Patent Searching and Data

Document Type and Number:
Japanese Patent JP2007056808
Kind Code:

To provide a display having a wind power generation device of simple structure capable of converting a provided torsional vibration energy into an electric energy by effectively utilizing weak wind from any direction and preventing a wind receiving vane from being damaged or ruptured by a strong wind when the wind receiving vane receives the force of the strong wind exceeding the wind force resistance.

This display comprises a power generating unit formed of the wind receiving vane formed long in cross-sectionally V-shape or circular arc-shape perpendicular to the longitudinal direction and generating torsional vibration when its recessed surface side receives a wind force with its longitudinal one end held and its other end released and a power generation plate having a piezoelectric and a light emitting body. The display further comprises a wind receiving vane protective mechanism having a magnetic pedestal member supporting the power generation plate, a permanent magnet attracting the pedestal member installed on a base by a magnetic force, and a hinge-like member installed on the pedestal member so that the pedestal member can be attached to and detached from the permanent magnet.
