Document Type and Number:
Japanese Patent JP2005273300
Kind Code:
A
Abstract:

To provide a locking device for an opening/closing body of a building capable of accurately operating a security system assembled with the locking device by constituting to obtain the amount of power generation scores of times as much as the previous invention by the rotating operation of a locking rotation body for conducting locking/unlocking of the locking device disposed at the opening/closing body.

A piezoelectric generator for the locking device capable of locking/unlocking the opening/closing body such as a window or a door of the building is composed of at least one piezoelectric ceramic body formed in plate shape; a cushioning material for holding the piezoelectric ceramic body in a soft state; a base member formed of a spring material; a steel ball supporting elastic body fixed to the end of the base member; and steel balls fixed to both ends of the steel ball supporting elastic body. The locking rotation body of the locking device disposed at one opening/closing body is rotationally operated to rotate a striking body disposed at a shaft of the locking rotation body to thereby impart external force to one of the steel balls. The other steel ball thereby repeats vertical vibration continuously by resonant action.
