Description

FIELD OF THE INVENTION

This invention relates to charging handles for firearms, in particular, ambidextrous charging handles.

BACKGROUND

Semi-automatic rifles are used by shooters that are left handed, right handed, or ambidextrous. For reliability and ease of use, it is advantageous to accommodate all shooters by implementing rifle designs which emphasize ambidextrous features.

The charging handle is central to the operation of the semi-automatic rifle, as its action draws the bolt out of battery. This action allows the shooter to open the breech and eject spent cartridges from the chamber and load a new round from the magazine. Opening the breech also allows the shooter to verify the chamber is clear of rounds or obstructions and/or clear any stoppages before moving the bolt back into battery. To operate the charging handle, the shooter controls the rifle by holding the grip or forestock of the firearm with one hand while maneuvering the charging handle with the other hand.

There is clearly an opportunity to improve the charging handles of rifles to accommodate left and right handed shooters.

DETAILED DESCRIPTION

FIGS. 1 and 2 show an example semi-automatic rifle 10 having a receiver 12. The receiver 12 defines an interior space which houses a charging handle assembly 20 and a bolt 30. The example charging handle assembly 20 includes a first handle 22 and a second handle 24 extending outwardly away from the right and left sides of the receiver 12, respectively. The handles 22, 24 extend through slots 14, 16 in a first side 13 and a second side 15 in the receiver 12. The slots 14, 16 are elongated to allow the handles 22, 24 to slide within the slots 14, 16 along a longitudinal axis 18.

FIGS. 3 and 4 show an example charging handle assembly 20 according to the invention. The charging handle assembly 20 includes a body 26 extending along a first axis 50 oriented transversely to the longitudinal axis 18. The charging handle assembly 20 includes a first side 21 configured to connect to the first handle 22. The charging handle assembly 20 includes a second side 23 configured to connect to the second handle 24. The first handle 22 and the second handle 24 extend out from the body 26 along the first axis 50 providing the shooter quick and easy access to engage the charging handle 20. The first handle 22 and second handle 24 may be removably connected via various types of mechanical joints. For example, the mechanical joint may be a doweled butt joint, a dado joint, a rabbet joint, a dovetail joint, a miter with spline joint, a lap joint, a mortise and tenon joint, or a tongue and groove joint. The first handle 22 and second handle 24 may be removably connected to the first side 21 and second side 23 of the body 26 via male female joints 25, 27. As shown in FIG. 3, the first handle 22 and second handle 24 may be attached to the first side 21 and the second side 23 via dovetail joints 29, 31. Alternatively as shown in FIG. 4, the first handle 22 and second handle 24 may be attached to the first side 21 and the second side 23 via geometrically corresponding protrusions and recesses 35, 37 (e.g., with the recesses configured to complementarily receive respective, corresponding protrusions).

As shown in FIG. 5A, alternatively or in addition, the first handle 22 and the second handle 24 may be removably connected to the first side 21 and the second side 23 with fasteners 52 (e.g., set screws or similar fasteners). The first handle 22 and the second handle 24 may include axially threaded openings to receive the set screws 52. The first side 21 and the second side 23 may each include a recessed pocket 51 configured to bed the set screw 52 to assist in aligning the first handle 22 and the second handle 24 to the body 26 upon assembly. As shown in FIG. 5B, alternatively or in addition, the first handle 22 and the second handle 24 may be removably connected to the first side 21 and the second side 23 with fasteners 54, such as screws. The body 26 may include threaded openings 55 to receive the fasteners 54. The first handle 22 and the second handle 24 may be completely removed when the rifle 10 is not in use to improve carrying and transportation conditions. As shown in FIGS. 5A and 5B, the first handle 22 and the second handle 24 may be offset from each other along a vertical axis 70. The slots 14, 16 may have different heights to accommodate the location and offset nature of the first handle 22 and second handle 24.

The body 26 also includes an opening 28 configured to receive a rod 40. The rod 40 extends through the opening 28 along the longitudinal axis 18. The rod 40 includes a first end 46 and a second end 48. The body 26 is configured to move along the rod 40 between the first end 46 and the second end 48. The rod 40 extends through the center of a return spring 42. The return spring 42 acts between the first end 46 and the body 26 thereby biasing the body 26 towards the second end 48 of the rod 40. The body 26 is configured to move along the rod 40 (and, thus, along the longitudinal axis 18). As the body 26 move towards the first end 46 of the rod 40, the body 26 compresses the return spring 42. Optionally, the second handle 24 may be offset from the first handle 22 along the vertical axis 70. For example, as shown in FIGS. 5A-5B, the second handle 24 may be positioned higher along the vertical axis 70, to provide more support and stability at a position near the rod 40.

As shown in FIG. 6, the body 26 of the charging handle 20 may be mounted within a recess 33 defined by the bolt 30. The body 26 moves the bolt 30 along the longitudinal axis 18 when the body 26 moves along the rod 40.

As shown in FIG. 6, the charging handle assembly 20 and the bolt 30 are mounted within the receiver 12. In some examples, the combination of the charging handle assembly 20, the bolt 30, and the receiver 12 are referred to herein as a “receiver assembly,” with the charging handle assembly being referred to as a “charging handle subassembly” for clarity. The charging handle assembly 20 and the bolt 30 are housed within a receiving area 11 defined by a first end 60, a second end 62, the first side 13, and the second side 15. The first end 46 of the rod 40 engages with the first end 60 of the receiver 12. The first end 60 of the receiver 12 and the opening 28 within the body 26 brace the rod 40 within the receiver 12. As shown in FIG. 6, the return spring 42 biases the body 26 of the charging handle assembly 20 and the bolt 30 mounted to the body 26 towards the second end 62 of the receiver 12 thereby positioning the bolt 30 into battery.

When the first handle 22 or second handle 24 of the charging handle assembly 20 is pulled by a shooter, the body 26, and therefore, the bolt 30, move along the longitudinal axis 18 towards the first end 60 of the receiver 12 compressing the return spring 42. As shown in FIG. 7, as the body 26 moves to the first end 60 of the receiver 12, it draws the bolt 30 out of battery. This action allows a shooter to open the breech and eject spent rounds. This action also allows a shooter to load a new round from a magazine. When a new magazine is loaded, the first handle 22 or second handle 24 is pulled and then subsequently released. After the charging handle 20 is released, the return spring 42 biases the bolt 30 towards the second end 62 of the receiver 12 back into battery, stripping and chambering a new round from a magazine.

Because the first handle 22 extends from the right side of the receiver 12 and the second handle 24 extends from the left side of the receiver 12, a shooter may hold the grip or forestock of the rifle 10 with either the left or right hand while using the other hand to pull the charging handle 20 via the first handle 22 or the second handle 24. This feature thereby accommodates left and right handed shooters by allowing shooters having either right or left hand dominance to open the breech and/or load a new round from a magazine.

It is expected that the example charging handle assembly 20 according to the invention will improve ease and reliability of a rifle for left and right handed shooters.

All of the embodiments of the claimed invention described herein are provided expressly by way of example only. Innumerable variations and modifications may be made to the example embodiments described herein without departing from the concept of this disclosure. Additionally, the scope of this disclosure is intended to encompass any and all modifications and combinations of all elements, features, and aspects described in the specification and claims, and shown in the drawings.
