Training grenade
View Patent ↗A training grenade having reversed threading connecting the fuze assembly and the housing. A tubular interior of the fuze assembly contains a two part fuze charge being five times the size of the fuze charge in a live grenade. The two part fuze charge consists of a delay charge and an output charge, where the delay charge burns down first and ignites the output charge, whose explosion simulates the explosion of a live grenade.
1. A training device for simulating a grenade, comprising
a housing having substantially the same weight and dimensions as the housing of the grenade being simulated, said housing comprising:
a threaded opening in a top portion of said housing, wherein the threading of the threaded opening is the reverse of the threading of the threaded opening in the grenade being simulated; and
a plurality of vents surrounding a periphery of the threaded opening; and
a fuze assembly having substantially the same dimensions as the fuze assembly of the grenade being simulated, said fuze assembly comprising:
a threaded portion which screws into the threaded opening of the housing, wherein the threading of the threaded portion is the reverse of the threading of the threaded portion of the fuze assembly of the grenade being simulated; and
a tubular interior containing a two part fuze charge, said two part fuze charge comprising a delay charge, which is ignited by a striker and is located at an upper portion of said tubular interior, and an output charge, which is located in a lower portion of said tubular interior and is ignited by said delay charge;
wherein the two part fuze charge is a multiple in size of the fuze charge in the grenade being simulated; and
wherein, when the output charge detonates, the shock waves and explosive gasses resulting therefrom discharges out through the plural vents of the housing.
2. The training device of claim 1 , wherein the grenade being simulated is a less-lethal grenade.
3. The training device of claim 1 , wherein the housing is colored differently than the housing of the grenade being simulated.
4. The training device of claim 1 , wherein the fuze assembly and housing remain substantially intact after detonation of the output charge, and can thereby be reused.
5. The training device of claim 1 , wherein the two part fuze charge is about two to about eight times the size of the fuze charge in the grenade being simulated.
6. The training device of claim 1 , wherein the two part fuze charge is about five times the size of the fuze charge in the grenade being simulated.
7. The training device of claim 1 , wherein the housing is comprised of rubber.
8. A training device for simulating a grenade, comprising:
a housing having substantially the same weight and dimensions as the housing of the grenade being simulated, said housing comprising:
a threaded opening in a top portion of said housing, wherein the threading of the threaded opening is the reverse of the threading of the threaded opening in the grenade being simulated; and
a fuze assembly having substantially the same dimensions as the fuze assembly of the grenade being simulated, said fuze assembly comprising:
a threaded portion which screws into the threaded opening of the housing, wherein the threading of the threaded portion is the reverse of the threading of the threaded portion of the fuze assembly of the grenade being simulated.
9. The training device of claim 8 , wherein the grenade being simulated is a less-lethal grenade.
10. The training device of claim 8 , wherein the housing further comprises:
a plurality of vents surrounding a periphery of the threaded opening of the housing, wherein, when a charge inside the housing detonates, the shock waves and explosive gasses resulting therefrom discharges through said plural vents.
11. The training device of claim 10 , wherein the fuze assembly and housing remain substantially intact after detonation of the output charge, and can thereby be reused.
12. The training device of claim 8 , wherein the fuze assembly further comprises:
a tubular interior containing a two part fuze charge, said two part fuze charge comprising a delay charge, which is ignited by a striker and is located at an upper portion of said tubular interior, and an output charge, which is located in a lower portion of said tubular interior and is ignited by said delay charge.
13. The training device of claim 12 , wherein the two part fuze charge is a multiple in size of the fuze charge in the grenade being simulated.
14. The training device of claim 12 , wherein the two part fuze charge is about two to about eight times the size of the fuze charge in the grenade being simulated.
15. The training device of claim 12 , wherein the two part fuze charge is about five times the size of the fuze charge in the grenade being simulated.
16. A training device for simulating a grenade, comprising:
a housing having substantially the same weight and dimensions as the housing of the grenade being simulated, said housing comprising:
a threaded opening in a top portion of said housing, wherein the threading of the threaded opening is the reverse of the threading of the threaded opening in the grenade being simulated; and
a fuze assembly having substantially the same dimensions as the fuze assembly of the grenade being simulated, said fuze assembly comprising:
a tubular interior containing a two part fuze charge, said two part fuze charge comprising a delay charge, which is ignited by a striker and is located at an upper portion of said tubular interior, and an output charge, which is located in a lower portion of said tubular interior and is ignited by said delay charge; and
a threaded portion which screws into the threaded opening of the housing, wherein the threading of the threaded portion is the reverse of the threading of the threaded portion of the fuze assembly of the grenade being simulated;
wherein the two part fuze charge is a multiple in size of the fuze charge in the grenade being simulated.
17. The training device of claim 16 , wherein the grenade being simulated is a less-lethal grenade.
18. The training device of claim 16 , wherein the two part fuze charge is about two to about eight times the size of the fuze charge in the grenade being simulated.
19. The training device of claim 16 , wherein the two part fuze charge is about five times the size of the fuze charge in the grenade being simulated.
20. The training device of claim 16 , wherein the housing further comprises:
a plurality of vents surrounding a periphery of the threaded opening of the housing, wherein, when a charge inside the housing detonates, the shock waves and explosive gasses resulting therefrom discharges through said plural vents.
21. The training device of claim 20 , wherein the fuze assembly and housing remain substantially intact after detonation of the output charge, and can thereby be reused.
