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.

Disclosed is an endless operation code which can be replaced readily. Specifically disclosed is an operation code comprising a main code having a first end and a second end, a first connection part arranged at the first end, and a second connection part arranged at the second end, wherein the first connection part and the second connection part can be connected to each other directly or through a connection member and can be removed by relative rotation to each other or relative movement to each other on a direction that is different from the lengthwise direction of the main code.

PROBLEM TO BE SOLVED: To provide a shielding material hoisting and lowering device of a solar radiation shielding device which does not impede behaviors of residents, etc. and can prevent unexpected damage of the hoisting and lowering device.SOLUTION: In the solar radiation shielding device, a lifting cord is attached to the lower end part of a shielding material hanging down from a headbox and the shielding material is ascendable/descendable by operation of the lifting cord. The lower end of the lifting cord 5 is attached to a lower end part of the shielding material 2 via a connection member 11, the connection member 11 being composed of a first connection member 14 attached to the lower end part of the shielding material 2 and a second connection member 13 attached to the lower end of the lifting cord 5. The first connection member 14 and the second connection member 13 are held by holding means which is disconnected by a tensile force exceeding the weight of the shielding material 2 acting on the first connection member 14.

PROBLEM TO BE SOLVED: To provide a shielding device which enables an intermediate rail and a bottom rail to be each independently operated for ascent and descent, and which can surely prevent the occurrence of a sag in a lifting and lowering cord for the intermediate rail when the intermediate rail is pushed up by the bottom rail. SOLUTION: This shielding device includes an intermediate clutch 41 which takes up the first lifting and lowering cord 6 by rotatively driving a first drive shaft 11 in synchronization with a second drive shaft 12, when a load of the intermediate rail does not act on the first drive shaft 11.
