Title:
BLOW-BACK
Document Type and Number:
Japanese Patent JP3250379
Kind Code:
B
Abstract:
PURPOSE: To provide a highly interesting blow-back which can be used for game.
CONSTITUTION: When air is blown into a pipe 6 through the blow hole 7 of the blow-back, the bodies 2a, 3a of blow-back parts 2, 3 having spring wires 2b, 3b with a low elastic modulus, of blow-back parts 1, 2, 3, 4, 5, are first extended (the 'scissors' state where the forefinger and the middle finger are stood). When air is further blown to enhance the air pressure in the pipe 6, the bodies 1b, 4b, 5b of the blow-back parts 1, 4, 5 having spring wires 1a, 4a, 5a with a high elastic modulus are extended (the 'paper' state where the five fingers are stood). When no air is blown, all the blow-back parts 1-5 are contracted (the 'stone' state where the fingers are bent). Thus, scissors, paper and stone are formed by the pressure of the blowing air, and utilized for a game.
