De plus, le risque, pour un embout d'entraînement, de If neatly applied against the article 28, the threads 18 no longer advance the screw through the sheet 30.

In addition, the thread 18 of the threaded portion 26 has resisted the pulling forces exerted on the screw 10 or on
l'article 28.Article 28.
Une caractéristique importante de la vis selon l'invention est sa résistance au desserrage sous l'effet de vibrations L'ouverture 31 formée dans latôle 30 peut prendre une forme hélicoïdale ou bien, si la vis peut réaliser un taraudage par coupe, l'ouverture peut être plane, mais non circulaire La résistance à la rotation est réduite lorsque la vis est totalement enfoncée, du fait de la présence des tronçons non filetés 24 de cette vis Ainsi, la vis est généralement tournée au-delà du point o la prise filetée a lieu Pour le desserrage, une vis doit d'abord être déplacée jusqu'au point o les filets peuvent se prendre dans l'ouverture Etant donné An important feature of the screw according to the invention is its resistance to loosening under the effect of vibrations The opening 31 formed in the plate 30 may take a helical shape or, if the screw can make a tapping by cutting, the opening can be flat, but not circular The resistance to rotation is reduced when the screw is fully depressed, because of the presence of non-threaded sections 24 of the screw Thus, the screw is generally turned beyond the point o the threaded socket takes place For loosening, a screw must first be moved to the point where the threads can be caught in the opening Given
qu'il n'existe qu'une position permettant à la vis d'amor- that there is only one position allowing the screw to
cer le dégagement et qu'il est très peu probable que la vis arrive dans cette position, la résistance au desserrage sous l'effet des vibrations est améliorée par la présente invention. Les figures 2, 3 et 4 montrent qu'une vis unique peut être utilisée avec des articles de diverses épaisseurs prédéterminées Dans de nombreuses situations, des matériaux isolants de différentes épaisseurs sont utilisées sur un lieu unique de travail Une variante de l'invention comprend plusieurs tronçons non filetés 24 et plusieurs tronçons filetés correspondants 26 La figure 2 montre l'organe 10 de fixation assujettissant l'article 28 d'épaisseur relativement grande Les figures 3 et 4 montrent que le même organe de fixation peut être In view of the fact that it is very unlikely that the screw will be in this position, the resistance to loosening under the effect of vibration is improved by the present invention. Figures 2, 3 and 4 show that a single screw can be used with articles of various predetermined thicknesses In many situations, insulating materials of different thicknesses are used in a single workplace A variant of the invention comprises several non-threaded sections 24 and a number of corresponding threaded sections 26 FIG. 2 shows the fastener 10 securing article 28 of relatively large thickness FIGS. 3 and 4 show that the same fastener may be
utilisé pour la fixation d'articles moins épais. used for fixing thinner articles.
La figure 5 montre que, en l'absence de la résistance à la pénétration imposée par l'entrée en contact de la tête 12 avec l'article 28, la pénétration de l'organe de fixation peut continuer sous l'application d'une force axiale légère en même temps qu'une rotation continue de FIG. 5 shows that, in the absence of the resistance to penetration imposed by the coming into contact of the head 12 with the article 28, the penetration of the fixing member can continue under the application of a light axial force along with a continuous rotation of
