Abstract
A trigger assembly for launching the projectile of a spring loaded weapon such as a harpoon, cross-bow or the like is disclosed having a detent adapted to engage the rear end of the projectile. The detent swingable about an axle fixed to the butt stock and a spring member is supported within the butt stock to engage said detent. The forces created by the projectile acting on the detent, cause said spring member to curve into a reactive position, the curvature of the spring in the reactive position is limited and a trigger member is provided for displacing the spring from its curved position into a position releasing the reactive force on said detent.
Claims10
A trigger assembly for launching the projectile of a spring loaded weapon comprising a barrel hollow butt stock in which the rear end of the projectile is received, an axle fixedly mounted in said butt stock transversely to the direction of the barrel, a detent adapted to engage the rear end of the projectile, said detent being mounted within said butt stock and swingable about said axle, said detent having a slot through which said axle passes, said slot extending at an angle to the axis of said barrel so as to be axially movable and pivotable about the axle, a spring means supported within said butt stock, said spring means including a spring, said spring directly engaging said detent, and said spring means being in stressed condition when the gun is in a cocked condition to produce a force on said detent to hold a projectile in a retracted position, means located within said butt stock for limiting the flexing of said spring means when a projectile is in a cocked condition, and a trigger member for displacing said spring means from its flexed position when the gun is in a cocked position to a position releasing the spring means force on said detent.
