Title:
OPERATIONAL SPRING ENERGY STORING DEVICE
Document Type and Number:
Japanese Patent JP3272190
Kind Code:
B2
Abstract:
PURPOSE: To permit a person to operate a switch freely upon changing over to the manual mode in case a motor has stopped while an operational spring is in the process of energy storage.
CONSTITUTION: A drive roller 24 in contact with an energy accumulating lever 11 and a guide roller 22 to be engaged by a slide shaft 25 are installed on a slider 21 which slides in engagement with a screw shaft 15, and the slider 21 is fitted with a resetting spring to give such a torque as setting off the contact with the energy accumulating lever. Engagement with and separation from the lever 11 is made by conditioning if the slider 15 is to be rotated or moved straight relative to the rotational motion of the screw shaft 15, and thereby the energy accumulation of the operational spring 12 is performed.
