Non-projectile cartridge for firearm

Abstract

A non-projectile cartridge apparatus has a cartridge casing having a receiver positioned therein. Further, the non-projectile cartridge has a simulated primer positioned at the bottom of the cartridge casing. Moreover, the non-projectile cartridge has a rim positioned around at least a portion of a circumference of the cartridge casing. The rim is gripped by an extractor of a firearm after a firing pin of the firearm strikes the simulated primer. Additionally, the non-projectile member has a connector. The non-projectile member is in a closed position within the cartridge casing during a connection between the connector and the receiver. Further, the non-projectile member is in an open position during a disconnection between the connector and the receiver. The disconnection occurs as a result of the firing pin striking the simulated primer.

DETAILED DESCRIPTION

(15) A non-projectile cartridge is provided for use with a semi-automatic firearm. The non-projectile cartridge simulates certain features of a live cartridge, without the features of the live cartridge that pose safety concerns. Rather than emitting a projectile (e.g., a bullet) from the case through a barrel of a firearm, the non-projectile cartridge has a non-projectile member that only moves a relatively short distance (e.g., approximately one and one half millimeters) with respect to the non-projectile cartridge. The non-projectile member simulates emission of a bullet, but does not actually leave the non-projectile cartridgeit only moves a relatively short distance; such movement activates the slide of the firearm. (The distance may vary based on different calibers of the non-projectile member.) As a result, the non-projectile cartridge may be used by a firearm user in a firearm to safely perform firearm handling practice in a realistic manner without the safety hazards posed by a live, projectile-emitting cartridge.

(16) In particular, the non-projectile cartridge may be configured to generate a substantially similar force (e.g., kick) to that to that of a live, projectile-emitting cartridge used in the same firearm. Rather than producing an internal chemical reaction that is present within a live, projectile-emitting cartridge, the non-projectile cartridge emits a similar amount of a force via tension being removed from one or more springs; as a result, the slide of the firearm recoils with a similar amount of force. Accordingly, the non-projectile cartridge allows the firearm user to develop a similar muscle memory to the feel of using a live, projectile-emitting cartridge.

(17) Furthermore, unlike shooting a firearm with SNAP-CAPs, the non-projectile cartridge is configured to activate the slide of the firearm so that the slide fully retracts upon emission of a last non-projectile cartridge from the magazine of a firearm, thereby providing a realistic feel for firearm handling practice. In contrast, using SNAP-CAPs within a firearm only leads to the slide returning to its unretracted position after no more SNAP-CAPs remain within the magazine.

(18) The non-projectile cartridge may be used in firearms that hold similar sized live, projectile emitting cartridge. For instance, the non-projectile cartridge may be configured to fit a nine millimeter pistolno specialized firearm needs to be fabricated for use with the non-projectile cartridge. Moreover, in its extended form, the length of the non-projectile cartridge may be the same, or substantially similar, length as the live, projectile-emitting cartridge. Given that the extractor of a firearm is configured to allow a user to eject a live, projectile-emitting cartridge (i.e., by manually sliding the slide) without being emitted through the barrel, the non-projectile cartridge may be ejected via the extractor.

(19) Also, the non-projectile cartridge is particularly suitable for rapid-fire firearm handling practice (e.g., via a semi-automatic firearm), especially when cycling through multiple magazines of non-projectile cartridges. Just as in a realistic live firearm scenario, the firearm user would experience the slide in the retracted position after the last non-projectile cartridge in a magazine has been ejected, and would have to reposition the slide back into place before a subsequent non-projectile cartridge could be activated from a subsequent magazine.

(20) Additionally, the non-projectile cartridge may be easily reset for re-use with the firearm. After being ejected, the non-projectile cartridge may be recompressed so that it may be reused in the firearm.

(21) FIGS. 1A-1C illustrate an example of a non-projectile cartridge configuration 100. In particular, FIG. 1A illustrates a perspective view of a disassembled non-projectile cartridge 100. At the top of the non-projectile cartridge configuration 100 is situated a non-projectile member 101, which is housed within a cartridge casing 102. FIG. 1B illustrates the non-projectile member 101 housed within the cartridge casing 102 in a closed position, which is the state of the non-projectile cartridge configuration 100 when situated in a magazine or in the chamber of the firearm, prior to being stricken by a firing pin of a firearm.

(22) Turning again to FIG. 1A, the non-projectile member 101, which is a simulated bullet that does not actually exit the barrel of a firearm, has a connector 103 that operably attaches to a receiver 106 that is operably attached to the cartridge casing 102. In essence, the non-projectile member 101 remains in the closed position, as illustrated in FIG. 1B, when the connector 103 is attached to the receiver 106. When the connector 103 is detached from the receiver 106, the non-projectile member 101 extends outwardly from the cartridge casing 102 (e.g., approximately one and one half millimeters), as illustrated in FIG. 1C.

(23) Turning to FIG. 1A, in one embodiment, an outer spring 107 surrounds the wall 108 of the non-projectile member 101. The top of the outer spring abuts the underside of a top edge 109 of the non-projectile member 101, and abuts a bottom edge 110 of the cartridge casing 102. In the closed position, as illustrated in FIG. 1B, the top of the outer spring 107 is compressed against the underside of the top edge 109, and the bottom of the outer spring 107 is compressed against the bottom edge 110. Accordingly, the outer spring 107 is configured to exert pressure (e.g., fifteen thousand to thirty thousand pounds per square inch (psi)) while the non-projectile cartridge configuration 100 is in the closed position for the non-projectile member 101 to be emitted from the cartridge casing 102 to be in the open position.

(24) To keep the non-projectile cartridge configuration 100 in the closed position, the connector 103 is operably connected to the receiver 106. For example, in one embodiment, the closed position is maintained by one or more balls 111 maintaining contact between the receiver 106 and the connector 103. The one or more balls 111 may apply pressure to one or more portions of a periphery of a plunger 104 positioned within the receiver 106, while also being positioned within corresponding connector indents 112 and receiver indents 113. In other words, the connector indents 112 and the receiver indents 113 are aligned and kept in place when the one or more balls 111 protrude through both the connector indents 112 and the receiver indents 113.

(25) Furthermore, the plunger 104 may have a bottom portion that acts as a simulated primer 105. Upon a firing pin of a firearm striking the simulated primer 105, which does not cause a chemical reaction, the plunger 104 moves upward to allow the one or more balls 111 to partially move into one or grooves 117 of the plunger 104, thereby releasing the one or more balls 111 from the connector indents 112 and the receiver indents 113. As a result, the connector 103 is disconnected from the receiver 106, and the non-projectile member 101 is permitted to at least partially exit the cartridge casing 102 to be in the open position illustrated in FIG. 1A. Alternatively, the connector 103 may move with respect to the receiver 106, but remain connected to the receiver 106.

(26) In one embodiment, in order to restrict the distance that the non-projectile member 101 may travel out of the cartridge casing 102, the non-projectile member 101 may have a lip 114 positioned at the bottom thereof, as illustrated in FIG. 1A. Furthermore, the cartridge casing 102 may have a window 115. Upon moving upward, the lip 114 catches the top edge of the window 115, thereby preventing the non-projectile member 101 from moving beyond a predetermined distance with respect to the cartridge casing 102.

(27) Additionally, an inner spring 116 may be utilized to help propel the plunger 104 upward to allow the balls 111 to move at least partially out of the receiver indents 113, and fully out of the connector indents 112. The inner spring 116 may be uncompressed in the closed position illustrated in FIG. 1B, and compressed in the open position illustrated in FIG. 1C.

(28) FIGS. 2A and 2B illustrate a side perspective view of the closed and open positions illustrated in FIGS. 1B and 1C, respectively. In particular, FIG. 2A illustrates the balls 111 positioned such that they apply friction to the plunger 104, thereby rendering the plunger 104 immobile. Furthermore, the balls 111 are positioned in both the connector indents 112 and the receiver indents 113. As a result, the connector 103 is effectively connected to the receiver 106 to lock the non-projectile member 101 in a fixed position within the cartridge casing 102.

(29) Upon impact between a firing pin of a firearm and the simulated primer 105, the balls 111 are able to move inwardly away from the connector indents 113, as illustrated in FIG. 2B. The balls 111 may still remain partially within the receiver indents 113, but the balls 111 move inward enough to move out of the connector indents 112. As a result, the tension in the major spring 107 is released, which allows upward pressure on the underside of the top edge 109 of the non-projectile member 101 to move the non-projectile member 101 outside of the cartridge casing 102.

(30) FIGS. 3A-3C illustrate an example of a firearm 300 (e.g., a pistol) using the non-projectile cartridge configuration 100 illustrated in FIGS. 1A-1C. In particular, FIG. 3A illustrates the non-projectile cartridge configuration 100 chambered within the firearm 300. A magazine 305 may hold multiple non-projectile cartridges 100. Further, FIG. 3B illustrates a firing pin 302 striking the simulated primer 105 after activation of a trigger 306, which leads to the non-projectile member 101 partially exiting the cartridge casing 102. Finally, FIG. 3C illustrates the non-projectile cartridge 100 being ejected from an ejection chamber 304 of the firearm 300 (e.g., by an extractor), without exiting a barrel 303.

(31) In an alternative embodiment, multiple indents may be used instead of the lip 114 and the window 115 illustrated in FIG. 1A. Accordingly, FIGS. 4A-4C illustrate an alternative non-projectile cartridge configuration 400. In particular, FIG. 4A illustrates a perspective view of a disassembled non-projectile cartridge 400. The connector 103 may have top connector indents 401a and bottom connector indents 401b. The balls 111 may be situated in the top connector indents 401a in the closed position, as illustrated in FIG. 4B. Upon the firing pin 302 striking the simulated primer 105, the plunger 106 may move until the bottom connector indents 401b reach the balls 111, which corresponds to the open position, as illustrated in FIG. 4C. Although the spring 107 is illustrated as being exposed in FIG. 4C in the open position, in an alternative embodiment, a covering (e.g., sleeve) may surround at least a portion of the spring 107.

(32) FIGS. 5A and 5B illustrate a side perspective view of the closed and open positions illustrated in FIGS. 4B and 4C, respectively. In particular, FIG. 5A illustrates the balls 111 positioned such that they apply friction to the plunger 104, thereby rendering the plunger 104 immobile. Furthermore, the balls 111 are positioned in both the top connector indents 401a and the receiver indents 113. As a result, the connector 103 is effectively connected to the receiver 106 to lock the non-projectile member 101 in a fixed position within the cartridge casing 102.

(33) Upon impact between a firing pin of a firearm and the simulated primer 105, the balls 111 are able to move inwardly away from the top connector indents 401a, as illustrated in FIG. 5B. The balls 111 may still remain partially within the receiver indents 113, but the balls 111 move inward enough to move out of the top connector indents 401a. As a result, the tension in the major spring 107 is released, which allows upward pressure on the underside of the top edge 109 of the non-projectile member 101 to move the non-projectile member 101 outside of the cartridge casing 102. The non-projectile member 101 stops movement when the balls 111 fall into the bottom connector indents 401b.

Other types of ejection mechanisms (e.g., compressed air device) may be used instead. Furthermore, the balls described herein, and illustrated in the drawings, are only examples of locking/capturing mechanisms.
