  • Patent number: 4802677
    Abstract: A game arrow and is specifically concerned with providing a game arrow which is adapted to be launched by a hand held whip-like wand and string assembly which is substituted for the conventional bow and arrow. Such bow and arrow assemblies require a great amount of strength by the shooter in order to flex the bow sufficiently to provide a sufficient shooting force. This problem is overcome by the game arrow and launching device of the present invention which is able to launch an arrow by a movement similar to that employed when shooting a slingshot which does not require even a fraction of the amount of strength necessary for shooting a conventional bow and arrow. Furthermore, attempts to provide a slot in a conventional wooden arrow have not been successful because of the substantial weakening of the shaft of the arrow by the slot which frequently cannot withstand even the slightest shock forces during normal use.

  • Patent number: 4789163
    Abstract: The present invention relates to an indoor horseshoe pitching game and is specifically concerned with providing an electronically controlled game which closely simulates the structure and method of play of the traditional outdoor game. Other electronic games such as bowling, darts and the like, utilize playing pieces which have no correspondence whatsoever to the playing pieces used in the original games and have no further correlation with respect to the degree of skill necessary from the original to the simulated game. Serious safety hazards also exist when bringing the outdoor game into the more confined fragile environment of the indoors when the horseshoes employed are of such a shape and form that their bounce or roll cannot be readily predicted upon striking or landing upon any unimproved receiving surface.
