Title:
OPERATION DEVICE FOR SOLAR SHADING DEVICE, LIFTING DEVICE FOR ROLL-UP SHADE, AND OPERATING PULLEY
Document Type and Number:
WIPO Patent Application WO/2011/129345
Kind Code:
A1
Abstract:
Provided is an operation device for a solar shading device such that there is provided a fail-safe function, that the movements of a resident or the like are not hindered, and that during normal operations, unnecessary activation of the fail-safe function is prevented, resulting in making it possible to improve operability. This operation device for the solar shading device is configured in such way that an endless operation cord is suspended from a pulley which is rotatably supported in a head box, and that drive shafts are driven into rotation via the pulley on the basis of an operation of the operation cord, resulting in shade members being driven. In said operation device, the operation cord (16) is made endless by being connected by a connecting section which becomes disconnected under a preset first tensile force; and between the pulley (15) and the drive shafts (11, 12), there is interposed a torque limiter (18) that runs idle under a second rotational torque which is lower than a first rotational torque provided by the first tensile force to the pulley.
