Fuze for Stun Grenade
A stun grenade includes a fuze assembly secured to a housing adjacent gas outlet ports. The fuze assembly includes a fuze body having contact surfaces located in the flow path of the gas from the outlet ports so that gas flowing from the outlet ports impinges on the contact surfaces. The contact surfaces of the fuze body extend at an angle of no more than about 50 degrees to the first direction.
1 . A stun grenade comprising:
a housing having a chamber centered on an axis and containing an activatable gas generating material;
the housing having outlet ports for directing gas out of the chamber, upon activation of the gas generating material, along a gas flow path that extends in a first direction generally parallel to the axis;
a fuze assembly for activating the gas generating material, secured to the housing adjacent the outlet ports;
the fuze assembly including a fuze body having contact surfaces located in the flow path of the gas from the outlet ports so that gas flowing from the outlet ports impinges on the contact surfaces;
the contact surfaces of the fuze body extending at an angle of no more than about 50 degrees to the first direction.
2 . A stun grenade as set forth in claim 1 wherein the contact surfaces extend at an angle to the first direction that is in the range of from about 20 degrees to about 40 degrees.
3 . A stun grenade as set forth in claim 2 wherein the contact surfaces extend at an angle to the first direction that is about 31 degrees.
4 . A stun grenade as set forth in claim 1 wherein the fuze body comprises two planar wings each having an outer edge surface presented at least partially toward the outlet port, the outer edge surfaces of the wings constituting the contact surfaces of the fuze body, the outer edge surfaces of the wings extending at an angle of no more than about 50 degrees to the first direction.
5 . A stun grenade as set forth in claim 4 wherein the outer edge surfaces of the wings extend at an angle of about 30 degrees to the first direction.
6 . A stun grenade as set forth in claim 1 wherein the fuze body includes a main body portion located radially inward of the outlet ports, the main body portion of the fuze body supporting the contact surfaces of the fuze body at a location radially outward of the main body portion and in the flow path of gas from the outlet port.
7 . A stun grenade as set forth in claim 1 wherein the fuze body includes a threaded mounting post screwed into the housing to secure the fuze assembly to the housing, the mounting post including a fine thread convolution with filleted roots.
8 . A stun grenade as set forth in claim 1 wherein the fuze body includes a threaded mounting post screwed into the housing to secure the fuze assembly to the housing, the mounting post including a thick walled cross section.
9 . A stun grenade comprising:
a housing having a chamber centered on an axis and containing an activatable gas generating material;
the housing having outlet ports for directing gas out of the chamber, upon activation of the gas generating material, along a gas flow path that extends in a first direction generally parallel to the axis;
a fuze assembly for activating the gas generating material, secured to the housing adjacent the outlet ports;
the fuze assembly including a fuze body having a mounting post threaded into the housing to secure the fuze to the housing;
the fuze body having a lever support portion located axially and radially outward of the post and projecting over the outlet port;
the lever support portion being free of gas contact surfaces that extend at an angle of more than about 50 degrees to the first direction;
the mounting post having a fine pitch thread convolution that is threadedly engaged with a fine pitch thread convolution on the housing to secure the fuze to the housing, the fine pitch thread convolution on the fuze body threaded post having a filleted root diameter.
