7 . Slip-proof cover for vehicle tyres according to  claim 1  characterised in that the fabric is para-aramid.  
     
     
         8 . Slip-proof cover for vehicle tyres according to  claim 1  characterised in that the cord that forms the textile fabric ( 1 ) has an anti-mite treatment.  
     
     
         9 . Slip-proof cover for vehicle tyres according to  claim 1  characterised in that the cord that forms the textile fabric ( 1 ) has an anti-bacterial treatment.  
     
     
         10 . Slip-proof cover according to  claim 1  characterised in that it is constituted as an annular piece with a seam on the outer fold of the ends.  
     
     
         11 . Slip-proof cover according to  claim 1  characterised in that it is constituted as a rectangular piece with closure means at its ends.  
     
     
         12 . Slip-proof cover according to  claim 11  characterised in that the closure means are Velcro strips.
