REMOVABLE AND ADJUSTABLE STOCK STABILIZING HOOK ATTACHMENT FOR RIFLE BUTTSTOCKS
A stock stabilizer hook attachment, in the shape of a generally triangular or L-shaped body, can be removably secured to the lower rear edge of a standard rifle stock butt. Most rifles are equipped with front and rear swivel or fixed sling studs which can be used to attach a sling. In order to attach the hook attachment of the present invention to a conventional rifle but having installed swivel studs, the rear swivel or fixed sling stud is removed, the hook attachment is positioned on the rifle butt, and a screw/bolt is used to secure the hook attachment to the stock butt. For one embodiment of the invention the hook attachment is slidably adjustable along the lower edge of the stock butt, and can be tightened in any position within a provided range of movement. Another embodiment of the invention is non-adjustable.
This application has a priority date based on the filing of provisional patent application 60/784,003, which was filed on Mar. 19, 2006.
FIELD OF THE INVENTIONThis invention relates, generally, to firearms and more particularly to attachments for a rifle buttstock that enhance the weapon's accuracy and stability when fired in a prone position for hunting, competition, target shooting and sniping.
BACKGROUND OF THE INVENTION Hunting, competition, sniper and target-shooting rifles are frequently equipped with a built-in stock stabilizer hook, frequently called a butt-hook, that a prone shooter can employ to stabilize the gun by grasping it with one or more fingers of the non-trigger hand. The trigger hand is then used to actuate both the cartridge reloading/eject mechanism and the trigger. A butt-hook rifle stock 100 having an adjustable cheek rest 101 is shown in
The present invention provides a stock stabilizer hook attachment that can be removably secured to the lower rear edge of a standard riffle stock butt. Most rifles are equipped with front and rear swivel or fixed sling studs which can be used to attach a sling. In order to attach the hook attachment of the present invention to a conventional rifle but having installed swivel studs, the rear swivel or fixed sling stud is removed, the hook attachment is positioned on the rifle butt, and a screw/bolt is used to secure the hook attachment to the stock butt. For one embodiment of the invention the hook attachment is slidably adjustable along the lower edge of the stock butt, and can be tightened in any position within a provided range of movement. Another embodiment of the invention is non-adjustable. A third embodiment is also non-adjustable, but is secured to swivel stud in the rifle stock via an attachment block, a pin and a second swivel stud that allows the use of a sling once the hook attachment is installed.

Referring now to FIGS. 30 to 35, the adjustable fourth embodiment hook attachment body 2901 is similar to the first embodiment body 301, in that it has a longitudinal slot which provides forward and aft adjustability of the hook attachment body 2901. It differs from the first embodiment hook attachment body 301 in that it has an L-shaped, rather than triangular, side profile. Exposure of the head 2901 of the rear swivel or fixed sling stud 201R is attributable to this L-shaped profile. Given that the position of the rear swivel or fixed sling stud varies considerably from rifle to rifle, a rear end portion of any of the hook attachment bodies 301, 1001, 1701, and 2901 can be extended so that it can be trimmed to fit the rifle stock on which it is installed.
Any of the bodies 301, 1001, 1701 and 2901 of the four embodiments of the stock stabilizer hook attachment disclosed herein can be fabricated by injection molding or casting using thermoplastic and thermosetting plastic resins. Alternatively, the various embodiments of the stock stabilizer hook attachment can be carved from wood, machined or cast from a structural metal such as aluminum, magnesium, brass or steel, or fabricated from hard, semi-resilient materials, such as hard rubber or other similar polymeric materials.
Although only several embodiments of the new removable and/or adjustable stock stabilizing hook attachment for rifle buttstocks have been heretofore described, it will be obvious to those having ordinary skill in the art that changes and modifications may be made thereto without departing from the scope and the spirit of the invention as hereinafter claimed.
Claims
1. A removable stock stabilizer hook attachment mountable to a lower rear portion of a rifle stock, said stock stabilizer hook attachment comprising:
- a stabilizer hook body having a forward face around which at least one finger of a shooter can be wrapped and an upper semi-cylindrical channel which mates with a rearward portion of a rounded lower edge of the rifle stock; and
- means for attaching said block to the lower rear portion of the rifle stock.
2. The removable stock stabilizer hook attachment of claim 1, wherein said body has a generally triangular side profile.
3. The removable stock stabilizer hook attachment of claim 1, wherein said body has a generally L-shaped profile.
4. The removable stock stabilizer hook attachment of claim 1, wherein said means for attaching comprises:
- an aperture in said body positioned in the middle of said semi-cylindrical channel; and
- a threaded fastener insertable through said aperture and which engages a threaded hole generally centered on the rearward bottom edge of the rifle stock.
5. The removable stock stabilizer hook attachment of claim 4, wherein said aperture is a slot providing fore and aft adjustability of the stock stabilizer hook attachment.
6. The removable stock stabilizer hook attachment of claim 4, wherein said aperture is a cylindrical aperture sized to receive the threaded fastener, thereby providing no adjustability for forward and aft movement of the body.
7. The removable stock stabilizer hook attachment of claim 1, wherein said body is fabricated from materials selected from the group consisting of wood, polymeric plastic resin, hard rubber, and metal.
8. The removable stock stabilizer hook attachment of claim 7, wherein said polymeric plastic resin is selected from the group consisting of thermoplastic resins and thermosetting plastic resins.
9. The removable stock stabilizer hook attachment of claim 4, wherein said threaded fastener is selected from the group consisting of wood screws, machine screws, threaded fixed sling studs, and threaded swivel sling studs.
10. The removable stock stabilizer hook attachment of claim 1, wherein said means for attaching comprises:
- an aperture in said body positioned in the middle of said semi-cylindrical channel;
- a threaded sling stud having a head with a sling attachment aperture transverse to the central axis of the stud;
- an attachment block having a cylindrical recess which fits over the head of the threaded sling stud, said attachment block having an aperture which aligns with the sling attachment aperture and a threaded aperture coaxial to the cylindrical recess;
- a pin for inserting through the apertures of the attachment block and the head of the sling stud; and
- an auxiliary swivel stud that secures the hook attachment body to the attachment block.
11. The removable stock stabilizer hook attachment of claim 10, wherein said hook attachment body had a recess which fits over the attachment block and is sized to prevent the pin from disengaging the sling attachment aperture of the threaded sling stud.
