20080216806 | BLOWGUN - A blowgun, which is used for firing bullets, comprising: a grip which is comprised a loading gate, a lead pipe, and a guiding flange; a trigger which is installed slidably at the grip, and a interference bar is installed at a part of the trigger, which is formed in the inner of the grip; a mouthpiece which is comprised a tubular part at one end thereof and a conical part at another end thereof; a barrel; a pushing bar which is installed slidably in the lead pipe and can be slid between the mouthpiece and the barrel; and a first recoil spring which is installed in the lead pipe; wherein the lead pipe is formed at the rear of the barrel and through inner of the grip; the loading gate is connected to the lead pipe; the guiding flange is installed in the grip; the tubular part is coupled together with the lead pipe; and during an interval the trigger being compressed, the interference bar of the trigger brings the pushing bar to approach the mouthpiece and to compress the first recoil spring until a chamber which is connected to the loading gate between the pushing bar and the barrel is enough for containing the bullet, and then the first recoil spring returns and brings the pushing bar to approach the barrel and to push the bullet into the barrel while the interference bar contacts with the guiding flange and releases the pushing bar. | 09-11-2008 |
20090007895 | APPARATUS FOR LAUNCHING SUBCALIBER PROJECTILES AT PROPELLANT OPERATING PRESSURES INCLUDING THE RANGE OF OPERATING PRESSURES THAT MAY BE SUPPLIED BY HUMAN BREATH - A blowgun for efficiently and accurately launching subcaliber projectiles comprises:

20090159062 | Spirometer Toy - 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. | 06-25-2009 |
20110132343 | RAPID FIRE BLOW GUN TOY - A blow gun includes a hollow ammunition chamber having an internal volume that is large enough to hold at least 30 spherical projectiles, for example plastic BBs. The ammunition chamber has a breath receiving orifice, and a firing port. A barrel obtrudes from the hollow ammunition chamber through the firing port. The barrel has a cylindrical bore therethrough, that defines an internal diameter that is greater than the spherical projectile diameter but no greater than 1.7 times the spherical projectile diameter. The barrel has an outer surface that is in sliding contact with the firing port. The barrel may have a storage position in which most of the barrel is disposed within the internal volume of the hollow ammunition chamber, and a firing position in which most of the barrel is disposed outside of the hollow ammunition chamber. | 06-09-2011 |
20130042850 | BB PEASHOOTER - A kit for shooting a BB through a peashooter, comprising a tubular peashooter with an opening in the tube that has an opening diameter, inner and outer walls, a tube thickness, and a tube length, and a BB with a BB diameter. | 02-21-2013 |
20130167820 | SPORT BLOW GUN - A sport blow gun is a blow gun which is a tube with a bore, a loading end and a muzzle end. A projectile is inserted into the loading end and blown out the muzzle end by the user's breath. The main tube features a safety device which prevents a projectile from falling out of the tube or being inhaled. One type of projectile fired from the blow gun is a dart which is usually comprised of foam or soft material, and may also be made out of a material which causes relatively little resistance as it passes through the bore, yielding higher velocity. The projectile may also be coated with a coating which reduces resistance with the bore. Projectiles may also be modified in form for aerodynamic efficiency. | 07-04-2013 |
20130180513 | MULTIPLE SOFT PROJECTILE BLOW GUN - 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. | 07-18-2013 |
20130213376 | APPARATUS FOR LAUNCHING SUBCALIBER PROJECTILES AT PROPELLANT OPERATING PRESSURES INCLUDING THE RANGE OF PRESSURES THAT MAY BE SUPPLIED BY HUMAN BREATH - An apparatus for efficiently and accurately launching subcaliber projectiles comprises:
| 08-22-2013 |
20130213377 | APPARATUS FOR LAUNCHING SUBCALIBER PROJECTILES AT PROPELLANT OPERATING PRESSURES INCLUDING THE RANGE OF PRESSURES THAT MAY BE SUPPLIED BY HUMAN BREATH - An apparatus for efficiently and accurately launching subcaliber projectiles comprises:

20150083100 | TOY RIFLE WITH ADJUSTABLE BLOWPIPE - A toy rifle and method for recreational warfare having a blowpipe disposed in the rifle body with an adjustable offset mouthpiece to permit shooting projectiles from the blowpipe while holding and aiming the rifle body. | 03-26-2015 |
20160146568 | TRIGGER MECHANISM FOR TOY BLOWGUN - 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. | 05-26-2016 |
