PISTOL MAGAZINE LOADER
A pistol magazine loading assistance tool can include a handle having a substantially planar front surface for retaining the back of a magazine, an adjustable clamp portion for engaging the bottom of the magazine, an angled upper ledge extending toward the front of the magazine, and a reverse hinge lever pivotally mounted on the front portion of the angled upper ledge, the reverse hinge lever having a downwardly extending plunger on its bottom surface for contacting the top surface of a round adjacent the backend of the round.
This application claims priority to U.S. Provisional Patent Application No. 61/932,719 filed Jan. 28, 2014, which is hereby incorporated herein by reference in its entirety.
TECHNICAL FIELDThe present application is directed to a pistol magazine loader that can be used with a variety of pistol magazines of different dimensions for holding pistol rounds of different dimensions and calibers.
BACKGROUNDMany pistols can fire multiple rounds of ammunition (also known as cartridges) in fairly rapid succession when the rounds are held in interchangeable magazines. Each magazine is ejected from the pistol after it is emptied of rounds and a loaded magazine (either the original magazine reloaded or another loaded magazine) is then inserted into the pistol. Each of the rounds is substantially elongated and comprises a deep cuplike case (also known as a shell casing and sometimes also called a cartridge), usually made of brass, which is filled with an explosive propellant. At its rear or closed end, the case has a rim or flange containing a primer. The front end, opposite the primer end, of the case is open. A bullet, slug, or head, usually of lead (optionally jacketed) is partially inserted into the open or front end of the case by crimping the case onto the bullet.
For semi-automatic pistols, the rounds are held within and fed into the firearm from a pistol magazine, which typically is inserted upwardly into the grip portion of the pistol. Detachable pistol magazines, also sometimes referred to as “clips,” have become the industry standard throughout the world. Pistol magazines typically are elongated containers having a generally rectangular cross-section and are commonly made of aluminum alloys, plastic, steel, or a combination. They are usually closed on five sides and open on a sixth, upwardly facing, top side, and are substantially hollow. The top or open side has a rectangular opening and includes two round-retaining members, known as feed lips, which project into the opening and act as a stop for the rounds so that they are not expelled from the top of the magazine. Pistol magazines have an internal spring which urges a follower or pusher (a shaped piece of plastic or metal) toward the open side. The follower in turn urges the rounds as a group up against the lips. Rounds are stacked or oriented in the magazine such that the longitudinal axes of the rounds are substantially parallel and perpendicular to the direction of travel of the spring and follower. Adjoining rounds are oriented side-by-side, i.e., the bullet ends of adjacent rounds are next to each other and face the front wall of the magazine. The case ends of the rounds are also oriented in a similar side-by-side fashion with the primer end facing the back wall of the magazine. The rounds are usually stacked in the magazine, either in a single straight column or in a staggered (zigzag) column (also called double-stacked or high-capacity) fashion. The latter magazines, being wider, achieve higher round capacity compared to single-column magazines of the same overall length. In typical pistol magazines, the space between the retaining lips is smaller than the case diameter of the rounds so that the two lips of the magazine hold the topmost round. For purpose of this application, the term ‘magazine’ will mean pistol magazines where two lips retain the topmost round.
Prior to its use, a pistol magazine must be loaded or filled with rounds. When a pistol magazine is being loaded, it is necessary to depress all of the previously loaded rounds to provide vacant space below the lips so an additional round can be inserted or loaded into this space. Each time another round is loaded the magazine's spring is further compressed, requiring more insertion force for each successive round. When a magazine is fully loaded, the spring is fully compressed and exerts maximum upward force against the follower and rounds towards the lips. Loading magazines is relatively time-consuming, tedious, and can be a painful practice when done with bare fingers. The process becomes increasingly uncomfortable for the loader's fingers as more rounds are loaded against the increasing spring pressure, thus slowing the loading process. When multiple magazines are to be loaded with the user's bare hands, much time is required, and user's fingers are often rubbed raw. In combat circumstances, slow reloading of pistol magazines could become a life-threatening situation.
To increase loading speed and decrease finger pain, numerous magazine loaders have been designed. The market includes many different pistol magazines, which differ in their round capacity, length, width, depth, round caliber, materials, adaptability to match magazine wells, shape of lips, and magazine locking or latching mechanism. Many pistol designs have their own unique magazine. Therefore, to accommodate the extremely wide range of magazines with all their mechanical variations, manufacturers of magazine loaders had to manufacture a variety of pistol magazine loaders to accommodate guns, magazines, and rounds of different dimensions and calibers. One example of the variety of loaders necessary to accommodate different magazine pistols is the family of three different size loaders from ADCO Sales Inc., sold under the trademark Super Thumb models ST1, ST2 and ST3. Another type of loader is the complex ratchet and pall back end lever design shown in U.S. Pat. Nos. 5,249,386 and 5,377,436 to Switzer and sold under the trademark HKS. The HKS family of loaders has different overall sizes and a magazine length adjuster or fitter to accommodate multiple different magazines. Despite the use of such adjusters, HKS currently offers ten different pistol magazine loaders to account for the differing dimensions of the most commonly used magazines in the market.
SUMMARYA pistol magazine loading assistance tool can include a handle having a substantially planar front surface for retaining the back of the magazine; an adjustable clamp portion for engaging the bottom of the magazine; an angled upper ledge extending toward the front of the magazine; and a reverse hinge lever pivotally mounted on the front portion of the angled upper ledge; the reverse hinge lever having a downwardly extending plunger on its bottom surface for contacting the top surface of the round adjacent the backend of the round. Preferably, the tool further includes an adjustable threaded knob for allowing movement of the clamp portion along the length of the handle of the tool and the handle further includes a clamp cut out portion dimensioned for receipt of a threaded bolt extending therethrough. The threaded knob and clamp can be slid along the length of the clamp cut out in order to engage the bottom of pistol magazines of a wide variety of different heights so that magazines of different dimension can be accommodated by the loader. It is also preferred that the handle include a plurality of magnetic inserts that are dimensioned for mounting on the front surface of the handle to assist in retaining the back of the magazine against the handle.
In an alternate embodiment, a pistol magazine loading tool is provided for use with a pistol magazine having a front wall, bottom wall, pair of side walls, back wall, and an open top end with a pair of round retaining lips extend from the side walls adjacent to the back wall of the magazine, the loading tool includes: a handle for retaining the back wall of the magazine; an adjustable clamp portion for contacting the bottom surface of the magazine; an angled upper ledge extending toward the front of the magazine; the angled upper ledge having an elongated plunger cut out portion; and a reverse hinge lever having (a) a first end pivotally mounted on the front end of the angled upper ledge adjacent to the upper front wall of the magazine, (b) a plunger portion extending from the bottom surface of the lever for contacting the upper surface of a round, the plunger portion being dimensioned to extend through the plunger cut out portion of the angled upper ledge during the loading of a round, and (c) a second end with a substantially planar upper surface for allowing the user to press downwardly on the reverse hinge lever during loading. The lower surface of the angled upper ledge engages at least the back wall at the open top end of the magazine to assist in retaining the magazine in the clip during loading. The plunger of the reverse hinge lever being dimensioned such that, when downwardly pivoted into contact with the follower of a magazine retained under the angled upper ledge, the front surface of the plunger is spaced back from the front wall of the magazine a distance sufficient to allow insertion of at least the back end of the round beneath the pair of feed lips.
In another embodiment, an improved method of loading a pistol magazine is provided, including the steps of: (1) providing an empty pistol magazine having a front wall, bottom wall, pair of side walls, back wall and an open top with a pair of retaining lips extending inwardly from the sidewalls adjacent to the back end of the magazine; (2) providing a pistol magazine loader including (a) a handle for retaining the back wall of the magazine; (b) an adjustable clamp portion for contacting the bottom surface of the magazine, (c) an angled upper ledge extending toward the front of the magazine; (d) a reverse hinge lever with (i) a first end pivotally mounted on the front end of the angled upper ledge adjacent to the upper front wall of the magazine, (ii) a plunger portion extending from the bottom surface of the lever for contacting the upper surface of a round, and (iii) a second end with an upper surface for pressing downwardly on the reverse hinge lever during loading; 3) mounting an empty pistol magazine within the loader by (a) placing the upper surface of the back wall of the magazine against the angled upper ledge; (b) placing the outer surface of the magazine back wall against the handle of the loader; (c) sliding the adjustable clamp portion into contact with the bottom wall of the magazine and (d) detachably securing the clamp portion firmly against the bottom wall of the magazine; (4) depressing the upper surface of the reverse hinge lever causing downward pivoting of the plunger of the reverse hinge lever to depress the magazine follower and create a round loading space defined by the back surface of the front wall of the magazine, the front surface of plunger portion of the reverse hinge lever; the top surface of the depressed magazine follower and the undersides of the front portion of the feed lips; (5) inserting the back end of a round into the round loading space; (6) pushing on the front end of the inserted round causing the back end of the round to slide under the feed lips and move into contact with the back wall of the magazine adjacent the back end of the feed lips, the pushing on the front end of the round causing the rear end of the round to contact the front surface of the plunger and thereby cause the reverse hinge lever to pivot upwardly into a pre-round loading position; (7) pushing downwardly on the upper surface of the reverse hinge lever to pivot the plunger into contact with the upper surface of the previously loaded round to create a second round loading space defined by the back surface of the front wall of the magazine, the front surface of the plunger of the reverse hinge lever, the front portion of the top surface of the depressed, previously loaded round, and the front portion of the pair of feed lips; (8) inserting the back end of a second round into the second round loading space; and (9) pushing on the front end of the second inserted round to cause the back end of the round to slide under the feed lips until reaching the back wall of the magazine adjacent the back end of the feed lips, the pushing of the second round causing the rear end of the second inserted round to contact the front surface of the plunger so that the reverse hinge lever pivots upwardly into the pre-round loading position.

The clamp 40 can be upwardly angled in order to accommodate the angled bottom wall 82 that is typical of the vast majority of pistol magazine. The clamp 40 can be formed from ⅛ inch thick aluminum plate stock and can be bent forward on its bottom end to form an angled bracket 44 and planar mounting portion 45. Other light weight durable metals such as alloys of steel, plastic polymer or carbon fiber may be used to form the clamp 40. Alternately, the clamp 40 may be injection molded from a high strength, durable plastic resin or may be metal injection molded from a suitable formable metal/plastic powdered resin material. The clamp 40 can be mounted through clamp cut out 22 formed in the lower portion of the handle 20. The clamp cut 22 can be machined from the handle 20 portion using a CNC cutting device with the cutout ranging from about 3.250 inches to about 2.5 inches in length, for example, so that the clamp 40 can have an adjustable magazine height travel distance of between about 0.0 and about 3.250 inches, for example. This can allow the loader 10 to accommodate pistol magazines having heights ranging between about 2.750 and 5.375 inches, for example. The 3.250 inch magazine height travel distance is sufficient to accommodate the vast majority of pistol magazines for ammunition rounds of .380 caliber to .45 caliber. The clamp 40 can be mounted to the handle through the clamp cut out 22 via threaded bolt 42 and threaded knob 41. The bolt 42 can be a socket head cap screw that can be permanently affixed to the clamp 40. The knob 41 can be made of a thermoplastic resin with an internal threaded nut (not shown) embedded therein. The knob 41 can be formed by injection molding the knob 41 portion around the threaded nut which can be inserted into the mold cavity prior to injection of the resin. Steel washer 47 can be placed between knob 41 and back surface 29 of handle to prevent abrasion of the knob 41.
Example details of the reverse hinge lever 50 can best be seen in
Hinge lever 50 can further include a narrow stem portion 55 that can extend between the hinge leaf portion 59 on a first end and thumb pad 54 on its second end. As best seen in
Pistol magazine 80 can be of generally rectangular construction with an angled bottom wall 82 and an upper surface 83. As best seen in
Prior to its use, pistol magazine 80 can be loaded or filled with rounds 70a,b. When a pistol magazine is being loaded, it may be necessary to depress all of the previously loaded rounds to provide vacant space below the lips so an additional round can be inserted or loaded into the vacated lip space. Each time another round is loaded, the magazine's spring is further compressed, which may require more insertion force for each successive round in such systems. When a magazine is fully loaded, the spring can be fully compressed and can exert maximum upward force against the follower and rounds towards the lips. Loading pistol magazines with the loader 10 can be quick, easy, and pain free for the user.
To use the pistol magazine loader 10, an empty pistol magazine can first be installed within the loader 10 by placing the upper surface 83 of the back wall 81 of the magazine 80 against the angled upper ledge 30 of the handle 20. Prior to this step, the user can ensure that the bracket 44 of clamp 40 is slid downwardly a sufficient distance along the length of clamp cut out 22 to allow the magazine 80 to fit between the angled upper ledge 30 and bracket 44. The back wall 81 of the magazine 80 can then be pivoted down into contact with the front surface of the handle of the loader, which can cause the magnetic inserts 23a-d to magnetically attract the metallic back wall 81 of the magazine 80. That magnetic attractive force can assist in holding the magazine 80 in place during the entire loading process, but may be particularly helpful prior to tightening of the bracket 44 of the clamp 40 in its final position. Next, the bracket portion 44 of the adjustable clamp 40 can be slid upwardly along the clamp cut out 22 until the bracket makes contact with the bottom wall 82 of the magazine 80. After the bracket portion 44 of the clamp 40 is urged upwardly into firm contact with bottom wall 81 of the magazine 80, knob 41 can be tightened to retain bracket 44 in the ammunition round loading position. Then, as best seen in
Thereafter, as best seen in
The pistol magazine loading process can continue in the same manner as for second round 70b serially for each of a number of additional rounds until the magazine is completely loaded to its capacity. Utilizing embodiments of the loader, users may be able to load a fifteen round capacity magazine in about thirty seconds, for example, with no discomfort to the user's hands.
