Patent

CA 2113574

A screw (1) has a shank (2) and a head (3); there are thread sections (7, 10) on the shank with an unthreaded shank section (13) between them. In the unthreaded section (13) there are grooves (14) in order to make said unthreaded section an elastic region. The screw is thus better capable of withstanding transverse forces acting on the head which cause a bending load on the screw.

Une vis (1) comporte une tige (2) et une tête (3), la tige comprenant des sections filetées (7, 10) séparées par une section non-filetée (13). La section non-filetée (13) comporte des rainures (14) qui servent à rendre élastique cette zone non-filetée. La vis peut ainsi mieux absorber les forces transversales appliquées sur la tête de vis et qui provoquent une charge de flexion sur la vis.
