  • Patent number: 8671926
    Abstract: A toy launcher apparatus having inner and outer concentric tubes forming a chamber between the tubes. Within the inner tube in a piston and an attached rod, the piston being movable between front and rear positions by a user of the launcher apparatus. The other end of the rod is attached to a handle and upon being pulled rearward, compressed air causes discharge of a projectile. The inner tube has a closed front end portion and an open rear end portion with vents. An end cap is connected to the tubes to prevent relative movement between the tubes and to provide an air path from a region in the inner tube rearward of the piston, through the vents and into the chamber. A front cap is attached to the outer tube, a projectile restraining seal is mounted to the front cap, and a perforated cup is mounted rearward of the seal. A spring is positioned in the chamber between the inner tube and the perforated cup to bias the cup and a loaded ball toward the seal.

  • Patent number: 8402958
    Abstract: The wheel also includes an opening in the third portion leading to a chamber in a hollow support of the wheel. A spring-biased knob is mounted on a shaft that also mounts the wheel. Both the knob and the wheel have axially align protrusions that may engage each other to allow the wheel to be rotationally adjusted to correct any jam or misalignment of the darts stored on the wheel. A flexible arm and a pusher structure are also included with the magazine apparatus and are connected to a constant force spring, where the flexible arm and a portion of the constant force spring are lodged in the chamber of the hollow support during a dart loading process of the wheel, and the constant force spring uncoils when the wheel is rotated during the loading process.

  • Patent number: 8057309
    Abstract: A toy capable of interchangeably activating an electronic controller and a projectile launching component through the same trigger mechanism providing for a fun and interesting toy with a variety of play modes. A holder assembly including a receiving compartment is capable of accepting the electronic controller and the projectile launching component. The electronic controller includes at least one human user interface input button for controlling an electronic game, and the projectile launching component includes a mechanical actuator for launching a projectile. The trigger mechanism is in mechanical communication with the holder assembly for engagement with the human user interface input button for controlling the electronic game and the mechanical actuator for launching the projectile.

  • Publication number: 20110041823
    Abstract: A toy dart magazine apparatus that includes a housing divided into a drum portion and a clip portion, and a wheel structure rotatably mounted to the drum portion. The wheel has four portions, two spaced apart portions having peripheral recesses for receiving the darts and storing them until they are “fired” by a launcher to which the dart magazine apparatus is mounted. A third portion having a smooth circumference and a smaller diameter than the two recess bearing portions wherein the third portion separates the two spaced apart portions. The fourth portion of the wheel has a larger diameter than the two recess bearing portions and is positioned adjoining one of the two recess bearing portions for aligning the darts relative to the wheel. The wheel also includes an opening in the third portion leading to a chamber in a hollow support of the wheel. A spring-biased knob is mounted on a shaft that also mounts the wheel.
