A system for loading BB-shot into an air weapon includes a loader for storing BB-shot having an aperture, a pressure system promoting forced transfer of the BB shot through the aperture, a cartridge with a cylindrical body having axial channels offset by a predetermined angular pitch for housing rows of BB-shot balls, an elastic occluding member for holding the rows of BB-shot balls in the channels, an intermediate cylindrical element having a passage with an inlet communicating with the aperture and an outlet to be longitudinally aligned to one of the channels, a detaching member interacting with the occluding member for locally disabling it at the outlet and allowing a row of BB-shot balls to be transferred into the channel. The cartridge is rotatable about the longitudinal axis relative to the intermediate element for aligning the outlet of the passage with one channel at a time.

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.

A liquid projection bomb includes a shell and is characterized in that functional liquid is filled into the shell, and the shell is made of a soft or hard material easy to crack when bumped. The functional liquid includes water, alcohol, fuel oil, and a solution of water mixed with an extinguishing agent, a fertilizer or a drug.

A system for propelling an air-driven projectile from an air gun includes an air gun with an elongate bore and a source of compressed air in fluid communication with the elongate bore. A projectile is disposed within the bore of the air gun, the projectile having an outer diameter that is less than an inner diameter of the elongate bore.

A toy dart having an elongate dart body of a foam material in a substantially cylindrical shape extending from a head end to a tail end in a first, longitudinal direction, an outer surface of the substantially cylindrical shape having a first ridge proximate the head end; a second ridge proximate the tail end; and one or more recessed areas disposed between the first ridge and the second ridge, where the elongate dart body has a first outer diameter at the first ridge and the second ridge that is larger than a second outer diameter at the one or more recessed areas; and a deformable dart cap affixed to the head end of the elongate dart body.

A hollow spherical projectile is constructed from a plurality of curved structural segments and has a plurality of openings. The projectile can be fired by a conventional paintball marker with a high degree of ballistic accuracy. The projectile is reusable and is fabricated from a flexible and resilient material. The outer surface of the projectile exhibits low friction, achieved by the material itself or by having a low friction coating applied. The projectile possess and transmits less kinetic energy than a conventional paintball and therefore inflicts less pain and damage upon impact. Fabrication can be accomplished by 3D printing, or molding as a single seamless piece, or as a plurality of pieces which are then assembled.
