BACKGROUND AND FIELD
1. Field
The present device relates to an original reloadable, non-detachable box magazine for carbine type rifles that are similar to commercially available detachable magazines yet sufficiently improved in that it is non-removable while being reloadable, preferably with no more than ten rounds of ammunition preloaded on a commercially available stripper clip.
2. Background
In the past magazines for carbine type rifles were detachable from the rifle receiver by pressing a button or using a tool to depress an interior magazine release catch, such that the magazine would drop away from the rifle's receiver or could be physically removed. Such systems are well known in the art. Legislation in some U.S. states prohibits the use of detachable magazines with some weapon types. The detachable magazines prohibited in California, for example, include any ammunition feeding device that can be removed readily from a firearm with neither disassembly of the firearm action or use of a tool.
Attempts have been made to provide locking mechanisms to prevent detachment of a magazine. Such “magazine locks” suffer from disadvantages, however. For example, magazine locks with an upwardly-oriented locking pin may require a tool to depress the pin, allowing insertion of the magazine into the rifle. Further, such an upward orientation may interfere with the functioning of the follower. Because the index slot for the magazine lock in a conventional metal AR-15, for example, is flat in comparison to the body of the magazine, the magazine lock my be forced to extend further into the magazine to engage the locking pin, which may wear on the inside of the receiver. Finally, existing locking mechanisms may require opening of a weapon's action for reloading, which may wear out pins and pinholes between the receiver and the rest of the weapon.
SUMMARY
The present device provides a non-detachable box magazine for carbine type rifles to comply with state laws that ban detachable magazines. One embodiment of the present device provides a reloadable, non-detachable system for use in current commercially available carbine rifles using a preloaded, ten-round, commercially available stripper clip of ammunition.
Once the present magazine is inserted into a carbine rifle it cannot be removed without the opening the rifle's ‘action’ and using a tool to pull up on a securing detent located at the bottom of the magazine locking device, allowing the user to press the magazine release button located on the side of the receiver of the carbine rifle and removing the magazine. This is a cumbersome process designed to prevent rapid removal of the device and comply with state law.
In one broad aspect, the present device may be considered a non-detachable, reloadable box magazine system having a magazine body of two sides, opposing end walls, an open top with curved feed lips, an open bottom with base plate stop tabs, base plate arched receiver pocket, stripper clip stop tabs, squeeze tab receiver lock detents, magazine and upper magazine index slot and stop tab.
The system is further comprised of a non-removable but detachable base plate, rear magazine wall cover, base plate stop tabs, squeeze tab release, base plate arched receiver guide, capacity limiting block, spring, base spring retention tab, follower, follower guide tabs, follower spring retention tab, follower leveling guides, and follower spring torque limiter.
Additional system components include a magazine locking device with threaded rod, span arm, magazine retention tab, and locking detent.
The various embodiments described herein operate generally as follows, with greater detail regarding the operation provided below. When a user squeezes the squeeze tabs located on each side of the base plate, the base plate locking tab disengages from the opposing squeeze tab receiver lock detent. This allows the user to pull the base plate in a downward motion. The base plate arched guide attached to the base plate is indexed by the magazine body base plate arched receiver pocket, which keeps the base assembly aligned in the proper curved orientation. This process pulls the spring, follower, capacity limiting block, base plate arched guide, and magazine rear wall cover downward while keeping all components aligned to the curve of the magazine body and exposing the inner chamber of the magazine. The capacity limiting block in conjunction with the base plate arched guide and the follower guide tabs act to keep the spring and follower oriented in the same arched manner until the base of the follower and base plate arched guide contact the base plate stops located on the inside of the magazine body walls and the top of the base plate arched guide.
This process reveals the inner chamber of the magazine body. At this point the user inserts one preloaded ten-round ammunition stripper clip into the open magazine inner chamber until it meets the stripper clip stop tabs located inside the magazine body wall.
The user then reverses the process and closes the magazine base plate, follower, spring, base plate arched guide, capacity limiting block, and rear magazine wall cover until the base plate squeeze tabs re-engage the opposing magazine body lock detents, completing the process of closing the magazine. In this process, the follower makes contact with the bottom shell casing of ammunition held in place by the stripper clip, causing the follower and spring to compress until enough pressure is applied to cause the rounds to release through the top tab of the stripper clip where they are then pushed upward into the upper part of the magazine body. The rounds are held in index by the shell casing guide slot, shell casing guide tabs, follower guide/shell case nose guide rails, and the follower until they are forced up and against the feed lip located at the top of the open magazine body.
One aspect of the present disclosure provides an improvement to a rifle having a lower receiver defining a magazine chamber. The improvement includes a magazine body attached to the rifle, and a base plate releasably and slidingly engaging the magazine body and forming a base of the magazine body. A release is provided to unlock the base plate when actuated by a user of the rifle. The base plate is configured to move away from the magazine body when unlocked, thereby exposing an inner chamber of the magazine body for insertion of an ammunition stripper clip thereinto.
Another aspect of the present disclosure provides an improved rifle further having a locking member removably attached to the magazine body. The locking member includes a threaded rod configured for insertion through an opening defined in the lower receiver of the rifle and an arm extending from the threaded rod at about a ninety degree angle thereto. A detent member extends downwardly from the arm. The detent member is configured to be received into a slot defined in the magazine body, and when the detent member is received into the magazine body the magazine body is securely affixed to the rifle.
Another aspect of the present disclosure provides an improved rifle in which the threaded rod is configured to be inserted into an opening sized and shaped to receive a conventional magazine release assembly.
Another aspect of the present disclosure provides an improved rifle in which a tab extends from the base plate. The tab is configured to be received into a slot defined in the magazine body.
Another aspect of the present disclosure provides an improved rifle having an arched guide extending upwardly from the base plate and an arched receiver pocket defined in the magazine body and configured to slidingly receive the arched guide. A first stop tab extends from the arched receiver pocket. A second arched tab extends from the arched guide. When the base plate is moved slidingly in a downward direction, away from the magazine body, contact between the first stop tab and the second stop tab prevents the base plate from being detached from the magazine body.
Another aspect of the present disclosure provides an improved rifle having a rear wall cover plate extending upwardly from the base plate. The magazine body is configured to slidingly receive the rear wall cover plate. When the base plate is locked to the magazine body, the rear wall cover plate cover the inner chamber of the magazine body. When the base plate is disengaged from the magazine body, the downward movement of the base plate, and corresponding downward movement of the rear wall cover plate, exposes the inner chamber of the magazine.
Another aspect of the present disclosure provides an improved rifle having a lower receiver defining a magazine chamber. The improved rifle includes a magazine body attached to the rifle. A locking member is included, having a threaded rod configured to be received through the lower receiver of the rifle. The locking member also has an arm extending away from the threaded rod and a detent member extending away from the arm in other than an upward direction. A base plate is slidingly engaged with the magazine body and movable between a first position and a second position. When the base plate is in the second position, an opening is defined in the magazine body, thereby exposing an inner chamber of the magazine body. The opening is sized and shaped to receive an ammunition stripper clip. When the detent member is received into a slot defined in the magazine body, the magazine body cannot be removed from the rifle.
In another aspect of the present disclosure, when the detent member and slot are mated they are accessible only by opening the action of the rifle.
Another aspect of the present disclosure provides a box magazine having a magazine body including a slot defined therein. The slot is configured to receive a detent member from a locking member associated with the lower receiver of a rifle. A base plate is slidingly engaged with the magazine body and moveable between a first position and a second position. When the base plate is in the second position, and opening is defined in the magazine body, exposing an inner chamber of the magazine body. The opening is sized and shaped to receive an ammunition stripper clip.
In another aspect of the present disclosure, the slot defined in the box magazine is in such a position as to receive the detent member only if the detent member extends other than in an upward direction from the locking member.
In another aspect of the present disclosure, an upper end of the box magazine is configured to be received into a conventional magazine chamber of a lower receiver of a rifle.
In another aspect of the present disclosure, the box magazine includes an arched guide extending upwardly from the base plate and an arched receiver pocket defined in the magazine body and configured to slidingly receive the arched guide. A first stop tab extends from the arched receiver pocket. A second arched tab extends from the arched guide. When the base plate is moved slidingly in a downward direction, away from the magazine body, contact between the first stop tab and the second stop tab prevents the base plate from being detached from the magazine body.
Another aspect of the present disclosure provides a locking magazine catch assembly having a span arm, a threaded rod extending from the span arm, a biasing member attached to the span arm, and a detent member engaging the biasing member such that the biasing member reversibly biases the detent member away from the span arm in other than an upward direction. The biasing member may be a spring or any other suitable biasing member. The detent member is configured to be received into an opening defined by the magazine body.
In another aspect of the present disclosure, the threaded rod is configured for insertion through an opening defined in a lower receiver of a rifle.

Specifically squeeze tab locks 37 and 39 and their matching squeeze tab receiver detents 87 (and hidden 86 referred above in FIGS. 11A and 11B). Further illustrations detail spring 48 retention tab 46, follower guide/shell casing neck retainer rails 76 and 78, follower stop tabs 65 and 67, and capacity limiting block 35, including how it provides center support to spring 48.
FIG. 13 illustrates the open magazine, as a cut away, skewed plan view, illustrating a stripper clip assembly 116 inserted into the magazine system chamber, as well as the manner in which stripper clip 116 components 122 and 124 (identified in FIG. 14) match internal magazine components 82 and 84 (not shown), how stripper clip 116 rests against stripper clip stop rails 64 and 66, and the method of indexing provided by follower guide/shell case neck retainer rails 76 and 78.
FIG. 14 illustrates a commercially-available preloaded stripper clip 116 containing ten rounds of ammunition. Stripper clip 116 includes brass spring device 118, end tab 120, retainer rails 122 and 124, and shell casings 126.
FIG. 15 illustrates the locking device, depicting threaded rod 90, spanner arm 92, tab 94 lock detent 96 and cover plate 114. FIGS. 16A and 16B show alternative view of the locking device assembly of FIG. 15. The locking device includes a threaded rod 90, span arm 92, tab 94, detent pin 96, sloped face 100, tension spring 98, inter locking tabs 102, 104, 106 and 108, compression studs 110 and 112, and cover plate 114.
FIGS. 17A and 17B illustrate the locking device inner components, such as detent pin 96, tension spring 98, sloped face 100, interlocking tabs 102 and 104, corresponding tab receiver slots 106 and 108, and compression studs 110 and 112.
FIGS. 18, 19, and 20 illustrate the upper magazine index slot, stop tab 26, detent slot 25 as it relates to the locking device function, tab 94, detent pin 96, slope face 100, and spanner arm 92, securing the non-detachable/reloadable magazine system to the carbine type rifle.
One embodiment of a non-detachable reloadable box magazine device requires a locking device to be installed on the carbine type rifle. FIGS. 15, 16A, 16B, 17A, and 17B, described above, depict various features of one embodiment of such a locking device. Designed similarly to a non-locking commercially available magazine release assembly, this improved design, once installed, does not allow the box magazine system device to be removed without significant effort requiring the opening of the rifle's action and the use of a tool to pull up on the locking detent.
The locking device prevents removal of the magazine system by utilizing a detent pin 96, sloped face 100, interlocking tabs 102 and 104, corresponding to tab receiver slots 106 and 108 respectively and locking tab spring 98 all secured behind a cover plate 114, attached to tab 94 by compression studs 110 and 112 through matching holes in cover plate 114.
As indicated above, FIGS. 18, 19, and 20 illustrate the components of magazine wall 14 with upper magazine index slot 24, detent slot 25, stop tab 26, and how they relate to the components of the locking device. As the magazine is inserted into the rifle's magazine well, stop tab 26 forces detent pin 96 up into tab 94. The locking device then slams into upper magazine slot 24 and detent pin 96 drops into detent slot 25, effectively locking the non-detachable reloadable magazine system securely to the carbine type rifle.
Once installed on the rifle using an additional commercially available spring and push button nut, it prevents the removal of this non-detachable reloadable magazine device.
One alternative embodiment of the present disclosure is now described.

FIGS. 31A and 31B illustrate an open bottom 221 view of the internal components of magazine walls 214 and 220 with an illustration of the top of base plate arched guide 240 and the arched guide stop tabs 245 and 247. Arched guide stop tabs 245 and 247 prevent the base plate arched guide from exiting from base plate arched receiver pocket 270, prevented from doing so by the corresponding stop tabs 273 and 275 located at the base of base plate arched receiver pocket 270. The figures also illustrates the follower stop tabs 261, 265, and 267. The tabs prevent the follower 252 from exiting out of the open base 221 when the base magazine system is in the fully open position. An additional component of base plate arched guide 240 is the travel limiter tab 249, which retains follower 252 and spring 248 relative to base plate arched guide 240 when the system is pulled in the open configuration. Without this travel limiter tab 249, follower 252 and spring 248 would naturally revert to the springs fully extended point. This would conflict and hamper the insertion of the stripper clip assembly 316.
FIGS. 31A and 31B further detail the squeeze tab receiver lock detent 286 unseen when the magazine system is assembled, as well as the follower stop tabs 261, 265, and 267 that prevent follower 252 from exiting the open bottom 221 during the process of reloading.
FIG. 32 illustrates the components of base plate assembly 228 and how they relate to corresponding components inside open bottom 221. Specifically squeeze tab lock 238 and their matching squeeze tab receiver detents 286. Further illustrations detail spring 248 retention tab 246, follower guide/shell casing neck retainer rails 276 and 278, follower stop tabs 261, 265, and 267, and capacity limiting block 235, and how it provides center support to spring 248.

This embodiment of a non-detachable reloadable box magazine device requires a locking device to be installed on the carbine type rifle. As noted above, FIGS. 35, 36A, 36B, 37A, and 37B depict an embodiment of such a locking device. Designed similarly to a non-locking commercially available magazine release assembly, this improved design, once installed, does not allow the box magazine system to be removed without significant effort requiring the opening of the rifles action and the use of a tool to pull up on the locking detent.
The locking device prevents removal of the magazine system by utilizing a detent pin 296, sloped face 300, interlocking tabs 302 and 304, corresponding to tab receiver slots 306 and 308 respectively, and locking tab spring 298, all secured behind a cover plate 314, attached to tab 294 by compression studs 310 and 312 through matching holes in cover plate 314.
FIG. 38 illustrates the components of magazine wall 214 with upper magazine index slot 224, detent slot 225, stop tab 226 and how they relate to the components of the locking device 292. As the magazine is inserted into the rifle's magazine well, stop tab 226 forces detent pin 296 up into tab 294. The locking device 292 then slams into upper magazine slot 224 and detent pin 296 drops into detent slot 225 effectively locking the non-detachable reloadable magazine system securely to the carbine type rifle.
Once installed on the rifle using additional commercially available spring and push button nut it prevents the removal of this non-detachable reloadable magazine invention.

Stop tabs 651 and 653 prevent the arched base plate guide from exiting from arched base plate receiver pocket 670, prevented from doing so by the corresponding arch guide stop tabs 673 and 675 located at the base of arched base plate receiver pocket 670 below the assembly key slots 669 and 671 (FIG. 69). These stop tabs are a reduction in the slot size of retainer tab tracks 672 and 674 and created the necessity for the addition of the assembly key slots 669 and 671. An additional component of base plate arched guide 640 is the travel limiter tab 649 which retains follower 652 and spring 648 (not shown) relative to arched base plate guide 640 when the system is pulled in the open configuration. Without this travel limiter tab 649, follower 652 and spring 648 would naturally revert to the springs fully extended point. This would conflict and hamper the insertion of the stripper clip.

FIG. 74 illustrates a commercially available preloaded stripper clip 716 containing ten rounds of ammunition. Stripper clip 716, brass spring device 718, end tab 720, retainer rails 722 and 724, shell casings referred generally as 726.
FIGS. 75, 76, and 77 illustrate the upper magazine index slot 624, stop tab 626, detent slot 625 as it relates to the locking device function, tab 694, detent pin 696, slope face 700 and spanner arm 692, securing the non-detachable/reloadable magazine system to the carbine type rifle.
As the magazine is inserted into the rifle's magazine well, stop tab 626 forces detent pin 696 up into tab 694. The locking device 692 then slams into upper magazine slot 624 and detent pin 696 drops into detent slot 625 effectively locking the non-detachable reloadable magazine system securely to the carbine type rifle. Once installed on the rifle using additional commercially available spring and push button nut it prevents the removal of this non-detachable reloadable magazine invention.
FIGS. 78, 79, 80, and 81 illustrate the components involved in the rear wall extension rails. FIG. 78 is the open bottom end view of the magazine body indicated generally as 610. FIGS. 79 and 80 depicts the rear wall extension rail(s) 645 and 647, 647 is a mirror image of 645. FIG. 81 is of the rear magazine wall cover 634 which is integrated into the base 628. FIG. 82 is an end view of the rear wall extension rail.
Rear wall extension rails 645 and 647 are inserted into the rear magazine extension rail guide slots 629 and 631 respectively. Once inserted the extension rail stop tabs 681 located at each end of the rear magazine extension rail are prevented from removal by extension rail stop tabs 677 and 679 located in the base of rear magazine extension rail guide slots 629 and 631. The rear wall extension rails 645 and 647 are then inserted into the rear wall extension rail guide slots 657 and 659 respectively. The extension rail stop tabs 681 then interact with the extension rail stop tabs 685 and 689 locate at the top end of rear wall extension rail guide slots 657 and 659 respectively. Once assembled the components provide additional strength to the magazine operation when in the open position for loading. Further indexing is achieved for the insertion of a stripper clip assembly 716. This assembly adds additional restriction to the errant movement of the spring 648 and the follower assembly 652 during the reloading process. Back wall block 633 adds rigidity to the entire assembly during the reloading process.
General operation of the various embodiments of the present disclosure is now provided in detail.
The base plate and squeeze tabs of the device are depressed until the squeeze tab lock is freed from the squeeze tab receiver lock detents. The grip tab and squeeze tab are used to draw the base plate downward. The base plate arched guide, which is retained in the base plate arched receiver pocket by correlated indexing between the arch guide tabs, and the retainer tab tracks keep the system components aligned.
The base plate arched guide and corresponding base plate arched receiver pocket preferably run the entire length of the magazine body interior wall. This indexing allows the base to move up and down in a smooth sweep motion. The following components are preferably permanently affixed to the base plate: the squeeze tabs, including the lock tab, the grip tab, the base plate arched guide, the side magazine wall cover, the side wall cover guide rail, the spring retention tab, and the capacity limiting block. While these are preferably permanently affixed, it is contemplated that any or all of these components may be removably attached to the base plate. The base plate assembly is preferably affixed to the spring by the spring retention tab, which in turn retains the follower assembly at the other end of the spring by another spring retention tab. The travel limiter tab interlocks with the follower in the travel limiter slot and together retains all components at a desired overall length while keeping all internal components of the system together as one movable unit.
As the downward pull of the base plate continues, the travel limiter tab pulls the spring and follower down with it. The follower is held in index in a number of ways. The follower tab receiver slots rise along the follower guide/shell case nose guide rails. In addition, the follower end guides and the spring torque limiter ride along the inside walls of the box magazine, keeping the follower horizontally indexed. As the base plate completes its downward motion, the follower stop tabs at the base of the magazine body, in conjunction with the arched guide stop tabs at the top of the base plate arched guide, prevent the base plate assembly from existing out of the open bottom when fully open. The follower guide/shell case neck retainer rails preferably run the full inside length of the magazine walls, from top to bottom, while following the general curve of the magazine shape, and are oriented to corresponding with the shell casing neck, just forward of the shell casing bevel. The rails provide secondary support of the shell case by preventing side to side horizontal movement of the case neck. The rails also provide a guide track for the follower through the interaction of the rails and the tab receive slots located on the follower.
An ammunition stripper clip assembly can now be loaded into the weapon, as described into greater detail below. The user then reverses the process described above.
Upward force applied to the bottom of the base assembly, which is guided by the correlation with the base plate arched guide, retained in the base plate arched receiver pocket, causes the follower to contact the shell casing of the first (bottom) round of ammunition. This compresses the spring and follower until the bottom of the follower contacts the top of the capacity limiting block. During this phase of compression, the spring is held from deformation by the capacity-limiting block, spring torque limiter, and base plate arched guide.
As additional force is applied to the base plate assembly, the tab on the top of the stripper clip assembly bends upwards into the shell casing base guide slot, allowing the continuously-applied force to push rounds up and away from the stripper clip assembly and into the shell casing base guide slot. The bases of the rounds are held in index by the shell casing base index tabs as they pass up and into the shell casing base guide slot. The rounds are held in index by an additional combination of interior components, which include the follower guide/shell case neck retainer rails and the box magazine side wall, until the top round of ammunition contacts the box magazine feed lip and is retained in the proper orientation by the shell case index block. Further upward force now compresses the follower and spring until the base plate squeeze tab lock re-engages with the box magazine squeeze tab receiver lock detent, and the side wall cover guide rail engages the side wall index tab, completing the cycle securely closing the magazine system.
Further details of the loading process are now described.
A preferred embodiment of the non-detachable/reloadable magazine device of the present disclosure relies on a commercially-availabile preloaded stripper clip containing ten rounds of ammunition. This eliminates the burden of loose rounds (or shell casings). Once the stripper clip assembly is inserted, force applied by the compression of the follower, the spring, and the capacity limiting block, mates the base of the stripper clip assembly with the internal components of the box magazine. The shell casing base guide slot and the shell casing base index tabs are designed to marry in a transfer between the base of the stripper clip and the shell casing guide slot. The stripper clip shell casing retainer rails correspond to the shell casing base index tabs. These components lock the shell casings from twisting, sliding, or elevating out of the established index created by the stripper clip design. The internal magazine components provide the necessary transitional channel allowing the shell casing to be forced up without losing continuity or becoming loose within the magazine chamber. The base support system, in conjunction with the follower guide/shell casing neck retainer rails, further prevent induced malfunction of the loading transfer process of the preloaded stripper clip assembly. The box magazine shell case index block, and curved feed lip, prevent the first, or top, round of ammunition from miss aligning thereby completing the process.
In preferred embodiments of the present disclosure, the magazine box is about 7½ inches long and about ⅞ of an inch wide, with a width of about 2⅝ inches, an interior length of 7½ inches, width of 2⅜ inches, and depth of about ¾ of an inch. Also in such preferred embodiments, the top portion of the magazine body is straight for about 2.5 inches then arched in the lower 5 inches or so at a radius of about 11 inches with an angle of about 21 degree angle. It is contemplated, however, that any suitable dimensions may be employed with respect to the device of the present disclosure, or any of its parts, and that the dimensions provided above are not limiting.
It is to be understood that the various embodiments described herein are exemplary, and that modifications to what is disclosed herein may be readily apparent to those of skill in the art upon reading this disclosure. Such modifications are contemplated to be within the spirit and scope of the present disclosure.
