  • Patent number: 4900026
    Abstract: An interactive action game involving the selective collection of colored balls has a housing which supports a concave bowl with an electric battery motor driven foam paddle at the center of the concave surface. As the balls drop down to the center of the bowl, the balls contact the rotating foam paddle and are whirled about the concave surface of the bowl. Disposed over the top of the spinning foam paddle is a central shield. The top of the shield may contain a number of indentations, or separate pieces may be provided with indentations into which the players place the collected colored balls in a pattern to win the game.

  • Patent number: 4897065
    Abstract: A toy vehicle and a handheld pneumatic launcher combination includes a piston and an elongated hollow cylinder with a flange adjacent one end of the cylinder providing grips for a child which simulate an airplane control yoke. While supporting lateral extensions of the flange with the fingers of each hand, the child's thumbs are free to press upon an actuator at one end of the piston forcing the piston head into the cylinder. Attached at the other end of the elongated cylinder, in pneumatic communication with the cylinder, is a launch tube that fits into a socket adjacent the bottom of a toy vehicle that is made predominantly of a lightweight plastic foam. The axis of the launch tube is preferably offset from the axis of the cylinder. In addition, the launch tube is tapered and has a closed end with perforations through the sidewalls of the tube adjacent the closed end.

  • Patent number: 4690658
    Abstract: A toy vehicle launcher having a hand grip which can be squeezed to move expandable scissors members forward in order to launch a toy vehicle. The scissors members form an expandable parallelogram linkage which is slidable mounted inside the launcher. When the hand grip is squeezed, a trigger member pivotably mounted to the grip moves a sliding plate mounted inside the launcher. As the sliding plate moves, two pins attached to the sliding plate operably engage elongated slots in two of the scissors members, pulling the two members backward and causing the linkage to expand forward. A launching plate supported on top of the scissors members moves forward with the expanding linkage pushing a toy vehicle forward. Since the linkage expands forward in a relatively smooth and uniform manner, the toy vehicle is also launched in a relatively uniform manner, helping to avoid activating or damaging any impact-activated mechanisms in the vehicle.
