Title:
POWER GENERATOR FOR DOOR
Document Type and Number:
Japanese Patent JP2023127216
Kind Code:
A
Abstract:
To provide a power generator for a door, which generates power when the door is opened/closed and which can be easily installed in various doors such as a sliding door not equipped with a knob.SOLUTION: This power generator for doors comprises: a generator 70; a spiral spring 50; an input shaft 30A; a winding-up power transmission mechanism 40; and a power transmission mechanism for power generation 60. The winding-up power transmission mechanism winds up the spiral spring while the input shaft is rotated forward, and releases a winding-up shaft while the input shaft is rotated backward. The power transmission mechanism for power generation transmits a rotating force of the winding-up shaft to a power generation shaft, driving the generator, while the winding-up shaft is rotating in a releasing direction. One of gears of the winding-up power transmission mechanism is disengaged from a gear to which power is next transmitted while the input shaft is rotating backward. One of gears of the power transmission mechanism for power generation is disengaged from a gear to which power is next transmitted while the winding-up shaft is rotating in a winding-up direction.SELECTED DRAWING: Figure 5
