Claim 8

The detonating device of claim 6, wherein said guiding sleeve is substantially cylindrical and axially aligned with said primer; said guide sleeve having diametrically opposed longitudinally extending slots at its end opposite from said primer, separate diametricallY opposed longitudinally extending slots at its end adjacent said primer, and a central web portion provided with an axially extending guide bearing; said firing pin including a shaft extending through said guide bearing at its end opposite said primer and a collar engaging the interior walls of said cylindrical sleeve at its end adjacent said primer; said spring being a coil spring concentric with said firing pin shaft and extending between said sleeve web and said firing pin collar; said clamping claw being substantially U-shaped with a web portion diametrically extending through said slots in said sleeve at the end opposite from said primer, and spring leg portions axially extending along diametrically opposite sides of said sleeve toward said primer terminating in inwardly extending guide fingers guidingly received within said slots at the end adjacent said primer; each of said fingers having said abutment and said cam follower surface; each of said slots at the end adjacent said primer having said cam edge axially aligned with respective ones of said cam follower surfaces.

Claim 9

The detonating device of claim 7, including a substantially cup-shaped primer enclosing casing holding said primer against said housing and provided with an outwardly extending annular flange; said guide sleeve engaging said casing outwardly extending annular flange and clamping it tightly against said housing; a disk threaded in said housing and clamping the end of said guide sleeve opposite from said primer.

Claim 10

The detonating device of claim 1, wherein said housing has an axially extending externally threaded hollow extension provided with an ignition channel in its interior and being adapted for threading engagement into a main powder charge housing; said housing having a homogenously integral diaphragm sealing the interior of said housing and closing the interior of said ignition channel immediately between said primer and said threaded extension.

Claim 11

The detonating device of claim 1, adapted to be used for mines, wherein said external force responsive means for rotating providing tipping movement includes a rod-shaped triggering element extending away from said housing in a manner adapted to be engaged by an external force producing mass, and a wobbler plate drivingly connected to said triggering member and mounted on said housing for tiling movement; a guide sleeve guiding said firing pin movement axially between said positions; said entrainment means for moving said firing pin including a clamping claw engaging said firing pin in said first position to prevent movement of said firing pin toward said primer, and flexible means drivingly connecting said clamping claw to said wobbler plate.

Claim 12

The detonating device of claim 2, wherein said housing has an outwardly extending flange; said wobbler plate having integral weakened portions around its circumference; a clamp member mounted on said flange to clamp said weakened portions therebetween; said weakened portions, said flange and said clamp member constituting means for preventing tipping of said wobbler plate at forces thereon below a predetermined force and for effecting breaking of said weakened portions to permit tipping motion of said wobbler plate above predetermined force.

Claim 13

The detonating device of claim 3, wherein said clamp member is a nut provided with threads on its interior threadably engaging said flange and with threads on its exterior; said wobbler plate having a main body portion interior of said weakened portions; a safety clamping nut threaded on said exterior threads of said clamp member and clamping said wobbler plate main body portion securely against said flange to prevent unintentional detonation, and said safety clamping nut being adapted for removal prior to using the detonating device.

Claim 14

The detonating device of claim 3, wherein said weakened portions constitute an integral annular thin rim annularly clamped against said flange by said clamp member sealing the interior of said housing.
