Foldable and adjustable firearm stock assembly
First Claim
1. A pivotable and length adjustable firearm stock assembly comprising:
- a pivot stock having one end provided with a combined pivoting and latching arrangement movable about a horizontal pivot axis and adapted to be pivotally mounted on the rear end of a firearm, and an opposite end provided with a slide member having lock receiving structure;
a butt stock having one end slidably mounted on the slide member, and an opposite end provided with a butt plate pivotally mounted thereto; and
a movable member having lock structure thereon interconnected between the pivot stock and the butt stock for locking the butt stock in various axial adjustment positions relative to the slide member of the pivot stock,whereby the pivot stock and the butt stock together are movable about the horizontal pivot axis between a folded position adapted to lie adjacent the firearm and an unfolded position adapted to lie rearwardly of the firearm, and the butt stock is slidably adjustable relative to the pivot stock between various collapsed and extended positions, andwherein the pivoting and latching arrangement includes a tube structure adapted to be positioned in the rear end of the firearm, a plunger slidably inserted for movement in the tube structure along the horizontal pivot axis, the plunger having an outer depressible end accessible from one side of the pivot stock, and an inner end connected to a latch member positioned externally on an opposite side of the pivot stock and provided with a latch detent eccentrically located relative to a control aperture of the latch member and adapted to be engaged on the rear end of the firearm, and a spring disposed and engaged between the tube structure and the plunger and biased to normally hold the latch detent in a desired locking position to prevent movement of the pivot stock and butt stock from the folded and unfolded positions, the latch member being movable externally away from the opposite side of the pivot stock in response to movement of the plunger against the bias of the spring to enable movement of the pivot stock and butt stock from the folded and unfolded positions.

Abstract
A pivotable and length adjustable firearm stock assembly includes a pivot stock having one end provided with a combined pivoting and latching arrangement movable about a horizontal pivot axis and adapted to be pivotally mounted on a rear end of the firearm. An opposite end is provided with a slide member having a lock receiving structure. A butt stock has one end slidably mounted on the slide member, and an opposite end provided with a butt plate pivotally mounted thereto. A movable member is interconnected between the pivot stock and the butt stock for locking the butt stock in various axial adjustment positions relative to the slide member of the pivot stock. The pivot stock and the butt stock together are movable about the horizontal pivot axis between a folded position and an unfolded position, and the butt stock is slidably adjustable relative to the pivot stock between various collapsed and extended positions.

4. A pivotable and length adjustable firearm stock assembly comprising:
-
a pivot stock having one end provided with a combined pivoting and latching arrangement pivotally mounted about a horizontal pivot axis on a rear portion of a firearm, the pivot stock having an opposite end provided with a slide member having lock receiving structure formed thereon; a butt stock having one end slidably mounted for axial movement on the slide member, and an opposite end provided with a butt plate pivotably mounted thereto; and an elongated lever having lock structure thereon engageable and disengagable with the lock receiving structure on the slide member, the lever being pivotably mounted on the butt stock and having a front portion provided with the lock structure, and an opposite rear portion controllable to selectively effect engagement and disengagement of the lock structure relative to the lock receiving structure so as to enable various axial adjustment positions of the butt stock relative to the pivot stock, wherein a front portion of the lever extends beyond the one end of the butt stock. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11)

12. A firearm stock assembly comprising:
-
a pivot stock having one end provided with a combined pivoting and latching arrangement pivotally mounted about a horizontal pivot axis on a rear portion of a firearm, the pivot stock having an opposite end with a fixed mounting member projecting therefrom; and a butt stock attached to the fixed mounting member, the pivot stock and the butt stock together being movable about the horizontal pivot axis between a folded position lying adjacent the firearm and an unfolded position extending rearwardly of the fireman, wherein the rear portion of the firearm includes latch engaging structure cooperable and continuously engageable with a latch member of the pivoting and latching arrangement as the pivot stock and butt stock move together about the horizontal pivot axis to define a first locking position for preventing movement of the pivot stock and the butt stock from the folded position, and a second locking position for preventing movement of the pivot stock and the butt stock from the unfolded position, wherein the latch engaging structure is defined by a pair of latch engaging recesses interconnected by a grooved track for guiding the latch member between the latch engaging recesses, and wherein the track has a ramped cam surface that slopes between the pair of latch engaging recesses. - View Dependent Claims (13, 14, 15, 16, 17, 18)
