Abstract: The purpose of the present invention is to provide the clutch module for the hoist device having the enhanced braking and smooth driving for producing compact, easy by using cheap materials comprising: a manual pulley; a first clutch member with a wrap spring integrally formed with the engaging portion; a clutch stator having a first spring friction surface and fixed to the bracket; a driving member including a first driving rotor and a first driving rotor to release the frictional braking force between a spring friction surface of the clutch stator and a wrap spring inner diameter of the clutch stator in the direction the body of the wrap spring as a clutch member rotates when the manual pulley rotates; Up member for increasing the frictional braking force between the clutch stator and the clutch member by pushing the engaging portion of the clutch member in a direction to the wrap spring body of the clutch member is narrowed when the rotational force of the power transmitting portion of the hoist device is

Abstract: The present invention relates to the sunshade driving device comprising that: a returning function of a manual driving module (410) is actuated by a ball chain or a rotating string; a rotating shaft (491) is attachable/detachable to the power drive unit or the rotating shaft stopping unit separated from a manual driving module; at least one pick-up member (452, 453) to directly drive the sunshade rotating shaft or driving the rotating shaft (491) by the manual drive module (410); a wheel driving member (417) having a manual pulley (417a) or a manual driving wheel (412b) being fitted the ball chain or rotating string; wherein the wheel drive member (417) will be engaged to the manual rotating wheel (412b) and the manual pulley (417a) for rotating together in one direction, and the wheel driving member (417) will disengaged the manual rotating wheel (412b) and the manual pulley (417a) for independently rotating each other in opposite direction activated by a bi-directional driving clutch (417b).

Abstract: The present invention relates to the sunshade driving device comprising that: a returning function of a manually driving module (410) is actuated by a ball chain or a rotating string; a rotating shaft (421) is attachable/detachable to the power drive means or the rotating shaft stopping means separated from a manual driving module; at least one pick-up member (452, 452?) to directly drive the sunshade rotating shaft or driving the rotating shaft (421) by the manual drive module (410); a wheel driving member (415?) having a manual pulley (415a) or a manual driving wheel (412b) being fitted the ball chain or rotating string; wherein the wheel drive member (415?) will be engaged to the manual rotating wheel (412b) and the manual pulley (415a) for rotating together in one direction, and the wheel driving member (415?) will disengaged the manual rotating wheel (412b) and the manual pulley (415a) for independently rotating each other in opposite direction activated by a bi-directional driving clutch (415b).

Abstract: A new concept of the light guide device has developed to have multi channels, the present invention comprises: a transparent body through which light can freely pass; channel condensing units disposed at predetermined intervals on the body to form a plurality of one-dimensional arrays; an optical module unit for independently sighting incident light, and re-sighting and focusing light which passes through the one-dimensional arrays formed by the channel condensing units disposed at predetermined intervals in the body; and a fiber channel module for creating independent light passages (fiber channels) which condense light from the left, right, up and down aspects of the optical module unit, at a one-to-one correspondence between the body and the optical module unit. The present device maximizes the efficiency of the solar energy utilization by reducing the guide distance of incident light.
