Claim 1
Independent Claim
173 words
A lighted floating disc toy comprising: a floating disc body; a plurality of lamps mounted at spaced points on said body; a source of electrical energy; energizing means for energizing said lamps from said source intermittently; said energizing means comprising a multi-vibrator connected between said source and said lamps; said multivibrator comprising a capacitor and a resistor and first and second NAND gates, each having at least two inputs, the output of the first gate being connected to a first input of the second gate through said capacitor, and a second input of the second gate being connected through said resistor to the output of said second gate and the inputs of the first gate; said multivibrator further comprising a path through a resistor for discharging said capacitor; and means in the form of at least first, second and third separate exposed terminals, and a flip-flop, for rendering said energizing means effective and ineffective, selectively, in response to simultaneous touching of said first terminal and one of said second and third terminals, respectively.
