The disclosure relates to automatic magazine devices and more particularly pertains to a new automatic magazine device for automatically ejecting an ammunition magazine from a firearm. The device includes an ammunition magazine and a door hingedly coupled to the ammunition magazine which has a recess integrated into the door. The door is biased into an engaging position to facilitate a magazine release in a firearm to engage the recess for retaining the ammunition magazine in the firearm. The device includes a magnet integrated into a follower of the magazine which urges the door into a disengaging position when the last round of ammunition is fed into the firearm thereby facilitating the ammunition magazine to drop out of the firearm.
The prior art relates to automatic magazine devices including a variety of automatically ejecting ammunition magazine devices which each includes some manner of ejection mechanism that involves active mechanical communication between a follower and an ejection device for automatically ejecting the ammunition magazine from a firearm when the last round of ammunition is fed into the firearm. In no instance does the prior art disclose an automatically ejecting ammunition magazine that employs a magnet for remotely actuating an ejection device to automatically eject the ammunition magazine from the firearm when the last round of ammunition is fed into the firearm.
An embodiment of the disclosure meets the needs presented above by generally comprising an ammunition magazine which is substantially hollow for receiving ammunition for a firearm. A follower is movably disposed within the ammunition magazine to support ammunition for the firearm and a magnet is attached to the follower. A door is hingedly attached to the ammunition magazine and the door has a recess which is engaged by a magazine release of the firearm to retain the ammunition magazine in the firearm. The magnet urges the door into a disengaged position such that the recess is not accessible to the magazine release. In this way the ammunition magazine can drop out of the firearm when the last round of ammunition is fed into the firearm.
There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
The outer wall 20 has a hole 38 extending into the interior of the ammunition magazine 12. The hole 38 extends from the lip 34 associated with the first lateral side 28 toward the bottom wall 18 and the hole 38 is positioned closer to the back side 30 than the front side 32. A follower 40 is movably disposed within the ammunition magazine 12 thereby facilitating the follower 40 to support ammunition 14 for the firearm 16. The follower 40 has a top surface 42 and the top surface 42 has a depression 44 extending between a front end 46 and a back end 48 of the follower 40. The depression 44 is concavely arcuate thereby facilitating the depression 44 to conform to curvature of the ammunition 14 for the firearm 16.
A magnet 50 is provided and the magnet 50 is attached to the follower 40. The magnet 50 is integrated into a lateral surface 52 of the follower 40 such that the magnet 50 is directed toward a first lateral side 54 of the outer wall 20 of the ammunition magazine 12. Additionally, the magnet 50 is positioned closer to the back end 48 of the follower 40 than the front end 46 of the follower 40. A biasing member 56 is positioned between the bottom wall 18 of the ammunition magazine 12 and a bottom surface 58 of the follower 40 such that the biasing member 56 biases the follower 40 to travel upwardly in the ammunition magazine 12. As is most clearly shown in
A door 60 is hingedly attached to the ammunition magazine 12 and the door 60 has a recess 62 integrated into the door 60. The recess 62 can be engaged by a magazine release 64 of the firearm 16 when the ammunition magazine 12 is inserted into the firearm 16 for releasably retaining the ammunition magazine 12 in the firearm 16. The door 60 is biased into an engaged position having the door 60 lying flush with the ammunition magazine 12 such that the recess 62 is accessible to the magazine release 64 thereby facilitating the ammunition magazine 12 to be retained in the firearm 16. The magnet 50 urges the door 60 into a disengaged position having the door 60 angling inwardly into the ammunition magazine 12. Thus, the recess 62 is not accessible to the magazine release 64 thereby facilitating the ammunition magazine 12 to drop out of the firearm 16 when the last round of ammunition 14 is fed into the firearm 16.
The door 60 has a lower edge 66, an upper edge 68 and an outwardly facing surface 70 extending between the upper edge 68 and the lower edge 66. The door 60 is curved adjacent to the upper edge 68 such that the upper edge 68 is aligned with the lip 34 associated with the first lateral side 26 of the top edge 22 of the outer wall 20 of the ammunition magazine 12 when the door 60 is in the engaged position. The outwardly facing surface 70 is oriented flush with the first lateral side 26 of the outer wall 20 of the ammunition magazine 12 when the door 60 is in the engaged position. Conversely, the outwardly facing surface 70 is spaced inwardly from the first lateral side 26 of the outer wall 20 having the upper edge 68 being spaced inwardly from the lip 34 associated with the first lateral side 26 of the top edge 22 of the outer wall 20 when the door 60 is in the disengaged position. The magnet 50 on the follower 40 is aligned with the door 60 when the follower 40 is biased into a topmost position when the last round of ammunition 14 is fed into the firearm 16.
A hinge 72 is included which has a first portion 74 that hingedly engages a second portion 76. The first portion 74 is attached to the outwardly facing surface 70 of the door 60 and the second portion 76 is attached to the first lateral side 26 of the outer wall 20 of the ammunition magazine 12. The hinge 72 is biased into an open position having the first portion 74 being oriented coplanar with the second portion 76. The hinge 72 is urgeable into a closed position having the first portion 74 being oriented at an angle with the second portion 76.
In use, the ammunition magazine 12 is loaded with ammunition 14 and the ammunition magazine 12 is inserted into the firearm 16. The magazine release 64 in the firearm 16 engages the recess 62 in the door 60 to retain the ammunition magazine 12 in the firearm 16. The magnet 50 in the follower 40 is aligned with the door 60 once the last round of ammunition 14 is fed into the firearm 16. In this way the strength of the magnetic attraction of the magnet 50 overcomes the biasing strength of the hinge 72 to urge the door 60 into the disengaged position. Thus, the recess 62 is disengaged from the magazine release 64 and the ammunition magazine 12 falls from the firearm 16. In this way the empty ammunition magazine 12 is automatically ejected from the firearm 16 to facilitate a loaded ammunition magazine 12 to be inserted into the firearm 16. Furthermore, the magnet 50 facilitates the door 60 to be urged into the disengaging position without requiring mechanical communication between the follower 40 and the door 60 thereby reducing the likelihood of a mechanical failure that would prevent the ammunition magazine 12 from automatically ejecting from the firearm 16.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, device and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
