PURPOSE: A manual power transfer device with a multi-shaft and a movable awning or latticed guardrail using the same are provided to selectively control the angle of inclination and to move slats or blades up and down. CONSTITUTION: A manual power transfer device with a multi-shaft comprises a gear(40) for selectively driving a driven shaft, a crank lever(30), an one-stage gear assembly(50) and a two-stage gear assembly. The gear for selectively driving the driven shaft comprises a drive gear shaft(41), locking holes(44,45,46,47), a shaft fixing unit(48), first and second driving gears. The locking holes are formed in one end of the drive gear shaft. The first and second driving gears are separately placed from the other end of the drive gear shaft. The shaft fixing unit comprises a bearing(49b) and one end of the drive gear shaft. The crank lever fixes one end of the drive gear shaft. The one-stage gear assembly comprises an intermediate gear(51), an one stage driven gear(54), one stage helical gears(52,53), and an one-stage driven gear for a sunshade(55). The one stage helical gears are engaged between the intermediate gear and the one-stage driven gear. The one-stage driven gear for the sunshade is fitted into the one-stage driven gear. The two-stage gear assembly comprises the intermediate gear, a two-stage driven gear, a two-stage helical gear, and a two stage driven shaft for tilting a slat or a blade. The two-stage driven gear is engaged with one of the two-stage helical gears. The two stage driven shaft for tilting the slat or blade is fitted into the two-stage driven gear. |
