Abstract: A ball game device including a plurality of hole cups each provided with a bottom plate and embedded in an undulatory game surface, a bottom plate lifting mechanism attached to each hole cup for raising and lowering the bottom plate of each hole cup, in a straight line movement, between a predetermined position below the game surface and a second position flush with the game surface, and sequence control elements for controlling the actuation of the bottom plate lifting mechanisms so that the plurality of hole cups are successively selected one at a time in such a manner that only one hole is formed in the game surface by only one hole cup thus selected each time. The sequence control elements include a holing detector photoelectric or electromagnetic induction switch associated with each of the cups.

Abstract: A balloon neck fitting to be attached to the neck of a balloon sold by a balloon vending machine. The balloon neck fitting consists of a check valve section and a guide section, and these two sections, though initially joined together, will be separated from each other when the associated balloon is inflated and delivered from the vending machine. The check valve section is fitted in the neck of a balloon and serves to prevent backward flow of the gas from inside the inflated balloon, while the guide section serves as a guide when the neck fitting is moved within the vending machine. The check valve and guide sections separated from each other have been tied together by a string and the guide section serves as a hook for the finger when the purchaser carries with him the balloon.

Abstract: A balloon vending machine to accommodate inside a number of non-inflated balloons in advance and to offer the inflated balloons one by one upon demand.
