This invention relates to trigger return and safety mechanisms for firearms.
The disposition of the various mechanisms within the frame of a firearm presents challenges, especially when long guns such as carbines are designed for use with sub-caliber (pistol) ammunition. Many factors must be taken into account to ensure a successful firearm, especially when ergonomics are considered important. There is clearly an opportunity to improve firearm design as it relates to mechanisms for trigger return and safety which improve the internal layout of the mechanisms which compete for space in the firearm frame.
In combination, a trigger return and safety mechanism are mountable on a frame of a firearm. Said combination comprises a trigger mountable on said frame and pivotable about a trigger pivot axis. A strut is pivotably attached to said trigger at a strut pivot axis oriented parallel to and offset from said trigger pivot axis. The strut comprises a spring bearing surface and a safety bearing surface. A spring acts between said spring bearing surface and said frame for biasing said trigger into a reset position after said trigger has been pulled. A body is mountable on said frame, said body being movable between a first position wherein said body is not engageable with said safety bearing surface, thereby allowing pivoting motion of said trigger, and a second position wherein said body is engageable with said safety bearing surface thereby limiting pivoting motion of said trigger.
In some embodiments, said spring, said safety bearing surface and said body are positionable within said frame between said trigger and a muzzle end of said firearm.
A trigger return mechanism is mountable on a frame of a firearm. Said trigger return mechanism comprises a trigger mountable on said frame and pivotable about a trigger pivot axis. A strut positionable is on said frame and pivotably attached to said trigger at a strut pivot axis oriented parallel to and offset from said trigger pivot axis. The strut comprises a spring bearing surface. A spring acts between said spring bearing surface and said frame for biasing said trigger into a reset position after said trigger has been pulled.
In some exemplary embodiments, the strut comprises a safety bearing surface. A body is mountable on said frame, said body being movable between a first position wherein said body is not engageable with said safety bearing surface, thereby allowing pivoting motion of said trigger, and a second position wherein said body is engageable with said safety bearing surface thereby limiting pivoting motion of said trigger.
A trigger safety mechanism is mountable on a frame of a firearm. Said trigger safety mechanism comprises a trigger mountable on said frame and pivotable about a trigger pivot axis.
