BLIND TYPE SHUTTER
Document Type and Number:
Japanese Patent JP3291911
Kind Code:
B
Abstract:
PURPOSE: To make the operation of link trains smooth by making the engaged part of a tilt arm in contact with a guide member during closing operation, displacing first and second link trains relatively to each other, and rotating a vane connected to them and obtaining lighting.
CONSTITUTION: When a motor 57 is actuated and a wheel 52 is rotated in A direction, a link train 3 and a vane plate 2 are delivered and an open part is closed. Next a tilt arm 69 is delivered immediately before the open part is fully closed, and a roller 89 is made in contact with a guide face 70 and the arm 69 is rotated in B direction. Also a shaft 81 is rotated in B direction, and a link train 64 connected through an arm mechanism is pulled out relative to the link train 3. Then a link member 61 in the downstream of the arm 69 is pulled out, and the vane plate 2 is rotated horizontally so that light can be obtained. In addition, when the wheel 52 is rotated, the rotation of the arm 69 is released, and the vane plate 2 is closed in vertical direction. Thus the link trains can be moved smoothly, and assembled and maintained easily.
