  • Patent number: 11686550
    Abstract: A shooting toy includes a gun body defining a bullet loading position and a launching position, a bullet loading device rotatably arranged on an outer side of the gun body, a pumping device communicated with the launching position, and a rotating device rotatably arranged in the gun body. The rotating device defines bullet accommodating cavities. The rotating device drives the bullet accommodating cavities to rotate in the gun body, so that the bullet accommodating cavities rotate to the bullet loading position and the launching position in turn. The bullet loading device loads soft bullets to the bullet loading position during a rotation process, so that the soft bullets are loaded in the bullet accommodating cavities. The pumping device pumps pressurized air to the launching position, so that each of the soft bullets is shot from the launching position under driving of the pressurized air.

  • Patent number: 11644271
    Abstract: The present invention discloses a toy gun, and relates to the technical field of toys. In the present invention, a driving mechanism drives a gear set to rotate, and the gear set drives a piston to move reciprocally in a cylinder body, so that the piston compresses air in the cylinder body, and high-pressure air is ejected from an air nozzle. After a gel ball is loaded into a gun barrel, since the air nozzle is inserted at one end of the gun barrel, the compressed air ejected from the air nozzle pushes the gel ball out of the gun barrel, thereby realizing the firing of the gel ball. Compared with the toy gun that cannot fire bullets in the traditional art, the present invention improves the playability.

    Abstract: A toy projectile launcher for launching a projectile from a housing having a trigger mounted to the housing which can be depressed to actuate a motor. A mechanical linkage operatively interconnects the motor with an actuator which generates a source of pressurized air upon movement of the actuator from its cocked to its un-cocked position to effect automatic repeated movement of the actuator to its cocked position and release from its cocked position. Repeated intermittent sources of pressurized air are generated for sequential launching of projectiles. Disclosed embodiments also include a toy projectile launcher having an air passageway through which compressed air is passable to a plurality of sequential projectile holders holding respective projectiles to be launched. The projectile holders are advanced into operative launching engagement with the air passageway sequentially by an advancing mechanism.

  • Patent number: 8113188
    Abstract: A toy gun includes a body, a piston adapted to move relative to the body between an extended position and a retracted position and to be moved rapidly toward the retracted position during a firing stroke. A number of firing chambers each receive a projectile and air compressed by the piston during a firing stroke to fire the projectile from the toy gun. An air delivery mechanism conveys the compressed air to one of the firing chambers and co-operates with the piston to advance as a result of piston movement to a configuration whereat it can convey compressed air to another of the chambers.

  • Publication number: 20120024279
    Abstract: An air-powered toy gun is described. The toy gun includes a housing with a barrel. A cartridge slot is formed in the housing to accept a projectile cartridge and align a bullet chamber of the cartridge with the barrel. An air cylinder is attached with the housing. A dual slide unit is slideably attached with the housing, the dual slide unit having a plunger positioned within the air cylinder. Further, a pull back handle is attached with the dual slide unit to allow a user to draw the plunger from the air cylinder. Finally, conduits are attached with the air cylinder to connect the air cylinder with the bullet chamber of a cartridge. Thus, a user can draw the plunger from the air cylinder and release the pull back handle to shoot a projectile from the toy gun.

  • Patent number: 8087405
    Abstract: A projectile launcher for launching soft projectiles. The projectile launcher features a pump assembly having a cylinder and piston. The piston includes a pump grip so that a pressure charge is generated when the user moves the piston. The pressure charge is released into a chamber which contains a soft projectile. The chamber includes a radius bend joining a projectile receiving orifice to a projectile discharging orifice. The pressure charge is introduced proximate the apex of the radius bend.

  • Patent number: 8074392
    Abstract: A toy rifle (air soft rifle, BB-rifle) backlash vibration structure is disclosed formed of a receiver extension, a weight, a reaction spring and a buttcap spacer. The weight has a front extension inserted through the frame of the toy riffle and connected to the rear end of the piston spring at the rear side of the piston so that the component parts of the backlash vibration structure does not touch the piston during movement of the piston. The buttcap spacer is detachably fastened to the rear side of the receiver extension and mounted with an adjustment screw rod that is rotatable relative to the buttcap spacer to adjust the level of the backlash vibration from zero to the maximum.

  • Patent number: 7963281
    Abstract: This invention is a motion control mechanism for use in electric toy guns. The mechanism includes a gear set, a piston set that is inside the electric toy gun's body and driven by the said gear set, a primary repositioning spring that is between the said piston set and the toy gun's rear end, and the repositioning set that is installed on the gun body, and moves backward when driven by the said piston set. 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: 7931016
    Abstract: A paper bullet firing pistol toy produces its own projectiles sequentially for shooting. By sliding an operating part on the outside of the toy, a strip of paper is drawn into the body of the pistol, and a piece of the paper is cut and folded into a bullet shape inside the toy. Thereafter, the paper bullet is shot from the muzzle by operating the trigger part, and the toy's mechanisms can be restored to their initial states by restoring the sliding operating part to its initial position, thereby making it possible to shoot paper bullets continuously.

  • Publication number: 20110017186
    Abstract: An air gun including a trigger assembly, a gas spring assembly, and a latch assembly is disclosed. The trigger assembly is moveable between an uncocked position and a cocked position. The gas spring assembly includes a compression cylinder and a piston moveable between an uncompressed position and a compressed position. Movement of the piston from the uncompressed position into the compressed position couples the latch assembly to the trigger assembly and the piston of the gas spring assembly. The latch assembly includes a locking portion that mechanically interlocks with a recess disposed on an interior surface of the piston to couple the latch assembly and the piston together. Actuation of the trigger assembly de-couples the latch assembly from the trigger assembly, permitting longitudinal movement of the latch assembly, which de-couples the latch assembly from the piston of the gas spring assembly.
