Stun grenade with time delay trigger

Abstract

A grenade simulator comprises a housing with an integral internal track. A carriage is mounted on the track for linear movement. A travel limit is provided at one end of the track to limit movement of the carriage on the track. A gas source is installed on the carriage. A drive spring installed between the carriage and the housing for urging the carriage against the travel limit. A multi-link trigger is installed on the housing for holding the carriage away from the travel limit until the multi-link trigger is released. A bayonet opens the gas source upon the carriage reaching the travel limit. A release delay is integral with the multi-link trigger.

1 . A grenade simulator comprising:
 a housing;   a track integral to the housing;   a carriage mounted on the track;   a travel limit to movement of the carriage on the track;   an gas source installed on the carriage;   a drive spring installed between the carriage and the housing for urging the carriage against the travel limit;   a multi-link trigger installed on the housing for holding the carriage away from the travel limit until the multi-link trigger is released; and   means for initiating operation of the gas source upon the carriage reaching the travel limit.   
     
     
         2 . The grenade simulator of  claim 1 , further comprising:
 a release delay.   
     
     
         3 . The grenade simulator of  claim 2 , the multi-link trigger further comprising:
 a spring loaded handle mounted to pivot on an axis of rotation from a closed position to an open position and extending from the housing to be grasped;   a cam terminating one end of the handle;   a lever mounted for rotation on a fulcrum mounted to the housing;   a cam follower formed in a first arm of the lever, the cam follower being in contact with the cam; and   a latch terminating a second arm of the lever.   
     
     
         4 . The grenade simulator of  claim 3 , further comprising:
 the spring loaded lever being positionable with the handle in its closed position to allow location of the latch to restrain the drive spring with the carriage displaced from the travel limit.   
     
     
         5 . The grenade simulator of  claim 4 , the release delay comprising:
 an escapement including an escape wheel section mounted to the handle and an anchor mounted to engage the escape wheel.   
     
     
         6 . The grenade simulator of  claim 5 , further comprising:
 an air bag stored within the housing for inflation from the gas source.   
     
     
         7 . The grenade simulator of  claim 5 , further comprising:
 a flash source housed at one end of the housing in a light transmitting semi-globe.   
     
     
         8 . The grenade simulator of  claim 7 , the flash source further comprising:
 combustion configured aluminum in an oxygen enriched medium.   
     
     
         9 . A time controlled release mechanism comprising:
 a track;   a carriage mounted on the track;   a travel limit to movement of the carriage on the track;   a drive spring mounted with respect to the carriage and track for urging the carriage against the travel limit;   a lever mounted for rotation on a fulcrum attached to the track, a first arm of the lever having a latch for engaging the drive spring and a second arm of the lever including a cam follower;   a spring loaded handle mounted for rotation with a cam disposed on one end of the handle riding against the cam follower;   an escape wheel arc disposed on the spring loaded handle; and   an anchor mounted for oscillatory rotation and engaging the escape wheel arc.   
     
     
         10 . The time controlled release mechanism of  claim 9 , further comprising:
 a grenade initiator actuated by movement of the carriage to the travel limit.   
     
     
         11 . The time controlled release mechanism of  claim 10 , further comprising:
 the cam of the spring loaded handle urging rotation of the lever to move the latch from a position restraining the drive spring to a position releasing the drive spring.   
     
     
         12 . The time controlled release mechanism of  claim 10 , further comprising:
 a gas source mounted on the carriage.   
     
     
         13 . A stun grenade comprising:
 a spring biased initiator mechanism;   a lever mounted for rotation on a fulcrum, a first arm of the lever providing a latch for restraining the spring biased initiator mechanism and a second arm of the lever including a cam follower;   a spring loaded handle mounted for rotation with a cam disposed on one end of the handle riding against the cam follower;   an escape wheel arc disposed on the spring loaded handle; and   an anchor mounted for oscillatory rotation engaging the escape wheel arc.   
     
     
         14 . The stun grenade of  claim 13 , further comprising:
 a gas source which the spring biased initiator mechanism initiates flow from upon release from the catch.   
     
     
         15 . The stun grenade of  claim 14 , further comprising:
 a flash source installed to emit light.   
     
     
         16 . The stun grenade of  claim 15 , further comprising:
 a rupturable airbag connected to the gas source for inflation upon initiation of flow.
