The main body 11 can act to receive a rifle firing mechanism 1 (see FIG. 1b), and to function as a forearm stock for providing a safe grip for the forward hand of a user when operating the rifle. In the embodiment (both parts), the main body can include an elongated member having a front end 11a, a back end 11b, and a pair of opposing generally parallel side walls 11d (FIG. 1b) and 11c (FIG. 2) that are joined together by a bottom wall 11e (FIG. 1b) to form a generally U shaped longitudinal channel along the main body.

A pivot housing can be disposed along the back end of the main body 11 and can be defined by an upper surface 11f (FIG. 2) blending into the top end of the side walls, the upper portion of the removable grip 15 (FIG. 1b) and walls 11c, 11d, 11b, and 11b1 (FIG. 2). Each of these surfaces forming a generally cavernous space into which the pivot assembly 30 can be located.

The top surface of the bottom wall 11e (FIG. 1b) can include a plurality of raised sections relative to the upper portions of the side walls 11c (FIGS. 6) and 11d (FIG. 1b). In one embodiment, the upper side of the bottom wall can include a first raised section 11e1 (FIG. 5) for receiving a rifle barrel, a second raised section 11e2 (FIG. 2) extending below a received rifle barrel, and a third raised section 11e3 (FIG. 5) for receiving the connector of the firing mechanism. A bolt opening 11e4 (FIG. 4) can be positioned within the third raised section 11e3 of the bottom wall and positioned so as to receive a bolt for securing the main body into the connector of the firing mechanism.

As shown in FIG. 2, a firing mechanism opening 12 extends from the edge of the third raised section 11e3 to the forward wall of the pivot housing 11b1. Opening 12 can also include a ridge 12a having a shape that is complementary to the ridge of the firing mechanism (see FIG. 5), so as to provide a shelf onto which the firing mechanism can be secured.

As shown in FIG. 1a, a removable hand grip 15 can be positioned along the bottom of the main body 11e at a location beneath the pivot housing. As shown, the grip can be secured to the main body via a bolt 15a and bolt receiver 15b, and can further include a rough surface area for increasing traction with the hand of a user, and a plurality of finger ridges 15c. An opening 15d along the bottom of the grip allows the bolt to be accessed at all times to enable a user to quickly change the grip.

Each of the main body 11 and the hand grip 15 can be constructed from any number of strong, impact resistant materials such as wood, metals or plastic, for example, capable of withstanding the rigors of weapon usage. In one preferred embodiment, the ridge 12a can be integrated into the construction of the opening 12, in accordance with known construction methodologies (see FIG. 1b).

As shown in FIG. 2, the elongated stock 20 can include a pair of laterally spaced elongated arms 21 and 22, each having a first end 21a and 22a and a second end 21b and 22b, respectively. A generally U-shaped butt stock 23 can be secured to the second end of each arm via a pair of axel pins 24 to allow the butt stock to pivot, see arrow a, between a generally vertical open position and a generally horizontal closed position.

In one embodiment, the elongated stock 20 can be secured to the back end of the main body so as to pivot from an open position to a closed position. In one preferred embodiment, the locking pivot assembly 30 described below can be utilized; however it is to be understood that any suitable device capable of transitioning the elongated stock between an open position and a closed position can be utilized herein.

As shown in FIG. 3, illustrates one embodiment of a pivot assembly for use herein. As shown, the pivot assembly 30 can include an axel 31, a button spring 32, a button 33, a split pin 34, a lock pin 35, a washer 36, and a retaining ring 37.

As shown in FIG. 3, shows that axel 31 can include an elongated hollow shaft having an outside dimension suitable for being inserted through the hole 21a1 of the stock arm 21, and a hollow inside dimension suitable for receiving the button spring 32 and button 33. The button spring 32 can be positioned within the hollow portion of the axel and can receive the button 33 on one end.

As shown in FIG. 3, the split pin 34 can be inserted through openings 31a and 33a of the axel and button respectively, to prevent separation of the components. As such, the upper portion of the split pin 34 can be positioned flush with the upper portion of the axel, and the lower portion of the split pin can extend from the bottom of the axel. The extended portion of the split pin being configured to be inserted into the opening 35a of the locking pin 35.

As shown in FIG. 3, the main body 11 can include a generally circular hollow channel 19 having a suitable inside dimension for receiving the axel 21. A second hollow channel 19a is blended into the lowermost portion of the channel 19 and includes a dimension suitable for receiving the locking pin 35. To this end, the axel 31 having the spring 32, the button 33 and the split pin 34 are inserted through the opening 21a1 of the stock arm 21 and into the opening 19. Likewise, the locking pin 35 is inserted into the opening 19a. As the axel includes a first end having an enlarged faceplate 31b with a dimension that is greater than opening 21a1, the axel remains within the opening 19.

As shown in FIG. 3, when so positioned, the second end of the axel 31c will extend out of the channel 19 and through opening 22a1 of the second stock arm 22 and the washer 36. A small grove 31c1 is disposed along a periphery of the second side of the axel, and acts to receive a retaining ring 37 to lock the assembly into place.

In operation, when the button 33 is pressed, the split pin 34 moves the lock pin 35 out of position, and allows the stock arms 21 and 22 to rotate around the axel. When the button 33 is released, the button spring 32 will place outward pressure on lock pin 35 through the button 33 and the split pin 34. When the stock arms 21 and 22 are rotated to a fully open position or a fully closed position, the lock pin 35 slides into position and secures the assembly in place. Accordingly, the assembly 30 acts to allow a user to rotate the stock arms a full 180 degrees between an open position (FIG. 2) and a closed position (FIG. 6) and to automatically lock the same.

FIG. 4 illustrates the under folding firearm stock assembly 10 transition from the open position to a closed position, wherein the stock arms 21 and 22 are rotated 180 degrees, see arrow b, about the pivot assembly until being positioned alongside main body side walls lid and lie, respectively. When so positioned, the butt stock 23 can be rotated to a closed position (see arrow a), so as to rest directly beneath the bottom wall of the main body 11e. When so located, the locking member of the pivot assembly can engage the openings, so as to prevent the arms from moving, as described above.

FIG. 5 and FIG. 6 illustrate one embodiment of the under folding firearm stock assembly 10 in operation with the firing mechanism of a rifle. As shown, the rifle firing mechanism 1 can include a factory barrel 2, receiver 3, cartridge receiver 4, trigger guard assembly 5, bolt 6, and bolt operating handle 7. A ridge R separates the upper portion of the trigger guard assembly 5 and the lower portion of the receiver 4, and a stock connector 8 is positioned beneath the barrel at a location adjacent to the cartridge receiver. The stock connector including a threaded opening 8a for allowing the rifle stock to be bolted to the firing mechanism. These and other components of the rifle firing mechanism are described in U.S. Pat. No. 7,302,881, to Tertin, the contents of which are incorporated herein by reference.

Accordingly, the shape of the firing mechanism opening 12 of the main body conforms to the shape of firing mechanism 1 so as to allow the lowermost portions of the trigger assembly 5 and the cartridge receiver 4 to penetrate the opening 12 and be positioned beneath the bottom wall of the main body 11e. Additionally, the ridge 12a, the third raised section 11e3, and the first raised section 11e1 can act as a shelf upon which the ridge R, the stock connector 8 and the barrel 2 of the firing mechanism can rest, respectively. When so positioned, bolt opening 11e4 of the third raised section, and threaded opening 8a of the stock connector can be aligned so as to receive a bolt (not illustrated) for securing the firing mechanism 1 into the under folding firearm stock assembly 10. (See FIG. 5)
