(57) Mechanism for a muniton device. The mechanism includes a housing (1) containing an
arming element (3) and a spindle (9) capable of giving the arming element an axial
movement. The spindle (9) is operatively connected to the arming element (3) via a
conveyor means (10) which has a thread profile (12), the conveyor means being pivotally
journalled in the arming element such that it is able to be turned between a first
position (Figures 1 and 2), wherein the thread profile (12) is in engagement with
the spindle (9), to a second position (Figures 4 and 7) wherein the thread profile
(12) of the conveyor means is disengaged from the spindle. Spring means (4, 13), are
arranged, in the armed position of the conveyor means, to return the arming element
to said engagement with the movable member.
