The invention provides a toy that functions to propel a projectile through a tube at someone or something by exerting sufficient air pressure from the user's lungs through the tube. This action has the effect of challenging and building the user's respiratory system, including the respiratory musculature and lung capacity, through the repeated use of the toy.

A blowgun has a movable mouthpiece coupled to a barrel, wherein a soft, and preferably fluid-soaked projectile is inserted into the barrel through the mouthpiece via a continuous channel that is formed by the mouthpiece and the barrel. After loading of the projectile, the channel is closed by moving the mouthpiece relative to the barrel.

A projectile launcher comprising an elongate barrel provided with a bore, a magnetic detent, an associated discarding sabot, and an associated subcaliber projectile. Pending launch, the magnetic detent exerts a magnetic restraining influence to hold the subcaliber projectile inside the bore within proximity of the sabot. Launch thrust overcomes the magnetic restraining influence of the detent upon the projectile, and the sabot separates from the projectile after launch under the influence of atmospheric drag.

A blow gun assembly allows the rapid continuous firing of multiple soft, cylindrical projectiles using a single breath. The assembly includes at least one soft cylindrical projectile with a height generally equal to or slightly greater than its diameter, and a centrally-located breech in fluid communication with a mouthpiece, a vertical magazine, and a barrel. Projectiles loaded into the magazine enter a breech chamber by gravity. Upon receiving a charge of air through the mouthpiece, the projectiles travel successively through the breech chamber and out through the barrel in rapid fashion. Sizing of the magazine, breech chamber, and barrel, relative to the projectile, causes the projectiles to flow through the blow gun in continuous succession without jamming, with projectiles being rotated within the breech chamber to properly align with the barrel.

A blow gun for launching soft projectiles. The blow gun includes an action sleeve which is wrapped around and attached to a receiver. Soft projectiles, such as marshmallows, may be loaded into the breech of the blow gun by rotating the action sleeve approximately a quarter of a turn around the receiver. When rotated in this manner, a loading port in the action sleeve aligns with a corresponding loading port on the receiver, thus exposing the hollow interior of the receiver. A barrel is attached to one end of the receiver so that the hollow interior of the barrel and the hollow interior of the receiver are aligned. A muzzle brake extends beyond the barrel and has a plurality of brake vents to prevent the accidental inhalation of projectiles when inhaling on the muzzle end of the blow gun. The blow gun may be fired by blowing into a blow tube which is fluidly connected with the receiver.

The present invention relates to a sucker and an adhesion arrow having the same. More particularly, the present invention provides a sucker that can be attached, instead of a needle, to an arrow for a toy arrow shooter. The sucker of the present invention is formed with an annular projection on an adhesion surface of the sucker. Thus, even when the sucker collides against a target at a high speed, the sucker can be prevented from bouncing back from the target due to a repulsive force generated from the collision and thus securely adhere to the target. Further, even though the sucker of the present invention flies and collides against the target at a certain angle, the sucker can easily adhere to the target. Further, the sucker is made of a soft material so that a repulsive force can be smaller than an adhesion force when the sucker collides against the target. When a user shoots the adhesion arrow of the present invention by blowing it received in a shooting tool, the sucker is not caught by an inner circumferential surface of the tubular shooting tool so that the adhesion arrow of the present invention can be easily shot.

A line launcher (110) capable of firing a projectile (117) and an attached line (125) up to about 70 metres. It has a barrel (113) large enough for a resilient projectile attached to a line. It has a pre-charge chamber capable of storing a pressurised gas from a pressurised gas cartridge. A trigger mechanism vents the gases in this pre-charge chamber into the barrel to expel the projectile and line. Gas from the pressurised gas cartridge (e.g. a CO2 bulb) is released slowly enough to pressurise the pre-charge chamber but without the cartridge freezing as might occur if the gas was discharged directly from the cartridge into the barrel to directly propel the projectile.

A springless shooting dart composed of a hollow cylinder, a shuttle, a rope, and a dart is provided. Inside the hollow cylinder is a shuttle. A dart can be disposed at the front end of the shuttle. The shuttle is connected to a rope having one end tied to the user's waist. A user can control the dart to be shot out by holding on to the cylinder and extending from his arm.

An adapter system that transforms a blowgun into a fishing blowgun is provided. The fishing blowgun adapter system includes a reel mounting system which is used to selectively secure a fishing reel along a barrel of the blowgun. The present invention also embodies a plurality of fishing line eye guides spaced apart the barrel from largest to smallest at or near the distal end of the blowgun. Furthermore, using the fishing line eye guides instead of a fishing rod (prior art) eliminates the danger of spring-loaded backlashes of earlier makeshift solutions. Once the fishing blowgun adapter system has been operatively associated with the blowgun, the transformation into a fishing blowgun is complete.

A trigger mechanism for a toy blowgun wherein the toy blowgun comprises: a launching mechanism for launching a projectile from the toy blowgun; and a locking mechanism for locking the launching mechanism in a primed configuration, the locking mechanism being releasable to launch the projectile from the toy blowgun. The trigger mechanism comprises: a trigger chamber having an inlet for receiving a flow of air; and a shuttle movable from a start position to a launching position in the trigger chamber by the flow of air to release the locking mechanism.

A water penetrating blowgun dart is provided. The blowgun dart has a funnel removably attached to a tail end of the dart shaft so that upon contact with a water surface, the funnel moves from an engaged configuration to a disengaged configuration. The tail end may provide a slot for snugly receiving an eye, wherein the tail end and the eye have cooperating grooves so that when in the engaged configuration, the eye and tail end are secured with a filament that slightly protrudes from the flush outer surface of the shaft and eye. The protruding filament frictionally engages the funnel in the engaged configuration so that the funnel remains engaged with the shaft prior to hitting the water's surface.

A pressure detection device for a blowgun has a housing and a pressure-sensing unit. The pressure-sensing unit has a pressure sensor integrated circuit (IC) aligned with a pressure-sensing opening of the housing to detect air pressure inside the blowgun and outputting a voltage signal corresponding to the detected air pressure, a micro-controller unit (MCU) converting the voltage signal into a detected datum, and performing calibration and calculation with the detected datum to generate a blow-off pressure value displayed on a display screen, and a power-saving control circuit activating power supply to the pressure sensor IC and the MCU and shutting down power supply thereto when users are done with blowgun shooting.
