In the field of landmine clearance there is a need for a detonator member that is effective in detonating mines whilst protecting any apparatus to which it is secured. The invention relates to a detonator member (10) comprising two inclined plates (12, 13) secured together along a common edge to define a fulcrum (14). The plates are pivotably suspended from a further, moveable member (22) so that the axis of pivoting lies forward of the fulcrum (14). On downward movement of the further member (22) the fulcrum engages the ground (23) and causes the plates to pivot so that one of them (12) lies flat on the ground (23). This plate (12) detonates any landmines under it. During the detonation the plate (12) flips upwardly to a substantially vertical, blast- deflecting position. The other plate (13) limits the travel of the blast deflecting plate (12), by virtue of contact with the ground (23).

Dans le domaine du déminage de mines terrestres, il est nécessaire de pouvoir disposer d'un élément de détonateur capable de faire exploser des mines tout en préservant l'appareil, quel qu'il soit, auquel il est fixé. L'invention a trait à un élément (10) de détonateur comportant deux plaques (12, 13) inclinées, fixées ensemble suivant un bord commun de façon à définir un point d'appui (14). Les plaques sont suspendues pivotantes à un élément (22) mobile supplémentaire, de sorte que l'axe de pivotement se situe en avant du point d'appui (14). Lorsque l'élément (22) supplémentaire effectue un mouvement vers le bas, le point d'appui entre en contact avec le sol (23) et fait pivoter les plaques de sorte que l'une d'entre elles (12) se pose à plat sur le sol (23). Cette plaque (12) fait exploser toute mine terrestre située au-dessous de celle-ci. Au cours de l'explosion, la plaque (12) bascule vers le haut dans une position anti-souffle sensiblement verticale. L'autre plaque (13) limite le déplacement de la plaque (12) anti-souffle du fait qu'elle est en contact avec le sol (23).
