Abstract:
A highly durable operation cord. A cord having both ends connected together by a connection section, wherein the connection section is provided with first and second connection sections connected together directly or through a connection member, either of the connection section and a connection member which are adjacent to each other has an engaging protrusion, the other has an engaging hole engageable with the engaging protrusion, and the engaging protrusion is a solid body.
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.

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 lifting device comprising an operating cord having excellent durability.SOLUTION: A lifting device comprises: a support frame; a pulley supported rotatably by the support frame; an endless operating cord wound around the pulley; a winding shaft rotated by a rotation of the pulley; and a shading material lifted up and down, and the operating cord comprises: a main cord including one end and the other end; a first connection part provided to the one end; and a second connection part provided to the other end, where the first and the second connection parts are capable of being connected to each other directly or via a connection member and also capable of being connected to adjacent connection part or connection member by inserting a fitting protrusion of one of them into a fitting port of the other of them, and the fitting protrusion is a solid.
Abstract:
PROBLEM TO BE SOLVED: To provide an operation cord including a fail-safe function.SOLUTION: This operation cord 9 is formed into an endless shape by connecting both of end parts of a cord 14 in a connection part 15. The connection part 15 includes a first connection member 17 and a second connection member 18 being separable from each other by action of the tensile force exceeding the tensile force acting on the operation cord while the operation cord 9 is usually operated and connection cords 19, 23 for connecting the first and second connection members 17, 18 with the end parts of the cord 14.

Abstract:
PROBLEM TO BE SOLVED: To provide a fixing device of shading equipment, which enables a head box to be supported between opposed mounting surfaces without the use of a mounting screw, and which enables a tool to be easily stored. SOLUTION: The shading equipment is equipped with the fixing device for detachably fixing the head box between the opposed mounting surfaces by performing the operation of switching an urging force of an urging means. A retainer member for being engaged with the fixing device is provided between the fixing device and the mounting surface. The retainer member 32 is provided with a storage part 38 in which the tool 31 for performing the operation of switching the urging means can be housed. COPYRIGHT: (C)2007,JPO&INPIT
