Abstract

A safety mechanism for a projectile weapon includes a stop means such as a lever pivotally mounted to prevent the movement of the trigger to a position enabling the weapon to be discharged. A biasing means such as a spring is also attached to the lever to maintain the lever in the blocking position. Spaced from the trigger on the stock of the weapon is an actuator mounted for movement on the exterior of stock and pivotally connected to a second lever which is pivotally attached to the stock. The first and second levers are connected by a transfer bar such that movement of the actuator shifts the first lever with respect to the trigger to allow the trigger to be moved to the discharge position. The actuator is shown in the form of a slidable plate and a push button.

Claims

1. A safety mechanism for a projectile weapon, the weapon including a stock and a trigger mounted on the stock and capable of being moved between a non-discharge position and a discharge position, comprising:

stop means including a lever arm pivotally movable between a first position blocking movement of a trigger of a projectile weapon from a non-discharge position to a discharge position and a second position permitting movement of the trigger between the non-discharge position and the discharge position, one end of said lever arm engaging the trigger in said first position and being spaced from the trigger in said second position;

means for biasing said lever arm to said first position;

a transfer bar having one end attached to an opposite end of said lever arm and an opposite end;

a lever adapted to be pivotally attached to the weapon and having one end attached to said opposite end of said transfer bar and an opposite end; and

an actuator adapted to be mounted for movement on a stock of the weapon and attached to said opposite end of said lever, and spaced from the trigger a distance

requiring two hands to discharge the weapon whereby when a person moves the weapon into position for firing, at least a portion of one hand engages the trigger and at least a portion of another hand engages said actuator and tenses as the stock is pulled into the person'"'"'s shoulder to move said actuator thereby causing said lever and said transfer bar to move said stop means from said first position to said second position and allow the portion of said one hand to move the trigger to the discharge position.

2. The safety mechanism according to claim 1 wherein said actuator moves approximately three sixteenths of an inch to move said stop means between said first and second positions.

3. The safety mechanism according to claim 1 wherein said means for biasing includes a tension spring having one end attached to an opposite end of said lever arm and having an opposite end attached to the weapon.

4. The safety mechanism according to claim 1 wherein said actuator is a plate slidably mounted on the stock and attached to said opposite end of said lever.

5. The safety mechanism according to claim 1 wherein said actuator is a button mounted on the stock and attached to said opposite end of said lever.
