First Claim
1. A firearm adapter, comprising:
- an upper plate member on the adapter having an upper side and a lower side;
a clamp on the upper side of the adapter member, the clamp having clamp edges for allowing the adapter to be clamped to picatinny rails located beneath a firearm, the upper plate member having an indention in the lower side, the indentation having a first end wall and a second end wall, which is opposite to the first end wall;
a swing plate pivotally attached to the first end wall of the indentation, the swing plate having a lower surface with picatinny side edges for supporting an accessory thereon; and
a sliding switch on the adapter for allowing the swing plate to be released from a horizontal locked position to be able to rotate to a substantially vertical position.

Abstract
Adapter devices, apparatus, systems and methods of allowing a firearm to be supported by a foldable fore grip/gun handle. The fore grip gun handle can have bipod type legs that can be extendable from the handle. The fore grip handle can be just a vertical extension. The adapter can allow for the fore grip/gun handle to move from a fold back position along the bottom of the firearm so that the firearm can be easily carried, and the adapter to can allow for the handle to move down to a vertical support position beneath the firearm when the firearm is to be used. The adapter can also support a light in both a folded position and in a downwardly extended position, where light can be aimed forward, rearward to the side and/or pointed down from the firearm. The adapter can allow for a dual functioning component that can be either or both a fore grip and/or a light source. Other versions of the adapter can include a slidable thumb switch for locking a swinging plate with picatinny side rails to a main plate, and spring loaded detents for locking the swinging plate in substantially vertical orientations. Additionally, a folding rail system can be substituted for the existing picatinny rail system on firearms. The folding rail can have mounting holes for allowing the entire folding rail to be directly attached to the firearm, and have a hinge for allowing portions of the picatinny rails to pivot relative to the rest of the picatinny rails.

8. A method of attaching a foldable accessory mounting plate to a firearm, comprising the steps of:
-
providing a firearm having opposite facing picatinny rails underneath the firearm; providing a top plate member having an upper side with clamp edges and a lower side with an indentation; providing a bottom plate member that is sized to substantially fit within the indentation on the lower side of the top plate member; clamping the clamp edges of the top plate member about the picatinny rails; pivotally attaching one end of the bottom plate member adjacent to a wall within the indentation in the lower side of the top plate member; locking the bottom plate member into a folded horizontal position parallel to the top plate member by a sliding switch being moved in one direction; and releasing the bottom plate member to rotate to a substantially vertical position by moving the sliding switch in an opposite direction. - View Dependent Claims (9, 10, 11)

12. A folding rail adapter for firearms, comprising:
-
a first plate shaped member having an upper side and a lower side, a first end, and a second end opposite to the first end, the upper side having clamp edges for clamping about picatinny rails located underneath a firearm, the first plate shaped member having an indentation in the lower side; a second plate shaped member having an upper side and a lower side, a first end and a second end opposite to the first end, the lower side having a first longitudinal picatinny rail and a parallel second longitudinal picatinny rail located between the first end and the second end of the second plate shaped member; and a hinge for allowing a first end of the second plate shaped member to pivot in and out of the indentation in the lower side of the first plate shaped member; and a raised switch for allowing the second plate shaped member to pivot from a horizontal position with the first plate shaped member to a substantially vertical position. - View Dependent Claims (13, 14)
