昇降装置。 In a blind lifting device that uses an operation cord to rotate the winding shaft in the forward direction to lower the blind and rotate it in the opposite direction to wind up the blind, there is a device integrated with the winding shaft 2 on one side of the winding shaft 2. Rotating drive cylinders 20 and 28 are provided, and the drive cylinders 20 and 28 are rotatably supported by fixing members 11 and 30 that are non-rotatably provided with respect to the support fitting 4b that supports the winding shaft 2, and the drive cylinders 20 and 28 are rotatably supported. Members 11, 30 and the drive cylinder 2
Coil springs 18, 31, which usually fit into the fixed members 11, 30, are provided between the coil springs 18, 31, and both ends of the coil springs 18, 31 are bent to form engaging ends 19a, 19b, 32a, 32b.
The drive tubes 20 and 28 are provided so that the drive cylinders 20 and 28 can be driven by the transmission means 17 and 26 which are rotationally driven by the operation cord 16, and when the transmission means 17 and 26 rotate, the coil springs 18 and 31 are connected to the fixed members 11 and 26. 30
The drive cylinders 20, 28 are separated from the transmission means 17.
, 26, and can rotate integrally with the blind 1.
When the rotational force in the positive direction is applied to the driving cylinders 20 and 28 due to the weight of the driving cylinders 20 and 28, the driving cylinders 20 are
, 28, and a rotational force acting in the opposite direction separates the coil spring from the fixing members 11, 30 to allow rotation of the drive cylinders 20, 28. 32b
A blind lifting/lowering device characterized in that these are engaged with transmission means 17, 26 and drive cylinders 20, 28, respectively.
