Abstract
An ordnance firing mechanism for striking detonators by a strike pin which is translatable relative to a support, the strike pin being driven in translation by actuation apparatus including a lever connected to the strike pin and pivotable relative to the support, a pivotable pawl able to release the lever 4, a propelling device acting on the lever and affixed to the support 1, a driver acting on the pawl and through it implementing rotation of the lever thereby arming the strike pin and releasing the lever, the driver including a control rod for translation relative to the support and having recesses cooperating with the pawl and with a heel cooperating with the lever.
Claims10
An ordnance firing mechanism for striking a detonator, comprising a strike pin (2) mounted for translation relative to a support (1), the strike pin (2) being translatable by actuation means (4, 9, 11, 12, 18) for sequentially:
- moving the strike pin from a rest position to an armed position wherein a strike-pin propelling device is armed;
- moving the strike pin from an armed position into a firing position wherein it is forced by the propelling device against a detonator and
- returning the strike pin to its rest position and retaining it there;
- the actuation means comprising:
- a lever (4) connected to the strike pin (2) and pivotable relative to the support (1);
- a pivotable pawl (9) for releasing the lever (4), a propelling device (11, 18) affixed to support (1) for driving the lever;
- and
- drive means (12) for acting on the pawl (9) and through the pawl for rotating the lever (4), arming the strike pin (2), and then releasing the lever (4);
- said propelling device comprising a movable rod (12) translatable relative to said support (1), said movable rod having recesses (15, 16) therein that cooperate with the pawl (9) and having a heel (17) that cooperates with the lever (4), wherein
- said recesses comprise a first recess (15) having a cylindrical contour for rotating the pawl (9) and a second recess (16) adjacent said first recess, the second recess having a depth corresponding to a strike depth of the strike pin and for receiving the pawl (9) for rotating the lever (4) about its shaft (6).
