  • Patent number: 9457289
    Abstract: A toy gun capable of firing a projectile and simultaneously or near simultaneously, emitting smoke from the muzzle of a barrel of the gun after the projectile has been discharged from the muzzle. The toy gun has first and second rechargeable air pumps, with the first air pump automatically discharging stored air into a breech part of the barrel in order to propel a loaded projectile from the barrel, and the second air pump expelling stored air through a flow restriction device which serves as a pressure switch for actuating a smoke generator located adjacent to the muzzle. The second air pump also provides a low air flow rate through the smoke generator to expel smoke therefrom. The second air pump expels stored air much more slowly than the first air pump. The first and second air pumps are simultaneously triggered to release stored air by a user.

The projectile launching apparatus includes a motor driven linear motion converter, a cylinder, a breech assembly and a compression valve arrangement. The linear motion converter converts a rotational movement of a motor into a linear movement of a piston by a gear reduction mechanism. The linear movement of the piston within the cylinder compresses a gas with a high compression exponent. The compressed gas is further released into a barrel of the breech assembly through the compression valve arrangement. The compressed gas expands in the barrel causing a projectile to be launched from the barrel with a force of the compressed gas.

The said repositioning set is fixed to the piston set, and will move backward when driven by the gear set. It will then reposition itself by the force of primary repositioning spring. The electric toy guns with this invention have the following advantageous features: Since it has a repositioning set, and air release holes, it provides for motions that are more similar to those of real guns. Thus it is more suited for military training and lasts longer.

  • Patent number: 7958880
    Abstract: A portable batting device that includes a housing, a pneumatically operated ball launching assembly partially disposed within the housing, and a funnel-shaped ball capturing assembly positioned on the top side of the housing. The launching assembly launching a first ball upward into a hitting zone so that a batter may attempt to hit the first ball with a bat. The hitting zone is at a predetermined and adjustable vertical height. The ball capturing assembly receives the first ball should the batter swing the bat and not hit the ball and funnels the first ball into position for a subsequent launch by the launching assembly. The batting device may have a ball feeding assembly operatively associated with the ball capturing assembly.

  • Patent number: 7938110
    Abstract: A ball launcher of the type that includes a piston slidable in a launch tube to increase air pressure behind a ball loaded into a front end of the launcher includes a launch tube of an outwardly flared construction to a diameter greater than the diameter of the ball loaded into the launcher. The outwardly flared end has an inwardly directed peripheral ledge defining an aperture smaller than the ball diameter. A spring located within the flared end biases the loaded ball against the ledge to create and maintain a pneumatic seal between the ball and ledge prior to launch.

  • Publication number: 20110041824
    Abstract: A toy for launching two or more projectiles employing a central shaft cocking mechanism for rapid fire projectile launching through quick, simple and fun cocking and triggering mechanisms. The toy includes a housing assembly, a projectile device disposed about the housing with two or more projectiles, a piston and cylinder assembly. The piston is secured to the housing in a fixed position and the cylinder is slidably mounted on the piston, a cocking mechanism in mechanical communication with the piston and cylinder assembly including a shaft extending through the projectile device for engagement with the cylinder capable of moving the cylinder to a cocked position. A trigger mechanism is secured to the housing capable of advancing the projectile device to a firing position and capable of releasing the cylinder from a cocked position to advance the cylinder on the fixed piston and discharge a burst of compressed air launching a projectile.

  • Patent number: 7882829
    Abstract: The present device is a launcher for a projectile, comprising an enclosure that is adapted to be held by a human hand. The enclosure comprises a barrel aperture, a pump aperture, and a trigger aperture. The launcher further comprises a pump assembly that comprises a pump piston traversing the pump aperture. The pump piston is configured to be actuated by a user and can be reciprocated in and out of a pump cylinder. The launcher comprises a compression chamber in fluid communication with the piston cylinder through a check valve that only allows air to pass from within the piston cylinder into the compression chamber. The launcher comprises a trigger that opens the compression chamber and sends compressed air into a barrel that can have a projectile stored therein. The trigger is configured to be manually operated by a user. The barrel is in fluid communication with the compression chamber through a trigger valve.

  • Patent number: 7878184
    Abstract: A hardball weapon for use in exercises or shooting games and designed as military gun is made with a weapon housing (3) containing two coaxial pistons (21, 26) which are mounted directly in the weapon housing (3) and driven by an electric motor (10) via a gear wheel mechanism (12, 18) and toothed racks (24, 25). The first outer piston (21) functions as a movable bolt for loading the cartridge chamber with cartridges (7) with solid balls (6), and the other piston (26) functions as a pressurised air piston for creating an overpressure for firing the balls (6). The weapon housing (3) can be opened by pivoting, thereby giving access to the parts in the firing mechanism for inspection, repair and adjustment.

  • Patent number: 7854221
    Abstract: A gas spring having an internal vibration damper for an air gun charging system. The gas spring including a relatively thin liner which is received within and abuts the elongated inner and/or outer wall of the tubular gas spring. The liner(s) absorbs vibration in the air gun to improve firing performance. A guide sleeve mounted to the outer surface of the gas spring abuts an air gun's tubular compression piston to transfer any vibrations in the compression piston to the liner. A tubular counter-weight is slidably mounted about the outer wall of the gas spring and strikes a forward end of the charging system after the air gun is fired to counter the post-firing recoil.

  • Patent number: 7793643
    Abstract: An ejecting toy mainly includes a cylinder body with a receiving chamber. A front end of the cylinder body is covered by a front cover. A vent hole is formed at a middle position of the front cover and at least one air inlet hole is formed at a periphery of the front cover. A front end of the vent hole is sealed by an elastic object. A rear end of the front cover is arranged by a valve, a periphery of the valve has a diaphragm portion with flexibility which is capable of sealing or unsealing the air inlet hole while suffering a force. A handle has a rod body having a piston in a front end of the rod body. The piston can slide back and forth inside the receiving chamber. When the handle is pulled backwards, the diaphragm portion will deform to unseal the air inlet hole to inflow air into the receiving chamber.

  • Patent number: 7730881
    Abstract: A portable motor driven air gun powered by a power source includes a motor that is coupled to a linear motion converter which drives a piston. The piston compresses air in a chamber against a forward air compression valve producing high-pressure air. When sufficient energy is stored within the air stream by the piston, the compression valve opens which releases the compressed air to push a projectile through a barrel. The engagement and disengagement of the linear motion converter and the connected piston to the motor can be controlled using sensors. The linear motion converter further is coupled to a bolt thru a lost motion device to facilitate positioning of the projectile for firing. The direction speed and operative modes of the gun may be controlled with an electric circuit. The power source is preferably rechargeable, allowing the air gun to be operated independent from either a wall outlet or a compressed air supply.
