  • Patent number: 11959721
    Abstract: A manually operated toy pneumatic launcher for launching a ball projectile. The pneumatic launcher has a housing with a first section and a second section that move relative to each other. At least one handle extends from the second section that rotates through a range of motion. A base tube is affixed to the second section. A launch tube is affixed to the first section. The launch tube extends into the base tube creating a telescoping tube assembly. A mechanism is provided that is powered by the handle moving through its range of motion. The mechanism includes a gear box, a lever arm, and a slide that act together to linearly move the first section of the housing relative to the second section. This selectively changes the length of the telescoping tube assembly, therein enabling the telescoping assembly to compress and release air in the launching of the projectile.

  • Patent number: 11885586
    Abstract: An assembly for launching toy projectiles includes a body having a bore, a plunger extendable from the bore, and a shaft removably attachable to the body. The body includes a first recess having a first diameter for receiving a first projectile. The shaft includes a second diameter for receiving a second projectile therearound and a second recess having a third diameter for receiving a third projectile therein. The first diameter is substantially equal to a diameter of the first projectile, the second diameter is substantially equal to a diameter of the second projectile, and the third diameter is substantially equal to a diameter of the third projectile but smaller than the second diameter. The plunger drives air through the assembly when released from an extended position to eject any one of the first, second, or third projectiles positioned in the first recess, on the shaft, or in the second recess.

    Abstract: An example simulated weapon includes a delayed trigger and a pellet ejector. The delayed trigger includes a chamber and a piston slidable between armed and triggering positions. A spring biases the piston towards the triggering position. A locking member releasably locks the piston in the armed position. Release of the piston by the locking member causes the spring to move the piston from the armed position to the triggering position. The pellet ejector is coupled to the delay trigger to be triggered by the delay trigger in the triggering position. The pellet ejector includes a pressure chamber to receive a pressurized fluid and a pellet chamber to receive pellets. A valve is disposed between the pressure chamber and the pellet chamber communicates pressure from the pressure chamber to the pellet chamber. A barrel that extends through the pressure chamber is connected to the pellet chamber to eject the pellets.

  • Patent number: 5901693
    Abstract: A toy gun for launching a foam projectile from a launch station that is offset from the axis of the launcher. The gun includes a pneumatic launcher having a retractable plunger that reciprocates in a cylinder to define a compression chamber. One or more air ports are provided to communicate air from the compression chamber to the launch station in order to eject a projectile therefrom. The plunger incorporates a hollow shaft having transparent ends which are aligned with the transparent compression chamber, thus providing a continuous line of sight through said shaft and the compression chamber for aiming the gun toward an intended target.

  • Patent number: 5775312
    Abstract: A spring air gun includes a reciprocable piston and a slide for cocking the piston. The slide is movable between forward and rearward positions. A piston rod is connected to the slide and is slidably mounted within a piston tube which is connected to the piston. A pair of springs are concentrically mounted on the piston tube, and the forward end of each spring engages the piston. The rearward end of the inner spring engages the slide, and the rearward end of the outer spring engages the frame of the gun. A detent maintains the slide in the forward position, and a sear maintains the piston in the cocked position and is engageable with the detent for preventing the slide from moving rearwardly until the gun is fired. The gun is fired by pulling a trigger, which releases the sear from the piston. The detent can then be moved to allow the slide to be moved rearwardly to cock the piston. When the slide is not in the forward position, the detent prevents the trigger from being pulled.
