Abstract

A stun grenade (10) for generating an explosion accompanied by light and/or blaring sound is disclosed. The stun grenade comprises a housing (12) having a body (14), a base (24) and a cover (34) defining an interior cavity (18) housing a cartridge (22) containing an explosive charge (20). A plurality of vents (30, 40) are defined in the housing (12), and a defining wall (32, 42) of each vent is angularly offset from the longitudinal axis of the cavity (18) for discharging explosive energy radially outwardly from the grenade. The stun grenade also includes a bore (25) for facilitating the releasable securement of a variety of attachments, such as a clamp (200) and a tear gas container (206).

Claims

1. A stun grenade comprising:

a fuse;

a cartridge containing an explosive charge in communication with said fuse;

a housing defining a longitudinal axis and an internal cavity for said cartridge;

an end member attached to one end of said housing and having an end wall and a side wall; and

a plurality of vents defined in said end member, at least some of said vents having a first defining wall angularly offset from said longitudinal axis, said at least some of said vents having one end in fluid communication with said cavity and another end in fluid communication with said end wall and said side wall for discharging explosive energy from said housing when said explosive charge is detonated.

2. The stun grenade of claim 1, wherein said end member comprises a bottom member affixed to one end of said housing.

3. The stun grenade of claim 1, wherein said end member comprises a top member affixed to one end of said housing.

4. The stun grenade of claim 2, further comprising a top member affixed to another end of said housing, said top member having an end wall, a side wall and a lower end secured to said cartridge and defining an opening therein communicating with said explosive charge and an upper end for receiving said fuse, said top member defining a plurality of vents, at least some of said vents having a first defining wall angularly offset from said longitudinal axis, said at least some of said vents having one end in fluid communication with said cavity and another end in fluid communication with said top member end wall and said top member side wall.

5. The stun grenade of claim 1 wherein said end member is attached to said housing by crimping.

6. The stun grenade of claim 4 wherein at least one of said members is attached to said housing by crimping.

7. The stun grenade of claim 1, further comprising a container and a means for releasably securing said container to said end member, said container housing a diffusible substance and having a frangible wall confronting at least some of said vents, said frangible wall being breached by a force generated when said explosive charge is detonated for dispersing said substance.

8. The stun grenade of claim 7, wherein said substance is tear gas powder.
