Definitions

  • the device consists of a number of blade-edged points set in a radial position around and underneath the head of bolts nuts and washers. These blade-edged points can be of any size from the full surface of the bolt available to smaller points set in a row.
  • blade-edged points engage with the surface of the material being joined during the final phase of the tightening operation.
  • the blade-edged points Upon contact with the surface of the material, the blade-edged points penetrate the material surface, thus preventing further rotation of the bolt.
  • the nut will then, upon further tightening, draw the blade-edged points under the head of the bolt into the material surface, ensuring that the bolt will not rotate any further.
  • the blade-edged points would penetrate sufficiently to render the fixing secure against movement, vibration or torsion effect, thus ensuring a join that would remain tight under all conditions.
  • This device could of course be affixed to nuts and washers, and would further enhance their fixing properties. Various combinations of additional nuts and washers would provide the ability to cover most fixing requirements.

Abstract

Comparées à des vis de montage ou autres types de vis (ou à des ensembles rondelles/goujons/écrous d'usage actuel), les pointes à tranchant de l'invention qui sont appliquées sur les surfaces correspondantes d'écrous/vis ou de rondelles utilisés en cours de fabrication présentent une résistance à la rotation bien supérieure APRES la phase de serrage. Une fois la phase de serrage terminée, ces vis sont pratiquement indéserrables quelles que soient les conditions. Il en résulte un produit beaucoup plus sur tant pour le consommateur que pour le fabricant. Les points à tranchant peuvent tourner en continu dans le sens radial depuis le centre vers la périphérie de la vis, ou bien présentent des décrochements ou des interruptions sur leur longueur (en travers des surfaces correspondantes).
