Abstract
A device for assisting loading rounds into a firearm magazine (70) includes a body (12) that locks to the magazine using a catch pin 16. The body has a top opening (32) for a round (74). A press (40) hinged to the body top includes two plungers (44, 46) projecting down and aligned to enter the opening. A bullet pusher (60) is hinged to the body front and has a tongue (68) with a pushing surface (64). A wire (54) couples the press and pusher so that when the press is moved down, the pusher is moved out, and vice versa. A round is placed in the opening and on the tongue and the press is moved down to withdraw the tongue and push the round partly into the magazine. The pusher is then moved to the body to raise the press and push the round fully into the magazine.

DETAILED DESCRIPTION—FIGS. 1A-1C
(15)
(16) Body: The loader basically comprises body or holder 12 defined by four connecting side-walls and an open bottom and a partly-open top. The four walls consist of a back wall, a front wall, and two side walls connecting said front and back walls to form a rectangle. It is sized and configured to fit over the top open end, or side, of magazine 70 (
(17) Press: A tiltable top pusher or press 40 is hingedly coupled, at its rear or lower end, to and between support ears 22 by pin 52 (
(18) The press has a relatively long plunger 44 extending from its underside at its lower inner end downward substantially perpendicular to the press's underside surface (not numbered). The press also has a shorter front plunger 46 further up the press extending substantially parallel to plunger 44, also extending from its underside. A thin support rib 45 extends between the plungers for strength. Two stops or blocks 47 sandwich the proximal end of front plunger 46; when the plunger is rotated down these stops engage the top of the body to provide means for limiting the extent of the downward rotation of the press.
(19) Body 12 also includes body-locking or attaching means for removably attaching the body to the magazine. Such means comprises an outwardly flexible elastic magazine lock tongue 14 (
(20) Body 12 includes a rear hand support or grip 26 (seen best in
(21) Pusher: The loader has a front pusher 60 (best shown in
(22) Pusher 60 further has a projecting tongue 68 at its upper end that extends from the inner side of the pusher adjacent its upper end. The tongue has a free end that is spaced from a topmost round in said magazine when the pusher is in its open position and past the front wall and into the open end of the magazine so that it can engage and push an end of a topmost round in the magazine when the pusher is moved to the closed position. The tongue has a substantially vertical bullet-pushing surface 64 (better seen in
(23) A metal wire 54 (
(24)
(25) The loader's body, press, and front pusher are preferably made of durable glass-fibered polymer material, such as polyamide-6, and produced by plastic injection molding. Wire 54 is preferably made of spring wire or stainless-steel wire and the two pins are preferably made of metal for strength.

(40) Operation—
(41) The loader can be used to easily, quickly, and painlessly load ammunition rounds into a PMR/CMR-30 or similar magazine. Assume that the loader is in its open state, where front pusher 60 is pressed in, against the loader's body, and press 40 is moved up as shown in
(42) The loader will remain stably in either its open or closed state. If the loader is initially in its closed state, where press 40 is pushed down and pusher 60 is moved out, away from the body as shown in
(43) Assuming the loader is initially open, or has been opened by the step of the previous paragraph (
(44) The user then uses a finger (not shown) to move press 40 down. At first, when press 40 moves partly down (
(45) As the user moves press 40 further down, plunger 46 engages the upper or bullet end of case 76, pushing it down somewhat (
(46) When the first round drops or is pushed down into the magazine, it aligns on one side of the magazine (not shown) because the one side of the upper surface of the follower (not shown) is deeper than the other. Each subsequent round drops down on alternatingly opposite sides of the magazine to form two columns because the last previously loaded round is on one side or the other and thereby forms a receiving vacant space on the opposite side.
(47) The user's force on press 40 is multiplied or leveraged on the round because pushing plunger 44 is closer to the axis of rotation pin 52 of press 40 than the actual user's pressing point on the upper surface of the press—which is commonly further up the press. Hence, using the loader to push in rounds is easier than manual loading or loading with any prior-art loader because of leverage.
(48) Lastly, the user pushes pusher 60 back in with the thumb and simultaneously releases finger pressure on the press, causing bullet-pushing surface 64 of tongue 68 to push the bullet and hence the round back to a fully inserted position. When the round is pushed back, the tip of the bullet slides off top edge 70F of the magazine and the round moves fully below flap 73 and lip 72 into its rear-most and fully inserted position in the magazine. The round is now held in place by both lip 72 and flap 73 along either left or right side of the magazine, as illustrated in
(49) The user repeats these steps for loading additional rounds. The following is a brief summary of the steps:
(50) 1. Loader Open: If loader is initially closed, the user opens it by pressing pusher 60 toward body to open the loader and tilt press 40 upward, as shown in
(51) 2. Round Initially Inserted: After the loader is opened, or is initially open, the user inserts a new round, rear or rim end first, into opening 32 and onto the magazine where the bullet rests on tongue 68 of pusher 60. The round is initially inserted.
(52) 3. Round Intermediately Inserted: Then the user releases pressure on pusher 60 and pushes press 40 down, thereby pushing the rim end of the round further down into the magazine while simultaneously moving the pusher away from the body to allow the bullet to drop down from tongue 68 to rest atop edge 70F of the magazine. The round is now in an intermediate partly inserted position below a flap 73 of the magazine.
(53) 4. Round Fully Inserted: The user releases pressure on press 40 and forces pusher 60 back toward the body and opens press 40. The free end surface 64 of tongue 68 pushes the tip of the bullet and hence the round rearward into its fully inserted rear position below a lip and flap of the magazine.
(54) 5. Repeat To Load Rest of Rounds: The user continually repeats the last three steps until the magazine is fully loaded with rounds. With some practice, the user can load rounds quickly and easily by repeatedly cycling from open to round fully inserted positions, until the magazine is full.
(55) Use of the loader eliminates the need to load up to 30 rounds with bare-fingers under increasing manual force from the spring in the magazine. Thus, the loader eliminates fatigue and accumulated finger pain.
(56) To remove the loader from the magazine, the user simply (a) pulls with one hand the top side of lock tongue 14 outward to disengage lock tooth 16 from the magazine's top witness hole 71, and (b) pushes and slides the loader upward away from the magazine with the other hand.
CONCLUSION, RAMIFICATIONS, AND SCOPE
(57) The reader will see that we have provided a magazine loader that can be locked to the magazine for stability and reliable operation. It has two easily operable members which use leverage. It provides a valuable aid to load magazines of the type which have feed lips or feed lips with retaining flaps. The user can load multiple magazines without any thumb pain associated with directly repeatedly pushing new rounds into the magazine. The loader comprises few parts, is highly reliable, comfortable to use, palm-sized, light weight, and simple to operate.
(58) While the above description contains many specificities, the reader should not construe these as limitations on the scope but rather as an exemplification of several embodiments thereof. Other ramifications and variations are possible within the teachings.
(59) Some exemplary ramifications are as follows: The loader described can be altered to fit other magazines and calibers, provided a suitable change in dimensions and construction is made in the loader to suit a magazine. The loader and its components may be made of separate and or different plastic materials, or, alternatively, of other materials, such as aluminum or steel, and any combination thereof. All numerical values provided are approximate; they can be changed to adapt to other magazines or round types and or calibers. Coupling wire 54 can be supplemented with an additional coupling wire on the other side, or by lever arm(s). The shapes of plungers 44 and 46, as well as all other parts, can be changed to other configurations. The press may have just one plunger extending therefrom for pushing a round down. The loader may be useable on magazines without retaining flaps.
(60) Accordingly, the scope should be determined, not by the embodiments illustrated, but by the appended claims and their legal equivalents.
