Claims

[Scope of utility model registration request]

On each side of a row of horizontal slats arranged vertically at regular intervals, there is a pair of vertical link rows connected vertically by a pivot, and one vertical link row in each vertical link row.
A ladder-shaped link mechanism consisting of a large number of horizontal links that horizontally connect the pivots of each slat is arranged, and the shafts protruding from each side edge of each slat are attached to the center of the horizontal links. The upper end of the vertical link row is attached to a rotating member rotated by an upper horizontal operating shaft, the slat is rotated by rotating the operating shaft, and the slats are hoisted and lowered by rotation of the operating shaft. In a blind slat lifting and rotating device, the lower end of the lifting chain is connected to the lower end of the link mechanism, and the slats are raised and lowered by winding up and lowering the lifting chain. A stopper is provided to stop the extension of the link mechanism when the link mechanism is extended, and at the lowest end of the link mechanism, a first guide member having a long groove in an inclined direction and a shaft rotatable relative to the first guide member are provided. 1. A blind lifting and rotating device comprising: a connecting mechanism having a second guide member having a long groove in the vertical direction; and a lower end of a lifting chain slidably attached to the long groove of the guide member.
