Abstract

Provided are an operation cord which can smoothly turn and has a fail safe function, and a lifting device using the operation cord. An operation cord (9) which can be changed to an endless form by connecting at a connecting section (20) opposite ends of a cord (14). The connecting section (20) is configured such that the outer diameter in the lateral direction thereof is the same as or less than the maximum diameter of the cord (9).

Description

technical field [0001] The invention relates to a control pull cord suitable for horizontal shutters, vertical shutters, roller blinds, screen windows, up and down sliding windows, awnings, skylights or clothes poles and a lifting device using the same. Background technique [0002] As one type of horizontal blinds, there are the following blinds. That is, the ring-shaped control pull cord is suspended and installed on the pulley rotatably supported on one end of the control mechanism cover, and the pulley can be rotated by manipulating the control pull cord to perform lifting operation and angle adjustment operation on the louvers. . Moreover, the technique which operates a vertical blind by rotating an operation cord around a pulley is also known (refer patent document 1). [0003] Such a manipulation cord is, for example, a cord formed into a ring shape by welding or sewing both ends of a cord formed into a button shape made of synthetic resin. Such a control cord can ...
