US12480740 - Two-part folding trigger for a folding firearm

The present disclosure describes a foldable firearm that collapses into a folded state under spring pressure. The foldable firearm may include a foldable grip assembly. The foldable grip assembly may include a foldable pistol grip, a foldable trigger assembly, a folding bar, and a foldable hand stop. The foldable grip assembly may fold into the housing of the foldable firearm. The foldable grip assembly may include a two-part folding trigger a part of which folds forward when the platform folds, to compress the vertical profile of the platform and also to present an inherent safety in the stowed configuration. The foldable firearm can also include a manual safety accessible from outside a housing of the platform that renders a trigger bar incapable of movement and release of the striking mechanism when the safety is engaged.

Claim 1

1 . A folding firearm comprising: a frame comprising a trigger and a fixed rear part extending downward from an axis parallel to a slide direction of a slide of the folding firearm; a foldable grip that rotatably separates from the fixed rear part along a breakaway interface when the folding firearm is folded, and is configured to fold around a first pivot axis that is forward of a front surface of the foldable grip when in a deployed state, the foldable grip further having a grip trigger contact region proximal a top of the front surface; a foldable trigger guard comprising a front leg, a bottom leg, and a folded and a deployed state, the front leg and the bottom leg being oblique to each other in the deployed state, the bottom leg rotatably coupling to the foldable grip via a second pivot axis, the front leg and the bottom leg rotatably coupling via a third pivot axis; and the trigger configured to fold forward and split into a rear part and a forward part when the foldable grip biases the trigger forward, the trigger rotating about a fourth pivot axis. a frame comprising a trigger and a fixed rear part extending downward from an axis parallel to a slide direction of a slide of the folding firearm; a foldable grip that rotatably separates from the fixed rear part along a breakaway interface when the folding firearm is folded, and is configured to fold around a first pivot axis that is forward of a front surface of the foldable grip when in a deployed state, the foldable grip further having a grip trigger contact region proximal a top of the front surface; a foldable trigger guard comprising a front leg, a bottom leg, and a folded and a deployed state, the front leg and the bottom leg being oblique to each other in the deployed state, the bottom leg rotatably coupling to the foldable grip via a second pivot axis, the front leg and the bottom leg rotatably coupling via a third pivot axis; and the trigger configured to fold forward and split into a rear part and a forward part when the foldable grip biases the trigger forward, the trigger rotating about a fourth pivot axis.
