Definitions

  • This invention relates to a hand held device for propelling a projectile which, when hitting an individual, will render them temporarily incapacitated without permanent injury.
  • the spray can requires that the user be close to the person, a situation to be avoided if at all possible. Obviously, factors such as wind and distance lowers the effectiveness of this method of protection. While the electrical shock device can be effective when the target is somewhat further away, the ultimate physical consequence of the electrical shock cannot always be anticipated thereby making the use of this method somewhat unpredictable. Also heavy clothing may prevent the projectiles from contacting a person's body.
  • the general intent of the subject invention is to provide a personal defense device that overcomes the above outlined shortcomings and can be used by both law enforcement officials and private individuals with equal effectiveness.

  • an agent such as pepper powder, or a gas or liquid
  • Each projectile includes sidewalls closed at one end by an aerodynamically shaped point and closed at the other end by a base member thereby forming a chamber for holding a disabling agent, with the sidewalls having formed therein fracture lines preferably extending both longitudinally and laterally to enhance the breaking of the walls on impact for causing lateral distribution of the agent from the projectile.

Forward movement of the trigger brings the angular tip ofthe release cam 76 into contact with the adjacent cam end 55, serving to rotate the pawl 52 and allowing the cam end to move past the end of the cocking arm 70 thereby permitting the firing pin to be driven into contact with the primer cap 33B.

Abstract

L'invention concerne un ensemble cartouche (21) et poignée (20) propulsant un projectile (28) à parois frangibles (89) lesquelles forment une cavité (93) qui renferme un agent (temporairement) invalidant. Lorsqu'il atteint son objectif, le projectile s'ouvre et laisse échapper l'agent en question sur cet objectif. La cartouche comporte une chambre (27A) pour le projectile, et la poignée comporte un système de mise à feu (46A), à position armée et non armée, ainsi qu'un déclencheur (37A) qui permet de faire passer ce système de la position armée à la position non armée. Il existe d'ailleurs un dispositif pour verrouiller la cartouche à la poignée, y compris la possibilité d'armer le système de mise à feu lorsque la cartouche et la poignée sont ainsi verrouillées. Enfin, l'ensemble comporte un dispositif pour propulser le projectile hors de la cartouche à destination de la cible, suite à la mise à feu par le déclencheur.
