ABSTRACT:
A remotely-actuated fireworks launcher apparatus includes a housing assembly, a signal receiver housed within the housing assembly, an ignition servo electrically connected to the signal receiver and housed with the housing assembly, and a servo-actuated ignition switch operated by the ignition servo. The servo-actuated ignition switch is in an ignition circuit which also includes an electric igniter assembly, and a power supply. A fireworks receiver assembly is attached to the electric igniter assembly. The fireworks receiver assembly receives a fireworks device that is ignited by the electric igniter assembly. A manually operated ignition signal transmitter is actuated to transmit signals for activation of the signal receiver. The servo-actuated ignition switch includes a first switching element operated by the ignition servo and a second switching element selectively connected to or disconnected from the first switching element. The signal receiver receives electromagnetic waves, and the manually operated ignition signal transmitter transmits electromagnetic waves. In a second embodiment, a receiver-tilt servo is controlled by the signal receiver. A manually operated tilt signal transmitter is actuated to transmit signals for activation of the receiver-tilt servo. A tilting assembly is connected between the receiver-tilt servo and the fireworks receiver assembly. A pivot assembly is connected between the housing assembly and the fireworks receiver assembly. The receiver-tilt servo receives electromagnetic waves, and the manually operated tilt signal transmitter transmits electromagnetic waves.
