Definitions

  • This invention relates to a tyre stud consisting of an essentially cylindrical shank with a hard metal tip at one end and a locking flange at the other end, which locks the stud to the tyre.
  • the stud of the invention is characterised in that the locking flange is made of a resilient material, such as rubber or resilient plastic.
  • the locking flange is kept substantially in position despite the tilting movements of the stud.
  • the locking flange can receive forces exerted on the hard metal tip of the stud especially when the road surface is molten, the stud tip being incapable of penetrating into the snow mass or the icy surface.
  • the stud consists of a cylindrical shank 1 with a hard metal tip 2 at its end. At the other end of the stud shank, a locking flange 3 is provided, which locks the stud to the tyre.
  • the locking flange 3 is made of a resilient material, such as rubber or resi- lient plastic.
  • the locking flange 3 is a disc which bends as indicated with the broken line when the stud tilts approx. 10°, for instance.
  • the locking flange 3 locks the stud to the tyre. Owing to its resilience, the edges of the locking flange 3 do not damage the tyre rubber or the tyre fabric.
  • Figure 2 illustrates an embodiment in which the locking flange is equipped with a pad 4.
  • the locking flange and the pad have been combined to form a pad-like locking flange 3.
  • the locking flange 3 has a cylindrical mantle 5, which surrounds the shank 1 of the stud. In this way, the locking flange is well fixed to the stud shank despite the tilting forces.
  • the locking flange and the pad shown in figure 4 make up a combination which is an open cup 3 with a bellows-like shape.
