Abstract (en)

The lock comprises a box-shaped body (10) inside which a bolt (12) slidable along a first direction and a set of adjacent tumblers (14a, 14b) movable along a second direction orthogonal to the first direction are housed. Each tumbler (14a, 14b) has a toothed opening (30), a recess (26) and an upper slot (22) and a lower slot (24). A pin (44) protruding transversally from the bolt (12) passes through all the openings (30); a first guiding pin (40) fixed to the box-shaped body (10) passes through all the upper slots (22) and a second guiding pin (42) fixed to the box-shaped body (10) passes through all the lower slots (24). The lock also comprises: an auxiliary element (36) having an eyelet-shaped through-hole (38) and arranged within the upper slot (22) of at least one tumbler (14b), the first guiding pin (40) passing through the eyelet-shaped hole (38); and a device which is associated with the box-shaped body (10) and is suitable for stopping any movement along the second direction of the tumbler (14b), inside the upper slot (22) of which the auxiliary element (36) is inserted.
