ABSTRACT:
A magnetically driven wind chime apparatus includes a first outdoor pendulum assembly mounted on the outside of a window or other barrier and a second indoor pendulum assembly mounted on the inside of the window or other barrier. The outdoor pendulum assembly includes a first support body, a first pendulum rod having one end pivotally connected to the first support body, and a first magnetic pendulum mounted to a second end of the first pendulum rod. The indoor pendulum assembly includes a second support body, a second pendulum rod having one end pivotally connected to the second support body, and a second magnetic pendulum mounted to a second end of the second pendulum rod. A sail is mounted on the first pendulum rod. A wind chime assembly is connected to the second pendulum rod. The outdoor and indoor pendulum assemblies are mounted such that the first and second magnetic pendulums are in opposing relationship with their magnetic fields aligned so that each exerts a mutual magnetic repulsive (or attractive) force on the other. In this way, the outdoor pendulum assembly imparts motion to the indoor pendulum assembly as the sail is moved by a wind. The indoor pendulum assembly in turn imparts motion to the wind chime assembly as the indoor pendulum assembly is moved by the outdoor pendulum assembly.
