  • the shank connector 126 has a coupling 132 adapted for coupling with the connector of the shank 83 of the fastener 80.
  • the coupling 132 comprises a Torx® fitting.
  • the fastener 80 is operated by the tool 120 to attach a first object comprising, for example, a batten to a second object comprising, for example, a wall.
  • a hole is first drilled in and through the batten and in the wall, using a drill bit having two drilling portions, a first drill bit portion substantially matching the diameter of the shank 83 of the fastener 80 and the second drill bit portion substantially matching the diameter of the cover 85 of the fastener 80.
  • the first end 95 of the shank 83 of the fastener 80 is then inserted through the hole in the batten and into an outer end of the hole of the wall.
  • the first coupling 128 of the shank and cover connector 124 at the first end of the body 122 of the tool 120 is coupled with the connector of the shank 83 and the second coupling 130 of the shank and cover connector 124 is coupled with the connector of the cover 85.
  • the shank connector 126 at the second end of the body 122 of the tool 120 is connected to a drill, which is operated to rotate the tool 120 in a clockwise rotational direction. Rotation of the tool 120 causes rotation of the shank and cover connector 124 of the tool 120 and, due to coupling therebetween, rotation of the shank 83 and the cover 85 of the fastener 80 in a clockwise rotational direction.
  • the first portion 89 of the shank 83 is thus threadedly engaged, or screwed, into the wall and the cover 85 is threadedly engaged, or screwed, into the batten.
  • the batten is thus attached to the wall with an inner surface of the batten adjacent an outer surface of the wall. When the fastener 80 is substantially fully inserted into the batten, the cover 85 will grip the batten and hold it in place against the wall.
  • the cover and shank connector 124 of the tool 120 is decoupled from the shank 83 and the cover 85.
  • the tool is rotated through 180 degrees and the shank connector 126 of the tool 120 is coupled with the connector of the shank 83 of the fastener 80.
  • the shank and cover connector 124 of the tool 120 is connected to a drill, which is operated to rotate the tool 120 in an anticlockwise rotational direction. Rotation of the tool 120 causes rotation of the shank connector 126 of the tool 120 and rotation of the shank 83 (but not the cover 85) of the fastener 80 in an anticlockwise rotational direction.
  • the first portion 89 of the shank 83 is thus threadedly disengaged, or screwed out, of the wall, which causes the cover 85 of the fastener 80 to move away from the wall.
  • the cover 85 As the cover 85 is threadedly engaged with the batten, it grips the batten and movement of the cover 85 of the fastener 80 away from the wall, moves the batten away from the wall.
  • This provides a gap between the inner surface of the batten and the outer surface of the wall, whilst maintaining attachment of the batten to the wall. This allows the batten to be attached to the wall and to be in a substantially straight and vertical / horizontal attitude, without the need for packers between the batten and the wall.

Abstract

La présente invention concerne un élément de fixation (80) pour fixer un premier objet à un second objet comprenant une tige (83) ayant une première partie s'étendant à partir d'une première extrémité de l'élément de fixation (80) comportant un filetage dans un premier sens, une deuxième partie adjacente à la première partie, une troisième partie adjacente à la deuxième partie et s'étendant jusqu'à une seconde extrémité de l'élément de fixation (80), un couvercle cylindrique (85) ayant une surface externe comportant un filetage dans le premier sens et une surface interne sensiblement lisse, qui est positionné sur la troisième partie de la tige (83) et est fixé de manière mobile à la tige (83) pour permettre au couvercle (85) de tourner autour de la tige (83) mais pas de se déplacer dans le sens de la longueur le long de la tige (83), la tige (83) et le couvercle (85) pouvant tourner dans un premier sens de rotation pour venir en prise par filetage avec la première partie de la tige (83) dans le second objet et pour venir en prise par filetage avec le couvercle (85) dans le premier objet, afin de fixer le premier objet au second objet avec une surface interne du premier objet adjacente à une surface externe du second objet, et la tige (83) pouvant tourner dans un second sens de rotation opposé pour désaccoupler partiellement par filetage la première partie de la tige (83) du second objet, afin de déplacer les deuxième et troisième parties de la tige (83), le couvercle (85) étant fixé à la tige (83) et le premier objet étant en prise par filetage avec le couvercle (85) à l'opposé du second objet pour fournir un espace entre la surface interne du premier objet et la surface externe du second objet, tout en maintenant la fixation du premier objet au second objet. Un outil est prévu pour le fonctionnement de l'élément de fixation.
