Abstract
An unloader (10) for firearm magazines (40) has a plate hingedly coupled to a back of the magazine so the plate can be moved against or tilted away from the magazine. The plate has a projecting plunger at its top that can push a round out of the top of the magazine when the plate is moved against the magazine's back. The plate is hingedly coupled to the magazine by holding it with a thumb or finger or by hinging it to an adapter that is coupled to the magazine. A user holds the adapter or the plate against the magazine and moves the plate between open and closed positions. In the closed position the plunger forces the top round forward and out from the lips of the magazine and in the open position the plunger allows the magazine's follower to push a second round into the top position.

OperationFIGS. 1A-2C
(26) The unloader provides substantial assistance to a firearm user by enabling the user to safely, comfortably, and very rapidly unload magazines without finger pain or injury. Principally, unloading rounds from a magazine is accomplished by repeatedly operating the unloader (moving its pusher from it open position to its closed position) to sequentially push forward the top round of the magazine far enough to clear it from the holding lips.
(27) To install the unloader (comprising the hinged adapter and pusher plates) on the magazine, side walls 14 of the adapter are slid over the lateral sides of the magazine as shown in
(28) The rounds in a loaded magazine can be quickly unloaded by fitting and holding the unloader onto the back side of the magazine with one hand, preferably pressing adapter body 12 with the thumb, and holding the other side of the magazine with the fingers as illustrated in
(29) By altering the design and dimensions of the unloader's parts under the principles and methods described, a range of unloaders can be constructed to unload a variety of magazines and round calibers.

(31) In this embodiment, unloader 50 is positioned at the top rear wall of magazine 70 with the inwardly inclined side-walls portions 56 positioned resting on the rear top of the magazine's lips 72 (
(32) As shown, the same basic construction and method of operation of unloader 50 remain as explained further above. Those skilled in the art can easily design and construct alternative unloaders to fit other magazine types.

Third Alternative UnloaderDescription and OperationFIGS. 4A-4CPerspective Views
(34)
(35) Note that, as with the other embodiments, back plate 100 has a body portion having a bottom end (including magazine recess 19), a top end, and a pair of opposite side edges extending between the bottom and top ends. The bottom end is pivotable with respect to the back wall of magazine 40 so that the body portion of the plate can be tilted or pivoted with respect to the back wall, against or away from the back wall. Its top end 106 can be manually grasped by a user. The plate has a pair of side walls 102 which extend perpendicularly from the opposite side edges of the body portion. The side walls are spaced to sandwich and extend only partially over the lateral sides of the magazine, so that when the plate is pivoted away from the back wall (
(36)
(37) Using the right or other hand, the user initially tilts the top of unloader away to the open position from the magazine as shown in
(38) The user's right hand now tilts the unloader back and forth. If the thumb or finger of the user's left hand holds the loader in the correct position, its hole 108 will receive the magazine's catch pin 18P and plunger 104 will contact the rear of the rounds and expel them. When the unloader is pivoted against the magazine, if the loader isn't in the correct position, hole 108 will not receive the pin and the plunger will not contact the top round or expel it. In this case the user will be able to adjust their thumb or fingerand hence the unloader's positioneasily so that hole 108 will receive the pin and the plunger will contact and expel rounds after one or two tries. The loader is effectively hinged or made pivotable on the magazine through the use of its bottom edge as a pivot and thumb or finger force to hold the loader in place. Sidewalls 102 stabilize and center the unloader's horizontal position during operation.
(39) This unloader is less stable and requires more concentration and skill to operate than the previous two-part versions, yet can unload rounds equally well. Again, those skilled in the art can easily modify the design and construct alternative unloaders to fit other magazine types.
CONCLUSION, RAMIFICATIONS, AND SCOPE
(40) The reader will see that we have provided an efficient, simple, low-cost, palm-size, comfortable and safe magazine unloader comprising few parts. The unloader and variants thereof can unload a wide range of magazines by pushing the top round forward with a plunger extending from a mechanically hinged pusher or thumb- (or finger-) hinged pusher. The unloader allows painless, comfortable, and very quick unloading of rounds.
(41) While the above description contains many specificities, these should not be construed as limitation on the scope but rather as an exemplification of several embodiments thereof.
(42) All numerical values provided are approximate; they can be varied to adapt to other magazines or round types and or sizes. The following are further examples of some but not all variations and ramifications:
(43) The unloader can be adapted to fit and operate with most pistol and rifle magazines and calibers available in the market by providing suitable changes in construction and dimensions under the principles described above. While magazines with followers that are pushed upward by springs have been discussed, the unloader can as well be used to unload magazines with followers that are pushed up by spring-driven rotatable drums.
(44) The unloader and its components may be made of various polymer or other plastic materials, or, alternatively, of other materials, as aluminum, steel or wood, or any combination thereof.
(45) Various other hinging mechanisms and methods may replace the hinging mentioned above. For example, hinging between the adapter body and pusher can be done with a male-female interlocking hinge, a male-female hinge with a coupling pin, and hinging using flexible parts such as rubber or silicon. Hinging can be on the opposite (rear) side of the unloader/plunger.
(46) Various other stopper mechanisms and methods may replace the stopper mentioned above. For example, a semi-circular hinge projection and matching hinge hole designed to limit relative movement can be easily designed and constructed.
(47) The maximum open angle between the adapter body and the pusher may be altered to adapt to other magazines and rounds.
(48) The unloader may also be constructed to include or accept insertable spacer(s) positioned at the inner part of the adapter body opening to accommodate magazines of different widths and/or overall rear-side construction and dimensions.
(49) The unloader's plunger may also be constructed to include or accept insertable spacer(s) or adjusters to change its length or construction to accommodate magazines of different depths and lip construction and/or adapt to rounds of different calibers and lengths.
(50) The adapter body of the unloader may be altered to be removably fixable or lockable to the upper top side of the magazine so the user will not have to hold the adapter body in place when unloadingworkable under the method and descriptions here described.
(51) A lock mechanism may be included in the unloader to lock and keep the adapter body and pusher closed so to minimize the size of the unloader for transport and storage.
(52) The unloader plunger may be made foldable, hinged, or removable so to reduce size further.
(53) Accordingly, the scope of our loader should be determined not by the embodiments illustrated, but by the appended claims and their legal equivalents.
