ABSTRACT:
A safety device for a toy gun has first and second firing pins which can block movement of a trigger. The firing pins are electro-magnetically operated. The first firing pin is normally in a position which blocks movement of the trigger and the second firing pin is normally in a position which allows movement of the trigger. A power source is connected to the first firing pin by a switch so that trigger movement is blocked by the first firing pin until the switch is activated. The switch also connects the power source to a photo-electric switch which includes a light emitter and a light sensor. The second firing pin is connected to the power source by the photo-electric switch so that movement of the trigger is blocked by the second firing pin only when the photo-electric switch is closed. The photo-electric switch detects the presence of a target within a preset range of the toy gun and closes if a target is detected. In this way, the toy gun can be fired only if the first switch is closed and the photo-electric switch is open, i.e. no target detected in range. A preferred embodiment includes a lamp in series with the first firing pin and a buzzer in series with the second firing pin. The photo-electric switch is preferrably infra-red.
