Trigger assembly

Abstract

A trigger assembly which enables trigger actuation to be effected using a smaller amount of applied force than previously known, which has a simple and inexpensive construction and an assembly which without the need for expensive and time-consuming maintenance continuously can be used in sport events. The assembly includes a ram arranged for sliding to and fro in an associated guidance between a retracted position and an advanced position where the ram acted on by a compression spring is opening a gas valve, and a pivotable sear arranged for in a first position to hold the ram in retracted position by means of a first hook of the sear engaging a second hook of the ram and in another position to release said engagement. The trigger assembly further includes a supporting device for in a first position to support the sear in its first position and in a second position to allow the sear to pivot from the first to the second position, and an arrangement which by activating the trigger drives the supporting device from its first to its second position. The invention can be applied to rifles, air rifles, air hand guns, paint ball guns, toy guns and the like and can be attached to or removed from a gun with great ease and can be used by all persons, not least persons with weak hands or fingers.

1 . A firing assembly for an air gun, comprising: 
 a valve for controlling the flow of air from a compressed air supply to a firing chamber;    a ram moveable from a first position to a second position in engagement with the valve, the ram biased by a first spring to the second position;    a pivotable sear moveable from a first position engaging a portion of the ram and holding the ram in its first position to a second position releasing the ram, the pivotable sear biased to the first position by a second spring;    a pivoting arm having a fixed end and a free end, the pivoting arm pivotable from a first position to a second position, the pivoting arm biased to the first position by the second spring, the pivoting arm including a roller located on its free end adjacent the sear;    a solenoid having a protrusion adjacent the pivoting arm moveable from a first position to a second position, whereby the protrusion pivots the pivoting arm about its fixed end against the spring bias to its second position when the protrusion is in its second position; and a trigger for actuating the solenoid.    
     
     
         2 . The firing assembly according to  claim 1 , wherein the pivoting arm pivots about an angle of between 5° and 15° between the first and second positions.  
     
     
         3 . The firing assembly of  claim 1 , further comprising further at least one battery, a circuit connecting the battery with the solenoid, and a switch for closing the circuit when being activated by the trigger.  
     
     
         4 . The firing assembly of  claim 1 , wherein the trigger travel is less than 1 mm.  
     
     
         5 . The firing assembly of  claim 1 , wherein the force necessary for pulling the trigger is approximately 2-5 multiplied by the force of gravity.
