AI Technical Summary

Benefits of technology

The invention is a trigger pull that is easy to light, prevents premature firing, and reduces complexity in manufacturing. The trigger has internal parts, including two toggles: one lower and one upper. The trigger is designed to improve the trigger pull for shooters and manufacturers.

Problems solved by technology

At this stage the force of the firing pin spring via the firing pin which itself is pushing on the firing pin retainer causes the toggle linkage to collapse.

Embodiment Construction

[0020]With regards to firearms, the invention is able to facilitate a light trigger pull, prevent premature firing and importantly, significantly reduce excess complexity in manufacturing assembly and repair. Throughout this description the term forward, forwards, front or fore shall refer to the orientation of the firearm and trigger towards the direction of the barrel of the firearm. Throughout this description the term rearward, rearwards, rear or aft shall refer to the orientation of the firearm and trigger towards the direction of the butt of the firearm.

[0021]With reference to FIG. 3 the trigger assembly is held to the firearm either directly, by an adapter, by a hanger or other necessary device via the Locating Pin Fore 61 and the Locating Pin Rear 62. The trigger internal parts are captured within an external chassis being the Left Sheet Chassis 31 and the Right Sheet Chassis 32 which can be made of metal sheet or other suitable material. Undertravel Screw 33 is located in L...

Abstract

A trigger mechanism for a firearm which has a light trigger pull, reliably contains the high forces of the firing pin spring and achieves this with a mechanism which is simple and with few parts. A toggle linkage prevents the firing pin retainer releasing the firing pin whilst still allowing a light pull. It contains no internal sear and no pins within the toggle mechanism. It is adjustable for variations in manufacturing and can cater for various levels of trigger pull force. It realizes considerable economies for production, assembly and repair without sacrificing functionality.

Description

BACKGROUND OF THE INVENTIONField of the Invention[0001]This invention relates to a trigger assembly for firearms including target rifles. The mechanism provides for a light trigger pull whilst greatly simplifying the mechanism.Description of Prior Art[0002]To enhance accuracy a great many shooters, desire the lightest trigger pull possible. However, the trigger must contain the high force of the firing pin spring to prevent inadvertent firing. Usually this force is contained by a sear type of arrangement. A sear may be described as a physical impasse being a block, other analytic or primitive shape or part, aligned with a mate to block movement until such time as it is moved. A trigger that is set too light or with too little sear engagement can have a tendency to go off prematurely. Containing the high force of the firing pin spring is thus at odds with the idea of a light trigger pull.[0003]Referring to FIG. 1, a conventional trigger is in the cocked position. In this position a f...
