Toy light sword
First Claim
Patent Images
1. A toy light sword comprising:
- an elongated, hollow, transparent blade;
a handle connected at one end of said blade;
flash lamp actuating means mounted to said handle;
a DC power source;
enabling switch means for selectively connecting said DC power source to said flash lamp actuating means for energization thereof;
high-intensity flash lamp means in said hollow blade for emitting a burst of high-intensity light when actuated by said flash lamp actuating means, said flash lamp means lighting the full length of said blade for a short duration, said blade appearing as a long, thin, short duration, glowing sword when viewed externally upon actuation of said flash lamp means; and
trigger switch means for selectively applying the energy in said flash lamp actuating means to said high-intensity flash lamp means to fire said lamp means;
said flash lamp actuating means comprising;
storage capacitor means connected across said flash lamp means;
means connected to said flash lamp means for triggering said flash lamp means into conduction;
oscillator means coupled to said source of DC power;
a DC/AC inverter connected to the output of said oscillator means;
an AC/DC converter and voltage multiplier connected between said DC/AC inverter and said storage capacitor means;
a feedback network;
comparator means connected between said feedback network and said oscillator; and
means for coupling the voltage output from said voltage multiplier to said feedback network, said comparator means actuating said oscillator means when a predetermined reduction in the voltage on said storage capacitor means is detected;
whereby said storage capacitor means is maintained at a desired voltage level sufficient to actuate said flash lamp means as desired.

Abstract
A toy light sword including a hollow blade with a fluorescent coating on the inside, or it may be translucent and tend to glow when illuminated. A stroboscopic lamp unit is discharged by a switch to provide a burst of high intensity light and a glow on the sword blade. An inertial switch is provided in the blade in one optional embodiment whereby the high-intensity light is discharged when the sword is moved against an object to indicate that contact has been made. Also, a sound generator can be provided to emit a sound when the burst of light occurs. An exemplary circuit for use with the light sword is also part of the invention.
