Abstract

A hand grenade includes a main body ( 10 ), a receiver ( 3 ) holding a cartridge chamber ( 2 ), a firing pin ( 6 ) that acts in the manner of a pendulum and a ball ( 7 ) located between facing conical surfaces on the firing pin ( 6 ) and on a wall ( 8 ) of the main body.

What is claimed is: 
     
         1 . A hand grenade comprising:
 a main body,   a receiver holding a cartridge chamber,   a firing pin that acts in the manner of a pendulum, and   a ball located between facing conical surfaces on the firing pin and on a wall of the main body.   
     
     
         2 . The hand grenade as claimed in  claim 1 , in which the diameter of the lower portion of the firing pin is substantially greater than the diameters of the upper and central parts of the firing pin. 
     
     
         3 . The hand grenade as claimed in  claim 1 , in which one end of the firing pin is positioned in a hole in the receiver with a spring acting between the receiver and the firing pin. 
     
     
         4 . The hand grenade as claimed in  claim 1 , in which a safety ring-pin is inserted in a hole in the receiver to prevent inadvertent movement of the receiver relative to the main body. 
     
     
         5 . The hand grenade as claimed in  claim 4 , in which the receiver is free to move vertically and to rotate when the safety ring-pin is removed.
