Title:
DRIVING APPARATUS FOR BIDIRECTIONAL CLUTCH-TYPE OPERATION
Document Type and Number:
WIPO Patent Application WO/2018/093068
Kind Code:
A1
Abstract:
The present invention relates to a driving apparatus for a bidirectional clutch-type operation, which enables a winding operation of an object to be wound to be smoothly performed when a winding operation of the object to be wound acts in a direction opposite to gravitational action. That is, the present invention provides a clutch-type operation driving apparatus comprising: a one-way clutch having an object to be wound fixedly coupled between a fixed shaft and a brake drum in a rotational direction of gravitational action; a clutch spring that is elastically and tightly coupled to the brake drum; an output shaft coupled to the clutch spring such that rotation thereof is restricted by the clutch spring; and an input shaft coupled to the clutch spring such that the clutch spring is deviated and rotated from the fixed shaft. Therefore, the present invention has an effect that the brake drum is pre-rotated by the one-way clutch provided between the fixed shafts when the object to be wound is moved in the opposite direction of gravitational action by the rotation of the input shaft, so that the rotation of the input shaft is smoothly operated.
