Description

TECHNICAL FIELD

This disclosure relates to firearm safety assemblies and, more particularly to magazine safety assemblies for use within firearms.

BACKGROUND

Firearms often employ various safety devices to prevent the inadvertent and unexpected discharge of the firearm. For example, firearms typically employ passive trigger safeties that prevent the firearm from discharging due to inertia on the trigger in the event that e.g., the firearm is dropped. Additionally, more active safeties (e.g., thumb safeties) may be utilized that require the user to disengage the safety prior to discharging the weapon.

As is known in the art, some firearms utilize detachable magazines, wherein the magazine may be removed while a round is chambered within the firearm. Accordingly and on such a firearm, the firearm may be discharged without a magazine being loaded within the firearm. While some users (especially tactical and military users) prefer allowing the firearm to be discharged while the magazine is removed from the firearm, some jurisdictions (such as California) and some users prefer to prohibit the discharge of the firearm when the magazine is removed from the firearm. Accordingly, magazine safety assemblies may be utilized to prohibit the firearm from discharging when the magazine is removed from the firearm. Unfortunately, such magazine safeties typically decouple the trigger assembly from the firing system within the firearm. Accordingly, such systems may allow the displacement of the trigger assembly (in a manner similar to when the firearm is fireable) when the magazine safety assembly is engaged and would actually prohibit the firearm from discharging.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 1-3, there is shown firearm 10. Examples of firearm 10 may include but are not limited to a semiautomatic handgun. However, the subject disclosure may be applicable to any firearm having a detachable ammunition magazine assembly.

Firearm 10 may include frame assembly 12 and slide assembly 14, which may surround barrel assembly 16 and cycle in the direction of arrow 18 to load ammunition from ammunition magazine assembly 20 into the chamber (not shown) of firearm 10. Firearm 10 may include grip assembly 22, which may be configured to receive ammunition magazine assembly 20. Firearm 10 may further include front sight assembly 24 and rear sight assembly 26 to aid in aiming firearm 10. Firearm 10 may further include trigger guard 28 that may be configured to shield trigger assembly 30, thus preventing the accidental displacement of trigger assembly 30. Magazine release assembly 32 may be included within firearm 10 to allow for the removal of ammunition magazine assembly 20 from magazine well 34 (as shown in FIG. 3A).

Referring to FIGS. 4-6, there is shown a detail view of firearm 10 with various components of firearm 10 removed (e.g. frame assembly 12 and slide assembly 14, as shown in FIGS. 1-3) to allow for viewing of the various internal components of firearm 10. Trigger assembly 30 may be configured to pivot about pivot point 100 to allow for trigger assembly 30 to be displaced in a counterclockwise fashion (in the direction of arrow 102) as a user (not shown) depresses trigger assembly 30. Alternatively, a non-pivoting trigger assembly (not shown) may be utilized within firearm 10.

As trigger assembly 30 rotates in a counterclockwise fashion, trigger bar 104 may be displaced longitudinally (in the direction of arrow 106), which displaces sear assembly 108 in a counterclockwise fashion (in the direction of arrow 110), thus disengaging sear assembly 108 from hammer assembly 112.

Hammer assembly 112 may be biased into the uncocked position (as shown in FIGS. 4-6) via the combination of strut rod 114 and hammer spring 116 (which is held captive between strut rod flange 118 and spring retainer 120). When hammer assembly 112 is placed into the cocked position, sear assembly 108 may hold hammer assembly 112 in the cocked position (as illustrated via cocked hammer assembly 112′) by releasably engaging notch 122 of hammer assembly 112. Accordingly, when sear assembly 108 is displaced (in the direction of arrow 110), sear assembly 108 may disengage notch 122, resulting in hammer assembly 112 rotating in a counterclockwise fashion (in the direction of arrow 124 due to the bias of hammer spring 116) from the cocked position (as illustrated via cocked hammer assembly 112′) to the uncocked position (as illustrated via hammer assembly 112), which may result in hammer assembly 112 striking firing pin 126 that may impact cartridge 128 and discharge firearm 10.

Referring to FIGS. 7A-7E, 8 & 9, firearm 10 may include magazine safety assembly 150 configured to prevent firearm 10 from discharging when ammunition magazine assembly 20 is not positioned within (i.e., inserted into) magazine well 34. Magazine safety assembly 150 may include pivot point assembly 152 (e.g., a pin assembly) and lever assembly 154. Lever assembly 154 may include first portion 156 and second portion 158. Lever assembly 154 may be configured to pivot about pivot point assembly 152 from an engaged position (as shown in FIGS. 7A-7D & 8) to a disengaged position (as shown in FIGS. 4 & 9). Magazine safety assembly 150 may be configured so that first portion 156 of lever assembly 154 prohibits displacement of trigger assembly 30 when lever assembly 154 is in the engaged position (as shown in FIGS. 7A-7D & 8).

When magazine safety assembly 150 is positioned in the engaged position (as shown in FIGS. 7A-7D & 8), first portion 156 of lever assembly 154 may releasably engage trigger assembly 30 of firearm 10. When magazine safety assembly 150 is positioned in the disengaged position (as shown in FIGS. 4 & 9), second portion 158 of lever assembly 154 may releasably engage ammunition magazine assembly 20 when ammunition magazine assembly 20 is positioned within magazine well 34 of firearm 10. Spring assembly 160 may be configured to bias lever assembly 154 into the engaged position (as shown in FIGS. 7A-7D & 8) when ammunition magazine assembly 20 is not positioned within magazine well 34 of firearm 10.

Magazine safety assembly 150 may be configured so that lever assembly 154 is displaced (in the direction of arrow 160) from the engaged position (as shown in FIGS. 7A-7D & 8) to the disengaged position (as shown in FIGS. 4 & 9) when ammunition magazine assembly 20 is inserted (in the direction of arrow 162) into magazine well 34 of firearm 10. Accordingly, first portion 156 of lever assembly 154 may be configured to disengage trigger assembly 30 when ammunition magazine assembly 20 is inserted into magazine well 34 of firearm 10 (thus positioning lever assembly 154 into the disengaged position, as shown in FIGS. 4 & 9).

While magazine safety assembly 150 is shown to include first portion 156 of lever assembly 154 that directly engages trigger assembly 30 of firearm 10, other configurations are possible and are considered to be within the scope of this disclosure. For example, first portion 156 of lever assembly 154 may directly engage a supplemental linkage assembly (not shown) that may be configured to directly engage trigger assembly 30.

Having thus described the disclosure of the present application in detail and by reference to embodiments thereof, it will be apparent that modifications and variations are possible without departing from the scope of the disclosure defined in the appended claims.
