  • Patent number: 4324405
    Abstract: A game board includes an electrical circuit grid underlying a playing surface having a plurality of paths for game pieces each capable of being electrically activated by being placed in a circuit with grid elements disposed in the path along which the game piece is moved. An electrically actuated piece produces a visual and/or audible indication to a player that the game piece is in electrical contact with a "live" portion of the circuit grid. Whether a particular portion of the grid is or is not "live" is determined by the location of a circuit selector switch which closes or opens electrically distinct areas of the grid when operated by a player in accordance with instructions received from a spinner whose operation is governed entirely by the laws of chance. Advancement of the playing pieces along their paths is effected by players according to the instructions received from the spinner, after the circuit selector has been adjusted to a new position.

  • Patent number: 4298199
    Abstract: Disclosed is a game in which a game piece is suspended on a string and is preferably formed as the simulation of a bee or other insect attractable to a flower. The game piece is dangled by the player in a playing area simulating the portion of the flower bounded by the perianth. The perianth includes a series of trap elements formed in the simulation of petals and pivotally mounted on the base for swinging movement between open positions in which they expose the playing area to permit the game piece to be suspended therein, and closed positions in which they trap the game piece. In the playing area a centrally disposed trigger member has a connection to the trap elements such that on upward movement of the trigger member, the trap elements will be biased instantly to the positions in which they trap the game piece.

  • Patent number: 4187703
    Abstract: A container in the form of a flat envelope, open at one end for insertion and removal of a slide, has a series of locking keys shiftable laterally to left or right from a normal, centered, rest position. When all the keys have been shifted in predetermined directions to positions representing a pre-set combination, the slide is freed for partial removal from the envelope, to an unlocking position that permits the object to be removed or in some cases to gravitate freely from the envelope. The device can be made inexpensively of injection molded plastic or plastic-coated cardboard, cheaply enough to allow it to be made as a single-use, disposable article.
