This invention relates to an adjustable gun lock wherein a fan-like mechanism blocks the trigger of the gun and is adjustable to fit a wide variety of firearms.

A toy gun with a two-stage safety includes a gun body, a trigger press member, a two-stage safety and a trigger assembly. The pull handle is placed inside the gun body and includes a first blocker and a second blocker. The trigger press member includes a press block movably engaged with the first blocker. The two-stage safety includes a movable block, a stopper and a swing block. The stopper is movably engaged with the second blocker or returns toward the pull handle. The stopper includes a protruding portion and a protruding pillar. A side edge or a distal end of the swing block is movably engaged with the protruding pillar. The trigger assembly includes a push block and a linkage rod.

A weapon which has a completely modular design. For this purpose, the weapon is subdivided into weapon-specific assemblies which are designed as carrier units of the components and/or of the modular assemblies of the weapon. A first assembly can be a modular weapon housing. Said weapon housing has a carrier unit into which a breech system of the weapon and its components are built. Another modular assembly is a weapon cradle. Into this modular assembly the weapon housing module with breech system is integrated. The weapon housing module can be complemented with the weapon barrel module. The components are connected to the modular assemblies and the modular assemblies to each other by means of rails and guides and complementary rails and guides for the assemblies, by binders and holders, by pins, bolts and quick release fasteners.

A weapon having a barrel cluster, having at least one, preferably multiple, weapon barrel(s) and comprising a bolt, wherein only one of the weapon barrels is oriented in alignment with the single bolt and interacts therewith for the purposes of firing. The barrel cluster has a front, muzzle-side barrel holder and has a rear, bolt-side barrel holder, and has, in a partial region, a control body with a control cam which is incorporated on the circumference. By way of said control cam, the barrel cluster can be adjusted as a whole and independently of the firing of the weapon. The control body is preferably electronically rotated, for which purpose a pin of the actuaor engages into the control cam of the control body.

Crossbows having two trigger safety locks. Operatively connected to a trigger is a trigger lock element that in one position prevents the trigger from moving. To prevent inadvertent contact between a cocking slide and a released stretched cord of the crossbow, a slide lock element engages the trigger lock element until the slide lock element is disengaged by the cocking slide moving out of the way. To prevent an improperly configured projectile from being discharged a projectile lock element engages the trigger lock element until a properly configured projectile is loaded onto a drum causing the projectile lock element to disengage from the trigger lock element.

The invention disclosed herein provides a system and a method for a single-use firearm and personal defense system, with an imbedded electronic device for tracking and control of the firearm. The system includes a single-use firearm capable of firing a projectile. The single-use firearm capable of firing a projectile comprises a firearm frame, at least a first barrel, a trigger operable to actuate a striking of at least a first ammunition cartridge, and an ammunition locking system, wherein the ammunition locking system permanently locks the at least first ammunition cartridge within the firearm, whereby once locked, the at least a first ammunition cartridge may not be removed or reloaded without permanently damaging the firearm. The system also incorporates internal electronics for, among other things, tracking, notifying, and monitoring the firearm and its users.
