Fecha de publicación: 17/05/2007 Fuente: WIPO "royal booby" An optical mine clearance probe comprising a handle that is extended through a rod having a geometrical axis and adapted to be driven into a soil to search through it and including a first tubular part, a second part consisting of a movable rod end part including slots adapted to constitute at least two sectors and a mechanism capable of displacing the movable rod end between two extreme positions. One of the positions being one where a part of the rod end constitutes an extremity of the probe, the at least two sectors being adjacent one another in pairs and defining a conical member ending with a tip, and the other position being one in which extremities of the at least two sectors are spread apart from one another, the rod end then being of tubular shape. The mechanism is capable of displacing at least a part of at least one of the sectors in a direction that is different from that of the geometrical axis of the rod while maintaining the part of rod end at the end of the rod so that it always constitutes the extremity of the probe.
