US12716671 - Feeding mechanism and method for toy projectile launcher

A toy launcher including a housing, a storage cartridge configured for placement into an opening of the housing, with projectiles within the storage cartridge held in a first orientation, a cocking slide movably attached to the housing between a first position and a second position, a reciprocating frame operatively connected to the cocking slide, a projectile housing pivotably attached to the toy launcher housing adjacent to the storage cartridge, and a reciprocating feed lever operatively connected to the reciprocating frame. Movement of the cocking slide from the first position to the second position in a first priming step and then back to the first position in a second priming step causes the feed lever to push a projectile from the storage cartridge into the projectile housing, pivots the projectile housing so that the projectile is in a second orientation, and places the projectile in the second orientation at a firing position within the toy launcher.

US12716672 - Machine gun trigger assembly

A trigger lever assembly includes a link rotatable between a first position and a second position. The link has a first leg extending from an axis of rotation to a first end portion and a second leg extending from the axis of rotation to a second end portion. A trigger lever is mounted to the first end portion of the link and is rotatable between a blocked position and an unblocked position. The trigger lever is biased toward the blocked position. In the blocked position, a second end portion of the trigger lever contacts a first protrusion on the link. On the other hand, when the trigger lever is in the unblocked position, the second end portion of the trigger lever abuts a second protrusion on the link. The assembly can be part of a spade grip assembly or part of a complete machine gun.

US12716673 - Synthetic trigger system

The present disclosure provides systems and techniques for a trigger system that can be implemented in a gun. The trigger system may include a trigger body affixed to a pivot, a trigger detent affixed to the pivot, and a detent biasing device configured to bias the trigger detent away from the trigger body such that a detent surface protrudes from the trigger body. The trigger detent may be moveable along a displacement path, and an obstructing surface that is configured to remain substantially stationary relative to the trigger detent may be located in the displacement path of the trigger detent. The trigger detent may be configured to contact the obstructing surface while moving along the displacement path, move linearly away from the obstructing surface by compressing the detent biasing device, and move past the obstructing surface based on a threshold amount of force being applied to the trigger body.

US12716674 - Mortar training system for simulated firing

A mortar training device includes a barrel body including a bore; a shot detector contained in the barrel body and including a shot detection sensor and configured to output an electronic signal indicating a firing of an inert mortar projectile from the barrel body; a battery; a plurality of orientation sensors contained in the barrel body; and one or more processors and memory storing instructions that, when executed by the one or more processors, cause the one or more processors to receive the electronic signal from the shot detection sensor indicating that an inert mortar projectile is fired from the barrel body, and determine an elevation of the barrel body and an azimuth of the barrel body when the inert mortar projectile is fired from the barrel body based on sensor data received from the plurality of orientation sensors.

US12716675 - Firearm training system and method utilizing distributed stimulus projection

Systems and methods are disclosed herein to improve efficiency and effectiveness in firearms and tactical training, at least in part by selectively generating images onto external target elements. One or more portable devices are selectively mounted with respect to selected ones of the external target elements, which may be fixed in position or mobile as the application demands. Each device includes a housing accommodating and configured for optical projection of light from an array of laser sources and diffractive optical elements. A device controller directs the projection of light from one or more of the laser sources according to a programmed dynamic target stimulus arrangement. The device controller may be individually and manually programmed or commanded in some embodiments, but alternatively a master controller may be implemented to coordinate light projections from an array of devices to provide any number of desired scenarios for neurological and/or physiological stimulation of users.

US12716676 - Toy projectile launcher and apparatus

Apparatus and methods employing dual launch and/or non-launching secondary functions configuring operation of launchers as between one of a first or a second position. Handle portions to the outer housing may be used for grasping the toy launcher with a user's hand, and a trigger may be used in launching the projectiles or amount of launchable matter. An exit aperture disposed in relation to a forward end of the outer housing, with the exit aperture being in general alignment with the chamber such that upon use of the trigger launching is provided with forward momentum through the exit aperture. A manual actuator is disposed in relation to the one or more handle portions of the outer housing for optional use to actuate a feature of the toy launcher to reconfigure, adjust, or actuate the launcher.

US12716677 - Bushings for archery bows and related apparatuses

An archery bow includes a riser and a bushing coupled to the riser. The bushing includes a bore, a drive feature, and a threaded feature. The drive feature is disposed within the bore. The threaded feature is disposed between the aperture and the drive feature. The bushing can include a body having a first end and a second end. A flange can be formed or defined at the first end. The drive feature can be disposed at the second end. The threaded feature can be internally disposed within the bore. The bushing can have an external threaded feature.

US12716678 - Compound bow including adjustable limb pocket

A compound bow includes a riser, a limb pocket on the riser, and a first limb member and a second limb member supported by the limb pocket. The limb members each extend from a first end at the limb pocket to a second end distal to the limb pocket. The limb members each have an inner surface facing the riser and an outer surface facing away from the riser. The limb pocket abuts the outer surfaces of the limb members at the first ends of the limb members and abuts the inner surfaces of the limb members between the first end and second ends. Independently adjustable adjustment devices are supported by the limb pocket and abuts the distal ends of the limb members to independently adjust the position of the first end of the limb member relative to the limb pocket.

US12716679 - Flexible latch for trigger device

A trigger device is described comprising a string hook, a trigger, a sear, and a flexible latch. The string hook is configured to retain a bowstring. The sear is coupled to the trigger and configured to release the string hook in response to actuation of the trigger. A flexible latch is coupled between the string hook and the sear. The flexible latch has a flexure design configured to flex in response to a holding weight applied by the bowstring, wherein flexure of the flexible latch reduces a pull weight of the trigger.

US12716680 - Pneumatic launching apparatus with positioning of plural rounds from breech to alignment passages of barrels and methods

Launcher apparatus and methods for toy projectile blaster air compression element cylinders with elongated breech bolts for fluid communication in alignment with projectile launching barrels capable of receiving and positioning two or more rounds advanced within the barrels from breech bolts. The piston is primed and prevented from advancing once retracted with a lock and catch mechanism. An interlock and pathway prevents subprime strokes. The air compression element receives the piston for generating fluid communication to outwardly launch received projectile rounds. The breech can receive projectiles with the breech bolt of the air compression element extending into the breech to position received projectiles into barrels.
