DETAILED DESCRIPTION
(18) In accordance with the present disclosure, embodiments of a firearm cartridge magazine loading optimization device are presented. Generally, the firearm cartridge magazine loading optimization device, as presented in the various embodiments described herein, is a device for automatically loading cartridges into magazines and eliminates the need for a user to hand load the same. FIGS. 1-2 depicts a magazine loading device 10 according to a first example embodiment of the present disclosure. As detailed in FIG. 1, the magazine loading device 10 generally includes an ammunition hopper 20, elevator conveyer 30, projectile indexer 40, load bay 50, battery source 60, and logic board 70. The example embodiment depicted in FIGS. 1-2 is configured to receive ammunition designed for the AR-15 rifle, such as 223 Remington and/or 5.56 NATO, but in alternative embodiments, the magazine loading device of the present disclosure can be configured to receive any other type/size of ammunition or can be configured to accept and operate with any other weapons platform (such as AK-47, other rifles, pistols, or shotguns).
(19) As shown in FIGS. 1-2, an exemplary magazine loading device 10 includes an ammunition hopper 20 for receiving cartridges. A user utilizing the exemplary magazine loading device 10, can insert a quantity of cartridges into the ammunition hopper 20. In particular, the ammunition hopper 20 can receive the load ammunition in various quantities and no specific orientation of the cartridges is required when loading the ammunition. For instance, a user can simply open a container of ammunition and pour the cartridges into the ammunition hopper 20 without regard to quantity or orientation. The ammunition hopper 20 is coupled to the elevator conveyor 30 and is preferably oriented at an angle Al such that the loaded ammunition slides along a slide surface 22 (best seen in FIG. 3) via gravity toward the elevator conveyor 30. In example embodiments, angle Al is less than 90 degrees from vertical, and in alternative example embodiments, angle Al is less than 75 degrees from vertical. The slide surface 22 in exemplary embodiments includes rails 24 to prevent cartridges from escaping the ammunition hopper 22 and to help funnel the cartridges towards the elevator conveyor 30. Optionally, the rails 24 can also agitate the cartridges in the hopper 20 to help facilitate the self-loading nature of the cartridges into the conveyor 30. In commercial example embodiments, the ammunition hopper is made from metal (such as aluminum or steel, or variations thereof) but can alternatively be constructed from plastic, polymers, wood, rubber, other metals, or as otherwise desired by a user.
(20) In example embodiments, the elevator conveyor 30 is affixed to a base 12 and rises at a perpendicular, or substantially perpendicular, orientation therefrom. The elevator conveyor is motor-driven to transport the cartridges in the ammunition hopper 20 to the projectile indexer 40 and includes one or more fins 32 positioned along the circumference of the conveyor to engage and lift the cartridges from the ammunition hopper 20 to the projectile indexer 40, as shown in FIGS. 1-2 and 4. In example embodiments, the fins 32 are sized to receive a particular cartridge size (e.g., AR-15 ammunition) and are removably coupled into place along the conveyor 30. In example commercial embodiments, the fins 32 are clipped into place, but alternative known coupling methods can be used to removably affix the fins to the conveyor 30. Additionally, a user can utilize any number of fin sizes/shapes (e.g., having various lengths and/or widths), such that the magazine loading device 10 is modular and can be configured to receive various types of ammunition having alternative shapes and sizes (for instance, pistol cartridges, shotgun cartridges, or various other types of rifle cartridges). In still other alternative embodiments, the fins 32 can be permanently affixed to the conveyor 30. The elevator conveyor 30 also can include side rails 34 (as best seen in FIG. 4) for containing and restricting the cartridges along the carrying surface 36 of the elevator conveyor 30. The elevator conveyor 30 lifts the cartridges, one at a time, from the ammunition hopper 20 and deposits each of them in the projectile indexer 40.
(21) An exemplary projectile indexer 40, as best seen in FIGS. 1-2 and 5, is coupled to the base surface 12 via its indexing base 48 and is adapted to receive the cartridges from the elevator conveyor 30 as they are carried away from the ammunition hopper 20. When a cartridge reaches the top of the elevator conveyor 30, it is deposited into projectile indexer 40 via the uppermost opening 42 of the projectile indexer's indexing tray 41. As best seen in FIGS. 5a-5c, once inside the projectile indexer 40, the cartridges pass through a slot 43 having the general shape of the particular cartridge that the magazine loading device 10 is configured to receive. For instance, if the magazine loading device 10 is configured to receive 223 Remington, the projectile indexer 40 can include an indexing tray 41 that includes a slot 43 that generally mirrors the bullet shape of the 223 Remington cartridge and sized such that an actual 223 Remington cartridge can pass therethrough, regardless of the orientation of the cartridge when it is deposited into the indexing tray 42. As best seen in FIG. 5a, in example embodiments, the slot 43 has bullet shaped openings at each end to permit a cartridge to slide through the slot in a bullet-down orientation before sliding through an opening 45a in a bottom 45 of the feed chute 44 and into the actuator housing 46. The projectile indexer 40 includes a cavity 47 adapted for receiving a magazine therein. The projectile indexer 40 also includes a mating surface 49 for removably engaging the load bay 50. In example embodiments, the actuator housing 46 encloses one or more actuators 80 (example actuators seen in FIG. 9) for engaging the cartridge and pushing each individual cartridge into a magazine, which is removably coupled thereto.
(22) In example embodiments the load bay 50 is proximally located near the projectile indexer 40, and in particular, the mating surface 49 of the projectile indexer generally abuts the adjoining surface 52 of the load bay. As best seen in FIGS. 1-2 and 6, the load bay 50 includes a mounting base 54 for affixing the load bay to the base surface 12 and positionally securing the load base in relation to the projectile indexer. In this orientation, the cavity 47 of the projectile indexer 40 is aligned with a corresponding cavity 56 in the load bay, and collectively, the two aligned cavities create a receiving port 58 for receiving and temporarily securing a firearm magazine, such as the AR-15 magazine 90 depicted in FIG. 7. In example embodiments, the load bay 50, actuator housing 46, projectile indexer 40 and tray 41 are interchangeable to accommodate a wide variety of firearm platforms and cartridges types/sizes. Example embodiments described herein that are directed towards receiving ammunition for an AR-15 rifle are merely exemplary.
(23) Additional components used in connection with example embodiments of the present disclosure are depicted in FIGS. 8 and 10-12. For instance, FIG. 8 depicts exemplary components from Vex Manufacturing, such as, but not limited to, example electric motors 91, example gears 92, and example tread kits 93. FIG. 10 depicts an example battery 94, which in example embodiments is a sealed lead acid battery used to power all electrical components of the magazine loading device 10. FIG. 11 depicts example sensors 95 for use with the indexing tray 41 to prevent more than one cartridge from being loaded in the tray at one time. In example embodiments, the sensors used in connection with example embodiments of the present disclosure are infrared break beam sensors. FIG. 12 is an example logic board 96 for use with example embodiments according to the present disclosure, which contains all programming logic to control the operation of the magazine loading device 10. Finally, a housing 100 can be used to cover the at least a portion of the working components of the magazine loading device 10 as seen in FIG. 13.
(24) In operation, example embodiments of the magazine loading device 10 according to the present disclosure can be operated in the following sequence. First, a user can insert and orient a magazine, such as the example magazine 90 as depicted in FIG. 7, into the receiving port 58. Then, a user can place the desired ammunition into the ammunition hopper 20 and can power on the machine by connecting the power source to the motor (this can be accomplished mechanically or by utilizing an on/off switch) and allowing the elevator conveyor 30 to ferry cartridges towards the projectile indexer 40. As soon as the first cartridge is deposited into the projectile indexer 40 via the indexing tray 41, the elevator conveyor 30 is temporarily halted until the first cartridge has been inserted into the magazine so as not to jam the magazine loading device 10. The aforementioned temporary halting of the elevator conveyor can be accomplished either mechanically by the user/operator or automatically via one or more sensors, such as those sensors 95 depicted in FIG. 11. Once the cartridge has been indexed by the projectile indexer 40 and is oriented in the correct direction, an actuator (such as, for example, the one depicted in FIG. 9) engages the cartridge and loads the same into the magazine. The magazine is sequentially loaded in this fashion until the magazine is full, at which time, the user can switch out a full magazine for an empty magazine and restart the process.
(25) It should be emphasized that the above-described embodiments of the present disclosure are merely possible examples of implementations, merely set forth for a clear understanding of the principles of the disclosure. Many variations and modifications may be made to the above-described embodiment(s) without departing substantially from the principles of the disclosure. All such modifications and variations are intended to be included herein within the scope of this disclosure and protected by the following claims.
