Description

CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of U.S. Provisional Patent Application No. 63 / 747,260, filed January 20, 2025; U.S. Provisional Patent Application No. 63 / 752,048, filed January 31, 2025; and U.S. Provisional Patent Application No. 63 / 786,604, filed April 10, 2025. The entire contents of each of the foregoing applications are incorporated by reference herein for all purposes to the extent not inconsistent with the present disclosure.FIELD OF DISCLOSURE

[0002] The present disclosure relates to trigger mechanisms and, more particularly, to trigger assemblies configured to reset in coordination with cycling of associated firearm components.BACKGROUND

[0003] Typical semi-automatic trigger mechanisms require a user to release the trigger to allow the mechanism to reset for a subsequent actuation. In such systems, a single pull of the trigger results in a single discharge event, and maintaining the trigger in a pulled position will not initiate additional discharge events. In various use contexts, including recreational and competitive target shooting, users may desire faster follow-up shots and consistent trigger reset behavior.

[0004] In many platforms, the achievable cadence of successive shots may be limited by the reset characteristics of the trigger mechanism and the mechanical relationships among the trigger, sear, disconnector and associated cycling components. The limitations may vary across firearm platforms and configurations.

[0005] There remains a need for trigger assemblies that provide repeatable and reliable reset behavior, that can be configured for use with different host platforms, and that may be installed with little or no permanent modification to the host platform and removed to return the host platform to a stock configuration.SUMMARY OF THE DISCLOSURE

[0006] The present disclosure provides, among other things, resetting trigger assemblies and related components configured to reset in coordination with cycling of one or more associated components of a firearm. In some embodiments, the assemblies are configured to eliminate or reduce a requirement that a user fully release the trigger for the trigger mechanism to return to a reset state. In some embodiments, the assemblies are configured to permit installation in existing host platforms with little or no permanent modification and to be removable for return to stock configuration.

[0007] In some embodiments, a resetting trigger assembly includes a trigger, a sear or sear-equivalent member, and one or more members that selectively permit or block rearward movement of the sear during selected portions of a cycling sequence. In some embodiments, the assembly cooperates with a bolt carrier, slide, hammer, striker, or other cycling component such that cycling motion drives at least one member of the resetting trigger assembly toward a reset condition.

[0008] In some embodiments, a first family of embodiments is implemented in a bullpup-style platform (e.g., an AUG-type platform) and includes a sear having one or more angled rails configured to cooperate with hammer movement to urge the sear forward during cycling. In some embodiments, a sear release arm and a sear catch cooperate to selectively permit rearward sear movement when the firearm is in battery and to block rearward sear movement when out of battery.

[0009] In some embodiments, a second family of embodiments is implemented in a striker-fired pistol-type platform (e.g., a Glock-type platform) and includes a switch or selectable element configured to provide a first setting in which the host platform operates substantially as stock and a second setting in which a portion of the assembly urges a link bar or trigger forward during a portion of the cycling sequence.

[0010] In some embodiments, a third family of embodiments is implemented in a rifle-type platform (e.g., a SCAR-type platform) in which a trigger is directly reset by a bolt carrier and a blocking member (e.g., a slider or trigger catch) cooperates with a release arm to inhibit trigger actuation until the bolt is in battery.

[0011] In some embodiments, a fourth family of embodiments is implemented in a roller-delayed platform (e.g., an HK-type platform) in which a trigger is directly reset by a bolt carrier and a trigger catch cooperates with the bolt carrier to inhibit trigger actuation until the bolt is in battery. In some embodiments, a disconnector assembly provides selectable modes of operation and is configured to engage a hammer in a first selector position and be moved out of engagement in another selector position.

[0012] Other embodiments include combinations and variations of the foregoing, including rotating and reciprocating (translating) sear catches, different biasing arrangements, different interface geometries, and optional anti-friction features (including, in some embodiments, a rolling element such as a bearing).

[0013] These and other features will be apparent from the description and drawings, and from the claims.BRIEF DESCRIPTION OF DRAWINGS

[0042] In general, the disclosure relates to resetting trigger assemblies that cooperate with one or more cycling components of a host platform. The resetting trigger assembly can be configured as a module receivable in a trigger housing and arranged to provide a repeatable reset sequence. In some embodiments, the resetting trigger assembly includes one or more members configured to inhibit actuation until a cycling component is in battery, and one or more members configured to urge a trigger member toward a reset condition during cycling.

[0043] Unless expressly stated otherwise, features of one embodiment may be combined with features of another embodiment.Rotating Resetting Trigger Embodiments

[0044] Referring to FIGS. 1-2, illustrates an embodiment of the rotating resetting trigger 10 of the present disclosure. Trigger 12 is disposed with a firearm, for example, the Steyr AUG® manufactured by Steyr Arms GmbH & Co. KG of Austria. Trigger 12 rotates about trigger pin 20 through its arc of motion. The arc of motion includes a stationary position and a firing position. Trigger 12 is typically configured to engage a user’s finger, though other configurations of trigger 12 are contemplated.

[0045] Trigger release lever 16 engages a portion of the trigger 12 and rotates about trigger release lever 16 and trigger pin 20. Trigger release lever 16 is typically spring loaded to return a first position that engages the trigger 12. Hammer 14 is disposed adjacent to trigger 12 and engages hammer release lever 18. Hammer release lever 18 rotates about hammer release lever pin 24.

[0046] Pulling trigger 12 causes the hammer 14 to catch the rear of the firearm, allowing hammer 14 to strike the firing pin (not shown). The bolt of the firearm, not shown, moves rearward within the firearm and forces the hammer 14 into the catch of the hammer 14. This movement then causes the trigger 12 to move forward and retains the hammer 14. In embodiments, in situations where the bolt is out of the battery of the firearm (i.e., no round in is in the chamber and the bolt is not pushed against the firearm barrel / trunnion), trigger 12 cannot be pulled by the user because the catch of the hammer 14 has not had the release catch 26 engage, which rotates about release catch pin 22.

[0047] In embodiments, the bolt may move forward to allow for the trigger release lever 16 to rotate upwards, moving the release catch so that the release catch is not obstructing the catch of the hammer 14, thereby releasing the hammer 14 to strike the firing pin of the firearm. The cycle then repeats as long as the trigger 12 is pulled by the user.

[0048] In embodiments of the rotating resetting trigger of the present disclosure, in the case of the Steyr AUG A1 and / or other rifles, the hammer and catch mechanism include a catch component that holds the hammer in place. The hammer interacts with specific contact points, pushing the trigger forward when it comes down. In embodiments of the rotating resetting trigger of the present disclosure, in the case of the Steyr AUG A1 and / or other rifles, the trigger pins, in this embodiment for the Steyr AUG A1, the trigger pins, which may be approximately 10 inches long, transmit the trigger's motion from the forward position to the mechanism located farther back.

[0049] In embodiments of the rotating resetting trigger of the present disclosure, in the case of the Steyr AUG A1 and / or other rifles, may include the following bolt carrier group Interaction. The bolt carrier group may slide on a specific component, depending upon the rifle and its configuration. When the bolt moves forward, it may disengage the hammer catch by pivoting this component upward and backward.

[0050] In embodiments of the rotating resetting trigger of the present disclosure, in the case of the Steyr AUG A1 and / or other rifles, pivots and springs may include pivot points and springs that facilitate movement. For example, a spring located near a pin may force the trigger and other components into position. The spring may then ensure proper engagement and resets parts as necessary.

[0051] In embodiments of the rotating resetting trigger of the present disclosure, in the case of the Steyr AUG A1 and / or other rifles, the trigger actuation may occur as follows: a user may pull the trigger, which then disengages the catch holding the hammer, allowing the hammer to move forward. This configuration ensures that the hammer is retained until the trigger is pulled again.

[0052] In some embodiments, device 10A is configured for use with a Glock-type pistol platform, device 10B is configured for use with an M2 Browning-type platform, and device 10C is configured for use with a Kriss Vector-type platform, each as non-limiting examples of host platforms with which the disclosed resetting trigger concepts may be implemented.

[0053] Referring to FIGS. 3-16, a rotating resetting trigger assembly 110, 120 that includes a trigger member configured for user actuation, a hammer interface portion configured to cooperate with a hammer or striker mechanism, and one or more intermediate members (e.g., a release lever, catch, or linkage) configured to control a release condition and / or to promote reset behavior. In some embodiments, one or more of these members rotates about a corresponding pivot pin to define an arc of motion between a ready state and an actuated state.

[0054] In some embodiments, the resetting trigger assembly may include a reciprocating trigger sliding relocating bar 200, a hammer 202, a disconnector 204, a trigger 206, a portion of a disconnector for a rotating trigger catch 208, a sub-portion 210 of catch 208, an alternate hammer 212, a rotating trigger catch 214.Trigger member and pivots.

[0055] In some embodiments, the trigger member rotates about a trigger pin during actuation. In some embodiments, an intermediate release lever (or equivalent member) is configured to rotate about its own pivot and is biased (e.g., by a spring) toward a position that promotes engagement of a catch surface during a reset sequence.Hammer interaction and cycling-driven reset.

[0056] In some embodiments, pulling the trigger member causes a hammer to be released to strike a firing pin (or to initiate a discharge event). During cycling, a cycling component causes the hammer to be driven to a retained condition. In some embodiments, motion of the hammer and / or cycling component cooperates with a contact surface of the resetting trigger assembly to urge at least one member of the assembly toward a forward / reset condition.Out-of-battery gating (optional).

[0057] In some embodiments, the resetting trigger assembly includes an out-of-battery gating feature configured to inhibit actuation when a cycling component is not in battery. In some embodiments, a catch condition is not permitted unless a release catch is positioned to allow a release sequence, thereby reducing the likelihood of actuation when a round is not chambered or when the cycling component is not fully in battery.Example host platform interface (non-limiting).

[0058] In some embodiments, the rotating resetting trigger assembly is configured for a bullpup-style host platform (e.g., an AUG-type platform) in which one or more elongated trigger bars or pins transmits trigger motion between a forward trigger location and a rearward trigger mechanism. In such embodiments, the resetting trigger assembly may be configured to cooperate with the geometry of the host platform’s trigger linkage while providing the reset behaviors described herein.Springs, pivot points, and interface surfaces.

[0059] In some embodiments, pivot points and springs are configured to bias one or more members into engagement with corresponding contact points or stop surfaces. In some embodiments, a spring located adjacent a pin biases a lever toward a defined position. In some embodiments, interface surfaces are configured as ramps, rails, angled surfaces, or cam surfaces that cooperate with hammer motion or cycling motion to produce a reset behavior.Reciprocating Resetting Trigger Embodiments.

[0060] Referring generally to FIGS. 8-17, a reciprocating resetting trigger assembly 110 includes a trigger-related member 112 and a reciprocating member configured to translate along a path during at least a portion of a reset sequence. In some embodiments, the reciprocating member moves between a first position and a second position to control engagement of a catch surface and / or to urge the trigger-related member toward a reset condition. FIGS. 10-17 illustrate example component relationships and configurations in side view. These drawings are non-limiting and are intended to show that the reciprocating member may be implemented using different geometries and component interfaces.Host platform examples (non-limiting).

[0061] In some embodiments, components of the reciprocating resetting trigger assembly are configured to interface with a bullpup-style host platform (e.g., an AUG-type platform) and / or a rifle-type host platform (e.g., an H&K-type platform). In some embodiments, the interface is achieved by configuring a contact surface, catch surface, and / or linkage geometry to cooperate with the cycling component(s), hammer movement, and / or existing trigger pack interfaces of the host platform.Additional Rotating Components

[0062] Referring to FIGS. 18-21, additional components of the rotating resetting trigger assembly 10’, 10’’, and 10’’’ are illustrated, including example release lever configurations and hammer configurations. In some embodiments, a hammer release lever includes a first geometry configured to cooperate with a hammer in a first host platform, and in other embodiments includes a second geometry configured to cooperate with a hammer in a second host platform. In some embodiments, a trigger release bar is provided to transmit actuation and / or reset forces through a linkage.Broad coverage statement.

[0063] Although the foregoing embodiments are described with reference to particular example host platforms, the disclosure is not limited to any particular host platform. The disclosed components may be adapted to other firearms by configuring interface geometries and component relationships consistent with the functions described herein.Rotating Resetting Trigger Embodiments (Additional Variants)Rotating embodiment overview.

[0064] Referring to FIGS. 3-7, a rotating resetting trigger assembly (e.g., assembly 110, 120) includes a trigger member configured for user actuation and one or more intermediate members (e.g., a release lever, catch, linkage, or equivalent member) configured to control a hammer release condition and to promote reset behavior. In some embodiments, the trigger member rotates about a trigger pin between a ready state and an actuated state.Release lever and hammer interface.

[0065] In some embodiments, a trigger release lever is configured to engage a portion of the trigger member and is rotatable about a pivot. In some embodiments, the trigger release lever is spring-loaded to return toward a position that engages the trigger member. In some embodiments, a hammer is disposed adjacent to the trigger member and engages a hammer release lever, which is rotatable about a corresponding pivot pin.Cycling sequence and out-of-battery gating (optional)

[0066] In some embodiments, pulling the trigger member causes a hammer to be released to strike a firing pin (not shown). During cycling, a cycling component drives the hammer into a retained condition. In some embodiments, this cycling interaction causes the trigger member to move forward (toward reset) and to retain the hammer until the trigger is again actuated. In some embodiments, when the cycling component is out of battery, the trigger member is inhibited from being pulled by a user because a release catch is not positioned to allow a release sequence.Interface and biasing features

[0067] In some embodiments, when the cycling component moves forward (toward battery), the trigger release lever rotates to change the position of a release catch such that the release catch no longer obstructs a hammer catch interface, thereby permitting release and firing. In some embodiments, pivot points and springs facilitate the movement and return of components to defined positions, and help ensure repeatable engagement during reset.Long-linkage host platforms (illustrative)

[0068] In some embodiments, the rotating resetting trigger assembly is configured for a bullpup-style host platform in which elongated trigger bars or pins transmit trigger motion from a forward trigger location to a rear trigger mechanism. In some embodiments, such linkages may be on the order of several inches long and transmit motion through the host platform housing.Reciprocating Resetting Trigger Embodiments (Additional Variants)Reciprocating embodiment overview

[0069] Referring to FIGS. 8-17, a reciprocating resetting trigger assembly (e.g., assembly 110) includes a trigger-related member and a reciprocating member configured to translate along a path during at least a portion of a reset sequence. In some embodiments, the reciprocating member moves between first and second positions to control engagement between a catch surface and a corresponding contact surface and / or to urge a trigger-related member toward a reset condition.Photographic depiction and component relationship.

[0070] FIGS. 8–9 illustrate example components in photographic form, and FIGS. 10–17 illustrate additional views showing example geometries, interface surfaces, and relative positioning. These drawings are non-limiting and illustrate that the reciprocating member may be implemented using different geometries, spring arrangements, and engagement surfaces.Cross-platform interface capability

[0071] In some embodiments, reciprocating resetting trigger embodiments may be configured for use in multiple host platforms by configuring the engagement geometry between the reciprocating member and a cycling component or a component driven by cycling. In some embodiments, the reciprocating member is biased toward a defined position (e.g., a blocking position or a ready position) by a spring.Rotating Components (Additional Views)Rotating component examples

[0072] Referring to FIGS. 18-21, additional rotating components are illustrated, including example hammer release lever configurations and hammer configurations. In some embodiments, a hammer release lever includes a first geometry configured for a first host platform and a second geometry configured for a second host platform. In some embodiments, a trigger release bar is configured to transmit actuation and / or reset forces through a linkage.Host Platform Adaptations (Illustrative Examples)Striker-fired pistol-type adaptation

[0073] Referring to FIG. 17, an embodiment is illustrated for a striker-fired pistol-type host platform (e.g., a Glock-type platform). In such embodiments, a user actuation of the trigger moves a trigger bar or link bar, which in turn interacts with a striker / firing pin assembly. In some embodiments, the resetting trigger includes a post or interface feature that forces a resetting bar upward and / or rotates during at least a portion of the cycling sequence, thereby urging a linked trigger member toward a reset condition during cycling. In some embodiments, the configuration is arranged to maintain safe operation by conditioning the reset assistance or release on an in-battery state.Belt-fed or heavy-platform adaptation

[0074] Referring to FIG. 18, an embodiment is illustrated for a belt-fed or heavy-platform host platform (e.g., a Browning M2-type platform). In such embodiments, the resetting trigger assembly is configured to interface with the platform’s trigger / hammer mechanism and a cycling component such that cycling drives at least one member toward a reset condition, while optionally inhibiting actuation when out of battery.Delayed-blowback or PCC adaptation

[0075] Referring to FIG. 19, an embodiment is illustrated for a delayed-blowback or pistol-caliber carbine host platform (e.g., a Kriss Vector-type platform). In such embodiments, the resetting trigger assembly is configured to interface with the platform’s trigger mechanism and cycling components to urge the trigger toward a reset condition during cycling, while optionally providing a blocking feature that inhibits actuation unless a cycling component is in battery.AUG-Type Resetting Trigger Embodiments (Sear-Based Reset)

[0076] In some embodiments, the resetting trigger assembly includes a trigger (e.g., trigger 1), a sear (e.g., sear 2), a sear slide (e.g., sear slide 3), a sear release arm (e.g., sear release arm 4), and a sear catch (e.g., sear catch 5) arranged within a trigger housing (e.g., trigger housing 6). In some embodiments, at least one of the trigger, sear, sear slide, sear release arm, and sear catch is configured to cooperate with a cycling component (e.g., bolt carrier 8) and / or a hammer (e.g., hammer 7).

[0077] In some embodiments, the sear is configured to move rearward to release the hammer and forward to retain the hammer. In some embodiments, the sear includes one or more angled rails or ramps configured to interact with hammer movement during cycling. In some embodiments, when the hammer is forced to rotate during cycling, the angled rails urge the sear forward and thereby urge the trigger forward.

[0078] In some embodiments, the sear catch is configured to selectively inhibit rearward movement of the sear during portions of the cycling sequence. In some embodiments, the sear catch is biased toward engagement with a rear portion of the sear to temporarily prevent rearward movement of the sear.

[0079] In some embodiments, the sear release arm is configured to be influenced by the bolt carrier such that, when the bolt carrier is in battery, the sear release arm permits the sear catch to move to a position that allows rearward movement of the sear, and, when the bolt carrier is out of battery, the sear release arm is positioned such that the sear catch inhibits rearward movement of the sear.

[0080] In some embodiments, the sear catch is configured as a rotating member. In other embodiments, the sear catch is configured as a sliding member that reciprocates to engage and disengage a portion of the sear.

[0081] In some embodiments, the sear slide is configured to move relative to the sear to allow a hammer interface during selected states. In some embodiments, the sear slide is biased and includes a spring interface portion. In some embodiments, a pin associated with the sear slide cooperates with the sear release arm to retain a spring.

[0082] In some embodiments, a housing lock and housing lock retainer are provided. In some embodiments, the housing lock is biased and configured to be actuated to allow removal of a housing pin, and the housing lock retainer is configured to prevent the housing lock from unintentionally disengaging from the trigger housing.

[0083] The foregoing description is intended to describe structural relationships and function across cycling states, without limiting the disclosure to a specific geometry, dimension, or host platform.Striker-Fired Pistol-Type Resetting Trigger Embodiments (Selectable Reset Assistance)

[0084] In some embodiments, a resetting trigger assembly is configured for a striker-fired pistol-type host platform and includes a trigger (e.g., trigger 1), a link bar (e.g., link bar 2), a connector (e.g., connector 3), a firing pin (e.g., firing pin 4), a switch (e.g., switch 5), a block (e.g., block 6), a slide (e.g., slide 7), and a frame (e.g., frame 8).

[0085] In some embodiments, the resetting trigger assembly is configured with at least two selectable settings. In a first setting, the assembly is configured such that the host platform operates substantially as stock and the switch is positioned such that it does not meaningfully interact with a firing pin feature during cycling. In a second setting, the assembly is configured such that, during at least a portion of the cycling sequence (for example, while the slide is moving forward), the switch is configured to engage a portion of the firing pin (for example, a tab provided on the firing pin) and urge the link bar and trigger toward a forward / reset condition.

[0086] In some embodiments, the switch is rotatable about a pin within the block and is biased toward a position that provides reset assistance, while also being configured to rotate away from engagement under defined conditions, such as when the host platform is in battery. In some embodiments, the geometry is configured such that the switch disengages to permit normal movement of the firing pin during firing sequences.

[0087] In some embodiments, the mechanism may be shifted or adapted such that the switch engages the link bar directly, including with suitable accommodation in the host platform.Direct Reset Embodiments (Bolt-Carrier Driven Reset) - General

[0088] In some embodiments, the trigger is directly reset by a bolt carrier (or analogous cycling component) rather than indirectly via a hammer-displacement lever. In some embodiments, a blocking member is configured to inhibit trigger movement until the bolt is in battery.

[0089] In some embodiments, the blocking member is a slider. In other embodiments, the blocking member is a rotating trigger catch. In still other embodiments, the blocking member is a reciprocating trigger catch. The blocking member may be biased toward a blocking position and configured to move to a non-blocking position when tripped by the cycling component in battery.

[0090] In some embodiments, the system is configured to reduce the leverage a user can apply against the cycling component during reset, thereby reducing friction and reducing malfunctions induced by excessive trigger force.SCAR-Type Direct Reset Embodiments

[0091] In some embodiments, the trigger assembly includes a trigger (e.g., trigger 1), a hammer (e.g., hammer 2), a trigger release arm (e.g., trigger release arm 3), a disconnector (e.g., disconnector 4), one or more sliders (e.g., sliders 5), a piston interface (e.g., piston 6), a bolt carrier (e.g., bolt carrier 7), and a lower receiver (e.g., lower receiver 8).

[0092] In some embodiments, the trigger is biased toward a forward reset position and is directly urged forward by contact with a portion of the bolt carrier during cycling. In some embodiments, the trigger release arm is biased and is configured to move the one or more sliders between a position that blocks the trigger and a position that clears the trigger. In some embodiments, the trigger release arm includes a spring-loaded piston that bears on a portion of the lower receiver.

[0093] In some embodiments, the disconnector provides an additional mode of operation, including a first selector position in which the user must fully release the trigger to disengage the disconnector from the hammer and a second selector position in which the disconnector is moved out of engagement, thereby allowing repeat actuation under the reset behavior.

[0094] In some embodiments, an optional anti-friction feature is provided, such as a rolling element supported at an end of a trigger reset lever to contact a bottom surface of the bolt carrier.HK-Type Direct Reset Embodiments

[0095] In some embodiments, the trigger assembly includes a trigger (e.g., trigger 1), a trigger catch (e.g., trigger catch 2), a hammer (e.g., hammer 3), a disconnector assembly (e.g., disconnector assembly 4), one or more spring seats (e.g., spring seats 5), a trigger housing (e.g., trigger housing 6), a trigger pack housing (e.g., trigger pack housing 7), and a bolt carrier (e.g., bolt carrier 8).

[0096] In some embodiments, the trigger is biased toward a forward reset position and is directly reset by the bolt carrier during cycling. In some embodiments, the trigger catch is biased toward a position that blocks the trigger and is configured to be rotated or otherwise moved by the bolt carrier when the bolt carrier is in battery so that the trigger may be pulled. In some embodiments, the trigger catch is configured to prevent accidental trigger actuation until a cycling condition is satisfied.

[0097] In some embodiments, the disconnector assembly is configured to engage the hammer in a first selector position and to be moved out of engagement in a second selector position. In some embodiments, when the disconnector is engaged, the trigger must fully reset forward to allow the hammer to transition from the disconnector to the trigger.

[0098] In some embodiments, spring seats are provided to locate and retain springs associated with the trigger catch and disconnector assembly.Additional Variations and Options
