A barrel catch of a toy gun has a barrel through hole with diameter larger than outer circumference of the barrel so that the barrel penetrates through hole center. The barrel catch includes a barrel fitting portion fitted/attached to the barrel on the inner circumference of the hole opposite to the pressing portion exposed from an opening in a barrel attachment portion of a toy gun body. The barrel catch is housed in a housing portion of the toy gun body slidably in the direction defined by the pressing portion and the opposite portion of the pressing portion. The barrel includes a barrel catch fitting portion fittable to the barrel fitting portion of the barrel catch upon penetration of the barrel through the barrel catch. The barrel slidably penetrates the barrel through hole of the barrel catch in the direction defined by the pressing portion and the opposite portion.

A tripwire launcher. The tripwire launcher includes a housing having a first end opposite a second end. A handle extends orthogonally from the second end. A barrel is affixed to the first end. A tripwire having weighted elements disposed on opposing ends thereof is dimensioned to removably secure within the barrel. A pressurized gas canister is removably securable to the housing, wherein the pressurized gas canister conditionally in fluid communication with the barrel. A quick-release valve is disposed between the barrel and the pressurized gas canister. A trigger is operably connected to the quick-release valve such that when actuated, the quick-release valve opens to deliver gas stored within the pressurized gas canister through the barrel and propel the tripwire from the barrel.

A hand carryable, non-lethal personal protection device using compressed gas for operation. In some embodiments the device uses the compressed gas to create and shoot a vortex of air at the target. In other embodiments, the compressed gas can be used to shoot a burst of atomized water at the attacker. In still other embodiments the device uses the compressed gas to shoot ammunition, such as a ring airfoil, O-ring, bean bag, or other non-lethal blunt trauma munitions at the target. In still further embodiments, the device is modular in its construction, and can be used to apply the compressed gas to various different attachments.

An apparatus includes an energy source and an expansion structure. The energy source is configured to convey an amount of energy operable to increase a pressure of a compressible gas disposed in a chamber. The expansion structure is configured to be placed in fluid communication with the chamber and to receive a flow of the compressible gas in response to the increase in pressure. The expansion structure includes an inlet having a first diameter and an outlet having a second diameter greater than the first diameter and is configured to allow the compressible gas to expand as the compressible gas flows from the inlet to the outlet such that a supersonic free jet of the compressible gas exits the outlet. In some instances, the supersonic free jet of the compressible gas can accelerate, relative to the expansion structure, a projectile disposed outside of the expansion structure.

An electroshock system wirelessly delivers a shock to a subject. The electroshock system may include a launcher, a wireless projectile, a power source, and a wireless power transmitter. The launcher is configured to be grasped by a user. The wireless projectile is configured to detach from the launcher and adhere to a subject. The power source contributes power for the administration of a shock to the subject. The wireless power transmitter delivers said contributed power to the wireless projectile while the wireless projectile is detached from the launcher. The power source and the wireless transmitter may be co-located with the launcher, or may be separate (such as secured to a person or within a vehicle).

A projectile module is attached to a gun component which operates as a system to launch a projectile at a flying device. The gun component is configured to be removably and electro-mechanically attached to a flying vehicle. A cylindrical gas valve is part of the gun component and has a safety component configured on an exterior surface of the cylindrical gas valve to enable the gun component only to attach to the flying vehicle when the projectile module is locked into position. A splitter component configured on the gun component adjacent to the cylindrical gas valve and has an output opening for gas flow. The projectile module is removable and includes weights attached to a projectile, wherein the weights are positioned in channels on the projectile module. The projectile is fired when gas flow is initiated from a reservoir the cylindrical gas valve and splitter component to the channels containing the weights.
