Abstract

L'invention concerne un dispositif à mouvement de va-et-vient. Un élément de va-et-vient qui peut se déplacer en va-et-vient par rapport à un boîtier est sollicité à l'aide d'un élément de sollicitation vers le côté de position avancée à partir du côté de position rétractée ; le boîtier ou l'élément de va-et-vient est pourvu d'une section en prise, respectivement l'autre étant pourvu d'une section de mise en prise ; la section en prise est disposée dans une forme en spirale autour de l'axe de l'élément de va-et-vient ; la section de mise en prise coulisse avec la section en prise en raison de la restriction du mouvement relatif dans la direction axiale de l'élément de va-et-vient en étant mise en prise avec la section en prise ; l'élément de va-et-vient est disposé de façon à se déplacer par rapport au boîtier dans la direction axiale de l'élément de va-et-vient tout en tournant par rapport au boîtier en raison de la section en prise coulissant avec la section de mise en prise ; l'élément de sollicitation sollicite l'élément de va-et-vient dans une direction de rotation lorsque l'élément de va-et-vient avance ; et la section en prise comprend une section de blocage pour bloquer la rétraction de l'élément de va-et-vient en venant en butée contre la section de mise en prise lorsque l'élément de va-et-vient est pressé dans la direction de rétraction sans que la section de mise en prise ne coulisse avec la section mise en prise. À l'aide dudit dispositif à mouvement de va-et-vient, il est possible d'empêcher l'élément de va-et-vient dans la position avancée de se déplacer dans la direction de rétraction même si celui-ci subit une force externe unidirectionnelle pour se déplacer dans la direction de rétraction en raison d'une opération malveillante ou similaire.
