Title:
BLIND
Document Type and Number:
Japanese Patent JP2012011055
Kind Code:
A
Abstract:

To perform different operations shielding materials with one operation code, and to reduce the size of an operation device with a fewer number of components in a blind having two shielding materials.

The blind includes: an operation shaft 46 which rotates by transmitting the operation force; an oscillation member 48 which can oscillate in the rotation direction of the operation shaft 46 following the rotation of the operation shaft 46; an intermediate member 52 which is rotatably supported by the oscillation member 48, to which the rotation of the operation shaft 46 is transmitted; and first and second transmission members 56, 58 which are arranged so as to be engaged with the intermediate member 52 on an oscillation trajectory of the oscillation member 48, respectively. The first transmission member 56 and the second transmission member 58 can transmit the rotation to the first drive shaft 26 and to the second drive shaft 36, respectively. The intermediate member 52 is engaged with one of the first and second transmission members 56, 58 in the oscillation direction of the oscillation member 48 which switches according to the rotation direction of the operation shaft 46. The rotation of the operation shaft 46 is transmitted to one of the first and second drive shafts 26, 36.
